332 It is not able to send requested attributes in WHOIS command,
333 and also receive and process requested attributes. Added
334 silc_client_attribute_[add|del] and silc_client_attributes_get
335 functions. Added also `ignore_requested_attributes' to the
336 SilcClientParams to not use attributes in client. Affected
337 files are lib/silcclient/command.c, client_attrs.[ch],
338 silcclient.h, client_internal and client.[ch].

358 * Changed the silc_attribute_payload_encode to support list
359 of attributes (function may be called several times to add
360 a new attribute). Removed the silc_attribute_payload_encode_list
361 function. The encoding function now also automatically encodes
362 the data, so the caller does not need to do that. Affected
363 files lib/silccore/silcattrs.[ch].
365 * Added support for replying on behalf of the user to the
366 Requested Attributes in WHOIS command in the server. Affected
367 file silcd/server_query.c.

416 * Resumed client packet handling from server put the resumed
417 client on wrong list on router and caused the client not
418 be present on the network anymore. Now fixed to put the
419 client to correct list. Affected file silcd/packet_receive.c.
421 Wed Sep 18 15:13:48 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>

434 Mon Sep 16 12:02:54 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
436 * Added 'app_context' to silc_schedule_init. It is an
437 application specific context that is delivered to application
438 in task callback functions. Affected files are
439 lib/silcutil/silcutil.[ch].
441 * The hb_context in SilcSocketConnection is not freed
442 automatically anymore (application must free it). Freeing
443 it automatic is inconsistent. Affected files are
444 lib/silcutil/silcsockconn.[ch].
446 Sun Sep 15 22:16:19 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

468 Patch provided by Ville Räsänen <ville.rasanen@iki.fi>.
470 Wed Sep 11 09:22:00 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
472 * Assure that channel key is set before sending it. May
473 crash server otherwise. Affected file silcd/packet_send.c.
475 Tue Sep 10 09:50:08 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
477 * Assure that endless loop cannot happen with detached client
478 resolving on normal server. Added idlist status
479 SILC_IDLIST_STATUS_RESUME_RES. Affected files are
480 silcd/idlist.h and silcd/packet_receive.c.
482 Mon Sep 9 12:18:18 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
484 * Incoming file transfer request cannot use same session as
485 the sending session. This can happen when sending file to
486 yourself. Crashed the client on quit. Affected file
487 lib/silcclient/client_ftp.c. Bug #24.
489 Sun Sep 8 18:39:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
491 * Implemented the draft-riikonen-precense-attrs draft and
492 the Attribute Payload into the lib/silccore/silcattrs.[ch].
494 Sun Sep 8 13:13:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
496 * Distribute the SERVER_SIGNOFF notify also to local backup
497 routers from the primary router. The backup router may not
498 have the signing of local server directly connected and need
499 to know about the signoff. Affected file silcd/server_util.c.
501 * Use the primary router as the origin of the locally connected
502 server when it is disconnecting from the backup router since
503 that's where it really is coming from. Now the clients from
504 the disconnecting server are removed correctly and "shadow"
505 clients are not left to the backup router. Affected file
508 Sat Sep 7 22:26:50 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
510 * If normal server is standalone and found existing but disabled
511 channel, do not re-create the channel since it creates
512 duplicate same channels. Affected file silcd/server.c.
514 * Added anonymous client connections support to server. New
515 "anonymous" configuration option to ConnectionParams section
516 added. If set to true, the username and hostname information
517 of the client will be scrambled and anonymous user mode is
518 set automatically to the user. Affected files are
519 silcd/serverconfig.[ch], silcd/packet_receive.c and server.c.
521 Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
523 * In JOIN notify handling, mark that the cache entry of the
524 client cannot be expired. Can cause crashes on normal
525 server (asserts client->channels). Affected file is
526 silcd/packet_receive.c.
528 * From now on distribution versions are used as protocol versions
529 instead of by default using the Toolkit base version as protocol
530 version. Affected file prepare.
532 * Do not set the locally resolved hostname for local client
533 entry but take what server sends. This way the real hostname
534 is showed in WHOIS for yourself. Affected file is
535 lib/silcclient/idlist.c and lib/silcclient/client.c.
537 * Resolve local info with IDENTIFY when connecting to server.y
539 Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
541 * Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
542 for implied search (not needed on platforms which has native
543 pthreads library). Use --without-pthreads to disable threads.
544 Affected file is configure.in.pre
546 * Fixed --with-iconv on platforms which need to bypass (broken)
547 native iconv(). Affected file is configure.in.pre
549 Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
551 * Moved -C option parsing in Irssi SILC client at same time
552 as other options. The UI was initialized earlier and caused
553 problems on command line. Bug #16. Affected file is
554 irssi/src/silc/core/silc-core.c.
556 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
558 * Added global variable silc_log_timestamp that tells silclog
559 wether to print or not the timestamp in the logging files.
560 Affected file lib/silcutil/silclog.[ch].
562 * Added silcd configuration option Timestamp in the Logging
563 section. Affected file silcd/serverconfig.[ch],
564 doc/example_silcd.conf.in.
566 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
568 * Fixed fingerprint checking to check for entirely empty
569 fingerprint instead of two first bytes when determining
570 if it is set. Bug #18. Affected file silcd/command.c.
572 * Fixed duplicate PKCS name registering to not allow it.
573 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
575 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
577 * Conditionalize non-gcc compiler optimizations for various
578 platforms, enable those commented out. Cleanups.
579 Affected file lib/silcmath/mpi/configure.in
581 Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>
583 * silc_rng_exec_command() left zombie processes if command
584 didn't generate any output. Affected file
585 lib/silccrypt/silcrng.c
587 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
589 * Rewrote iconv checking, introduce --with-iconv for systems
590 which rely on libiconv. Check if iconv() provided by libc
591 is good enough, otherwise demand libiconv. Affected file
594 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
596 * Search for ldopen() also in libc. This enables SIM support
597 on *BSD systems. Based on patch from Alex Zepeda. Affected
598 file configure.in.pre
600 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
602 * Don't call AM_CONDITIONAL conditonally for SILC_THREADS.
603 This fixes prepare on *BSD systems. Affected file
606 Sun Aug 4 15:55:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
608 * More fixed for not having purge timeout for global clients
609 that are on channel. Affected files silcd/command_reply.c
612 * Fixed the rekey protocol to work with backup router connections.
613 Rekey packets are now allowed on disabled connections as
614 well. Affected files silcd/packet_send.c and server.c.
616 * Do not switch to be as backup router when shutting down and
617 closing the primary connection. Affected file silcd/server.c.
619 * Fixed memory leaks in backup router deleting. Added
620 silc_server_backup_free to free all data during shutdown of
621 server. Affected files silcd/server_backup.[ch].
623 Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
625 * Do not process commands if the sock->user_data is NULL.
626 Affected file silcd/command.c.
628 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
630 * Fixed buffer overflow and security problems (loosing bits
631 in CFB encryption) in SILC RNG. Problems reported by
632 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
634 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
636 * Added yet more checks that client is not expired on global
637 list if it is on channels. Affected file is
638 silcd/command_reply.c.
640 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
642 * Merged c0ffee's MIME signal patch which adds support for
643 sending also MIME messages in Irssi SILC Client, and handling
644 received MIME messages in a signal (and perhaps doing something
645 to non-textual MIME messages).
647 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
649 * Fixed pending command deletion in server and client library
650 to check the whole list instead of breaking after first found.
651 The affected files are silcd/command.[ch] and
652 lib/silcclient/command.[ch].
654 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
656 * Return NO_SUCH_CHANNEL error in USERS for channel that is
657 secret or private, otherwise it's possible to find out
658 whether a secret channel exists or not. Affected file
661 * If CMODE change fails during the mode setting, assure that
662 the old mode mask is set for the channel back. Affected
663 file silcd/command.c.
665 * Fixed passphrase saving on +a channel on normal server
666 after successful JOIN command. Affected file silcd/command.c.
668 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
670 * Remove server/router operator privileges in DETACH command,
671 since it's possible to resume to server where these
672 privileges would not be allowed for the client. Affected
673 file silcd/command.c.
675 * Do not set to wait for backup in rehash of the server.
676 Affected file silcd/server.c.
678 * Do not check listener sockets when counting how many
679 socket connections we have. Affected file is
682 * Do not announce disconnected clients that are remaining
683 in history (for WHOWAS). This is because SIGNOFF notify
684 for these has been sent earlier already. Affected file
687 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
689 * Buffer overflow with CUMODE command's mode->mode character
690 conversion. Reported by Ville Räsänen. Affected file
691 lib/silcutil/silcutil.c.
693 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
695 * Allow heartbeat packets to go disabled connections anyway.
696 Affected files silcd/server.c and silcd/packet_send.c.
698 * Do not broadcast New Channel packets with List flag set
699 in the packet to backup routers. The router must check
700 for the correctness of the packets before sending them.
701 It is possible that router will have enforce Channel ID
702 change and this would cause desync in the backup router.
703 Affected file silcd/packet_receive.c.
705 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
706 are handled in list parsing. They are not list packets
707 anymore. Affected file silcd/packet_receive.c.
709 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
711 * Stop waiting for backup router through the timeout, not
712 directly after backup router has arrived. Affected file
715 * Do not re-create channel keys and send them when removing
716 clients in server shutdown. Affected files are
717 silcd/server_internal.h and silcd/server_util.c.
719 * Notify distribution to backup routers was missing from
720 the silc_server_send_notify_dest function which caused
721 desyncing problems with backup router. Affected file is
724 * The client's channel removing was working wrong on
725 backup router. It assumed that it doesn't know global
726 information but backup router does know. For this reason
727 it could remove channel when it wasn't supposed to do that.
728 Affected file silcd/server.c and silcd/server_util.c.
730 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
732 * Stop for a couple seconds after badkup router has become
733 primary router. Affected file silcd/server.c.
735 * Added silc_server_remove_servers_by_server, which is used
736 to remove servers originated from some other server. Also
737 clients of those servers can be removed too. Affected file
738 silcd/server_util.[ch].
740 * When removing clients after a server has signed of remove
741 also all servers behind that server (unless they are known
742 to be available locally), and send SERVER_SIGNOFF for each
743 of the server separately. Also the signed off clients are
744 sent now separately per signed off server. The affected files
745 are silcd/server.c and silcd/server_util.[ch].
747 * All servers added with silc_idlist_add_server must always
748 have both "router" and "connection" pointers set. Otherwise,
749 bad server entries may be left around in the cache.
750 Affected file silcd/command_reply.c.
752 * Do not create the channel key in NEW_CHANNEL packet
753 processing if the channel is empty. Affected file
754 silcd/packet_receive.c.
756 * Completed backup router support for standalone routers.
757 Supports also servers in the cell that do not use the backup
760 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
762 * Fixed a bug in silc_string_regexify which did not add '^'
763 at the start of each string, and thus the matching was
764 not explicit. For example ban list iikone@*!*@* would
765 match also "priikone", which is wrong, it would have to be
766 *iikone@*!*@* to match also "priikone". Affected
767 file lib/silcutil/unix/silcunixutil.c.
769 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
771 * Enable all local server connections before updating client
772 caches when we've become backup router. Otherwise, signoff
773 packets may not reach the clients. Affected files are
774 silcd/server.c and silcd/server_util.[ch].
776 * Fixed a bug in version string parsing which could crash
777 the program with specially formatted version string.
778 Bug reported and patch provided by Ville Räsänen. Affected
779 file lib/silcutil/silcutil.c.
781 * Handle the disconnection immediately when DISCONNECT
782 packet is received in server. Affected file silcd/server.c.
784 * Primary router now waits a short time (10 seconds) for
785 backup router connection before accepting any other
786 connection (except local). Affected file silcd/server.c,
789 * Fixed a crash in client libary in NICK_CHANGE notify when
790 NICK_CHANGE arrived for client entry we are resolving
791 currently. Affected file lib/silcclient/client_notify.c.
793 * Call the sconn->callback completion even if error had
794 occurred. Start reconnecting always if connection to
795 primary router fails during backup router protocol.
796 Affected files silcd/server.c and server_backup.c.
798 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
800 * Added functions silc_server_send_opers and
801 silc_server_send_opers_notify to send packets stricly
802 to operators. Added macro SILC_SERVER_SEND_OPERS macro
803 to send variable argument notify to operators.
804 Affected files silcd/packet_send.[ch] and silcd/server.h.
806 * Removed UMODE rights checking with UMODE_CHANGE notify.
807 Affected file silcd/packet_receive.c.
809 * Server/router operator now receives notify when network
810 switches to backup router and when it resumes the use of
811 primary router. Affected file silcd/server.c and
812 silcd/server_backup.c.
814 * Fixed the updating of client information after backup
815 resuming protocol is over; update all except local clients
816 to the new primary router. The affected file is
819 * Added support for closing active connections in rehash
820 that were unconfigured by the user. Supports currently
821 closing server and router connections. Affected file
824 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
826 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
828 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
829 is NULL since seems that on some platforms NULL is allowed
830 and on some it's not. Fallback encoding is used instead.
831 Affected file lib/silcutil/silcstrutil.c.
833 * Fixed statistics updating for incoming server connection
834 which could cause problems when re-connecting. Affected
837 * Preliminary backup router support for standalone router
838 added. Affected files in silcd/.
840 * Mark server connections in backup router disabled before
841 and after backup protocol. Affected file is
842 silcd/server_backup.c.
844 * Added support for reconnecting to remote server connection
845 even if the protocol fails, and if the configuration wants
846 us to keep trying to connect anyway.
848 Server connection is not allowed to backup router if
849 backup router does not have connection to primary router yet.
851 Affected file is silcd/server.c.
853 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
855 * Added silc_client_udpate_server function to update changed
856 server info. Affected file lib/silcclient/idlist.[ch].
858 * Added check for server entries that are being resolved when
859 notify is received. If being resolved, handle the received
860 notify only after it's resolved so that all notifys are
861 handled in same order as received from the server.
863 Added similar resolver check to channel entries. Every
864 notify that cause resolving of any information that affects
865 channel entry marks the channel entry in waiting state.
866 After whatever resolving is over the waiters are signalled
867 and only then the notifys are handled in the same order
868 as delivered from the server.
870 Affected files are lib/silcclient/idlist.[ch], and
873 * Fixed KILLED notify handling in normal server. Affected
874 file silcd/packet_receive.c.
876 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
877 is locally connected, or was locally connected (but may
878 be detached and connection is not active). Added also
879 SILC_IS_LOCAL for checking this status. Affected files
880 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
881 silcd/server.c and silcd/server_internal.h.
883 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
885 * Don't send or handle TOPIC_SET if topic is already set and
886 is same as being set. Affected files silcd/command.c and
887 silcd/packet_receive.c.
889 * Fixed CMODE change rights checking to work correctly when
890 removing modes by operator. Affected file is
893 * Fixed some handling with New Channel packet in router and
894 fixed some CMODE_CHANGE notify handling in server and router.
895 Affected file is silcd/packet_receive.c.
897 * Changed "disconnect" client operation to include the
898 reason of the disconnection and optional disconnection
899 message. Affected file lib/silcclient/silcclient.h.
901 * Made the compilation of lib/contrib/ stuff conditional.
902 Affected files configure.in.pre, lib/contrib/Makefile.am.
904 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
906 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
907 to the sender of the notify too, to avoid situation where two
908 notifys are in the network at the same time going to oppsite
909 directions. Affected file silcd/packet_receice.c.
911 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
913 * Delete the client from channel even if the cilent->id is
914 NULL. It was possible that client was deleted without
915 removing from channels (theoretically at least). Affected
916 file silcd/server.c and silcd/server_util.c.
918 * Free the client data too when resuming is not successful.
919 Affected file silcd/packet_receive.c.
921 * Merged some code from c0ffee's silc-plugin. Affected files
922 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
924 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
925 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
926 to the primary router connection, the other one returns
927 TRUE if packet must be broadcasted to network.
929 * All notifys that are destined to primary router (to network)
930 are now automatically sent to backup routers even if the
931 router is standalone (and has backup router). Affected files
934 * Added --without-irssi and --without-silcd configuration
935 options for disabling the compilation of these applications.
936 Affected file configure.in.pre and prepare.
938 Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
940 * Implemented SILC_STRING_BMP and SILC_STRING_UNIVERSAL for
941 UTF-8 encoding and decoding. Added also new encodings
942 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
944 Added also SILC_STRING_LANGUAGE which is language and charset
945 specific encoder and decoer for those platforms that support
946 iconv(). It can convert the UTF-8 to and from the locale
947 specific character set.
949 Affected file lib/silcutil/silcstrutil.[ch].
951 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.
953 * Added function silc_get_command_name to the file
954 lib/silcutil/silcutil.[ch].
956 * Improved the server debug output a bit. Affected files are
959 Wed Jun 19 17:46:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
961 * Save the channel passphrase when received succesful JOIN
962 command reply from router, on normal server. Otherwise
963 joinig +a channels from normal server is not possible.
964 Affected file silcd/command.c.
966 * Fixed a bug in TOPIC_SET notify handling. The notifier
967 may be other than client too, like server or channel.
968 It expected it to always be only client and ignored the
969 notify. Affected file silcd/packet_recieve.c.
971 * Removed some (unnecessary) debug printing from
972 lib/silccore/silcid.c and lib/silccore/silcargument.c.
974 * Do not force CMODE_CHANGE when server is announcing new
977 Router announces stuff only after server reannounces channel
978 after CHANNEL_CHANGE notify.
980 These fixes optimizes the announcing procedure, and perhaps
981 fixes some problems too. Affected file silcd/packet_receive.c.
983 * Fixed SERVER_SIGNOFF sending to local clients. It was
984 totally broken and sent the notify to all local clients,
985 instead of only to those that was on same channel as the
986 signing off clients. Affected file silcd/server_util.c.
988 * Added -D option to server. It can be used to give debug
989 level. The levels are from 0 - 99, and are predefined for
990 smooth server debugging. (see silcd.c for the predefined
991 levels). Affected file silcd/server.c.
993 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
995 * Fixed a bug in Irssi SILC client to close the connection
996 properly when disconnecting from server. Affected file
997 irssi/src/silc/core/client_ops.c.
999 Tue Jun 18 17:14:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1001 * When authenticating as founder during JOIN command, check
1002 that the one authenticating becomes the only founder on the
1003 channel. Affected file silcd/command.c.
1005 * Better checking for founder mode setting when CUMODE_CHANGE
1006 notify is received. Affected file silcd/packet_receive.c.
1008 * Close all connections when shutting down the server by sending
1009 DISCONNECT packet. Close all listeners too when shutting
1010 down the server. Affected file silcd/server.c.
1012 * Handle DISCONNECT packet correctly in client library by
1013 calling the "disconnect" client operation. Affected file
1014 lib/silcclient/client.c.
1016 * Handle local errors correctly during resuming. Affected
1017 file lib/silcclient/client.c.
1019 Tue Jun 18 10:26:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1021 * The log file is not dupped internally anymore in
1022 lib/silcutil/silclog.c. Fixed memory leaks too.
1024 * The scheduler now dispatches all pending timeout tasks
1025 when it is uninitialized with silc_schedule_uninit.
1026 Affected file lib/silcutil/silcschedule.c.
1028 Mon Jun 17 21:30:55 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1030 * Added --enable-stack-trace option to configure. Added
1031 memory allocation stack trace support. Added files
1032 lib/silcutil/stacktrace.[ch]. Affected files are
1033 lib/silcutil/silcmemory.[ch].
1035 * Fixed memory leaks from libraries and server. Affected
1036 files around the tree.
1038 * Reverted back a fix made to CUMODE which broke it.
1039 Affected file silcd/command.c.
1041 Sun Jun 16 11:49:45 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1043 * Added SILC_MESSAGE_FLAG_UTF8 to the protocol specs and the
1044 core library, and implemented it. All textual messages SHOULD
1045 use this flag and the message MUST be UTF-8 encoded.
1046 All text messages sent by Irssi SILC client are now UTF-8
1047 encoded (regardless whether the terminal supports UTF-8 or not).
1048 Affected files are lib/silccore/silcchannel.h,
1049 irssi/src/silc/core/silc-servers.c, silc-channels.c and
1052 Sat Jun 15 18:23:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1054 * Added lots of new statistics updating that was missing from
1055 the server and router code. Affected files in silcd/.
1057 * Sending SIGUSR1 signal to server now dumps the current
1058 server statistics into /tmp directory. Affected file is
1061 * ROBODoc documented the lib/silccrypt/silchash.h. Improved
1062 the SILC Hash Interface also. Added new functions
1063 silc_hash_get_name, silc_hash_init, silc_hash_update and
1064 silc_hash_final. Affected file lib/silccrypt/silchash.c.
1066 Sat Jun 15 12:09:14 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1068 * Added some better info printing for client during connecting.
1069 Affected file silcd/server_util.c.
1071 * Implemented the SILC_CHANNEL_UMODE_QUIET mode that can be used
1072 to silence a user on a channel. Affected files are
1073 lib/silcclient/client_channel.c, irssi/src/silc/core/client_ops.c,
1074 irssi/src/fe-common/silc/module-formats.[ch], silcd/command.c
1075 and silcd/packet_receive.c.
1077 * Fixed a fatal bug in handling of malformed command payload.
1078 Affected file silcd/command.c.
1080 * Fixed a double free when announcing channel users to router.
1081 Affected file silcd/server.c.
1083 * After successful authentication to channel founder mode, check
1084 that there isn't anyone else with founder mode on the channel.
1085 The one that authenticated will become founder and anyone
1086 else is demoted. Affected file silcd/command.c.
1088 * Added error printing of any error that has occurred during
1089 any command in client library. Affected file is
1090 irssi/src/silc/core/client_ops.c.
1092 * Removed some error printing from the client library and left
1093 it for the application to worry (from the error status it
1094 receives in 'command' client operation. Affected file is
1095 lib/silcclient/command.c.
1097 Fri Jun 14 22:59:02 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1099 * Added new status types KEY_AGREEMENT_ALREADY_STARTED and
1100 KEY_AGREEMENT_SELF_DENIED to lib/silcclient/silcclient.h.
1101 Starting key agreement with itself is denied. Affected file
1102 is lib/silcclient/client_keyagr.c.
1104 * Fixed some error checkings from the SFTP library which caused
1105 misbehaviour. Affected files are lib/silcsftp/sftp_client.c
1106 and lib/silcsftp/sftp_util.c.
1108 * Added new "debug" and "debug_string" settings to Irssi SILC

1602 lib/silcclient/command_reply.[ch], silcd/command.c,
1603 silcd/command_reply.c and silcd/packet_receive.[ch].
1605 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1607 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
1608 must be handled by the application and should tell the application
1609 that an error message was already printed, and it should print the
1610 config coords (line, filename, ...). Affected files are
1611 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
1613 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
1614 server config parsing code more readable.
1616 Fixed a bug in the fetch_logging() config callback.
1618 Affected files is silcd/serverconfig.c.
1620 * Drop root privileges when started in foreground. Don't drop them
1621 if debugging also. Affected file is silcd/silcd.c.
1623 Mon Apr 8 17:00:41 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1625 * Added more IM-like features by introducing new user modes
1626 for setting various presence information. Added new modes:
1627 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
1628 specs and code. Protocol TODO #19. Affected files are
1629 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
1630 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
1632 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1634 * Added STATS command to the protocol after all, to return
1635 various statistical information about the network. It can
1636 be used by clients to retrieve statistical information, and
1637 servers may use it to to fetch cell and network wide
1638 statistics from router. Updated the protocol specs and
1639 implemented it to the server. Protocol TODO #16.
1640 Affected files are lib/silccore/silccommand, silcd/command.[ch],
1641 silcd/command_reply.[ch].
1643 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1645 * The LIST command reply in client libary now adds new channel
1646 entry if the returned channel doesn't exist yet in cache,
1647 and returns the channel entry to the application in the
1648 command_reply client operation. Affected file is
1649 lib/silcclient/command_reply.c.
1651 * Changed the channel message payload's MAC generation to
1652 include the IV in the MAC as well. This way all relevant
1653 parts of the channel message payload are authenticated also
1654 with the channel message MAC (and not only by packet MAC).
1655 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1656 Affected file is lib/silccore/silcchannel.c.
1658 * Fixed the SKE to save the remote version, since the
1659 silc_ske_parse_version mistakenly checked wrong version,
1660 after it replaced the start payload. Affected files are
1661 lib/silcske/silcske.[ch].
1663 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1665 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
1666 string utility functions. Added there also new functions
1667 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
1668 Affected files lib/silcutil/silcstrutil.[ch].
1670 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
1671 files are lib/silcutil/silcstrutil.[ch].
1673 * Defined that the security property fields in SKE SHOULD be
1674 UTF-8 encoded, defined that version string MUST be US-ASCII
1675 encoded, defined that passphrases sent in connection
1676 authentication protocol MUST be UTF-8 encoded. Implemented
1677 these to the client and server. Defined also that other
1678 passphrases sent in the protocol MUST be UTF-8 encoded.
1679 Affected files are lib/silcske/silcske.c,
1680 lib/silcclient/protocol.c, silcd/protocol.c,
1681 silcd/serverconfig.c, and lib/silccore/silcauth.c.
1683 * Changed the silc_client_close_connection interface to not
1684 need the SilcSocketConnection which should not be visible
1685 to application. Affected files are lib/silcclient/client.c
1686 and lib/silcclient/silcclient.h.
1688 * Rewrote the text for Private Message Key Payload in the
1689 protocol specification. Protocol TODO #11.
1691 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1693 * Upgraded the protocol version to 1.1, updated protocol specs
1696 * Added the nickname as new argument to NICK_CHANGE notify and
1697 added it to protocol specs and implemented it to client and
1698 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
1699 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
1700 lib/silcclient/client_notify.c.
1702 * Added the killer's client ID to the KILLED notify and added
1703 it to protocol specs and implemented it to client and server.
1704 Protocol TODO #13. Affected files are silcd/command.c,
1705 silcd/packet_receive.c, packet_send.[ch],
1706 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1707 The killer's client entry is now returned to application in
1708 the `notify' client operation.
1710 * Fixed the Max Argument fields that had too large value set
1711 in the protocol specs. Protocol TODO #14.
1713 * Added the LEAVE command reply to return the ID of parted
1714 channel. Updated protocol specs and implemented it to the
1715 client and server. Protocol TODO #15. Affected files are
1716 silcd/command.c, lib/silcclient/command_reply.c. The channel
1717 entry is now returned to application in the `command_reply'
1720 * Rewrote the version SKE version checking in client libary
1721 and in server to use the silc_parse_version_string. Affected
1722 files are lib/silcclient/protocol.c, silcd/protocol.c.
1724 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
1725 commands that was missing it, and updated protocol specs and
1726 the server implementation. Protocol TODO #10. The affected
1727 file is silcd/command.c.
1729 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1730 generic reply to a generic request (REQUEST flag), and
1731 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1732 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1733 to define the payload for DATA flag. Added the flags to
1734 the implementation. Protocol TODO #9. Affected file is
1735 lib/silccore/silcchannel.h.
1737 Changed the client library to return the message length
1738 to application as well in the channel_message and private_message
1739 client operations. Affected files are
1740 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
1741 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
1742 and lib/silcclient/client_ops_example.c.
1744 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
1745 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
1746 the channel. Updated protocol specs and impelemented this
1747 to client and server. Protocol TODO #6. Affected files are
1748 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
1749 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
1751 Added new options m and M to CMODE command in Irssi SILC
1752 client to set these modes.
1754 * Deprecated all administrative commands from SILC protocol
1755 since they are highly implementation specific commands.
1756 Updated protocol specs. Moved the old commands in
1757 implementations to private range of command types. Affected
1758 files are silcd/command.c, lib/silcclient/command.c and
1759 lib/silcclient/command_reply.c. Protocol TODO #8.
1761 * Fixed a bug in server where sending unknown command crashes
1762 the server. Affected file silcd/command.c.
1764 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1766 * Added SILC_PROTOCOLVERSION macro to check protocol version
1767 of a socket connection. The affected file is
1768 lib/silcutil/silcsockconn.h.
1770 * Added better error logging in rekey protocol. Affected file
1773 * Do not check public key types in SKE during rekey. Affected
1774 file lib/silcske/payload.c.
1776 * Fixed the rekey protocol with PFS, which was totally broken.
1777 Affected file silcd/protocol.c.
1779 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1781 * Some client implementations quit network by doing first LEAVE
1782 and then immediately SIGNOFF (like Bombyx). We now do check
1783 after a short time after LEAVE notify and check whether the
1784 client is still valid after LEAVE, and if not we remove it from
1785 cache. Affected file is lib/silcclient/client_notify.c.
1787 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1789 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1790 it's good not to have security holes here.
1792 * Fixed a negative refcount situtuation for the config context.
1793 Affected file is silcd/serverconfig.c.
1795 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1797 * ROBOdoc documented lib/silcutil/silcutil.h.
1799 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1801 * Optimized even more the SilcPacketContext structure. Now
1802 totally saved 16 bytes of memory per context after optimization.
1803 Affected files are lib/silccore/silcpacket.[ch].
1805 * Made strict checks for valid SILC IDs. Affected file is
1806 lib/silccore/silcid.c.
1808 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1810 * Changed the object argument for silc_cipher_register,
1811 silc_hash_register, silc_hmac_register and silc_pkcs_register
1812 to const. Affected files are lib/silccrypt/silccipher.[ch],
1813 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1815 * Changed the silc_get_username and silc_get_real_name to
1816 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1818 * Fixed the Irssi SILC Client to use the silc_get_username and
1819 silc_get_real_name insted of glib routines since the glib
1820 routines only corrupt stack. Fixes the Irssi SILC to work in
1821 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1823 * Fixed the Irssi to not use g_get_home_dir since it crashes
1824 or returns garbage on cygwin and corrupts stack. Added function
1825 get_home_dir to Irssi routines. Affected files are
1826 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1828 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1830 * Made some structure optimizations. SFTP memory FS MemFSEntry
1831 entry structure. Optimized SilcTask structure. Optimized
1832 SilcPacketContext structure.
1834 Affected files lib/silcsftp/sftp_fs_memory.c,
1835 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1837 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1839 * And yet again reverted back the config thing since Johnny
1840 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1843 * Fixed memory leaks from config object. Affected files are
1844 silcd/serverconfig.[ch].
1846 * Added support for adding new connections to the server in rehash.
1847 After rehash they take effect.
1849 Added support for changing the maximum allowed connections in
1850 rehash. The number can grow but going smaller is not supported.
1852 Added function silc_server_num_sockets_by_remote to the
1853 silcd/server_util.[ch].
1855 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1857 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1859 * Added preliminary checking during config parsing for a valid
1860 public/private key and removed further checks in the code.
1861 Affected files are silcd/serverconfig.[ch], server.c.
1863 * Moved functions silc_server_drop() and silc_server_daemonise()
1864 from server.c to silcd.c since they are stricly related to
1865 the application activity.
1867 * Reverted a small part of the automatic ref/unref since
1868 it caused a double unref in some situations. Affected
1869 files are silcd/silcd.[ch], server.c, serverconfig.c.
1871 * Added some .cvsignore files in the lib directory.
1873 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1875 * Fixed silc_net_gethostbyaddr to correctly resolve by
1876 address. Affected file lib/silcutil/silcnet.c.
1878 * Fixed the notify relaying to client. The HMAC to be used
1879 with relayed packets ws wrong and caused decryption failure
1880 at the client end. Affected file is silcd/packet_receive.c.
1882 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1884 * Created new branch silc_protocol_1_0_branch.
1886 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1888 * Changed the silc_server_config_* routines to be SilcServer
1889 independent. They are now officially application specific code
1890 and not part of generic server implementation. Affected files
1891 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1893 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1895 * Added automatic referencing of config context in the
1896 silc_server_config_alloc, and automatic unreferencing in the
1897 silc_server_config_destroy. Affected files are
1898 silcd/serverconfig.[ch], silcd/silcd.c.
1900 * Fixed the silc_log_quick handling in the logging routines.
1901 It didn't log quickly when it was TRUE. Affected file is
1902 lib/silcutil/silclog.c. Also the flush delay was set even
1903 if it was 0 in config file. Affected file is
1904 silcd/serverconfig.c.
1906 * Added support for changing key pair of the server in rehash.
1907 Affected file silcd/server.c.
1909 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1911 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1912 too early, before getting the channel entry. Affected file
1913 is silcd/packet_receive.c.
1915 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1917 * Added functions silc_server_config_[ref/unref], these are used
1918 to prevent that the config object is destroyed.
1920 No longer directly affect global variables silc_log_quick and
1921 silc_log_delay, they are first cached inside the config object
1922 and then applied with silc_server_config_setlogfiles().
1924 silc_server_config_set_defaults() is now internal to
1925 serverconfig.c, there are no reasons to show this internal stuff
1928 Affected files are silcd/serverconfig.[ch].
1930 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1931 fprintf's to stderr, since some code may be executed again after
1932 the server went into the background. Affected files are
1935 * Added rehash support. Added function silc_server_rehash() that
1936 will perform all the basic tasks of the rehashing procedure.
1938 * Added command line option `-x, --hexdump'. This will enable the
1939 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1940 The option `--hexdump' implies `--debug'.
1942 * Fixed a bad bug in the logging APIs (silcutil library) where
1943 the application would crash after calling silc_log_reset_all().
1945 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1947 * Fixed the KICKED notify handling in client library to
1948 correctly remove the channel and all entries from the
1949 channel when I was kicked. This bug crashed the client.
1951 Fixed yet another but in KICKED notify handling to remove
1952 the kicked client correctly from the channel.
1954 Affected file is lib/silcclient/client_notify.c.
1956 * Fixed a minor bug in looking up correct client entry
1957 in KICKED notify in server. Affected file is
1958 silcd/packet_receive.c.
1960 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1961 sources correctly to distribution. Fixes --with-gmp option.
1963 * Removed the manual rehashing from ID Cache, and changed it
1964 to use the SILC Hash Table's auto rehash feature. Affected
1965 file is lib/silccore/silcidcache.c.
1967 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1969 * Fixed a bug in the silc_client_nickname_format function that
1970 handles the multiple same nickname formatting. Two clients
1971 with same nickname caused problems after the first one left
1972 and rejoined. It didn't format the nickname correctly.
1973 Affected file is lib/silcclient/idlist.c.
1975 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1977 * Don't change the topic if olod topic is same as new one.
1978 Affected file is silcd/packet_receive.c.
1980 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1982 * Added cross-reference support to the SILC Documentation
1983 generator. All types across all HTML files are now cross-
1984 referenced. Affected files util/robodoc/generator.c and
1985 scripts/silcdoc/silcdoc.
1987 * Added file lib/silcutil/silctypes.h to include all the
1988 arithmetic type definitions and some macros. Removed
1989 includes/bitmove.h and moved macros to silctypes.h.
1991 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1993 * Merged bugfixes for Irssi SILC client from irssi.org CVS.

