          validity checking.  Nicknames, channel names and usernames
          can now include practically any kind of letters and various
          other characters.  Affected files in silcd/ and in libraries.

          NOTE: comparing these strings should now be done with memcmp()
          to check binary compatibility.  All these strings are normalized
          and casing is irrelevant.

        * Added silc_identifier_check to lib/silcutil/silcstrutil.[ch]
          as easy function for applications to check whether identifier
          strings are valid.

          will occur.  Affected file lib/silccore/silcpacket.c.

        * Use the rekey period time as rekey protocol timeout value.
          If the rekey does not succeed during the rekey period there's

        * Save old channel keys in list to allow more rapid change
          of channel keys if server for some reason does that.  This
          avoids loosing so many channel messages due to not having
          key to decrypt.  Affected file lib/silcclient/silcclient.h,
          idlist.c and client_channel.c.

Mon Oct 13 21:37:47 EEST 2003  Pekka Riikonen <priikone@silcnet.org>

          lib/silcutil/silctypes.h.

        * Use the SILC_SWAB_16 instead of htons() in server when
          handling ports since the ports in structures are always
          in little-endian order (regardless of platform).  Affected

          Fixed also various memory leaks around the config file
          parser.  Affected files lib/silcutil/silcconfig.c,
          silcd/serverconfig.c.

        * Changed my nickname (Johnny Mnemonic) to my real name, this
          means that bugs introduced by him were actually introduced
          by me!

Tue Jan  7 21:58:53 CET 2003  Jochen Eisinger <c0ffee@penguin-breeder.org>

        * Don't display "foo appears as foo\nYou're now known as foo"

          command by checking the command reply status correctly.
          Affected file lib/silcclient/command_reply.c.

Tue Dec 17 10:05:00 CET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed file writing on WIN32 to use O_BINARY flag.  Affected
          file is lib/silcutil/silcfileutil.c.  A patch by Matthew
          Aldous <Matthew@Aldous.com>.

        * Added better implementation using CriticalSection of
          SilcMutex on WIN32.  A patch by Mikko Lähteenmäki
          <mikko.lahteenmaki@pikabaana.net>.

        * Added some Winsock WIN32 compatiblity defines into
          includes/silcwin32.h.

        * Fixed double free in async host lookup code.  Affected file
          lib/silcutil/silcsockconn.c.

        * On backup router handle now the SERVER_SIGNOFF from router
          for local connected servers too, and close the connections.

          Do not process them as normally signing off servers when they
          really signoff by sending EOF fe, but always assume that
          router sends the SERVER_SIGNOFF.

          Affected files silcd/server.c and silcd/packet_receive.c.

        * Fixed socket unsetting when closing connections.  Affected
          files silcd/server.c and silcd/packet_send.c.

        * Do not print the nickname in SERVER_SIGNOFF if we do not
          have it.  Prevents asserts in Irssi core.  It is possible we
          don't have the nick if it was just being resolved when server
          signoff.  Affected file irssi/src/silc/core/client_ops.c.

Thu Dec 12 23:22:50 EET 2002  Pekka Riikonen <priikone@silcnet.org>

          lib/silcutil/unix/silcunixmutex.c.

        * Fixed locking in silc_schedule_uninit.  It didn't lock
          when dispatching timeout tasks.  Affected file is
          lib/silcutil/silcschedule.c.

        * Changed Win32 implementation of SilcThread to use modern
          Win32 interface.  Affected file is
          lib/silcutil/win32/silcwin32thread.c  A patch by Mikko L.

          server connections.  Affected file silcd/idlist.c.

        * Check for NULL outbuf in silc_socket_write.  It is possible
          that it is NULL is some odd case.  Affected files are
          lib/silcutil/[unix/win32]/silc[unix/win32]sockconn.c.

        * Do not call final protocol callback for backup router
          resuming protocol when closing connection.  It is closed
          by timeout in case of error.  Affected file silcd/server.c.

        * Backup reconnect to router if backup resuming protocol
          failed.  Affected file silcd/server_backup.c.

Wed Dec 11 10:01:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

        * Fixed double free in SKE library error hadling when signature
          error occurred.  Affected file lib/silcske/silcske.c.

        * Save the fingerprint to new SilcClientEntry after changing
          nickname.  Affected file lib/silcclient/client_notify.c.

        * Print SIGNOFF in Irssi SILC client only if the nickname is
          known.  Prevents asserts in Irssi core.  It is possible we
          don't have the nick if it was just being resolved when it
          quit.  Affected file irssi/src/silc/core/client_ops.c.

Tue Dec 10 21:47:56 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed double free in invite list adding code when adding
          invite strings.  Affected file silcd/server_util.c.

Fri Dec  6 17:40:24 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * More log printing during backup router protocol.  Affected
          file silcd/server_backup.c.

        * Removed backwards support for old private key file format.
          Affected file lib/silccrypt/silcpkcs.c.

        * Removed backwards support for not-so-strict decryption length
          check, it's strict now.  Affected lib/silccrypt/silccipher.c.

        * GETKEY to update the client entrys fingerprint too.
          Affected file lib/silcclient/command_reply.c.

Thu Dec  5 22:29:46 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed backup router bugs:  When backup resumes router and
          receives a CHANNEL_MESSAGE packet the backup must not act
          as router since the packet header decryption would be
          different.  Also, when relaying packets to channel, do
          not re-encrypt packets on backup that came from the primary
          since the connection isn't really router-router connection.
          Affected files silcd/server.c, silcd/packet_send.c.

        * Added checks in encryption/decryption that encryption/decryption
          length sent as argument really is multiple by block size.  Helps
          catching really weird bugs like the above backup router bugs
          when packets are being decrypted in wrong way.  Affected files
          lib/silccore/silcpacket.c, and lib/silccrypt/silccipher.c.

        * Fixed padding generation in private key file encryption.
          Affected file lib/silccrypt/silcpkcs.c.

Thu Dec  5 16:35:23 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added ignore_message_signatures setting which can be used
          to ignore signatures in messages.  Affected files are
          irssi/src/silc/core/client_ops.c, silc-core.c.

        * Fixed the libtoolfix to use command line options instead of
          environment variables.  They didn't work as expected.  Now,
          the libtool is fully run-time configurable.

Wed Dec  4 21:08:52 CET 2002  Jochen Eisinger <c0ffee@penguin-breeder.org>

        * Verify signature payload for signed messages. Affected files

          irssi/src/fe-common/silc/module-formats.[ch],
          irssi/src/fe-common/silc/fe-common-silc.c,
          irssi/src/fe-common/silc/Makefile.am
          irssi/src/fe-common/core/fe-messages.[ch]

        * Added support to backup router protocol for backup to tell
          normal server that it cannot use the backup router as primary
          because the primary isn't really down.  Updated protocol
          specs.

        * Added support for primary router to tell backup router that
          resuming is not possible because the backup really isn't primary
          in the cell.  For example if backup disconnected itself the

        * Deprecated the No Reply flag in SKE protocol and introduced
          "IV Included" flag which can be used to indicate that the IV
          is included in the ciphertext.  This makes it possible to use
          SILC on unreliable transport, such as UDP which may cause
          packet reordering and losses.  Updated protocol specs, did
          not implement yet.

        * Defined the SILC_MESSAGE_FLAG_SIGNED.  Updated protocol specs
          and added initial implementation.

        * Added MAC field to the Private Message Payload to protect
          against chosen ciphertext attacks.  Updated the protocol specs
          and implemented.

        * Added idle and signon fields to the ATTRIBUTE_SERVICE
          attribute to indicate the user's current idle and signon time

          to know about the signoff.  Affected file silcd/server_util.c.

        * Use the primary router as the origin of the locally connected
          server when it is disconnecting from the backup router since
          that's where it really is coming from.  Now the clients from
          the disconnecting server are removed correctly and "shadow"
          clients are not left to the backup router.  Affected file
          silcd/server.c.

Sat Sep  7 22:26:50 EEST 2002  Pekka Riikonen <priikone@silcnet.org>

        * If normal server is standalone and found existing but disabled
          channel, do not re-create the channel since it creates
          duplicate same channels.  Affected file silcd/server.c.

        * Added anonymous client connections support to server.  New
          "anonymous" configuration option to ConnectionParams section
          added.  If set to true, the username and hostname information
          of the client will be scrambled and anonymous user mode is
          set automatically to the user.  Affected files are
          silcd/serverconfig.[ch], silcd/packet_receive.c and server.c.

Sat Sep  7 16:02:09 EEST 2002  Pekka Riikonen <priikone@silcnet.org>

        * In JOIN notify handling, mark that the cache entry of the
          client cannot be expired.  Can cause crashes on normal
          server (asserts client->channels).  Affected file is
          silcd/packet_receive.c.

        * From now on distribution versions are used as protocol versions
          instead of by default using the Toolkit base version as protocol
          version.  Affected file prepare.

        * Do not set the locally resolved hostname for local client
          entry but take what server sends.  This way the real hostname
          is showed in WHOIS for yourself.  Affected file is
          lib/silcclient/idlist.c and lib/silcclient/client.c.

        * Resolve local info with IDENTIFY when connecting to server.y

Sat Sep  7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>

        * Rewritten check for POSIX threads.  Use --with-pthreads[=DIR]
          for implied search (not needed on platforms which has native
          pthreads library).  Use --without-pthreads to disable threads.
          Affected file is configure.in.pre

        * Fixed --with-iconv on platforms which need to bypass (broken)
          native iconv().  Affected file is configure.in.pre

Sat Sep  7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Moved -C option parsing in Irssi SILC client at same time
          as other options.  The UI was initialized earlier and caused
          problems on command line.  Bug #16.  Affected file is
          irssi/src/silc/core/silc-core.c.

Mon Sep  2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>

        * Added global variable silc_log_timestamp that tells silclog
          wether to print or not the timestamp in the logging files.
          Affected file lib/silcutil/silclog.[ch].

        * Added silcd configuration option Timestamp in the Logging
          section.  Affected file silcd/serverconfig.[ch],
          doc/example_silcd.conf.in.

Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Fixed fingerprint checking to check for entirely empty
          fingerprint instead of two first bytes when determining
          if it is set.  Bug #18.  Affected file silcd/command.c.

        * Fixed duplicate PKCS name registering to not allow it.
          Bugs #17.  Affected file lib/silccrypt/silcpkcs.c.

Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>

        * Conditionalize non-gcc compiler optimizations for various
          platforms, enable those commented out.  Cleanups.
          Affected file lib/silcmath/mpi/configure.in

Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>

        * silc_rng_exec_command() left zombie processes if command
          didn't generate any output.  Affected file
          lib/silccrypt/silcrng.c

Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>

        * Rewrote iconv checking, introduce --with-iconv for systems
          which rely on libiconv.  Check if iconv() provided by libc
          is good enough, otherwise demand libiconv.  Affected file
          configure.in.pre

Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>

        * Search for ldopen() also in libc.  This enables SIM support
          on *BSD systems.  Based on patch from Alex Zepeda.  Affected
          file configure.in.pre

Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>

        * Don't call AM_CONDITIONAL conditonally for SILC_THREADS.
          This fixes prepare on *BSD systems.  Affected file
          configure.in.pre

Sun Aug  4 15:55:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * More fixed for not having purge timeout for global clients
          that are on channel.  Affected files silcd/command_reply.c
          and server_util.c.

        * Fixed the rekey protocol to work with backup router connections.
          Rekey packets are now allowed on disabled connections as
          well.  Affected files silcd/packet_send.c and server.c.

        * Do not switch to be as backup router when shutting down and
          closing the primary connection.  Affected file silcd/server.c.

        * Fixed memory leaks in backup router deleting.  Added
          silc_server_backup_free to free all data during shutdown of
          server.  Affected files silcd/server_backup.[ch].

Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Do not process commands if the sock->user_data is NULL.
          Affected file silcd/command.c.

Tue Jul  9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Fixed buffer overflow and security problems (loosing bits
          in CFB encryption) in SILC RNG.  Problems reported by
          Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.

Sun Jul  7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Added yet more checks that client is not expired on global
          list if it is on channels.  Affected file is
          silcd/command_reply.c.

Sat Jul  6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Merged c0ffee's MIME signal patch which adds support for
          sending also MIME messages in Irssi SILC Client, and handling
          received MIME messages in a signal (and perhaps doing something
          to non-textual MIME messages).

Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Fixed pending command deletion in server and client library
          to check the whole list instead of breaking after first found.
          The affected files are silcd/command.[ch] and
          lib/silcclient/command.[ch].

Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Return NO_SUCH_CHANNEL error in USERS for channel that is
          secret or private, otherwise it's possible to find out
          whether a secret channel exists or not.  Affected file
          silcd/command.c.

        * If CMODE change fails during the mode setting, assure that
          the old mode mask is set for the channel back.  Affected
          file silcd/command.c.

        * Fixed passphrase saving on +a channel on normal server
          after successful JOIN command.  Affected file silcd/command.c.

Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Remove server/router operator privileges in DETACH command,
          since it's possible to resume to server where these
          privileges would not be allowed for the client.  Affected
          file silcd/command.c.

        * Do not set to wait for backup in rehash of the server.
          Affected file silcd/server.c.

        * Do not check listener sockets when counting how many
          socket connections we have.  Affected file is
          silcd/server_util.c.

        * Do not announce disconnected clients that are remaining
          in history (for WHOWAS).  This is because SIGNOFF notify
          for these has been sent earlier already.  Affected file
          silcd/server.c.

Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Buffer overflow with CUMODE command's mode->mode character
          conversion.  Reported by Ville Räsänen.  Affected file
          lib/silcutil/silcutil.c.

Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Allow heartbeat packets to go disabled connections anyway.
          Affected files silcd/server.c and silcd/packet_send.c.

        * Do not broadcast New Channel packets with List flag set
          in the packet to backup routers.  The router must check
          for the correctness of the packets before sending them.
          It is possible that router will have enforce Channel ID
          change and this would cause desync in the backup router.
          Affected file silcd/packet_receive.c.

        * Remove SILC_PACKET_FLAG_LIST from the temp packets that
          are handled in list parsing.  They are not list packets
          anymore.  Affected file silcd/packet_receive.c.

Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Stop waiting for backup router through the timeout, not
          directly after backup router has arrived.  Affected file
          silcd/server.c.

        * Do not re-create channel keys and send them when removing
          clients in server shutdown.  Affected files are
          silcd/server_internal.h and silcd/server_util.c.

        * Notify distribution to backup routers was missing from
          the silc_server_send_notify_dest function which caused
          desyncing problems with backup router.  Affected file is
          silcd/packet_send.c.

        * The client's channel removing was working wrong on
          backup router.  It assumed that it doesn't know global
          information but backup router does know.  For this reason
          it could remove channel when it wasn't supposed to do that.
          Affected file silcd/server.c and silcd/server_util.c.

Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Stop for a couple seconds after badkup router has become
          primary router.  Affected file silcd/server.c.

        * Added silc_server_remove_servers_by_server, which is used
          to remove servers originated from some other server.  Also
          clients of those servers can be removed too.  Affected file
          silcd/server_util.[ch].

        * When removing clients after a server has signed of remove
          also all servers behind that server (unless they are known
          to be available locally), and send SERVER_SIGNOFF for each
          of the server separately.  Also the signed off clients are
          sent now separately per signed off server.  The affected files
          are silcd/server.c and silcd/server_util.[ch].

        * All servers added with silc_idlist_add_server must always
          have both "router" and "connection" pointers set.  Otherwise,
          bad server entries may be left around in the cache.
          Affected file silcd/command_reply.c.

        * Do not create the channel key in NEW_CHANNEL packet
          processing if the channel is empty.  Affected file
          silcd/packet_receive.c.

        * Completed backup router support for standalone routers.
          Supports also servers in the cell that do not use the backup
          at all.

Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Fixed a bug in silc_string_regexify which did not add '^'
          at the start of each string, and thus the matching was
          not explicit.  For example ban list iikone@*!*@* would
          match also "priikone", which is wrong, it would have to be
          *iikone@*!*@* to match also "priikone".  Affected
          file lib/silcutil/unix/silcunixutil.c.

Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Enable all local server connections before updating client
          caches when we've become backup router.  Otherwise, signoff
          packets may not reach the clients.  Affected files are
          silcd/server.c and silcd/server_util.[ch].

        * Fixed a bug in version string parsing which could crash
          the program with specially formatted version string.
          Bug reported and patch provided by Ville Räsänen.  Affected
          file lib/silcutil/silcutil.c.

        * Handle the disconnection immediately when DISCONNECT
          packet is received in server.  Affected file silcd/server.c.

        * Primary router now waits a short time (10 seconds) for
          backup router connection before accepting any other
          connection (except local).  Affected file silcd/server.c,
          serverconfig.[ch].

        * Fixed a crash in client libary in NICK_CHANGE notify when
          NICK_CHANGE arrived for client entry we are resolving
          currently.  Affected file lib/silcclient/client_notify.c.

        * Call the sconn->callback completion even if error had
          occurred.  Start reconnecting always if connection to
          primary router fails during backup router protocol.
          Affected files silcd/server.c and server_backup.c.

Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Added functions silc_server_send_opers and
          silc_server_send_opers_notify to send packets stricly
          to operators.  Added macro SILC_SERVER_SEND_OPERS macro
          to send variable argument notify to operators.
          Affected files silcd/packet_send.[ch] and silcd/server.h.

        * Removed UMODE rights checking with UMODE_CHANGE notify.
          Affected file silcd/packet_receive.c.

        * Server/router operator now receives notify when network
          switches to backup router and when it resumes the use of
          primary router.  Affected file silcd/server.c and
          silcd/server_backup.c.

        * Fixed the updating of client information after backup
          resuming protocol is over; update all except local clients
          to the new primary router.  The affected file is
          silcd/server_util.c.

        * Added support for closing active connections in rehash
          that were unconfigured by the user.  Supports currently
          closing server and router connections.  Affected file
          silcd/server.c.

        * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.

Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
          is NULL since seems that on some platforms NULL is allowed
          and on some it's not.  Fallback encoding is used instead.
          Affected file lib/silcutil/silcstrutil.c.

        * Fixed statistics updating for incoming server connection
          which could cause problems when re-connecting.  Affected
          file silcd/server.c.

        * Preliminary backup router support for standalone router
          added.  Affected files in silcd/.

        * Mark server connections in backup router disabled before
          and after backup protocol.  Affected file is
          silcd/server_backup.c.

        * Added support for reconnecting to remote server connection
          even if the protocol fails, and if the configuration wants
          us to keep trying to connect anyway.

          Server connection is not allowed to backup router if
          backup router does not have connection to primary router yet.

          Affected file is silcd/server.c.

Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Added silc_client_udpate_server function to update changed
          server info.  Affected file lib/silcclient/idlist.[ch].

        * Added check for server entries that are being resolved when
          notify is received.  If being resolved, handle the received
          notify only after it's resolved so that all notifys are
          handled in same order as received from the server.

          Added similar resolver check to channel entries.  Every
          notify that cause resolving of any information that affects
          channel entry marks the channel entry in waiting state.
          After whatever resolving is over the waiters are signalled
          and only then the notifys are handled in the same order
          as delivered from the server.

          Affected files are lib/silcclient/idlist.[ch], and
          client_notify.c.

        * Fixed KILLED notify handling in normal server.  Affected
          file silcd/packet_receive.c.

        * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
          is locally connected, or was locally connected (but may
          be detached and connection is not active).  Added also
          SILC_IS_LOCAL for checking this status.  Affected files
          silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
          silcd/server.c and silcd/server_internal.h.

Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Don't send or handle TOPIC_SET if topic is already set and
          is same as being set.  Affected files silcd/command.c and
          silcd/packet_receive.c.

        * Fixed CMODE change rights checking to work correctly when
          removing modes by operator.  Affected file is
          silcd/server_util.c.

        * Fixed some handling with New Channel packet in router and
          fixed some CMODE_CHANGE notify handling in server and router.
          Affected file is silcd/packet_receive.c.

        * Changed "disconnect" client operation to include the
          reason of the disconnection and optional disconnection
          message.  Affected file lib/silcclient/silcclient.h.

        * Made the compilation of lib/contrib/ stuff conditional.
          Affected files configure.in.pre, lib/contrib/Makefile.am.

Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
          to the sender of the notify too, to avoid situation where two
          notifys are in the network at the same time going to oppsite
          directions.  Affected file silcd/packet_receice.c.

Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Delete the client from channel even if the cilent->id is
          NULL.  It was possible that client was deleted without
          removing from channels (theoretically at least).  Affected
          file silcd/server.c and silcd/server_util.c.

        * Free the client data too when resuming is not successful.
          Affected file silcd/packet_receive.c.

        * Merged some code from c0ffee's silc-plugin.  Affected files
          irssi/src/silc/core/silc-channels.c and silc-expandos.c.

        * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
          silcd/server_internal.h.  SILC_PRIMARY_ROUTE Returns pointer
          to the primary router connection, the other one returns
          TRUE if packet must be broadcasted to network.

        * All notifys that are destined to primary router (to network)
          are now automatically sent to backup routers even if the
          router is standalone (and has backup router).  Affected files
          in silcd/.

        * Added --without-irssi and --without-silcd configuration
          options for disabling the compilation of these applications.
          Affected file configure.in.pre and prepare.

Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Implemented SILC_STRING_BMP and SILC_STRING_UNIVERSAL for
          UTF-8 encoding and decoding.  Added also new encodings
          SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.

          Added also SILC_STRING_LANGUAGE which is language and charset
          specific encoder and decoer for those platforms that support
          iconv().  It can convert the UTF-8 to and from the locale
          specific character set.

          Affected file lib/silcutil/silcstrutil.[ch].

        * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.

        * Added function silc_get_command_name to the file
          lib/silcutil/silcutil.[ch].

        * Improved the server debug output a bit.  Affected files are
          in silcd/.

        * Save the channel passphrase when received succesful JOIN
          command reply from router, on normal server.  Otherwise
          joinig +a channels from normal server is not possible.
          Affected file silcd/command.c.

        * Fixed a bug in TOPIC_SET notify handling.  The notifier
          may be other than client too, like server or channel.
          It expected it to always be only client and ignored the
          notify.  Affected file silcd/packet_recieve.c.

        * Removed some (unnecessary) debug printing from
          lib/silccore/silcid.c and lib/silccore/silcargument.c.

        * Do not force CMODE_CHANGE when server is announcing new
          channel.

          Router announces stuff only after server reannounces channel
          after CHANNEL_CHANGE notify.

          These fixes optimizes the announcing procedure, and perhaps
          fixes some problems too.  Affected file silcd/packet_receive.c.

        * Fixed SERVER_SIGNOFF sending to local clients.  It was
          totally broken and sent the notify to all local clients,
          instead of only to those that was on same channel as the
          signing off clients.  Affected file silcd/server_util.c.

        * Added -D option to server.  It can be used to give debug
          level.  The levels are from 0 - 99, and are predefined for
          smooth server debugging.  (see silcd.c for the predefined
          levels).  Affected file silcd/server.c.

Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

          channel.  Affected file silcd/command.c.

        * Better checking for founder mode setting when CUMODE_CHANGE
          notify is received.  Affected file silcd/packet_receive.c.

        * Close all connections when shutting down the server by sending
          DISCONNECT packet.  Close all listeners too when shutting
          down the server.  Affected file silcd/server.c.

        * Handle DISCONNECT packet correctly in client library by
          calling the "disconnect" client operation.  Affected file
          lib/silcclient/client.c.

        * Handle local errors correctly during resuming.  Affected
          file lib/silcclient/client.c.

        * Added SILC_MESSAGE_FLAG_UTF8 to the protocol specs and the
          core library, and implemented it.  All textual messages SHOULD
          use this flag and the message MUST be UTF-8 encoded.
          All text messages sent by Irssi SILC client are now UTF-8
          encoded (regardless whether the terminal supports UTF-8 or not).
          Affected files are lib/silccore/silcchannel.h,

          The one that authenticated will become founder and anyone
          else is demoted.  Affected file silcd/command.c.

        * Added error printing of any error that has occurred during
          any command in client library.  Affected file is
          irssi/src/silc/core/client_ops.c.

        * Removed some error printing from the client library and left
          it for the application to worry (from the error status it
          receives in 'command' client operation.  Affected file is
          lib/silcclient/command.c.

Fri Jun 14 22:59:02 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

Mon Jun 10 09:28:21 CEST 2002 Pekka Riikonen <priikone@silcnet.org>

        * Made the private key generation after expiration optional.
          If not created after expiration the old key will re-expire
          at a later time (and thus key pair is not necessary to
          change).  Affected file irssi/src/silc/core/clientutil.c.

Sun Jun  9 18:58:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

          Affected files are lib/silccore/silccomand.h,
          lib/silccore/silcnotify.h, lib/silcclient/command[_reply].[ch],
          silcd/command[_reply].[ch], lib/silcclient/client_notify.c,
          silcd/packet_send.[ch], silcd/packet_receive.c, and
          irssi/src/silc/core/client_ops.c.

        * Added user mode SILC_UMODE_REJECT_WATCHING to reject

          code.  Affected files are lib/silccore/silcmode.h, and
          lib/silcclient/command.c.

Fri Apr 19 09:02:20 CEST 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added service support to SILC protocol.  Added new command
          SILC_COMMAND_SERVICE.  Updated the protocol specs and the
          core library.  Services are not implemented in server or
          client for now.  Protocol TODO #20.  Affected files are
          lib/silccore/silcstatus.h, lib/silccore/silccommand.h.

        * Added SilcStatus argument to `command' client operation
          to return the error status when command sending fails
          locally.  Changed all command in client library to return
          correct command status.  Affected files are
          lib/silcclient/command.c, lib/silcclient/silcclient.h and
          irssi/src/silc/core/client_ops.c.

Thu Apr 18 14:09:51 CEST 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added silc_mime_parse function to parse MIME headers.
          Affected files are lib/silcutil/silcstruti.[ch].

        * Added MIME header parsing in Irssi SILC Client.  It displays
          all textual MIME objects, others it ignores.  Affected file
          is irssi/src/silc/core/clien_ops.c.

Wed Apr 17 22:07:59 CEST 2002  Johnny Mnemonic <johnny@themnemonic.org>

        * Fixed a bug in the pid writing function, which couldn't be
          written in a root-owned directory.

Tue Apr 16 09:34:40 EEST 2002  Pekka Riikonen <priikone@silcnet.org>

        * Defined that channel message to unknown Channel ID must
          cause SILC_NOTIFY_TYPE_ERROR notify message to the sender.
          Updated the protocol specs and the code in server.  The
          affected file is silcd/packet_receive.c.

Mon Apr 15 19:57:57 EEST 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added new notify type SILC_NOTIFY_TYPE_ERROR and specified
          that it is used to send error notifys if error occurs during
          some SILC packet processing, except commands.  The error
          types are same as for command reply types.  Defined that
          if private message is sent to unknown Client ID the error
          is sent in SILC_NOTIFY_TYPE_ERROR instead of command reply.
          Updated the protocol specs and code.  Affected files are
          lib/silccore/silcnotify.h, added lib/silccore/silcstatus.h,
          lib/silcclient/client_notify.c, silcd/packet_receive.c,
          and irssi/src/silc/core/client_ops.c.  Renamed the
          SilcCommandStatus to SilcStatus.

        * Defined the use of extra WHOIS attributes in WHOIS command.
          The <Requested Attributes> (defined in a separate document)
          can be used to request additional information about user
          not returned by standard WHOIS command.  Defined that server
          can send WHOIS command directly to client.  Client provides
          the requested attributes to the server.  Updated the protocol
          specs.  Protocol TODO #4.  Implementation is not done yet
          (Protocol TODO #24).

        * Renamed function silc_client_command_status_message to
          silc_client_status_message.  Affected files are

          32 bit integers.  Updated the protcol specs and the code.
          Affected files are silcd/command.c and
          lib/silcclient/command.c.

Sun Apr 14 19:49:02 CEST 2002  Johnny Mnemonic <johnny@themnemonic.org>

        * Fixed a bug in library where sending a bogus authentication
          payload would lead to a crash.  Affected file is
          lib/silccore/silcauth.c.

Sat Apr 13 13:09:24 EEST 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added detach_disabled and detach_timeout server config
          options to the server.  Affected files silcd/serverconfig.[ch],
          silcd/command.c and silcd/packet_receive.c.

Fri Apr 12 20:09:08 EEST 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added resolve_cmd_ident field to the SilcClientEntry structure
          too so that if the entry is for example being resolved so
          another command may attach to the same pending command reply
          without requiring to resolve the same entry again.  Added
          support for adding multiple pending commands for one
          command idenfier.  Affected files lib/silcclient/command.[ch],
          lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.

Fri Apr 12 10:17:51 EEST 2002  Pekka Riikonen <priikone@silcnet.org>

          and secret channels too.  Updated protocol specs and the
          code in server.  Affected file silcd/command.c.

        * Defined <channel user mode list> argument to WHOIS command
          reply for returning user modes on the channels.  The
          channel list now doesn't include the user mode anymore but the
          actual channel mode.  Updated protocol specs and the code in
          client and server.  Affected files are silcd/command_reply.c,
          silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
          and lib/silcclient/command_reply.c.

        * Save the channels list in WHOIS command reply in normal server
          so that WHOIS always shows joined channels also in normal
          server and not just on router.  Affected file is
          silcd/command_reply.c.

Thu Apr 11 22:29:33 EEST 2002  Pekka Riikonen <priikone@silcnet.org>

        * Defined that server receives USERS command reply for private
          and secret channels too.  Updated protocol specs and the
          code in server.  Affected file silcd/command.c.

Thu Apr 11 16:32:08 EEST 2002  Pekka Riikonen <priikone@silcnet.org>

        * Changed the UMODE's mode mask argument to be optional.  If
          not provided then the command merely returns the current mode
          mask to the client.  Updated protocol specs and the server.
          Affected file is silcd/command.c.

        * Added SILC session detachment/resuming support.  It is possible
          to detach by closing the network connection and then re-connect
          and resume to the old client session.  Added DETACHED user
          mode that server will set for detached client.  Added new
          packet RESUME_CLIENT which is used to perform the resuming
          process.  Added DETACH command.  Updated the protocol specs,
          core library, client and server.  Protocol TODO #22.  Very
          many affected files around the tree.

Wed Apr 10 16:32:01 EEST 2002  Pekka Riikonen <priikone@silcnet.org>

        * Changed the CMODE's mode mask argument to be optional.  If
          not provided then the command merely returns the current mode
          mask to the client.  Updated protocol specs and the server.
          Affected file is silcd/command.c.

        * Changed the Killer's Client ID in KILLED notify to be just
          any ID payload since router server is allowed to kill as well.
          Updated protocol specs, client libary and server.  Affected
          files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
          and irssi/src/silc/core/client_ops.c.

Tue Apr  9 17:15:42 EEST 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added new user modes ANONYMOUS for special anonymous servers
          that may set the mode for client, and BLOCK_PRIVMSG which
          client may set to block incoming private messages unless the
          Private Message Key flag is set (using private keys to protect
          private messages).  Updated protocol specs and code in client
          and server and core library.  Protocol TODO #23.  Affected
          files are lib/silccore/silcmode.h, silcd/server.[ch],
          irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,
          irssi/docs/help/in/umode.in, lib/silcclient/command.c.

        * Added new channel user mode BLOCK_MESSAGES which the client
          may set to itself to tell server not send channel messages.
          Other packets such as channel key packets are still sent.
          Protocol TODO #23.  Updated the protocol specs, client and
          server.  Affected files are lib/silccore/silcmode.h,
          irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
          lib/silcutil/silcutil.c, silcd/command.c, and
          silcd/packet_send.c.

Mon Apr  8 23:57:32 EEST 2002  Pekka Riikonen <priikone@silcnet.org>

        * Redefined the Status Payload to include now two 8 bit fields,
          instead of one 16 bit field.  This now makes it possible to
          send list of errors.  Updated the protocol specs and the code
          in core library, client library and server.  Protocol TODO #1.
          Affected files are lib/silccore/silccommand.[ch],
          lib/silcclient/command_reply.[ch], silcd/command.c,
          silcd/command_reply.c and silcd/packet_receive.[ch].

Mon Apr  8 19:57:40 CEST 2002  Johnny Mnemonic <johnny@themnemonic.org>

        * Added config parse status SILC_CONFIG_EPRINTLINE, this status
          must be handled by the application and should tell the application
          that an error message was already printed, and it should print the
          config coords (line, filename, ...).  Affected files are
          silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].

        * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
          server config parsing code more readable.

          Fixed a bug in the fetch_logging() config callback.

          Affected files is silcd/serverconfig.c.

        * Drop root privileges when started in foreground.  Don't drop them
          if debugging also.  Affected file is silcd/silcd.c.

Mon Apr  8 17:00:41 EEST 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added more IM-like features by introducing new user modes
          for setting various presence information.  Added new modes:
          INDISPOSED, BUSY, PAGE, HYPER and ROBOT.  Updated protocol
          specs and code.  Protocol TODO #19. Affected files are
          lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
          irssi/docs/help/in/umode.in and lib/silcclient/command.c.

Sun Apr  7 17:07:59 EEST 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added STATS command to the protocol after all, to return
          various statistical information about the network.  It can
          be used by clients to retrieve statistical information, and
          servers may use it to to fetch cell and network wide
          statistics from router.  Updated the protocol specs and
          implemented it to the server.  Protocol TODO #16.
          Affected files are lib/silccore/silccommand, silcd/command.[ch],
          silcd/command_reply.[ch].

Sat Apr  6 17:08:58 EEST 2002  Pekka Riikonen <priikone@silcnet.org>

        * The LIST command reply in client libary now adds new channel
          entry if the returned channel doesn't exist yet in cache,
          and returns the channel entry to the application in the
          command_reply client operation.  Affected file is
          lib/silcclient/command_reply.c.

        * Changed the channel message payload's MAC generation to
          include the IV in the MAC as well.  This way all relevant
          parts of the channel message payload are authenticated also
          with the channel message MAC (and not only by packet MAC).
          Causes incompatibility with 1.0 protocol.  Protocol TODO #7.
          Affected file is lib/silccore/silcchannel.c.

        * Fixed the SKE to save the remote version, since the
          silc_ske_parse_version mistakenly checked wrong version,
          after it replaced the start payload.  Affected files are
          lib/silcske/silcske.[ch].

Fri Apr  5 16:03:03 EEST 2002  Pekka Riikonen <priikone@silcnet.org>

        * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
          string utility functions.  Added there also new functions
          silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
          Affected files lib/silcutil/silcstrutil.[ch].

        * Renamed silc_*_pem functions to silc_pem_* functions.  Affected
          files are lib/silcutil/silcstrutil.[ch].

        * Defined that the security property fields in SKE SHOULD be
          UTF-8 encoded, defined that version string MUST be US-ASCII
          encoded, defined that passphrases sent in connection
          authentication protocol MUST be UTF-8 encoded.  Implemented
          these to the client and server.  Defined also that other
          passphrases sent in the protocol MUST be UTF-8 encoded.
          Affected files are lib/silcske/silcske.c,
          lib/silcclient/protocol.c, silcd/protocol.c,
          silcd/serverconfig.c, and lib/silccore/silcauth.c.

        * Changed the silc_client_close_connection interface to not
          need the SilcSocketConnection which should not be visible
          to application.  Affected files are lib/silcclient/client.c
          and lib/silcclient/silcclient.h.

        * Rewrote the text for Private Message Key Payload in the
          protocol specification.  Protocol TODO #11.

Wed Apr  3 16:24:51 EEST 2002  Pekka Riikonen <priikone@silcnet.org>

        * Upgraded the protocol version to 1.1, updated protocol specs
          and software.

        * Added the nickname as new argument to NICK_CHANGE notify and
          added it to protocol specs and implemented it to client and
          server.  Protocol TODO #3.  Affected files are silcd/idlist.[ch],
          silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
          lib/silcclient/client_notify.c.

        * Added the killer's client ID to the KILLED notify and added
          it to protocol specs and implemented it to client and server.
          Protocol TODO #13.  Affected files are silcd/command.c,
          silcd/packet_receive.c, packet_send.[ch],
          lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
          The killer's client entry is now returned to application in
          the `notify' client operation.

        * Fixed the Max Argument fields that had too large value set
          in the protocol specs.  Protocol TODO #14.

        * Added the LEAVE command reply to return the ID of parted
          channel.  Updated protocol specs and implemented it to the
          client and server.  Protocol TODO #15.  Affected files are
          silcd/command.c, lib/silcclient/command_reply.c.  The channel
          entry is now returned to application in the `command_reply'
          client operation.

        * Rewrote the version SKE version checking in client libary
          and in server to use the silc_parse_version_string.  Affected
          files are lib/silcclient/protocol.c, silcd/protocol.c.

        * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
          commands that was missing it, and updated protocol specs and
          the server implementation.  Protocol TODO #10.  The affected
          file is silcd/command.c.

        * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
          generic reply to a generic request (REQUEST flag), and
          SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
          way.  A draft-riikonen-silc-flags-payloads-00.txt is written
          to define the payload for DATA flag.  Added the flags to
          the implementation.  Protocol TODO #9.  Affected file is
          lib/silccore/silcchannel.h.

          Changed the client library to return the message length
          to application as well in the channel_message and private_message
          client operations.  Affected files are
          lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
          lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
          and lib/silcclient/client_ops_example.c.

