8 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
9 to avoid collisions with other libraries using same type names
12 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
14 * Added `prefer_ipv6' argument to the functions
15 silc_net_gethostbyname[_async]. If it is TRUE it will return
16 IPv6 address over IPv4. If FALSE IPv4 address is returned
17 even if IPv6 address was found. Affected files
18 lib/silcutil/silcnet.[ch].
20 * Added support silc_net_create_connection[_async] to fallback
21 to IPv4 address if IPv6 address could not be used (like if

34 application does not need to define them. Affected file
35 includes/silcincludes.h.
37 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
38 old name went against naming convention. Applications now
39 include "silcclient.h" instead of "clientlibincludes.h".
40 Removed includes/clientlibincludes.h, it is redundant now.
42 * Renamed includes/version.h to silcversion.h.
44 * Added really preliminary support for OS/2 into the util
45 library. Only thread & mutex API is implemented, others
46 are still to be implemented. Created the lib/silcutil/os2/
47 directory. Created also file includes/silcos2.h.
49 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

80 * Added `user_count' to the SilcChannelEntry which now tells the
81 number of users on the channel. The user count is now saved
82 in normal server of global channels as well. Affected files
83 silcd/server.c, idlist.h, packet_receive.c and command.c.
85 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to

99 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
101 * ROBOdoc documented the lib/silcske/silcske.h, and improved
102 the SKE interface a bit.
104 * Fixed padding problem in PKCS#1. The padding was not actually
105 random since the random number generator was used incorrectly.
106 This security bug affects only when encrypting with PKCS#1, and
107 it is not currently used at all in SILC. SILC only use signing
108 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
110 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

176 * Added new configuration options and blocks:
177 keepalive_secs, reconnect_count, reconnect_interval,
178 reconnect_interval_max, reconnect_keep_trying and
179 require_reverser_lookup. Added ConnectionParam block, and

184 whether given configuration value has been given already.
186 Affected files silcd/serverconfig.[c], server.[c].
188 * Splitted the doc/example_silcd.conf.in. Separated the crypto
189 algorithm parts and created new file silcalgs.conf, that
190 is now included from the example_silcd.conf.in.
192 * Optimized the silc_server_connect_to_router_second to take
193 the connection configuration object from the SilcServerConnection
194 object instead of finding it during the connecting phase.
195 Added the configuration object to SilcServerConnection struct.
196 Affected files silcd/server_internal.h, server.c.

220 authentication to be set at the same time.
222 Added `prefer_passphrase_auth' setting in config file which
223 can be used to set to prefer passwd auth if both passwd and
224 public key is set. If not set, public key is preferred.
225 This has effect only when being initiator (responder will try
228 Added support for authentication with passphrase and public key
229 at the same time. The passphrase is tried first always since
230 it is faster to check.
232 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
234 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

280 * Fixed the file transfer's key agreement payload to include
281 zero port also if the hostname is NULL because it could not
284 Call file transfer monitor callback now also if error occurs
285 during key agreement protocol.
287 Changed the silc_client_file_send interface to return the
288 SilcClientFileError instead of session id. The session ID
289 is returned into pointer provided as argument.

308 * Fixed the channel message payload decryption in the function
309 silc_channel_message_payload_decrypt to not modify the original
310 buffer before it is verified that the message decrypted
311 correctly. Otherwise, next time it is called with correct
312 channel key it won't encrypt since the payload is corrupted.
313 Affected file lib/silccore/silcchannel.c.
315 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

329 become invalid in the callback but it was referenced after
330 the callback returned.
332 Do not allow auto rehashing of hash table during the
333 silc_hash_table_foreach operation, for same reasons as it is
334 not allowed for SilcHashTableList. Affected files are
335 lib/silcutil/silchashtable.[ch].
337 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

358 users list to SilcHashTable. The affected files are
359 lib/silcclient/idlist.[ch].
361 * Fixed a bug in hash table tarversing. While the hash table
362 is traversed with SilcHashTableList the table must not be
363 rehashed. It is now guaranteed that auto rehashable tables
364 are not rehashed while tarversing the list. Also defined that
365 silc_hash_table_rehash must not be called while tarversing
366 the table. Added function silc_hash_table_list_reset that must
367 be called after the tarversing is over. The affected files are
368 lib/silcutil/silchashtable.[ch].
370 * Changed all hash table traversing to call the new
371 silc_hash_table_list_reset in server and in client library.
373 * Added function silc_client_on_channel to return the
374 SilcChannelUser entry if the specified client entry is joined

394 * Create the key in JOIN command of the router did not return
395 the channel key, added check for this. Affected file is
398 * Fixed a channel ID update bug in JOIN command reply. Do
399 not directly upgrade the ID but call the function
400 silc_idlist_replace_channel_id if the ID was changed.
401 Affected file silcd/command_reply.c.
403 * Fixed memory leaks from command calling if it would fail.
404 Affected file silcd/command.c.

431 functions. Affected file silcd/server.c.
433 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
434 which ID was changed. This way the router will send the
435 user list for the channel again, and server won't be in
436 desync in some rare circumstances. Affected file is
437 silcd/packet_receive.c.
439 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

549 the client becoming valid after the server becomes back
550 online. Affected file silcd/server_util.c.
552 * Added `sock_error' field into the SilcSocketConnection
553 context. When error occurs during socket operation (read
554 or write) the error is saved. Added also new function
555 silc_socket_get_error to return human readable socket error
556 message. Affected files are lib/silcutil/silcsockconn.[ch],

563 * Fixed the `created' channel information sending from router
564 to server in JOIN command. Checks now whether the channel
565 really was created or not and set it according that.
567 Fixed the JOIN command to use the client entry's current
568 ID during the joining procedure instead of the one it sent
569 in the command (it is checked though), since it can change
570 between the packet processing and command processing, and
571 would just case unnecessary pain in the client end. Affected
572 file silcd/command.c.
574 * Fixed a channel key payload sending to use correct channel
575 ID when the server was forced to change the channel's ID by
576 router. Router sent the key payload with the old Channel ID.
577 Affected file silcd/packet_receive.c.
579 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
581 * Call silc_server_save_channel_key only if the key payload
582 was provided in the JOIN command's command reply. Affected
583 file silcd/command_reply.c.
585 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
587 * Fixed silc_mp_sizeinbase to return the value correctly with
588 MPI. Affected file lib/silcmath/mp_mpi.c.
590 * Fixed the stop_server signal to correctly stop the scheduler
591 and gracefully stop the server when SIGTERM or SIGINT signals
592 are received. Affected file silcd/silcd.c.
594 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
596 * Simple handling of TERM and HUP signals. Also added some log
597 flushing call around. Affected file is
600 * Fixed small bugs in silclog.c. Now buffering output will take
601 effect after 10 seconds since startup: This will ensure that
602 no important startup messages are lost. Also output redirection
603 will preserve original format ([Date] [Type] message).
604 Affected file is lib/silcutil/silclog.c.
606 * Added two options to the config file, in the logging section:
607 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
608 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
610 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
612 * Do not print the warning about log files not being initialized
613 more than once to avoid excess logging. Affected file is
614 lib/silcutil/silclog.c.
616 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
617 the SIM copying in make install in Makefile.am.pre.
619 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
621 * Rewritten silclog APIs. Globally interesting changes follows:
622 silc_log_set_files() changed to silc_log_set_file().
623 silc_log_set_callbacks() changed to silc_log_set_callback().
624 ROBOdoc documented silclog header file.
625 SilcLogCb now returns bool to wether inihibit the default
626 handler or not (to keep the old behaviour return always TRUE).
627 The new APIs should also fix the problem of the
628 silcd_error.log file that was written in the current directory.
631 Log files streams will remain opened after silc_log_set_file()
632 call, means less CPU usage notably on high traffic servers.
633 File streams are now full buffered, and flushed to the disk
634 every 5 minutes, lesses HD activity and CPU usage.
635 Messages can be redirected, allowing admins to configure
636 one single logfile for all server messages.
637 the silc_log_quick global variable to activate fast-logging.
638 Affected files lib/silcutil/silclog.[ch]
640 * Changed some code to conform new silclog APIs. Affected
641 files are doc/example_silcd.conf.in, silcd/server.c
642 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
645 * Fixed a memory leak that could occur in some situations.
646 Affected file silcd/serverconfig.c.
648 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
650 * Added the silc_client_del_client to remove the client from
651 all channels as well. Affected file lib/silcclient/idlist.c.
653 * Fixed the client library to correctly remove the client
654 from all channels when the client entry is being destroyed.
655 Affected file lib/silcclient/client_notify.c, command.c.
657 * Added auto-nicking support to the client library. If the
658 applicatio now sets client->nickname it will be sent to the
659 server after connecting by the library. This way for example
660 SILCNICK (or IRCNICK) environment variables will have effect
661 and always change the nickname automatically to whatever
662 it is wanted. Affected file lib/silcclient/client.[ch].
664 * Renamed silc_server_command_bad_chars to the
665 silc_server_name_bad_chars and moved it to the
666 silcd/server_util.[ch]. Added also new function
667 silc_server_name_modify_bad to return nickname that
668 includes bad characters as new nickname without those
669 bad characters. This check and modify is now used in
670 silc_server_new_client when the username is initially set
671 as nickname, so it must be checked to be valid nickname.
672 Affected file silcd/packet_receive.c.
674 * The nickname length is now taken from the packet for real
675 and not trusted to strlen() since it clearly can return
676 wrong length for nickname including bad characters. This
677 also applies to channel names. Affected file silcd/command.c.
679 * Removed the lib/silcsilm/modules directory. Modules are now
680 compiled into the lib/silcsim. Fixed the copying of the
681 modules to follow symbolic links in Makefile.am.pre.
683 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
685 * Fixed silc_string_regexify list creation. Fixes bugs with
686 BAN and INVITE commands in server. The affected file is
687 lib/silcutil/unix/silcunixutil.c.
689 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
691 * Removed the command destructor entirely from the server's
692 command and command reply routines. It is not needed, and
693 its usage was buggy and caused crashes. Affected files are
694 silcd/command[_reply].[ch].
696 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
698 * Cancel protocol and NULL sock->protocol if timeout
699 occurred during protocol. Affected file silcd/server.c.
701 * Cancel protocol timeouts always before calling the final
702 callback, to assure that after final callback is called
703 no other state will be called for the protocol anymore.
704 Affected file silcd/protocol.c.
706 * Print error log if incoming connection configuration could
707 not be found. Affected file silcd/server.c.
709 * Fixed JOIN command to correctly save the founder mode
710 to the client on normal SILC server, when the channel
711 was created by the router. Affected file silcd/command.c.
713 * Fixed LIST command (hopefully) to send correct reply
714 packets. Affected file silcd/command.c.
716 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
718 * The silc_packet_receive_process now returns FALSE if the
719 read data was invalid packet, and TRUE if it was ok.
721 The server now checks that if unauthenticated connection
722 sends data and its processing fails the server will close
723 the connection since it could be a malicious flooder.
725 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
727 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
729 * Make sure the warning about error opening a log file is
730 printed only once and not everytime it fails (produces
731 too much useless log). Affected file lib/silcutil/silclog.c.
733 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
735 * Made the silc_server_daemonise() function more readable.
736 Affected file silcd/server.c.
738 * Pid file is now optional, the user may comment it out from
739 the config file. Removed define SILC_SERVER_PID_FILE, we
740 don't need a default any longer. Affected file
741 configure.in.pre, lib/Makefile.am.pre.
743 * Make some use of the pid file. The server now dies at startup
744 if it detects a valid pid file on his path. The server would
745 die anyway in this circumstance, because of the bind() failure.
746 Affected file silcd/silcd.c.
748 * No longer compiling lib/dotconf.
750 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
752 * Fixed JOIN command parsing not to crash. Affected file
753 lib/silcclient/command.c.
755 * Fied the NICK_CHANGE notify to add the new client entry
756 even it is resolved. This removes an <[unknown]> nick
757 thingy bug in the client. Affected file is
758 lib/silcclient/client_notify.c.
760 * Do not try to allocate 0 bytes (efence does not like it)
761 in lib/silccore/silccomand.c when encoding payload.
763 * Do not take IRCNICK as nickname in Irssi SILC client since
764 it is not possible to set nickname before hand connecting
765 the server (TODO has an entry about adding auto-nicking
768 * Changed the silc_server_command_pending to check whether
769 there already exists an pending entry with the specified
770 command, command identifier and pending callback. This is
771 to fix IDENTIFY and WHOIS related crashes that may register
772 multiple pending commands with same identifier. Affected
773 file silcd/command.c.
775 * Fixed the server to reconnect to the router even if it
776 was already reconnecting and EOF was received. This to
777 fix a possibility that the server wouldn't ever try to
778 auto-reconnect to the router. Affected file silcd/server.c.
780 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
782 * Fixed the server's password authentication to use the
783 length of the locally saved password, and not the one
784 sent in the packet. Affected file silcd/protocol.c.
786 * Fixed same password authentication problem in the
787 Authentication Payload handling routines in
788 lib/silccore/silcauth.c.
790 * Yet another password authentication problem fixed with
791 channel password handling in silcd/command.c.
793 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
795 * If first character of string in silc_parse_userfqdn is '@'
796 then do not parse it. Affected file is
797 lib/silcutil/silcutil.c.
799 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
801 * Fixed minor bug in IDENTIFY command reply sending, which
802 caused various weird problems during JOIN when it was
803 resolving names for users. Affected file silcd/command.c.
805 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
807 * Fixed the IDENTIFY command reply sending to chech better valid
808 clients. It was possible to send incomplete list of replies.
809 Affected file silcd/command.c.
811 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
813 * Added silc_client_command[s]_[un]register functions now to
814 dynamically register the commands in client library. Removed
815 the static table of commands. This allows the client library
816 to call commands without causing the application to know about
817 what commands library has called.
819 Removed the INFO command reply kludge to detect when the command
820 was called by library. Now library use its own command reply
821 function for INFO command.
823 Added function silc_client_command_call to call a command.
824 Application can use it to call command, not access the structure
827 Now all commands that are sent by the client library (not
828 explicitly sent by application) use own command reply functions.
830 Affected files around lib/silcclient/ and in
831 irssi/src/silc/core/.
833 * Fixed the WHOIS command reply sending to chech better valid
834 clients. It was possible to send incomplete list of replies.
836 Fixed the WHOIS and IDENTIFY to send the request to router
837 if normal server did not do it and did not find any results.
839 Affected file silcd/command.c.
841 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
843 * Moved the internal data from SilcClient context into its
844 own file, not accesible to application. Affected files
845 lib/silcclient/client.h and lib/silcclient/client_internal.h,
846 and other files in client library.
848 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
850 * Added doc/examples installation target in Makefile.am.pre.
853 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
855 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
856 commands the found client entry will be removed from the
857 cache, after notifying application about the error. Affected
858 file lib/silcclient/command_reply.c.
860 * Changed the /MSG to check for exact nickname user gave, and
861 not let `nick' match `nick@host' if it is only one found. Now,
862 user must type the exact nickname (like nick@host2) even if
863 there are no more than one same nicks found. This is to avoid
864 a possibility of sending nickname to wrong nickname since
865 `nick' could match `nick@host'. Affected file is
866 irssi/src/core/silc-servers.c.
868 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
870 * Do not print "you are now server operator" or similar when
871 giving /away command. Affected files are
872 irssi/src/silc/core/client_ops.c, silc-servers.h.
874 * Made the silc_server_command_pending_error_check to send
875 the same command reply payload it received back to the
876 original sender of the command. This way all arguments
877 that was received by the server will be received by the
878 client too. Affected file silcd/command.c.
880 * Added the silc_idcache_add to return the created cache entry
881 to a pointer. Affected file lib/silccore/silcidcache.[ch].
883 * Add global clients to expire if they are not on any channel.
884 This is because normal server will never know if they signoff
885 if they are not on any channel. The cache expiry will take
886 case of these entries. This is done by normal servers only.
887 The affected files are silcd/command_reply.c,
888 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
890 * If server receives invalid ID notification for WHOIS or
891 IDENTIFY and the ID exists in the lists, it is removed.
892 Affected file silcd/command_reply.c.
894 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
895 in client then client entry that it matches is searched and
896 the nickname is printed on the screen for user. Affected
897 file irssi/src/silc/core/client_ops.c.
899 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
901 * Use cache entry expire time in the LIST command reply to
902 purge old entries from the cache after the LIST command
903 reply has been received. This way we don't have non-existent
904 entries in the cache for too long. Affected file is
905 silcd/command_reply.c.
907 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
909 * If we are normal server, and we've not resolved client info
910 in WHOIS or IDENTIFY from router, and it is global client,
911 we'll check whether it is on some channel. If it is not
912 then we cannot be sure about its validity and will resolve it
913 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
914 file silcd/command.c.
916 * Search channel by name (if possible) rather than by ID
917 in IDENTIFY command's command reply. Affected file is
918 silcd/command_reply.c.
920 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
922 * Distribute to the channel passphrase in CMODE_CHANGE notify.
923 Updated specs and implemented it. Affected file silcd/command.c,
924 silcd/packet_send.c and silcd/packet_receive.c.
926 * Implemented the <founder auth> payload handling in the JOIN
927 command. If provided all conditions for channel joining
928 except requirement to provide correct passphrase can be
929 overrided by the channel founder. Updated the protocol specs.
930 Affected file silcd/command.c.
932 Added support for founder auth in JOIN command in client
933 library. Fixed the parsing of the JOIN command now to support
934 all options as they should be. The affected file is
935 lib/silcclient/command.c.
937 * Optimized the WHOIS and IDENTIFY commands to send the request
938 to router only if it includes nicknames or other names. If
939 they include only IDs then check the local cache first before
940 routing. Affected file is silcd/command.c.
942 * Added channels topic announcements. Affected file is
943 silcd/packet_receive.c and silcd/server.c.
945 * Fixed the silc_server_send_notify_topic_set to really destine
946 the packet to channel. Affected file silcd/packet_send.c.
948 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
949 library. Affected file lib/silcclient/client_notify.c.
951 * Added UMODE announcements. Affected file silcd/server.c.
953 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
955 * Memory leak fixes in:
957 lib/silcutil/silcsockconn.c
958 lib/silcske/silcske.c
961 lib/silccrypt/silcpkcs.c
962 lib/silccore/silccommand.c
963 lib/silccore/silcidcache.c
968 * ROBOdoc documented the lib/silcske/groups.h file and a
969 bit changed the interface for better.
971 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
973 * Update the client entry context in the ID cache after
974 nick change. Affected file lib/silcclient/command.c.
975 Fixes the CUMODE command when regaining founder privileges,
976 and a little WHOIS problem.
978 * Fixed silc_net_gethostbyname to correctly call the
979 inet_ntop. Affected file lib/silcutil/silcnet.c.
981 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
983 * Added IPv6 support checking to the configure.in.pre, added
984 also --enable-ipv6 option to override the check. Affected
985 file configure.in.pre.
987 * The silc_thread_create now calls the start function
988 directly if threads support is not compiled in. Removes
989 ugly #ifdef's from generic code. Affected files are
990 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
992 * Added silc_net_gethostby[name/addr]_async to asynchronously
993 resolve. Affected files are lib/silcutil/silcnet.[ch].
995 * Added support for rendering IPv6 based server, client and
996 channel IDs. Affected file lib/silcutil/silcutil.c.
998 * Added support for creating IPv6 based server IDs. Affected
999 file is silcd/serverid.c.
1001 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1003 * Added silc_net_gethostby[addr/name] into the
1004 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1005 routines. Added silc_net_is_ip[4/6]. Affected file is
1006 lib/silcutil/unix/silcunixnet.c. All routines that take
1007 address as argument now supports both IPv4 and IPv6 addresses.
1009 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1011 * Fixed LIST command reply sending in server. Affected file
1014 * Server now sends the kicker's client ID in the KICK notify
1015 to the kicked client. Affected file silcd/command.c.
1017 * The client library now parses the kickers client ID and
1018 UI displays it. Affected files lib/silcclient/client_notify.c
1019 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1021 * Made all payload parsing function prototypes consistent.
1022 They all take now const unsigned char * and uint32 pair as
1023 the payload data instead of SilcBuffer. Changes all around
1024 the source tree. Other unsigned char* -> const unsigned char*
1025 changes around the tree as well.
1027 * Optimized SFTP client and server packet sending not to
1028 allocate new buffer for each packet but to recycle the
1029 first allocated buffer. Affected files are
1030 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1032 * Optimized the SFTP client to use SilcList instead of
1033 SilcDList for requests, because it is faster. Affected file
1034 is lib/silcsftp/sftp_client.c.
1036 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1037 into lib/silccore/silcid.[ch].
1039 Renamed silcpayload.[ch] into silcargument.[ch].
1041 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1043 * If client entry is deleted with active key agreement
1044 session, abort the session.
1046 The silc_client_abort_key_agreement now calls the completion
1047 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1049 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1052 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1054 * Don't use __restrict in older GCC's. Affected file is
1055 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1057 * silc_net_localhost now attempts to reverse lookup the
1058 IP/hostname. Affected file lib/silcutil/silcnet.c.
1060 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1061 command. It can be used to gain founder privileges at
1062 the same time when joining the channel.
1064 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1065 kicker's client ID as well. Updated protocol specs.
1067 Defined that the server must send SILC_COMMAND_IDENTIFY
1068 command reply with error status to client who sent
1069 private message with invalid client ID.
1071 Updated the protocol specification.
1073 * Added silc_server_send_command_reply to send any
1074 command reply. Affected file silcd/packet_send.[ch].
1076 * Added silc_id_payload_encode_data to encode ID payload
1077 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1079 * The server now send IDENTIFY command reply with error
1080 status if client ID in private message is invalid. Affected
1081 file silcd/packet_receive.c.
1083 * Save the server key file with server's IP address in
1084 the filename instead of hostname. The affected file is
1085 irssi/src/silc/core/client_ops.c.
1087 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1089 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1092 * Added libtool support for compiling shared objects in
1093 lib/silcsim. Affected file configure.in.pre and
1094 lib/silcsim/Makefile.am. Original patch by cras.
1096 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1098 * Pid file configuration, and server's config file fixes
1099 patch by toma. Updated CREDITS file.
1101 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1103 * Fixed silc_client_channel_message to not try to decrypt
1104 the message twice if it resolved the destination client
1105 information. This could cause of dropping one channel
1106 message. Affected file lib/silcclient/client_channel.c.
1108 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1110 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1111 lib/silcclient/client.c. This function is used when the SILC
1112 Client is run under some other scheduler, or event loop or
1113 main loop. On GUI applications, for example this may be
1114 desired to used to run the client under the GUI application's
1115 main loop. Typically the GUI application would register an
1116 idle task that calls this function multiple times in a second
1117 to quickly process the SILC specific data.
1119 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1121 * Fixed silc_server_drop() for dropping the supplementary
1122 groups as well, this could cause a security hole on some
1125 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1127 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1130 * Write PID file after dropping privileges. Added -F option
1131 to run server on foreground. A patch by debolaz.
1132 Affected files silcd/server.c, silcd/silcd.c.
1134 * Fixed MOTD to return the MOTD file server name. Affected
1135 file silcd/command.c.
1137 * Added INFO command reply handling to the Irssi SILC Client.
1138 Affected file irssi/src/silc/core/client_ops.c.
1140 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1142 * Fixed the silc_idcache_list_* routines to really support
1143 the dynamic list. Fixes a crash. Affected file is
1144 lib/silccore/silcidcache.c.
1146 * Fixed the LIST command reply to really call LIST command's
1147 pending callbacks. Affected file silcd/command_reply.c.
1149 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1151 * Update conn->local_entry->nickname after giving NICK
1152 command. Affected file lib/silcclient/command.c.
1154 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1156 * Added the [pid] option to the silcd configuration file
1158 Affected files: serverconfig.[ch] and silcd.c
1160 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1162 * Save fingerprint in WHOIS command reply in server.
1163 Affected file silcd/command_reply.c.
1165 * Fixed NICK commands pending callback registration.
1166 Affected file lib/silcclient/command.c.
1168 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1170 * Use ++server->cmd_ident when sending commands in server,
1171 instead of random number. Affected file silcd/command.c.
1173 * Fixed GETKEY command reply to call actually GETKEY pending
1174 command callbacks. Affected file silcd/command_reply.c.
1176 * A bit stricter check for nicknames. Check for same nickname
1177 in NICK command also. Affected file silcd/command.c.
1179 * Do not call INFO command everytime client ID changes, only
1180 during first connecting. Affected file lib/silcclient/client.c.
1182 * Set the new nickname only after successful command reply for
1183 NICK command is returned by server. Affected file
1184 lib/silcclient/command.c.
1186 * Remove nicknames from nicklist during server_signoff notify.
1187 Should fix /NAMES bit more. The affected file is
1188 irssi/src/silc/core/silc-channels.c.
1190 * Added `fingerprint' field to the SilcIDListData in the
1191 silcd/idlist.h to hold the fingerprint of the client's
1194 Send the fingerprint of the client's public key in WHOIS
1197 Affected files silcd/command.c, and silcd/idlist.[ch].
1199 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1200 create fingerprint from given data.
1202 * Show the fingerprint of the client's public key in WHOIS.
1203 Affected files irssi/src/module-formats.[ch] and
1204 irssi/src/silc/core/client_ops.c.
1206 * Format the multiple same nicknames also during JOIN and
1207 NICK_CHANGE notifys. Affected file is
1208 lib/silcclient/client_notify.c.
1210 * Do not print error on screen for invalid private message
1211 payload since it can come if someone is sending private
1212 messages with wrong key. Affected file
1213 lib/silccore/silcprivate.c.
1215 * Fixed multiple concurrent /PING crash. Affected file
1216 lib/silcclient/command.c.
1218 * Changed the wrong ID encoding. All IP addresses must be
1219 in MSB first order in encoded format. They were encoded
1220 wrong and was in LSB format. Affected files are
1221 silcd/serverid.c, lib/silcutil/silcutil.c.
1223 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1225 * Call the `connect' client operation through the scheduler
1226 in case of error. Affected file lib/silcclient/client.c.
1228 * Call the `failure' client operation even if the error
1229 occurred locally during a protocol. Affected file is
1230 lib/silcclient/protocol.c.
1232 * Added support of sending LIST command to router from normal
1233 server. This way normal server can get list of all channels
1234 in the network too. Fixed the channel list sending in the
1235 server too. Affected files are silcd/command.c, and
1236 silcd/command_reply.[ch].
1238 * Added silc_server_update_channels_by_server and
1239 silc_server_remove_channels_by_server. They are used during
1240 disconnection of primary router and in backup router protocol.
1241 Affected file silcd/server_util.[ch], silcd/server.c and
1242 silcd/server_backup.c.
1244 * Fixed channel adding to global list in IDENTIFY command
1245 reply in server. Affected file silcd/command_reply.c.
1247 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1249 * If the incoming packet type is REKEY or REKEY_DONE process
1250 that packet always synchronously. Fixes yet another MAC
1251 failed error on slow (dialup) connections. Affected file
1252 lib/silcclient/client.c and silcd/server.c.
1254 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1256 * Call check_version SKE callback for initiator too. Affected
1257 file lib/silcske/silcske.c.
1259 * Implemented fix for security hole found in the SKE that was
1260 fixed in the specification few days back; the initiator's
1261 public key is now added to the HASH value computation.
1262 Added backwards support for the old way of doing it too, for
1263 old clients and old servers. Affected file is
1264 lib/silcske/silcske.c.
1266 * Enabled mutual authentication by default in SKE. If initiator
1267 is not providing mutual authentication the responder will
1268 force it. This will provide the proof of posession of the
1269 private key for responder. The affected files are
1270 lib/silcclient/protocol.c and silcd/protocol.c.
1272 * Do not cache anymore the server's public key during SKE.
1273 We do mutual authentication so the proof of posession of
1274 private key is done, and if the server is authenticated in
1275 conn auth protocol with public key we must have the public
1276 key already. Affected file silcd/protocol.c.
1278 * Added new global debug variable: silc_debug_hexdump. If
1279 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1280 file lib/silcutil/silclog.[ch].
1282 * Fixed compilation warning due to char * -> const char *.
1283 Affected files lib/silcutil/silcnet.h, and
1284 lib/silccore/silcauth.[ch].
1286 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1288 * Fixed CMODE command when new channel key was created. If
1289 the creation failed the old key was removed. Next time giving
1290 same command would crash the server since the old key was
1291 freed already. Affected file silcd/command.c.
1293 * Fixed the silc_server_announce_get_channels to not crash
1294 on reconnect. Affected file silcd/server.c.
1296 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1298 * Added silc_log_set_debug_string function to set a regex
1299 string to match for debug output. Only the function names,
1300 or filenames matching the given debug string is actually
1301 printed. This way it is possible to filter out those debug
1302 strings that user is not interested in.
1304 Fixed a bug in silc_string_regexify.
1306 Affected files lib/silcutil/silclog.[ch], and
1307 lib/silcutil/unix/silcunixutil.c.
1309 * Changed the -d options in both server and Irssi SILC client
1310 to take the debug string as argument. Affected files
1311 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1313 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1315 * Added silc_hash_babbleprint to create a Bubble Babble
1316 Encoded fingerprint. The encoding is developed by Antti
1317 Huima (draft-huima-babble-01.txt), and it creates human
1318 readable strings out of binary data. Affected file
1319 lib/silccrypt/silchash.[ch].
1321 * Print the babble print now in addition of fingerprint as well
1322 in Irssi SILC client. Affected files are
1323 irssi/src/fe-common/silc/module-formats.[ch],
1324 irssi/src/fe-common/silc/core/client_ops.c.
1326 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1328 * Fixed a security problem found in SKE. The initiator's
1329 public key too is now added to the HASH hash value creation
1330 which is signed by the responder to create the SIGN value.
1331 This will prevent anyone in the middle to lie to the responder
1332 about the initiator's public key. If this is done now, the
1333 man in the middle will get caught. Updated the protocol
1336 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1338 * Better installation directory handling. Configure module
1339 paths and other paths automatically to example_silc* files
1340 in doc/. A patch by toma.
1342 * Fixed compiler warning from MPI library, and from SILC RNG.
1345 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1346 It can be configured with ./configure. A patch by toma.
1348 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1350 * Find correct make to use in prepare-clean. A patch by
1351 toma. Affected file prepare-clean.
1353 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1355 * Added irssi variables use_auto_addr, auto_bind_ip,
1356 auto_bind_port and auto_public_ip.
1358 * Changed the interface for silc_client_send_key_agreement
1359 in lib/silcclient/silcapi.h
1363 irssi/src/silc/core/silc-core.c
1365 lib/silcclient/silcapi.h
1366 irssi/src/silc/core/silc-channels.c
1367 lib/silcclient/client_keyagr.c
1370 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1372 * Added silc_pkcs_public_key_compare to compare two
1373 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1375 * Check that the client who set the founder mode on the
1376 channel is the same client that is giving the founder
1377 mode to itself. It is done by comparing the saved public
1378 key (it is saved even in the authentication is passphrase).
1379 Affected file silcd/command.c.
1381 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1383 * Do not process packet for disconnected socket connection.
1384 Affected file lib/silccore/silcpacket.c.
1386 * Process the DISCONNECT packet through scheduler in the
1387 client library. Affected file lib/silcclient/client.c.
1389 * Fixed the silc_client_packet_parse to not to increase
1390 the packet sequence number if the conn->sock and the
1391 current socket connection is not same. This can happen
1392 for example during key agreement when the conn includes
1393 multiple socket connections (listeners). Affected file
1394 lib/silcclient/client.c.
1396 * The sender of the file transfer request now provides also
1397 the pointer (listener) for the key exchange protocol. If
1398 the listener cannot be created then it sends empty key
1399 agreement and lets the receiver provide the listener.
1401 Added `local_ip' and `local_port' arguments to the
1402 silc_client_file_send. If they are provided they are used,
1403 if not then it will attempt to find local IP address, if
1404 not found or bind fails then the remote client will provide
1407 Affected files are lib/silcclient/client_ftp.c and
1408 lib/silcclient/silcapi.h.
1410 * Extended the FILE SEND command to support defining the
1411 local IP and port for key exchange listener. They are
1412 optional. Affected file irssi/src/silc/core/silc-servers.c.
1414 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1416 * Defined to WHOIS command reply the sending of fingerprint
1417 of the client's public key (if the proof of posession of the
1418 corresponding private key is verified by the server).
1419 Updated to the protocol specification.
1421 * Added support of receiving the client's public key's
1422 fingerprint in command reply in client library. Affected
1423 file is lib/silcclient/command_reply.c, and
1424 lib/silcclient/idlist.[ch].
1426 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1428 * Do not send over 128 chars long nickname to the server
1429 in NICK command. Affected file lib/silcclient/command.c.
1431 * Do not send over 256 chars long channel names to the server
1432 in JOIN command. Affected file lib/silcclient/command.c.
1434 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1436 * Assure that silc_server_close_connection cannot be called
1437 twice for same socket context. Affected file is
1440 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1442 * Send error message to application if opening file for
1443 writing during file transfer fails. Affected file is
1444 lib/silcclient/client_ftp.c.
1446 Remove all file transfer sessions for a client that we're
1447 removing from ID cache.
1449 Affected file is lib/silcclient/client_ftp.c.
1451 * Fixed silc_net_addr2bin to return correct address. Affected
1452 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1454 * Fixed file transfer session removing on signoff notify.
1455 Affected file irssi/src/silc/core/silc-servers.c.
1457 * Added the SilcClientFileError to be returned in the monitor
1458 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1459 Affected file lib/silcclient/silcapi.h.
1461 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1463 * Fixed a crash in silc_client_ftp_free_sessions and
1464 silc_client_ftp_session_free_client. Affected file
1465 lib/silcclient/client_ftp.c.
1467 * Added `disabled' field in the SilcChannelEntry in the server
1468 to indicate if the server entry is disabled. Affected file
1469 silcd/idlist.h, silcd/command[_reply].c.
1471 * SILC server adds now /var/run/silcd.pid everytime it is
1472 started. Affected file silcd/silcd.c.
1474 * Added silc_server_packet_send_clients to send a packet to
1475 the provided table of client entries. Affected file
1476 silcd/packet_send.[ch].
1478 * Fixed a crash in client resolving in client_prvmsg.c in
1479 client library. Affected file lib/silcclient/client_prvmsg.c.
1481 * Do not actually remove the client directly from ID cache
1482 during SERVER_SIGNOFF, but invalidate it. This way we
1483 preserve the WHOWAS info for the client. Affected file
1484 silcd/server_util.c.
1486 * Fixed SERVER_SIGNOFF notify handling in the server. The
1487 server is now able to process incoming SERVER_SIGNOFF notify
1488 for a server that it doesn't even know about. It will remove
1489 the clients provided in the notify. Affected file
1490 silcd/packet_receive.c.
1492 * Check for partial packet in data queue after every packet that
1493 was found from the queue. Return and wait for more data if
1494 there is partial data in queue. Affected file is
1495 lib/silccore/silcpacket.c.
1497 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1499 * Added SilcClietFileError enum to indicate error in
1500 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1501 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1502 Affected files lib/silcclient/silcapi.h and
1503 lib/silcclient/client_ftp.c.
1505 * Check that newsize in silc_buffer_realloc is larger than
1506 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1508 * Added better monitor of file transfers. It now monitors
1509 key agreement protocol during the file transfer too. Added
1510 error reporting too. Affected files
1511 irssi/src/silc/core/silc-servers.c,
1512 irssi/src/fe-common/silc/module-formats.[ch].
1514 * Wrote a help file for FILE command.
1516 * Added silc_rng_global_get_byte_fast to get not-so-secure
1517 random data as fast as possible. Random data is read from
1518 /dev/urandom if available and from the SILC RNG if not
1519 available. It is used in padding generation. Affected file
1520 lib/silccrypt/silcrng.[ch].
1522 * All packets in client library are now processed synchronously.
1523 Optimized packet processing a lot. Affected file
1524 lib/silcclient/client.c.
1526 * All server connection packets are processing synchronously
1527 now in server, to optimize packet processing. Affected file
1530 * Include files are installed now only in Toolkit distribution
1531 if make install is given. Affected files: all Makefile.am's.
1533 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1535 * Assure that silc_client_notify_by_server_resolve does not
1536 resolve the client information multiple times. If it cannot
1537 be found by the first it cannot be found at all. Affected
1538 file lib/silcclient/client_notify.c.
1540 * Fixed WHOWAS command reply calling. Affected file
1541 lib/silcclient/command_reply.c.
1543 * Removed all references to silc_idlist_get_client from the
1544 Irssi SILC client since that call is internal call used by
1545 the library. The Irssi SILC client will use now client
1546 retrieval functions found in silcapi.h.
1548 * Fixed a bug in resolving nickname info before sending
1549 private message. It used freed memory. Affected file
1550 irssi/src/silc/core/silc-servers.c.
1552 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1554 * Assure my_channels statistics cannot go negative in server.
1555 Affected files silcd/server.c, silcd/server_util.c.
1557 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