1997 * Added `type' argument to silc_id_payload_parse_id function which
1998 now returns the type of the ID to the sent pointer. Affected
1999 file is lib/silccore/silcid.[ch].
2001 * Added check for CMODE_CHANGE notify type that mode change is
2002 allowed by the sender. Affected file silcd/packet_receive.c.
2004 * Added check for CUMODE_CHANGE notify type that mode change is
2005 allowed by the sender. Affected file silcd/packet_receive.c.
2006 Added the ID type as CUMODE_CHANGE notify type as argument
2007 to the `notify' client operation. Affected files are
2008 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
2010 * Added function silc_client_add_server to the client library.
2011 Added support for resolving also channel and server info when
2012 received unknown entity in notify packet. Affected files are
2013 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
2015 * Added function silc_command_get_status to return the command
2016 status from the command reply's argument payload. Affected files
2017 are lib/silccore/silccommand.[ch].
2019 * Added check for KICKED notify type that the kicking is
2020 allowed by the client. Affected file silcd/packet_receive.c.
2022 * Created function silc_get_input which can be used to get input
2023 (echo on or off) from user on command line. Affected files are
2024 lib/silcutil/silcutil.[ch].
2026 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2028 * Optimized silc_server_packet_relay_to_channel function.
2029 Added new function silc_channel_message_payload_encrypt which
2030 can be called directly if channel message payload needs to
2031 be encrypted and is already encoded (no need to call _encode
2032 function). Packet relaying is now done by router without any
2033 extra memory allocations. Affected files are
2034 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
2035 silcd/packet_send.c.
2037 * Fixed the INVITE notify handling. It took wrong arguments
2038 as invite list and invite delete. Affected file is
2039 silcd/packet_receive.c.
2041 * Added check for TOPIC_SET notify type that the topic change is
2042 allowed by the client. Affected file silcd/packet_receive.c.

2047 * Changed the silc_server_client_on_channel to return the
2048 SilcChannelClientEntry as well. Moved the function
2049 silc_server_check_cmode_rights to server_util.[ch].
2050 Affected files are silcd/server_util.[ch], silcd/command.c.
2052 * Added function silc_server_check_umode_rights to check whether
2053 changing client's user mode is allowed. Added check for
2054 UMODE_CHANGE notify type that the umode change is allowed
2055 by the client. Affected files are silcd/server_util.[ch],
2056 silcd/packet_receive.c and silcd/command.c.
2058 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2060 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
2061 ID length. It ignored that ID can be IPv6 based as well.
2062 Affected file lib/silccore/silcpacket.h.
2064 * Fixed the silc_id_id2str and silc_id_str2id to take the
2065 IPv6 address offset's into consideration. Affecte file is
2066 lib/silccore/silcid.c.
2068 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2070 * Fixed the internal Unix scheduler functions to check for
2071 NULL context they may receive. The affected file is
2072 lib/silcutil/unix/silcunixschedule.c.
2074 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
2076 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
2077 can specify different directory with --home command line
2078 parameter. Affected files irssi/src/silc/core/client_ops.c,
2081 * SILC-specific commands aren't now executed if the active server
2082 isn't of SILC-type, so there won't be problems with having
2083 IRC and SILC protocol support in same client. Affected files
2084 irssi/src/silc/core/silc-channels.c, silc-servers.c,
2087 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2089 * Improved the signal support in SILC Schedule. Added new
2090 function silc_schedule_signal_call which is used by application
2091 to mark a signal to be called. It is now safe to perform
2092 any kind of tasks in signal callbacks since it is guaranteed
2093 that the application specified signal callback is called
2094 after the signal is over. Affected files are
2095 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
2097 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2099 * Added `name' field to SilcChannelPrivateKey to represent
2100 application given name for the key. Moved also the context from
2101 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
2102 Added the `name' argument also to the function
2103 silc_client_add_channel_private_key.
2105 Added function silc_client_current_channel_private_key to set the
2106 current channel private key in use.
2108 Added "change" command to KEY command which can be used to change
2109 the current channel private key. Bound the command also to
2110 alt+K (Alt+Shift+k).
2112 Also affected files lib/silcclient/client_channel.c,
2113 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
2115 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2117 * Added silc_rng_get_byte_fast function in to the
2118 lib/silccrypt/silcrng.[ch].
2120 * Changed the interface of silc_packet_assemble and the
2121 silc_packet_send_prepare. If silc_packet_assmble is now
2122 called the application does not call silc_packet_send_prepare
2123 because the library will call it automatically. These
2124 interfaces now also return a reference to the outgoing buffer
2125 which includes the assembled packet, which the application can
2126 use to encrypt the packet.
2128 Affected files are lib/silccore/silcpacket.[ch],
2129 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
2130 silcd/packet_send.c, server_backup.c and packet_receive.c.
2132 * Fixed a packet sending bug on very high load, where outgoing
2133 packet queue wasn't handled correctly and packets got corrupted.
2134 Affected files are lib/silcutil/*/silc*sockconn.c,
2135 lib/silcclient/client.c and silcd/server.c.
2137 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2139 * Added macro SILC_PACKET_DATALEN which can be used during
2140 packet assembling to check whether the data to be added to
2141 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
2142 len is truncated until it fits it.
2144 Added checks for maximum length of channel message payload and
2145 private message payload also.
2147 Added checks for maximum packet length in server and in
2150 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
2151 lib/silcclient/client.c, lib/silccore/silcchannel.c and
2152 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
2153 lib/silcclient/client_prvmsg.c.
2155 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2157 * Added silc_server_packet_queue_purge call to the
2158 silc_server_disconnect_remote to assure that all data in the
2159 queue before disconnecting is sent to the network. Affected
2160 file silcd/server.c.
2162 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2164 * Added the deleting of server's own ID cache entry to the
2165 silc_server_free function. Free also everything else that
2166 has been allocated in silc_server_init. The affected file
2169 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2171 * Added functions silc_parse_version_string, silc_version_to_num,
2172 and silc_ske_parse_version to parse SILC protocol style version
2173 strings. Affected files lib/silcutil/silcutil.[ch] and
2174 lib/silcske/silcske.[ch].
2176 * Added new configuration params: version_protocol, version_software
2177 and version_software_vendor to specify what version the remote
2178 host must at least be to be able to connect to server. The vendor
2179 string can be regex matched too. Added new function
2180 silc_server_connection_allowed to check maximum number of allowed
2181 connections, and allowed versions for incoming connections.
2182 Affected files are silcd/server.c, server_util.[ch] and
2185 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2187 * Added preliminary support for signals in scheduler. The
2188 signals we care about are now blocked always when the scheduler
2189 is locked. This way we can synchronise the use of signal with
2190 scheduler. It is guaranteed that when signal occurs the scheduler
2191 is not locked, and thus new tasks can be safely added to the
2194 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
2195 to silc_schedule_internal_init and silc_schedule_internal_uninit.
2196 Added new platform specific routines
2197 silc_schedule_internal_signals_[un]block and
2198 silc_schedule_internal_signal_[un]register.
2200 Added new functions to SILC Schedule API:
2201 silc_schedule_signal_[un]register. Each signal that application
2202 is going to use should be registered to the scheduler.
2204 Affected files are lib/silcutil/silcschedule.[ch],
2205 lib/silcutil/*/silc*schedule.c.
2207 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2209 * Check for unauthenticated client and server in the
2210 silc_server_new_client and silc_server_new_server functions.
2211 Affected file silcd/packet_receive.c.
2213 * Added function silc_string_is_ascii to check whether given
2214 string is 7-bit ASCII string. Affected files are
2215 lib/silcutil/silcutil.[ch].
2217 * Added function silc_id_is_valid_server_id into the
2218 silcd/serverid.c and added checking for valid Server ID's in
2219 silc_server_new_server. The Server ID must always be based
2220 on the server's public IP address.
2222 * Added logging of DISCONNECT packet message in the server.
2223 Affected file silcd/server.c.
2225 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2227 * Changed all library interfaces that use Global RNG to also
2228 accept SilcRng as argument. Affected files are
2229 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
2230 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
2231 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
2232 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
2233 lib/silccrypt/rsa.c.
2235 * Added function silc_pkcs_generate_key to the
2236 lib/silccrypt/silcpkcs.[ch] for applications so that they
2237 don't need to do pkcs->pkcs->init calls anymore.
2239 * Remove SilcSocketConnection from the SFTP API since it really
2240 wasn't needed there. The application has the information
2241 saved in its contexts anyway and the SFTP layer doesn't need
2242 know about it. Affected files lib/silcsft/silcsftp.h and
2243 lib/silcsftp/sftp_[server/client].c.
2245 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
2246 The SilcSimContext is not SilcSim.
2248 * Fixed possible buffer overflows in silc_id_render in the
2249 lib/silcutil/silcutil.c.
2251 * On EPOC the global crypto module lists are not used at all
2252 in the crypto library. Added support for using the constant
2253 algorithm list on EPOC. Affected files are
2254 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
2257 * Fixed the handling of third parameter of KICKED notify, since
2258 it was mistakenly updated to SILC Protocol 1.0 even though it
2259 is to be included in 1.1. Since it is not in 1.0 it is not
2260 mandatory, and this fix now handles it only if it is provided,
2261 and it is not error if it is not provided. Affected file
2262 lib/silcclient/client_notify.c.
2264 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2266 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
2267 client. Affected file irssi/src/silc/core/client_ops.c.
2269 * Merged with Irssi 0.8.4 from irssi.org CVS.
2271 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2273 * Check for valid socket connection in client entries before
2274 sending any messages. Fixes a crash, but doesn't fix some
2275 other underlaying bug that is lurking there. Affected
2276 file silcd/packet_send.c.
2278 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
2280 * $usermode, $cumode and $cumode_space expandos shouldn't do
2281 anything with non-SILC server records. Affected file
2282 irssi/src/silc/core/silc-expandos.c
2284 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2286 * Fixed the silc_net_check_[host/local]_by_sock to support
2287 IPv6 bound sockets as well. Now they can return IPv6 addresses
2288 as well. Affected file lib/silcutil/silcnet.c.
2290 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
2291 Affected lib/silcutil/unix/silcunixnet.c.
2293 * Fixed ID rendering (at least on some platforms, not NetBSD)
2294 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
2296 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2298 * Added silc_hash_public_key and silc_hash_public_key_compare
2299 functions to be used with SilcHashTable. They can be used to
2300 hash public keys and compare public keys in hash table. Affected
2301 file lib/silcutil/silcutil.[ch].
2303 * Added support for specifying multiple public keys for Client
2304 connection section in server configuration file. This makes it
2305 possible to accept multiple public keys from same host, or to
2306 make a section that accepts any incoming host, and have the
2307 accepted public keys listed in the section.
2309 Added functions silc_sever_[find/get]_public_key, added the
2310 support for this actually to all connection sections but only
2311 the Client section is currently allowed to specify multiple
2314 Affected files are silcd/server.c, server_internal.h,
2315 command.c, protocol.c, server_util.[ch], packet_receive.c.
2317 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2319 * Merged Irssi 0.8.2 from irssi.org CVS.
2321 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2323 * If silc_debug is TRUE, also output standard logging messages
2324 to stderr with the debug output.
2326 Made silc_log_reset_all() flushing all channels before returning.
2327 Also fixed some documentation typos.
2329 Affected files are lib/silcutil/silclog.[ch].
2331 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2333 * Fixed the server to check correctly the amount of connections
2334 from single host, by checking also the type of the connection.
2335 Fixed also the comparison of number of connections and number
2336 of allowed connections. Affected files are silcd/server.c,
2339 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2341 * Fixed the USERS command reply to save the user's mode on the
2342 channel as well. Fixed JOIN command reply to check whether a
2343 client is on channel already and not join it twice. Affected
2344 file lib/silcclient/command_reply.c.
2346 * Added new file silc-expandos.c into irssi/silc/core/ to return
2347 various stuff for various signal for the statusbar etc. updating.
2348 Now Irssi SILC client prints channel user modes etc. on the
2351 * The user mode (like server/router operator changes) is now shown
2352 on the Irssi SILC client's statusbar. The affected files are
2353 irssi/src/silc/core/client_ops.c, silc-expandos.c.
2355 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2357 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
2358 to SILC_SCHEDULE_[UN]LOCK macros.
2360 * Added more error printing to logs in server code. Affected
2361 files silcd/server.c and silcd/protocol.c.
2363 * Fixed -S option parsing in Irssi SILC Client. Affected file
2364 irssi/src/silc/core/silc-core.c.
2366 * Added silc_buffer_alloc_size function. Affected file is
2367 lib/silcutil/silcbuffer.h.
2369 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2371 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
2372 constants. Affected files in
2373 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
2376 * Changed the internal SFTP Memory FS table to const. Affected
2377 file lib/silcsftp/sftp_fs_memory.c.
2379 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2381 * Fixed the buffer formatting and unformatting routines to
2382 check the size of 64 bits types with sizeof(). Affected
2383 file is lib/silcutil/silcbuffmt.c.
2385 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2387 * Removed 0.6.x backwards support.
2389 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2391 * Changed all integer type names:
2392 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
2393 to avoid collisions with other libraries using same type names
2396 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2398 * Added `prefer_ipv6' argument to the functions
2399 silc_net_gethostbyname[_async]. If it is TRUE it will return
2400 IPv6 address over IPv4. If FALSE IPv4 address is returned
2401 even if IPv6 address was found. Affected files
2402 lib/silcutil/silcnet.[ch].
2404 * Added support silc_net_create_connection[_async] to fallback
2405 to IPv4 address if IPv6 address could not be used (like if
2406 it doesn't work on a specific system). Affected file in
2407 lib/silcutil/unix/silcunixnet.c.
2409 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2412 of the max tasks handling capabilities of the scheduler.
2413 Affected files lib/silcutil/silcschedule.[ch].
2415 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2417 * Added automatic extern "C" { ... } for C++ compilers so the
2418 application does not need to define them. Affected file
2419 includes/silcincludes.h.
2421 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
2422 old name went against naming convention. Applications now
2423 include "silcclient.h" instead of "clientlibincludes.h".
2424 Removed includes/clientlibincludes.h, it is redundant now.
2426 * Renamed includes/version.h to silcversion.h.
2428 * Added really preliminary support for OS/2 into the util
2429 library. Only thread & mutex API is implemented, others
2430 are still to be implemented. Created the lib/silcutil/os2/
2431 directory. Created also file includes/silcos2.h.
2433 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2435 * Added preliminary BeOS support into the util library.
2436 Created lib/silcutil/beos/, and implemented all the needed
2437 functions to support SILC on BeOS. Created also file
2438 includes/silcbeos.h.
2440 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
2442 * Added proper initializations to silc's irssi code, so it's
2443 now possible to load it as module. Affected files
2444 irssi/src/silc/core/silc-core.c,
2445 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
2447 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2449 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
2452 * Fixed the silcdoc document generator to correct generate
2453 docs from all kinds of filenames. Affected files are
2454 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
2456 * ROBOdoc documented lib/silcutil/silcmemory.h.
2457 Added also new function silc_memdup.
2459 * Removed lib/silcutil/silcbufutil.h and moved those routines
2460 to the lib/silcutil/silcbuffer.h.
2462 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2464 * Added `user_count' to the SilcChannelEntry which now tells the
2465 number of users on the channel. The user count is now saved
2466 in normal server of global channels as well. Affected files
2467 silcd/server.c, idlist.h, packet_receive.c and command.c.
2469 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
2470 include file utility functions.
2472 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
2473 instead of calling directly OS routines.
2475 * Fixed NICK change printing in Irssi SILC Client. Fixed
2476 KICKED notify printing in Irssi SILC Client. Affected file
2477 irssi/src/silc/core/client_ops.c.
2479 * Fixed a NICK change bug in client library, to not recreate the
2480 client_entry->channels hash table everytime nick is changed.
2481 Affected file lib/silcclient/client.c.
2483 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2485 * ROBOdoc documented the lib/silcske/silcske.h, and improved
2486 the SKE interface a bit.
2488 * Fixed padding problem in PKCS#1. The padding was not actually
2489 random since the random number generator was used incorrectly.
2490 This security bug affects only when encrypting with PKCS#1, and
2491 it is not currently used at all in SILC. SILC only use signing
2492 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
2494 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2496 * Rewrote the notify handling in Irssi SILC client to not call
2497 the events as signals. Fixes problems with Perl support.
2498 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
2500 * Send the auto-nicking NICK command in client library with
2501 little timeout after connecting. The affected file is
2502 lib/silcclient/client.c.
2504 * Added following new config file settings:
2505 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
2506 key_exchange_timeout, conn_auth_timeout, connections_max,
2509 Implemented all the new config settings handling in the server.
2511 Optimized the use of SKE Mutual flag usage. Use it only
2512 if connection authentication protocol is not based in public
2515 Renamed all SilcServerConfigSection* to SilcServerConfig*
2516 to have a bit shorter names.
2518 Affected files silcd/serverconfig.[ch], server.[ch], and
2521 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2523 * Cleaned up the listening sockets code, preparing for the rehash
2524 support. Affected file is silcd/server.c.
2526 * Fixed some output messages. Affected files are silcd/silcd.c,
2529 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2531 * Create lib/doc/silcrng_intro.html document as introduction
2532 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
2534 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2536 * Fixes to the silcd config template. Affected file is
2537 doc/example_silcd.conf.in.
2539 * Removed type casts from silc_calloc(), conforming to the
2540 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
2542 * Removed param_name member from client, server, and router
2543 section structs, now identifying the param directly.
2545 Added CONFIG_FREE_AUTH macro in config file parsing.
2547 Affected files are silcd/serverconfig.[ch].
2549 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
2551 * Fixed command line parameter handling. All SILC initialization
2552 is now done in silc_core_init() which also fixes autoconnecting
2555 Affected files irssi/src/silc/core/silc-core.c,
2556 irssi/src/fe-text/silc.c.
2558 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2560 * Added new configuration options and blocks:
2561 keepalive_secs, reconnect_count, reconnect_interval,
2562 reconnect_interval_max, reconnect_keep_trying and
2563 require_reverser_lookup. Added ConnectionParam block, and
2564 implemented the connection parameters when connecting as
2565 initiator and when accepting connections as responder.
2567 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
2568 whether given configuration value has been given already.
2570 Affected files silcd/serverconfig.[c], server.[c].
2572 * Splitted the doc/example_silcd.conf.in. Separated the crypto
2573 algorithm parts and created new file silcalgs.conf, that
2574 is now included from the example_silcd.conf.in.
2576 * Optimized the silc_server_connect_to_router_second to take
2577 the connection configuration object from the SilcServerConnection
2578 object instead of finding it during the connecting phase.
2579 Added the configuration object to SilcServerConnection struct.
2580 Affected files silcd/server_internal.h, server.c.
2582 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2584 * Add the client on channel after it was resolved at the
2585 channel message receiving, and it was not already on the
2586 channel. Affected file lib/silcclient/client_channel.c.
2588 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2590 * Fixed the public key authentication to allocate always the
2591 destination signature buffer instead of using static buffer.
2592 Affected file silcd/protocol.c.
2594 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2596 * Unified the serverconfig.[ch]'s helper function interface.
2597 Affected file silcd/serverconfig.[ch].
2599 * Removed doc/example_silc.conf.in since it is redundant.
2600 The make install will now install irssi/silc.conf file.
2602 * Added new Passphrase and Publickey authentication methods to
2603 config file, allowing both public key and passphrase based
2604 authentication to be set at the same time.
2606 Added `prefer_passphrase_auth' setting in config file which
2607 can be used to set to prefer passwd auth if both passwd and
2608 public key is set. If not set, public key is preferred.
2609 This has effect only when being initiator (responder will try
2612 Added support for authentication with passphrase and public key
2613 at the same time. The passphrase is tried first always since
2614 it is faster to check.
2616 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2618 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2620 * Merged the new SILC Config library, with the server parsing
2621 support. Read the header file silcconfig.h or the toolkit
2622 documentation for the news. Affected files are
2623 doc/example_silcd.conf.in lib/silcutil/silcconfig.[ch]
2624 silcd/command.c silcd/packet_receive.c silcd/packet_send.c
2625 silcd/protocol.c silcd/server.c silcd/server_backup.c
2626 silcd/serverconfig.[ch] silcd/silcd.c.
2628 * Fixed some silclog documentation. Affected file is
2629 lib/silcutil/silclog.h.
2631 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2633 * The silc_cipher_register, silc_hash_register and
2634 silc_hmac_register now checks if the object to be registered
2635 is registered already. Affected files are
2636 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
2638 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2644 * Allow zero length channel messages inside the Channel Message
2645 Payload. Affected file lib/silccore/silcchannel.c.
2647 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
2648 as header filenames.
2650 * Removed lib/silcclient/README and created HTML file
2651 lib/silcclient/silcclient_using.html, which is now included
2652 as part of Toolkit documentation.
2654 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2656 * Fixed CUMODE_CHANGE notify handling to change the mode of
2657 correct client. Affected file lib/silcclient/client_notify.c.
2659 * Make silc_rng_alloc fail if it cannot allocate the sha1
2660 hash algorithm. Affected file lib/silccrypt/silcrng.c.
2662 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2664 * Fixed the file transfer's key agreement payload to include
2665 zero port also if the hostname is NULL because it could not
2668 Call file transfer monitor callback now also if error occurs
2669 during key agreement protocol.
2671 Changed the silc_client_file_send interface to return the
2672 SilcClientFileError instead of session id. The session ID
2673 is returned into pointer provided as argument.
2675 Check that the file exists locally before sending the
2676 file transfer request at all.
2678 Affected file lib/silcclient/client_ftp.c, silcapi.h.
2680 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
2681 error than can occur while key agreement protocol. Affected
2682 file lib/silcclient/silcapi.h.
2684 * Fixed the event_mode CMODE handler to not crash when mode
2685 is changed and +k mode is set in the channel. Affected file
2686 irssi/src/silc/core/silc-channels.c.
2688 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2689 SILC_LOG_WARNING to give out Warning and not Error. Affected
2690 file lib/silcutil/silclog.c.
2692 * Fixed the channel message payload decryption in the function
2693 silc_channel_message_payload_decrypt to not modify the original
2694 buffer before it is verified that the message decrypted
2695 correctly. Otherwise, next time it is called with correct
2696 channel key it won't encrypt since the payload is corrupted.
2697 Affected file lib/silccore/silcchannel.c.
2699 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2701 * Do not constantly resize the window. A fix patch by cras.
2702 Affected file irssi/src/fe-text/screen.c.
2704 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2706 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
2707 Affected file lib/silcutil/silcnet.c.
2709 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2711 * Fixed a bug in hash table internal routine for traversing
2712 the table with foreach callback. The current entry may
2713 become invalid in the callback but it was referenced after
2714 the callback returned.
2716 Do not allow auto rehashing of hash table during the
2717 silc_hash_table_foreach operation, for same reasons as it is
2718 not allowed for SilcHashTableList. Affected files are
2719 lib/silcutil/silchashtable.[ch].
2721 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2723 * Defined DLLAPI into silcincludes.h and silcwin32.h for
2724 Win32 DLL. extern's in header files are now declared with
2727 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2729 * Fixed private message handling. It used some old code that
2730 caused the client to crash. Affecte file is
2731 lib/silcclient/client_prvmsg.c.
2733 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2735 * Added function silc_client_add_channel,
2736 silc_client_replace_channel_id, and removed functions
2737 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2738 from client library.
2740 * Added cross reference of the joined channels to the
2741 SilcClientEntry, and changed the SilcChannelEntry's
2742 users list to SilcHashTable. The affected files are
2743 lib/silcclient/idlist.[ch].
2745 * Fixed a bug in hash table tarversing. While the hash table
2746 is traversed with SilcHashTableList the table must not be
2747 rehashed. It is now guaranteed that auto rehashable tables
2748 are not rehashed while tarversing the list. Also defined that
2749 silc_hash_table_rehash must not be called while tarversing
2750 the table. Added function silc_hash_table_list_reset that must
2751 be called after the tarversing is over. The affected files are
2752 lib/silcutil/silchashtable.[ch].
2754 * Changed all hash table traversing to call the new
2755 silc_hash_table_list_reset in server and in client library.
2757 * Added function silc_client_on_channel to return the
2758 SilcChannelUser entry if the specified client entry is joined
2759 on the specified channel. This is exported to application as
2760 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2762 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2764 * Fixed founder regaining problem with JOIN command on normal
2765 server. The notify for mode change must be sent always and
2766 not only if !cmd->pending. Affected file silcd/command.c.
2768 * Fixed the WHOWAS command's reply sending to support the
2769 lists correctly. Affected file silcd/command.c.
2771 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2773 * When sending JOIN command to router for processing the
2774 sender's old command identifier was not saved back to the
2775 sender's command context, fixed now. The affected file is
2778 * Create the key in JOIN command of the router did not return
2779 the channel key, added check for this. Affected file is
2782 * Fixed a channel ID update bug in JOIN command reply. Do
2783 not directly upgrade the ID but call the function
2784 silc_idlist_replace_channel_id if the ID was changed.
2785 Affected file silcd/command_reply.c.
2787 * Fixed memory leaks from command calling if it would fail.
2788 Affected file silcd/command.c.
2790 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2792 * Applied patches from cras:
2794 Memory leak fixes around libaries, irssi window resize fix,
2795 new silclist.h and silcdlist.h, all extern inline changed to
2798 * Removed dotconf from lib/dotconf, not needed anymore.
2800 * Removed TRQ from lib/trq, not needed anymore.
2802 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2803 with server connections. Later this will be configurable
2804 in config file after new config file is done. Affected file
2807 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2809 * Fixed a crash in server related to channel announcements.
2810 Affected file silcd/server.c.
2812 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2814 * Fixed memory leaks in silc_server_create_new_channel*
2815 functions. Affected file silcd/server.c.
2817 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2818 which ID was changed. This way the router will send the
2819 user list for the channel again, and server won't be in
2820 desync in some rare circumstances. Affected file is
2821 silcd/packet_receive.c.
2823 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2825 * Check for NULL socket pointer in the function
2826 silc_server_packet_send_to_channel_real. Affected file
2827 silcd/packet_send.c.
2829 * Fixed the BAN notify handling to correctly remove ban
2830 list. Affected file silcd/packet_receive.c.
2832 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2834 * Fixed some header addition to Toolkit distribution in
2835 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2837 * Added lib/silcclient/client_ops_example.h as an template
2838 file for application programmers to quickly start using
2839 the SilcClientOperation functions in their application.
2840 Updated the lib/silcclient/README as well to tell about this
2841 nice file made available.
2843 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2845 * Call silc_server_remove_from_channels when removing client
2846 entry when NO_SUCH_CLIENT_ID was received. Affected file
2847 is silcd/command_reply.c.
2849 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2851 * Added server & router operator statistics updating. Affected
2852 file silcd/packet_receive.c and silcd/command.c.
2854 * Fixed the SERVER_SIGNOFF notify handling on normal server
2855 not to save the history information for clients. Same was
2856 fixed earlier in remove_clients_by_server function, but not
2857 here. Affected file silcd/packet_receive.c.
2859 * Raised the default connection-retry count from 4 to 7 in
2860 server. Affected file silcd/server.h.
2862 * Cancel any possible reconnect timeouts when we start the
2863 key exchange. Affected file silcd/server.c.
2865 * Do not reconnect on connection failure when SCONNECT was
2866 given. Affected files silcd/server.[ch].
2868 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2870 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2872 * Fixed the NICK command to always give the unformatted
2873 nickname to the one giving the NICK command. If unformatted
2874 nickname is cached already it will be formatted and the
2875 local entry will always get the unformatted nickname.
2876 Affected file lib/silcclient/idlist.c.
2878 * Fixed some double frees from client library commands.
2879 Affected file is lib/silcclient/command.c.
2881 * Fixed CUMODE command in server to assure that no one can
2882 change founder's mode than the founder itself, there was a
2883 little bug. Affected file silcd/command.c.
2885 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2887 * Removed the SilcClientCommandDestructor from the client
2888 libary, it is not needed anymore. Affected files are
2889 lib/silcclient/silcapi.h, command[_reply].[ch],
2890 client_notify, idlist.c.
2892 * Fixed GETKEY command to first resolve client, and then
2893 resolve the server only if the client was not found, instead
2894 of resolving both at the same time. Affected file is
2895 lib/silcclient/command.c.
2897 * Added silc_client_start_key_exchange_cb and lookup the
2898 remote hostname and IP address before starting the key
2899 exchange with server. The affected file is
2900 lib/silcclient/client.c.
2902 * The server's public key is now saved using the IP address
2903 of the server and not the servername for the filename.
2904 The hostname public key filename is checked as an fall back
2905 method if the IP address based filename is not found.
2907 Fixed the GETKEY command to save the fetched server key
2908 in correct filename.
2910 Print the remote server's hostname now when new key is
2911 received during connection process. Affected file is
2912 irssi/src/silc/core/client_ops.c.
2914 * Return always our own public key to the client if it asks
2915 for it with GETKEY command. Affected file silcd/command.c.
2917 * Removed the use_auto_addr variable from default config
2918 file since it was in wrong section. Affected file is
2921 * Fixed TOPIC_CHANGE notification to not route it when it
2922 was sent using silc_server_send_notify_to_channel function.
2923 Affected file silcd/command.c.
2925 * Fixed silc_server_send_notify_kicked to send the kicker's
2926 Client ID also, it was missing. Affected files are
2927 silcd/command.c, silcd/packet_send.[ch].
2929 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2931 * Do not save client history information in SERVER_SIGNOFF.
2932 Fixes the bug in normal server that it does not detect
2933 the client becoming valid after the server becomes back
2934 online. Affected file silcd/server_util.c.
2936 * Added `sock_error' field into the SilcSocketConnection
2937 context. When error occurs during socket operation (read
2938 or write) the error is saved. Added also new function
2939 silc_socket_get_error to return human readable socket error
2940 message. Affected files are lib/silcutil/silcsockconn.[ch],
2941 lib/silcutil/unix/silcunixsockconn.c, and
2942 lib/silcutil/win32/silcwin32sockconn.c.
2944 * The server now prints the socket error message in the
2945 signoff for client. Affected file silcd/server.c.
2947 * Fixed the `created' channel information sending from router
2948 to server in JOIN command. Checks now whether the channel
2949 really was created or not and set it according that.
2951 Fixed the JOIN command to use the client entry's current
2952 ID during the joining procedure instead of the one it sent
2953 in the command (it is checked though), since it can change
2954 between the packet processing and command processing, and
2955 would just case unnecessary pain in the client end. Affected
2956 file silcd/command.c.
2958 * Fixed a channel key payload sending to use correct channel
2959 ID when the server was forced to change the channel's ID by
2960 router. Router sent the key payload with the old Channel ID.
2961 Affected file silcd/packet_receive.c.
2963 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2965 * Call silc_server_save_channel_key only if the key payload
2966 was provided in the JOIN command's command reply. Affected
2967 file silcd/command_reply.c.
2969 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2971 * Fixed silc_mp_sizeinbase to return the value correctly with
2972 MPI. Affected file lib/silcmath/mp_mpi.c.
2974 * Fixed the stop_server signal to correctly stop the scheduler
2975 and gracefully stop the server when SIGTERM or SIGINT signals
2976 are received. Affected file silcd/silcd.c.
2978 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2980 * Simple handling of TERM and HUP signals. Also added some log
2981 flushing call around. Affected file is
2984 * Fixed small bugs in silclog.c. Now buffering output will take
2985 effect after 10 seconds since startup: This will ensure that
2986 no important startup messages are lost. Also output redirection
2987 will preserve original format ([Date] [Type] message).
2988 Affected file is lib/silcutil/silclog.c.
2990 * Added two options to the config file, in the logging section:
2991 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2992 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2994 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2996 * Do not print the warning about log files not being initialized
2997 more than once to avoid excess logging. Affected file is
2998 lib/silcutil/silclog.c.
3000 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
3001 the SIM copying in make install in Makefile.am.pre.
3003 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3005 * Rewritten silclog APIs. Globally interesting changes follows:
3006 silc_log_set_files() changed to silc_log_set_file().
3007 silc_log_set_callbacks() changed to silc_log_set_callback().
3008 ROBOdoc documented silclog header file.
3009 SilcLogCb now returns bool to wether inihibit the default
3010 handler or not (to keep the old behaviour return always TRUE).
3011 The new APIs should also fix the problem of the
3012 silcd_error.log file that was written in the current directory.
3015 Log files streams will remain opened after silc_log_set_file()
3016 call, means less CPU usage notably on high traffic servers.
3017 File streams are now full buffered, and flushed to the disk
3018 every 5 minutes, lesses HD activity and CPU usage.
3019 Messages can be redirected, allowing admins to configure
3020 one single logfile for all server messages.
3021 the silc_log_quick global variable to activate fast-logging.
3022 Affected files lib/silcutil/silclog.[ch]
3024 * Changed some code to conform new silclog APIs. Affected
3025 files are doc/example_silcd.conf.in, silcd/server.c
3026 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
3029 * Fixed a memory leak that could occur in some situations.
3030 Affected file silcd/serverconfig.c.
3032 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3034 * Added the silc_client_del_client to remove the client from
3035 all channels as well. Affected file lib/silcclient/idlist.c.
3037 * Fixed the client library to correctly remove the client
3038 from all channels when the client entry is being destroyed.
3039 Affected file lib/silcclient/client_notify.c, command.c.
3041 * Added auto-nicking support to the client library. If the
3042 applicatio now sets client->nickname it will be sent to the
3043 server after connecting by the library. This way for example
3044 SILCNICK (or IRCNICK) environment variables will have effect
3045 and always change the nickname automatically to whatever
3046 it is wanted. Affected file lib/silcclient/client.[ch].
3048 * Renamed silc_server_command_bad_chars to the
3049 silc_server_name_bad_chars and moved it to the
3050 silcd/server_util.[ch]. Added also new function
3051 silc_server_name_modify_bad to return nickname that
3052 includes bad characters as new nickname without those
3053 bad characters. This check and modify is now used in
3054 silc_server_new_client when the username is initially set
3055 as nickname, so it must be checked to be valid nickname.
3056 Affected file silcd/packet_receive.c.
3058 * The nickname length is now taken from the packet for real
3059 and not trusted to strlen() since it clearly can return
3060 wrong length for nickname including bad characters. This
3061 also applies to channel names. Affected file silcd/command.c.
3063 * Removed the lib/silcsilm/modules directory. Modules are now
3064 compiled into the lib/silcsim. Fixed the copying of the
3065 modules to follow symbolic links in Makefile.am.pre.
3067 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3069 * Fixed silc_string_regexify list creation. Fixes bugs with
3070 BAN and INVITE commands in server. The affected file is
3071 lib/silcutil/unix/silcunixutil.c.
3073 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3075 * Removed the command destructor entirely from the server's
3076 command and command reply routines. It is not needed, and
3077 its usage was buggy and caused crashes. Affected files are
3078 silcd/command[_reply].[ch].
3080 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3082 * Cancel protocol and NULL sock->protocol if timeout
3083 occurred during protocol. Affected file silcd/server.c.
3085 * Cancel protocol timeouts always before calling the final
3086 callback, to assure that after final callback is called
3087 no other state will be called for the protocol anymore.
3088 Affected file silcd/protocol.c.
3090 * Print error log if incoming connection configuration could
3091 not be found. Affected file silcd/server.c.
3093 * Fixed JOIN command to correctly save the founder mode
3094 to the client on normal SILC server, when the channel
3095 was created by the router. Affected file silcd/command.c.
3097 * Fixed LIST command (hopefully) to send correct reply
3098 packets. Affected file silcd/command.c.
3100 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3102 * The silc_packet_receive_process now returns FALSE if the
3103 read data was invalid packet, and TRUE if it was ok.
3105 The server now checks that if unauthenticated connection
3106 sends data and its processing fails the server will close
3107 the connection since it could be a malicious flooder.
3109 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
3111 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3113 * Make sure the warning about error opening a log file is
3114 printed only once and not everytime it fails (produces
3115 too much useless log). Affected file lib/silcutil/silclog.c.
3117 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3119 * Made the silc_server_daemonise() function more readable.
3120 Affected file silcd/server.c.
3122 * Pid file is now optional, the user may comment it out from
3123 the config file. Removed define SILC_SERVER_PID_FILE, we
3124 don't need a default any longer. Affected file
3125 configure.in.pre, lib/Makefile.am.pre.
3127 * Make some use of the pid file. The server now dies at startup
3128 if it detects a valid pid file on his path. The server would
3129 die anyway in this circumstance, because of the bind() failure.
3130 Affected file silcd/silcd.c.
3132 * No longer compiling lib/dotconf.
3134 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3136 * Fixed JOIN command parsing not to crash. Affected file
3137 lib/silcclient/command.c.
3139 * Fied the NICK_CHANGE notify to add the new client entry
3140 even it is resolved. This removes an <[unknown]> nick
3141 thingy bug in the client. Affected file is
3142 lib/silcclient/client_notify.c.
3144 * Do not try to allocate 0 bytes (efence does not like it)
3145 in lib/silccore/silccomand.c when encoding payload.
3147 * Do not take IRCNICK as nickname in Irssi SILC client since
3148 it is not possible to set nickname before hand connecting
3149 the server (TODO has an entry about adding auto-nicking
3152 * Changed the silc_server_command_pending to check whether
3153 there already exists an pending entry with the specified
3154 command, command identifier and pending callback. This is
3155 to fix IDENTIFY and WHOIS related crashes that may register
3156 multiple pending commands with same identifier. Affected
3157 file silcd/command.c.
3159 * Fixed the server to reconnect to the router even if it
3160 was already reconnecting and EOF was received. This to
3161 fix a possibility that the server wouldn't ever try to
3162 auto-reconnect to the router. Affected file silcd/server.c.
3164 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3166 * Fixed the server's password authentication to use the
3167 length of the locally saved password, and not the one
3168 sent in the packet. Affected file silcd/protocol.c.
3170 * Fixed same password authentication problem in the
3171 Authentication Payload handling routines in
3172 lib/silccore/silcauth.c.
3174 * Yet another password authentication problem fixed with
3175 channel password handling in silcd/command.c.
3177 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3179 * If first character of string in silc_parse_userfqdn is '@'
3180 then do not parse it. Affected file is
3181 lib/silcutil/silcutil.c.
3183 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3185 * Fixed minor bug in IDENTIFY command reply sending, which
3186 caused various weird problems during JOIN when it was
3187 resolving names for users. Affected file silcd/command.c.
3189 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3191 * Fixed the IDENTIFY command reply sending to chech better valid
3192 clients. It was possible to send incomplete list of replies.
3193 Affected file silcd/command.c.
3195 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3197 * Added silc_client_command[s]_[un]register functions now to
3198 dynamically register the commands in client library. Removed
3199 the static table of commands. This allows the client library
3200 to call commands without causing the application to know about
3201 what commands library has called.
3203 Removed the INFO command reply kludge to detect when the command
3204 was called by library. Now library use its own command reply
3205 function for INFO command.
3207 Added function silc_client_command_call to call a command.
3208 Application can use it to call command, not access the structure
3211 Now all commands that are sent by the client library (not
3212 explicitly sent by application) use own command reply functions.
3214 Affected files around lib/silcclient/ and in
3215 irssi/src/silc/core/.
3217 * Fixed the WHOIS command reply sending to chech better valid
3218 clients. It was possible to send incomplete list of replies.
3220 Fixed the WHOIS and IDENTIFY to send the request to router
3221 if normal server did not do it and did not find any results.
3223 Affected file silcd/command.c.
3225 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3227 * Moved the internal data from SilcClient context into its
3228 own file, not accesible to application. Affected files
3229 lib/silcclient/client.h and lib/silcclient/client_internal.h,
3230 and other files in client library.
3232 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3234 * Added doc/examples installation target in Makefile.am.pre.
3237 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3239 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
3240 commands the found client entry will be removed from the
3241 cache, after notifying application about the error. Affected
3242 file lib/silcclient/command_reply.c.
3244 * Changed the /MSG to check for exact nickname user gave, and
3245 not let `nick' match `nick@host' if it is only one found. Now,
3246 user must type the exact nickname (like nick@host2) even if
3247 there are no more than one same nicks found. This is to avoid
3248 a possibility of sending nickname to wrong nickname since
3249 `nick' could match `nick@host'. Affected file is
3250 irssi/src/core/silc-servers.c.
3252 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3254 * Do not print "you are now server operator" or similar when
3255 giving /away command. Affected files are
3256 irssi/src/silc/core/client_ops.c, silc-servers.h.
3258 * Made the silc_server_command_pending_error_check to send
3259 the same command reply payload it received back to the
3260 original sender of the command. This way all arguments
3261 that was received by the server will be received by the
3262 client too. Affected file silcd/command.c.
3264 * Added the silc_idcache_add to return the created cache entry
3265 to a pointer. Affected file lib/silccore/silcidcache.[ch].
3267 * Add global clients to expire if they are not on any channel.
3268 This is because normal server will never know if they signoff
3269 if they are not on any channel. The cache expiry will take
3270 case of these entries. This is done by normal servers only.
3271 The affected files are silcd/command_reply.c,
3272 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
3274 * If server receives invalid ID notification for WHOIS or
3275 IDENTIFY and the ID exists in the lists, it is removed.
3276 Affected file silcd/command_reply.c.
3278 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
3279 in client then client entry that it matches is searched and
3280 the nickname is printed on the screen for user. Affected
3281 file irssi/src/silc/core/client_ops.c.
3283 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3285 * Use cache entry expire time in the LIST command reply to
3286 purge old entries from the cache after the LIST command
3287 reply has been received. This way we don't have non-existent
3288 entries in the cache for too long. Affected file is
3289 silcd/command_reply.c.
3291 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3293 * If we are normal server, and we've not resolved client info
3294 in WHOIS or IDENTIFY from router, and it is global client,
3295 we'll check whether it is on some channel. If it is not
3296 then we cannot be sure about its validity and will resolve it
3297 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
3298 file silcd/command.c.
3300 * Search channel by name (if possible) rather than by ID
3301 in IDENTIFY command's command reply. Affected file is
3302 silcd/command_reply.c.
3304 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3306 * Distribute to the channel passphrase in CMODE_CHANGE notify.
3307 Updated specs and implemented it. Affected file silcd/command.c,
3308 silcd/packet_send.c and silcd/packet_receive.c.
3310 * Implemented the <founder auth> payload handling in the JOIN
3311 command. If provided all conditions for channel joining
3312 except requirement to provide correct passphrase can be
3313 overrided by the channel founder. Updated the protocol specs.
3314 Affected file silcd/command.c.
3316 Added support for founder auth in JOIN command in client
3317 library. Fixed the parsing of the JOIN command now to support
3318 all options as they should be. The affected file is
3319 lib/silcclient/command.c.
3321 * Optimized the WHOIS and IDENTIFY commands to send the request
3322 to router only if it includes nicknames or other names. If
3323 they include only IDs then check the local cache first before
3324 routing. Affected file is silcd/command.c.
3326 * Added channels topic announcements. Affected file is
3327 silcd/packet_receive.c and silcd/server.c.
3329 * Fixed the silc_server_send_notify_topic_set to really destine
3330 the packet to channel. Affected file silcd/packet_send.c.
3332 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
3333 library. Affected file lib/silcclient/client_notify.c.
3335 * Added UMODE announcements. Affected file silcd/server.c.
3337 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3339 * Memory leak fixes in:
3341 lib/silcutil/silcsockconn.c
3342 lib/silcske/silcske.c
3343 lib/silcske/groups.c
3345 lib/silccrypt/silcpkcs.c
3346 lib/silccore/silccommand.c
3347 lib/silccore/silcidcache.c
3352 * ROBOdoc documented the lib/silcske/groups.h file and a
3353 bit changed the interface for better.
3355 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3357 * Update the client entry context in the ID cache after
3358 nick change. Affected file lib/silcclient/command.c.
3359 Fixes the CUMODE command when regaining founder privileges,
3360 and a little WHOIS problem.
3362 * Fixed silc_net_gethostbyname to correctly call the
3363 inet_ntop. Affected file lib/silcutil/silcnet.c.
3365 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3367 * Added IPv6 support checking to the configure.in.pre, added
3368 also --enable-ipv6 option to override the check. Affected
3369 file configure.in.pre.
3371 * The silc_thread_create now calls the start function
3372 directly if threads support is not compiled in. Removes
3373 ugly #ifdef's from generic code. Affected files are
3374 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
3376 * Added silc_net_gethostby[name/addr]_async to asynchronously
3377 resolve. Affected files are lib/silcutil/silcnet.[ch].
3379 * Added support for rendering IPv6 based server, client and
3380 channel IDs. Affected file lib/silcutil/silcutil.c.
3382 * Added support for creating IPv6 based server IDs. Affected
3383 file is silcd/serverid.c.
3385 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3387 * Added silc_net_gethostby[addr/name] into the
3388 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
3389 routines. Added silc_net_is_ip[4/6]. Affected file is
3390 lib/silcutil/unix/silcunixnet.c. All routines that take
3391 address as argument now supports both IPv4 and IPv6 addresses.
3393 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3395 * Fixed LIST command reply sending in server. Affected file
3398 * Server now sends the kicker's client ID in the KICK notify
3399 to the kicked client. Affected file silcd/command.c.
3401 * The client library now parses the kickers client ID and
3402 UI displays it. Affected files lib/silcclient/client_notify.c
3403 and irssi/src/silc/core/silc-channels.c, module-formats.c.
3405 * Made all payload parsing function prototypes consistent.
3406 They all take now const unsigned char * and uint32 pair as
3407 the payload data instead of SilcBuffer. Changes all around
3408 the source tree. Other unsigned char* -> const unsigned char*
3409 changes around the tree as well.
3411 * Optimized SFTP client and server packet sending not to
3412 allocate new buffer for each packet but to recycle the
3413 first allocated buffer. Affected files are
3414 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
3416 * Optimized the SFTP client to use SilcList instead of
3417 SilcDList for requests, because it is faster. Affected file
3418 is lib/silcsftp/sftp_client.c.
3420 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
3421 into lib/silccore/silcid.[ch].
3423 Renamed silcpayload.[ch] into silcargument.[ch].
3425 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3427 * If client entry is deleted with active key agreement
3428 session, abort the session.
3430 The silc_client_abort_key_agreement now calls the completion
3431 callback with new SILC_KEY_AGREEMENT_ABORTED status.
3433 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
3436 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3438 * Don't use __restrict in older GCC's. Affected file is
3439 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
3441 * silc_net_localhost now attempts to reverse lookup the
3442 IP/hostname. Affected file lib/silcutil/silcnet.c.
3444 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
3445 command. It can be used to gain founder privileges at
3446 the same time when joining the channel.
3448 Defined that the SILC_NOTIFY_TYPE_KICKED send the
3449 kicker's client ID as well. Updated protocol specs.
3451 Defined that the server must send SILC_COMMAND_IDENTIFY
3452 command reply with error status to client who sent
3453 private message with invalid client ID.
3455 Updated the protocol specification.
3457 * Added silc_server_send_command_reply to send any
3458 command reply. Affected file silcd/packet_send.[ch].
3460 * Added silc_id_payload_encode_data to encode ID payload
3461 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
3463 * The server now send IDENTIFY command reply with error
3464 status if client ID in private message is invalid. Affected
3465 file silcd/packet_receive.c.
3467 * Save the server key file with server's IP address in
3468 the filename instead of hostname. The affected file is
3469 irssi/src/silc/core/client_ops.c.
3471 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3473 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
3476 * Added libtool support for compiling shared objects in
3477 lib/silcsim. Affected file configure.in.pre and
3478 lib/silcsim/Makefile.am. Original patch by cras.
3480 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3482 * Pid file configuration, and server's config file fixes
3483 patch by toma. Updated CREDITS file.
3485 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3487 * Fixed silc_client_channel_message to not try to decrypt
3488 the message twice if it resolved the destination client
3489 information. This could cause of dropping one channel
3490 message. Affected file lib/silcclient/client_channel.c.
3492 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3494 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3495 lib/silcclient/client.c. This function is used when the SILC
3496 Client is run under some other scheduler, or event loop or
3497 main loop. On GUI applications, for example this may be
3498 desired to used to run the client under the GUI application's
3499 main loop. Typically the GUI application would register an
3500 idle task that calls this function multiple times in a second
3501 to quickly process the SILC specific data.
3503 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3505 * Fixed silc_server_drop() for dropping the supplementary
3506 groups as well, this could cause a security hole on some
3509 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3511 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
3514 * Write PID file after dropping privileges. Added -F option
3515 to run server on foreground. A patch by debolaz.
3516 Affected files silcd/server.c, silcd/silcd.c.
3518 * Fixed MOTD to return the MOTD file server name. Affected
3519 file silcd/command.c.
3521 * Added INFO command reply handling to the Irssi SILC Client.
3522 Affected file irssi/src/silc/core/client_ops.c.
3524 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3526 * Fixed the silc_idcache_list_* routines to really support
3527 the dynamic list. Fixes a crash. Affected file is
3528 lib/silccore/silcidcache.c.
3530 * Fixed the LIST command reply to really call LIST command's
3531 pending callbacks. Affected file silcd/command_reply.c.
3533 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3535 * Update conn->local_entry->nickname after giving NICK
3536 command. Affected file lib/silcclient/command.c.
3538 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3540 * Added the [pid] option to the silcd configuration file
3542 Affected files: serverconfig.[ch] and silcd.c
3544 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3546 * Save fingerprint in WHOIS command reply in server.
3547 Affected file silcd/command_reply.c.
3549 * Fixed NICK commands pending callback registration.
3550 Affected file lib/silcclient/command.c.
3552 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3554 * Use ++server->cmd_ident when sending commands in server,
3555 instead of random number. Affected file silcd/command.c.
3557 * Fixed GETKEY command reply to call actually GETKEY pending
3558 command callbacks. Affected file silcd/command_reply.c.
3560 * A bit stricter check for nicknames. Check for same nickname
3561 in NICK command also. Affected file silcd/command.c.
3563 * Do not call INFO command everytime client ID changes, only
3564 during first connecting. Affected file lib/silcclient/client.c.
3566 * Set the new nickname only after successful command reply for
3567 NICK command is returned by server. Affected file
3568 lib/silcclient/command.c.
3570 * Remove nicknames from nicklist during server_signoff notify.
3571 Should fix /NAMES bit more. The affected file is
3572 irssi/src/silc/core/silc-channels.c.
3574 * Added `fingerprint' field to the SilcIDListData in the
3575 silcd/idlist.h to hold the fingerprint of the client's
3578 Send the fingerprint of the client's public key in WHOIS
3581 Affected files silcd/command.c, and silcd/idlist.[ch].
3583 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3584 create fingerprint from given data.
3586 * Show the fingerprint of the client's public key in WHOIS.
3587 Affected files irssi/src/module-formats.[ch] and
3588 irssi/src/silc/core/client_ops.c.
3590 * Format the multiple same nicknames also during JOIN and
3591 NICK_CHANGE notifys. Affected file is
3592 lib/silcclient/client_notify.c.
3594 * Do not print error on screen for invalid private message
3595 payload since it can come if someone is sending private
3596 messages with wrong key. Affected file
3597 lib/silccore/silcprivate.c.
3599 * Fixed multiple concurrent /PING crash. Affected file
3600 lib/silcclient/command.c.
3602 * Changed the wrong ID encoding. All IP addresses must be
3603 in MSB first order in encoded format. They were encoded
3604 wrong and was in LSB format. Affected files are
3605 silcd/serverid.c, lib/silcutil/silcutil.c.
3607 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3609 * Call the `connect' client operation through the scheduler
3610 in case of error. Affected file lib/silcclient/client.c.
3612 * Call the `failure' client operation even if the error
3613 occurred locally during a protocol. Affected file is
3614 lib/silcclient/protocol.c.
3616 * Added support of sending LIST command to router from normal
3617 server. This way normal server can get list of all channels
3618 in the network too. Fixed the channel list sending in the
3619 server too. Affected files are silcd/command.c, and
3620 silcd/command_reply.[ch].
3622 * Added silc_server_update_channels_by_server and
3623 silc_server_remove_channels_by_server. They are used during
3624 disconnection of primary router and in backup router protocol.
3625 Affected file silcd/server_util.[ch], silcd/server.c and
3626 silcd/server_backup.c.
3628 * Fixed channel adding to global list in IDENTIFY command
3629 reply in server. Affected file silcd/command_reply.c.
3631 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3633 * If the incoming packet type is REKEY or REKEY_DONE process
3634 that packet always synchronously. Fixes yet another MAC
3635 failed error on slow (dialup) connections. Affected file
3636 lib/silcclient/client.c and silcd/server.c.
3638 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3640 * Call check_version SKE callback for initiator too. Affected
3641 file lib/silcske/silcske.c.
3643 * Implemented fix for security hole found in the SKE that was
3644 fixed in the specification few days back; the initiator's
3645 public key is now added to the HASH value computation.
3646 Added backwards support for the old way of doing it too, for
3647 old clients and old servers. Affected file is
3648 lib/silcske/silcske.c.
3650 * Enabled mutual authentication by default in SKE. If initiator
3651 is not providing mutual authentication the responder will
3652 force it. This will provide the proof of posession of the
3653 private key for responder. The affected files are
3654 lib/silcclient/protocol.c and silcd/protocol.c.
3656 * Do not cache anymore the server's public key during SKE.
3657 We do mutual authentication so the proof of posession of
3658 private key is done, and if the server is authenticated in
3659 conn auth protocol with public key we must have the public
3660 key already. Affected file silcd/protocol.c.
3662 * Added new global debug variable: silc_debug_hexdump. If
3663 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3664 file lib/silcutil/silclog.[ch].
3666 * Fixed compilation warning due to char * -> const char *.
3667 Affected files lib/silcutil/silcnet.h, and
3668 lib/silccore/silcauth.[ch].
3670 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3672 * Fixed CMODE command when new channel key was created. If
3673 the creation failed the old key was removed. Next time giving
3674 same command would crash the server since the old key was
3675 freed already. Affected file silcd/command.c.
3677 * Fixed the silc_server_announce_get_channels to not crash
3678 on reconnect. Affected file silcd/server.c.
3680 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3682 * Added silc_log_set_debug_string function to set a regex
3683 string to match for debug output. Only the function names,
3684 or filenames matching the given debug string is actually
3685 printed. This way it is possible to filter out those debug
3686 strings that user is not interested in.
3688 Fixed a bug in silc_string_regexify.
3690 Affected files lib/silcutil/silclog.[ch], and
3691 lib/silcutil/unix/silcunixutil.c.
3693 * Changed the -d options in both server and Irssi SILC client
3694 to take the debug string as argument. Affected files
3695 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3697 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3699 * Added silc_hash_babbleprint to create a Bubble Babble
3700 Encoded fingerprint. The encoding is developed by Antti
3701 Huima (draft-huima-babble-01.txt), and it creates human
3702 readable strings out of binary data. Affected file
3703 lib/silccrypt/silchash.[ch].
3705 * Print the babble print now in addition of fingerprint as well
3706 in Irssi SILC client. Affected files are
3707 irssi/src/fe-common/silc/module-formats.[ch],
3708 irssi/src/fe-common/silc/core/client_ops.c.
3710 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3712 * Fixed a security problem found in SKE. The initiator's
3713 public key too is now added to the HASH hash value creation
3714 which is signed by the responder to create the SIGN value.
3715 This will prevent anyone in the middle to lie to the responder
3716 about the initiator's public key. If this is done now, the
3717 man in the middle will get caught. Updated the protocol
3720 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3722 * Better installation directory handling. Configure module
3723 paths and other paths automatically to example_silc* files
3724 in doc/. A patch by toma.
3726 * Fixed compiler warning from MPI library, and from SILC RNG.
3729 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3730 It can be configured with ./configure. A patch by toma.
3732 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3734 * Find correct make to use in prepare-clean. A patch by
3735 toma. Affected file prepare-clean.
3737 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3739 * Added irssi variables use_auto_addr, auto_bind_ip,
3740 auto_bind_port and auto_public_ip.
3742 * Changed the interface for silc_client_send_key_agreement
3743 in lib/silcclient/silcapi.h
3747 irssi/src/silc/core/silc-core.c
3749 lib/silcclient/silcapi.h
3750 irssi/src/silc/core/silc-channels.c
3751 lib/silcclient/client_keyagr.c
3754 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3756 * Added silc_pkcs_public_key_compare to compare two
3757 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3759 * Check that the client who set the founder mode on the
3760 channel is the same client that is giving the founder
3761 mode to itself. It is done by comparing the saved public
3762 key (it is saved even in the authentication is passphrase).
3763 Affected file silcd/command.c.
3765 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3767 * Do not process packet for disconnected socket connection.
3768 Affected file lib/silccore/silcpacket.c.
3770 * Process the DISCONNECT packet through scheduler in the
3771 client library. Affected file lib/silcclient/client.c.
3773 * Fixed the silc_client_packet_parse to not to increase
3774 the packet sequence number if the conn->sock and the
3775 current socket connection is not same. This can happen
3776 for example during key agreement when the conn includes
3777 multiple socket connections (listeners). Affected file
3778 lib/silcclient/client.c.
3780 * The sender of the file transfer request now provides also
3781 the pointer (listener) for the key exchange protocol. If
3782 the listener cannot be created then it sends empty key
3783 agreement and lets the receiver provide the listener.
3785 Added `local_ip' and `local_port' arguments to the
3786 silc_client_file_send. If they are provided they are used,
3787 if not then it will attempt to find local IP address, if
3788 not found or bind fails then the remote client will provide
3791 Affected files are lib/silcclient/client_ftp.c and
3792 lib/silcclient/silcapi.h.
3794 * Extended the FILE SEND command to support defining the
3795 local IP and port for key exchange listener. They are
3796 optional. Affected file irssi/src/silc/core/silc-servers.c.
3798 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3800 * Defined to WHOIS command reply the sending of fingerprint
3801 of the client's public key (if the proof of posession of the
3802 corresponding private key is verified by the server).
3803 Updated to the protocol specification.
3805 * Added support of receiving the client's public key's
3806 fingerprint in command reply in client library. Affected
3807 file is lib/silcclient/command_reply.c, and
3808 lib/silcclient/idlist.[ch].
3810 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3812 * Do not send over 128 chars long nickname to the server
3813 in NICK command. Affected file lib/silcclient/command.c.
3815 * Do not send over 256 chars long channel names to the server
3816 in JOIN command. Affected file lib/silcclient/command.c.
3818 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3820 * Assure that silc_server_close_connection cannot be called
3821 twice for same socket context. Affected file is
3824 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3826 * Send error message to application if opening file for
3827 writing during file transfer fails. Affected file is
3828 lib/silcclient/client_ftp.c.
3830 Remove all file transfer sessions for a client that we're
3831 removing from ID cache.
3833 Affected file is lib/silcclient/client_ftp.c.
3835 * Fixed silc_net_addr2bin to return correct address. Affected
3836 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3838 * Fixed file transfer session removing on signoff notify.
3839 Affected file irssi/src/silc/core/silc-servers.c.
3841 * Added the SilcClientFileError to be returned in the monitor
3842 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3843 Affected file lib/silcclient/silcapi.h.
3845 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3847 * Fixed a crash in silc_client_ftp_free_sessions and
3848 silc_client_ftp_session_free_client. Affected file
3849 lib/silcclient/client_ftp.c.
3851 * Added `disabled' field in the SilcChannelEntry in the server
3852 to indicate if the server entry is disabled. Affected file