        * Added two new channel modes: SILC_CMODE_SILENCE_USERS
          and SILC_CMODE_SILENCE_OPERS which can be used to moderate
          the channel.  Updated protocol specs and impelemented this
          to client and server.  Protocol TODO #6.  Affected files are
          silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
          lib/silcclient/client_channel.c, lib/silccore/silcmode.h.

          Added new options m and M to CMODE command in Irssi SILC
          client to set these modes.

        * Deprecated all administrative commands from SILC protocol
          since they are highly implementation specific commands.
          Updated protocol specs.  Moved the old commands in
          implementations to private range of command types.  Affected
          files are silcd/command.c, lib/silcclient/command.c and
          lib/silcclient/command_reply.c.  Protocol TODO #8.

        * Fixed a bug in server where sending unknown command crashes
          the server.  Affected file silcd/command.c.

Wed Apr  3 09:57:47 CEST 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added SILC_PROTOCOLVERSION macro to check protocol version
          of a socket connection.  The affected file is
          lib/silcutil/silcsockconn.h.

        * Added better error logging in rekey protocol.  Affected file
          silcd/protocol.c.

        * Do not check public key types in SKE during rekey.  Affected
          file lib/silcske/payload.c.

        * Fixed the rekey protocol with PFS, which was totally broken.
          Affected file silcd/protocol.c.

Tue Apr  2 14:55:06 CEST 2002  Pekka Riikonen <priikone@silcnet.org>

        * Some client implementations quit network by doing first LEAVE
          and then immediately SIGNOFF (like Bombyx).  We now do check
          after a short time after LEAVE notify and check whether the
          client is still valid after LEAVE, and if not we remove it from
          cache.  Affected file is lib/silcclient/client_notify.c.

Tue Apr  2 13:39:04 CEST 2002  Johnny Mnemonic <johnny@themnemonic.org>

        * Merged version 1.1.4 of zlib. Even if it not currently in use,
          it's good not to have security holes here.

        * Fixed a negative refcount situtuation for the config context.
          Affected file is silcd/serverconfig.c.

Mon Apr  1 20:15:10 CEST 2002  Johnny Mnemonic <johnny@themnemonic.org>

        * ROBOdoc documented lib/silcutil/silcutil.h.

Sat Mar 30 21:06:45 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Optimized even more the SilcPacketContext structure.  Now
          totally saved 16 bytes of memory per context after optimization.
          Affected files are lib/silccore/silcpacket.[ch].

        * Made strict checks for valid SILC IDs.  Affected file is
          lib/silccore/silcid.c.

Sat Mar 30 18:15:55 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Changed the object argument for silc_cipher_register,
          silc_hash_register, silc_hmac_register and silc_pkcs_register
          to const.  Affected files are lib/silccrypt/silccipher.[ch],
          silchash.[ch], silchmac.[ch] and silcpkcs.[ch].

        * Changed the silc_get_username and silc_get_real_name to
          never fail.  Affected file lib/silcutil/unix/silcunixutil.c.

        * Fixed the Irssi SILC Client to use the silc_get_username and
          silc_get_real_name insted of glib routines since the glib
          routines only corrupt stack.  Fixes the Irssi SILC to work in
          Cygwin.  Affected file irssi/src/silc/core/silc-core.c.

        * Fixed the Irssi to not use g_get_home_dir since it crashes
          or returns garbage on cygwin and corrupts stack.  Added function
          get_home_dir to Irssi routines.  Affected files are
          irssi/src/core/misc.[ch] and irssi/src/core/core.c.

Fri Mar 29 21:55:41 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Made some structure optimizations.  SFTP memory FS MemFSEntry
          entry structure.  Optimized SilcTask structure.  Optimized
          SilcPacketContext structure.

          Affected files lib/silcsftp/sftp_fs_memory.c,
          lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.

Fri Mar 29 10:41:07 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * And yet again reverted back the config thing since Johnny
          screwed it up.  Affected file silcd/serverconfig.[ch], server.c,
          and silcd.c.

        * Fixed memory leaks from config object.  Affected files are
          silcd/serverconfig.[ch].

        * Added support for adding new connections to the server in rehash.
          After rehash they take effect.

          Added support for changing the maximum allowed connections in
          rehash.  The number can grow but going smaller is not supported.

          Added function silc_server_num_sockets_by_remote to the
          silcd/server_util.[ch].

          Affected files are silcd/server.c, and silcd/serverconfig.[ch].

Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

        * Added preliminary checking during config parsing for a valid
          public/private key and removed further checks in the code.
          Affected files are silcd/serverconfig.[ch], server.c.

        * Moved functions silc_server_drop() and silc_server_daemonise()
          from server.c to silcd.c since they are stricly related to
          the application activity.

        * Reverted a small part of the automatic ref/unref since
          it caused a double unref in some situations.  Affected
          files are silcd/silcd.[ch], server.c, serverconfig.c.

        * Added some .cvsignore files in the lib directory.

Thu Mar 28 22:51:15 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed silc_net_gethostbyaddr to correctly resolve by
          address.  Affected file lib/silcutil/silcnet.c.

        * Fixed the notify relaying to client.  The HMAC to be used
          with relayed packets ws wrong and caused decryption failure
          at the client end.  Affected file is silcd/packet_receive.c.

Thu Mar 28 19:02:05 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Created new branch silc_protocol_1_0_branch.

        * Reverted the silc_log_quick change in lib/silcutil/silclog.c.

        * Changed the silc_server_config_* routines to be SilcServer
          independent.  They are now officially application specific code
          and not part of generic server implementation.  Affected files
          are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.

Thu Mar 28 17:01:43 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added automatic referencing of config context in the
          silc_server_config_alloc, and automatic unreferencing in the
          silc_server_config_destroy.  Affected files are
          silcd/serverconfig.[ch], silcd/silcd.c.

        * Fixed the silc_log_quick handling in the logging routines.
          It didn't log quickly when it was TRUE.  Affected file is
          lib/silcutil/silclog.c.  Also the flush delay was set even
          if it was 0 in config file.  Affected file is
          silcd/serverconfig.c.

        * Added support for changing key pair of the server in rehash.
          Affected file silcd/server.c.

Thu Mar 28 12:17:21 CET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed the TOPIC_SET notify to not cras.  It changed the topic
          too early, before getting the channel entry.  Affected file
          is silcd/packet_receive.c.

Thu Mar 28 09:58:16 CET 2002  Johnny Mnemonic <johnny@themnemonic.org>

        * Added functions silc_server_config_[ref/unref], these are used
          to prevent that the config object is destroyed.

          No longer directly affect global variables silc_log_quick and
          silc_log_delay, they are first cached inside the config object
          and then applied with silc_server_config_setlogfiles().

          silc_server_config_set_defaults() is now internal to
          serverconfig.c, there are no reasons to show this internal stuff
          to the server.

          Affected files are silcd/serverconfig.[ch].

        * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
          fprintf's to stderr, since some code may be executed again after
          the server went into the background.  Affected files are
          silcd/server.[ch].

        * Added rehash support. Added function silc_server_rehash() that
          will perform all the basic tasks of the rehashing procedure.

        * Added command line option `-x, --hexdump'. This will enable the
          SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
          The option `--hexdump' implies `--debug'.

        * Fixed a bad bug in the logging APIs (silcutil library) where
          the application would crash after calling silc_log_reset_all().

Wed Mar 27 19:43:16 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed the KICKED notify handling in client library to
          correctly remove the channel and all entries from the
          channel when I was kicked.  This bug crashed the client.

          Fixed yet another but in KICKED notify handling to remove
          the kicked client correctly from the channel.

          Affected file is lib/silcclient/client_notify.c.

        * Fixed a minor bug in looking up correct client entry
          in KICKED notify in server.  Affected file is
          silcd/packet_receive.c.

        * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
          sources correctly to distribution.  Fixes --with-gmp option.

        * Removed the manual rehashing from ID Cache, and changed it
          to use the SILC Hash Table's auto rehash feature.  Affected
          file is lib/silccore/silcidcache.c.

Wed Mar 27 00:07:11 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed a bug in the silc_client_nickname_format function that
          handles the multiple same nickname formatting.  Two clients
          with same nickname caused problems after the first one left
          and rejoined.  It didn't format the nickname correctly.
          Affected file is lib/silcclient/idlist.c.

Tue Mar 26 19:33:03 CET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Don't change the topic if olod topic is same as new one.
          Affected file is silcd/packet_receive.c.

Mon Mar 25 21:11:35 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added cross-reference support to the SILC Documentation
          generator.  All types across all HTML files are now cross-
          referenced.  Affected files util/robodoc/generator.c and
          scripts/silcdoc/silcdoc.

        * Added file lib/silcutil/silctypes.h to include all the
          arithmetic type definitions and some macros.  Removed
          includes/bitmove.h and moved macros to silctypes.h.

Mon Mar 25 17:19:46 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Merged bugfixes for Irssi SILC client from irssi.org CVS.

Sun Mar 24 11:21:04 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added `type' argument to silc_id_payload_parse_id function which
          now returns the type of the ID to the sent pointer.  Affected
          file is lib/silccore/silcid.[ch].

        * Added check for CMODE_CHANGE notify type that mode change is
          allowed by the sender.  Affected file silcd/packet_receive.c.

        * Added check for CUMODE_CHANGE notify type that mode change is
          allowed by the sender.  Affected file silcd/packet_receive.c.
          Added the ID type as CUMODE_CHANGE notify type as argument
          to the `notify' client operation.  Affected files are
          lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.

        * Added function silc_client_add_server to the client library.
          Added support for resolving also channel and server info when
          received unknown entity in notify packet.  Affected files are
          lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.

        * Added function silc_command_get_status to return the command
          status from the command reply's argument payload.  Affected files
          are lib/silccore/silccommand.[ch].

        * Added check for KICKED notify type that the kicking is
          allowed by the client.  Affected file silcd/packet_receive.c.

        * Created function silc_get_input which can be used to get input
          (echo on or off) from user on command line.  Affected files are
          lib/silcutil/silcutil.[ch].

Sat Mar 23 09:51:26 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Optimized silc_server_packet_relay_to_channel function.
          Added new function silc_channel_message_payload_encrypt which
          can be called directly if channel message payload needs to
          be encrypted and is already encoded (no need to call _encode
          function).  Packet relaying is now done by router without any
          extra memory allocations.  Affected files are
          lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
          silcd/packet_send.c.

        * Fixed the INVITE notify handling.  It took wrong arguments
          as invite list and invite delete.  Affected file is
          silcd/packet_receive.c.

        * Added check for TOPIC_SET notify type that the topic change is
          allowed by the client.  Affected file silcd/packet_receive.c.

        * Added check for INVITE notify type that inviting is allowed by
          the client.  Affected file silcd/packet_receive.c.

        * Changed the silc_server_client_on_channel to return the
          SilcChannelClientEntry as well.  Moved the function
          silc_server_check_cmode_rights to server_util.[ch].
          Affected files are silcd/server_util.[ch], silcd/command.c.

        * Added function silc_server_check_umode_rights to check whether
          changing client's user mode is allowed.  Added check for
          UMODE_CHANGE notify type that the umode change is allowed
          by the client.  Affected files are silcd/server_util.[ch],
          silcd/packet_receive.c and silcd/command.c.

Fri Mar 22 12:25:58 CET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
          ID length.  It ignored that ID can be IPv6 based as well.
          Affected file lib/silccore/silcpacket.h.

        * Fixed the silc_id_id2str and silc_id_str2id to take the
          IPv6 address offset's into consideration.  Affecte file is
          lib/silccore/silcid.c.

Thu Mar 21 20:44:13 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed the internal Unix scheduler functions to check for
          NULL context they may receive.  The affected file is
          lib/silcutil/unix/silcunixschedule.c.

Thu Mar 21 19:12:22 EET 2002  Timo Sirainen <tss@iki.fi>

        * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
          can specify different directory with --home command line
          parameter. Affected files irssi/src/silc/core/client_ops.c,
          clientutil.c

        * SILC-specific commands aren't now executed if the active server
          isn't of SILC-type, so there won't be problems with having
          IRC and SILC protocol support in same client. Affected files
          irssi/src/silc/core/silc-channels.c, silc-servers.c,
          silc-commands.h

Wed Mar 20 11:06:57 CET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Improved the signal support in SILC Schedule.  Added new
          function silc_schedule_signal_call which is used by application
          to mark a signal to be called.  It is now safe to perform
          any kind of tasks in signal callbacks since it is guaranteed
          that the application specified signal callback is called
          after the signal is over.  Affected files are
          lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.

Tue Mar 19 20:42:41 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added `name' field to SilcChannelPrivateKey to represent
          application given name for the key.  Moved also the context from
          lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
          Added the `name' argument also to the function
          silc_client_add_channel_private_key.

          Added function silc_client_current_channel_private_key to set the
          current channel private key in use.

          Added "change" command to KEY command which can be used to change
          the current channel private key.  Bound the command also to
          alt+K (Alt+Shift+k).

          Also affected files lib/silcclient/client_channel.c,
          irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.

Tue Mar 19 16:32:43 CET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added silc_rng_get_byte_fast function in to the
          lib/silccrypt/silcrng.[ch].

        * Changed the interface of silc_packet_assemble and the
          silc_packet_send_prepare.  If silc_packet_assmble is now
          called the application does not call silc_packet_send_prepare
          because the library will call it automatically.  These
          interfaces now also return a reference to the outgoing buffer
          which includes the assembled packet, which the application can
          use to encrypt the packet.

          Affected files are lib/silccore/silcpacket.[ch],
          lib/silcclient/client.c, client_channel.c client_prvmsg.c,
          silcd/packet_send.c, server_backup.c and packet_receive.c.

        * Fixed a packet sending bug on very high load, where outgoing
          packet queue wasn't handled correctly and packets got corrupted.
          Affected files are lib/silcutil/*/silc*sockconn.c,
          lib/silcclient/client.c and silcd/server.c.

Mon Mar 18 21:00:41 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added macro SILC_PACKET_DATALEN which can be used during
          packet assembling to check whether the data to be added to
          the packet will fit to SILC_PACKET_MAX_LEN.  If not the data
          len is truncated until it fits it.

          Added checks for maximum length of channel message payload and
          private message payload also.

          Added checks for maximum packet length in server and in
          client library.

          Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
          lib/silcclient/client.c, lib/silccore/silcchannel.c and
          lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
          lib/silcclient/client_prvmsg.c.

Mon Mar 18 14:54:42 CET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added silc_server_packet_queue_purge call to the
          silc_server_disconnect_remote to assure that all data in the
          queue before disconnecting is sent to the network.  Affected
          file silcd/server.c.

Sun Mar 17 19:26:16 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added the deleting of server's own ID cache entry to the
          silc_server_free function.  Free also everything else that
          has been allocated in silc_server_init.  The affected file
          is silcd/server.c.

Sun Mar 17 15:44:56 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added functions silc_parse_version_string, silc_version_to_num,
          and silc_ske_parse_version to parse SILC protocol style version
          strings.  Affected files lib/silcutil/silcutil.[ch] and
          lib/silcske/silcske.[ch].

        * Added new configuration params: version_protocol, version_software
          and version_software_vendor to specify what version the remote
          host must at least be to be able to connect to server.  The vendor
          string can be regex matched too.  Added new function
          silc_server_connection_allowed to check maximum number of allowed
          connections, and allowed versions for incoming connections.
          Affected files are silcd/server.c, server_util.[ch] and
          serverconfig.[ch].

Sun Mar 17 10:24:50 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added preliminary support for signals in scheduler.  The
          signals we care about are now blocked always when the scheduler
          is locked.  This way we can synchronise the use of signal with
          scheduler.  It is guaranteed that when signal occurs the scheduler
          is not locked, and thus new tasks can be safely added to the
          scheduler.

          Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
          to silc_schedule_internal_init and silc_schedule_internal_uninit.
          Added new platform specific routines
          silc_schedule_internal_signals_[un]block and
          silc_schedule_internal_signal_[un]register.

          Added new functions to SILC Schedule API:
          silc_schedule_signal_[un]register.  Each signal that application
          is going to use should be registered to the scheduler.

          Affected files are lib/silcutil/silcschedule.[ch],
          lib/silcutil/*/silc*schedule.c.

Sat Mar 16 22:39:23 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Check for unauthenticated client and server in the
          silc_server_new_client and silc_server_new_server functions.
          Affected file silcd/packet_receive.c.

        * Added function silc_string_is_ascii to check whether given
          string is 7-bit ASCII string.  Affected files are
          lib/silcutil/silcutil.[ch].

        * Added function silc_id_is_valid_server_id into the
          silcd/serverid.c and added checking for valid Server ID's in
          silc_server_new_server.  The Server ID must always be based
          on the server's public IP address.

        * Added logging of DISCONNECT packet message in the server.
          Affected file silcd/server.c.

Sat Mar 16 18:04:30 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Changed all library interfaces that use Global RNG to also
          accept SilcRng as argument.  Affected files are
          lib/silcclient/command.c, lib/silccore/silcauth.[ch],
          lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
          silcd/packet_send.c, lib/silccore/silcprivate.[ch],
          lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
          lib/silccrypt/rsa.c.

        * Added function silc_pkcs_generate_key to the
          lib/silccrypt/silcpkcs.[ch] for applications so that they
          don't need to do pkcs->pkcs->init calls anymore.

        * Remove SilcSocketConnection from the SFTP API since it really
          wasn't needed there.  The application has the information
          saved in its contexts anyway and the SFTP layer doesn't need
          know about it.  Affected files lib/silcsft/silcsftp.h and
          lib/silcsftp/sftp_[server/client].c.

        * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
          The SilcSimContext is not SilcSim.

        * Fixed possible buffer overflows in silc_id_render in the
          lib/silcutil/silcutil.c.

        * On EPOC the global crypto module lists are not used at all
          in the crypto library.  Added support for using the constant
          algorithm list on EPOC.  Affected files are
          lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
          silcpkcs.c.

        * Fixed the handling of third parameter of KICKED notify, since
          it was mistakenly updated to SILC Protocol 1.0 even though it
          is to be included in 1.1.  Since it is not in 1.0 it is not
          mandatory, and this fix now handles it only if it is provided,
          and it is not error if it is not provided.  Affected file
          lib/silcclient/client_notify.c.

Sat Mar 16 09:07:27 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
          client.  Affected file irssi/src/silc/core/client_ops.c.

        * Merged with Irssi 0.8.4 from irssi.org CVS.

Thu Mar 14 12:53:57 CET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Check for valid socket connection in client entries before
          sending any messages.  Fixes a crash, but doesn't fix some
          other underlaying bug that is lurking there.  Affected
          file silcd/packet_send.c.

Thu Mar 14 13:38:12 EET 2002  Timo Sirainen <tss@iki.fi>

        * $usermode, $cumode and $cumode_space expandos shouldn't do
          anything with non-SILC server records. Affected file
          irssi/src/silc/core/silc-expandos.c

Wed Mar 13 21:38:26 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed the silc_net_check_[host/local]_by_sock to support
          IPv6 bound sockets as well.  Now they can return IPv6 addresses
          as well.  Affected file lib/silcutil/silcnet.c.

        * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
          Affected lib/silcutil/unix/silcunixnet.c.

        * Fixed ID rendering (at least on some platforms, not NetBSD)
          for IPv6 addresses.  Affected file lib/silcutil/silcutil.c.

Tue Mar 12 17:58:59 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added silc_hash_public_key and silc_hash_public_key_compare
          functions to be used with SilcHashTable.  They can be used to
          hash public keys and compare public keys in hash table.  Affected
          file lib/silcutil/silcutil.[ch].

        * Added support for specifying multiple public keys for Client
          connection section in server configuration file.  This makes it
          possible to accept multiple public keys from same host, or to
          make a section that accepts any incoming host, and have the
          accepted public keys listed in the section.

          Added functions silc_sever_[find/get]_public_key,  added the
          support for this actually to all connection sections but only
          the Client section is currently allowed to specify multiple
          public keys.

          Affected files are silcd/server.c, server_internal.h,
          command.c, protocol.c, server_util.[ch], packet_receive.c.

Mon Mar 11 23:37:38 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Merged Irssi 0.8.2 from irssi.org CVS.

Sun Mar 10 23:34:48 CET 2002  Johnny Mnemonic <johnny@themnemonic.org>

        * If silc_debug is TRUE, also output standard logging messages
          to stderr with the debug output.

          Made silc_log_reset_all() flushing all channels before returning.
          Also fixed some documentation typos.

          Affected files are lib/silcutil/silclog.[ch].

Sun Mar 10 20:07:49 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed the server to check correctly the amount of connections
          from single host, by checking also the type of the connection.
          Fixed also the comparison of number of connections and number
          of allowed connections.  Affected files are silcd/server.c,
          server_util.[ch].

Fri Mar  8 17:16:41 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed the USERS command reply to save the user's mode on the
          channel as well.  Fixed JOIN command reply to check whether a
          client is on channel already and not join it twice.  Affected
          file lib/silcclient/command_reply.c.

        * Added new file silc-expandos.c into irssi/silc/core/ to return
          various stuff for various signal for the statusbar etc. updating.
          Now Irssi SILC client prints channel user modes etc. on the
          statusbar.

        * The user mode (like server/router operator changes) is now shown
          on the Irssi SILC client's statusbar.  The affected files are
          irssi/src/silc/core/client_ops.c, silc-expandos.c.

Thu Mar  7 19:21:22 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
          to SILC_SCHEDULE_[UN]LOCK macros.

        * Added more error printing to logs in server code.  Affected
          files silcd/server.c and silcd/protocol.c.

        * Fixed -S option parsing in Irssi SILC Client.  Affected file
          irssi/src/silc/core/silc-core.c.

        * Added silc_buffer_alloc_size function.  Affected file is
          lib/silcutil/silcbuffer.h.

Tue Mar  5 14:37:27 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
          constants.  Affected files in
          lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
          silccipher.[ch].

        * Changed the internal SFTP Memory FS table to const.  Affected
          file lib/silcsftp/sftp_fs_memory.c.

Sun Mar  3 18:37:13 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed the buffer formatting and unformatting routines to
          check the size of 64 bits types with sizeof().  Affected
          file is lib/silcutil/silcbuffmt.c.

Mon Feb 25 17:19:05 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Removed 0.6.x backwards support.

Sun Feb 24 12:53:25 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Changed all integer type names:
          [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64].  This is
          to avoid collisions with other libraries using same type names
          as we did.

Sat Feb 23 20:31:43 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added `prefer_ipv6' argument to the functions
          silc_net_gethostbyname[_async].  If it is TRUE it will return
          IPv6 address over IPv4.  If FALSE IPv4 address is returned
          even if IPv6 address was found.  Affected files
          lib/silcutil/silcnet.[ch].

        * Added support silc_net_create_connection[_async] to fallback
          to IPv4 address if IPv6 address could not be used (like if
          it doesn't work on a specific system).  Affected file in
          lib/silcutil/unix/silcunixnet.c.

Sat Feb 23 15:20:30 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added silc_schedule_reinit function to do the enlarging
          of the max tasks handling capabilities of the scheduler.
          Affected files lib/silcutil/silcschedule.[ch].

Wed Feb 20 20:41:01 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added automatic extern "C" { ... } for C++ compilers so the
          application does not need to define them.  Affected file
          includes/silcincludes.h.

        * Renamed lib/silcclient/silcapi.h to silcclient.h as the
          old name went against naming convention.  Applications now
          include "silcclient.h" instead of "clientlibincludes.h".
          Removed includes/clientlibincludes.h, it is redundant now.

        * Renamed includes/version.h to silcversion.h.

        * Added really preliminary support for OS/2 into the util
          library.  Only thread & mutex API is implemented, others
          are still to be implemented.  Created the lib/silcutil/os2/
          directory.  Created also file includes/silcos2.h.

Wed Feb 20 18:48:49 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added preliminary BeOS support into the util library.
          Created lib/silcutil/beos/, and implemented all the needed
          functions to support SILC on BeOS.  Created also file
          includes/silcbeos.h.

Mon Feb 18 15:49:22 EET 2002  Timo Sirainen <tss@iki.fi>

        * Added proper initializations to silc's irssi code, so it's
          now possible to load it as module.  Affected files
          irssi/src/silc/core/silc-core.c,
          fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c

Sun Feb 17 19:02:56 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
          the SILC tree.

        * Fixed the silcdoc document generator to correct generate
          docs from all kinds of filenames.  Affected files are
          util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc

        * ROBOdoc documented lib/silcutil/silcmemory.h.
          Added also new function silc_memdup.

        * Removed lib/silcutil/silcbufutil.h and moved those routines
          to the lib/silcutil/silcbuffer.h.

Sun Feb 17 15:52:30 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added `user_count' to the SilcChannelEntry which now tells the
          number of users on the channel.  The user count is now saved
          in normal server of global channels as well.  Affected files
          silcd/server.c, idlist.h, packet_receive.c and command.c.

        * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
          include file utility functions.

        * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
          instead of calling directly OS routines.

        * Fixed NICK change printing in Irssi SILC Client. Fixed
          KICKED notify printing in Irssi SILC Client.  Affected file
          irssi/src/silc/core/client_ops.c.

        * Fixed a NICK change bug in client library, to not recreate the
          client_entry->channels hash table everytime nick is changed.
          Affected file lib/silcclient/client.c.

Sun Feb 17 10:10:14 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * ROBOdoc documented the lib/silcske/silcske.h, and improved
          the SKE interface a bit.

        * Fixed padding problem in PKCS#1. The padding was not actually
          random since the random number generator was used incorrectly.
          This security bug affects only when encrypting with PKCS#1, and
          it is not currently used at all in SILC. SILC only use signing
          with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

Sat Feb 16 13:44:24 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Rewrote the notify handling in Irssi SILC client to not call
          the events as signals.  Fixes problems with Perl support.
          Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.

        * Send the auto-nicking NICK command in client library with
          little timeout after connecting.  The affected file is
          lib/silcclient/client.c.

        * Added following new config file settings:
          channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
          key_exchange_timeout, conn_auth_timeout, connections_max,
          links_max.

          Implemented all the new config settings handling in the server.

          Optimized the use of SKE Mutual flag usage.  Use it only
          if connection authentication protocol is not based in public
          key authentication.

          Renamed all SilcServerConfigSection* to SilcServerConfig*
          to have a bit shorter names.

          Affected files silcd/serverconfig.[ch], server.[ch], and
          protocol.[ch].

Sat Feb 16 02:46:43 CET 2002  Johnny Mnemonic <johnny@themnemonic.org>

        * Cleaned up the listening sockets code, preparing for the rehash
          support.  Affected file is silcd/server.c.

        * Fixed some output messages.  Affected files are silcd/silcd.c,
          and silcd/server.c.

Fri Feb 15 19:10:20 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Create lib/doc/silcrng_intro.html document as introduction
          to SILC RNG.  ROBOdoc documented lib/silccrypt/silcrng.h.

Fri Feb 15 13:23:03 CET 2002  Johnny Mnemonic <johnny@themnemonic.org>

        * Fixes to the silcd config template.  Affected file is
          doc/example_silcd.conf.in.

        * Removed type casts from silc_calloc(), conforming to the
          CodingStyle.  Affected file is lib/silcutil/silcconfig.c.

        * Removed param_name member from client, server, and router
          section structs, now identifying the param directly.

          Added CONFIG_FREE_AUTH macro in config file parsing.

          Affected files are silcd/serverconfig.[ch].

Fri Feb 15 12:24:08 EET 2002  Timo Sirainen <tss@iki.fi>

        * Fixed command line parameter handling. All SILC initialization
          is now done in silc_core_init() which also fixes autoconnecting
          to servers.

          Affected files irssi/src/silc/core/silc-core.c,
          irssi/src/fe-text/silc.c.

Thu Feb 14 22:03:58 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added new configuration options and blocks:
          keepalive_secs, reconnect_count, reconnect_interval,
          reconnect_interval_max, reconnect_keep_trying and
          require_reverser_lookup.  Added ConnectionParam block, and
          implemented the connection parameters when connecting as
          initiator and when accepting connections as responder.

          Added CONFIG_IS_DOUBLE macro in config file parsing, to check
          whether given configuration value has been given already.

          Affected files silcd/serverconfig.[c], server.[c].

        * Splitted the doc/example_silcd.conf.in.  Separated the crypto
          algorithm parts and created new file silcalgs.conf, that
          is now included from the example_silcd.conf.in.

        * Optimized the silc_server_connect_to_router_second to take
          the connection configuration object from the SilcServerConnection
          object instead of finding it during the connecting phase.
          Added the configuration object to SilcServerConnection struct.
          Affected files silcd/server_internal.h, server.c.

Thu Feb 14 16:02:26 CET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Add the client on channel after it was resolved at the
          channel message receiving, and it was not already on the
          channel.  Affected file lib/silcclient/client_channel.c.

Wed Feb 13 23:16:41 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed the public key authentication to allocate always the
          destination signature buffer instead of using static buffer.
          Affected file silcd/protocol.c.

Wed Feb 13 20:51:13 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Unified the serverconfig.[ch]'s helper function interface.
          Affected file silcd/serverconfig.[ch].

        * Removed doc/example_silc.conf.in since it is redundant.
          The make install will now install irssi/silc.conf file.

        * Added new Passphrase and Publickey authentication methods to
          config file, allowing both public key and passphrase based
          authentication to be set at the same time.

          Added `prefer_passphrase_auth' setting in config file which
          can be used to set to prefer passwd auth if both passwd and
          public key is set.  If not set, public key is preferred.
          This has effect only when being initiator (responder will try
          both anyway).

          Added support for authentication with passphrase and public key
          at the same time.  The passphrase is tried first always since
          it is faster to check.

          Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].

Wed Feb 13 12:46:25 CET 2002  Johnny Mnemonic <johnny@themnemonic.org>

        * Merged the new SILC Config library, with the server parsing
          support.  Read the header file silcconfig.h or the toolkit

          silcd/serverconfig.[ch] silcd/silcd.c.

        * Fixed some silclog documentation.  Affected file is
          lib/silcutil/silclog.h.

Sun Feb 10 18:11:30 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * The silc_cipher_register, silc_hash_register and
          silc_hmac_register now checks if the object to be registered
          is registered already.  Affected files are
          lib/silccrypt/silccipher.c, silchash.c and silchmac.c.

Sun Feb 10 15:48:38 EET 2002  Pekka Riikonen <priikone@silcnet.org>

          Payload.  Affected file lib/silccore/silcchannel.c.

        * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
          as header filenames.

        * Removed lib/silcclient/README and created HTML file
          lib/silcclient/silcclient_using.html, which is now included
          as part of Toolkit documentation.

Thu Feb  7 10:12:25 CET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed CUMODE_CHANGE notify handling to change the mode of
          correct client.  Affected file lib/silcclient/client_notify.c.

        * Make silc_rng_alloc fail if it cannot allocate the sha1
          hash algorithm.  Affected file lib/silccrypt/silcrng.c.

Sun Feb  3 17:20:52 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed the file transfer's key agreement payload to include
          zero port also if the hostname is NULL because it could not
          be bound.

          Call file transfer monitor callback now also if error occurs
          during key agreement protocol.

          Changed the silc_client_file_send interface to return the
          SilcClientFileError instead of session id.  The session ID
          is returned into pointer provided as argument.

          Check that the file exists locally before sending the
          file transfer request at all.

          Affected file lib/silcclient/client_ftp.c, silcapi.h.

        * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
          error than can occur while key agreement protocol.  Affected
          file lib/silcclient/silcapi.h.

        * Fixed the event_mode CMODE handler to not crash when mode
          is changed and +k mode is set in the channel.  Affected file
          irssi/src/silc/core/silc-channels.c.

        * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
          SILC_LOG_WARNING to give out Warning and not Error.  Affected
          file lib/silcutil/silclog.c.

        * Fixed the channel message payload decryption in the function
          silc_channel_message_payload_decrypt to not modify the original
          buffer before it is verified that the message decrypted
          correctly.  Otherwise, next time it is called with correct
          channel key it won't encrypt since the payload is corrupted.
          Affected file lib/silccore/silcchannel.c.

Sun Feb  3 11:46:12 EET 2002  Pekka Riikonen <priikone@silcnet.org>

          Affected file lib/silcutil/silcnet.c.

Fri Feb  1 22:33:11 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed a bug in hash table internal routine for traversing
          the table with foreach callback.  The current entry may
          become invalid in the callback but it was referenced after
          the callback returned.

          Do not allow auto rehashing of hash table during the
          silc_hash_table_foreach operation, for same reasons as it is
          not allowed for SilcHashTableList.  Affected files are
          lib/silcutil/silchashtable.[ch].

Fri Feb  1 14:55:00 CET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Defined DLLAPI into silcincludes.h and silcwin32.h for
          Win32 DLL.  extern's in header files are now declared with
          DLLAPI.

Thu Jan 31 23:34:33 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed private message handling.  It used some old code that
          caused the client to crash.  Affecte file is
          lib/silcclient/client_prvmsg.c.

Thu Jan 31 19:06:22 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added function silc_client_add_channel,
          silc_client_replace_channel_id, and removed functions
          silc_client_new_channel_id and silc_idlist_get_channel_by_id
          from client library.

        * Added cross reference of the joined channels to the
          SilcClientEntry, and changed the SilcChannelEntry's
          users list to SilcHashTable.  The affected files are
          lib/silcclient/idlist.[ch].

        * Fixed a bug in hash table tarversing.  While the hash table
          is traversed with SilcHashTableList the table must not be
          rehashed.  It is now guaranteed that auto rehashable tables
          are not rehashed while tarversing the list.  Also defined that
          silc_hash_table_rehash must not be called while tarversing
          the table.  Added function silc_hash_table_list_reset that must
          be called after the tarversing is over.  The affected files are
          lib/silcutil/silchashtable.[ch].

        * Changed all hash table traversing to call the new
          silc_hash_table_list_reset in server and in client library.

        * Added function silc_client_on_channel to return the
          SilcChannelUser entry if the specified client entry is joined
          on the specified channel.  This is exported to application as
          well.  Affected files lib/silcclient/client_channel.c, silcapi.h.

Wed Jan 30 19:14:31 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed founder regaining problem with JOIN command on normal
          server.  The notify for mode change must be sent always and
          not only if !cmd->pending.  Affected file silcd/command.c.

        * Fixed the WHOWAS command's reply sending to support the
          lists correctly.  Affected file silcd/command.c.

Wed Jan 30 11:11:47 CET 2002  Pekka Riikonen <priikone@silcnet.org>

        * When sending JOIN command to router for processing the
          sender's old command identifier was not saved back to the
          sender's command context, fixed now.  The affected file is
          silcd/command.c.

        * Create the key in JOIN command of the router did not return
          the channel key, added check for this.  Affected file is
          silcd/command.c.

        * Fixed a channel ID update bug in JOIN command reply.  Do
          not directly upgrade the ID but call the function
          silc_idlist_replace_channel_id if the ID was changed.
          Affected file silcd/command_reply.c.

        * Fixed memory leaks from command calling if it would fail.
          Affected file silcd/command.c.

Tue Jan 29 19:49:31 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Applied patches from cras:

          Memory leak fixes around libaries, irssi window resize fix,
          new silclist.h and silcdlist.h, all extern inline changed to
          static inline.

        * Removed dotconf from lib/dotconf, not needed anymore.

        * Removed TRQ from lib/trq, not needed anymore.

        * Do more frequent heartbeats (5 minutes instead of 10 minutes)
          with server connections.  Later this will be configurable
          in config file after new config file is done.  Affected file
          silcd/server.c.

Tue Jan 29 10:35:03 CET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed a crash in server related to channel announcements.
          Affected file silcd/server.c.

Mon Jan 28 17:49:42 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed memory leaks in silc_server_create_new_channel*
          functions.  Affected file silcd/server.c.

        * Fixed the CHANNEL_CHANGE notify to re-announce the channel
          which ID was changed.  This way the router will send the
          user list for the channel again, and server won't be in
          desync in some rare circumstances.  Affected file is
          silcd/packet_receive.c.

Sun Jan 27 21:04:19 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Check for NULL socket pointer in the function
          silc_server_packet_send_to_channel_real.  Affected file
          silcd/packet_send.c.

        * Fixed the BAN notify handling to correctly remove ban
          list.  Affected file silcd/packet_receive.c.

Sat Jan 26 23:01:03 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed some header addition to Toolkit distribution in
          lib/silcutil/Makefile.am and lib/trq/Makefile.am.

        * Added lib/silcclient/client_ops_example.h as an template
          file for application programmers to quickly start using
          the SilcClientOperation functions in their application.
          Updated the lib/silcclient/README as well to tell about this
          nice file made available.

Sat Jan 26 10:45:41 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Call silc_server_remove_from_channels when removing client
          entry when NO_SUCH_CLIENT_ID was received.  Affected file
          is silcd/command_reply.c.

Fri Jan 25 19:12:36 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added server & router operator statistics updating.  Affected
          file silcd/packet_receive.c and silcd/command.c.

        * Fixed the SERVER_SIGNOFF notify handling on normal server
          not to save the history information for clients.  Same was
          fixed earlier in remove_clients_by_server function, but not
          here.  Affected file silcd/packet_receive.c.

        * Raised the default connection-retry count from 4 to 7 in
          server.  Affected file silcd/server.h.

        * Cancel any possible reconnect timeouts when we start the
          key exchange.  Affected file silcd/server.c.

        * Do not reconnect on connection failure when SCONNECT was
          given.  Affected files silcd/server.[ch].

Tue Jan 22 18:19:36 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Removed assert()'s from the lib/silcclient/client_keyagr.c.