1569 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1571 * Added silc_net_localip to return local host's IP address.
1572 Affected file lib/silcutil/silcnet.[ch].
1574 * If key exchange or rekey protocol is active for a connection
1575 parse all packets syncronously since there might be packets
1576 in packet queue that we are not able to process without first
1577 processing packets before them. Affected file silcd/server,
1578 lib/silcclient/client.c.
1580 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1581 whether library should continue processing the packet.
1582 Affected file lib/silccore/silcpacket.h.
1584 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

1610 * Renamed silc_file_read and silc_file_write to functions
1611 silc_file_readfile and silc_file_writefile. Added function
1612 silc_file_open and silc_file_close. Affected files
1613 lib/silcutil/silcutil.[ch].
1615 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1617 * Resolve the client info when received private message or
1618 channel message for a client which nickname we don't know.
1619 Affected files lib/silcclient/client_prvmsg.c and

1628 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
1629 is incomplete and is being resolved, it won't be resolved
1632 Make sure also that USERS command reply does not resolve
1633 twice information. Affected file is
1634 lib/silcclient/command_reply.c.
1636 Make sure that silc_client_get_clients_by_list does not
1637 resolve twice same information.
1639 * Check for valid client->id in the silc_server_free_client_data.
1640 Affected file silcd/server.c.
1642 * Fixed /GETKEY nick@server not to crash if the server entry
1643 is not found. Affected file lib/silcclient/command.c.
1645 * Fixed the silc_server_check_cmode_rights to check the
1646 requested modes correctly. Affected file silcd/command.c.
1648 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
1650 * Better checks for non-printable chars in nick added.
1651 Affected file silcd/command.c.
1653 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1655 * Call the silc_server_udpate_servers_by_server in the
1656 primary router that comes back online in the backup resuming
1657 protocol. Otherwise it routes packets wrong. Affected file
1658 silcd/server_util.[ch], silcd/server_backup.c.
1660 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1662 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
1663 lib/silcutil/silcbuffmt.[ch].
1665 * Redefined the SILC packet header to include the padding
1666 length. Affected file lib/silccore/silcpacket.[ch].
1668 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
1669 length for maximum padding up to 128 bytes). Affected
1670 file lib/silccore/silcpacket.h.
1672 * Removed all backwards support for old 0.5.x MAC thingies.
1673 The SILC packet header change makes it impossible to be
1674 backwards compatible.
1676 * Send the ENDING packet with timeout in the backup resuming
1677 protocol. This is to assure that all routers has connected
1678 to the primary router. Affected file silcd/server_backup.c.
1680 * Changed the RNG to take the first IV from random data. It
1681 used to take it from zero actually. Changed the RNG also
1682 to use /dev/urandom during session. /dev/random is used
1683 in initialization. Affected file lib/silccrypt/silcrng.[ch].
1685 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1687 * Changed the SILC packet header to have the first two bytes
1688 (the packet length) encrypted. Affected files aroung the
1689 code tree, lib/silccore/silcpacket.[ch]. Removed the
1690 SilcPacketCheckDecrypt callback. It is not needed anymore
1691 since the silc_packet_receive_process will determine now
1692 whether the packet is normal or special.
1694 * Implemented the unidirectional MAC keys. Affected files
1695 lib/silcske/silcske.c, silcd/protocol.c and
1696 lib/silcclient/protocol.c.
1698 * Implemented the packet sequence number to the MAC computation.
1699 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
1700 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
1701 lib/silcclient/protocol.c.
1703 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1705 * Allow backup router to announce servers. All servers
1706 announced by backup router are added to the global list
1707 automatically. Update hte server's socket to our primary
1708 router also when backup router announces a server.
1709 Affected file silcd/packet_receive.c.
1711 * Do not update the client->router in the function
1712 silc_server_udpate_clients_by_server if the client is on
1713 global list. We might fail to find any specific server
1714 for locally connected clients and local cell clients. They
1715 should still use the `from' and not `to' as client->router.
1716 This fixes backup router resuming protocol. Affected file
1717 silcd/server_util.c.
1719 * Decrease channel statistics count only if the channel
1720 deletion worked. Affected files are silcd/server.c and
1721 silcd/server_util.c.
1723 * Added silc_server_update_servers_by_server to update origin
1724 of all server entries. Used during backup router protocol.
1725 Affected files silcd/server_util.[ch], silcd/server.c. and
1726 silcd/backup_router.c.
1728 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
1729 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
1730 silc_hmac_get_hash and silc_hmac_get_name. Affected file
1731 lib/silccrypt/silchmac.c.
1733 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1735 * Assure that router cannot reroute the same channel message
1736 to the sender. Affected file silcd/packet_receive.c.
1738 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1740 * Made better checks that the channel message is not sent
1741 to the router it came from. Affected file is
1742 silcd/packet_send.c. Fixed memory leak too.
1744 * Announce informations for incoming router connection, but
1745 only after checking if it is replaced by backup router.
1746 Affected file silcd/packet_receive.c.
1748 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1750 * Fixed the backup resuming protocol to work in multiple
1751 router environment. Affected file silcd/server_backup.c.
1753 * Route packet only to one router in the function
1754 silc_server_packet_send_to_channel. Affected file is
1755 silcd/packet_send.c.
1757 * Fixed silc_server_send_notify_dest to set the broadcast
1758 flag. Fixed the silc_server_send_notify_topic to actually
1759 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
1760 Affected file silcd/packet_send.c.
1762 * Changed the SFTP Filesystem interface. Changed the
1763 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
1764 the filesystem operation function. The SilcSFTPFilesystem
1765 is now a context that is allocated by all filesystem allocation
1766 functions and it already includes the operations structure
1767 and filesystem specific context. It is given as argument
1768 now to the silc_sftp_server_start. This made the interface
1769 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
1770 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
1772 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1774 * Changed the backup router adding and getting interfaces
1775 in the server. The router that will be replaced by the
1776 specified backup router is now sent as argument. Affected
1777 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
1780 * Added silc_net_addr2bin_ne to return the binary form of
1781 the IP address in network byte order. Affected files
1782 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
1784 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1786 * Check for existing server ID in silc_server_new_server
1787 and in silc_server_connect_to_router_final and remove the
1788 old entry if it exists. Affected file silcd/packet_receive.c,
1791 * Send the channel message always to only one router, either
1792 in upstream or downstream. Affected file is
1793 silcd/packet_send.c.
1795 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1797 * Wrote the definition of the backup resuming protocol to the
1798 protocol specification.
1800 * Removed one redundant channel key generation from normal
1801 server during joining procedure. Removed one redundant
1802 channel key sending from server to router during joining
1803 procedure. Affected file silcd/command.c.
1805 * Made minor bugfixes to the backup router resuming protocol.
1806 Affected file silcd/server_backup.c, server.c.
1808 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1810 * Added --disable-asm configuration option. Affected files
1811 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
1814 * Implemented the backup resuming protocol that is used to
1815 resume the primary router position in the cell after the
1816 primary router comes back online. Affected files
1817 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
1818 and silcd/server_util.[ch].
1820 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1822 * Sleep two (2) seconds after sending QUIT command to server.
1823 Affected file lib/silcclient/command.c.
1825 * Assure that if outgoing data buffer is pending do not force
1826 send any data. Affected file silcd/packet_send.c.
1828 * Assure that if outgoing data buffer is pending do not force
1829 send any data. Affected file lib/silcclient/client.c.
1831 * Implemented the backup router support when the primary router
1832 goes down. The servers and routers can now use the backup
1833 router as new primary router without loosing connectivity.
1835 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1837 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
1838 in the server to indicate disabled entry. All data read
1839 from the connection will be ignored and no data is sent
1840 for entry that is disabled. Affected files are
1841 silcd/idlist.h, silcd/server.c.
1843 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1845 * Created SFTP client and server test programs in the
1846 lib/silcsftp/tests directory.
1848 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1850 * Implemented memory filesystem (virtual filesystem) for
1851 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
1854 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1856 * Implemented the SFTP (SSH File Transfer Protocol) to the
1857 lib/silcsftp. It includes SFTP client and SFTP server
1860 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1862 * Moved lib/silccore/silcprotocol.[ch] to the
1863 lib/silcutil library.
1865 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
1866 take variable argument list pointer as argument. Affected
1867 file lib/silcutil/silcbuffmt.[ch].
1869 * Added silc_buffer_set function that is used to set data
1870 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
1871 Affected file lib/silcutil/silcbuffer.h.
1873 * Changed various routines in the core library to use the new
1874 silc_buffer_set instead of allocating new buffer only for
1877 * Added 64-bit value formatting and unformatting support to the
1878 silc_buffer_[un]format routines. Affected file is
1879 lib/silcutil/silcbuffmt.[ch].
1881 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
1882 to includes/bitmove.h.
1884 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1886 * Fixed channel user mode saving in client library. Affected
1887 file lib/silcclient/command[_reply].c.
1889 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1891 * Defined the file transfer to the SILC Protocol. Added
1892 new packet type SILC_PACKET_FTP and defined File Transfer
1893 Payload. The mandatory file transfer protocol is SFTP
1894 (SSH File Transfer Protocol). Affected file in addition
1895 of the internet draft is lib/silccore/silcpacket.h.
1897 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
1898 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
1899 is used as part of backup router protocol when the primary
1900 router of the cell is back online and wishes to resume
1901 the position as primary router.
1903 * Redefined the MAC generation keys in the protocol. The
1904 same key is not used anymore in both direction. Both
1905 direction will now use different keys for sending and
1906 receiving. This fixes a potential security flaw. This
1907 change causes incompatibilities in the protocol.
1909 * Redefined also the MAC computation from the packet.
1910 An packet sequence number is now added to the MAC
1911 computation. This prevents possible replay attacks against
1912 the protocol. This change too causes incompatibilities
1915 Added `sequence' field to the SilcPacketContext to hold
1916 the current sequence number for the packet.
1918 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1920 * Added `created' field to the SilcIDListData in the file
1921 silcd/idlist.h to indicate the time when the entry was
1924 * Added `created' field to the SilcChannelEntry too. Affected
1925 file silcd/idlist.h.
1927 * Added `creation_time' aguments to all the announcement functions
1928 in the server. If it is provided then only the entries that
1929 was created after the provided time frame are actually
1930 announced. Affected file silcd/server.[ch].
1932 * The protocol says that the Channel ID's IP address must be
1933 based on the router's IP address. Added check for this in
1934 the silc_server_new_channel when processing incoming New Channel
1935 Payload. Affected file silcd/packet_receive.c.
1937 * Print out the correct version with --version in SILC client.
1938 Affected file irssi/src/silc/core/silc-core.c.
1940 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1942 * Fixed WHOWAS command to check for completnes of the client
1943 entry always, not just when the command is coming from client.
1944 Affected file silcd/command.c.
1946 * Added new function silc_server_packet_queue_purge to purge the
1947 outgoing data queue to the network. After the function returns
1948 it is guaranteed that the outgoing packet queue is empty.
1949 Affected file silcd/packet_send.[ch].
1951 * Purge the outgoing packet queue in the rekey protocol's final
1952 callback to assure that all rekey packets go to the network
1953 before quitting the protocol. Affected file silcd/server.c.
1955 * Added silc_client_packet_queue_parse as similar function as
1956 in server to the client library. The affected file is
1957 lib/silcclient/client.c.
1959 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1961 * Splitted silcd/server.c and created silcd/server_util.[ch]
1962 for utility functions.
1964 * Added new socket flag SILC_SF_DISABLED to indicate that the
1965 connection is open but nothing can be sent to or received from
1966 the connection. Affected file lib/silcutil/silsockconn.[ch].
1967 The checking for disabled socket is checked in the low level
1968 silc_socket_write and silc_socket_read functions.
1970 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1972 * Allow only nicknames and channel names that fits into the
1973 7-bit unsigned char ASCII set. Affected file silcd/command.c.
1975 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1977 * When processing JOIN command reply in server check that if
1978 the channel exists in our global list we'll move it the local
1979 list. Affected file silcd/command_reply.c.
1981 * Fixed the check whether client is joined on the channel already
1982 in JOIN command. Affected file lib/silcclient/command.c.
1984 * Fixed the JOIN command reply to check whether the channel
1985 already exists. Affected file lib/silcclient/command_reply.c.
1987 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1989 * Added silc_ske_status_string to map the SKE error numbers
1990 to readable strings. The affected files are
1991 lib/silcske/silcske[_status].[ch].
1993 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1995 * Do not show the private channels on the WHOIS channel list
1996 as it is not allowed by the protocol. The affected file is
1999 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2001 * Assure that the packet length digged from the actual packet
2002 is something sensible in the silc_packet_decrypt_rest_special
2003 in lib/silccrypt/silcpacket.c.
2005 * Free and NULL the allocated pointer in silc_hmac_alloc if
2006 the HMAC allocation fails. The affected file is
2007 lib/silccrypt/silchmac.c.
2009 * Print the selected security properties to the log files in
2010 the server. Affected file silcd/protocol.c.
2012 * Add SKE's reference counter even if calling the completion
2013 callback manually. Otherwise it goes negative, although it
2014 does not cause any problems. The affected file is
2015 lib/silcske/silcske.c.
2017 * Remove the client entry with short timeout after giving the
2018 KILL command. Affected file lib/silcclient/command.c.
2020 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2021 case all found clients are already disconnected (WHOWAS would
2022 found them) in the server. Affected file silcd/command.c.
2024 * Update the last_receive (time of last data received) to be
2025 updated only when received private or channel message so that
2026 the idle time showed in WHOIS makes more sense.
2028 * Added boolean field `valid' in to the SilcClientEntry in the
2029 client library to indicate whether the entry is valid or not.
2030 This fixes the nickname change bug on channel when changing
2031 the nickname to be same than the old (like nick to Nick) the
2032 nickname formatter doesn't set the new nick anymore to Nick@host.
2033 Affected file lib/silcclient/idlist.[ch].
2035 * Now actually fixed the nickname changing on disconnection.
2036 Added new function silc_change_nick to the Irssi SILC Client.
2037 Affected file irssi/src/silc/core/client_ops.c,
2038 irssi/src/silc/core/silc-nicklist.[ch].
2040 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2042 * Check that the public key exists in the GETKEY command before
2043 trying to encode it. Affected file silcd/command.c.
2045 * Print some notifications on received public keys with GETKEY
2046 command in the Irssi SILC Client. Affected files are
2047 irssi/src/fe-common/silc/module-formats.[ch],
2048 irssi/src/silc/core/client_ops.c.
2050 * Use IDENTIFY command to resolve the server information in the
2051 GETKEY command instead of INFO command. Affected file
2052 lib/silcclient/command.c.
2054 * All command reply functions in the client library now calls
2055 the pending command reply callbacks even if an error has
2056 occurred. The server has done this a long time and now it was
2057 time to move the client library to this as well. Now all
2058 errors can be delivered back to the pending command reply
2059 callbacks if necessary. Affected files are
2060 lib/silcclient/command[_reply].[ch].
2062 * Change the nickname on disconnection back to the username
2063 because in reconnect the server will enforce it to it anyway.
2064 Affected file irssi/src/silc/core/silc-servers.c.
2066 * Fixed a config file parsing bug in the Irssi SILC client.
2067 Affected file irssi/src/silc/core/clientconfig.c.
2069 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2071 * When printing the channel mode on JOIN, verify that the
2072 channel key and channel's HMAC are valid. Affected file
2073 irssi/src/silc/core/client_ops.c.
2075 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2077 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2078 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2079 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2081 * Removed channel key rekey task deleting from the function
2082 silc_server_save_channel_key. Affected file silcd/server.c.
2083 Added explicit timeout task context instead that is used to
2084 delete the task if we are registering a new task before the
2085 new task has elapsed.
2087 * When channel key rekey occurs the client library now saves
2088 the old channel key for a short period of time (10 seconds) and
2089 is able to use it in case some is still sending channel
2090 messages encrypted with the old key after the rekey. Affected
2091 file lib/silcclient/[idlist.h|client_channel.c].
2093 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2095 * Added check to the silc_server_new_id_real to not accept
2096 new ID if it is the sender's own ID. Affected file is
2097 silcd/packet_receive.c.
2099 * Assure that we do not announce ourself or the one we've
2100 sending our announcements when we're router and are announcing
2101 servers to our primary router. Affected file silcd/server.c.
2103 * Fixed silc_server_command_identify_check_client to assemble
2104 correct WHOIS packet. It send corrupted WHOIS packet and
2105 caused problem with router to router connections. Affected
2106 file silcd/command.c.
2108 Fixed also silc_server_command_whois_check the same way
2109 as for the IDENTIFY command.
2111 * Added new SilcIDListStatus to the server in the SilcIDListData
2112 structure. The status now includes the current status of
2113 the entry (like registered, resolved etc.). Affected file
2114 silcd/idlist.[ch]. Defined a bunch of different status types
2115 as well. This replaced the old boolean registered field as well.
2117 Added resolve_cmd_ident field to the SilcClientEntry structure
2118 too so that if the entry is for example being resolved so
2119 another command may attach to the same pending command reply
2120 without requiring to resolve the same entry again. This concept
2121 should optimize the WHOIS and the IDENTIFY resolving under
2122 heavy load by taking away unnecessary resolving for entries
2123 that are being resolved already.
2125 Added support for adding multiple pending commands for one
2126 command idenfier. Affected file silcd/command[_reply].[ch].
2128 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2129 before deleting the data. Otherwise the hash table will have
2130 freed data in comparison functions. Affected file is
2131 silcd/command_reply.c.
2133 * Fixed silc_idlist_replace_client_id to add the new entry to
2134 the cache with NULL nickname. Otherwise there will be invalid
2135 memory as the nickname after the nickname is freed. Affected
2136 file silcd/packet_receive.c.
2138 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2139 saved into wrong slots because the previous number of entries
2140 was not taken into account. Affected file silcd/idlist.c.
2141 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2143 * If we are router and we receive JOIN notify to a channel that
2144 does not have any users then notified client is marked as the
2145 channel founder, as it is it. The affected file is
2146 silcd/packet_receive.c
2148 * Added to the extended hash table API's table_del_*ext functions
2149 the destructor as argument too, so that the caller can decide
2150 which destructor to use or whether to use destructor at all.
2151 Affected file lib/silcutil/silchashtable.[ch].
2153 * Fixed ID Cache purging. It actually deleted the entries from
2154 the hash table after the data was freed. The hash table ended
2155 up comparing freed memory. The affected file is
2156 lib/silccore/silcidcache.c.
2158 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2160 * Fixed Irssi SILC client's KILL command's HELP syntax.
2162 * The USERS command now resolves the detailed user information
2163 if the userinfo field is missing. Affected file is
2164 lib/silcclient/command_reply.c.
2166 * Do not print error in silc_file_read if the read file does
2167 not exist. Just silently return NULL. Affected file is
2168 lib/silcutil/silcutil.c.
2170 * Fixed the silc_log_output to not wine about NULL filename
2171 and to not create some bogus " " filename. Affected file is
2172 lib/silcutil/silclog.c.
2174 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2176 * Fixed various printing bugs on the user interface in the
2177 Irssi SILC Client. Minor changes that were forgotten from
2180 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2182 * Fixed the configure.in.pre and the compilation and distribution
2183 environment to support the new autoconf 2.52. That version is
2184 now required to compile the CVS trunk.
2186 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2188 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2189 to generally parse user@fqdn format strings. Affected file
2190 lib/silcutil/silcutil.c.
2192 * Added nickname_format and nickname_force_format fields to the
2193 SilcClientParams structure. The first one defines the format
2194 for the nicknames that the library will enforce if the receives
2195 multiple same nicknames. The second one is boolean value and
2196 can be used to force the library to always enforce the format
2197 to the nicknames regardles whether there are multiple nicknames
2198 or not. This configurable formatting was employed to flexibly
2199 support accessing multiple nicknames from the user interface.
2200 The userinterface can now set the nicknames to what ever format
2201 they prefer. Affected file lib/silcclient/silcapi.h.
2203 Added function silc_client_nickname_format to the file
2204 lib/silcclient/idlist.c. It performs the nickname formatting.
2206 Added new field `hostname´ to the SilcClientEntry context.
2207 It holds the hostname of the client. Affected file is
2208 lib/silcclient/idlist.h.
2210 * Irssi SILC Client sets the nicknames in nick@hostn format.
2211 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2212 irssi/src/silc/core/silc-core.c.
2214 The WHOIS printing now also shows both the real nickname and
2215 the formatted nickname so that user knows how to access the
2216 user if there are multiple same nicknames cached. Affected
2217 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2218 printing formatting too to take the hostname now as a separate
2219 argument. The Affected file is
2220 irssi/src/fe-common/silc/modules-formats.[ch].
2222 * Changed the silc_client_get_clients_local to accept the formatted
2223 nickname as argument. It accepts the real nickname too but the
2224 formatted nickname can be used to find the true entry from
2225 multiple entries. Affected file lib/silcclient/silcapi.h and
2226 lib/silcclient/idlist.c.
2228 * Added nickname_format_parse field to the SilcClientParams.
2229 It is a callback function provided by the application to parse
2230 the nickname out of the formatted nickname string. The library
2231 calls it to get the nickname from the formatted string. Since
2232 the application generally knows better the format of the nickname
2233 string it parses it instead of the library, even though library
2234 encodes the formatted string. If the callback function is not
2235 provided then the library will use the string as is. The
2236 affected file is lib/silcclient/silcapi.h.
2238 * All the nickname strings passed to the client library in
2239 commands are now expected to be formatted nickname strings.
2240 If the command does not support the formatted nickname string
2241 it will assume that the sent string is the actual nickname.
2242 Affected file lib/silcclient/command.c.
2244 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2246 * Added public key authentication support to OPER and SILCOPER
2247 commands in the client library. Affected file is
2248 lib/silcclient/command.c.
2250 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2252 * Changed the get_auth_methdod client operation to be asynchronous.
2253 It can be async if the application resolves the authentication
2254 method from the server during the negotiation. Added new
2255 SilcGetAuthMeth completion callback that the application will
2256 call after resolving the authentication method.
2258 Added function silc_client_request_authentication_method that
2259 the application can use to resolve the authentication method
2260 from the server. Added also SilcConnectionAuthRequest callback
2261 that the library will call after the server has replied. The
2262 application can call this function if it does not know the
2263 current authentication method.
2265 Affected files are lib/silcclient/client.c and
2266 lib/silcclient/silcapi.h.
2268 * The Irssi SILC client now automatically resolves the authentication
2269 method incase any configuration information is not present (and
2270 currently there never is). The affected file is
2271 irssi/src/silc/core/client_ops.c.
2273 * Fixed public key authentication from the client library.
2274 Affected file lib/silcclient/protocol.c. Changed also the
2275 protocol specification about the public key authentication in
2276 the connection authentication protocol. The actual data to be
2277 signed is now computed with a hash function before signing.
2279 * Fixed the public key authentication from the server as well.
2280 Affected file silcd/protocol.c.
2282 * Removed the mlock()'s from the memory allocation routines.
2283 Affected file lib/silcutil/silcmemory.c. The ./configure does
2284 not check anymore for the mlock(). Affected file is
2287 * Fixed USERS command in server to allow the execution of the
2288 command for private and secret channels if the client sending
2289 the command is on the channel. Affected file silcd/command.c.
2291 * Fixed silc_client_get_clients_local to return the clients
2292 count correctly. It could return wrong value. Affected file
2293 lib/silcclient/idlist.c.
2295 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2297 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2298 types. The assembler optimizations seemed not to like 64-bit
2299 data types. The assmebler optimizations thus are now enabled
2300 also for BSD systems as opposed to only enable them for Linux.
2302 * Do not check for threads at all on BSD systems. Affected
2303 file configure.in.pre.
2305 * Removed -n and -h options from the Irssi SILC Client since
2306 they are not used in silc.
2308 * Fixed the prime generation to assure that the first digit
2309 of the generated random number is not zero since our conversion
2310 routines does not like number strings that starts with zero
2311 digit. If zero digit is seen the random number is regenerated.
2312 This caused some corrupted RSA keys when the zero first digit
2313 was met. Affected file lib/silcmath/silcprimegen.c.
2315 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2317 * Fixed WIN32 configuration in the ./configure script.
2318 Fixed to include xti.h on environments that has it.
2319 Patches by Carsten Ilchmann and andrew.
2321 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2323 * Changed the silc_id_create_client_id to be collision
2324 resistant. It is now assured that there cannot be created
2325 two same client ID's. I suspect that some weird bugs in
2326 the server were actually caused by duplicate Client IDs.
2327 Affected file silcd/serverid.[ch]. A router receiving
2328 new ID now also assures and informs the sending server
2329 if the ID caused collision.
2331 * Changed the silc_id_create_channel_id to also assure that
2332 there are no collisions.
2334 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2336 * Statement about ignoring the Mutual Authentication flag when
2337 performing rekey with PFS was a bit misleading. It is ignored
2338 if it was set in the initial negotiation, it cannot be even
2339 set in the rekey. Fixed in the ke-auth draft. Started the
2340 new versions of the protocol drafts in the doc/.
2342 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2344 * Fixed a bug in silc_client_command_identify_save when saving
2345 new channel information. The channel name was no duplicated
2346 and caused crash on exit. Affected file is
2347 lib/silcclient/command_reply.c.
2349 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2351 * Fixed the getkey command handling in the server. Send just
2352 empty OK reply to the sender if the key could not be fetched
2353 (but everything else was ok, like the key just was not available).
2354 Changed the public key parameter to optional in the protocol
2355 specs so that empty OK reply can be sent. Affected file
2358 Added a message to Irssi SILC client to tell to user if the
2359 server did not return a public key.
2361 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2363 * Fixed a channel key regeneration bug. It registered new
2364 timeout tasks exponentially until all system resources were
2365 used. Affected file silcd/server.c.
2367 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2369 * Added the SILC Document generator to the scripts/silcdoc.
2370 It can be used to generate the Toolkit Reference Manual out
2371 of the source tree. Internally it will also use the RoboDoc
2372 generator now imported in util/robodoc.
2374 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2376 * Added couple of return's in rekey protocol if error orccurred
2377 during the protocol. The execution must be terminated.
2378 Affected file silcd/protocol.c. Also, terminate the protocol
2379 always with timeout.
2381 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2383 * The client's Client ID was created initally from the wrong
2384 nickname (it could have been in format nick@host) in the
2385 silc_server_new_client. Affected file silcd/packet_receive.c
2387 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2389 * Added some SILC_LOG_ERROR's to various error conditions
2390 if client could not be added to ID cache. Affected files
2391 silcd/packet_receive.c and silcd/server.c.
2393 * When client's sock->user_data is freed, NULL also the
2394 client->router and client->connection pointers. Added check
2395 for these pointers being NULL to various places around the
2396 code. Affected file silcd/server.c.
2398 * Added client->data.registered == TRUE checks to various
2399 places around the code to assure that unregistered client's
2400 are not handled when it is not allowed. Affected file
2403 * Added `bool registered' fields to all
2404 silc_idlist_[server|client]_get_* routines to indicate whether
2405 the fetched client needs to be registered or not. Affected
2406 file silcd/idlist.[ch].
2408 * Add your own entry as registered to the ID cache in the
2409 server. Affected file server.c.
2411 * Fixed a bug in silc_server_new_server. The SilcServer was
2412 set as the new server's context instead of SilcServerEntry.
2413 This naturally caused some weird bugs.