3862 * Fixed a crash in client resolving in client_prvmsg.c in
3863 client library. Affected file lib/silcclient/client_prvmsg.c.
3865 * Do not actually remove the client directly from ID cache
3866 during SERVER_SIGNOFF, but invalidate it. This way we
3867 preserve the WHOWAS info for the client. Affected file
3868 silcd/server_util.c.
3870 * Fixed SERVER_SIGNOFF notify handling in the server. The
3871 server is now able to process incoming SERVER_SIGNOFF notify
3872 for a server that it doesn't even know about. It will remove
3873 the clients provided in the notify. Affected file
3874 silcd/packet_receive.c.
3876 * Check for partial packet in data queue after every packet that
3877 was found from the queue. Return and wait for more data if
3878 there is partial data in queue. Affected file is
3879 lib/silccore/silcpacket.c.
3881 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3883 * Added SilcClietFileError enum to indicate error in
3884 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3885 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3886 Affected files lib/silcclient/silcapi.h and
3887 lib/silcclient/client_ftp.c.
3889 * Check that newsize in silc_buffer_realloc is larger than
3890 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3892 * Added better monitor of file transfers. It now monitors
3893 key agreement protocol during the file transfer too. Added
3894 error reporting too. Affected files
3895 irssi/src/silc/core/silc-servers.c,
3896 irssi/src/fe-common/silc/module-formats.[ch].
3898 * Wrote a help file for FILE command.
3900 * Added silc_rng_global_get_byte_fast to get not-so-secure
3901 random data as fast as possible. Random data is read from
3902 /dev/urandom if available and from the SILC RNG if not
3903 available. It is used in padding generation. Affected file
3904 lib/silccrypt/silcrng.[ch].
3906 * All packets in client library are now processed synchronously.
3907 Optimized packet processing a lot. Affected file
3908 lib/silcclient/client.c.
3910 * All server connection packets are processing synchronously
3911 now in server, to optimize packet processing. Affected file
3914 * Include files are installed now only in Toolkit distribution
3915 if make install is given. Affected files: all Makefile.am's.
3917 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3919 * Assure that silc_client_notify_by_server_resolve does not
3920 resolve the client information multiple times. If it cannot
3921 be found by the first it cannot be found at all. Affected
3922 file lib/silcclient/client_notify.c.
3924 * Fixed WHOWAS command reply calling. Affected file
3925 lib/silcclient/command_reply.c.
3927 * Removed all references to silc_idlist_get_client from the
3928 Irssi SILC client since that call is internal call used by
3929 the library. The Irssi SILC client will use now client
3930 retrieval functions found in silcapi.h.
3932 * Fixed a bug in resolving nickname info before sending
3933 private message. It used freed memory. Affected file
3934 irssi/src/silc/core/silc-servers.c.
3936 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3938 * Assure my_channels statistics cannot go negative in server.
3939 Affected files silcd/server.c, silcd/server_util.c.
3941 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3943 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
3945 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

3955 * Added silc_net_localip to return local host's IP address.
3956 Affected file lib/silcutil/silcnet.[ch].
3958 * If key exchange or rekey protocol is active for a connection
3959 parse all packets syncronously since there might be packets
3960 in packet queue that we are not able to process without first
3961 processing packets before them. Affected file silcd/server,
3962 lib/silcclient/client.c.
3964 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3965 whether library should continue processing the packet.
3966 Affected file lib/silccore/silcpacket.h.
3968 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
3969 SilcSFTPMonitorData to SFTP server to monitor various
3970 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

3976 * Implemented the file transfer support for the client library.
3977 Added preliminary support for simple client to client one-file
3978 transmission. Affected file lib/silcclient/client_ftp.c,
3979 lib/silccilent/client.[ch].
3981 * Added new local command FILE to the Irssi SILC Client.
3982 It is used to perform the file transfer. It has subcommands
3983 SEND, RECEIVE, SHOW and CLOSE. Affected files
3984 irssi/src/silc/core/client_ops.c,
3985 irssi/src/silc/core/silc-server.[ch].
3987 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3989 * Relay the SILC_PACKET_FTP in the server. Affected files
3990 silcd/server.c and silcd/packet_receive.c.
3992 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3994 * Renamed silc_file_read and silc_file_write to functions