        * Fixed the NICK command to always give the unformatted
          nickname to the one giving the NICK command.  If unformatted
          nickname is cached already it will be formatted and the
          local entry will always get the unformatted nickname.
          Affected file lib/silcclient/idlist.c.

        * Fixed some double frees from client library commands.
          Affected file is lib/silcclient/command.c.

        * Fixed CUMODE command in server to assure that no one can
          change founder's mode than the founder itself, there was a
          little bug.  Affected file silcd/command.c.

Mon Jan 21 19:07:53 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Removed the SilcClientCommandDestructor from the client
          libary, it is not needed anymore.  Affected files are
          lib/silcclient/silcapi.h, command[_reply].[ch],
          client_notify, idlist.c.

        * Fixed GETKEY command to first resolve client, and then
          resolve the server only if the client was not found, instead
          of resolving both at the same time.  Affected file is
          lib/silcclient/command.c.

        * Added silc_client_start_key_exchange_cb and lookup the
          remote hostname and IP address before starting the key
          exchange with server.  The affected file is
          lib/silcclient/client.c.

        * The server's public key is now saved using the IP address
          of the server and not the servername for the filename.
          The hostname public key filename is checked as an fall back
          method if the IP address based filename is not found.

          Fixed the GETKEY command to save the fetched server key
          in correct filename.

          Print the remote server's hostname now when new key is
          received during connection process.  Affected file is
          irssi/src/silc/core/client_ops.c.

        * Return always our own public key to the client if it asks
          for it with GETKEY command.  Affected file silcd/command.c.

        * Removed the use_auto_addr variable from default config
          file since it was in wrong section.  Affected file is
          irssi/src/config.

        * Fixed TOPIC_CHANGE notification to not route it when it
          was sent using silc_server_send_notify_to_channel function.
          Affected file silcd/command.c.

        * Fixed silc_server_send_notify_kicked to send the kicker's
          Client ID also, it was missing.  Affected files are
          silcd/command.c, silcd/packet_send.[ch].

Thu Jan 17 18:59:11 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Do not save client history information in SERVER_SIGNOFF.
          Fixes the bug in normal server that it does not detect
          the client becoming valid after the server becomes back
          online.  Affected file silcd/server_util.c.

        * Added `sock_error' field  into the SilcSocketConnection
          context.  When error occurs during socket operation (read
          or write) the error is saved.  Added also new function
          silc_socket_get_error to return human readable socket error
          message.  Affected files are lib/silcutil/silcsockconn.[ch],
          lib/silcutil/unix/silcunixsockconn.c, and
          lib/silcutil/win32/silcwin32sockconn.c.

        * The server now prints the socket error message in the
          signoff for client.  Affected file silcd/server.c.

        * Fixed the `created' channel information sending from router
          to server in JOIN command.  Checks now whether the channel
          really was created or not and set it according that.

          Fixed the JOIN command to use the client entry's current
          ID during the joining procedure instead of the one it sent
          in the command (it is checked though), since it can change
          between the packet processing and command processing, and
          would just case unnecessary pain in the client end.  Affected
          file silcd/command.c.

        * Fixed a channel key payload sending to use correct channel
          ID when the server was forced to change the channel's ID by
          router.  Router sent the key payload with the old Channel ID.
          Affected file silcd/packet_receive.c.

Wed Jan 16 22:26:30 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Call silc_server_save_channel_key only if the key payload
          was provided in the JOIN command's command reply.  Affected
          file silcd/command_reply.c.

Tue Jan 15 18:49:41 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed silc_mp_sizeinbase to return the value correctly with
          MPI.  Affected file lib/silcmath/mp_mpi.c.

        * Fixed the stop_server signal to correctly stop the scheduler
          and gracefully stop the server when SIGTERM or SIGINT signals
          are received.  Affected file silcd/silcd.c.

Mon Jan  7 23:38:19 CET 2002  Johnny Mnemonic <johnny@themnemonic.org>

        * Simple handling of TERM and HUP signals. Also added some log
          flushing call around.  Affected file is
          silcd/silcd.c.

        * Fixed small bugs in silclog.c. Now buffering output will take
          effect after 10 seconds since startup: This will ensure that
          no important startup messages are lost. Also output redirection
          will preserve original format ([Date] [Type] message).
          Affected file is lib/silcutil/silclog.c.

        * Added two options to the config file, in the logging section:
          quicklogs:<yes/no>: and flushdelay:<seconds>:.  Affected files
          lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].

Sun Jan  6 12:49:40 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Do not print the warning about log files not being initialized
          more than once to avoid excess logging.  Affected file is
          lib/silcutil/silclog.c.

        * Fixed the SIM compilation in lib/silcsim/Makefile.am.  Fixed
          the SIM copying in make install in Makefile.am.pre.

Sun Jan  6 01:10:21 CET 2001  Johnny Mnemonic <johnny@themnemonic.org>

        * Rewritten silclog APIs. Globally interesting changes follows:
          silc_log_set_files() changed to silc_log_set_file().
          silc_log_set_callbacks() changed to silc_log_set_callback().
          ROBOdoc documented silclog header file.
          SilcLogCb now returns bool to wether inihibit the default
          handler or not (to keep the old behaviour return always TRUE).
          The new APIs should also fix the problem of the
          silcd_error.log file that was written in the current directory.

          New features:
          Log files streams will remain opened after silc_log_set_file()
          call, means less CPU usage notably on high traffic servers.
          File streams are now full buffered, and flushed to the disk
          every 5 minutes, lesses HD activity and CPU usage.
          Messages can be redirected, allowing admins to configure
          one single logfile for all server messages.
          the silc_log_quick global variable to activate fast-logging.
          Affected files lib/silcutil/silclog.[ch]

        * Changed some code to conform new silclog APIs. Affected
          files are doc/example_silcd.conf.in, silcd/server.c
          irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
          silcd/silcd.c.

        * Fixed a memory leak that could occur in some situations.
          Affected file silcd/serverconfig.c.

Sat Jan  5 13:37:29 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Added the silc_client_del_client to remove the client from
          all channels as well.  Affected file lib/silcclient/idlist.c.

        * Fixed the client library to correctly remove the client
          from all channels when the client entry is being destroyed.
          Affected file lib/silcclient/client_notify.c, command.c.

        * Added auto-nicking support to the client library.  If the
          applicatio now sets client->nickname it will be sent to the
          server after connecting by the library.  This way for example
          SILCNICK (or IRCNICK) environment variables will have effect
          and always change the nickname automatically to whatever
          it is wanted.  Affected file lib/silcclient/client.[ch].

        * Renamed silc_server_command_bad_chars to the
          silc_server_name_bad_chars and moved it to the
          silcd/server_util.[ch].  Added also new function
          silc_server_name_modify_bad to return nickname that
          includes bad characters as new nickname without those
          bad characters.  This check and modify is now used in
          silc_server_new_client when the username is initially set
          as nickname, so it must be checked to be valid nickname.
          Affected file silcd/packet_receive.c.

        * The nickname length is now taken from the packet for real
          and not trusted to strlen() since it clearly can return
          wrong length for nickname including bad characters.  This
          also applies to channel names.  Affected file silcd/command.c.

        * Removed the lib/silcsilm/modules directory.  Modules are now
          compiled into the lib/silcsim.  Fixed the copying of the
          modules to follow symbolic links in Makefile.am.pre.

Wed Jan  2 18:56:21 EET 2002  Pekka Riikonen <priikone@silcnet.org>

        * Fixed silc_string_regexify list creation.  Fixes bugs with
          BAN and INVITE commands in server.  The affected file is
          lib/silcutil/unix/silcunixutil.c.

Sun Dec 30 13:41:34 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Removed the command destructor entirely from the server's
          command and command reply routines.  It is not needed, and
          its usage was buggy and caused crashes.  Affected files are
          silcd/command[_reply].[ch].

Fri Dec 28 12:43:22 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Cancel protocol and NULL sock->protocol if timeout
          occurred during protocol.  Affected file silcd/server.c.

        * Cancel protocol timeouts always before calling the final
          callback, to assure that after final callback is called
          no other state will be called for the protocol anymore.
          Affected file silcd/protocol.c.

        * Print error log if incoming connection configuration could
          not be found.  Affected file silcd/server.c.

        * Fixed JOIN command to correctly save the founder mode
          to the client on normal SILC server, when the channel
          was created by the router.  Affected file silcd/command.c.

        * Fixed LIST command (hopefully) to send correct reply
          packets.  Affected file silcd/command.c.

Thu Dec 20 16:14:52 CET 2001  Pekka Riikonen <priikone@silcnet.org>

        * The silc_packet_receive_process now returns FALSE if the
          read data was invalid packet, and TRUE if it was ok.

          The server now checks that if unauthenticated connection
          sends data and its processing fails the server will close
          the connection since it could be a malicious flooder.

          Affected files lib/silccore/silcpacket.[ch], silcd/server.c.

Wed Dec 19 21:31:25 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Make sure the warning about error opening a log file is
          printed only once and not everytime it fails (produces
          too much useless log).  Affected file lib/silcutil/silclog.c.

Wed Dec 19 18:21:51 CET 2001  Johnny Mnemonic <johnny@themnemonic.org>

        * Made the silc_server_daemonise() function more readable.
          Affected file silcd/server.c.

        * Pid file is now optional, the user may comment it out from
          the config file. Removed define SILC_SERVER_PID_FILE, we
          don't need a default any longer.  Affected file
          configure.in.pre, lib/Makefile.am.pre.

        * Make some use of the pid file. The server now dies at startup
          if it detects a valid pid file on his path. The server would
          die anyway in this circumstance, because of the bind() failure.
          Affected file silcd/silcd.c.

        * No longer compiling lib/dotconf.

Mon Dec 17 18:24:27 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed JOIN command parsing not to crash.  Affected file
          lib/silcclient/command.c.

        * Fied the NICK_CHANGE notify to add the new client entry
          even it is resolved.  This removes an <[unknown]> nick
          thingy bug in the client.  Affected file is
          lib/silcclient/client_notify.c.

        * Do not try to allocate 0 bytes (efence does not like it)
          in lib/silccore/silccomand.c when encoding payload.

        * Do not take IRCNICK as nickname in Irssi SILC client since
          it is not possible to set nickname before hand connecting
          the server (TODO has an entry about adding auto-nicking
          support).

        * Changed the silc_server_command_pending to check whether
          there already exists an pending entry with the specified
          command, command identifier and pending callback.  This is
          to fix IDENTIFY and WHOIS related crashes that may register
          multiple pending commands with same identifier.  Affected
          file silcd/command.c.

        * Fixed the server to reconnect to the router even if it
          was already reconnecting and EOF was received.  This to
          fix a possibility that the server wouldn't ever try to
          auto-reconnect to the router.  Affected file silcd/server.c.

Sat Dec 15 20:31:50 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed the server's password authentication to use the
          length of the locally saved password, and not the one
          sent in the packet.  Affected file silcd/protocol.c.

        * Fixed same password authentication problem in the
          Authentication Payload handling routines in
          lib/silccore/silcauth.c.

        * Yet another password authentication problem fixed with
          channel password handling in silcd/command.c.

Mon Dec 10 19:57:40 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * If first character of string in silc_parse_userfqdn is '@'
          then do not parse it.  Affected file is
          lib/silcutil/silcutil.c.

Sun Dec  9 22:18:50 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed minor bug in IDENTIFY command reply sending, which
          caused various weird problems during JOIN when it was
          resolving names for users.  Affected file silcd/command.c.

Sun Dec  9 19:18:41 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed the IDENTIFY command reply sending to chech better valid
          clients.  It was possible to send incomplete list of replies.
          Affected file silcd/command.c.

Sat Dec  8 15:58:31 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added silc_client_command[s]_[un]register functions now to
          dynamically register the commands in client library.  Removed
          the static table of commands.  This allows the client library
          to call commands without causing the application to know about
          what commands library has called.

          Removed the INFO command reply kludge to detect when the command
          was called by library.  Now library use its own command reply
          function for INFO command.

          Added function silc_client_command_call to call a command.
          Application can use it to call command, not access the structure
          directly.

          Now all commands that are sent by the client library (not
          explicitly sent by application) use own command reply functions.

          Affected files around lib/silcclient/ and in
          irssi/src/silc/core/.

        * Fixed the WHOIS command reply sending to chech better valid
          clients.  It was possible to send incomplete list of replies.

          Fixed the WHOIS and IDENTIFY to send the request to router
          if normal server did not do it and did not find any results.

          Affected file silcd/command.c.

Thu Dec  6 17:21:06 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Moved the internal data from SilcClient context into its
          own file, not accesible to application.  Affected files
          lib/silcclient/client.h and lib/silcclient/client_internal.h,
          and other files in client library.

Thu Dec  6 10:37:55 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added doc/examples installation target in Makefile.am.pre.
          A patch by salo.

Tue Dec  4 17:43:19 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
          commands the found client entry will be removed from the
          cache, after notifying application about the error.  Affected
          file lib/silcclient/command_reply.c.

        * Changed the /MSG to check for exact nickname user gave, and
          not let `nick' match `nick@host' if it is only one found.  Now,
          user must type the exact nickname (like nick@host2) even if
          there are no more than one same nicks found.  This is to avoid
          a possibility of sending nickname to wrong nickname since
          `nick' could match `nick@host'.  Affected file is
          irssi/src/core/silc-servers.c.

Mon Dec  3 18:49:45 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Do not print "you are now server operator" or similar when
          giving /away command.  Affected files are
          irssi/src/silc/core/client_ops.c, silc-servers.h.

        * Made the silc_server_command_pending_error_check to send
          the same command reply payload it received back to the
          original sender of the command.  This way all arguments
          that was received by the server will be received by the
          client too.  Affected file silcd/command.c.

        * Added the silc_idcache_add to return the created cache entry
          to a pointer.  Affected file lib/silccore/silcidcache.[ch].

        * Add global clients to expire if they are not on any channel.
          This is because normal server will never know if they signoff
          if they are not on any channel.  The cache expiry will take
          case of these entries.  This is done by normal servers only.
          The affected files are silcd/command_reply.c,
          silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.

        * If server receives invalid ID notification for WHOIS or
          IDENTIFY and the ID exists in the lists, it is removed.
          Affected file silcd/command_reply.c.

        * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
          in client then client entry that it matches is searched and
          the nickname is printed on the screen for user.  Affected
          file irssi/src/silc/core/client_ops.c.

Mon Dec  3 11:56:59 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Use cache entry expire time in the LIST command reply to
          purge old entries from the cache after the LIST command
          reply has been received.  This way we don't have non-existent
          entries in the cache for too long.  Affected file is
          silcd/command_reply.c.

Sun Dec  2 23:29:07 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * If we are normal server, and we've not resolved client info
          in WHOIS or IDENTIFY from router, and it is global client,
          we'll check whether it is on some channel.  If it is not
          then we cannot be sure about its validity and will resolve it
          from router.  Fixes a bug in WHOIS and IDENTIFY.  Affected
          file silcd/command.c.

        * Search channel by name (if possible) rather than by ID
          in IDENTIFY command's command reply.  Affected file is
          silcd/command_reply.c.

Sun Dec  2 13:48:46 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Distribute to the channel passphrase in CMODE_CHANGE notify.
          Updated specs and implemented it.  Affected file silcd/command.c,
          silcd/packet_send.c and silcd/packet_receive.c.

        * Implemented the <founder auth> payload handling in the JOIN
          command.  If provided all conditions for channel joining
          except requirement to provide correct passphrase can be
          overrided by the channel founder.  Updated the protocol specs.
          Affected file silcd/command.c.

          Added support for founder auth in JOIN command in client
          library.  Fixed the parsing of the JOIN command now to support
          all options as they should be.  The affected file is
          lib/silcclient/command.c.

        * Optimized the WHOIS and IDENTIFY commands to send the request
          to router only if it includes nicknames or other names.  If
          they include only IDs then check the local cache first before
          routing.  Affected file is silcd/command.c.

        * Added channels topic announcements.  Affected file is
          silcd/packet_receive.c and silcd/server.c.

        * Fixed the silc_server_send_notify_topic_set to really destine
          the packet to channel.  Affected file silcd/packet_send.c.

        * Fixed a crash in CHANNEL_CHANGE notify handling in the client
          library.  Affected file lib/silcclient/client_notify.c.

        * Added UMODE announcements.  Affected file silcd/server.c.

Sat Dec  1 12:52:39 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Memory leak fixes in:

          lib/silcutil/silcsockconn.c
          lib/silcske/silcske.c
          lib/silcske/groups.c
          lib/silccrypt/rsa.c
          lib/silccrypt/silcpkcs.c
          lib/silccore/silccommand.c
          lib/silccore/silcidcache.c
          silcd/idlist.c
          silcd/packet_send.c
          silcd/command.c

        * ROBOdoc documented the lib/silcske/groups.h file and a
          bit changed the interface for better.

Thu Nov 29 22:12:50 EET 2001  Pekka Riikonen <priikone@silcnet.org>'

        * Update the client entry context in the ID cache after
          nick change.  Affected file lib/silcclient/command.c.
          Fixes the CUMODE command when regaining founder privileges,
          and a little WHOIS problem.

        * Fixed silc_net_gethostbyname to correctly call the
          inet_ntop.  Affected file lib/silcutil/silcnet.c.

Thu Nov 29 19:31:23 EET 2001  Pekka Riikonen <priikone@silcnet.org>'

        * Added IPv6 support checking to the configure.in.pre, added
          also --enable-ipv6 option to override the check.  Affected
          file configure.in.pre.

        * The silc_thread_create now calls the start function
          directly if threads support is not compiled in.  Removes
          ugly #ifdef's from generic code.  Affected files are
          lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.

        * Added silc_net_gethostby[name/addr]_async to asynchronously
          resolve.  Affected files are lib/silcutil/silcnet.[ch].

        * Added support for rendering IPv6 based server, client and
          channel IDs.  Affected file lib/silcutil/silcutil.c.

        * Added support for creating IPv6 based server IDs.  Affected
          file is silcd/serverid.c.

Wed Nov 28 23:46:09 EET 2001  Pekka Riikonen <priikone@silcnet.org>'

        * Added silc_net_gethostby[addr/name] into the
          lib/silcutil/silcnet.[ch].  Added IPv6 support to Unix network
          routines.  Added silc_net_is_ip[4/6].  Affected file is
          lib/silcutil/unix/silcunixnet.c.  All routines that take
          address as argument now supports both IPv4 and IPv6 addresses.

Mon Nov 26 18:09:48 EET 2001  Pekka Riikonen <priikone@silcnet.org>'

        * Fixed LIST command reply sending in server.  Affected file
          silcd/command.c.

        * Server now sends the kicker's client ID in the KICK notify
          to the kicked client.  Affected file silcd/command.c.

        * The client library now parses the kickers client ID and
          UI displays it.  Affected files lib/silcclient/client_notify.c
          and irssi/src/silc/core/silc-channels.c, module-formats.c.

        * Made all payload parsing function prototypes consistent.
          They all take now const unsigned char * and uint32 pair as
          the payload data instead of SilcBuffer.  Changes all around
          the source tree.  Other unsigned char* -> const unsigned char*
          changes around the tree as well.

        * Optimized SFTP client and server packet sending not to
          allocate new buffer for each packet but to recycle the
          first allocated buffer.  Affected files are
          lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].

        * Optimized the SFTP client to use SilcList instead of
          SilcDList for requests, because it is faster.  Affected file
          is lib/silcsftp/sftp_client.c.

        * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
          into lib/silccore/silcid.[ch].

          Renamed silcpayload.[ch] into silcargument.[ch].

Mon Nov 26 15:01:53 CET 2001  Pekka Riikonen <priikone@silcnet.org>

        * If client entry is deleted with active key agreement
          session, abort the session.

          The silc_client_abort_key_agreement now calls the completion
          callback with new SILC_KEY_AGREEMENT_ABORTED status.

          Affected file lib/silcclient/silcapi.h, client_keyagr.c and
          idlist.c.

Sun Nov 25 18:01:45 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Don't use __restrict in older GCC's.  Affected file is
          lib/silcmath/mpi/mpi-priv.h.  A patch by salo.

        * silc_net_localhost now attempts to reverse lookup the
          IP/hostname.  Affected file lib/silcutil/silcnet.c.

        * Defined <founder auth> argument to the SILC_COMMAND_JOIN
          command.  It can be used to gain founder privileges at
          the same time when joining the channel.

          Defined that the SILC_NOTIFY_TYPE_KICKED send the
          kicker's client ID as well.  Updated protocol specs.

          Defined that the server must send SILC_COMMAND_IDENTIFY
          command reply with error status to client who sent
          private message with invalid client ID.

          Updated the protocol specification.

        * Added silc_server_send_command_reply to send any
          command reply.  Affected file silcd/packet_send.[ch].

        * Added silc_id_payload_encode_data to encode ID payload
          from raw ID data.  Affected file lib/silccore/silcpayload.[ch].

        * The server now send IDENTIFY command reply with error
          status if client ID in private message is invalid.  Affected
          file silcd/packet_receive.c.

        * Save the server key file with server's IP address in
          the filename instead of hostname.  The affected file is
          irssi/src/silc/core/client_ops.c.

Sat Nov 24 20:08:22 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
          A patch by Sunfall.

        * Added libtool support for compiling shared objects in
          lib/silcsim.  Affected file configure.in.pre and
          lib/silcsim/Makefile.am.  Original patch by cras.

Fri Nov 23 23:30:59 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Pid file configuration, and server's config file fixes
          patch by toma.  Updated CREDITS file.

Sun Nov 18 01:34:41 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed silc_client_channel_message to not try to decrypt
          the message twice if it resolved the destination client
          information.  This could cause of dropping one channel
          message.  Affected file lib/silcclient/client_channel.c.

Wed Nov 14 23:44:56 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added silc_client_run_one into lib/silcclient/silcapi.h and
          lib/silcclient/client.c. This function is used when the SILC
          Client is run under some other scheduler, or event loop or
          main loop.  On GUI applications, for example this may be
          desired to used to run the client under the GUI application's
          main loop.  Typically the GUI application would register an
          idle task that calls this function multiple times in a second
          to quickly process the SILC specific data.

Wed Nov 14 19:16:52 CET 2001  Johnny Mnemonic <johnny@themnemonic.org>

        * Fixed silc_server_drop() for dropping the supplementary
          groups as well, this could cause a security hole on some
          systems.

Wed Nov 14 16:22:25 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * __pid_t -> pid_t in lib/silccrypt/silcrng.c.  A patch by
          johnny.

        * Write PID file after dropping privileges.  Added -F option
          to run server on foreground.  A patch by debolaz.
          Affected files silcd/server.c, silcd/silcd.c.

        * Fixed MOTD to return the MOTD file server name.  Affected
          file silcd/command.c.

        * Added INFO command reply handling to the Irssi SILC Client.
          Affected file irssi/src/silc/core/client_ops.c.

Wed Nov 14 00:18:08 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed the silc_idcache_list_* routines to really support
          the dynamic list.  Fixes a crash.  Affected file is
          lib/silccore/silcidcache.c.

        * Fixed the LIST command reply to really call LIST command's
          pending callbacks.  Affected file silcd/command_reply.c.

Tue Nov 13 00:49:17 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Update conn->local_entry->nickname after giving NICK
          command.  Affected file lib/silcclient/command.c.

Sun Nov 11 23:43:02 PST 2001  Brian Costello <bc@wpfr.org>

        * Added the [pid] option to the silcd configuration file

          Affected files: serverconfig.[ch] and silcd.c

Sun Nov 11 23:56:39 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Save fingerprint in WHOIS command reply in server.
          Affected file silcd/command_reply.c.

        * Fixed NICK commands pending callback registration.
          Affected file lib/silcclient/command.c.

Sun Nov 11 10:49:10 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Use ++server->cmd_ident when sending commands in server,
          instead of random number.  Affected file silcd/command.c.

        * Fixed GETKEY command reply to call actually GETKEY pending
          command callbacks.  Affected file silcd/command_reply.c.

        * A bit stricter check for nicknames.  Check for same nickname
          in NICK command also.  Affected file silcd/command.c.

        * Do not call INFO command everytime client ID changes, only
          during first connecting.  Affected file lib/silcclient/client.c.

        * Set the new nickname only after successful command reply for
          NICK command is returned by server.  Affected file
          lib/silcclient/command.c.

        * Remove nicknames from nicklist during server_signoff notify.
          Should fix /NAMES bit more.  The affected file is
          irssi/src/silc/core/silc-channels.c.

        * Added `fingerprint' field to the SilcIDListData in the
          silcd/idlist.h to hold the fingerprint of the client's
          public key.

          Send the fingerprint of the client's public key in WHOIS
          command reply.

          Affected files silcd/command.c, and silcd/idlist.[ch].

        * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
          create fingerprint from given data.

        * Show the fingerprint of the client's public key in WHOIS.
          Affected files irssi/src/module-formats.[ch] and
          irssi/src/silc/core/client_ops.c.

        * Format the multiple same nicknames also during JOIN and
          NICK_CHANGE notifys.  Affected file is
          lib/silcclient/client_notify.c.

        * Do not print error on screen for invalid private message
          payload since it can come if someone is sending private
          messages with wrong key.  Affected file
          lib/silccore/silcprivate.c.

        * Fixed multiple concurrent /PING crash.  Affected file
          lib/silcclient/command.c.

        * Changed the wrong ID encoding.  All IP addresses must be
          in MSB first order in encoded format.  They were encoded
          wrong and was in LSB format.  Affected files are
          silcd/serverid.c, lib/silcutil/silcutil.c.

        * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].

        * Call the `connect' client operation through the scheduler
          in case of error.  Affected file lib/silcclient/client.c.

        * Call the `failure' client operation even if the error
          occurred locally during a protocol.  Affected file is
          lib/silcclient/protocol.c.

        * Added support of sending LIST command to router from normal
          server.  This way normal server can get list of all channels
          in the network too.  Fixed the channel list sending in the
          server too.  Affected files are silcd/command.c, and
          silcd/command_reply.[ch].

        * Added silc_server_update_channels_by_server and
          silc_server_remove_channels_by_server.  They are used during
          disconnection of primary router and in backup router protocol.
          Affected file silcd/server_util.[ch], silcd/server.c and
          silcd/server_backup.c.

        * Fixed channel adding to global list in IDENTIFY command
          reply in server.  Affected file silcd/command_reply.c.

Sat Nov 10 21:39:22 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * If the incoming packet type is REKEY or REKEY_DONE process
          that packet always synchronously.  Fixes yet another MAC
          failed error on slow (dialup) connections.  Affected file
          lib/silcclient/client.c and silcd/server.c.

Thu Nov  8 22:21:09 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Call check_version SKE callback for initiator too.  Affected
          file lib/silcske/silcske.c.

        * Implemented fix for security hole found in the SKE that was
          fixed in the specification few days back; the initiator's
          public key is now added to the HASH value computation.
          Added backwards support for the old way of doing it too, for
          old clients and old servers.  Affected file is
          lib/silcske/silcske.c.

        * Enabled mutual authentication by default in SKE.  If initiator
          is not providing mutual authentication the responder will
          force it.  This will provide the proof of posession of the
          private key for responder.  The affected files are
          lib/silcclient/protocol.c and silcd/protocol.c.

        * Do not cache anymore the server's public key during SKE.
          We do mutual authentication so the proof of posession of
          private key is done, and if the server is authenticated in
          conn auth protocol with public key we must have the public
          key already.  Affected file silcd/protocol.c.

        * Added new global debug variable: silc_debug_hexdump.  If
          it is set to TRUE SILC_LOG_HEXDUMP will be printed.  Affected
          file lib/silcutil/silclog.[ch].

        * Fixed compilation warning due to char * -> const char *.
          Affected files lib/silcutil/silcnet.h, and
          lib/silccore/silcauth.[ch].

Wed Nov  7 20:43:03 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed CMODE command when new channel key was created.  If
          the creation failed the old key was removed.  Next time giving
          same command would crash the server since the old key was
          freed already.  Affected file silcd/command.c.

        * Fixed the silc_server_announce_get_channels to not crash
          on reconnect.  Affected file silcd/server.c.

Wed Nov  7 17:15:07 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added silc_log_set_debug_string function to set a regex
          string to match for debug output.  Only the function names,
          or filenames matching the given debug string is actually
          printed.  This way it is possible to filter out those debug
          strings that user is not interested in.

          Fixed a bug in silc_string_regexify.

          Affected files lib/silcutil/silclog.[ch], and
          lib/silcutil/unix/silcunixutil.c.

        * Changed the -d options in both server and Irssi SILC client
          to take the debug string as argument.  Affected files
          silcd/silcd.c and irssi/src/silc/core/silc-core.c.

Tue Nov  6 21:31:54 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added silc_hash_babbleprint to create a Bubble Babble
          Encoded fingerprint.  The encoding is developed by Antti
          Huima (draft-huima-babble-01.txt), and it creates human
          readable strings out of binary data.  Affected file
          lib/silccrypt/silchash.[ch].

        * Print the babble print now in addition of fingerprint as well
          in Irssi SILC client.  Affected files are
          irssi/src/fe-common/silc/module-formats.[ch],
          irssi/src/fe-common/silc/core/client_ops.c.

Sun Nov  4 23:37:28 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed a security problem found in SKE.  The initiator's
          public key too is now added to the HASH hash value creation
          which is signed by the responder to create the SIGN value.
          This will prevent anyone in the middle to lie to the responder
          about the initiator's public key.  If this is done now, the
          man in the middle will get caught.  Updated the protocol
          specification.

Sun Nov  4 11:43:53 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Better installation directory handling.  Configure module
          paths and other paths automatically to example_silc* files
          in doc/.  A patch by toma.

        * Fixed compiler warning from MPI library, and from SILC RNG.
          A patch by johnny.

        * Added SILC_SERVER_PID_FILE to define the pid file for server.
          It can be configured with ./configure.  A patch by toma.

Sat Nov  3 23:48:23 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Find correct make to use in prepare-clean.  A patch by
          toma.  Affected file prepare-clean.

Sat Nov  3 22:04:00 PST 2001  Brian Costello <bc@mksecure.com>

        * Added irssi variables use_auto_addr, auto_bind_ip,
          auto_bind_port and auto_public_ip.

        * Changed the interface for silc_client_send_key_agreement
          in lib/silcclient/silcapi.h

        Affected files:

         irssi/src/silc/core/silc-core.c
         irssi/config
         lib/silcclient/silcapi.h
         irssi/src/silc/core/silc-channels.c
         lib/silcclient/client_keyagr.c
         irssi/docs/help/key

Sat Nov  3 17:48:55 EET 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added silc_pkcs_public_key_compare to compare two
          public keys.  Affected file lib/silccrypt/silcpkcs.[ch].

        * Check that the client who set the founder mode on the
          channel is the same client that is giving the founder
          mode to itself.  It is done by comparing the saved public
          key (it is saved even in the authentication is passphrase).
          Affected file silcd/command.c.

Fri Nov  2 18:52:08 EST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Do not process packet for disconnected socket connection.
          Affected file lib/silccore/silcpacket.c.

        * Process the DISCONNECT packet through scheduler in the
          client library.  Affected file lib/silcclient/client.c.

        * Fixed the silc_client_packet_parse to not to increase
          the packet sequence number if the conn->sock and the
          current socket connection is not same.  This can happen
          for example during key agreement when the conn includes
          multiple socket connections (listeners).  Affected file
          lib/silcclient/client.c.

        * The sender of the file transfer request now provides also
          the pointer (listener) for the key exchange protocol.  If
          the listener cannot be created then it sends empty key
          agreement and lets the receiver provide the listener.

          Added `local_ip' and `local_port' arguments to the
          silc_client_file_send.  If they are provided they are used,
          if not then it will attempt to find local IP address, if
          not found or bind fails then the remote client will provide
          the listener.

          Affected files are lib/silcclient/client_ftp.c and
          lib/silcclient/silcapi.h.

        * Extended the FILE SEND command to support defining the
          local IP and port for key exchange listener.  They are
          optional.  Affected file irssi/src/silc/core/silc-servers.c.

Thu Nov  1 22:10:07 EST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Defined to WHOIS command reply the sending of fingerprint
          of the client's public key (if the proof of posession of the
          corresponding private key is verified by the server).
          Updated to the protocol specification.

        * Added support of receiving the client's public key's
          fingerprint in command reply in client library.  Affected
          file is lib/silcclient/command_reply.c, and
          lib/silcclient/idlist.[ch].

Thu Nov  1 18:06:12 EST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Do not send over 128 chars long nickname to the server
          in NICK command.  Affected file lib/silcclient/command.c.

        * Do not send over 256 chars long channel names to the server
          in JOIN command.  Affected file lib/silcclient/command.c.

Tue Oct 30 22:48:59 EST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Assure that silc_server_close_connection cannot be called
          twice for same socket context.  Affected file is
          silcd/server.c.

Tue Oct 30 16:58:14 EST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Send error message to application if opening file for
          writing during file transfer fails.  Affected file is
          lib/silcclient/client_ftp.c.

          Remove all file transfer sessions for a client that we're
          removing from ID cache.

          Affected file is lib/silcclient/client_ftp.c.

        * Fixed silc_net_addr2bin to return correct address.  Affected
          file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.

        * Fixed file transfer session removing on signoff notify.
          Affected file irssi/src/silc/core/silc-servers.c.

        * Added the SilcClientFileError to be returned in the monitor
          callback.  Added NO_SUCH_FILE and PERMISSION_DENIED errors.
          Affected file lib/silcclient/silcapi.h.

Mon Oct 29 17:43:04 EST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed a crash in silc_client_ftp_free_sessions and
          silc_client_ftp_session_free_client.  Affected file
          lib/silcclient/client_ftp.c.

        * Added `disabled' field in the SilcChannelEntry in the server
          to indicate if the server entry is disabled.  Affected file
          silcd/idlist.h, silcd/command[_reply].c.

        * SILC server adds now /var/run/silcd.pid everytime it is
          started.  Affected file silcd/silcd.c.

        * Added silc_server_packet_send_clients to send a packet to
          the provided table of client entries.  Affected file
          silcd/packet_send.[ch].

        * Fixed a crash in client resolving in client_prvmsg.c in
          client library.  Affected file lib/silcclient/client_prvmsg.c.

        * Do not actually remove the client directly from ID cache
          during SERVER_SIGNOFF, but invalidate it.  This way we
          preserve the WHOWAS info for the client.  Affected file
          silcd/server_util.c.

        * Fixed SERVER_SIGNOFF notify handling in the server.  The
          server is now able to process incoming SERVER_SIGNOFF notify
          for a server that it doesn't even know about.  It will remove
          the clients provided in the notify.  Affected file
          silcd/packet_receive.c.

        * Check for partial packet in data queue after every packet that
          was found from the queue.  Return and wait for more data if
          there is partial data in queue.  Affected file is
          lib/silccore/silcpacket.c.

Sun Oct 28 18:46:27 EST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added SilcClietFileError enum to indicate error in
          file transfer.  Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
          and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
          Affected files lib/silcclient/silcapi.h and
          lib/silcclient/client_ftp.c.

        * Check that newsize in silc_buffer_realloc is larger than
          the old buffer's size.  Affected file lib/silcutil/silcbufutil.h.

        * Added better monitor of file transfers.  It now monitors
          key agreement protocol during the file transfer too.  Added
          error reporting too.  Affected files
          irssi/src/silc/core/silc-servers.c,
          irssi/src/fe-common/silc/module-formats.[ch].

        * Wrote a help file for FILE command.

        * Added silc_rng_global_get_byte_fast to get not-so-secure
          random data as fast as possible.  Random data is read from
          /dev/urandom if available and from the SILC RNG if not
          available.  It is used in padding generation.  Affected file
          lib/silccrypt/silcrng.[ch].

        * All packets in client library are now processed synchronously.
          Optimized packet processing a lot.  Affected file
          lib/silcclient/client.c.

        * All server connection packets are processing synchronously
          now in server, to optimize packet processing.  Affected file
          silcd/server.c.

        * Include files are installed now only in Toolkit distribution
          if make install is given.  Affected files: all Makefile.am's.

Thu Oct 25 22:44:06 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Assure that silc_client_notify_by_server_resolve does not
          resolve the client information multiple times.  If it cannot
          be found by the first it cannot be found at all.  Affected
          file lib/silcclient/client_notify.c.

        * Fixed WHOWAS command reply calling.  Affected file
          lib/silcclient/command_reply.c.

        * Removed all references to silc_idlist_get_client from the
          Irssi SILC client since that call is internal call used by
          the library.  The Irssi SILC client will use now client
          retrieval functions found in silcapi.h.

        * Fixed a bug in resolving nickname info before sending
          private message.  It used freed memory.  Affected file
          irssi/src/silc/core/silc-servers.c.

Thu Oct 25 19:04:49 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Assure my_channels statistics cannot go negative in server.
          Affected files silcd/server.c, silcd/server_util.c.

Wed Oct 24 19:53:05 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.

Tue Oct 23 13:51:19 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Win32 Toolkit changes.  Affected files
          win32/silc.dsw, win32/libsilc/libsilc.def,
          win32/libsilcclient/libsilc.def,
          lib/silcutil/silcutil.c, and
          lib/sftp/sftp_fs_memory.c.

Mon Oct 22 16:35:05 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added silc_net_localip to return local host's IP address.
          Affected file lib/silcutil/silcnet.[ch].

        * If key exchange or rekey protocol is active for a connection
          parse all packets syncronously since there might be packets
          in packet queue that we are not able to process without first
          processing packets before them.  Affected file silcd/server,
          lib/silcclient/client.c.