2415 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2417 * Do not delete the channel rekey task when adding it
2418 for in silc_server_create_channel_key.
2420 * Changed the silc_server_create_channel_key to return
2421 TRUE or FALSE to indicate the success of the channel key
2424 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2426 * Fixed MSVC++ project files and added missing files to
2427 Makefiles under win32/.
2429 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2431 * Do not add TCP_NODELAY flag if the operating system
2432 does not have it defined. Affected files are
2433 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2435 * Fixed buffer overflow from Irssi SILC Client. Affected
2436 file irssi/src/fe-common/core/themes.c.
2438 * Fixed double free in client library in the file
2439 lib/silcclient/client.c when disconnecting from server.
2441 * Applied double free patch from cras to Irssi SILC client.
2442 Affected files irssi/src/core/[modules/expandos].c
2444 * Fixed the disconnection handling to Irssi SILC Client.
2445 The application must call silc_client_close_connection
2446 in ops->connect client operation in case of failure of
2447 the connection. Affected file is
2448 irssi/src/silc/core/client_ops.c.
2450 * Do not set sock->protocol to NULL in the function
2451 silc_client_close_connection after executing the protocol's
2452 final callback since the sock might not be valid anymore.
2453 Affected file lib/silcclient/client.c.
2455 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2457 * Do not enable SILC_THREADS if the linking with libpthread
2458 did not happen. Affected file configure.in.pre.
2460 * Added notion to protocol specification that server must
2461 verify the sent authentication payload with CMODE when
2462 setting the channel founder key. Implemented it to the
2463 server. Affected file silcd/command.c.
2465 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2467 * Added _EXTRA_DIST SILC distribution variable to the
2468 distributions file. It is used to conditionally add extra
2469 files or directories to the specific distribution. Affected
2470 files ./prepare, Makefile.am.pre and distributions.
2472 Removed the `_' from the start of the distribution names.
2475 * Added README.WIN32 for instructions to compile the Toolkit
2478 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2480 * Fixed a double free in disconnection in the server. Affected
2481 file is silcd/server.c.
2483 * Fixed the lib/silcske/groups.c to work now also with GMP
2484 MP library. The string conversion did not work when using
2485 specific base and the base is indicated in the string as well.
2487 * Created win32/ directory which now includes MSVC++ specific
2488 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2489 It will appear only in the toolkit distribution
2491 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2493 * Changed the key material distribution function in case when
2494 the hash output is too short. The data is now concatenated
2495 a bit differently than it used to. Made the change to the
2496 SKE protocol specification.
2498 * Added better GMP detection to configure.in.pre. A patch
2501 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2503 * Fixed a minor bug in SKE that might cause some problem on
2504 some platforms. Affected file lib/silcske/silcske.c.
2506 * Added the cookie checking for initiator in the SKE. It checks
2507 that the responder returns the sent cookie unmodified. The
2508 affected file is lib/silcske/silcske.c. Added new SKE
2509 error type INVALID_COOKIE that can be sent during the
2510 negotiation. Fixed some memory leaks as well.
2512 * Added the "invalid cookie" error message to Irssi SILC client's
2515 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2517 * Added `task_max' field to the SilcClientParams to indicate
2518 the maximum tasks the scheduler can handle. If set to zero,
2519 default values are used. Affected file lib/silcclient/silcapi.h.
2521 * Fixed memory leaks in silc_client_close_connection. Affected
2522 file lib/silcclient/client.c.
2524 * Added silc_client_del_client_entry to client library to free
2525 all memory of given client entry. Affected file is
2526 lib/silcclient/idlist.[ch].
2528 * Added new functions silc_client_del_channel and
2529 silc_client_del_server to delete channel and server entries.
2530 Affected file lib/silcclient/[silcapi.h/idlist.c].
2532 * Removed silc_client_del_client_by_id from silcapi.h.
2534 * Fixed the INFO command to return the server's own info
2535 correctly when querying by Server ID. Affected file is
2538 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2540 * Removed the non-blocking settings in WIN32 code in the
2541 silc_sock_[read/write] and added SleepEx instead. Affected
2542 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2543 of input data is now checked with FIONREAD and ioctlsocket.
2545 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2547 * Call silc_schedule_task_del_by_context in the
2548 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2549 Affected file lib/silccore/silcprotocol.c.
2551 * Call silc_protocol_cancel for active protocols in the
2552 silc_server_close_connection if the funtion
2553 silc_server_free_sock_user_data has not been called.
2554 Affected file silcd/server.c.
2556 * Generic tasks cannot be deleted using the del_by_fd
2557 task deleting function since generic tasks does not match
2558 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2560 * Added a notion to SILCOPER help file that the SILCOPER works
2561 only on router server, not on normal server.
2563 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2565 * Added for WIN32 support for the new scheduler as well.
2566 Affected file lib/silcutil/win32/silcwin32schedule.c.
2568 * Fixed the SHA1 implementation to work on various platforms.
2570 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2572 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2573 API. It is part of the scheduler now. Everything else is
2574 as previously but some functions has changed their names.
2575 Checkout the lib/silcutil/silcschedule.h for the interface.
2576 Updated all applications to use the new interface. Affected
2577 files are lib/silcutil/silcschedule.[ch].
2579 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2581 * Found a bug in the SKE implementation. The HASH value,
2582 specified by the protocol, was not computed correctly. The
2583 public key of the responder was not added to the computation
2584 even though it is mandatory. Affected file lib/silcske/silcske.c.
2585 This unfortunately causes incompatibilities with older
2586 clients and servers.
2588 * Added WIN32 specific network init and uninit functions:
2589 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2590 the Winsock2. Affected file lib/silcutil/silcnet.h and
2591 lib/silcutil/win32/silcwin32net.c.
2593 * Set the socket always to nonblocking mode on WIN32 after
2594 reading data or writing data. Affected file is
2595 lib/silcutil/win32/silcwin32sockconn.c.
2597 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2599 * Fixed various compilation problems under WIN32. Affected
2600 files lib/silcutil/win32/silcwin32thread.c and
2601 lib/silcutil/win32/silcwin32schedule.c.
2603 * Removed all _internal.h #includes from public header
2604 files. Internal headers must never be included from
2607 Removed also the lib/silcske/payload_internal.h file.
2609 * All include files that may be needed (public and some others
2610 included by the public headers) by application developers are
2611 now copied to the ./includes directory. It does not copy any
2612 internal headers. Affected file Makefile.defines.pre and all
2613 Makefile.am's under lib/ and subdirs.
2615 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2617 * Do not change the ~/.silc directory's permissions automatically.
2618 Affected file irssi/src/silc/core/clientutil.c.
2620 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2622 * Do not cancel the protocol in silc_server_close_connection
2623 it might cause recursion. Now cancelled in the function
2624 silc_server_free_sock_user_data. Affected file silcd/server.c.
2626 * Fixed the silc_server_remove_clients_by_server to regenerate
2627 the channel keys correctly finally. Added also new function
2628 silc_server_remove_clients_channels to actually do it.
2629 Affected file silcd/server.c.
2631 * Fixed the silc_server_new_channel to not crash by giving
2632 wrong router to the new channel. Affected file is
2633 silcd/packet_receive.c.
2635 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2637 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
2638 which is given as argument to the silc_client_alloc now.
2639 It can be used to configure the client and set various parameters
2640 that affect the function of the client.
2642 * The USERS command in server did not check whether the channel
2643 is private or secret. Affected file silcd/command.c.
2645 * Added new argument to the USERS command in protocol specification.
2646 The USERS command now can take the channel name as argument
2647 as well. Added support for this in client and server and
2648 updated the protocol specs.
2650 * Completed the GETKEY command in client. It can be now used
2651 to fetch also servers public key not only some clients.
2652 Affected files lib/silcclient/command[_reply].c.
2654 * Added silc_client_get_server to return server entry by the
2655 server name. Affected files lib/silcclient/silcapi.h and
2658 * Redefined the IDENTIFY command in protocol specification to be
2659 more generic. It now can be used to query information about
2660 any entity in the SILC Network, including clients, servers and
2661 channels. The query may be based either the entity's name
2662 or the ID. Added support for this in both client and server.
2664 Affected files silcd/command.c and lib/silcclient/command.c
2665 and command_reply.c.
2667 * Optimized the WHOIS and WHOWAS commands in the server. Removed
2668 the _from_client and _from_server functions. Affected file
2671 * Added silc_client_get_channel_by_id_resolve to the file
2672 lib/silcclient/silcapi.h to resolve channel information by
2673 its ID. Added also silc_client_get_channel_by_id that
2674 does not resolve it from the server.
2676 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2678 * Added SilcServerEntry context into the client library
2679 to represent one server. The INFO command now allocates
2680 these to save the resolved server info. For now on the
2681 client library will also keep information about servers,
2682 connected and resolved with INFO.
2684 The INFO command now allocates the SilcServerEntry context
2685 and saves the server info there. The COMMAND_REPLY in
2686 the INFO now returns the parameters to application in
2687 same order as defined in the protocol specification.
2689 The entries are cached in the client->server_cache.
2691 * The INFO command is now issued after received the Client ID
2692 from the server. Affected file lib/silcclient/client.c.
2694 * The CMODE_CHANGE notify may now return also an SilcServerEntry
2695 to the application as the mode changer might be server.
2696 It is guaranteed that NULL is not returned anymore to the
2697 application. Affected file lib/silcclient/client_notify.c.
2699 The ID Type is now also passed to the application so that
2700 it can check whether the returned entry is SilcClientEntry
2703 Added new function silc_client_get_server_by_id to return
2704 the server entry by ID. Affected files are the
2705 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
2707 * Do not create the channel in the Irssi SILC Client when issuing
2708 the JOIN command but when received the sucessful JOIN command
2709 reply. Otherwise the channel might get created even though we
2710 could not join it. The Affected file is
2711 irssi/src/silc/core/[silc-channels.c/client_ops.c].
2713 * Fixed a channel joining bug in router. The router must also
2714 check the channel modes, invite and ban lists etc. when serving
2715 the JOIN command sent by normal server. Affected file is
2716 silcd/command.c. The router now resolves the client's
2717 information from the server who sent the JOIN command if it
2718 does not know it, and processes the JOIN command only after
2721 * Changed the SilcCommandCb to take new argument; void *context2.
2722 Affected file lib/silccore/silccommand.h
2724 The second argument in the command callbacks in the server now
2725 includes the SilcServerCommandReplyContext if the command was
2726 called as pending command callback from the command reply.
2727 Otherwise it is NULL. When called as pending the status of the
2728 command reply will be checked and if it was erronous the
2729 error will be sent to the original sender of the command.
2730 This way the client always receives the error messages even
2731 though the server was actually the one who received the error
2732 when it resent the command to router, for example. Affected
2733 files silcd/command[_reply].[ch].
2735 * Fixed sending WHOWAS command's error message to client if
2736 the requested client could not be found. It was missing.
2739 * Changed the CMODE and CUMODE commands reply arguments in the
2740 protocol specification. The Channel ID is now sent in both
2741 of the commands to identify the channel. Implemented this
2742 new feature to the client and server. Affected files
2743 lib/silcclient/command_reply.c and silcd/command.c.
2745 * Made better checks for invite and ban lists in the JOIN
2746 command in server. Affected file silcd/command.c.
2748 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2750 * The server now performs the incoming host IP/DNS lookup
2751 using the silc_socket_host_lookup and thus does not block
2752 the server anymore. Affected file silcd/server.c.
2754 * Completed the multi-thread support for SILC Scheduler in
2755 the lib/silcutil/silcschedule.c.
2757 * Fixed the configure.in.pre to detect the pthread correctly
2760 * Fixed a deadlock in silc_task_queue_wakeup in the file
2761 lib/silcutil/silctask.c.
2763 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2765 * Added new function silc_schedule_wakeup that is used in
2766 multi-threaded environment to wakeup the main thread's
2767 schduler. It needs to be used when a thread adds a new task
2768 or removes a task from task queues. After waking up, the
2769 scheduler will detect the task queue changes. If threads
2770 support is not compiled in this function has no effect.
2771 Implemented the wakeup mechanism to both Unix and WIN32
2772 systems. Affected files are lib/silcutil/silcschedule.[ch],
2773 lib/silcutil/unix/silcunixschedule.c and the
2774 lib/silcutil/win32/silcwin32schedule.c.
2776 * Added new function silc_task_queue_wakeup to wakeup the
2777 scheduler by the specified task queue. Affected file
2778 lib/silcutil/silctask.[ch].
2780 * The silc_socket_host_lookup_start now wakes up the scheduler
2781 after adding the timeout task. Affected file is
2782 lib/silcutil/silcsockconn.c.
2784 * The silc_socket_host_lookup is synchronous now if the threads
2785 support is not compiled in. However, the callback is still
2786 called asyncronously through the scheduler, anyway. Affected
2787 file lib/silcutil/silcsockconn.c.
2789 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2791 * Added new function silc_socket_host_lookup to perform
2792 asynchronous IP and FQDN lookups for the socket connection.
2793 Affected files lib/silcutil/silcsockconn.[ch].
2795 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2797 * Added SILC_MUTEX_DEFINE to define the mutex on environments
2798 that may or may not compile the mutex support in.
2800 Changed the silc_mutex_alloc interface. It allocates the
2801 mutex now to the sent pointer and returns TRUE or FALSE.
2803 Affected file lib/silcutil/silcmutex.h.
2805 * Wrote the SILC Task Queue interface to support multi-threads.
2806 Affected file lib/silcutil/silctask.[ch].
2808 * Wrote the SILC Scheduler to support multi-threads. Affected
2809 file lib/silcutil/silcschedule.c.
2811 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2813 * Implemented the SILC Mutex API and SILC Thread API for WIN32
2814 in lib/silcutil/win32/.
2816 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2818 * Defined SILC Mutex API and SILC Thread API and implemented
2819 them for Unix. Affected files are
2820 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
2821 lib/silcutil/unix/silcunixmutex.c and
2822 lib/silcutil/unix/silcunixthread.c.
2824 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2826 * Fixed the silc_server_remove_clients_by_server's channel
2827 key re-generation. The hash table handling was incorrect
2828 and would not work with many channels. Affected file is
2831 * Fixed some memory leaks around the server code.
2833 * Rewrote the silc_server_get_users_on_channel to support IPv6
2834 based Client ID's. Affected file silcd/server.c.
2836 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
2837 specification. However, a separate document must be written
2838 to define the detailed signing procedure and the payload
2839 associated with the flag. Defined the flag to the
2840 lib/silccore/silcchannel.h as well.
2842 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2844 * Changed the dynamic tables to static size tables in the
2845 lib/silccrypt/silchmac.c.
2847 * Removed GCC dependencies from the code. A patch by cras.
2849 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2851 * Do not show the error "Error receiving packet bla bla"
2852 in server if it really was not an error (-2 means that reading
2853 is pending). Affected file silcd/server.c.
2855 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2857 * Fixed a possible crash in silc_server_remove_clients_by_server
2858 in silcd/server.c. Fixed there also some memory leaks.
2860 * Fixed the silc_idlist_replace_client_id. It could replace
2861 wrong key in the hash table. Affected file silcd/idlist.c.
2863 * Do not check whether there are global users on the channel
2864 if the channel->global_users is FALSE. Affected functions
2865 silc_server_remove_from_one_channel and
2866 silc_server_remove_from_channels in silcd/server.c. Also,
2867 do not check if the removed client is local as we can be
2868 sure that global client was not removed from the channel
2869 and checking for global users is not needed.
2871 * The silc_server_remove_clients_by_server now re-generates
2872 the channel keys correctly for those channels that had
2873 clients removed from them. Affected file silcd/server.c.
2875 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2877 * Found the reason of random crashes in the server. We weren't
2878 ignoring the SIGPIPE signal (which can be sent in write())
2879 and it crashed the server. Affected file silcd/silcd.c.
2881 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2883 * Assure that sock->user_data is not NULL in the function
2884 silc_server_packet_send in silcd/packet_send.c.
2886 * Disconnect the remote connection if it could not be added
2887 to any ID lists in the server. The affected file is
2890 * Check in silc_server_packet_send[_real/dest] that the
2891 socket is not disconnecting and ignore the data if it is.
2892 Affected file silcd/packet_send.c.
2894 * Define inline to __inline on native WIN32 compilation.
2895 Affected file includes/silcwin32.h.
2897 * Added some explicit type casts for inline code since MSVC
2898 require them. Affected files lib/silcutil/silcbuffer.h,
2899 lib/trq/silcdlist.h and lib/trq/silclist.h.
2901 * Print warning in log files from now on if the packet
2902 decryption fails. Affected file silcd/server.c.
2904 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2906 * Changed the `say' client operation's interface to accept
2907 new `type' argument to indicate the type of the message sent
2908 by the library. The application may filter the library's
2909 messages according the type. The affected file is the
2910 lib/silcclient/silcapi.h.
2912 * Added two new functions to lib/silcclient/silcapi.h:
2913 silc_client_del_client and silc_client_del_client_by_id.
2914 Affected file lib/silcclient/idlist.c.
2916 * Moved the clientincludes.h from includes/ to silc/ and
2917 serverincludes.h from includes/ to silcd/.
2919 * The modes for the CMODE and CUMODE are now passed as
2920 uint32 for application with COMMAND_REPLY. The affected
2921 file is lib/silcclient/command_reply.c.
2923 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2925 * /WHOIS without arguments shows client's own information.
2926 Affected file lib/silcclient/command.c.
2928 * Changed PING to not accept any arguments. The specs
2929 says that client can ping only the connected server so
2930 requiring an argument is not needed. Affected file is
2931 lib/silcclient/command.c.
2933 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2935 * Fixed a fatal bug in private message sending and reception
2936 encryption and decryption when using private message keys.
2937 The implementation was incorrect and did not follow the
2938 specification. It causd that some of the message were
2939 lost since it did not use the sending and receiving keys
2940 as the protocol suggests. This has been fixed and will cause
2941 incompatibilities with older clients when sending private
2942 message encrypted with private message keys. Affected files
2943 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
2944 and various other in Irssi SILC Client.
2946 Added `responder' boolean argument to the functions
2947 silc_client_add_private_message_key[_ske] to indicate when
2948 the key is added as responder or initiator of the key
2951 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2953 * Removed the silc_ske_check_version function and created
2954 a SilcSKECheckVersion callback. Added also a function
2955 silc_ske_set_callbacks that is now used to set all SKE
2956 callbacks. The callback functions are not given to
2957 the SKE functions anymore, but this function is used to
2960 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
2962 * Added `silc_version' argument to the silc_client_alloc
2963 to define the version of the application for the library.
2964 The library will use the version string to compare it
2965 against the remote host's (usually a server) version
2966 string. Affected file lib/silcclient/silcapi.h
2968 * Added the KE protocol context to Key Agreement context
2969 in client library so that we can abort the SKE if it
2970 is in process when we get timeout. Affected file is
2971 lib/silcclient/client_keyagr.c.
2973 * Do not resolve the client ID forever if it returns in the
2974 first time that such client does not exist. This was done
2975 for example with private message. Affected file is
2976 lib/silcclient/client_prvmsg.c.
2978 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2980 * Do not add regex.h for WIN32. The affected file
2981 includes/silcincludes.h.
2983 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
2984 not work yet 100%. It generates the DLL's automatically
2985 when compiling with --with-win32 under cygwin.
2987 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2989 * lib/contrib/regex.c is not compiled on WIN32.
2991 * Added silc_net_get_socket_opt function to the
2992 lib/silcutil/silcnet.h.
2994 * Added includes/silcwin32.h for WIN32 specific includes
2997 * Do not use ptime structure or any of the posix process
2998 functions on WIN32 in lib/silccrypt/silrng.c.
3000 * Added silc_gettimeofday to provide generic function
3001 for struct timeval on all platforms. Added the function
3002 to lib/silcutil/silcutil.h.
3004 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3006 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3007 library as they clearly belong there. As a plus side we
3008 can make the actual socket connection routines platform
3011 Added also new generic function silc_socket_read and
3012 silc_socket_write (that used to be silc_packet_[read/write].
3013 The implementation of these are platform specific.
3015 * Added WIN32 specific routines of silc_socket_[read/write]
3016 to lib/silcutil/win32/silcwin32sockconn.c.
3018 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3020 * Added preliminary support for native WIN32 compilation under
3021 cygwin (using the -mno-cygwin option for GCC) to the
3022 ./configure.in.pre. The --with-win32 now prepares the
3023 compilation for native WIN32.
3025 * Rewrote the SILC Scheduler interface in the file
3026 lib/silcutil/silcschedule.h. The scheduler is now context
3027 based and does not have anymore any global static scheduler.
3028 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3029 and created lib/silcutil/win32 directory for WIN32 based
3032 * Added Unix specific network routines to the
3033 lib/silcutil/unix/silcunixnet.c and the old
3034 lib/silcutil/silcnet.c includes now only generic routines.
3036 Added WIN32 specific network routines to the
3037 lib/silcutil/win32/silcwin32net.c.
3039 * Added Unix specific utility functions from the
3040 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3042 * Added WIN32 SILC Scheduler to the file
3043 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3046 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3048 * Do not handle JOIN notify in the server if the target client
3049 is not registered (idata->registered == FALSE). The affected
3050 file is silcd/packet_receive.c.
3052 * Update the nickrec->founder in event_cumode in the Irssi SILC
3053 client. Affected file irssi/src/silc/core/silc-channels.c.
3055 * Fixed the CUMODE_CHANGE notify handling in the server when
3056 server and router are announcing their clients on channels.
3057 Now the mode changes are saved and notified correctly. The
3058 affected file is /silcd/packet_receive.c.
3060 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3061 They really did not replace the cache entry in the ID Cache.
3062 Now they do that. Affected file silcd/idlist.c.
3064 * Fixed the KICK notify handling in the Irssi SILC client to
3065 update the channel records so that the kicked client does not
3066 appear to be on the channel. The affected file is
3067 irssi/src/silc/core/silc-channels.c.
3069 * Always update the conn->current_channel when executing command
3070 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3072 * Fixed the KILL notify handling in Irssi SILC client to remove
3073 the killed client on all channels.
3075 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3077 * Fixed the silc_parse_command_line to remove extra spaces
3078 from the start and end of the arguments. Affected file is
3079 lib/silcutil/silcutil.c.
3081 * Cancel and free any active protocol in the function
3082 silc_server_close_connection. Affected file silcd/server.c.
3084 * Cancel and free any active protocol in the function
3085 silc_client_close_connction. Affected file is
3086 lib/silcclient/client.c.
3088 * Do not execute the KILL command for clients that are in
3089 history (ie. they are not in the network). Affected file is
3092 * Fixed KILL notify handling, client does not crash anymore.
3093 Affected file irssi/src/silc/core/silc-channels.c.
3095 * Reduced the default packet buffer size from 2048 to 1024 in
3096 lib/silccore/silcpacket.c.
3098 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3099 counter to the SKE context that is incresed when the SKE library
3100 performs async operation outside the library. If the outside
3101 process frees the SKE context and FREED status will be set
3102 and the library will detect after the sync operation that the
3103 libary is freed. The affected files are
3104 lib/silcske/silcske[_status].[ch].
3106 * Resolve the client entry information in the function
3107 silc_client_channel_message to assure that NULL pointer is not
3108 passed as client entry to the application. */
3110 * Fixed the task timeout calculation to assure that there is
3111 never negative timeouts. The affected file is
3112 lib/silcutil/silcschedule.c.
3114 * Fixed the channel user mode notification sending in server.
3115 It was sent point-to-point to the router (or to server by router)
3116 but it needs to be destined to a channel. The routines now
3117 supports sending the channel user mode notifys to the channels
3118 when announcing clients and channels. Affected files are
3119 silcd/server.c and silcd/packet_receive.c.
3121 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3122 It did not actually replace the old channel entry in the cache.
3123 Affected file lib/silcclient/client_notify.c.
3125 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3127 * Fixed a possible crash in silc_packet_send_prepare. It now
3128 assures always that there is enough space in the buffer and
3129 at the tail area of the buffer (for MAC).
3131 Fixed the inbound buffer reallocation in silc_packet_read.
3132 It was old code and did not handle the reallocation correctly.
3135 The affected file is lib/silccore/silcpacket.c.
3137 * Fixed buffer overflow in silc_parse_nickname in the file
3138 lib/silcutil/silcutil.c.
3140 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3142 * make install generates new server keys only if there is not
3145 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3147 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3148 Added check that if the NOREPLY is set then we will not send
3149 the away message. This avoids infinite loop of away messages
3150 if both clients are away. The affected file is
3151 lib/silcclient/client_prvmsg.c.
3153 * Fixed client crash if /NICK was given without arguments.
3154 Affected file lib/silcclient/command.c.
3156 * Server does not send the invite list in INVITE command back
3157 to the client if the list was not altered. Added this notion
3158 to the protocol spec as well. Affected file silcd/command.c.
3160 Fixed possible crash in INVITE command by checking the
3161 value of silc_server_get_client_route command.
3163 * Fixed the INVITE notify type handling. The arguments are now
3164 taken in correct order and client does not crash. The affected
3165 file is irssi/src/silc/core/silc-channels.c.
3167 Removed the "Inviting xxx to channel" message from the
3168 client library away and let the application handle it.
3169 Affected file lib/silcclient/command.c. Added that message
3170 to Irssi SILC client's message formats.
3172 * Fixed CMODE command crash in client. It now checks the
3173 amount of arguments correctly and does not crash. The affected
3174 file is lib/silcclient/command.c.
3176 * Do not create new channel automatically in silc_channels_join
3177 but check whether the channel by that name already exists.
3178 Affected file irssi/silc/core/silc-channels.c.
3180 * Do not send the SERVER_SIGNOFF to router if the disconnected
3181 entity was the router. Affected file silcd/server.c.
3183 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3184 SILC client as it was missing from there.
3186 Added the handling of the KICK notify to the Irssi SILC client
3187 as it was missing. Added "you have been kicked" message to
3188 Irssi SILC client's message modules formats.
3190 Added the handing of the KILL notify to the Irssi SILC client
3191 as it was missing. Added the kill message module formats
3194 The affected file is irssi/src/silc/core/silc-channels.c.
3196 * The router did not save the channel mode the server announced.
3197 Affected file silcd/packet_receive.c.
3199 * Fixed a possible crash in INFO command in server. If the
3200 server did not provide the server info it crashed. Affected
3201 file silcd/command.c.
3203 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3205 * Fixed the GETKEY command in the server to check also the
3206 global list. Otherwise the GETKEY would not work correctly
3207 in normal SILC server. Affected file silcd/command.c.
3209 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3211 * Fixed GETKEY crash, it crashed if the command did not succseed.
3213 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3215 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3216 is now real and not just an macro interface to GMP.
3218 Removed the entire GMP from the source tree and imported new
3219 NSS MPI library instead. Reason for removing GMP is that it is
3220 extremely large and compiles extremely slow. The NSS MPI
3221 is only a few files and compiles in less than 10 seconds.
3222 The speed is also about the same as GMP. The MPI is imported
3223 to lib/silcmath/mpi.
3225 If the system has GMP installed we will still use the GMP.
3226 If it is not then the NSS MPI will be compiled.
3228 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3230 * Merged a long nickname (127 characters long) crash bugfix from
3231 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3233 * Merged a freed memory reference bugfix from Irssi CVS tree.
3234 Affected file irssi/src/core/commands.c.
3236 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3238 * Added the server's public key sving and verification to the
3239 server when performing the SKE. This was missing and the
3240 remote server's (or router's) public key was accepted without
3241 checking whether we have it previously or trust it at all.
3242 Affected file silcd/protocol.c.
3244 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3246 * Check in the silc_server_timeout_remote if protocol is active
3247 and make sure that the protocol's final callback is called so
3248 that all memory if freed. Affected file silcd/server.c.
3250 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3252 * silc_server_whois_send_reply crashed the server if the nickname
3253 was 127 characters long. Affected file silcd/command.c.
3255 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3257 * Added sanity check to the silc_server_new_client. If the hostname
3258 is provided inside username then check that the provided hostname
3259 really is the same as the resolved one. If the hostname was not
3260 resolved then check it from the public key. Affected file is
3261 silcd/packet_receive.c.
