134 SilcPKCS. Affected file lib/silccrypt/silcpkcs.[ch] and rsa.c.
136 * Fixed the usage of silc_pkcs_get_key_len since it returns the
137 length in bits not in bytes. Affected files are
138 lib/silcske/silcske.c, lib/silccore/silcauth.c and
139 silcd/server_query.c.

158 It is not able to send requested attributes in WHOIS command,
159 and also receive and process requested attributes. Added
160 silc_client_attribute_[add|del] and silc_client_attributes_get
161 functions. Added also `ignore_requested_attributes' to the
162 SilcClientParams to not use attributes in client. Affected
163 files are lib/silcclient/command.c, client_attrs.[ch],
164 silcclient.h, client_internal and client.[ch].

184 * Changed the silc_attribute_payload_encode to support list
185 of attributes (function may be called several times to add
186 a new attribute). Removed the silc_attribute_payload_encode_list
187 function. The encoding function now also automatically encodes
188 the data, so the caller does not need to do that. Affected
189 files lib/silccore/silcattrs.[ch].
191 * Added support for replying on behalf of the user to the
192 Requested Attributes in WHOIS command in the server. Affected
193 file silcd/server_query.c.

242 * Resumed client packet handling from server put the resumed
243 client on wrong list on router and caused the client not
244 be present on the network anymore. Now fixed to put the
245 client to correct list. Affected file silcd/packet_receive.c.
247 Wed Sep 18 15:13:48 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
249 * Various cleanup in error message output in config parsing code
250 and in server init code. Fixed error log files containing

260 Mon Sep 16 12:02:54 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
262 * Added 'app_context' to silc_schedule_init. It is an
263 application specific context that is delivered to application
264 in task callback functions. Affected files are
265 lib/silcutil/silcutil.[ch].
267 * The hb_context in SilcSocketConnection is not freed
268 automatically anymore (application must free it). Freeing
269 it automatic is inconsistent. Affected files are
270 lib/silcutil/silcsockconn.[ch].
272 Sun Sep 15 22:16:19 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

308 Mon Sep 9 12:18:18 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
310 * Incoming file transfer request cannot use same session as
311 the sending session. This can happen when sending file to
312 yourself. Crashed the client on quit. Affected file
313 lib/silcclient/client_ftp.c. Bug #24.
315 Sun Sep 8 18:39:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
317 * Implemented the draft-riikonen-precense-attrs draft and
318 the Attribute Payload into the lib/silccore/silcattrs.[ch].
320 Sun Sep 8 13:13:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
322 * Distribute the SERVER_SIGNOFF notify also to local backup
323 routers from the primary router. The backup router may not
324 have the signing of local server directly connected and need
325 to know about the signoff. Affected file silcd/server_util.c.
327 * Use the primary router as the origin of the locally connected
328 server when it is disconnecting from the backup router since
329 that's where it really is coming from. Now the clients from
330 the disconnecting server are removed correctly and "shadow"
331 clients are not left to the backup router. Affected file
334 Sat Sep 7 22:26:50 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
336 * If normal server is standalone and found existing but disabled
337 channel, do not re-create the channel since it creates
338 duplicate same channels. Affected file silcd/server.c.
340 * Added anonymous client connections support to server. New
341 "anonymous" configuration option to ConnectionParams section
342 added. If set to true, the username and hostname information
343 of the client will be scrambled and anonymous user mode is
344 set automatically to the user. Affected files are
345 silcd/serverconfig.[ch], silcd/packet_receive.c and server.c.
347 Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
349 * In JOIN notify handling, mark that the cache entry of the
350 client cannot be expired. Can cause crashes on normal
351 server (asserts client->channels). Affected file is
352 silcd/packet_receive.c.
354 * From now on distribution versions are used as protocol versions
355 instead of by default using the Toolkit base version as protocol
356 version. Affected file prepare.
358 * Do not set the locally resolved hostname for local client
359 entry but take what server sends. This way the real hostname
360 is showed in WHOIS for yourself. Affected file is
361 lib/silcclient/idlist.c and lib/silcclient/client.c.
363 * Resolve local info with IDENTIFY when connecting to server.y
365 Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
367 * Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
368 for implied search (not needed on platforms which has native
369 pthreads library). Use --without-pthreads to disable threads.
370 Affected file is configure.in.pre
372 * Fixed --with-iconv on platforms which need to bypass (broken)
373 native iconv(). Affected file is configure.in.pre
375 Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
377 * Moved -C option parsing in Irssi SILC client at same time
378 as other options. The UI was initialized earlier and caused
379 problems on command line. Bug #16. Affected file is
380 irssi/src/silc/core/silc-core.c.
382 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
384 * Added global variable silc_log_timestamp that tells silclog
385 wether to print or not the timestamp in the logging files.
386 Affected file lib/silcutil/silclog.[ch].
388 * Added silcd configuration option Timestamp in the Logging
389 section. Affected file silcd/serverconfig.[ch],
390 doc/example_silcd.conf.in.
392 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
394 * Fixed fingerprint checking to check for entirely empty
395 fingerprint instead of two first bytes when determining
396 if it is set. Bug #18. Affected file silcd/command.c.
398 * Fixed duplicate PKCS name registering to not allow it.
399 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
401 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>

410 didn't generate any output. Affected file
411 lib/silccrypt/silcrng.c
413 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
415 * Rewrote iconv checking, introduce --with-iconv for systems
416 which rely on libiconv. Check if iconv() provided by libc
417 is good enough, otherwise demand libiconv. Affected file
420 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
422 * Search for ldopen() also in libc. This enables SIM support
423 on *BSD systems. Based on patch from Alex Zepeda. Affected
424 file configure.in.pre
426 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>

452 Affected file silcd/command.c.
454 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
456 * Fixed buffer overflow and security problems (loosing bits
457 in CFB encryption) in SILC RNG. Problems reported by
458 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
460 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
462 * Added yet more checks that client is not expired on global
463 list if it is on channels. Affected file is
464 silcd/command_reply.c.
466 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
468 * Merged c0ffee's MIME signal patch which adds support for
469 sending also MIME messages in Irssi SILC Client, and handling
470 received MIME messages in a signal (and perhaps doing something
471 to non-textual MIME messages).
473 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
475 * Fixed pending command deletion in server and client library
476 to check the whole list instead of breaking after first found.
477 The affected files are silcd/command.[ch] and

480 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
482 * Return NO_SUCH_CHANNEL error in USERS for channel that is
483 secret or private, otherwise it's possible to find out
484 whether a secret channel exists or not. Affected file
487 * If CMODE change fails during the mode setting, assure that
488 the old mode mask is set for the channel back. Affected
489 file silcd/command.c.
491 * Fixed passphrase saving on +a channel on normal server
492 after successful JOIN command. Affected file silcd/command.c.
494 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
496 * Remove server/router operator privileges in DETACH command,
497 since it's possible to resume to server where these
498 privileges would not be allowed for the client. Affected
499 file silcd/command.c.
501 * Do not set to wait for backup in rehash of the server.
502 Affected file silcd/server.c.
504 * Do not check listener sockets when counting how many
505 socket connections we have. Affected file is
508 * Do not announce disconnected clients that are remaining
509 in history (for WHOWAS). This is because SIGNOFF notify
510 for these has been sent earlier already. Affected file
513 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
515 * Buffer overflow with CUMODE command's mode->mode character
516 conversion. Reported by Ville Räsänen. Affected file
517 lib/silcutil/silcutil.c.
519 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
521 * Allow heartbeat packets to go disabled connections anyway.
522 Affected files silcd/server.c and silcd/packet_send.c.
524 * Do not broadcast New Channel packets with List flag set
525 in the packet to backup routers. The router must check
526 for the correctness of the packets before sending them.
527 It is possible that router will have enforce Channel ID
528 change and this would cause desync in the backup router.
529 Affected file silcd/packet_receive.c.
531 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
532 are handled in list parsing. They are not list packets
533 anymore. Affected file silcd/packet_receive.c.
535 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
537 * Stop waiting for backup router through the timeout, not
538 directly after backup router has arrived. Affected file
541 * Do not re-create channel keys and send them when removing