3997 lib/silcutil/silcutil.[ch].
3999 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4001 * Resolve the client info when received private message or
4002 channel message for a client which nickname we don't know.
4003 Affected files lib/silcclient/client_prvmsg.c and
4004 lib/silcclient/client_channel.c.
4006 * Do not crash in /KEY if client is not connected. Affected
4007 file irssi/src/silc/core/silc-channels.c.
4009 * Added SilcClientStatus field to the SilcClientEntry in the
4010 lib/silcclient/idlist.h.
4012 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
4013 is incomplete and is being resolved, it won't be resolved
4016 Make sure also that USERS command reply does not resolve
4017 twice information. Affected file is
4018 lib/silcclient/command_reply.c.
4020 Make sure that silc_client_get_clients_by_list does not
4021 resolve twice same information.
4023 * Check for valid client->id in the silc_server_free_client_data.
4024 Affected file silcd/server.c.
4026 * Fixed /GETKEY nick@server not to crash if the server entry
4027 is not found. Affected file lib/silcclient/command.c.
4029 * Fixed the silc_server_check_cmode_rights to check the
4030 requested modes correctly. Affected file silcd/command.c.
4032 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4034 * Better checks for non-printable chars in nick added.
4035 Affected file silcd/command.c.
4037 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4039 * Call the silc_server_udpate_servers_by_server in the
4040 primary router that comes back online in the backup resuming
4041 protocol. Otherwise it routes packets wrong. Affected file
4042 silcd/server_util.[ch], silcd/server_backup.c.
4044 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4046 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
4047 lib/silcutil/silcbuffmt.[ch].
4049 * Redefined the SILC packet header to include the padding
4050 length. Affected file lib/silccore/silcpacket.[ch].
4052 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
4053 length for maximum padding up to 128 bytes). Affected
4054 file lib/silccore/silcpacket.h.
4056 * Removed all backwards support for old 0.5.x MAC thingies.
4057 The SILC packet header change makes it impossible to be
4058 backwards compatible.
4060 * Send the ENDING packet with timeout in the backup resuming
4061 protocol. This is to assure that all routers has connected
4062 to the primary router. Affected file silcd/server_backup.c.
4064 * Changed the RNG to take the first IV from random data. It
4065 used to take it from zero actually. Changed the RNG also
4066 to use /dev/urandom during session. /dev/random is used
4067 in initialization. Affected file lib/silccrypt/silcrng.[ch].
4069 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4071 * Changed the SILC packet header to have the first two bytes
4072 (the packet length) encrypted. Affected files aroung the
4073 code tree, lib/silccore/silcpacket.[ch]. Removed the
4074 SilcPacketCheckDecrypt callback. It is not needed anymore
4075 since the silc_packet_receive_process will determine now
4076 whether the packet is normal or special.
4078 * Implemented the unidirectional MAC keys. Affected files
4079 lib/silcske/silcske.c, silcd/protocol.c and
4080 lib/silcclient/protocol.c.
4082 * Implemented the packet sequence number to the MAC computation.
4083 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
4084 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
4085 lib/silcclient/protocol.c.
4087 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4089 * Allow backup router to announce servers. All servers
4090 announced by backup router are added to the global list
4091 automatically. Update hte server's socket to our primary
4092 router also when backup router announces a server.
4093 Affected file silcd/packet_receive.c.
4095 * Do not update the client->router in the function
4096 silc_server_udpate_clients_by_server if the client is on
4097 global list. We might fail to find any specific server
4098 for locally connected clients and local cell clients. They
4099 should still use the `from' and not `to' as client->router.
4100 This fixes backup router resuming protocol. Affected file
4101 silcd/server_util.c.
4103 * Decrease channel statistics count only if the channel
4104 deletion worked. Affected files are silcd/server.c and
4105 silcd/server_util.c.
4107 * Added silc_server_update_servers_by_server to update origin
4108 of all server entries. Used during backup router protocol.
4109 Affected files silcd/server_util.[ch], silcd/server.c. and
4110 silcd/backup_router.c.
4112 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
4113 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
4114 silc_hmac_get_hash and silc_hmac_get_name. Affected file
4115 lib/silccrypt/silchmac.c.
4117 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4119 * Assure that router cannot reroute the same channel message
4120 to the sender. Affected file silcd/packet_receive.c.
4122 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4124 * Made better checks that the channel message is not sent
4125 to the router it came from. Affected file is
4126 silcd/packet_send.c. Fixed memory leak too.
4128 * Announce informations for incoming router connection, but
4129 only after checking if it is replaced by backup router.
4130 Affected file silcd/packet_receive.c.
4132 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4134 * Fixed the backup resuming protocol to work in multiple
4135 router environment. Affected file silcd/server_backup.c.
4137 * Route packet only to one router in the function
4138 silc_server_packet_send_to_channel. Affected file is
4139 silcd/packet_send.c.
4141 * Fixed silc_server_send_notify_dest to set the broadcast
4142 flag. Fixed the silc_server_send_notify_topic to actually
4143 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
4144 Affected file silcd/packet_send.c.
4146 * Changed the SFTP Filesystem interface. Changed the
4147 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
4148 the filesystem operation function. The SilcSFTPFilesystem
4149 is now a context that is allocated by all filesystem allocation
4150 functions and it already includes the operations structure
4151 and filesystem specific context. It is given as argument
4152 now to the silc_sftp_server_start. This made the interface
4153 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
4154 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
4156 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4158 * Changed the backup router adding and getting interfaces
4159 in the server. The router that will be replaced by the
4160 specified backup router is now sent as argument. Affected
4161 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
4164 * Added silc_net_addr2bin_ne to return the binary form of
4165 the IP address in network byte order. Affected files
4166 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
4168 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4170 * Check for existing server ID in silc_server_new_server
4171 and in silc_server_connect_to_router_final and remove the
4172 old entry if it exists. Affected file silcd/packet_receive.c,
4175 * Send the channel message always to only one router, either
4176 in upstream or downstream. Affected file is
4177 silcd/packet_send.c.
4179 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4181 * Wrote the definition of the backup resuming protocol to the
4182 protocol specification.
4184 * Removed one redundant channel key generation from normal
4185 server during joining procedure. Removed one redundant
4186 channel key sending from server to router during joining
4187 procedure. Affected file silcd/command.c.
4189 * Made minor bugfixes to the backup router resuming protocol.
4190 Affected file silcd/server_backup.c, server.c.
4192 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4194 * Added --disable-asm configuration option. Affected files
4195 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
4198 * Implemented the backup resuming protocol that is used to
4199 resume the primary router position in the cell after the
4200 primary router comes back online. Affected files
4201 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
4202 and silcd/server_util.[ch].
4204 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4206 * Sleep two (2) seconds after sending QUIT command to server.
4207 Affected file lib/silcclient/command.c.
4209 * Assure that if outgoing data buffer is pending do not force
4210 send any data. Affected file silcd/packet_send.c.
4212 * Assure that if outgoing data buffer is pending do not force
4213 send any data. Affected file lib/silcclient/client.c.
4215 * Implemented the backup router support when the primary router
4216 goes down. The servers and routers can now use the backup
4217 router as new primary router without loosing connectivity.
4219 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4221 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
4222 in the server to indicate disabled entry. All data read
4223 from the connection will be ignored and no data is sent
4224 for entry that is disabled. Affected files are
4225 silcd/idlist.h, silcd/server.c.
4227 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4229 * Created SFTP client and server test programs in the
4230 lib/silcsftp/tests directory.
4232 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4234 * Implemented memory filesystem (virtual filesystem) for
4235 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
4238 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4240 * Implemented the SFTP (SSH File Transfer Protocol) to the
4241 lib/silcsftp. It includes SFTP client and SFTP server
4244 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4246 * Moved lib/silccore/silcprotocol.[ch] to the
4247 lib/silcutil library.
4249 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
4250 take variable argument list pointer as argument. Affected
4251 file lib/silcutil/silcbuffmt.[ch].
4253 * Added silc_buffer_set function that is used to set data
4254 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
4255 Affected file lib/silcutil/silcbuffer.h.
4257 * Changed various routines in the core library to use the new
4258 silc_buffer_set instead of allocating new buffer only for
4261 * Added 64-bit value formatting and unformatting support to the
4262 silc_buffer_[un]format routines. Affected file is
4263 lib/silcutil/silcbuffmt.[ch].
4265 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
4266 to includes/bitmove.h.
4268 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4270 * Fixed channel user mode saving in client library. Affected
4271 file lib/silcclient/command[_reply].c.
4273 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4275 * Defined the file transfer to the SILC Protocol. Added
4276 new packet type SILC_PACKET_FTP and defined File Transfer
4277 Payload. The mandatory file transfer protocol is SFTP
4278 (SSH File Transfer Protocol). Affected file in addition
4279 of the internet draft is lib/silccore/silcpacket.h.
4281 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
4282 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
4283 is used as part of backup router protocol when the primary
4284 router of the cell is back online and wishes to resume
4285 the position as primary router.
4287 * Redefined the MAC generation keys in the protocol. The
4288 same key is not used anymore in both direction. Both
4289 direction will now use different keys for sending and
4290 receiving. This fixes a potential security flaw. This
4291 change causes incompatibilities in the protocol.
4293 * Redefined also the MAC computation from the packet.
4294 An packet sequence number is now added to the MAC
4295 computation. This prevents possible replay attacks against
4296 the protocol. This change too causes incompatibilities
4299 Added `sequence' field to the SilcPacketContext to hold
4300 the current sequence number for the packet.
4302 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4304 * Added `created' field to the SilcIDListData in the file
4305 silcd/idlist.h to indicate the time when the entry was
4308 * Added `created' field to the SilcChannelEntry too. Affected
4309 file silcd/idlist.h.
4311 * Added `creation_time' aguments to all the announcement functions
4312 in the server. If it is provided then only the entries that
4313 was created after the provided time frame are actually
4314 announced. Affected file silcd/server.[ch].
4316 * The protocol says that the Channel ID's IP address must be
4317 based on the router's IP address. Added check for this in
4318 the silc_server_new_channel when processing incoming New Channel
4319 Payload. Affected file silcd/packet_receive.c.
4321 * Print out the correct version with --version in SILC client.
4322 Affected file irssi/src/silc/core/silc-core.c.
4324 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4326 * Fixed WHOWAS command to check for completnes of the client
4327 entry always, not just when the command is coming from client.
4328 Affected file silcd/command.c.
4330 * Added new function silc_server_packet_queue_purge to purge the
4331 outgoing data queue to the network. After the function returns
4332 it is guaranteed that the outgoing packet queue is empty.
4333 Affected file silcd/packet_send.[ch].
4335 * Purge the outgoing packet queue in the rekey protocol's final
4336 callback to assure that all rekey packets go to the network
4337 before quitting the protocol. Affected file silcd/server.c.
4339 * Added silc_client_packet_queue_parse as similar function as
4340 in server to the client library. The affected file is
4341 lib/silcclient/client.c.
4343 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4345 * Splitted silcd/server.c and created silcd/server_util.[ch]
4346 for utility functions.
4348 * Added new socket flag SILC_SF_DISABLED to indicate that the
4349 connection is open but nothing can be sent to or received from
4350 the connection. Affected file lib/silcutil/silsockconn.[ch].
4351 The checking for disabled socket is checked in the low level
4352 silc_socket_write and silc_socket_read functions.
4354 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4356 * Allow only nicknames and channel names that fits into the
4357 7-bit unsigned char ASCII set. Affected file silcd/command.c.
4359 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4361 * When processing JOIN command reply in server check that if
4362 the channel exists in our global list we'll move it the local
4363 list. Affected file silcd/command_reply.c.
4365 * Fixed the check whether client is joined on the channel already
4366 in JOIN command. Affected file lib/silcclient/command.c.
4368 * Fixed the JOIN command reply to check whether the channel
4369 already exists. Affected file lib/silcclient/command_reply.c.
4371 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4373 * Added silc_ske_status_string to map the SKE error numbers
4374 to readable strings. The affected files are
4375 lib/silcske/silcske[_status].[ch].
4377 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4379 * Do not show the private channels on the WHOIS channel list
4380 as it is not allowed by the protocol. The affected file is
4383 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4385 * Assure that the packet length digged from the actual packet
4386 is something sensible in the silc_packet_decrypt_rest_special
4387 in lib/silccrypt/silcpacket.c.
4389 * Free and NULL the allocated pointer in silc_hmac_alloc if
4390 the HMAC allocation fails. The affected file is
4391 lib/silccrypt/silchmac.c.
4393 * Print the selected security properties to the log files in
4394 the server. Affected file silcd/protocol.c.
4396 * Add SKE's reference counter even if calling the completion
4397 callback manually. Otherwise it goes negative, although it
4398 does not cause any problems. The affected file is
4399 lib/silcske/silcske.c.
4401 * Remove the client entry with short timeout after giving the
4402 KILL command. Affected file lib/silcclient/command.c.
4404 * Fixed to send error reply in WHOIS and IDENTIFY commands in
4405 case all found clients are already disconnected (WHOWAS would
4406 found them) in the server. Affected file silcd/command.c.
4408 * Update the last_receive (time of last data received) to be
4409 updated only when received private or channel message so that
4410 the idle time showed in WHOIS makes more sense.
4412 * Added boolean field `valid' in to the SilcClientEntry in the
4413 client library to indicate whether the entry is valid or not.
4414 This fixes the nickname change bug on channel when changing
4415 the nickname to be same than the old (like nick to Nick) the
4416 nickname formatter doesn't set the new nick anymore to Nick@host.
4417 Affected file lib/silcclient/idlist.[ch].
4419 * Now actually fixed the nickname changing on disconnection.
4420 Added new function silc_change_nick to the Irssi SILC Client.
4421 Affected file irssi/src/silc/core/client_ops.c,
4422 irssi/src/silc/core/silc-nicklist.[ch].
4424 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4426 * Check that the public key exists in the GETKEY command before
4427 trying to encode it. Affected file silcd/command.c.
4429 * Print some notifications on received public keys with GETKEY
4430 command in the Irssi SILC Client. Affected files are
4431 irssi/src/fe-common/silc/module-formats.[ch],
4432 irssi/src/silc/core/client_ops.c.
4434 * Use IDENTIFY command to resolve the server information in the
4435 GETKEY command instead of INFO command. Affected file
4436 lib/silcclient/command.c.
4438 * All command reply functions in the client library now calls
4439 the pending command reply callbacks even if an error has
4440 occurred. The server has done this a long time and now it was
4441 time to move the client library to this as well. Now all
4442 errors can be delivered back to the pending command reply
4443 callbacks if necessary. Affected files are
4444 lib/silcclient/command[_reply].[ch].
4446 * Change the nickname on disconnection back to the username
4447 because in reconnect the server will enforce it to it anyway.
4448 Affected file irssi/src/silc/core/silc-servers.c.
4450 * Fixed a config file parsing bug in the Irssi SILC client.
4451 Affected file irssi/src/silc/core/clientconfig.c.
4453 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4455 * When printing the channel mode on JOIN, verify that the
4456 channel key and channel's HMAC are valid. Affected file
4457 irssi/src/silc/core/client_ops.c.
4459 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4461 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
4462 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
4463 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
4465 * Removed channel key rekey task deleting from the function
4466 silc_server_save_channel_key. Affected file silcd/server.c.
4467 Added explicit timeout task context instead that is used to
4468 delete the task if we are registering a new task before the
4469 new task has elapsed.
4471 * When channel key rekey occurs the client library now saves
4472 the old channel key for a short period of time (10 seconds) and
4473 is able to use it in case some is still sending channel
4474 messages encrypted with the old key after the rekey. Affected
4475 file lib/silcclient/[idlist.h|client_channel.c].
4477 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4479 * Added check to the silc_server_new_id_real to not accept
4480 new ID if it is the sender's own ID. Affected file is
4481 silcd/packet_receive.c.
4483 * Assure that we do not announce ourself or the one we've
4484 sending our announcements when we're router and are announcing
4485 servers to our primary router. Affected file silcd/server.c.
4487 * Fixed silc_server_command_identify_check_client to assemble
4488 correct WHOIS packet. It send corrupted WHOIS packet and
4489 caused problem with router to router connections. Affected
4490 file silcd/command.c.
4492 Fixed also silc_server_command_whois_check the same way
4493 as for the IDENTIFY command.
4495 * Added new SilcIDListStatus to the server in the SilcIDListData
4496 structure. The status now includes the current status of
4497 the entry (like registered, resolved etc.). Affected file
4498 silcd/idlist.[ch]. Defined a bunch of different status types
4499 as well. This replaced the old boolean registered field as well.
4501 Added resolve_cmd_ident field to the SilcClientEntry structure
4502 too so that if the entry is for example being resolved so
4503 another command may attach to the same pending command reply
4504 without requiring to resolve the same entry again. This concept
4505 should optimize the WHOIS and the IDENTIFY resolving under
4506 heavy load by taking away unnecessary resolving for entries
4507 that are being resolved already.
4509 Added support for adding multiple pending commands for one
4510 command idenfier. Affected file silcd/command[_reply].[ch].
4512 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4513 before deleting the data. Otherwise the hash table will have
4514 freed data in comparison functions. Affected file is
4515 silcd/command_reply.c.
4517 * Fixed silc_idlist_replace_client_id to add the new entry to
4518 the cache with NULL nickname. Otherwise there will be invalid
4519 memory as the nickname after the nickname is freed. Affected
4520 file silcd/packet_receive.c.
4522 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4523 saved into wrong slots because the previous number of entries
4524 was not taken into account. Affected file silcd/idlist.c.
4525 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4527 * If we are router and we receive JOIN notify to a channel that
4528 does not have any users then notified client is marked as the
4529 channel founder, as it is it. The affected file is
4530 silcd/packet_receive.c
4532 * Added to the extended hash table API's table_del_*ext functions
4533 the destructor as argument too, so that the caller can decide
4534 which destructor to use or whether to use destructor at all.
4535 Affected file lib/silcutil/silchashtable.[ch].
4537 * Fixed ID Cache purging. It actually deleted the entries from
4538 the hash table after the data was freed. The hash table ended
4539 up comparing freed memory. The affected file is
4540 lib/silccore/silcidcache.c.
4542 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4544 * Fixed Irssi SILC client's KILL command's HELP syntax.
4546 * The USERS command now resolves the detailed user information
4547 if the userinfo field is missing. Affected file is
4548 lib/silcclient/command_reply.c.
4550 * Do not print error in silc_file_read if the read file does
4551 not exist. Just silently return NULL. Affected file is
4552 lib/silcutil/silcutil.c.
4554 * Fixed the silc_log_output to not wine about NULL filename
4555 and to not create some bogus " " filename. Affected file is
4556 lib/silcutil/silclog.c.
4558 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4560 * Fixed various printing bugs on the user interface in the
4561 Irssi SILC Client. Minor changes that were forgotten from
4564 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4566 * Fixed the configure.in.pre and the compilation and distribution
4567 environment to support the new autoconf 2.52. That version is
4568 now required to compile the CVS trunk.
4570 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4572 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4573 to generally parse user@fqdn format strings. Affected file
4574 lib/silcutil/silcutil.c.
4576 * Added nickname_format and nickname_force_format fields to the
4577 SilcClientParams structure. The first one defines the format
4578 for the nicknames that the library will enforce if the receives
4579 multiple same nicknames. The second one is boolean value and
4580 can be used to force the library to always enforce the format
4581 to the nicknames regardles whether there are multiple nicknames
4582 or not. This configurable formatting was employed to flexibly
4583 support accessing multiple nicknames from the user interface.
4584 The userinterface can now set the nicknames to what ever format
4585 they prefer. Affected file lib/silcclient/silcapi.h.
4587 Added function silc_client_nickname_format to the file
4588 lib/silcclient/idlist.c. It performs the nickname formatting.
4590 Added new field `hostname´ to the SilcClientEntry context.
4591 It holds the hostname of the client. Affected file is
4592 lib/silcclient/idlist.h.
4594 * Irssi SILC Client sets the nicknames in nick@hostn format.
4595 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4596 irssi/src/silc/core/silc-core.c.
4598 The WHOIS printing now also shows both the real nickname and
4599 the formatted nickname so that user knows how to access the
4600 user if there are multiple same nicknames cached. Affected
4601 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4602 printing formatting too to take the hostname now as a separate
4603 argument. The Affected file is
4604 irssi/src/fe-common/silc/modules-formats.[ch].
4606 * Changed the silc_client_get_clients_local to accept the formatted
4607 nickname as argument. It accepts the real nickname too but the
4608 formatted nickname can be used to find the true entry from
4609 multiple entries. Affected file lib/silcclient/silcapi.h and
4610 lib/silcclient/idlist.c.
4612 * Added nickname_format_parse field to the SilcClientParams.
4613 It is a callback function provided by the application to parse
4614 the nickname out of the formatted nickname string. The library
4615 calls it to get the nickname from the formatted string. Since
4616 the application generally knows better the format of the nickname
4617 string it parses it instead of the library, even though library
4618 encodes the formatted string. If the callback function is not
4619 provided then the library will use the string as is. The
4620 affected file is lib/silcclient/silcapi.h.
4622 * All the nickname strings passed to the client library in
4623 commands are now expected to be formatted nickname strings.
4624 If the command does not support the formatted nickname string
4625 it will assume that the sent string is the actual nickname.
4626 Affected file lib/silcclient/command.c.
4628 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4630 * Added public key authentication support to OPER and SILCOPER
4631 commands in the client library. Affected file is
4632 lib/silcclient/command.c.
4634 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4636 * Changed the get_auth_methdod client operation to be asynchronous.
4637 It can be async if the application resolves the authentication
4638 method from the server during the negotiation. Added new
4639 SilcGetAuthMeth completion callback that the application will
4640 call after resolving the authentication method.
4642 Added function silc_client_request_authentication_method that
4643 the application can use to resolve the authentication method
4644 from the server. Added also SilcConnectionAuthRequest callback
4645 that the library will call after the server has replied. The
4646 application can call this function if it does not know the
4647 current authentication method.
4649 Affected files are lib/silcclient/client.c and
4650 lib/silcclient/silcapi.h.
4652 * The Irssi SILC client now automatically resolves the authentication
4653 method incase any configuration information is not present (and
4654 currently there never is). The affected file is
4655 irssi/src/silc/core/client_ops.c.
4657 * Fixed public key authentication from the client library.
4658 Affected file lib/silcclient/protocol.c. Changed also the
4659 protocol specification about the public key authentication in
4660 the connection authentication protocol. The actual data to be
4661 signed is now computed with a hash function before signing.
4663 * Fixed the public key authentication from the server as well.
4664 Affected file silcd/protocol.c.
4666 * Removed the mlock()'s from the memory allocation routines.
4667 Affected file lib/silcutil/silcmemory.c. The ./configure does
4668 not check anymore for the mlock(). Affected file is
4671 * Fixed USERS command in server to allow the execution of the
4672 command for private and secret channels if the client sending
4673 the command is on the channel. Affected file silcd/command.c.
4675 * Fixed silc_client_get_clients_local to return the clients
4676 count correctly. It could return wrong value. Affected file
4677 lib/silcclient/idlist.c.
4679 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4681 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4682 types. The assembler optimizations seemed not to like 64-bit
4683 data types. The assmebler optimizations thus are now enabled
4684 also for BSD systems as opposed to only enable them for Linux.
4686 * Do not check for threads at all on BSD systems. Affected
4687 file configure.in.pre.
4689 * Removed -n and -h options from the Irssi SILC Client since
4690 they are not used in silc.
4692 * Fixed the prime generation to assure that the first digit
4693 of the generated random number is not zero since our conversion
4694 routines does not like number strings that starts with zero
4695 digit. If zero digit is seen the random number is regenerated.
4696 This caused some corrupted RSA keys when the zero first digit
4697 was met. Affected file lib/silcmath/silcprimegen.c.
4699 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4701 * Fixed WIN32 configuration in the ./configure script.
4702 Fixed to include xti.h on environments that has it.
4703 Patches by Carsten Ilchmann and andrew.
4705 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4707 * Changed the silc_id_create_client_id to be collision
4708 resistant. It is now assured that there cannot be created
4709 two same client ID's. I suspect that some weird bugs in
4710 the server were actually caused by duplicate Client IDs.
4711 Affected file silcd/serverid.[ch]. A router receiving
4712 new ID now also assures and informs the sending server
4713 if the ID caused collision.
4715 * Changed the silc_id_create_channel_id to also assure that
4716 there are no collisions.
4718 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4720 * Statement about ignoring the Mutual Authentication flag when
4721 performing rekey with PFS was a bit misleading. It is ignored
4722 if it was set in the initial negotiation, it cannot be even
4723 set in the rekey. Fixed in the ke-auth draft. Started the
4724 new versions of the protocol drafts in the doc/.
4726 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4728 * Fixed a bug in silc_client_command_identify_save when saving
4729 new channel information. The channel name was no duplicated
4730 and caused crash on exit. Affected file is
4731 lib/silcclient/command_reply.c.
4733 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4735 * Fixed the getkey command handling in the server. Send just
4736 empty OK reply to the sender if the key could not be fetched
4737 (but everything else was ok, like the key just was not available).
4738 Changed the public key parameter to optional in the protocol
4739 specs so that empty OK reply can be sent. Affected file
4742 Added a message to Irssi SILC client to tell to user if the
4743 server did not return a public key.
4745 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4747 * Fixed a channel key regeneration bug. It registered new
4748 timeout tasks exponentially until all system resources were
4749 used. Affected file silcd/server.c.
4751 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4753 * Added the SILC Document generator to the scripts/silcdoc.
4754 It can be used to generate the Toolkit Reference Manual out
4755 of the source tree. Internally it will also use the RoboDoc
4756 generator now imported in util/robodoc.
4758 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4760 * Added couple of return's in rekey protocol if error orccurred
4761 during the protocol. The execution must be terminated.
4762 Affected file silcd/protocol.c. Also, terminate the protocol
4763 always with timeout.
4765 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4767 * The client's Client ID was created initally from the wrong
4768 nickname (it could have been in format nick@host) in the
4769 silc_server_new_client. Affected file silcd/packet_receive.c
4771 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4773 * Added some SILC_LOG_ERROR's to various error conditions
4774 if client could not be added to ID cache. Affected files
4775 silcd/packet_receive.c and silcd/server.c.
4777 * When client's sock->user_data is freed, NULL also the
4778 client->router and client->connection pointers. Added check
4779 for these pointers being NULL to various places around the
4780 code. Affected file silcd/server.c.
4782 * Added client->data.registered == TRUE checks to various
4783 places around the code to assure that unregistered client's
4784 are not handled when it is not allowed. Affected file
4787 * Added `bool registered' fields to all
4788 silc_idlist_[server|client]_get_* routines to indicate whether
4789 the fetched client needs to be registered or not. Affected
4790 file silcd/idlist.[ch].
4792 * Add your own entry as registered to the ID cache in the
4793 server. Affected file server.c.
4795 * Fixed a bug in silc_server_new_server. The SilcServer was
4796 set as the new server's context instead of SilcServerEntry.
4797 This naturally caused some weird bugs.
4799 * Added "updated" field the SilcChannelEntry which indicates
4800 the time since the channel entry was last accessed. This
4801 can be used to determine whether it is necessary to
4802 announce the channel after backup resuming protocol.
4803 Affected files silcd/idlist.[ch].
4805 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4807 * Do not delete the channel rekey task when adding it
4808 for in silc_server_create_channel_key.
4810 * Changed the silc_server_create_channel_key to return
4811 TRUE or FALSE to indicate the success of the channel key
4814 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4816 * Fixed MSVC++ project files and added missing files to
4817 Makefiles under win32/.
4819 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4821 * Do not add TCP_NODELAY flag if the operating system
4822 does not have it defined. Affected files are
4823 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4825 * Fixed buffer overflow from Irssi SILC Client. Affected
4826 file irssi/src/fe-common/core/themes.c.
4828 * Fixed double free in client library in the file
4829 lib/silcclient/client.c when disconnecting from server.
4831 * Applied double free patch from cras to Irssi SILC client.
4832 Affected files irssi/src/core/[modules/expandos].c
4834 * Fixed the disconnection handling to Irssi SILC Client.
4835 The application must call silc_client_close_connection
4836 in ops->connect client operation in case of failure of
4837 the connection. Affected file is
4838 irssi/src/silc/core/client_ops.c.
4840 * Do not set sock->protocol to NULL in the function
4841 silc_client_close_connection after executing the protocol's
4842 final callback since the sock might not be valid anymore.
4843 Affected file lib/silcclient/client.c.
4845 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4847 * Do not enable SILC_THREADS if the linking with libpthread
4848 did not happen. Affected file configure.in.pre.
4850 * Added notion to protocol specification that server must
4851 verify the sent authentication payload with CMODE when
4852 setting the channel founder key. Implemented it to the
4853 server. Affected file silcd/command.c.
4855 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4857 * Added _EXTRA_DIST SILC distribution variable to the
4858 distributions file. It is used to conditionally add extra
4859 files or directories to the specific distribution. Affected
4860 files ./prepare, Makefile.am.pre and distributions.
4862 Removed the `_' from the start of the distribution names.
4865 * Added README.WIN32 for instructions to compile the Toolkit
4868 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4870 * Fixed a double free in disconnection in the server. Affected
4871 file is silcd/server.c.
4873 * Fixed the lib/silcske/groups.c to work now also with GMP
4874 MP library. The string conversion did not work when using
4875 specific base and the base is indicated in the string as well.
4877 * Created win32/ directory which now includes MSVC++ specific
4878 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4879 It will appear only in the toolkit distribution
4881 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4883 * Changed the key material distribution function in case when
4884 the hash output is too short. The data is now concatenated
4885 a bit differently than it used to. Made the change to the
4886 SKE protocol specification.
4888 * Added better GMP detection to configure.in.pre. A patch
4891 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4893 * Fixed a minor bug in SKE that might cause some problem on
4894 some platforms. Affected file lib/silcske/silcske.c.
4896 * Added the cookie checking for initiator in the SKE. It checks
4897 that the responder returns the sent cookie unmodified. The
4898 affected file is lib/silcske/silcske.c. Added new SKE
4899 error type INVALID_COOKIE that can be sent during the
4900 negotiation. Fixed some memory leaks as well.
4902 * Added the "invalid cookie" error message to Irssi SILC client's
4905 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4907 * Added `task_max' field to the SilcClientParams to indicate
4908 the maximum tasks the scheduler can handle. If set to zero,
4909 default values are used. Affected file lib/silcclient/silcapi.h.
4911 * Fixed memory leaks in silc_client_close_connection. Affected
4912 file lib/silcclient/client.c.
4914 * Added silc_client_del_client_entry to client library to free
4915 all memory of given client entry. Affected file is
4916 lib/silcclient/idlist.[ch].
4918 * Added new functions silc_client_del_channel and
4919 silc_client_del_server to delete channel and server entries.
4920 Affected file lib/silcclient/[silcapi.h/idlist.c].
4922 * Removed silc_client_del_client_by_id from silcapi.h.
4924 * Fixed the INFO command to return the server's own info
4925 correctly when querying by Server ID. Affected file is
4928 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4930 * Removed the non-blocking settings in WIN32 code in the
4931 silc_sock_[read/write] and added SleepEx instead. Affected
4932 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4933 of input data is now checked with FIONREAD and ioctlsocket.
4935 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4937 * Call silc_schedule_task_del_by_context in the
4938 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4939 Affected file lib/silccore/silcprotocol.c.
4941 * Call silc_protocol_cancel for active protocols in the
4942 silc_server_close_connection if the funtion
4943 silc_server_free_sock_user_data has not been called.
4944 Affected file silcd/server.c.
4946 * Generic tasks cannot be deleted using the del_by_fd
4947 task deleting function since generic tasks does not match
4948 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4950 * Added a notion to SILCOPER help file that the SILCOPER works
4951 only on router server, not on normal server.
4953 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4955 * Added for WIN32 support for the new scheduler as well.
4956 Affected file lib/silcutil/win32/silcwin32schedule.c.
4958 * Fixed the SHA1 implementation to work on various platforms.
4960 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4962 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4963 API. It is part of the scheduler now. Everything else is
4964 as previously but some functions has changed their names.
4965 Checkout the lib/silcutil/silcschedule.h for the interface.
4966 Updated all applications to use the new interface. Affected
4967 files are lib/silcutil/silcschedule.[ch].
4969 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4971 * Found a bug in the SKE implementation. The HASH value,
4972 specified by the protocol, was not computed correctly. The
4973 public key of the responder was not added to the computation
4974 even though it is mandatory. Affected file lib/silcske/silcske.c.
4975 This unfortunately causes incompatibilities with older
4976 clients and servers.
4978 * Added WIN32 specific network init and uninit functions:
4979 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4980 the Winsock2. Affected file lib/silcutil/silcnet.h and
4981 lib/silcutil/win32/silcwin32net.c.
4983 * Set the socket always to nonblocking mode on WIN32 after
4984 reading data or writing data. Affected file is
4985 lib/silcutil/win32/silcwin32sockconn.c.
4987 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4989 * Fixed various compilation problems under WIN32. Affected
4990 files lib/silcutil/win32/silcwin32thread.c and
4991 lib/silcutil/win32/silcwin32schedule.c.
4993 * Removed all _internal.h #includes from public header
4994 files. Internal headers must never be included from
4997 Removed also the lib/silcske/payload_internal.h file.
4999 * All include files that may be needed (public and some others
5000 included by the public headers) by application developers are
5001 now copied to the ./includes directory. It does not copy any
5002 internal headers. Affected file Makefile.defines.pre and all
5003 Makefile.am's under lib/ and subdirs.
5005 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5007 * Do not change the ~/.silc directory's permissions automatically.
5008 Affected file irssi/src/silc/core/clientutil.c.
5010 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5012 * Do not cancel the protocol in silc_server_close_connection
5013 it might cause recursion. Now cancelled in the function
5014 silc_server_free_sock_user_data. Affected file silcd/server.c.
5016 * Fixed the silc_server_remove_clients_by_server to regenerate
5017 the channel keys correctly finally. Added also new function
5018 silc_server_remove_clients_channels to actually do it.
5019 Affected file silcd/server.c.
5021 * Fixed the silc_server_new_channel to not crash by giving
5022 wrong router to the new channel. Affected file is
5023 silcd/packet_receive.c.
5025 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5027 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
5028 which is given as argument to the silc_client_alloc now.
5029 It can be used to configure the client and set various parameters
5030 that affect the function of the client.
5032 * The USERS command in server did not check whether the channel
5033 is private or secret. Affected file silcd/command.c.
5035 * Added new argument to the USERS command in protocol specification.
5036 The USERS command now can take the channel name as argument
5037 as well. Added support for this in client and server and
5038 updated the protocol specs.
5040 * Completed the GETKEY command in client. It can be now used
5041 to fetch also servers public key not only some clients.
5042 Affected files lib/silcclient/command[_reply].c.
5044 * Added silc_client_get_server to return server entry by the
5045 server name. Affected files lib/silcclient/silcapi.h and
5048 * Redefined the IDENTIFY command in protocol specification to be
5049 more generic. It now can be used to query information about
5050 any entity in the SILC Network, including clients, servers and
5051 channels. The query may be based either the entity's name
5052 or the ID. Added support for this in both client and server.
5054 Affected files silcd/command.c and lib/silcclient/command.c
5055 and command_reply.c.
5057 * Optimized the WHOIS and WHOWAS commands in the server. Removed
5058 the _from_client and _from_server functions. Affected file
5061 * Added silc_client_get_channel_by_id_resolve to the file
5062 lib/silcclient/silcapi.h to resolve channel information by
5063 its ID. Added also silc_client_get_channel_by_id that
5064 does not resolve it from the server.
5066 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5068 * Added SilcServerEntry context into the client library
5069 to represent one server. The INFO command now allocates
5070 these to save the resolved server info. For now on the
5071 client library will also keep information about servers,
5072 connected and resolved with INFO.
5074 The INFO command now allocates the SilcServerEntry context
5075 and saves the server info there. The COMMAND_REPLY in
5076 the INFO now returns the parameters to application in
5077 same order as defined in the protocol specification.
5079 The entries are cached in the client->server_cache.
5081 * The INFO command is now issued after received the Client ID
5082 from the server. Affected file lib/silcclient/client.c.
5084 * The CMODE_CHANGE notify may now return also an SilcServerEntry
5085 to the application as the mode changer might be server.
5086 It is guaranteed that NULL is not returned anymore to the
5087 application. Affected file lib/silcclient/client_notify.c.
5089 The ID Type is now also passed to the application so that
5090 it can check whether the returned entry is SilcClientEntry
5093 Added new function silc_client_get_server_by_id to return
5094 the server entry by ID. Affected files are the
5095 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
5097 * Do not create the channel in the Irssi SILC Client when issuing
5098 the JOIN command but when received the sucessful JOIN command
5099 reply. Otherwise the channel might get created even though we
5100 could not join it. The Affected file is
5101 irssi/src/silc/core/[silc-channels.c/client_ops.c].
5103 * Fixed a channel joining bug in router. The router must also
