343 It is not able to send requested attributes in WHOIS command,
344 and also receive and process requested attributes. Added
345 silc_client_attribute_[add|del] and silc_client_attributes_get
346 functions. Added also `ignore_requested_attributes' to the
347 SilcClientParams to not use attributes in client. Affected
348 files are lib/silcclient/command.c, client_attrs.[ch],
349 silcclient.h, client_internal and client.[ch].

369 * Changed the silc_attribute_payload_encode to support list
370 of attributes (function may be called several times to add
371 a new attribute). Removed the silc_attribute_payload_encode_list
372 function. The encoding function now also automatically encodes
373 the data, so the caller does not need to do that. Affected
374 files lib/silccore/silcattrs.[ch].
376 * Added support for replying on behalf of the user to the
377 Requested Attributes in WHOIS command in the server. Affected
378 file silcd/server_query.c.

445 Mon Sep 16 12:02:54 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
447 * Added 'app_context' to silc_schedule_init. It is an
448 application specific context that is delivered to application
449 in task callback functions. Affected files are
450 lib/silcutil/silcutil.[ch].
452 * The hb_context in SilcSocketConnection is not freed
453 automatically anymore (application must free it). Freeing
454 it automatic is inconsistent. Affected files are
455 lib/silcutil/silcsockconn.[ch].
457 Sun Sep 15 22:16:19 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

479 Patch provided by Ville Räsänen <ville.rasanen@iki.fi>.
481 Wed Sep 11 09:22:00 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
483 * Assure that channel key is set before sending it. May
484 crash server otherwise. Affected file silcd/packet_send.c.
486 Tue Sep 10 09:50:08 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
488 * Assure that endless loop cannot happen with detached client
489 resolving on normal server. Added idlist status
490 SILC_IDLIST_STATUS_RESUME_RES. Affected files are
491 silcd/idlist.h and silcd/packet_receive.c.
493 Mon Sep 9 12:18:18 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
495 * Incoming file transfer request cannot use same session as
496 the sending session. This can happen when sending file to
497 yourself. Crashed the client on quit. Affected file
498 lib/silcclient/client_ftp.c. Bug #24.
500 Sun Sep 8 18:39:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
502 * Implemented the draft-riikonen-precense-attrs draft and
503 the Attribute Payload into the lib/silccore/silcattrs.[ch].
505 Sun Sep 8 13:13:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
507 * Distribute the SERVER_SIGNOFF notify also to local backup
508 routers from the primary router. The backup router may not
509 have the signing of local server directly connected and need
510 to know about the signoff. Affected file silcd/server_util.c.
512 * Use the primary router as the origin of the locally connected
513 server when it is disconnecting from the backup router since
514 that's where it really is coming from. Now the clients from
515 the disconnecting server are removed correctly and "shadow"
516 clients are not left to the backup router. Affected file
519 Sat Sep 7 22:26:50 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
521 * If normal server is standalone and found existing but disabled
522 channel, do not re-create the channel since it creates
523 duplicate same channels. Affected file silcd/server.c.
525 * Added anonymous client connections support to server. New
526 "anonymous" configuration option to ConnectionParams section
527 added. If set to true, the username and hostname information
528 of the client will be scrambled and anonymous user mode is
529 set automatically to the user. Affected files are
530 silcd/serverconfig.[ch], silcd/packet_receive.c and server.c.
532 Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
534 * In JOIN notify handling, mark that the cache entry of the
535 client cannot be expired. Can cause crashes on normal
536 server (asserts client->channels). Affected file is
537 silcd/packet_receive.c.
539 * From now on distribution versions are used as protocol versions
540 instead of by default using the Toolkit base version as protocol
541 version. Affected file prepare.
543 * Do not set the locally resolved hostname for local client
544 entry but take what server sends. This way the real hostname
545 is showed in WHOIS for yourself. Affected file is
546 lib/silcclient/idlist.c and lib/silcclient/client.c.
548 * Resolve local info with IDENTIFY when connecting to server.y
550 Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
552 * Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
553 for implied search (not needed on platforms which has native
554 pthreads library). Use --without-pthreads to disable threads.
555 Affected file is configure.in.pre
557 * Fixed --with-iconv on platforms which need to bypass (broken)
558 native iconv(). Affected file is configure.in.pre
560 Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
562 * Moved -C option parsing in Irssi SILC client at same time
563 as other options. The UI was initialized earlier and caused
564 problems on command line. Bug #16. Affected file is
565 irssi/src/silc/core/silc-core.c.
567 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
569 * Added global variable silc_log_timestamp that tells silclog
570 wether to print or not the timestamp in the logging files.
571 Affected file lib/silcutil/silclog.[ch].
573 * Added silcd configuration option Timestamp in the Logging
574 section. Affected file silcd/serverconfig.[ch],
575 doc/example_silcd.conf.in.
577 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
579 * Fixed fingerprint checking to check for entirely empty
580 fingerprint instead of two first bytes when determining
581 if it is set. Bug #18. Affected file silcd/command.c.
583 * Fixed duplicate PKCS name registering to not allow it.
584 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
586 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
588 * Conditionalize non-gcc compiler optimizations for various
589 platforms, enable those commented out. Cleanups.
590 Affected file lib/silcmath/mpi/configure.in
592 Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>
594 * silc_rng_exec_command() left zombie processes if command
595 didn't generate any output. Affected file
596 lib/silccrypt/silcrng.c
598 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
600 * Rewrote iconv checking, introduce --with-iconv for systems
601 which rely on libiconv. Check if iconv() provided by libc
602 is good enough, otherwise demand libiconv. Affected file
605 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
607 * Search for ldopen() also in libc. This enables SIM support
608 on *BSD systems. Based on patch from Alex Zepeda. Affected
609 file configure.in.pre
611 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
613 * Don't call AM_CONDITIONAL conditonally for SILC_THREADS.
614 This fixes prepare on *BSD systems. Affected file
617 Sun Aug 4 15:55:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
619 * More fixed for not having purge timeout for global clients
620 that are on channel. Affected files silcd/command_reply.c
623 * Fixed the rekey protocol to work with backup router connections.
624 Rekey packets are now allowed on disabled connections as
625 well. Affected files silcd/packet_send.c and server.c.
627 * Do not switch to be as backup router when shutting down and
628 closing the primary connection. Affected file silcd/server.c.
630 * Fixed memory leaks in backup router deleting. Added
631 silc_server_backup_free to free all data during shutdown of
632 server. Affected files silcd/server_backup.[ch].
634 Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
636 * Do not process commands if the sock->user_data is NULL.
637 Affected file silcd/command.c.
639 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
641 * Fixed buffer overflow and security problems (loosing bits
642 in CFB encryption) in SILC RNG. Problems reported by
643 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
645 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
647 * Added yet more checks that client is not expired on global
648 list if it is on channels. Affected file is
649 silcd/command_reply.c.
651 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
653 * Merged c0ffee's MIME signal patch which adds support for
654 sending also MIME messages in Irssi SILC Client, and handling
655 received MIME messages in a signal (and perhaps doing something
656 to non-textual MIME messages).
658 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
660 * Fixed pending command deletion in server and client library
661 to check the whole list instead of breaking after first found.
662 The affected files are silcd/command.[ch] and
663 lib/silcclient/command.[ch].
665 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
667 * Return NO_SUCH_CHANNEL error in USERS for channel that is
668 secret or private, otherwise it's possible to find out
669 whether a secret channel exists or not. Affected file
672 * If CMODE change fails during the mode setting, assure that
673 the old mode mask is set for the channel back. Affected
674 file silcd/command.c.
676 * Fixed passphrase saving on +a channel on normal server
677 after successful JOIN command. Affected file silcd/command.c.
679 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
681 * Remove server/router operator privileges in DETACH command,
682 since it's possible to resume to server where these
683 privileges would not be allowed for the client. Affected
684 file silcd/command.c.
686 * Do not set to wait for backup in rehash of the server.
687 Affected file silcd/server.c.
689 * Do not check listener sockets when counting how many
690 socket connections we have. Affected file is
693 * Do not announce disconnected clients that are remaining
694 in history (for WHOWAS). This is because SIGNOFF notify
695 for these has been sent earlier already. Affected file
698 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
700 * Buffer overflow with CUMODE command's mode->mode character
701 conversion. Reported by Ville Räsänen. Affected file
702 lib/silcutil/silcutil.c.
704 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
706 * Allow heartbeat packets to go disabled connections anyway.
707 Affected files silcd/server.c and silcd/packet_send.c.
709 * Do not broadcast New Channel packets with List flag set
710 in the packet to backup routers. The router must check
711 for the correctness of the packets before sending them.
712 It is possible that router will have enforce Channel ID
713 change and this would cause desync in the backup router.
714 Affected file silcd/packet_receive.c.
716 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
717 are handled in list parsing. They are not list packets
718 anymore. Affected file silcd/packet_receive.c.
720 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
722 * Stop waiting for backup router through the timeout, not
723 directly after backup router has arrived. Affected file
726 * Do not re-create channel keys and send them when removing
727 clients in server shutdown. Affected files are
728 silcd/server_internal.h and silcd/server_util.c.
730 * Notify distribution to backup routers was missing from
731 the silc_server_send_notify_dest function which caused
732 desyncing problems with backup router. Affected file is
735 * The client's channel removing was working wrong on
736 backup router. It assumed that it doesn't know global
737 information but backup router does know. For this reason
738 it could remove channel when it wasn't supposed to do that.
739 Affected file silcd/server.c and silcd/server_util.c.
741 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
743 * Stop for a couple seconds after badkup router has become
744 primary router. Affected file silcd/server.c.
746 * Added silc_server_remove_servers_by_server, which is used
747 to remove servers originated from some other server. Also
748 clients of those servers can be removed too. Affected file
749 silcd/server_util.[ch].
751 * When removing clients after a server has signed of remove
752 also all servers behind that server (unless they are known
753 to be available locally), and send SERVER_SIGNOFF for each
754 of the server separately. Also the signed off clients are
755 sent now separately per signed off server. The affected files
756 are silcd/server.c and silcd/server_util.[ch].
758 * All servers added with silc_idlist_add_server must always
759 have both "router" and "connection" pointers set. Otherwise,
760 bad server entries may be left around in the cache.
761 Affected file silcd/command_reply.c.
763 * Do not create the channel key in NEW_CHANNEL packet
764 processing if the channel is empty. Affected file
765 silcd/packet_receive.c.
767 * Completed backup router support for standalone routers.
768 Supports also servers in the cell that do not use the backup
771 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
773 * Fixed a bug in silc_string_regexify which did not add '^'
774 at the start of each string, and thus the matching was
775 not explicit. For example ban list iikone@*!*@* would
776 match also "priikone", which is wrong, it would have to be
777 *iikone@*!*@* to match also "priikone". Affected
778 file lib/silcutil/unix/silcunixutil.c.
780 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
782 * Enable all local server connections before updating client
783 caches when we've become backup router. Otherwise, signoff
784 packets may not reach the clients. Affected files are
785 silcd/server.c and silcd/server_util.[ch].
787 * Fixed a bug in version string parsing which could crash
788 the program with specially formatted version string.
789 Bug reported and patch provided by Ville Räsänen. Affected
790 file lib/silcutil/silcutil.c.
792 * Handle the disconnection immediately when DISCONNECT
793 packet is received in server. Affected file silcd/server.c.
795 * Primary router now waits a short time (10 seconds) for
796 backup router connection before accepting any other
797 connection (except local). Affected file silcd/server.c,
800 * Fixed a crash in client libary in NICK_CHANGE notify when
801 NICK_CHANGE arrived for client entry we are resolving
802 currently. Affected file lib/silcclient/client_notify.c.
804 * Call the sconn->callback completion even if error had
805 occurred. Start reconnecting always if connection to
806 primary router fails during backup router protocol.
807 Affected files silcd/server.c and server_backup.c.
809 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
811 * Added functions silc_server_send_opers and
812 silc_server_send_opers_notify to send packets stricly
813 to operators. Added macro SILC_SERVER_SEND_OPERS macro
814 to send variable argument notify to operators.
815 Affected files silcd/packet_send.[ch] and silcd/server.h.
817 * Removed UMODE rights checking with UMODE_CHANGE notify.
818 Affected file silcd/packet_receive.c.
820 * Server/router operator now receives notify when network
821 switches to backup router and when it resumes the use of
822 primary router. Affected file silcd/server.c and
823 silcd/server_backup.c.
825 * Fixed the updating of client information after backup
826 resuming protocol is over; update all except local clients
827 to the new primary router. The affected file is
830 * Added support for closing active connections in rehash
831 that were unconfigured by the user. Supports currently
832 closing server and router connections. Affected file
835 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
837 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
839 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
840 is NULL since seems that on some platforms NULL is allowed
841 and on some it's not. Fallback encoding is used instead.
842 Affected file lib/silcutil/silcstrutil.c.
844 * Fixed statistics updating for incoming server connection
845 which could cause problems when re-connecting. Affected
848 * Preliminary backup router support for standalone router
849 added. Affected files in silcd/.
851 * Mark server connections in backup router disabled before
852 and after backup protocol. Affected file is
853 silcd/server_backup.c.
855 * Added support for reconnecting to remote server connection
856 even if the protocol fails, and if the configuration wants
857 us to keep trying to connect anyway.
859 Server connection is not allowed to backup router if
860 backup router does not have connection to primary router yet.
862 Affected file is silcd/server.c.
864 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
866 * Added silc_client_udpate_server function to update changed
867 server info. Affected file lib/silcclient/idlist.[ch].
869 * Added check for server entries that are being resolved when
870 notify is received. If being resolved, handle the received
871 notify only after it's resolved so that all notifys are
872 handled in same order as received from the server.
874 Added similar resolver check to channel entries. Every
875 notify that cause resolving of any information that affects
876 channel entry marks the channel entry in waiting state.
877 After whatever resolving is over the waiters are signalled
878 and only then the notifys are handled in the same order
879 as delivered from the server.
881 Affected files are lib/silcclient/idlist.[ch], and
884 * Fixed KILLED notify handling in normal server. Affected
885 file silcd/packet_receive.c.
887 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
888 is locally connected, or was locally connected (but may
889 be detached and connection is not active). Added also
890 SILC_IS_LOCAL for checking this status. Affected files
891 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
892 silcd/server.c and silcd/server_internal.h.
894 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
896 * Don't send or handle TOPIC_SET if topic is already set and
897 is same as being set. Affected files silcd/command.c and
898 silcd/packet_receive.c.
900 * Fixed CMODE change rights checking to work correctly when
901 removing modes by operator. Affected file is
904 * Fixed some handling with New Channel packet in router and
905 fixed some CMODE_CHANGE notify handling in server and router.
906 Affected file is silcd/packet_receive.c.
908 * Changed "disconnect" client operation to include the
909 reason of the disconnection and optional disconnection
910 message. Affected file lib/silcclient/silcclient.h.
912 * Made the compilation of lib/contrib/ stuff conditional.
913 Affected files configure.in.pre, lib/contrib/Makefile.am.
915 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
917 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
918 to the sender of the notify too, to avoid situation where two
919 notifys are in the network at the same time going to oppsite
920 directions. Affected file silcd/packet_receice.c.
922 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
924 * Delete the client from channel even if the cilent->id is
925 NULL. It was possible that client was deleted without
926 removing from channels (theoretically at least). Affected
927 file silcd/server.c and silcd/server_util.c.
929 * Free the client data too when resuming is not successful.
930 Affected file silcd/packet_receive.c.
932 * Merged some code from c0ffee's silc-plugin. Affected files
933 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
935 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
936 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
937 to the primary router connection, the other one returns
938 TRUE if packet must be broadcasted to network.
940 * All notifys that are destined to primary router (to network)
941 are now automatically sent to backup routers even if the
942 router is standalone (and has backup router). Affected files
945 * Added --without-irssi and --without-silcd configuration
946 options for disabling the compilation of these applications.
947 Affected file configure.in.pre and prepare.
949 Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
951 * Implemented SILC_STRING_BMP and SILC_STRING_UNIVERSAL for
952 UTF-8 encoding and decoding. Added also new encodings
953 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
955 Added also SILC_STRING_LANGUAGE which is language and charset
956 specific encoder and decoer for those platforms that support
957 iconv(). It can convert the UTF-8 to and from the locale
958 specific character set.
960 Affected file lib/silcutil/silcstrutil.[ch].
962 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.
964 * Added function silc_get_command_name to the file
965 lib/silcutil/silcutil.[ch].
967 * Improved the server debug output a bit. Affected files are
970 Wed Jun 19 17:46:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
972 * Save the channel passphrase when received succesful JOIN
973 command reply from router, on normal server. Otherwise
974 joinig +a channels from normal server is not possible.
975 Affected file silcd/command.c.
977 * Fixed a bug in TOPIC_SET notify handling. The notifier
978 may be other than client too, like server or channel.
979 It expected it to always be only client and ignored the
980 notify. Affected file silcd/packet_recieve.c.
982 * Removed some (unnecessary) debug printing from
983 lib/silccore/silcid.c and lib/silccore/silcargument.c.
985 * Do not force CMODE_CHANGE when server is announcing new
988 Router announces stuff only after server reannounces channel
989 after CHANNEL_CHANGE notify.
991 These fixes optimizes the announcing procedure, and perhaps
992 fixes some problems too. Affected file silcd/packet_receive.c.
994 * Fixed SERVER_SIGNOFF sending to local clients. It was
995 totally broken and sent the notify to all local clients,
996 instead of only to those that was on same channel as the
997 signing off clients. Affected file silcd/server_util.c.
999 * Added -D option to server. It can be used to give debug
1000 level. The levels are from 0 - 99, and are predefined for
1001 smooth server debugging. (see silcd.c for the predefined
1002 levels). Affected file silcd/server.c.
1004 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1006 * Fixed a bug in Irssi SILC client to close the connection
1007 properly when disconnecting from server. Affected file
1008 irssi/src/silc/core/client_ops.c.
1010 Tue Jun 18 17:14:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1012 * When authenticating as founder during JOIN command, check
1013 that the one authenticating becomes the only founder on the
1014 channel. Affected file silcd/command.c.
1016 * Better checking for founder mode setting when CUMODE_CHANGE
1017 notify is received. Affected file silcd/packet_receive.c.
1019 * Close all connections when shutting down the server by sending
1020 DISCONNECT packet. Close all listeners too when shutting
1021 down the server. Affected file silcd/server.c.
1023 * Handle DISCONNECT packet correctly in client library by
1024 calling the "disconnect" client operation. Affected file
1025 lib/silcclient/client.c.
1027 * Handle local errors correctly during resuming. Affected
1028 file lib/silcclient/client.c.
1030 Tue Jun 18 10:26:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1032 * The log file is not dupped internally anymore in
1033 lib/silcutil/silclog.c. Fixed memory leaks too.
1035 * The scheduler now dispatches all pending timeout tasks
1036 when it is uninitialized with silc_schedule_uninit.
1037 Affected file lib/silcutil/silcschedule.c.
1039 Mon Jun 17 21:30:55 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1041 * Added --enable-stack-trace option to configure. Added
1042 memory allocation stack trace support. Added files
1043 lib/silcutil/stacktrace.[ch]. Affected files are
1044 lib/silcutil/silcmemory.[ch].
1046 * Fixed memory leaks from libraries and server. Affected
1047 files around the tree.
1049 * Reverted back a fix made to CUMODE which broke it.
1050 Affected file silcd/command.c.
1052 Sun Jun 16 11:49:45 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1054 * Added SILC_MESSAGE_FLAG_UTF8 to the protocol specs and the
1055 core library, and implemented it. All textual messages SHOULD
1056 use this flag and the message MUST be UTF-8 encoded.
1057 All text messages sent by Irssi SILC client are now UTF-8
1058 encoded (regardless whether the terminal supports UTF-8 or not).
1059 Affected files are lib/silccore/silcchannel.h,
1060 irssi/src/silc/core/silc-servers.c, silc-channels.c and
1063 Sat Jun 15 18:23:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1065 * Added lots of new statistics updating that was missing from
1066 the server and router code. Affected files in silcd/.
1068 * Sending SIGUSR1 signal to server now dumps the current
1069 server statistics into /tmp directory. Affected file is
1072 * ROBODoc documented the lib/silccrypt/silchash.h. Improved
1073 the SILC Hash Interface also. Added new functions
1074 silc_hash_get_name, silc_hash_init, silc_hash_update and
1075 silc_hash_final. Affected file lib/silccrypt/silchash.c.
1077 Sat Jun 15 12:09:14 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1079 * Added some better info printing for client during connecting.
1080 Affected file silcd/server_util.c.
1082 * Implemented the SILC_CHANNEL_UMODE_QUIET mode that can be used
1083 to silence a user on a channel. Affected files are
1084 lib/silcclient/client_channel.c, irssi/src/silc/core/client_ops.c,
1085 irssi/src/fe-common/silc/module-formats.[ch], silcd/command.c
1086 and silcd/packet_receive.c.
1088 * Fixed a fatal bug in handling of malformed command payload.
1089 Affected file silcd/command.c.
1091 * Fixed a double free when announcing channel users to router.
1092 Affected file silcd/server.c.
1094 * After successful authentication to channel founder mode, check
1095 that there isn't anyone else with founder mode on the channel.
1096 The one that authenticated will become founder and anyone
1097 else is demoted. Affected file silcd/command.c.
1099 * Added error printing of any error that has occurred during
1100 any command in client library. Affected file is
1101 irssi/src/silc/core/client_ops.c.
1103 * Removed some error printing from the client library and left
1104 it for the application to worry (from the error status it
1105 receives in 'command' client operation. Affected file is
1106 lib/silcclient/command.c.
1108 Fri Jun 14 22:59:02 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1110 * Added new status types KEY_AGREEMENT_ALREADY_STARTED and

1606 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1608 * Redefined the Status Payload to include now two 8 bit fields,
1609 instead of one 16 bit field. This now makes it possible to
1610 send list of errors. Updated the protocol specs and the code
1611 in core library, client library and server. Protocol TODO #1.
1612 Affected files are lib/silccore/silccommand.[ch],
1613 lib/silcclient/command_reply.[ch], silcd/command.c,
1614 silcd/command_reply.c and silcd/packet_receive.[ch].
1616 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1618 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
1619 must be handled by the application and should tell the application
1620 that an error message was already printed, and it should print the
1621 config coords (line, filename, ...). Affected files are
1622 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
1624 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
1625 server config parsing code more readable.
1627 Fixed a bug in the fetch_logging() config callback.
1629 Affected files is silcd/serverconfig.c.
1631 * Drop root privileges when started in foreground. Don't drop them
1632 if debugging also. Affected file is silcd/silcd.c.
1634 Mon Apr 8 17:00:41 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1636 * Added more IM-like features by introducing new user modes
1637 for setting various presence information. Added new modes:
1638 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
1639 specs and code. Protocol TODO #19. Affected files are
1640 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
1641 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
1643 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1645 * Added STATS command to the protocol after all, to return
1646 various statistical information about the network. It can
1647 be used by clients to retrieve statistical information, and
1648 servers may use it to to fetch cell and network wide
1649 statistics from router. Updated the protocol specs and
1650 implemented it to the server. Protocol TODO #16.
1651 Affected files are lib/silccore/silccommand, silcd/command.[ch],
1652 silcd/command_reply.[ch].
1654 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1656 * The LIST command reply in client libary now adds new channel
1657 entry if the returned channel doesn't exist yet in cache,
1658 and returns the channel entry to the application in the
1659 command_reply client operation. Affected file is
1660 lib/silcclient/command_reply.c.
1662 * Changed the channel message payload's MAC generation to
1663 include the IV in the MAC as well. This way all relevant
1664 parts of the channel message payload are authenticated also
1665 with the channel message MAC (and not only by packet MAC).
1666 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1667 Affected file is lib/silccore/silcchannel.c.
1669 * Fixed the SKE to save the remote version, since the
1670 silc_ske_parse_version mistakenly checked wrong version,
1671 after it replaced the start payload. Affected files are
1672 lib/silcske/silcske.[ch].
1674 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1676 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
1677 string utility functions. Added there also new functions
1678 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
1679 Affected files lib/silcutil/silcstrutil.[ch].
1681 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
1682 files are lib/silcutil/silcstrutil.[ch].
1684 * Defined that the security property fields in SKE SHOULD be
1685 UTF-8 encoded, defined that version string MUST be US-ASCII
1686 encoded, defined that passphrases sent in connection
1687 authentication protocol MUST be UTF-8 encoded. Implemented
1688 these to the client and server. Defined also that other
1689 passphrases sent in the protocol MUST be UTF-8 encoded.
1690 Affected files are lib/silcske/silcske.c,
1691 lib/silcclient/protocol.c, silcd/protocol.c,
1692 silcd/serverconfig.c, and lib/silccore/silcauth.c.
1694 * Changed the silc_client_close_connection interface to not
1695 need the SilcSocketConnection which should not be visible
1696 to application. Affected files are lib/silcclient/client.c
1697 and lib/silcclient/silcclient.h.
1699 * Rewrote the text for Private Message Key Payload in the
1700 protocol specification. Protocol TODO #11.
1702 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1704 * Upgraded the protocol version to 1.1, updated protocol specs
1707 * Added the nickname as new argument to NICK_CHANGE notify and
1708 added it to protocol specs and implemented it to client and
1709 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
1710 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
1711 lib/silcclient/client_notify.c.
1713 * Added the killer's client ID to the KILLED notify and added
1714 it to protocol specs and implemented it to client and server.
1715 Protocol TODO #13. Affected files are silcd/command.c,
1716 silcd/packet_receive.c, packet_send.[ch],
1717 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1718 The killer's client entry is now returned to application in
1719 the `notify' client operation.
1721 * Fixed the Max Argument fields that had too large value set
1722 in the protocol specs. Protocol TODO #14.
1724 * Added the LEAVE command reply to return the ID of parted
1725 channel. Updated protocol specs and implemented it to the
1726 client and server. Protocol TODO #15. Affected files are
1727 silcd/command.c, lib/silcclient/command_reply.c. The channel
1728 entry is now returned to application in the `command_reply'
1731 * Rewrote the version SKE version checking in client libary
1732 and in server to use the silc_parse_version_string. Affected
1733 files are lib/silcclient/protocol.c, silcd/protocol.c.
1735 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
1736 commands that was missing it, and updated protocol specs and
1737 the server implementation. Protocol TODO #10. The affected
1738 file is silcd/command.c.
1740 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1741 generic reply to a generic request (REQUEST flag), and
1742 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1743 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1744 to define the payload for DATA flag. Added the flags to
1745 the implementation. Protocol TODO #9. Affected file is
1746 lib/silccore/silcchannel.h.
1748 Changed the client library to return the message length
1749 to application as well in the channel_message and private_message
1750 client operations. Affected files are
1751 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
1752 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
1753 and lib/silcclient/client_ops_example.c.
1755 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
1756 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
1757 the channel. Updated protocol specs and impelemented this
1758 to client and server. Protocol TODO #6. Affected files are
1759 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
1760 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
1762 Added new options m and M to CMODE command in Irssi SILC
1763 client to set these modes.
1765 * Deprecated all administrative commands from SILC protocol
1766 since they are highly implementation specific commands.
1767 Updated protocol specs. Moved the old commands in
1768 implementations to private range of command types. Affected
1769 files are silcd/command.c, lib/silcclient/command.c and
1770 lib/silcclient/command_reply.c. Protocol TODO #8.
1772 * Fixed a bug in server where sending unknown command crashes
1773 the server. Affected file silcd/command.c.
1775 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1777 * Added SILC_PROTOCOLVERSION macro to check protocol version
1778 of a socket connection. The affected file is
1779 lib/silcutil/silcsockconn.h.
1781 * Added better error logging in rekey protocol. Affected file
1784 * Do not check public key types in SKE during rekey. Affected
1785 file lib/silcske/payload.c.
1787 * Fixed the rekey protocol with PFS, which was totally broken.
1788 Affected file silcd/protocol.c.
1790 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1792 * Some client implementations quit network by doing first LEAVE
1793 and then immediately SIGNOFF (like Bombyx). We now do check
1794 after a short time after LEAVE notify and check whether the
1795 client is still valid after LEAVE, and if not we remove it from
1796 cache. Affected file is lib/silcclient/client_notify.c.
1798 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1800 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1801 it's good not to have security holes here.
1803 * Fixed a negative refcount situtuation for the config context.
1804 Affected file is silcd/serverconfig.c.
1806 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1808 * ROBOdoc documented lib/silcutil/silcutil.h.
1810 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1812 * Optimized even more the SilcPacketContext structure. Now
1813 totally saved 16 bytes of memory per context after optimization.
1814 Affected files are lib/silccore/silcpacket.[ch].
1816 * Made strict checks for valid SILC IDs. Affected file is
1817 lib/silccore/silcid.c.
1819 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1821 * Changed the object argument for silc_cipher_register,
1822 silc_hash_register, silc_hmac_register and silc_pkcs_register
1823 to const. Affected files are lib/silccrypt/silccipher.[ch],
1824 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1826 * Changed the silc_get_username and silc_get_real_name to
1827 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1829 * Fixed the Irssi SILC Client to use the silc_get_username and
1830 silc_get_real_name insted of glib routines since the glib
1831 routines only corrupt stack. Fixes the Irssi SILC to work in
1832 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1834 * Fixed the Irssi to not use g_get_home_dir since it crashes
1835 or returns garbage on cygwin and corrupts stack. Added function
1836 get_home_dir to Irssi routines. Affected files are
1837 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1839 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1841 * Made some structure optimizations. SFTP memory FS MemFSEntry
1842 entry structure. Optimized SilcTask structure. Optimized
1843 SilcPacketContext structure.
1845 Affected files lib/silcsftp/sftp_fs_memory.c,
1846 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1848 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1850 * And yet again reverted back the config thing since Johnny
1851 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1854 * Fixed memory leaks from config object. Affected files are
1855 silcd/serverconfig.[ch].
1857 * Added support for adding new connections to the server in rehash.
1858 After rehash they take effect.
1860 Added support for changing the maximum allowed connections in
1861 rehash. The number can grow but going smaller is not supported.
1863 Added function silc_server_num_sockets_by_remote to the
1864 silcd/server_util.[ch].
1866 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1868 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1870 * Added preliminary checking during config parsing for a valid
1871 public/private key and removed further checks in the code.
1872 Affected files are silcd/serverconfig.[ch], server.c.
1874 * Moved functions silc_server_drop() and silc_server_daemonise()
1875 from server.c to silcd.c since they are stricly related to
1876 the application activity.
1878 * Reverted a small part of the automatic ref/unref since
1879 it caused a double unref in some situations. Affected
1880 files are silcd/silcd.[ch], server.c, serverconfig.c.
1882 * Added some .cvsignore files in the lib directory.
1884 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1886 * Fixed silc_net_gethostbyaddr to correctly resolve by
1887 address. Affected file lib/silcutil/silcnet.c.
1889 * Fixed the notify relaying to client. The HMAC to be used
1890 with relayed packets ws wrong and caused decryption failure
1891 at the client end. Affected file is silcd/packet_receive.c.
1893 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1895 * Created new branch silc_protocol_1_0_branch.
1897 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1899 * Changed the silc_server_config_* routines to be SilcServer
1900 independent. They are now officially application specific code
1901 and not part of generic server implementation. Affected files
1902 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1904 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1906 * Added automatic referencing of config context in the
1907 silc_server_config_alloc, and automatic unreferencing in the
1908 silc_server_config_destroy. Affected files are
1909 silcd/serverconfig.[ch], silcd/silcd.c.
1911 * Fixed the silc_log_quick handling in the logging routines.
1912 It didn't log quickly when it was TRUE. Affected file is
1913 lib/silcutil/silclog.c. Also the flush delay was set even
1914 if it was 0 in config file. Affected file is
1915 silcd/serverconfig.c.
1917 * Added support for changing key pair of the server in rehash.
1918 Affected file silcd/server.c.
1920 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1922 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1923 too early, before getting the channel entry. Affected file
1924 is silcd/packet_receive.c.
1926 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1928 * Added functions silc_server_config_[ref/unref], these are used
1929 to prevent that the config object is destroyed.
1931 No longer directly affect global variables silc_log_quick and
1932 silc_log_delay, they are first cached inside the config object
1933 and then applied with silc_server_config_setlogfiles().
1935 silc_server_config_set_defaults() is now internal to
1936 serverconfig.c, there are no reasons to show this internal stuff
1939 Affected files are silcd/serverconfig.[ch].
1941 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1942 fprintf's to stderr, since some code may be executed again after
1943 the server went into the background. Affected files are
1946 * Added rehash support. Added function silc_server_rehash() that
1947 will perform all the basic tasks of the rehashing procedure.
1949 * Added command line option `-x, --hexdump'. This will enable the
1950 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1951 The option `--hexdump' implies `--debug'.
1953 * Fixed a bad bug in the logging APIs (silcutil library) where
1954 the application would crash after calling silc_log_reset_all().
1956 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1958 * Fixed the KICKED notify handling in client library to
1959 correctly remove the channel and all entries from the
1960 channel when I was kicked. This bug crashed the client.
1962 Fixed yet another but in KICKED notify handling to remove
1963 the kicked client correctly from the channel.
1965 Affected file is lib/silcclient/client_notify.c.
1967 * Fixed a minor bug in looking up correct client entry
1968 in KICKED notify in server. Affected file is
1969 silcd/packet_receive.c.
1971 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1972 sources correctly to distribution. Fixes --with-gmp option.
1974 * Removed the manual rehashing from ID Cache, and changed it
1975 to use the SILC Hash Table's auto rehash feature. Affected
1976 file is lib/silccore/silcidcache.c.
1978 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1980 * Fixed a bug in the silc_client_nickname_format function that
1981 handles the multiple same nickname formatting. Two clients
1982 with same nickname caused problems after the first one left
1983 and rejoined. It didn't format the nickname correctly.
1984 Affected file is lib/silcclient/idlist.c.
1986 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1988 * Don't change the topic if olod topic is same as new one.
1989 Affected file is silcd/packet_receive.c.
1991 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1993 * Added cross-reference support to the SILC Documentation
1994 generator. All types across all HTML files are now cross-
1995 referenced. Affected files util/robodoc/generator.c and
1996 scripts/silcdoc/silcdoc.
1998 * Added file lib/silcutil/silctypes.h to include all the
1999 arithmetic type definitions and some macros. Removed
2000 includes/bitmove.h and moved macros to silctypes.h.
2002 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2004 * Merged bugfixes for Irssi SILC client from irssi.org CVS.

2009 now returns the type of the ID to the sent pointer. Affected
2010 file is lib/silccore/silcid.[ch].
2012 * Added check for CMODE_CHANGE notify type that mode change is
2013 allowed by the sender. Affected file silcd/packet_receive.c.
2015 * Added check for CUMODE_CHANGE notify type that mode change is
2016 allowed by the sender. Affected file silcd/packet_receive.c.