545 * Notify distribution to backup routers was missing from
546 the silc_server_send_notify_dest function which caused
547 desyncing problems with backup router. Affected file is
550 * The client's channel removing was working wrong on
551 backup router. It assumed that it doesn't know global
552 information but backup router does know. For this reason
553 it could remove channel when it wasn't supposed to do that.
554 Affected file silcd/server.c and silcd/server_util.c.
556 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
558 * Stop for a couple seconds after badkup router has become
559 primary router. Affected file silcd/server.c.
561 * Added silc_server_remove_servers_by_server, which is used
562 to remove servers originated from some other server. Also
563 clients of those servers can be removed too. Affected file
564 silcd/server_util.[ch].
566 * When removing clients after a server has signed of remove
567 also all servers behind that server (unless they are known
568 to be available locally), and send SERVER_SIGNOFF for each
569 of the server separately. Also the signed off clients are
570 sent now separately per signed off server. The affected files
571 are silcd/server.c and silcd/server_util.[ch].
573 * All servers added with silc_idlist_add_server must always
574 have both "router" and "connection" pointers set. Otherwise,
575 bad server entries may be left around in the cache.
576 Affected file silcd/command_reply.c.
578 * Do not create the channel key in NEW_CHANNEL packet
579 processing if the channel is empty. Affected file
580 silcd/packet_receive.c.
582 * Completed backup router support for standalone routers.
583 Supports also servers in the cell that do not use the backup
586 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
588 * Fixed a bug in silc_string_regexify which did not add '^'
589 at the start of each string, and thus the matching was
590 not explicit. For example ban list iikone@*!*@* would
591 match also "priikone", which is wrong, it would have to be
592 *iikone@*!*@* to match also "priikone". Affected
593 file lib/silcutil/unix/silcunixutil.c.
595 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
597 * Enable all local server connections before updating client
598 caches when we've become backup router. Otherwise, signoff
599 packets may not reach the clients. Affected files are
600 silcd/server.c and silcd/server_util.[ch].
602 * Fixed a bug in version string parsing which could crash
603 the program with specially formatted version string.
604 Bug reported and patch provided by Ville Räsänen. Affected
605 file lib/silcutil/silcutil.c.
607 * Handle the disconnection immediately when DISCONNECT
608 packet is received in server. Affected file silcd/server.c.
610 * Primary router now waits a short time (10 seconds) for
611 backup router connection before accepting any other
612 connection (except local). Affected file silcd/server.c,
615 * Fixed a crash in client libary in NICK_CHANGE notify when
616 NICK_CHANGE arrived for client entry we are resolving
617 currently. Affected file lib/silcclient/client_notify.c.
619 * Call the sconn->callback completion even if error had
620 occurred. Start reconnecting always if connection to
621 primary router fails during backup router protocol.
622 Affected files silcd/server.c and server_backup.c.
624 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
626 * Added functions silc_server_send_opers and
627 silc_server_send_opers_notify to send packets stricly
628 to operators. Added macro SILC_SERVER_SEND_OPERS macro
629 to send variable argument notify to operators.
630 Affected files silcd/packet_send.[ch] and silcd/server.h.
632 * Removed UMODE rights checking with UMODE_CHANGE notify.
633 Affected file silcd/packet_receive.c.
635 * Server/router operator now receives notify when network
636 switches to backup router and when it resumes the use of
637 primary router. Affected file silcd/server.c and
638 silcd/server_backup.c.
640 * Fixed the updating of client information after backup
641 resuming protocol is over; update all except local clients
642 to the new primary router. The affected file is
645 * Added support for closing active connections in rehash
646 that were unconfigured by the user. Supports currently
647 closing server and router connections. Affected file
650 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
652 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
654 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
655 is NULL since seems that on some platforms NULL is allowed
656 and on some it's not. Fallback encoding is used instead.
657 Affected file lib/silcutil/silcstrutil.c.
659 * Fixed statistics updating for incoming server connection
660 which could cause problems when re-connecting. Affected
663 * Preliminary backup router support for standalone router
664 added. Affected files in silcd/.
666 * Mark server connections in backup router disabled before
667 and after backup protocol. Affected file is
668 silcd/server_backup.c.
670 * Added support for reconnecting to remote server connection
671 even if the protocol fails, and if the configuration wants
672 us to keep trying to connect anyway.
674 Server connection is not allowed to backup router if
675 backup router does not have connection to primary router yet.
677 Affected file is silcd/server.c.
679 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
681 * Added silc_client_udpate_server function to update changed
682 server info. Affected file lib/silcclient/idlist.[ch].
684 * Added check for server entries that are being resolved when
685 notify is received. If being resolved, handle the received
686 notify only after it's resolved so that all notifys are
687 handled in same order as received from the server.
689 Added similar resolver check to channel entries. Every
690 notify that cause resolving of any information that affects
691 channel entry marks the channel entry in waiting state.
692 After whatever resolving is over the waiters are signalled
693 and only then the notifys are handled in the same order
694 as delivered from the server.
696 Affected files are lib/silcclient/idlist.[ch], and
699 * Fixed KILLED notify handling in normal server. Affected
700 file silcd/packet_receive.c.
702 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
703 is locally connected, or was locally connected (but may
704 be detached and connection is not active). Added also
705 SILC_IS_LOCAL for checking this status. Affected files
706 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
707 silcd/server.c and silcd/server_internal.h.
709 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
711 * Don't send or handle TOPIC_SET if topic is already set and
712 is same as being set. Affected files silcd/command.c and
713 silcd/packet_receive.c.
715 * Fixed CMODE change rights checking to work correctly when
716 removing modes by operator. Affected file is
719 * Fixed some handling with New Channel packet in router and
720 fixed some CMODE_CHANGE notify handling in server and router.
721 Affected file is silcd/packet_receive.c.
723 * Changed "disconnect" client operation to include the
724 reason of the disconnection and optional disconnection
725 message. Affected file lib/silcclient/silcclient.h.
727 * Made the compilation of lib/contrib/ stuff conditional.
728 Affected files configure.in.pre, lib/contrib/Makefile.am.
730 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
732 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
733 to the sender of the notify too, to avoid situation where two
734 notifys are in the network at the same time going to oppsite
735 directions. Affected file silcd/packet_receice.c.
737 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
739 * Delete the client from channel even if the cilent->id is
740 NULL. It was possible that client was deleted without
741 removing from channels (theoretically at least). Affected
742 file silcd/server.c and silcd/server_util.c.
744 * Free the client data too when resuming is not successful.
745 Affected file silcd/packet_receive.c.
747 * Merged some code from c0ffee's silc-plugin. Affected files
748 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
750 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
751 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
752 to the primary router connection, the other one returns
753 TRUE if packet must be broadcasted to network.
755 * All notifys that are destined to primary router (to network)
756 are now automatically sent to backup routers even if the
757 router is standalone (and has backup router). Affected files
760 * Added --without-irssi and --without-silcd configuration
761 options for disabling the compilation of these applications.
762 Affected file configure.in.pre and prepare.
764 Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
766 * Implemented SILC_STRING_BMP and SILC_STRING_UNIVERSAL for
767 UTF-8 encoding and decoding. Added also new encodings
768 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
770 Added also SILC_STRING_LANGUAGE which is language and charset
771 specific encoder and decoer for those platforms that support
772 iconv(). It can convert the UTF-8 to and from the locale
773 specific character set.
775 Affected file lib/silcutil/silcstrutil.[ch].
777 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.
779 * Added function silc_get_command_name to the file
780 lib/silcutil/silcutil.[ch].

787 * Save the channel passphrase when received succesful JOIN
788 command reply from router, on normal server. Otherwise
789 joinig +a channels from normal server is not possible.
790 Affected file silcd/command.c.
792 * Fixed a bug in TOPIC_SET notify handling. The notifier
793 may be other than client too, like server or channel.
794 It expected it to always be only client and ignored the
795 notify. Affected file silcd/packet_recieve.c.
797 * Removed some (unnecessary) debug printing from
798 lib/silccore/silcid.c and lib/silccore/silcargument.c.
800 * Do not force CMODE_CHANGE when server is announcing new
803 Router announces stuff only after server reannounces channel
804 after CHANNEL_CHANGE notify.
806 These fixes optimizes the announcing procedure, and perhaps
807 fixes some problems too. Affected file silcd/packet_receive.c.
809 * Fixed SERVER_SIGNOFF sending to local clients. It was
810 totally broken and sent the notify to all local clients,
811 instead of only to those that was on same channel as the
812 signing off clients. Affected file silcd/server_util.c.
814 * Added -D option to server. It can be used to give debug
815 level. The levels are from 0 - 99, and are predefined for
816 smooth server debugging. (see silcd.c for the predefined
817 levels). Affected file silcd/server.c.
819 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
821 * Fixed a bug in Irssi SILC client to close the connection
822 properly when disconnecting from server. Affected file
823 irssi/src/silc/core/client_ops.c.
825 Tue Jun 18 17:14:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
827 * When authenticating as founder during JOIN command, check
828 that the one authenticating becomes the only founder on the
829 channel. Affected file silcd/command.c.
831 * Better checking for founder mode setting when CUMODE_CHANGE
832 notify is received. Affected file silcd/packet_receive.c.
834 * Close all connections when shutting down the server by sending
835 DISCONNECT packet. Close all listeners too when shutting
836 down the server. Affected file silcd/server.c.

839 calling the "disconnect" client operation. Affected file
840 lib/silcclient/client.c.
842 * Handle local errors correctly during resuming. Affected
843 file lib/silcclient/client.c.