5104 check the channel modes, invite and ban lists etc. when serving
5105 the JOIN command sent by normal server. Affected file is
5106 silcd/command.c. The router now resolves the client's
5107 information from the server who sent the JOIN command if it
5108 does not know it, and processes the JOIN command only after
5111 * Changed the SilcCommandCb to take new argument; void *context2.
5112 Affected file lib/silccore/silccommand.h
5114 The second argument in the command callbacks in the server now
5115 includes the SilcServerCommandReplyContext if the command was
5116 called as pending command callback from the command reply.
5117 Otherwise it is NULL. When called as pending the status of the
5118 command reply will be checked and if it was erronous the
5119 error will be sent to the original sender of the command.
5120 This way the client always receives the error messages even
5121 though the server was actually the one who received the error
5122 when it resent the command to router, for example. Affected
5123 files silcd/command[_reply].[ch].
5125 * Fixed sending WHOWAS command's error message to client if
5126 the requested client could not be found. It was missing.
5129 * Changed the CMODE and CUMODE commands reply arguments in the
5130 protocol specification. The Channel ID is now sent in both
5131 of the commands to identify the channel. Implemented this
5132 new feature to the client and server. Affected files
5133 lib/silcclient/command_reply.c and silcd/command.c.
5135 * Made better checks for invite and ban lists in the JOIN
5136 command in server. Affected file silcd/command.c.
5138 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5140 * The server now performs the incoming host IP/DNS lookup
5141 using the silc_socket_host_lookup and thus does not block
5142 the server anymore. Affected file silcd/server.c.
5144 * Completed the multi-thread support for SILC Scheduler in
5145 the lib/silcutil/silcschedule.c.
5147 * Fixed the configure.in.pre to detect the pthread correctly
5150 * Fixed a deadlock in silc_task_queue_wakeup in the file
5151 lib/silcutil/silctask.c.
5153 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5155 * Added new function silc_schedule_wakeup that is used in
5156 multi-threaded environment to wakeup the main thread's
5157 schduler. It needs to be used when a thread adds a new task
5158 or removes a task from task queues. After waking up, the
5159 scheduler will detect the task queue changes. If threads
5160 support is not compiled in this function has no effect.
5161 Implemented the wakeup mechanism to both Unix and WIN32
5162 systems. Affected files are lib/silcutil/silcschedule.[ch],
5163 lib/silcutil/unix/silcunixschedule.c and the
5164 lib/silcutil/win32/silcwin32schedule.c.
5166 * Added new function silc_task_queue_wakeup to wakeup the
5167 scheduler by the specified task queue. Affected file
5168 lib/silcutil/silctask.[ch].
5170 * The silc_socket_host_lookup_start now wakes up the scheduler
5171 after adding the timeout task. Affected file is
5172 lib/silcutil/silcsockconn.c.
5174 * The silc_socket_host_lookup is synchronous now if the threads
5175 support is not compiled in. However, the callback is still
5176 called asyncronously through the scheduler, anyway. Affected
5177 file lib/silcutil/silcsockconn.c.
5179 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5181 * Added new function silc_socket_host_lookup to perform
5182 asynchronous IP and FQDN lookups for the socket connection.
5183 Affected files lib/silcutil/silcsockconn.[ch].
5185 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5187 * Added SILC_MUTEX_DEFINE to define the mutex on environments
5188 that may or may not compile the mutex support in.
5190 Changed the silc_mutex_alloc interface. It allocates the
5191 mutex now to the sent pointer and returns TRUE or FALSE.
5193 Affected file lib/silcutil/silcmutex.h.
5195 * Wrote the SILC Task Queue interface to support multi-threads.
5196 Affected file lib/silcutil/silctask.[ch].
5198 * Wrote the SILC Scheduler to support multi-threads. Affected
5199 file lib/silcutil/silcschedule.c.
5201 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5203 * Implemented the SILC Mutex API and SILC Thread API for WIN32
5204 in lib/silcutil/win32/.
5206 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5208 * Defined SILC Mutex API and SILC Thread API and implemented
5209 them for Unix. Affected files are
5210 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
5211 lib/silcutil/unix/silcunixmutex.c and
5212 lib/silcutil/unix/silcunixthread.c.
5214 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5216 * Fixed the silc_server_remove_clients_by_server's channel
5217 key re-generation. The hash table handling was incorrect
5218 and would not work with many channels. Affected file is
5221 * Fixed some memory leaks around the server code.
5223 * Rewrote the silc_server_get_users_on_channel to support IPv6
5224 based Client ID's. Affected file silcd/server.c.
5226 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
5227 specification. However, a separate document must be written
5228 to define the detailed signing procedure and the payload
5229 associated with the flag. Defined the flag to the
5230 lib/silccore/silcchannel.h as well.
5232 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5234 * Changed the dynamic tables to static size tables in the
5235 lib/silccrypt/silchmac.c.
5237 * Removed GCC dependencies from the code. A patch by cras.
5239 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5241 * Do not show the error "Error receiving packet bla bla"
5242 in server if it really was not an error (-2 means that reading
5243 is pending). Affected file silcd/server.c.
5245 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5247 * Fixed a possible crash in silc_server_remove_clients_by_server
5248 in silcd/server.c. Fixed there also some memory leaks.
5250 * Fixed the silc_idlist_replace_client_id. It could replace
5251 wrong key in the hash table. Affected file silcd/idlist.c.
5253 * Do not check whether there are global users on the channel
5254 if the channel->global_users is FALSE. Affected functions
5255 silc_server_remove_from_one_channel and
5256 silc_server_remove_from_channels in silcd/server.c. Also,
5257 do not check if the removed client is local as we can be
5258 sure that global client was not removed from the channel
5259 and checking for global users is not needed.
5261 * The silc_server_remove_clients_by_server now re-generates
5262 the channel keys correctly for those channels that had
5263 clients removed from them. Affected file silcd/server.c.
5265 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5267 * Found the reason of random crashes in the server. We weren't
5268 ignoring the SIGPIPE signal (which can be sent in write())
5269 and it crashed the server. Affected file silcd/silcd.c.
5271 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5273 * Assure that sock->user_data is not NULL in the function
5274 silc_server_packet_send in silcd/packet_send.c.
5276 * Disconnect the remote connection if it could not be added
5277 to any ID lists in the server. The affected file is
5280 * Check in silc_server_packet_send[_real/dest] that the
5281 socket is not disconnecting and ignore the data if it is.
5282 Affected file silcd/packet_send.c.
5284 * Define inline to __inline on native WIN32 compilation.
5285 Affected file includes/silcwin32.h.
5287 * Added some explicit type casts for inline code since MSVC
5288 require them. Affected files lib/silcutil/silcbuffer.h,
5289 lib/trq/silcdlist.h and lib/trq/silclist.h.
5291 * Print warning in log files from now on if the packet
5292 decryption fails. Affected file silcd/server.c.
5294 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5296 * Changed the `say' client operation's interface to accept
5297 new `type' argument to indicate the type of the message sent
5298 by the library. The application may filter the library's
5299 messages according the type. The affected file is the
5300 lib/silcclient/silcapi.h.
5302 * Added two new functions to lib/silcclient/silcapi.h:
5303 silc_client_del_client and silc_client_del_client_by_id.
5304 Affected file lib/silcclient/idlist.c.
5306 * Moved the clientincludes.h from includes/ to silc/ and
5307 serverincludes.h from includes/ to silcd/.
5309 * The modes for the CMODE and CUMODE are now passed as
5310 uint32 for application with COMMAND_REPLY. The affected
5311 file is lib/silcclient/command_reply.c.
5313 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5315 * /WHOIS without arguments shows client's own information.
5316 Affected file lib/silcclient/command.c.
5318 * Changed PING to not accept any arguments. The specs
5319 says that client can ping only the connected server so
5320 requiring an argument is not needed. Affected file is
5321 lib/silcclient/command.c.
5323 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5325 * Fixed a fatal bug in private message sending and reception
5326 encryption and decryption when using private message keys.
5327 The implementation was incorrect and did not follow the
5328 specification. It causd that some of the message were
5329 lost since it did not use the sending and receiving keys
5330 as the protocol suggests. This has been fixed and will cause
5331 incompatibilities with older clients when sending private
5332 message encrypted with private message keys. Affected files
5333 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
5334 and various other in Irssi SILC Client.
5336 Added `responder' boolean argument to the functions
5337 silc_client_add_private_message_key[_ske] to indicate when
5338 the key is added as responder or initiator of the key
5341 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5343 * Removed the silc_ske_check_version function and created
5344 a SilcSKECheckVersion callback. Added also a function
5345 silc_ske_set_callbacks that is now used to set all SKE
5346 callbacks. The callback functions are not given to
5347 the SKE functions anymore, but this function is used to
5350 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
5352 * Added `silc_version' argument to the silc_client_alloc
5353 to define the version of the application for the library.
5354 The library will use the version string to compare it
5355 against the remote host's (usually a server) version
5356 string. Affected file lib/silcclient/silcapi.h
5358 * Added the KE protocol context to Key Agreement context
5359 in client library so that we can abort the SKE if it
5360 is in process when we get timeout. Affected file is
5361 lib/silcclient/client_keyagr.c.
5363 * Do not resolve the client ID forever if it returns in the
5364 first time that such client does not exist. This was done
5365 for example with private message. Affected file is
5366 lib/silcclient/client_prvmsg.c.
5368 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5370 * Do not add regex.h for WIN32. The affected file
5371 includes/silcincludes.h.
5373 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
5374 not work yet 100%. It generates the DLL's automatically
5375 when compiling with --with-win32 under cygwin.
5377 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5379 * lib/contrib/regex.c is not compiled on WIN32.
5381 * Added silc_net_get_socket_opt function to the
5382 lib/silcutil/silcnet.h.
5384 * Added includes/silcwin32.h for WIN32 specific includes
5387 * Do not use ptime structure or any of the posix process
5388 functions on WIN32 in lib/silccrypt/silrng.c.
5390 * Added silc_gettimeofday to provide generic function
5391 for struct timeval on all platforms. Added the function
5392 to lib/silcutil/silcutil.h.
5394 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5396 * Moved the lib/silccore/silcsockconn.[ch] to the utility
5397 library as they clearly belong there. As a plus side we
5398 can make the actual socket connection routines platform
5401 Added also new generic function silc_socket_read and
5402 silc_socket_write (that used to be silc_packet_[read/write].
5403 The implementation of these are platform specific.
5405 * Added WIN32 specific routines of silc_socket_[read/write]
5406 to lib/silcutil/win32/silcwin32sockconn.c.
5408 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5410 * Added preliminary support for native WIN32 compilation under
5411 cygwin (using the -mno-cygwin option for GCC) to the
5412 ./configure.in.pre. The --with-win32 now prepares the
5413 compilation for native WIN32.
5415 * Rewrote the SILC Scheduler interface in the file
5416 lib/silcutil/silcschedule.h. The scheduler is now context
5417 based and does not have anymore any global static scheduler.
5418 Moved the Unix scheduler to the lib/silcutil/unix/ directory
5419 and created lib/silcutil/win32 directory for WIN32 based
5422 * Added Unix specific network routines to the
5423 lib/silcutil/unix/silcunixnet.c and the old
5424 lib/silcutil/silcnet.c includes now only generic routines.
5426 Added WIN32 specific network routines to the
5427 lib/silcutil/win32/silcwin32net.c.
5429 * Added Unix specific utility functions from the
5430 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
5432 * Added WIN32 SILC Scheduler to the file
5433 lib/silcutil/win32/silcwin32schedule.c. The code is of course
5436 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5438 * Do not handle JOIN notify in the server if the target client
5439 is not registered (idata->registered == FALSE). The affected
5440 file is silcd/packet_receive.c.
5442 * Update the nickrec->founder in event_cumode in the Irssi SILC
5443 client. Affected file irssi/src/silc/core/silc-channels.c.
5445 * Fixed the CUMODE_CHANGE notify handling in the server when
5446 server and router are announcing their clients on channels.
5447 Now the mode changes are saved and notified correctly. The
5448 affected file is /silcd/packet_receive.c.
5450 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
5451 They really did not replace the cache entry in the ID Cache.
5452 Now they do that. Affected file silcd/idlist.c.
5454 * Fixed the KICK notify handling in the Irssi SILC client to
5455 update the channel records so that the kicked client does not
5456 appear to be on the channel. The affected file is
5457 irssi/src/silc/core/silc-channels.c.
5459 * Always update the conn->current_channel when executing command
5460 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
5462 * Fixed the KILL notify handling in Irssi SILC client to remove
5463 the killed client on all channels.
5465 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5467 * Fixed the silc_parse_command_line to remove extra spaces
5468 from the start and end of the arguments. Affected file is
5469 lib/silcutil/silcutil.c.
5471 * Cancel and free any active protocol in the function
5472 silc_server_close_connection. Affected file silcd/server.c.
5474 * Cancel and free any active protocol in the function
5475 silc_client_close_connction. Affected file is
5476 lib/silcclient/client.c.
5478 * Do not execute the KILL command for clients that are in
5479 history (ie. they are not in the network). Affected file is
5482 * Fixed KILL notify handling, client does not crash anymore.
5483 Affected file irssi/src/silc/core/silc-channels.c.
5485 * Reduced the default packet buffer size from 2048 to 1024 in
5486 lib/silccore/silcpacket.c.
5488 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5489 counter to the SKE context that is incresed when the SKE library
5490 performs async operation outside the library. If the outside
5491 process frees the SKE context and FREED status will be set
5492 and the library will detect after the sync operation that the
5493 libary is freed. The affected files are
5494 lib/silcske/silcske[_status].[ch].
5496 * Resolve the client entry information in the function
5497 silc_client_channel_message to assure that NULL pointer is not
5498 passed as client entry to the application. */
5500 * Fixed the task timeout calculation to assure that there is
5501 never negative timeouts. The affected file is
5502 lib/silcutil/silcschedule.c.
5504 * Fixed the channel user mode notification sending in server.
5505 It was sent point-to-point to the router (or to server by router)
5506 but it needs to be destined to a channel. The routines now
5507 supports sending the channel user mode notifys to the channels
5508 when announcing clients and channels. Affected files are
5509 silcd/server.c and silcd/packet_receive.c.
5511 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5512 It did not actually replace the old channel entry in the cache.
5513 Affected file lib/silcclient/client_notify.c.
5515 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5517 * Fixed a possible crash in silc_packet_send_prepare. It now
5518 assures always that there is enough space in the buffer and
5519 at the tail area of the buffer (for MAC).
5521 Fixed the inbound buffer reallocation in silc_packet_read.
5522 It was old code and did not handle the reallocation correctly.
5525 The affected file is lib/silccore/silcpacket.c.
5527 * Fixed buffer overflow in silc_parse_nickname in the file
5528 lib/silcutil/silcutil.c.
5530 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5532 * make install generates new server keys only if there is not
5535 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5537 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5538 Added check that if the NOREPLY is set then we will not send
5539 the away message. This avoids infinite loop of away messages
5540 if both clients are away. The affected file is
5541 lib/silcclient/client_prvmsg.c.
5543 * Fixed client crash if /NICK was given without arguments.
5544 Affected file lib/silcclient/command.c.
5546 * Server does not send the invite list in INVITE command back
5547 to the client if the list was not altered. Added this notion
5548 to the protocol spec as well. Affected file silcd/command.c.
5550 Fixed possible crash in INVITE command by checking the
5551 value of silc_server_get_client_route command.
5553 * Fixed the INVITE notify type handling. The arguments are now
5554 taken in correct order and client does not crash. The affected
5555 file is irssi/src/silc/core/silc-channels.c.
5557 Removed the "Inviting xxx to channel" message from the
5558 client library away and let the application handle it.
5559 Affected file lib/silcclient/command.c. Added that message
5560 to Irssi SILC client's message formats.
5562 * Fixed CMODE command crash in client. It now checks the
5563 amount of arguments correctly and does not crash. The affected
5564 file is lib/silcclient/command.c.
5566 * Do not create new channel automatically in silc_channels_join
5567 but check whether the channel by that name already exists.
5568 Affected file irssi/silc/core/silc-channels.c.
5570 * Do not send the SERVER_SIGNOFF to router if the disconnected
5571 entity was the router. Affected file silcd/server.c.
5573 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5574 SILC client as it was missing from there.
5576 Added the handling of the KICK notify to the Irssi SILC client
5577 as it was missing. Added "you have been kicked" message to
5578 Irssi SILC client's message modules formats.
5580 Added the handing of the KILL notify to the Irssi SILC client
5581 as it was missing. Added the kill message module formats
5584 The affected file is irssi/src/silc/core/silc-channels.c.
5586 * The router did not save the channel mode the server announced.
5587 Affected file silcd/packet_receive.c.
5589 * Fixed a possible crash in INFO command in server. If the
5590 server did not provide the server info it crashed. Affected
5591 file silcd/command.c.
5593 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5595 * Fixed the GETKEY command in the server to check also the
5596 global list. Otherwise the GETKEY would not work correctly
5597 in normal SILC server. Affected file silcd/command.c.
5599 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5601 * Fixed GETKEY crash, it crashed if the command did not succseed.
5603 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5605 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5606 is now real and not just an macro interface to GMP.
5608 Removed the entire GMP from the source tree and imported new
5609 NSS MPI library instead. Reason for removing GMP is that it is
5610 extremely large and compiles extremely slow. The NSS MPI
5611 is only a few files and compiles in less than 10 seconds.
5612 The speed is also about the same as GMP. The MPI is imported
5613 to lib/silcmath/mpi.
5615 If the system has GMP installed we will still use the GMP.
5616 If it is not then the NSS MPI will be compiled.
5618 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5620 * Merged a long nickname (127 characters long) crash bugfix from
5621 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5623 * Merged a freed memory reference bugfix from Irssi CVS tree.
5624 Affected file irssi/src/core/commands.c.
5626 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5628 * Added the server's public key sving and verification to the
5629 server when performing the SKE. This was missing and the
5630 remote server's (or router's) public key was accepted without
5631 checking whether we have it previously or trust it at all.
5632 Affected file silcd/protocol.c.
5634 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5636 * Check in the silc_server_timeout_remote if protocol is active
5637 and make sure that the protocol's final callback is called so
5638 that all memory if freed. Affected file silcd/server.c.
5640 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5642 * silc_server_whois_send_reply crashed the server if the nickname
5643 was 127 characters long. Affected file silcd/command.c.
5645 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5647 * Added sanity check to the silc_server_new_client. If the hostname
5648 is provided inside username then check that the provided hostname
5649 really is the same as the resolved one. If the hostname was not
5650 resolved then check it from the public key. Affected file is
5651 silcd/packet_receive.c.
5653 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5654 if the server disconnected us and the connection is not valid
5655 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5657 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5658 the library to the lib/silcutil/silcutil.[ch].
5660 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5662 * Close log file after open. Affected file
5663 lib/silcutil/silclog.c.
5665 * Check whether sock == NULL in silc_client_send_packet and return
5666 if it is. Affected file lib/silcclient/silcclient.c.
5668 * Check rec->entry == NULL in the Irssi SILC Client before
5669 sending the channel message. Affecte file is
5670 irssi/src/silc/core/silc-servers.c.
5672 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5674 * Merged a splitted window bugfix from Irssi CVS tree. The
5675 affected file is irssi/src/fe-text/textbuffer-view.c.
5677 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5678 It did not print nickname.
5680 * Improved the distributions system a bit.
5682 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5684 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5685 irssi/src/fe-text/gui-window.c.
5687 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5688 to in-active server. The affected file is
5689 irssi/src/silc/core/client_ops.c.
5691 * Resolve the client in USERS command reply if the entry does
5692 not have username resolved. The affected file is
5693 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5694 command to WHOIS command to really resolve stuff. The USERS
5695 is not used any more in any critical section so WHOIS can
5696 be used even though it might be slower than IDENTIFY.
5698 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5701 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5703 * Changed the protocol API a bit more consistent in the
5704 lib/silccore/silcprotocol.[ch].
5706 * Changed the following headers to ROBODoc format:
5708 lib/silccore/silcpayload.h
5709 lib/silccore/silcprotocol.h
5710 lib/silccore/silcsockconn.h
5712 All core library headers are now formatted.
5714 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5716 * Fixed a bug in Irssi SILC client; do not show that you are
5717 server/router operator if you really are not. Affected file is
5718 irssi/src/silc/core/client_ops.c.
5720 * Renamed silc_command_free_payload to silc_command_payload_free.
5721 Affected file lib/silccore/silccommand.h
5723 * Added silcmath.h to include the prototoypes of various routines
5724 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5727 * Changed the following headers to ROBODoc format:
5729 lib/silccore/silcchannel.h
5730 lib/silccore/silccommand.h
5731 lib/silccore/silcid.h
5732 lib/silccore/silcidcache.h
5733 lib/silccore/silcmode.h
5734 lib/silccore/silcnotify.h
5735 lib/silccore/silcpacket.h
5736 lib/silcmath/silcmath.h
5738 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5740 * Added checking to the server code not to start the server if
5741 ciphers and stuff are not configured properly. Affected files
5742 silcd/serverconfig.[h] and silcd/server.c.
5744 * Changed the layout of the header files of the public interfaces
5745 in the SILC libraries. The new layout supports ROBODoc
5746 documentation tool (and some others) so that it is easy to create
5747 a library reference manual. All the other headers and source
5748 code must still follow the CodingStyle document. Also source
5749 code must not include these ROBODoc stuffs, only the headers.
5750 Furthermore, all public interface headers must now be named
5751 by using `silc' prefix, example: silcapi.h, silccipher.h.
5752 Some files were renamed due to this. All the other headers
5753 must not be used as public interfaces. I will update the
5754 CodingStyle document later. Changed following headers, so far:
5756 lib/silcclient/silcapi.h
5757 lib/silccore/silcauth.h
5758 lib/silccore/silcprivate.h
5759 lib/silccrypt/silcdh.h
5761 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5765 * Removed silc_client_packet_send_flush from the client library
5766 as it is not needed. Affected file lib/silcclient/client.[ch].
5768 * Added printing of message of unresolved authentication method
5769 to the Irssi SILC client. Added it to the module formats.
5770 Removed the same message from the client library.
5772 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5774 * Added new distribution feature, DISTLABEL. Every distribution
5775 can define own preprocessor label that can be used in the
5776 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5777 file distributions, acconfig.h.pre and prepare.
5779 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5781 * Added Makefile.defines_int to include the actual definitions
5782 for Makefile.defines.in. Tested the new distribution system,
5783 created distributions and tested installation.
5785 * Added AWAY message printing to the Irssi SILC client. Added
5786 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5788 * Added SCONNECT command to call the SILC's CONNECT command.
5789 Cannot use CONNECT directly since Irssi uses that internally.
5790 Affected file irssi/src/silc/core/silc-servers.c.
5792 Added ACTION local command. It is same as ME command but takes
5793 the channel as mandatory argument.
5795 Rewrote some of the Irssi's help files to suite for SILC
5798 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5800 * Added Makefile.defines[.in] that should for now on be included
5801 in all Makefile.am file in the source tree. That file includes
5802 all common compilation definitions for SILC source tree.
5804 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5806 * Minor changes to the ./prepare script to change the package
5807 name according the distribution name to the configure.in.
5809 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5811 * Created new distribution system. Added file `distributions'
5812 that defines all the distributions that can be created out of
5813 the SILC source tree. The ./prepare script now reads that
5814 file to determine how to prepare the distributions. The
5815 first argument to the ./prepare is the name of the distribution
5816 and second is the version of the distribution. If given
5817 without arguments it creates the default (toolkit) distribution
5818 with the default version (defined in ./prepare).
5820 All Makefile.am files that are subject to the distributions
5821 are now named as Makefile.am.pre. These are ./Makefile.am
5822 and lib/Makefile.am. Others may be changed later.
5824 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5826 * Added invite list, ban list, some key management and connection
5827 error message printing to module formats in the Irssi SILC client.
5829 * Added new silc_client_set_away_message to set the away message
5830 that is back to the person who sent private message. The
5831 affected file lib/silcclient/silcapi.h and the
5832 lib/silcclient/client_prvmsg.c.
5834 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5836 * Fixed the private message sending in the Irssi SILC client,
5837 added local command KEY to the Irssi SILC client.
5839 Added key management and key agreement message formats to the
5840 irssi/src/fe-common/silc/module-formats.[ch].
5842 Added USERS (alias WHO) printing, server/router operator
5843 indication and LIST command printing to the module formats.
5845 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5847 * Fixed channel joining notify handling, cumode notify handling
5848 from Irssi SILC client.
5850 * Added SILC specific module-formats to the Irssi SILC client so
5851 that SILC specific message hilighting, colors etc is possible.
5852 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5854 Added channel mode, channel user mode, actions, notices,
5855 whois and whowas printing to the the module-formats.c.
5857 * Fixed a bug in channel deletion in the server. The channel
5858 is not left to the cache even if the channel founder auth mode
5859 is set when there are no users anymore on the channel. Affected
5860 file silcd/server.c.
5862 * The silc_net_localhost now resolves the entire hostname including
5863 the domain name. Affected file lib/silcutil/silcnet.c.
5865 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5867 * Changed the ask_passphrase client operation to be ascynchronous.
5868 It has now a completion callback and a context that the
5869 application must call after it has got the passphrase from
5870 the user. Affected files lib/silcclient/silcapi.h,
5871 lib/silcclient/protocol.c, lib/silcclient/command.c and
5874 Added SilcAskPassphrase callback that the application calls
5875 to deliver the passphrase to the library.
5877 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5878 The public key verification and especially a certificate
5879 verification is asynchronous procedure.
5881 Added new SILC_SKE_STATUS_PENDING status to indicate the
5882 request is pending and a callback will be called to finalize
5885 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5886 indicate that remote end did not send its public key (or
5887 certificate), even though we require it. Added check for this
5888 condition in the SKE. This was a security bug, now fixed.
5890 Defined new SilcSKEVerifyCbCompletion callback that is called
5891 when the verification process is completed.
5893 The affected files lib/silcske/silcske_status.h and
5894 lib/silcske/silcske.[ch].
5896 * Changed the verify_public_key client operation to be async
5897 as well. Defined SilcVerifyPublicKey callback that is used to
5898 indicate the success of the public key verification process.
5900 Changed the server and client to use the new async client
5903 * Changed the Irssi SILC client's internal scheduler to be called
5904 twice as many times as it used to be. As a result the client
5905 should be a bit faster now. Affected file is
5906 irssi/src/silc/core/silc-core.c.
5908 * Added support to Irssi SILC client of asynchronous public key
5909 verification and passphrase inquiry. Affected file is
5910 irssi/src/silc/core/silc-core.c.
5912 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5914 * Do not say "You have left channel %s" in client library.
5915 Moved it to the application. Affected files are
5916 lib/silcclient/command.c and silc/client_ops.c.
5918 * Fixed silc_client_get_clients. Command context was not
5919 duplicated and was freed memory in the callback. Affected
5920 file lib/silcclient/idlist.c.
5922 * Do not say "you are now talking..." on JOIN command in the
5923 client library. The appliation must handle it.
5925 * Do not say ".. changed topic to" in command reply in the
5926 client libary. The application must handle it.
5928 * Fixed TOPIC command sending in the client library.
5930 * Fixed a memory leak in silc_client_command_free in the file
5931 lib/silcclient/command.c.
5933 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5935 * Imported a modified version of Irssi client to the source tree.
5936 The Irssi will be used to create a new client called
5937 Irssi SILC. Imported to irssi/.
5939 Added silc_core_init_finish function to the Irssi. Affected
5940 file irssi/configure.in.
5942 A lot changes in the Makefile.ams around the irssi tree.
5944 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5946 * Do not rehash if the new size is same as the old size of the
5947 hash table, in the silc_hash_table_rehash*. The affected file
5948 lib/silcutil/silchashtable.c.
5950 * Replaced hash_table_del_by_context calls from the server
5951 (when channel->user_list and client->channels) to the
5952 hash_table_del as it is sufficient and faster.
5954 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5956 * Added silc_hash_table_list, silc_hash_table_get and the
5957 SilcHashTableList structure to provide an alternative way to
5958 traverse the hash table. The affected files are
5959 lib/silcutil/silchashtable.[ch].
5961 * Changed the server's idlist routines to use the hash table
5962 routines to optimize the code.
5964 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5966 * Replaced the client entry's `channel' list and channel entry's
5967 `user_list' list to hash tables for optimized lookup. Changed
5968 the code to use the hash table interface around the code.
5969 Affected file lib/silcd/idlist.[ch].
5971 * Added `auto_rehash' boolean argument to the function
5972 silc_hash_table_alloc to indicate whether the hash table should
5973 auto-rehash when it thinks is appropriate time. It will
5974 increase the hash table size if the there is twice as much
5975 entries in the table than the size of the table, and will
5976 decrease the size if there are twice as less entries than
5977 the size of the table.
5979 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5981 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5983 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5985 * silc_idcache_purge_by_context deletes the entry now by context
5986 as it is supposed to do. Affected file lib/silccore/idcache.c.
5988 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5989 client is not anymore valid (WHOWAS givens the info) and not
5990 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5992 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5994 * Removed the `data' and `data_len' arguments from the ID Cache
5995 interfaces and added `name' argument. ID Cache does not handle
5996 anymore the binary data only a names associated with given ID.
5998 * When hashing a Client ID with silc_hash_id the entire ID is
5999 not hashed anymore, instead only the hash of the Client ID is
6000 hashed. This way we can access the Client ID from the cache
6001 with Client ID but with the hash of the ID (which is a hash of
6002 the nickname) as well without any difference in performance.
6004 Added also silc_idcache_find_by_id_one_ext to do one on one
6005 searching when we have the actual ID. Added also function
6006 silc_hash_client_id_compare. The affected files are
6007 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
6009 * When hashing the name associated with a ID it is always done
6010 in lowercase. This way we can access the cache without worrying
6011 about case-sensitivity, even though, for example nicknames are
6014 * Fixed a bug in server with channel message sending. It put
6015 wrong ID type as destination ID. The affected file
6016 silcd/packet_send.c.
6018 * silc_idcache_del_by_context now deletes from all hash tables
6019 by context. Affected file lib/silccore/idcache.c.
6021 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6023 * Changed the client library to use the new ID Cache interface.
6024 Changes around the source tree.
6026 * Added silc_hash_table_rehash_ext to rehash with specific
6027 hash function. Affected file lib/silcutil/silchashtable.[ch].
6029 * Added silc_hash_string_compare to compare two strings in the
6030 hash table. Affected file lib/silcutil/silcutil.[ch].
6032 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6034 * Added new function silc_idcache_del_by_context into the
6035 lib/silccore/idcache.[ch].
6037 * Changed the server's ID list routines to use the new ID Cache
6038 interface. Changes around the source tree.
6040 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6042 * Added silc_hash_table_del[_by_context]_ext functions in to the
6043 lib/silcutil/silchashtable.[ch].
6045 Removed silc_hash_table_find_all* routines and added new
6046 silc_hash_table_find_foreach to replace them.
6048 Added silc_hash_table_replace_ext function as extended
6049 replacing function. Separated the simple hash table interface
6050 from the extended hash table interface in the file
6051 lib/silcutil/silchashtable.h.
6053 * Fixed minor bugs and changed it to use some of the new
6054 hash table functions in lib/silccore/idcache.c
6056 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6058 * Added new function silc_hash_table_find_all to return all keys
6059 in the hash table by the specified key. As the hash table is
6060 collision resistant it also makes it possible to have several
6061 duplicate keys in the hash table. This function may be used to
6062 find all of the keys from the hash.
6064 Added user_context arguments to the SilcHashFunction,
6065 SilcHashCompare and SilcHashDestructor to deliver user specified
6068 Added new fuctions silc_hash_table_find[_all]_ext to do
6069 extended lookup with specified hash and compare functions and
6070 specified user contexts.
6072 Added new function silc_hash_table_add_ext to add the key
6073 with specified hash function and user context.
6075 Added new function silc_hash_table_foreach to traverse all
6076 entrys in the hash table. Added SilcHashForeach callback
6079 Added new function silc_hash_table_del_by_context to delete
6080 the entry only if the context associated with the key matches.
6082 Affected files are lib/silcutil/silchashtable.[ch].
6084 * Removed silc_hash_[server/client/channel]_id and added just
6085 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
6086 silc_hash_id_compare to compare two ID's using as the hash table
6087 comparison function. Added also silc_hash_data to hash
6088 binary data and silc_hash_data_compare to compare it.
6090 * Removed silc_idlist_find_client_by_hash as it is not needed
6091 anymore. Affected file silcd/idlist.[ch].
6093 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
6094 to use internally the SilcHashTable. The new ID Cache is a lot
6095 faster than the old one. Some of the ID Cache interface was also
6096 rewritten and obsolete and stupid functions were removed.
6098 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6100 * Added entry_count field to the SilcHashTable to keep the number
6101 of the entries in the table. Implemented the function
6102 silc_hash_table_rehash. Added new function
6103 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
6105 Fixed a minor bug in silc_hash_table_free.
6107 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
6108 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
6109 into the lib/silcutil/silcutil.[ch].
6111 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6113 * Implemented a collision resistant hash table into the
6114 lib/silcutil/silchashtable[ch]. See the header and the source
6115 for the SilcHashTable API.
6117 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6119 * Merged dotconf version 1.0.2 into lib/dotconf.
6121 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6123 * Do not compile anything in lib/silcsim/* if the SIM support
6124 is not enabled. The tree should now compile without problems
6127 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6129 * Compiled the SILC under cygwin. Compiled and tested briefly
6130 without problems. More tests needed. The SIMs didn't compile
6133 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
6135 * Fixed possible crash in silc_get_username in the
6136 lib/silcutil/silcutil.c.
6138 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6140 * Fixed a va_arg in silc/client_ops.c.
6142 * Oops, RC5 routines were named AES and caused some problems
6143 when not using SIM's. Affected file lib/silccrypt/rc5.c.
6145 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6147 * Added new SilcIDIP structure into the lib/silccore/id.h and
6148 replaced the old `ip' fields from all SILC ID's to that type.
6149 This is a step towards IPv6 support.
6151 The silc_id_get_len takes now the ID as an extra argument.
6152 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
6153 both IPv4 and IPv6 based ID's.
6155 The affected files are lib/silccore/id.[ch] and other files
6156 around the tree using these routines.
6158 * Removed the ID length arguments in server from various
6159 silc_server_send_notify_* routines -> they are not needed
6162 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6164 * Fixed memory leak in silc_encode_pem_file in the file
6165 lib/silcutil/silcutil.c.
6167 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6169 * Check minor version as well in the SKE. Affected files are
6170 silcd/protocol.c and lib/silcclient/protocol.c.
6172 * Added --identifier option to the server so that an identifier
6173 can be when creating the public key for the server. Affected
6174 file is silcd/silcd.c.
6176 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
6177 lib/silccrypt/silcpkcs.c.
6179 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6181 * Register default ciphers and stuff when using -C option with
6182 the server. Affected file sildc/silcd.c.
6184 * Put back the servers public key filename format, it is better
6185 than the new one. For now, the client keys are saved with the
6186 new filename format. The affected file silc/client_ops.c.
6188 * Implemented the Cipher API for the rest of the ciphers that
6189 did not implement it or implemented it the wrong way.
6191 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6193 * Register default ciphers and stuff when using the -S option
6194 in the client. Affected file silc/silc.c. Same also when
6195 creating new key pair with -C option.
6197 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * Fixed the silc_verify_public_key client operation function to
6200 save the public keys differently. The fingerprint is now
6201 used as filename and not the hostname. This way also the
6202 client keys are saved uniquely and not with hostnames. The
6203 affected file is silc/client_ops.c.
6205 * Trimmed the silc_hash_fingerprint function to remove extra
6206 whitespaces from the end of the fingerprint. The affected
6207 file is lib/silccrypt/silchash.c.
6211 * Added silc_cipher_register_default function to register all
6212 default ciphers. It can be used when configuration files
6213 does not exist and the application does not want any specific
6214 ciphers in any specific order.
6216 The SilcDList is now used as silc_cipher_list dynamically
6217 allocated cipher list. Removed the static list all together
6218 and now all ciphers must be allocated to the dynamic list.
6219 The silc_cipher_alloc routine was changed to check only the
6222 All silc_cipher_* routines that used to return int returns
6225 The affected files lib/silccrypt/silccrypt.[ch].
6227 * The same thing was done to silc_hash_* as for silc_cipher_*
6228 routines. Affected files lib/silccrypt/silchash.[ch].
6230 * The same thing was done to silc_pkcs_* as for silc_cipher_*
6231 routines. Affected files lib/silccrypt/silcpkcs.[ch].
6232 Added also silc_pkcs_[un]register[_default] functions.
6233 Removed the data_context from the PKCS API.
6235 * Added silc_hmac_register_default function to register default
6236 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
6237 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
6238 to unregister all hmacs at once.
6240 * Register the default ciphers, hash functions, PKCSs and HMACs
6241 if client's configuration file does not exist. The affected
6244 * The client did not load the hash functions from the SIM
6245 modules at all. Added support for this. Affected file is
6246 silc/clientconfig.c.
6248 * When decoding public key with silc_pkcs_public_key_decode, check
6249 the supported algorithm only if PKCS are registered. Affected
6250 file lib/silccrypt/silcpkcs.c. The same was done with the
6251 silc_pkcs_private_key_decode.
6253 * Fixed the SILC List routines to keep the list always in order.
6254 It used to change the list's order when traversing the list but
6255 not it preserves the order. Affected file lib/trq/silclist.h.
6257 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6259 * Added the client library to use the SilcSocketConnection's
6260 reference counter (by silc_socket_dup) to prevent the bug that