2017 Added the ID type as CUMODE_CHANGE notify type as argument
2018 to the `notify' client operation. Affected files are
2019 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
2021 * Added function silc_client_add_server to the client library.
2022 Added support for resolving also channel and server info when
2023 received unknown entity in notify packet. Affected files are
2024 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
2026 * Added function silc_command_get_status to return the command
2027 status from the command reply's argument payload. Affected files
2028 are lib/silccore/silccommand.[ch].
2030 * Added check for KICKED notify type that the kicking is
2031 allowed by the client. Affected file silcd/packet_receive.c.
2033 * Created function silc_get_input which can be used to get input
2034 (echo on or off) from user on command line. Affected files are
2035 lib/silcutil/silcutil.[ch].
2037 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2039 * Optimized silc_server_packet_relay_to_channel function.
2040 Added new function silc_channel_message_payload_encrypt which
2041 can be called directly if channel message payload needs to
2042 be encrypted and is already encoded (no need to call _encode
2043 function). Packet relaying is now done by router without any
2044 extra memory allocations. Affected files are
2045 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
2046 silcd/packet_send.c.

2056 the client. Affected file silcd/packet_receive.c.
2058 * Changed the silc_server_client_on_channel to return the
2059 SilcChannelClientEntry as well. Moved the function
2060 silc_server_check_cmode_rights to server_util.[ch].
2061 Affected files are silcd/server_util.[ch], silcd/command.c.
2063 * Added function silc_server_check_umode_rights to check whether

2065 UMODE_CHANGE notify type that the umode change is allowed
2066 by the client. Affected files are silcd/server_util.[ch],
2067 silcd/packet_receive.c and silcd/command.c.
2069 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2071 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
2072 ID length. It ignored that ID can be IPv6 based as well.
2073 Affected file lib/silccore/silcpacket.h.
2075 * Fixed the silc_id_id2str and silc_id_str2id to take the
2076 IPv6 address offset's into consideration. Affecte file is
2077 lib/silccore/silcid.c.
2079 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2082 NULL context they may receive. The affected file is
2083 lib/silcutil/unix/silcunixschedule.c.
2085 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
2087 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
2088 can specify different directory with --home command line
2089 parameter. Affected files irssi/src/silc/core/client_ops.c,
2092 * SILC-specific commands aren't now executed if the active server
2093 isn't of SILC-type, so there won't be problems with having
2094 IRC and SILC protocol support in same client. Affected files
2095 irssi/src/silc/core/silc-channels.c, silc-servers.c,
2098 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2100 * Improved the signal support in SILC Schedule. Added new
2101 function silc_schedule_signal_call which is used by application
2102 to mark a signal to be called. It is now safe to perform
2103 any kind of tasks in signal callbacks since it is guaranteed
2104 that the application specified signal callback is called
2105 after the signal is over. Affected files are
2106 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
2108 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2110 * Added `name' field to SilcChannelPrivateKey to represent
2111 application given name for the key. Moved also the context from
2112 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
2113 Added the `name' argument also to the function
2114 silc_client_add_channel_private_key.
2116 Added function silc_client_current_channel_private_key to set the
2117 current channel private key in use.
2119 Added "change" command to KEY command which can be used to change
2120 the current channel private key. Bound the command also to
2121 alt+K (Alt+Shift+k).
2123 Also affected files lib/silcclient/client_channel.c,
2124 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
2126 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2128 * Added silc_rng_get_byte_fast function in to the
2129 lib/silccrypt/silcrng.[ch].
2131 * Changed the interface of silc_packet_assemble and the
2132 silc_packet_send_prepare. If silc_packet_assmble is now
2133 called the application does not call silc_packet_send_prepare
2134 because the library will call it automatically. These
2135 interfaces now also return a reference to the outgoing buffer
2136 which includes the assembled packet, which the application can
2137 use to encrypt the packet.
2139 Affected files are lib/silccore/silcpacket.[ch],
2140 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
2141 silcd/packet_send.c, server_backup.c and packet_receive.c.
2143 * Fixed a packet sending bug on very high load, where outgoing
2144 packet queue wasn't handled correctly and packets got corrupted.
2145 Affected files are lib/silcutil/*/silc*sockconn.c,
2146 lib/silcclient/client.c and silcd/server.c.
2148 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2150 * Added macro SILC_PACKET_DATALEN which can be used during
2151 packet assembling to check whether the data to be added to
2152 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
2153 len is truncated until it fits it.
2155 Added checks for maximum length of channel message payload and
2156 private message payload also.
2158 Added checks for maximum packet length in server and in
2161 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
2162 lib/silcclient/client.c, lib/silccore/silcchannel.c and
2163 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
2164 lib/silcclient/client_prvmsg.c.
2166 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2168 * Added silc_server_packet_queue_purge call to the
2169 silc_server_disconnect_remote to assure that all data in the
2170 queue before disconnecting is sent to the network. Affected
2171 file silcd/server.c.
2173 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2175 * Added the deleting of server's own ID cache entry to the
2176 silc_server_free function. Free also everything else that
2177 has been allocated in silc_server_init. The affected file
2180 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2182 * Added functions silc_parse_version_string, silc_version_to_num,
2183 and silc_ske_parse_version to parse SILC protocol style version
2184 strings. Affected files lib/silcutil/silcutil.[ch] and
2185 lib/silcske/silcske.[ch].
2187 * Added new configuration params: version_protocol, version_software
2188 and version_software_vendor to specify what version the remote
2189 host must at least be to be able to connect to server. The vendor
2190 string can be regex matched too. Added new function
2191 silc_server_connection_allowed to check maximum number of allowed
2192 connections, and allowed versions for incoming connections.
2193 Affected files are silcd/server.c, server_util.[ch] and
2196 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2198 * Added preliminary support for signals in scheduler. The
2199 signals we care about are now blocked always when the scheduler
2200 is locked. This way we can synchronise the use of signal with
2201 scheduler. It is guaranteed that when signal occurs the scheduler
2202 is not locked, and thus new tasks can be safely added to the
2205 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
2206 to silc_schedule_internal_init and silc_schedule_internal_uninit.
2207 Added new platform specific routines
2208 silc_schedule_internal_signals_[un]block and
2209 silc_schedule_internal_signal_[un]register.
2211 Added new functions to SILC Schedule API:
2212 silc_schedule_signal_[un]register. Each signal that application
2213 is going to use should be registered to the scheduler.
2215 Affected files are lib/silcutil/silcschedule.[ch],
2216 lib/silcutil/*/silc*schedule.c.
2218 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2220 * Check for unauthenticated client and server in the
2221 silc_server_new_client and silc_server_new_server functions.
2222 Affected file silcd/packet_receive.c.
2224 * Added function silc_string_is_ascii to check whether given
2225 string is 7-bit ASCII string. Affected files are
2226 lib/silcutil/silcutil.[ch].
2228 * Added function silc_id_is_valid_server_id into the
2229 silcd/serverid.c and added checking for valid Server ID's in
2230 silc_server_new_server. The Server ID must always be based
2231 on the server's public IP address.
2233 * Added logging of DISCONNECT packet message in the server.
2234 Affected file silcd/server.c.
2236 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2238 * Changed all library interfaces that use Global RNG to also
2239 accept SilcRng as argument. Affected files are
2240 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
2241 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
2242 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
2243 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
2244 lib/silccrypt/rsa.c.
2246 * Added function silc_pkcs_generate_key to the
2247 lib/silccrypt/silcpkcs.[ch] for applications so that they
2248 don't need to do pkcs->pkcs->init calls anymore.
2250 * Remove SilcSocketConnection from the SFTP API since it really
2251 wasn't needed there. The application has the information
2252 saved in its contexts anyway and the SFTP layer doesn't need
2253 know about it. Affected files lib/silcsft/silcsftp.h and
2254 lib/silcsftp/sftp_[server/client].c.
2256 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
2257 The SilcSimContext is not SilcSim.
2259 * Fixed possible buffer overflows in silc_id_render in the
2260 lib/silcutil/silcutil.c.
2262 * On EPOC the global crypto module lists are not used at all
2263 in the crypto library. Added support for using the constant
2264 algorithm list on EPOC. Affected files are
2265 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
2268 * Fixed the handling of third parameter of KICKED notify, since
2269 it was mistakenly updated to SILC Protocol 1.0 even though it
2270 is to be included in 1.1. Since it is not in 1.0 it is not
2271 mandatory, and this fix now handles it only if it is provided,
2272 and it is not error if it is not provided. Affected file
2273 lib/silcclient/client_notify.c.
2275 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2277 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
2278 client. Affected file irssi/src/silc/core/client_ops.c.
2280 * Merged with Irssi 0.8.4 from irssi.org CVS.
2282 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2284 * Check for valid socket connection in client entries before
2285 sending any messages. Fixes a crash, but doesn't fix some
2286 other underlaying bug that is lurking there. Affected
2287 file silcd/packet_send.c.
2289 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
2291 * $usermode, $cumode and $cumode_space expandos shouldn't do
2292 anything with non-SILC server records. Affected file
2293 irssi/src/silc/core/silc-expandos.c
2295 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2297 * Fixed the silc_net_check_[host/local]_by_sock to support
2298 IPv6 bound sockets as well. Now they can return IPv6 addresses
2299 as well. Affected file lib/silcutil/silcnet.c.
2301 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
2302 Affected lib/silcutil/unix/silcunixnet.c.
2304 * Fixed ID rendering (at least on some platforms, not NetBSD)
2305 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
2307 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2309 * Added silc_hash_public_key and silc_hash_public_key_compare
2310 functions to be used with SilcHashTable. They can be used to
2311 hash public keys and compare public keys in hash table. Affected
2312 file lib/silcutil/silcutil.[ch].
2314 * Added support for specifying multiple public keys for Client
2315 connection section in server configuration file. This makes it
2316 possible to accept multiple public keys from same host, or to
2317 make a section that accepts any incoming host, and have the
2318 accepted public keys listed in the section.
2320 Added functions silc_sever_[find/get]_public_key, added the
2321 support for this actually to all connection sections but only
2322 the Client section is currently allowed to specify multiple
2325 Affected files are silcd/server.c, server_internal.h,
2326 command.c, protocol.c, server_util.[ch], packet_receive.c.
2328 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2330 * Merged Irssi 0.8.2 from irssi.org CVS.
2332 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2334 * If silc_debug is TRUE, also output standard logging messages
2335 to stderr with the debug output.
2337 Made silc_log_reset_all() flushing all channels before returning.
2338 Also fixed some documentation typos.
2340 Affected files are lib/silcutil/silclog.[ch].
2342 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2344 * Fixed the server to check correctly the amount of connections
2345 from single host, by checking also the type of the connection.
2346 Fixed also the comparison of number of connections and number
2347 of allowed connections. Affected files are silcd/server.c,
2350 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2352 * Fixed the USERS command reply to save the user's mode on the
2353 channel as well. Fixed JOIN command reply to check whether a
2354 client is on channel already and not join it twice. Affected
2355 file lib/silcclient/command_reply.c.
2357 * Added new file silc-expandos.c into irssi/silc/core/ to return
2358 various stuff for various signal for the statusbar etc. updating.
2359 Now Irssi SILC client prints channel user modes etc. on the
2362 * The user mode (like server/router operator changes) is now shown
2363 on the Irssi SILC client's statusbar. The affected files are
2364 irssi/src/silc/core/client_ops.c, silc-expandos.c.
2366 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2368 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
2369 to SILC_SCHEDULE_[UN]LOCK macros.
2371 * Added more error printing to logs in server code. Affected
2372 files silcd/server.c and silcd/protocol.c.
2374 * Fixed -S option parsing in Irssi SILC Client. Affected file
2375 irssi/src/silc/core/silc-core.c.
2377 * Added silc_buffer_alloc_size function. Affected file is
2378 lib/silcutil/silcbuffer.h.
2380 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2382 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
2383 constants. Affected files in
2384 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
2387 * Changed the internal SFTP Memory FS table to const. Affected
2388 file lib/silcsftp/sftp_fs_memory.c.
2390 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2392 * Fixed the buffer formatting and unformatting routines to
2393 check the size of 64 bits types with sizeof(). Affected
2394 file is lib/silcutil/silcbuffmt.c.
2396 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2398 * Removed 0.6.x backwards support.
2400 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2402 * Changed all integer type names:
2403 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
2404 to avoid collisions with other libraries using same type names
2407 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2409 * Added `prefer_ipv6' argument to the functions
2410 silc_net_gethostbyname[_async]. If it is TRUE it will return
2411 IPv6 address over IPv4. If FALSE IPv4 address is returned
2412 even if IPv6 address was found. Affected files
2413 lib/silcutil/silcnet.[ch].
2415 * Added support silc_net_create_connection[_async] to fallback
2416 to IPv4 address if IPv6 address could not be used (like if
2417 it doesn't work on a specific system). Affected file in
2418 lib/silcutil/unix/silcunixnet.c.
2420 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2422 * Added silc_schedule_reinit function to do the enlarging
2423 of the max tasks handling capabilities of the scheduler.
2424 Affected files lib/silcutil/silcschedule.[ch].
2426 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2428 * Added automatic extern "C" { ... } for C++ compilers so the
2429 application does not need to define them. Affected file
2430 includes/silcincludes.h.
2432 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
2433 old name went against naming convention. Applications now
2434 include "silcclient.h" instead of "clientlibincludes.h".
2435 Removed includes/clientlibincludes.h, it is redundant now.
2437 * Renamed includes/version.h to silcversion.h.
2439 * Added really preliminary support for OS/2 into the util
2440 library. Only thread & mutex API is implemented, others
2441 are still to be implemented. Created the lib/silcutil/os2/
2442 directory. Created also file includes/silcos2.h.
2444 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2446 * Added preliminary BeOS support into the util library.
2447 Created lib/silcutil/beos/, and implemented all the needed
2448 functions to support SILC on BeOS. Created also file
2449 includes/silcbeos.h.
2451 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
2453 * Added proper initializations to silc's irssi code, so it's
2454 now possible to load it as module. Affected files
2455 irssi/src/silc/core/silc-core.c,
2456 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
2458 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2460 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
2463 * Fixed the silcdoc document generator to correct generate
2464 docs from all kinds of filenames. Affected files are
2465 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
2467 * ROBOdoc documented lib/silcutil/silcmemory.h.
2468 Added also new function silc_memdup.
2470 * Removed lib/silcutil/silcbufutil.h and moved those routines
2471 to the lib/silcutil/silcbuffer.h.
2473 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2475 * Added `user_count' to the SilcChannelEntry which now tells the
2476 number of users on the channel. The user count is now saved
2477 in normal server of global channels as well. Affected files
2478 silcd/server.c, idlist.h, packet_receive.c and command.c.
2480 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
2481 include file utility functions.
2483 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
2484 instead of calling directly OS routines.
2486 * Fixed NICK change printing in Irssi SILC Client. Fixed
2487 KICKED notify printing in Irssi SILC Client. Affected file
2488 irssi/src/silc/core/client_ops.c.
2490 * Fixed a NICK change bug in client library, to not recreate the
2491 client_entry->channels hash table everytime nick is changed.
2492 Affected file lib/silcclient/client.c.
2494 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2496 * ROBOdoc documented the lib/silcske/silcske.h, and improved
2497 the SKE interface a bit.
2499 * Fixed padding problem in PKCS#1. The padding was not actually
2500 random since the random number generator was used incorrectly.
2501 This security bug affects only when encrypting with PKCS#1, and
2502 it is not currently used at all in SILC. SILC only use signing
2503 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
2505 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2507 * Rewrote the notify handling in Irssi SILC client to not call
2508 the events as signals. Fixes problems with Perl support.
2509 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
2511 * Send the auto-nicking NICK command in client library with
2512 little timeout after connecting. The affected file is
2513 lib/silcclient/client.c.
2515 * Added following new config file settings:
2516 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
2517 key_exchange_timeout, conn_auth_timeout, connections_max,
2520 Implemented all the new config settings handling in the server.
2522 Optimized the use of SKE Mutual flag usage. Use it only
2523 if connection authentication protocol is not based in public
2526 Renamed all SilcServerConfigSection* to SilcServerConfig*
2527 to have a bit shorter names.
2529 Affected files silcd/serverconfig.[ch], server.[ch], and
2532 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2534 * Cleaned up the listening sockets code, preparing for the rehash
2535 support. Affected file is silcd/server.c.
2537 * Fixed some output messages. Affected files are silcd/silcd.c,
2540 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2542 * Create lib/doc/silcrng_intro.html document as introduction
2543 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
2545 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2547 * Fixes to the silcd config template. Affected file is
2548 doc/example_silcd.conf.in.
2550 * Removed type casts from silc_calloc(), conforming to the
2551 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
2553 * Removed param_name member from client, server, and router
2554 section structs, now identifying the param directly.
2556 Added CONFIG_FREE_AUTH macro in config file parsing.
2558 Affected files are silcd/serverconfig.[ch].
2560 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
2562 * Fixed command line parameter handling. All SILC initialization
2563 is now done in silc_core_init() which also fixes autoconnecting
2566 Affected files irssi/src/silc/core/silc-core.c,
2567 irssi/src/fe-text/silc.c.
2569 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2571 * Added new configuration options and blocks:
2572 keepalive_secs, reconnect_count, reconnect_interval,
2573 reconnect_interval_max, reconnect_keep_trying and
2574 require_reverser_lookup. Added ConnectionParam block, and
2575 implemented the connection parameters when connecting as
2576 initiator and when accepting connections as responder.
2578 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
2579 whether given configuration value has been given already.
2581 Affected files silcd/serverconfig.[c], server.[c].
2583 * Splitted the doc/example_silcd.conf.in. Separated the crypto
2584 algorithm parts and created new file silcalgs.conf, that
2585 is now included from the example_silcd.conf.in.
2587 * Optimized the silc_server_connect_to_router_second to take
2588 the connection configuration object from the SilcServerConnection
2589 object instead of finding it during the connecting phase.
2590 Added the configuration object to SilcServerConnection struct.
2591 Affected files silcd/server_internal.h, server.c.
2593 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2595 * Add the client on channel after it was resolved at the
2596 channel message receiving, and it was not already on the
2597 channel. Affected file lib/silcclient/client_channel.c.
2599 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2601 * Fixed the public key authentication to allocate always the
2602 destination signature buffer instead of using static buffer.
2603 Affected file silcd/protocol.c.
2605 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2607 * Unified the serverconfig.[ch]'s helper function interface.
2608 Affected file silcd/serverconfig.[ch].
2610 * Removed doc/example_silc.conf.in since it is redundant.
2611 The make install will now install irssi/silc.conf file.
2613 * Added new Passphrase and Publickey authentication methods to
2614 config file, allowing both public key and passphrase based
2615 authentication to be set at the same time.
2617 Added `prefer_passphrase_auth' setting in config file which
2618 can be used to set to prefer passwd auth if both passwd and
2619 public key is set. If not set, public key is preferred.
2620 This has effect only when being initiator (responder will try
2623 Added support for authentication with passphrase and public key
2624 at the same time. The passphrase is tried first always since
2625 it is faster to check.
2627 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2629 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2631 * Merged the new SILC Config library, with the server parsing
2632 support. Read the header file silcconfig.h or the toolkit
2633 documentation for the news. Affected files are
2634 doc/example_silcd.conf.in lib/silcutil/silcconfig.[ch]
2635 silcd/command.c silcd/packet_receive.c silcd/packet_send.c
2636 silcd/protocol.c silcd/server.c silcd/server_backup.c
2637 silcd/serverconfig.[ch] silcd/silcd.c.
2639 * Fixed some silclog documentation. Affected file is
2640 lib/silcutil/silclog.h.
2642 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2644 * The silc_cipher_register, silc_hash_register and
2645 silc_hmac_register now checks if the object to be registered
2646 is registered already. Affected files are
2647 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
2649 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2651 * Merged new irssi from irssi.org's CVS, the version 0.7.99.

2655 * Allow zero length channel messages inside the Channel Message
2656 Payload. Affected file lib/silccore/silcchannel.c.
2658 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
2659 as header filenames.
2661 * Removed lib/silcclient/README and created HTML file
2662 lib/silcclient/silcclient_using.html, which is now included
2663 as part of Toolkit documentation.
2665 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2667 * Fixed CUMODE_CHANGE notify handling to change the mode of
2668 correct client. Affected file lib/silcclient/client_notify.c.
2670 * Make silc_rng_alloc fail if it cannot allocate the sha1
2671 hash algorithm. Affected file lib/silccrypt/silcrng.c.
2673 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2675 * Fixed the file transfer's key agreement payload to include
2676 zero port also if the hostname is NULL because it could not
2679 Call file transfer monitor callback now also if error occurs
2680 during key agreement protocol.
2682 Changed the silc_client_file_send interface to return the
2683 SilcClientFileError instead of session id. The session ID
2684 is returned into pointer provided as argument.
2686 Check that the file exists locally before sending the
2687 file transfer request at all.
2689 Affected file lib/silcclient/client_ftp.c, silcapi.h.
2691 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
2692 error than can occur while key agreement protocol. Affected
2693 file lib/silcclient/silcapi.h.
2695 * Fixed the event_mode CMODE handler to not crash when mode
2696 is changed and +k mode is set in the channel. Affected file
2697 irssi/src/silc/core/silc-channels.c.
2699 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2700 SILC_LOG_WARNING to give out Warning and not Error. Affected
2701 file lib/silcutil/silclog.c.
2703 * Fixed the channel message payload decryption in the function
2704 silc_channel_message_payload_decrypt to not modify the original
2705 buffer before it is verified that the message decrypted
2706 correctly. Otherwise, next time it is called with correct
2707 channel key it won't encrypt since the payload is corrupted.
2708 Affected file lib/silccore/silcchannel.c.
2710 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2712 * Do not constantly resize the window. A fix patch by cras.
2713 Affected file irssi/src/fe-text/screen.c.
2715 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2717 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
2718 Affected file lib/silcutil/silcnet.c.
2720 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2722 * Fixed a bug in hash table internal routine for traversing
2723 the table with foreach callback. The current entry may
2724 become invalid in the callback but it was referenced after
2725 the callback returned.
2727 Do not allow auto rehashing of hash table during the
2728 silc_hash_table_foreach operation, for same reasons as it is
2729 not allowed for SilcHashTableList. Affected files are
2730 lib/silcutil/silchashtable.[ch].
2732 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2734 * Defined DLLAPI into silcincludes.h and silcwin32.h for
2735 Win32 DLL. extern's in header files are now declared with
2738 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2740 * Fixed private message handling. It used some old code that
2741 caused the client to crash. Affecte file is
2742 lib/silcclient/client_prvmsg.c.
2744 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2746 * Added function silc_client_add_channel,
2747 silc_client_replace_channel_id, and removed functions
2748 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2749 from client library.
2751 * Added cross reference of the joined channels to the
2752 SilcClientEntry, and changed the SilcChannelEntry's
2753 users list to SilcHashTable. The affected files are
2754 lib/silcclient/idlist.[ch].
2756 * Fixed a bug in hash table tarversing. While the hash table
2757 is traversed with SilcHashTableList the table must not be
2758 rehashed. It is now guaranteed that auto rehashable tables
2759 are not rehashed while tarversing the list. Also defined that
2760 silc_hash_table_rehash must not be called while tarversing
2761 the table. Added function silc_hash_table_list_reset that must
2762 be called after the tarversing is over. The affected files are
2763 lib/silcutil/silchashtable.[ch].
2765 * Changed all hash table traversing to call the new
2766 silc_hash_table_list_reset in server and in client library.
2768 * Added function silc_client_on_channel to return the
2769 SilcChannelUser entry if the specified client entry is joined
2770 on the specified channel. This is exported to application as
2771 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2773 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2775 * Fixed founder regaining problem with JOIN command on normal
2776 server. The notify for mode change must be sent always and
2777 not only if !cmd->pending. Affected file silcd/command.c.
2779 * Fixed the WHOWAS command's reply sending to support the
2780 lists correctly. Affected file silcd/command.c.
2782 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2784 * When sending JOIN command to router for processing the
2785 sender's old command identifier was not saved back to the
2786 sender's command context, fixed now. The affected file is
2789 * Create the key in JOIN command of the router did not return
2790 the channel key, added check for this. Affected file is
2793 * Fixed a channel ID update bug in JOIN command reply. Do
2794 not directly upgrade the ID but call the function
2795 silc_idlist_replace_channel_id if the ID was changed.
2796 Affected file silcd/command_reply.c.
2798 * Fixed memory leaks from command calling if it would fail.
2799 Affected file silcd/command.c.
2801 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2803 * Applied patches from cras:
2805 Memory leak fixes around libaries, irssi window resize fix,
2806 new silclist.h and silcdlist.h, all extern inline changed to
2809 * Removed dotconf from lib/dotconf, not needed anymore.
2811 * Removed TRQ from lib/trq, not needed anymore.
2813 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2814 with server connections. Later this will be configurable
2815 in config file after new config file is done. Affected file
2818 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2820 * Fixed a crash in server related to channel announcements.
2821 Affected file silcd/server.c.
2823 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2825 * Fixed memory leaks in silc_server_create_new_channel*
2826 functions. Affected file silcd/server.c.
2828 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2829 which ID was changed. This way the router will send the
2830 user list for the channel again, and server won't be in
2831 desync in some rare circumstances. Affected file is
2832 silcd/packet_receive.c.
2834 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2836 * Check for NULL socket pointer in the function
2837 silc_server_packet_send_to_channel_real. Affected file
2838 silcd/packet_send.c.
2840 * Fixed the BAN notify handling to correctly remove ban
2841 list. Affected file silcd/packet_receive.c.
2843 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2845 * Fixed some header addition to Toolkit distribution in
2846 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2848 * Added lib/silcclient/client_ops_example.h as an template
2849 file for application programmers to quickly start using
2850 the SilcClientOperation functions in their application.
2851 Updated the lib/silcclient/README as well to tell about this
2852 nice file made available.
2854 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2856 * Call silc_server_remove_from_channels when removing client
2857 entry when NO_SUCH_CLIENT_ID was received. Affected file
2858 is silcd/command_reply.c.
2860 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2862 * Added server & router operator statistics updating. Affected
2863 file silcd/packet_receive.c and silcd/command.c.
2865 * Fixed the SERVER_SIGNOFF notify handling on normal server
2866 not to save the history information for clients. Same was
2867 fixed earlier in remove_clients_by_server function, but not
2868 here. Affected file silcd/packet_receive.c.
2870 * Raised the default connection-retry count from 4 to 7 in
2871 server. Affected file silcd/server.h.
2873 * Cancel any possible reconnect timeouts when we start the
2874 key exchange. Affected file silcd/server.c.
2876 * Do not reconnect on connection failure when SCONNECT was
2877 given. Affected files silcd/server.[ch].
2879 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2881 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2883 * Fixed the NICK command to always give the unformatted
2884 nickname to the one giving the NICK command. If unformatted
2885 nickname is cached already it will be formatted and the
2886 local entry will always get the unformatted nickname.
2887 Affected file lib/silcclient/idlist.c.
2889 * Fixed some double frees from client library commands.
2890 Affected file is lib/silcclient/command.c.
2892 * Fixed CUMODE command in server to assure that no one can
2893 change founder's mode than the founder itself, there was a
2894 little bug. Affected file silcd/command.c.
2896 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2898 * Removed the SilcClientCommandDestructor from the client
2899 libary, it is not needed anymore. Affected files are
2900 lib/silcclient/silcapi.h, command[_reply].[ch],
2901 client_notify, idlist.c.
2903 * Fixed GETKEY command to first resolve client, and then
2904 resolve the server only if the client was not found, instead
2905 of resolving both at the same time. Affected file is
2906 lib/silcclient/command.c.
2908 * Added silc_client_start_key_exchange_cb and lookup the
2909 remote hostname and IP address before starting the key
2910 exchange with server. The affected file is
2911 lib/silcclient/client.c.
2913 * The server's public key is now saved using the IP address
2914 of the server and not the servername for the filename.
2915 The hostname public key filename is checked as an fall back
2916 method if the IP address based filename is not found.
2918 Fixed the GETKEY command to save the fetched server key
2919 in correct filename.
2921 Print the remote server's hostname now when new key is
2922 received during connection process. Affected file is
2923 irssi/src/silc/core/client_ops.c.
2925 * Return always our own public key to the client if it asks
2926 for it with GETKEY command. Affected file silcd/command.c.
2928 * Removed the use_auto_addr variable from default config
2929 file since it was in wrong section. Affected file is
2932 * Fixed TOPIC_CHANGE notification to not route it when it
2933 was sent using silc_server_send_notify_to_channel function.
2934 Affected file silcd/command.c.
2936 * Fixed silc_server_send_notify_kicked to send the kicker's
2937 Client ID also, it was missing. Affected files are
2938 silcd/command.c, silcd/packet_send.[ch].
2940 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2942 * Do not save client history information in SERVER_SIGNOFF.
2943 Fixes the bug in normal server that it does not detect
2944 the client becoming valid after the server becomes back
2945 online. Affected file silcd/server_util.c.
2947 * Added `sock_error' field into the SilcSocketConnection
2948 context. When error occurs during socket operation (read
2949 or write) the error is saved. Added also new function
2950 silc_socket_get_error to return human readable socket error
2951 message. Affected files are lib/silcutil/silcsockconn.[ch],
2952 lib/silcutil/unix/silcunixsockconn.c, and
2953 lib/silcutil/win32/silcwin32sockconn.c.
2955 * The server now prints the socket error message in the
2956 signoff for client. Affected file silcd/server.c.
2958 * Fixed the `created' channel information sending from router
2959 to server in JOIN command. Checks now whether the channel
2960 really was created or not and set it according that.
2962 Fixed the JOIN command to use the client entry's current
2963 ID during the joining procedure instead of the one it sent
2964 in the command (it is checked though), since it can change
2965 between the packet processing and command processing, and
2966 would just case unnecessary pain in the client end. Affected
2967 file silcd/command.c.
2969 * Fixed a channel key payload sending to use correct channel
2970 ID when the server was forced to change the channel's ID by
2971 router. Router sent the key payload with the old Channel ID.
2972 Affected file silcd/packet_receive.c.
2974 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2976 * Call silc_server_save_channel_key only if the key payload
2977 was provided in the JOIN command's command reply. Affected
2978 file silcd/command_reply.c.
2980 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2982 * Fixed silc_mp_sizeinbase to return the value correctly with
2983 MPI. Affected file lib/silcmath/mp_mpi.c.
2985 * Fixed the stop_server signal to correctly stop the scheduler
2986 and gracefully stop the server when SIGTERM or SIGINT signals
2987 are received. Affected file silcd/silcd.c.
2989 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2991 * Simple handling of TERM and HUP signals. Also added some log
2992 flushing call around. Affected file is
2995 * Fixed small bugs in silclog.c. Now buffering output will take
2996 effect after 10 seconds since startup: This will ensure that
2997 no important startup messages are lost. Also output redirection
2998 will preserve original format ([Date] [Type] message).
2999 Affected file is lib/silcutil/silclog.c.
3001 * Added two options to the config file, in the logging section:
3002 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
3003 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
3005 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3007 * Do not print the warning about log files not being initialized
3008 more than once to avoid excess logging. Affected file is
3009 lib/silcutil/silclog.c.
3011 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
3012 the SIM copying in make install in Makefile.am.pre.
3014 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3016 * Rewritten silclog APIs. Globally interesting changes follows:
3017 silc_log_set_files() changed to silc_log_set_file().
3018 silc_log_set_callbacks() changed to silc_log_set_callback().
3019 ROBOdoc documented silclog header file.
3020 SilcLogCb now returns bool to wether inihibit the default
3021 handler or not (to keep the old behaviour return always TRUE).
3022 The new APIs should also fix the problem of the
3023 silcd_error.log file that was written in the current directory.
3026 Log files streams will remain opened after silc_log_set_file()
3027 call, means less CPU usage notably on high traffic servers.
3028 File streams are now full buffered, and flushed to the disk
3029 every 5 minutes, lesses HD activity and CPU usage.
3030 Messages can be redirected, allowing admins to configure
3031 one single logfile for all server messages.
3032 the silc_log_quick global variable to activate fast-logging.
3033 Affected files lib/silcutil/silclog.[ch]
3035 * Changed some code to conform new silclog APIs. Affected
3036 files are doc/example_silcd.conf.in, silcd/server.c
3037 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
3040 * Fixed a memory leak that could occur in some situations.
3041 Affected file silcd/serverconfig.c.
3043 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3045 * Added the silc_client_del_client to remove the client from
3046 all channels as well. Affected file lib/silcclient/idlist.c.
3048 * Fixed the client library to correctly remove the client
3049 from all channels when the client entry is being destroyed.
3050 Affected file lib/silcclient/client_notify.c, command.c.
3052 * Added auto-nicking support to the client library. If the
3053 applicatio now sets client->nickname it will be sent to the
3054 server after connecting by the library. This way for example
3055 SILCNICK (or IRCNICK) environment variables will have effect
3056 and always change the nickname automatically to whatever
3057 it is wanted. Affected file lib/silcclient/client.[ch].
3059 * Renamed silc_server_command_bad_chars to the
3060 silc_server_name_bad_chars and moved it to the
3061 silcd/server_util.[ch]. Added also new function
3062 silc_server_name_modify_bad to return nickname that
3063 includes bad characters as new nickname without those
3064 bad characters. This check and modify is now used in
3065 silc_server_new_client when the username is initially set
3066 as nickname, so it must be checked to be valid nickname.
3067 Affected file silcd/packet_receive.c.
3069 * The nickname length is now taken from the packet for real
3070 and not trusted to strlen() since it clearly can return
3071 wrong length for nickname including bad characters. This
3072 also applies to channel names. Affected file silcd/command.c.
3074 * Removed the lib/silcsilm/modules directory. Modules are now
3075 compiled into the lib/silcsim. Fixed the copying of the
3076 modules to follow symbolic links in Makefile.am.pre.
3078 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3080 * Fixed silc_string_regexify list creation. Fixes bugs with
3081 BAN and INVITE commands in server. The affected file is
3082 lib/silcutil/unix/silcunixutil.c.
3084 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3086 * Removed the command destructor entirely from the server's
3087 command and command reply routines. It is not needed, and
3088 its usage was buggy and caused crashes. Affected files are
3089 silcd/command[_reply].[ch].
3091 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3093 * Cancel protocol and NULL sock->protocol if timeout
3094 occurred during protocol. Affected file silcd/server.c.
3096 * Cancel protocol timeouts always before calling the final
3097 callback, to assure that after final callback is called
3098 no other state will be called for the protocol anymore.
3099 Affected file silcd/protocol.c.
3101 * Print error log if incoming connection configuration could
3102 not be found. Affected file silcd/server.c.
3104 * Fixed JOIN command to correctly save the founder mode
3105 to the client on normal SILC server, when the channel
3106 was created by the router. Affected file silcd/command.c.
3108 * Fixed LIST command (hopefully) to send correct reply
3109 packets. Affected file silcd/command.c.