869 * Added SILC_MESSAGE_FLAG_UTF8 to the protocol specs and the
870 core library, and implemented it. All textual messages SHOULD
871 use this flag and the message MUST be UTF-8 encoded.
872 All text messages sent by Irssi SILC client are now UTF-8
873 encoded (regardless whether the terminal supports UTF-8 or not).
874 Affected files are lib/silccore/silcchannel.h,
875 irssi/src/silc/core/silc-servers.c, silc-channels.c and

910 that there isn't anyone else with founder mode on the channel.
911 The one that authenticated will become founder and anyone
912 else is demoted. Affected file silcd/command.c.
914 * Added error printing of any error that has occurred during
915 any command in client library. Affected file is
916 irssi/src/silc/core/client_ops.c.

964 Mon Jun 10 09:28:21 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
966 * Made the private key generation after expiration optional.
967 If not created after expiration the old key will re-expire
968 at a later time (and thus key pair is not necessary to
969 change). Affected file irssi/src/silc/core/clientutil.c.
971 Sun Jun 9 18:58:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

1580 * Deprecated all administrative commands from SILC protocol
1581 since they are highly implementation specific commands.
1582 Updated protocol specs. Moved the old commands in
1583 implementations to private range of command types. Affected
1584 files are silcd/command.c, lib/silcclient/command.c and
1585 lib/silcclient/command_reply.c. Protocol TODO #8.
1587 * Fixed a bug in server where sending unknown command crashes
1588 the server. Affected file silcd/command.c.
1590 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1592 * Added SILC_PROTOCOLVERSION macro to check protocol version
1593 of a socket connection. The affected file is
1594 lib/silcutil/silcsockconn.h.
1596 * Added better error logging in rekey protocol. Affected file
1599 * Do not check public key types in SKE during rekey. Affected
1600 file lib/silcske/payload.c.
1602 * Fixed the rekey protocol with PFS, which was totally broken.
1603 Affected file silcd/protocol.c.
1605 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1607 * Some client implementations quit network by doing first LEAVE
1608 and then immediately SIGNOFF (like Bombyx). We now do check
1609 after a short time after LEAVE notify and check whether the
1610 client is still valid after LEAVE, and if not we remove it from
1611 cache. Affected file is lib/silcclient/client_notify.c.
1613 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1615 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1616 it's good not to have security holes here.
1618 * Fixed a negative refcount situtuation for the config context.
1619 Affected file is silcd/serverconfig.c.
1621 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1623 * ROBOdoc documented lib/silcutil/silcutil.h.
1625 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1627 * Optimized even more the SilcPacketContext structure. Now
1628 totally saved 16 bytes of memory per context after optimization.
1629 Affected files are lib/silccore/silcpacket.[ch].
1631 * Made strict checks for valid SILC IDs. Affected file is
1632 lib/silccore/silcid.c.
1634 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1636 * Changed the object argument for silc_cipher_register,
1637 silc_hash_register, silc_hmac_register and silc_pkcs_register
1638 to const. Affected files are lib/silccrypt/silccipher.[ch],
1639 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1641 * Changed the silc_get_username and silc_get_real_name to
1642 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1644 * Fixed the Irssi SILC Client to use the silc_get_username and
1645 silc_get_real_name insted of glib routines since the glib
1646 routines only corrupt stack. Fixes the Irssi SILC to work in
1647 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1649 * Fixed the Irssi to not use g_get_home_dir since it crashes
1650 or returns garbage on cygwin and corrupts stack. Added function
1651 get_home_dir to Irssi routines. Affected files are
1652 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1654 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1656 * Made some structure optimizations. SFTP memory FS MemFSEntry
1657 entry structure. Optimized SilcTask structure. Optimized
1658 SilcPacketContext structure.
1660 Affected files lib/silcsftp/sftp_fs_memory.c,
1661 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1663 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1665 * And yet again reverted back the config thing since Johnny
1666 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1669 * Fixed memory leaks from config object. Affected files are
1670 silcd/serverconfig.[ch].
1672 * Added support for adding new connections to the server in rehash.
1673 After rehash they take effect.
1675 Added support for changing the maximum allowed connections in
1676 rehash. The number can grow but going smaller is not supported.
1678 Added function silc_server_num_sockets_by_remote to the
1679 silcd/server_util.[ch].
1681 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1683 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1685 * Added preliminary checking during config parsing for a valid
1686 public/private key and removed further checks in the code.
1687 Affected files are silcd/serverconfig.[ch], server.c.
1689 * Moved functions silc_server_drop() and silc_server_daemonise()
1690 from server.c to silcd.c since they are stricly related to
1691 the application activity.
1693 * Reverted a small part of the automatic ref/unref since
1694 it caused a double unref in some situations. Affected
1695 files are silcd/silcd.[ch], server.c, serverconfig.c.
1697 * Added some .cvsignore files in the lib directory.
1699 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1701 * Fixed silc_net_gethostbyaddr to correctly resolve by
1702 address. Affected file lib/silcutil/silcnet.c.
1704 * Fixed the notify relaying to client. The HMAC to be used
1705 with relayed packets ws wrong and caused decryption failure
1706 at the client end. Affected file is silcd/packet_receive.c.
1708 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1710 * Created new branch silc_protocol_1_0_branch.
1712 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1714 * Changed the silc_server_config_* routines to be SilcServer
1715 independent. They are now officially application specific code
1716 and not part of generic server implementation. Affected files
1717 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1719 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1721 * Added automatic referencing of config context in the
1722 silc_server_config_alloc, and automatic unreferencing in the
1723 silc_server_config_destroy. Affected files are
1724 silcd/serverconfig.[ch], silcd/silcd.c.
1726 * Fixed the silc_log_quick handling in the logging routines.
1727 It didn't log quickly when it was TRUE. Affected file is
1728 lib/silcutil/silclog.c. Also the flush delay was set even
1729 if it was 0 in config file. Affected file is
1730 silcd/serverconfig.c.
1732 * Added support for changing key pair of the server in rehash.
1733 Affected file silcd/server.c.
1735 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1737 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1738 too early, before getting the channel entry. Affected file
1739 is silcd/packet_receive.c.
1741 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1743 * Added functions silc_server_config_[ref/unref], these are used
1744 to prevent that the config object is destroyed.
1746 No longer directly affect global variables silc_log_quick and
1747 silc_log_delay, they are first cached inside the config object
1748 and then applied with silc_server_config_setlogfiles().
1750 silc_server_config_set_defaults() is now internal to
1751 serverconfig.c, there are no reasons to show this internal stuff
1754 Affected files are silcd/serverconfig.[ch].
1756 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1757 fprintf's to stderr, since some code may be executed again after
1758 the server went into the background. Affected files are
1761 * Added rehash support. Added function silc_server_rehash() that
1762 will perform all the basic tasks of the rehashing procedure.
1764 * Added command line option `-x, --hexdump'. This will enable the
1765 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1766 The option `--hexdump' implies `--debug'.
1768 * Fixed a bad bug in the logging APIs (silcutil library) where
1769 the application would crash after calling silc_log_reset_all().
1771 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1773 * Fixed the KICKED notify handling in client library to
1774 correctly remove the channel and all entries from the
1775 channel when I was kicked. This bug crashed the client.
1777 Fixed yet another but in KICKED notify handling to remove
1778 the kicked client correctly from the channel.
1780 Affected file is lib/silcclient/client_notify.c.
1782 * Fixed a minor bug in looking up correct client entry
1783 in KICKED notify in server. Affected file is
1784 silcd/packet_receive.c.
1786 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1787 sources correctly to distribution. Fixes --with-gmp option.
1789 * Removed the manual rehashing from ID Cache, and changed it
1790 to use the SILC Hash Table's auto rehash feature. Affected
1791 file is lib/silccore/silcidcache.c.
1793 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1795 * Fixed a bug in the silc_client_nickname_format function that
1796 handles the multiple same nickname formatting. Two clients
1797 with same nickname caused problems after the first one left
1798 and rejoined. It didn't format the nickname correctly.
1799 Affected file is lib/silcclient/idlist.c.
1801 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1803 * Don't change the topic if olod topic is same as new one.
1804 Affected file is silcd/packet_receive.c.
1806 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1808 * Added cross-reference support to the SILC Documentation
1809 generator. All types across all HTML files are now cross-
1810 referenced. Affected files util/robodoc/generator.c and
1811 scripts/silcdoc/silcdoc.
1813 * Added file lib/silcutil/silctypes.h to include all the
1814 arithmetic type definitions and some macros. Removed
1815 includes/bitmove.h and moved macros to silctypes.h.
1817 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1819 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1821 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1823 * Added `type' argument to silc_id_payload_parse_id function which
1824 now returns the type of the ID to the sent pointer. Affected
1825 file is lib/silccore/silcid.[ch].
1827 * Added check for CMODE_CHANGE notify type that mode change is
1828 allowed by the sender. Affected file silcd/packet_receive.c.
1830 * Added check for CUMODE_CHANGE notify type that mode change is
1831 allowed by the sender. Affected file silcd/packet_receive.c.
1832 Added the ID type as CUMODE_CHANGE notify type as argument
1833 to the `notify' client operation. Affected files are
1834 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1836 * Added function silc_client_add_server to the client library.
1837 Added support for resolving also channel and server info when