6261 the socket object may be freed underneath async operation.
6263 * The name resolv library checking fixes in the configure.in.pre.
6266 * Created new version of the protocol drafts for future
6267 development. The -03 drafts are the ones that will be changed
6268 in the trunk now and the -02 will remain as they are.
6270 * Send list of CUMODE notifys to the router when announcing
6271 the channel users to the router. Affected file silcd/server.c.
6272 If the router receiving channel founder CUMODE for a channel
6273 that already has channel founder it will send CUMODE notify
6274 to the sender to remove the channel founder rights from the
6275 announced client. Affected file silcd/packet_receive.c.
6277 * The CUMODE notify may now use Server ID as well as the entity
6278 who changes the mode. Updated protocool specs.
6280 * Updated INSTALL and README files.
6282 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6284 * New web pages in the http://silc.pspt.fi. The pages was
6289 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6291 * Implemented the [DenyConnectin] config section in the server.
6292 Added silc_server_config_denied_conn to check whether incoming
6293 connection is denied. Affected file silcd/serverconfig.[ch].
6295 * Do not check the ports when checking the incoming configuration
6296 data if the port is 0, meaning any. Affected file is
6297 silcd/serverconfig.c.
6299 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6301 * Fixed buffer overflow in silc_string_compare in the file
6302 lib/silcutil/silcutil.c.
6304 * Fixed double free in silc_server_command_leave in the file
6307 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6309 * Fixed the version checking in the server. Affected file is
6312 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6314 * Fixed the configuration data fetching when accepting new
6315 connections in the server. Affected file silcd/server.c.
6317 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6319 * Added `sender_entry' argument to the function
6320 silc_server_packet_relay_to_channel so that we can check
6321 whether some destination actually belongs to the same route
6322 the sender belongs (ie, we must not resend the packet to the
6323 sender). Affected file silcd/packet_send.[ch].
6325 * Added `servername' field to the SilcClientEntry in the server
6326 to hold the name of the server where client is from. Affected
6327 file is silcd/idlist.h.
6329 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6331 * Moved the channel message encrypting in the router betwen
6332 router connections from silc_server_channel_message to the
6333 silc_server_packet_relay_to_channel since we want to check
6334 whether we have anybody channel before encrypting anything.
6335 Affected files silcd/packet_[receive/send].c.
6337 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6339 * Fixed the [AdminConnection] server config section to support
6340 multiple entries. Affected file silcd/serverconfig.c.
6342 * Added support into the server to check the validity of the
6343 incoming connection before executing any KE or authentication
6346 * The connection configuration is now saved to the KE and
6347 connection auth protocol contexts and not fetched anymore in
6348 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
6350 * The local hosts listenning address and port is also resolved
6351 now when starting the server. We want to have the socket object
6352 to include the real address and port for the listener. Added
6353 new function silc_net_check_local_by_sock into the files
6354 lib/silcutil/silcnet.[ch].
6356 * Fixed a broadcast bug in server -> do not broadcast if we
6359 * Fixed a routing bug. Do not route broadcast packets ever.
6360 Broadcast packets must be processed always and not routed since
6361 they may be destined to some other host than yourself and thus
6362 would get routed without no good reason. Affected file is
6365 * Added function silc_server_config_is_primary_route to check
6366 whether primary router connection has been configured (a router
6367 configuration that we are initiating). If there is not, we
6368 will assume that there is only two routers in the SILC network
6369 and we will use the incoming router connection as our primary
6370 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
6372 * Changed the order of the broadcasting. Broadcast _after_ the
6373 packet has been processed not before. Affected file is
6376 * Fixed a [ClientConnection] parsing bug. The port was never
6377 parsed correctly thus resulting to port 0. Affected file
6378 silcd/serverconfig.c.
6380 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
6381 argument and did not set the broadcast packet flag. Affected
6382 file silcd/packet_send.c. Fixed same bug in the function
6383 silc_server_send_notify as well.
6385 * If we receive NEW_ID packet for our own ID in the server, ignore
6388 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6392 * Removed the nickname from the Private Message Payload.
6393 Updated the code and the protocol specs.
6395 * Updated protocol specs for submitting to the IETF.
6397 * Tweaked the Random Number Generator a bit. Affected file
6398 lib/silccrypt/silcrng.c. Exported a new function
6399 silc_rng_[global]_add_noise which can be used to add more
6402 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6404 * Do not parse packets with different timeout when protocol
6405 is active -> may cause problem with rekey. Affected file
6408 * When server receives signoff notify it must not create
6409 new channel key if the client is on any channels since the
6410 sender of the signoff notify will create it.
6412 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6414 * Added printing of error messages during SKE protocol from the
6415 failure packet sent by server during SKE. Affected file
6418 * Removed the client's failure_callback handling with timeout
6419 and handle it immediately when received.
6421 * The SKE library returned wrong type in SUCCESS and FAILURE
6422 packets. They must be 32 bit MSB not 16 bit MSB.
6424 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6426 * Ok, rewrote the logic of the re-key and now it seems to work.
6427 I tested it on high traffic with frequent re-keys without
6428 problems. Added hmac_receive (and renamed hmac to hmac_send)
6429 in SilcClientConnection in lib/silcclient/client.h and
6430 in SilcIDListData in silcd/idlist.h. Also, removed the
6431 SilcPacketParserContext's cipher and hmac fields as they are
6432 not needed anymore and actually caused some problems when
6433 the ciphers and hmac's changed underneath the packet parser.
6435 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6437 * If re-key protocol is active then process the incoming packets
6438 synchronously since we must assure that icoming packets encrypted
6439 with the old key is processed before the new keys is set to
6440 use. This is true other packets than for REKEY packets.
6441 Affected file silcd/server.c. The same was done to client library
6442 as well, affected file lib/silcclient/client.c.
6444 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6446 * Fixed bug in client and server to accept the force send if
6447 the packet is send from silc_[server/client]_packet_process
6448 function. Otherwise the packets are never delivered, oops.
6450 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6452 * Disable force sending of packets when REKEY protocol is active.
6453 We must assure that no packet is sent directly when rekey is
6454 performed. All packets must be sent through packet queue.
6455 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
6456 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
6457 function is silc_[server/client]_packet_send_real to check
6460 * Replaced the SIM paths from example config files to
6461 /usr/local/modules. Also, make install creates now
6462 /usr/local/silc/logs directory to hold all the SILC server
6465 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6467 * Made the configure.in.pre work on Solaris. Patch by salo.
6469 * Made all ciphers compatible with non-x86 machines. Defined
6470 CBC mode macros into lib/silccrypt/ciphers_def.h.
6472 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6474 * Fixed the make install.
6476 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6478 * When MAC computation fails the silc_packet_decrypt returned 0
6479 even though it was supposed to return -1. Fixed this. The
6480 affected file is lib/silccore/silcpacket.c.
6482 * Do not replace the config files in /etc/silc (in make install)
6483 if they already exist. Affected file ./Makefile.am.
6485 * Do not send re-key packets immediately but through packet queue.
6486 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6488 * Changed silc_net_check_host_by_sock to return FALSE if the
6489 IP/DNS could not be resolved. Though, it returns the IP address
6490 now even if it could not resolve it (but returns also FALSE).
6491 Affected file lib/silcutil/silcnet.[ch].
6493 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6495 * Added silc_pkcs_decode_identifier to decode the public key's
6496 identifier. Affected file lib/silccrypt/silpkcs.[ch].
6497 Added also silc_pkcs_free_identifier. Added also new context
6498 SilcPublicKeyIdentifier.
6500 * Added -S option to the silc client. It is used to dump the
6501 contents of the specified public key file.
6503 * Changed the PKCS api to return the public key length when
6504 setting the public key.
6506 * Fixed a fatal bug in the public and private key file loading.
6507 Affected file lib/silccrypt/silcpkcs.c.
6509 * Execute the packet parsing for client with zero (0) timeout
6510 if the protocol is active. Affected file silcd/server.c.
6512 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6514 * Made the key generation options to the silcd program. Added
6515 -C option, equivalent to client's option.
6517 * Added new [ServerKeys] config section to the server. It
6518 configures the server's public and private key.
6520 * Defined generic Public Key Payload into the protocol
6521 specification to send specific type of public keys and
6524 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6525 public key or certificate.
6527 * Implemented the GETKEY command to the server and to the
6528 client library and on user interface.
6530 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6532 * Made preliminary `make install' work.
6534 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6536 * Added SilcServerRekey context into silcd/idlist.h.
6538 * Added the PFS support as defined in the specification to the
6539 SKE protocol. Affected files lib/silcske/*.c.
6541 * Added `ske_group' field to the SilcServerRekey context to hold
6542 the number of the SKE group that is used with PFS in re-key.
6543 Affected file silcd/idlist.h.
6545 * Added PFS re-key support to the server. Affected file is
6548 * Added silc_protocol_cancel to cancel execution of the next
6549 state of the protocol. Affected file is
6550 lib/silccore/silcprotocol.[ch].
6552 * Added the re-key support with and without PFS to the client
6553 library. Re-key is performed once in an hour, by default.
6555 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6556 Added silc_client_rekey_callback and silc_client_rekey_final.
6557 Affected files are lib/silcclient/protocol.[ch] and
6558 lib/silcclient/client.[ch].
6560 * Removed the `hmac_key' and `hmac_key_len' fields from the
6561 SilcClientConnection structure; not needed. Affected file is
6562 lib/silcclient/client.h.
6566 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6568 * Do not ask whether user wants to use the negotiated private key
6569 for private messages, just use it. Affected file is
6570 silc/local_command.c.
6572 * Added `send_enc_key' and `enc_key_len' fields to the
6573 SilcIDListData structure since they are needed in the re-key
6574 phase. Affected file is silcd/idlist.[ch].
6576 * Implemented the simple re-key protocol into the server.
6577 Affected files silcd/server.c and silcd/protocol.[ch]. The
6578 re-key will be performed once in an hour, by default.
6580 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6581 Added silc_server_rekey, silc_server_rekey_callback and
6582 silc_server_rekey_final.
6584 * Removed Tunneled flag from the protocol. Updated the code
6585 and the specifications.
6587 * Adde `pfs' field to the SilcIDListData to indicate whether
6588 the PFS is to be performed in the re-key. Affected file is
6591 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6593 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6594 int64 of at least the xintXX size. If void * is less that 4
6595 bytes uint32 * will be used. Defined bool as boolean.
6597 * Changed _ALL_ unsigned long and unsigned int to uint32,
6598 unsgined short to uint16 in the source tree.
6600 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6601 not handle clients that has entry->data.registered == FALSE.
6602 They are not in the network anymore. Affected file is
6605 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6607 * Implemented the sending of the SERVER_SIGNOFF notify in the
6608 server. Affected file is silcd/server.c.
6610 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6611 Added also silc_notify_payload_encode_args into the
6612 lib/silccore/silcnotify.[ch].
6614 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6615 Affected file silcd/packet_receive.c.
6617 * Implemented the SERVER_SIGNOFF notify handling in the client
6618 library. Affected file lib/silcclient/client_notify.c. Also,
6619 implemnted the printing of the SERVER_SIGNOFF info to the
6620 application. Affected file silc/client_ops.c.
6622 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6623 if the deleting was successful. Affected file silcd/idlist.[ch].
6625 * Added support for public key authentication in the connection
6626 authentication protocol in the client library. Affected file
6627 lib/silcclient/protocol.c.
6629 * Changed the server's silc_idlist_get_clients_by_* interface
6630 to support already allocated array so that new entries may be
6631 added to pre-allocated array. Affected file silcd/idlist.[ch].
6632 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6633 and command replies.
6635 * All command reply functions in the server now calls the
6636 pending command callback even if error occured. This way the
6637 error will be delivered to the client as well. Affected files
6638 silcd/command.c and silcd/command_reply.c.
6640 * Fixed INFO command to return local server's info if no server
6641 was provided. Affected file lib/silcclient/command.c.
6643 * Removed RESTART command for good. Updated the code and the
6646 * Rewrote parts of the task system. It is a bit simpler now.
6647 Removed unsued task priorities. The affected files are
6648 lib/silcutil/silctask.[ch].
6650 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6652 * Moved the USERS printing from the library to the application.
6653 Affected files lib/silcclient/command.c and silc/client_ops.c.
6655 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6659 * Added channel key re-key support. The re-key is perfomed
6660 only by the router and is done once in an hour. Added `rekey'
6661 field to the SilcChannelEntry in the server. Affected files
6662 silcd/server.c and silcd/idlist.h.
6664 * Added silc_task_unregister_by_context into the file
6665 lib/silcutil/silctask.[ch].
6667 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6669 * Added SILC_UMODE_GONE mode to indicate when the client is not
6670 present in the SILC network. Added also support to the local
6671 command AWAY that will set this mode. Added support of showing
6672 "xxx is gone" in WHOIS command. The USERS command shows the
6673 gone status as well.
6675 * Fixed setting server and router operator privileges in the
6676 server's UMODE command. Affected file silcd/command.c.
6678 * Merged the SKE KE1 and KE2 payloads into one payload. The
6679 new KE payload is equivalent to the old KE2 payload.
6681 Cleaned up the SKE Start Payload parsing. It now uses the
6682 simple buffer unformatting to do the parsing. A lot faster
6685 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6686 to the SKE that is used to indicate whether both of the SKE
6687 parties should perform authentication. By default only the
6688 responder performs authentication. By setting this flag also
6689 the initiator must do authentication. By default it is unset
6690 since in normal SKE case, client to server connection, only
6691 the responder should do authentication. When doing SKE between
6692 two clients both should perform authentication. Updated the
6693 code and the protocol specs.
6695 * A little fix to IDENTIFY command in the server. Search the
6696 client first by hash not nickname. Affected file is
6699 * Fixed the silc_client_close_connection to support closing
6700 the client to client connections wihtout deleting too much
6701 data. Affected file lib/silcclient/client.c.
6703 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6704 are received if protocol used to be active but is not anymore
6705 the application would crash due to NULL pointer dereference.
6706 Affected files silcd/server.c and lib/silcclient/client.c.
6708 * Added `hash' field to the SilcClientConnection to include
6709 the hash function negotiated in the SKE protocol.
6711 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6712 to set the channel founder authentication data. A client can
6713 claim the founder rights later by providing the authentication
6714 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6715 This way the channel founder can regain the channel founder
6716 privileges even it is left the channel. This works only on
6717 local server and the client must be connected to the same
6718 server to be able to regain the founder rights. Updated the
6719 protocol specs accordingly.
6721 Added support to the CMODE command in the client to set the
6722 founder auth data. Read the README to see how to set it.
6724 Added support to the CUMODE command to claim the founder
6725 rights. Read the README to see how to do it.
6727 Added support for the founder authentication to the Channel
6728 Entry in the server. Affected file silcd/idlist.h.
6730 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6731 server's CMODE command. Affected file silcd/command.c.
6733 * Added the following new functions into lib/silccore/silcauth.[ch]:
6734 silc_auth_get_method and silc_auth_get_data.
6736 * The server now saves the remote hosts public key to the
6737 SilcIDListData pointer. Affected file silcd/protocol.c.
6739 * The normal server now does not remove the channel entry from
6740 the cache if the founder authentication data is set. It used
6741 to remove it if the founder was the last one on the channel on
6742 the server and left the channel. The auth data is saved and
6743 if the channel is re-joined later the old entry is used with
6744 the old auth data. Affected files silcd/command_reply.c and
6747 * Removed the `pkcs' field from the SilcIDListData structure
6748 in the server; it is not used. Affected file silcd/idlist.h.
6750 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6752 * Fixed packet processing on slow links. Partial packets were
6753 never re-processed because the incoming data buffer was cleared
6754 by the application. Application must not directly clear the
6755 sock->inbuf, the packet processing routines handle it. Fixed
6756 this in client library and in server.
6758 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6760 * Fixed the WHOIS and IDENTIFY send reply function to really
6761 check whether to send list or just one entry. Affected file
6764 * Cleaned up the LEAVE command's channel key distribution. The
6765 affected file silcd/command.c.
6767 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6768 can enforce the channel mode as well. In that case the ID
6769 includes the ID of the server. The code now enforces the
6770 mode change if the router have different mode than the server.
6772 * The notify client operation with CMODE_CHANGE notify can now
6773 return NULL client_entry pointer if the CMODE was not changed
6774 by client. Application must check for this.
6776 * Added <Server ID> argument to INFO command to support server
6777 info fetching by Server ID.
6779 * Added silc_server_announce_get_channel_users to get assembled
6780 packets of channel users of the specified channel. Affected
6781 file silcd/server.[ch].
6783 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6784 was freed underneath the ID Cache.
6786 * Re-announce clients when the server received CHANNEL_CHANGE
6787 notify from the router. Affected file silcd/packet_send.c.
6789 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6791 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6792 crashed since it did not handle the fact that there is no cipher
6793 called "3" and didn't check the error condition. Now fixed.
6795 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6796 flag. It can be used to send message requests.
6798 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6800 * Implemented the RESTART command in the client.
6802 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6803 notice type messages. Added notice printing to the user
6806 * The channel keys are not re-generated if the channel's mode
6807 is PRIVKEY, ie private key on the channel exists. Affected
6808 files silcd/server.c and silcd/command.c.
6810 * Fixed a little bug in channel message delivery when channel
6811 private keys are set in the server. Affected file is
6812 silcd/packet_send.c.
6814 * Changed the setting on channel->on_channel = TRUE from the
6815 silc_client_save_channel_key to the JOIN command reply. The
6816 key payload is not received if the private channel key is set.
6817 Affected file lib/silcclient/command_reply.c and the
6818 lib/silcclient/client_channel.c.
6820 * When the CMODE_CHANGE notify is sent and the channel private
6821 key mode is removed the channel key must be re-generated in
6822 other cells as well. Added this support for the router in the
6823 silcd/packet_receive.c.
6825 * Added new local command NOTICE to send notice message on
6826 channel. Affected file silc/local_command.[ch].
6828 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6830 * Added new local command ME to the client. It is used to send
6831 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6832 some action. Affected file silc/local_command.[ch].
6834 * Changed channel_message and private_message client operations
6835 to deliver the message flags to the application. Added also
6836 the `flags' arguments to the silc_client_send_channel_message
6837 and silc_client_send_private_message functions. Affected file
6840 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6842 * Redefined the Private Message Payload to support private message
6843 keys and to support the new private message flags. Updated
6844 the protocol specs. Flags makes it possible to have for example
6845 CTCP style messages.
6847 * Added new type SilcPrivateMessagePayload and defined an API
6848 for it in the lib/silcclient/silcprivate.[ch].
6850 * Tested private message private keys successfully. Tested the
6851 private message key set, unset and list commands with the new
6854 * Redefined the Channel Message Payload to include the channel
6855 message flags (equal with private message flags) to support
6856 for example CTCP style messages.
6858 * Defined some of the message (for channel and private message)
6859 flags. Updated the protocol specs and added the flags to the
6860 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6862 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6864 * Added SilcKeyAgreementStatus type to the key agreement routines
6865 to indicate the current status and error if one occured.
6866 The status types are defined in the lib/silcclient/silcapi.h.
6868 * Added new local command KEY that is used to set and unset private
6869 keys for channels, set and unset private keys for private messages
6870 with remote clients and to send key agreement requests and
6871 negotiate the key agreement protocol with remote client. The
6872 key agreement is supported only to negotiate private message keys,
6873 it currently cannot be used to negotiate private keys for channels,
6874 as it is not convenient for that purpose.
6876 * Fixed a minor pending callback setting bug in the function
6877 silc_client_get_client_by_id_resolve, now the function works.
6878 Affected file lib/silcclient/idlist.c.
6880 * Added function silc_net_get_local_port to get local bound
6881 port by socket. Added to lib/silcutil/silcnet.[ch].
6883 * Added `sockets' and `sockets_count' fields to the SilcClient
6884 object. They hold the sockets of the listenning sockets in
6885 the client. Listenning sockets may be for example the key
6886 agreement server. Affected file lib/silcclient/client.[ch].
6887 Added functions the silc_client_add_socket and the
6888 silc_client_del_socket. They are exported to the application
6891 * Added ~./silc/clientkeys to support other client's public keys.
6893 * Renamed verify_server_key client operation to verify_public_key
6894 and added one argument to indicate the type of the connection
6895 (server, client etc.).
6897 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6899 * Added silc_server_connection_auth_request to handle the
6900 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6901 silcd/packet_receive.[ch].
6903 * Added silc_server_send_connection_auth_request into the
6904 silcd/packet_send.c to send the connection auth request packet.
6906 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6909 * Fixed the public key authentication in responder side in the
6910 server. The `auth_data' pointer includes the SilcPublicKey
6911 not the path to the public key. Affected file silcd/protocol.c.
6913 * Implemented the public key authentication in the initiator side
6914 in the server. Affected file silcd/protocol.c.
6916 * Removed the [RedirectClient] config section from the server
6917 configuration. Is not needed and I don't want to implement it.
6919 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6921 * Cleaned up the CMODE command in the server. It now works
6922 correctly and supports all the modes defined in the protocol.
6923 Affected file is silcd/command.c.
6925 * Added `hmac_name' field to the SilcChannelEntry in the server
6926 to hold the default HMAC of the channel. It can be set when
6927 creating the channel (with JOIN command). Affected files
6930 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6931 type to indicate the change of the current cipher and hmac
6932 on the channel. Client can safely ignore the <cipher> argument
6933 (if it chooses to do so) since the CHANNEL_KEY packet will
6934 force the channel key change anyway. The <hmac> argument is
6935 important since the client is responsible of setting the new
6936 HMAC and the hmac key into use.
6938 * Fixed the CMODE command in the client library as well.
6940 * Tested CMODE command in router environment successfully.
6942 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6944 * Show the version of the remote client (or server) when connecting
6945 to the server. It is logged to the log file. Affected file
6946 is silcd/protocol.c.
6948 * Fixed the KILLED notify handling in the client library. The
6949 client must be removed from all channels when receiving the
6952 Also, do not remove the client entry when giving the KILL
6953 command but when the KILLED notify is received.
6955 * Removed silc_idlist_find_client_by_nickname from the server.
6956 Not needed anymore. Affected files silcd/idlist.[ch].
6958 * Implemented the CHANNEL_CHANGE notify type handling to the
6959 server. Affected file silcd/server.c.
6963 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6965 * Added silc_server_send_notify_invite to send the INVITE
6966 notify between routers.
6968 * Implemented the INVITE command correctly to the server.
6970 * Implemented the INVITE notify type handling in the server.
6972 * Implemented the INVITE command to the client library and on the
6975 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6977 * Added function silc_server_get_client_resolve to find the
6978 client entry by ID from all ID lists and then resolve it
6979 (using WHOIS) if it cannot be found. Affected file is
6982 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6984 * Implemented the BAN command to the client library.
6986 * The JOIN command in the server now checks the invite list
6989 * Changed the silc_command_reply_payload_encode_va and the
6990 silc_command_payload_encode_va to support that if argument is
6991 NULL it ignores and checks the next argument. Affected file
6992 lib/silccore/silccommand.c.
6994 * Added silc_server_send_notify_ban to send the BAN notify
6995 type between routers.
6997 * Chaned the silc_notify_payload_encode to support that if
6998 argument is NULL it ignores and checks the next argument.
6999 Affected file lib/silccore/silcnotify.c.
7001 * Tested ban lists in router environment successfully.
7003 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7005 * Implemented BAN command to the server, in silcd/command.[ch].
7007 * Removed the BAN and INVITE_LIST modes from the CMODE command
7010 * Added function silc_string_match to regex match two strings.
7011 Affected files lib/silcutil/silcutil.[ch].
7013 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7015 * Redefined parts of the SilcChannelEntry in the server to support
7016 the new ban and invite lists.
7018 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7020 * Redefined the INVITE command. The same command can be used to
7021 invite individuals to the channel but also to manage the invite
7022 list of the channel (to add to and remove from the invite list).
7023 Updated the protocol specs.
7025 * Added new command SILC_COMMAND_BAN that can be used to manage
7026 the ban list of the channel. Updated the protocol specs.
7028 * Removed the channel modes: the SILC_CMODE_BAN and the
7029 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
7030 in the CMODE command. The equivalent features are now available
7031 using INVITE and BAN commands. Updated the protocol specs.
7033 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
7034 in the network about change in the current ban list. The notify
7035 type is not used by the client.
7037 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
7038 support the invite lists.
7040 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7042 * Added new function silc_string_regexify that converts string
7043 including wildcard characters into regex string that can
7044 be used by the GNU regex library. Added into the file
7045 lib/silcutil/silcutil.[ch].
7047 Added silc_string_regex_combine to combine to regex strings
7048 into one so that they can be used as one regex string by
7049 the GNU regex library. Added into the file
7050 lib/silcutil/silcutil.[ch].
7052 Added silc_string_regex_match to match two strings. It returns
7053 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
7055 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7057 * Imported GNU regex to the soruce tree into lib/contrib.
7058 Fixed some compiler warning from the regex.c.
7060 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7062 * Fixed MOTD command in the server to work in router environment.
7064 * Fixed the MOTD command in the client library to support
7065 the server argument in the command.
7067 * Added `nickname_len' argument to the silc_idlist_add_client
7068 in the server, as the `nickname' argument may be binary data
7071 * Added silc_idlist_get_channels to return all channels from
7074 * Implemented LIST command to the server. Affected file is
7077 * Implemented the LIST command to the client library and on the
7080 * Added [<user count>] argument to the LIST command reply.
7081 With private channels the user count is not shown.
7083 * Updated TODO and README.
7085 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7087 * The client entry's data.registered must be TRUE even with
7088 global client entry on global client list. The data.registered
7089 is used to check whether the client is anymore in the network,
7090 for example with WHOWAS command so it must be valid.
7092 * Fixed the WHOWAS command in the server. It now actually works
7093 in router environment. Added function into silcd/command_reply.c
7094 silc_server_command_reply_whowas_save.
7096 * Added silc_idlist_purge function to the silcd/idlist.c
7097 to periodically purge the ID Cache.
7099 * Fixed INFO command in the server. It works now in router
7100 environment. Added <server name> argument to the INFO command
7101 reply. Updated the protocol specs.
7103 * Fixed minor bug in silc_idcache_purge to not purge if the
7104 expire value is zero.
7106 * Fixed various bugs in WHOIS and IDENTIFY command handling as
7107 they were buggy because of the WHOWAS information.
7109 * Fixed local command MSG to handle the async resolving of
7110 the remote client properly. It used to fail the first MSG.
7111 Affected file silc/local_command.c.
7113 * Added `data_len' field to SilcIDCache context.
7115 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7117 * Update TODO. Todo in commands in the server.
7119 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7121 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
7122 used by routers as broadcast packet to inform other routers
7123 about the changed user mode.
7125 Implemented the notify handling in the server. Affected file is
7126 silcd/packet_receive.c. Added the function
7127 silc_server_send_notify_umode to the silcd/packet_send.[ch].
7129 * Added new generic Channel Payload and deprecated the New Channel
7130 Payload. The New Channel Payload is now the generic Channel
7133 * Added new argument `mode' to the silc_server_send_new_channel
7134 as it is required in the Channel Payload now.
7136 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
7137 and created a new and real SilChannelPayload to represent the
7138 new generic Channel Payload. Implemented the encode/decode
7139 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
7141 * Added silc_server_get_client_channel_list to return the list
7142 of channels the client has joined for WHOIS command reply.
7143 Affected file silcd/server.[ch].
7145 * Implemented the channel list sending in the WHOIS command reply
7146 in server and in the client.
7148 Implemented the channel list displaying on the user interface
7149 as well. Affected file silc/client_ops.c.
7151 * Added silc_channel_payload_parse_list to parse list of Channel
7152 Payloads. It returns SilcDList list of SilcChannelPayloads.
7153 Client for example can use this function to parse the list of
7154 channels it receives in the WHOIS command reply. The caller
7155 must free the list by calling silc_channel_payload_list_free.
7156 Affected files lib/silccore/silcchannel.[ch].
7158 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7160 * Added one new argument <user mode> to the WHOIS command reply
7161 to return the mode of the user in SILC. Updated the protocol
7164 Implemented it to the server and client.
7166 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7168 * Fixed the mode printing on the user interface on joining.
7169 Affected file silc/client_ops.c.
7171 * Implemented the UMODE command and user modes in general to the
7172 client library and to the user interface.
7174 * Implemented the UMODE command to the server.
7176 * The server now sends UNKNOWN_COMMAND error status if client sends
7177 unknown command. Affected file silcd/command.c.
7179 * All server commands now handle the command identifier the right
7180 way when sending the command reply to the client. The client can
7181 use to identify the command replies with the identifier.
7183 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7185 * Added silc_server_get_client_route to resolve the route to
7186 the client indicated by the client ID. Affected file is
7189 * Added silc_server_relay_packet as general function to relay
7190 packet to arbitrary destination. This deprecates functions
7191 like _send_private_message_key, _relay_notify etc. Affected
7192 file is silcd/packet_send.[ch].
7194 Removed silc_server_send_key_agreement,
7195 silc_server_send_private_message_key and
7196 silc_server_packet_relay_notify functions from the file
7197 silcd/packet_send.[ch].
7201 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
7202 server. Affected file silcd/packet_receive.[ch].
7204 * Implemented the KILL command to the client. Implemented the
7205 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
7206 Affected files lib/silcclient/command[_reply].c and
7207 lib/silcclient/client_notify.c. Implemented the KILL notify
7208 printing in the user inteface.
7210 * Fixed a lot silc_parse_nick memory leaks from the client
7211 library in the file lib/silcclient/command.c.
7213 * Changed the silc_server_send_notify_on_channels's `sender'
7214 argument from SilcSocketConnection to SilcClientEntry to
7215 check the sender as entry and not as connection object and not
7216 to send to the client provided as argument. The affected file
7217 is silcd/packet_send.[ch].
7219 * The notify packets that are destined directly to the client used
7220 to not to be processed by the server. Now changed that and the
7221 server processes all notify packets. After relaying the packet
7222 to the client the notify packet is processed in the server.
7224 * The silc_server_free_client_data now checks whether there is
7225 pending outgoing traffic for the client and purges the data to
7226 the network before removing the client entry.
7228 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7230 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
7231 an client is killed from the SILC Network. Updated the protocol
7234 Added new function silc_server_send_notify_killed to the
7235 silcd/packet_send.[ch].
7237 * Added function silc_server_packet_relay_notify to relay notify
7238 packets that are destined directly to a client. In this case
7239 the server does not process the notify packets but merely relays
7240 it to the client. Affected file silcd/packet_send.[ch].
7242 Added also silc_server_packet_process_relay_notify to check
7243 whereto relay the notify. Affected file is
7244 silcd/packet_receive.[ch].
7246 * Implemented the KILL command to the server.
7250 * Added the backup schema desgined last fall to the protocol
7251 specs for everyone to see. The specification is in the
7252 *-spec-xx.txt draft and the packet type definitions for the
7253 backup routers is in *-pp-xx.txt draft. Thusly, added also
7254 new packet type SILC_PACKET_CELL_ROUTERS.
7256 * A big security problem in the implementation discovered. The
7257 signoff of an client did not cause new channel key generation
7258 which it of course should've done. The channel keys must be
7259 always re-generated when client leaves (or signoffs) the channel.
7260 The silc_server_remove_from_channels funtion now handles
7261 the channel key re-generation.
7263 * Added `sender' argument to the silc_server_send_notify_on_channels
7264 to not to send the client provided as argument. Affected file
7265 silcd/packet_send.[ch].
7267 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7269 * Implemented OPER and SILCOPER commands into the server and
7272 * Added silc_auth_verify and silc_auth_verify_data to verify
7273 the authentication directly from the authentication payload.
7274 It supports verifying both passphrase and public key based
7275 authentication. Affected file lib/silccore/silcauth.[ch].
7277 * Added `hash' field to the SilcIDListData structure. It is the
7278 hash negotiated in the SKE protocol. Affected file is
7281 * Slight redesigning of the SilcAuthPayload handling routines.
7282 Do not send SilcPKCS but SilcPublicKey as argument.
7284 * Implemented the public key authentication support to the
7285 serverconfig. The public key is loaded from the provided path
7286 and saved as authentication data to void * pointer. Thus,
7287 changed the unsigned char *auth_data to void *auth_data;
7289 * Fixed SHUTDOWN command to send the reply before the server
7290 is shutdown. :) Affected file silcd/command.c.
7292 * Fixed fatal bug in CONNECT command. The hostname was invalid
7293 memory and server crashed. Affected file silcd/command.c.
7295 * Fixed fatal bug in CLOSE command. The server_entry became
7296 invalid but was referenced later in the command. Affected file
7299 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7301 * Fixed fatal bug in failure packet handling. Server ignored
7302 the failure and thus crashed when it came.
7306 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7308 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
7309 that the command may be executed only once in (about) 2 seconds.
7310 The old SILC_CF_LAG flag is same but allows command bursts up
7311 to five before limiting.
7313 Added the support for CF_LAG and CF_LAG_STRICT flags to the
7314 server code. Various commands now includes the CF_LAG_STRICT
7315 flag to disallow any kind of miss-use of the command.
7317 * Fixed the silc_buffer_unformat to not to allocate any data
7318 if the length of the data is zero. It used to allocate the
7319 length + 1. Affected file lib/silcutil/silcbuffmt.c.
7321 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7323 * Changed the format of AdminConnection configuration section
7324 in the server. Added username of the admin to the format.
7325 Affected files silcd/serverconfig.[ch].
7327 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
7328 to return admin configuration data by host, username and/or
7331 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7333 * Implemented WHOWAS command to the server. Added the functions:
7335 silc_server_command_whowas_parse,
7336 silc_server_command_whowas_send_reply,
7337 silc_server_command_whowas_from_client and
7338 silc_server_command_whowas_from_server
7340 * Added <Client ID> argument to the WHOWAS command reply. Updated
7341 the protocol specs accordingly.
7343 * Implemented WHOWAS command and command_reply to the client
7346 Implemented the WHOWAS printing on the user interface.
7348 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7350 * Added new argument to the WHOWAS command reply, the real name.
7351 It is an optional argument. Updated the protocol specs.
7353 * Added SilcIDCacheDestructor callback that is registered when
7354 the SilcIDCache is allocated. The callback is called when
7355 an cache entry in the ID Cache expires, or is purged from the
7356 cache. Added into lib/silccore/idcache.[ch].
7358 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
7359 to destruct the client entries when the cache entry expires.
7360 Other ID Cache's in server and in the client library ignores
7363 * If the ID Cache entry's `expire' field is zero then the entry
7364 never expires. Added boolean `expire' argument to the
7365 silc_idcache_add function in the lib/silccore/idcache.[ch].
7366 If it is TRUE the default expiry value is used.
7368 * Added silc_server_free_client_data_timeout that is registered
7369 when client disconnects. By default for 5 minutes we preserve
7370 the client entry for history - for WHOWAS command.
7372 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7374 * Added support to the server to enforce that commands are not
7375 executed more than once in 2 seconds. If server receives
7376 commands from client more frequently, timeout is registered
7377 to process the commands. Affected file silcd/command.c.
7378 Added new function silc_server_command_process_timeout.
7380 * Changed NICK_NOTIFY handling in client library to check that
7381 if the client's nickname was changed, so there is no need to
7382 resolve anything from the server.
7384 * Removed error printing from the WHOIS and IDENTIFY commands.
7385 If error occurs then it is ignored silently in the client library.
7386 The application, however, may map the received error to
7387 human readable error string. The application currently maps
7388 the NO_SUCH_NICKNAME error to string.
7390 * Made the command status message public to the application. Moved
7391 them from lib/silcclient/command_reply.c to
7392 lib/silcclient/command_reply.h. The application can map the
7393 received command status to the string with the
7394 silc_client_command_status_message function.
7396 * Added check to the server to check that client's ID is same
7397 as the Source ID in the packet the client sent. They must
7400 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7402 * Added dist-bzip hook to the Makefile.am to make bzip2
7403 compressed distributions.
7405 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7407 * Server now enforces the maximum length for the nickname and
7408 the channel as protocol specification dictates. 128 bytes for
7409 nickname and 256 bytes for channel name.
7411 * Moved the WHOIS printing to the application. The client libary
7412 does not print out the WHOIS information anymore, the application
7413 must do it. Renamed silc_client_command_reply_whois_print to
7414 the silc_client_command_reply_whois_save.
7416 The client's idle time is also sent to the application now, and
7417 the idle is shown on screen.
7419 * Added silc_client_command_reply_identify_save to save the
7420 received IDENTIFY entries.
7422 * Do not check for channel private keys in message sending and
7423 reception if the channel does not have the PRIVKEY mode set.
7424 Affected file lib/silclient/client_channel.c.
7426 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7428 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