3263 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3264 if the server disconnected us and the connection is not valid
3265 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3267 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3268 the library to the lib/silcutil/silcutil.[ch].
3270 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3272 * Close log file after open. Affected file
3273 lib/silcutil/silclog.c.
3275 * Check whether sock == NULL in silc_client_send_packet and return
3276 if it is. Affected file lib/silcclient/silcclient.c.
3278 * Check rec->entry == NULL in the Irssi SILC Client before
3279 sending the channel message. Affecte file is
3280 irssi/src/silc/core/silc-servers.c.
3282 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3284 * Merged a splitted window bugfix from Irssi CVS tree. The
3285 affected file is irssi/src/fe-text/textbuffer-view.c.
3287 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3288 It did not print nickname.
3290 * Improved the distributions system a bit.
3292 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3294 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3295 irssi/src/fe-text/gui-window.c.
3297 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3298 to in-active server. The affected file is
3299 irssi/src/silc/core/client_ops.c.
3301 * Resolve the client in USERS command reply if the entry does
3302 not have username resolved. The affected file is
3303 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3304 command to WHOIS command to really resolve stuff. The USERS
3305 is not used any more in any critical section so WHOIS can
3306 be used even though it might be slower than IDENTIFY.
3308 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3311 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3313 * Changed the protocol API a bit more consistent in the
3314 lib/silccore/silcprotocol.[ch].
3316 * Changed the following headers to ROBODoc format:
3318 lib/silccore/silcpayload.h
3319 lib/silccore/silcprotocol.h
3320 lib/silccore/silcsockconn.h
3322 All core library headers are now formatted.
3324 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Fixed a bug in Irssi SILC client; do not show that you are
3327 server/router operator if you really are not. Affected file is
3328 irssi/src/silc/core/client_ops.c.
3330 * Renamed silc_command_free_payload to silc_command_payload_free.
3331 Affected file lib/silccore/silccommand.h
3333 * Added silcmath.h to include the prototoypes of various routines
3334 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3337 * Changed the following headers to ROBODoc format:
3339 lib/silccore/silcchannel.h
3340 lib/silccore/silccommand.h
3341 lib/silccore/silcid.h
3342 lib/silccore/silcidcache.h
3343 lib/silccore/silcmode.h
3344 lib/silccore/silcnotify.h
3345 lib/silccore/silcpacket.h
3346 lib/silcmath/silcmath.h
3348 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3350 * Added checking to the server code not to start the server if
3351 ciphers and stuff are not configured properly. Affected files
3352 silcd/serverconfig.[h] and silcd/server.c.
3354 * Changed the layout of the header files of the public interfaces
3355 in the SILC libraries. The new layout supports ROBODoc
3356 documentation tool (and some others) so that it is easy to create
3357 a library reference manual. All the other headers and source
3358 code must still follow the CodingStyle document. Also source
3359 code must not include these ROBODoc stuffs, only the headers.
3360 Furthermore, all public interface headers must now be named
3361 by using `silc' prefix, example: silcapi.h, silccipher.h.
3362 Some files were renamed due to this. All the other headers
3363 must not be used as public interfaces. I will update the
3364 CodingStyle document later. Changed following headers, so far:
3366 lib/silcclient/silcapi.h
3367 lib/silccore/silcauth.h
3368 lib/silccore/silcprivate.h
3369 lib/silccrypt/silcdh.h
3371 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3375 * Removed silc_client_packet_send_flush from the client library
3376 as it is not needed. Affected file lib/silcclient/client.[ch].
3378 * Added printing of message of unresolved authentication method
3379 to the Irssi SILC client. Added it to the module formats.
3380 Removed the same message from the client library.
3382 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3384 * Added new distribution feature, DISTLABEL. Every distribution
3385 can define own preprocessor label that can be used in the
3386 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3387 file distributions, acconfig.h.pre and prepare.
3389 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3391 * Added Makefile.defines_int to include the actual definitions
3392 for Makefile.defines.in. Tested the new distribution system,
3393 created distributions and tested installation.
3395 * Added AWAY message printing to the Irssi SILC client. Added
3396 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3398 * Added SCONNECT command to call the SILC's CONNECT command.
3399 Cannot use CONNECT directly since Irssi uses that internally.
3400 Affected file irssi/src/silc/core/silc-servers.c.
3402 Added ACTION local command. It is same as ME command but takes
3403 the channel as mandatory argument.
3405 Rewrote some of the Irssi's help files to suite for SILC
3408 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3410 * Added Makefile.defines[.in] that should for now on be included
3411 in all Makefile.am file in the source tree. That file includes
3412 all common compilation definitions for SILC source tree.
3414 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3416 * Minor changes to the ./prepare script to change the package
3417 name according the distribution name to the configure.in.
3419 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3421 * Created new distribution system. Added file `distributions'
3422 that defines all the distributions that can be created out of
3423 the SILC source tree. The ./prepare script now reads that
3424 file to determine how to prepare the distributions. The
3425 first argument to the ./prepare is the name of the distribution
3426 and second is the version of the distribution. If given
3427 without arguments it creates the default (toolkit) distribution
3428 with the default version (defined in ./prepare).
3430 All Makefile.am files that are subject to the distributions
3431 are now named as Makefile.am.pre. These are ./Makefile.am
3432 and lib/Makefile.am. Others may be changed later.
3434 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3436 * Added invite list, ban list, some key management and connection
3437 error message printing to module formats in the Irssi SILC client.
3439 * Added new silc_client_set_away_message to set the away message
3440 that is back to the person who sent private message. The
3441 affected file lib/silcclient/silcapi.h and the
3442 lib/silcclient/client_prvmsg.c.
3444 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3446 * Fixed the private message sending in the Irssi SILC client,
3447 added local command KEY to the Irssi SILC client.
3449 Added key management and key agreement message formats to the
3450 irssi/src/fe-common/silc/module-formats.[ch].
3452 Added USERS (alias WHO) printing, server/router operator
3453 indication and LIST command printing to the module formats.
3455 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3457 * Fixed channel joining notify handling, cumode notify handling
3458 from Irssi SILC client.
3460 * Added SILC specific module-formats to the Irssi SILC client so
3461 that SILC specific message hilighting, colors etc is possible.
3462 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3464 Added channel mode, channel user mode, actions, notices,
3465 whois and whowas printing to the the module-formats.c.
3467 * Fixed a bug in channel deletion in the server. The channel
3468 is not left to the cache even if the channel founder auth mode
3469 is set when there are no users anymore on the channel. Affected
3470 file silcd/server.c.
3472 * The silc_net_localhost now resolves the entire hostname including
3473 the domain name. Affected file lib/silcutil/silcnet.c.
3475 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3477 * Changed the ask_passphrase client operation to be ascynchronous.
3478 It has now a completion callback and a context that the
3479 application must call after it has got the passphrase from
3480 the user. Affected files lib/silcclient/silcapi.h,
3481 lib/silcclient/protocol.c, lib/silcclient/command.c and
3484 Added SilcAskPassphrase callback that the application calls
3485 to deliver the passphrase to the library.
3487 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3488 The public key verification and especially a certificate
3489 verification is asynchronous procedure.
3491 Added new SILC_SKE_STATUS_PENDING status to indicate the
3492 request is pending and a callback will be called to finalize
3495 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3496 indicate that remote end did not send its public key (or
3497 certificate), even though we require it. Added check for this
3498 condition in the SKE. This was a security bug, now fixed.
3500 Defined new SilcSKEVerifyCbCompletion callback that is called
3501 when the verification process is completed.
3503 The affected files lib/silcske/silcske_status.h and
3504 lib/silcske/silcske.[ch].
3506 * Changed the verify_public_key client operation to be async
3507 as well. Defined SilcVerifyPublicKey callback that is used to
3508 indicate the success of the public key verification process.
3510 Changed the server and client to use the new async client
3513 * Changed the Irssi SILC client's internal scheduler to be called
3514 twice as many times as it used to be. As a result the client
3515 should be a bit faster now. Affected file is
3516 irssi/src/silc/core/silc-core.c.
3518 * Added support to Irssi SILC client of asynchronous public key
3519 verification and passphrase inquiry. Affected file is
3520 irssi/src/silc/core/silc-core.c.
3522 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3524 * Do not say "You have left channel %s" in client library.
3525 Moved it to the application. Affected files are
3526 lib/silcclient/command.c and silc/client_ops.c.
3528 * Fixed silc_client_get_clients. Command context was not
3529 duplicated and was freed memory in the callback. Affected
3530 file lib/silcclient/idlist.c.
3532 * Do not say "you are now talking..." on JOIN command in the
3533 client library. The appliation must handle it.
3535 * Do not say ".. changed topic to" in command reply in the
3536 client libary. The application must handle it.
3538 * Fixed TOPIC command sending in the client library.
3540 * Fixed a memory leak in silc_client_command_free in the file
3541 lib/silcclient/command.c.
3543 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3545 * Imported a modified version of Irssi client to the source tree.
3546 The Irssi will be used to create a new client called
3547 Irssi SILC. Imported to irssi/.
3549 Added silc_core_init_finish function to the Irssi. Affected
3550 file irssi/configure.in.
3552 A lot changes in the Makefile.ams around the irssi tree.
3554 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3556 * Do not rehash if the new size is same as the old size of the
3557 hash table, in the silc_hash_table_rehash*. The affected file
3558 lib/silcutil/silchashtable.c.
3560 * Replaced hash_table_del_by_context calls from the server
3561 (when channel->user_list and client->channels) to the
3562 hash_table_del as it is sufficient and faster.
3564 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3566 * Added silc_hash_table_list, silc_hash_table_get and the
3567 SilcHashTableList structure to provide an alternative way to
3568 traverse the hash table. The affected files are
3569 lib/silcutil/silchashtable.[ch].
3571 * Changed the server's idlist routines to use the hash table
3572 routines to optimize the code.
3574 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3576 * Replaced the client entry's `channel' list and channel entry's
3577 `user_list' list to hash tables for optimized lookup. Changed
3578 the code to use the hash table interface around the code.
3579 Affected file lib/silcd/idlist.[ch].
3581 * Added `auto_rehash' boolean argument to the function
3582 silc_hash_table_alloc to indicate whether the hash table should
3583 auto-rehash when it thinks is appropriate time. It will
3584 increase the hash table size if the there is twice as much
3585 entries in the table than the size of the table, and will
3586 decrease the size if there are twice as less entries than
3587 the size of the table.
3589 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3591 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3593 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3595 * silc_idcache_purge_by_context deletes the entry now by context
3596 as it is supposed to do. Affected file lib/silccore/idcache.c.
3598 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3599 client is not anymore valid (WHOWAS givens the info) and not
3600 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3602 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3604 * Removed the `data' and `data_len' arguments from the ID Cache
3605 interfaces and added `name' argument. ID Cache does not handle
3606 anymore the binary data only a names associated with given ID.
3608 * When hashing a Client ID with silc_hash_id the entire ID is
3609 not hashed anymore, instead only the hash of the Client ID is
3610 hashed. This way we can access the Client ID from the cache
3611 with Client ID but with the hash of the ID (which is a hash of
3612 the nickname) as well without any difference in performance.
3614 Added also silc_idcache_find_by_id_one_ext to do one on one
3615 searching when we have the actual ID. Added also function
3616 silc_hash_client_id_compare. The affected files are
3617 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
3619 * When hashing the name associated with a ID it is always done
3620 in lowercase. This way we can access the cache without worrying
3621 about case-sensitivity, even though, for example nicknames are
3624 * Fixed a bug in server with channel message sending. It put
3625 wrong ID type as destination ID. The affected file
3626 silcd/packet_send.c.
3628 * silc_idcache_del_by_context now deletes from all hash tables
3629 by context. Affected file lib/silccore/idcache.c.
3631 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3633 * Changed the client library to use the new ID Cache interface.
3634 Changes around the source tree.
3636 * Added silc_hash_table_rehash_ext to rehash with specific
3637 hash function. Affected file lib/silcutil/silchashtable.[ch].
3639 * Added silc_hash_string_compare to compare two strings in the
3640 hash table. Affected file lib/silcutil/silcutil.[ch].
3642 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3644 * Added new function silc_idcache_del_by_context into the
3645 lib/silccore/idcache.[ch].
3647 * Changed the server's ID list routines to use the new ID Cache
3648 interface. Changes around the source tree.
3650 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3652 * Added silc_hash_table_del[_by_context]_ext functions in to the
3653 lib/silcutil/silchashtable.[ch].
3655 Removed silc_hash_table_find_all* routines and added new
3656 silc_hash_table_find_foreach to replace them.
3658 Added silc_hash_table_replace_ext function as extended
3659 replacing function. Separated the simple hash table interface
3660 from the extended hash table interface in the file
3661 lib/silcutil/silchashtable.h.
3663 * Fixed minor bugs and changed it to use some of the new
3664 hash table functions in lib/silccore/idcache.c
3666 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3668 * Added new function silc_hash_table_find_all to return all keys
3669 in the hash table by the specified key. As the hash table is
3670 collision resistant it also makes it possible to have several
3671 duplicate keys in the hash table. This function may be used to
3672 find all of the keys from the hash.
3674 Added user_context arguments to the SilcHashFunction,
3675 SilcHashCompare and SilcHashDestructor to deliver user specified
3678 Added new fuctions silc_hash_table_find[_all]_ext to do
3679 extended lookup with specified hash and compare functions and
3680 specified user contexts.
3682 Added new function silc_hash_table_add_ext to add the key
3683 with specified hash function and user context.
3685 Added new function silc_hash_table_foreach to traverse all
3686 entrys in the hash table. Added SilcHashForeach callback
3689 Added new function silc_hash_table_del_by_context to delete
3690 the entry only if the context associated with the key matches.
3692 Affected files are lib/silcutil/silchashtable.[ch].
3694 * Removed silc_hash_[server/client/channel]_id and added just
3695 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
3696 silc_hash_id_compare to compare two ID's using as the hash table
3697 comparison function. Added also silc_hash_data to hash
3698 binary data and silc_hash_data_compare to compare it.
3700 * Removed silc_idlist_find_client_by_hash as it is not needed
3701 anymore. Affected file silcd/idlist.[ch].
3703 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
3704 to use internally the SilcHashTable. The new ID Cache is a lot
3705 faster than the old one. Some of the ID Cache interface was also
3706 rewritten and obsolete and stupid functions were removed.
3708 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3710 * Added entry_count field to the SilcHashTable to keep the number
3711 of the entries in the table. Implemented the function
3712 silc_hash_table_rehash. Added new function
3713 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
3715 Fixed a minor bug in silc_hash_table_free.
3717 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
3718 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
3719 into the lib/silcutil/silcutil.[ch].
3721 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3723 * Implemented a collision resistant hash table into the
3724 lib/silcutil/silchashtable[ch]. See the header and the source
3725 for the SilcHashTable API.
3727 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3729 * Merged dotconf version 1.0.2 into lib/dotconf.
3731 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3733 * Do not compile anything in lib/silcsim/* if the SIM support
3734 is not enabled. The tree should now compile without problems
3737 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3739 * Compiled the SILC under cygwin. Compiled and tested briefly
3740 without problems. More tests needed. The SIMs didn't compile
3743 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
3745 * Fixed possible crash in silc_get_username in the
3746 lib/silcutil/silcutil.c.
3748 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3750 * Fixed a va_arg in silc/client_ops.c.
3752 * Oops, RC5 routines were named AES and caused some problems
3753 when not using SIM's. Affected file lib/silccrypt/rc5.c.
3755 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3757 * Added new SilcIDIP structure into the lib/silccore/id.h and
3758 replaced the old `ip' fields from all SILC ID's to that type.
3759 This is a step towards IPv6 support.
3761 The silc_id_get_len takes now the ID as an extra argument.
3762 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
3763 both IPv4 and IPv6 based ID's.
3765 The affected files are lib/silccore/id.[ch] and other files
3766 around the tree using these routines.
3768 * Removed the ID length arguments in server from various
3769 silc_server_send_notify_* routines -> they are not needed
3772 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3774 * Fixed memory leak in silc_encode_pem_file in the file
3775 lib/silcutil/silcutil.c.
3777 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3779 * Check minor version as well in the SKE. Affected files are
3780 silcd/protocol.c and lib/silcclient/protocol.c.
3782 * Added --identifier option to the server so that an identifier
3783 can be when creating the public key for the server. Affected
3784 file is silcd/silcd.c.
3786 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
3787 lib/silccrypt/silcpkcs.c.
3789 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3791 * Register default ciphers and stuff when using -C option with
3792 the server. Affected file sildc/silcd.c.
3794 * Put back the servers public key filename format, it is better
3795 than the new one. For now, the client keys are saved with the
3796 new filename format. The affected file silc/client_ops.c.
3798 * Implemented the Cipher API for the rest of the ciphers that
3799 did not implement it or implemented it the wrong way.
3801 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3803 * Register default ciphers and stuff when using the -S option
3804 in the client. Affected file silc/silc.c. Same also when
3805 creating new key pair with -C option.
3807 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3809 * Fixed the silc_verify_public_key client operation function to
3810 save the public keys differently. The fingerprint is now
3811 used as filename and not the hostname. This way also the
3812 client keys are saved uniquely and not with hostnames. The
3813 affected file is silc/client_ops.c.
3815 * Trimmed the silc_hash_fingerprint function to remove extra
3816 whitespaces from the end of the fingerprint. The affected
3817 file is lib/silccrypt/silchash.c.
3821 * Added silc_cipher_register_default function to register all
3822 default ciphers. It can be used when configuration files
3823 does not exist and the application does not want any specific
3824 ciphers in any specific order.
3826 The SilcDList is now used as silc_cipher_list dynamically
3827 allocated cipher list. Removed the static list all together
3828 and now all ciphers must be allocated to the dynamic list.
3829 The silc_cipher_alloc routine was changed to check only the
3832 All silc_cipher_* routines that used to return int returns
3835 The affected files lib/silccrypt/silccrypt.[ch].
3837 * The same thing was done to silc_hash_* as for silc_cipher_*
3838 routines. Affected files lib/silccrypt/silchash.[ch].
3840 * The same thing was done to silc_pkcs_* as for silc_cipher_*
3841 routines. Affected files lib/silccrypt/silcpkcs.[ch].
3842 Added also silc_pkcs_[un]register[_default] functions.
3843 Removed the data_context from the PKCS API.
3845 * Added silc_hmac_register_default function to register default
3846 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
3847 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
3848 to unregister all hmacs at once.
3850 * Register the default ciphers, hash functions, PKCSs and HMACs
3851 if client's configuration file does not exist. The affected
3854 * The client did not load the hash functions from the SIM
3855 modules at all. Added support for this. Affected file is
3856 silc/clientconfig.c.
3858 * When decoding public key with silc_pkcs_public_key_decode, check
3859 the supported algorithm only if PKCS are registered. Affected
3860 file lib/silccrypt/silcpkcs.c. The same was done with the
3861 silc_pkcs_private_key_decode.
3863 * Fixed the SILC List routines to keep the list always in order.
3864 It used to change the list's order when traversing the list but
3865 not it preserves the order. Affected file lib/trq/silclist.h.
3867 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3869 * Added the client library to use the SilcSocketConnection's
3870 reference counter (by silc_socket_dup) to prevent the bug that
3871 the socket object may be freed underneath async operation.
3873 * The name resolv library checking fixes in the configure.in.pre.
3876 * Created new version of the protocol drafts for future
3877 development. The -03 drafts are the ones that will be changed
3878 in the trunk now and the -02 will remain as they are.
3880 * Send list of CUMODE notifys to the router when announcing
3881 the channel users to the router. Affected file silcd/server.c.
3882 If the router receiving channel founder CUMODE for a channel
3883 that already has channel founder it will send CUMODE notify
3884 to the sender to remove the channel founder rights from the
3885 announced client. Affected file silcd/packet_receive.c.
3887 * The CUMODE notify may now use Server ID as well as the entity
3888 who changes the mode. Updated protocool specs.
3890 * Updated INSTALL and README files.
3892 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3894 * New web pages in the http://silc.pspt.fi. The pages was
3899 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3901 * Implemented the [DenyConnectin] config section in the server.
3902 Added silc_server_config_denied_conn to check whether incoming
3903 connection is denied. Affected file silcd/serverconfig.[ch].
3905 * Do not check the ports when checking the incoming configuration
3906 data if the port is 0, meaning any. Affected file is
3907 silcd/serverconfig.c.
3909 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3911 * Fixed buffer overflow in silc_string_compare in the file
3912 lib/silcutil/silcutil.c.
3914 * Fixed double free in silc_server_command_leave in the file
3917 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3919 * Fixed the version checking in the server. Affected file is
3922 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3924 * Fixed the configuration data fetching when accepting new
3925 connections in the server. Affected file silcd/server.c.
3927 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3929 * Added `sender_entry' argument to the function
3930 silc_server_packet_relay_to_channel so that we can check
3931 whether some destination actually belongs to the same route
3932 the sender belongs (ie, we must not resend the packet to the
3933 sender). Affected file silcd/packet_send.[ch].
3935 * Added `servername' field to the SilcClientEntry in the server
3936 to hold the name of the server where client is from. Affected
3937 file is silcd/idlist.h.
3939 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3941 * Moved the channel message encrypting in the router betwen
3942 router connections from silc_server_channel_message to the
3943 silc_server_packet_relay_to_channel since we want to check
3944 whether we have anybody channel before encrypting anything.
3945 Affected files silcd/packet_[receive/send].c.
3947 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3949 * Fixed the [AdminConnection] server config section to support
3950 multiple entries. Affected file silcd/serverconfig.c.
3952 * Added support into the server to check the validity of the
3953 incoming connection before executing any KE or authentication
3956 * The connection configuration is now saved to the KE and
3957 connection auth protocol contexts and not fetched anymore in
3958 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
3960 * The local hosts listenning address and port is also resolved
3961 now when starting the server. We want to have the socket object
3962 to include the real address and port for the listener. Added
3963 new function silc_net_check_local_by_sock into the files
3964 lib/silcutil/silcnet.[ch].
3966 * Fixed a broadcast bug in server -> do not broadcast if we
3969 * Fixed a routing bug. Do not route broadcast packets ever.
3970 Broadcast packets must be processed always and not routed since
3971 they may be destined to some other host than yourself and thus
3972 would get routed without no good reason. Affected file is
3975 * Added function silc_server_config_is_primary_route to check
3976 whether primary router connection has been configured (a router
3977 configuration that we are initiating). If there is not, we
3978 will assume that there is only two routers in the SILC network
3979 and we will use the incoming router connection as our primary
3980 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
3982 * Changed the order of the broadcasting. Broadcast _after_ the
3983 packet has been processed not before. Affected file is
3986 * Fixed a [ClientConnection] parsing bug. The port was never
3987 parsed correctly thus resulting to port 0. Affected file
3988 silcd/serverconfig.c.
3990 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
3991 argument and did not set the broadcast packet flag. Affected
3992 file silcd/packet_send.c. Fixed same bug in the function
3993 silc_server_send_notify as well.
3995 * If we receive NEW_ID packet for our own ID in the server, ignore
3998 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4002 * Removed the nickname from the Private Message Payload.
4003 Updated the code and the protocol specs.
4005 * Updated protocol specs for submitting to the IETF.
4007 * Tweaked the Random Number Generator a bit. Affected file
4008 lib/silccrypt/silcrng.c. Exported a new function
4009 silc_rng_[global]_add_noise which can be used to add more
4012 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4014 * Do not parse packets with different timeout when protocol
4015 is active -> may cause problem with rekey. Affected file
4018 * When server receives signoff notify it must not create
4019 new channel key if the client is on any channels since the
4020 sender of the signoff notify will create it.
4022 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4024 * Added printing of error messages during SKE protocol from the
4025 failure packet sent by server during SKE. Affected file
4028 * Removed the client's failure_callback handling with timeout
4029 and handle it immediately when received.
4031 * The SKE library returned wrong type in SUCCESS and FAILURE
4032 packets. They must be 32 bit MSB not 16 bit MSB.
4034 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4036 * Ok, rewrote the logic of the re-key and now it seems to work.
4037 I tested it on high traffic with frequent re-keys without
4038 problems. Added hmac_receive (and renamed hmac to hmac_send)
4039 in SilcClientConnection in lib/silcclient/client.h and
4040 in SilcIDListData in silcd/idlist.h. Also, removed the
4041 SilcPacketParserContext's cipher and hmac fields as they are
4042 not needed anymore and actually caused some problems when
4043 the ciphers and hmac's changed underneath the packet parser.
4045 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4047 * If re-key protocol is active then process the incoming packets
4048 synchronously since we must assure that icoming packets encrypted
4049 with the old key is processed before the new keys is set to
4050 use. This is true other packets than for REKEY packets.
4051 Affected file silcd/server.c. The same was done to client library
4052 as well, affected file lib/silcclient/client.c.
4054 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4056 * Fixed bug in client and server to accept the force send if
4057 the packet is send from silc_[server/client]_packet_process
4058 function. Otherwise the packets are never delivered, oops.
4060 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4062 * Disable force sending of packets when REKEY protocol is active.
4063 We must assure that no packet is sent directly when rekey is
4064 performed. All packets must be sent through packet queue.
4065 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4066 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4067 function is silc_[server/client]_packet_send_real to check
4070 * Replaced the SIM paths from example config files to
4071 /usr/local/modules. Also, make install creates now
4072 /usr/local/silc/logs directory to hold all the SILC server
4075 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4077 * Made the configure.in.pre work on Solaris. Patch by salo.
4079 * Made all ciphers compatible with non-x86 machines. Defined
4080 CBC mode macros into lib/silccrypt/ciphers_def.h.
4082 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4084 * Fixed the make install.
4086 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4088 * When MAC computation fails the silc_packet_decrypt returned 0
4089 even though it was supposed to return -1. Fixed this. The
4090 affected file is lib/silccore/silcpacket.c.
4092 * Do not replace the config files in /etc/silc (in make install)
4093 if they already exist. Affected file ./Makefile.am.
4095 * Do not send re-key packets immediately but through packet queue.
4096 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4098 * Changed silc_net_check_host_by_sock to return FALSE if the
4099 IP/DNS could not be resolved. Though, it returns the IP address
4100 now even if it could not resolve it (but returns also FALSE).
4101 Affected file lib/silcutil/silcnet.[ch].
4103 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4105 * Added silc_pkcs_decode_identifier to decode the public key's
4106 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4107 Added also silc_pkcs_free_identifier. Added also new context
4108 SilcPublicKeyIdentifier.
4110 * Added -S option to the silc client. It is used to dump the
4111 contents of the specified public key file.
4113 * Changed the PKCS api to return the public key length when
4114 setting the public key.
4116 * Fixed a fatal bug in the public and private key file loading.
4117 Affected file lib/silccrypt/silcpkcs.c.
4119 * Execute the packet parsing for client with zero (0) timeout
4120 if the protocol is active. Affected file silcd/server.c.
4122 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4124 * Made the key generation options to the silcd program. Added
4125 -C option, equivalent to client's option.
4127 * Added new [ServerKeys] config section to the server. It
4128 configures the server's public and private key.
4130 * Defined generic Public Key Payload into the protocol
4131 specification to send specific type of public keys and
4134 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4135 public key or certificate.
4137 * Implemented the GETKEY command to the server and to the
4138 client library and on user interface.
4140 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4142 * Made preliminary `make install' work.