1838 received unknown entity in notify packet. Affected files are
1839 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1841 * Added function silc_command_get_status to return the command
1842 status from the command reply's argument payload. Affected files
1843 are lib/silccore/silccommand.[ch].
1845 * Added check for KICKED notify type that the kicking is
1846 allowed by the client. Affected file silcd/packet_receive.c.
1848 * Created function silc_get_input which can be used to get input
1849 (echo on or off) from user on command line. Affected files are
1850 lib/silcutil/silcutil.[ch].
1852 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1854 * Optimized silc_server_packet_relay_to_channel function.
1855 Added new function silc_channel_message_payload_encrypt which
1856 can be called directly if channel message payload needs to
1857 be encrypted and is already encoded (no need to call _encode
1858 function). Packet relaying is now done by router without any
1859 extra memory allocations. Affected files are
1860 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1861 silcd/packet_send.c.
1863 * Fixed the INVITE notify handling. It took wrong arguments
1864 as invite list and invite delete. Affected file is
1865 silcd/packet_receive.c.
1867 * Added check for TOPIC_SET notify type that the topic change is
1868 allowed by the client. Affected file silcd/packet_receive.c.
1870 * Added check for INVITE notify type that inviting is allowed by
1871 the client. Affected file silcd/packet_receive.c.
1873 * Changed the silc_server_client_on_channel to return the
1874 SilcChannelClientEntry as well. Moved the function
1875 silc_server_check_cmode_rights to server_util.[ch].
1876 Affected files are silcd/server_util.[ch], silcd/command.c.
1878 * Added function silc_server_check_umode_rights to check whether
1879 changing client's user mode is allowed. Added check for
1880 UMODE_CHANGE notify type that the umode change is allowed
1881 by the client. Affected files are silcd/server_util.[ch],
1882 silcd/packet_receive.c and silcd/command.c.
1884 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1886 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1887 ID length. It ignored that ID can be IPv6 based as well.
1888 Affected file lib/silccore/silcpacket.h.
1890 * Fixed the silc_id_id2str and silc_id_str2id to take the
1891 IPv6 address offset's into consideration. Affecte file is
1892 lib/silccore/silcid.c.
1894 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1896 * Fixed the internal Unix scheduler functions to check for
1897 NULL context they may receive. The affected file is
1898 lib/silcutil/unix/silcunixschedule.c.
1900 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1902 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1903 can specify different directory with --home command line
1904 parameter. Affected files irssi/src/silc/core/client_ops.c,
1907 * SILC-specific commands aren't now executed if the active server
1908 isn't of SILC-type, so there won't be problems with having
1909 IRC and SILC protocol support in same client. Affected files
1910 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1913 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1915 * Improved the signal support in SILC Schedule. Added new
1916 function silc_schedule_signal_call which is used by application
1917 to mark a signal to be called. It is now safe to perform
1918 any kind of tasks in signal callbacks since it is guaranteed
1919 that the application specified signal callback is called
1920 after the signal is over. Affected files are
1921 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1923 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1925 * Added `name' field to SilcChannelPrivateKey to represent
1926 application given name for the key. Moved also the context from
1927 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1928 Added the `name' argument also to the function
1929 silc_client_add_channel_private_key.
1931 Added function silc_client_current_channel_private_key to set the
1932 current channel private key in use.
1934 Added "change" command to KEY command which can be used to change
1935 the current channel private key. Bound the command also to
1936 alt+K (Alt+Shift+k).
1938 Also affected files lib/silcclient/client_channel.c,
1939 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1941 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1943 * Added silc_rng_get_byte_fast function in to the
1944 lib/silccrypt/silcrng.[ch].
1946 * Changed the interface of silc_packet_assemble and the
1947 silc_packet_send_prepare. If silc_packet_assmble is now
1948 called the application does not call silc_packet_send_prepare
1949 because the library will call it automatically. These
1950 interfaces now also return a reference to the outgoing buffer
1951 which includes the assembled packet, which the application can
1952 use to encrypt the packet.
1954 Affected files are lib/silccore/silcpacket.[ch],
1955 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1956 silcd/packet_send.c, server_backup.c and packet_receive.c.
1958 * Fixed a packet sending bug on very high load, where outgoing
1959 packet queue wasn't handled correctly and packets got corrupted.
1960 Affected files are lib/silcutil/*/silc*sockconn.c,
1961 lib/silcclient/client.c and silcd/server.c.
1963 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1965 * Added macro SILC_PACKET_DATALEN which can be used during
1966 packet assembling to check whether the data to be added to
1967 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1968 len is truncated until it fits it.
1970 Added checks for maximum length of channel message payload and
1971 private message payload also.
1973 Added checks for maximum packet length in server and in
1976 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1977 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1978 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1979 lib/silcclient/client_prvmsg.c.
1981 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1983 * Added silc_server_packet_queue_purge call to the
1984 silc_server_disconnect_remote to assure that all data in the
1985 queue before disconnecting is sent to the network. Affected
1986 file silcd/server.c.
1988 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1990 * Added the deleting of server's own ID cache entry to the
1991 silc_server_free function. Free also everything else that
1992 has been allocated in silc_server_init. The affected file
1995 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1997 * Added functions silc_parse_version_string, silc_version_to_num,
1998 and silc_ske_parse_version to parse SILC protocol style version
1999 strings. Affected files lib/silcutil/silcutil.[ch] and
2000 lib/silcske/silcske.[ch].
2002 * Added new configuration params: version_protocol, version_software
2003 and version_software_vendor to specify what version the remote
2004 host must at least be to be able to connect to server. The vendor
2005 string can be regex matched too. Added new function
2006 silc_server_connection_allowed to check maximum number of allowed
2007 connections, and allowed versions for incoming connections.
2008 Affected files are silcd/server.c, server_util.[ch] and
2011 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2013 * Added preliminary support for signals in scheduler. The
2014 signals we care about are now blocked always when the scheduler
2015 is locked. This way we can synchronise the use of signal with
2016 scheduler. It is guaranteed that when signal occurs the scheduler
2017 is not locked, and thus new tasks can be safely added to the
2020 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
2021 to silc_schedule_internal_init and silc_schedule_internal_uninit.
2022 Added new platform specific routines
2023 silc_schedule_internal_signals_[un]block and
2024 silc_schedule_internal_signal_[un]register.
2026 Added new functions to SILC Schedule API:
2027 silc_schedule_signal_[un]register. Each signal that application
2028 is going to use should be registered to the scheduler.
2030 Affected files are lib/silcutil/silcschedule.[ch],
2031 lib/silcutil/*/silc*schedule.c.
2033 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2035 * Check for unauthenticated client and server in the
2036 silc_server_new_client and silc_server_new_server functions.
2037 Affected file silcd/packet_receive.c.
2039 * Added function silc_string_is_ascii to check whether given
2040 string is 7-bit ASCII string. Affected files are
2041 lib/silcutil/silcutil.[ch].
2043 * Added function silc_id_is_valid_server_id into the
2044 silcd/serverid.c and added checking for valid Server ID's in
2045 silc_server_new_server. The Server ID must always be based
2046 on the server's public IP address.
2048 * Added logging of DISCONNECT packet message in the server.
2049 Affected file silcd/server.c.
2051 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2053 * Changed all library interfaces that use Global RNG to also
2054 accept SilcRng as argument. Affected files are
2055 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
2056 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
2057 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
2058 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
2059 lib/silccrypt/rsa.c.
2061 * Added function silc_pkcs_generate_key to the
2062 lib/silccrypt/silcpkcs.[ch] for applications so that they
2063 don't need to do pkcs->pkcs->init calls anymore.
2065 * Remove SilcSocketConnection from the SFTP API since it really
2066 wasn't needed there. The application has the information
2067 saved in its contexts anyway and the SFTP layer doesn't need
2068 know about it. Affected files lib/silcsft/silcsftp.h and
2069 lib/silcsftp/sftp_[server/client].c.
2071 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
2072 The SilcSimContext is not SilcSim.
2074 * Fixed possible buffer overflows in silc_id_render in the
2075 lib/silcutil/silcutil.c.
2077 * On EPOC the global crypto module lists are not used at all
2078 in the crypto library. Added support for using the constant
2079 algorithm list on EPOC. Affected files are
2080 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
2083 * Fixed the handling of third parameter of KICKED notify, since
2084 it was mistakenly updated to SILC Protocol 1.0 even though it
2085 is to be included in 1.1. Since it is not in 1.0 it is not
2086 mandatory, and this fix now handles it only if it is provided,
2087 and it is not error if it is not provided. Affected file
2088 lib/silcclient/client_notify.c.
2090 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2127 file lib/silcutil/silcutil.[ch].
2129 * Added support for specifying multiple public keys for Client
2130 connection section in server configuration file. This makes it
2131 possible to accept multiple public keys from same host, or to
2132 make a section that accepts any incoming host, and have the
2133 accepted public keys listed in the section.
2135 Added functions silc_sever_[find/get]_public_key, added the
2136 support for this actually to all connection sections but only
2137 the Client section is currently allowed to specify multiple
2140 Affected files are silcd/server.c, server_internal.h,
2141 command.c, protocol.c, server_util.[ch], packet_receive.c.

