+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
projects / silc.git / blobdiff