3111 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3113 * The silc_packet_receive_process now returns FALSE if the
3114 read data was invalid packet, and TRUE if it was ok.
3116 The server now checks that if unauthenticated connection
3117 sends data and its processing fails the server will close
3118 the connection since it could be a malicious flooder.
3120 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
3122 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3124 * Make sure the warning about error opening a log file is
3125 printed only once and not everytime it fails (produces
3126 too much useless log). Affected file lib/silcutil/silclog.c.
3128 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3130 * Made the silc_server_daemonise() function more readable.
3131 Affected file silcd/server.c.
3133 * Pid file is now optional, the user may comment it out from
3134 the config file. Removed define SILC_SERVER_PID_FILE, we
3135 don't need a default any longer. Affected file
3136 configure.in.pre, lib/Makefile.am.pre.
3138 * Make some use of the pid file. The server now dies at startup
3139 if it detects a valid pid file on his path. The server would
3140 die anyway in this circumstance, because of the bind() failure.
3141 Affected file silcd/silcd.c.
3143 * No longer compiling lib/dotconf.
3145 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3147 * Fixed JOIN command parsing not to crash. Affected file
3148 lib/silcclient/command.c.
3150 * Fied the NICK_CHANGE notify to add the new client entry
3151 even it is resolved. This removes an <[unknown]> nick
3152 thingy bug in the client. Affected file is
3153 lib/silcclient/client_notify.c.
3155 * Do not try to allocate 0 bytes (efence does not like it)
3156 in lib/silccore/silccomand.c when encoding payload.
3158 * Do not take IRCNICK as nickname in Irssi SILC client since
3159 it is not possible to set nickname before hand connecting
3160 the server (TODO has an entry about adding auto-nicking
3163 * Changed the silc_server_command_pending to check whether
3164 there already exists an pending entry with the specified
3165 command, command identifier and pending callback. This is
3166 to fix IDENTIFY and WHOIS related crashes that may register
3167 multiple pending commands with same identifier. Affected
3168 file silcd/command.c.
3170 * Fixed the server to reconnect to the router even if it
3171 was already reconnecting and EOF was received. This to
3172 fix a possibility that the server wouldn't ever try to
3173 auto-reconnect to the router. Affected file silcd/server.c.
3175 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3177 * Fixed the server's password authentication to use the
3178 length of the locally saved password, and not the one
3179 sent in the packet. Affected file silcd/protocol.c.
3181 * Fixed same password authentication problem in the
3182 Authentication Payload handling routines in
3183 lib/silccore/silcauth.c.
3185 * Yet another password authentication problem fixed with
3186 channel password handling in silcd/command.c.
3188 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3190 * If first character of string in silc_parse_userfqdn is '@'
3191 then do not parse it. Affected file is
3192 lib/silcutil/silcutil.c.
3194 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3196 * Fixed minor bug in IDENTIFY command reply sending, which
3197 caused various weird problems during JOIN when it was
3198 resolving names for users. Affected file silcd/command.c.
3200 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3202 * Fixed the IDENTIFY command reply sending to chech better valid
3203 clients. It was possible to send incomplete list of replies.
3204 Affected file silcd/command.c.
3206 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3208 * Added silc_client_command[s]_[un]register functions now to
3209 dynamically register the commands in client library. Removed
3210 the static table of commands. This allows the client library
3211 to call commands without causing the application to know about
3212 what commands library has called.
3214 Removed the INFO command reply kludge to detect when the command
3215 was called by library. Now library use its own command reply
3216 function for INFO command.
3218 Added function silc_client_command_call to call a command.
3219 Application can use it to call command, not access the structure
3222 Now all commands that are sent by the client library (not
3223 explicitly sent by application) use own command reply functions.
3225 Affected files around lib/silcclient/ and in
3226 irssi/src/silc/core/.
3228 * Fixed the WHOIS command reply sending to chech better valid
3229 clients. It was possible to send incomplete list of replies.
3231 Fixed the WHOIS and IDENTIFY to send the request to router
3232 if normal server did not do it and did not find any results.
3234 Affected file silcd/command.c.
3236 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3238 * Moved the internal data from SilcClient context into its
3239 own file, not accesible to application. Affected files
3240 lib/silcclient/client.h and lib/silcclient/client_internal.h,
3241 and other files in client library.
3243 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3245 * Added doc/examples installation target in Makefile.am.pre.
3248 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3250 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
3251 commands the found client entry will be removed from the
3252 cache, after notifying application about the error. Affected
3253 file lib/silcclient/command_reply.c.
3255 * Changed the /MSG to check for exact nickname user gave, and
3256 not let `nick' match `nick@host' if it is only one found. Now,
3257 user must type the exact nickname (like nick@host2) even if
3258 there are no more than one same nicks found. This is to avoid
3259 a possibility of sending nickname to wrong nickname since
3260 `nick' could match `nick@host'. Affected file is
3261 irssi/src/core/silc-servers.c.
3263 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3265 * Do not print "you are now server operator" or similar when
3266 giving /away command. Affected files are
3267 irssi/src/silc/core/client_ops.c, silc-servers.h.
3269 * Made the silc_server_command_pending_error_check to send
3270 the same command reply payload it received back to the
3271 original sender of the command. This way all arguments
3272 that was received by the server will be received by the
3273 client too. Affected file silcd/command.c.
3275 * Added the silc_idcache_add to return the created cache entry
3276 to a pointer. Affected file lib/silccore/silcidcache.[ch].
3278 * Add global clients to expire if they are not on any channel.
3279 This is because normal server will never know if they signoff
3280 if they are not on any channel. The cache expiry will take
3281 case of these entries. This is done by normal servers only.
3282 The affected files are silcd/command_reply.c,
3283 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
3285 * If server receives invalid ID notification for WHOIS or
3286 IDENTIFY and the ID exists in the lists, it is removed.
3287 Affected file silcd/command_reply.c.
3289 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
3290 in client then client entry that it matches is searched and
3291 the nickname is printed on the screen for user. Affected
3292 file irssi/src/silc/core/client_ops.c.
3294 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3296 * Use cache entry expire time in the LIST command reply to
3297 purge old entries from the cache after the LIST command
3298 reply has been received. This way we don't have non-existent
3299 entries in the cache for too long. Affected file is
3300 silcd/command_reply.c.
3302 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3304 * If we are normal server, and we've not resolved client info
3305 in WHOIS or IDENTIFY from router, and it is global client,
3306 we'll check whether it is on some channel. If it is not
3307 then we cannot be sure about its validity and will resolve it
3308 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
3309 file silcd/command.c.
3311 * Search channel by name (if possible) rather than by ID
3312 in IDENTIFY command's command reply. Affected file is
3313 silcd/command_reply.c.
3315 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3317 * Distribute to the channel passphrase in CMODE_CHANGE notify.
3318 Updated specs and implemented it. Affected file silcd/command.c,
3319 silcd/packet_send.c and silcd/packet_receive.c.
3321 * Implemented the <founder auth> payload handling in the JOIN
3322 command. If provided all conditions for channel joining
3323 except requirement to provide correct passphrase can be
3324 overrided by the channel founder. Updated the protocol specs.
3325 Affected file silcd/command.c.
3327 Added support for founder auth in JOIN command in client
3328 library. Fixed the parsing of the JOIN command now to support
3329 all options as they should be. The affected file is
3330 lib/silcclient/command.c.
3332 * Optimized the WHOIS and IDENTIFY commands to send the request
3333 to router only if it includes nicknames or other names. If
3334 they include only IDs then check the local cache first before
3335 routing. Affected file is silcd/command.c.
3337 * Added channels topic announcements. Affected file is
3338 silcd/packet_receive.c and silcd/server.c.
3340 * Fixed the silc_server_send_notify_topic_set to really destine
3341 the packet to channel. Affected file silcd/packet_send.c.
3343 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
3344 library. Affected file lib/silcclient/client_notify.c.
3346 * Added UMODE announcements. Affected file silcd/server.c.
3348 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3350 * Memory leak fixes in:
3352 lib/silcutil/silcsockconn.c
3353 lib/silcske/silcske.c
3354 lib/silcske/groups.c
3356 lib/silccrypt/silcpkcs.c
3357 lib/silccore/silccommand.c
3358 lib/silccore/silcidcache.c
3363 * ROBOdoc documented the lib/silcske/groups.h file and a
3364 bit changed the interface for better.
3366 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3368 * Update the client entry context in the ID cache after
3369 nick change. Affected file lib/silcclient/command.c.
3370 Fixes the CUMODE command when regaining founder privileges,
3371 and a little WHOIS problem.
3373 * Fixed silc_net_gethostbyname to correctly call the
3374 inet_ntop. Affected file lib/silcutil/silcnet.c.
3376 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3378 * Added IPv6 support checking to the configure.in.pre, added
3379 also --enable-ipv6 option to override the check. Affected
3380 file configure.in.pre.
3382 * The silc_thread_create now calls the start function
3383 directly if threads support is not compiled in. Removes
3384 ugly #ifdef's from generic code. Affected files are
3385 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
3387 * Added silc_net_gethostby[name/addr]_async to asynchronously
3388 resolve. Affected files are lib/silcutil/silcnet.[ch].
3390 * Added support for rendering IPv6 based server, client and
3391 channel IDs. Affected file lib/silcutil/silcutil.c.
3393 * Added support for creating IPv6 based server IDs. Affected
3394 file is silcd/serverid.c.
3396 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3398 * Added silc_net_gethostby[addr/name] into the
3399 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
3400 routines. Added silc_net_is_ip[4/6]. Affected file is
3401 lib/silcutil/unix/silcunixnet.c. All routines that take
3402 address as argument now supports both IPv4 and IPv6 addresses.
3404 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3406 * Fixed LIST command reply sending in server. Affected file
3409 * Server now sends the kicker's client ID in the KICK notify
3410 to the kicked client. Affected file silcd/command.c.
3412 * The client library now parses the kickers client ID and
3413 UI displays it. Affected files lib/silcclient/client_notify.c
3414 and irssi/src/silc/core/silc-channels.c, module-formats.c.
3416 * Made all payload parsing function prototypes consistent.
3417 They all take now const unsigned char * and uint32 pair as
3418 the payload data instead of SilcBuffer. Changes all around
3419 the source tree. Other unsigned char* -> const unsigned char*
3420 changes around the tree as well.
3422 * Optimized SFTP client and server packet sending not to
3423 allocate new buffer for each packet but to recycle the
3424 first allocated buffer. Affected files are
3425 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
3427 * Optimized the SFTP client to use SilcList instead of
3428 SilcDList for requests, because it is faster. Affected file
3429 is lib/silcsftp/sftp_client.c.
3431 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
3432 into lib/silccore/silcid.[ch].
3434 Renamed silcpayload.[ch] into silcargument.[ch].
3436 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3438 * If client entry is deleted with active key agreement
3439 session, abort the session.
3441 The silc_client_abort_key_agreement now calls the completion
3442 callback with new SILC_KEY_AGREEMENT_ABORTED status.
3444 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
3447 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3449 * Don't use __restrict in older GCC's. Affected file is
3450 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
3452 * silc_net_localhost now attempts to reverse lookup the
3453 IP/hostname. Affected file lib/silcutil/silcnet.c.
3455 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
3456 command. It can be used to gain founder privileges at
3457 the same time when joining the channel.
3459 Defined that the SILC_NOTIFY_TYPE_KICKED send the
3460 kicker's client ID as well. Updated protocol specs.
3462 Defined that the server must send SILC_COMMAND_IDENTIFY
3463 command reply with error status to client who sent
3464 private message with invalid client ID.
3466 Updated the protocol specification.
3468 * Added silc_server_send_command_reply to send any
3469 command reply. Affected file silcd/packet_send.[ch].
3471 * Added silc_id_payload_encode_data to encode ID payload
3472 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
3474 * The server now send IDENTIFY command reply with error
3475 status if client ID in private message is invalid. Affected
3476 file silcd/packet_receive.c.
3478 * Save the server key file with server's IP address in
3479 the filename instead of hostname. The affected file is
3480 irssi/src/silc/core/client_ops.c.
3482 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3484 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
3487 * Added libtool support for compiling shared objects in
3488 lib/silcsim. Affected file configure.in.pre and
3489 lib/silcsim/Makefile.am. Original patch by cras.
3491 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3493 * Pid file configuration, and server's config file fixes
3494 patch by toma. Updated CREDITS file.
3496 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3498 * Fixed silc_client_channel_message to not try to decrypt
3499 the message twice if it resolved the destination client
3500 information. This could cause of dropping one channel
3501 message. Affected file lib/silcclient/client_channel.c.
3503 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3505 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3506 lib/silcclient/client.c. This function is used when the SILC
3507 Client is run under some other scheduler, or event loop or
3508 main loop. On GUI applications, for example this may be
3509 desired to used to run the client under the GUI application's
3510 main loop. Typically the GUI application would register an
3511 idle task that calls this function multiple times in a second
3512 to quickly process the SILC specific data.
3514 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3516 * Fixed silc_server_drop() for dropping the supplementary
3517 groups as well, this could cause a security hole on some
3520 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3522 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

3533 Affected file irssi/src/silc/core/client_ops.c.
3535 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3537 * Fixed the silc_idcache_list_* routines to really support
3538 the dynamic list. Fixes a crash. Affected file is
3539 lib/silccore/silcidcache.c.
3541 * Fixed the LIST command reply to really call LIST command's
3542 pending callbacks. Affected file silcd/command_reply.c.
3544 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3546 * Update conn->local_entry->nickname after giving NICK
3547 command. Affected file lib/silcclient/command.c.

3551 * Added the [pid] option to the silcd configuration file
3553 Affected files: serverconfig.[ch] and silcd.c
3555 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3557 * Save fingerprint in WHOIS command reply in server.
3558 Affected file silcd/command_reply.c.
3560 * Fixed NICK commands pending callback registration.
3561 Affected file lib/silcclient/command.c.
3563 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3565 * Use ++server->cmd_ident when sending commands in server,
3566 instead of random number. Affected file silcd/command.c.
3568 * Fixed GETKEY command reply to call actually GETKEY pending
3569 command callbacks. Affected file silcd/command_reply.c.
3571 * A bit stricter check for nicknames. Check for same nickname
3572 in NICK command also. Affected file silcd/command.c.
3574 * Do not call INFO command everytime client ID changes, only
3575 during first connecting. Affected file lib/silcclient/client.c.
3577 * Set the new nickname only after successful command reply for
3578 NICK command is returned by server. Affected file
3579 lib/silcclient/command.c.
3581 * Remove nicknames from nicklist during server_signoff notify.
3582 Should fix /NAMES bit more. The affected file is
3583 irssi/src/silc/core/silc-channels.c.
3585 * Added `fingerprint' field to the SilcIDListData in the
3586 silcd/idlist.h to hold the fingerprint of the client's
3589 Send the fingerprint of the client's public key in WHOIS
3592 Affected files silcd/command.c, and silcd/idlist.[ch].
3594 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3595 create fingerprint from given data.
3597 * Show the fingerprint of the client's public key in WHOIS.
3598 Affected files irssi/src/module-formats.[ch] and
3599 irssi/src/silc/core/client_ops.c.
3601 * Format the multiple same nicknames also during JOIN and
3602 NICK_CHANGE notifys. Affected file is
3603 lib/silcclient/client_notify.c.
3605 * Do not print error on screen for invalid private message
3606 payload since it can come if someone is sending private
3607 messages with wrong key. Affected file
3608 lib/silccore/silcprivate.c.
3610 * Fixed multiple concurrent /PING crash. Affected file
3611 lib/silcclient/command.c.
3613 * Changed the wrong ID encoding. All IP addresses must be
3614 in MSB first order in encoded format. They were encoded
3615 wrong and was in LSB format. Affected files are
3616 silcd/serverid.c, lib/silcutil/silcutil.c.
3618 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3620 * Call the `connect' client operation through the scheduler
3621 in case of error. Affected file lib/silcclient/client.c.
3623 * Call the `failure' client operation even if the error
3624 occurred locally during a protocol. Affected file is
3625 lib/silcclient/protocol.c.
3627 * Added support of sending LIST command to router from normal
3628 server. This way normal server can get list of all channels
3629 in the network too. Fixed the channel list sending in the
3630 server too. Affected files are silcd/command.c, and
3631 silcd/command_reply.[ch].
3633 * Added silc_server_update_channels_by_server and
3634 silc_server_remove_channels_by_server. They are used during
3635 disconnection of primary router and in backup router protocol.
3636 Affected file silcd/server_util.[ch], silcd/server.c and
3637 silcd/server_backup.c.
3639 * Fixed channel adding to global list in IDENTIFY command
3640 reply in server. Affected file silcd/command_reply.c.
3642 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3644 * If the incoming packet type is REKEY or REKEY_DONE process
3645 that packet always synchronously. Fixes yet another MAC
3646 failed error on slow (dialup) connections. Affected file
3647 lib/silcclient/client.c and silcd/server.c.
3649 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3651 * Call check_version SKE callback for initiator too. Affected
3652 file lib/silcske/silcske.c.
3654 * Implemented fix for security hole found in the SKE that was
3655 fixed in the specification few days back; the initiator's
3656 public key is now added to the HASH value computation.
3657 Added backwards support for the old way of doing it too, for
3658 old clients and old servers. Affected file is
3659 lib/silcske/silcske.c.
3661 * Enabled mutual authentication by default in SKE. If initiator
3662 is not providing mutual authentication the responder will
3663 force it. This will provide the proof of posession of the
3664 private key for responder. The affected files are
3665 lib/silcclient/protocol.c and silcd/protocol.c.
3667 * Do not cache anymore the server's public key during SKE.
3668 We do mutual authentication so the proof of posession of
3669 private key is done, and if the server is authenticated in
3670 conn auth protocol with public key we must have the public
3671 key already. Affected file silcd/protocol.c.
3673 * Added new global debug variable: silc_debug_hexdump. If
3674 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3675 file lib/silcutil/silclog.[ch].
3677 * Fixed compilation warning due to char * -> const char *.
3678 Affected files lib/silcutil/silcnet.h, and
3679 lib/silccore/silcauth.[ch].
3681 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3683 * Fixed CMODE command when new channel key was created. If
3684 the creation failed the old key was removed. Next time giving
3685 same command would crash the server since the old key was
3686 freed already. Affected file silcd/command.c.
3688 * Fixed the silc_server_announce_get_channels to not crash
3689 on reconnect. Affected file silcd/server.c.
3691 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3693 * Added silc_log_set_debug_string function to set a regex
3694 string to match for debug output. Only the function names,
3695 or filenames matching the given debug string is actually
3696 printed. This way it is possible to filter out those debug
3697 strings that user is not interested in.
3699 Fixed a bug in silc_string_regexify.
3701 Affected files lib/silcutil/silclog.[ch], and
3702 lib/silcutil/unix/silcunixutil.c.
3704 * Changed the -d options in both server and Irssi SILC client
3705 to take the debug string as argument. Affected files
3706 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3708 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3710 * Added silc_hash_babbleprint to create a Bubble Babble
3711 Encoded fingerprint. The encoding is developed by Antti
3712 Huima (draft-huima-babble-01.txt), and it creates human
3713 readable strings out of binary data. Affected file
3714 lib/silccrypt/silchash.[ch].
3716 * Print the babble print now in addition of fingerprint as well
3717 in Irssi SILC client. Affected files are
3718 irssi/src/fe-common/silc/module-formats.[ch],
3719 irssi/src/fe-common/silc/core/client_ops.c.
3721 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3723 * Fixed a security problem found in SKE. The initiator's
3724 public key too is now added to the HASH hash value creation
3725 which is signed by the responder to create the SIGN value.
3726 This will prevent anyone in the middle to lie to the responder
3727 about the initiator's public key. If this is done now, the
3728 man in the middle will get caught. Updated the protocol
3731 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3733 * Better installation directory handling. Configure module
3734 paths and other paths automatically to example_silc* files
3735 in doc/. A patch by toma.
3737 * Fixed compiler warning from MPI library, and from SILC RNG.
3740 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3741 It can be configured with ./configure. A patch by toma.
3743 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3745 * Find correct make to use in prepare-clean. A patch by
3746 toma. Affected file prepare-clean.
3748 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3750 * Added irssi variables use_auto_addr, auto_bind_ip,
3751 auto_bind_port and auto_public_ip.
3753 * Changed the interface for silc_client_send_key_agreement
3754 in lib/silcclient/silcapi.h
3758 irssi/src/silc/core/silc-core.c
3760 lib/silcclient/silcapi.h
3761 irssi/src/silc/core/silc-channels.c
3762 lib/silcclient/client_keyagr.c
3765 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3767 * Added silc_pkcs_public_key_compare to compare two
3768 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3770 * Check that the client who set the founder mode on the
3771 channel is the same client that is giving the founder
3772 mode to itself. It is done by comparing the saved public
3773 key (it is saved even in the authentication is passphrase).
3774 Affected file silcd/command.c.
3776 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3778 * Do not process packet for disconnected socket connection.
3779 Affected file lib/silccore/silcpacket.c.
3781 * Process the DISCONNECT packet through scheduler in the
3782 client library. Affected file lib/silcclient/client.c.
3784 * Fixed the silc_client_packet_parse to not to increase
3785 the packet sequence number if the conn->sock and the
3786 current socket connection is not same. This can happen
3787 for example during key agreement when the conn includes
3788 multiple socket connections (listeners). Affected file
3789 lib/silcclient/client.c.
3791 * The sender of the file transfer request now provides also
3792 the pointer (listener) for the key exchange protocol. If
3793 the listener cannot be created then it sends empty key
3794 agreement and lets the receiver provide the listener.
3796 Added `local_ip' and `local_port' arguments to the
3797 silc_client_file_send. If they are provided they are used,
3798 if not then it will attempt to find local IP address, if
3799 not found or bind fails then the remote client will provide
3802 Affected files are lib/silcclient/client_ftp.c and
3803 lib/silcclient/silcapi.h.
3805 * Extended the FILE SEND command to support defining the
3806 local IP and port for key exchange listener. They are
3807 optional. Affected file irssi/src/silc/core/silc-servers.c.
3809 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3811 * Defined to WHOIS command reply the sending of fingerprint
3812 of the client's public key (if the proof of posession of the
3813 corresponding private key is verified by the server).
3814 Updated to the protocol specification.
3816 * Added support of receiving the client's public key's
3817 fingerprint in command reply in client library. Affected
3818 file is lib/silcclient/command_reply.c, and
3819 lib/silcclient/idlist.[ch].
3821 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3823 * Do not send over 128 chars long nickname to the server
3824 in NICK command. Affected file lib/silcclient/command.c.
3826 * Do not send over 256 chars long channel names to the server
3827 in JOIN command. Affected file lib/silcclient/command.c.
3829 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3831 * Assure that silc_server_close_connection cannot be called
3832 twice for same socket context. Affected file is
3835 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3837 * Send error message to application if opening file for
3838 writing during file transfer fails. Affected file is
3839 lib/silcclient/client_ftp.c.
3841 Remove all file transfer sessions for a client that we're
3842 removing from ID cache.
3844 Affected file is lib/silcclient/client_ftp.c.
3846 * Fixed silc_net_addr2bin to return correct address. Affected
3847 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3849 * Fixed file transfer session removing on signoff notify.
3850 Affected file irssi/src/silc/core/silc-servers.c.
3852 * Added the SilcClientFileError to be returned in the monitor
3853 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3854 Affected file lib/silcclient/silcapi.h.
3856 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3858 * Fixed a crash in silc_client_ftp_free_sessions and
3859 silc_client_ftp_session_free_client. Affected file
3860 lib/silcclient/client_ftp.c.
3862 * Added `disabled' field in the SilcChannelEntry in the server
3863 to indicate if the server entry is disabled. Affected file
3864 silcd/idlist.h, silcd/command[_reply].c.

3867 started. Affected file silcd/silcd.c.
3869 * Added silc_server_packet_send_clients to send a packet to
3870 the provided table of client entries. Affected file
3871 silcd/packet_send.[ch].
3873 * Fixed a crash in client resolving in client_prvmsg.c in
3874 client library. Affected file lib/silcclient/client_prvmsg.c.
3876 * Do not actually remove the client directly from ID cache
3877 during SERVER_SIGNOFF, but invalidate it. This way we
3878 preserve the WHOWAS info for the client. Affected file
3879 silcd/server_util.c.
3881 * Fixed SERVER_SIGNOFF notify handling in the server. The
3882 server is now able to process incoming SERVER_SIGNOFF notify
3883 for a server that it doesn't even know about. It will remove
3884 the clients provided in the notify. Affected file
3885 silcd/packet_receive.c.
3887 * Check for partial packet in data queue after every packet that
3888 was found from the queue. Return and wait for more data if
3889 there is partial data in queue. Affected file is
3890 lib/silccore/silcpacket.c.
3892 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3894 * Added SilcClietFileError enum to indicate error in
3895 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3896 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3897 Affected files lib/silcclient/silcapi.h and
3898 lib/silcclient/client_ftp.c.
3900 * Check that newsize in silc_buffer_realloc is larger than
3901 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3903 * Added better monitor of file transfers. It now monitors
3904 key agreement protocol during the file transfer too. Added
3905 error reporting too. Affected files
3906 irssi/src/silc/core/silc-servers.c,
3907 irssi/src/fe-common/silc/module-formats.[ch].
3909 * Wrote a help file for FILE command.
3911 * Added silc_rng_global_get_byte_fast to get not-so-secure
3912 random data as fast as possible. Random data is read from
3913 /dev/urandom if available and from the SILC RNG if not
3914 available. It is used in padding generation. Affected file
3915 lib/silccrypt/silcrng.[ch].
3917 * All packets in client library are now processed synchronously.
3918 Optimized packet processing a lot. Affected file
3919 lib/silcclient/client.c.
3921 * All server connection packets are processing synchronously
3922 now in server, to optimize packet processing. Affected file
3925 * Include files are installed now only in Toolkit distribution
3926 if make install is given. Affected files: all Makefile.am's.
3928 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3930 * Assure that silc_client_notify_by_server_resolve does not
3931 resolve the client information multiple times. If it cannot
3932 be found by the first it cannot be found at all. Affected
3933 file lib/silcclient/client_notify.c.
3935 * Fixed WHOWAS command reply calling. Affected file
3936 lib/silcclient/command_reply.c.
3938 * Removed all references to silc_idlist_get_client from the
3939 Irssi SILC client since that call is internal call used by
3940 the library. The Irssi SILC client will use now client
3941 retrieval functions found in silcapi.h.
3943 * Fixed a bug in resolving nickname info before sending
3944 private message. It used freed memory. Affected file
3945 irssi/src/silc/core/silc-servers.c.
3947 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3949 * Assure my_channels statistics cannot go negative in server.
3950 Affected files silcd/server.c, silcd/server_util.c.
3952 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3954 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
3956 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

3962 lib/sftp/sftp_fs_memory.c.
3964 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3966 * Added silc_net_localip to return local host's IP address.
3967 Affected file lib/silcutil/silcnet.[ch].
3969 * If key exchange or rekey protocol is active for a connection
3970 parse all packets syncronously since there might be packets
3971 in packet queue that we are not able to process without first
3972 processing packets before them. Affected file silcd/server,
3973 lib/silcclient/client.c.
3975 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3976 whether library should continue processing the packet.
3977 Affected file lib/silccore/silcpacket.h.
3979 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
3980 SilcSFTPMonitorData to SFTP server to monitor various
3981 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

3988 Added preliminary support for simple client to client one-file
3989 transmission. Affected file lib/silcclient/client_ftp.c,
3990 lib/silccilent/client.[ch].
3992 * Added new local command FILE to the Irssi SILC Client.
3993 It is used to perform the file transfer. It has subcommands
3994 SEND, RECEIVE, SHOW and CLOSE. Affected files
3995 irssi/src/silc/core/client_ops.c,
3996 irssi/src/silc/core/silc-server.[ch].
3998 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4000 * Relay the SILC_PACKET_FTP in the server. Affected files
4001 silcd/server.c and silcd/packet_receive.c.
4003 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4005 * Renamed silc_file_read and silc_file_write to functions
4006 silc_file_readfile and silc_file_writefile. Added function
4007 silc_file_open and silc_file_close. Affected files
4008 lib/silcutil/silcutil.[ch].
4010 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4012 * Resolve the client info when received private message or
4013 channel message for a client which nickname we don't know.
4014 Affected files lib/silcclient/client_prvmsg.c and
4015 lib/silcclient/client_channel.c.
4017 * Do not crash in /KEY if client is not connected. Affected
4018 file irssi/src/silc/core/silc-channels.c.
4020 * Added SilcClientStatus field to the SilcClientEntry in the
4021 lib/silcclient/idlist.h.
4023 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
4024 is incomplete and is being resolved, it won't be resolved
4027 Make sure also that USERS command reply does not resolve
4028 twice information. Affected file is
4029 lib/silcclient/command_reply.c.
4031 Make sure that silc_client_get_clients_by_list does not
4032 resolve twice same information.
4034 * Check for valid client->id in the silc_server_free_client_data.
4035 Affected file silcd/server.c.
4037 * Fixed /GETKEY nick@server not to crash if the server entry
4038 is not found. Affected file lib/silcclient/command.c.
4040 * Fixed the silc_server_check_cmode_rights to check the
4041 requested modes correctly. Affected file silcd/command.c.
4043 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4045 * Better checks for non-printable chars in nick added.
4046 Affected file silcd/command.c.
4048 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4050 * Call the silc_server_udpate_servers_by_server in the
4051 primary router that comes back online in the backup resuming
4052 protocol. Otherwise it routes packets wrong. Affected file
4053 silcd/server_util.[ch], silcd/server_backup.c.
4055 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4057 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
4058 lib/silcutil/silcbuffmt.[ch].
4060 * Redefined the SILC packet header to include the padding
4061 length. Affected file lib/silccore/silcpacket.[ch].
4063 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
4064 length for maximum padding up to 128 bytes). Affected
4065 file lib/silccore/silcpacket.h.
4067 * Removed all backwards support for old 0.5.x MAC thingies.
4068 The SILC packet header change makes it impossible to be
4069 backwards compatible.
4071 * Send the ENDING packet with timeout in the backup resuming
4072 protocol. This is to assure that all routers has connected
4073 to the primary router. Affected file silcd/server_backup.c.
4075 * Changed the RNG to take the first IV from random data. It
4076 used to take it from zero actually. Changed the RNG also
4077 to use /dev/urandom during session. /dev/random is used
4078 in initialization. Affected file lib/silccrypt/silcrng.[ch].
4080 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4082 * Changed the SILC packet header to have the first two bytes
4083 (the packet length) encrypted. Affected files aroung the
4084 code tree, lib/silccore/silcpacket.[ch]. Removed the
4085 SilcPacketCheckDecrypt callback. It is not needed anymore
4086 since the silc_packet_receive_process will determine now
4087 whether the packet is normal or special.
4089 * Implemented the unidirectional MAC keys. Affected files
4090 lib/silcske/silcske.c, silcd/protocol.c and
4091 lib/silcclient/protocol.c.
4093 * Implemented the packet sequence number to the MAC computation.
4094 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
4095 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
4096 lib/silcclient/protocol.c.
4098 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4100 * Allow backup router to announce servers. All servers
4101 announced by backup router are added to the global list
4102 automatically. Update hte server's socket to our primary
4103 router also when backup router announces a server.
4104 Affected file silcd/packet_receive.c.
4106 * Do not update the client->router in the function
4107 silc_server_udpate_clients_by_server if the client is on
4108 global list. We might fail to find any specific server
4109 for locally connected clients and local cell clients. They
4110 should still use the `from' and not `to' as client->router.
4111 This fixes backup router resuming protocol. Affected file
4112 silcd/server_util.c.
4114 * Decrease channel statistics count only if the channel
4115 deletion worked. Affected files are silcd/server.c and
4116 silcd/server_util.c.
4118 * Added silc_server_update_servers_by_server to update origin
4119 of all server entries. Used during backup router protocol.
4120 Affected files silcd/server_util.[ch], silcd/server.c. and
4121 silcd/backup_router.c.
4123 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
4124 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
4125 silc_hmac_get_hash and silc_hmac_get_name. Affected file
4126 lib/silccrypt/silchmac.c.
4128 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4130 * Assure that router cannot reroute the same channel message
4131 to the sender. Affected file silcd/packet_receive.c.
4133 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4135 * Made better checks that the channel message is not sent
4136 to the router it came from. Affected file is
4137 silcd/packet_send.c. Fixed memory leak too.
4139 * Announce informations for incoming router connection, but
4140 only after checking if it is replaced by backup router.
4141 Affected file silcd/packet_receive.c.
4143 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4145 * Fixed the backup resuming protocol to work in multiple
4146 router environment. Affected file silcd/server_backup.c.
4148 * Route packet only to one router in the function
4149 silc_server_packet_send_to_channel. Affected file is
4150 silcd/packet_send.c.
4152 * Fixed silc_server_send_notify_dest to set the broadcast
4153 flag. Fixed the silc_server_send_notify_topic to actually
4154 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
4155 Affected file silcd/packet_send.c.
4157 * Changed the SFTP Filesystem interface. Changed the
4158 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
4159 the filesystem operation function. The SilcSFTPFilesystem
4160 is now a context that is allocated by all filesystem allocation
4161 functions and it already includes the operations structure
4162 and filesystem specific context. It is given as argument
4163 now to the silc_sftp_server_start. This made the interface
4164 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
4165 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
4167 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4169 * Changed the backup router adding and getting interfaces
4170 in the server. The router that will be replaced by the
4171 specified backup router is now sent as argument. Affected
4172 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
4175 * Added silc_net_addr2bin_ne to return the binary form of
4176 the IP address in network byte order. Affected files
4177 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
4179 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4181 * Check for existing server ID in silc_server_new_server
4182 and in silc_server_connect_to_router_final and remove the
4183 old entry if it exists. Affected file silcd/packet_receive.c,
4186 * Send the channel message always to only one router, either
4187 in upstream or downstream. Affected file is
4188 silcd/packet_send.c.
4190 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4192 * Wrote the definition of the backup resuming protocol to the
4193 protocol specification.
4195 * Removed one redundant channel key generation from normal
4196 server during joining procedure. Removed one redundant
4197 channel key sending from server to router during joining
4198 procedure. Affected file silcd/command.c.
4200 * Made minor bugfixes to the backup router resuming protocol.
4201 Affected file silcd/server_backup.c, server.c.
4203 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4205 * Added --disable-asm configuration option. Affected files
4206 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
4209 * Implemented the backup resuming protocol that is used to
4210 resume the primary router position in the cell after the
4211 primary router comes back online. Affected files
4212 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
4213 and silcd/server_util.[ch].
4215 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4217 * Sleep two (2) seconds after sending QUIT command to server.
4218 Affected file lib/silcclient/command.c.
4220 * Assure that if outgoing data buffer is pending do not force
4221 send any data. Affected file silcd/packet_send.c.
4223 * Assure that if outgoing data buffer is pending do not force
4224 send any data. Affected file lib/silcclient/client.c.