        * SilcPacketParserCallback now returns TRUE or FALSE to indicate
          whether library should continue processing the packet.
          Affected file lib/silccore/silcpacket.h.

        * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

          SFTP client requests.  Affected file lib/silcsftp/silcsftp.h,
          lib/silcsftp/sftp_server.c.

        * Added silc_file_size to return file size.  Affected file
          lib/silcutil/silcutil.[ch].

        * Implemented the file transfer support for the client library.
          Added preliminary support for simple client to client one-file
          transmission.  Affected file lib/silcclient/client_ftp.c,
          lib/silccilent/client.[ch].

        * Added new local command FILE to the Irssi SILC Client.
          It is used to perform the file transfer.  It has subcommands
          SEND, RECEIVE, SHOW and CLOSE.  Affected files
          irssi/src/silc/core/client_ops.c,
          irssi/src/silc/core/silc-server.[ch].

Mon Oct 22 12:50:08 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Relay the SILC_PACKET_FTP in the server.  Affected files
          silcd/server.c and silcd/packet_receive.c.

Sun Oct 21 20:21:02 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Renamed silc_file_read and silc_file_write to functions
          silc_file_readfile and silc_file_writefile.  Added function
          silc_file_open and silc_file_close.  Affected files
          lib/silcutil/silcutil.[ch].

Thu Oct 18 20:58:13 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Resolve the client info when received private message or
          channel message for a client which nickname we don't know.
          Affected files lib/silcclient/client_prvmsg.c and
          lib/silcclient/client_channel.c.

        * Do not crash in /KEY if client is not connected.  Affected
          file irssi/src/silc/core/silc-channels.c.

        * Added SilcClientStatus field to the SilcClientEntry in the
          lib/silcclient/idlist.h.

          Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
          is incomplete and is being resolved, it won't be resolved
          twice.

          Make sure also that USERS command reply does not resolve
          twice information.  Affected file is
          lib/silcclient/command_reply.c.

          Make sure that silc_client_get_clients_by_list does not
          resolve twice same information.

        * Check for valid client->id in the silc_server_free_client_data.
          Affected file silcd/server.c.

        * Fixed /GETKEY nick@server not to crash if the server entry
          is not found.  Affected file lib/silcclient/command.c.

        * Fixed the silc_server_check_cmode_rights to check the
          requested modes correctly.  Affected file silcd/command.c.

Thu Oct 18 12:10:22 CEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Better checks for non-printable chars in nick added.
          Affected file silcd/command.c.

Thu Oct 18 09:18:58 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Call the silc_server_udpate_servers_by_server in the
          primary router that comes back online in the backup resuming
          protocol.  Otherwise it routes packets wrong.  Affected file
          silcd/server_util.[ch], silcd/server_backup.c.

Wed Oct 17 16:51:18 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
          lib/silcutil/silcbuffmt.[ch].

        * Redefined the SILC packet header to include the padding
          length.  Affected file lib/silccore/silcpacket.[ch].

        * Added SILC_PACKET_PADLEN_MAX macro to return the padding
          length for maximum padding up to 128 bytes).  Affected
          file lib/silccore/silcpacket.h.

        * Removed all backwards support for old 0.5.x MAC thingies.
          The SILC packet header change makes it impossible to be
          backwards compatible.

        * Send the ENDING packet with timeout in the backup resuming
          protocol.  This is to assure that all routers has connected
          to the primary router.  Affected file silcd/server_backup.c.

        * Changed the RNG to take the first IV from random data.  It
          used to take it from zero actually.  Changed the RNG also
          to use /dev/urandom during session.  /dev/random is used
          in initialization.  Affected file lib/silccrypt/silcrng.[ch].

Tue Oct 16 20:45:49 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Changed the SILC packet header to have the first two bytes
          (the packet length) encrypted.  Affected files aroung the
          code tree, lib/silccore/silcpacket.[ch].  Removed the
          SilcPacketCheckDecrypt callback.  It is not needed anymore
          since the silc_packet_receive_process will determine now
          whether the packet is normal or special.

        * Implemented the unidirectional MAC keys.  Affected files
          lib/silcske/silcske.c, silcd/protocol.c and
          lib/silcclient/protocol.c.

        * Implemented the packet sequence number to the MAC computation.
          Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
          silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
          lib/silcclient/protocol.c.

Mon Oct 15 17:42:55 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Allow backup router to announce servers.  All servers
          announced by backup router are added to the global list
          automatically.  Update hte server's socket to our primary
          router also when backup router announces a server.
          Affected file silcd/packet_receive.c.

        * Do not update the client->router in the function
          silc_server_udpate_clients_by_server if the client is on
          global list.  We might fail to find any specific server
          for locally connected clients and local cell clients.  They
          should still use the `from' and not `to' as client->router.
          This fixes backup router resuming protocol.  Affected file
          silcd/server_util.c.

        * Decrease channel statistics count only if the channel
          deletion worked.  Affected files are silcd/server.c and
          silcd/server_util.c.

        * Added silc_server_update_servers_by_server to update origin
          of all server entries.  Used during backup router protocol.
          Affected files silcd/server_util.[ch], silcd/server.c. and
          silcd/backup_router.c.

        * ROBODoc documented the lib/silccrypt/silchmac.h.  Added new
          function silc_hmac_init, silc_hmac_update, silc_hmac_final,
          silc_hmac_get_hash and silc_hmac_get_name.  Affected file
          lib/silccrypt/silchmac.c.

Sun Oct 14 18:28:22 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Assure that router cannot reroute the same channel message
          to the sender.  Affected file silcd/packet_receive.c.

Sat Oct 13 12:46:18 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Made better checks that the channel message is not sent
          to the router it came from.  Affected file is
          silcd/packet_send.c.  Fixed memory leak too.

        * Announce informations for incoming router connection, but
          only after checking if it is replaced by backup router.
          Affected file silcd/packet_receive.c.

Fri Oct 12 18:37:24 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed the backup resuming protocol to work in multiple
          router environment.  Affected file silcd/server_backup.c.

        * Route packet only to one router in the function
          silc_server_packet_send_to_channel.  Affected file is
          silcd/packet_send.c.

        * Fixed silc_server_send_notify_dest to set the broadcast
          flag.  Fixed the silc_server_send_notify_topic to actually
          send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
          Affected file silcd/packet_send.c.

        * Changed the SFTP Filesystem interface.  Changed the
          SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
          the filesystem operation function.  The SilcSFTPFilesystem
          is now a context that is allocated by all filesystem allocation
          functions and it already includes the operations structure
          and filesystem specific context.  It is given as argument
          now to the silc_sftp_server_start.  This made the interface
          a bit cleaner.  Affected file lib/silcsftp/silcsftp[_fs].h,
          lib/silcsftp/sftp_fs_memory.c and sftp_server.c.

Thu Oct 11 22:19:26 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Changed the backup router adding and getting interfaces
          in the server.  The router that will be replaced by the
          specified backup router is now sent as argument.  Affected
          files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
          silcd/server.c.

        * Added silc_net_addr2bin_ne to return the binary form of
          the IP address in network byte order.  Affected files
          lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].

Thu Oct 11 12:14:19 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Check for existing server ID in silc_server_new_server
          and in silc_server_connect_to_router_final and remove the
          old entry if it exists.  Affected file silcd/packet_receive.c,
          silcd/server.c.

        * Send the channel message always to only one router, either
          in upstream or downstream.  Affected file is
          silcd/packet_send.c.

Tue Oct  9 17:45:43 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Wrote the definition of the backup resuming protocol to the
          protocol specification.

        * Removed one redundant channel key generation from normal
          server during joining procedure.  Removed one redundant
          channel key sending from server to router during joining
          procedure.  Affected file silcd/command.c.

        * Made minor bugfixes to the backup router resuming protocol.
          Affected file silcd/server_backup.c, server.c.

Mon Oct  8 16:47:42 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added --disable-asm configuration option.  Affected files
          configure.in.pre, lib/silcmath/mpi/configure.in.  A patch
          by salo.

        * Implemented the backup resuming protocol that is used to
          resume the primary router position in the cell after the
          primary router comes back online.  Affected files
          silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
          and silcd/server_util.[ch].

Sun Oct  7 12:29:25 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Sleep two (2) seconds after sending QUIT command to server.
          Affected file lib/silcclient/command.c.

        * Assure that if outgoing data buffer is pending do not force
          send any data.  Affected file silcd/packet_send.c.

        * Assure that if outgoing data buffer is pending do not force
          send any data.  Affected file lib/silcclient/client.c.

        * Implemented the backup router support when the primary router
          goes down.  The servers and routers can now use the backup
          router as new primary router without loosing connectivity.

Sat Oct  6 21:18:54 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
          in the server to indicate disabled entry.  All data read
          from the connection will be ignored and no data is sent
          for entry that is disabled.  Affected files are
          silcd/idlist.h, silcd/server.c.

Fri Oct  5 00:03:29 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Created SFTP client and server test programs in the
          lib/silcsftp/tests directory.

Wed Oct  3 23:31:42 EDT 2001  Pekka Riikonen <priikone@silcnet.org>

        * Implemented memory filesystem (virtual filesystem) for
          SFTP server.  Affected file lib/silcsftp/silcsftp_fs.h,
          sftp_fs_memory.c.

Sun Sep 30 22:10:57 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Implemented the SFTP (SSH File Transfer Protocol) to the
          lib/silcsftp.  It includes SFTP client and SFTP server
          implementations.

Sun Sep 30 10:35:44 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Moved lib/silccore/silcprotocol.[ch] to the
          lib/silcutil library.

        * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
          take variable argument list pointer as argument.  Affected
          file lib/silcutil/silcbuffmt.[ch].

        * Added silc_buffer_set function that is used to set data
          to a SilcBuffer that is not allocated at all (SilcBufferStruct).
          Affected file lib/silcutil/silcbuffer.h.

        * Changed various routines in the core library to use the new
          silc_buffer_set instead of allocating new buffer only for
          temporary purposes.

        * Added 64-bit value formatting and unformatting support to the
          silc_buffer_[un]format routines.  Affected file is
          lib/silcutil/silcbuffmt.[ch].

          Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
          to includes/bitmove.h.

Fri Sep 28 21:30:10 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed channel user mode saving in client library.  Affected
          file lib/silcclient/command[_reply].c.

Thu Sep 27 22:52:30 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Defined the file transfer to the SILC Protocol.  Added
          new packet type SILC_PACKET_FTP and defined File Transfer
          Payload.  The mandatory file transfer protocol is SFTP
          (SSH File Transfer Protocol).  Affected file in addition
          of the internet draft is lib/silccore/silcpacket.h.

        * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
          packet SILC_PACKET_RESUME_ROUTER instead.  The new packet
          is used as part of backup router protocol when the primary
          router of the cell is back online and wishes to resume
          the position as primary router.

        * Redefined the MAC generation keys in the protocol.  The
          same key is not used anymore in both direction.  Both
          direction will now use different keys for sending and
          receiving.  This fixes a potential security flaw.  This
          change causes incompatibilities in the protocol.

        * Redefined also the MAC computation from the packet.
          An packet sequence number is now added to the MAC
          computation.  This prevents possible replay attacks against
          the protocol.  This change too causes incompatibilities
          in the protocol.

          Added `sequence' field to the SilcPacketContext to hold
          the current sequence number for the packet.

Wed Sep 26 20:15:22 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added `created' field to the SilcIDListData in the file
          silcd/idlist.h to indicate the time when the entry was
          created.

        * Added `created' field to the SilcChannelEntry too.  Affected
          file silcd/idlist.h.

        * Added `creation_time' aguments to all the announcement functions
          in the server.  If it is provided then only the entries that
          was created after the provided time frame are actually
          announced.  Affected file silcd/server.[ch].

        * The protocol says that the Channel ID's IP address must be
          based on the router's IP address.  Added check for this in
          the silc_server_new_channel when processing incoming New Channel
          Payload.  Affected file silcd/packet_receive.c.

        * Print out the correct version with --version in SILC client.
          Affected file irssi/src/silc/core/silc-core.c.

Mon Sep 24 17:19:00 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed WHOWAS command to check for completnes of the client
          entry always, not just when the command is coming from client.
          Affected file silcd/command.c.

        * Added new function silc_server_packet_queue_purge to purge the
          outgoing data queue to the network.  After the function returns
          it is guaranteed that the outgoing packet queue is empty.
          Affected file silcd/packet_send.[ch].

        * Purge the outgoing packet queue in the rekey protocol's final
          callback to assure that all rekey packets go to the network
          before quitting the protocol.  Affected file silcd/server.c.

        * Added silc_client_packet_queue_parse as similar function as
          in server to the client library.  The affected file is
          lib/silcclient/client.c.

Sun Sep 23 15:15:53 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Splitted silcd/server.c and created silcd/server_util.[ch]
          for utility functions.

        * Added new socket flag SILC_SF_DISABLED to indicate that the
          connection is open but nothing can be sent to or received from
          the connection.  Affected file lib/silcutil/silsockconn.[ch].
          The checking for disabled socket is checked in the low level
          silc_socket_write and silc_socket_read functions.

Thu Sep 20 23:11:28 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Allow only nicknames and channel names that fits into the
          7-bit unsigned char ASCII set.  Affected file silcd/command.c.

Thu Sep 20 18:04:12 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * When processing JOIN command reply in server check that if
          the channel exists in our global list we'll move it the local
          list.  Affected file silcd/command_reply.c.

        * Fixed the check whether client is joined on the channel already
          in JOIN command.  Affected file lib/silcclient/command.c.

        * Fixed the JOIN command reply to check whether the channel
          already exists.  Affected file lib/silcclient/command_reply.c.

Wed Sep 19 22:58:32 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added silc_ske_status_string to map the SKE error numbers
          to readable strings.  The affected files are
          lib/silcske/silcske[_status].[ch].

Tue Sep 18 22:50:41 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Do not show the private channels on the WHOIS channel list
          as it is not allowed by the protocol.  The affected file is
          silcd/server.c.

Sun Sep 16 12:32:58 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Assure that the packet length digged from the actual packet
          is something sensible in the silc_packet_decrypt_rest_special
          in lib/silccrypt/silcpacket.c.

        * Free and NULL the allocated pointer in silc_hmac_alloc if
          the HMAC allocation fails.  The affected file is
          lib/silccrypt/silchmac.c.

        * Print the selected security properties to the log files in
          the server.  Affected file silcd/protocol.c.

        * Add SKE's reference counter even if calling the completion
          callback manually.  Otherwise it goes negative, although it
          does not cause any problems.  The affected file is
          lib/silcske/silcske.c.

        * Remove the client entry with short timeout after giving the
          KILL command.  Affected file lib/silcclient/command.c.

        * Fixed to send error reply in WHOIS and IDENTIFY commands in
          case all found clients are already disconnected (WHOWAS would
          found them) in the server.  Affected file silcd/command.c.

        * Update the last_receive (time of last data received) to be
          updated only when received private or channel message so that
          the idle time showed in WHOIS makes more sense.

        * Added boolean field `valid' in to the SilcClientEntry in the
          client library to indicate whether the entry is valid or not.
          This fixes the nickname change bug on channel when changing
          the nickname to be same than the old (like nick to Nick) the
          nickname formatter doesn't set the new nick anymore to Nick@host.
          Affected file lib/silcclient/idlist.[ch].

        * Now actually fixed the nickname changing on disconnection.
          Added new function silc_change_nick to the Irssi SILC Client.
          Affected file irssi/src/silc/core/client_ops.c,
          irssi/src/silc/core/silc-nicklist.[ch].

Sat Sep 15 13:29:17 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Check that the public key exists in the GETKEY command before
          trying to encode it.  Affected file silcd/command.c.

        * Print some notifications on received public keys with GETKEY
          command in the Irssi SILC Client.  Affected files are
          irssi/src/fe-common/silc/module-formats.[ch],
          irssi/src/silc/core/client_ops.c.

        * Use IDENTIFY command to resolve the server information in the
          GETKEY command instead of INFO command.  Affected file
          lib/silcclient/command.c.

        * All command reply functions in the client library now calls
          the pending command reply callbacks even if an error has
          occurred.  The server has done this a long time and now it was
          time to move the client library to this as well.  Now all
          errors can be delivered back to the pending command reply
          callbacks if necessary.  Affected files are
          lib/silcclient/command[_reply].[ch].

        * Change the nickname on disconnection back to the username
          because in reconnect the server will enforce it to it anyway.
          Affected file irssi/src/silc/core/silc-servers.c.

        * Fixed a config file parsing bug in the Irssi SILC client.
          Affected file irssi/src/silc/core/clientconfig.c.

Thu Sep 13 23:11:18 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * When printing the channel mode on JOIN, verify that the
          channel key and channel's HMAC are valid.  Affected file
          irssi/src/silc/core/client_ops.c.

Thu Sep 13 20:24:52 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
          SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
          lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].

        * Removed channel key rekey task deleting from the function
          silc_server_save_channel_key.  Affected file silcd/server.c.
          Added explicit timeout task context instead that is used to
          delete the task if we are registering a new task before the
          new task has elapsed.

        * When channel key rekey occurs the client library now saves
          the old channel key for a short period of time (10 seconds) and
          is able to use it in case some is still sending channel
          messages encrypted with the old key after the rekey.  Affected
          file lib/silcclient/[idlist.h|client_channel.c].

Sun Sep  9 15:49:16 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added check to the silc_server_new_id_real to not accept
          new ID if it is the sender's own ID.  Affected file is
          silcd/packet_receive.c.

        * Assure that we do not announce ourself or the one we've
          sending our announcements when we're router and are announcing
          servers to our primary router.  Affected file silcd/server.c.

        * Fixed silc_server_command_identify_check_client to assemble
          correct WHOIS packet.  It send corrupted WHOIS packet and
          caused problem with router to router connections.  Affected
          file silcd/command.c.

          Fixed also silc_server_command_whois_check the same way
          as for the IDENTIFY command.

        * Added new SilcIDListStatus to the server in the SilcIDListData
          structure.   The status now includes the current status of
          the entry (like registered, resolved etc.).  Affected file
          silcd/idlist.[ch].  Defined a bunch of different status types
          as well.  This replaced the old boolean registered field as well.

          Added resolve_cmd_ident field to the SilcClientEntry structure
          too so that if the entry is for example being resolved so
          another command may attach to the same pending command reply
          without requiring to resolve the same entry again.  This concept
          should optimize the WHOIS and the IDENTIFY resolving under
          heavy load by taking away unnecessary resolving for entries
          that are being resolved already.

          Added support for adding multiple pending commands for one
          command idenfier.  Affected file silcd/command[_reply].[ch].

        * Fixed WHOIS and IDENTIFY save to remove the cache entry
          before deleting the data.  Otherwise the hash table will have
          freed data in comparison functions.  Affected file is
          silcd/command_reply.c.

        * Fixed silc_idlist_replace_client_id to add the new entry to
          the cache with NULL nickname.  Otherwise there will be invalid
          memory as the nickname after the nickname is freed.  Affected
          file silcd/packet_receive.c.

        * Fixed the silc_idlist_get_clients_by_hash.  The entries was
          saved into wrong slots because the previous number of entries
          was not taken into account.  Affected file silcd/idlist.c.
          Fixed same thing in silc_idlist_get_clients_by_nickname too.

        * If we are router and we receive JOIN notify to a channel that
          does not have any users then notified client is marked as the
          channel founder, as it is it.  The affected file is
          silcd/packet_receive.c

        * Added to the extended hash table API's table_del_*ext functions
          the destructor as argument too, so that the caller can decide
          which destructor to use or whether to use destructor at all.
          Affected file lib/silcutil/silchashtable.[ch].

        * Fixed ID Cache purging.  It actually deleted the entries from
          the hash table after the data was freed.  The hash table ended
          up comparing freed memory.  The affected file is
          lib/silccore/silcidcache.c.

Sat Sep  8 10:22:10 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed Irssi SILC client's KILL command's HELP syntax.

        * The USERS command now resolves the detailed user information
          if the userinfo field is missing.  Affected file is
          lib/silcclient/command_reply.c.

        * Do not print error in silc_file_read if the read file does
          not exist.  Just silently return NULL.  Affected file is
          lib/silcutil/silcutil.c.

        * Fixed the silc_log_output to not wine about NULL filename
          and to not create some bogus " " filename.  Affected file is
          lib/silcutil/silclog.c.

Fri Sep  7 22:16:38 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed various printing bugs on the user interface in the
          Irssi SILC Client.  Minor changes that were forgotten from
          the release.

Fri Sep  7 17:28:37 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed the configure.in.pre and the compilation and distribution
          environment to support the new autoconf 2.52.  That version is
          now required to compile the CVS trunk.

Thu Sep  6 12:47:37 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Renamed function silc_parse_nickname to silc_parse_userfqdn
          to generally parse user@fqdn format strings.  Affected file
          lib/silcutil/silcutil.c.

        * Added nickname_format and nickname_force_format fields to the
          SilcClientParams structure.  The first one defines the format
          for the nicknames that the library will enforce if the receives
          multiple same nicknames.  The second one is boolean value and
          can be used to force the library to always enforce the format
          to the nicknames regardles whether there are multiple nicknames
          or not.  This configurable formatting was employed to flexibly
          support accessing multiple nicknames from the user interface.
          The userinterface can now set the nicknames to what ever format
          they prefer.  Affected file lib/silcclient/silcapi.h.

          Added function silc_client_nickname_format to the file
          lib/silcclient/idlist.c.  It performs the nickname formatting.

          Added new field `hostname´ to the SilcClientEntry context.
          It holds the hostname of the client.  Affected file is
          lib/silcclient/idlist.h.

        * Irssi SILC Client sets the nicknames in nick@hostn format.
          Fe. priikone@otaku, priikone@otaku2 etc.  Affected file
          irssi/src/silc/core/silc-core.c.

          The WHOIS printing now also shows both the real nickname and
          the formatted nickname so that user knows how to access the
          user if there are multiple same nicknames cached.  Affected
          file irssi/src/silc/core/client_ops.c.  Changed the WHOIS
          printing formatting too to take the hostname now as a separate
          argument.  The Affected file is
          irssi/src/fe-common/silc/modules-formats.[ch].

        * Changed the silc_client_get_clients_local to accept the formatted
          nickname as argument.  It accepts the real nickname too but the
          formatted nickname can be used to find the true entry from
          multiple entries.  Affected file lib/silcclient/silcapi.h and
          lib/silcclient/idlist.c.

        * Added nickname_format_parse field to the SilcClientParams.
          It is a callback function provided by the application to parse
          the nickname out of the formatted nickname string. The library
          calls it to get the nickname from the formatted string. Since
          the application generally knows better the format of the nickname
          string it parses it instead of the library, even though library
          encodes the formatted string.  If the callback function is not
          provided then the library will use the string as is.  The
          affected file is lib/silcclient/silcapi.h.

        * All the nickname strings passed to the client library in
          commands are now expected to be formatted nickname strings.
          If the command does not support the formatted nickname string
          it will assume that the sent string is the actual nickname.
          Affected file lib/silcclient/command.c.

Tue Sep  4 22:31:28 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added public key authentication support to OPER and SILCOPER
          commands in the client library.  Affected file is
          lib/silcclient/command.c.

Tue Sep  4 12:39:17 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Changed the get_auth_methdod client operation to be asynchronous.
          It can be async if the application resolves the authentication
          method from the server during the negotiation.  Added new
          SilcGetAuthMeth completion callback that the application will
          call after resolving the authentication method.

          Added function silc_client_request_authentication_method that
          the application can use to resolve the authentication method
          from the server.  Added also SilcConnectionAuthRequest callback
          that the library will call after the server has replied.  The
          application can call this function if it does not know the
          current authentication method.

          Affected files are lib/silcclient/client.c and
          lib/silcclient/silcapi.h.

        * The Irssi SILC client now automatically resolves the authentication
          method incase any configuration information is not present (and
          currently there never is).  The affected file is
          irssi/src/silc/core/client_ops.c.

        * Fixed public key authentication from the client library.
          Affected file lib/silcclient/protocol.c.  Changed also the
          protocol specification about the public key authentication in
          the connection authentication protocol.  The actual data to be
          signed is now computed with a hash function before signing.

        * Fixed the public key authentication from the server as well.
          Affected file silcd/protocol.c.

        * Removed the mlock()'s from the memory allocation routines.
          Affected file lib/silcutil/silcmemory.c.  The ./configure does
          not check anymore for the mlock().  Affected file is
          configure.in.pre.

        * Fixed USERS command in server to allow the execution of the
          command for private and secret channels if the client sending
          the command is on the channel.  Affected file silcd/command.c.

        * Fixed silc_client_get_clients_local to return the clients
          count correctly.  It could return wrong value.  Affected file
          lib/silcclient/idlist.c.

Mon Sep  3 20:09:59 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
          types.  The assembler optimizations seemed not to like 64-bit
          data types.  The assmebler optimizations thus are now enabled
          also for BSD systems as opposed to only enable them for Linux.

        * Do not check for threads at all on BSD systems.  Affected
          file configure.in.pre.

        * Removed -n and -h options from the Irssi SILC Client since
          they are not used in silc.

        * Fixed the prime generation to assure that the first digit
          of the generated random number is not zero since our conversion
          routines does not like number strings that starts with zero
          digit.  If zero digit is seen the random number is regenerated.
          This caused some corrupted RSA keys when the zero first digit
          was met.  Affected file lib/silcmath/silcprimegen.c.

Sun Sep  2 17:17:24 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed WIN32 configuration in the ./configure script.
          Fixed to include xti.h on environments that has it.
          Patches by Carsten Ilchmann and andrew.

Sat Sep  1 00:29:33 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Changed the silc_id_create_client_id to be collision
          resistant.  It is now assured that there cannot be created
          two same client ID's.  I suspect that some weird bugs in
          the server were actually caused by duplicate Client IDs.
          Affected file silcd/serverid.[ch].  A router receiving
          new ID now also assures and informs the sending server
          if the ID caused collision.

        * Changed the silc_id_create_channel_id to also assure that
          there are no collisions.

Wed Aug 29 17:55:01 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Statement about ignoring the Mutual Authentication flag when
          performing rekey with PFS was a bit misleading.  It is ignored
          if it was set in the initial negotiation, it cannot be even
          set in the rekey.  Fixed in the ke-auth draft.  Started the
          new versions of the protocol drafts in the doc/.

Sun Aug 26 14:59:15 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed a bug in silc_client_command_identify_save when saving
          new channel information.  The channel name was no duplicated
          and caused crash on exit.  Affected file is
          lib/silcclient/command_reply.c.

Fri Aug 17 23:07:45 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed the getkey command handling in the server.  Send just
          empty OK reply to the sender if the key could not be fetched
          (but everything else was ok, like the key just was not available).
          Changed the public key parameter to optional in the protocol
          specs so that empty OK reply can be sent.  Affected file
          silcd/command.c.

          Added a message to Irssi SILC client to tell to user if the
          server did not return a public key.

Tue Aug 14 07:29:27 CEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed a channel key regeneration bug.  It registered new
          timeout tasks exponentially until all system resources were
          used.  Affected file silcd/server.c.

Sun Aug 12 20:48:14 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added the SILC Document generator to the scripts/silcdoc.
          It can be used to generate the Toolkit Reference Manual out
          of the source tree.  Internally it will also use the RoboDoc
          generator now imported in util/robodoc.

Sun Aug 12 12:28:17 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added couple of return's in rekey protocol if error orccurred
          during the protocol.  The execution must be terminated.
          Affected file silcd/protocol.c.  Also, terminate the protocol
          always with timeout.

Sat Aug 11 12:36:02 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * The client's Client ID was created initally from the wrong
          nickname (it could have been in format nick@host) in the
          silc_server_new_client.  Affected file silcd/packet_receive.c

Sat Aug 11 00:29:57 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added some SILC_LOG_ERROR's to various error conditions
          if client could not be added to ID cache.  Affected files
          silcd/packet_receive.c and silcd/server.c.

        * When client's sock->user_data is freed, NULL also the
          client->router and client->connection pointers.  Added check
          for these pointers being NULL to various places around the
          code.  Affected file silcd/server.c.

        * Added client->data.registered == TRUE checks to various
          places around the code to assure that unregistered client's
          are not handled when it is not allowed.  Affected file
          silcd/server.c.

        * Added `bool registered' fields to all
          silc_idlist_[server|client]_get_* routines to indicate whether
          the fetched client needs to be registered or not.  Affected
          file silcd/idlist.[ch].

        * Add your own entry as registered to the ID cache in the
          server.  Affected file server.c.

        * Fixed a bug in silc_server_new_server.  The SilcServer was
          set as the new server's context instead of SilcServerEntry.
          This naturally caused some weird bugs.

        * Added "updated" field the SilcChannelEntry which indicates
          the time since the channel entry was last accessed.  This
          can be used to determine whether it is necessary to
          announce the channel after backup resuming protocol.
          Affected files silcd/idlist.[ch].

Thu Aug  9 18:28:37 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Do not delete the channel rekey task when adding it
          for in silc_server_create_channel_key.

        * Changed the silc_server_create_channel_key to return
          TRUE or FALSE to indicate the success of the channel key
          creation.

Thu Jul 26 11:32:31 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed MSVC++ project files and added missing files to
          Makefiles under win32/.

Wed Jul 25 18:43:54 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Do not add TCP_NODELAY flag if the operating system
          does not have it defined.  Affected files are
          lib/silcutil/[unix/win32]/silc[unix/win32]net.c.

        * Fixed buffer overflow from Irssi SILC Client.  Affected
          file irssi/src/fe-common/core/themes.c.

        * Fixed double free in client library in the file
          lib/silcclient/client.c when disconnecting from server.

        * Applied double free patch from cras to Irssi SILC client.
          Affected files irssi/src/core/[modules/expandos].c

        * Fixed the disconnection handling to Irssi SILC Client.
          The application must call silc_client_close_connection
          in ops->connect client operation in case of failure of
          the connection.  Affected file is
          irssi/src/silc/core/client_ops.c.

        * Do not set sock->protocol to NULL in the function
          silc_client_close_connection after executing the protocol's
          final callback since the sock might not be valid anymore.
          Affected file lib/silcclient/client.c.

Wed Jul 25 16:04:35 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Do not enable SILC_THREADS if the linking with libpthread
          did not happen.  Affected file configure.in.pre.

        * Added notion to protocol specification that server must
          verify the sent authentication payload with CMODE when
          setting the channel founder key.  Implemented it to the
          server.  Affected file silcd/command.c.

Mon Jul 23 18:31:43 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added _EXTRA_DIST SILC distribution variable to the
          distributions file.  It is used to conditionally add extra
          files or directories to the specific distribution.  Affected
          files ./prepare, Makefile.am.pre and distributions.

          Removed the `_' from the start of the distribution names.
          It is redundant.

        * Added README.WIN32 for instructions to compile the Toolkit
          under WIN32.

Mon Jul 23 10:12:37 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed a double free in disconnection in the server.  Affected
          file is silcd/server.c.

        * Fixed the lib/silcske/groups.c to work now also with GMP
          MP library.  The string conversion did not work when using
          specific base and the base is indicated in the string as well.

        * Created win32/ directory which now includes MSVC++ specific
          stuff so that toolkit (DLLs) may be compiled with MSVC++.
          It will appear only in the toolkit distribution

Sun Jul 22 19:40:30 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Changed the key material distribution function in case when
          the hash output is too short.  The data is now concatenated
          a bit differently than it used to.  Made the change to the
          SKE protocol specification.

        * Added better GMP detection to configure.in.pre.  A patch
          by salo.

Fri Jul 20 13:16:00 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed a minor bug in SKE that might cause some problem on
          some platforms.  Affected file lib/silcske/silcske.c.

        * Added the cookie checking for initiator in the SKE.  It checks
          that the responder returns the sent cookie unmodified.  The
          affected file is lib/silcske/silcske.c.  Added new SKE
          error type INVALID_COOKIE that can be sent during the
          negotiation.  Fixed some memory leaks as well.

        * Added the "invalid cookie" error message to Irssi SILC client's
          message formats.

Thu Jul 19 21:44:31 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added `task_max' field to the SilcClientParams to indicate
          the maximum tasks the scheduler can handle.  If set to zero,
          default values are used.  Affected file lib/silcclient/silcapi.h.

        * Fixed memory leaks in silc_client_close_connection.  Affected
          file lib/silcclient/client.c.

        * Added silc_client_del_client_entry to client library to free
          all memory of given client entry.  Affected file is
          lib/silcclient/idlist.[ch].

        * Added new functions silc_client_del_channel and
          silc_client_del_server to delete channel and server entries.
          Affected file lib/silcclient/[silcapi.h/idlist.c].

        * Removed silc_client_del_client_by_id from silcapi.h.

        * Fixed the INFO command to return the server's own info
          correctly when querying by Server ID.  Affected file is
          silcd/command.c.

Thu Jul 19 14:47:30 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Removed the non-blocking settings in WIN32 code in the
          silc_sock_[read/write] and added SleepEx instead.  Affected
          file lib/silcutil/win32/silcwin32sockconn.c.  The availability
          of input data is now checked with FIONREAD and ioctlsocket.

Wed Jul 18 18:34:01 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Call silc_schedule_task_del_by_context in the
          silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
          Affected file lib/silccore/silcprotocol.c.

        * Call silc_protocol_cancel for active protocols in the
          silc_server_close_connection if the funtion
          silc_server_free_sock_user_data has not been called.
          Affected file silcd/server.c.

        * Generic tasks cannot be deleted using the del_by_fd
          task deleting function since generic tasks does not match
          any specific fd.  Affected file lib/silcutil/silcschedule.[ch].

        * Added a notion to SILCOPER help file that the SILCOPER works
          only on router server, not on normal server.

Wed Jul 18 09:40:04 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added for WIN32 support for the new scheduler as well.
          Affected file lib/silcutil/win32/silcwin32schedule.c.

        * Fixed the SHA1 implementation to work on various platforms.

Tue Jul 17 23:04:10 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Rewrote the SILC Scheduler entirely.  Removed the old SILC Task
          API.  It is part of the scheduler now.  Everything else is
          as previously but some functions has changed their names.
          Checkout the lib/silcutil/silcschedule.h for the interface.
          Updated all applications to use the new interface.  Affected
          files are lib/silcutil/silcschedule.[ch].

Tue Jul 17 16:53:30 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Found a bug in the SKE implementation.  The HASH value,
          specified by the protocol, was not computed correctly.  The
          public key of the responder was not added to the computation
          even though it is mandatory.  Affected file lib/silcske/silcske.c.
          This unfortunately causes incompatibilities with older
          clients and servers.

        * Added WIN32 specific network init and uninit functions:
          silc_net_win32_init and silc_net_win32_uninit to init and uninit
          the Winsock2.  Affected file lib/silcutil/silcnet.h and
          lib/silcutil/win32/silcwin32net.c.

        * Set the socket always to nonblocking mode on WIN32 after
          reading data or writing data.  Affected file is
          lib/silcutil/win32/silcwin32sockconn.c.

Mon Jul 16 22:55:26 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed various compilation problems under WIN32.  Affected
          files lib/silcutil/win32/silcwin32thread.c and
          lib/silcutil/win32/silcwin32schedule.c.

        * Removed all _internal.h #includes from public header
          files.  Internal headers must never be included from
          public headers.

          Removed also the lib/silcske/payload_internal.h file.

        * All include files that may be needed (public and some others
          included by the public headers) by application developers are
          now copied to the ./includes directory.  It does not copy any
          internal headers.  Affected file Makefile.defines.pre and all
          Makefile.am's under lib/ and subdirs.

Thu Jul 12 17:49:31 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Do not change the ~/.silc directory's permissions automatically.
          Affected file irssi/src/silc/core/clientutil.c.

Thu Jul 12 10:18:40 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Do not cancel the protocol in silc_server_close_connection
          it might cause recursion.  Now cancelled in the function
          silc_server_free_sock_user_data.  Affected file silcd/server.c.

        * Fixed the silc_server_remove_clients_by_server to regenerate
          the channel keys correctly finally.  Added also new function
          silc_server_remove_clients_channels to actually do it.
          Affected file silcd/server.c.

        * Fixed the silc_server_new_channel to not crash by giving
          wrong router to the new channel.  Affected file is
          silcd/packet_receive.c.

Wed Jul 11 18:31:57 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added SilcClientParams structure to the lib/silcclient/silcapi.h
          which is given as argument to the silc_client_alloc now.
          It can be used to configure the client and set various parameters
          that affect the function of the client.

        * The USERS command in server did not check whether the channel
          is private or secret.  Affected file silcd/command.c.

        * Added new argument to the USERS command in protocol specification.
          The USERS command now can take the channel name as argument
          as well.  Added support for this in client and server and
          updated the protocol specs.

        * Completed the GETKEY command in client. It can be now used
          to fetch also servers public key not only some clients.
          Affected files lib/silcclient/command[_reply].c.

        * Added silc_client_get_server to return server entry by the
          server name.  Affected files lib/silcclient/silcapi.h and
          idlist.c.

        * Redefined the IDENTIFY command in protocol specification to be
          more generic.  It now can be used to query information about
          any entity in the SILC Network, including clients, servers and
          channels.  The query may be based either the entity's name
          or the ID.  Added support for this in both client and server.

          Affected files silcd/command.c and lib/silcclient/command.c
          and command_reply.c.

        * Optimized the WHOIS and WHOWAS commands in the server. Removed
          the _from_client and _from_server functions.  Affected file
          silcd/command.c.