4171 SilcClientConnection structure; not needed. Affected file is
4172 lib/silcclient/client.h.
4176 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4178 * Do not ask whether user wants to use the negotiated private key
4179 for private messages, just use it. Affected file is
4180 silc/local_command.c.
4182 * Added `send_enc_key' and `enc_key_len' fields to the
4183 SilcIDListData structure since they are needed in the re-key
4184 phase. Affected file is silcd/idlist.[ch].
4186 * Implemented the simple re-key protocol into the server.

4198 the PFS is to be performed in the re-key. Affected file is
4201 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4203 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4204 int64 of at least the xintXX size. If void * is less that 4
4205 bytes uint32 * will be used. Defined bool as boolean.
4207 * Changed _ALL_ unsigned long and unsigned int to uint32,
4208 unsgined short to uint16 in the source tree.
4210 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4211 not handle clients that has entry->data.registered == FALSE.
4212 They are not in the network anymore. Affected file is
4215 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4217 * Implemented the sending of the SERVER_SIGNOFF notify in the
4218 server. Affected file is silcd/server.c.
4220 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4221 Added also silc_notify_payload_encode_args into the

4229 implemnted the printing of the SERVER_SIGNOFF info to the
4230 application. Affected file silc/client_ops.c.
4232 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4233 if the deleting was successful. Affected file silcd/idlist.[ch].
4235 * Added support for public key authentication in the connection
4236 authentication protocol in the client library. Affected file
4237 lib/silcclient/protocol.c.
4239 * Changed the server's silc_idlist_get_clients_by_* interface
4240 to support already allocated array so that new entries may be
4241 added to pre-allocated array. Affected file silcd/idlist.[ch].
4242 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4243 and command replies.
4245 * All command reply functions in the server now calls the
4246 pending command callback even if error occured. This way the
4247 error will be delivered to the client as well. Affected files
4248 silcd/command.c and silcd/command_reply.c.
4250 * Fixed INFO command to return local server's info if no server
4251 was provided. Affected file lib/silcclient/command.c.
4253 * Removed RESTART command for good. Updated the code and the

4257 Removed unsued task priorities. The affected files are
4258 lib/silcutil/silctask.[ch].
4260 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4262 * Moved the USERS printing from the library to the application.
4263 Affected files lib/silcclient/command.c and silc/client_ops.c.
4265 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4269 * Added channel key re-key support. The re-key is perfomed
4270 only by the router and is done once in an hour. Added `rekey'
4271 field to the SilcChannelEntry in the server. Affected files
4272 silcd/server.c and silcd/idlist.h.
4274 * Added silc_task_unregister_by_context into the file
4275 lib/silcutil/silctask.[ch].
4277 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4279 * Added SILC_UMODE_GONE mode to indicate when the client is not
4280 present in the SILC network. Added also support to the local
4281 command AWAY that will set this mode. Added support of showing
4282 "xxx is gone" in WHOIS command. The USERS command shows the
4283 gone status as well.
4285 * Fixed setting server and router operator privileges in the
4286 server's UMODE command. Affected file silcd/command.c.
4288 * Merged the SKE KE1 and KE2 payloads into one payload. The
4289 new KE payload is equivalent to the old KE2 payload.
4291 Cleaned up the SKE Start Payload parsing. It now uses the
4292 simple buffer unformatting to do the parsing. A lot faster
4295 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4296 to the SKE that is used to indicate whether both of the SKE
4297 parties should perform authentication. By default only the
4298 responder performs authentication. By setting this flag also
4299 the initiator must do authentication. By default it is unset
4300 since in normal SKE case, client to server connection, only
4301 the responder should do authentication. When doing SKE between
4302 two clients both should perform authentication. Updated the
4303 code and the protocol specs.
4305 * A little fix to IDENTIFY command in the server. Search the
4306 client first by hash not nickname. Affected file is
4309 * Fixed the silc_client_close_connection to support closing
4310 the client to client connections wihtout deleting too much
4311 data. Affected file lib/silcclient/client.c.
4313 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4314 are received if protocol used to be active but is not anymore
4315 the application would crash due to NULL pointer dereference.
4316 Affected files silcd/server.c and lib/silcclient/client.c.
4318 * Added `hash' field to the SilcClientConnection to include
4319 the hash function negotiated in the SKE protocol.
4321 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4322 to set the channel founder authentication data. A client can
4323 claim the founder rights later by providing the authentication
4324 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4325 This way the channel founder can regain the channel founder
4326 privileges even it is left the channel. This works only on
4327 local server and the client must be connected to the same
4328 server to be able to regain the founder rights. Updated the
4329 protocol specs accordingly.
4331 Added support to the CMODE command in the client to set the
4332 founder auth data. Read the README to see how to set it.
4334 Added support to the CUMODE command to claim the founder
4335 rights. Read the README to see how to do it.
4337 Added support for the founder authentication to the Channel
4338 Entry in the server. Affected file silcd/idlist.h.
4340 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4341 server's CMODE command. Affected file silcd/command.c.
4343 * Added the following new functions into lib/silccore/silcauth.[ch]:
4344 silc_auth_get_method and silc_auth_get_data.
4346 * The server now saves the remote hosts public key to the
4347 SilcIDListData pointer. Affected file silcd/protocol.c.
4349 * The normal server now does not remove the channel entry from
4350 the cache if the founder authentication data is set. It used
4351 to remove it if the founder was the last one on the channel on
4352 the server and left the channel. The auth data is saved and
4353 if the channel is re-joined later the old entry is used with
4354 the old auth data. Affected files silcd/command_reply.c and
4357 * Removed the `pkcs' field from the SilcIDListData structure
4358 in the server; it is not used. Affected file silcd/idlist.h.
4360 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4362 * Fixed packet processing on slow links. Partial packets were
4363 never re-processed because the incoming data buffer was cleared
4364 by the application. Application must not directly clear the
4365 sock->inbuf, the packet processing routines handle it. Fixed
4366 this in client library and in server.
4368 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4370 * Fixed the WHOIS and IDENTIFY send reply function to really
4371 check whether to send list or just one entry. Affected file
4374 * Cleaned up the LEAVE command's channel key distribution. The
4375 affected file silcd/command.c.
4377 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4378 can enforce the channel mode as well. In that case the ID
4379 includes the ID of the server. The code now enforces the
4380 mode change if the router have different mode than the server.
4382 * The notify client operation with CMODE_CHANGE notify can now
4383 return NULL client_entry pointer if the CMODE was not changed
4384 by client. Application must check for this.
4386 * Added <Server ID> argument to INFO command to support server
4387 info fetching by Server ID.
4389 * Added silc_server_announce_get_channel_users to get assembled
4390 packets of channel users of the specified channel. Affected
4391 file silcd/server.[ch].
4393 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4394 was freed underneath the ID Cache.
4396 * Re-announce clients when the server received CHANNEL_CHANGE
4397 notify from the router. Affected file silcd/packet_send.c.
4399 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4401 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4402 crashed since it did not handle the fact that there is no cipher
4403 called "3" and didn't check the error condition. Now fixed.
4405 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4406 flag. It can be used to send message requests.
4408 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4410 * Implemented the RESTART command in the client.
4412 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4413 notice type messages. Added notice printing to the user
4416 * The channel keys are not re-generated if the channel's mode
4417 is PRIVKEY, ie private key on the channel exists. Affected
4418 files silcd/server.c and silcd/command.c.
4420 * Fixed a little bug in channel message delivery when channel
4421 private keys are set in the server. Affected file is
4422 silcd/packet_send.c.
4424 * Changed the setting on channel->on_channel = TRUE from the
4425 silc_client_save_channel_key to the JOIN command reply. The
4426 key payload is not received if the private channel key is set.
4427 Affected file lib/silcclient/command_reply.c and the
4428 lib/silcclient/client_channel.c.
4430 * When the CMODE_CHANGE notify is sent and the channel private
4431 key mode is removed the channel key must be re-generated in
4432 other cells as well. Added this support for the router in the
4433 silcd/packet_receive.c.
4435 * Added new local command NOTICE to send notice message on
4436 channel. Affected file silc/local_command.[ch].
4438 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4440 * Added new local command ME to the client. It is used to send
4441 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4442 some action. Affected file silc/local_command.[ch].
4444 * Changed channel_message and private_message client operations
4445 to deliver the message flags to the application. Added also
4446 the `flags' arguments to the silc_client_send_channel_message
4447 and silc_client_send_private_message functions. Affected file
4450 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4452 * Redefined the Private Message Payload to support private message
4453 keys and to support the new private message flags. Updated
4454 the protocol specs. Flags makes it possible to have for example
4455 CTCP style messages.
4457 * Added new type SilcPrivateMessagePayload and defined an API
4458 for it in the lib/silcclient/silcprivate.[ch].
4460 * Tested private message private keys successfully. Tested the
4461 private message key set, unset and list commands with the new
4464 * Redefined the Channel Message Payload to include the channel
4465 message flags (equal with private message flags) to support
4466 for example CTCP style messages.
4468 * Defined some of the message (for channel and private message)
4469 flags. Updated the protocol specs and added the flags to the
4470 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4472 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4474 * Added SilcKeyAgreementStatus type to the key agreement routines
4475 to indicate the current status and error if one occured.
4476 The status types are defined in the lib/silcclient/silcapi.h.
4478 * Added new local command KEY that is used to set and unset private
4479 keys for channels, set and unset private keys for private messages
4480 with remote clients and to send key agreement requests and
4481 negotiate the key agreement protocol with remote client. The
4482 key agreement is supported only to negotiate private message keys,
4483 it currently cannot be used to negotiate private keys for channels,
4484 as it is not convenient for that purpose.
4486 * Fixed a minor pending callback setting bug in the function
4487 silc_client_get_client_by_id_resolve, now the function works.
4488 Affected file lib/silcclient/idlist.c.
4490 * Added function silc_net_get_local_port to get local bound
4491 port by socket. Added to lib/silcutil/silcnet.[ch].
4493 * Added `sockets' and `sockets_count' fields to the SilcClient
4494 object. They hold the sockets of the listenning sockets in
4495 the client. Listenning sockets may be for example the key
4496 agreement server. Affected file lib/silcclient/client.[ch].
4497 Added functions the silc_client_add_socket and the
4498 silc_client_del_socket. They are exported to the application
4501 * Added ~./silc/clientkeys to support other client's public keys.
4503 * Renamed verify_server_key client operation to verify_public_key
4504 and added one argument to indicate the type of the connection
4505 (server, client etc.).
4507 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4509 * Added silc_server_connection_auth_request to handle the
4510 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4511 silcd/packet_receive.[ch].
4513 * Added silc_server_send_connection_auth_request into the
4514 silcd/packet_send.c to send the connection auth request packet.
4516 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4519 * Fixed the public key authentication in responder side in the
4520 server. The `auth_data' pointer includes the SilcPublicKey
4521 not the path to the public key. Affected file silcd/protocol.c.
4523 * Implemented the public key authentication in the initiator side
4524 in the server. Affected file silcd/protocol.c.
4526 * Removed the [RedirectClient] config section from the server
4527 configuration. Is not needed and I don't want to implement it.
4529 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4531 * Cleaned up the CMODE command in the server. It now works
4532 correctly and supports all the modes defined in the protocol.
4533 Affected file is silcd/command.c.
4535 * Added `hmac_name' field to the SilcChannelEntry in the server
4536 to hold the default HMAC of the channel. It can be set when
4537 creating the channel (with JOIN command). Affected files
4540 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4541 type to indicate the change of the current cipher and hmac
4542 on the channel. Client can safely ignore the <cipher> argument
4543 (if it chooses to do so) since the CHANNEL_KEY packet will
4544 force the channel key change anyway. The <hmac> argument is
4545 important since the client is responsible of setting the new
4546 HMAC and the hmac key into use.
4548 * Fixed the CMODE command in the client library as well.
4550 * Tested CMODE command in router environment successfully.
4552 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4554 * Show the version of the remote client (or server) when connecting
4555 to the server. It is logged to the log file. Affected file
4556 is silcd/protocol.c.
4558 * Fixed the KILLED notify handling in the client library. The
4559 client must be removed from all channels when receiving the
4562 Also, do not remove the client entry when giving the KILL
4563 command but when the KILLED notify is received.
4565 * Removed silc_idlist_find_client_by_nickname from the server.
4566 Not needed anymore. Affected files silcd/idlist.[ch].
4568 * Implemented the CHANNEL_CHANGE notify type handling to the
4569 server. Affected file silcd/server.c.
4573 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * Added silc_server_send_notify_invite to send the INVITE
4576 notify between routers.
4578 * Implemented the INVITE command correctly to the server.

4587 * Added function silc_server_get_client_resolve to find the
4588 client entry by ID from all ID lists and then resolve it
4589 (using WHOIS) if it cannot be found. Affected file is
4592 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4594 * Implemented the BAN command to the client library.
4596 * The JOIN command in the server now checks the invite list
4599 * Changed the silc_command_reply_payload_encode_va and the
4600 silc_command_payload_encode_va to support that if argument is
4601 NULL it ignores and checks the next argument. Affected file
4602 lib/silccore/silccommand.c.
4604 * Added silc_server_send_notify_ban to send the BAN notify
4605 type between routers.
4607 * Chaned the silc_notify_payload_encode to support that if
4608 argument is NULL it ignores and checks the next argument.
4609 Affected file lib/silccore/silcnotify.c.
4611 * Tested ban lists in router environment successfully.
4613 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4615 * Implemented BAN command to the server, in silcd/command.[ch].
4617 * Removed the BAN and INVITE_LIST modes from the CMODE command
4620 * Added function silc_string_match to regex match two strings.
4621 Affected files lib/silcutil/silcutil.[ch].
4623 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4625 * Redefined parts of the SilcChannelEntry in the server to support
4626 the new ban and invite lists.
4628 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4630 * Redefined the INVITE command. The same command can be used to
4631 invite individuals to the channel but also to manage the invite
4632 list of the channel (to add to and remove from the invite list).
4633 Updated the protocol specs.
4635 * Added new command SILC_COMMAND_BAN that can be used to manage
4636 the ban list of the channel. Updated the protocol specs.
4638 * Removed the channel modes: the SILC_CMODE_BAN and the
4639 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
4640 in the CMODE command. The equivalent features are now available
4641 using INVITE and BAN commands. Updated the protocol specs.
4643 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
4644 in the network about change in the current ban list. The notify
4645 type is not used by the client.
4647 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
4648 support the invite lists.
4650 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4652 * Added new function silc_string_regexify that converts string
4653 including wildcard characters into regex string that can
4654 be used by the GNU regex library. Added into the file
4655 lib/silcutil/silcutil.[ch].
4657 Added silc_string_regex_combine to combine to regex strings
4658 into one so that they can be used as one regex string by
4659 the GNU regex library. Added into the file
4660 lib/silcutil/silcutil.[ch].
4662 Added silc_string_regex_match to match two strings. It returns
4663 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
4665 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4667 * Imported GNU regex to the soruce tree into lib/contrib.
4668 Fixed some compiler warning from the regex.c.
4670 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

4678 in the server, as the `nickname' argument may be binary data
4681 * Added silc_idlist_get_channels to return all channels from
4684 * Implemented LIST command to the server. Affected file is
4687 * Implemented the LIST command to the client library and on the
4690 * Added [<user count>] argument to the LIST command reply.
4691 With private channels the user count is not shown.
4693 * Updated TODO and README.
4695 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4697 * The client entry's data.registered must be TRUE even with
4698 global client entry on global client list. The data.registered
4699 is used to check whether the client is anymore in the network,
4700 for example with WHOWAS command so it must be valid.
4702 * Fixed the WHOWAS command in the server. It now actually works
4703 in router environment. Added function into silcd/command_reply.c
4704 silc_server_command_reply_whowas_save.
4706 * Added silc_idlist_purge function to the silcd/idlist.c
4707 to periodically purge the ID Cache.