2160 from single host, by checking also the type of the connection.
2161 Fixed also the comparison of number of connections and number
2162 of allowed connections. Affected files are silcd/server.c,
2165 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2244 application does not need to define them. Affected file
2245 includes/silcincludes.h.
2247 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
2248 old name went against naming convention. Applications now
2249 include "silcclient.h" instead of "clientlibincludes.h".
2250 Removed includes/clientlibincludes.h, it is redundant now.
2252 * Renamed includes/version.h to silcversion.h.
2254 * Added really preliminary support for OS/2 into the util
2255 library. Only thread & mutex API is implemented, others
2256 are still to be implemented. Created the lib/silcutil/os2/
2257 directory. Created also file includes/silcos2.h.

2290 * Added `user_count' to the SilcChannelEntry which now tells the
2291 number of users on the channel. The user count is now saved
2292 in normal server of global channels as well. Affected files
2293 silcd/server.c, idlist.h, packet_receive.c and command.c.
2295 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
2296 include file utility functions.
2298 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
2299 instead of calling directly OS routines.
2301 * Fixed NICK change printing in Irssi SILC Client. Fixed
2302 KICKED notify printing in Irssi SILC Client. Affected file
2303 irssi/src/silc/core/client_ops.c.

2311 * ROBOdoc documented the lib/silcske/silcske.h, and improved
2312 the SKE interface a bit.
2314 * Fixed padding problem in PKCS#1. The padding was not actually
2315 random since the random number generator was used incorrectly.
2316 This security bug affects only when encrypting with PKCS#1, and
2317 it is not currently used at all in SILC. SILC only use signing
2318 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
2320 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2381 Affected files irssi/src/silc/core/silc-core.c,
2382 irssi/src/fe-text/silc.c.
2384 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2386 * Added new configuration options and blocks:
2387 keepalive_secs, reconnect_count, reconnect_interval,
2388 reconnect_interval_max, reconnect_keep_trying and
2389 require_reverser_lookup. Added ConnectionParam block, and
2390 implemented the connection parameters when connecting as
2391 initiator and when accepting connections as responder.

2403 the connection configuration object from the SilcServerConnection
2404 object instead of finding it during the connecting phase.
2405 Added the configuration object to SilcServerConnection struct.
2406 Affected files silcd/server_internal.h, server.c.
2408 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2410 * Add the client on channel after it was resolved at the
2411 channel message receiving, and it was not already on the
2412 channel. Affected file lib/silcclient/client_channel.c.
2414 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2430 authentication to be set at the same time.
2432 Added `prefer_passphrase_auth' setting in config file which
2433 can be used to set to prefer passwd auth if both passwd and
2434 public key is set. If not set, public key is preferred.
2435 This has effect only when being initiator (responder will try
2438 Added support for authentication with passphrase and public key
2439 at the same time. The passphrase is tried first always since
2440 it is faster to check.
2442 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2444 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2490 * Fixed the file transfer's key agreement payload to include
2491 zero port also if the hostname is NULL because it could not
2494 Call file transfer monitor callback now also if error occurs
2495 during key agreement protocol.
2497 Changed the silc_client_file_send interface to return the
2498 SilcClientFileError instead of session id. The session ID
2499 is returned into pointer provided as argument.

2516 file lib/silcutil/silclog.c.
2518 * Fixed the channel message payload decryption in the function
2519 silc_channel_message_payload_decrypt to not modify the original
2520 buffer before it is verified that the message decrypted
2521 correctly. Otherwise, next time it is called with correct
2522 channel key it won't encrypt since the payload is corrupted.
2523 Affected file lib/silccore/silcchannel.c.
2525 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2537 * Fixed a bug in hash table internal routine for traversing
2538 the table with foreach callback. The current entry may
2539 become invalid in the callback but it was referenced after
2540 the callback returned.
2542 Do not allow auto rehashing of hash table during the
2543 silc_hash_table_foreach operation, for same reasons as it is
2544 not allowed for SilcHashTableList. Affected files are
2545 lib/silcutil/silchashtable.[ch].
2547 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2549 * Defined DLLAPI into silcincludes.h and silcwin32.h for