4226 * Implemented the backup router support when the primary router
4227 goes down. The servers and routers can now use the backup
4228 router as new primary router without loosing connectivity.
4230 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4232 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
4233 in the server to indicate disabled entry. All data read
4234 from the connection will be ignored and no data is sent
4235 for entry that is disabled. Affected files are
4236 silcd/idlist.h, silcd/server.c.
4238 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4240 * Created SFTP client and server test programs in the
4241 lib/silcsftp/tests directory.
4243 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4245 * Implemented memory filesystem (virtual filesystem) for
4246 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
4249 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4251 * Implemented the SFTP (SSH File Transfer Protocol) to the
4252 lib/silcsftp. It includes SFTP client and SFTP server
4255 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4257 * Moved lib/silccore/silcprotocol.[ch] to the
4258 lib/silcutil library.
4260 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
4261 take variable argument list pointer as argument. Affected
4262 file lib/silcutil/silcbuffmt.[ch].
4264 * Added silc_buffer_set function that is used to set data
4265 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
4266 Affected file lib/silcutil/silcbuffer.h.
4268 * Changed various routines in the core library to use the new
4269 silc_buffer_set instead of allocating new buffer only for
4272 * Added 64-bit value formatting and unformatting support to the
4273 silc_buffer_[un]format routines. Affected file is
4274 lib/silcutil/silcbuffmt.[ch].
4276 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
4277 to includes/bitmove.h.
4279 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4281 * Fixed channel user mode saving in client library. Affected
4282 file lib/silcclient/command[_reply].c.
4284 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4286 * Defined the file transfer to the SILC Protocol. Added
4287 new packet type SILC_PACKET_FTP and defined File Transfer
4288 Payload. The mandatory file transfer protocol is SFTP
4289 (SSH File Transfer Protocol). Affected file in addition
4290 of the internet draft is lib/silccore/silcpacket.h.
4292 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
4293 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
4294 is used as part of backup router protocol when the primary
4295 router of the cell is back online and wishes to resume
4296 the position as primary router.
4298 * Redefined the MAC generation keys in the protocol. The
4299 same key is not used anymore in both direction. Both
4300 direction will now use different keys for sending and
4301 receiving. This fixes a potential security flaw. This
4302 change causes incompatibilities in the protocol.
4304 * Redefined also the MAC computation from the packet.
4305 An packet sequence number is now added to the MAC
4306 computation. This prevents possible replay attacks against
4307 the protocol. This change too causes incompatibilities
4310 Added `sequence' field to the SilcPacketContext to hold
4311 the current sequence number for the packet.
4313 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4315 * Added `created' field to the SilcIDListData in the file
4316 silcd/idlist.h to indicate the time when the entry was
4319 * Added `created' field to the SilcChannelEntry too. Affected
4320 file silcd/idlist.h.
4322 * Added `creation_time' aguments to all the announcement functions
4323 in the server. If it is provided then only the entries that
4324 was created after the provided time frame are actually
4325 announced. Affected file silcd/server.[ch].
4327 * The protocol says that the Channel ID's IP address must be
4328 based on the router's IP address. Added check for this in
4329 the silc_server_new_channel when processing incoming New Channel
4330 Payload. Affected file silcd/packet_receive.c.
4332 * Print out the correct version with --version in SILC client.
4333 Affected file irssi/src/silc/core/silc-core.c.
4335 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4337 * Fixed WHOWAS command to check for completnes of the client
4338 entry always, not just when the command is coming from client.
4339 Affected file silcd/command.c.
4341 * Added new function silc_server_packet_queue_purge to purge the
4342 outgoing data queue to the network. After the function returns
4343 it is guaranteed that the outgoing packet queue is empty.
4344 Affected file silcd/packet_send.[ch].
4346 * Purge the outgoing packet queue in the rekey protocol's final
4347 callback to assure that all rekey packets go to the network
4348 before quitting the protocol. Affected file silcd/server.c.
4350 * Added silc_client_packet_queue_parse as similar function as
4351 in server to the client library. The affected file is
4352 lib/silcclient/client.c.
4354 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4356 * Splitted silcd/server.c and created silcd/server_util.[ch]
4357 for utility functions.
4359 * Added new socket flag SILC_SF_DISABLED to indicate that the
4360 connection is open but nothing can be sent to or received from
4361 the connection. Affected file lib/silcutil/silsockconn.[ch].
4362 The checking for disabled socket is checked in the low level
4363 silc_socket_write and silc_socket_read functions.
4365 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4367 * Allow only nicknames and channel names that fits into the
4368 7-bit unsigned char ASCII set. Affected file silcd/command.c.
4370 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4372 * When processing JOIN command reply in server check that if
4373 the channel exists in our global list we'll move it the local
4374 list. Affected file silcd/command_reply.c.
4376 * Fixed the check whether client is joined on the channel already
4377 in JOIN command. Affected file lib/silcclient/command.c.
4379 * Fixed the JOIN command reply to check whether the channel
4380 already exists. Affected file lib/silcclient/command_reply.c.
4382 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4384 * Added silc_ske_status_string to map the SKE error numbers
4385 to readable strings. The affected files are
4386 lib/silcske/silcske[_status].[ch].
4388 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4390 * Do not show the private channels on the WHOIS channel list
4391 as it is not allowed by the protocol. The affected file is
4394 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4396 * Assure that the packet length digged from the actual packet
4397 is something sensible in the silc_packet_decrypt_rest_special
4398 in lib/silccrypt/silcpacket.c.
4400 * Free and NULL the allocated pointer in silc_hmac_alloc if
4401 the HMAC allocation fails. The affected file is
4402 lib/silccrypt/silchmac.c.
4404 * Print the selected security properties to the log files in
4405 the server. Affected file silcd/protocol.c.
4407 * Add SKE's reference counter even if calling the completion
4408 callback manually. Otherwise it goes negative, although it
4409 does not cause any problems. The affected file is
4410 lib/silcske/silcske.c.
4412 * Remove the client entry with short timeout after giving the
4413 KILL command. Affected file lib/silcclient/command.c.
4415 * Fixed to send error reply in WHOIS and IDENTIFY commands in
4416 case all found clients are already disconnected (WHOWAS would
4417 found them) in the server. Affected file silcd/command.c.
4419 * Update the last_receive (time of last data received) to be
4420 updated only when received private or channel message so that
4421 the idle time showed in WHOIS makes more sense.
4423 * Added boolean field `valid' in to the SilcClientEntry in the
4424 client library to indicate whether the entry is valid or not.
4425 This fixes the nickname change bug on channel when changing
4426 the nickname to be same than the old (like nick to Nick) the
4427 nickname formatter doesn't set the new nick anymore to Nick@host.
4428 Affected file lib/silcclient/idlist.[ch].
4430 * Now actually fixed the nickname changing on disconnection.
4431 Added new function silc_change_nick to the Irssi SILC Client.
4432 Affected file irssi/src/silc/core/client_ops.c,
4433 irssi/src/silc/core/silc-nicklist.[ch].
4435 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4437 * Check that the public key exists in the GETKEY command before
4438 trying to encode it. Affected file silcd/command.c.
4440 * Print some notifications on received public keys with GETKEY
4441 command in the Irssi SILC Client. Affected files are
4442 irssi/src/fe-common/silc/module-formats.[ch],
4443 irssi/src/silc/core/client_ops.c.
4445 * Use IDENTIFY command to resolve the server information in the
4446 GETKEY command instead of INFO command. Affected file
4447 lib/silcclient/command.c.
4449 * All command reply functions in the client library now calls
4450 the pending command reply callbacks even if an error has
4451 occurred. The server has done this a long time and now it was
4452 time to move the client library to this as well. Now all
4453 errors can be delivered back to the pending command reply
4454 callbacks if necessary. Affected files are
4455 lib/silcclient/command[_reply].[ch].
4457 * Change the nickname on disconnection back to the username
4458 because in reconnect the server will enforce it to it anyway.
4459 Affected file irssi/src/silc/core/silc-servers.c.
4461 * Fixed a config file parsing bug in the Irssi SILC client.
4462 Affected file irssi/src/silc/core/clientconfig.c.
4464 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4466 * When printing the channel mode on JOIN, verify that the
4467 channel key and channel's HMAC are valid. Affected file
4468 irssi/src/silc/core/client_ops.c.
4470 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4472 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
4473 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
4474 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
4476 * Removed channel key rekey task deleting from the function
4477 silc_server_save_channel_key. Affected file silcd/server.c.
4478 Added explicit timeout task context instead that is used to
4479 delete the task if we are registering a new task before the
4480 new task has elapsed.
4482 * When channel key rekey occurs the client library now saves
4483 the old channel key for a short period of time (10 seconds) and
4484 is able to use it in case some is still sending channel
4485 messages encrypted with the old key after the rekey. Affected
4486 file lib/silcclient/[idlist.h|client_channel.c].
4488 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4490 * Added check to the silc_server_new_id_real to not accept
4491 new ID if it is the sender's own ID. Affected file is
4492 silcd/packet_receive.c.
4494 * Assure that we do not announce ourself or the one we've
4495 sending our announcements when we're router and are announcing
4496 servers to our primary router. Affected file silcd/server.c.
4498 * Fixed silc_server_command_identify_check_client to assemble
4499 correct WHOIS packet. It send corrupted WHOIS packet and
4500 caused problem with router to router connections. Affected
4501 file silcd/command.c.
4503 Fixed also silc_server_command_whois_check the same way
4504 as for the IDENTIFY command.
4506 * Added new SilcIDListStatus to the server in the SilcIDListData
4507 structure. The status now includes the current status of
4508 the entry (like registered, resolved etc.). Affected file
4509 silcd/idlist.[ch]. Defined a bunch of different status types
4510 as well. This replaced the old boolean registered field as well.
4512 Added resolve_cmd_ident field to the SilcClientEntry structure
4513 too so that if the entry is for example being resolved so
4514 another command may attach to the same pending command reply
4515 without requiring to resolve the same entry again. This concept
4516 should optimize the WHOIS and the IDENTIFY resolving under
4517 heavy load by taking away unnecessary resolving for entries
4518 that are being resolved already.
4520 Added support for adding multiple pending commands for one
4521 command idenfier. Affected file silcd/command[_reply].[ch].
4523 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4524 before deleting the data. Otherwise the hash table will have
4525 freed data in comparison functions. Affected file is
4526 silcd/command_reply.c.
4528 * Fixed silc_idlist_replace_client_id to add the new entry to
4529 the cache with NULL nickname. Otherwise there will be invalid
4530 memory as the nickname after the nickname is freed. Affected
4531 file silcd/packet_receive.c.
4533 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4534 saved into wrong slots because the previous number of entries
4535 was not taken into account. Affected file silcd/idlist.c.
4536 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4538 * If we are router and we receive JOIN notify to a channel that
4539 does not have any users then notified client is marked as the
4540 channel founder, as it is it. The affected file is
4541 silcd/packet_receive.c
4543 * Added to the extended hash table API's table_del_*ext functions
4544 the destructor as argument too, so that the caller can decide
4545 which destructor to use or whether to use destructor at all.
4546 Affected file lib/silcutil/silchashtable.[ch].
4548 * Fixed ID Cache purging. It actually deleted the entries from
4549 the hash table after the data was freed. The hash table ended
4550 up comparing freed memory. The affected file is
4551 lib/silccore/silcidcache.c.
4553 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4555 * Fixed Irssi SILC client's KILL command's HELP syntax.
4557 * The USERS command now resolves the detailed user information
4558 if the userinfo field is missing. Affected file is
4559 lib/silcclient/command_reply.c.
4561 * Do not print error in silc_file_read if the read file does
4562 not exist. Just silently return NULL. Affected file is
4563 lib/silcutil/silcutil.c.
4565 * Fixed the silc_log_output to not wine about NULL filename
4566 and to not create some bogus " " filename. Affected file is
4567 lib/silcutil/silclog.c.
4569 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4571 * Fixed various printing bugs on the user interface in the
4572 Irssi SILC Client. Minor changes that were forgotten from
4575 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4577 * Fixed the configure.in.pre and the compilation and distribution
4578 environment to support the new autoconf 2.52. That version is
4579 now required to compile the CVS trunk.
4581 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4583 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4584 to generally parse user@fqdn format strings. Affected file
4585 lib/silcutil/silcutil.c.
4587 * Added nickname_format and nickname_force_format fields to the
4588 SilcClientParams structure. The first one defines the format
4589 for the nicknames that the library will enforce if the receives
4590 multiple same nicknames. The second one is boolean value and
4591 can be used to force the library to always enforce the format
4592 to the nicknames regardles whether there are multiple nicknames
4593 or not. This configurable formatting was employed to flexibly
4594 support accessing multiple nicknames from the user interface.
4595 The userinterface can now set the nicknames to what ever format
4596 they prefer. Affected file lib/silcclient/silcapi.h.
4598 Added function silc_client_nickname_format to the file
4599 lib/silcclient/idlist.c. It performs the nickname formatting.
4601 Added new field `hostname´ to the SilcClientEntry context.
4602 It holds the hostname of the client. Affected file is
4603 lib/silcclient/idlist.h.
4605 * Irssi SILC Client sets the nicknames in nick@hostn format.
4606 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4607 irssi/src/silc/core/silc-core.c.
4609 The WHOIS printing now also shows both the real nickname and
4610 the formatted nickname so that user knows how to access the
4611 user if there are multiple same nicknames cached. Affected
4612 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4613 printing formatting too to take the hostname now as a separate
4614 argument. The Affected file is
4615 irssi/src/fe-common/silc/modules-formats.[ch].
4617 * Changed the silc_client_get_clients_local to accept the formatted
4618 nickname as argument. It accepts the real nickname too but the
4619 formatted nickname can be used to find the true entry from
4620 multiple entries. Affected file lib/silcclient/silcapi.h and
4621 lib/silcclient/idlist.c.
4623 * Added nickname_format_parse field to the SilcClientParams.
4624 It is a callback function provided by the application to parse
4625 the nickname out of the formatted nickname string. The library
4626 calls it to get the nickname from the formatted string. Since
4627 the application generally knows better the format of the nickname
4628 string it parses it instead of the library, even though library
4629 encodes the formatted string. If the callback function is not
4630 provided then the library will use the string as is. The
4631 affected file is lib/silcclient/silcapi.h.
4633 * All the nickname strings passed to the client library in
4634 commands are now expected to be formatted nickname strings.
4635 If the command does not support the formatted nickname string
4636 it will assume that the sent string is the actual nickname.
4637 Affected file lib/silcclient/command.c.
4639 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4641 * Added public key authentication support to OPER and SILCOPER
4642 commands in the client library. Affected file is
4643 lib/silcclient/command.c.
4645 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4647 * Changed the get_auth_methdod client operation to be asynchronous.
4648 It can be async if the application resolves the authentication
4649 method from the server during the negotiation. Added new
4650 SilcGetAuthMeth completion callback that the application will
4651 call after resolving the authentication method.
4653 Added function silc_client_request_authentication_method that
4654 the application can use to resolve the authentication method
4655 from the server. Added also SilcConnectionAuthRequest callback
4656 that the library will call after the server has replied. The
4657 application can call this function if it does not know the
4658 current authentication method.
4660 Affected files are lib/silcclient/client.c and
4661 lib/silcclient/silcapi.h.
4663 * The Irssi SILC client now automatically resolves the authentication
4664 method incase any configuration information is not present (and
4665 currently there never is). The affected file is
4666 irssi/src/silc/core/client_ops.c.
4668 * Fixed public key authentication from the client library.
4669 Affected file lib/silcclient/protocol.c. Changed also the
4670 protocol specification about the public key authentication in
4671 the connection authentication protocol. The actual data to be
4672 signed is now computed with a hash function before signing.
4674 * Fixed the public key authentication from the server as well.
4675 Affected file silcd/protocol.c.
4677 * Removed the mlock()'s from the memory allocation routines.
4678 Affected file lib/silcutil/silcmemory.c. The ./configure does
4679 not check anymore for the mlock(). Affected file is
4682 * Fixed USERS command in server to allow the execution of the
4683 command for private and secret channels if the client sending
4684 the command is on the channel. Affected file silcd/command.c.
4686 * Fixed silc_client_get_clients_local to return the clients
4687 count correctly. It could return wrong value. Affected file
4688 lib/silcclient/idlist.c.
4690 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4692 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4693 types. The assembler optimizations seemed not to like 64-bit
4694 data types. The assmebler optimizations thus are now enabled
4695 also for BSD systems as opposed to only enable them for Linux.
4697 * Do not check for threads at all on BSD systems. Affected
4698 file configure.in.pre.
4700 * Removed -n and -h options from the Irssi SILC Client since
4701 they are not used in silc.
4703 * Fixed the prime generation to assure that the first digit
4704 of the generated random number is not zero since our conversion
4705 routines does not like number strings that starts with zero
4706 digit. If zero digit is seen the random number is regenerated.
4707 This caused some corrupted RSA keys when the zero first digit
4708 was met. Affected file lib/silcmath/silcprimegen.c.
4710 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4712 * Fixed WIN32 configuration in the ./configure script.
4713 Fixed to include xti.h on environments that has it.
4714 Patches by Carsten Ilchmann and andrew.
4716 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4718 * Changed the silc_id_create_client_id to be collision
4719 resistant. It is now assured that there cannot be created
4720 two same client ID's. I suspect that some weird bugs in
4721 the server were actually caused by duplicate Client IDs.
4722 Affected file silcd/serverid.[ch]. A router receiving
4723 new ID now also assures and informs the sending server
4724 if the ID caused collision.
4726 * Changed the silc_id_create_channel_id to also assure that
4727 there are no collisions.
4729 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4731 * Statement about ignoring the Mutual Authentication flag when
4732 performing rekey with PFS was a bit misleading. It is ignored
4733 if it was set in the initial negotiation, it cannot be even
4734 set in the rekey. Fixed in the ke-auth draft. Started the
4735 new versions of the protocol drafts in the doc/.
4737 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4739 * Fixed a bug in silc_client_command_identify_save when saving
4740 new channel information. The channel name was no duplicated
4741 and caused crash on exit. Affected file is
4742 lib/silcclient/command_reply.c.
4744 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4746 * Fixed the getkey command handling in the server. Send just
4747 empty OK reply to the sender if the key could not be fetched
4748 (but everything else was ok, like the key just was not available).
4749 Changed the public key parameter to optional in the protocol
4750 specs so that empty OK reply can be sent. Affected file
4753 Added a message to Irssi SILC client to tell to user if the
4754 server did not return a public key.
4756 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4758 * Fixed a channel key regeneration bug. It registered new
4759 timeout tasks exponentially until all system resources were
4760 used. Affected file silcd/server.c.
4762 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4764 * Added the SILC Document generator to the scripts/silcdoc.
4765 It can be used to generate the Toolkit Reference Manual out
4766 of the source tree. Internally it will also use the RoboDoc
4767 generator now imported in util/robodoc.
4769 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4771 * Added couple of return's in rekey protocol if error orccurred
4772 during the protocol. The execution must be terminated.
4773 Affected file silcd/protocol.c. Also, terminate the protocol
4774 always with timeout.
4776 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4778 * The client's Client ID was created initally from the wrong
4779 nickname (it could have been in format nick@host) in the
4780 silc_server_new_client. Affected file silcd/packet_receive.c
4782 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4784 * Added some SILC_LOG_ERROR's to various error conditions
4785 if client could not be added to ID cache. Affected files
4786 silcd/packet_receive.c and silcd/server.c.
4788 * When client's sock->user_data is freed, NULL also the
4789 client->router and client->connection pointers. Added check
4790 for these pointers being NULL to various places around the
4791 code. Affected file silcd/server.c.
4793 * Added client->data.registered == TRUE checks to various
4794 places around the code to assure that unregistered client's
4795 are not handled when it is not allowed. Affected file
4798 * Added `bool registered' fields to all
4799 silc_idlist_[server|client]_get_* routines to indicate whether
4800 the fetched client needs to be registered or not. Affected
4801 file silcd/idlist.[ch].
4803 * Add your own entry as registered to the ID cache in the
4804 server. Affected file server.c.
4806 * Fixed a bug in silc_server_new_server. The SilcServer was
4807 set as the new server's context instead of SilcServerEntry.
4808 This naturally caused some weird bugs.
4810 * Added "updated" field the SilcChannelEntry which indicates
4811 the time since the channel entry was last accessed. This
4812 can be used to determine whether it is necessary to
4813 announce the channel after backup resuming protocol.
4814 Affected files silcd/idlist.[ch].
4816 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4818 * Do not delete the channel rekey task when adding it
4819 for in silc_server_create_channel_key.
4821 * Changed the silc_server_create_channel_key to return
4822 TRUE or FALSE to indicate the success of the channel key
4825 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4827 * Fixed MSVC++ project files and added missing files to
4828 Makefiles under win32/.
4830 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4832 * Do not add TCP_NODELAY flag if the operating system
4833 does not have it defined. Affected files are
4834 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4836 * Fixed buffer overflow from Irssi SILC Client. Affected
4837 file irssi/src/fe-common/core/themes.c.
4839 * Fixed double free in client library in the file
4840 lib/silcclient/client.c when disconnecting from server.
4842 * Applied double free patch from cras to Irssi SILC client.
4843 Affected files irssi/src/core/[modules/expandos].c
4845 * Fixed the disconnection handling to Irssi SILC Client.
4846 The application must call silc_client_close_connection
4847 in ops->connect client operation in case of failure of
4848 the connection. Affected file is
4849 irssi/src/silc/core/client_ops.c.
4851 * Do not set sock->protocol to NULL in the function
4852 silc_client_close_connection after executing the protocol's
4853 final callback since the sock might not be valid anymore.
4854 Affected file lib/silcclient/client.c.
4856 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4858 * Do not enable SILC_THREADS if the linking with libpthread
4859 did not happen. Affected file configure.in.pre.
4861 * Added notion to protocol specification that server must
4862 verify the sent authentication payload with CMODE when
4863 setting the channel founder key. Implemented it to the
4864 server. Affected file silcd/command.c.
4866 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4868 * Added _EXTRA_DIST SILC distribution variable to the
4869 distributions file. It is used to conditionally add extra
4870 files or directories to the specific distribution. Affected
4871 files ./prepare, Makefile.am.pre and distributions.
4873 Removed the `_' from the start of the distribution names.
4876 * Added README.WIN32 for instructions to compile the Toolkit
4879 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4881 * Fixed a double free in disconnection in the server. Affected
4882 file is silcd/server.c.
4884 * Fixed the lib/silcske/groups.c to work now also with GMP
4885 MP library. The string conversion did not work when using
4886 specific base and the base is indicated in the string as well.
4888 * Created win32/ directory which now includes MSVC++ specific
4889 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4890 It will appear only in the toolkit distribution
4892 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4894 * Changed the key material distribution function in case when
4895 the hash output is too short. The data is now concatenated
4896 a bit differently than it used to. Made the change to the
4897 SKE protocol specification.
4899 * Added better GMP detection to configure.in.pre. A patch
4902 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4904 * Fixed a minor bug in SKE that might cause some problem on
4905 some platforms. Affected file lib/silcske/silcske.c.
4907 * Added the cookie checking for initiator in the SKE. It checks
4908 that the responder returns the sent cookie unmodified. The
4909 affected file is lib/silcske/silcske.c. Added new SKE
4910 error type INVALID_COOKIE that can be sent during the
4911 negotiation. Fixed some memory leaks as well.
4913 * Added the "invalid cookie" error message to Irssi SILC client's
4916 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4918 * Added `task_max' field to the SilcClientParams to indicate
4919 the maximum tasks the scheduler can handle. If set to zero,
4920 default values are used. Affected file lib/silcclient/silcapi.h.
4922 * Fixed memory leaks in silc_client_close_connection. Affected
4923 file lib/silcclient/client.c.
4925 * Added silc_client_del_client_entry to client library to free
4926 all memory of given client entry. Affected file is
4927 lib/silcclient/idlist.[ch].
4929 * Added new functions silc_client_del_channel and
4930 silc_client_del_server to delete channel and server entries.
4931 Affected file lib/silcclient/[silcapi.h/idlist.c].
4933 * Removed silc_client_del_client_by_id from silcapi.h.
4935 * Fixed the INFO command to return the server's own info
4936 correctly when querying by Server ID. Affected file is
4939 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4941 * Removed the non-blocking settings in WIN32 code in the
4942 silc_sock_[read/write] and added SleepEx instead. Affected
4943 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4944 of input data is now checked with FIONREAD and ioctlsocket.
4946 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4948 * Call silc_schedule_task_del_by_context in the
4949 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4950 Affected file lib/silccore/silcprotocol.c.
4952 * Call silc_protocol_cancel for active protocols in the
4953 silc_server_close_connection if the funtion
4954 silc_server_free_sock_user_data has not been called.
4955 Affected file silcd/server.c.
4957 * Generic tasks cannot be deleted using the del_by_fd
4958 task deleting function since generic tasks does not match
4959 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4961 * Added a notion to SILCOPER help file that the SILCOPER works
4962 only on router server, not on normal server.
4964 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4966 * Added for WIN32 support for the new scheduler as well.
4967 Affected file lib/silcutil/win32/silcwin32schedule.c.
4969 * Fixed the SHA1 implementation to work on various platforms.
4971 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4973 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4974 API. It is part of the scheduler now. Everything else is
4975 as previously but some functions has changed their names.
4976 Checkout the lib/silcutil/silcschedule.h for the interface.
4977 Updated all applications to use the new interface. Affected
4978 files are lib/silcutil/silcschedule.[ch].
4980 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4982 * Found a bug in the SKE implementation. The HASH value,
4983 specified by the protocol, was not computed correctly. The
4984 public key of the responder was not added to the computation
4985 even though it is mandatory. Affected file lib/silcske/silcske.c.
4986 This unfortunately causes incompatibilities with older
4987 clients and servers.
4989 * Added WIN32 specific network init and uninit functions:
4990 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4991 the Winsock2. Affected file lib/silcutil/silcnet.h and
4992 lib/silcutil/win32/silcwin32net.c.
4994 * Set the socket always to nonblocking mode on WIN32 after
4995 reading data or writing data. Affected file is
4996 lib/silcutil/win32/silcwin32sockconn.c.
4998 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5000 * Fixed various compilation problems under WIN32. Affected
5001 files lib/silcutil/win32/silcwin32thread.c and
5002 lib/silcutil/win32/silcwin32schedule.c.
5004 * Removed all _internal.h #includes from public header
5005 files. Internal headers must never be included from
5008 Removed also the lib/silcske/payload_internal.h file.
5010 * All include files that may be needed (public and some others
5011 included by the public headers) by application developers are
5012 now copied to the ./includes directory. It does not copy any
5013 internal headers. Affected file Makefile.defines.pre and all
5014 Makefile.am's under lib/ and subdirs.
5016 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5018 * Do not change the ~/.silc directory's permissions automatically.
5019 Affected file irssi/src/silc/core/clientutil.c.
5021 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5023 * Do not cancel the protocol in silc_server_close_connection
5024 it might cause recursion. Now cancelled in the function
5025 silc_server_free_sock_user_data. Affected file silcd/server.c.
5027 * Fixed the silc_server_remove_clients_by_server to regenerate
5028 the channel keys correctly finally. Added also new function
5029 silc_server_remove_clients_channels to actually do it.
5030 Affected file silcd/server.c.
5032 * Fixed the silc_server_new_channel to not crash by giving
5033 wrong router to the new channel. Affected file is
5034 silcd/packet_receive.c.
5036 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5038 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
5039 which is given as argument to the silc_client_alloc now.
5040 It can be used to configure the client and set various parameters
5041 that affect the function of the client.
5043 * The USERS command in server did not check whether the channel
5044 is private or secret. Affected file silcd/command.c.
5046 * Added new argument to the USERS command in protocol specification.
5047 The USERS command now can take the channel name as argument
5048 as well. Added support for this in client and server and
5049 updated the protocol specs.
5051 * Completed the GETKEY command in client. It can be now used
5052 to fetch also servers public key not only some clients.
5053 Affected files lib/silcclient/command[_reply].c.
5055 * Added silc_client_get_server to return server entry by the
5056 server name. Affected files lib/silcclient/silcapi.h and
5059 * Redefined the IDENTIFY command in protocol specification to be
5060 more generic. It now can be used to query information about
5061 any entity in the SILC Network, including clients, servers and
5062 channels. The query may be based either the entity's name
5063 or the ID. Added support for this in both client and server.
5065 Affected files silcd/command.c and lib/silcclient/command.c
5066 and command_reply.c.
5068 * Optimized the WHOIS and WHOWAS commands in the server. Removed
5069 the _from_client and _from_server functions. Affected file
5072 * Added silc_client_get_channel_by_id_resolve to the file
5073 lib/silcclient/silcapi.h to resolve channel information by
5074 its ID. Added also silc_client_get_channel_by_id that
5075 does not resolve it from the server.
5077 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5079 * Added SilcServerEntry context into the client library
5080 to represent one server. The INFO command now allocates
5081 these to save the resolved server info. For now on the
5082 client library will also keep information about servers,
5083 connected and resolved with INFO.
5085 The INFO command now allocates the SilcServerEntry context
5086 and saves the server info there. The COMMAND_REPLY in
5087 the INFO now returns the parameters to application in
5088 same order as defined in the protocol specification.
5090 The entries are cached in the client->server_cache.
5092 * The INFO command is now issued after received the Client ID
5093 from the server. Affected file lib/silcclient/client.c.
5095 * The CMODE_CHANGE notify may now return also an SilcServerEntry
5096 to the application as the mode changer might be server.
5097 It is guaranteed that NULL is not returned anymore to the
5098 application. Affected file lib/silcclient/client_notify.c.
5100 The ID Type is now also passed to the application so that
5101 it can check whether the returned entry is SilcClientEntry
5104 Added new function silc_client_get_server_by_id to return
5105 the server entry by ID. Affected files are the
5106 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
5108 * Do not create the channel in the Irssi SILC Client when issuing
5109 the JOIN command but when received the sucessful JOIN command
5110 reply. Otherwise the channel might get created even though we
5111 could not join it. The Affected file is
5112 irssi/src/silc/core/[silc-channels.c/client_ops.c].
5114 * Fixed a channel joining bug in router. The router must also
5115 check the channel modes, invite and ban lists etc. when serving
5116 the JOIN command sent by normal server. Affected file is
5117 silcd/command.c. The router now resolves the client's
5118 information from the server who sent the JOIN command if it
5119 does not know it, and processes the JOIN command only after
5122 * Changed the SilcCommandCb to take new argument; void *context2.
5123 Affected file lib/silccore/silccommand.h
5125 The second argument in the command callbacks in the server now
5126 includes the SilcServerCommandReplyContext if the command was
5127 called as pending command callback from the command reply.
5128 Otherwise it is NULL. When called as pending the status of the
5129 command reply will be checked and if it was erronous the
5130 error will be sent to the original sender of the command.
5131 This way the client always receives the error messages even
5132 though the server was actually the one who received the error
5133 when it resent the command to router, for example. Affected
5134 files silcd/command[_reply].[ch].
5136 * Fixed sending WHOWAS command's error message to client if
5137 the requested client could not be found. It was missing.
5140 * Changed the CMODE and CUMODE commands reply arguments in the
5141 protocol specification. The Channel ID is now sent in both
5142 of the commands to identify the channel. Implemented this
5143 new feature to the client and server. Affected files
5144 lib/silcclient/command_reply.c and silcd/command.c.
5146 * Made better checks for invite and ban lists in the JOIN
5147 command in server. Affected file silcd/command.c.
5149 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5151 * The server now performs the incoming host IP/DNS lookup
5152 using the silc_socket_host_lookup and thus does not block
5153 the server anymore. Affected file silcd/server.c.
5155 * Completed the multi-thread support for SILC Scheduler in
5156 the lib/silcutil/silcschedule.c.
5158 * Fixed the configure.in.pre to detect the pthread correctly
5161 * Fixed a deadlock in silc_task_queue_wakeup in the file
5162 lib/silcutil/silctask.c.
5164 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5166 * Added new function silc_schedule_wakeup that is used in
5167 multi-threaded environment to wakeup the main thread's
5168 schduler. It needs to be used when a thread adds a new task
5169 or removes a task from task queues. After waking up, the
5170 scheduler will detect the task queue changes. If threads
5171 support is not compiled in this function has no effect.
5172 Implemented the wakeup mechanism to both Unix and WIN32
5173 systems. Affected files are lib/silcutil/silcschedule.[ch],
5174 lib/silcutil/unix/silcunixschedule.c and the
5175 lib/silcutil/win32/silcwin32schedule.c.
5177 * Added new function silc_task_queue_wakeup to wakeup the
5178 scheduler by the specified task queue. Affected file
5179 lib/silcutil/silctask.[ch].
5181 * The silc_socket_host_lookup_start now wakes up the scheduler
5182 after adding the timeout task. Affected file is
5183 lib/silcutil/silcsockconn.c.
5185 * The silc_socket_host_lookup is synchronous now if the threads
5186 support is not compiled in. However, the callback is still
5187 called asyncronously through the scheduler, anyway. Affected
5188 file lib/silcutil/silcsockconn.c.
5190 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5192 * Added new function silc_socket_host_lookup to perform
5193 asynchronous IP and FQDN lookups for the socket connection.
5194 Affected files lib/silcutil/silcsockconn.[ch].
5196 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5198 * Added SILC_MUTEX_DEFINE to define the mutex on environments
5199 that may or may not compile the mutex support in.
5201 Changed the silc_mutex_alloc interface. It allocates the
5202 mutex now to the sent pointer and returns TRUE or FALSE.
5204 Affected file lib/silcutil/silcmutex.h.
5206 * Wrote the SILC Task Queue interface to support multi-threads.
5207 Affected file lib/silcutil/silctask.[ch].
5209 * Wrote the SILC Scheduler to support multi-threads. Affected
5210 file lib/silcutil/silcschedule.c.
5212 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5214 * Implemented the SILC Mutex API and SILC Thread API for WIN32
5215 in lib/silcutil/win32/.
5217 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5219 * Defined SILC Mutex API and SILC Thread API and implemented
5220 them for Unix. Affected files are
5221 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
5222 lib/silcutil/unix/silcunixmutex.c and
5223 lib/silcutil/unix/silcunixthread.c.
5225 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5227 * Fixed the silc_server_remove_clients_by_server's channel
5228 key re-generation. The hash table handling was incorrect
5229 and would not work with many channels. Affected file is
5232 * Fixed some memory leaks around the server code.
5234 * Rewrote the silc_server_get_users_on_channel to support IPv6
5235 based Client ID's. Affected file silcd/server.c.
5237 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
5238 specification. However, a separate document must be written
5239 to define the detailed signing procedure and the payload
5240 associated with the flag. Defined the flag to the
5241 lib/silccore/silcchannel.h as well.
5243 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5245 * Changed the dynamic tables to static size tables in the
5246 lib/silccrypt/silchmac.c.