4717 they were buggy because of the WHOWAS information.
4719 * Fixed local command MSG to handle the async resolving of
4720 the remote client properly. It used to fail the first MSG.
4721 Affected file silc/local_command.c.
4723 * Added `data_len' field to SilcIDCache context.
4725 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4727 * Update TODO. Todo in commands in the server.

4732 used by routers as broadcast packet to inform other routers
4733 about the changed user mode.
4735 Implemented the notify handling in the server. Affected file is
4736 silcd/packet_receive.c. Added the function
4737 silc_server_send_notify_umode to the silcd/packet_send.[ch].
4739 * Added new generic Channel Payload and deprecated the New Channel
4740 Payload. The New Channel Payload is now the generic Channel
4743 * Added new argument `mode' to the silc_server_send_new_channel
4744 as it is required in the Channel Payload now.
4746 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
4747 and created a new and real SilChannelPayload to represent the
4748 new generic Channel Payload. Implemented the encode/decode
4749 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
4751 * Added silc_server_get_client_channel_list to return the list
4752 of channels the client has joined for WHOIS command reply.
4753 Affected file silcd/server.[ch].
4755 * Implemented the channel list sending in the WHOIS command reply
4756 in server and in the client.
4758 Implemented the channel list displaying on the user interface
4759 as well. Affected file silc/client_ops.c.
4761 * Added silc_channel_payload_parse_list to parse list of Channel
4762 Payloads. It returns SilcDList list of SilcChannelPayloads.
4763 Client for example can use this function to parse the list of
4764 channels it receives in the WHOIS command reply. The caller
4765 must free the list by calling silc_channel_payload_list_free.
4766 Affected files lib/silccore/silcchannel.[ch].
4768 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Added one new argument <user mode> to the WHOIS command reply