7429 just surfaced after chaning the JOIN procedure.
7431 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7433 * Added silc_client_get_clients_by_list to get client entries
7434 from Client ID list, that is returned for example by JOIN
7435 and USERS command replies. The application should use this
7436 function for example when JOIN command reply is received to
7437 resolve the clients already on the channel (library does not
7438 do that anymore as USERS command reply is not used in the JOIN
7439 procedure anymore). Affected files lib/silcclient/silcapi.h and
7440 lib/silcclient/idlist.c.
7442 * JOIN command reply and USERS command reply returns now SilcBuffer
7443 pointers instead of unsigned char pointers when returning
7444 the client list and mode list.
7446 * Added <Client ID> argument to the JOIN command reply, mainly
7447 for the server to identify for which client the command was
7448 originally sent. Updated protocol specs accordingly.
7450 * Added SilcDlist private_key pointer to the SilcChannelEntry
7451 in the client to support the channel private keys. Affected
7452 file is lib/silcclient/idlist.h.
7454 * Added SilcChannelPrivateKey argument to the function
7455 silc_client_send_channel_message so that application can choose
7456 to use specific private ke if it wants to. If it is not provided,
7457 the normal channel key is used, unless private keys are set.
7458 In this case the first (key that was added first) is used
7459 as the encryption key.
7461 * Implemented the support for channel private key handling.
7462 Implemented the following functions:
7464 silc_client_add_channel_private_key,
7465 silc_client_del_channel_private_keys,
7466 silc_client_del_channel_private_key,
7467 silc_client_list_channel_private_keys and
7468 silc_client_free_channel_private_keys
7470 Affected file lib/silcclient/client_channel.c.
7472 * Added the support for the private keys in the channel message
7473 sending and encryption and in the message reception and
7474 decryption. Affected funtions are
7475 silc_client_send_channel_message and silc_client_channel_message.
7477 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7479 * Added SKE's key verify callback to the client library's
7480 KE protocol context. Affected files lib/silcclient/protocol.[ch].
7482 * Removed the statement that server (or router) must send USERS
7483 command reply when joining to the channel so that the client
7484 knows who are on the channel. Instead, the client list and
7485 client's mode list is now sent in the JOIN command reply to the
7486 client who joined channel. This is better solution.
7488 * Added function silc_server_get_users_on_channel and function
7489 silc_server_save_users_on_channel to the silcd/server.[ch].
7491 * Removed function silc_server_command_send_users from the
7494 * Do not show topic on the client library anymore. The topic is
7495 sent in the command reply notify to the application and the
7496 application must show the topic now.
7498 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7500 * Added client searching by nickname hash into the IDENTIFY and
7501 WHOIS commands in the server as they were clearly missing from
7502 them. Affected file is silcd/command.c.
7504 * Fixed a bug in private message receiving in the client library.
7505 The remote ID was freed and it wasn't supposed, now it is
7508 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7510 * Minor fix to the channel payload; allocate the data area, as it
7511 needs to be of specific length.
7513 * If the key agreement port is zero then the operating
7514 system will define the bound port. Affected files are
7515 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7517 * Added new function silc_channel_payload_decrypt into the file
7518 lib/silccore/silcchannel.[ch].
7520 * Moved the channel message etc, check from silc_packet_decrypt
7521 to applications. The library calls now a generic
7522 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7523 when the packet is either normal or special. This was done to
7524 allow more wide range of checking that was not allowed when
7525 the code was in library. Now applications can do virtually any
7526 checks to the packet and return to the library the decision how
7527 the packet should be processed. Affected files are
7528 lib/silccore/silcpacket.[ch].
7530 Added silc_server_packet_decrypt_check to the server and
7531 silc_client_packet_decrypt_check to the client library.
7533 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7534 to send with specified source and destination information.
7536 * Channel message delivery between routers was broken after the
7537 channel key distribution was fixed earlier. The channel key
7538 was used be to distributed to other routers as well which is not
7539 allowed by the protocol. Now this is fixed and channel keys
7540 really are cell specific and the channel message delivery between
7541 routers comply with the protocol specification.
7543 * Fixed various commands in server to check also the global list
7544 for the channel entry and not just the local list. The affected
7545 file silcd/command.c.
7547 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7549 * Added assert()s to buffer formatting and unformatting routines
7550 to assert (if --enable-debug) when error occurs. Affected
7551 file: lib/silcutil/silcbuffmt.c.
7553 * Changed to auto-reconnect to check whether the remote host is
7554 router and register the re-connect timeout if it is. It used
7555 to check that whether we are normal server, but router must do
7556 auto-reconnect with another router as well. Affected file
7559 * Removed the [<key len>] option from CMODE command as the cipher
7560 name decides the key length, nowadays. See the defined ciphers
7561 from the protocol specification.
7563 * Added [<hmac>] option to the CMODE command to define the HMAC
7564 for the channel. Added SILC_CMODE_HMAC channel mode.
7566 * Added [<hmac>] option for the JOIN command so that user can
7567 select which HMAC is used to compute the MACs of the channel
7570 * Added Hmac field to the Channel Message Payload. The integrity
7571 of plaintext channel messages are now protected by computing
7572 MAC of the message and attaching the MAC to the payload. The
7573 MAC is encrypted. Now, it is clear that this causes some
7574 overhead to the size of the packet but rationale for this is that
7575 now the receiver can verify whether the channel message decrypted
7576 correctly and also when private keys are set for the channel the
7577 receiver can decrypt the packet with several keys and check from
7578 the MAC which key decrypted the message correctly.
7580 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7581 lib/silccrypt/silccipher.[ch].
7583 * Added silc_hash_len to return the digest length into the
7584 lib/silcrypt/silchash.[ch].
7586 * Rewrote parts of Silc Channel Payload interface in the
7587 lib/silccore/silcchannel.[ch]. The encode function now also
7588 encrypts the packet and parse function decrypts it.
7590 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7592 * Fixed a minor formatting bug in the SKE's key material processing.
7593 It actually might have processed the keys wrong way resulting
7596 * Redefined the mandatory HMAC algorithms and added new algorithms.
7597 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7598 and hmac-md5 truncated to 96 bits. The mandatory is now
7599 hmac-sha1-96. Rest are optional (including the one that used
7600 to be mandatory). Rationale for this is that the truncated HMAC
7601 length is sufficient from security point of view and can actually
7602 make the attack against the HMAC harder. Also, the truncated
7603 HMAC causes less overhead to the packets. See the RFC2104 for
7606 * Added new [hmac] configuration section. The SKE used to use
7607 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7608 is of course wrong. The official names that must be proposed in
7609 the SKE are the ones defined in the protocol specification
7610 (hmac-sha1-96 for example). The user can configure any hmac
7611 using any hash function configured in the [hash] section. At
7612 least, the mandatory must be configured.
7614 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7616 * Added HMAC list to the SKE proposal list. It has now both
7617 hash algorithm list and HMAC list. This makes the protocol
7618 incompatible with previous versions. The SKE now seems to work
7619 the way it is supposed to work, for the first time actually.
7621 * Defined plain Hash algorithms to the protocol specification.
7624 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7626 * Implemented support for key agreement packets into the server.
7627 Added functions silc_server_key_agreement and
7628 silc_server_send_key_agreement. Other than these functions,
7629 server has nothing to do with this packet.
7631 * Added support for private message key packets into the server.
7632 Added functions silc_server_private_message_key and
7633 silc_server_send_private_message_key.
7637 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7638 called in the protocol's final callback instead in the END
7639 protocol state. This makes a little more sense and in the same
7640 time in client we can use the same protocol routines for normal
7641 key exchange and to key agreement packet handling as well.
7643 * Added to both client's and server's KE protocol context the
7644 SilcSKEKeyMaterial pointer to save the key material. We will
7645 bring the key material to the protocol's final callback by doing
7646 this. The final callback must free the key material.
7648 * Added SKE's packet_send callback into client's KE protocol
7649 context so that the caller can choose what packet sending function
7650 is used. This way we can use different packet sending when
7651 doing normal SKE when doing key agreement packet handling (in
7652 the key agreement packet handling we do not want to encrypt
7655 * Implemented the responder side of the key agreement routines
7656 in the client. The client can now bind to specified port and
7657 accept incoming key negotiation. The key material is passed
7658 to the application after the protocol is over.
7660 * Implemented the processing of incoming Key Agreement packet
7661 in the client. Added function silc_client_key_agreement to
7664 * Implemented the intiator side of the key agreement routines
7665 in the client. The client can now initiate key agreement with
7666 another remote client. The key material is passed to the
7667 application after the protocol is over.
7669 * Created client_keyagr.c to include all the key agreement
7672 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7673 SILC_TASK_CALLBACK except that it is not static.
7675 * Created client_notify.c and moved the Notify packet handling
7676 from the client.[ch] into that file.
7678 * Created client_prvmsg.c and moved all private message and
7679 private message key routines from the client.[ch] into that file.
7681 * Create client_channel.c and moved all channel message and
7682 channel private key routines from the client.[ch] into that file.
7684 * Changed silc_client_get_client_by_id_resolve to resolve with
7685 WHOIS command instead of IDENTIFY command, in the file
7686 lib/silclient/idlist.c.
7688 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7690 * Implemented the SKE's responder side to the Client library.
7692 * When FAILURE is received to the protocol do not trust it
7693 blindly. Register a timeout to wait whether the remote closes
7694 the connection as it should do it, only after that process the
7695 actual failure. This was changed to both client and server.
7697 * Added client_internal.h to include some of the structures
7698 there instead of client.h in lib/silcclient/.
7700 * Added function silc_task_unregister_by_callback to unregister
7701 timeouts by the callback function.
7703 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7705 * Some "Incomplete WHOIS info" errors has been appearing on the
7706 log files. Took away the entry->userinfo check from WHOIS
7707 reply sending. The entry->userinfo is now " " if client did not
7708 provide one. I thought this was fixed earlier but something
7709 is wrong still. Let's see if the error still appears.
7711 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7713 * Fixed a minor bug in the login when the channel key is
7714 re-generated in the server. It used to generate the key in
7715 wrong order and thus caused problems in the channel traffic.
7717 * Fixed a minor bug in channel key distsribution after
7718 KICK command. The key was not sent to the router even though
7721 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7723 * Added silc_ske_process_key_material_data as generic routine
7724 to process any key material as the SILC protocol dictates. The
7725 function is used by the actual SKE library but can be used by
7726 applications as well. This relates to the private message keys
7727 and the channel private keys since they must be processed the
7728 same way the normal SILC session keys. The protocol dictates
7729 this. Affected files: lib/silcske/silcske.[ch].
7731 Added also silc_ske_free_key_material to free the
7732 SilcSKEKeyMaterial structure.
7734 * Defined silc_cipher_set_key function to set the key for
7735 cipher without using the object's method function. The affected
7736 files: lib/silccrypt/silccipher.[ch].
7738 * Implemented silc silc_client_add_private_message_key,
7739 silc_client_add_private_message_key_ske,
7740 silc_client_del_private_message_key,
7741 silc_client_list_private_message_keys and
7742 silc_client_free_private_message_keys functions in the
7745 Added functions silc_client_send_private_message_key to send
7746 the Private Message Key payload and silc_client_private_message_key
7747 to handle incoming Private Message Key payload.
7749 * Added Cipher field to the Private Message Key payload to set
7750 the cipher to be used. If ignored, the default cipher defined
7751 in the SILC protocol (aes-256-cbc) is used.
7753 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7755 * Removed lib/silcclient/ops.h file.
7757 Redefined parts of the SILC Client Library API. Created new
7758 file silcapi.h that deprecates the ops.h file and defines the
7759 published Client Library API. Defined also private message key
7760 API and channel private key API into the file.
7762 This is the file that the application must include from the
7763 SILC Client Library. Other files need not be included by
7764 the application anymore.
7766 * Added new key_agreement client operation callback and also
7767 defined the Key Agreement library API for the application.
7769 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7771 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7772 is used by clients to request key negotiation between another
7773 client in the SILC network. If the negotiation is started it
7774 is performed using the SKE protocol. The result of the
7775 negotiation, the secret key material, can be used for example
7776 as private message key.
7778 Implemented the Key Agreement payload into the files
7779 lib/silccore/silauth.[ch].
7781 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7783 * Redefined ciphers for the SILC protocol. Added some new ciphers
7784 and defined the key lengths for the algorithms. Changed the
7785 code accordingly. The default key length is now 256 bits.
7787 * Fixed SKE key distribution function silc_ske_process_key_material
7788 when the key length is more than 128 bits. The default key
7789 length in SILC is now 256 bits.
7791 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7792 to indicate unsupported algorithm.
7794 * Renamed rijndael.c to aes.c and all functions as well.
7796 * Fixed a long standing channel key setting bug in client library.
7797 Weird that it has never surfaced before.
7799 * Fixed bug in channel deletion. If the entire channel is removed
7800 then it must also delete the references of the channel entry
7801 from the client's channel list as the client's channel entry and
7802 the channel's client entry share same memory.
7804 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7806 * Implemented CONNECT and SHUTDOWN commands in the client.
7808 * Implemented CLOSE command to the client.
7810 * Added the function silc_idlist_find_server_by_name into the
7811 files silcd/idlist.[ch].
7813 Added the function silc_idlist_find_server_by_conn into the
7814 files silcd/idlist.[ch].
7816 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7818 * DIE command was renamed to SHUTDOWN. Updated the both code
7821 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7822 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7824 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7827 * Added function silc_server_create_connection function to create
7828 connection to remote router. My server implementation actually
7829 does not allow router to connect to normal server (it expects
7830 that normal server always initiates the connection to the router)
7831 so the CONNECT command is only good for connecting to another
7834 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7836 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7837 or some other client was kicked from the channel.
7839 Implemented the handling of the notify type to both client
7842 Implemented silc_server_send_notify_kicked to send the KICKED
7843 notify. It is used to send it to the server's primary router.
7845 * Implemented the KICK command into server and client.
7847 * Added `query' argument to the silc_idlist_get_client function
7848 to indicate whether to query the client from server or not if
7851 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7852 to indicate that the client is not channel founder.
7856 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7858 * Removed the rng context from SilcPacketContext structure and
7859 changed that the packet routine uses the Global RNG API.
7861 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7863 * Added support for quit message that client can "leave" on the
7864 channel when it quits the SILC. It is ditributed inside the
7865 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7867 Added silc_server_free_client_data that will take the
7868 signoff message as argument.
7870 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7872 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7874 * Updated parts of the protocol specification to keep it up
7877 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7879 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7880 payloads in one packet.
7882 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7883 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7884 use now the new List flag.
7886 * Also deprecated the following packet types: REPLACE_ID,
7887 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7889 * Added list support for Notify packet in server.
7891 * Added silc_server_send_notify_channel_change to send the
7892 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7893 the silc_server_send_replace_id.
7895 * Added silc_server_send_notify_nick_change to send the
7896 NICK_CHANGE notify type. Deprecates the function
7897 silc_server_send_replace_id.
7899 * Added silc_server_send_notify_join to send the JOIN notify type.
7900 Deprecates the function silc_server_send_new_channel_user.
7902 * Added silc_server_send_notify_leave to send LEAVE notify type.
7903 Deprecates the function silc_server_send_remove_channel_user.
7905 * Added silc_server_send_notify_cmode and
7906 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7907 types. Deprecates the silc_server_send_set_mode function.
7909 * Added SERVER_SIGNOFF notify type to indicate that server has
7910 quit. This means that all clients on the channel from that
7911 server will drop. This can be also used when netsplit happens.
7913 Deprecated REMOVE_ID packet type since it is not needed anymore
7916 Added silc_server_send_notify_server_signoff to send the
7917 SERVER_SIGNOFF notify type. Deprecates the function
7918 silc_server_send_remove_id.
7920 Added also silc_server_send_notify_signoff to send the
7921 SIGNOFF notify type.
7923 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7924 SILC protocol from this day on. Changed the protocol
7925 specification as well.
7927 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7928 notify type. It is used between routers to notify about
7929 topic changes on a channel.
7931 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7934 * Partly updated the protocol specification to comply with the
7935 changes now made. It is still though a bit outdated.
7937 * The JOIN notify type now takes one extra argument <Channel ID>.
7938 The packet used to be destined to the channel but now the
7939 JOIN type may be sent as list thus it is impossible to
7940 destine it to any specific channel. By adding this argument
7941 it is again possible.
7943 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7945 * Added CREDITS file. The CHANGES and CREDITS file will appear
7946 in the distribution as well.
7948 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7950 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7951 types in the server's silcd/packet_receive.c.
7953 * Implemented CMODE and CUMODE to work in router environment.
7955 * Fixed minor encoding and decoding buglet from the
7956 lib/silccore/silcmode.c.
7958 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7961 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7963 * Changed all SilcConfigServer* and silc_config_server* to
7964 SilcServerConfig* and silc_server_config*, respectively.
7967 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7969 * Associated the ID (client or server ID) to the Authentication
7970 Payload to avoid any possibility of forging. Updated the
7971 protocol specification and the code accordingly.
7973 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7975 * The RSA key length is now save to the RsaKey context in the
7976 key generation process in lib/silccrypt/rsa.c. The key length
7977 is now used to figure out the maximum size of the block allowed
7978 to be encrypted/signed.
7980 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7981 is equivalent to the silc_mp_mp2bin but does not allocate any
7984 * Changed silc_mp_mp2bin API to take length argument. If it is
7985 non-zero then the buffer is allocated that large. If zero, then
7986 the size is approximated using silc_mp_sizeinbase, which however
7989 * Created Global RNG API which is global RNG that application can
7990 initialize. After initializing, any routine anywhere in the
7991 code (including library) can use RNG without allocating a new
7992 RNG object. This was done to allow this sort of use of the
7993 RNG in code that has no chance to allocate RNG object. All
7994 applications currently allocate this and many routines in the
7995 library use this. Affected file lib/silccrypt/silcrng.[ch].
7997 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7998 it to use the Global RNG API.
8000 * Defined Authentication Payload into protocol specification that
8001 is used during SILC session to authenticate entities. It is
8002 used for example by client to authenticate itself to the server
8003 to obtain server operator privileges.
8005 Implemented this payload into the lib/silccore/silcauth.[ch].
8006 Implemented also routines for public key based authentication
8007 as the new protocol specification dictates.
8009 Moved definitions of different authentication methods from
8010 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
8012 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
8013 silc_pkcs_verify and silc_pkcs_sign_with_hash and
8014 silc_pkcs_verify_with_hash functions into the file
8015 lib/silccrypt/silcpkcs.[ch].
8017 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8019 * The client entry's userinfo pointer must be always valid.
8020 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
8021 will fail since it requires the userinfo. Now, the userinfo
8022 is allocated as "" if actual userinfo does not exist. Actually,
8023 it must exist and it is totally Ok to drop client connections
8024 that does not announce the userinfo. However, we will make
8025 this workaround for now.
8027 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
8028 to return the remote port by socket.
8030 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8032 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
8033 SILC_SERVER_PENDING_EXEC and added an new macro
8034 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
8035 data or when error occurs while processing the pending command.
8037 Added new argument `destructor' into silc_server_command_pending
8038 and to the SilcServerCommandPending object. This destructor is
8039 now called after calling the pending callback or if error occurs
8040 immediately. If error occurs the actual pending callback won't
8041 be called at all - only the destructor. The destructor may be
8042 NULL if destructor is not needed.
8044 All this applies for client library code as well. Similar
8045 changes were made there as well for the pending commands.
8047 In the client, the application must now allocate the
8048 SilcClientCommandContext with the silc_client_command_alloc
8051 * Added reference counter to the SilcServerCommandContext. Added
8052 function silc_server_command_alloc and silc_server_command_dup
8055 Same type of functions added to the client library for the same
8058 * Removed the cmd_ident from IDListData away since it is now
8059 global for all connections. It is the command identifier used
8060 in command sending and with pending commands. The affected file
8063 * Added reference counter to the SilcSocketConnection objecet to
8064 indicate the usage count of the object. The object won't be
8065 freed untill the reference counter hits zero. Currently only
8066 server uses this, and client ignores it. The client must be
8067 set to use this too later. The affected files are
8068 lib/silccore/silcsockconn.[ch]. Added also the function
8069 silc_socket_dup to increase the reference counter.
8071 This was mainly added because it is possible that the socket
8072 is removed underneath of pending command or other async
8073 operation. Now it won't be free'd and proper DISCONNECTING
8074 flags, etc. can be set to avoid sending data to connection that
8075 is not valid anymore.
8077 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
8078 the connection. After that it sets SILC_SET_DISCONNECTED.
8079 It is, however, possible that the socket data is not still freed.
8080 The silc_server_packet_process now checks that data is not
8081 read or written to connection that is DISCONNECTED. The socket
8082 get's freed when the reference counter hits zero.
8084 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8086 * Changed the client operation API: channel_message operation's
8087 `sender' is now the client entry of the sender, not the nickname
8088 and the `channel' is the channel entry, not the channel name.
8090 In the private_message operation the `sender' is now also the
8091 client entry of the sender not the nickname.
8093 Affected file is lib/silcclient/ops.h and all applications
8094 using the client operations.
8096 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8098 * Moved the calling of ops->connect() from connect_to_server_final
8099 into receive_new_id functin since that is the point when the
8100 client is actually allowed to send traffic to network. The
8101 affected file is lib/silcclient/client.c.
8103 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8105 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
8106 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
8107 (if needs broadcasting) instead of broadcasting the packets one
8108 by one which would make a burst in the network traffic.
8110 * Added `broadcast' argument to the functions in silcd/server.[ch]
8111 silc_server_create_new_channel[_with_id] to indicate whether
8112 to send New Channel packet to primary router.
8114 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8116 * Added new function into the silcd/server.[ch] files:
8117 silc_server_create_new_channel_with_id to create new channel with
8118 already existing Channel ID.
8120 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
8121 lib/silccore/silcpacket.h. This packet is used t send list of
8122 Set Mode payloads inside one packet. Server uses this to set
8123 the modes for the channels and clients on those channels, that it
8124 announced to the router when it connected to it. The protocol
8125 specification has been updated accordingly.
8127 * The silc_server_new_channel did not handle the packet coming
8128 from normal server as it normally does not send that. However,
8129 when it announces its channels it does send it. Implemented
8130 the support for that.
8132 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
8133 into the file lib/silccore/id.h.
8135 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8137 * Fixed memory leaks in the functions silc_idlist_del_client,
8138 silc_idlist_del_channel and silc_idlist_del_server in the file
8139 silcd/idlist.c. All of those leaked like a sieve.
8141 * Fixed some small memory leaks in the client's function
8142 silc_client_notify_by_server.
8144 * Added functions into silcd/server.c: silc_server_announce_clients,
8145 silc_server_announce_channels and silc_server_announce_server.
8146 These functions are used by normal and router server to announce
8147 to its primary router about clients, channels and servers (when
8148 router) that we own. This is done after we've connected to the
8151 These functions effectively implements the following packet types:
8152 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
8153 and SILC_PACKET_NEW_ID_LIST.
8155 * Added new functions into the silcd/packet_receive.[ch]:
8156 silc_server_new_id_list, silc_server_new_channel_list and
8157 silc_server_new_channel_user_list to handle the incoming
8158 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
8160 * Added support of changing Channel ID in the function
8161 silc_server_replace_id. If the server that announces a channel
8162 to the router already exists in the router (with same name but
8163 with different Channel ID), router is responsible to send
8164 Replace ID packet to the server and force the server to change
8165 the Channel ID to the one router has.
8167 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
8168 client that the Channel ID has been changed by the router. The
8169 normal server sends this to the client. Client must start using
8170 the new Channel ID as the channel's ID.
8172 Implemented handling of this new type into lib/silcclient/client.c
8173 into the function silc_client_notify_by_server.
8175 * Added new function silc_idlist_replace_channel_id into the files
8176 silcd/idlist.[ch] to replace the Channel ID.
8178 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8180 * Call silc_server_command_identify_check always when processing
8181 the IDENTIFY command in silcd/command.c
8183 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8185 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
8186 send keepalive packets. The packet can be sent by clients,
8187 servers and routers.
8189 Added function silc_socket_set_heartbeat into the file
8190 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
8191 If not set, the heartbeat is not performed. The actual
8192 heartbeat is implemented in the low level socket connection
8193 library. However, application is responsible of actually
8196 Added silc_server_send_heartbeat to send the actual heartbeat
8197 packet into silcd/packet_send.[ch]. Server now performs
8198 keepalive with all connections.
8200 * Added silc_task_get_first function into lib/silcutil/silctask.c
8201 to return the timeout task with shortest timeout. There was a bug
8202 in task unregistration that caused problems. TODO has been
8203 updated to include that task system must be rewritten.
8205 * The client library will now resolve the client information when
8206 receiving JOIN notify from server for client that we know but
8207 have incomplete information.
8209 * Rewrote parts of silc_server_remove_from_channels and
8210 silc_server_remove_from_one_channel as they did not remove the
8211 channel in some circumstances even though they should've.
8213 * Encryption problem encountered in server:
8215 The LEAVE command used to send the Channel Key packet to the
8216 router immediately after generating it. However, the code
8217 had earlier sent Remove Channel user packet but not immediately,
8218 ie. it was put to queue. The order of packets in the router
8219 was that Channel Key packet was first and Remove Channel User
8220 packet was second, even though they were encrypted in the
8221 reverse order. For this reason, MAC check failed. Now, this
8222 is fixed by not sending the Channel Key packet immediately but
8223 putting it to queue. However, this is more fundamental problem:
8224 packets that are in queue should actually not be encrypted
8225 because packets that are sent immediately gets encrypted
8226 actually with wrong IV (and thus MAC check fails). So, packets
8227 that are in queue should be encrypted when they are sent to
8228 the wire and not when they put to the queue.
8230 However, the problem is that the current system has not been
8231 designed to work that way. Instead, the packet is encrypted
8232 as soon as possible and left to the queue. The queue is then
8233 just purged into wire. There won't be any fixes for this
8234 any time soon. So, the current semantic for packet sending
8237 o If you send packet to remote host and do not force the send
8238 (the packet will be in queue) then all subsequent packets to the
8239 same remote host must also be put to the queue. Only after the
8240 queue has been purged is it safe again to force the packet
8243 o If you send all packets immediately then it safe to send
8244 any of subsequent packets through the queue, however, after
8245 the first packet is put to queue then any subsequent packets
8246 must also be put to the queue.
8248 Follow these rules and everything works fine.
8250 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8252 * Added new function silc_server_remove_clients_by_server to
8253 remove all client entries from ID list when the server connection
8254 is lost. In this case it is also important to invalidate all
8255 client entires as they hold the invalid server entry. This
8256 fixes fatal bug when server has lost connection and will reconnect
8259 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8261 * Made some sanity checks to silc_server_daemonise like to check
8262 whether the requested user and group actually exists.
8264 * Added sanity check to SKE's silc_ske_responder_finish to check
8265 that the public and private key actually is valid.
8267 * Invalidate the client's nickname when receiving Replace ID
8268 packet and the Client ID is being replaced. This means that the
8269 server will query the nickname if someone needs it (client)
8272 * Sort the ID Cache in client library when the ID Cache data
8273 has changed (needs sorting).
8275 * Do not allow for SILC client to create several connections to
8276 several servers. The client does not support windows right now
8277 and generating multiple connections causes weird behaviour.
8279 Irssi-silc client does support windows and can handle several
8280 connections without problems, see: www.irssi.org and SILC plugin.
8282 * Fixed some places where client was added to the IDList. The
8283 rule of thumb is following (in order to get everything right):
8284 If the client is directly connected local client then the
8285 `connection' argument must be set and `router' argument must be
8286 NULL to silc_idlist_add_client function. If the client is not
8287 directly connected client then the `router' argument must
8288 bet set and the `connection' argument must be NULL to the
8289 silc_idlist_add_client function.
8291 * The funtion silc_server_packet_send_local_channel actually did
8292 not check whether the client was locally connected or not. It
8293 does that now. Fixed a bug related to LEAVE command.
8295 * Fixed Remove Channel User payload parsing bug in server's
8296 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
8298 * The server's silc_server_save_channel_key now checks also the
8299 global ID list for the channel as it might not be in the local
8300 list. Fixed a bug related to LEAVE command.
8302 * Is this the end of the [<unknown>] buglet that has been lurking
8303 around for a long time? A little for loop fix in server's
8304 silc_server_command_whois_parse that is used by both IDENTIFY
8305 and WHOIS command. At least, this was a clear bug and a cause
8306 of one type of [<unknown>] buglet.
8308 * WHOIS and IDENTIFY commands call the function
8309 silc_server_command_[whois/identify]_check function even if
8310 we are not router server.
8312 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8314 * Added --with-gmp configuration option. If set the GMP
8315 is always compiled in the SILC source tree. If not set then
8316 it is checked whether the system has the GMP3 installed. If
8317 it has then the GMP won't be compiled (the system's headers
8318 and library is used), if it doesn't have it then the GMP is
8319 compiled in the SILC source tree.
8321 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8323 * Changed RSA private exponent generation to what PKCS #1
8324 suggests. We try to find the smallest possible d by doing
8325 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
8326 not security fix but optimization.
8328 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8330 * Added new config entry [Identity] to fork the server and run
8331 it as specific user and group. A patch from Bostik.
8333 * Imported Dotconf configuration library into lib/dotconf.
8334 This will be used to create the SILC configuration files later.
8335 It will appear in the distsribution after this commit.
8337 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8339 * A big code auditing weekend happening. Auditing code for
8340 obvious mistakes, bugs and errors. Also, removing any code
8343 Removed files for being obsolete:
8345 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
8346 inline in the file lib/silcutil/silcbuffer.h)
8348 o lib/silcutil/silcbufutil.c (the header has inline versions)
8350 Changed code to fix possible error conditions:
8352 o The buffer formatting routines now check that the destination
8353 buffer really has enough space to add the data. This applies for
8354 both buffer formatting and unformatting
8355 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
8356 unformatting was changed to accomodate following rules:
8357 XXX_*STRING_ALLOC will allocate space for the data into the pointer
8358 sent to the function while XXX_*STRING will not allocate or copy
8359 the data into the buffer. Instead it sets the pointer from the
8360 buffer into the pointer sent as argument (XXX_*STRING used to
8361 require that the pointer must be allocated already). This change
8362 makes this whole thing a bit more consistent and more optimized
8363 (note that the data returned in the unformatting with XXX_*STRING
8364 must not be freed now). The routines return now -1 on error.
8366 o Tried to find all code that use buffer_format and buffer_unformat
8367 and added return value checking to prevent formatting and
8368 especially unformatting errors and possible subsequent fatal
8371 o Changed ske->x and ske->KEY to mallocated pointers in
8372 lib/silcske/silcske.h. Fixed possible data and memory leak.
8374 o Added return value checking to all *_parse* functions. Fixed
8375 many memory leaks as well.
8377 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
8378 so that buffer overflows would not happen. All code now also
8379 checks the return value as it can fail.
8381 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8383 * Added reconnection support to server if the normal server looses
8384 its connection to the router (for example if router is rebooted).
8385 The server performs normal reconnection strategy implemented
8386 to the server. Affected file silcd/server.c.
8388 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8390 * Added new packet type SILC_PACKET_SET_MODE that is used to
8391 distribute the information about changed modes (for clients,
8392 channels and clients channel modes) to all routers in the
8393 network. Updated the protocol specification accordingly.
8395 Added functions into silcd/packet_send.c and
8396 silcd/packet_receive.c: silc_server_send_set_mode,
8397 silc_server_set_mode.
8399 Added new files silcmode.[ch] into lib/silccore that implements
8400 the encoding and decoding of Set Mode Payload. Added new type
8401 SilcSetModePayload. Moved the definitions of different modes
8402 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
8404 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8406 * Oops, a little mistake in server's connection authentication
8407 protocol. The protocol is not ended with FAILURE but with
8408 SUCCESS if the authentication is Ok. :) Affected file is
8411 * Implemented NICK_CHANGE notify handling in server in the file
8412 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
8413 the local clients on the channel. After the changing nickname
8414 in router environment snhould work and the [<unknown>] nickname
8415 should appear no more.
8417 The silc_server_replace_id function that receives the Replace ID
8418 payload now sends the NICK_CHANGE notify type also in the file
8419 silcd/packet_receive.c
8421 * Changed WHOIS and IDENTIFY command to support the maximum amount
8422 of arguments defined in protocol specs (3328 arguments). This
8423 fixed a bug that caused problems when there were more than three
8426 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8428 * Added extra parameter, command identifier, to the
8429 silc_client_send_command so that explicit command identifier
8432 Changed that ID list routines uses specific command identifier
8433 when sending WHOIS/IDENTIFY requests to the server so that they
8434 can be identified when the reply comes back.
8436 Affected files lib/silcclient/command.[ch],
8437 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
8439 * Added `sender' argument to silc_server_packet_send_to_channel
8440 to indicaet the sender who originally sent the packet to us
8441 that we are now re-sending. Ignored if NULL. Affected file
8442 silcd/packet_send.[ch].
8444 * Added some server statistics support in silcd/server_internal.h
8445 SilcServerStatistics structure and around the server code. Also
8446 send some nice statistics information when client is connecting
8449 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8451 * Fixed channel ID decoding in server's JOIN command reply in
8452 silcd/command_reply.c
8454 * Fixed braodcasting of replace ID payload to not to send it if
8455 we are standalone server in silcd/packet_receive.c.
8457 * Fixed all channel message sending routines to not to send
8458 packets to clients that has router set, since they are routed
8459 separately in the same function earlier. Affects file
8460 silcd/packet_send.c and all channel packet sending functions.
8462 * In USERS reply, res_argv[i] are not allocated, the table
8463 is allocated. Thus changed that free the table, not its
8466 * In server's whois_check and identify_check if the client is
8467 locally connected do not send any WHOIS commands - they are not
8470 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8472 * Fixed some minor bugs in client when sending WHOIS command. The
8473 arguments was in wrong order.
8475 * Removed statis function add_to_channel from server in
8476 silcd/command.c that was previously used with the joining but
8479 * Tested USERS command in router environment successfully with two
8480 routers, two servers and two clients.
8482 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8484 * Reorganized the USERS command and command reply in client library
8485 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
8486 When the command is given by user we register a pending command
8487 callback that will reprocess the command after the reply has been
8488 received from the server. When reprocessing the packet we then
8489 display the information. Thus, the USERS information is displayed
8490 now in the command callback instead of in the command reply
8491 callback. The processing of the command is same as previously
8492 when server has sent the command reply in the JOINing process.
8494 * Added to USERS command in silcd/command_reply.c to join the client,
8495 we didn't use to know about, to the channel after we've created
8496 a client entry for it. Also, for clienet we did know already still
8497 check whether it is on the channel or not and add it if not.
8499 * Removed silc_server_command_join_notify as the function and its
8502 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8504 * Changed the client's pending command handling to the same as the
8505 server's pending command handling. It is also now possible to
8506 execute command reply functions from other command reply
8507 function as the function callbacks for commands and command
8508 replies are one and same. The pending commands are not static
8509 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8510 in client connection context. Thus, pending commands are server
8511 connection specific as it is convenient.
8513 Changed the function silc_client_command_pending and