5248 * Removed GCC dependencies from the code. A patch by cras.
5250 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5252 * Do not show the error "Error receiving packet bla bla"
5253 in server if it really was not an error (-2 means that reading
5254 is pending). Affected file silcd/server.c.
5256 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5258 * Fixed a possible crash in silc_server_remove_clients_by_server
5259 in silcd/server.c. Fixed there also some memory leaks.
5261 * Fixed the silc_idlist_replace_client_id. It could replace
5262 wrong key in the hash table. Affected file silcd/idlist.c.
5264 * Do not check whether there are global users on the channel
5265 if the channel->global_users is FALSE. Affected functions
5266 silc_server_remove_from_one_channel and
5267 silc_server_remove_from_channels in silcd/server.c. Also,
5268 do not check if the removed client is local as we can be
5269 sure that global client was not removed from the channel
5270 and checking for global users is not needed.
5272 * The silc_server_remove_clients_by_server now re-generates
5273 the channel keys correctly for those channels that had
5274 clients removed from them. Affected file silcd/server.c.
5276 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5278 * Found the reason of random crashes in the server. We weren't
5279 ignoring the SIGPIPE signal (which can be sent in write())
5280 and it crashed the server. Affected file silcd/silcd.c.
5282 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5284 * Assure that sock->user_data is not NULL in the function
5285 silc_server_packet_send in silcd/packet_send.c.
5287 * Disconnect the remote connection if it could not be added
5288 to any ID lists in the server. The affected file is
5291 * Check in silc_server_packet_send[_real/dest] that the
5292 socket is not disconnecting and ignore the data if it is.
5293 Affected file silcd/packet_send.c.
5295 * Define inline to __inline on native WIN32 compilation.
5296 Affected file includes/silcwin32.h.
5298 * Added some explicit type casts for inline code since MSVC
5299 require them. Affected files lib/silcutil/silcbuffer.h,
5300 lib/trq/silcdlist.h and lib/trq/silclist.h.
5302 * Print warning in log files from now on if the packet
5303 decryption fails. Affected file silcd/server.c.
5305 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5307 * Changed the `say' client operation's interface to accept
5308 new `type' argument to indicate the type of the message sent
5309 by the library. The application may filter the library's
5310 messages according the type. The affected file is the
5311 lib/silcclient/silcapi.h.
5313 * Added two new functions to lib/silcclient/silcapi.h:
5314 silc_client_del_client and silc_client_del_client_by_id.
5315 Affected file lib/silcclient/idlist.c.
5317 * Moved the clientincludes.h from includes/ to silc/ and
5318 serverincludes.h from includes/ to silcd/.
5320 * The modes for the CMODE and CUMODE are now passed as
5321 uint32 for application with COMMAND_REPLY. The affected
5322 file is lib/silcclient/command_reply.c.
5324 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5326 * /WHOIS without arguments shows client's own information.
5327 Affected file lib/silcclient/command.c.
5329 * Changed PING to not accept any arguments. The specs
5330 says that client can ping only the connected server so
5331 requiring an argument is not needed. Affected file is
5332 lib/silcclient/command.c.
5334 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5336 * Fixed a fatal bug in private message sending and reception
5337 encryption and decryption when using private message keys.
5338 The implementation was incorrect and did not follow the
5339 specification. It causd that some of the message were
5340 lost since it did not use the sending and receiving keys
5341 as the protocol suggests. This has been fixed and will cause
5342 incompatibilities with older clients when sending private
5343 message encrypted with private message keys. Affected files
5344 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
5345 and various other in Irssi SILC Client.
5347 Added `responder' boolean argument to the functions
5348 silc_client_add_private_message_key[_ske] to indicate when
5349 the key is added as responder or initiator of the key
5352 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5354 * Removed the silc_ske_check_version function and created
5355 a SilcSKECheckVersion callback. Added also a function
5356 silc_ske_set_callbacks that is now used to set all SKE
5357 callbacks. The callback functions are not given to
5358 the SKE functions anymore, but this function is used to
5361 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
5363 * Added `silc_version' argument to the silc_client_alloc
5364 to define the version of the application for the library.
5365 The library will use the version string to compare it
5366 against the remote host's (usually a server) version
5367 string. Affected file lib/silcclient/silcapi.h
5369 * Added the KE protocol context to Key Agreement context
5370 in client library so that we can abort the SKE if it
5371 is in process when we get timeout. Affected file is
5372 lib/silcclient/client_keyagr.c.
5374 * Do not resolve the client ID forever if it returns in the
5375 first time that such client does not exist. This was done
5376 for example with private message. Affected file is
5377 lib/silcclient/client_prvmsg.c.
5379 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5381 * Do not add regex.h for WIN32. The affected file
5382 includes/silcincludes.h.
5384 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
5385 not work yet 100%. It generates the DLL's automatically
5386 when compiling with --with-win32 under cygwin.
5388 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5390 * lib/contrib/regex.c is not compiled on WIN32.
5392 * Added silc_net_get_socket_opt function to the
5393 lib/silcutil/silcnet.h.
5395 * Added includes/silcwin32.h for WIN32 specific includes
5398 * Do not use ptime structure or any of the posix process
5399 functions on WIN32 in lib/silccrypt/silrng.c.
5401 * Added silc_gettimeofday to provide generic function
5402 for struct timeval on all platforms. Added the function
5403 to lib/silcutil/silcutil.h.
5405 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5407 * Moved the lib/silccore/silcsockconn.[ch] to the utility
5408 library as they clearly belong there. As a plus side we
5409 can make the actual socket connection routines platform
5412 Added also new generic function silc_socket_read and
5413 silc_socket_write (that used to be silc_packet_[read/write].
5414 The implementation of these are platform specific.
5416 * Added WIN32 specific routines of silc_socket_[read/write]
5417 to lib/silcutil/win32/silcwin32sockconn.c.
5419 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5421 * Added preliminary support for native WIN32 compilation under
5422 cygwin (using the -mno-cygwin option for GCC) to the
5423 ./configure.in.pre. The --with-win32 now prepares the
5424 compilation for native WIN32.
5426 * Rewrote the SILC Scheduler interface in the file
5427 lib/silcutil/silcschedule.h. The scheduler is now context
5428 based and does not have anymore any global static scheduler.
5429 Moved the Unix scheduler to the lib/silcutil/unix/ directory
5430 and created lib/silcutil/win32 directory for WIN32 based
5433 * Added Unix specific network routines to the
5434 lib/silcutil/unix/silcunixnet.c and the old
5435 lib/silcutil/silcnet.c includes now only generic routines.
5437 Added WIN32 specific network routines to the
5438 lib/silcutil/win32/silcwin32net.c.
5440 * Added Unix specific utility functions from the
5441 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
5443 * Added WIN32 SILC Scheduler to the file
5444 lib/silcutil/win32/silcwin32schedule.c. The code is of course
5447 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5449 * Do not handle JOIN notify in the server if the target client
5450 is not registered (idata->registered == FALSE). The affected
5451 file is silcd/packet_receive.c.
5453 * Update the nickrec->founder in event_cumode in the Irssi SILC
5454 client. Affected file irssi/src/silc/core/silc-channels.c.
5456 * Fixed the CUMODE_CHANGE notify handling in the server when
5457 server and router are announcing their clients on channels.
5458 Now the mode changes are saved and notified correctly. The
5459 affected file is /silcd/packet_receive.c.
5461 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
5462 They really did not replace the cache entry in the ID Cache.
5463 Now they do that. Affected file silcd/idlist.c.
5465 * Fixed the KICK notify handling in the Irssi SILC client to
5466 update the channel records so that the kicked client does not
5467 appear to be on the channel. The affected file is
5468 irssi/src/silc/core/silc-channels.c.
5470 * Always update the conn->current_channel when executing command
5471 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
5473 * Fixed the KILL notify handling in Irssi SILC client to remove
5474 the killed client on all channels.
5476 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5478 * Fixed the silc_parse_command_line to remove extra spaces
5479 from the start and end of the arguments. Affected file is
5480 lib/silcutil/silcutil.c.
5482 * Cancel and free any active protocol in the function
5483 silc_server_close_connection. Affected file silcd/server.c.
5485 * Cancel and free any active protocol in the function
5486 silc_client_close_connction. Affected file is
5487 lib/silcclient/client.c.
5489 * Do not execute the KILL command for clients that are in
5490 history (ie. they are not in the network). Affected file is
5493 * Fixed KILL notify handling, client does not crash anymore.
5494 Affected file irssi/src/silc/core/silc-channels.c.
5496 * Reduced the default packet buffer size from 2048 to 1024 in
5497 lib/silccore/silcpacket.c.
5499 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5500 counter to the SKE context that is incresed when the SKE library
5501 performs async operation outside the library. If the outside
5502 process frees the SKE context and FREED status will be set
5503 and the library will detect after the sync operation that the
5504 libary is freed. The affected files are
5505 lib/silcske/silcske[_status].[ch].
5507 * Resolve the client entry information in the function
5508 silc_client_channel_message to assure that NULL pointer is not
5509 passed as client entry to the application. */
5511 * Fixed the task timeout calculation to assure that there is
5512 never negative timeouts. The affected file is
5513 lib/silcutil/silcschedule.c.
5515 * Fixed the channel user mode notification sending in server.
5516 It was sent point-to-point to the router (or to server by router)
5517 but it needs to be destined to a channel. The routines now
5518 supports sending the channel user mode notifys to the channels
5519 when announcing clients and channels. Affected files are
5520 silcd/server.c and silcd/packet_receive.c.
5522 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5523 It did not actually replace the old channel entry in the cache.
5524 Affected file lib/silcclient/client_notify.c.
5526 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5528 * Fixed a possible crash in silc_packet_send_prepare. It now
5529 assures always that there is enough space in the buffer and
5530 at the tail area of the buffer (for MAC).
5532 Fixed the inbound buffer reallocation in silc_packet_read.
5533 It was old code and did not handle the reallocation correctly.
5536 The affected file is lib/silccore/silcpacket.c.
5538 * Fixed buffer overflow in silc_parse_nickname in the file
5539 lib/silcutil/silcutil.c.
5541 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5543 * make install generates new server keys only if there is not
5546 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5548 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5549 Added check that if the NOREPLY is set then we will not send
5550 the away message. This avoids infinite loop of away messages
5551 if both clients are away. The affected file is
5552 lib/silcclient/client_prvmsg.c.
5554 * Fixed client crash if /NICK was given without arguments.
5555 Affected file lib/silcclient/command.c.
5557 * Server does not send the invite list in INVITE command back
5558 to the client if the list was not altered. Added this notion
5559 to the protocol spec as well. Affected file silcd/command.c.
5561 Fixed possible crash in INVITE command by checking the
5562 value of silc_server_get_client_route command.
5564 * Fixed the INVITE notify type handling. The arguments are now
5565 taken in correct order and client does not crash. The affected
5566 file is irssi/src/silc/core/silc-channels.c.
5568 Removed the "Inviting xxx to channel" message from the
5569 client library away and let the application handle it.
5570 Affected file lib/silcclient/command.c. Added that message
5571 to Irssi SILC client's message formats.
5573 * Fixed CMODE command crash in client. It now checks the
5574 amount of arguments correctly and does not crash. The affected
5575 file is lib/silcclient/command.c.
5577 * Do not create new channel automatically in silc_channels_join
5578 but check whether the channel by that name already exists.
5579 Affected file irssi/silc/core/silc-channels.c.
5581 * Do not send the SERVER_SIGNOFF to router if the disconnected
5582 entity was the router. Affected file silcd/server.c.
5584 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5585 SILC client as it was missing from there.
5587 Added the handling of the KICK notify to the Irssi SILC client
5588 as it was missing. Added "you have been kicked" message to
5589 Irssi SILC client's message modules formats.
5591 Added the handing of the KILL notify to the Irssi SILC client
5592 as it was missing. Added the kill message module formats
5595 The affected file is irssi/src/silc/core/silc-channels.c.
5597 * The router did not save the channel mode the server announced.
5598 Affected file silcd/packet_receive.c.
5600 * Fixed a possible crash in INFO command in server. If the
5601 server did not provide the server info it crashed. Affected
5602 file silcd/command.c.
5604 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5606 * Fixed the GETKEY command in the server to check also the
5607 global list. Otherwise the GETKEY would not work correctly
5608 in normal SILC server. Affected file silcd/command.c.
5610 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5612 * Fixed GETKEY crash, it crashed if the command did not succseed.
5614 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5616 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5617 is now real and not just an macro interface to GMP.
5619 Removed the entire GMP from the source tree and imported new
5620 NSS MPI library instead. Reason for removing GMP is that it is
5621 extremely large and compiles extremely slow. The NSS MPI
5622 is only a few files and compiles in less than 10 seconds.
5623 The speed is also about the same as GMP. The MPI is imported
5624 to lib/silcmath/mpi.
5626 If the system has GMP installed we will still use the GMP.
5627 If it is not then the NSS MPI will be compiled.
5629 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5631 * Merged a long nickname (127 characters long) crash bugfix from
5632 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5634 * Merged a freed memory reference bugfix from Irssi CVS tree.
5635 Affected file irssi/src/core/commands.c.
5637 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5639 * Added the server's public key sving and verification to the
5640 server when performing the SKE. This was missing and the
5641 remote server's (or router's) public key was accepted without
5642 checking whether we have it previously or trust it at all.
5643 Affected file silcd/protocol.c.
5645 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5647 * Check in the silc_server_timeout_remote if protocol is active
5648 and make sure that the protocol's final callback is called so
5649 that all memory if freed. Affected file silcd/server.c.
5651 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5653 * silc_server_whois_send_reply crashed the server if the nickname
5654 was 127 characters long. Affected file silcd/command.c.
5656 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5658 * Added sanity check to the silc_server_new_client. If the hostname
5659 is provided inside username then check that the provided hostname
5660 really is the same as the resolved one. If the hostname was not
5661 resolved then check it from the public key. Affected file is
5662 silcd/packet_receive.c.
5664 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5665 if the server disconnected us and the connection is not valid
5666 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5668 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5669 the library to the lib/silcutil/silcutil.[ch].
5671 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5673 * Close log file after open. Affected file
5674 lib/silcutil/silclog.c.
5676 * Check whether sock == NULL in silc_client_send_packet and return
5677 if it is. Affected file lib/silcclient/silcclient.c.
5679 * Check rec->entry == NULL in the Irssi SILC Client before
5680 sending the channel message. Affecte file is
5681 irssi/src/silc/core/silc-servers.c.
5683 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5685 * Merged a splitted window bugfix from Irssi CVS tree. The
5686 affected file is irssi/src/fe-text/textbuffer-view.c.
5688 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5689 It did not print nickname.
5691 * Improved the distributions system a bit.
5693 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5695 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5696 irssi/src/fe-text/gui-window.c.
5698 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5699 to in-active server. The affected file is
5700 irssi/src/silc/core/client_ops.c.
5702 * Resolve the client in USERS command reply if the entry does
5703 not have username resolved. The affected file is
5704 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5705 command to WHOIS command to really resolve stuff. The USERS
5706 is not used any more in any critical section so WHOIS can
5707 be used even though it might be slower than IDENTIFY.
5709 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5712 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5714 * Changed the protocol API a bit more consistent in the
5715 lib/silccore/silcprotocol.[ch].
5717 * Changed the following headers to ROBODoc format:
5719 lib/silccore/silcpayload.h
5720 lib/silccore/silcprotocol.h
5721 lib/silccore/silcsockconn.h
5723 All core library headers are now formatted.
5725 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5727 * Fixed a bug in Irssi SILC client; do not show that you are
5728 server/router operator if you really are not. Affected file is
5729 irssi/src/silc/core/client_ops.c.
5731 * Renamed silc_command_free_payload to silc_command_payload_free.
5732 Affected file lib/silccore/silccommand.h
5734 * Added silcmath.h to include the prototoypes of various routines
5735 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5738 * Changed the following headers to ROBODoc format:
5740 lib/silccore/silcchannel.h
5741 lib/silccore/silccommand.h
5742 lib/silccore/silcid.h
5743 lib/silccore/silcidcache.h
5744 lib/silccore/silcmode.h
5745 lib/silccore/silcnotify.h
5746 lib/silccore/silcpacket.h
5747 lib/silcmath/silcmath.h
5749 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5751 * Added checking to the server code not to start the server if
5752 ciphers and stuff are not configured properly. Affected files
5753 silcd/serverconfig.[h] and silcd/server.c.
5755 * Changed the layout of the header files of the public interfaces
5756 in the SILC libraries. The new layout supports ROBODoc
5757 documentation tool (and some others) so that it is easy to create
5758 a library reference manual. All the other headers and source
5759 code must still follow the CodingStyle document. Also source
5760 code must not include these ROBODoc stuffs, only the headers.
5761 Furthermore, all public interface headers must now be named
5762 by using `silc' prefix, example: silcapi.h, silccipher.h.
5763 Some files were renamed due to this. All the other headers
5764 must not be used as public interfaces. I will update the
5765 CodingStyle document later. Changed following headers, so far:
5767 lib/silcclient/silcapi.h
5768 lib/silccore/silcauth.h
5769 lib/silccore/silcprivate.h
5770 lib/silccrypt/silcdh.h
5772 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5776 * Removed silc_client_packet_send_flush from the client library
5777 as it is not needed. Affected file lib/silcclient/client.[ch].
5779 * Added printing of message of unresolved authentication method
5780 to the Irssi SILC client. Added it to the module formats.
5781 Removed the same message from the client library.
5783 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5785 * Added new distribution feature, DISTLABEL. Every distribution
5786 can define own preprocessor label that can be used in the
5787 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5788 file distributions, acconfig.h.pre and prepare.
5790 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5792 * Added Makefile.defines_int to include the actual definitions
5793 for Makefile.defines.in. Tested the new distribution system,
5794 created distributions and tested installation.
5796 * Added AWAY message printing to the Irssi SILC client. Added
5797 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5799 * Added SCONNECT command to call the SILC's CONNECT command.
5800 Cannot use CONNECT directly since Irssi uses that internally.
5801 Affected file irssi/src/silc/core/silc-servers.c.
5803 Added ACTION local command. It is same as ME command but takes
5804 the channel as mandatory argument.
5806 Rewrote some of the Irssi's help files to suite for SILC
5809 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5811 * Added Makefile.defines[.in] that should for now on be included
5812 in all Makefile.am file in the source tree. That file includes
5813 all common compilation definitions for SILC source tree.
5815 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5817 * Minor changes to the ./prepare script to change the package
5818 name according the distribution name to the configure.in.
5820 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5822 * Created new distribution system. Added file `distributions'
5823 that defines all the distributions that can be created out of
5824 the SILC source tree. The ./prepare script now reads that
5825 file to determine how to prepare the distributions. The
5826 first argument to the ./prepare is the name of the distribution
5827 and second is the version of the distribution. If given
5828 without arguments it creates the default (toolkit) distribution
5829 with the default version (defined in ./prepare).
5831 All Makefile.am files that are subject to the distributions
5832 are now named as Makefile.am.pre. These are ./Makefile.am
5833 and lib/Makefile.am. Others may be changed later.
5835 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5837 * Added invite list, ban list, some key management and connection
5838 error message printing to module formats in the Irssi SILC client.
5840 * Added new silc_client_set_away_message to set the away message
5841 that is back to the person who sent private message. The
5842 affected file lib/silcclient/silcapi.h and the
5843 lib/silcclient/client_prvmsg.c.
5845 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5847 * Fixed the private message sending in the Irssi SILC client,
5848 added local command KEY to the Irssi SILC client.
5850 Added key management and key agreement message formats to the
5851 irssi/src/fe-common/silc/module-formats.[ch].
5853 Added USERS (alias WHO) printing, server/router operator
5854 indication and LIST command printing to the module formats.
5856 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5858 * Fixed channel joining notify handling, cumode notify handling
5859 from Irssi SILC client.
5861 * Added SILC specific module-formats to the Irssi SILC client so
5862 that SILC specific message hilighting, colors etc is possible.
5863 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5865 Added channel mode, channel user mode, actions, notices,
5866 whois and whowas printing to the the module-formats.c.
5868 * Fixed a bug in channel deletion in the server. The channel
5869 is not left to the cache even if the channel founder auth mode
5870 is set when there are no users anymore on the channel. Affected
5871 file silcd/server.c.
5873 * The silc_net_localhost now resolves the entire hostname including
5874 the domain name. Affected file lib/silcutil/silcnet.c.
5876 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5878 * Changed the ask_passphrase client operation to be ascynchronous.
5879 It has now a completion callback and a context that the
5880 application must call after it has got the passphrase from
5881 the user. Affected files lib/silcclient/silcapi.h,
5882 lib/silcclient/protocol.c, lib/silcclient/command.c and
5885 Added SilcAskPassphrase callback that the application calls
5886 to deliver the passphrase to the library.
5888 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5889 The public key verification and especially a certificate
5890 verification is asynchronous procedure.
5892 Added new SILC_SKE_STATUS_PENDING status to indicate the
5893 request is pending and a callback will be called to finalize
5896 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5897 indicate that remote end did not send its public key (or
5898 certificate), even though we require it. Added check for this
5899 condition in the SKE. This was a security bug, now fixed.
5901 Defined new SilcSKEVerifyCbCompletion callback that is called
5902 when the verification process is completed.
5904 The affected files lib/silcske/silcske_status.h and
5905 lib/silcske/silcske.[ch].
5907 * Changed the verify_public_key client operation to be async
5908 as well. Defined SilcVerifyPublicKey callback that is used to
5909 indicate the success of the public key verification process.
5911 Changed the server and client to use the new async client
5914 * Changed the Irssi SILC client's internal scheduler to be called
5915 twice as many times as it used to be. As a result the client
5916 should be a bit faster now. Affected file is
5917 irssi/src/silc/core/silc-core.c.
5919 * Added support to Irssi SILC client of asynchronous public key
5920 verification and passphrase inquiry. Affected file is
5921 irssi/src/silc/core/silc-core.c.
5923 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5925 * Do not say "You have left channel %s" in client library.
5926 Moved it to the application. Affected files are
5927 lib/silcclient/command.c and silc/client_ops.c.
5929 * Fixed silc_client_get_clients. Command context was not
5930 duplicated and was freed memory in the callback. Affected
5931 file lib/silcclient/idlist.c.
5933 * Do not say "you are now talking..." on JOIN command in the
5934 client library. The appliation must handle it.
5936 * Do not say ".. changed topic to" in command reply in the
5937 client libary. The application must handle it.
5939 * Fixed TOPIC command sending in the client library.
5941 * Fixed a memory leak in silc_client_command_free in the file
5942 lib/silcclient/command.c.
5944 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5946 * Imported a modified version of Irssi client to the source tree.
5947 The Irssi will be used to create a new client called
5948 Irssi SILC. Imported to irssi/.
5950 Added silc_core_init_finish function to the Irssi. Affected
5951 file irssi/configure.in.
5953 A lot changes in the Makefile.ams around the irssi tree.
5955 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5957 * Do not rehash if the new size is same as the old size of the
5958 hash table, in the silc_hash_table_rehash*. The affected file
5959 lib/silcutil/silchashtable.c.
5961 * Replaced hash_table_del_by_context calls from the server
5962 (when channel->user_list and client->channels) to the
5963 hash_table_del as it is sufficient and faster.
5965 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5967 * Added silc_hash_table_list, silc_hash_table_get and the
5968 SilcHashTableList structure to provide an alternative way to
5969 traverse the hash table. The affected files are
5970 lib/silcutil/silchashtable.[ch].
5972 * Changed the server's idlist routines to use the hash table
5973 routines to optimize the code.
5975 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5977 * Replaced the client entry's `channel' list and channel entry's
5978 `user_list' list to hash tables for optimized lookup. Changed
5979 the code to use the hash table interface around the code.
5980 Affected file lib/silcd/idlist.[ch].
5982 * Added `auto_rehash' boolean argument to the function
5983 silc_hash_table_alloc to indicate whether the hash table should
5984 auto-rehash when it thinks is appropriate time. It will
5985 increase the hash table size if the there is twice as much
5986 entries in the table than the size of the table, and will
5987 decrease the size if there are twice as less entries than
5988 the size of the table.
5990 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5992 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5994 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5996 * silc_idcache_purge_by_context deletes the entry now by context
5997 as it is supposed to do. Affected file lib/silccore/idcache.c.
5999 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
6000 client is not anymore valid (WHOWAS givens the info) and not
6001 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
6003 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6005 * Removed the `data' and `data_len' arguments from the ID Cache
6006 interfaces and added `name' argument. ID Cache does not handle
6007 anymore the binary data only a names associated with given ID.
6009 * When hashing a Client ID with silc_hash_id the entire ID is
6010 not hashed anymore, instead only the hash of the Client ID is
6011 hashed. This way we can access the Client ID from the cache
6012 with Client ID but with the hash of the ID (which is a hash of
6013 the nickname) as well without any difference in performance.
6015 Added also silc_idcache_find_by_id_one_ext to do one on one
6016 searching when we have the actual ID. Added also function
6017 silc_hash_client_id_compare. The affected files are
6018 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
6020 * When hashing the name associated with a ID it is always done
6021 in lowercase. This way we can access the cache without worrying
6022 about case-sensitivity, even though, for example nicknames are
6025 * Fixed a bug in server with channel message sending. It put
6026 wrong ID type as destination ID. The affected file
6027 silcd/packet_send.c.
6029 * silc_idcache_del_by_context now deletes from all hash tables
6030 by context. Affected file lib/silccore/idcache.c.
6032 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6034 * Changed the client library to use the new ID Cache interface.
6035 Changes around the source tree.
6037 * Added silc_hash_table_rehash_ext to rehash with specific
6038 hash function. Affected file lib/silcutil/silchashtable.[ch].
6040 * Added silc_hash_string_compare to compare two strings in the
6041 hash table. Affected file lib/silcutil/silcutil.[ch].
6043 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6045 * Added new function silc_idcache_del_by_context into the
6046 lib/silccore/idcache.[ch].
6048 * Changed the server's ID list routines to use the new ID Cache
6049 interface. Changes around the source tree.
6051 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6053 * Added silc_hash_table_del[_by_context]_ext functions in to the
6054 lib/silcutil/silchashtable.[ch].
6056 Removed silc_hash_table_find_all* routines and added new
6057 silc_hash_table_find_foreach to replace them.
6059 Added silc_hash_table_replace_ext function as extended
6060 replacing function. Separated the simple hash table interface
6061 from the extended hash table interface in the file
6062 lib/silcutil/silchashtable.h.
6064 * Fixed minor bugs and changed it to use some of the new
6065 hash table functions in lib/silccore/idcache.c
6067 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6069 * Added new function silc_hash_table_find_all to return all keys
6070 in the hash table by the specified key. As the hash table is
6071 collision resistant it also makes it possible to have several
6072 duplicate keys in the hash table. This function may be used to
6073 find all of the keys from the hash.
6075 Added user_context arguments to the SilcHashFunction,
6076 SilcHashCompare and SilcHashDestructor to deliver user specified
6079 Added new fuctions silc_hash_table_find[_all]_ext to do
6080 extended lookup with specified hash and compare functions and
6081 specified user contexts.
6083 Added new function silc_hash_table_add_ext to add the key
6084 with specified hash function and user context.
6086 Added new function silc_hash_table_foreach to traverse all
6087 entrys in the hash table. Added SilcHashForeach callback
6090 Added new function silc_hash_table_del_by_context to delete
6091 the entry only if the context associated with the key matches.
6093 Affected files are lib/silcutil/silchashtable.[ch].
6095 * Removed silc_hash_[server/client/channel]_id and added just
6096 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
6097 silc_hash_id_compare to compare two ID's using as the hash table
6098 comparison function. Added also silc_hash_data to hash
6099 binary data and silc_hash_data_compare to compare it.
6101 * Removed silc_idlist_find_client_by_hash as it is not needed
6102 anymore. Affected file silcd/idlist.[ch].
6104 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
6105 to use internally the SilcHashTable. The new ID Cache is a lot
6106 faster than the old one. Some of the ID Cache interface was also
6107 rewritten and obsolete and stupid functions were removed.
6109 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6111 * Added entry_count field to the SilcHashTable to keep the number
6112 of the entries in the table. Implemented the function
6113 silc_hash_table_rehash. Added new function
6114 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
6116 Fixed a minor bug in silc_hash_table_free.
6118 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
6119 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
6120 into the lib/silcutil/silcutil.[ch].
6122 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6124 * Implemented a collision resistant hash table into the
6125 lib/silcutil/silchashtable[ch]. See the header and the source
6126 for the SilcHashTable API.
6128 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6130 * Merged dotconf version 1.0.2 into lib/dotconf.
6132 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6134 * Do not compile anything in lib/silcsim/* if the SIM support
6135 is not enabled. The tree should now compile without problems
6138 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6140 * Compiled the SILC under cygwin. Compiled and tested briefly
6141 without problems. More tests needed. The SIMs didn't compile
6144 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
6146 * Fixed possible crash in silc_get_username in the
6147 lib/silcutil/silcutil.c.
6149 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6151 * Fixed a va_arg in silc/client_ops.c.
6153 * Oops, RC5 routines were named AES and caused some problems
6154 when not using SIM's. Affected file lib/silccrypt/rc5.c.
6156 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6158 * Added new SilcIDIP structure into the lib/silccore/id.h and
6159 replaced the old `ip' fields from all SILC ID's to that type.
6160 This is a step towards IPv6 support.
6162 The silc_id_get_len takes now the ID as an extra argument.
6163 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
6164 both IPv4 and IPv6 based ID's.
6166 The affected files are lib/silccore/id.[ch] and other files
6167 around the tree using these routines.
6169 * Removed the ID length arguments in server from various
6170 silc_server_send_notify_* routines -> they are not needed
6173 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6175 * Fixed memory leak in silc_encode_pem_file in the file
6176 lib/silcutil/silcutil.c.
6178 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6180 * Check minor version as well in the SKE. Affected files are
6181 silcd/protocol.c and lib/silcclient/protocol.c.
6183 * Added --identifier option to the server so that an identifier
6184 can be when creating the public key for the server. Affected
6185 file is silcd/silcd.c.
6187 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
6188 lib/silccrypt/silcpkcs.c.
6190 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6192 * Register default ciphers and stuff when using -C option with
6193 the server. Affected file sildc/silcd.c.
6195 * Put back the servers public key filename format, it is better
6196 than the new one. For now, the client keys are saved with the
6197 new filename format. The affected file silc/client_ops.c.
6199 * Implemented the Cipher API for the rest of the ciphers that
6200 did not implement it or implemented it the wrong way.
6202 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6204 * Register default ciphers and stuff when using the -S option
6205 in the client. Affected file silc/silc.c. Same also when
6206 creating new key pair with -C option.
6208 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6210 * Fixed the silc_verify_public_key client operation function to
6211 save the public keys differently. The fingerprint is now
6212 used as filename and not the hostname. This way also the
6213 client keys are saved uniquely and not with hostnames. The
6214 affected file is silc/client_ops.c.
6216 * Trimmed the silc_hash_fingerprint function to remove extra
6217 whitespaces from the end of the fingerprint. The affected
6218 file is lib/silccrypt/silchash.c.
6222 * Added silc_cipher_register_default function to register all
6223 default ciphers. It can be used when configuration files
6224 does not exist and the application does not want any specific
6225 ciphers in any specific order.
6227 The SilcDList is now used as silc_cipher_list dynamically
6228 allocated cipher list. Removed the static list all together
6229 and now all ciphers must be allocated to the dynamic list.
6230 The silc_cipher_alloc routine was changed to check only the
6233 All silc_cipher_* routines that used to return int returns
6236 The affected files lib/silccrypt/silccrypt.[ch].
6238 * The same thing was done to silc_hash_* as for silc_cipher_*
6239 routines. Affected files lib/silccrypt/silchash.[ch].
6241 * The same thing was done to silc_pkcs_* as for silc_cipher_*
6242 routines. Affected files lib/silccrypt/silcpkcs.[ch].
6243 Added also silc_pkcs_[un]register[_default] functions.
6244 Removed the data_context from the PKCS API.
6246 * Added silc_hmac_register_default function to register default
6247 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
6248 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
6249 to unregister all hmacs at once.
6251 * Register the default ciphers, hash functions, PKCSs and HMACs
6252 if client's configuration file does not exist. The affected
6255 * The client did not load the hash functions from the SIM
6256 modules at all. Added support for this. Affected file is
6257 silc/clientconfig.c.
6259 * When decoding public key with silc_pkcs_public_key_decode, check
6260 the supported algorithm only if PKCS are registered. Affected
6261 file lib/silccrypt/silcpkcs.c. The same was done with the
6262 silc_pkcs_private_key_decode.
6264 * Fixed the SILC List routines to keep the list always in order.
6265 It used to change the list's order when traversing the list but
6266 not it preserves the order. Affected file lib/trq/silclist.h.
6268 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6270 * Added the client library to use the SilcSocketConnection's
6271 reference counter (by silc_socket_dup) to prevent the bug that
6272 the socket object may be freed underneath async operation.
6274 * The name resolv library checking fixes in the configure.in.pre.
6277 * Created new version of the protocol drafts for future
6278 development. The -03 drafts are the ones that will be changed
6279 in the trunk now and the -02 will remain as they are.
6281 * Send list of CUMODE notifys to the router when announcing
6282 the channel users to the router. Affected file silcd/server.c.
6283 If the router receiving channel founder CUMODE for a channel
6284 that already has channel founder it will send CUMODE notify
6285 to the sender to remove the channel founder rights from the
6286 announced client. Affected file silcd/packet_receive.c.
6288 * The CUMODE notify may now use Server ID as well as the entity
6289 who changes the mode. Updated protocool specs.
6291 * Updated INSTALL and README files.
6293 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6295 * New web pages in the http://silc.pspt.fi. The pages was
6300 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6302 * Implemented the [DenyConnectin] config section in the server.
6303 Added silc_server_config_denied_conn to check whether incoming
6304 connection is denied. Affected file silcd/serverconfig.[ch].
6306 * Do not check the ports when checking the incoming configuration
6307 data if the port is 0, meaning any. Affected file is
6308 silcd/serverconfig.c.
6310 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6312 * Fixed buffer overflow in silc_string_compare in the file
6313 lib/silcutil/silcutil.c.
6315 * Fixed double free in silc_server_command_leave in the file
6318 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6320 * Fixed the version checking in the server. Affected file is
6323 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6325 * Fixed the configuration data fetching when accepting new
6326 connections in the server. Affected file silcd/server.c.
6328 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6330 * Added `sender_entry' argument to the function
6331 silc_server_packet_relay_to_channel so that we can check
6332 whether some destination actually belongs to the same route
6333 the sender belongs (ie, we must not resend the packet to the
6334 sender). Affected file silcd/packet_send.[ch].
6336 * Added `servername' field to the SilcClientEntry in the server
6337 to hold the name of the server where client is from. Affected
6338 file is silcd/idlist.h.