2553 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2555 * Fixed private message handling. It used some old code that
2556 caused the client to crash. Affecte file is
2557 lib/silcclient/client_prvmsg.c.
2559 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2561 * Added function silc_client_add_channel,
2562 silc_client_replace_channel_id, and removed functions
2563 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2564 from client library.
2566 * Added cross reference of the joined channels to the
2567 SilcClientEntry, and changed the SilcChannelEntry's
2568 users list to SilcHashTable. The affected files are
2569 lib/silcclient/idlist.[ch].
2571 * Fixed a bug in hash table tarversing. While the hash table
2572 is traversed with SilcHashTableList the table must not be
2573 rehashed. It is now guaranteed that auto rehashable tables
2574 are not rehashed while tarversing the list. Also defined that
2575 silc_hash_table_rehash must not be called while tarversing
2576 the table. Added function silc_hash_table_list_reset that must
2577 be called after the tarversing is over. The affected files are
2578 lib/silcutil/silchashtable.[ch].
2580 * Changed all hash table traversing to call the new
2581 silc_hash_table_list_reset in server and in client library.
2583 * Added function silc_client_on_channel to return the
2584 SilcChannelUser entry if the specified client entry is joined
2585 on the specified channel. This is exported to application as
2586 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2588 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2591 server. The notify for mode change must be sent always and
2592 not only if !cmd->pending. Affected file silcd/command.c.
2594 * Fixed the WHOWAS command's reply sending to support the
2595 lists correctly. Affected file silcd/command.c.
2597 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2599 * When sending JOIN command to router for processing the
2600 sender's old command identifier was not saved back to the
2601 sender's command context, fixed now. The affected file is
2604 * Create the key in JOIN command of the router did not return
2605 the channel key, added check for this. Affected file is
2608 * Fixed a channel ID update bug in JOIN command reply. Do
2609 not directly upgrade the ID but call the function
2610 silc_idlist_replace_channel_id if the ID was changed.
2611 Affected file silcd/command_reply.c.
2613 * Fixed memory leaks from command calling if it would fail.
2614 Affected file silcd/command.c.
2616 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2618 * Applied patches from cras:
2620 Memory leak fixes around libaries, irssi window resize fix,
2621 new silclist.h and silcdlist.h, all extern inline changed to
2624 * Removed dotconf from lib/dotconf, not needed anymore.
2626 * Removed TRQ from lib/trq, not needed anymore.
2628 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2629 with server connections. Later this will be configurable
2630 in config file after new config file is done. Affected file
2633 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2635 * Fixed a crash in server related to channel announcements.
2636 Affected file silcd/server.c.
2638 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2640 * Fixed memory leaks in silc_server_create_new_channel*
2641 functions. Affected file silcd/server.c.
2643 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2644 which ID was changed. This way the router will send the
2645 user list for the channel again, and server won't be in
2646 desync in some rare circumstances. Affected file is
2647 silcd/packet_receive.c.
2649 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2651 * Check for NULL socket pointer in the function
2652 silc_server_packet_send_to_channel_real. Affected file
2653 silcd/packet_send.c.
2655 * Fixed the BAN notify handling to correctly remove ban
2656 list. Affected file silcd/packet_receive.c.
2658 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2660 * Fixed some header addition to Toolkit distribution in
2661 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2663 * Added lib/silcclient/client_ops_example.h as an template
2664 file for application programmers to quickly start using
2665 the SilcClientOperation functions in their application.
2666 Updated the lib/silcclient/README as well to tell about this
2667 nice file made available.
2669 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2671 * Call silc_server_remove_from_channels when removing client
2672 entry when NO_SUCH_CLIENT_ID was received. Affected file
2673 is silcd/command_reply.c.
2675 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2677 * Added server & router operator statistics updating. Affected
2678 file silcd/packet_receive.c and silcd/command.c.
2680 * Fixed the SERVER_SIGNOFF notify handling on normal server
2681 not to save the history information for clients. Same was
2682 fixed earlier in remove_clients_by_server function, but not
2683 here. Affected file silcd/packet_receive.c.
2685 * Raised the default connection-retry count from 4 to 7 in
2686 server. Affected file silcd/server.h.
2688 * Cancel any possible reconnect timeouts when we start the
2689 key exchange. Affected file silcd/server.c.
2691 * Do not reconnect on connection failure when SCONNECT was
2692 given. Affected files silcd/server.[ch].
2694 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2696 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2698 * Fixed the NICK command to always give the unformatted
2699 nickname to the one giving the NICK command. If unformatted
2700 nickname is cached already it will be formatted and the
2701 local entry will always get the unformatted nickname.
2702 Affected file lib/silcclient/idlist.c.
2704 * Fixed some double frees from client library commands.
2705 Affected file is lib/silcclient/command.c.
2707 * Fixed CUMODE command in server to assure that no one can
2708 change founder's mode than the founder itself, there was a
2709 little bug. Affected file silcd/command.c.
2711 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2713 * Removed the SilcClientCommandDestructor from the client
2714 libary, it is not needed anymore. Affected files are
2715 lib/silcclient/silcapi.h, command[_reply].[ch],
2716 client_notify, idlist.c.
2718 * Fixed GETKEY command to first resolve client, and then
2719 resolve the server only if the client was not found, instead
2720 of resolving both at the same time. Affected file is
2721 lib/silcclient/command.c.
2723 * Added silc_client_start_key_exchange_cb and lookup the
2724 remote hostname and IP address before starting the key
2725 exchange with server. The affected file is
2726 lib/silcclient/client.c.
2728 * The server's public key is now saved using the IP address
2729 of the server and not the servername for the filename.
2730 The hostname public key filename is checked as an fall back
2731 method if the IP address based filename is not found.
2733 Fixed the GETKEY command to save the fetched server key
2734 in correct filename.
2736 Print the remote server's hostname now when new key is
2737 received during connection process. Affected file is
2738 irssi/src/silc/core/client_ops.c.
2740 * Return always our own public key to the client if it asks
2741 for it with GETKEY command. Affected file silcd/command.c.
2743 * Removed the use_auto_addr variable from default config
2744 file since it was in wrong section. Affected file is
2747 * Fixed TOPIC_CHANGE notification to not route it when it
2748 was sent using silc_server_send_notify_to_channel function.
2749 Affected file silcd/command.c.
2751 * Fixed silc_server_send_notify_kicked to send the kicker's
2752 Client ID also, it was missing. Affected files are
2753 silcd/command.c, silcd/packet_send.[ch].
2755 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2757 * Do not save client history information in SERVER_SIGNOFF.
2758 Fixes the bug in normal server that it does not detect
2759 the client becoming valid after the server becomes back
2760 online. Affected file silcd/server_util.c.
2762 * Added `sock_error' field into the SilcSocketConnection
2763 context. When error occurs during socket operation (read
2764 or write) the error is saved. Added also new function
2765 silc_socket_get_error to return human readable socket error
2766 message. Affected files are lib/silcutil/silcsockconn.[ch],
2767 lib/silcutil/unix/silcunixsockconn.c, and
2768 lib/silcutil/win32/silcwin32sockconn.c.
2770 * The server now prints the socket error message in the
2771 signoff for client. Affected file silcd/server.c.
2773 * Fixed the `created' channel information sending from router
2774 to server in JOIN command. Checks now whether the channel
2775 really was created or not and set it according that.
2777 Fixed the JOIN command to use the client entry's current
2778 ID during the joining procedure instead of the one it sent
2779 in the command (it is checked though), since it can change
2780 between the packet processing and command processing, and
2781 would just case unnecessary pain in the client end. Affected
2782 file silcd/command.c.
2784 * Fixed a channel key payload sending to use correct channel
2785 ID when the server was forced to change the channel's ID by
2786 router. Router sent the key payload with the old Channel ID.
2787 Affected file silcd/packet_receive.c.
2789 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2791 * Call silc_server_save_channel_key only if the key payload
2792 was provided in the JOIN command's command reply. Affected
2793 file silcd/command_reply.c.
2795 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2797 * Fixed silc_mp_sizeinbase to return the value correctly with
2798 MPI. Affected file lib/silcmath/mp_mpi.c.
2800 * Fixed the stop_server signal to correctly stop the scheduler
2801 and gracefully stop the server when SIGTERM or SIGINT signals
2802 are received. Affected file silcd/silcd.c.
2804 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2806 * Simple handling of TERM and HUP signals. Also added some log
2807 flushing call around. Affected file is
2810 * Fixed small bugs in silclog.c. Now buffering output will take
2811 effect after 10 seconds since startup: This will ensure that
2812 no important startup messages are lost. Also output redirection
2813 will preserve original format ([Date] [Type] message).
2814 Affected file is lib/silcutil/silclog.c.
2816 * Added two options to the config file, in the logging section:
2817 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2818 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2820 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2822 * Do not print the warning about log files not being initialized
2823 more than once to avoid excess logging. Affected file is
2824 lib/silcutil/silclog.c.
2826 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2827 the SIM copying in make install in Makefile.am.pre.
2829 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2831 * Rewritten silclog APIs. Globally interesting changes follows:
2832 silc_log_set_files() changed to silc_log_set_file().
2833 silc_log_set_callbacks() changed to silc_log_set_callback().
2834 ROBOdoc documented silclog header file.
2835 SilcLogCb now returns bool to wether inihibit the default
2836 handler or not (to keep the old behaviour return always TRUE).
2837 The new APIs should also fix the problem of the
2838 silcd_error.log file that was written in the current directory.
2841 Log files streams will remain opened after silc_log_set_file()
2842 call, means less CPU usage notably on high traffic servers.
2843 File streams are now full buffered, and flushed to the disk
2844 every 5 minutes, lesses HD activity and CPU usage.
2845 Messages can be redirected, allowing admins to configure
2846 one single logfile for all server messages.
2847 the silc_log_quick global variable to activate fast-logging.
2848 Affected files lib/silcutil/silclog.[ch]
2850 * Changed some code to conform new silclog APIs. Affected
2851 files are doc/example_silcd.conf.in, silcd/server.c
2852 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2855 * Fixed a memory leak that could occur in some situations.
2856 Affected file silcd/serverconfig.c.
2858 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2860 * Added the silc_client_del_client to remove the client from
2861 all channels as well. Affected file lib/silcclient/idlist.c.
2863 * Fixed the client library to correctly remove the client
2864 from all channels when the client entry is being destroyed.