        * Added silc_client_get_channel_by_id_resolve to the file
          lib/silcclient/silcapi.h to resolve channel information by
          its ID.  Added also silc_client_get_channel_by_id that
          does not resolve it from the server.

Tue Jul 10 18:05:38 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added SilcServerEntry context into the client library
          to represent one server.  The INFO command now allocates
          these to save the resolved server info.  For now on the
          client library will also keep information about servers,
          connected and resolved with INFO.

          The INFO command now allocates the SilcServerEntry context
          and saves the server info there.  The COMMAND_REPLY in
          the INFO now returns the parameters to application in
          same order as defined in the protocol specification.

          The entries are cached in the client->server_cache.

        * The INFO command is now issued after received the Client ID
          from the server.  Affected file lib/silcclient/client.c.

        * The CMODE_CHANGE notify may now return also an SilcServerEntry
          to the application as the mode changer might be server.
          It is guaranteed that NULL is not returned anymore to the
          application.  Affected file lib/silcclient/client_notify.c.

          The ID Type is now also passed to the application so that
          it can check whether the returned entry is SilcClientEntry
          or SilcServerEntry.

          Added new function silc_client_get_server_by_id to return
          the server entry by ID.  Affected files are the
          lib/silcclient/silcapi.h and lib/silcclient/idlist.c.

        * Do not create the channel in the Irssi SILC Client when issuing
          the JOIN command but when received the sucessful JOIN command
          reply.  Otherwise the channel might get created even though we
          could not join it.  The Affected file is
          irssi/src/silc/core/[silc-channels.c/client_ops.c].

        * Fixed a channel joining bug in router.  The router must also
          check the channel modes, invite and ban lists etc. when serving
          the JOIN command sent by normal server.  Affected file is
          silcd/command.c.  The router now resolves the client's
          information from the server who sent the JOIN command if it
          does not know it, and processes the JOIN command only after
          that.

        * Changed the SilcCommandCb to take new argument; void *context2.
          Affected file lib/silccore/silccommand.h

          The second argument in the command callbacks in the server now
          includes the SilcServerCommandReplyContext if the command was
          called as pending command callback from the command reply.
          Otherwise it is NULL. When called as pending the status of the
          command reply will be checked and if it was erronous the
          error will be sent to the original sender of the command.
          This way the client always receives the error messages even
          though the server was actually the one who received the error
          when it resent the command to router, for example.  Affected
          files silcd/command[_reply].[ch].

        * Fixed sending WHOWAS command's error message to client if
          the requested client could not be found.  It was missing.
          silcd/command.c.

        * Changed the CMODE and CUMODE commands reply arguments in the
          protocol specification.  The Channel ID is now sent in both
          of the commands to identify the channel.  Implemented this
          new feature to the client and server.  Affected files
          lib/silcclient/command_reply.c and silcd/command.c.

        * Made better checks for invite and ban lists in the JOIN
          command in server.  Affected file silcd/command.c.

Mon Jul  9 18:28:34 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * The server now performs the incoming host IP/DNS lookup
          using the silc_socket_host_lookup and thus does not block
          the server anymore.  Affected file silcd/server.c.

        * Completed the multi-thread support for SILC Scheduler in
          the lib/silcutil/silcschedule.c.

        * Fixed the configure.in.pre to detect the pthread correctly
          on various systems.

        * Fixed a deadlock in silc_task_queue_wakeup in the file
          lib/silcutil/silctask.c.

Mon Jul  9 13:40:03 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added new function silc_schedule_wakeup that is used in
          multi-threaded environment to wakeup the main thread's
          schduler. It needs to be used when a thread adds a new task
          or removes a task from task queues. After waking up, the
          scheduler will detect the task queue changes. If threads
          support is not compiled in this function has no effect.
          Implemented the wakeup mechanism to both Unix and WIN32
          systems.  Affected files are lib/silcutil/silcschedule.[ch],
          lib/silcutil/unix/silcunixschedule.c and the
          lib/silcutil/win32/silcwin32schedule.c.

        * Added new function silc_task_queue_wakeup to wakeup the
          scheduler by the specified task queue.  Affected file
          lib/silcutil/silctask.[ch].

        * The silc_socket_host_lookup_start now wakes up the scheduler
          after adding the timeout task.  Affected file is
          lib/silcutil/silcsockconn.c.

        * The silc_socket_host_lookup is synchronous now if the threads
          support is not compiled in.  However, the callback is still
          called asyncronously through the scheduler, anyway.  Affected
          file lib/silcutil/silcsockconn.c.

Mon Jul  9 00:24:45 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added new function silc_socket_host_lookup to perform
          asynchronous IP and FQDN lookups for the socket connection.
          Affected files lib/silcutil/silcsockconn.[ch].

Sun Jul  8 18:44:53 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added SILC_MUTEX_DEFINE to define the mutex on environments
          that may or may not compile the mutex support in.

          Changed the silc_mutex_alloc interface. It allocates the
          mutex now to the sent pointer and returns TRUE or FALSE.

          Affected file lib/silcutil/silcmutex.h.

        * Wrote the SILC Task Queue interface to support multi-threads.
          Affected file lib/silcutil/silctask.[ch].

        * Wrote the SILC Scheduler to support multi-threads.  Affected
          file lib/silcutil/silcschedule.c.

Sun Jul  8 11:16:01 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Implemented the SILC Mutex API and SILC Thread API for WIN32
          in lib/silcutil/win32/.

Sun Jul  8 00:18:15 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Defined SILC Mutex API and SILC Thread API and implemented
          them for Unix.  Affected files are
          lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
          lib/silcutil/unix/silcunixmutex.c and
          lib/silcutil/unix/silcunixthread.c.

Sat Jul  7 14:40:31 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed the silc_server_remove_clients_by_server's channel
          key re-generation.  The hash table handling was incorrect
          and would not work with many channels.  Affected file is
          silcd/server.c.

        * Fixed some memory leaks around the server code.

        * Rewrote the silc_server_get_users_on_channel to support IPv6
          based Client ID's.  Affected file silcd/server.c.

        * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
          specification.  However, a separate document must be written
          to define the detailed signing procedure and the payload
          associated with the flag.  Defined the flag to the
          lib/silccore/silcchannel.h as well.

Fri Jul  6 18:26:31 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Changed the dynamic tables to static size tables in the
          lib/silccrypt/silchmac.c.

        * Removed GCC dependencies from the code.  A patch by cras.

Fri Jul  6 09:39:35 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Do not show the error "Error receiving packet bla bla"
          in server if it really was not an error (-2 means that reading
          is pending).  Affected file silcd/server.c.

Thu Jul  5 21:22:32 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed a possible crash in silc_server_remove_clients_by_server
          in silcd/server.c.  Fixed there also some memory leaks.

        * Fixed the silc_idlist_replace_client_id.  It could replace
          wrong key in the hash table.  Affected file silcd/idlist.c.

        * Do not check whether there are global users on the channel
          if the channel->global_users is FALSE.  Affected functions
          silc_server_remove_from_one_channel and
          silc_server_remove_from_channels in silcd/server.c.  Also,
          do not check if the removed client is local as we can be
          sure that global client was not removed from the channel
          and checking for global users is not needed.

        * The silc_server_remove_clients_by_server now re-generates
          the channel keys correctly for those channels that had
          clients removed from them.  Affected file silcd/server.c.

Tue Jul  3 11:39:20 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Found the reason of random crashes in the server.  We weren't
          ignoring the SIGPIPE signal (which can be sent in write())
          and it crashed the server.  Affected file silcd/silcd.c.

Fri Jun 29 20:05:25 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Assure that sock->user_data is not NULL in the function
          silc_server_packet_send in silcd/packet_send.c.

        * Disconnect the remote connection if it could not be added
          to any ID lists in the server.  The affected file is
          silcd/server.c.

        * Check in silc_server_packet_send[_real/dest] that the
          socket is not disconnecting and ignore the data if it is.
          Affected file silcd/packet_send.c.

        * Define inline to __inline on native WIN32 compilation.
          Affected file includes/silcwin32.h.

        * Added some explicit type casts for inline code since MSVC
          require them.  Affected files lib/silcutil/silcbuffer.h,
          lib/trq/silcdlist.h and lib/trq/silclist.h.

        * Print warning in log files from now on if the packet
          decryption fails.  Affected file silcd/server.c.

Thu Jun 28 21:30:39 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Changed the `say' client operation's interface to accept
          new `type' argument to indicate the type of the message sent
          by the library.  The application may filter the library's
          messages according the type.  The affected file is the
          lib/silcclient/silcapi.h.

        * Added two new functions to lib/silcclient/silcapi.h:
          silc_client_del_client and silc_client_del_client_by_id.
          Affected file lib/silcclient/idlist.c.

        * Moved the clientincludes.h from includes/ to silc/ and
          serverincludes.h from includes/ to silcd/.

        * The modes for the CMODE and CUMODE are now passed as
          uint32 for application with COMMAND_REPLY.  The affected
          file is lib/silcclient/command_reply.c.

Wed Jun 27 22:24:47 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * /WHOIS without arguments shows client's own information.
          Affected file lib/silcclient/command.c.

        * Changed PING to not accept any arguments.  The specs
          says that client can ping only the connected server so
          requiring an argument is not needed.  Affected file is
          lib/silcclient/command.c.

Wed Jun 27 00:10:33 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Fixed a fatal bug in private message sending and reception
          encryption and decryption when using private message keys.
          The implementation was incorrect and did not follow the
          specification.  It causd that some of the message were
          lost since it did not use the sending and receiving keys
          as the protocol suggests.  This has been fixed and will cause
          incompatibilities with older clients when sending private
          message encrypted with private message keys.  Affected files
          lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
          and various other in Irssi SILC Client.

          Added `responder' boolean argument to the functions
          silc_client_add_private_message_key[_ske] to indicate when
          the key is added as responder or initiator of the key
          negotiation.

Tue Jun 26 19:23:07 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Removed the silc_ske_check_version function and created
          a SilcSKECheckVersion callback.  Added also a function
          silc_ske_set_callbacks that is now used to set all SKE
          callbacks.  The callback functions are not given to
          the SKE functions anymore, but this function is used to
          set the callbacks.

        * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.

        * Added `silc_version' argument to the silc_client_alloc
          to define the version of the application for the library.
          The library will use the version string to compare it
          against the remote host's (usually a server) version
          string.  Affected file lib/silcclient/silcapi.h

        * Added the KE protocol context to Key Agreement context
          in client library so that we can abort the SKE if it
          is in process when we get timeout.  Affected file is
          lib/silcclient/client_keyagr.c.

        * Do not resolve the client ID forever if it returns in the
          first time that such client does not exist.  This was done
          for example with private message.  Affected file is
          lib/silcclient/client_prvmsg.c.

Mon Jun 25 21:42:51 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Do not add regex.h for WIN32.  The affected file
          includes/silcincludes.h.

        * Added WIN32 DLL generation to lib/Makefile.am.pre.  It might
          not work yet 100%.  It generates the DLL's automatically
          when compiling with --with-win32 under cygwin.

Sun Jun 24 19:49:23 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * lib/contrib/regex.c is not compiled on WIN32.

        * Added silc_net_get_socket_opt function to the
          lib/silcutil/silcnet.h.

        * Added includes/silcwin32.h for WIN32 specific includes
          and definitions.

        * Do not use ptime structure or any of the posix process
          functions on WIN32 in lib/silccrypt/silrng.c.

        * Added silc_gettimeofday to provide generic function
          for struct timeval on all platforms.  Added the function
          to lib/silcutil/silcutil.h.

Sun Jun 24 12:19:52 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Moved the lib/silccore/silcsockconn.[ch] to the utility
          library as they clearly belong there.  As a plus side we
          can make the actual socket connection routines platform
          specific.

          Added also new generic function silc_socket_read and
          silc_socket_write (that used to be silc_packet_[read/write].
          The implementation of these are platform specific.

        * Added WIN32 specific routines of silc_socket_[read/write]
          to lib/silcutil/win32/silcwin32sockconn.c.

Sat Jun 23 16:01:00 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Added preliminary support for native WIN32 compilation under
          cygwin (using the -mno-cygwin option for GCC) to the
          ./configure.in.pre.  The --with-win32 now prepares the
          compilation for native WIN32.

        * Rewrote the SILC Scheduler interface in the file
          lib/silcutil/silcschedule.h.  The scheduler is now context
          based and does not have anymore any global static scheduler.
          Moved the Unix scheduler to the lib/silcutil/unix/ directory
          and created lib/silcutil/win32 directory for WIN32 based
          scheduler.

        * Added Unix specific network routines to the
          lib/silcutil/unix/silcunixnet.c and the old
          lib/silcutil/silcnet.c includes now only generic routines.

          Added WIN32 specific network routines to the
          lib/silcutil/win32/silcwin32net.c.

        * Added Unix specific utility functions from the
          lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.

        * Added WIN32 SILC Scheduler to the file
          lib/silcutil/win32/silcwin32schedule.c. The code is of course
          untested.

Fri Jun 22 10:44:14 EEST 2001  Pekka Riikonen <priikone@silcnet.org>

        * Do not handle JOIN notify in the server if the target client
          is not registered (idata->registered == FALSE).  The affected
          file is silcd/packet_receive.c.

        * Update the nickrec->founder in event_cumode in the Irssi SILC
          client.  Affected file irssi/src/silc/core/silc-channels.c.

        * Fixed the CUMODE_CHANGE notify handling in the server when
          server and router are announcing their clients on channels.
          Now the mode changes are saved and notified correctly.  The
          affected file is /silcd/packet_receive.c.

        * Fixed silc_idlit_replace_[server/client/channel]_id functions.
          They really did not replace the cache entry in the ID Cache.
          Now they do that.  Affected file silcd/idlist.c.

        * Fixed the KICK notify handling in the Irssi SILC client to
          update the channel records so that the kicked client does not
          appear to be on the channel.  The affected file is
          irssi/src/silc/core/silc-channels.c.

        * Always update the conn->current_channel when executing command
          on a channel.  Affected file irssi/src/silc/core/silc-servers.c.

        * Fixed the KILL notify handling in Irssi SILC client to remove
          the killed client on all channels.

Thu Jun 21 17:10:08 CEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed the silc_parse_command_line to remove extra spaces
          from the start and end of the arguments.  Affected file is
          lib/silcutil/silcutil.c.

        * Cancel and free any active protocol in the function
          silc_server_close_connection.  Affected file silcd/server.c.

        * Cancel and free any active protocol in the function
          silc_client_close_connction.  Affected file is
          lib/silcclient/client.c.

        * Do not execute the KILL command for clients that are in
          history (ie. they are not in the network).  Affected file is
          silcd/command.c.

        * Fixed KILL notify handling, client does not crash anymore.
          Affected file irssi/src/silc/core/silc-channels.c.

        * Reduced the default packet buffer size from 2048 to 1024 in
          lib/silccore/silcpacket.c.

        * Added SILC_SKE_STATUS_FREED SKE status type and a reference
          counter to the SKE context that is incresed when the SKE library
          performs async operation outside the library.  If the outside
          process frees the SKE context and FREED status will be set
          and the library will detect after the sync operation that the
          libary is freed.  The affected files are
          lib/silcske/silcske[_status].[ch].

        * Resolve the client entry information in the function
          silc_client_channel_message to assure that NULL pointer is not
          passed as client entry to the application. */

        * Fixed the task timeout calculation to assure that there is
          never negative timeouts.  The affected file is
          lib/silcutil/silcschedule.c.

        * Fixed the channel user mode notification sending in server.
          It was sent point-to-point to the router (or to server by router)
          but it needs to be destined to a channel.  The routines now
          supports sending the channel user mode notifys to the channels
          when announcing clients and channels.  Affected files are
          silcd/server.c and silcd/packet_receive.c.

        * Fixed the CHANNEL_CHANGE notify handling in the client libary.
          It did not actually replace the old channel entry in the cache.
          Affected file lib/silcclient/client_notify.c.

Tue Jun 19 22:10:36 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed a possible crash in silc_packet_send_prepare.  It now
          assures always that there is enough space in the buffer and
          at the tail area of the buffer (for MAC).

          Fixed the inbound buffer reallocation in silc_packet_read.
          It was old code and did not handle the reallocation correctly.
          Affected

          The affected file is lib/silccore/silcpacket.c.

        * Fixed buffer overflow in silc_parse_nickname in the file
          lib/silcutil/silcutil.c.

Tue Jun 19 13:40:09 CEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * make install generates new server keys only if there is not
          keys already.

Mon Jun 18 18:49:07 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
          Added check that if the NOREPLY is set then we will not send
          the away message.  This avoids infinite loop of away messages
          if both clients are away.  The affected file is
          lib/silcclient/client_prvmsg.c.

        * Fixed client crash if /NICK was given without arguments.
          Affected file lib/silcclient/command.c.

        * Server does not send the invite list in INVITE command back
          to the client if the list was not altered.  Added this notion
          to the protocol spec as well.  Affected file silcd/command.c.

          Fixed possible crash in INVITE command by checking the
          value of silc_server_get_client_route command.

        * Fixed the INVITE notify type handling.  The arguments are now
          taken in correct order and client does not crash.  The affected
          file is irssi/src/silc/core/silc-channels.c.

          Removed the "Inviting xxx to channel" message from the
          client library away and let the application handle it.
          Affected file lib/silcclient/command.c.  Added that message
          to Irssi SILC client's message formats.

        * Fixed CMODE command crash in client.  It now checks the
          amount of arguments correctly and does not crash.  The affected
          file is lib/silcclient/command.c.

        * Do not create new channel automatically in silc_channels_join
          but check whether the channel by that name already exists.
          Affected file irssi/silc/core/silc-channels.c.

        * Do not send the SERVER_SIGNOFF to router if the disconnected
          entity was the router.  Affected file silcd/server.c.

        * Added the handling of the SERVER_SIGNOFF notify to the Irssi
          SILC client as it was missing from there.

          Added the handling of the KICK notify to the Irssi SILC client
          as it was missing.  Added "you have been kicked" message to
          Irssi SILC client's message modules formats.

          Added the handing of the KILL notify to the Irssi SILC client
          as it was missing.  Added the kill message module formats
          as well.

          The affected file is irssi/src/silc/core/silc-channels.c.

        * The router did not save the channel mode the server announced.
          Affected file silcd/packet_receive.c.

        * Fixed a possible crash in INFO command in server.  If the
          server did not provide the server info it crashed.  Affected
          file silcd/command.c.

Sun Jun 17 15:26:05 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed the GETKEY command in the server to check also the
          global list.  Otherwise the GETKEY would not work correctly
          in normal SILC server.  Affected file silcd/command.c.

Sat Jun 16 18:00:00 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed GETKEY crash, it crashed if the command did not succseed.

Tue Jun 12 21:36:18 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
          is now real and not just an macro interface to GMP.

          Removed the entire GMP from the source tree and imported new
          NSS MPI library instead.  Reason for removing GMP is that it is
          extremely large and compiles extremely slow.  The NSS MPI
          is only a few files and compiles in less than 10 seconds.
          The speed is also about the same as GMP.  The MPI is imported
          to lib/silcmath/mpi.

          If the system has GMP installed we will still use the GMP.
          If it is not then the NSS MPI will be compiled.

Mon Jun 11 18:07:24 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Merged a long nickname (127 characters long) crash bugfix from
          Irssi CVS tree.  Affected file irssi/src/core/misc.c.

        * Merged a freed memory reference bugfix from Irssi CVS tree.
          Affected file irssi/src/core/commands.c.

Sun Jun 10 16:08:35 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added the server's public key sving and verification to the
          server when performing the SKE.  This was missing and the
          remote server's (or router's) public key was accepted without
          checking whether we have it previously or trust it at all.
          Affected file silcd/protocol.c.

Sat Jun  9 20:17:30 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Check in the silc_server_timeout_remote if protocol is active
          and make sure that the protocol's final callback is called so
          that all memory if freed.  Affected file silcd/server.c.

Sat Jun  9 12:51:27 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * silc_server_whois_send_reply crashed the server if the nickname
          was 127 characters long.  Affected file silcd/command.c.

Thu Jun  7 16:29:56 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added sanity check to the silc_server_new_client. If the hostname
          is provided inside username then check that the provided hostname
          really is the same as the resolved one.  If the hostname was not
          resolved then check it from the public key.  Affected file is
          silcd/packet_receive.c.

        * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
          if the server disconnected us and the connection is not valid
          anymore.  Affected file irssi/src/silc/core/silc-channels.c.

        * Moved the silc_client_[chmode|chumode|chumode_char] away from
          the library to the lib/silcutil/silcutil.[ch].

Thu Jun  7 08:57:16 CEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Close log file after open.  Affected file
          lib/silcutil/silclog.c.

        * Check whether sock == NULL in silc_client_send_packet and return
          if it is.  Affected file lib/silcclient/silcclient.c.

        * Check rec->entry == NULL in the Irssi SILC Client before
          sending the channel message.  Affecte file is
          irssi/src/silc/core/silc-servers.c.

Tue Jun  5 08:08:21 CEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Merged a splitted window bugfix from Irssi CVS tree.  The
          affected file is irssi/src/fe-text/textbuffer-view.c.

        * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
          It did not print nickname.

        * Improved the distributions system a bit.

Mon Jun  4 17:57:16 CEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
          irssi/src/fe-text/gui-window.c.

        * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
          to in-active server.  The affected file is
          irssi/src/silc/core/client_ops.c.

        * Resolve the client in USERS command reply if the entry does
          not have username resolved.  The affected file is
          lib/silcclient/command_reply.c.  Also, changed the IDENTIFY
          command to WHOIS command to really resolve stuff.  The USERS
          is not used any more in any critical section so WHOIS can
          be used even though it might be slower than IDENTIFY.

        * Changed the lib/silcutil/silchashtable.h header to ROBODoc
          format.

Sun Jun  3 14:21:32 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Changed the protocol API a bit more consistent in the
          lib/silccore/silcprotocol.[ch].

        * Changed the following headers to ROBODoc format:

                lib/silccore/silcpayload.h
                lib/silccore/silcprotocol.h
                lib/silccore/silcsockconn.h

          All core library headers are now formatted.

Sat Jun  2 10:45:09 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed a bug in Irssi SILC client; do not show that you are
          server/router operator if you really are not.  Affected file is
          irssi/src/silc/core/client_ops.c.

        * Renamed silc_command_free_payload to silc_command_payload_free.
          Affected file lib/silccore/silccommand.h

        * Added silcmath.h to include the prototoypes of various routines
          in the lib/silcmath.  Removed the old modinv.h, mpbin.h and
          silcprimegen.h.

        * Changed the following headers to ROBODoc format:

                lib/silccore/silcchannel.h
                lib/silccore/silccommand.h
                lib/silccore/silcid.h
                lib/silccore/silcidcache.h
                lib/silccore/silcmode.h
                lib/silccore/silcnotify.h
                lib/silccore/silcpacket.h
                lib/silcmath/silcmath.h

Fri Jun  1 22:19:37 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added checking to the server code not to start the server if
          ciphers and stuff are not configured properly.  Affected files
          silcd/serverconfig.[h] and silcd/server.c.

        * Changed the layout of the header files of the public interfaces
          in the SILC libraries.  The new layout supports ROBODoc
          documentation tool (and some others) so that it is easy to create
          a library reference manual.  All the other headers and source
          code must still follow the CodingStyle document.  Also source
          code must not include these ROBODoc stuffs, only the headers.
          Furthermore, all public interface headers must now be named
          by using `silc' prefix, example: silcapi.h, silccipher.h.
          Some files were renamed due to this.  All the other headers
          must not be used as public interfaces.  I will update the
          CodingStyle document later.  Changed following headers, so far:

                lib/silcclient/silcapi.h
                lib/silccore/silcauth.h
                lib/silccore/silcprivate.h
                lib/silccrypt/silcdh.h

Fri Jun  1 10:28:09 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Updated TODO.

        * Removed silc_client_packet_send_flush from the client library
          as it is not needed.  Affected file lib/silcclient/client.[ch].

        * Added printing of message of unresolved authentication method
          to the Irssi SILC client.  Added it to the module formats.
          Removed the same message from the client library.

Thu May 31 13:57:33 CEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added new distribution feature, DISTLABEL.  Every distribution
          can define own preprocessor label that can be used in the
          source code.  For example: #ifdef SILC_DIST_CLIENT.  Affected
          file distributions, acconfig.h.pre and prepare.

Tue May 29 22:16:40 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added Makefile.defines_int to include the actual definitions
          for Makefile.defines.in.  Tested the new distribution system,
          created distributions and tested installation.

        * Added AWAY message printing to the Irssi SILC client.  Added
          the messages to the irssi/src/fe-common/silc/module-formats.[ch].

        * Added SCONNECT command to call the SILC's CONNECT command.
          Cannot use CONNECT directly since Irssi uses that internally.
          Affected file irssi/src/silc/core/silc-servers.c.

          Added ACTION local command.  It is same as ME command but takes
          the channel as mandatory argument.

          Rewrote some of the Irssi's help files to suite for SILC
          protocol.

Mon May 28 19:05:22 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added Makefile.defines[.in] that should for now on be included
          in all Makefile.am file in the source tree.  That file includes
          all common compilation definitions for SILC source tree.

Mon May 28 10:30:51 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Minor changes to the ./prepare script to change the package
          name according the distribution name to the configure.in.

Sun May 27 22:24:57 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Created new distribution system.  Added file `distributions'
          that defines all the distributions that can be created out of
          the SILC source tree.  The ./prepare script now reads that
          file to determine how to prepare the distributions.  The
          first argument to the ./prepare is the name of the distribution
          and second is the version of the distribution.  If given
          without arguments it creates the default (toolkit) distribution
          with the default version (defined in ./prepare).

          All Makefile.am files that are subject to the distributions
          are now named as Makefile.am.pre.  These are ./Makefile.am
          and lib/Makefile.am.  Others may be changed later.

Sun May 27 15:57:17 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added invite list, ban list, some key management and connection
          error message printing to module formats in the Irssi SILC client.

        * Added new silc_client_set_away_message to set the away message
          that is back to the person who sent private message.  The
          affected file lib/silcclient/silcapi.h and the
          lib/silcclient/client_prvmsg.c.

Sun May 27 12:39:48 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed the private message sending in the Irssi SILC client,
          added local command KEY to the Irssi SILC client.

          Added key management and key agreement message formats to the
          irssi/src/fe-common/silc/module-formats.[ch].

          Added USERS (alias WHO) printing, server/router operator
          indication and LIST command printing to the module formats.

Sat May 26 17:43:42 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed channel joining notify handling, cumode notify handling
          from Irssi SILC client.

        * Added SILC specific module-formats to the Irssi SILC client so
          that SILC specific message hilighting, colors etc is possible.
          Affected file irssi/src/fe-common/silc/module-formats.[ch].

          Added channel mode, channel user mode, actions, notices,
          whois and whowas printing to the the module-formats.c.

        * Fixed a bug in channel deletion in the server.  The channel
          is not left to the cache even if the channel founder auth mode
          is set when there are no users anymore on the channel.  Affected
          file silcd/server.c.

        * The silc_net_localhost now resolves the entire hostname including
          the domain name.  Affected file lib/silcutil/silcnet.c.

Sat May 26 12:13:37 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Changed the ask_passphrase client operation to be ascynchronous.
          It has now a completion callback and a context that the
          application must call after it has got the passphrase from
          the user.  Affected files lib/silcclient/silcapi.h,
          lib/silcclient/protocol.c, lib/silcclient/command.c and
          silc/client_ops.c.

          Added SilcAskPassphrase callback that the application calls
          to deliver the passphrase to the library.

        * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
          The public key verification and especially a certificate
          verification is asynchronous procedure.

          Added new SILC_SKE_STATUS_PENDING status to indicate the
          request is pending and a callback will be called to finalize
          the request.

          Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
          indicate that remote end did not send its public key (or
          certificate), even though we require it.  Added check for this
          condition in the SKE.  This was a security bug, now fixed.

          Defined new SilcSKEVerifyCbCompletion callback that is called
          when the verification process is completed.

          The affected files lib/silcske/silcske_status.h and
          lib/silcske/silcske.[ch].

        * Changed the verify_public_key client operation to be async
          as well.  Defined SilcVerifyPublicKey callback that is used to
          indicate the success of the public key verification process.

          Changed the server and client to use the new async client
          operations.

        * Changed the Irssi SILC client's internal scheduler to be called
          twice as many times as it used to be.  As a result the client
          should be a bit faster now.  Affected file is
          irssi/src/silc/core/silc-core.c.

        * Added support to Irssi SILC client of asynchronous public key
          verification and passphrase inquiry.  Affected file is
          irssi/src/silc/core/silc-core.c.

Fri May 25 14:38:38 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Do not say "You have left channel %s" in client library.
          Moved it to the application.  Affected files are
          lib/silcclient/command.c and silc/client_ops.c.

        * Fixed silc_client_get_clients.  Command context was not
          duplicated and was freed memory in the callback.  Affected
          file lib/silcclient/idlist.c.

        * Do not say "you are now talking..." on JOIN command in the
          client library.  The appliation must handle it.

        * Do not say ".. changed topic to" in command reply in the
          client libary.  The application must handle it.

        * Fixed TOPIC command sending in the client library.

        * Fixed a memory leak in silc_client_command_free in the file
          lib/silcclient/command.c.

Thu May 24 19:08:55 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Imported a modified version of Irssi client to the source tree.
          The Irssi will be used to create a new client called
          Irssi SILC.  Imported to irssi/.

          Added silc_core_init_finish function to the Irssi.  Affected
          file irssi/configure.in.

          A lot changes in the Makefile.ams around the irssi tree.

Tue May 22 22:23:49 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Do not rehash if the new size is same as the old size of the
          hash table, in the silc_hash_table_rehash*.  The affected file
          lib/silcutil/silchashtable.c.

        * Replaced hash_table_del_by_context calls from the server
          (when channel->user_list and client->channels) to the
          hash_table_del as it is sufficient and faster.

Tue May 22 17:27:16 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added silc_hash_table_list, silc_hash_table_get and the
          SilcHashTableList structure to provide an alternative way to
          traverse the hash table.  The affected files are
          lib/silcutil/silchashtable.[ch].

        * Changed the server's idlist routines to use the hash table
          routines to optimize the code.

Mon May 21 21:46:20 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Replaced the client entry's `channel' list and channel entry's
          `user_list' list to hash tables for optimized lookup.  Changed
          the code to use the hash table interface around the code.
          Affected file lib/silcd/idlist.[ch].

        * Added `auto_rehash' boolean argument to the function
          silc_hash_table_alloc to indicate whether the hash table should
          auto-rehash when it thinks is appropriate time.  It will
          increase the hash table size if the there is twice as much
          entries in the table than the size of the table, and will
          decrease the size if there are twice as less entries than
          the size of the table.

Mon May 21 09:51:11 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed silc_xxx_get_supported to not crash at some circumstances.

Sun May 20 13:45:58 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * silc_idcache_purge_by_context deletes the entry now by context
          as it is supposed to do.  Affected file lib/silccore/idcache.c.

        * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
          client is not anymore valid (WHOWAS givens the info) and not
          the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.

Sat May 19 16:30:03 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Removed the `data' and `data_len' arguments from the ID Cache
          interfaces and added `name' argument.  ID Cache does not handle
          anymore the binary data only a names associated with given ID.

        * When hashing a Client ID with silc_hash_id the entire ID is
          not hashed anymore, instead only the hash of the Client ID is
          hashed.  This way we can access the Client ID from the cache
          with Client ID but with the hash of the ID (which is a hash of
          the nickname) as well without any difference in performance.

          Added also silc_idcache_find_by_id_one_ext to do one on one
          searching when we have the actual ID.  Added also function
          silc_hash_client_id_compare.  The affected files are
          lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].

        * When hashing the name associated with a ID it is always done
          in lowercase.  This way we can access the cache without worrying
          about case-sensitivity, even though, for example nicknames are
          case sensitive.

        * Fixed a bug in server with channel message sending.  It put
          wrong ID type as destination ID.  The affected file
          silcd/packet_send.c.

        * silc_idcache_del_by_context now deletes from all hash tables
          by context.  Affected file lib/silccore/idcache.c.

Fri May 18 17:42:00 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Changed the client library to use the new ID Cache interface.
          Changes around the source tree.

        * Added silc_hash_table_rehash_ext to rehash with specific
          hash function.  Affected file lib/silcutil/silchashtable.[ch].

        * Added silc_hash_string_compare to compare two strings in the
          hash table.  Affected file lib/silcutil/silcutil.[ch].

Fri May 18 11:18:45 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added new function silc_idcache_del_by_context into the
          lib/silccore/idcache.[ch].

        * Changed the server's ID list routines to use the new ID Cache
          interface.  Changes around the source tree.

Fri May 18 08:35:31 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added silc_hash_table_del[_by_context]_ext functions in to the
          lib/silcutil/silchashtable.[ch].

          Removed silc_hash_table_find_all* routines and added new
          silc_hash_table_find_foreach to replace them.

          Added silc_hash_table_replace_ext function as extended
          replacing function.  Separated the simple hash table interface
          from the extended hash table interface in the file
          lib/silcutil/silchashtable.h.

        * Fixed minor bugs and changed it to use some of the new
          hash table functions in lib/silccore/idcache.c

Thu May 17 18:15:12 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added new function silc_hash_table_find_all to return all keys
          in the hash table by the specified key.  As the hash table is
          collision resistant it also makes it possible to have several
          duplicate keys in the hash table.  This function may be used to
          find all of the keys from the hash.

          Added user_context arguments to the SilcHashFunction,
          SilcHashCompare and SilcHashDestructor to deliver user specified
          context.

          Added new fuctions silc_hash_table_find[_all]_ext to do
          extended lookup with specified hash and compare functions and
          specified user contexts.

          Added new function silc_hash_table_add_ext to add the key
          with specified hash function and user context.

          Added new function silc_hash_table_foreach to traverse all
          entrys in the hash table.  Added SilcHashForeach callback
          function.

          Added new function silc_hash_table_del_by_context to delete
          the entry only if the context associated with the key matches.

          Affected files are lib/silcutil/silchashtable.[ch].

        * Removed silc_hash_[server/client/channel]_id and added just
          silc_hash_id to the lib/silcutil/silcutil.[ch].  Added also
          silc_hash_id_compare to compare two ID's using as the hash table
          comparison function.  Added also silc_hash_data to hash
          binary data and silc_hash_data_compare to compare it.

        * Removed silc_idlist_find_client_by_hash as it is not needed
          anymore.  Affected file silcd/idlist.[ch].

        * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
          to use internally the SilcHashTable.  The new ID Cache is a lot
          faster than the old one.  Some of the ID Cache interface was also
          rewritten and obsolete and stupid functions were removed.

Wed May 16 23:03:30 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added entry_count field to the SilcHashTable to keep the number
          of the entries in the table.  Implemented the function
          silc_hash_table_rehash.  Added new function
          silc_hash_table_count.  Affected file lib/silcutil/silchashtable.c.

          Fixed a minor bug in silc_hash_table_free.

        * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
          silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
          into the lib/silcutil/silcutil.[ch].

Wed May 16 20:02:47 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Implemented a collision resistant hash table into the
          lib/silcutil/silchashtable[ch].  See the header and the source
          for the SilcHashTable API.

Tue May 15 22:05:46 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Merged dotconf version 1.0.2 into lib/dotconf.

Sun May 13 19:32:09 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Do not compile anything in lib/silcsim/* if the SIM support
          is not enabled.  The tree should now compile without problems
          under cygwin.

Thu May 10 22:49:51 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Compiled the SILC under cygwin.  Compiled and tested briefly
          without problems.  More tests needed.  The SIMs didn't compile
          though.

        * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.

        * Fixed possible crash in silc_get_username in the
          lib/silcutil/silcutil.c.

Tue May  8 09:04:03 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed a va_arg in silc/client_ops.c.

        * Oops, RC5 routines were named AES and caused some problems
          when not using SIM's.  Affected file lib/silccrypt/rc5.c.

Sun May  6 13:59:48 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added new SilcIDIP structure into the lib/silccore/id.h and
          replaced the old `ip' fields from all SILC ID's to that type.
          This is a step towards IPv6 support.

          The silc_id_get_len takes now the ID as an extra argument.
          The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
          both IPv4 and IPv6 based ID's.

          The affected files are lib/silccore/id.[ch] and other files
          around the tree using these routines.

        * Removed the ID length arguments in server from various
          silc_server_send_notify_* routines -> they are not needed
          anymore.

Sat May  5 13:56:33 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed memory leak in silc_encode_pem_file in the file
          lib/silcutil/silcutil.c.

Thu May  3 21:23:50 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Check minor version as well in the SKE.  Affected files are
          silcd/protocol.c and lib/silcclient/protocol.c.

        * Added --identifier option to the server so that an identifier
          can be when creating the public key for the server.  Affected
          file is silcd/silcd.c.

        * Fixed minor decoding bug in silc_pkcs_decode_identifier in
          lib/silccrypt/silcpkcs.c.

Wed May  2 20:50:49 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Register default ciphers and stuff when using -C option with
          the server.  Affected file sildc/silcd.c.

        * Put back the servers public key filename format, it is better
          than the new one.  For now, the client keys are saved with the
          new filename format.  The affected file silc/client_ops.c.

        * Implemented the Cipher API for the rest of the ciphers that
          did not implement it or implemented it the wrong way.