6340 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6342 * Moved the channel message encrypting in the router betwen
6343 router connections from silc_server_channel_message to the
6344 silc_server_packet_relay_to_channel since we want to check
6345 whether we have anybody channel before encrypting anything.
6346 Affected files silcd/packet_[receive/send].c.
6348 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6350 * Fixed the [AdminConnection] server config section to support
6351 multiple entries. Affected file silcd/serverconfig.c.
6353 * Added support into the server to check the validity of the
6354 incoming connection before executing any KE or authentication
6357 * The connection configuration is now saved to the KE and
6358 connection auth protocol contexts and not fetched anymore in
6359 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
6361 * The local hosts listenning address and port is also resolved
6362 now when starting the server. We want to have the socket object
6363 to include the real address and port for the listener. Added
6364 new function silc_net_check_local_by_sock into the files
6365 lib/silcutil/silcnet.[ch].
6367 * Fixed a broadcast bug in server -> do not broadcast if we
6370 * Fixed a routing bug. Do not route broadcast packets ever.
6371 Broadcast packets must be processed always and not routed since
6372 they may be destined to some other host than yourself and thus
6373 would get routed without no good reason. Affected file is
6376 * Added function silc_server_config_is_primary_route to check
6377 whether primary router connection has been configured (a router
6378 configuration that we are initiating). If there is not, we
6379 will assume that there is only two routers in the SILC network
6380 and we will use the incoming router connection as our primary
6381 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
6383 * Changed the order of the broadcasting. Broadcast _after_ the
6384 packet has been processed not before. Affected file is
6387 * Fixed a [ClientConnection] parsing bug. The port was never
6388 parsed correctly thus resulting to port 0. Affected file
6389 silcd/serverconfig.c.
6391 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
6392 argument and did not set the broadcast packet flag. Affected
6393 file silcd/packet_send.c. Fixed same bug in the function
6394 silc_server_send_notify as well.
6396 * If we receive NEW_ID packet for our own ID in the server, ignore
6399 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6403 * Removed the nickname from the Private Message Payload.
6404 Updated the code and the protocol specs.
6406 * Updated protocol specs for submitting to the IETF.
6408 * Tweaked the Random Number Generator a bit. Affected file
6409 lib/silccrypt/silcrng.c. Exported a new function
6410 silc_rng_[global]_add_noise which can be used to add more
6413 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6415 * Do not parse packets with different timeout when protocol
6416 is active -> may cause problem with rekey. Affected file
6419 * When server receives signoff notify it must not create
6420 new channel key if the client is on any channels since the
6421 sender of the signoff notify will create it.
6423 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6425 * Added printing of error messages during SKE protocol from the
6426 failure packet sent by server during SKE. Affected file
6429 * Removed the client's failure_callback handling with timeout
6430 and handle it immediately when received.
6432 * The SKE library returned wrong type in SUCCESS and FAILURE
6433 packets. They must be 32 bit MSB not 16 bit MSB.
6435 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6437 * Ok, rewrote the logic of the re-key and now it seems to work.
6438 I tested it on high traffic with frequent re-keys without
6439 problems. Added hmac_receive (and renamed hmac to hmac_send)
6440 in SilcClientConnection in lib/silcclient/client.h and
6441 in SilcIDListData in silcd/idlist.h. Also, removed the
6442 SilcPacketParserContext's cipher and hmac fields as they are
6443 not needed anymore and actually caused some problems when
6444 the ciphers and hmac's changed underneath the packet parser.
6446 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6448 * If re-key protocol is active then process the incoming packets
6449 synchronously since we must assure that icoming packets encrypted
6450 with the old key is processed before the new keys is set to
6451 use. This is true other packets than for REKEY packets.
6452 Affected file silcd/server.c. The same was done to client library
6453 as well, affected file lib/silcclient/client.c.
6455 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6457 * Fixed bug in client and server to accept the force send if
6458 the packet is send from silc_[server/client]_packet_process
6459 function. Otherwise the packets are never delivered, oops.
6461 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6463 * Disable force sending of packets when REKEY protocol is active.
6464 We must assure that no packet is sent directly when rekey is
6465 performed. All packets must be sent through packet queue.
6466 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
6467 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
6468 function is silc_[server/client]_packet_send_real to check
6471 * Replaced the SIM paths from example config files to
6472 /usr/local/modules. Also, make install creates now
6473 /usr/local/silc/logs directory to hold all the SILC server
6476 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6478 * Made the configure.in.pre work on Solaris. Patch by salo.
6480 * Made all ciphers compatible with non-x86 machines. Defined
6481 CBC mode macros into lib/silccrypt/ciphers_def.h.
6483 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6485 * Fixed the make install.
6487 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6489 * When MAC computation fails the silc_packet_decrypt returned 0
6490 even though it was supposed to return -1. Fixed this. The
6491 affected file is lib/silccore/silcpacket.c.
6493 * Do not replace the config files in /etc/silc (in make install)
6494 if they already exist. Affected file ./Makefile.am.
6496 * Do not send re-key packets immediately but through packet queue.
6497 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6499 * Changed silc_net_check_host_by_sock to return FALSE if the
6500 IP/DNS could not be resolved. Though, it returns the IP address
6501 now even if it could not resolve it (but returns also FALSE).
6502 Affected file lib/silcutil/silcnet.[ch].
6504 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6506 * Added silc_pkcs_decode_identifier to decode the public key's
6507 identifier. Affected file lib/silccrypt/silpkcs.[ch].
6508 Added also silc_pkcs_free_identifier. Added also new context
6509 SilcPublicKeyIdentifier.
6511 * Added -S option to the silc client. It is used to dump the
6512 contents of the specified public key file.
6514 * Changed the PKCS api to return the public key length when
6515 setting the public key.
6517 * Fixed a fatal bug in the public and private key file loading.
6518 Affected file lib/silccrypt/silcpkcs.c.
6520 * Execute the packet parsing for client with zero (0) timeout
6521 if the protocol is active. Affected file silcd/server.c.
6523 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6525 * Made the key generation options to the silcd program. Added
6526 -C option, equivalent to client's option.
6528 * Added new [ServerKeys] config section to the server. It
6529 configures the server's public and private key.
6531 * Defined generic Public Key Payload into the protocol
6532 specification to send specific type of public keys and
6535 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6536 public key or certificate.
6538 * Implemented the GETKEY command to the server and to the
6539 client library and on user interface.
6541 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6543 * Made preliminary `make install' work.
6545 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6547 * Added SilcServerRekey context into silcd/idlist.h.
6549 * Added the PFS support as defined in the specification to the
6550 SKE protocol. Affected files lib/silcske/*.c.
6552 * Added `ske_group' field to the SilcServerRekey context to hold
6553 the number of the SKE group that is used with PFS in re-key.
6554 Affected file silcd/idlist.h.
6556 * Added PFS re-key support to the server. Affected file is
6559 * Added silc_protocol_cancel to cancel execution of the next
6560 state of the protocol. Affected file is
6561 lib/silccore/silcprotocol.[ch].
6563 * Added the re-key support with and without PFS to the client
6564 library. Re-key is performed once in an hour, by default.
6566 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6567 Added silc_client_rekey_callback and silc_client_rekey_final.
6568 Affected files are lib/silcclient/protocol.[ch] and
6569 lib/silcclient/client.[ch].
6571 * Removed the `hmac_key' and `hmac_key_len' fields from the
6572 SilcClientConnection structure; not needed. Affected file is
6573 lib/silcclient/client.h.
6577 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6579 * Do not ask whether user wants to use the negotiated private key
6580 for private messages, just use it. Affected file is
6581 silc/local_command.c.
6583 * Added `send_enc_key' and `enc_key_len' fields to the
6584 SilcIDListData structure since they are needed in the re-key
6585 phase. Affected file is silcd/idlist.[ch].
6587 * Implemented the simple re-key protocol into the server.
6588 Affected files silcd/server.c and silcd/protocol.[ch]. The
6589 re-key will be performed once in an hour, by default.
6591 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6592 Added silc_server_rekey, silc_server_rekey_callback and
6593 silc_server_rekey_final.
6595 * Removed Tunneled flag from the protocol. Updated the code
6596 and the specifications.
6598 * Adde `pfs' field to the SilcIDListData to indicate whether
6599 the PFS is to be performed in the re-key. Affected file is
6602 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6604 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6605 int64 of at least the xintXX size. If void * is less that 4
6606 bytes uint32 * will be used. Defined bool as boolean.
6608 * Changed _ALL_ unsigned long and unsigned int to uint32,
6609 unsgined short to uint16 in the source tree.
6611 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6612 not handle clients that has entry->data.registered == FALSE.
6613 They are not in the network anymore. Affected file is
6616 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6618 * Implemented the sending of the SERVER_SIGNOFF notify in the
6619 server. Affected file is silcd/server.c.
6621 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6622 Added also silc_notify_payload_encode_args into the
6623 lib/silccore/silcnotify.[ch].
6625 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6626 Affected file silcd/packet_receive.c.
6628 * Implemented the SERVER_SIGNOFF notify handling in the client
6629 library. Affected file lib/silcclient/client_notify.c. Also,
6630 implemnted the printing of the SERVER_SIGNOFF info to the
6631 application. Affected file silc/client_ops.c.
6633 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6634 if the deleting was successful. Affected file silcd/idlist.[ch].
6636 * Added support for public key authentication in the connection
6637 authentication protocol in the client library. Affected file
6638 lib/silcclient/protocol.c.
6640 * Changed the server's silc_idlist_get_clients_by_* interface
6641 to support already allocated array so that new entries may be
6642 added to pre-allocated array. Affected file silcd/idlist.[ch].
6643 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6644 and command replies.
6646 * All command reply functions in the server now calls the
6647 pending command callback even if error occured. This way the
6648 error will be delivered to the client as well. Affected files
6649 silcd/command.c and silcd/command_reply.c.
6651 * Fixed INFO command to return local server's info if no server
6652 was provided. Affected file lib/silcclient/command.c.
6654 * Removed RESTART command for good. Updated the code and the
6657 * Rewrote parts of the task system. It is a bit simpler now.
6658 Removed unsued task priorities. The affected files are
6659 lib/silcutil/silctask.[ch].
6661 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6663 * Moved the USERS printing from the library to the application.
6664 Affected files lib/silcclient/command.c and silc/client_ops.c.
6666 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6670 * Added channel key re-key support. The re-key is perfomed
6671 only by the router and is done once in an hour. Added `rekey'
6672 field to the SilcChannelEntry in the server. Affected files
6673 silcd/server.c and silcd/idlist.h.
6675 * Added silc_task_unregister_by_context into the file
6676 lib/silcutil/silctask.[ch].
6678 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6680 * Added SILC_UMODE_GONE mode to indicate when the client is not
6681 present in the SILC network. Added also support to the local
6682 command AWAY that will set this mode. Added support of showing
6683 "xxx is gone" in WHOIS command. The USERS command shows the
6684 gone status as well.
6686 * Fixed setting server and router operator privileges in the
6687 server's UMODE command. Affected file silcd/command.c.
6689 * Merged the SKE KE1 and KE2 payloads into one payload. The
6690 new KE payload is equivalent to the old KE2 payload.
6692 Cleaned up the SKE Start Payload parsing. It now uses the
6693 simple buffer unformatting to do the parsing. A lot faster
6696 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6697 to the SKE that is used to indicate whether both of the SKE
6698 parties should perform authentication. By default only the
6699 responder performs authentication. By setting this flag also
6700 the initiator must do authentication. By default it is unset
6701 since in normal SKE case, client to server connection, only
6702 the responder should do authentication. When doing SKE between
6703 two clients both should perform authentication. Updated the
6704 code and the protocol specs.
6706 * A little fix to IDENTIFY command in the server. Search the
6707 client first by hash not nickname. Affected file is
6710 * Fixed the silc_client_close_connection to support closing
6711 the client to client connections wihtout deleting too much
6712 data. Affected file lib/silcclient/client.c.
6714 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6715 are received if protocol used to be active but is not anymore
6716 the application would crash due to NULL pointer dereference.
6717 Affected files silcd/server.c and lib/silcclient/client.c.
6719 * Added `hash' field to the SilcClientConnection to include
6720 the hash function negotiated in the SKE protocol.
6722 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6723 to set the channel founder authentication data. A client can
6724 claim the founder rights later by providing the authentication
6725 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6726 This way the channel founder can regain the channel founder
6727 privileges even it is left the channel. This works only on
6728 local server and the client must be connected to the same
6729 server to be able to regain the founder rights. Updated the
6730 protocol specs accordingly.
6732 Added support to the CMODE command in the client to set the
6733 founder auth data. Read the README to see how to set it.
6735 Added support to the CUMODE command to claim the founder
6736 rights. Read the README to see how to do it.
6738 Added support for the founder authentication to the Channel
6739 Entry in the server. Affected file silcd/idlist.h.
6741 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6742 server's CMODE command. Affected file silcd/command.c.
6744 * Added the following new functions into lib/silccore/silcauth.[ch]:
6745 silc_auth_get_method and silc_auth_get_data.
6747 * The server now saves the remote hosts public key to the
6748 SilcIDListData pointer. Affected file silcd/protocol.c.
6750 * The normal server now does not remove the channel entry from
6751 the cache if the founder authentication data is set. It used
6752 to remove it if the founder was the last one on the channel on
6753 the server and left the channel. The auth data is saved and
6754 if the channel is re-joined later the old entry is used with
6755 the old auth data. Affected files silcd/command_reply.c and
6758 * Removed the `pkcs' field from the SilcIDListData structure
6759 in the server; it is not used. Affected file silcd/idlist.h.
6761 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6763 * Fixed packet processing on slow links. Partial packets were
6764 never re-processed because the incoming data buffer was cleared
6765 by the application. Application must not directly clear the
6766 sock->inbuf, the packet processing routines handle it. Fixed
6767 this in client library and in server.
6769 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6771 * Fixed the WHOIS and IDENTIFY send reply function to really
6772 check whether to send list or just one entry. Affected file
6775 * Cleaned up the LEAVE command's channel key distribution. The
6776 affected file silcd/command.c.
6778 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6779 can enforce the channel mode as well. In that case the ID
6780 includes the ID of the server. The code now enforces the
6781 mode change if the router have different mode than the server.
6783 * The notify client operation with CMODE_CHANGE notify can now
6784 return NULL client_entry pointer if the CMODE was not changed
6785 by client. Application must check for this.
6787 * Added <Server ID> argument to INFO command to support server
6788 info fetching by Server ID.
6790 * Added silc_server_announce_get_channel_users to get assembled
6791 packets of channel users of the specified channel. Affected
6792 file silcd/server.[ch].
6794 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6795 was freed underneath the ID Cache.
6797 * Re-announce clients when the server received CHANNEL_CHANGE
6798 notify from the router. Affected file silcd/packet_send.c.
6800 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6802 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6803 crashed since it did not handle the fact that there is no cipher
6804 called "3" and didn't check the error condition. Now fixed.
6806 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6807 flag. It can be used to send message requests.
6809 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6811 * Implemented the RESTART command in the client.
6813 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6814 notice type messages. Added notice printing to the user
6817 * The channel keys are not re-generated if the channel's mode
6818 is PRIVKEY, ie private key on the channel exists. Affected
6819 files silcd/server.c and silcd/command.c.
6821 * Fixed a little bug in channel message delivery when channel
6822 private keys are set in the server. Affected file is
6823 silcd/packet_send.c.
6825 * Changed the setting on channel->on_channel = TRUE from the
6826 silc_client_save_channel_key to the JOIN command reply. The
6827 key payload is not received if the private channel key is set.
6828 Affected file lib/silcclient/command_reply.c and the
6829 lib/silcclient/client_channel.c.
6831 * When the CMODE_CHANGE notify is sent and the channel private
6832 key mode is removed the channel key must be re-generated in
6833 other cells as well. Added this support for the router in the
6834 silcd/packet_receive.c.
6836 * Added new local command NOTICE to send notice message on
6837 channel. Affected file silc/local_command.[ch].
6839 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6841 * Added new local command ME to the client. It is used to send
6842 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6843 some action. Affected file silc/local_command.[ch].
6845 * Changed channel_message and private_message client operations
6846 to deliver the message flags to the application. Added also
6847 the `flags' arguments to the silc_client_send_channel_message
6848 and silc_client_send_private_message functions. Affected file
6851 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6853 * Redefined the Private Message Payload to support private message
6854 keys and to support the new private message flags. Updated
6855 the protocol specs. Flags makes it possible to have for example
6856 CTCP style messages.
6858 * Added new type SilcPrivateMessagePayload and defined an API
6859 for it in the lib/silcclient/silcprivate.[ch].
6861 * Tested private message private keys successfully. Tested the
6862 private message key set, unset and list commands with the new
6865 * Redefined the Channel Message Payload to include the channel
6866 message flags (equal with private message flags) to support
6867 for example CTCP style messages.
6869 * Defined some of the message (for channel and private message)
6870 flags. Updated the protocol specs and added the flags to the
6871 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6873 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6875 * Added SilcKeyAgreementStatus type to the key agreement routines
6876 to indicate the current status and error if one occured.
6877 The status types are defined in the lib/silcclient/silcapi.h.
6879 * Added new local command KEY that is used to set and unset private
6880 keys for channels, set and unset private keys for private messages
6881 with remote clients and to send key agreement requests and
6882 negotiate the key agreement protocol with remote client. The
6883 key agreement is supported only to negotiate private message keys,
6884 it currently cannot be used to negotiate private keys for channels,
6885 as it is not convenient for that purpose.
6887 * Fixed a minor pending callback setting bug in the function
6888 silc_client_get_client_by_id_resolve, now the function works.
6889 Affected file lib/silcclient/idlist.c.
6891 * Added function silc_net_get_local_port to get local bound
6892 port by socket. Added to lib/silcutil/silcnet.[ch].
6894 * Added `sockets' and `sockets_count' fields to the SilcClient
6895 object. They hold the sockets of the listenning sockets in
6896 the client. Listenning sockets may be for example the key
6897 agreement server. Affected file lib/silcclient/client.[ch].
6898 Added functions the silc_client_add_socket and the
6899 silc_client_del_socket. They are exported to the application
6902 * Added ~./silc/clientkeys to support other client's public keys.
6904 * Renamed verify_server_key client operation to verify_public_key
6905 and added one argument to indicate the type of the connection
6906 (server, client etc.).
6908 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6910 * Added silc_server_connection_auth_request to handle the
6911 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6912 silcd/packet_receive.[ch].
6914 * Added silc_server_send_connection_auth_request into the
6915 silcd/packet_send.c to send the connection auth request packet.
6917 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6920 * Fixed the public key authentication in responder side in the
6921 server. The `auth_data' pointer includes the SilcPublicKey
6922 not the path to the public key. Affected file silcd/protocol.c.
6924 * Implemented the public key authentication in the initiator side
6925 in the server. Affected file silcd/protocol.c.
6927 * Removed the [RedirectClient] config section from the server
6928 configuration. Is not needed and I don't want to implement it.
6930 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6932 * Cleaned up the CMODE command in the server. It now works
6933 correctly and supports all the modes defined in the protocol.
6934 Affected file is silcd/command.c.
6936 * Added `hmac_name' field to the SilcChannelEntry in the server
6937 to hold the default HMAC of the channel. It can be set when
6938 creating the channel (with JOIN command). Affected files
6941 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6942 type to indicate the change of the current cipher and hmac
6943 on the channel. Client can safely ignore the <cipher> argument
6944 (if it chooses to do so) since the CHANNEL_KEY packet will
6945 force the channel key change anyway. The <hmac> argument is
6946 important since the client is responsible of setting the new
6947 HMAC and the hmac key into use.
6949 * Fixed the CMODE command in the client library as well.
6951 * Tested CMODE command in router environment successfully.
6953 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6955 * Show the version of the remote client (or server) when connecting
6956 to the server. It is logged to the log file. Affected file
6957 is silcd/protocol.c.
6959 * Fixed the KILLED notify handling in the client library. The
6960 client must be removed from all channels when receiving the
6963 Also, do not remove the client entry when giving the KILL
6964 command but when the KILLED notify is received.
6966 * Removed silc_idlist_find_client_by_nickname from the server.
6967 Not needed anymore. Affected files silcd/idlist.[ch].
6969 * Implemented the CHANNEL_CHANGE notify type handling to the
6970 server. Affected file silcd/server.c.
6974 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6976 * Added silc_server_send_notify_invite to send the INVITE
6977 notify between routers.
6979 * Implemented the INVITE command correctly to the server.
6981 * Implemented the INVITE notify type handling in the server.
6983 * Implemented the INVITE command to the client library and on the
6986 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6988 * Added function silc_server_get_client_resolve to find the
6989 client entry by ID from all ID lists and then resolve it
6990 (using WHOIS) if it cannot be found. Affected file is
6993 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6995 * Implemented the BAN command to the client library.
6997 * The JOIN command in the server now checks the invite list
7000 * Changed the silc_command_reply_payload_encode_va and the
7001 silc_command_payload_encode_va to support that if argument is
7002 NULL it ignores and checks the next argument. Affected file
7003 lib/silccore/silccommand.c.
7005 * Added silc_server_send_notify_ban to send the BAN notify
7006 type between routers.
7008 * Chaned the silc_notify_payload_encode to support that if
7009 argument is NULL it ignores and checks the next argument.
7010 Affected file lib/silccore/silcnotify.c.
7012 * Tested ban lists in router environment successfully.
7014 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7016 * Implemented BAN command to the server, in silcd/command.[ch].
7018 * Removed the BAN and INVITE_LIST modes from the CMODE command
7021 * Added function silc_string_match to regex match two strings.
7022 Affected files lib/silcutil/silcutil.[ch].
7024 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7026 * Redefined parts of the SilcChannelEntry in the server to support
7027 the new ban and invite lists.
7029 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7031 * Redefined the INVITE command. The same command can be used to
7032 invite individuals to the channel but also to manage the invite
7033 list of the channel (to add to and remove from the invite list).
7034 Updated the protocol specs.
7036 * Added new command SILC_COMMAND_BAN that can be used to manage
7037 the ban list of the channel. Updated the protocol specs.
7039 * Removed the channel modes: the SILC_CMODE_BAN and the
7040 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
7041 in the CMODE command. The equivalent features are now available
7042 using INVITE and BAN commands. Updated the protocol specs.
7044 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
7045 in the network about change in the current ban list. The notify
7046 type is not used by the client.
7048 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
7049 support the invite lists.
7051 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7053 * Added new function silc_string_regexify that converts string
7054 including wildcard characters into regex string that can
7055 be used by the GNU regex library. Added into the file
7056 lib/silcutil/silcutil.[ch].
7058 Added silc_string_regex_combine to combine to regex strings
7059 into one so that they can be used as one regex string by
7060 the GNU regex library. Added into the file
7061 lib/silcutil/silcutil.[ch].
7063 Added silc_string_regex_match to match two strings. It returns
7064 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
7066 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7068 * Imported GNU regex to the soruce tree into lib/contrib.
7069 Fixed some compiler warning from the regex.c.
7071 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7073 * Fixed MOTD command in the server to work in router environment.
7075 * Fixed the MOTD command in the client library to support
7076 the server argument in the command.
7078 * Added `nickname_len' argument to the silc_idlist_add_client
7079 in the server, as the `nickname' argument may be binary data
7082 * Added silc_idlist_get_channels to return all channels from
7085 * Implemented LIST command to the server. Affected file is
7088 * Implemented the LIST command to the client library and on the
7091 * Added [<user count>] argument to the LIST command reply.
7092 With private channels the user count is not shown.
7094 * Updated TODO and README.
7096 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7098 * The client entry's data.registered must be TRUE even with
7099 global client entry on global client list. The data.registered
7100 is used to check whether the client is anymore in the network,
7101 for example with WHOWAS command so it must be valid.
7103 * Fixed the WHOWAS command in the server. It now actually works
7104 in router environment. Added function into silcd/command_reply.c
7105 silc_server_command_reply_whowas_save.
7107 * Added silc_idlist_purge function to the silcd/idlist.c
7108 to periodically purge the ID Cache.
7110 * Fixed INFO command in the server. It works now in router
7111 environment. Added <server name> argument to the INFO command
7112 reply. Updated the protocol specs.
7114 * Fixed minor bug in silc_idcache_purge to not purge if the
7115 expire value is zero.
7117 * Fixed various bugs in WHOIS and IDENTIFY command handling as
7118 they were buggy because of the WHOWAS information.
7120 * Fixed local command MSG to handle the async resolving of
7121 the remote client properly. It used to fail the first MSG.
7122 Affected file silc/local_command.c.
7124 * Added `data_len' field to SilcIDCache context.
7126 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7128 * Update TODO. Todo in commands in the server.
7130 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7132 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
7133 used by routers as broadcast packet to inform other routers
7134 about the changed user mode.
7136 Implemented the notify handling in the server. Affected file is
7137 silcd/packet_receive.c. Added the function
7138 silc_server_send_notify_umode to the silcd/packet_send.[ch].
7140 * Added new generic Channel Payload and deprecated the New Channel
7141 Payload. The New Channel Payload is now the generic Channel
7144 * Added new argument `mode' to the silc_server_send_new_channel
7145 as it is required in the Channel Payload now.
7147 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
7148 and created a new and real SilChannelPayload to represent the
7149 new generic Channel Payload. Implemented the encode/decode
7150 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
7152 * Added silc_server_get_client_channel_list to return the list
7153 of channels the client has joined for WHOIS command reply.
7154 Affected file silcd/server.[ch].
7156 * Implemented the channel list sending in the WHOIS command reply
7157 in server and in the client.
7159 Implemented the channel list displaying on the user interface
7160 as well. Affected file silc/client_ops.c.
7162 * Added silc_channel_payload_parse_list to parse list of Channel
7163 Payloads. It returns SilcDList list of SilcChannelPayloads.
7164 Client for example can use this function to parse the list of
7165 channels it receives in the WHOIS command reply. The caller
7166 must free the list by calling silc_channel_payload_list_free.
7167 Affected files lib/silccore/silcchannel.[ch].
7169 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7171 * Added one new argument <user mode> to the WHOIS command reply
7172 to return the mode of the user in SILC. Updated the protocol
7175 Implemented it to the server and client.
7177 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7179 * Fixed the mode printing on the user interface on joining.
7180 Affected file silc/client_ops.c.
7182 * Implemented the UMODE command and user modes in general to the
7183 client library and to the user interface.
7185 * Implemented the UMODE command to the server.
7187 * The server now sends UNKNOWN_COMMAND error status if client sends
7188 unknown command. Affected file silcd/command.c.
7190 * All server commands now handle the command identifier the right
7191 way when sending the command reply to the client. The client can
7192 use to identify the command replies with the identifier.
7194 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7196 * Added silc_server_get_client_route to resolve the route to
7197 the client indicated by the client ID. Affected file is
7200 * Added silc_server_relay_packet as general function to relay
7201 packet to arbitrary destination. This deprecates functions
7202 like _send_private_message_key, _relay_notify etc. Affected
7203 file is silcd/packet_send.[ch].
7205 Removed silc_server_send_key_agreement,
7206 silc_server_send_private_message_key and
7207 silc_server_packet_relay_notify functions from the file
7208 silcd/packet_send.[ch].
7212 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
7213 server. Affected file silcd/packet_receive.[ch].
7215 * Implemented the KILL command to the client. Implemented the
7216 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
7217 Affected files lib/silcclient/command[_reply].c and
7218 lib/silcclient/client_notify.c. Implemented the KILL notify
7219 printing in the user inteface.
7221 * Fixed a lot silc_parse_nick memory leaks from the client
7222 library in the file lib/silcclient/command.c.
7224 * Changed the silc_server_send_notify_on_channels's `sender'
7225 argument from SilcSocketConnection to SilcClientEntry to
7226 check the sender as entry and not as connection object and not
7227 to send to the client provided as argument. The affected file
7228 is silcd/packet_send.[ch].
7230 * The notify packets that are destined directly to the client used
7231 to not to be processed by the server. Now changed that and the
7232 server processes all notify packets. After relaying the packet
7233 to the client the notify packet is processed in the server.
7235 * The silc_server_free_client_data now checks whether there is
7236 pending outgoing traffic for the client and purges the data to
7237 the network before removing the client entry.
7239 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7241 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
7242 an client is killed from the SILC Network. Updated the protocol
7245 Added new function silc_server_send_notify_killed to the
7246 silcd/packet_send.[ch].
7248 * Added function silc_server_packet_relay_notify to relay notify
7249 packets that are destined directly to a client. In this case
7250 the server does not process the notify packets but merely relays
7251 it to the client. Affected file silcd/packet_send.[ch].
7253 Added also silc_server_packet_process_relay_notify to check
7254 whereto relay the notify. Affected file is
7255 silcd/packet_receive.[ch].
7257 * Implemented the KILL command to the server.
7261 * Added the backup schema desgined last fall to the protocol
7262 specs for everyone to see. The specification is in the
7263 *-spec-xx.txt draft and the packet type definitions for the
7264 backup routers is in *-pp-xx.txt draft. Thusly, added also
7265 new packet type SILC_PACKET_CELL_ROUTERS.
7267 * A big security problem in the implementation discovered. The
7268 signoff of an client did not cause new channel key generation
7269 which it of course should've done. The channel keys must be
7270 always re-generated when client leaves (or signoffs) the channel.
7271 The silc_server_remove_from_channels funtion now handles
7272 the channel key re-generation.
7274 * Added `sender' argument to the silc_server_send_notify_on_channels
7275 to not to send the client provided as argument. Affected file
7276 silcd/packet_send.[ch].
7278 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7280 * Implemented OPER and SILCOPER commands into the server and
7283 * Added silc_auth_verify and silc_auth_verify_data to verify
7284 the authentication directly from the authentication payload.
7285 It supports verifying both passphrase and public key based
7286 authentication. Affected file lib/silccore/silcauth.[ch].
7288 * Added `hash' field to the SilcIDListData structure. It is the
7289 hash negotiated in the SKE protocol. Affected file is
7292 * Slight redesigning of the SilcAuthPayload handling routines.
7293 Do not send SilcPKCS but SilcPublicKey as argument.
7295 * Implemented the public key authentication support to the
7296 serverconfig. The public key is loaded from the provided path
7297 and saved as authentication data to void * pointer. Thus,
7298 changed the unsigned char *auth_data to void *auth_data;
7300 * Fixed SHUTDOWN command to send the reply before the server
7301 is shutdown. :) Affected file silcd/command.c.
7303 * Fixed fatal bug in CONNECT command. The hostname was invalid
7304 memory and server crashed. Affected file silcd/command.c.
7306 * Fixed fatal bug in CLOSE command. The server_entry became
7307 invalid but was referenced later in the command. Affected file
7310 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7312 * Fixed fatal bug in failure packet handling. Server ignored
7313 the failure and thus crashed when it came.
7317 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7319 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
7320 that the command may be executed only once in (about) 2 seconds.
7321 The old SILC_CF_LAG flag is same but allows command bursts up
7322 to five before limiting.
7324 Added the support for CF_LAG and CF_LAG_STRICT flags to the
7325 server code. Various commands now includes the CF_LAG_STRICT
7326 flag to disallow any kind of miss-use of the command.
7328 * Fixed the silc_buffer_unformat to not to allocate any data
7329 if the length of the data is zero. It used to allocate the
7330 length + 1. Affected file lib/silcutil/silcbuffmt.c.
7332 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7334 * Changed the format of AdminConnection configuration section
7335 in the server. Added username of the admin to the format.
7336 Affected files silcd/serverconfig.[ch].
7338 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
7339 to return admin configuration data by host, username and/or
7342 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7344 * Implemented WHOWAS command to the server. Added the functions:
7346 silc_server_command_whowas_parse,
7347 silc_server_command_whowas_send_reply,
7348 silc_server_command_whowas_from_client and
7349 silc_server_command_whowas_from_server
7351 * Added <Client ID> argument to the WHOWAS command reply. Updated
7352 the protocol specs accordingly.
7354 * Implemented WHOWAS command and command_reply to the client
7357 Implemented the WHOWAS printing on the user interface.
7359 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7361 * Added new argument to the WHOWAS command reply, the real name.
7362 It is an optional argument. Updated the protocol specs.
7364 * Added SilcIDCacheDestructor callback that is registered when
7365 the SilcIDCache is allocated. The callback is called when
7366 an cache entry in the ID Cache expires, or is purged from the
7367 cache. Added into lib/silccore/idcache.[ch].
7369 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
7370 to destruct the client entries when the cache entry expires.
7371 Other ID Cache's in server and in the client library ignores
7374 * If the ID Cache entry's `expire' field is zero then the entry
7375 never expires. Added boolean `expire' argument to the
7376 silc_idcache_add function in the lib/silccore/idcache.[ch].
7377 If it is TRUE the default expiry value is used.
7379 * Added silc_server_free_client_data_timeout that is registered
7380 when client disconnects. By default for 5 minutes we preserve
7381 the client entry for history - for WHOWAS command.
7383 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7385 * Added support to the server to enforce that commands are not
7386 executed more than once in 2 seconds. If server receives
7387 commands from client more frequently, timeout is registered
7388 to process the commands. Affected file silcd/command.c.
7389 Added new function silc_server_command_process_timeout.
7391 * Changed NICK_NOTIFY handling in client library to check that
7392 if the client's nickname was changed, so there is no need to
7393 resolve anything from the server.
7395 * Removed error printing from the WHOIS and IDENTIFY commands.
7396 If error occurs then it is ignored silently in the client library.
7397 The application, however, may map the received error to
7398 human readable error string. The application currently maps
7399 the NO_SUCH_NICKNAME error to string.
7401 * Made the command status message public to the application. Moved
7402 them from lib/silcclient/command_reply.c to
7403 lib/silcclient/command_reply.h. The application can map the
7404 received command status to the string with the
7405 silc_client_command_status_message function.
7407 * Added check to the server to check that client's ID is same
7408 as the Source ID in the packet the client sent. They must
7411 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7413 * Added dist-bzip hook to the Makefile.am to make bzip2
7414 compressed distributions.
7416 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7418 * Server now enforces the maximum length for the nickname and
7419 the channel as protocol specification dictates. 128 bytes for
7420 nickname and 256 bytes for channel name.
7422 * Moved the WHOIS printing to the application. The client libary
7423 does not print out the WHOIS information anymore, the application
7424 must do it. Renamed silc_client_command_reply_whois_print to
7425 the silc_client_command_reply_whois_save.
7427 The client's idle time is also sent to the application now, and
7428 the idle is shown on screen.
7430 * Added silc_client_command_reply_identify_save to save the
7431 received IDENTIFY entries.
7433 * Do not check for channel private keys in message sending and
7434 reception if the channel does not have the PRIVKEY mode set.
7435 Affected file lib/silclient/client_channel.c.
7437 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7439 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
7440 just surfaced after chaning the JOIN procedure.