8514 silc_client_command_pending_del and added new function
8515 silc_client_command_pending_check. Removed the
8516 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8519 * Added cmd_ident, current command identifier, to the client
8520 connection context in lib/silcclient/client.h to keep track on
8521 command identifiers used in command sending. Client's command reply
8522 function handling now supports the mandatory command identifiers.
8524 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8525 funtions in client to fully support pending command callbacks.
8527 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8528 as one of the arguments to the application in the command reply
8531 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8532 before first releasing SILC but came back. Now it is removed again
8533 and should come back nomore. The FORWARDED flag was used only
8534 by the JOINing procedure by forwarding the command packet to router.
8535 Now, the JOINing procedure has been changed to more generic (due
8536 to various router environment issues) and FORWARDED is not needed
8537 anymore for anything. The protocol specification is yet to be
8540 Now, removed silc_server_packet_forward from server and the flag
8541 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8543 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8545 * Renamed NAMES command to USERS command. The NAMES was named that
8546 due to historical reasons. Now it is renamed. Also, rewrote
8547 parts of the USERS command. The nickname list is not sent anymore
8548 by the server. Only Client ID and mode lists are sent in the USERS
8549 command. Changed this also to the protocol specification.
8551 The client now resolves the names and stuff after it receives
8552 the USERS list from the server when joining to the channel.
8554 * WHOIS and IDENTIFY commands has been changed to support multiple
8555 Client ID's per command. One can now search for multiple users
8556 in the network by sending only one WHOIS or IDENTIFY command.
8557 Changed the code and the protocol specifications.
8559 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8560 uses silc_server_command_whois_parse to parse the request. */
8562 * If normal server, do not parse the WHOIS and IDENTIFY requests
8563 before sending it to the router. Saves some time.
8565 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8567 * Fixed JOIN command on client library. Wrong number of arguments
8568 used to crash the client.
8570 * Added silc_server_channel_has_global function to check whether
8571 channel has global users or not.
8573 * Added silc_server_channel_has_local function to check whether channel
8574 has locally connected clients on the channel.
8576 * The silc_server_remove_from_one_channel now checks whether the
8577 channel has global users or not after given client was removed from
8578 the channel. It also checks whether the channel has local clients
8579 on the channel anymore. If it does not have then the channel entry
8580 is removed as it is not needed anymore.
8582 * The silc_server_notify now checks on JOIN notify whether the joining
8583 client is one of locally connected or global. If it is global then
8584 the channel has now global users on the channel and that is marked
8585 to the channel entry. Also, it now saves the global client to
8586 global list who is joining and JOINs it to the channel. This is
8587 for normal server, that is.
8589 Changed silc_server_send_notify_on_channel,
8590 silc_server_packet_relay_to_channel and
8591 silc_server_packet_send_to_channel check if we are normal server
8592 and client has router set (ie. global client) do not send the
8593 message to that client, as it is already routed to our router.
8595 * Implemented LEAVE notify type handling in silc_server_notify
8598 * Tested LEAVE command in router environment successfully. Tested
8599 with two routers, two servers and two clients.
8603 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8605 * Implemented SIGNOFF notify type handling in silc_server_notify
8608 * silc_server_remove_id now removes the client entry from all channels
8609 it has joined and thusly sends SIGNOFF notify type.
8611 * Rewrote the NAMES list generation in server by removing two excess
8612 loops. The lists are created now inside one loop.
8614 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8616 * silc_server_remove_channel_user checks now also global list
8617 for channel and client.
8619 * silc_server_new_channel_user checks now both local and global
8620 list for channel and client. Fixed a bug in client id decoding.
8621 Used to decode wrong buffer.
8623 * silc_server_channel_message checks now both local and global
8624 list for channel entry.
8626 * Tested channel joining (hence JOIN) in router environment
8627 successfully. Tested with two routers, two servers and two
8630 * Tested channel message sending in router environment successfully.
8632 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8634 * Added silc_server_save_channel_key into server.[ch] to save the
8635 received channel key in Channel Key payload processing. It is
8636 also used in JOIN command reply handling.
8638 Equivalent function silc_client_save_channel_key added into
8639 client.[ch] into client library.
8641 * Changed JOIN command reply to send information whether the channel
8642 was created or not (is existing already) and the channel key
8643 payload. Changed protocol specs accordingly.
8645 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8646 the request was sent by ID and not by nickname. Crashed on
8649 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8651 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8652 now correctly save the received data.
8654 * silc_server_free_sock_user_data now notifies routers in the
8655 network about entities leaving the network.
8657 At the same time implemented functions silc_server_remove_id
8658 and silc_server_send_remove_id to receive and send REMOVE_ID
8659 packets. The packet is used to notify routers in the network
8660 about leaving entities. The ID removed will become invalid in
8663 * Added function silc_idlist_del_server into server. Removes and
8664 free's server entry from ID list.
8666 * silc_server_private_message function now checks, if we are router,
8667 that the destination ID really is valid ID, naturally.
8669 * In router when NEW_ID packet is received (for new client) the
8670 hash of the Client ID is saved in the ID Cache but the
8671 client->nickname is set to NULL, instead of putting the hash
8674 IDENTIFY command now also checks that client->nickname must be
8675 valid. If it is not if will request the data from the server who
8676 owns the client. Added new function
8677 silc_server_command_identify_check.
8679 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8680 to set the command to already allocated Command Payload.
8682 * Tested private message sending in router environment with two
8683 routers, two servers and two clients. Fixed minor bugs and now
8686 * Fixed segfault from client's NAMES command. Used to crash if
8689 * Forwarded packets must not be routed even if it is not destined
8690 to the receiver. Changed server code comply with this.
8692 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8694 * Added `require_reverse_mapping' boolean value to ServerParams
8695 structure. If TRUE (not default) the server will require that
8696 the connecting host has fully qualified domain name.
8698 If the reverse mapping is not required and hostname could not be
8699 found the IP address is used as hostname.
8701 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8703 * Implemented version string checking to both client and server.
8704 The check is incomplete currently due to the abnormal version
8705 strings used in development version of SILC.
8707 * Changed all command functions in server to use the new
8710 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8712 * Changed char *data to unsigned char *data in ID Cache system to
8713 support binary data as ID Cache data. Changed code to support
8714 binary data in lib/silccore/idcache.c.
8716 * Renamed silc_server_packet_relay_command_reply to
8717 silc_server_command_reply as it is normal packet receiving
8718 function. Rewrote the function to accept command replys for
8719 servers and not only for clients.
8721 * Mark remote router always as registered server if we are connecting
8722 to it. Otherwise, commands sent by the router to us are ignored.
8724 * All ID List find routines now returns the ID Cache Entry pointer
8725 as well if requested.
8727 * WHOIS command works now in router environment, tested with two
8728 routers, two servers and two clients.
8730 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8731 in router environment (as it is almost equivalent to WHOIS) but
8732 hasn't been tested thoroughly. Added new functions:
8734 silc_server_command_identify_parse
8735 silc_server_command_identify_send_reply
8736 silc_server_command_identify_from_client
8737 silc_server_command_identify_from_server
8739 * Disabled route cache adding because adding two different ID's with
8740 same IP replaces the old cache entry thus giving wrong route.
8741 The entry->router->connection is always the fastest route anyway
8742 so route cache may not be needed. Of course, new routes maybe
8743 established after receiving the ID when the entry->router->connection
8744 might not be anymore the most optimal.
8746 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8748 * Add route cache for received ID for fast routing.
8750 * Added silc_server_packet_route to route received packet on router
8751 that is not destined to us.
8753 * Renamed silc_server_get_route to silc_server_route_get.
8755 * Added id_string and id_string_len fields into SilcServer to
8756 include encoded ServerID for fast comparing without excess
8757 encoding of the ID's.
8759 * Cleaned up WHOIS command on server side. Added following static
8762 silc_server_command_whois_parse
8763 silc_server_command_whois_check
8764 silc_server_command_whois_send_reply
8765 silc_server_command_whois_from_client
8766 silc_server_command_whois_from_server
8768 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8769 arguments in command replies. All command functions should be
8770 updated to use this macro.
8772 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8774 * Minor typo fixes on command reply handling on server.
8776 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8778 * Added silc_server_command_add_to_channel internal routine to add
8779 the client to the channel after router has created the channel and
8780 sent command reply to the server.
8782 * Added generic silc_server_send_command to send any command from
8785 * Use static buffer with ID rendering instead of duplicating data.
8787 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8789 * Fixed a channel user mode bug when joining to a channel server gave
8790 everybody channel founder rights, oops.
8792 * We mark ourselves as the router of the incoming server connection
8793 if we are router ourselves. This way we can check in some packet
8794 sending functions whether it is locally connected server. For
8795 incoming router connections we put NULL.
8797 * For router sending packets locally means now always sending the
8798 packet cell wide; to local clients and local servers. For normal
8799 server sending packet locally means sending it to only local
8802 * Fixed the JOIN command to really work in router environment. If the
8803 channel is created it is always created by the router. Router is
8804 also responsible of making the initial joining to the channel,
8805 sending JOIN notify to the sending server and distributing
8806 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8807 does not exist server doesn't do anything else but forward the
8808 command to the router which performs everything.
8810 * Added silc_server_send_channel_key function to send the Channel Key
8813 * Added silc_server_create_channel_key to create new channel key. The
8814 channel key is now re-generated everytime someone joins or leaves
8815 a channel, as protocol dictates. Note: channel->key_len is the
8818 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8820 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8821 packet_receive.[ch] to separate packet sending and receiving
8822 routines. The server.[ch] now includes everything else including
8823 actual packet processing (writing and reading data) and other
8826 Renamed silc_server_private_message_send_internal to
8827 silc_server_send_private_message. The routine is still though
8828 used only to relay private messages as server does not send
8829 private messages itself.
8831 Renamed silc_server_new_channel to silc_server_create_new_channel
8832 and added new function sicl_server_new_channel that handles the
8833 incoming New Channel packet. Added also new sending function
8834 silc_server_send_new_channel to send New Channel Payload.
8836 * Added new function silc_server_notify to process incoming notify
8837 packet to the server/router. Server may then relay the notify
8838 to clients if needed.
8840 * Added new function silc_server_new_channel_user to process incoming
8841 New Channel User packet. Router will redistribute the packet and
8842 send JOIN notify to its local clients and locally connected servers
8843 if needed. Normal server will send JOIN notify to its local client
8844 on same channel when received this packet. Added also corresponding
8845 sending function silc_server_send_new_channel_user to sent the
8848 * Added boolean route argument to send_notif_to_channel and
8849 packet_send_to_channel functions to attempt to route the packet
8850 if it is TRUE and send only locally if it is FALSE.
8852 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8854 * silc_server_replace_id now broadcasts the received replace ID
8855 packet if it is not broadcast packet already. The router must
8856 broadcast to inform other routers about changed ID.
8858 * Added backpointer to server's router into SilcServer context in
8859 silcd/server_internal.h.
8861 * Fixed silc_server_packet_broadcast to send correct broadcast
8864 * The channel key is now distributed to the local client as soon
8865 as it is received from the router (in router environment) so that
8866 no other packet may be sent for the channel until client has
8869 * silc_server_remove_channel_user now broadcasts the received
8870 Remove Channel User packet if it is not broadcast packet already.
8871 The router must broadcast to inform other routers about removed
8874 * Added users field into SilcPacketContext that is a reference count
8875 of the context. One can increase the reference count by calling
8876 silc_packet_context_dup which is now changed to just increase the
8877 reference count instead of duplicating the data. The reference
8878 count is decresed by calling silc_packet_context_free that will
8879 free the data after the reference count hits zero.
8881 For now on the packet context and everything allocated into it
8882 (including the raw packet from network) must be freed by calling
8883 the new silc_packet_context_free function. Added also new function
8884 silc_packet_context_alloc that must be used now to allocate the
8885 context. This also means that if a routine is asynchronous from
8886 silc_[client/server]_packet_parse_type the packet context must
8887 be duplicated by calling silc_packet_context_dup. Otherwise it
8888 gets free'd after silc_[client/server]_packet_parse_type returns.
8889 Also, one must remember that if packet is duplicated then its
8890 reference count must be decresed by calling the free function as
8891 many times as it was duplicated.
8893 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8894 from both client and server.
8896 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8898 * Made joining to a channel working in router environment.
8900 * Cleaned up JOIN command on server side and create function
8901 silc_server_command_join_channel internal routine to make the
8904 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8906 * Changed silc_command_pending list to SilcDList. Also, added
8907 `ident' field to SilcServerCommandPending structure to identify
8908 the reply and to call correct callback.
8910 Added silc_server_command_pending_check function to replace the
8911 corresnponding macro. The silc_command_pending list is not
8914 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8915 to set identifier to previously allocated Command Payload. It
8916 is used to set identifier for command when resending Command
8919 * Added silc_command_payload_encode_payload to encode Command
8920 Payload buffer from SilcCommandPayload structure.
8922 * Added silc_argument_payload_encode_payload to encode Argument
8923 payload buffer from SilcArgumentPayload structure.
8925 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8927 * Changed WHOIS command to support router connection on server side.
8928 The whois request is always sent to router unless the server is
8929 standalone server. After server has received the reply from the
8930 router will it send the reply to the client.
8932 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8933 broadcast received broadcast packet. The function is used only
8934 by router. The broadcast packet is always sent to the router's
8937 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8938 render given ID to printable string, for log files for example.
8940 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8942 * Made basic router to router connections working. At least they
8943 can now connect to each other but nothing really works the way
8944 they are supposed - yet.
8946 * Added new initiator token to RouterConnection configuration
8947 file in silcd/serverconfig.[ch]. It is used to tell whether we
8948 are the initiator to the remote router or whether we'll expect
8949 the other end to connect.
8951 * Moved registering of listener task to silc_server_init, hence
8952 the server starts listenning as soon as it is run, even if it
8953 does not have connections to other routers. Let's see how well
8956 * Changed default connection retry timeouts for more suitable in
8959 * Removed cipher and such arguments from silc_idlist_add_client
8960 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8961 Added new function silc_idlist_add_data to add the keys and stuff
8964 * Added SilcIDListData structure and added it to SilcClientEntry
8965 and SilcServerEntry as their first field in the structure. This
8966 way we can explicitly cast the ID entries to the SilcIDListData
8967 structure and get common data for the entries. In past, we had
8968 to first check what type of connection it is and then cast it to
8969 correct ID entry type. Now, we can directly cast the opaque
8970 pointer to the SilcIDListData (no matter what ID entry it actually
8971 is) and get the data needed.
8973 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8975 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8976 in some circumstances even if threre were timeout tasks, though not
8977 IO tasks, but tasks anyway. Now fixed.
8979 * Defined SilcServerConnection structure to hold connection specific
8980 stuff about directly connected servers and routers. The definition
8981 is currently in silcd/server_internal.h. I thought about having
8982 a bit more important role fro this struct but for now it is used
8983 only when connecting to other server (or router actually).
8985 * Added connecting retry support in server when connecting to
8986 router(s). The retry feature implement exponential backoff
8987 algorithm. Also, added SilcServerParams structure to hold default
8988 parameters for server. For now, it include these retry settings
8989 and are hard coded. After server is moded to be as Silc Server
8990 Library this structure will be more important.
8992 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8994 * Changed client librarys channel->clients table to SilcList and
8995 changed code accordingly.
8997 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8999 * Changed client's channel table to SilcList and changed code
9000 accordingly. Also changed SilcChannelClientEntry to include back-
9001 pointer to the channel so that client entry can use that structure
9002 as list as well and we have fast cross-reference to the channel.
9003 This change dramatically decreased the complexity of channel
9004 handling with client entry and vice versa (removed one extra
9005 loop when searching for channel entry from many functions).
9007 * Changed server->sim from table to SilcDList and changed code
9010 * NAMES command can now be used from user interface. It will show
9011 the user list on the channel, neatly.
9013 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
9014 Code now saves realname of the user if it becomes available.
9016 * Renamed configure.in to configure.in.pre and made ./prepare
9017 script to automatically add correct version string to
9018 configure.in which it creates from configure.in.pre.
9020 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9022 * NAMES command reply now shows users mode with the nickname when
9025 * Moved silc_client_ch[u]mode[_char] functions from
9026 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
9027 place sucks, they are utility functions and should be in some
9030 * Fixed some unsigned int's to unsigned short's. Patch by cras.
9032 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
9035 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9039 * Added TRQ (efficient deque and list library) into lib/trq. This is
9040 a very good list library that is currently used in the SILC. Defined
9041 SilcList API over the library because I didn't like the API very
9042 much. See lib/trq/silclist.h for the API and examples of how to
9043 use the API. Fixed various places in the code to use the new
9044 SilcList API. The SilcList is meant for lists that has a structure
9045 already defined as a list. It is not suitable to add just some
9046 context to the list (in TRQ, the context is the list actually).
9048 So, I defined SilcDList that can be used for the purpose where
9049 predefined list structure does not exit. This can be used as
9050 such list. Now some context just can be added to the SilcDList.
9051 Currently this list is not used in the SILC just yet, though there
9052 are a lot places where this can replace dynamically allocated
9053 tables and I will fix these places, later, to use SilcDList.
9054 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
9055 and use TRQ internally).
9057 Also fixed some annoying warning messages that the original TRQ
9058 code generated. Also minor changes to TRQ's Makefile.in.
9060 * Added support for querying by Client ID to both WHOIS and
9061 IDENTIFY commands into server, as required by the protocol.
9063 * Removed method function pointers from SilcBuffer structure. They
9064 weren't used to anything and just increased the context size for
9065 no good reason. This change also made silc_buffer_alloc and
9066 silc_buffer_free functions inline functions.
9068 * Disabled command flooding detection support until it's fixed so
9069 that it accepts commands in but does not execute them more than once
9072 * Added silc_net_localhost(), to return local hostname, into
9073 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
9074 that must be initialized before calling silc_client_init.
9076 * Added new function: silc_server_send_notify_on_channels to send
9077 notify messages to all channels client has joined. It is assured
9078 that the message is sent only once per client.
9080 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
9081 lib/silcutil/silcutil.[ch] as silc_format function. The new
9082 function is generic and is used by server as well, not only by
9083 the logging routines.
9085 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
9086 the provided version string was not acceptable. Added new function:
9087 silc_ske_check_version into lib/silcske/silcske.h. The function
9088 must be implemented by the application (client or server) and it
9089 does not reside in the SKE library. The function checks the version
9090 string remote end sent.
9092 * Added back pointers (to opaque context and to SilcSocketConnection)
9093 into SilcPacketContext structure into lib/silccore/silcpacket.h.
9095 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
9096 duplicate packet context structure.
9098 * Changed `notify' client operation to send same arguments as client
9099 receives from server except for ID's. ID's are mapped to correct
9100 ID entry and that is returned. Also, if channel entry is not sent
9101 by server but the notify is for channel the channel entry is sent
9102 to application (otherwise application doesn't know that it is for
9103 channel (library gets it from packet's Destination ID)).
9105 * Added silc_client_remove_from_channels into client library to
9106 remove a client from all channels it has joined to. Used when
9107 received SIGNOFF notify from server. Added also new function
9108 silc_client_replace_from_channels to replace old ID entry with
9109 new ID entry on all channels. Used when received NICK_CHANGE
9112 * Fixed ID Cache list handling in silc_idlist_get_client in
9113 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
9114 to get (or query) client by ID.
9116 * Updated TODO list.
9118 * Added connection authentication status message defined by the
9119 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
9120 support for these into the code in client and server side.
9122 * Added generic function silc_client_send_command to send any command
9123 with variable argument list. Application should use this function
9124 to send commands if the command functions provided by the library
9125 does not suite for the application's user interface needs.
9127 * Added new `failure' client operation. Application is notified about
9128 received failure packet if client is executing a protocol. In this
9129 case the protocol's execution has failed.
9131 * Added SKE's end notify to send the SKE_SUCCESS notify message that
9132 is required by the protocol.
9134 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
9135 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
9138 * Added status flag to SilcSKE object to indicate realtime status
9139 of the SKE protocol.
9141 * Application receives now exactly same command reply arguments as
9142 the library receives from server. However, if ID is received the
9143 corresponding ID entry is returned to the application (eg. Client
9144 ID is mapped to correct SilcClientEntry entry and that is returned).
9145 Changed command_reply client operation due to this change.
9147 * Changed all ID's in commands and in command replys as ID Payloads.
9148 Change affected both client and server side codes.
9150 All ID's sent in SILC network (with execption of ID's in SILC
9151 Packet header) are sent in ID Payload to support variable length
9154 * Server now notifies nick changes and notifies all clients on
9155 the channels about the new nickname (about the new Client ID,
9158 * Implemented CMODE command to change channel modes. Supports all
9159 channel modes defined by the protocol specs except ban and invite
9160 lists. (Also, private channel key mode is supported but support for
9161 setting private channel key in client is missing, thus, this mode
9162 has no effect on client side (except that server requires that the
9163 client uses private channel key and normal channel traffic does not
9166 Also, invite mode works per se, but INVITE command does not work
9167 yet correctly, so you can set channel as invite only channel but
9168 inviting clients to the channel does not work (it is yet to be
9169 thought what's the best way to do it).
9171 * Added new command SILC_COMMAND_CUMODE to change user mode on the
9172 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
9173 Implemented CUMODE command to change user's mode on the channel.
9174 Supports all modes defined by the protocol specs.
9176 * Added NAMES command reply to return users modes on the channel.
9178 * Removed unnecessary and slow ciphers from lib/silccrypt.
9180 * Set SO_KEEPALIVE option to connection sockets by default.
9182 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
9184 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
9185 redefined the Notify Payload into protocol specs.
9187 * Added silc_id_payload_parse_id to get ID directly from raw
9190 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9192 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
9193 accept searching by Client ID as well.
9195 * Added support for LEAVE and SIGNOFF notify types in client library.
9197 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
9198 to parse ID Payload from raw data.
9200 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9202 * Added flags parameter into silc_ske_assemble_security_properties
9203 function in lib/silcske/silcske.[ch].
9205 * Changed notify client operation to fit better for notify messages
9206 sent by server. The notify payload received from server is now
9207 passed to the application (after parsing it to SilcNotifyPayload).
9208 It is application's responsibility to retrieve the arguments
9209 from the payload and show the message the way it wants. The message
9210 sent by server is implementation specific.
9212 * Changed public keys to comply with the protocol specification.
9213 Old public keys are not supported anymore and are not compatible.
9215 * Removed nickname from Channel Payload as the latest draft removed
9216 it. The client must resolve the nickname from the NAMES command
9217 reply received when it joined the channel.
9219 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
9221 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9223 * Fixed some errors in protocol specification drafts.
9225 * Created lib/silccore/silcnotify.c to implement Notify Payload
9226 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
9227 generic payloads described by protocol specifications. The file
9228 includes implementations for ID Payload and Argument Payload.
9230 * Changed Command Payload implementation to use the new Argument
9231 Payload. Changed command_xxxx_payload to command_payload_xxxx
9232 to comply with SILC coding conventions.
9234 * Added suppport for Argument Payload handling in Notify Payload
9235 implementation as protocol requires it. Added the new support
9236 into server and client lib as well.
9238 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9240 * Added support for multiple nicknames on same channel. [n] is
9241 added locally to the nickname if there are more than one same
9242 nicknames on the channel.
9244 * Server now sends all nicknames that matched WHOIS request.
9245 Client also shows the list received from server.
9247 * Added TOPIC command to client side. User can now set and show
9248 current topic on channel.
9250 * Added MOTD command to client and server. Also, server sends the
9251 motd when client connects to the server.
9253 * Changed version strings to comply ISO 8601.
9255 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9257 * Fixed protocol error handling in client library. It should now
9258 cope even if the SKE fails for some reason.
9260 * Made new protocol specification drafts for submitting to IETF.
9262 * Implemented TOPIC command to server in silcd/command.c.
9264 * Added two new notify types into lib/silccore/silcnotify.h:
9265 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
9266 notify nickname change and topic setting/change on a channel.
9268 * API change of command_reply operation in client library. The
9269 application gets now the status type received from server as well.
9271 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9273 * Removed the function just added to lib/silcutil/silcschedule.[ch].
9275 * Cras fixed and optimized the packet handling even further and
9276 it should work now. Minor change to the prototype of function
9277 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
9279 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9281 * Added new function into lib/silcutil/silcschedule.[ch]:
9282 silc_schedule_with_fd to select() a specified fd. The function
9283 returns after timeout expires or data arrives or goes. The
9284 function is used by packet routines to wait that all data is
9285 received from network.
9287 * Fixed data reading from network in lib/silccore/silcpacket.c.
9288 The code now assures that all data is read from the fd and then
9289 continues packet processing. This was a bug fix since the code
9290 used to drop some data in some circumstances.
9292 * Added new function into lib/silcclient/client.[ch]:
9293 silc_client_start_key_exchange to start key exchange after
9294 connection has been established to server. The code internally
9295 now uses this funtion but its main purpose was to provide it
9296 for applications that perform their own connecting. After
9297 application has created a connection it merely calls this
9298 function to start the key exchange between client and server.
9299 The library takes care of everything else after that.
9301 Updated also lib/silcclient/README to explain the usage of
9304 * Do not send to application information that connection has
9305 been established. Application gets notified it by connect
9308 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9310 * Applied cras's patch to add silc_schedule_one function. The
9311 function runs scheduler once and returns.
9313 * Fixed the scheduler after cras messed it up. The timeout
9314 handling works now as it's supposed to work.
9316 * Added into lib/silccore/ silcnotify.h to include notify
9317 message types support. Changed silc_server_send_notify*
9318 functions, in server.[ch], to support those new notify types.
9319 Added the support for the notify types into client library,
9320 as well. Added new notify client operation into ops.h in
9323 * Changed silc_server_packet_send_to_channel to send normal
9324 packets instead of just channel message packets. The function
9325 is now used to send the notify packets to channels. It is not
9326 used to send channel message packets anymore, as server never
9329 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
9330 va_arg()s as it seems to require it nowadays. I guess, if SILC
9331 is compiled with older va_arg() the new code should work anyway.
9333 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9335 * Splitted core library. Core library (lib/silccore) includes
9336 now only SILC protocol specific core (and common) components.
9337 Created new utility library (lib/silcutil) that includes more
9338 generic purpose stuff. The stuff for util library was taken
9339 from the old core library. This was minor and easy split.
9341 * Created SILC Client Library (lib/silcclient) that includes
9342 implementation of the SILC client without user interface. This
9343 was major move from silc/ directory. The code has been changed
9344 so that it is transparent towards the user interface. The
9345 silc/ directory includes now the same user interface as before
9346 and it uses the new client library. Read lib/silcclient/README.
9347 Basicly, the client library performs everything else related
9348 to SILC except user interface handling. Also, configuration
9349 files are considered to be part of user interface and library
9350 does not handle them.
9352 This change also changed a lot of structures, function naming etc.
9353 Most important change was that SilcClientWindow object was
9354 renamed to SilcClientConnection in the client library. Created
9355 also new file lib/silcclient/ops.h. Also added new files
9356 silc/local_command.[ch] and silc/client_ops.[ch].
9358 All these changes were made to make it easier for user interface
9359 designers to create what ever user interface for the SILC client
9362 It is also expected that the server will be moved to lib
9363 directory as well and SILC Server Library will be created;
9364 sometimes in the future.
9366 * Removed Local commands from lib/silccore/silccommand.h as
9367 they are application specific and new client library does not
9368 handle any of those anymore.
9370 * Several functions moved to lib/silcutil/silcutilc.[ch] from
9371 old client implementation in silc/.
9373 * Added support for callback functions in SILC_LOG_* macros.
9374 Application can now set its own callbacks that will be called
9375 instead of using the default functions that will always print
9376 the debug messages to stderr (or stdout). Also, debugging can
9377 now be disabled by setting silc_debug to FALSE and re-enabled by
9378 setting it to TRUE. Note, that logging will still work even
9379 if debugging is disabled.
9381 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
9382 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
9383 silc_log_reset_debug_callbacks.
9385 * To enable debugging in silc client one must give now -d
9386 option on command line.
9388 * Changed silc_schedule_init to automatically allocate task queues
9389 if they are not allocated before calling it.
9391 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9393 * Added GMP 3.1 into math library.
9395 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9397 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
9398 a channel in SILC network. The packet is used by servers and
9399 routers to notify other routers that user has left a channel.
9400 This little feature was missing until now. Added the feature
9401 to protocol specification as well.
9403 Added functions: silc_server_send_remove_channel_user and
9404 silc_server_remove_channel_user into server.[ch].
9406 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
9407 lib/silccore/silcpacket.h. However, they are not implemented
9410 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9412 * Fixed joining to a channel and sending channel messages
9413 between server and router. The channel message sending should
9414 now work inside a cell.
9416 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9418 * Fixed the private message sending between server and router.
9419 The private message sending should now work inside a cell.
9421 * Added silc_server_replace_id into server.[ch] to replace
9422 existing ID in the SILC network.
9424 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
9425 and silc_idlist_replace_server_id into idlist.[ch] in server.
9427 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9429 * Fixed the server to server connections. Server can again now
9430 connect to router. Router to router connections probably does
9433 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9435 * Added dynamic protocol registering support. Now protocols can
9436 registered and unregistered on the fly. Patch by cras.
9438 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9440 * Added lib/contrib directory to hold routines that some platforms
9441 don't have but are needed by SILC.
9443 * Added getopt.c, getopt1.c and getopt.h from GNU C library
9444 into lin/contrib to provide getopt() and getopt_long() for
9445 those who don't have it.
9447 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9449 * Added AWAY command to client. When away message is set and
9450 client receives a private message packet the client automatically
9451 replies to the sender with the away message.
9453 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
9454 bug seemed to be the cause of recent problems when compiling
9457 * Added version detection support to SKE protocol specification
9458 and added the new changes to the SKE implementation as well.
9459 There were other minor changes in the SKE protocol as well.
9461 Many changes in lib/silcske/silcske.[ch] and in
9462 lib/silcske/payload.[ch].
9464 * Added ^U functionality, clear input line. Patch from cras.
9466 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9468 * Mainly small bugfixes on core library. Fixed some debugging
9469 logging and buffer overflow in silclog.c.
9471 * Updated config.sub and config.guess on the distribution tree.
9473 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9475 * Added command lagging support in server. Client may execute
9476 commands now only once in two seconds.
9478 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9480 * Optimized packet reception. MAC computation and checking is now
9481 also more optimized. A lot previously duplicated code is now
9482 used as generic by both client and server.
9484 * Fixed key pair generation in clientutil.c
9486 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9488 * Added into lib/silccore/silcbufutil.[ch] new function;
9489 silc_buffer_realloc.
9491 * Moved generic packet sending/encryption functions to
9492 lib/silccore/silcpacket.[ch] from client and server. Some
9493 rewriting of the functions.
9495 * Moved all generic packet reception/decryption functions to
9496 lib/silccore/silcpacket.[ch] from client and server. The
9497 packet processing is now much cleaner in both client and server.
9498 These were major changes in both client and server.
9500 * Created many common functions in server to do packet sending.
9501 Previously code were duplicated a lot, this has been removed
9504 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9506 * Rewrote major parts of the ID cache system. Don't know
9507 whether it is better now or not but at least the API is more
9510 * Major rewrite on ID cache stuff on client because of the ID
9511 cache API changes. Added idlist.c to client.
9513 * Also major rewrite on ID cache stuff on server as well.
9514 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9515 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9516 in hand, instead they are all put into the ID cache system now.
9517 All server_idlist_* routines uses ID cache now instead of
9518 traversing its own lists (those lists does not exist anymore).
9519 SilcIDList though still exists. Also, SilcXXXEntry's are
9522 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9524 * Finally made the SKE implementation compliant to the protocol
9525 specification. All mp integers are now binary encoded as
9526 opposed being HEX encoded.
9528 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9531 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9532 functions: silc_[encode/decode]_pem. Also added function
9533 silc_encode_pem_file to PEM encode with newlines ('\n') for
9536 * SILC public keys are now encoded either PEM or binary. Same
9537 option is for private keys as well. By default private keys
9538 are binary encoded and public keys PEM encoded. Silly HEX
9539 encoding were removed.
9541 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9542 function to create fingerprints.
9544 * Fixed a bug in SHA1; does not change the original data anymore.
9546 * Partly implemented INFO command on client and server side.
9547 Fixed CLEAR command. Changes to SERVER command; show current
9548 server(s) when giving command without arguments. Added
9549 VERSION command to client.
9551 * Added check to server that unregistered connections cannot
9552 execute commands (unless it is specificly allowed).
9554 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9556 * Fixed screen refresh.
9558 * Fixed channel joining bug from client. On some circumstances
9559 client tried to join to a channel it had already joined.
9561 * Added public key verification process into client's protocol.c.
9562 The client now verifies the public key from user and saves
9563 it into ~./silc/serverkeys/ directory.
9565 Added into: clientutil.[ch]: silc_client_verify_server_key.
9567 * Changed SKE protocol's silc_ske_initiator_finish function
9568 to accept callback function that verifies the received public
9569 key. Removed old silc_ske_verify_public_key function.
9571 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9573 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9574 silc_pkcs_private_key[_data]_set.
9576 * Made the password and public authentication more cleaner in
9577 server's protocol.c.
9579 * Removed historic and obsolete protocol `channel_auth' from
9580 both client and server.
9582 * Removed wrong way of sending command status messages from
9583 server to client in server's command.c. The old way violated
9584 protocol specification.
9586 Changes to silccore/silccommand.[ch]: removed
9587 silc_command_encode_status_payload -> not needed anymore,
9588 changed silc_command_encode_payload_va to accept extra
9589 argument on variable argument list. The argument type must
9590 now be provided to the function. Also, added new function:
9591 silc_command_encode_reply_payload_va which is same as
9592 normal command_encode_payload_va except command status type
9593 is provided as extra argument.
9595 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>

9598 public and private keys for the client.
9600 Added silc_client_check_silc_dir, silc_client_create_identifier
9601 and silc_client_load_keys.
9603 * Implemented SILC protocol compliant public key. Added public
9604 and private key saving to and loading from files.
9606 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9607 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9608 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9609 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,

9617 * Added silc_server_get_route (route.[ch]) to get connection
9618 data for the fastest route for given ID.

9621 were re-defined in the SILC Protocol Specification and the
9622 implementation now complies with the specification.
9624 * Implemented PING command on client and server.

9640 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