Wed May  2 13:31:26 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Register default ciphers and stuff when using the -S option
          in the client.  Affected file silc/silc.c.  Same also when
          creating new key pair with -C option.

Tue May  1 14:18:13 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed the silc_verify_public_key client operation function to
          save the public keys differently.  The fingerprint is now
          used as filename and not the hostname.  This way also the
          client keys are saved uniquely and not with hostnames.  The
          affected file is silc/client_ops.c.

        * Trimmed the silc_hash_fingerprint function to remove extra
          whitespaces from the end of the fingerprint.  The affected
          file is lib/silccrypt/silchash.c.

        * Updated TODO.

        * Added silc_cipher_register_default function to register all
          default ciphers.  It can be used when configuration files
          does not exist and the application does not want any specific
          ciphers in any specific order.

          The SilcDList is now used as silc_cipher_list dynamically
          allocated cipher list.  Removed the static list all together
          and now all ciphers must be allocated to the dynamic list.
          The silc_cipher_alloc routine was changed to check only the
          dynamic list.

          All silc_cipher_* routines that used to return int returns
          now bool.

          The affected files lib/silccrypt/silccrypt.[ch].

        * The same thing was done to silc_hash_* as for silc_cipher_*
          routines.  Affected files lib/silccrypt/silchash.[ch].

        * The same thing was done to silc_pkcs_* as for silc_cipher_*
          routines.  Affected files lib/silccrypt/silcpkcs.[ch].
          Added also silc_pkcs_[un]register[_default] functions.
          Removed the data_context from the PKCS API.

        * Added silc_hmac_register_default function to register default
          hmacs.  Affected files lib/silccrypt/silchmac.[ch].  Added also
          SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
          to unregister all hmacs at once.

        * Register the default ciphers, hash functions, PKCSs and HMACs
          if client's configuration file does not exist.  The affected
          file silc/silc.c.

        * The client did not load the hash functions from the SIM
          modules at all.  Added support for this.  Affected file is
          silc/clientconfig.c.

        * When decoding public key with silc_pkcs_public_key_decode, check
          the supported algorithm only if PKCS are registered.  Affected
          file lib/silccrypt/silcpkcs.c.  The same was done with the
          silc_pkcs_private_key_decode.

        * Fixed the SILC List routines to keep the list always in order.
          It used to change the list's order when traversing the list but
          not it preserves the order.  Affected file lib/trq/silclist.h.

Mon Apr 30 17:29:03 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added the client library to use the SilcSocketConnection's
          reference counter (by silc_socket_dup) to prevent the bug that
          the socket object may be freed underneath async operation.

        * The name resolv library checking fixes in the configure.in.pre.
          The patch by salo.

        * Created new version of the protocol drafts for future
          development. The -03 drafts are the ones that will be changed
          in the trunk now and the -02 will remain as they are.

        * Send list of CUMODE notifys to the router when announcing
          the channel users to the router.  Affected file silcd/server.c.
          If the router receiving channel founder CUMODE for a channel
          that already has channel founder it will send CUMODE notify
          to the sender to remove the channel founder rights from the
          announced client.  Affected file silcd/packet_receive.c.

        * The CUMODE notify may now use Server ID as well as the entity
          who changes the mode.  Updated protocool specs.

        * Updated INSTALL and README files.

Sun Apr 29 23:17:50 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * New web pages in the http://silc.pspt.fi.  The pages was
          designed by salo.

        * Updated CREDITS.

Sun Apr 29 13:33:41 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Implemented the [DenyConnectin] config section in the server.
          Added silc_server_config_denied_conn to check whether incoming
          connection is denied.  Affected file silcd/serverconfig.[ch].

        * Do not check the ports when checking the incoming configuration
          data if the port is 0, meaning any.  Affected file is
          silcd/serverconfig.c.

Fri Apr 20 18:58:43 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed buffer overflow in silc_string_compare in the file
          lib/silcutil/silcutil.c.

        * Fixed double free in silc_server_command_leave in the file
          silcd/command.c.

Fri Apr 20 14:00:11 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed the version checking in the server.  Affected file is
          silcd/protocol.c.

Thu Apr 19 19:52:46 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed the configuration data fetching when accepting new
          connections in the server.  Affected file silcd/server.c.

Thu Apr 19 11:40:20 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added `sender_entry' argument to the function
          silc_server_packet_relay_to_channel so that we can check
          whether some destination actually belongs to the same route
          the sender belongs (ie, we must not resend the packet to the
          sender).  Affected file silcd/packet_send.[ch].

        * Added `servername' field to the SilcClientEntry in the server
          to hold the name of the server where client is from.  Affected
          file is silcd/idlist.h.

Wed Apr 18 22:19:03 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Moved the channel message encrypting in the router betwen
          router connections from silc_server_channel_message to the
          silc_server_packet_relay_to_channel since we want to check
          whether we have anybody channel before encrypting anything.
          Affected files silcd/packet_[receive/send].c.

Tue Apr 17 21:18:19 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed the [AdminConnection] server config section to support
          multiple entries.  Affected file silcd/serverconfig.c.

        * Added support into the server to check the validity of the
          incoming connection before executing any KE or authentication
          protocols.

        * The connection configuration is now saved to the KE and
          connection auth protocol contexts and not fetched anymore in
          the protocol.  Affected files silcd/server.c, silcd/protocol.[ch].

        * The local hosts listenning address and port is also resolved
          now when starting the server.  We want to have the socket object
          to include the real address and port for the listener.  Added
          new function silc_net_check_local_by_sock into the files
          lib/silcutil/silcnet.[ch].

        * Fixed a broadcast bug in server -> do not broadcast if we
          are standalone.

        * Fixed a routing bug.  Do not route broadcast packets ever.
          Broadcast packets must be processed always and not routed since
          they may be destined to some other host than yourself and thus
          would get routed without no good reason.  Affected file is
          silcd/server.c.

        * Added function silc_server_config_is_primary_route to check
          whether primary router connection has been configured (a router
          configuration that we are initiating).  If there is not, we
          will assume that there is only two routers in the SILC network
          and we will use the incoming router connection as our primary
          route.  Affected files silcd/serverconfig.[ch], silcd/server.c.

        * Changed the order of the broadcasting.  Broadcast _after_ the
          packet has been processed not before.  Affected file is
          silcd/server.c.

        * Fixed a [ClientConnection] parsing bug.  The port was never
          parsed correctly thus resulting to port 0.  Affected file
          silcd/serverconfig.c.

        * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
          argument and did not set the broadcast packet flag.  Affected
          file silcd/packet_send.c.  Fixed same bug in the function
          silc_server_send_notify as well.

        * If we receive NEW_ID packet for our own ID in the server, ignore
          the packet.

Mon Apr 16 12:10:33 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Updated TODO.

        * Removed the nickname from the Private Message Payload.
          Updated the code and the protocol specs.

        * Updated protocol specs for submitting to the IETF.

        * Tweaked the Random Number Generator a bit.  Affected file
          lib/silccrypt/silcrng.c.  Exported a new function
          silc_rng_[global]_add_noise which can be used to add more
          noise to the RNG.

Sat Apr 14 16:21:32 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Do not parse packets with different timeout when protocol
          is active -> may cause problem with rekey.  Affected file
          silcd/server.c.

        * When server receives signoff notify it must not create
          new channel key if the client is on any channels since the
          sender of the signoff notify will create it.

Fri Apr 13 17:12:46 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added printing of error messages during SKE protocol from the
          failure packet sent by server during SKE.  Affected file
          silc/client_ops.c.

        * Removed the client's failure_callback handling with timeout
          and handle it immediately when received.

        * The SKE library returned wrong type in SUCCESS and FAILURE
          packets.  They must be 32 bit MSB not 16 bit MSB.

Fri Apr 13 00:09:08 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Ok, rewrote the logic of the re-key and now it seems to work.
          I tested it on high traffic with frequent re-keys without
          problems.  Added hmac_receive (and renamed hmac to hmac_send)
          in SilcClientConnection in lib/silcclient/client.h and
          in SilcIDListData in silcd/idlist.h.  Also, removed the
          SilcPacketParserContext's cipher and hmac fields as they are
          not needed anymore and actually caused some problems when
          the ciphers and hmac's changed underneath the packet parser.

Thu Apr 12 14:42:51 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * If re-key protocol is active then process the incoming packets
          synchronously since we must assure that icoming packets encrypted
          with the old key is processed before the new keys is set to
          use.  This is true other packets than for REKEY packets.
          Affected file silcd/server.c.  The same was done to client library
          as well, affected file lib/silcclient/client.c.

Thu Apr 12 12:01:52 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed bug in client and server to accept the force send if
          the packet is send from silc_[server/client]_packet_process
          function.  Otherwise the packets are never delivered, oops.

Wed Apr 11 22:10:15 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Disable force sending of packets when REKEY protocol is active.
          We must assure that no packet is sent directly when rekey is
          performed.  All packets must be sent through packet queue.
          Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
          SILC_CLIENT_IS_REKEY to lib/silcclient/client.h.  Affected
          function is silc_[server/client]_packet_send_real to check
          the situation.

        * Replaced the SIM paths from example config files to
          /usr/local/modules.  Also, make install creates now
          /usr/local/silc/logs directory to hold all the SILC server
          logs.

Wed Apr 11 16:59:59 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Made the configure.in.pre work on Solaris.  Patch by salo.

        * Made all ciphers compatible with non-x86 machines.  Defined
          CBC mode macros into lib/silccrypt/ciphers_def.h.

Tue Apr 10 20:32:44 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed the make install.

Tue Apr 10 16:20:34 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * When MAC computation fails the silc_packet_decrypt returned 0
          even though it was supposed to return -1.  Fixed this.  The
          affected file is lib/silccore/silcpacket.c.

        * Do not replace the config files in /etc/silc (in make install)
          if they already exist.  Affected file ./Makefile.am.

        * Do not send re-key packets immediately but through packet queue.
          Affected file silcd/protocol.c and lib/silcclient/protocol.c.

        * Changed silc_net_check_host_by_sock to return FALSE if the
          IP/DNS could not be resolved.  Though, it returns the IP address
          now even if it could not resolve it (but returns also FALSE).
          Affected file lib/silcutil/silcnet.[ch].

Mon Apr  9 21:54:44 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added silc_pkcs_decode_identifier to decode the public key's
          identifier.  Affected file lib/silccrypt/silpkcs.[ch].
          Added also silc_pkcs_free_identifier.  Added also new context
          SilcPublicKeyIdentifier.

        * Added -S option to the silc client.  It is used to dump the
          contents of the specified public key file.

        * Changed the PKCS api to return the public key length when
          setting the public key.

        * Fixed a fatal bug in the public and private key file loading.
          Affected file lib/silccrypt/silcpkcs.c.

        * Execute the packet parsing for client with zero (0) timeout
          if the protocol is active.  Affected file silcd/server.c.

Sun Apr  8 19:30:56 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Made the key generation options to the silcd program.  Added
          -C option, equivalent to client's option.

        * Added new [ServerKeys] config section to the server.  It
          configures the server's public and private key.

        * Defined generic Public Key Payload into the protocol
          specification to send specific type of public keys and
          certificates.

        * Defined new command SILC_COMMAND_GETKEY to fetch a client's
          public key or certificate.

        * Implemented the GETKEY command to the server and to the
          client library and on user interface.

Sun Apr  8 01:37:21 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Made preliminary `make install' work.

Thu Apr  5 17:42:30 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added SilcServerRekey context into silcd/idlist.h.

        * Added the PFS support as defined in the specification to the
          SKE protocol.  Affected files lib/silcske/*.c.

        * Added `ske_group' field to the SilcServerRekey context to hold
          the number of the SKE group that is used with PFS in re-key.
          Affected file silcd/idlist.h.

        * Added PFS re-key support to the server.  Affected file is
          silcd/protocol.c.

        * Added silc_protocol_cancel to cancel execution of the next
          state of the protocol.  Affected file is
          lib/silccore/silcprotocol.[ch].

        * Added the re-key support with and without PFS to the client
          library.  Re-key is performed once in an hour, by default.

          Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
          Added silc_client_rekey_callback and silc_client_rekey_final.
          Affected files are lib/silcclient/protocol.[ch] and
          lib/silcclient/client.[ch].

        * Removed the `hmac_key' and `hmac_key_len' fields from the
          SilcClientConnection structure; not needed.  Affected file is
          lib/silcclient/client.h.

        * Updated TODO.

Wed Apr  4 16:32:31 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Do not ask whether user wants to use the negotiated private key
          for private messages, just use it.  Affected file is
          silc/local_command.c.

        * Added `send_enc_key' and `enc_key_len' fields to the
          SilcIDListData structure since they are needed in the re-key
          phase.  Affected file is silcd/idlist.[ch].

        * Implemented the simple re-key protocol into the server.
          Affected files silcd/server.c and silcd/protocol.[ch].  The
          re-key will be performed once in an hour, by default.

          Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
          Added silc_server_rekey, silc_server_rekey_callback and
          silc_server_rekey_final.

        * Removed Tunneled flag from the protocol.  Updated the code
          and the specifications.

        * Adde `pfs' field to the SilcIDListData to indicate whether
          the PFS is to be performed in the re-key.  Affected file is
          silcd/idlist.h.

Tue Apr  3 21:52:42 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
          int64 of at least the xintXX size.  If void * is less that 4
          bytes uint32 * will be used.  Defined bool as boolean.

        * Changed _ALL_ unsigned long and unsigned int to uint32,
          unsgined short to uint16 in the source tree.

        * Fixed a fatal bug in silc_server_remove_clients_by_server.  Do
          not handle clients that has entry->data.registered == FALSE.
          They are not in the network anymore.  Affected file is
          silcd/server.c.

Tue Apr  3 16:39:19 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Implemented the sending of the SERVER_SIGNOFF notify in the
          server.  Affected file is silcd/server.c.

        * Added silc_server_send_notify_args into silcd/packet_send.[ch].
          Added also silc_notify_payload_encode_args into the
          lib/silccore/silcnotify.[ch].

        * Implemented ther SERVER_SIGNOFF notify handling in the server.
          Affected file silcd/packet_receive.c.

        * Implemented the SERVER_SIGNOFF notify handling in the client
          library.  Affected file lib/silcclient/client_notify.c.  Also,
          implemnted the printing of the SERVER_SIGNOFF info to the
          application.  Affected file silc/client_ops.c.

        * The silc_idlist_del_server now returns TRUE or FALSE to indicate
          if the deleting was successful.  Affected file silcd/idlist.[ch].

        * Added support for public key authentication in the connection
          authentication protocol in the client library.  Affected file
          lib/silcclient/protocol.c.

        * Changed the server's silc_idlist_get_clients_by_* interface
          to support already allocated array so that new entries may be
          added to pre-allocated array.  Affected file silcd/idlist.[ch].
          This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
          and command replies.

        * All command reply functions in the server now calls the
          pending command callback even if error occured.  This way the
          error will be delivered to the client as well.  Affected files
          silcd/command.c and silcd/command_reply.c.

        * Fixed INFO command to return local server's info if no server
          was provided.  Affected file lib/silcclient/command.c.

        * Removed RESTART command for good.  Updated the code and the
          protocol specs.

        * Rewrote parts of the task system.  It is a bit simpler now.
          Removed unsued task priorities. The affected files are
          lib/silcutil/silctask.[ch].

Mon Apr  2 20:02:33 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Moved the USERS printing from the library to the application.
          Affected files lib/silcclient/command.c and silc/client_ops.c.

Mon Apr  2 13:13:23 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Updated TODO.

        * Added channel key re-key support.  The re-key is perfomed
          only by the router and is done once in an hour.  Added `rekey'
          field to the SilcChannelEntry in the server.  Affected files
          silcd/server.c and silcd/idlist.h.

        * Added silc_task_unregister_by_context into the file
          lib/silcutil/silctask.[ch].

Sun Apr  1 19:49:34 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added SILC_UMODE_GONE mode to indicate when the client is not
          present in the SILC network.  Added also support to the local
          command AWAY that will set this mode.  Added support of showing
          "xxx is gone" in WHOIS command.  The USERS command shows the
          gone status as well.

        * Fixed setting server and router operator privileges in the
          server's UMODE command.  Affected file silcd/command.c.

        * Merged the SKE KE1 and KE2 payloads into one payload.  The
          new KE payload is equivalent to the old KE2 payload.

          Cleaned up the SKE Start Payload parsing.  It now uses the
          simple buffer unformatting to do the parsing.  A lot faster
          now.

          Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
          to the SKE that is used to indicate whether both of the SKE
          parties should perform authentication.  By default only the
          responder performs authentication.  By setting this flag also
          the initiator must do authentication.  By default it is unset
          since in normal SKE case, client to server connection, only
          the responder should do authentication.  When doing SKE between
          two clients both should perform authentication.  Updated the
          code and the protocol specs.

        * A little fix to IDENTIFY command in the server.  Search the
          client first by hash not nickname.  Affected file is
          silcd/command.c.

        * Fixed the silc_client_close_connection to support closing
          the client to client connections wihtout deleting too much
          data.  Affected file lib/silcclient/client.c.

        * Fixed a fatal bug in server and client; if KE1 or KE2 packets
          are received if protocol used to be active but is not anymore
          the application would crash due to NULL pointer dereference.
          Affected files silcd/server.c and lib/silcclient/client.c.

        * Added `hash' field to the SilcClientConnection to include
          the hash function negotiated in the SKE protocol.

        * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
          to set the channel founder authentication data.  A client can
          claim the founder rights later by providing the authentication
          data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
          This way the channel founder can regain the channel founder
          privileges even it is left the channel.  This works only on
          local server and the client must be connected to the same
          server to be able to regain the founder rights.  Updated the
          protocol specs accordingly.

          Added support to the CMODE command in the client to set the
          founder auth data.  Read the README to see how to set it.

          Added support to the CUMODE command to claim the founder
          rights.  Read the README to see how to do it.

          Added support for the founder authentication to the Channel
          Entry in the server.  Affected file silcd/idlist.h.

          Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
          server's CMODE command.  Affected file silcd/command.c.

        * Added the following new functions into lib/silccore/silcauth.[ch]:
          silc_auth_get_method and silc_auth_get_data.

        * The server now saves the remote hosts public key to the
          SilcIDListData pointer.  Affected file silcd/protocol.c.

        * The normal server now does not remove the channel entry from
          the cache if the founder authentication data is set.  It used
          to remove it if the founder was the last one on the channel on
          the server and left the channel.  The auth data is saved and
          if the channel is re-joined later the old entry is used with
          the old auth data.  Affected files silcd/command_reply.c and
          silcd/server.c.

        * Removed the `pkcs' field from the SilcIDListData structure
          in the server; it is not used.  Affected file silcd/idlist.h.

Sat Mar 31 15:38:36 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed packet processing on slow links.  Partial packets were
          never re-processed because the incoming data buffer was cleared
          by the application.  Application must not directly clear the
          sock->inbuf, the packet processing routines handle it.  Fixed
          this in client library and in server.

Fri Mar 30 16:35:27 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed the WHOIS and IDENTIFY send reply function to really
          check whether to send list or just one entry.  Affected file
          silcd/command.c.

        * Cleaned up the LEAVE command's channel key distribution.  The
          affected file silcd/command.c.

        * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
          can enforce the channel mode as well.  In that case the ID
          includes the ID of the server.  The code now enforces the
          mode change if the router have different mode than the server.

        * The notify client operation with CMODE_CHANGE notify can now
          return NULL client_entry pointer if the CMODE was not changed
          by client.  Application must check for this.

        * Added <Server ID> argument to INFO command to support server
          info fetching by Server ID.

        * Added silc_server_announce_get_channel_users to get assembled
          packets of channel users of the specified channel.  Affected
          file silcd/server.[ch].

        * Fixed bug in CHANNEL_CHANGE notify in the server.  The new ID
          was freed underneath the ID Cache.

        * Re-announce clients when the server received CHANNEL_CHANGE
          notify from the router.  Affected file silcd/packet_send.c.

Thu Mar 29 19:10:28 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
          crashed since it did not handle the fact that there is no cipher
          called "3" and didn't check the error condition.  Now fixed.

        * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
          flag.  It can be used to send message requests.

Thu Mar 29 12:26:25 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Implemented the RESTART command in the client.

        * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
          notice type messages.  Added notice printing to the user
          interface.

        * The channel keys are not re-generated if the channel's mode
          is PRIVKEY, ie private key on the channel exists.  Affected
          files silcd/server.c and silcd/command.c.

        * Fixed a little bug in channel message delivery when channel
          private keys are set in the server.  Affected file is
          silcd/packet_send.c.

        * Changed the setting on channel->on_channel = TRUE from the
          silc_client_save_channel_key to the JOIN command reply.  The
          key payload is not received if the private channel key is set.
          Affected file lib/silcclient/command_reply.c and the
          lib/silcclient/client_channel.c.

        * When the CMODE_CHANGE notify is sent and the channel private
          key mode is removed the channel key must be re-generated in
          other cells as well.  Added this support for the router in the
          silcd/packet_receive.c.

        * Added new local command NOTICE to send notice message on
          channel.  Affected file silc/local_command.[ch].

Wed Mar 28 23:55:54 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added new local command ME to the client.  It is used to send
          message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
          some action.  Affected file silc/local_command.[ch].

        * Changed channel_message and private_message client operations
          to deliver the message flags to the application.  Added also
          the `flags' arguments to the silc_client_send_channel_message
          and silc_client_send_private_message functions.  Affected file
          silcapi.h.

Wed Mar 28 20:50:47 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Redefined the Private Message Payload to support private message
          keys and to support the new private message flags.  Updated
          the protocol specs.  Flags makes it possible to have for example
          CTCP style messages.

        * Added new type SilcPrivateMessagePayload and defined an API
          for it in the lib/silcclient/silcprivate.[ch].

        * Tested private message private keys successfully.  Tested the
          private message key set, unset and list commands with the new
          KEY command.

        * Redefined the Channel Message Payload to include the channel
          message flags (equal with private message flags) to support
          for example CTCP style messages.

        * Defined some of the message (for channel and private message)
          flags.  Updated the protocol specs and added the flags to the
          lib/silccore/silcchannel.h.  The type is SilcMessageFlags.

Wed Mar 28 15:52:36 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added SilcKeyAgreementStatus type to the key agreement routines
          to indicate the current status and error if one occured.
          The status types are defined in the lib/silcclient/silcapi.h.

        * Added new local command KEY that is used to set and unset private
          keys for channels, set and unset private keys for private messages
          with remote clients and to send key agreement requests and
          negotiate the key agreement protocol with remote client.  The
          key agreement is supported only to negotiate private message keys,
          it currently cannot be used to negotiate private keys for channels,
          as it is not convenient for that purpose.

        * Fixed a minor pending callback setting bug in the function
          silc_client_get_client_by_id_resolve, now the function works.
          Affected file lib/silcclient/idlist.c.

        * Added function silc_net_get_local_port to get local bound
          port by socket.  Added to lib/silcutil/silcnet.[ch].

        * Added `sockets' and `sockets_count' fields to the SilcClient
          object.  They hold the sockets of the listenning sockets in
          the client.  Listenning sockets may be for example the key
          agreement server.  Affected file lib/silcclient/client.[ch].
          Added functions the silc_client_add_socket and the
          silc_client_del_socket.  They are exported to the application
          as well.

        * Added ~./silc/clientkeys to support other client's public keys.

        * Renamed verify_server_key client operation to verify_public_key
          and added one argument to indicate the type of the connection
          (server, client etc.).

Tue Mar 27 22:22:38 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added silc_server_connection_auth_request to handle the
          incoming CONNECTION_AUTH_REQUEST packet.  Affected file is
          silcd/packet_receive.[ch].

        * Added silc_server_send_connection_auth_request into the
          silcd/packet_send.c to send the connection auth request packet.

        * Cleaned up the silcd/protocol.c a bit and fixed some memory
          leaks.

        * Fixed the public key authentication in responder side in the
          server.  The `auth_data' pointer includes the SilcPublicKey
          not the path to the public key.  Affected file silcd/protocol.c.

        * Implemented the public key authentication in the initiator side
          in the server.  Affected file silcd/protocol.c.

        * Removed the [RedirectClient] config section from the server
          configuration.  Is not needed and I don't want to implement it.

Tue Mar 27 12:49:56 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Cleaned up the CMODE command in the server.  It now works
          correctly and supports all the modes defined in the protocol.
          Affected file is silcd/command.c.

        * Added `hmac_name' field to the SilcChannelEntry in the server
          to hold the default HMAC of the channel.  It can be set when
          creating the channel (with JOIN command).  Affected files
          silcd/idlist.[ch].

        * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
          type to indicate the change of the current cipher and hmac
          on the channel.  Client can safely ignore the <cipher> argument
          (if it chooses to do so) since the CHANNEL_KEY packet will
          force the channel key change anyway.  The <hmac> argument is
          important since the client is responsible of setting the new
          HMAC and the hmac key into use.

        * Fixed the CMODE command in the client library as well.

        * Tested CMODE command in router environment successfully.

Mon Mar 26 14:39:48 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Show the version of the remote client (or server) when connecting
          to the server.  It is logged to the log file.  Affected file
          is silcd/protocol.c.

        * Fixed the KILLED notify handling in the client library.  The
          client must be removed from all channels when receiving the
          KILLED notify.

          Also, do not remove the client entry when giving the KILL
          command but when the KILLED notify is received.

        * Removed silc_idlist_find_client_by_nickname from the server.
          Not needed anymore.  Affected files silcd/idlist.[ch].

        * Implemented the CHANNEL_CHANGE notify type handling to the
          server.  Affected file silcd/server.c.

        * Updated TODO.

Mon Mar 26 12:11:14 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added silc_server_send_notify_invite to send the INVITE
          notify between routers.

        * Implemented the INVITE command correctly to the server.

        * Implemented the INVITE notify type handling in the server.

        * Implemented the INVITE command to the client library and on the
          user interface.

Sun Mar 25 20:27:09 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added function silc_server_get_client_resolve to find the
          client entry by ID from all ID lists and then resolve it
          (using WHOIS) if it cannot be found.  Affected file is
          silcd/server.[ch].

Sun Mar 25 13:52:51 EEST 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Implemented the BAN command to the client library.

        * The JOIN command in the server now checks the invite list
          and the ban list.

        * Changed the silc_command_reply_payload_encode_va and the
          silc_command_payload_encode_va to support that if argument is
          NULL it ignores and checks the next argument.  Affected file
          lib/silccore/silccommand.c.

        * Added silc_server_send_notify_ban to send the BAN notify
          type between routers.

        * Chaned the silc_notify_payload_encode to support that if
          argument is NULL it ignores and checks the next argument.
          Affected file lib/silccore/silcnotify.c.

        * Tested ban lists in router environment successfully.

Sat Mar 24 14:47:25 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Implemented BAN command to the server, in silcd/command.[ch].

        * Removed the BAN and INVITE_LIST modes from the CMODE command
          in the server code.

        * Added function silc_string_match to regex match two strings.
          Affected files lib/silcutil/silcutil.[ch].

Fri Mar 23 22:02:40 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Redefined parts of the SilcChannelEntry in the server to support
          the new ban and invite lists.

Fri Mar 23 16:25:11 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Redefined the INVITE command.  The same command can be used to
          invite individuals to the channel but also to manage the invite
          list of the channel (to add to and remove from the invite list).
          Updated the protocol specs.

        * Added new command SILC_COMMAND_BAN that can be used to manage
          the ban list of the channel.  Updated the protocol specs.

        * Removed the channel modes: the SILC_CMODE_BAN and the
          SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
          in the CMODE command.  The equivalent features are now available
          using INVITE and BAN commands.  Updated the protocol specs.

        * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
          in the network about change in the current ban list.  The notify
          type is not used by the client.

        * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
          support the invite lists.

Thu Mar 22 22:52:23 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added new function silc_string_regexify that converts string
          including wildcard characters into regex string that can
          be used by the GNU regex library.  Added into the file
          lib/silcutil/silcutil.[ch].

          Added silc_string_regex_combine to combine to regex strings
          into one so that they can be used as one regex string by
          the GNU regex library.  Added into the file
          lib/silcutil/silcutil.[ch].

          Added silc_string_regex_match to match two strings.  It returns
          TRUE if the strings match.  Added into lib/silcutil/silcutil.[ch].

Thu Mar 22 15:29:42 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Imported GNU regex to the soruce tree into lib/contrib.
          Fixed some compiler warning from the regex.c.

Wed Mar 21 15:27:58 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed MOTD command in the server to work in router environment.

        * Fixed the MOTD command in the client library to support
          the server argument in the command.

        * Added `nickname_len' argument to the silc_idlist_add_client
          in the server, as the `nickname' argument may be binary data
          (it may be hash).

        * Added silc_idlist_get_channels to return all channels from
          the ID list.

        * Implemented LIST command to the server.  Affected file is
          silcd/command.c.

        * Implemented the LIST command to the client library and on the
          user interface.

        * Added [<user count>] argument to the LIST command reply.
          With private channels the user count is not shown.

        * Updated TODO and README.

Tue Mar 20 21:05:57 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * The client entry's data.registered must be TRUE even with
          global client entry on global client list.  The data.registered
          is used to check whether the client is anymore in the network,
          for example with WHOWAS command so it must be valid.

        * Fixed the WHOWAS command in the server.  It now actually works
          in router environment.  Added function into silcd/command_reply.c
          silc_server_command_reply_whowas_save.

        * Added silc_idlist_purge function to the silcd/idlist.c
          to periodically purge the ID Cache.

        * Fixed INFO command in the server.  It works now in router
          environment.  Added <server name> argument to the INFO command
          reply.  Updated the protocol specs.

        * Fixed minor bug in silc_idcache_purge to not purge if the
          expire value is zero.

        * Fixed various bugs in WHOIS and IDENTIFY command handling as
          they were buggy because of the WHOWAS information.

        * Fixed local command MSG to handle the async resolving of
          the remote client properly.  It used to fail the first MSG.
          Affected file silc/local_command.c.

        * Added `data_len' field to SilcIDCache context.

Tue Mar 20 16:29:00 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Update TODO.  Todo in commands in the server.

Tue Mar 20 15:45:14 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
          used by routers as broadcast packet to inform other routers
          about the changed user mode.

          Implemented the notify handling in the server.  Affected file is
          silcd/packet_receive.c.  Added the function
          silc_server_send_notify_umode to the silcd/packet_send.[ch].

        * Added new generic Channel Payload and deprecated the New Channel
          Payload.  The New Channel Payload is now the generic Channel
          Payload.

        * Added new argument `mode' to the silc_server_send_new_channel
          as it is required in the Channel Payload now.

        * Renamed the SilcChannelPayload to SilcChannelMessagePayload
          and created a new and real SilChannelPayload to represent the
          new generic Channel Payload.  Implemented the encode/decode
          for Channel Payload.  Affected file lib/silccore/silcchannel.[ch].

        * Added silc_server_get_client_channel_list to return the list
          of channels the client has joined for WHOIS command reply.
          Affected file silcd/server.[ch].

        * Implemented the channel list sending in the WHOIS command reply
          in server and in the client.

          Implemented the channel list displaying on the user interface
          as well.  Affected file silc/client_ops.c.

        * Added silc_channel_payload_parse_list to parse list of Channel
          Payloads.  It returns SilcDList list of SilcChannelPayloads.
          Client for example can use this function to parse the list of
          channels it receives in the WHOIS command reply.  The caller
          must free the list by calling silc_channel_payload_list_free.
          Affected files lib/silccore/silcchannel.[ch].

Mon Mar 19 21:39:15 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added one new argument <user mode> to the WHOIS command reply
          to return the mode of the user in SILC.  Updated the protocol
          specs.

          Implemented it to the server and client.

Mon Mar 19 18:43:06 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed the mode printing on the user interface on joining.
          Affected file silc/client_ops.c.

        * Implemented the UMODE command and user modes in general to the
          client library and to the user interface.

        * Implemented the UMODE command to the server.

        * The server now sends UNKNOWN_COMMAND error status if client sends
          unknown command.  Affected file silcd/command.c.

        * All server commands now handle the command identifier the right
          way when sending the command reply to the client.  The client can
          use to identify the command replies with the identifier.

Mon Mar 19 16:13:07 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added silc_server_get_client_route to resolve the route to
          the client indicated by the client ID.  Affected file is
          silcd/server.[ch].

        * Added silc_server_relay_packet as general function to relay
          packet to arbitrary destination.  This deprecates functions
          like _send_private_message_key, _relay_notify etc.  Affected
          file is silcd/packet_send.[ch].

          Removed silc_server_send_key_agreement,
          silc_server_send_private_message_key and
          silc_server_packet_relay_notify functions from the file
          silcd/packet_send.[ch].

        * Updated TODO.

        * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
          server.  Affected file silcd/packet_receive.[ch].

        * Implemented the KILL command to the client.  Implemented the
          SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
          Affected files lib/silcclient/command[_reply].c and
          lib/silcclient/client_notify.c.  Implemented the KILL notify
          printing in the user inteface.

        * Fixed a lot silc_parse_nick memory leaks from the client
          library in the file lib/silcclient/command.c.

        * Changed the silc_server_send_notify_on_channels's `sender'
          argument from SilcSocketConnection to SilcClientEntry to
          check the sender as entry and not as connection object and not
          to send to the client provided as argument.  The affected file
          is silcd/packet_send.[ch].

        * The notify packets that are destined directly to the client used
          to not to be processed by the server.  Now changed that and the
          server processes all notify packets.  After relaying the packet
          to the client the notify packet is processed in the server.

        * The silc_server_free_client_data now checks whether there is
          pending outgoing traffic for the client and purges the data to
          the network before removing the client entry.

Sun Mar 18 21:02:47 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added SILC_NOTIFY_TYPE_KILLED notify type.  It is sent when
          an client is killed from the SILC Network.  Updated the protocol
          specs accordingly.

          Added new function silc_server_send_notify_killed to the
          silcd/packet_send.[ch].

        * Added function silc_server_packet_relay_notify to relay notify
          packets that are destined directly to a client.  In this case
          the server does not process the notify packets but merely relays
          it to the client.  Affected file silcd/packet_send.[ch].

          Added also silc_server_packet_process_relay_notify to check
          whereto relay the notify.  Affected file is
          silcd/packet_receive.[ch].

        * Implemented the KILL command to the server.

        * Updated TODO.

        * Added the backup schema desgined last fall to the protocol
          specs for everyone to see.  The specification is in the
          *-spec-xx.txt draft and the packet type definitions for the
          backup routers is in *-pp-xx.txt draft.  Thusly, added also
          new packet type SILC_PACKET_CELL_ROUTERS.

        * A big security problem in the implementation discovered.  The
          signoff of an client did not cause new channel key generation
          which it of course should've done.  The channel keys must be
          always re-generated when client leaves (or signoffs) the channel.
          The silc_server_remove_from_channels funtion now handles
          the channel key re-generation.

        * Added `sender' argument to the silc_server_send_notify_on_channels
          to not to send the client provided as argument.  Affected file
          silcd/packet_send.[ch].

Fri Mar 16 15:52:49 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Implemented OPER and SILCOPER commands into the server and
          the client library.

        * Added silc_auth_verify and silc_auth_verify_data to verify
          the authentication directly from the authentication payload.
          It supports verifying both passphrase and public key based
          authentication.  Affected file lib/silccore/silcauth.[ch].

        * Added `hash' field to the SilcIDListData structure.  It is the
          hash negotiated in the SKE protocol.  Affected file is
          silcd/idlist.[ch].

        * Slight redesigning of the SilcAuthPayload handling routines.
          Do not send SilcPKCS but SilcPublicKey as argument.

        * Implemented the public key authentication support to the
          serverconfig.  The public key is loaded from the provided path
          and saved as authentication data to void * pointer.  Thus,
          changed the unsigned char *auth_data to void *auth_data;

        * Fixed SHUTDOWN command to send the reply before the server
          is shutdown. :)  Affected file silcd/command.c.

        * Fixed fatal bug in CONNECT command.  The hostname was invalid
          memory and server crashed.  Affected file silcd/command.c.

        * Fixed fatal bug in CLOSE command.  The server_entry became
          invalid but was referenced later in the command.  Affected file
          silcd/command.c.

Thu Mar 15 12:46:58 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed fatal bug in failure packet handling.  Server ignored
          the failure and thus crashed when it came.

        * Updated TODO.

Wed Mar 14 20:37:35 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added new SILC_CF_LAG_STRICT command flag that strictly forces
          that the command may be executed only once in (about) 2 seconds.
          The old SILC_CF_LAG flag is same but allows command bursts up
          to five before limiting.

          Added the support for CF_LAG and CF_LAG_STRICT flags to the
          server code.  Various commands now includes the CF_LAG_STRICT
          flag to disallow any kind of miss-use of the command.

        * Fixed the silc_buffer_unformat to not to allocate any data
          if the length of the data is zero.  It used to allocate the
          length + 1.  Affected file lib/silcutil/silcbuffmt.c.

Wed Mar 14 16:10:30 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Changed the format of AdminConnection configuration section
          in the server.  Added username of the admin to the format.
          Affected files silcd/serverconfig.[ch].

          Added silc_server_config_find_admin into silcd/serverconfig.[ch]
          to return admin configuration data by host, username and/or
          nickname.

Wed Mar 14 13:18:16 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Implemented WHOWAS command to the server.  Added the functions:

          silc_server_command_whowas_parse,
          silc_server_command_whowas_send_reply,
          silc_server_command_whowas_from_client and
          silc_server_command_whowas_from_server

        * Added <Client ID> argument to the WHOWAS command reply.  Updated
          the protocol specs accordingly.