7442 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7444 * Added silc_client_get_clients_by_list to get client entries
7445 from Client ID list, that is returned for example by JOIN
7446 and USERS command replies. The application should use this
7447 function for example when JOIN command reply is received to
7448 resolve the clients already on the channel (library does not
7449 do that anymore as USERS command reply is not used in the JOIN
7450 procedure anymore). Affected files lib/silcclient/silcapi.h and
7451 lib/silcclient/idlist.c.
7453 * JOIN command reply and USERS command reply returns now SilcBuffer
7454 pointers instead of unsigned char pointers when returning
7455 the client list and mode list.
7457 * Added <Client ID> argument to the JOIN command reply, mainly
7458 for the server to identify for which client the command was
7459 originally sent. Updated protocol specs accordingly.
7461 * Added SilcDlist private_key pointer to the SilcChannelEntry
7462 in the client to support the channel private keys. Affected
7463 file is lib/silcclient/idlist.h.
7465 * Added SilcChannelPrivateKey argument to the function
7466 silc_client_send_channel_message so that application can choose
7467 to use specific private ke if it wants to. If it is not provided,
7468 the normal channel key is used, unless private keys are set.
7469 In this case the first (key that was added first) is used
7470 as the encryption key.
7472 * Implemented the support for channel private key handling.
7473 Implemented the following functions:
7475 silc_client_add_channel_private_key,
7476 silc_client_del_channel_private_keys,
7477 silc_client_del_channel_private_key,
7478 silc_client_list_channel_private_keys and
7479 silc_client_free_channel_private_keys
7481 Affected file lib/silcclient/client_channel.c.
7483 * Added the support for the private keys in the channel message
7484 sending and encryption and in the message reception and
7485 decryption. Affected funtions are
7486 silc_client_send_channel_message and silc_client_channel_message.
7488 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7490 * Added SKE's key verify callback to the client library's
7491 KE protocol context. Affected files lib/silcclient/protocol.[ch].
7493 * Removed the statement that server (or router) must send USERS
7494 command reply when joining to the channel so that the client
7495 knows who are on the channel. Instead, the client list and
7496 client's mode list is now sent in the JOIN command reply to the
7497 client who joined channel. This is better solution.
7499 * Added function silc_server_get_users_on_channel and function
7500 silc_server_save_users_on_channel to the silcd/server.[ch].
7502 * Removed function silc_server_command_send_users from the
7505 * Do not show topic on the client library anymore. The topic is
7506 sent in the command reply notify to the application and the
7507 application must show the topic now.
7509 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7511 * Added client searching by nickname hash into the IDENTIFY and
7512 WHOIS commands in the server as they were clearly missing from
7513 them. Affected file is silcd/command.c.
7515 * Fixed a bug in private message receiving in the client library.
7516 The remote ID was freed and it wasn't supposed, now it is
7519 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7521 * Minor fix to the channel payload; allocate the data area, as it
7522 needs to be of specific length.
7524 * If the key agreement port is zero then the operating
7525 system will define the bound port. Affected files are
7526 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7528 * Added new function silc_channel_payload_decrypt into the file
7529 lib/silccore/silcchannel.[ch].
7531 * Moved the channel message etc, check from silc_packet_decrypt
7532 to applications. The library calls now a generic
7533 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7534 when the packet is either normal or special. This was done to
7535 allow more wide range of checking that was not allowed when
7536 the code was in library. Now applications can do virtually any
7537 checks to the packet and return to the library the decision how
7538 the packet should be processed. Affected files are
7539 lib/silccore/silcpacket.[ch].
7541 Added silc_server_packet_decrypt_check to the server and
7542 silc_client_packet_decrypt_check to the client library.
7544 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7545 to send with specified source and destination information.
7547 * Channel message delivery between routers was broken after the
7548 channel key distribution was fixed earlier. The channel key
7549 was used be to distributed to other routers as well which is not
7550 allowed by the protocol. Now this is fixed and channel keys
7551 really are cell specific and the channel message delivery between
7552 routers comply with the protocol specification.
7554 * Fixed various commands in server to check also the global list
7555 for the channel entry and not just the local list. The affected
7556 file silcd/command.c.
7558 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7560 * Added assert()s to buffer formatting and unformatting routines
7561 to assert (if --enable-debug) when error occurs. Affected
7562 file: lib/silcutil/silcbuffmt.c.
7564 * Changed to auto-reconnect to check whether the remote host is
7565 router and register the re-connect timeout if it is. It used
7566 to check that whether we are normal server, but router must do
7567 auto-reconnect with another router as well. Affected file
7570 * Removed the [<key len>] option from CMODE command as the cipher
7571 name decides the key length, nowadays. See the defined ciphers
7572 from the protocol specification.
7574 * Added [<hmac>] option to the CMODE command to define the HMAC
7575 for the channel. Added SILC_CMODE_HMAC channel mode.
7577 * Added [<hmac>] option for the JOIN command so that user can
7578 select which HMAC is used to compute the MACs of the channel
7581 * Added Hmac field to the Channel Message Payload. The integrity
7582 of plaintext channel messages are now protected by computing
7583 MAC of the message and attaching the MAC to the payload. The
7584 MAC is encrypted. Now, it is clear that this causes some
7585 overhead to the size of the packet but rationale for this is that
7586 now the receiver can verify whether the channel message decrypted
7587 correctly and also when private keys are set for the channel the
7588 receiver can decrypt the packet with several keys and check from
7589 the MAC which key decrypted the message correctly.
7591 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7592 lib/silccrypt/silccipher.[ch].
7594 * Added silc_hash_len to return the digest length into the
7595 lib/silcrypt/silchash.[ch].
7597 * Rewrote parts of Silc Channel Payload interface in the
7598 lib/silccore/silcchannel.[ch]. The encode function now also
7599 encrypts the packet and parse function decrypts it.
7601 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7603 * Fixed a minor formatting bug in the SKE's key material processing.
7604 It actually might have processed the keys wrong way resulting
7607 * Redefined the mandatory HMAC algorithms and added new algorithms.
7608 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7609 and hmac-md5 truncated to 96 bits. The mandatory is now
7610 hmac-sha1-96. Rest are optional (including the one that used
7611 to be mandatory). Rationale for this is that the truncated HMAC
7612 length is sufficient from security point of view and can actually
7613 make the attack against the HMAC harder. Also, the truncated
7614 HMAC causes less overhead to the packets. See the RFC2104 for
7617 * Added new [hmac] configuration section. The SKE used to use
7618 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7619 is of course wrong. The official names that must be proposed in
7620 the SKE are the ones defined in the protocol specification
7621 (hmac-sha1-96 for example). The user can configure any hmac
7622 using any hash function configured in the [hash] section. At
7623 least, the mandatory must be configured.
7625 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7627 * Added HMAC list to the SKE proposal list. It has now both
7628 hash algorithm list and HMAC list. This makes the protocol
7629 incompatible with previous versions. The SKE now seems to work
7630 the way it is supposed to work, for the first time actually.
7632 * Defined plain Hash algorithms to the protocol specification.
7635 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7637 * Implemented support for key agreement packets into the server.
7638 Added functions silc_server_key_agreement and
7639 silc_server_send_key_agreement. Other than these functions,
7640 server has nothing to do with this packet.
7642 * Added support for private message key packets into the server.
7643 Added functions silc_server_private_message_key and
7644 silc_server_send_private_message_key.
7648 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7649 called in the protocol's final callback instead in the END
7650 protocol state. This makes a little more sense and in the same
7651 time in client we can use the same protocol routines for normal
7652 key exchange and to key agreement packet handling as well.
7654 * Added to both client's and server's KE protocol context the
7655 SilcSKEKeyMaterial pointer to save the key material. We will
7656 bring the key material to the protocol's final callback by doing
7657 this. The final callback must free the key material.
7659 * Added SKE's packet_send callback into client's KE protocol
7660 context so that the caller can choose what packet sending function
7661 is used. This way we can use different packet sending when
7662 doing normal SKE when doing key agreement packet handling (in
7663 the key agreement packet handling we do not want to encrypt
7666 * Implemented the responder side of the key agreement routines
7667 in the client. The client can now bind to specified port and
7668 accept incoming key negotiation. The key material is passed
7669 to the application after the protocol is over.
7671 * Implemented the processing of incoming Key Agreement packet
7672 in the client. Added function silc_client_key_agreement to
7675 * Implemented the intiator side of the key agreement routines
7676 in the client. The client can now initiate key agreement with
7677 another remote client. The key material is passed to the
7678 application after the protocol is over.
7680 * Created client_keyagr.c to include all the key agreement
7683 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7684 SILC_TASK_CALLBACK except that it is not static.
7686 * Created client_notify.c and moved the Notify packet handling
7687 from the client.[ch] into that file.
7689 * Created client_prvmsg.c and moved all private message and
7690 private message key routines from the client.[ch] into that file.
7692 * Create client_channel.c and moved all channel message and
7693 channel private key routines from the client.[ch] into that file.
7695 * Changed silc_client_get_client_by_id_resolve to resolve with
7696 WHOIS command instead of IDENTIFY command, in the file
7697 lib/silclient/idlist.c.
7699 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7701 * Implemented the SKE's responder side to the Client library.
7703 * When FAILURE is received to the protocol do not trust it
7704 blindly. Register a timeout to wait whether the remote closes
7705 the connection as it should do it, only after that process the
7706 actual failure. This was changed to both client and server.
7708 * Added client_internal.h to include some of the structures
7709 there instead of client.h in lib/silcclient/.
7711 * Added function silc_task_unregister_by_callback to unregister
7712 timeouts by the callback function.
7714 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7716 * Some "Incomplete WHOIS info" errors has been appearing on the
7717 log files. Took away the entry->userinfo check from WHOIS
7718 reply sending. The entry->userinfo is now " " if client did not
7719 provide one. I thought this was fixed earlier but something
7720 is wrong still. Let's see if the error still appears.
7722 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7724 * Fixed a minor bug in the login when the channel key is
7725 re-generated in the server. It used to generate the key in
7726 wrong order and thus caused problems in the channel traffic.
7728 * Fixed a minor bug in channel key distsribution after
7729 KICK command. The key was not sent to the router even though
7732 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7734 * Added silc_ske_process_key_material_data as generic routine
7735 to process any key material as the SILC protocol dictates. The
7736 function is used by the actual SKE library but can be used by
7737 applications as well. This relates to the private message keys
7738 and the channel private keys since they must be processed the
7739 same way the normal SILC session keys. The protocol dictates
7740 this. Affected files: lib/silcske/silcske.[ch].
7742 Added also silc_ske_free_key_material to free the
7743 SilcSKEKeyMaterial structure.
7745 * Defined silc_cipher_set_key function to set the key for
7746 cipher without using the object's method function. The affected
7747 files: lib/silccrypt/silccipher.[ch].
7749 * Implemented silc silc_client_add_private_message_key,
7750 silc_client_add_private_message_key_ske,
7751 silc_client_del_private_message_key,
7752 silc_client_list_private_message_keys and
7753 silc_client_free_private_message_keys functions in the
7756 Added functions silc_client_send_private_message_key to send
7757 the Private Message Key payload and silc_client_private_message_key
7758 to handle incoming Private Message Key payload.
7760 * Added Cipher field to the Private Message Key payload to set
7761 the cipher to be used. If ignored, the default cipher defined
7762 in the SILC protocol (aes-256-cbc) is used.
7764 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7766 * Removed lib/silcclient/ops.h file.
7768 Redefined parts of the SILC Client Library API. Created new
7769 file silcapi.h that deprecates the ops.h file and defines the
7770 published Client Library API. Defined also private message key
7771 API and channel private key API into the file.
7773 This is the file that the application must include from the
7774 SILC Client Library. Other files need not be included by
7775 the application anymore.
7777 * Added new key_agreement client operation callback and also
7778 defined the Key Agreement library API for the application.
7780 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7782 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7783 is used by clients to request key negotiation between another
7784 client in the SILC network. If the negotiation is started it
7785 is performed using the SKE protocol. The result of the
7786 negotiation, the secret key material, can be used for example
7787 as private message key.
7789 Implemented the Key Agreement payload into the files
7790 lib/silccore/silauth.[ch].
7792 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7794 * Redefined ciphers for the SILC protocol. Added some new ciphers
7795 and defined the key lengths for the algorithms. Changed the
7796 code accordingly. The default key length is now 256 bits.
7798 * Fixed SKE key distribution function silc_ske_process_key_material
7799 when the key length is more than 128 bits. The default key
7800 length in SILC is now 256 bits.
7802 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7803 to indicate unsupported algorithm.
7805 * Renamed rijndael.c to aes.c and all functions as well.
7807 * Fixed a long standing channel key setting bug in client library.
7808 Weird that it has never surfaced before.
7810 * Fixed bug in channel deletion. If the entire channel is removed
7811 then it must also delete the references of the channel entry
7812 from the client's channel list as the client's channel entry and
7813 the channel's client entry share same memory.
7815 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7817 * Implemented CONNECT and SHUTDOWN commands in the client.
7819 * Implemented CLOSE command to the client.
7821 * Added the function silc_idlist_find_server_by_name into the
7822 files silcd/idlist.[ch].
7824 Added the function silc_idlist_find_server_by_conn into the
7825 files silcd/idlist.[ch].
7827 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7829 * DIE command was renamed to SHUTDOWN. Updated the both code
7832 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7833 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7835 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7838 * Added function silc_server_create_connection function to create
7839 connection to remote router. My server implementation actually
7840 does not allow router to connect to normal server (it expects
7841 that normal server always initiates the connection to the router)
7842 so the CONNECT command is only good for connecting to another
7845 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7847 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7848 or some other client was kicked from the channel.
7850 Implemented the handling of the notify type to both client
7853 Implemented silc_server_send_notify_kicked to send the KICKED
7854 notify. It is used to send it to the server's primary router.
7856 * Implemented the KICK command into server and client.
7858 * Added `query' argument to the silc_idlist_get_client function
7859 to indicate whether to query the client from server or not if
7862 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7863 to indicate that the client is not channel founder.
7867 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7869 * Removed the rng context from SilcPacketContext structure and
7870 changed that the packet routine uses the Global RNG API.
7872 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7874 * Added support for quit message that client can "leave" on the
7875 channel when it quits the SILC. It is ditributed inside the
7876 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7878 Added silc_server_free_client_data that will take the
7879 signoff message as argument.
7881 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7883 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7885 * Updated parts of the protocol specification to keep it up
7888 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7890 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7891 payloads in one packet.
7893 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7894 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7895 use now the new List flag.
7897 * Also deprecated the following packet types: REPLACE_ID,
7898 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7900 * Added list support for Notify packet in server.
7902 * Added silc_server_send_notify_channel_change to send the
7903 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7904 the silc_server_send_replace_id.
7906 * Added silc_server_send_notify_nick_change to send the
7907 NICK_CHANGE notify type. Deprecates the function
7908 silc_server_send_replace_id.
7910 * Added silc_server_send_notify_join to send the JOIN notify type.
7911 Deprecates the function silc_server_send_new_channel_user.
7913 * Added silc_server_send_notify_leave to send LEAVE notify type.
7914 Deprecates the function silc_server_send_remove_channel_user.
7916 * Added silc_server_send_notify_cmode and
7917 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7918 types. Deprecates the silc_server_send_set_mode function.
7920 * Added SERVER_SIGNOFF notify type to indicate that server has
7921 quit. This means that all clients on the channel from that
7922 server will drop. This can be also used when netsplit happens.
7924 Deprecated REMOVE_ID packet type since it is not needed anymore
7927 Added silc_server_send_notify_server_signoff to send the
7928 SERVER_SIGNOFF notify type. Deprecates the function
7929 silc_server_send_remove_id.
7931 Added also silc_server_send_notify_signoff to send the
7932 SIGNOFF notify type.
7934 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7935 SILC protocol from this day on. Changed the protocol
7936 specification as well.
7938 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7939 notify type. It is used between routers to notify about
7940 topic changes on a channel.
7942 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7945 * Partly updated the protocol specification to comply with the
7946 changes now made. It is still though a bit outdated.
7948 * The JOIN notify type now takes one extra argument <Channel ID>.
7949 The packet used to be destined to the channel but now the
7950 JOIN type may be sent as list thus it is impossible to
7951 destine it to any specific channel. By adding this argument
7952 it is again possible.
7954 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7956 * Added CREDITS file. The CHANGES and CREDITS file will appear
7957 in the distribution as well.
7959 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7961 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7962 types in the server's silcd/packet_receive.c.
7964 * Implemented CMODE and CUMODE to work in router environment.
7966 * Fixed minor encoding and decoding buglet from the
7967 lib/silccore/silcmode.c.
7969 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7972 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7974 * Changed all SilcConfigServer* and silc_config_server* to
7975 SilcServerConfig* and silc_server_config*, respectively.
7978 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7980 * Associated the ID (client or server ID) to the Authentication
7981 Payload to avoid any possibility of forging. Updated the
7982 protocol specification and the code accordingly.
7984 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7986 * The RSA key length is now save to the RsaKey context in the
7987 key generation process in lib/silccrypt/rsa.c. The key length
7988 is now used to figure out the maximum size of the block allowed
7989 to be encrypted/signed.
7991 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7992 is equivalent to the silc_mp_mp2bin but does not allocate any
7995 * Changed silc_mp_mp2bin API to take length argument. If it is
7996 non-zero then the buffer is allocated that large. If zero, then
7997 the size is approximated using silc_mp_sizeinbase, which however
8000 * Created Global RNG API which is global RNG that application can
8001 initialize. After initializing, any routine anywhere in the
8002 code (including library) can use RNG without allocating a new
8003 RNG object. This was done to allow this sort of use of the
8004 RNG in code that has no chance to allocate RNG object. All
8005 applications currently allocate this and many routines in the
8006 library use this. Affected file lib/silccrypt/silcrng.[ch].
8008 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
8009 it to use the Global RNG API.
8011 * Defined Authentication Payload into protocol specification that
8012 is used during SILC session to authenticate entities. It is
8013 used for example by client to authenticate itself to the server
8014 to obtain server operator privileges.
8016 Implemented this payload into the lib/silccore/silcauth.[ch].
8017 Implemented also routines for public key based authentication
8018 as the new protocol specification dictates.
8020 Moved definitions of different authentication methods from
8021 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
8023 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
8024 silc_pkcs_verify and silc_pkcs_sign_with_hash and
8025 silc_pkcs_verify_with_hash functions into the file
8026 lib/silccrypt/silcpkcs.[ch].
8028 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8030 * The client entry's userinfo pointer must be always valid.
8031 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
8032 will fail since it requires the userinfo. Now, the userinfo
8033 is allocated as "" if actual userinfo does not exist. Actually,
8034 it must exist and it is totally Ok to drop client connections
8035 that does not announce the userinfo. However, we will make
8036 this workaround for now.
8038 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
8039 to return the remote port by socket.
8041 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8043 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
8044 SILC_SERVER_PENDING_EXEC and added an new macro
8045 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
8046 data or when error occurs while processing the pending command.
8048 Added new argument `destructor' into silc_server_command_pending
8049 and to the SilcServerCommandPending object. This destructor is
8050 now called after calling the pending callback or if error occurs
8051 immediately. If error occurs the actual pending callback won't
8052 be called at all - only the destructor. The destructor may be
8053 NULL if destructor is not needed.
8055 All this applies for client library code as well. Similar
8056 changes were made there as well for the pending commands.
8058 In the client, the application must now allocate the
8059 SilcClientCommandContext with the silc_client_command_alloc
8062 * Added reference counter to the SilcServerCommandContext. Added
8063 function silc_server_command_alloc and silc_server_command_dup
8066 Same type of functions added to the client library for the same
8069 * Removed the cmd_ident from IDListData away since it is now
8070 global for all connections. It is the command identifier used
8071 in command sending and with pending commands. The affected file
8074 * Added reference counter to the SilcSocketConnection objecet to
8075 indicate the usage count of the object. The object won't be
8076 freed untill the reference counter hits zero. Currently only
8077 server uses this, and client ignores it. The client must be
8078 set to use this too later. The affected files are
8079 lib/silccore/silcsockconn.[ch]. Added also the function
8080 silc_socket_dup to increase the reference counter.
8082 This was mainly added because it is possible that the socket
8083 is removed underneath of pending command or other async
8084 operation. Now it won't be free'd and proper DISCONNECTING
8085 flags, etc. can be set to avoid sending data to connection that
8086 is not valid anymore.
8088 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
8089 the connection. After that it sets SILC_SET_DISCONNECTED.
8090 It is, however, possible that the socket data is not still freed.
8091 The silc_server_packet_process now checks that data is not
8092 read or written to connection that is DISCONNECTED. The socket
8093 get's freed when the reference counter hits zero.
8095 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8097 * Changed the client operation API: channel_message operation's
8098 `sender' is now the client entry of the sender, not the nickname
8099 and the `channel' is the channel entry, not the channel name.
8101 In the private_message operation the `sender' is now also the
8102 client entry of the sender not the nickname.
8104 Affected file is lib/silcclient/ops.h and all applications
8105 using the client operations.
8107 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8109 * Moved the calling of ops->connect() from connect_to_server_final
8110 into receive_new_id functin since that is the point when the
8111 client is actually allowed to send traffic to network. The
8112 affected file is lib/silcclient/client.c.
8114 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8116 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
8117 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
8118 (if needs broadcasting) instead of broadcasting the packets one
8119 by one which would make a burst in the network traffic.
8121 * Added `broadcast' argument to the functions in silcd/server.[ch]
8122 silc_server_create_new_channel[_with_id] to indicate whether
8123 to send New Channel packet to primary router.
8125 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8127 * Added new function into the silcd/server.[ch] files:
8128 silc_server_create_new_channel_with_id to create new channel with
8129 already existing Channel ID.
8131 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
8132 lib/silccore/silcpacket.h. This packet is used t send list of
8133 Set Mode payloads inside one packet. Server uses this to set
8134 the modes for the channels and clients on those channels, that it
8135 announced to the router when it connected to it. The protocol
8136 specification has been updated accordingly.
8138 * The silc_server_new_channel did not handle the packet coming
8139 from normal server as it normally does not send that. However,
8140 when it announces its channels it does send it. Implemented
8141 the support for that.
8143 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
8144 into the file lib/silccore/id.h.
8146 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8148 * Fixed memory leaks in the functions silc_idlist_del_client,
8149 silc_idlist_del_channel and silc_idlist_del_server in the file
8150 silcd/idlist.c. All of those leaked like a sieve.
8152 * Fixed some small memory leaks in the client's function
8153 silc_client_notify_by_server.
8155 * Added functions into silcd/server.c: silc_server_announce_clients,
8156 silc_server_announce_channels and silc_server_announce_server.
8157 These functions are used by normal and router server to announce
8158 to its primary router about clients, channels and servers (when
8159 router) that we own. This is done after we've connected to the
8162 These functions effectively implements the following packet types:
8163 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
8164 and SILC_PACKET_NEW_ID_LIST.
8166 * Added new functions into the silcd/packet_receive.[ch]:
8167 silc_server_new_id_list, silc_server_new_channel_list and
8168 silc_server_new_channel_user_list to handle the incoming
8169 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
8171 * Added support of changing Channel ID in the function
8172 silc_server_replace_id. If the server that announces a channel
8173 to the router already exists in the router (with same name but
8174 with different Channel ID), router is responsible to send
8175 Replace ID packet to the server and force the server to change
8176 the Channel ID to the one router has.
8178 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
8179 client that the Channel ID has been changed by the router. The
8180 normal server sends this to the client. Client must start using
8181 the new Channel ID as the channel's ID.
8183 Implemented handling of this new type into lib/silcclient/client.c
8184 into the function silc_client_notify_by_server.
8186 * Added new function silc_idlist_replace_channel_id into the files
8187 silcd/idlist.[ch] to replace the Channel ID.
8189 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8191 * Call silc_server_command_identify_check always when processing
8192 the IDENTIFY command in silcd/command.c
8194 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8196 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
8197 send keepalive packets. The packet can be sent by clients,
8198 servers and routers.
8200 Added function silc_socket_set_heartbeat into the file
8201 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
8202 If not set, the heartbeat is not performed. The actual
8203 heartbeat is implemented in the low level socket connection
8204 library. However, application is responsible of actually
8207 Added silc_server_send_heartbeat to send the actual heartbeat
8208 packet into silcd/packet_send.[ch]. Server now performs
8209 keepalive with all connections.
8211 * Added silc_task_get_first function into lib/silcutil/silctask.c
8212 to return the timeout task with shortest timeout. There was a bug
8213 in task unregistration that caused problems. TODO has been
8214 updated to include that task system must be rewritten.
8216 * The client library will now resolve the client information when
8217 receiving JOIN notify from server for client that we know but
8218 have incomplete information.
8220 * Rewrote parts of silc_server_remove_from_channels and
8221 silc_server_remove_from_one_channel as they did not remove the
8222 channel in some circumstances even though they should've.
8224 * Encryption problem encountered in server:
8226 The LEAVE command used to send the Channel Key packet to the
8227 router immediately after generating it. However, the code
8228 had earlier sent Remove Channel user packet but not immediately,
8229 ie. it was put to queue. The order of packets in the router
8230 was that Channel Key packet was first and Remove Channel User
8231 packet was second, even though they were encrypted in the
8232 reverse order. For this reason, MAC check failed. Now, this
8233 is fixed by not sending the Channel Key packet immediately but
8234 putting it to queue. However, this is more fundamental problem:
8235 packets that are in queue should actually not be encrypted
8236 because packets that are sent immediately gets encrypted
8237 actually with wrong IV (and thus MAC check fails). So, packets
8238 that are in queue should be encrypted when they are sent to
8239 the wire and not when they put to the queue.
8241 However, the problem is that the current system has not been
8242 designed to work that way. Instead, the packet is encrypted
8243 as soon as possible and left to the queue. The queue is then
8244 just purged into wire. There won't be any fixes for this
8245 any time soon. So, the current semantic for packet sending
8248 o If you send packet to remote host and do not force the send
8249 (the packet will be in queue) then all subsequent packets to the
8250 same remote host must also be put to the queue. Only after the
8251 queue has been purged is it safe again to force the packet
8254 o If you send all packets immediately then it safe to send
8255 any of subsequent packets through the queue, however, after
8256 the first packet is put to queue then any subsequent packets
8257 must also be put to the queue.
8259 Follow these rules and everything works fine.
8261 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8263 * Added new function silc_server_remove_clients_by_server to
8264 remove all client entries from ID list when the server connection
8265 is lost. In this case it is also important to invalidate all
8266 client entires as they hold the invalid server entry. This
8267 fixes fatal bug when server has lost connection and will reconnect
8270 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8272 * Made some sanity checks to silc_server_daemonise like to check
8273 whether the requested user and group actually exists.
8275 * Added sanity check to SKE's silc_ske_responder_finish to check
8276 that the public and private key actually is valid.
8278 * Invalidate the client's nickname when receiving Replace ID
8279 packet and the Client ID is being replaced. This means that the
8280 server will query the nickname if someone needs it (client)
8283 * Sort the ID Cache in client library when the ID Cache data
8284 has changed (needs sorting).
8286 * Do not allow for SILC client to create several connections to
8287 several servers. The client does not support windows right now
8288 and generating multiple connections causes weird behaviour.
8290 Irssi-silc client does support windows and can handle several
8291 connections without problems, see: www.irssi.org and SILC plugin.
8293 * Fixed some places where client was added to the IDList. The
8294 rule of thumb is following (in order to get everything right):
8295 If the client is directly connected local client then the
8296 `connection' argument must be set and `router' argument must be
8297 NULL to silc_idlist_add_client function. If the client is not
8298 directly connected client then the `router' argument must
8299 bet set and the `connection' argument must be NULL to the
8300 silc_idlist_add_client function.
8302 * The funtion silc_server_packet_send_local_channel actually did
8303 not check whether the client was locally connected or not. It
8304 does that now. Fixed a bug related to LEAVE command.
8306 * Fixed Remove Channel User payload parsing bug in server's
8307 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
8309 * The server's silc_server_save_channel_key now checks also the
8310 global ID list for the channel as it might not be in the local
8311 list. Fixed a bug related to LEAVE command.
8313 * Is this the end of the [<unknown>] buglet that has been lurking
8314 around for a long time? A little for loop fix in server's
8315 silc_server_command_whois_parse that is used by both IDENTIFY
8316 and WHOIS command. At least, this was a clear bug and a cause
8317 of one type of [<unknown>] buglet.
8319 * WHOIS and IDENTIFY commands call the function
8320 silc_server_command_[whois/identify]_check function even if
8321 we are not router server.
8323 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8325 * Added --with-gmp configuration option. If set the GMP
8326 is always compiled in the SILC source tree. If not set then
8327 it is checked whether the system has the GMP3 installed. If
8328 it has then the GMP won't be compiled (the system's headers
8329 and library is used), if it doesn't have it then the GMP is
8330 compiled in the SILC source tree.
8332 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8334 * Changed RSA private exponent generation to what PKCS #1
8335 suggests. We try to find the smallest possible d by doing
8336 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
8337 not security fix but optimization.
8339 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8341 * Added new config entry [Identity] to fork the server and run
8342 it as specific user and group. A patch from Bostik.
8344 * Imported Dotconf configuration library into lib/dotconf.
8345 This will be used to create the SILC configuration files later.
8346 It will appear in the distsribution after this commit.
8348 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8350 * A big code auditing weekend happening. Auditing code for
8351 obvious mistakes, bugs and errors. Also, removing any code
8354 Removed files for being obsolete:
8356 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
8357 inline in the file lib/silcutil/silcbuffer.h)
8359 o lib/silcutil/silcbufutil.c (the header has inline versions)
8361 Changed code to fix possible error conditions:
8363 o The buffer formatting routines now check that the destination
8364 buffer really has enough space to add the data. This applies for
8365 both buffer formatting and unformatting
8366 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
8367 unformatting was changed to accomodate following rules:
8368 XXX_*STRING_ALLOC will allocate space for the data into the pointer
8369 sent to the function while XXX_*STRING will not allocate or copy
8370 the data into the buffer. Instead it sets the pointer from the
8371 buffer into the pointer sent as argument (XXX_*STRING used to
8372 require that the pointer must be allocated already). This change
8373 makes this whole thing a bit more consistent and more optimized
8374 (note that the data returned in the unformatting with XXX_*STRING
8375 must not be freed now). The routines return now -1 on error.
8377 o Tried to find all code that use buffer_format and buffer_unformat
8378 and added return value checking to prevent formatting and
8379 especially unformatting errors and possible subsequent fatal
8382 o Changed ske->x and ske->KEY to mallocated pointers in
8383 lib/silcske/silcske.h. Fixed possible data and memory leak.
8385 o Added return value checking to all *_parse* functions. Fixed
8386 many memory leaks as well.
8388 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
8389 so that buffer overflows would not happen. All code now also
8390 checks the return value as it can fail.
8392 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8394 * Added reconnection support to server if the normal server looses
8395 its connection to the router (for example if router is rebooted).
8396 The server performs normal reconnection strategy implemented
8397 to the server. Affected file silcd/server.c.
8399 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8401 * Added new packet type SILC_PACKET_SET_MODE that is used to
8402 distribute the information about changed modes (for clients,
8403 channels and clients channel modes) to all routers in the
8404 network. Updated the protocol specification accordingly.
8406 Added functions into silcd/packet_send.c and
8407 silcd/packet_receive.c: silc_server_send_set_mode,
8408 silc_server_set_mode.
8410 Added new files silcmode.[ch] into lib/silccore that implements
8411 the encoding and decoding of Set Mode Payload. Added new type
8412 SilcSetModePayload. Moved the definitions of different modes
8413 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
8415 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8417 * Oops, a little mistake in server's connection authentication
8418 protocol. The protocol is not ended with FAILURE but with
8419 SUCCESS if the authentication is Ok. :) Affected file is
8422 * Implemented NICK_CHANGE notify handling in server in the file
8423 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
8424 the local clients on the channel. After the changing nickname
8425 in router environment snhould work and the [<unknown>] nickname
8426 should appear no more.
8428 The silc_server_replace_id function that receives the Replace ID
8429 payload now sends the NICK_CHANGE notify type also in the file
8430 silcd/packet_receive.c
8432 * Changed WHOIS and IDENTIFY command to support the maximum amount
8433 of arguments defined in protocol specs (3328 arguments). This
8434 fixed a bug that caused problems when there were more than three
8437 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8439 * Added extra parameter, command identifier, to the
8440 silc_client_send_command so that explicit command identifier
8443 Changed that ID list routines uses specific command identifier
8444 when sending WHOIS/IDENTIFY requests to the server so that they
8445 can be identified when the reply comes back.
8447 Affected files lib/silcclient/command.[ch],
8448 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
8450 * Added `sender' argument to silc_server_packet_send_to_channel
8451 to indicaet the sender who originally sent the packet to us
8452 that we are now re-sending. Ignored if NULL. Affected file
8453 silcd/packet_send.[ch].
8455 * Added some server statistics support in silcd/server_internal.h
8456 SilcServerStatistics structure and around the server code. Also
8457 send some nice statistics information when client is connecting
8460 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8462 * Fixed channel ID decoding in server's JOIN command reply in
8463 silcd/command_reply.c
8465 * Fixed braodcasting of replace ID payload to not to send it if
8466 we are standalone server in silcd/packet_receive.c.
8468 * Fixed all channel message sending routines to not to send
8469 packets to clients that has router set, since they are routed
8470 separately in the same function earlier. Affects file
8471 silcd/packet_send.c and all channel packet sending functions.
8473 * In USERS reply, res_argv[i] are not allocated, the table
8474 is allocated. Thus changed that free the table, not its
8477 * In server's whois_check and identify_check if the client is
8478 locally connected do not send any WHOIS commands - they are not
8481 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8483 * Fixed some minor bugs in client when sending WHOIS command. The
8484 arguments was in wrong order.
8486 * Removed statis function add_to_channel from server in
8487 silcd/command.c that was previously used with the joining but
8490 * Tested USERS command in router environment successfully with two
8491 routers, two servers and two clients.
8493 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8495 * Reorganized the USERS command and command reply in client library
8496 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
8497 When the command is given by user we register a pending command
8498 callback that will reprocess the command after the reply has been
8499 received from the server. When reprocessing the packet we then
8500 display the information. Thus, the USERS information is displayed
8501 now in the command callback instead of in the command reply
8502 callback. The processing of the command is same as previously
8503 when server has sent the command reply in the JOINing process.
8505 * Added to USERS command in silcd/command_reply.c to join the client,
8506 we didn't use to know about, to the channel after we've created
8507 a client entry for it. Also, for clienet we did know already still
8508 check whether it is on the channel or not and add it if not.
8510 * Removed silc_server_command_join_notify as the function and its
8513 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8515 * Changed the client's pending command handling to the same as the
8516 server's pending command handling. It is also now possible to
8517 execute command reply functions from other command reply
8518 function as the function callbacks for commands and command
8519 replies are one and same. The pending commands are not static
8520 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8521 in client connection context. Thus, pending commands are server
8522 connection specific as it is convenient.