4787 unknown command. Affected file silcd/command.c.
4789 * All server commands now handle the command identifier the right
4790 way when sending the command reply to the client. The client can
4791 use to identify the command replies with the identifier.
4793 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4795 * Added silc_server_get_client_route to resolve the route to
4796 the client indicated by the client ID. Affected file is
4799 * Added silc_server_relay_packet as general function to relay
4800 packet to arbitrary destination. This deprecates functions
4801 like _send_private_message_key, _relay_notify etc. Affected
4802 file is silcd/packet_send.[ch].
4804 Removed silc_server_send_key_agreement,
4805 silc_server_send_private_message_key and
4806 silc_server_packet_relay_notify functions from the file
4807 silcd/packet_send.[ch].
4811 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
4812 server. Affected file silcd/packet_receive.[ch].
4814 * Implemented the KILL command to the client. Implemented the
4815 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
4816 Affected files lib/silcclient/command[_reply].c and
4817 lib/silcclient/client_notify.c. Implemented the KILL notify
4818 printing in the user inteface.
4820 * Fixed a lot silc_parse_nick memory leaks from the client
4821 library in the file lib/silcclient/command.c.
4823 * Changed the silc_server_send_notify_on_channels's `sender'
4824 argument from SilcSocketConnection to SilcClientEntry to
4825 check the sender as entry and not as connection object and not
4826 to send to the client provided as argument. The affected file
4827 is silcd/packet_send.[ch].
4829 * The notify packets that are destined directly to the client used
4830 to not to be processed by the server. Now changed that and the
4831 server processes all notify packets. After relaying the packet
4832 to the client the notify packet is processed in the server.
4834 * The silc_server_free_client_data now checks whether there is
4835 pending outgoing traffic for the client and purges the data to
4836 the network before removing the client entry.
4838 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4840 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
4841 an client is killed from the SILC Network. Updated the protocol
4844 Added new function silc_server_send_notify_killed to the
4845 silcd/packet_send.[ch].
4847 * Added function silc_server_packet_relay_notify to relay notify
4848 packets that are destined directly to a client. In this case
4849 the server does not process the notify packets but merely relays
4850 it to the client. Affected file silcd/packet_send.[ch].
4852 Added also silc_server_packet_process_relay_notify to check
4853 whereto relay the notify. Affected file is
4854 silcd/packet_receive.[ch].
4856 * Implemented the KILL command to the server.
4860 * Added the backup schema desgined last fall to the protocol
4861 specs for everyone to see. The specification is in the
4862 *-spec-xx.txt draft and the packet type definitions for the
4863 backup routers is in *-pp-xx.txt draft. Thusly, added also
4864 new packet type SILC_PACKET_CELL_ROUTERS.
4866 * A big security problem in the implementation discovered. The
4867 signoff of an client did not cause new channel key generation
4868 which it of course should've done. The channel keys must be
4869 always re-generated when client leaves (or signoffs) the channel.
4870 The silc_server_remove_from_channels funtion now handles
4871 the channel key re-generation.
4873 * Added `sender' argument to the silc_server_send_notify_on_channels
4874 to not to send the client provided as argument. Affected file
4875 silcd/packet_send.[ch].
4877 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4879 * Implemented OPER and SILCOPER commands into the server and
4882 * Added silc_auth_verify and silc_auth_verify_data to verify
4883 the authentication directly from the authentication payload.
4884 It supports verifying both passphrase and public key based
4885 authentication. Affected file lib/silccore/silcauth.[ch].
4887 * Added `hash' field to the SilcIDListData structure. It is the
4888 hash negotiated in the SKE protocol. Affected file is
4891 * Slight redesigning of the SilcAuthPayload handling routines.
4892 Do not send SilcPKCS but SilcPublicKey as argument.
4894 * Implemented the public key authentication support to the
4895 serverconfig. The public key is loaded from the provided path
4896 and saved as authentication data to void * pointer. Thus,
4897 changed the unsigned char *auth_data to void *auth_data;
4899 * Fixed SHUTDOWN command to send the reply before the server
4900 is shutdown. :) Affected file silcd/command.c.
4902 * Fixed fatal bug in CONNECT command. The hostname was invalid
4903 memory and server crashed. Affected file silcd/command.c.
4905 * Fixed fatal bug in CLOSE command. The server_entry became
4906 invalid but was referenced later in the command. Affected file
4909 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4911 * Fixed fatal bug in failure packet handling. Server ignored
4912 the failure and thus crashed when it came.
4916 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4918 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
4919 that the command may be executed only once in (about) 2 seconds.
4920 The old SILC_CF_LAG flag is same but allows command bursts up
4921 to five before limiting.
4923 Added the support for CF_LAG and CF_LAG_STRICT flags to the
4924 server code. Various commands now includes the CF_LAG_STRICT
4925 flag to disallow any kind of miss-use of the command.
4927 * Fixed the silc_buffer_unformat to not to allocate any data
4928 if the length of the data is zero. It used to allocate the
4929 length + 1. Affected file lib/silcutil/silcbuffmt.c.
4931 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4933 * Changed the format of AdminConnection configuration section
4934 in the server. Added username of the admin to the format.
4935 Affected files silcd/serverconfig.[ch].
4937 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
4938 to return admin configuration data by host, username and/or
4941 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4943 * Implemented WHOWAS command to the server. Added the functions:
4945 silc_server_command_whowas_parse,
4946 silc_server_command_whowas_send_reply,
4947 silc_server_command_whowas_from_client and
4948 silc_server_command_whowas_from_server
4950 * Added <Client ID> argument to the WHOWAS command reply. Updated
4951 the protocol specs accordingly.
4953 * Implemented WHOWAS command and command_reply to the client
4956 Implemented the WHOWAS printing on the user interface.
4958 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4960 * Added new argument to the WHOWAS command reply, the real name.
4961 It is an optional argument. Updated the protocol specs.
4963 * Added SilcIDCacheDestructor callback that is registered when
4964 the SilcIDCache is allocated. The callback is called when
4965 an cache entry in the ID Cache expires, or is purged from the
4966 cache. Added into lib/silccore/idcache.[ch].
4968 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
4969 to destruct the client entries when the cache entry expires.
4970 Other ID Cache's in server and in the client library ignores
4973 * If the ID Cache entry's `expire' field is zero then the entry
4974 never expires. Added boolean `expire' argument to the
4975 silc_idcache_add function in the lib/silccore/idcache.[ch].
4976 If it is TRUE the default expiry value is used.
4978 * Added silc_server_free_client_data_timeout that is registered
4979 when client disconnects. By default for 5 minutes we preserve
4980 the client entry for history - for WHOWAS command.
4982 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4984 * Added support to the server to enforce that commands are not
4985 executed more than once in 2 seconds. If server receives
4986 commands from client more frequently, timeout is registered
4987 to process the commands. Affected file silcd/command.c.
4988 Added new function silc_server_command_process_timeout.
4990 * Changed NICK_NOTIFY handling in client library to check that
4991 if the client's nickname was changed, so there is no need to
4992 resolve anything from the server.
4994 * Removed error printing from the WHOIS and IDENTIFY commands.
4995 If error occurs then it is ignored silently in the client library.
4996 The application, however, may map the received error to
4997 human readable error string. The application currently maps
4998 the NO_SUCH_NICKNAME error to string.
5000 * Made the command status message public to the application. Moved
5001 them from lib/silcclient/command_reply.c to
5002 lib/silcclient/command_reply.h. The application can map the
5003 received command status to the string with the
5004 silc_client_command_status_message function.
5006 * Added check to the server to check that client's ID is same
5007 as the Source ID in the packet the client sent. They must
5010 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5012 * Added dist-bzip hook to the Makefile.am to make bzip2
5013 compressed distributions.
5015 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5017 * Server now enforces the maximum length for the nickname and
5018 the channel as protocol specification dictates. 128 bytes for
5019 nickname and 256 bytes for channel name.
5021 * Moved the WHOIS printing to the application. The client libary
5022 does not print out the WHOIS information anymore, the application
5023 must do it. Renamed silc_client_command_reply_whois_print to
5024 the silc_client_command_reply_whois_save.
5026 The client's idle time is also sent to the application now, and
5027 the idle is shown on screen.
5029 * Added silc_client_command_reply_identify_save to save the
5030 received IDENTIFY entries.
5032 * Do not check for channel private keys in message sending and
5033 reception if the channel does not have the PRIVKEY mode set.
5034 Affected file lib/silclient/client_channel.c.
5036 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5038 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5039 just surfaced after chaning the JOIN procedure.
5041 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5043 * Added silc_client_get_clients_by_list to get client entries
5044 from Client ID list, that is returned for example by JOIN
5045 and USERS command replies. The application should use this
5046 function for example when JOIN command reply is received to
5047 resolve the clients already on the channel (library does not
5048 do that anymore as USERS command reply is not used in the JOIN
5049 procedure anymore). Affected files lib/silcclient/silcapi.h and
5050 lib/silcclient/idlist.c.
5052 * JOIN command reply and USERS command reply returns now SilcBuffer
5053 pointers instead of unsigned char pointers when returning
5054 the client list and mode list.
5056 * Added <Client ID> argument to the JOIN command reply, mainly
5057 for the server to identify for which client the command was
5058 originally sent. Updated protocol specs accordingly.
5060 * Added SilcDlist private_key pointer to the SilcChannelEntry
5061 in the client to support the channel private keys. Affected
5062 file is lib/silcclient/idlist.h.
5064 * Added SilcChannelPrivateKey argument to the function
5065 silc_client_send_channel_message so that application can choose
5066 to use specific private ke if it wants to. If it is not provided,
5067 the normal channel key is used, unless private keys are set.
5068 In this case the first (key that was added first) is used
5069 as the encryption key.
5071 * Implemented the support for channel private key handling.
5072 Implemented the following functions:
5074 silc_client_add_channel_private_key,
5075 silc_client_del_channel_private_keys,
5076 silc_client_del_channel_private_key,
5077 silc_client_list_channel_private_keys and
5078 silc_client_free_channel_private_keys
5080 Affected file lib/silcclient/client_channel.c.
5082 * Added the support for the private keys in the channel message
5083 sending and encryption and in the message reception and
5084 decryption. Affected funtions are
5085 silc_client_send_channel_message and silc_client_channel_message.
5087 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5089 * Added SKE's key verify callback to the client library's
5090 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5092 * Removed the statement that server (or router) must send USERS
5093 command reply when joining to the channel so that the client
5094 knows who are on the channel. Instead, the client list and
5095 client's mode list is now sent in the JOIN command reply to the
5096 client who joined channel. This is better solution.
5098 * Added function silc_server_get_users_on_channel and function
5099 silc_server_save_users_on_channel to the silcd/server.[ch].
5101 * Removed function silc_server_command_send_users from the
5104 * Do not show topic on the client library anymore. The topic is
5105 sent in the command reply notify to the application and the
5106 application must show the topic now.
5108 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5110 * Added client searching by nickname hash into the IDENTIFY and
5111 WHOIS commands in the server as they were clearly missing from
5112 them. Affected file is silcd/command.c.
5114 * Fixed a bug in private message receiving in the client library.
5115 The remote ID was freed and it wasn't supposed, now it is
5118 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5120 * Minor fix to the channel payload; allocate the data area, as it
5121 needs to be of specific length.
5123 * If the key agreement port is zero then the operating
5124 system will define the bound port. Affected files are
5125 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5127 * Added new function silc_channel_payload_decrypt into the file
5128 lib/silccore/silcchannel.[ch].
5130 * Moved the channel message etc, check from silc_packet_decrypt
5131 to applications. The library calls now a generic
5132 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5133 when the packet is either normal or special. This was done to
5134 allow more wide range of checking that was not allowed when
5135 the code was in library. Now applications can do virtually any
5136 checks to the packet and return to the library the decision how
5137 the packet should be processed. Affected files are
5138 lib/silccore/silcpacket.[ch].
5140 Added silc_server_packet_decrypt_check to the server and
5141 silc_client_packet_decrypt_check to the client library.
5143 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5144 to send with specified source and destination information.
5146 * Channel message delivery between routers was broken after the
5147 channel key distribution was fixed earlier. The channel key
5148 was used be to distributed to other routers as well which is not
5149 allowed by the protocol. Now this is fixed and channel keys
5150 really are cell specific and the channel message delivery between
5151 routers comply with the protocol specification.
5153 * Fixed various commands in server to check also the global list
5154 for the channel entry and not just the local list. The affected
5155 file silcd/command.c.
5157 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Added assert()s to buffer formatting and unformatting routines
5160 to assert (if --enable-debug) when error occurs. Affected
5161 file: lib/silcutil/silcbuffmt.c.
5163 * Changed to auto-reconnect to check whether the remote host is
5164 router and register the re-connect timeout if it is. It used
5165 to check that whether we are normal server, but router must do
5166 auto-reconnect with another router as well. Affected file
5169 * Removed the [<key len>] option from CMODE command as the cipher
5170 name decides the key length, nowadays. See the defined ciphers
5171 from the protocol specification.
5173 * Added [<hmac>] option to the CMODE command to define the HMAC
5174 for the channel. Added SILC_CMODE_HMAC channel mode.
5176 * Added [<hmac>] option for the JOIN command so that user can
5177 select which HMAC is used to compute the MACs of the channel
5180 * Added Hmac field to the Channel Message Payload. The integrity
5181 of plaintext channel messages are now protected by computing
5182 MAC of the message and attaching the MAC to the payload. The
5183 MAC is encrypted. Now, it is clear that this causes some
5184 overhead to the size of the packet but rationale for this is that
5185 now the receiver can verify whether the channel message decrypted
5186 correctly and also when private keys are set for the channel the
5187 receiver can decrypt the packet with several keys and check from
5188 the MAC which key decrypted the message correctly.
5190 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5191 lib/silccrypt/silccipher.[ch].
5193 * Added silc_hash_len to return the digest length into the
5194 lib/silcrypt/silchash.[ch].
5196 * Rewrote parts of Silc Channel Payload interface in the
5197 lib/silccore/silcchannel.[ch]. The encode function now also
5198 encrypts the packet and parse function decrypts it.
5200 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5202 * Fixed a minor formatting bug in the SKE's key material processing.
5203 It actually might have processed the keys wrong way resulting
5206 * Redefined the mandatory HMAC algorithms and added new algorithms.
5207 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5208 and hmac-md5 truncated to 96 bits. The mandatory is now
5209 hmac-sha1-96. Rest are optional (including the one that used
5210 to be mandatory). Rationale for this is that the truncated HMAC
5211 length is sufficient from security point of view and can actually
5212 make the attack against the HMAC harder. Also, the truncated
5213 HMAC causes less overhead to the packets. See the RFC2104 for
5216 * Added new [hmac] configuration section. The SKE used to use
5217 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5218 is of course wrong. The official names that must be proposed in
5219 the SKE are the ones defined in the protocol specification
5220 (hmac-sha1-96 for example). The user can configure any hmac
5221 using any hash function configured in the [hash] section. At
5222 least, the mandatory must be configured.
5224 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5226 * Added HMAC list to the SKE proposal list. It has now both
5227 hash algorithm list and HMAC list. This makes the protocol
5228 incompatible with previous versions. The SKE now seems to work
5229 the way it is supposed to work, for the first time actually.
5231 * Defined plain Hash algorithms to the protocol specification.
5234 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5236 * Implemented support for key agreement packets into the server.
5237 Added functions silc_server_key_agreement and
5238 silc_server_send_key_agreement. Other than these functions,
5239 server has nothing to do with this packet.
5241 * Added support for private message key packets into the server.
5242 Added functions silc_server_private_message_key and
5243 silc_server_send_private_message_key.
5247 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5248 called in the protocol's final callback instead in the END
5249 protocol state. This makes a little more sense and in the same
5250 time in client we can use the same protocol routines for normal
5251 key exchange and to key agreement packet handling as well.
5253 * Added to both client's and server's KE protocol context the
5254 SilcSKEKeyMaterial pointer to save the key material. We will
5255 bring the key material to the protocol's final callback by doing
5256 this. The final callback must free the key material.
5258 * Added SKE's packet_send callback into client's KE protocol
5259 context so that the caller can choose what packet sending function
5260 is used. This way we can use different packet sending when
5261 doing normal SKE when doing key agreement packet handling (in
5262 the key agreement packet handling we do not want to encrypt
5265 * Implemented the responder side of the key agreement routines
5266 in the client. The client can now bind to specified port and
5267 accept incoming key negotiation. The key material is passed
5268 to the application after the protocol is over.
5270 * Implemented the processing of incoming Key Agreement packet
5271 in the client. Added function silc_client_key_agreement to
5274 * Implemented the intiator side of the key agreement routines
5275 in the client. The client can now initiate key agreement with
5276 another remote client. The key material is passed to the
5277 application after the protocol is over.
5279 * Created client_keyagr.c to include all the key agreement
5282 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5283 SILC_TASK_CALLBACK except that it is not static.
5285 * Created client_notify.c and moved the Notify packet handling
5286 from the client.[ch] into that file.
5288 * Created client_prvmsg.c and moved all private message and
5289 private message key routines from the client.[ch] into that file.
5291 * Create client_channel.c and moved all channel message and
5292 channel private key routines from the client.[ch] into that file.
5294 * Changed silc_client_get_client_by_id_resolve to resolve with
5295 WHOIS command instead of IDENTIFY command, in the file
5296 lib/silclient/idlist.c.
5298 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5300 * Implemented the SKE's responder side to the Client library.
5302 * When FAILURE is received to the protocol do not trust it
5303 blindly. Register a timeout to wait whether the remote closes
5304 the connection as it should do it, only after that process the
5305 actual failure. This was changed to both client and server.
5307 * Added client_internal.h to include some of the structures
5308 there instead of client.h in lib/silcclient/.
5310 * Added function silc_task_unregister_by_callback to unregister
5311 timeouts by the callback function.
5313 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5315 * Some "Incomplete WHOIS info" errors has been appearing on the
5316 log files. Took away the entry->userinfo check from WHOIS
5317 reply sending. The entry->userinfo is now " " if client did not
5318 provide one. I thought this was fixed earlier but something
5319 is wrong still. Let's see if the error still appears.
5321 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5323 * Fixed a minor bug in the login when the channel key is
5324 re-generated in the server. It used to generate the key in
5325 wrong order and thus caused problems in the channel traffic.
5327 * Fixed a minor bug in channel key distsribution after
5328 KICK command. The key was not sent to the router even though
5331 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Added silc_ske_process_key_material_data as generic routine
5334 to process any key material as the SILC protocol dictates. The
5335 function is used by the actual SKE library but can be used by
5336 applications as well. This relates to the private message keys
5337 and the channel private keys since they must be processed the
5338 same way the normal SILC session keys. The protocol dictates
5339 this. Affected files: lib/silcske/silcske.[ch].
5341 Added also silc_ske_free_key_material to free the
5342 SilcSKEKeyMaterial structure.
5344 * Defined silc_cipher_set_key function to set the key for
5345 cipher without using the object's method function. The affected
5346 files: lib/silccrypt/silccipher.[ch].
5348 * Implemented silc silc_client_add_private_message_key,
5349 silc_client_add_private_message_key_ske,
5350 silc_client_del_private_message_key,
5351 silc_client_list_private_message_keys and
5352 silc_client_free_private_message_keys functions in the
5355 Added functions silc_client_send_private_message_key to send
5356 the Private Message Key payload and silc_client_private_message_key
5357 to handle incoming Private Message Key payload.
5359 * Added Cipher field to the Private Message Key payload to set
5360 the cipher to be used. If ignored, the default cipher defined
5361 in the SILC protocol (aes-256-cbc) is used.
5363 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5365 * Removed lib/silcclient/ops.h file.
5367 Redefined parts of the SILC Client Library API. Created new
5368 file silcapi.h that deprecates the ops.h file and defines the
5369 published Client Library API. Defined also private message key
5370 API and channel private key API into the file.
5372 This is the file that the application must include from the
5373 SILC Client Library. Other files need not be included by
5374 the application anymore.
5376 * Added new key_agreement client operation callback and also
5377 defined the Key Agreement library API for the application.
5379 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5381 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5382 is used by clients to request key negotiation between another
5383 client in the SILC network. If the negotiation is started it
5384 is performed using the SKE protocol. The result of the
5385 negotiation, the secret key material, can be used for example
5386 as private message key.
5388 Implemented the Key Agreement payload into the files
5389 lib/silccore/silauth.[ch].
5391 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5393 * Redefined ciphers for the SILC protocol. Added some new ciphers
5394 and defined the key lengths for the algorithms. Changed the
5395 code accordingly. The default key length is now 256 bits.
5397 * Fixed SKE key distribution function silc_ske_process_key_material
5398 when the key length is more than 128 bits. The default key
5399 length in SILC is now 256 bits.
5401 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5402 to indicate unsupported algorithm.
5404 * Renamed rijndael.c to aes.c and all functions as well.
5406 * Fixed a long standing channel key setting bug in client library.
5407 Weird that it has never surfaced before.
5409 * Fixed bug in channel deletion. If the entire channel is removed
5410 then it must also delete the references of the channel entry
5411 from the client's channel list as the client's channel entry and
5412 the channel's client entry share same memory.
5414 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5416 * Implemented CONNECT and SHUTDOWN commands in the client.
5418 * Implemented CLOSE command to the client.
5420 * Added the function silc_idlist_find_server_by_name into the
5421 files silcd/idlist.[ch].
5423 Added the function silc_idlist_find_server_by_conn into the
5424 files silcd/idlist.[ch].
5426 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5428 * DIE command was renamed to SHUTDOWN. Updated the both code
5431 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5432 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5434 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5437 * Added function silc_server_create_connection function to create
5438 connection to remote router. My server implementation actually
5439 does not allow router to connect to normal server (it expects
5440 that normal server always initiates the connection to the router)
5441 so the CONNECT command is only good for connecting to another
5444 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5446 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5447 or some other client was kicked from the channel.
5449 Implemented the handling of the notify type to both client
5452 Implemented silc_server_send_notify_kicked to send the KICKED
5453 notify. It is used to send it to the server's primary router.
5455 * Implemented the KICK command into server and client.
5457 * Added `query' argument to the silc_idlist_get_client function
5458 to indicate whether to query the client from server or not if
5461 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5462 to indicate that the client is not channel founder.
5466 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5468 * Removed the rng context from SilcPacketContext structure and
5469 changed that the packet routine uses the Global RNG API.
5471 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5473 * Added support for quit message that client can "leave" on the
5474 channel when it quits the SILC. It is ditributed inside the
5475 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5477 Added silc_server_free_client_data that will take the
5478 signoff message as argument.
5480 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5482 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5484 * Updated parts of the protocol specification to keep it up
5487 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5489 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5490 payloads in one packet.
5492 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5493 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5494 use now the new List flag.
5496 * Also deprecated the following packet types: REPLACE_ID,
5497 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5499 * Added list support for Notify packet in server.
5501 * Added silc_server_send_notify_channel_change to send the
5502 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5503 the silc_server_send_replace_id.
5505 * Added silc_server_send_notify_nick_change to send the
5506 NICK_CHANGE notify type. Deprecates the function
5507 silc_server_send_replace_id.
5509 * Added silc_server_send_notify_join to send the JOIN notify type.
5510 Deprecates the function silc_server_send_new_channel_user.
5512 * Added silc_server_send_notify_leave to send LEAVE notify type.
5513 Deprecates the function silc_server_send_remove_channel_user.
5515 * Added silc_server_send_notify_cmode and
5516 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5517 types. Deprecates the silc_server_send_set_mode function.
5519 * Added SERVER_SIGNOFF notify type to indicate that server has
5520 quit. This means that all clients on the channel from that
5521 server will drop. This can be also used when netsplit happens.
5523 Deprecated REMOVE_ID packet type since it is not needed anymore
5526 Added silc_server_send_notify_server_signoff to send the
5527 SERVER_SIGNOFF notify type. Deprecates the function
5528 silc_server_send_remove_id.
5530 Added also silc_server_send_notify_signoff to send the
5531 SIGNOFF notify type.
5533 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5534 SILC protocol from this day on. Changed the protocol
5535 specification as well.
5537 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5538 notify type. It is used between routers to notify about
5539 topic changes on a channel.
5541 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5544 * Partly updated the protocol specification to comply with the
5545 changes now made. It is still though a bit outdated.
5547 * The JOIN notify type now takes one extra argument <Channel ID>.
5548 The packet used to be destined to the channel but now the
5549 JOIN type may be sent as list thus it is impossible to
5550 destine it to any specific channel. By adding this argument
5551 it is again possible.
5553 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5555 * Added CREDITS file. The CHANGES and CREDITS file will appear
5556 in the distribution as well.
5558 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5560 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5561 types in the server's silcd/packet_receive.c.
5563 * Implemented CMODE and CUMODE to work in router environment.
5565 * Fixed minor encoding and decoding buglet from the
5566 lib/silccore/silcmode.c.
5568 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5571 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5573 * Changed all SilcConfigServer* and silc_config_server* to
5574 SilcServerConfig* and silc_server_config*, respectively.
5577 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5579 * Associated the ID (client or server ID) to the Authentication
5580 Payload to avoid any possibility of forging. Updated the
5581 protocol specification and the code accordingly.
5583 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5585 * The RSA key length is now save to the RsaKey context in the
5586 key generation process in lib/silccrypt/rsa.c. The key length
5587 is now used to figure out the maximum size of the block allowed
5588 to be encrypted/signed.
5590 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5591 is equivalent to the silc_mp_mp2bin but does not allocate any
5594 * Changed silc_mp_mp2bin API to take length argument. If it is
5595 non-zero then the buffer is allocated that large. If zero, then
5596 the size is approximated using silc_mp_sizeinbase, which however
5599 * Created Global RNG API which is global RNG that application can
5600 initialize. After initializing, any routine anywhere in the
5601 code (including library) can use RNG without allocating a new
5602 RNG object. This was done to allow this sort of use of the
5603 RNG in code that has no chance to allocate RNG object. All
5604 applications currently allocate this and many routines in the
5605 library use this. Affected file lib/silccrypt/silcrng.[ch].
5607 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
5608 it to use the Global RNG API.
5610 * Defined Authentication Payload into protocol specification that
5611 is used during SILC session to authenticate entities. It is
5612 used for example by client to authenticate itself to the server
5613 to obtain server operator privileges.
5615 Implemented this payload into the lib/silccore/silcauth.[ch].
5616 Implemented also routines for public key based authentication
5617 as the new protocol specification dictates.
5619 Moved definitions of different authentication methods from
5620 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
5622 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
5623 silc_pkcs_verify and silc_pkcs_sign_with_hash and
5624 silc_pkcs_verify_with_hash functions into the file
5625 lib/silccrypt/silcpkcs.[ch].
5627 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5629 * The client entry's userinfo pointer must be always valid.
5630 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
5631 will fail since it requires the userinfo. Now, the userinfo
5632 is allocated as "" if actual userinfo does not exist. Actually,
5633 it must exist and it is totally Ok to drop client connections
5634 that does not announce the userinfo. However, we will make
5635 this workaround for now.
5637 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
5638 to return the remote port by socket.
5640 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5642 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
5643 SILC_SERVER_PENDING_EXEC and added an new macro
5644 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
5645 data or when error occurs while processing the pending command.
5647 Added new argument `destructor' into silc_server_command_pending
5648 and to the SilcServerCommandPending object. This destructor is
5649 now called after calling the pending callback or if error occurs
5650 immediately. If error occurs the actual pending callback won't
5651 be called at all - only the destructor. The destructor may be
5652 NULL if destructor is not needed.
5654 All this applies for client library code as well. Similar
5655 changes were made there as well for the pending commands.
5657 In the client, the application must now allocate the
5658 SilcClientCommandContext with the silc_client_command_alloc
5661 * Added reference counter to the SilcServerCommandContext. Added
5662 function silc_server_command_alloc and silc_server_command_dup
5665 Same type of functions added to the client library for the same
5668 * Removed the cmd_ident from IDListData away since it is now
5669 global for all connections. It is the command identifier used
5670 in command sending and with pending commands. The affected file
5673 * Added reference counter to the SilcSocketConnection objecet to
5674 indicate the usage count of the object. The object won't be
5675 freed untill the reference counter hits zero. Currently only
5676 server uses this, and client ignores it. The client must be
5677 set to use this too later. The affected files are
5678 lib/silccore/silcsockconn.[ch]. Added also the function
5679 silc_socket_dup to increase the reference counter.
5681 This was mainly added because it is possible that the socket
5682 is removed underneath of pending command or other async
5683 operation. Now it won't be free'd and proper DISCONNECTING
5684 flags, etc. can be set to avoid sending data to connection that
5685 is not valid anymore.
5687 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
5688 the connection. After that it sets SILC_SET_DISCONNECTED.
5689 It is, however, possible that the socket data is not still freed.
5690 The silc_server_packet_process now checks that data is not
5691 read or written to connection that is DISCONNECTED. The socket
5692 get's freed when the reference counter hits zero.
5694 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5696 * Changed the client operation API: channel_message operation's
5697 `sender' is now the client entry of the sender, not the nickname
5698 and the `channel' is the channel entry, not the channel name.
5700 In the private_message operation the `sender' is now also the
5701 client entry of the sender not the nickname.
5703 Affected file is lib/silcclient/ops.h and all applications
5704 using the client operations.
5706 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5708 * Moved the calling of ops->connect() from connect_to_server_final
5709 into receive_new_id functin since that is the point when the
5710 client is actually allowed to send traffic to network. The
5711 affected file is lib/silcclient/client.c.
5713 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5715 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
5716 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
5717 (if needs broadcasting) instead of broadcasting the packets one
5718 by one which would make a burst in the network traffic.
5720 * Added `broadcast' argument to the functions in silcd/server.[ch]
5721 silc_server_create_new_channel[_with_id] to indicate whether
5722 to send New Channel packet to primary router.
5724 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5726 * Added new function into the silcd/server.[ch] files:
5727 silc_server_create_new_channel_with_id to create new channel with
5728 already existing Channel ID.
5730 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
5731 lib/silccore/silcpacket.h. This packet is used t send list of
5732 Set Mode payloads inside one packet. Server uses this to set
5733 the modes for the channels and clients on those channels, that it
5734 announced to the router when it connected to it. The protocol
5735 specification has been updated accordingly.
5737 * The silc_server_new_channel did not handle the packet coming
5738 from normal server as it normally does not send that. However,
5739 when it announces its channels it does send it. Implemented
5740 the support for that.
5742 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
5743 into the file lib/silccore/id.h.
5745 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5747 * Fixed memory leaks in the functions silc_idlist_del_client,
5748 silc_idlist_del_channel and silc_idlist_del_server in the file
5749 silcd/idlist.c. All of those leaked like a sieve.
5751 * Fixed some small memory leaks in the client's function
5752 silc_client_notify_by_server.
5754 * Added functions into silcd/server.c: silc_server_announce_clients,
5755 silc_server_announce_channels and silc_server_announce_server.
5756 These functions are used by normal and router server to announce
5757 to its primary router about clients, channels and servers (when
5758 router) that we own. This is done after we've connected to the
5761 These functions effectively implements the following packet types:
5762 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
5763 and SILC_PACKET_NEW_ID_LIST.
5765 * Added new functions into the silcd/packet_receive.[ch]:
5766 silc_server_new_id_list, silc_server_new_channel_list and
5767 silc_server_new_channel_user_list to handle the incoming
5768 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
5770 * Added support of changing Channel ID in the function
5771 silc_server_replace_id. If the server that announces a channel
5772 to the router already exists in the router (with same name but
5773 with different Channel ID), router is responsible to send
5774 Replace ID packet to the server and force the server to change
5775 the Channel ID to the one router has.
5777 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
5778 client that the Channel ID has been changed by the router. The
5779 normal server sends this to the client. Client must start using
5780 the new Channel ID as the channel's ID.
5782 Implemented handling of this new type into lib/silcclient/client.c
5783 into the function silc_client_notify_by_server.
5785 * Added new function silc_idlist_replace_channel_id into the files
5786 silcd/idlist.[ch] to replace the Channel ID.
5788 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5790 * Call silc_server_command_identify_check always when processing
5791 the IDENTIFY command in silcd/command.c
5793 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5795 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
5796 send keepalive packets. The packet can be sent by clients,
5797 servers and routers.
5799 Added function silc_socket_set_heartbeat into the file
5800 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
5801 If not set, the heartbeat is not performed. The actual
5802 heartbeat is implemented in the low level socket connection
5803 library. However, application is responsible of actually
5806 Added silc_server_send_heartbeat to send the actual heartbeat
5807 packet into silcd/packet_send.[ch]. Server now performs
5808 keepalive with all connections.
5810 * Added silc_task_get_first function into lib/silcutil/silctask.c
5811 to return the timeout task with shortest timeout. There was a bug
5812 in task unregistration that caused problems. TODO has been
5813 updated to include that task system must be rewritten.
5815 * The client library will now resolve the client information when
5816 receiving JOIN notify from server for client that we know but
5817 have incomplete information.
5819 * Rewrote parts of silc_server_remove_from_channels and
5820 silc_server_remove_from_one_channel as they did not remove the
5821 channel in some circumstances even though they should've.
5823 * Encryption problem encountered in server:
5825 The LEAVE command used to send the Channel Key packet to the
5826 router immediately after generating it. However, the code
5827 had earlier sent Remove Channel user packet but not immediately,
5828 ie. it was put to queue. The order of packets in the router
5829 was that Channel Key packet was first and Remove Channel User
5830 packet was second, even though they were encrypted in the
5831 reverse order. For this reason, MAC check failed. Now, this
5832 is fixed by not sending the Channel Key packet immediately but
5833 putting it to queue. However, this is more fundamental problem:
5834 packets that are in queue should actually not be encrypted
5835 because packets that are sent immediately gets encrypted
5836 actually with wrong IV (and thus MAC check fails). So, packets
5837 that are in queue should be encrypted when they are sent to
5838 the wire and not when they put to the queue.
5840 However, the problem is that the current system has not been
5841 designed to work that way. Instead, the packet is encrypted
5842 as soon as possible and left to the queue. The queue is then
5843 just purged into wire. There won't be any fixes for this
5844 any time soon. So, the current semantic for packet sending
5847 o If you send packet to remote host and do not force the send
5848 (the packet will be in queue) then all subsequent packets to the
5849 same remote host must also be put to the queue. Only after the
5850 queue has been purged is it safe again to force the packet
5853 o If you send all packets immediately then it safe to send
5854 any of subsequent packets through the queue, however, after
5855 the first packet is put to queue then any subsequent packets
5856 must also be put to the queue.
5858 Follow these rules and everything works fine.
5860 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5862 * Added new function silc_server_remove_clients_by_server to
5863 remove all client entries from ID list when the server connection
5864 is lost. In this case it is also important to invalidate all
5865 client entires as they hold the invalid server entry. This
5866 fixes fatal bug when server has lost connection and will reconnect
5869 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5871 * Made some sanity checks to silc_server_daemonise like to check
5872 whether the requested user and group actually exists.
5874 * Added sanity check to SKE's silc_ske_responder_finish to check
5875 that the public and private key actually is valid.
5877 * Invalidate the client's nickname when receiving Replace ID
5878 packet and the Client ID is being replaced. This means that the
5879 server will query the nickname if someone needs it (client)
5882 * Sort the ID Cache in client library when the ID Cache data
5883 has changed (needs sorting).
5885 * Do not allow for SILC client to create several connections to
5886 several servers. The client does not support windows right now
5887 and generating multiple connections causes weird behaviour.
5889 Irssi-silc client does support windows and can handle several
5890 connections without problems, see: www.irssi.org and SILC plugin.
5892 * Fixed some places where client was added to the IDList. The
5893 rule of thumb is following (in order to get everything right):
5894 If the client is directly connected local client then the
5895 `connection' argument must be set and `router' argument must be
5896 NULL to silc_idlist_add_client function. If the client is not
5897 directly connected client then the `router' argument must
5898 bet set and the `connection' argument must be NULL to the
5899 silc_idlist_add_client function.
5901 * The funtion silc_server_packet_send_local_channel actually did
5902 not check whether the client was locally connected or not. It
5903 does that now. Fixed a bug related to LEAVE command.
5905 * Fixed Remove Channel User payload parsing bug in server's
5906 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
5908 * The server's silc_server_save_channel_key now checks also the
5909 global ID list for the channel as it might not be in the local
5910 list. Fixed a bug related to LEAVE command.
5912 * Is this the end of the [<unknown>] buglet that has been lurking
5913 around for a long time? A little for loop fix in server's
5914 silc_server_command_whois_parse that is used by both IDENTIFY
5915 and WHOIS command. At least, this was a clear bug and a cause
5916 of one type of [<unknown>] buglet.
5918 * WHOIS and IDENTIFY commands call the function
5919 silc_server_command_[whois/identify]_check function even if
5920 we are not router server.
5922 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5924 * Added --with-gmp configuration option. If set the GMP
5925 is always compiled in the SILC source tree. If not set then
5926 it is checked whether the system has the GMP3 installed. If
5927 it has then the GMP won't be compiled (the system's headers
5928 and library is used), if it doesn't have it then the GMP is
5929 compiled in the SILC source tree.
5931 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5933 * Changed RSA private exponent generation to what PKCS #1
5934 suggests. We try to find the smallest possible d by doing
5935 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
5936 not security fix but optimization.
5938 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Added new config entry [Identity] to fork the server and run
5941 it as specific user and group. A patch from Bostik.
5943 * Imported Dotconf configuration library into lib/dotconf.
5944 This will be used to create the SILC configuration files later.
5945 It will appear in the distsribution after this commit.
5947 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5949 * A big code auditing weekend happening. Auditing code for
5950 obvious mistakes, bugs and errors. Also, removing any code
5953 Removed files for being obsolete:
5955 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
5956 inline in the file lib/silcutil/silcbuffer.h)
5958 o lib/silcutil/silcbufutil.c (the header has inline versions)
5960 Changed code to fix possible error conditions:
5962 o The buffer formatting routines now check that the destination
5963 buffer really has enough space to add the data. This applies for
5964 both buffer formatting and unformatting
5965 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
5966 unformatting was changed to accomodate following rules:
5967 XXX_*STRING_ALLOC will allocate space for the data into the pointer
5968 sent to the function while XXX_*STRING will not allocate or copy
5969 the data into the buffer. Instead it sets the pointer from the
5970 buffer into the pointer sent as argument (XXX_*STRING used to
5971 require that the pointer must be allocated already). This change
5972 makes this whole thing a bit more consistent and more optimized
5973 (note that the data returned in the unformatting with XXX_*STRING
5974 must not be freed now). The routines return now -1 on error.
5976 o Tried to find all code that use buffer_format and buffer_unformat
5977 and added return value checking to prevent formatting and
5978 especially unformatting errors and possible subsequent fatal
5981 o Changed ske->x and ske->KEY to mallocated pointers in
5982 lib/silcske/silcske.h. Fixed possible data and memory leak.
5984 o Added return value checking to all *_parse* functions. Fixed
5985 many memory leaks as well.
5987 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
5988 so that buffer overflows would not happen. All code now also
5989 checks the return value as it can fail.
5991 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5993 * Added reconnection support to server if the normal server looses
5994 its connection to the router (for example if router is rebooted).
5995 The server performs normal reconnection strategy implemented
5996 to the server. Affected file silcd/server.c.
5998 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6000 * Added new packet type SILC_PACKET_SET_MODE that is used to
6001 distribute the information about changed modes (for clients,
6002 channels and clients channel modes) to all routers in the
6003 network. Updated the protocol specification accordingly.
6005 Added functions into silcd/packet_send.c and
6006 silcd/packet_receive.c: silc_server_send_set_mode,
6007 silc_server_set_mode.
6009 Added new files silcmode.[ch] into lib/silccore that implements
6010 the encoding and decoding of Set Mode Payload. Added new type
6011 SilcSetModePayload. Moved the definitions of different modes
6012 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6014 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6016 * Oops, a little mistake in server's connection authentication