        * Implemented WHOWAS command and command_reply to the client
          library.

          Implemented the WHOWAS printing on the user interface.

Tue Mar 13 22:17:34 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added new argument to the WHOWAS command reply, the real name.
          It is an optional argument.  Updated the protocol specs.

        * Added SilcIDCacheDestructor callback that is registered when
          the SilcIDCache is allocated.  The callback is called when
          an cache entry in the ID Cache expires, or is purged from the
          cache.  Added into lib/silccore/idcache.[ch].

          Added silc_idlist_client_destructor to the silcd/idlist.[ch]
          to destruct the client entries when the cache entry expires.
          Other ID Cache's in server and in the client library ignores
          the destructor.

        * If the ID Cache entry's `expire' field is zero then the entry
          never expires.  Added boolean `expire' argument to the
          silc_idcache_add function in the lib/silccore/idcache.[ch].
          If it is TRUE the default expiry value is used.

        * Added silc_server_free_client_data_timeout that is registered
          when client disconnects.  By default for 5 minutes we preserve
          the client entry for history - for WHOWAS command.

Tue Mar 13 13:26:18 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added support to the server to enforce that commands are not
          executed more than once in 2 seconds.  If server receives
          commands from client more frequently, timeout is registered
          to process the commands.  Affected file silcd/command.c.
          Added new function silc_server_command_process_timeout.

        * Changed NICK_NOTIFY handling in client library to check that
          if the client's nickname was changed, so there is no need to
          resolve anything from the server.

        * Removed error printing from the WHOIS and IDENTIFY commands.
          If error occurs then it is ignored silently in the client library.
          The application, however, may map the received error to
          human readable error string.  The application currently maps
          the NO_SUCH_NICKNAME error to string.

        * Made the command status message public to the application.  Moved
          them from lib/silcclient/command_reply.c to
          lib/silcclient/command_reply.h.  The application can map the
          received command status to the string with the
          silc_client_command_status_message function.

        * Added check to the server to check that client's ID is same
          as the Source ID in the packet the client sent.  They must
          match.

Tue Mar 13 12:49:21 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added dist-bzip hook to the Makefile.am to make bzip2
          compressed distributions.

Mon Mar 12 18:43:38 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Server now enforces the maximum length for the nickname and
          the channel as protocol specification dictates.  128 bytes for
          nickname and 256 bytes for channel name.

        * Moved the WHOIS printing to the application.  The client libary
          does not print out the WHOIS information anymore, the application
          must do it.  Renamed silc_client_command_reply_whois_print to
          the silc_client_command_reply_whois_save.

          The client's idle time is also sent to the application now, and
          the idle is shown on screen.

        * Added silc_client_command_reply_identify_save to save the
          received IDENTIFY entries.

        * Do not check for channel private keys in message sending and
          reception if the channel does not have the PRIVKEY mode set.
          Affected file lib/silclient/client_channel.c.

Sun Mar 11 20:25:06 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
          just surfaced after chaning the JOIN procedure.

Sun Mar 11 14:59:05 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added silc_client_get_clients_by_list to get client entries
          from Client ID list, that is returned for example by JOIN
          and USERS command replies.  The application should use this
          function for example when JOIN command reply is received to
          resolve the clients already on the channel (library does not
          do that anymore as USERS command reply is not used in the JOIN
          procedure anymore).  Affected files lib/silcclient/silcapi.h and
          lib/silcclient/idlist.c.

        * JOIN command reply and USERS command reply returns now SilcBuffer
          pointers instead of unsigned char pointers when returning
          the client list and mode list.

        * Added <Client ID> argument to the JOIN command reply, mainly
          for the server to identify for which client the command was
          originally sent.  Updated protocol specs accordingly.

        * Added SilcDlist private_key pointer to the SilcChannelEntry
          in the client to support the channel private keys.  Affected
          file is lib/silcclient/idlist.h.

        * Added SilcChannelPrivateKey argument to the function
          silc_client_send_channel_message so that application can choose
          to use specific private ke if it wants to.  If it is not provided,
          the normal channel key is used, unless private keys are set.
          In this case the first (key that was added first) is used
          as the encryption key.

        * Implemented the support for channel private key handling.
          Implemented the following functions:

          silc_client_add_channel_private_key,
          silc_client_del_channel_private_keys,
          silc_client_del_channel_private_key,
          silc_client_list_channel_private_keys and
          silc_client_free_channel_private_keys

          Affected file lib/silcclient/client_channel.c.

        * Added the support for the private keys in the channel message
          sending and encryption and in the message reception and
          decryption.  Affected funtions are
          silc_client_send_channel_message and silc_client_channel_message.

Sat Mar 10 21:36:22 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added SKE's key verify callback to the client library's
          KE protocol context. Affected files lib/silcclient/protocol.[ch].

        * Removed the statement that server (or router) must send USERS
          command reply when joining to the channel so that the client
          knows who are on the channel.  Instead, the client list and
          client's mode list is now sent in the JOIN command reply to the
          client who joined channel.  This is better solution.

        * Added function silc_server_get_users_on_channel and function
          silc_server_save_users_on_channel to the silcd/server.[ch].

        * Removed function silc_server_command_send_users from the
          silcd/command.c.

        * Do not show topic on the client library anymore.  The topic is
          sent in the command reply notify to the application and the
          application must show the topic now.

Sat Mar 10 00:07:37 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added client searching by nickname hash into the IDENTIFY and
          WHOIS commands in the server as they were clearly missing from
          them.  Affected file is silcd/command.c.

        * Fixed a bug in private message receiving in the client library.
          The remote ID was freed and it wasn't supposed, now it is
          duplicated.

Fri Mar  9 12:40:42 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Minor fix to the channel payload; allocate the data area, as it
          needs to be of specific length.

        * If the key agreement port is zero then the operating
          system will define the bound port.  Affected files are
          lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.

        * Added new function silc_channel_payload_decrypt into the file
          lib/silccore/silcchannel.[ch].

        * Moved the channel message etc, check from silc_packet_decrypt
          to applications.  The library calls now a generic
          SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
          when the packet is either normal or special.  This was done to
          allow more wide range of checking that was not allowed when
          the code was in library.  Now applications can do virtually any
          checks to the packet and return to the library the decision how
          the packet should be processed.  Affected files are
          lib/silccore/silcpacket.[ch].

          Added silc_server_packet_decrypt_check to the server and
          silc_client_packet_decrypt_check to the client library.

        * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
          to send with specified source and destination information.

        * Channel message delivery between routers was broken after the
          channel key distribution was fixed earlier.  The channel key
          was used be to distributed to other routers as well which is not
          allowed by the protocol.  Now this is fixed and channel keys
          really are cell specific and the channel message delivery between
          routers comply with the protocol specification.

        * Fixed various commands in server to check also the global list
          for the channel entry and not just the local list.  The affected
          file silcd/command.c.

Thu Mar  8 21:39:03 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added assert()s to buffer formatting and unformatting routines
          to assert (if --enable-debug) when error occurs.  Affected
          file: lib/silcutil/silcbuffmt.c.

        * Changed to auto-reconnect to check whether the remote host is
          router and register the re-connect timeout if it is.  It used
          to check that whether we are normal server, but router must do
          auto-reconnect with another router as well.  Affected file
          silcd/server.c.

        * Removed the [<key len>] option from CMODE command as the cipher
          name decides the key length, nowadays.  See the defined ciphers
          from the protocol specification.

        * Added [<hmac>] option to the CMODE command to define the HMAC
          for the channel.  Added SILC_CMODE_HMAC channel mode.

        * Added [<hmac>] option for the JOIN command so that user can
          select which HMAC is used to compute the MACs of the channel
          messages.

        * Added Hmac field to the Channel Message Payload.  The integrity
          of plaintext channel messages are now protected by computing
          MAC of the message and attaching the MAC to the payload.  The
          MAC is encrypted.  Now, it is clear that this causes some
          overhead to the size of the packet but rationale for this is that
          now the receiver can verify whether the channel message decrypted
          correctly and also when private keys are set for the channel the
          receiver can decrypt the packet with several keys and check from
          the MAC which key decrypted the message correctly.

        * Added silc_cipher_encrypt and silc_cipher_decrypt into the
          lib/silccrypt/silccipher.[ch].

        * Added silc_hash_len to return the digest length into the
          lib/silcrypt/silchash.[ch].

        * Rewrote parts of Silc Channel Payload interface in the
          lib/silccore/silcchannel.[ch].  The encode function now also
          encrypts the packet and parse function decrypts it.

Wed Mar  7 20:58:50 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed a minor formatting bug in the SKE's key material processing.
          It actually might have processed the keys wrong way resulting
          into wrong keys.

        * Redefined the mandatory HMAC algorithms and added new algorithms.
          Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
          and hmac-md5 truncated to 96 bits.  The mandatory is now
          hmac-sha1-96.  Rest are optional (including the one that used
          to be mandatory).  Rationale for this is that the truncated HMAC
          length is sufficient from security point of view and can actually
          make the attack against the HMAC harder.  Also, the truncated
          HMAC causes less overhead to the packets.  See the RFC2104 for
          more information.

        * Added new [hmac] configuration section.  The SKE used to use
          the hash names (md5 and sha1) in the SKE proposal as HMCAS which
          is of course wrong.  The official names that must be proposed in
          the SKE are the ones defined in the protocol specification
          (hmac-sha1-96 for example).  The user can configure any hmac
          using any hash function configured in the [hash] section.  At
          least, the mandatory must be configured.

          Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].

        * Added HMAC list to the SKE proposal list.  It has now both
          hash algorithm list and HMAC list.  This makes the protocol
          incompatible with previous versions.  The SKE now seems to work
          the way it is supposed to work, for the first time actually.

        * Defined plain Hash algorithms to the protocol specification.
          Added sha1 and md5.

Tue Mar  6 15:36:11 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Implemented support for key agreement packets into the server.
          Added functions silc_server_key_agreement and
          silc_server_send_key_agreement.  Other than these functions,
          server has nothing to do with this packet.

        * Added support for private message key packets into the server.
          Added functions silc_server_private_message_key and
          silc_server_send_private_message_key.

        * Updated TODO.

        * Changed the silc_[client|server]_protocol_ke_set_keys to be
          called in the protocol's final callback instead in the END
          protocol state.  This makes a little more sense and in the same
          time in client we can use the same protocol routines for normal
          key exchange and to key agreement packet handling as well.

        * Added to both client's and server's KE protocol context the
          SilcSKEKeyMaterial pointer to save the key material.  We will
          bring the key material to the protocol's final callback by doing
          this.  The final callback must free the key material.

        * Added SKE's packet_send callback into client's KE protocol
          context so that the caller can choose what packet sending function
          is used.  This way we can use different packet sending when
          doing normal SKE when doing key agreement packet handling (in
          the key agreement packet handling we do not want to encrypt
          the packets).

        * Implemented the responder side of the key agreement routines
          in the client.  The client can now bind to specified port and
          accept incoming key negotiation.  The key material is passed
          to the application after the protocol is over.

        * Implemented the processing of incoming Key Agreement packet
          in the client.  Added function silc_client_key_agreement to
          process the packet.

        * Implemented the intiator side of the key agreement routines
          in the client.  The client can now initiate key agreement with
          another remote client.  The key material is passed to the
          application after the protocol is over.

        * Created client_keyagr.c to include all the key agreement
          routines.

        * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
          SILC_TASK_CALLBACK except that it is not static.

        * Created client_notify.c and moved the Notify packet handling
          from the client.[ch] into that file.

        * Created client_prvmsg.c and moved all private message and
          private message key routines from the client.[ch] into that file.

        * Create client_channel.c and moved all channel message and
          channel private key routines from the client.[ch] into that file.

        * Changed silc_client_get_client_by_id_resolve to resolve with
          WHOIS command instead of IDENTIFY command, in the file
          lib/silclient/idlist.c.

Mon Mar  5 18:39:49 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Implemented the SKE's responder side to the Client library.

        * When FAILURE is received to the protocol do not trust it
          blindly.  Register a timeout to wait whether the remote closes
          the connection as it should do it, only after that process the
          actual failure.  This was changed to both client and server.

        * Added client_internal.h to include some of the structures
          there instead of client.h in lib/silcclient/.

        * Added function silc_task_unregister_by_callback to unregister
          timeouts by the callback function.

Sat Mar  3 19:15:43 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Some "Incomplete WHOIS info" errors has been appearing on the
          log files.  Took away the entry->userinfo check from WHOIS
          reply sending.  The entry->userinfo is now " " if client did not
          provide one.  I thought this was fixed earlier but something
          is wrong still.  Let's see if the error still appears.

Wed Feb 28 20:56:29 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed a minor bug in the login when the channel key is
          re-generated in the server.  It used to generate the key in
          wrong order and thus caused problems in the channel traffic.

        * Fixed a minor bug in channel key distsribution after
          KICK command.  The key was not sent to the router even though
          it should've been.

Tue Feb 27 20:24:25 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added silc_ske_process_key_material_data as generic routine
          to process any key material as the SILC protocol dictates.  The
          function is used by the actual SKE library but can be used by
          applications as well.  This relates to the private message keys
          and the channel private keys since they must be processed the
          same way the normal SILC session keys.  The protocol dictates
          this.  Affected files: lib/silcske/silcske.[ch].

          Added also silc_ske_free_key_material to free the
          SilcSKEKeyMaterial structure.

        * Defined silc_cipher_set_key function to set the key for
          cipher without using the object's method function.  The affected
          files: lib/silccrypt/silccipher.[ch].

        * Implemented silc silc_client_add_private_message_key,
          silc_client_add_private_message_key_ske,
          silc_client_del_private_message_key,
          silc_client_list_private_message_keys and
          silc_client_free_private_message_keys functions in the
          client library.

          Added functions silc_client_send_private_message_key to send
          the Private Message Key payload and silc_client_private_message_key
          to handle incoming Private Message Key payload.

        * Added Cipher field to the Private Message Key payload to set
          the cipher to be used.  If ignored, the default cipher defined
          in the SILC protocol (aes-256-cbc) is used.

Tue Feb 27 13:30:52 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Removed lib/silcclient/ops.h file.

          Redefined parts of the SILC Client Library API. Created new
          file silcapi.h that deprecates the ops.h file and defines the
          published Client Library API.  Defined also private message key
          API and channel private key API into the file.

          This is the file that the application must include from the
          SILC Client Library.  Other files need not be included by
          the application anymore.

        * Added new key_agreement client operation callback and also
          defined the Key Agreement library API for the application.

Tue Feb 27 11:28:31 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added new packet type: SILC_PACKET_KEY_AGREEMENT.  This packet
          is used by clients to request key negotiation  between another
          client in the SILC network.  If the negotiation is started it
          is performed using the SKE protocol.  The result of the
          negotiation, the secret key material, can be used for example
          as private message key.

          Implemented the Key Agreement payload into the files
          lib/silccore/silauth.[ch].

Mon Feb 26 12:13:58 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Redefined ciphers for the SILC protocol.  Added some new ciphers
          and defined the key lengths for the algorithms.  Changed the
          code accordingly.  The default key length is now 256 bits.

        * Fixed SKE key distribution function silc_ske_process_key_material
          when the key length is more than 128 bits.  The default key
          length in SILC is now 256 bits.

        * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
          to indicate unsupported algorithm.

        * Renamed rijndael.c to aes.c and all functions as well.

        * Fixed a long standing channel key setting bug in client library.
          Weird that it has never surfaced before.

        * Fixed bug in channel deletion.  If the entire channel is removed
          then it must also delete the references of the channel entry
          from the client's channel list as the client's channel entry and
          the channel's client entry share same memory.

Sun Feb 25 20:47:29 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Implemented CONNECT and SHUTDOWN commands in the client.

        * Implemented CLOSE command to the client.

        * Added the function silc_idlist_find_server_by_name into the
          files silcd/idlist.[ch].

          Added the function silc_idlist_find_server_by_conn into the
          files silcd/idlist.[ch].

Sat Feb 24 23:45:49 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * DIE command was renamed to SHUTDOWN.  Updated the both code
          and protocol specs.

        * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
          SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.

        * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
          side.

        * Added function silc_server_create_connection function to create
          connection to remote router.  My server implementation actually
          does not allow router to connect to normal server (it expects
          that normal server always initiates the connection to the router)
          so the CONNECT command is only good for connecting to another
          router.

Sat Feb 24 16:03:45 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
          or some other client was kicked from the channel.

          Implemented the handling of the notify type to both client
          and server.

          Implemented silc_server_send_notify_kicked to send the KICKED
          notify.  It is used to send it to the server's primary router.

        * Implemented the KICK command into server and client.

        * Added `query' argument to the silc_idlist_get_client function
          to indicate whether to query the client from server or not if
          it was not found.

        * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
          to indicate that the client is not channel founder.

        * Updated TODO.

Sat Feb 24 00:00:55 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Removed the rng context from SilcPacketContext structure and
          changed that the packet routine uses the Global RNG API.

Fri Feb 23 11:22:57 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added support for quit message that client can "leave" on the
          channel when it quits the SILC.  It is ditributed inside the
          SILC_NOTIFY_TYPE_SIGNOFF notify type.

          Added silc_server_free_client_data that will take the
          signoff message as argument.

        * Changed SKE routines to use the silc_pkcs_sign/verify routines.

Thu Feb 22 23:05:36 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Updated parts of the protocol specification to keep it up
          to date.

Thu Feb 22 15:08:20 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
          payloads in one packet.

        * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
          NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST.  List packets
          use now the new List flag.

        * Also deprecated the following packet types: REPLACE_ID,
          NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.

        * Added list support for Notify packet in server.

        * Added silc_server_send_notify_channel_change to send the
          CHANNEL_CHANGE notify type to replace channel ID's.  Deprecates
          the silc_server_send_replace_id.

        * Added silc_server_send_notify_nick_change to send the
          NICK_CHANGE notify type.  Deprecates the function
          silc_server_send_replace_id.

        * Added silc_server_send_notify_join to send the JOIN notify type.
          Deprecates the function silc_server_send_new_channel_user.

        * Added silc_server_send_notify_leave to send LEAVE notify type.
          Deprecates the function silc_server_send_remove_channel_user.

        * Added silc_server_send_notify_cmode and
          silc_server_send_notify_cumode to send CMODE and CUMODE notify
          types.  Deprecates the silc_server_send_set_mode function.

        * Added SERVER_SIGNOFF notify type to indicate that server has
          quit.  This means that all clients on the channel from that
          server will drop.  This can be also used when netsplit happens.

          Deprecated REMOVE_ID packet type since it is not needed anymore
          even from server.

          Added silc_server_send_notify_server_signoff to send the
          SERVER_SIGNOFF notify type.  Deprecates the function
          silc_server_send_remove_id.

          Added also silc_server_send_notify_signoff to send the
          SIGNOFF notify type.

        * Employed the PKCS #1. It is the mandatory way to do RSA in the
          SILC protocol from this day on.  Changed the protocol
          specification as well.

        * Added silc_server_send_notify_topic_set to send TOPIC_SET
          notify type.  It is used between routers to notify about
          topic changes on a channel.

        * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
          ID data.

        * Partly updated the protocol specification to comply with the
          changes now made.  It is still though a bit outdated.

        * The JOIN notify type now takes one extra argument <Channel ID>.
          The packet used to be destined to the channel but now the
          JOIN type may be sent as list thus it is impossible to
          destine it to any specific channel.  By adding this argument
          it is again possible.

Wed Feb 21 22:39:30 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added CREDITS file.  The CHANGES and CREDITS file will appear
          in the distribution as well.

Wed Feb 21 14:17:04 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
          types in the server's silcd/packet_receive.c.

        * Implemented CMODE and CUMODE to work in router environment.

        * Fixed minor encoding and decoding buglet from the
          lib/silccore/silcmode.c.

        * Fixed buffer overflow from lib/silcclient/command.c in USERS
          command parsing.

Wed Feb 21 12:44:00 EET 2001  Mika Boström <bostik@lut.fi>

        * Changed all SilcConfigServer* and silc_config_server* to
          SilcServerConfig* and silc_server_config*, respectively.
          Patch by Bostik.

Wed Feb 21 00:10:00 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Associated the ID (client or server ID) to the Authentication
          Payload to avoid any possibility of forging.  Updated the
          protocol specification and the code accordingly.

Tue Feb 20 14:14:14 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * The RSA key length is now save to the RsaKey context in the
          key generation process in lib/silccrypt/rsa.c.  The key length
          is now used to figure out the maximum size of the block allowed
          to be encrypted/signed.

        * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch].  It
          is equivalent to the silc_mp_mp2bin but does not allocate any
          memory.

        * Changed silc_mp_mp2bin API to take length argument.  If it is
          non-zero then the buffer is allocated that large.  If zero, then
          the size is approximated using silc_mp_sizeinbase, which however
          is not relieable.

        * Created Global RNG API which is global RNG that application can
          initialize.  After initializing, any routine anywhere in the
          code (including library) can use RNG without allocating a new
          RNG object.  This was done to allow this sort of use of the
          RNG in code that has no chance to allocate RNG object.  All
          applications currently allocate this and many routines in the
          library use this.  Affected file lib/silccrypt/silcrng.[ch].

        * Removed the RNG kludge from lib/silcmath/primegen.c and changed
          it to use the Global RNG API.

        * Defined Authentication Payload into protocol specification that
          is used during SILC session to authenticate entities.  It is
          used for example by client to authenticate itself to the server
          to obtain server operator privileges.

          Implemented this payload into the lib/silccore/silcauth.[ch].
          Implemented also routines for public key based authentication
          as the new protocol specification dictates.

          Moved definitions of different authentication methods from
          lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.

        * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
          silc_pkcs_verify and silc_pkcs_sign_with_hash and
          silc_pkcs_verify_with_hash functions into the file
          lib/silccrypt/silcpkcs.[ch].

Mon Feb 19 19:59:28 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * The client entry's userinfo pointer must be always valid.
          Otherwise the [<unknown>] bug will surface beacuse the WHOIS
          will fail since it requires the userinfo.  Now, the userinfo
          is allocated as "" if actual userinfo does not exist.  Actually,
          it must exist and it is totally Ok to drop client connections
          that does not announce the userinfo.  However, we will make
          this workaround for now.

        * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
          to return the remote port by socket.

Mon Feb 19 14:26:49 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
          SILC_SERVER_PENDING_EXEC and added an new macro
          SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
          data or when error occurs while processing the pending command.

          Added new argument `destructor' into silc_server_command_pending
          and to the SilcServerCommandPending object.  This destructor is
          now called after calling the pending callback or if error occurs
          immediately.  If error occurs the actual pending callback won't
          be called at all - only the destructor.  The destructor may be
          NULL if destructor is not needed.

          All this applies for client library code as well.  Similar
          changes were made there as well for the pending commands.

          In the client, the application must now allocate the
          SilcClientCommandContext with the silc_client_command_alloc
          function.

        * Added reference counter to the SilcServerCommandContext.  Added
          function silc_server_command_alloc and silc_server_command_dup
          functions.

          Same type of functions added to the client library for the same
          purpose as well.

        * Removed the cmd_ident from IDListData away since it is now
          global for all connections.  It is the command identifier used
          in command sending and with pending commands.  The affected file
          is silcd/idlist.h.

        * Added reference counter to the SilcSocketConnection objecet to
          indicate the usage count of the object.  The object won't be
          freed untill the reference counter hits zero.  Currently only
          server uses this, and client ignores it.  The client must be
          set to use this too later.  The affected files are
          lib/silccore/silcsockconn.[ch].  Added also the function
          silc_socket_dup to increase the reference counter.

          This was mainly added because it is possible that the socket
          is removed underneath of pending command or other async
          operation.  Now it won't be free'd and proper DISCONNECTING
          flags, etc. can be set to avoid sending data to connection that
          is not valid anymore.

        * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
          the connection.  After that it sets SILC_SET_DISCONNECTED.
          It is, however, possible that the socket data is not still freed.
          The silc_server_packet_process now checks that data is not
          read or written to connection that is DISCONNECTED.  The socket
          get's freed when the reference counter hits zero.

Mon Feb 19 00:50:57 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Changed the client operation API: channel_message operation's
          `sender' is now the client entry of the sender, not the nickname
          and the `channel' is the channel entry, not the channel name.

          In the private_message operation the `sender' is now also the
          client entry of the sender not the nickname.

          Affected file is lib/silcclient/ops.h and all applications
          using the client operations.

Sat Feb 17 22:11:50 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Moved the calling of ops->connect() from connect_to_server_final
          into receive_new_id functin since that is the point when the
          client is actually allowed to send traffic to network.  The
          affected file is lib/silcclient/client.c.

Sat Feb 17 13:15:35 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
          NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
          (if needs broadcasting) instead of broadcasting the packets one
          by one which would make a burst in the network traffic.

        * Added `broadcast' argument to the functions in silcd/server.[ch]
          silc_server_create_new_channel[_with_id] to indicate whether
          to send New Channel packet to primary router.

Sat Feb 17 01:06:44 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added new function into the silcd/server.[ch] files:
          silc_server_create_new_channel_with_id to create new channel with
          already existing Channel ID.

        * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
          lib/silccore/silcpacket.h.  This packet is used t send list of
          Set Mode payloads inside one packet.  Server uses this to set
          the modes for the channels and clients on those channels, that it
          announced to the router when it connected to it.  The protocol
          specification has been updated accordingly.

        * The silc_server_new_channel did not handle the packet coming
          from normal server as it normally does not send that.  However,
          when it announces its channels it does send it.  Implemented
          the support for that.

        * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
          into the file lib/silccore/id.h.

Fri Feb 16 23:57:29 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed memory leaks in the functions silc_idlist_del_client,
          silc_idlist_del_channel and silc_idlist_del_server in the file
          silcd/idlist.c.  All of those leaked like a sieve.

        * Fixed some small memory leaks in the client's function
          silc_client_notify_by_server.

        * Added functions into silcd/server.c: silc_server_announce_clients,
          silc_server_announce_channels and silc_server_announce_server.
          These functions are used by normal and router server to announce
          to its primary router about clients, channels and servers (when
          router) that we own.  This is done after we've connected to the
          router.

          These functions effectively implements the following packet types:
          SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
          and SILC_PACKET_NEW_ID_LIST.

        * Added new functions into the silcd/packet_receive.[ch]:
          silc_server_new_id_list, silc_server_new_channel_list and
          silc_server_new_channel_user_list to handle the incoming
          NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.

        * Added support of changing Channel ID in the function
          silc_server_replace_id.  If the server that announces a channel
          to the router already exists in the router (with same name but
          with different Channel ID), router is responsible to send
          Replace ID packet to the server and force the server to change
          the Channel ID to the one router has.

        * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
          client that the Channel ID has been changed by the router.  The
          normal server sends this to the client.  Client must start using
          the new Channel ID as the channel's ID.

          Implemented handling of this new type into lib/silcclient/client.c
          into the function silc_client_notify_by_server.

        * Added new function silc_idlist_replace_channel_id into the files
          silcd/idlist.[ch] to replace the Channel ID.

Fri Feb 16 14:14:00 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Call silc_server_command_identify_check always when processing
          the IDENTIFY command in silcd/command.c

Thu Feb 15 20:07:37 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added new packet type SILC_PACKET_HEARTBEAT that is used to
          send keepalive packets.  The packet can be sent by clients,
          servers and routers.

          Added function silc_socket_set_heartbeat into the file
          lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
          If not set, the heartbeat is not performed.  The actual
          heartbeat is implemented in the low level socket connection
          library.  However, application is responsible of actually
          sending the packet.

          Added silc_server_send_heartbeat to send the actual heartbeat
          packet into silcd/packet_send.[ch].  Server now performs
          keepalive with all connections.

        * Added silc_task_get_first function into lib/silcutil/silctask.c
          to return the timeout task with shortest timeout.  There was a bug
          in task unregistration that caused problems.  TODO has been
          updated to include that task system must be rewritten.

        * The client library will now resolve the client information when
          receiving JOIN notify from server for client that we know but
          have incomplete information.

        * Rewrote parts of silc_server_remove_from_channels and
          silc_server_remove_from_one_channel as they did not remove the
          channel in some circumstances even though they should've.

        * Encryption problem encountered in server:

          The LEAVE command used to send the Channel Key packet to the
          router immediately after generating it.  However, the code
          had earlier sent Remove Channel user packet but not immediately,
          ie. it was put to queue.  The order of packets in the router
          was that Channel Key packet was first and Remove Channel User
          packet was second, even though they were encrypted in the
          reverse order.  For this reason, MAC check failed.  Now, this
          is fixed by not sending the Channel Key packet immediately but
          putting it to queue.  However, this is more fundamental problem:
          packets that are in queue should actually not be encrypted
          because packets that are sent immediately gets encrypted
          actually with wrong IV (and thus MAC check fails).  So, packets
          that are in queue should be encrypted when they are sent to
          the wire and not when they put to the queue.

          However, the problem is that the current system has not been
          designed to work that way.  Instead, the packet is encrypted
          as soon as possible and left to the queue.  The queue is then
          just purged into wire.  There won't be any fixes for this
          any time soon.  So, the current semantic for packet sending
          is as follows:

          o If you send packet to remote host and do not force the send
          (the packet will be in queue) then all subsequent packets to the
          same remote host must also be put to the queue.  Only after the
          queue has been purged is it safe again to force the packet
          send immediately.

          o If you send all packets immediately then it safe to send
          any of subsequent packets through the queue, however, after
          the first packet is put to queue then any subsequent packets
          must also be put to the queue.

          Follow these rules and everything works fine.

Thu Feb 15 14:24:32 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added new function silc_server_remove_clients_by_server to
          remove all client entries from ID list when the server connection
          is lost.  In this case it is also important to invalidate all
          client entires as they hold the invalid server entry.  This
          fixes fatal bug when server has lost connection and will reconnect
          again.

Wed Feb 14 16:03:25 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Made some sanity checks to silc_server_daemonise like to check
          whether the requested user and group actually exists.

        * Added sanity check to SKE's silc_ske_responder_finish to check
          that the public and private key actually is valid.

        * Invalidate the client's nickname when receiving Replace ID
          packet and the Client ID is being replaced.  This means that the
          server will query the nickname if someone needs it (client)
          a bit later.

        * Sort the ID Cache in client library when the ID Cache data
          has changed (needs sorting).

        * Do not allow for SILC client to create several connections to
          several servers.  The client does not support windows right now
          and generating multiple connections causes weird behaviour.

          Irssi-silc client does support windows and can handle several
          connections without problems, see: www.irssi.org and SILC plugin.

        * Fixed some places where client was added to the IDList.  The
          rule of thumb is following (in order to get everything right):
          If the client is directly connected local client then the
          `connection' argument must be set and `router' argument must be
          NULL to silc_idlist_add_client function.  If the client is not
          directly connected client then the `router' argument must
          bet set and the `connection' argument must be NULL to the
          silc_idlist_add_client function.

        * The funtion silc_server_packet_send_local_channel actually did
          not check whether the client was locally connected or not.  It
          does that now.  Fixed a bug related to LEAVE command.

        * Fixed Remove Channel User payload parsing bug in server's
          silcd/packet_receive.c.  Fixed a bug related to LEAVE command.

        * The server's silc_server_save_channel_key now checks also the
          global ID list for the channel as it might not be in the local
          list.  Fixed a bug related to LEAVE command.

        * Is this the end of the [<unknown>] buglet that has been lurking
          around for a long time?  A little for loop fix in server's
          silc_server_command_whois_parse that is used by both IDENTIFY
          and WHOIS command.  At least, this was a clear bug and a cause
          of one type of [<unknown>] buglet.

        * WHOIS and IDENTIFY commands call the function
          silc_server_command_[whois/identify]_check function even if
          we are not router server.

Tue Feb 13 19:55:59 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added --with-gmp configuration option.  If set the GMP
          is always compiled in the SILC source tree.  If not set then
          it is checked whether the system has the GMP3 installed.  If
          it has then the GMP won't be compiled (the system's headers
          and library is used), if it doesn't have it then the GMP is
          compiled in the SILC source tree.

Mon Feb 12 11:20:32 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Changed RSA private exponent generation to what PKCS #1
          suggests.  We try to find the smallest possible d by doing
          modinv(e, lcm(phi)) instead of modinv(e, phi).  Note: this is
          not security fix but optimization.

Sun Feb 11 18:19:51 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added new config entry [Identity] to fork the server and run
          it as specific user and group.  A patch from Bostik.

        * Imported Dotconf configuration library into lib/dotconf.
          This will be used to create the SILC configuration files later.
          It will appear in the distsribution after this commit.

Sat Feb 10 21:13:45 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * A big code auditing weekend happening.  Auditing code for
          obvious mistakes, bugs and errors.  Also, removing any code
          that is obsolete.

          Removed files for being obsolete:

          o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
          inline in the file lib/silcutil/silcbuffer.h)

          o lib/silcutil/silcbufutil.c (the header has inline versions)

          Changed code to fix possible error conditions:

          o The buffer formatting routines now check that the destination
          buffer really has enough space to add the data.  This applies for
          both buffer formatting and unformatting
          (lib/silcutil/silcbuffmt.[ch]).  Also, the entire buffer
          unformatting was changed to accomodate following rules:
          XXX_*STRING_ALLOC will allocate space for the data into the pointer
          sent to the function while XXX_*STRING will not allocate or copy
          the data into the buffer.  Instead it sets the pointer from the
          buffer into the pointer sent as argument (XXX_*STRING used to
          require that the pointer must be allocated already).  This change
          makes this whole thing a bit more consistent and more optimized
          (note that the data returned in the unformatting with XXX_*STRING
          must not be freed now).  The routines return now -1 on error.

          o Tried to find all code that use buffer_format and buffer_unformat
          and added return value checking to prevent formatting and
          especially unformatting errors and possible subsequent fatal
          errors.

          o Changed ske->x and ske->KEY to mallocated pointers in
          lib/silcske/silcske.h.  Fixed possible data and memory leak.

          o Added return value checking to all *_parse* functions.  Fixed
          many memory leaks as well.

          o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
          so that buffer overflows would not happen.  All code now also
          checks the return value as it can fail.

Mon Feb  5 20:08:30 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added reconnection support to server if the normal server looses
          its connection to the router (for example if router is rebooted).
          The server performs normal reconnection strategy implemented
          to the server.  Affected file silcd/server.c.

Sun Feb  4 13:18:32 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added new packet type SILC_PACKET_SET_MODE that is used to
          distribute the information about changed modes (for clients,
          channels and clients channel modes) to all routers in the
          network.  Updated the protocol specification accordingly.

          Added functions into silcd/packet_send.c and
          silcd/packet_receive.c: silc_server_send_set_mode,
          silc_server_set_mode.

          Added new files silcmode.[ch] into lib/silccore that implements
          the encoding and decoding of Set Mode Payload.  Added new type
          SilcSetModePayload.  Moved the definitions of different modes
          from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.

Sat Feb  3 15:44:54 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Oops, a little mistake in server's connection authentication
          protocol.  The protocol is not ended with FAILURE but with
          SUCCESS if the authentication is Ok. :)  Affected file is
          silcd/protocol.c.

        * Implemented NICK_CHANGE notify handling in server in the file
          silcd/packet_receive.c  The NICK_CHANGE notify is distributed to
          the local clients on the channel.  After the changing nickname
          in router environment snhould work and the [<unknown>] nickname
          should appear no more.

          The silc_server_replace_id function that receives the Replace ID
          payload now sends the NICK_CHANGE notify type also in the file
          silcd/packet_receive.c

        * Changed WHOIS and IDENTIFY command to support the maximum amount
          of arguments defined in protocol specs (3328 arguments).  This
          fixed a bug that caused problems when there were more than three
          users on a channel.

Fri Feb  2 11:42:56 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added extra parameter, command identifier, to the
          silc_client_send_command so that explicit command identifier
          can be defined.

          Changed that ID list routines uses specific command identifier
          when sending WHOIS/IDENTIFY requests to the server so that they
          can be identified when the reply comes back.

          Affected files lib/silcclient/command.[ch],
          lib/silcclient/client.c and lib/silcclient/idlist.[ch].

        * Added `sender' argument to silc_server_packet_send_to_channel
          to indicaet the sender who originally sent the packet to us
          that we are now re-sending.  Ignored if NULL.  Affected file
          silcd/packet_send.[ch].

        * Added some server statistics support in silcd/server_internal.h
          SilcServerStatistics structure and around the server code.  Also
          send some nice statistics information when client is connecting
          to the client.

Thu Feb  1 23:31:21 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed channel ID decoding in server's JOIN command reply in
          silcd/command_reply.c

        * Fixed braodcasting of replace ID payload to not to send it if
          we are standalone server in silcd/packet_receive.c.

        * Fixed all channel message sending routines to not to send
          packets to clients that has router set, since they are routed
          separately in the same function earlier.  Affects file
          silcd/packet_send.c and all channel packet sending functions.

        * In USERS reply, res_argv[i] are not allocated, the table
          is allocated.  Thus changed that free the table, not its
          internals.

        * In server's whois_check and identify_check if the client is
          locally connected do not send any WHOIS commands - they are not
          needed.

Thu Feb  1 21:32:27 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed some minor bugs in client when sending WHOIS command.  The
          arguments was in wrong order.

        * Removed statis function add_to_channel from server in
          silcd/command.c that was previously used with the joining but
          is obsolete now.