8524 Changed the function silc_client_command_pending and
8525 silc_client_command_pending_del and added new function
8526 silc_client_command_pending_check. Removed the
8527 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8530 * Added cmd_ident, current command identifier, to the client
8531 connection context in lib/silcclient/client.h to keep track on
8532 command identifiers used in command sending. Client's command reply
8533 function handling now supports the mandatory command identifiers.
8535 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8536 funtions in client to fully support pending command callbacks.
8538 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8539 as one of the arguments to the application in the command reply
8542 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8543 before first releasing SILC but came back. Now it is removed again
8544 and should come back nomore. The FORWARDED flag was used only
8545 by the JOINing procedure by forwarding the command packet to router.
8546 Now, the JOINing procedure has been changed to more generic (due
8547 to various router environment issues) and FORWARDED is not needed
8548 anymore for anything. The protocol specification is yet to be
8551 Now, removed silc_server_packet_forward from server and the flag
8552 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8554 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8556 * Renamed NAMES command to USERS command. The NAMES was named that
8557 due to historical reasons. Now it is renamed. Also, rewrote
8558 parts of the USERS command. The nickname list is not sent anymore
8559 by the server. Only Client ID and mode lists are sent in the USERS
8560 command. Changed this also to the protocol specification.
8562 The client now resolves the names and stuff after it receives
8563 the USERS list from the server when joining to the channel.
8565 * WHOIS and IDENTIFY commands has been changed to support multiple
8566 Client ID's per command. One can now search for multiple users
8567 in the network by sending only one WHOIS or IDENTIFY command.
8568 Changed the code and the protocol specifications.
8570 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8571 uses silc_server_command_whois_parse to parse the request. */
8573 * If normal server, do not parse the WHOIS and IDENTIFY requests
8574 before sending it to the router. Saves some time.
8576 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8578 * Fixed JOIN command on client library. Wrong number of arguments
8579 used to crash the client.
8581 * Added silc_server_channel_has_global function to check whether
8582 channel has global users or not.
8584 * Added silc_server_channel_has_local function to check whether channel
8585 has locally connected clients on the channel.
8587 * The silc_server_remove_from_one_channel now checks whether the
8588 channel has global users or not after given client was removed from
8589 the channel. It also checks whether the channel has local clients
8590 on the channel anymore. If it does not have then the channel entry
8591 is removed as it is not needed anymore.
8593 * The silc_server_notify now checks on JOIN notify whether the joining
8594 client is one of locally connected or global. If it is global then
8595 the channel has now global users on the channel and that is marked
8596 to the channel entry. Also, it now saves the global client to
8597 global list who is joining and JOINs it to the channel. This is
8598 for normal server, that is.
8600 Changed silc_server_send_notify_on_channel,
8601 silc_server_packet_relay_to_channel and
8602 silc_server_packet_send_to_channel check if we are normal server
8603 and client has router set (ie. global client) do not send the
8604 message to that client, as it is already routed to our router.
8606 * Implemented LEAVE notify type handling in silc_server_notify
8609 * Tested LEAVE command in router environment successfully. Tested
8610 with two routers, two servers and two clients.
8614 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8616 * Implemented SIGNOFF notify type handling in silc_server_notify
8619 * silc_server_remove_id now removes the client entry from all channels
8620 it has joined and thusly sends SIGNOFF notify type.
8622 * Rewrote the NAMES list generation in server by removing two excess
8623 loops. The lists are created now inside one loop.
8625 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8627 * silc_server_remove_channel_user checks now also global list
8628 for channel and client.
8630 * silc_server_new_channel_user checks now both local and global
8631 list for channel and client. Fixed a bug in client id decoding.
8632 Used to decode wrong buffer.
8634 * silc_server_channel_message checks now both local and global
8635 list for channel entry.
8637 * Tested channel joining (hence JOIN) in router environment
8638 successfully. Tested with two routers, two servers and two
8641 * Tested channel message sending in router environment successfully.
8643 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8645 * Added silc_server_save_channel_key into server.[ch] to save the
8646 received channel key in Channel Key payload processing. It is
8647 also used in JOIN command reply handling.
8649 Equivalent function silc_client_save_channel_key added into
8650 client.[ch] into client library.
8652 * Changed JOIN command reply to send information whether the channel
8653 was created or not (is existing already) and the channel key
8654 payload. Changed protocol specs accordingly.
8656 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8657 the request was sent by ID and not by nickname. Crashed on
8660 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8662 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8663 now correctly save the received data.
8665 * silc_server_free_sock_user_data now notifies routers in the
8666 network about entities leaving the network.
8668 At the same time implemented functions silc_server_remove_id
8669 and silc_server_send_remove_id to receive and send REMOVE_ID
8670 packets. The packet is used to notify routers in the network
8671 about leaving entities. The ID removed will become invalid in
8674 * Added function silc_idlist_del_server into server. Removes and
8675 free's server entry from ID list.
8677 * silc_server_private_message function now checks, if we are router,
8678 that the destination ID really is valid ID, naturally.
8680 * In router when NEW_ID packet is received (for new client) the
8681 hash of the Client ID is saved in the ID Cache but the
8682 client->nickname is set to NULL, instead of putting the hash
8685 IDENTIFY command now also checks that client->nickname must be
8686 valid. If it is not if will request the data from the server who
8687 owns the client. Added new function
8688 silc_server_command_identify_check.
8690 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8691 to set the command to already allocated Command Payload.
8693 * Tested private message sending in router environment with two
8694 routers, two servers and two clients. Fixed minor bugs and now
8697 * Fixed segfault from client's NAMES command. Used to crash if
8700 * Forwarded packets must not be routed even if it is not destined
8701 to the receiver. Changed server code comply with this.
8703 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8705 * Added `require_reverse_mapping' boolean value to ServerParams
8706 structure. If TRUE (not default) the server will require that
8707 the connecting host has fully qualified domain name.
8709 If the reverse mapping is not required and hostname could not be
8710 found the IP address is used as hostname.
8712 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8714 * Implemented version string checking to both client and server.
8715 The check is incomplete currently due to the abnormal version
8716 strings used in development version of SILC.
8718 * Changed all command functions in server to use the new
8721 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8723 * Changed char *data to unsigned char *data in ID Cache system to
8724 support binary data as ID Cache data. Changed code to support
8725 binary data in lib/silccore/idcache.c.
8727 * Renamed silc_server_packet_relay_command_reply to
8728 silc_server_command_reply as it is normal packet receiving
8729 function. Rewrote the function to accept command replys for
8730 servers and not only for clients.
8732 * Mark remote router always as registered server if we are connecting
8733 to it. Otherwise, commands sent by the router to us are ignored.
8735 * All ID List find routines now returns the ID Cache Entry pointer
8736 as well if requested.
8738 * WHOIS command works now in router environment, tested with two
8739 routers, two servers and two clients.
8741 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8742 in router environment (as it is almost equivalent to WHOIS) but
8743 hasn't been tested thoroughly. Added new functions:
8745 silc_server_command_identify_parse
8746 silc_server_command_identify_send_reply
8747 silc_server_command_identify_from_client
8748 silc_server_command_identify_from_server
8750 * Disabled route cache adding because adding two different ID's with
8751 same IP replaces the old cache entry thus giving wrong route.
8752 The entry->router->connection is always the fastest route anyway
8753 so route cache may not be needed. Of course, new routes maybe
8754 established after receiving the ID when the entry->router->connection
8755 might not be anymore the most optimal.
8757 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8759 * Add route cache for received ID for fast routing.
8761 * Added silc_server_packet_route to route received packet on router
8762 that is not destined to us.
8764 * Renamed silc_server_get_route to silc_server_route_get.
8766 * Added id_string and id_string_len fields into SilcServer to
8767 include encoded ServerID for fast comparing without excess
8768 encoding of the ID's.
8770 * Cleaned up WHOIS command on server side. Added following static
8773 silc_server_command_whois_parse
8774 silc_server_command_whois_check
8775 silc_server_command_whois_send_reply
8776 silc_server_command_whois_from_client
8777 silc_server_command_whois_from_server
8779 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8780 arguments in command replies. All command functions should be
8781 updated to use this macro.
8783 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8785 * Minor typo fixes on command reply handling on server.
8787 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8789 * Added silc_server_command_add_to_channel internal routine to add
8790 the client to the channel after router has created the channel and
8791 sent command reply to the server.
8793 * Added generic silc_server_send_command to send any command from
8796 * Use static buffer with ID rendering instead of duplicating data.
8798 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8800 * Fixed a channel user mode bug when joining to a channel server gave
8801 everybody channel founder rights, oops.
8803 * We mark ourselves as the router of the incoming server connection
8804 if we are router ourselves. This way we can check in some packet
8805 sending functions whether it is locally connected server. For
8806 incoming router connections we put NULL.
8808 * For router sending packets locally means now always sending the
8809 packet cell wide; to local clients and local servers. For normal
8810 server sending packet locally means sending it to only local
8813 * Fixed the JOIN command to really work in router environment. If the
8814 channel is created it is always created by the router. Router is
8815 also responsible of making the initial joining to the channel,
8816 sending JOIN notify to the sending server and distributing
8817 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8818 does not exist server doesn't do anything else but forward the
8819 command to the router which performs everything.
8821 * Added silc_server_send_channel_key function to send the Channel Key
8824 * Added silc_server_create_channel_key to create new channel key. The
8825 channel key is now re-generated everytime someone joins or leaves
8826 a channel, as protocol dictates. Note: channel->key_len is the
8829 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8831 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8832 packet_receive.[ch] to separate packet sending and receiving
8833 routines. The server.[ch] now includes everything else including
8834 actual packet processing (writing and reading data) and other
8837 Renamed silc_server_private_message_send_internal to
8838 silc_server_send_private_message. The routine is still though
8839 used only to relay private messages as server does not send
8840 private messages itself.
8842 Renamed silc_server_new_channel to silc_server_create_new_channel
8843 and added new function sicl_server_new_channel that handles the
8844 incoming New Channel packet. Added also new sending function
8845 silc_server_send_new_channel to send New Channel Payload.
8847 * Added new function silc_server_notify to process incoming notify
8848 packet to the server/router. Server may then relay the notify
8849 to clients if needed.
8851 * Added new function silc_server_new_channel_user to process incoming
8852 New Channel User packet. Router will redistribute the packet and
8853 send JOIN notify to its local clients and locally connected servers
8854 if needed. Normal server will send JOIN notify to its local client
8855 on same channel when received this packet. Added also corresponding
8856 sending function silc_server_send_new_channel_user to sent the
8859 * Added boolean route argument to send_notif_to_channel and
8860 packet_send_to_channel functions to attempt to route the packet
8861 if it is TRUE and send only locally if it is FALSE.
8863 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8865 * silc_server_replace_id now broadcasts the received replace ID
8866 packet if it is not broadcast packet already. The router must
8867 broadcast to inform other routers about changed ID.
8869 * Added backpointer to server's router into SilcServer context in
8870 silcd/server_internal.h.
8872 * Fixed silc_server_packet_broadcast to send correct broadcast
8875 * The channel key is now distributed to the local client as soon
8876 as it is received from the router (in router environment) so that
8877 no other packet may be sent for the channel until client has
8880 * silc_server_remove_channel_user now broadcasts the received
8881 Remove Channel User packet if it is not broadcast packet already.
8882 The router must broadcast to inform other routers about removed
8885 * Added users field into SilcPacketContext that is a reference count
8886 of the context. One can increase the reference count by calling
8887 silc_packet_context_dup which is now changed to just increase the
8888 reference count instead of duplicating the data. The reference
8889 count is decresed by calling silc_packet_context_free that will
8890 free the data after the reference count hits zero.
8892 For now on the packet context and everything allocated into it
8893 (including the raw packet from network) must be freed by calling
8894 the new silc_packet_context_free function. Added also new function
8895 silc_packet_context_alloc that must be used now to allocate the
8896 context. This also means that if a routine is asynchronous from
8897 silc_[client/server]_packet_parse_type the packet context must
8898 be duplicated by calling silc_packet_context_dup. Otherwise it
8899 gets free'd after silc_[client/server]_packet_parse_type returns.
8900 Also, one must remember that if packet is duplicated then its
8901 reference count must be decresed by calling the free function as
8902 many times as it was duplicated.
8904 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8905 from both client and server.
8907 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8909 * Made joining to a channel working in router environment.
8911 * Cleaned up JOIN command on server side and create function
8912 silc_server_command_join_channel internal routine to make the
8915 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8917 * Changed silc_command_pending list to SilcDList. Also, added
8918 `ident' field to SilcServerCommandPending structure to identify
8919 the reply and to call correct callback.
8921 Added silc_server_command_pending_check function to replace the
8922 corresnponding macro. The silc_command_pending list is not
8925 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8926 to set identifier to previously allocated Command Payload. It
8927 is used to set identifier for command when resending Command
8930 * Added silc_command_payload_encode_payload to encode Command
8931 Payload buffer from SilcCommandPayload structure.
8933 * Added silc_argument_payload_encode_payload to encode Argument
8934 payload buffer from SilcArgumentPayload structure.
8936 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8938 * Changed WHOIS command to support router connection on server side.
8939 The whois request is always sent to router unless the server is
8940 standalone server. After server has received the reply from the
8941 router will it send the reply to the client.
8943 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8944 broadcast received broadcast packet. The function is used only
8945 by router. The broadcast packet is always sent to the router's
8948 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8949 render given ID to printable string, for log files for example.
8951 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8953 * Made basic router to router connections working. At least they
8954 can now connect to each other but nothing really works the way
8955 they are supposed - yet.
8957 * Added new initiator token to RouterConnection configuration
8958 file in silcd/serverconfig.[ch]. It is used to tell whether we
8959 are the initiator to the remote router or whether we'll expect
8960 the other end to connect.
8962 * Moved registering of listener task to silc_server_init, hence
8963 the server starts listenning as soon as it is run, even if it
8964 does not have connections to other routers. Let's see how well
8967 * Changed default connection retry timeouts for more suitable in
8970 * Removed cipher and such arguments from silc_idlist_add_client
8971 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8972 Added new function silc_idlist_add_data to add the keys and stuff
8975 * Added SilcIDListData structure and added it to SilcClientEntry
8976 and SilcServerEntry as their first field in the structure. This
8977 way we can explicitly cast the ID entries to the SilcIDListData
8978 structure and get common data for the entries. In past, we had
8979 to first check what type of connection it is and then cast it to
8980 correct ID entry type. Now, we can directly cast the opaque
8981 pointer to the SilcIDListData (no matter what ID entry it actually
8982 is) and get the data needed.
8984 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8986 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8987 in some circumstances even if threre were timeout tasks, though not
8988 IO tasks, but tasks anyway. Now fixed.
8990 * Defined SilcServerConnection structure to hold connection specific
8991 stuff about directly connected servers and routers. The definition
8992 is currently in silcd/server_internal.h. I thought about having
8993 a bit more important role fro this struct but for now it is used
8994 only when connecting to other server (or router actually).
8996 * Added connecting retry support in server when connecting to
8997 router(s). The retry feature implement exponential backoff
8998 algorithm. Also, added SilcServerParams structure to hold default
8999 parameters for server. For now, it include these retry settings
9000 and are hard coded. After server is moded to be as Silc Server
9001 Library this structure will be more important.
9003 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9005 * Changed client librarys channel->clients table to SilcList and
9006 changed code accordingly.
9008 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9010 * Changed client's channel table to SilcList and changed code
9011 accordingly. Also changed SilcChannelClientEntry to include back-
9012 pointer to the channel so that client entry can use that structure
9013 as list as well and we have fast cross-reference to the channel.
9014 This change dramatically decreased the complexity of channel
9015 handling with client entry and vice versa (removed one extra
9016 loop when searching for channel entry from many functions).
9018 * Changed server->sim from table to SilcDList and changed code
9021 * NAMES command can now be used from user interface. It will show
9022 the user list on the channel, neatly.
9024 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
9025 Code now saves realname of the user if it becomes available.
9027 * Renamed configure.in to configure.in.pre and made ./prepare
9028 script to automatically add correct version string to
9029 configure.in which it creates from configure.in.pre.
9031 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9033 * NAMES command reply now shows users mode with the nickname when
9036 * Moved silc_client_ch[u]mode[_char] functions from
9037 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
9038 place sucks, they are utility functions and should be in some
9041 * Fixed some unsigned int's to unsigned short's. Patch by cras.
9043 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
9046 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9050 * Added TRQ (efficient deque and list library) into lib/trq. This is
9051 a very good list library that is currently used in the SILC. Defined
9052 SilcList API over the library because I didn't like the API very
9053 much. See lib/trq/silclist.h for the API and examples of how to
9054 use the API. Fixed various places in the code to use the new
9055 SilcList API. The SilcList is meant for lists that has a structure
9056 already defined as a list. It is not suitable to add just some
9057 context to the list (in TRQ, the context is the list actually).
9059 So, I defined SilcDList that can be used for the purpose where
9060 predefined list structure does not exit. This can be used as
9061 such list. Now some context just can be added to the SilcDList.
9062 Currently this list is not used in the SILC just yet, though there
9063 are a lot places where this can replace dynamically allocated
9064 tables and I will fix these places, later, to use SilcDList.
9065 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
9066 and use TRQ internally).
9068 Also fixed some annoying warning messages that the original TRQ
9069 code generated. Also minor changes to TRQ's Makefile.in.
9071 * Added support for querying by Client ID to both WHOIS and
9072 IDENTIFY commands into server, as required by the protocol.
9074 * Removed method function pointers from SilcBuffer structure. They
9075 weren't used to anything and just increased the context size for
9076 no good reason. This change also made silc_buffer_alloc and
9077 silc_buffer_free functions inline functions.
9079 * Disabled command flooding detection support until it's fixed so
9080 that it accepts commands in but does not execute them more than once
9083 * Added silc_net_localhost(), to return local hostname, into
9084 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
9085 that must be initialized before calling silc_client_init.
9087 * Added new function: silc_server_send_notify_on_channels to send
9088 notify messages to all channels client has joined. It is assured
9089 that the message is sent only once per client.
9091 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
9092 lib/silcutil/silcutil.[ch] as silc_format function. The new
9093 function is generic and is used by server as well, not only by
9094 the logging routines.
9096 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
9097 the provided version string was not acceptable. Added new function:
9098 silc_ske_check_version into lib/silcske/silcske.h. The function
9099 must be implemented by the application (client or server) and it
9100 does not reside in the SKE library. The function checks the version
9101 string remote end sent.
9103 * Added back pointers (to opaque context and to SilcSocketConnection)
9104 into SilcPacketContext structure into lib/silccore/silcpacket.h.
9106 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
9107 duplicate packet context structure.
9109 * Changed `notify' client operation to send same arguments as client
9110 receives from server except for ID's. ID's are mapped to correct
9111 ID entry and that is returned. Also, if channel entry is not sent
9112 by server but the notify is for channel the channel entry is sent
9113 to application (otherwise application doesn't know that it is for
9114 channel (library gets it from packet's Destination ID)).
9116 * Added silc_client_remove_from_channels into client library to
9117 remove a client from all channels it has joined to. Used when
9118 received SIGNOFF notify from server. Added also new function
9119 silc_client_replace_from_channels to replace old ID entry with
9120 new ID entry on all channels. Used when received NICK_CHANGE
9123 * Fixed ID Cache list handling in silc_idlist_get_client in
9124 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
9125 to get (or query) client by ID.
9127 * Updated TODO list.
9129 * Added connection authentication status message defined by the
9130 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
9131 support for these into the code in client and server side.
9133 * Added generic function silc_client_send_command to send any command
9134 with variable argument list. Application should use this function
9135 to send commands if the command functions provided by the library
9136 does not suite for the application's user interface needs.
9138 * Added new `failure' client operation. Application is notified about
9139 received failure packet if client is executing a protocol. In this
9140 case the protocol's execution has failed.
9142 * Added SKE's end notify to send the SKE_SUCCESS notify message that
9143 is required by the protocol.
9145 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
9146 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
9149 * Added status flag to SilcSKE object to indicate realtime status
9150 of the SKE protocol.
9152 * Application receives now exactly same command reply arguments as
9153 the library receives from server. However, if ID is received the
9154 corresponding ID entry is returned to the application (eg. Client
9155 ID is mapped to correct SilcClientEntry entry and that is returned).
9156 Changed command_reply client operation due to this change.
9158 * Changed all ID's in commands and in command replys as ID Payloads.
9159 Change affected both client and server side codes.
9161 All ID's sent in SILC network (with execption of ID's in SILC
9162 Packet header) are sent in ID Payload to support variable length
9165 * Server now notifies nick changes and notifies all clients on
9166 the channels about the new nickname (about the new Client ID,
9169 * Implemented CMODE command to change channel modes. Supports all
9170 channel modes defined by the protocol specs except ban and invite
9171 lists. (Also, private channel key mode is supported but support for
9172 setting private channel key in client is missing, thus, this mode
9173 has no effect on client side (except that server requires that the
9174 client uses private channel key and normal channel traffic does not
9177 Also, invite mode works per se, but INVITE command does not work
9178 yet correctly, so you can set channel as invite only channel but
9179 inviting clients to the channel does not work (it is yet to be
9180 thought what's the best way to do it).
9182 * Added new command SILC_COMMAND_CUMODE to change user mode on the
9183 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
9184 Implemented CUMODE command to change user's mode on the channel.
9185 Supports all modes defined by the protocol specs.
9187 * Added NAMES command reply to return users modes on the channel.
9189 * Removed unnecessary and slow ciphers from lib/silccrypt.
9191 * Set SO_KEEPALIVE option to connection sockets by default.
9193 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
9195 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
9196 redefined the Notify Payload into protocol specs.
9198 * Added silc_id_payload_parse_id to get ID directly from raw
9201 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9203 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
9204 accept searching by Client ID as well.
9206 * Added support for LEAVE and SIGNOFF notify types in client library.
9208 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
9209 to parse ID Payload from raw data.
9211 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9213 * Added flags parameter into silc_ske_assemble_security_properties
9214 function in lib/silcske/silcske.[ch].
9216 * Changed notify client operation to fit better for notify messages
9217 sent by server. The notify payload received from server is now
9218 passed to the application (after parsing it to SilcNotifyPayload).
9219 It is application's responsibility to retrieve the arguments
9220 from the payload and show the message the way it wants. The message
9221 sent by server is implementation specific.
9223 * Changed public keys to comply with the protocol specification.
9224 Old public keys are not supported anymore and are not compatible.
9226 * Removed nickname from Channel Payload as the latest draft removed
9227 it. The client must resolve the nickname from the NAMES command
9228 reply received when it joined the channel.
9230 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
9232 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9234 * Fixed some errors in protocol specification drafts.
9236 * Created lib/silccore/silcnotify.c to implement Notify Payload
9237 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
9238 generic payloads described by protocol specifications. The file
9239 includes implementations for ID Payload and Argument Payload.
9241 * Changed Command Payload implementation to use the new Argument
9242 Payload. Changed command_xxxx_payload to command_payload_xxxx
9243 to comply with SILC coding conventions.
9245 * Added suppport for Argument Payload handling in Notify Payload
9246 implementation as protocol requires it. Added the new support
9247 into server and client lib as well.
9249 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9251 * Added support for multiple nicknames on same channel. [n] is
9252 added locally to the nickname if there are more than one same
9253 nicknames on the channel.
9255 * Server now sends all nicknames that matched WHOIS request.
9256 Client also shows the list received from server.
9258 * Added TOPIC command to client side. User can now set and show
9259 current topic on channel.
9261 * Added MOTD command to client and server. Also, server sends the
9262 motd when client connects to the server.
9264 * Changed version strings to comply ISO 8601.
9266 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9268 * Fixed protocol error handling in client library. It should now
9269 cope even if the SKE fails for some reason.
9271 * Made new protocol specification drafts for submitting to IETF.
9273 * Implemented TOPIC command to server in silcd/command.c.
9275 * Added two new notify types into lib/silccore/silcnotify.h:
9276 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
9277 notify nickname change and topic setting/change on a channel.
9279 * API change of command_reply operation in client library. The
9280 application gets now the status type received from server as well.
9282 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9284 * Removed the function just added to lib/silcutil/silcschedule.[ch].
9286 * Cras fixed and optimized the packet handling even further and
9287 it should work now. Minor change to the prototype of function
9288 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
9290 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9292 * Added new function into lib/silcutil/silcschedule.[ch]:
9293 silc_schedule_with_fd to select() a specified fd. The function
9294 returns after timeout expires or data arrives or goes. The
9295 function is used by packet routines to wait that all data is
9296 received from network.
9298 * Fixed data reading from network in lib/silccore/silcpacket.c.
9299 The code now assures that all data is read from the fd and then
9300 continues packet processing. This was a bug fix since the code
9301 used to drop some data in some circumstances.
9303 * Added new function into lib/silcclient/client.[ch]:
9304 silc_client_start_key_exchange to start key exchange after
9305 connection has been established to server. The code internally
9306 now uses this funtion but its main purpose was to provide it
9307 for applications that perform their own connecting. After
9308 application has created a connection it merely calls this
9309 function to start the key exchange between client and server.
9310 The library takes care of everything else after that.
9312 Updated also lib/silcclient/README to explain the usage of
9315 * Do not send to application information that connection has
9316 been established. Application gets notified it by connect
9319 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9321 * Applied cras's patch to add silc_schedule_one function. The
9322 function runs scheduler once and returns.
9324 * Fixed the scheduler after cras messed it up. The timeout
9325 handling works now as it's supposed to work.
9327 * Added into lib/silccore/ silcnotify.h to include notify
9328 message types support. Changed silc_server_send_notify*
9329 functions, in server.[ch], to support those new notify types.
9330 Added the support for the notify types into client library,
9331 as well. Added new notify client operation into ops.h in
9334 * Changed silc_server_packet_send_to_channel to send normal
9335 packets instead of just channel message packets. The function
9336 is now used to send the notify packets to channels. It is not
9337 used to send channel message packets anymore, as server never
9340 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
9341 va_arg()s as it seems to require it nowadays. I guess, if SILC
9342 is compiled with older va_arg() the new code should work anyway.
9344 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9346 * Splitted core library. Core library (lib/silccore) includes
9347 now only SILC protocol specific core (and common) components.
9348 Created new utility library (lib/silcutil) that includes more
9349 generic purpose stuff. The stuff for util library was taken
9350 from the old core library. This was minor and easy split.
9352 * Created SILC Client Library (lib/silcclient) that includes
9353 implementation of the SILC client without user interface. This
9354 was major move from silc/ directory. The code has been changed
9355 so that it is transparent towards the user interface. The
9356 silc/ directory includes now the same user interface as before
9357 and it uses the new client library. Read lib/silcclient/README.
9358 Basicly, the client library performs everything else related
9359 to SILC except user interface handling. Also, configuration
9360 files are considered to be part of user interface and library
9361 does not handle them.
9363 This change also changed a lot of structures, function naming etc.
9364 Most important change was that SilcClientWindow object was
9365 renamed to SilcClientConnection in the client library. Created
9366 also new file lib/silcclient/ops.h. Also added new files
9367 silc/local_command.[ch] and silc/client_ops.[ch].
9369 All these changes were made to make it easier for user interface
9370 designers to create what ever user interface for the SILC client
9373 It is also expected that the server will be moved to lib
9374 directory as well and SILC Server Library will be created;
9375 sometimes in the future.
9377 * Removed Local commands from lib/silccore/silccommand.h as
9378 they are application specific and new client library does not
9379 handle any of those anymore.
9381 * Several functions moved to lib/silcutil/silcutilc.[ch] from
9382 old client implementation in silc/.
9384 * Added support for callback functions in SILC_LOG_* macros.
9385 Application can now set its own callbacks that will be called
9386 instead of using the default functions that will always print
9387 the debug messages to stderr (or stdout). Also, debugging can
9388 now be disabled by setting silc_debug to FALSE and re-enabled by
9389 setting it to TRUE. Note, that logging will still work even
9390 if debugging is disabled.
9392 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
9393 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
9394 silc_log_reset_debug_callbacks.
9396 * To enable debugging in silc client one must give now -d
9397 option on command line.
9399 * Changed silc_schedule_init to automatically allocate task queues
9400 if they are not allocated before calling it.
9402 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9404 * Added GMP 3.1 into math library.
9406 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9408 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
9409 a channel in SILC network. The packet is used by servers and
9410 routers to notify other routers that user has left a channel.
9411 This little feature was missing until now. Added the feature
9412 to protocol specification as well.
9414 Added functions: silc_server_send_remove_channel_user and
9415 silc_server_remove_channel_user into server.[ch].
9417 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
9418 lib/silccore/silcpacket.h. However, they are not implemented
9421 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9423 * Fixed joining to a channel and sending channel messages
9424 between server and router. The channel message sending should
9425 now work inside a cell.
9427 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9429 * Fixed the private message sending between server and router.
9430 The private message sending should now work inside a cell.
9432 * Added silc_server_replace_id into server.[ch] to replace
9433 existing ID in the SILC network.
9435 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
9436 and silc_idlist_replace_server_id into idlist.[ch] in server.
9438 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9440 * Fixed the server to server connections. Server can again now
9441 connect to router. Router to router connections probably does
9444 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9446 * Added dynamic protocol registering support. Now protocols can
9447 registered and unregistered on the fly. Patch by cras.
9449 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9451 * Added lib/contrib directory to hold routines that some platforms
9452 don't have but are needed by SILC.
9454 * Added getopt.c, getopt1.c and getopt.h from GNU C library
9455 into lin/contrib to provide getopt() and getopt_long() for
9456 those who don't have it.
9458 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9460 * Added AWAY command to client. When away message is set and
9461 client receives a private message packet the client automatically
9462 replies to the sender with the away message.
9464 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
9465 bug seemed to be the cause of recent problems when compiling
9468 * Added version detection support to SKE protocol specification
9469 and added the new changes to the SKE implementation as well.
9470 There were other minor changes in the SKE protocol as well.
9472 Many changes in lib/silcske/silcske.[ch] and in
9473 lib/silcske/payload.[ch].
9475 * Added ^U functionality, clear input line. Patch from cras.
9477 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9479 * Mainly small bugfixes on core library. Fixed some debugging
9480 logging and buffer overflow in silclog.c.
9482 * Updated config.sub and config.guess on the distribution tree.
9484 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9486 * Added command lagging support in server. Client may execute
9487 commands now only once in two seconds.
9489 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9491 * Optimized packet reception. MAC computation and checking is now
9492 also more optimized. A lot previously duplicated code is now
9493 used as generic by both client and server.
9495 * Fixed key pair generation in clientutil.c
9497 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9499 * Added into lib/silccore/silcbufutil.[ch] new function;
9500 silc_buffer_realloc.
9502 * Moved generic packet sending/encryption functions to
9503 lib/silccore/silcpacket.[ch] from client and server. Some
9504 rewriting of the functions.
9506 * Moved all generic packet reception/decryption functions to
9507 lib/silccore/silcpacket.[ch] from client and server. The
9508 packet processing is now much cleaner in both client and server.
9509 These were major changes in both client and server.
9511 * Created many common functions in server to do packet sending.
9512 Previously code were duplicated a lot, this has been removed
9515 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9517 * Rewrote major parts of the ID cache system. Don't know
9518 whether it is better now or not but at least the API is more
9521 * Major rewrite on ID cache stuff on client because of the ID
9522 cache API changes. Added idlist.c to client.
9524 * Also major rewrite on ID cache stuff on server as well.
9525 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9526 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9527 in hand, instead they are all put into the ID cache system now.
9528 All server_idlist_* routines uses ID cache now instead of
9529 traversing its own lists (those lists does not exist anymore).
9530 SilcIDList though still exists. Also, SilcXXXEntry's are
9533 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9535 * Finally made the SKE implementation compliant to the protocol
9536 specification. All mp integers are now binary encoded as
9537 opposed being HEX encoded.
9539 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9542 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9543 functions: silc_[encode/decode]_pem. Also added function
9544 silc_encode_pem_file to PEM encode with newlines ('\n') for
9547 * SILC public keys are now encoded either PEM or binary. Same
9548 option is for private keys as well. By default private keys
9549 are binary encoded and public keys PEM encoded. Silly HEX
9550 encoding were removed.
9552 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9553 function to create fingerprints.
9555 * Fixed a bug in SHA1; does not change the original data anymore.
9557 * Partly implemented INFO command on client and server side.
9558 Fixed CLEAR command. Changes to SERVER command; show current
9559 server(s) when giving command without arguments. Added
9560 VERSION command to client.
9562 * Added check to server that unregistered connections cannot
9563 execute commands (unless it is specificly allowed).
9565 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9567 * Fixed screen refresh.
9569 * Fixed channel joining bug from client. On some circumstances
9570 client tried to join to a channel it had already joined.
9572 * Added public key verification process into client's protocol.c.
9573 The client now verifies the public key from user and saves
9574 it into ~./silc/serverkeys/ directory.
9576 Added into: clientutil.[ch]: silc_client_verify_server_key.
9578 * Changed SKE protocol's silc_ske_initiator_finish function
9579 to accept callback function that verifies the received public
9580 key. Removed old silc_ske_verify_public_key function.
9582 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9584 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9585 silc_pkcs_private_key[_data]_set.
9587 * Made the password and public authentication more cleaner in
9588 server's protocol.c.
9590 * Removed historic and obsolete protocol `channel_auth' from
9591 both client and server.
9593 * Removed wrong way of sending command status messages from
9594 server to client in server's command.c. The old way violated
9595 protocol specification.
9597 Changes to silccore/silccommand.[ch]: removed
9598 silc_command_encode_status_payload -> not needed anymore,
9599 changed silc_command_encode_payload_va to accept extra
9600 argument on variable argument list. The argument type must
9601 now be provided to the function. Also, added new function:
9602 silc_command_encode_reply_payload_va which is same as
9603 normal command_encode_payload_va except command status type
9604 is provided as extra argument.
9606 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9608 * Added ~./silc directory handling. The directory includes the
9609 public and private keys for the client.
9611 Added silc_client_check_silc_dir, silc_client_create_identifier
9612 and silc_client_load_keys.
9614 * Implemented SILC protocol compliant public key. Added public
9615 and private key saving to and loading from files.
9617 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9618 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9619 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9620 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9621 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9623 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9624 silc_pkcs_load_[public/private]_key.
9626 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9628 * Added silc_server_get_route (route.[ch]) to get connection
9629 data for the fastest route for given ID.
9631 * Implemented INVITE command on client and server. The command
9632 were re-defined in the SILC Protocol Specification and the
9633 implementation now complies with the specification.
9635 * Implemented PING command on client and server.
9637 * Implemented NAMES command on client and server. The server side
9638 supports currently only normal server not router server yet.
9639 Some changes to NAMES definition in SILC protocol specification.
9641 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9643 * Implemented LEAVE command on client and server.
9645 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9646 again. This change was made to the protocol as well. Server
9647 should not violate the protocol specification anymore.
9649 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9651 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9652 was tested. SOCKS4 was not but should work anyway.