6017 protocol. The protocol is not ended with FAILURE but with
6018 SUCCESS if the authentication is Ok. :) Affected file is
6021 * Implemented NICK_CHANGE notify handling in server in the file
6022 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6023 the local clients on the channel. After the changing nickname
6024 in router environment snhould work and the [<unknown>] nickname
6025 should appear no more.
6027 The silc_server_replace_id function that receives the Replace ID
6028 payload now sends the NICK_CHANGE notify type also in the file
6029 silcd/packet_receive.c
6031 * Changed WHOIS and IDENTIFY command to support the maximum amount
6032 of arguments defined in protocol specs (3328 arguments). This
6033 fixed a bug that caused problems when there were more than three
6036 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6038 * Added extra parameter, command identifier, to the
6039 silc_client_send_command so that explicit command identifier
6042 Changed that ID list routines uses specific command identifier
6043 when sending WHOIS/IDENTIFY requests to the server so that they
6044 can be identified when the reply comes back.
6046 Affected files lib/silcclient/command.[ch],
6047 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6049 * Added `sender' argument to silc_server_packet_send_to_channel
6050 to indicaet the sender who originally sent the packet to us
6051 that we are now re-sending. Ignored if NULL. Affected file
6052 silcd/packet_send.[ch].
6054 * Added some server statistics support in silcd/server_internal.h
6055 SilcServerStatistics structure and around the server code. Also
6056 send some nice statistics information when client is connecting
6059 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6061 * Fixed channel ID decoding in server's JOIN command reply in
6062 silcd/command_reply.c
6064 * Fixed braodcasting of replace ID payload to not to send it if
6065 we are standalone server in silcd/packet_receive.c.
6067 * Fixed all channel message sending routines to not to send
6068 packets to clients that has router set, since they are routed
6069 separately in the same function earlier. Affects file
6070 silcd/packet_send.c and all channel packet sending functions.
6072 * In USERS reply, res_argv[i] are not allocated, the table
6073 is allocated. Thus changed that free the table, not its
6076 * In server's whois_check and identify_check if the client is
6077 locally connected do not send any WHOIS commands - they are not
6080 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6082 * Fixed some minor bugs in client when sending WHOIS command. The
6083 arguments was in wrong order.
6085 * Removed statis function add_to_channel from server in
6086 silcd/command.c that was previously used with the joining but
6089 * Tested USERS command in router environment successfully with two
6090 routers, two servers and two clients.
6092 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6094 * Reorganized the USERS command and command reply in client library
6095 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6096 When the command is given by user we register a pending command
6097 callback that will reprocess the command after the reply has been
6098 received from the server. When reprocessing the packet we then
6099 display the information. Thus, the USERS information is displayed
6100 now in the command callback instead of in the command reply
6101 callback. The processing of the command is same as previously
6102 when server has sent the command reply in the JOINing process.
6104 * Added to USERS command in silcd/command_reply.c to join the client,
6105 we didn't use to know about, to the channel after we've created
6106 a client entry for it. Also, for clienet we did know already still
6107 check whether it is on the channel or not and add it if not.
6109 * Removed silc_server_command_join_notify as the function and its
6112 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6114 * Changed the client's pending command handling to the same as the
6115 server's pending command handling. It is also now possible to
6116 execute command reply functions from other command reply
6117 function as the function callbacks for commands and command
6118 replies are one and same. The pending commands are not static
6119 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6120 in client connection context. Thus, pending commands are server
6121 connection specific as it is convenient.
6123 Changed the function silc_client_command_pending and
6124 silc_client_command_pending_del and added new function
6125 silc_client_command_pending_check. Removed the
6126 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6129 * Added cmd_ident, current command identifier, to the client
6130 connection context in lib/silcclient/client.h to keep track on
6131 command identifiers used in command sending. Client's command reply
6132 function handling now supports the mandatory command identifiers.
6134 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6135 funtions in client to fully support pending command callbacks.
6137 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6138 as one of the arguments to the application in the command reply
6141 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6142 before first releasing SILC but came back. Now it is removed again
6143 and should come back nomore. The FORWARDED flag was used only
6144 by the JOINing procedure by forwarding the command packet to router.
6145 Now, the JOINing procedure has been changed to more generic (due
6146 to various router environment issues) and FORWARDED is not needed
6147 anymore for anything. The protocol specification is yet to be
6150 Now, removed silc_server_packet_forward from server and the flag
6151 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6153 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6155 * Renamed NAMES command to USERS command. The NAMES was named that
6156 due to historical reasons. Now it is renamed. Also, rewrote
6157 parts of the USERS command. The nickname list is not sent anymore
6158 by the server. Only Client ID and mode lists are sent in the USERS
6159 command. Changed this also to the protocol specification.
6161 The client now resolves the names and stuff after it receives
6162 the USERS list from the server when joining to the channel.
6164 * WHOIS and IDENTIFY commands has been changed to support multiple
6165 Client ID's per command. One can now search for multiple users
6166 in the network by sending only one WHOIS or IDENTIFY command.
6167 Changed the code and the protocol specifications.
6169 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6170 uses silc_server_command_whois_parse to parse the request. */
6172 * If normal server, do not parse the WHOIS and IDENTIFY requests
6173 before sending it to the router. Saves some time.
6175 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6177 * Fixed JOIN command on client library. Wrong number of arguments
6178 used to crash the client.
6180 * Added silc_server_channel_has_global function to check whether
6181 channel has global users or not.
6183 * Added silc_server_channel_has_local function to check whether channel
6184 has locally connected clients on the channel.
6186 * The silc_server_remove_from_one_channel now checks whether the
6187 channel has global users or not after given client was removed from
6188 the channel. It also checks whether the channel has local clients
6189 on the channel anymore. If it does not have then the channel entry
6190 is removed as it is not needed anymore.
6192 * The silc_server_notify now checks on JOIN notify whether the joining
6193 client is one of locally connected or global. If it is global then
6194 the channel has now global users on the channel and that is marked
6195 to the channel entry. Also, it now saves the global client to
6196 global list who is joining and JOINs it to the channel. This is
6197 for normal server, that is.
6199 Changed silc_server_send_notify_on_channel,
6200 silc_server_packet_relay_to_channel and
6201 silc_server_packet_send_to_channel check if we are normal server
6202 and client has router set (ie. global client) do not send the
6203 message to that client, as it is already routed to our router.
6205 * Implemented LEAVE notify type handling in silc_server_notify
6208 * Tested LEAVE command in router environment successfully. Tested
6209 with two routers, two servers and two clients.
6213 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6215 * Implemented SIGNOFF notify type handling in silc_server_notify
6218 * silc_server_remove_id now removes the client entry from all channels
6219 it has joined and thusly sends SIGNOFF notify type.
6221 * Rewrote the NAMES list generation in server by removing two excess
6222 loops. The lists are created now inside one loop.
6224 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6226 * silc_server_remove_channel_user checks now also global list
6227 for channel and client.
6229 * silc_server_new_channel_user checks now both local and global
6230 list for channel and client. Fixed a bug in client id decoding.
6231 Used to decode wrong buffer.
6233 * silc_server_channel_message checks now both local and global
6234 list for channel entry.
6236 * Tested channel joining (hence JOIN) in router environment
6237 successfully. Tested with two routers, two servers and two
6240 * Tested channel message sending in router environment successfully.
6242 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6244 * Added silc_server_save_channel_key into server.[ch] to save the
6245 received channel key in Channel Key payload processing. It is
6246 also used in JOIN command reply handling.
6248 Equivalent function silc_client_save_channel_key added into
6249 client.[ch] into client library.
6251 * Changed JOIN command reply to send information whether the channel
6252 was created or not (is existing already) and the channel key
6253 payload. Changed protocol specs accordingly.
6255 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6256 the request was sent by ID and not by nickname. Crashed on
6259 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6261 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6262 now correctly save the received data.
6264 * silc_server_free_sock_user_data now notifies routers in the
6265 network about entities leaving the network.
6267 At the same time implemented functions silc_server_remove_id
6268 and silc_server_send_remove_id to receive and send REMOVE_ID
6269 packets. The packet is used to notify routers in the network
6270 about leaving entities. The ID removed will become invalid in
6273 * Added function silc_idlist_del_server into server. Removes and
6274 free's server entry from ID list.
6276 * silc_server_private_message function now checks, if we are router,
6277 that the destination ID really is valid ID, naturally.
6279 * In router when NEW_ID packet is received (for new client) the
6280 hash of the Client ID is saved in the ID Cache but the
6281 client->nickname is set to NULL, instead of putting the hash
6284 IDENTIFY command now also checks that client->nickname must be
6285 valid. If it is not if will request the data from the server who
6286 owns the client. Added new function
6287 silc_server_command_identify_check.
6289 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6290 to set the command to already allocated Command Payload.
6292 * Tested private message sending in router environment with two
6293 routers, two servers and two clients. Fixed minor bugs and now
6296 * Fixed segfault from client's NAMES command. Used to crash if
6299 * Forwarded packets must not be routed even if it is not destined
6300 to the receiver. Changed server code comply with this.
6302 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6304 * Added `require_reverse_mapping' boolean value to ServerParams
6305 structure. If TRUE (not default) the server will require that
6306 the connecting host has fully qualified domain name.
6308 If the reverse mapping is not required and hostname could not be
6309 found the IP address is used as hostname.
6311 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6313 * Implemented version string checking to both client and server.
6314 The check is incomplete currently due to the abnormal version
6315 strings used in development version of SILC.
6317 * Changed all command functions in server to use the new
6320 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6322 * Changed char *data to unsigned char *data in ID Cache system to
6323 support binary data as ID Cache data. Changed code to support
6324 binary data in lib/silccore/idcache.c.
6326 * Renamed silc_server_packet_relay_command_reply to
6327 silc_server_command_reply as it is normal packet receiving
6328 function. Rewrote the function to accept command replys for
6329 servers and not only for clients.
6331 * Mark remote router always as registered server if we are connecting
6332 to it. Otherwise, commands sent by the router to us are ignored.
6334 * All ID List find routines now returns the ID Cache Entry pointer
6335 as well if requested.
6337 * WHOIS command works now in router environment, tested with two
6338 routers, two servers and two clients.
6340 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6341 in router environment (as it is almost equivalent to WHOIS) but
6342 hasn't been tested thoroughly. Added new functions:
6344 silc_server_command_identify_parse
6345 silc_server_command_identify_send_reply
6346 silc_server_command_identify_from_client
6347 silc_server_command_identify_from_server
6349 * Disabled route cache adding because adding two different ID's with
6350 same IP replaces the old cache entry thus giving wrong route.
6351 The entry->router->connection is always the fastest route anyway
6352 so route cache may not be needed. Of course, new routes maybe
6353 established after receiving the ID when the entry->router->connection
6354 might not be anymore the most optimal.
6356 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6358 * Add route cache for received ID for fast routing.
6360 * Added silc_server_packet_route to route received packet on router
6361 that is not destined to us.
6363 * Renamed silc_server_get_route to silc_server_route_get.
6365 * Added id_string and id_string_len fields into SilcServer to
6366 include encoded ServerID for fast comparing without excess
6367 encoding of the ID's.
6369 * Cleaned up WHOIS command on server side. Added following static
6372 silc_server_command_whois_parse
6373 silc_server_command_whois_check
6374 silc_server_command_whois_send_reply
6375 silc_server_command_whois_from_client
6376 silc_server_command_whois_from_server
6378 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6379 arguments in command replies. All command functions should be
6380 updated to use this macro.
6382 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6384 * Minor typo fixes on command reply handling on server.
6386 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6388 * Added silc_server_command_add_to_channel internal routine to add
6389 the client to the channel after router has created the channel and
6390 sent command reply to the server.
6392 * Added generic silc_server_send_command to send any command from
6395 * Use static buffer with ID rendering instead of duplicating data.
6397 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6399 * Fixed a channel user mode bug when joining to a channel server gave
6400 everybody channel founder rights, oops.
6402 * We mark ourselves as the router of the incoming server connection
6403 if we are router ourselves. This way we can check in some packet
6404 sending functions whether it is locally connected server. For
6405 incoming router connections we put NULL.
6407 * For router sending packets locally means now always sending the
6408 packet cell wide; to local clients and local servers. For normal
6409 server sending packet locally means sending it to only local
6412 * Fixed the JOIN command to really work in router environment. If the
6413 channel is created it is always created by the router. Router is
6414 also responsible of making the initial joining to the channel,
6415 sending JOIN notify to the sending server and distributing
6416 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6417 does not exist server doesn't do anything else but forward the
6418 command to the router which performs everything.
6420 * Added silc_server_send_channel_key function to send the Channel Key
6423 * Added silc_server_create_channel_key to create new channel key. The
6424 channel key is now re-generated everytime someone joins or leaves
6425 a channel, as protocol dictates. Note: channel->key_len is the
6428 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6430 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6431 packet_receive.[ch] to separate packet sending and receiving
6432 routines. The server.[ch] now includes everything else including
6433 actual packet processing (writing and reading data) and other
6436 Renamed silc_server_private_message_send_internal to
6437 silc_server_send_private_message. The routine is still though
6438 used only to relay private messages as server does not send
6439 private messages itself.
6441 Renamed silc_server_new_channel to silc_server_create_new_channel
6442 and added new function sicl_server_new_channel that handles the
6443 incoming New Channel packet. Added also new sending function
6444 silc_server_send_new_channel to send New Channel Payload.
6446 * Added new function silc_server_notify to process incoming notify
6447 packet to the server/router. Server may then relay the notify
6448 to clients if needed.
6450 * Added new function silc_server_new_channel_user to process incoming
6451 New Channel User packet. Router will redistribute the packet and
6452 send JOIN notify to its local clients and locally connected servers
6453 if needed. Normal server will send JOIN notify to its local client
6454 on same channel when received this packet. Added also corresponding
6455 sending function silc_server_send_new_channel_user to sent the
6458 * Added boolean route argument to send_notif_to_channel and
6459 packet_send_to_channel functions to attempt to route the packet
6460 if it is TRUE and send only locally if it is FALSE.
6462 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6464 * silc_server_replace_id now broadcasts the received replace ID
6465 packet if it is not broadcast packet already. The router must
6466 broadcast to inform other routers about changed ID.
6468 * Added backpointer to server's router into SilcServer context in
6469 silcd/server_internal.h.
6471 * Fixed silc_server_packet_broadcast to send correct broadcast
6474 * The channel key is now distributed to the local client as soon
6475 as it is received from the router (in router environment) so that
6476 no other packet may be sent for the channel until client has
6479 * silc_server_remove_channel_user now broadcasts the received
6480 Remove Channel User packet if it is not broadcast packet already.
6481 The router must broadcast to inform other routers about removed
6484 * Added users field into SilcPacketContext that is a reference count
6485 of the context. One can increase the reference count by calling
6486 silc_packet_context_dup which is now changed to just increase the
6487 reference count instead of duplicating the data. The reference
6488 count is decresed by calling silc_packet_context_free that will
6489 free the data after the reference count hits zero.
6491 For now on the packet context and everything allocated into it
6492 (including the raw packet from network) must be freed by calling
6493 the new silc_packet_context_free function. Added also new function
6494 silc_packet_context_alloc that must be used now to allocate the
6495 context. This also means that if a routine is asynchronous from
6496 silc_[client/server]_packet_parse_type the packet context must
6497 be duplicated by calling silc_packet_context_dup. Otherwise it
6498 gets free'd after silc_[client/server]_packet_parse_type returns.
6499 Also, one must remember that if packet is duplicated then its
6500 reference count must be decresed by calling the free function as
6501 many times as it was duplicated.
6503 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6504 from both client and server.
6506 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6508 * Made joining to a channel working in router environment.
6510 * Cleaned up JOIN command on server side and create function
6511 silc_server_command_join_channel internal routine to make the
6514 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6516 * Changed silc_command_pending list to SilcDList. Also, added
6517 `ident' field to SilcServerCommandPending structure to identify
6518 the reply and to call correct callback.
6520 Added silc_server_command_pending_check function to replace the
6521 corresnponding macro. The silc_command_pending list is not
6524 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6525 to set identifier to previously allocated Command Payload. It
6526 is used to set identifier for command when resending Command
6529 * Added silc_command_payload_encode_payload to encode Command
6530 Payload buffer from SilcCommandPayload structure.
6532 * Added silc_argument_payload_encode_payload to encode Argument
6533 payload buffer from SilcArgumentPayload structure.
6535 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6537 * Changed WHOIS command to support router connection on server side.
6538 The whois request is always sent to router unless the server is
6539 standalone server. After server has received the reply from the
6540 router will it send the reply to the client.
6542 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6543 broadcast received broadcast packet. The function is used only
6544 by router. The broadcast packet is always sent to the router's
6547 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6548 render given ID to printable string, for log files for example.
6550 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6552 * Made basic router to router connections working. At least they
6553 can now connect to each other but nothing really works the way
6554 they are supposed - yet.
6556 * Added new initiator token to RouterConnection configuration
6557 file in silcd/serverconfig.[ch]. It is used to tell whether we
6558 are the initiator to the remote router or whether we'll expect
6559 the other end to connect.
6561 * Moved registering of listener task to silc_server_init, hence
6562 the server starts listenning as soon as it is run, even if it
6563 does not have connections to other routers. Let's see how well
6566 * Changed default connection retry timeouts for more suitable in
6569 * Removed cipher and such arguments from silc_idlist_add_client
6570 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6571 Added new function silc_idlist_add_data to add the keys and stuff
6574 * Added SilcIDListData structure and added it to SilcClientEntry
6575 and SilcServerEntry as their first field in the structure. This
6576 way we can explicitly cast the ID entries to the SilcIDListData
6577 structure and get common data for the entries. In past, we had
6578 to first check what type of connection it is and then cast it to
6579 correct ID entry type. Now, we can directly cast the opaque
6580 pointer to the SilcIDListData (no matter what ID entry it actually
6581 is) and get the data needed.
6583 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6585 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6586 in some circumstances even if threre were timeout tasks, though not
6587 IO tasks, but tasks anyway. Now fixed.
6589 * Defined SilcServerConnection structure to hold connection specific
6590 stuff about directly connected servers and routers. The definition
6591 is currently in silcd/server_internal.h. I thought about having
6592 a bit more important role fro this struct but for now it is used
6593 only when connecting to other server (or router actually).
6595 * Added connecting retry support in server when connecting to
6596 router(s). The retry feature implement exponential backoff
6597 algorithm. Also, added SilcServerParams structure to hold default
6598 parameters for server. For now, it include these retry settings
6599 and are hard coded. After server is moded to be as Silc Server
6600 Library this structure will be more important.
6602 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6604 * Changed client librarys channel->clients table to SilcList and
6605 changed code accordingly.
6607 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6609 * Changed client's channel table to SilcList and changed code
6610 accordingly. Also changed SilcChannelClientEntry to include back-
6611 pointer to the channel so that client entry can use that structure
6612 as list as well and we have fast cross-reference to the channel.
6613 This change dramatically decreased the complexity of channel
6614 handling with client entry and vice versa (removed one extra
6615 loop when searching for channel entry from many functions).
6617 * Changed server->sim from table to SilcDList and changed code
6620 * NAMES command can now be used from user interface. It will show
6621 the user list on the channel, neatly.
6623 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
6624 Code now saves realname of the user if it becomes available.
6626 * Renamed configure.in to configure.in.pre and made ./prepare
6627 script to automatically add correct version string to
6628 configure.in which it creates from configure.in.pre.
6630 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6632 * NAMES command reply now shows users mode with the nickname when
6635 * Moved silc_client_ch[u]mode[_char] functions from
6636 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
6637 place sucks, they are utility functions and should be in some
6640 * Fixed some unsigned int's to unsigned short's. Patch by cras.
6642 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
6645 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6649 * Added TRQ (efficient deque and list library) into lib/trq. This is
6650 a very good list library that is currently used in the SILC. Defined
6651 SilcList API over the library because I didn't like the API very
6652 much. See lib/trq/silclist.h for the API and examples of how to
6653 use the API. Fixed various places in the code to use the new
6654 SilcList API. The SilcList is meant for lists that has a structure
6655 already defined as a list. It is not suitable to add just some
6656 context to the list (in TRQ, the context is the list actually).
6658 So, I defined SilcDList that can be used for the purpose where
6659 predefined list structure does not exit. This can be used as
6660 such list. Now some context just can be added to the SilcDList.
6661 Currently this list is not used in the SILC just yet, though there
6662 are a lot places where this can replace dynamically allocated
6663 tables and I will fix these places, later, to use SilcDList.
6664 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
6665 and use TRQ internally).
6667 Also fixed some annoying warning messages that the original TRQ
6668 code generated. Also minor changes to TRQ's Makefile.in.
6670 * Added support for querying by Client ID to both WHOIS and
6671 IDENTIFY commands into server, as required by the protocol.
6673 * Removed method function pointers from SilcBuffer structure. They
6674 weren't used to anything and just increased the context size for
6675 no good reason. This change also made silc_buffer_alloc and
6676 silc_buffer_free functions inline functions.
6678 * Disabled command flooding detection support until it's fixed so
6679 that it accepts commands in but does not execute them more than once
6682 * Added silc_net_localhost(), to return local hostname, into
6683 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
6684 that must be initialized before calling silc_client_init.
6686 * Added new function: silc_server_send_notify_on_channels to send
6687 notify messages to all channels client has joined. It is assured
6688 that the message is sent only once per client.
6690 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
6691 lib/silcutil/silcutil.[ch] as silc_format function. The new
6692 function is generic and is used by server as well, not only by
6693 the logging routines.
6695 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
6696 the provided version string was not acceptable. Added new function:
6697 silc_ske_check_version into lib/silcske/silcske.h. The function
6698 must be implemented by the application (client or server) and it
6699 does not reside in the SKE library. The function checks the version
6700 string remote end sent.
6702 * Added back pointers (to opaque context and to SilcSocketConnection)
6703 into SilcPacketContext structure into lib/silccore/silcpacket.h.
6705 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
6706 duplicate packet context structure.
6708 * Changed `notify' client operation to send same arguments as client
6709 receives from server except for ID's. ID's are mapped to correct
6710 ID entry and that is returned. Also, if channel entry is not sent
6711 by server but the notify is for channel the channel entry is sent
6712 to application (otherwise application doesn't know that it is for
6713 channel (library gets it from packet's Destination ID)).
6715 * Added silc_client_remove_from_channels into client library to
6716 remove a client from all channels it has joined to. Used when
6717 received SIGNOFF notify from server. Added also new function
6718 silc_client_replace_from_channels to replace old ID entry with
6719 new ID entry on all channels. Used when received NICK_CHANGE
6722 * Fixed ID Cache list handling in silc_idlist_get_client in
6723 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
6724 to get (or query) client by ID.
6726 * Updated TODO list.
6728 * Added connection authentication status message defined by the
6729 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
6730 support for these into the code in client and server side.
6732 * Added generic function silc_client_send_command to send any command
6733 with variable argument list. Application should use this function
6734 to send commands if the command functions provided by the library
6735 does not suite for the application's user interface needs.
6737 * Added new `failure' client operation. Application is notified about
6738 received failure packet if client is executing a protocol. In this
6739 case the protocol's execution has failed.
6741 * Added SKE's end notify to send the SKE_SUCCESS notify message that
6742 is required by the protocol.
6744 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
6745 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
6748 * Added status flag to SilcSKE object to indicate realtime status
6749 of the SKE protocol.
6751 * Application receives now exactly same command reply arguments as
6752 the library receives from server. However, if ID is received the
6753 corresponding ID entry is returned to the application (eg. Client
6754 ID is mapped to correct SilcClientEntry entry and that is returned).
6755 Changed command_reply client operation due to this change.
6757 * Changed all ID's in commands and in command replys as ID Payloads.
6758 Change affected both client and server side codes.
6760 All ID's sent in SILC network (with execption of ID's in SILC
6761 Packet header) are sent in ID Payload to support variable length
6764 * Server now notifies nick changes and notifies all clients on
6765 the channels about the new nickname (about the new Client ID,
6768 * Implemented CMODE command to change channel modes. Supports all
6769 channel modes defined by the protocol specs except ban and invite
6770 lists. (Also, private channel key mode is supported but support for
6771 setting private channel key in client is missing, thus, this mode
6772 has no effect on client side (except that server requires that the
6773 client uses private channel key and normal channel traffic does not
6776 Also, invite mode works per se, but INVITE command does not work
6777 yet correctly, so you can set channel as invite only channel but
6778 inviting clients to the channel does not work (it is yet to be
6779 thought what's the best way to do it).
6781 * Added new command SILC_COMMAND_CUMODE to change user mode on the
6782 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
6783 Implemented CUMODE command to change user's mode on the channel.
6784 Supports all modes defined by the protocol specs.
6786 * Added NAMES command reply to return users modes on the channel.
6788 * Removed unnecessary and slow ciphers from lib/silccrypt.
6790 * Set SO_KEEPALIVE option to connection sockets by default.
6792 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
6794 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
6795 redefined the Notify Payload into protocol specs.
6797 * Added silc_id_payload_parse_id to get ID directly from raw
6800 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6802 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
6803 accept searching by Client ID as well.
6805 * Added support for LEAVE and SIGNOFF notify types in client library.
6807 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
6808 to parse ID Payload from raw data.
6810 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6812 * Added flags parameter into silc_ske_assemble_security_properties
6813 function in lib/silcske/silcske.[ch].
6815 * Changed notify client operation to fit better for notify messages
6816 sent by server. The notify payload received from server is now
6817 passed to the application (after parsing it to SilcNotifyPayload).
6818 It is application's responsibility to retrieve the arguments
6819 from the payload and show the message the way it wants. The message
6820 sent by server is implementation specific.
6822 * Changed public keys to comply with the protocol specification.
6823 Old public keys are not supported anymore and are not compatible.
6825 * Removed nickname from Channel Payload as the latest draft removed
6826 it. The client must resolve the nickname from the NAMES command
6827 reply received when it joined the channel.
6829 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
6831 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6833 * Fixed some errors in protocol specification drafts.
6835 * Created lib/silccore/silcnotify.c to implement Notify Payload
6836 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
6837 generic payloads described by protocol specifications. The file
6838 includes implementations for ID Payload and Argument Payload.
6840 * Changed Command Payload implementation to use the new Argument
6841 Payload. Changed command_xxxx_payload to command_payload_xxxx
6842 to comply with SILC coding conventions.
6844 * Added suppport for Argument Payload handling in Notify Payload
6845 implementation as protocol requires it. Added the new support
6846 into server and client lib as well.
6848 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6850 * Added support for multiple nicknames on same channel. [n] is
6851 added locally to the nickname if there are more than one same
6852 nicknames on the channel.
6854 * Server now sends all nicknames that matched WHOIS request.
6855 Client also shows the list received from server.
6857 * Added TOPIC command to client side. User can now set and show
6858 current topic on channel.
6860 * Added MOTD command to client and server. Also, server sends the
6861 motd when client connects to the server.
6863 * Changed version strings to comply ISO 8601.
6865 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6867 * Fixed protocol error handling in client library. It should now
6868 cope even if the SKE fails for some reason.
6870 * Made new protocol specification drafts for submitting to IETF.
6872 * Implemented TOPIC command to server in silcd/command.c.
6874 * Added two new notify types into lib/silccore/silcnotify.h:
6875 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
6876 notify nickname change and topic setting/change on a channel.
6878 * API change of command_reply operation in client library. The
6879 application gets now the status type received from server as well.
6881 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6883 * Removed the function just added to lib/silcutil/silcschedule.[ch].
6885 * Cras fixed and optimized the packet handling even further and
6886 it should work now. Minor change to the prototype of function
6887 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
6889 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6891 * Added new function into lib/silcutil/silcschedule.[ch]:
6892 silc_schedule_with_fd to select() a specified fd. The function
6893 returns after timeout expires or data arrives or goes. The
6894 function is used by packet routines to wait that all data is
6895 received from network.
6897 * Fixed data reading from network in lib/silccore/silcpacket.c.
6898 The code now assures that all data is read from the fd and then
6899 continues packet processing. This was a bug fix since the code
6900 used to drop some data in some circumstances.
6902 * Added new function into lib/silcclient/client.[ch]:
6903 silc_client_start_key_exchange to start key exchange after
6904 connection has been established to server. The code internally
6905 now uses this funtion but its main purpose was to provide it
6906 for applications that perform their own connecting. After
6907 application has created a connection it merely calls this
6908 function to start the key exchange between client and server.
6909 The library takes care of everything else after that.
6911 Updated also lib/silcclient/README to explain the usage of
6914 * Do not send to application information that connection has
6915 been established. Application gets notified it by connect
6918 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6920 * Applied cras's patch to add silc_schedule_one function. The
6921 function runs scheduler once and returns.
6923 * Fixed the scheduler after cras messed it up. The timeout
6924 handling works now as it's supposed to work.
6926 * Added into lib/silccore/ silcnotify.h to include notify
6927 message types support. Changed silc_server_send_notify*
6928 functions, in server.[ch], to support those new notify types.
6929 Added the support for the notify types into client library,
6930 as well. Added new notify client operation into ops.h in
6933 * Changed silc_server_packet_send_to_channel to send normal
6934 packets instead of just channel message packets. The function
6935 is now used to send the notify packets to channels. It is not
6936 used to send channel message packets anymore, as server never
6939 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
6940 va_arg()s as it seems to require it nowadays. I guess, if SILC
6941 is compiled with older va_arg() the new code should work anyway.
6943 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6945 * Splitted core library. Core library (lib/silccore) includes
6946 now only SILC protocol specific core (and common) components.
6947 Created new utility library (lib/silcutil) that includes more
6948 generic purpose stuff. The stuff for util library was taken
6949 from the old core library. This was minor and easy split.
6951 * Created SILC Client Library (lib/silcclient) that includes
6952 implementation of the SILC client without user interface. This
6953 was major move from silc/ directory. The code has been changed
6954 so that it is transparent towards the user interface. The
6955 silc/ directory includes now the same user interface as before
6956 and it uses the new client library. Read lib/silcclient/README.
6957 Basicly, the client library performs everything else related
6958 to SILC except user interface handling. Also, configuration
6959 files are considered to be part of user interface and library
6960 does not handle them.
6962 This change also changed a lot of structures, function naming etc.
6963 Most important change was that SilcClientWindow object was
6964 renamed to SilcClientConnection in the client library. Created
6965 also new file lib/silcclient/ops.h. Also added new files
6966 silc/local_command.[ch] and silc/client_ops.[ch].
6968 All these changes were made to make it easier for user interface
6969 designers to create what ever user interface for the SILC client
6972 It is also expected that the server will be moved to lib
6973 directory as well and SILC Server Library will be created;
6974 sometimes in the future.
6976 * Removed Local commands from lib/silccore/silccommand.h as
6977 they are application specific and new client library does not
6978 handle any of those anymore.
6980 * Several functions moved to lib/silcutil/silcutilc.[ch] from
6981 old client implementation in silc/.
6983 * Added support for callback functions in SILC_LOG_* macros.
6984 Application can now set its own callbacks that will be called
6985 instead of using the default functions that will always print
6986 the debug messages to stderr (or stdout). Also, debugging can
6987 now be disabled by setting silc_debug to FALSE and re-enabled by
6988 setting it to TRUE. Note, that logging will still work even
6989 if debugging is disabled.
6991 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
6992 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
6993 silc_log_reset_debug_callbacks.
6995 * To enable debugging in silc client one must give now -d
6996 option on command line.
6998 * Changed silc_schedule_init to automatically allocate task queues
6999 if they are not allocated before calling it.
7001 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7003 * Added GMP 3.1 into math library.
7005 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7007 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7008 a channel in SILC network. The packet is used by servers and
7009 routers to notify other routers that user has left a channel.
7010 This little feature was missing until now. Added the feature
7011 to protocol specification as well.
7013 Added functions: silc_server_send_remove_channel_user and
7014 silc_server_remove_channel_user into server.[ch].
7016 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7017 lib/silccore/silcpacket.h. However, they are not implemented
7020 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7022 * Fixed joining to a channel and sending channel messages
7023 between server and router. The channel message sending should
7024 now work inside a cell.
7026 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7028 * Fixed the private message sending between server and router.
7029 The private message sending should now work inside a cell.
7031 * Added silc_server_replace_id into server.[ch] to replace
7032 existing ID in the SILC network.
7034 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7035 and silc_idlist_replace_server_id into idlist.[ch] in server.
7037 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7039 * Fixed the server to server connections. Server can again now
7040 connect to router. Router to router connections probably does
7043 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7045 * Added dynamic protocol registering support. Now protocols can
7046 registered and unregistered on the fly. Patch by cras.
7048 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7050 * Added lib/contrib directory to hold routines that some platforms
7051 don't have but are needed by SILC.
7053 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7054 into lin/contrib to provide getopt() and getopt_long() for
7055 those who don't have it.
7057 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7059 * Added AWAY command to client. When away message is set and
7060 client receives a private message packet the client automatically
7061 replies to the sender with the away message.
7063 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7064 bug seemed to be the cause of recent problems when compiling
7067 * Added version detection support to SKE protocol specification
7068 and added the new changes to the SKE implementation as well.
7069 There were other minor changes in the SKE protocol as well.
7071 Many changes in lib/silcske/silcske.[ch] and in
7072 lib/silcske/payload.[ch].
7074 * Added ^U functionality, clear input line. Patch from cras.
7076 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7078 * Mainly small bugfixes on core library. Fixed some debugging
7079 logging and buffer overflow in silclog.c.
7081 * Updated config.sub and config.guess on the distribution tree.
7083 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7085 * Added command lagging support in server. Client may execute
7086 commands now only once in two seconds.
7088 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7090 * Optimized packet reception. MAC computation and checking is now
7091 also more optimized. A lot previously duplicated code is now
7092 used as generic by both client and server.
7094 * Fixed key pair generation in clientutil.c
7096 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7098 * Added into lib/silccore/silcbufutil.[ch] new function;
7099 silc_buffer_realloc.
7101 * Moved generic packet sending/encryption functions to
7102 lib/silccore/silcpacket.[ch] from client and server. Some
7103 rewriting of the functions.
7105 * Moved all generic packet reception/decryption functions to
7106 lib/silccore/silcpacket.[ch] from client and server. The
7107 packet processing is now much cleaner in both client and server.
7108 These were major changes in both client and server.
7110 * Created many common functions in server to do packet sending.
7111 Previously code were duplicated a lot, this has been removed
7114 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7116 * Rewrote major parts of the ID cache system. Don't know
7117 whether it is better now or not but at least the API is more
7120 * Major rewrite on ID cache stuff on client because of the ID
7121 cache API changes. Added idlist.c to client.
7123 * Also major rewrite on ID cache stuff on server as well.
7124 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7125 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7126 in hand, instead they are all put into the ID cache system now.
7127 All server_idlist_* routines uses ID cache now instead of
7128 traversing its own lists (those lists does not exist anymore).
7129 SilcIDList though still exists. Also, SilcXXXEntry's are
7132 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7134 * Finally made the SKE implementation compliant to the protocol
7135 specification. All mp integers are now binary encoded as
7136 opposed being HEX encoded.
7138 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7141 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7142 functions: silc_[encode/decode]_pem. Also added function
7143 silc_encode_pem_file to PEM encode with newlines ('\n') for
7146 * SILC public keys are now encoded either PEM or binary. Same
7147 option is for private keys as well. By default private keys
7148 are binary encoded and public keys PEM encoded. Silly HEX
7149 encoding were removed.
7151 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7152 function to create fingerprints.
7154 * Fixed a bug in SHA1; does not change the original data anymore.
7156 * Partly implemented INFO command on client and server side.
7157 Fixed CLEAR command. Changes to SERVER command; show current
7158 server(s) when giving command without arguments. Added
7159 VERSION command to client.
7161 * Added check to server that unregistered connections cannot
7162 execute commands (unless it is specificly allowed).
7164 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7166 * Fixed screen refresh.
7168 * Fixed channel joining bug from client. On some circumstances
7169 client tried to join to a channel it had already joined.
7171 * Added public key verification process into client's protocol.c.
7172 The client now verifies the public key from user and saves
7173 it into ~./silc/serverkeys/ directory.
7175 Added into: clientutil.[ch]: silc_client_verify_server_key.
7177 * Changed SKE protocol's silc_ske_initiator_finish function
7178 to accept callback function that verifies the received public
7179 key. Removed old silc_ske_verify_public_key function.
7181 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7183 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7184 silc_pkcs_private_key[_data]_set.
7186 * Made the password and public authentication more cleaner in
7187 server's protocol.c.
7189 * Removed historic and obsolete protocol `channel_auth' from
7190 both client and server.
7192 * Removed wrong way of sending command status messages from
7193 server to client in server's command.c. The old way violated
7194 protocol specification.
7196 Changes to silccore/silccommand.[ch]: removed
7197 silc_command_encode_status_payload -> not needed anymore,
7198 changed silc_command_encode_payload_va to accept extra
7199 argument on variable argument list. The argument type must
7200 now be provided to the function. Also, added new function:
7201 silc_command_encode_reply_payload_va which is same as
7202 normal command_encode_payload_va except command status type
7203 is provided as extra argument.
7205 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7207 * Added ~./silc directory handling. The directory includes the
7208 public and private keys for the client.
7210 Added silc_client_check_silc_dir, silc_client_create_identifier
7211 and silc_client_load_keys.
7213 * Implemented SILC protocol compliant public key. Added public
7214 and private key saving to and loading from files.
7216 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7217 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7218 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7219 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7220 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7222 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7223 silc_pkcs_load_[public/private]_key.
7225 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7227 * Added silc_server_get_route (route.[ch]) to get connection
7228 data for the fastest route for given ID.
7230 * Implemented INVITE command on client and server. The command
7231 were re-defined in the SILC Protocol Specification and the
7232 implementation now complies with the specification.
7234 * Implemented PING command on client and server.
7236 * Implemented NAMES command on client and server. The server side
7237 supports currently only normal server not router server yet.
7238 Some changes to NAMES definition in SILC protocol specification.
7240 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7242 * Implemented LEAVE command on client and server.
7244 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7245 again. This change was made to the protocol as well. Server
7246 should not violate the protocol specification anymore.
7248 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7250 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7251 was tested. SOCKS4 was not but should work anyway.