        * Tested USERS command in router environment successfully with two
          routers, two servers and two clients.

Thu Feb  1 00:54:26 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Reorganized the USERS command and command reply in client library
          in lib/silcclient/command.c and lib/silcclient/command_reply.c.
          When the command is given by user we register a pending command
          callback that will reprocess the command after the reply has been
          received from the server.  When reprocessing the packet we then
          display the information.  Thus, the USERS information is displayed
          now in the command callback instead of in the command reply
          callback.  The processing of the command is same as previously
          when server has sent the command reply in the JOINing process.

        * Added to USERS command in silcd/command_reply.c to join the client,
          we didn't use to know about, to the channel after we've created
          a client entry for it.  Also, for clienet we did know already still
          check whether it is on the channel or not and add it if not.

        * Removed silc_server_command_join_notify as the function and its
          use was obsolete.

Tue Jan 30 22:39:15 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Changed the client's pending command handling to the same as the
          server's pending command handling.  It is also now possible to
          execute command reply functions from other command reply
          function as the function callbacks for commands and command
          replies are one and same.  The pending commands are not static
          list anymore, it is mallocated SilcDList in lib/silcclient/client.h
          in client connection context.  Thus, pending commands are server
          connection specific as it is convenient.

          Changed the function silc_client_command_pending and
          silc_client_command_pending_del and added new function
          silc_client_command_pending_check.  Removed the
          SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
          macros.

        * Added cmd_ident, current command identifier, to the client
          connection context in lib/silcclient/client.h to keep track on
          command identifiers used in command sending.  Client's command reply
          function handling now supports the mandatory command identifiers.

        * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
          funtions in client to fully support pending command callbacks.

        * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
          as one of the arguments to the application in the command reply
          client operation.

        * NOTE: The FORWARDED flag is depracated.  It used to be depracated
          before first releasing SILC but came back.  Now it is removed again
          and should come back nomore.  The FORWARDED flag was used only
          by the JOINing procedure by forwarding the command packet to router.
          Now, the JOINing procedure has been changed to more generic (due
          to various router environment issues) and FORWARDED is not needed
          anymore for anything.  The protocol specification is yet to be
          updated.

          Now, removed silc_server_packet_forward from server and the flag
          SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.

Tue Jan 30 00:05:05 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Renamed NAMES command to USERS command.  The NAMES was named that
          due to historical reasons.  Now it is renamed.  Also, rewrote
          parts of the USERS command.  The nickname list is not sent anymore
          by the server.  Only Client ID and mode lists are sent in the USERS
          command.  Changed this also to the protocol specification.

          The client now resolves the names and stuff after it receives
          the USERS list from the server when joining to the channel.

        * WHOIS and IDENTIFY commands has been changed to support multiple
          Client ID's per command.  One can now search for multiple users
          in the network by sending only one WHOIS or IDENTIFY command.
          Changed the code and the protocol specifications.

        * Removed silc_server_command_identify_parse and changed that IDENTIFY
          uses silc_server_command_whois_parse to parse the request. */

        * If normal server, do not parse the WHOIS and IDENTIFY requests
          before sending it to the router.  Saves some time.

Sun Jan 28 16:19:49 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed JOIN command on client library.  Wrong number of arguments
          used to crash the client.

        * Added silc_server_channel_has_global function to check whether
          channel has global users or not.

        * Added silc_server_channel_has_local function to check whether channel
          has locally connected clients on the channel.

        * The silc_server_remove_from_one_channel now checks whether the
          channel has global users or not after given client was removed from
          the channel.  It also checks whether the channel has local clients
          on the channel anymore.  If it does not have then the channel entry
          is removed as it is not needed anymore.

        * The silc_server_notify now checks on JOIN notify whether the joining
          client is one of locally connected or global.  If it is global then
          the channel has now global users on the channel and that is marked
          to the channel entry.  Also, it now saves the global client to
          global list who is joining and JOINs it to the channel.  This is
          for normal server, that is.

          Changed silc_server_send_notify_on_channel,
          silc_server_packet_relay_to_channel and
          silc_server_packet_send_to_channel check if we are normal server
          and client has router set (ie. global client) do not send the
          message to that client, as it is already routed to our router.

        * Implemented LEAVE notify type handling in silc_server_notify
          function.

        * Tested LEAVE command in router environment successfully.  Tested
          with two routers, two servers and two clients.

        * Updated TODO.

        * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.

        * Implemented SIGNOFF notify type handling in silc_server_notify
          function.

        * silc_server_remove_id now removes the client entry from all channels
          it has joined and thusly sends SIGNOFF notify type.

        * Rewrote the NAMES list generation in server by removing two excess
          loops.  The lists are created now inside one loop.

Sat Jan 27 22:34:56 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * silc_server_remove_channel_user checks now also global list
          for channel and client.

        * silc_server_new_channel_user checks now both local and global
          list for channel and client.  Fixed a bug in client id decoding.
          Used to decode wrong buffer.

        * silc_server_channel_message checks now both local and global
          list for channel entry.

        * Tested channel joining (hence JOIN) in router environment
          successfully.  Tested with two routers, two servers and two
          clients.

        * Tested channel message sending in router environment successfully.

Thu Jan 11 03:22:57 EET 2001  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added silc_server_save_channel_key into server.[ch] to save the
          received channel key in Channel Key payload processing. It is
          also used in JOIN command reply handling.

          Equivalent function silc_client_save_channel_key added into
          client.[ch] into client library.

        * Changed JOIN command reply to send information whether the channel
          was created or not (is existing already) and the channel key
          payload.  Changed protocol specs accordingly.

        * Fixed bugs in WHOIS and IDENTIFY command reply sending when
          the request was sent by ID and not by nickname.  Crashed on
          NULL dereference.

Sat Dec 23 21:55:07 EET 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed a bug in Client library.  IDENTIFY and WHOIS reply functions
          now correctly save the received data.

        * silc_server_free_sock_user_data now notifies routers in the
          network about entities leaving the network.

          At the same time implemented functions silc_server_remove_id
          and silc_server_send_remove_id to receive and send REMOVE_ID
          packets.  The packet is used to notify routers in the network
          about leaving entities.  The ID removed will become invalid in
          the network.

        * Added function silc_idlist_del_server into server. Removes and
          free's server entry from ID list.

        * silc_server_private_message function now checks, if we are router,
          that the destination ID really is valid ID, naturally.

        * In router when NEW_ID packet is received (for new client) the
          hash of the Client ID is saved in the ID Cache but the
          client->nickname is set to NULL, instead of putting the hash
          to it as well.

          IDENTIFY command now also checks that client->nickname must be
          valid. If it is not if will request the data from the server who
          owns the client.  Added new function
          silc_server_command_identify_check.

        * Added silc_command_set_command into lib/silccore/silcommand.[ch]
          to set the command to already allocated Command Payload.

        * Tested private message sending in router environment with two
          routers, two servers and two clients.  Fixed minor bugs and now
          it works fine.

        * Fixed segfault from client's NAMES command. Used to crash if
          not on any channel.

        * Forwarded packets must not be routed even if it is not destined
          to the receiver.  Changed server code comply with this.

Sun Dec 17 14:40:08 EET 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added `require_reverse_mapping' boolean value to ServerParams
          structure. If TRUE (not default) the server will require that
          the connecting host has fully qualified domain name.

          If the reverse mapping is not required and hostname could not be
          found the IP address is used as hostname.

Sat Dec 16 17:39:54 EET 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Implemented version string checking to both client and server.
          The check is incomplete currently due to the abnormal version
          strings used in development version of SILC.

        * Changed all command functions in server to use the new
          CHECK_ARGS macro.

Fri Dec 15 15:55:12 EET 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Changed char *data to unsigned char *data in ID Cache system to
          support binary data as ID Cache data. Changed code to support
          binary data in lib/silccore/idcache.c.

        * Renamed silc_server_packet_relay_command_reply to
          silc_server_command_reply as it is normal packet receiving
          function. Rewrote the function to accept command replys for
          servers and not only for clients.

        * Mark remote router always as registered server if we are connecting
          to it.  Otherwise, commands sent by the router to us are ignored.

        * All ID List find routines now returns the ID Cache Entry pointer
          as well if requested.

        * WHOIS command works now in router environment, tested with two
          routers, two servers and two clients.

        * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
          in router environment (as it is almost equivalent to WHOIS) but
          hasn't been tested thoroughly.  Added new functions:

          silc_server_command_identify_parse
          silc_server_command_identify_send_reply
          silc_server_command_identify_from_client
          silc_server_command_identify_from_server

        * Disabled route cache adding because adding two different ID's with
          same IP replaces the old cache entry thus giving wrong route.
          The entry->router->connection is always the fastest route anyway
          so route cache may not be needed.  Of course, new routes maybe
          established after receiving the ID when the entry->router->connection
          might not be anymore the most optimal.

Thu Dec 14 15:55:35 EET 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Add route cache for received ID for fast routing.

        * Added silc_server_packet_route to route received packet on router
          that is not destined to us.

        * Renamed silc_server_get_route to silc_server_route_get.

        * Added id_string and id_string_len fields into SilcServer to
          include encoded ServerID for fast comparing without excess
          encoding of the ID's.

        * Cleaned up WHOIS command on server side. Added following static
          functions:

          silc_server_command_whois_parse
          silc_server_command_whois_check
          silc_server_command_whois_send_reply
          silc_server_command_whois_from_client
          silc_server_command_whois_from_server

        * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
          arguments in command replies. All command functions should be
          updated to use this macro.

Sun Dec 10 23:52:00 EET 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Minor typo fixes on command reply handling on server.

Tue Nov 28 11:05:39 EET 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added silc_server_command_add_to_channel internal routine to add
          the client to the channel after router has created the channel and
          sent command reply to the server.

        * Added generic silc_server_send_command to send any command from
          server.

        * Use static buffer with ID rendering instead of duplicating data.

Mon Nov 27 21:39:40 EET 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed a channel user mode bug when joining to a channel server gave
          everybody channel founder rights, oops.

        * We mark ourselves as the router of the incoming server connection
          if we are router ourselves.  This way we can check in some packet
          sending functions whether it is locally connected server.  For
          incoming router connections we put NULL.

        * For router sending packets locally means now always sending the
          packet cell wide; to local clients and local servers.  For normal
          server sending packet locally means sending it to only local
          clients.

        * Fixed the JOIN command to really work in router environment.  If the
          channel is created it is always created by the router.  Router is
          also responsible of making the initial joining to the channel,
          sending JOIN notify to the sending server and distributing
          NEW_CHANNEL and NEW_CHANNEL_USER packets.  Hence, if the channel
          does not exist server doesn't do anything else but forward the
          command to the router which performs everything.

        * Added silc_server_send_channel_key function to send the Channel Key
          payload.

        * Added silc_server_create_channel_key to create new channel key.  The
          channel key is now re-generated everytime someone joins or leaves
          a channel, as protocol dictates.  Note: channel->key_len is the
          key length in bits.

Wed Nov 22 22:14:19 EET 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Splitted server.[ch] finally.  Created now packet_send.[ch] and
          packet_receive.[ch] to separate packet sending and receiving
          routines.  The server.[ch] now includes everything else including
          actual packet processing (writing and reading data) and other
          server issues.

          Renamed silc_server_private_message_send_internal to
          silc_server_send_private_message.  The routine is still though
          used only to relay private messages as server does not send
          private messages itself.

          Renamed silc_server_new_channel to silc_server_create_new_channel
          and added new function sicl_server_new_channel that handles the
          incoming New Channel packet.  Added also new sending function
          silc_server_send_new_channel to send New Channel Payload.

        * Added new function silc_server_notify to process incoming notify
          packet to the server/router. Server may then relay the notify
          to clients if needed.

        * Added new function silc_server_new_channel_user to process incoming
          New Channel User packet.  Router will redistribute the packet and
          send JOIN notify to its local clients and locally connected servers
          if needed.  Normal server will send JOIN notify to its local client
          on same channel when received this packet.  Added also corresponding
          sending function silc_server_send_new_channel_user to sent the
          payload.

        * Added boolean route argument to send_notif_to_channel and
          packet_send_to_channel functions to attempt to route the packet
          if it is TRUE and send only locally if it is FALSE.

Tue Nov 21 19:49:31 EET 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * silc_server_replace_id now broadcasts the received replace ID
          packet if it is not broadcast packet already. The router must
          broadcast to inform other routers about changed ID.

        * Added backpointer to server's router into SilcServer context in
          silcd/server_internal.h.

        * Fixed silc_server_packet_broadcast to send correct broadcast
          packets.

        * The channel key is now distributed to the local client as soon
          as it is received from the router (in router environment) so that
          no other packet may be sent for the channel until client has
          received the key.

        * silc_server_remove_channel_user now broadcasts the received
          Remove Channel User packet if it is not broadcast packet already.
          The router must broadcast to inform other routers about removed
          channel user.

        * Added users field into SilcPacketContext that is a reference count
          of the context.  One can increase the reference count by calling
          silc_packet_context_dup which is now changed to just increase the
          reference count instead of duplicating the data.  The reference
          count is decresed by calling silc_packet_context_free that will
          free the data after the reference count hits zero.

          For now on the packet context and everything allocated into it
          (including the raw packet from network) must be freed by calling
          the new silc_packet_context_free function.  Added also new function
          silc_packet_context_alloc that must be used now to allocate the
          context.  This also means that if a routine is asynchronous from
          silc_[client/server]_packet_parse_type the packet context must
          be duplicated by calling silc_packet_context_dup.  Otherwise it
          gets free'd after silc_[client/server]_packet_parse_type returns.
          Also, one must remember that if packet is duplicated then its
          reference count must be decresed by calling the free function as
          many times as it was duplicated.

        * Changed SilcBuffer field from protocol contexts to SilcPacketContext
          from both client and server.

Mon Nov 20 23:47:03 EET 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Made joining to a channel working in router environment.

        * Cleaned up JOIN command on server side and create function
          silc_server_command_join_channel internal routine to make the
          joining happen.

Thu Nov  9 21:12:39 EET 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Changed silc_command_pending list to SilcDList.  Also, added
          `ident' field to SilcServerCommandPending structure to identify
          the reply and to call correct callback.

          Added silc_server_command_pending_check function to replace the
          corresnponding macro.  The silc_command_pending list is not
          extern anymore.

        * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
          to set identifier to previously allocated Command Payload.  It
          is used to set identifier for command when resending Command
          Payload.

        * Added silc_command_payload_encode_payload to encode Command
          Payload buffer from SilcCommandPayload structure.

        * Added silc_argument_payload_encode_payload to encode Argument
          payload buffer from SilcArgumentPayload structure.

Wed Nov  8 21:03:28 EET 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Changed WHOIS command to support router connection on server side.
          The whois request is always sent to router unless the server is
          standalone server.  After server has received the reply from the
          router will it send the reply to the client.

        * Added silc_server_packet_broadcast into silcd/server.[ch] to
          broadcast received broadcast packet.  The function is used only
          by router.  The broadcast packet is always sent to the router's
          primary route.

        * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
          render given ID to printable string, for log files for example.

Tue Nov  7 22:14:19 EET 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Made basic router to router connections working.  At least they
          can now connect to each other but nothing really works the way
          they are supposed - yet.

        * Added new initiator token to RouterConnection configuration
          file in silcd/serverconfig.[ch].  It is used to tell whether we
          are the initiator to the remote router or whether we'll expect
          the other end to connect.

        * Moved registering of listener task to silc_server_init, hence
          the server starts listenning as soon as it is run, even if it
          does not have connections to other routers.  Let's see how well
          this will work.

        * Changed default connection retry timeouts for more suitable in
          silcd/server.h.

        * Removed cipher and such arguments from silc_idlist_add_client
          and silc_idlist_add_server prototypes from silcd/idlist.[ch].
          Added new function silc_idlist_add_data to add the keys and stuff
          to any ID entry.

        * Added SilcIDListData structure and added it to SilcClientEntry
          and SilcServerEntry as their first field in the structure.  This
          way we can explicitly cast the ID entries to the SilcIDListData
          structure and get common data for the entries.  In past, we had
          to first check what type of connection it is and then cast it to
          correct ID entry type.  Now, we can directly cast the opaque
          pointer to the SilcIDListData (no matter what ID entry it actually
          is) and get the data needed.

Mon Nov  6 21:56:12 EET 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Wow, found a bug in scheduler.  The scheduler uninitialized itself
          in some circumstances even if threre were timeout tasks, though not
          IO tasks, but tasks anyway.  Now fixed.

        * Defined SilcServerConnection structure to hold connection specific
          stuff about directly connected servers and routers.  The definition
          is currently in silcd/server_internal.h.  I thought about having
          a bit more important role fro this struct but for now it is used
          only when connecting to other server (or router actually).

        * Added connecting retry support in server when connecting to
          router(s).  The retry feature implement exponential backoff
          algorithm.  Also, added SilcServerParams structure to hold default
          parameters for server.  For now, it include these retry settings
          and are hard coded.  After server is moded to be as Silc Server
          Library this structure will be more important.

Sun Nov  5 22:28:44 EET 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Changed client librarys channel->clients table to SilcList and
          changed code accordingly.

Thu Nov  2 16:28:01 EET 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Changed client's channel table to SilcList and changed code
          accordingly.  Also changed SilcChannelClientEntry to include back-
          pointer to the channel so that client entry can use that structure
          as list as well and we have fast cross-reference to the channel.
          This change dramatically decreased the complexity of channel
          handling with client entry and vice versa (removed one extra
          loop when searching for channel entry from many functions).

        * Changed server->sim from table to SilcDList and changed code
          accordingly.

        * NAMES command can now be used from user interface.  It will show
          the user list on the channel, neatly.

        * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
          Code now saves realname of the user if it becomes available.

        * Renamed configure.in to configure.in.pre and made ./prepare
          script to automatically add correct version string to
          configure.in which it creates from configure.in.pre.

Wed Nov  1 17:21:26 EET 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * NAMES command reply now shows users mode with the nickname when
          joining to channel.

        * Moved silc_client_ch[u]mode[_char] functions from
          silc/clientutil.[ch] to lib/silcclient/client.[ch].  Though, that
          place sucks, they are utility functions and should be in some
          other file.

        * Fixed some unsigned int's to unsigned short's.  Patch by cras.

        * Fixed contrib/getopt*.[ch] to not require config.h.  Patch by
          cras.

Tue Oct 31 20:10:37 EET 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Updated README.

        * Added TRQ (efficient deque and list library) into lib/trq.  This is
          a very good list library that is currently used in the SILC.  Defined
          SilcList API over the library because I didn't like the API very
          much.  See lib/trq/silclist.h for the API and examples of how to
          use the API.  Fixed various places in the code to use the new
          SilcList API. The SilcList is meant for lists that has a structure
          already defined as a list.  It is not suitable to add just some
          context to the list (in TRQ, the context is the list actually).

          So, I defined SilcDList that can be used for the purpose where
          predefined list structure does not exit.  This can be used as
          such list.  Now some context just can be added to the SilcDList.
          Currently this list is not used in the SILC just yet, though there
          are a lot places where this can replace dynamically allocated
          tables and I will fix these places, later, to use SilcDList.
          See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
          and use TRQ internally).

          Also fixed some annoying warning messages that the original TRQ
          code generated.  Also minor changes to TRQ's Makefile.in.

        * Added support for querying by Client ID to both WHOIS and
          IDENTIFY commands into server, as required by the protocol.

        * Removed method function pointers from SilcBuffer structure. They
          weren't used to anything and just increased the context size for
          no good reason.  This change also made silc_buffer_alloc and
          silc_buffer_free functions inline functions.

        * Disabled command flooding detection support until it's fixed so
          that it accepts commands in but does not execute them more than once
          in two seconds.

        * Added silc_net_localhost(), to return local hostname, into
          lib/silcutil/silcnet.[ch].  Also added client->hostname pointer
          that must be initialized before calling silc_client_init.

        * Added new function: silc_server_send_notify_on_channels to send
          notify messages to all channels client has joined.  It is assured
          that the message is sent only once per client.

        * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
          lib/silcutil/silcutil.[ch] as silc_format function.  The new
          function is generic and is used by server as well, not only by
          the logging routines.

        * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
          the provided version string was not acceptable.  Added new function:
          silc_ske_check_version into lib/silcske/silcske.h.  The function
          must be implemented by the application (client or server) and it
          does not reside in the SKE library.  The function checks the version
          string remote end sent.

        * Added back pointers (to opaque context and to SilcSocketConnection)
          into SilcPacketContext structure into lib/silccore/silcpacket.h.

        * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
          duplicate packet context structure.

        * Changed `notify' client operation to send same arguments as client
          receives from server except for ID's.  ID's are mapped to correct
          ID entry and that is returned.  Also, if channel entry is not sent
          by server but the notify is for channel the channel entry is sent
          to application (otherwise application doesn't know that it is for
          channel (library gets it from packet's Destination ID)).

        * Added silc_client_remove_from_channels into client library to
          remove a client from all channels it has joined to.  Used when
          received SIGNOFF notify from server.  Added also new function
          silc_client_replace_from_channels to replace old ID entry with
          new ID entry on all channels.  Used when received NICK_CHANGE
          notify from server.

        * Fixed ID Cache list handling in silc_idlist_get_client in
          lib/silcclient/idlist.c.  Also, added silc_idlist_get_client_by_id
          to get (or query) client by ID.

        * Updated TODO list.

        * Added connection authentication status message defined by the
          protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
          support for these into the code in client and server side.

        * Added generic function silc_client_send_command to send any command
          with variable argument list.  Application should use this function
          to send commands if the command functions provided by the library
          does not suite for the application's user interface needs.

        * Added new `failure' client operation.  Application is notified about
          received failure packet if client is executing a protocol.  In this
          case the protocol's execution has failed.

        * Added SKE's end notify to send the SKE_SUCCESS notify message that
          is required by the protocol.

        * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
          packet from remote.  SILC_PROTOCOL_STATE_ERROR indicates local
          error at our end.

        * Added status flag to SilcSKE object to indicate realtime status
          of the SKE protocol.

        * Application receives now exactly same command reply arguments as
          the library receives from server.  However, if ID is received the
          corresponding ID entry is returned to the application (eg. Client
          ID is mapped to correct SilcClientEntry entry and that is returned).
          Changed command_reply client operation due to this change.

        * Changed all ID's in commands and in command replys as ID Payloads.
          Change affected both client and server side codes.

          All ID's sent in SILC network (with execption of ID's in SILC
          Packet header) are sent in ID Payload to support variable length
          ID's.

        * Server now notifies nick changes and notifies all clients on
          the channels about the new nickname (about the new Client ID,
          actually).

        * Implemented CMODE command to change channel modes. Supports all
          channel modes defined by the protocol specs except ban and invite
          lists. (Also, private channel key mode is supported but support for
          setting private channel key in client is missing, thus, this mode
          has no effect on client side (except that server requires that the
          client uses private channel key and normal channel traffic does not
          work anymore)).

          Also, invite mode works per se, but INVITE command does not work
          yet correctly, so you can set channel as invite only channel but
          inviting clients to the channel does not work (it is yet to be
          thought what's the best way to do it).

        * Added new command SILC_COMMAND_CUMODE to change user mode on the
          channel.  Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
          Implemented CUMODE command to change user's mode on the channel.
          Supports all modes defined by the protocol specs.

        * Added NAMES command reply to return users modes on the channel.

        * Removed unnecessary and slow ciphers from lib/silccrypt.

        * Set SO_KEEPALIVE option to connection sockets by default.

        * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.

        * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE.  Also,
          redefined the Notify Payload into protocol specs.

        * Added silc_id_payload_parse_id to get ID directly from raw
          ID payload data.

Mon Oct  9 20:57:02 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Changed SILC_COMMAND_IDENTIFY in protocol specification to
          accept searching by Client ID as well.

        * Added support for LEAVE and SIGNOFF notify types in client library.

        * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
          to parse ID Payload from raw data.

Sun Oct  8 19:33:08 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added flags parameter into silc_ske_assemble_security_properties
          function in lib/silcske/silcske.[ch].

        * Changed notify client operation to fit better for notify messages
          sent by server.  The notify payload received from server is now
          passed to the application (after parsing it to SilcNotifyPayload).
          It is application's responsibility to retrieve the arguments
          from the payload and show the message the way it wants.  The message
          sent by server is implementation specific.

        * Changed public keys to comply with the protocol specification.
          Old public keys are not supported anymore and are not compatible.

        * Removed nickname from Channel Payload as the latest draft removed
          it.  The client must resolve the nickname from the NAMES command
          reply received when it joined the channel.

          Also, changed all channel_xxxx_payload to channel_payload_xxxx.

Sat Oct  7 21:55:01 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed some errors in protocol specification drafts.

        * Created lib/silccore/silcnotify.c to implement Notify Payload
          encoding and decoding, lib/silccore/silcpayload.[ch] to implement
          generic payloads described by protocol specifications.  The file
          includes implementations for ID Payload and Argument Payload.

        * Changed Command Payload implementation to use the new Argument
          Payload.  Changed command_xxxx_payload to command_payload_xxxx
          to comply with SILC coding conventions.

        * Added suppport for Argument Payload handling in Notify Payload
          implementation as protocol requires it.  Added the new support
          into server and client lib as well.

Thu Oct  5 21:16:28 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added support for multiple nicknames on same channel.  [n] is
          added locally to the nickname if there are more than one same
          nicknames on the channel.

        * Server now sends all nicknames that matched WHOIS request.
          Client also shows the list received from server.

        * Added TOPIC command to client side.  User can now set and show
          current topic on channel.

        * Added MOTD command to client and server.  Also, server sends the
          motd when client connects to the server.

        * Changed version strings to comply ISO 8601.

Wed Oct  4 23:29:06 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed protocol error handling in client library.  It should now
          cope even if the SKE fails for some reason.

        * Made new protocol specification drafts for submitting to IETF.

        * Implemented TOPIC command to server in silcd/command.c.

        * Added two new notify types into lib/silccore/silcnotify.h:
          SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
          notify nickname change and topic setting/change on a channel.

        * API change of command_reply operation in client library.  The
          application gets now the status type received from server as well.

Sat Sep 30 16:57:42 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Removed the function just added to lib/silcutil/silcschedule.[ch].

        * Cras fixed and optimized the packet handling even further and
          it should work now.  Minor change to the prototype of function
          silc_packet_receive_process in lib/silccore/silcpacket.[ch].

Sat Sep 30 08:48:47 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added new function into lib/silcutil/silcschedule.[ch]:
          silc_schedule_with_fd to select() a specified fd.  The function
          returns after timeout expires or data arrives or goes.  The
          function is used by packet routines to wait that all data is
          received from network.

        * Fixed data reading from network in lib/silccore/silcpacket.c.
          The code now assures that all data is read from the fd and then
          continues packet processing.  This was a bug fix since the code
          used to drop some data in some circumstances.

        * Added new function into lib/silcclient/client.[ch]:
          silc_client_start_key_exchange to start key exchange after
          connection has been established to server.  The code internally
          now uses this funtion but its main purpose was to provide it
          for applications that perform their own connecting.  After
          application has created a connection it merely calls this
          function to start the key exchange between client and server.
          The library takes care of everything else after that.

          Updated also lib/silcclient/README to explain the usage of
          this new function.

        * Do not send to application information that connection has
          been established.  Application gets notified it by connect
          operation anyway.

Thu Sep 28 23:40:19 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Applied cras's patch to add silc_schedule_one function.  The
          function runs scheduler once and returns.

        * Fixed the scheduler after cras messed it up.  The timeout
          handling works now as it's supposed to work.

        * Added into lib/silccore/ silcnotify.h to include notify
          message types support.  Changed silc_server_send_notify*
          functions, in server.[ch], to support those new notify types.
          Added the support for the notify types into client library,
          as well.  Added new notify client operation into ops.h in
          lib/silcclient/.

        * Changed silc_server_packet_send_to_channel to send normal
          packets instead of just channel message packets.  The function
          is now used to send the notify packets to channels.  It is not
          used to send channel message packets anymore, as server never
          sends them anymore.

        * Added explicit casting into lib/silcutil/silcbuffmt.c to few
          va_arg()s as it seems to require it nowadays.  I guess, if SILC
          is compiled with older va_arg() the new code should work anyway.

Wed Sep 13 18:10:14 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Splitted core library.  Core library (lib/silccore) includes
          now only SILC protocol specific core (and common) components.
          Created new utility library (lib/silcutil) that includes more
          generic purpose stuff.  The stuff for util library was taken
          from the old core library.  This was minor and easy split.

        * Created SILC Client Library (lib/silcclient) that includes
          implementation of the SILC client without user interface.  This
          was major move from silc/ directory.  The code has been changed
          so that it is transparent towards the user interface.  The
          silc/ directory includes now the same user interface as before
          and it uses the new client library.  Read lib/silcclient/README.
          Basicly, the client library performs everything else related
          to SILC except user interface handling.  Also, configuration
          files are considered to be part of user interface and library
          does not handle them.

          This change also changed a lot of structures, function naming etc.
          Most important change was that SilcClientWindow object was
          renamed to SilcClientConnection in the client library.  Created
          also new file lib/silcclient/ops.h.  Also added new files
          silc/local_command.[ch] and silc/client_ops.[ch].

          All these changes were made to make it easier for user interface
          designers to create what ever user interface for the SILC client
          they want.

          It is also expected that the server will be moved to lib
          directory as well and SILC Server Library will be created;
          sometimes in the future.

        * Removed Local commands from lib/silccore/silccommand.h as
          they are application specific and new client library does not
          handle any of those anymore.

        * Several functions moved to lib/silcutil/silcutilc.[ch] from
          old client implementation in silc/.

        * Added support for callback functions in SILC_LOG_* macros.
          Application can now set its own callbacks that will be called
          instead of using the default functions that will always print
          the debug messages to stderr (or stdout).  Also, debugging can
          now be disabled by setting silc_debug to FALSE and re-enabled by
          setting it to TRUE.  Note, that logging will still work even
          if debugging is disabled.

          New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
          silc_log_reset_callbacks, silc_log_set_debug_callbacks and
          silc_log_reset_debug_callbacks.

        * To enable debugging in silc client one must give now -d
          option on command line.

        * Changed silc_schedule_init to automatically allocate task queues
          if they are not allocated before calling it.

Thu Sep  7 10:49:33 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added GMP 3.1 into math library.

Sun Aug 20 21:27:26 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
          a channel in SILC network.  The packet is used by servers and
          routers to notify other routers that user has left a channel.
          This little feature was missing until now.  Added the feature
          to protocol specification as well.

          Added functions: silc_server_send_remove_channel_user and
          silc_server_remove_channel_user into server.[ch].

        * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
          lib/silccore/silcpacket.h.  However, they are not implemented
          yet.

Sat Aug 19 23:04:16 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed joining to a channel and sending channel messages
          between server and router.  The channel message sending should
          now work inside a cell.

Tue Jul 25 20:46:13 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed the private message sending between server and router.
          The private message sending should now work inside a cell.

        * Added silc_server_replace_id into server.[ch] to replace
          existing ID in the SILC network.

        * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
          and silc_idlist_replace_server_id into idlist.[ch] in server.

Mon Jul 24 18:33:31 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed the server to server connections.  Server can again now
          connect to router.  Router to router connections probably does
          not work just yet.

Thu Jul 20 13:15:01 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added dynamic protocol registering support.  Now protocols can
          registered and unregistered on the fly.  Patch by cras.

Wed Jul 19 19:08:46 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added lib/contrib directory to hold routines that some platforms
          don't have but are needed by SILC.

        * Added getopt.c, getopt1.c and getopt.h from GNU C library
          into lin/contrib to provide getopt() and getopt_long() for
          those who don't have it.

Tue Jul 18 20:41:20 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added AWAY command to client.  When away message is set and
          client receives a private message packet the client automatically
          replies to the sender with the away message.

        * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin.  This
          bug seemed to be the cause of recent problems when compiling
          with gcc-2.95.

        * Added version detection support to SKE protocol specification
          and added the new changes to the SKE implementation as well.
          There were other minor changes in the SKE protocol as well.

          Many changes in lib/silcske/silcske.[ch] and in
          lib/silcske/payload.[ch].

        * Added ^U functionality, clear input line.  Patch from cras.

Mon Jul 17 23:33:26 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Mainly small bugfixes on core library.  Fixed some debugging
          logging and buffer overflow in silclog.c.

        * Updated config.sub and config.guess on the distribution tree.

Sat Jul 15 15:33:48 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added command lagging support in server. Client may execute
          commands now only once in two seconds.

Thu Jul 13 22:10:21 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Optimized packet reception. MAC computation and checking is now
          also more optimized.  A lot previously duplicated code is now
          used as generic by both client and server.

        * Fixed key pair generation in clientutil.c

Wed Jul 12 18:28:07 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added into lib/silccore/silcbufutil.[ch] new function;
          silc_buffer_realloc.

        * Moved generic packet sending/encryption functions to
          lib/silccore/silcpacket.[ch] from client and server.  Some
          rewriting of the functions.

        * Moved all generic packet reception/decryption functions to
          lib/silccore/silcpacket.[ch] from client and server.  The
          packet processing is now much cleaner in both client and server.
          These were major changes in both client and server.

        * Created many common functions in server to do packet sending.
          Previously code were duplicated a lot, this has been removed
          with these changes.

Tue Jul 11 20:27:26 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Rewrote major parts of the ID cache system.  Don't know
          whether it is better now or not but at least the API is more
          cleaner now.

        * Major rewrite on ID cache stuff on client because of the ID
          cache API changes.  Added idlist.c to client.

        * Also major rewrite on ID cache stuff on server as well.
          Major rewrite of idlist.[ch]. SilcXXXList's are now named
          SilcXXXEntry's.  We won't keep anymore idlist specific pointers
          in hand, instead they are all put into the ID cache system now.
          All server_idlist_* routines uses ID cache now instead of
          traversing its own lists (those lists does not exist anymore).
          SilcIDList though still exists.  Also, SilcXXXEntry's are
          now pointers.

        * Finally made the SKE implementation compliant to the protocol
          specification.  All mp integers are now binary encoded as
          opposed being HEX encoded.

        * Added lib/silcmath/mpbin.[ch].  Encoding mp intergers to and
          from binary data.

        * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
          functions: silc_[encode/decode]_pem.  Also added function
          silc_encode_pem_file to PEM encode with newlines ('\n') for
          saving into a file.

        * SILC public keys are now encoded either PEM or binary.  Same
          option is for private keys as well.  By default private keys
          are binary encoded and public keys PEM encoded.  Silly HEX
          encoding were removed.

        * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
          function to create fingerprints.

        * Fixed a bug in SHA1; does not change the original data anymore.

        * Partly implemented INFO command on client and server side.
          Fixed CLEAR command.  Changes to SERVER command; show current
          server(s) when giving command without arguments.  Added
          VERSION command to client.

        * Added check to server that unregistered connections cannot
          execute commands (unless it is specificly allowed).

Thu Jul  6 18:12:24 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Fixed screen refresh.

        * Fixed channel joining bug from client.  On some circumstances
          client tried to join to a channel it had already joined.

        * Added public key verification process into client's protocol.c.
          The client now verifies the public key from user and saves
          it into ~./silc/serverkeys/ directory.

          Added into: clientutil.[ch]: silc_client_verify_server_key.

        * Changed SKE protocol's silc_ske_initiator_finish function
          to accept callback function that verifies the received public
          key.  Removed old silc_ske_verify_public_key function.

Wed Jul  5 19:19:02 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
          silc_pkcs_private_key[_data]_set.

        * Made the password and public authentication more cleaner in
          server's protocol.c.

        * Removed historic and obsolete protocol `channel_auth' from
          both client and server.

        * Removed wrong way of sending command status messages from
          server to client in server's command.c.  The old way violated
          protocol specification.

          Changes to silccore/silccommand.[ch]: removed
          silc_command_encode_status_payload -> not needed anymore,
          changed silc_command_encode_payload_va to accept extra
          argument on variable argument list.  The argument type must
          now be provided to the function.  Also, added new function:
          silc_command_encode_reply_payload_va which is same as
          normal command_encode_payload_va except command status type
          is provided as extra argument.

Tue Jul  4 18:26:39 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added ~./silc directory handling.  The directory includes the
          public and private keys for the client.

          Added silc_client_check_silc_dir, silc_client_create_identifier
          and silc_client_load_keys.

        * Implemented SILC protocol compliant public key.  Added public
          and private key saving to and loading from files.

          Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
          silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
          silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
          silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
          silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.

          Implemented: silc_pkcs_save_[public/private]_key[_data] and
          silc_pkcs_load_[public/private]_key.

Mon Jul  3 18:51:27 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added silc_server_get_route (route.[ch]) to get connection
          data for the fastest route for given ID.

        * Implemented INVITE command on client and server.  The command
          were re-defined in the SILC Protocol Specification and the
          implementation now complies with the specification.

        * Implemented PING command on client and server.

        * Implemented NAMES command on client and server.  The server side
          supports currently only normal server not router server yet.
          Some changes to NAMES definition in SILC protocol specification.

Sun Jul  2 18:23:01 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Implemented LEAVE command on client and server.

        * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
          again.  This change was made to the protocol as well.  Server
          should not violate the protocol specification anymore.

Fri Jun 30 14:03:26 EEST 2000  Pekka Riikonen <priikone@poseidon.pspt.fi>

        * Added SOCKS4 and SOCKS5 support to SILC client.  SOCKS5
          was tested.  SOCKS4 was not but should work anyway.