2865 Affected file lib/silcclient/client_notify.c, command.c.
2867 * Added auto-nicking support to the client library. If the
2868 applicatio now sets client->nickname it will be sent to the
2869 server after connecting by the library. This way for example
2870 SILCNICK (or IRCNICK) environment variables will have effect
2871 and always change the nickname automatically to whatever
2872 it is wanted. Affected file lib/silcclient/client.[ch].
2874 * Renamed silc_server_command_bad_chars to the
2875 silc_server_name_bad_chars and moved it to the
2876 silcd/server_util.[ch]. Added also new function
2877 silc_server_name_modify_bad to return nickname that
2878 includes bad characters as new nickname without those
2879 bad characters. This check and modify is now used in
2880 silc_server_new_client when the username is initially set
2881 as nickname, so it must be checked to be valid nickname.
2882 Affected file silcd/packet_receive.c.
2884 * The nickname length is now taken from the packet for real
2885 and not trusted to strlen() since it clearly can return
2886 wrong length for nickname including bad characters. This
2887 also applies to channel names. Affected file silcd/command.c.
2889 * Removed the lib/silcsilm/modules directory. Modules are now
2890 compiled into the lib/silcsim. Fixed the copying of the
2891 modules to follow symbolic links in Makefile.am.pre.
2893 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2895 * Fixed silc_string_regexify list creation. Fixes bugs with
2896 BAN and INVITE commands in server. The affected file is
2897 lib/silcutil/unix/silcunixutil.c.
2899 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2901 * Removed the command destructor entirely from the server's
2902 command and command reply routines. It is not needed, and
2903 its usage was buggy and caused crashes. Affected files are
2904 silcd/command[_reply].[ch].
2906 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2908 * Cancel protocol and NULL sock->protocol if timeout
2909 occurred during protocol. Affected file silcd/server.c.
2911 * Cancel protocol timeouts always before calling the final
2912 callback, to assure that after final callback is called
2913 no other state will be called for the protocol anymore.
2914 Affected file silcd/protocol.c.
2916 * Print error log if incoming connection configuration could
2917 not be found. Affected file silcd/server.c.
2919 * Fixed JOIN command to correctly save the founder mode
2920 to the client on normal SILC server, when the channel
2921 was created by the router. Affected file silcd/command.c.
2923 * Fixed LIST command (hopefully) to send correct reply
2924 packets. Affected file silcd/command.c.
2926 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2928 * The silc_packet_receive_process now returns FALSE if the
2929 read data was invalid packet, and TRUE if it was ok.
2931 The server now checks that if unauthenticated connection
2932 sends data and its processing fails the server will close
2933 the connection since it could be a malicious flooder.
2935 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2937 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2939 * Make sure the warning about error opening a log file is
2940 printed only once and not everytime it fails (produces
2941 too much useless log). Affected file lib/silcutil/silclog.c.
2943 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2945 * Made the silc_server_daemonise() function more readable.
2946 Affected file silcd/server.c.
2948 * Pid file is now optional, the user may comment it out from
2949 the config file. Removed define SILC_SERVER_PID_FILE, we
2950 don't need a default any longer. Affected file
2951 configure.in.pre, lib/Makefile.am.pre.
2953 * Make some use of the pid file. The server now dies at startup
2954 if it detects a valid pid file on his path. The server would
2955 die anyway in this circumstance, because of the bind() failure.
2956 Affected file silcd/silcd.c.
2958 * No longer compiling lib/dotconf.
2960 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2962 * Fixed JOIN command parsing not to crash. Affected file
2963 lib/silcclient/command.c.
2965 * Fied the NICK_CHANGE notify to add the new client entry
2966 even it is resolved. This removes an <[unknown]> nick
2967 thingy bug in the client. Affected file is
2968 lib/silcclient/client_notify.c.
2970 * Do not try to allocate 0 bytes (efence does not like it)
2971 in lib/silccore/silccomand.c when encoding payload.
2973 * Do not take IRCNICK as nickname in Irssi SILC client since
2974 it is not possible to set nickname before hand connecting
2975 the server (TODO has an entry about adding auto-nicking
2978 * Changed the silc_server_command_pending to check whether
2979 there already exists an pending entry with the specified
2980 command, command identifier and pending callback. This is
2981 to fix IDENTIFY and WHOIS related crashes that may register
2982 multiple pending commands with same identifier. Affected
2983 file silcd/command.c.
2985 * Fixed the server to reconnect to the router even if it
2986 was already reconnecting and EOF was received. This to
2987 fix a possibility that the server wouldn't ever try to
2988 auto-reconnect to the router. Affected file silcd/server.c.
2990 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2992 * Fixed the server's password authentication to use the
2993 length of the locally saved password, and not the one
2994 sent in the packet. Affected file silcd/protocol.c.
2996 * Fixed same password authentication problem in the
2997 Authentication Payload handling routines in
2998 lib/silccore/silcauth.c.
3000 * Yet another password authentication problem fixed with
3001 channel password handling in silcd/command.c.
3003 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3005 * If first character of string in silc_parse_userfqdn is '@'
3006 then do not parse it. Affected file is
3007 lib/silcutil/silcutil.c.
3009 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3011 * Fixed minor bug in IDENTIFY command reply sending, which
3012 caused various weird problems during JOIN when it was
3013 resolving names for users. Affected file silcd/command.c.
3015 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3017 * Fixed the IDENTIFY command reply sending to chech better valid
3018 clients. It was possible to send incomplete list of replies.
3019 Affected file silcd/command.c.
3021 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3023 * Added silc_client_command[s]_[un]register functions now to
3024 dynamically register the commands in client library. Removed
3025 the static table of commands. This allows the client library
3026 to call commands without causing the application to know about
3027 what commands library has called.
3029 Removed the INFO command reply kludge to detect when the command
3030 was called by library. Now library use its own command reply
3031 function for INFO command.
3033 Added function silc_client_command_call to call a command.
3034 Application can use it to call command, not access the structure
3037 Now all commands that are sent by the client library (not
3038 explicitly sent by application) use own command reply functions.
3040 Affected files around lib/silcclient/ and in
3041 irssi/src/silc/core/.
3043 * Fixed the WHOIS command reply sending to chech better valid
3044 clients. It was possible to send incomplete list of replies.
3046 Fixed the WHOIS and IDENTIFY to send the request to router
3047 if normal server did not do it and did not find any results.
3049 Affected file silcd/command.c.
3051 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3053 * Moved the internal data from SilcClient context into its
3054 own file, not accesible to application. Affected files
3055 lib/silcclient/client.h and lib/silcclient/client_internal.h,
3056 and other files in client library.
3058 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3060 * Added doc/examples installation target in Makefile.am.pre.
3063 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3065 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
3066 commands the found client entry will be removed from the
3067 cache, after notifying application about the error. Affected
3068 file lib/silcclient/command_reply.c.
3070 * Changed the /MSG to check for exact nickname user gave, and
3071 not let `nick' match `nick@host' if it is only one found. Now,
3072 user must type the exact nickname (like nick@host2) even if
3073 there are no more than one same nicks found. This is to avoid
3074 a possibility of sending nickname to wrong nickname since
3075 `nick' could match `nick@host'. Affected file is
3076 irssi/src/core/silc-servers.c.
3078 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3080 * Do not print "you are now server operator" or similar when
3081 giving /away command. Affected files are
3082 irssi/src/silc/core/client_ops.c, silc-servers.h.
3084 * Made the silc_server_command_pending_error_check to send
3085 the same command reply payload it received back to the
3086 original sender of the command. This way all arguments
3087 that was received by the server will be received by the
3088 client too. Affected file silcd/command.c.
3090 * Added the silc_idcache_add to return the created cache entry
3091 to a pointer. Affected file lib/silccore/silcidcache.[ch].
3093 * Add global clients to expire if they are not on any channel.
3094 This is because normal server will never know if they signoff
3095 if they are not on any channel. The cache expiry will take
3096 case of these entries. This is done by normal servers only.
3097 The affected files are silcd/command_reply.c,
3098 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
3100 * If server receives invalid ID notification for WHOIS or
3101 IDENTIFY and the ID exists in the lists, it is removed.
3102 Affected file silcd/command_reply.c.
3104 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
3105 in client then client entry that it matches is searched and
3106 the nickname is printed on the screen for user. Affected
3107 file irssi/src/silc/core/client_ops.c.
3109 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3111 * Use cache entry expire time in the LIST command reply to
3112 purge old entries from the cache after the LIST command
3113 reply has been received. This way we don't have non-existent
3114 entries in the cache for too long. Affected file is
3115 silcd/command_reply.c.
3117 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3119 * If we are normal server, and we've not resolved client info
3120 in WHOIS or IDENTIFY from router, and it is global client,
3121 we'll check whether it is on some channel. If it is not
3122 then we cannot be sure about its validity and will resolve it
3123 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
3124 file silcd/command.c.
3126 * Search channel by name (if possible) rather than by ID
3127 in IDENTIFY command's command reply. Affected file is
3128 silcd/command_reply.c.
3130 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3132 * Distribute to the channel passphrase in CMODE_CHANGE notify.
3133 Updated specs and implemented it. Affected file silcd/command.c,
3134 silcd/packet_send.c and silcd/packet_receive.c.
3136 * Implemented the <founder auth> payload handling in the JOIN
3137 command. If provided all conditions for channel joining
3138 except requirement to provide correct passphrase can be
3139 overrided by the channel founder. Updated the protocol specs.
3140 Affected file silcd/command.c.
3142 Added support for founder auth in JOIN command in client
3143 library. Fixed the parsing of the JOIN command now to support
3144 all options as they should be. The affected file is
3145 lib/silcclient/command.c.
3147 * Optimized the WHOIS and IDENTIFY commands to send the request
3148 to router only if it includes nicknames or other names. If
3149 they include only IDs then check the local cache first before
3150 routing. Affected file is silcd/command.c.
3152 * Added channels topic announcements. Affected file is
3153 silcd/packet_receive.c and silcd/server.c.
3155 * Fixed the silc_server_send_notify_topic_set to really destine
3156 the packet to channel. Affected file silcd/packet_send.c.
3158 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
3159 library. Affected file lib/silcclient/client_notify.c.
3161 * Added UMODE announcements. Affected file silcd/server.c.
3163 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3165 * Memory leak fixes in:

3172 lib/silccore/silccommand.c
3173 lib/silccore/silcidcache.c
3178 * ROBOdoc documented the lib/silcske/groups.h file and a
3179 bit changed the interface for better.
3181 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3183 * Update the client entry context in the ID cache after
3184 nick change. Affected file lib/silcclient/command.c.
3185 Fixes the CUMODE command when regaining founder privileges,
3186 and a little WHOIS problem.
3188 * Fixed silc_net_gethostbyname to correctly call the
3189 inet_ntop. Affected file lib/silcutil/silcnet.c.
3191 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3193 * Added IPv6 support checking to the configure.in.pre, added
3194 also --enable-ipv6 option to override the check. Affected
3195 file configure.in.pre.
3197 * The silc_thread_create now calls the start function
3198 directly if threads support is not compiled in. Removes
3199 ugly #ifdef's from generic code. Affected files are
3200 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
3202 * Added silc_net_gethostby[name/addr]_async to asynchronously
3203 resolve. Affected files are lib/silcutil/silcnet.[ch].
3205 * Added support for rendering IPv6 based server, client and
3206 channel IDs. Affected file lib/silcutil/silcutil.c.
3208 * Added support for creating IPv6 based server IDs. Affected
3209 file is silcd/serverid.c.
3211 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3213 * Added silc_net_gethostby[addr/name] into the
3214 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
3215 routines. Added silc_net_is_ip[4/6]. Affected file is
3216 lib/silcutil/unix/silcunixnet.c. All routines that take
3217 address as argument now supports both IPv4 and IPv6 addresses.
3219 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3221 * Fixed LIST command reply sending in server. Affected file
3224 * Server now sends the kicker's client ID in the KICK notify
3225 to the kicked client. Affected file silcd/command.c.
3227 * The client library now parses the kickers client ID and
3228 UI displays it. Affected files lib/silcclient/client_notify.c
3229 and irssi/src/silc/core/silc-channels.c, module-formats.c.
3231 * Made all payload parsing function prototypes consistent.
3232 They all take now const unsigned char * and uint32 pair as
3233 the payload data instead of SilcBuffer. Changes all around
3234 the source tree. Other unsigned char* -> const unsigned char*
3235 changes around the tree as well.
3237 * Optimized SFTP client and server packet sending not to
3238 allocate new buffer for each packet but to recycle the
3239 first allocated buffer. Affected files are
3240 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
3242 * Optimized the SFTP client to use SilcList instead of
3243 SilcDList for requests, because it is faster. Affected file
3244 is lib/silcsftp/sftp_client.c.
3246 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
3247 into lib/silccore/silcid.[ch].
3249 Renamed silcpayload.[ch] into silcargument.[ch].
3251 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3253 * If client entry is deleted with active key agreement
3254 session, abort the session.
3256 The silc_client_abort_key_agreement now calls the completion
3257 callback with new SILC_KEY_AGREEMENT_ABORTED status.
3259 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
3262 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3264 * Don't use __restrict in older GCC's. Affected file is
3265 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
3267 * silc_net_localhost now attempts to reverse lookup the
3268 IP/hostname. Affected file lib/silcutil/silcnet.c.
3270 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
3271 command. It can be used to gain founder privileges at
3272 the same time when joining the channel.
3274 Defined that the SILC_NOTIFY_TYPE_KICKED send the
3275 kicker's client ID as well. Updated protocol specs.
3277 Defined that the server must send SILC_COMMAND_IDENTIFY
3278 command reply with error status to client who sent
3279 private message with invalid client ID.
3281 Updated the protocol specification.
3283 * Added silc_server_send_command_reply to send any
3284 command reply. Affected file silcd/packet_send.[ch].
3286 * Added silc_id_payload_encode_data to encode ID payload
3287 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
3289 * The server now send IDENTIFY command reply with error
3290 status if client ID in private message is invalid. Affected
3291 file silcd/packet_receive.c.
3293 * Save the server key file with server's IP address in
3294 the filename instead of hostname. The affected file is
3295 irssi/src/silc/core/client_ops.c.
3297 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3299 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
3302 * Added libtool support for compiling shared objects in
3303 lib/silcsim. Affected file configure.in.pre and
3304 lib/silcsim/Makefile.am. Original patch by cras.
3306 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3308 * Pid file configuration, and server's config file fixes
3309 patch by toma. Updated CREDITS file.
3311 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3313 * Fixed silc_client_channel_message to not try to decrypt
3314 the message twice if it resolved the destination client
3315 information. This could cause of dropping one channel
3316 message. Affected file lib/silcclient/client_channel.c.
3318 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3320 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3321 lib/silcclient/client.c. This function is used when the SILC
3322 Client is run under some other scheduler, or event loop or
3323 main loop. On GUI applications, for example this may be
3324 desired to used to run the client under the GUI application's
3325 main loop. Typically the GUI application would register an
3326 idle task that calls this function multiple times in a second
3327 to quickly process the SILC specific data.
3329 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3331 * Fixed silc_server_drop() for dropping the supplementary
3332 groups as well, this could cause a security hole on some
3335 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3337 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
3340 * Write PID file after dropping privileges. Added -F option
3341 to run server on foreground. A patch by debolaz.
3342 Affected files silcd/server.c, silcd/silcd.c.
3344 * Fixed MOTD to return the MOTD file server name. Affected
3345 file silcd/command.c.
3347 * Added INFO command reply handling to the Irssi SILC Client.
3348 Affected file irssi/src/silc/core/client_ops.c.
3350 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3352 * Fixed the silc_idcache_list_* routines to really support
3353 the dynamic list. Fixes a crash. Affected file is
3354 lib/silccore/silcidcache.c.
3356 * Fixed the LIST command reply to really call LIST command's
3357 pending callbacks. Affected file silcd/command_reply.c.
3359 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3361 * Update conn->local_entry->nickname after giving NICK
3362 command. Affected file lib/silcclient/command.c.
3364 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3366 * Added the [pid] option to the silcd configuration file
3368 Affected files: serverconfig.[ch] and silcd.c
3370 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3372 * Save fingerprint in WHOIS command reply in server.
3373 Affected file silcd/command_reply.c.
3375 * Fixed NICK commands pending callback registration.
3376 Affected file lib/silcclient/command.c.
3378 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3380 * Use ++server->cmd_ident when sending commands in server,
3381 instead of random number. Affected file silcd/command.c.
3383 * Fixed GETKEY command reply to call actually GETKEY pending
3384 command callbacks. Affected file silcd/command_reply.c.
3386 * A bit stricter check for nicknames. Check for same nickname
3387 in NICK command also. Affected file silcd/command.c.
3389 * Do not call INFO command everytime client ID changes, only
3390 during first connecting. Affected file lib/silcclient/client.c.
3392 * Set the new nickname only after successful command reply for
3393 NICK command is returned by server. Affected file
3394 lib/silcclient/command.c.
3396 * Remove nicknames from nicklist during server_signoff notify.
3397 Should fix /NAMES bit more. The affected file is
3398 irssi/src/silc/core/silc-channels.c.
3400 * Added `fingerprint' field to the SilcIDListData in the
3401 silcd/idlist.h to hold the fingerprint of the client's
3404 Send the fingerprint of the client's public key in WHOIS
3407 Affected files silcd/command.c, and silcd/idlist.[ch].
3409 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3410 create fingerprint from given data.
3412 * Show the fingerprint of the client's public key in WHOIS.
3413 Affected files irssi/src/module-formats.[ch] and
3414 irssi/src/silc/core/client_ops.c.
3416 * Format the multiple same nicknames also during JOIN and
3417 NICK_CHANGE notifys. Affected file is
3418 lib/silcclient/client_notify.c.
3420 * Do not print error on screen for invalid private message
3421 payload since it can come if someone is sending private
3422 messages with wrong key. Affected file
3423 lib/silccore/silcprivate.c.
3425 * Fixed multiple concurrent /PING crash. Affected file
3426 lib/silcclient/command.c.
3428 * Changed the wrong ID encoding. All IP addresses must be
3429 in MSB first order in encoded format. They were encoded
3430 wrong and was in LSB format. Affected files are
3431 silcd/serverid.c, lib/silcutil/silcutil.c.
3433 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3435 * Call the `connect' client operation through the scheduler
3436 in case of error. Affected file lib/silcclient/client.c.
3438 * Call the `failure' client operation even if the error
3439 occurred locally during a protocol. Affected file is
3440 lib/silcclient/protocol.c.
3442 * Added support of sending LIST command to router from normal
3443 server. This way normal server can get list of all channels
3444 in the network too. Fixed the channel list sending in the
3445 server too. Affected files are silcd/command.c, and
3446 silcd/command_reply.[ch].
3448 * Added silc_server_update_channels_by_server and
3449 silc_server_remove_channels_by_server. They are used during
3450 disconnection of primary router and in backup router protocol.
3451 Affected file silcd/server_util.[ch], silcd/server.c and
3452 silcd/server_backup.c.
3454 * Fixed channel adding to global list in IDENTIFY command
3455 reply in server. Affected file silcd/command_reply.c.
3457 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3459 * If the incoming packet type is REKEY or REKEY_DONE process
3460 that packet always synchronously. Fixes yet another MAC
3461 failed error on slow (dialup) connections. Affected file
3462 lib/silcclient/client.c and silcd/server.c.
3464 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3466 * Call check_version SKE callback for initiator too. Affected
3467 file lib/silcske/silcske.c.
3469 * Implemented fix for security hole found in the SKE that was
3470 fixed in the specification few days back; the initiator's
3471 public key is now added to the HASH value computation.
3472 Added backwards support for the old way of doing it too, for
3473 old clients and old servers. Affected file is
3474 lib/silcske/silcske.c.
3476 * Enabled mutual authentication by default in SKE. If initiator
3477 is not providing mutual authentication the responder will
3478 force it. This will provide the proof of posession of the
3479 private key for responder. The affected files are
3480 lib/silcclient/protocol.c and silcd/protocol.c.
3482 * Do not cache anymore the server's public key during SKE.
3483 We do mutual authentication so the proof of posession of
3484 private key is done, and if the server is authenticated in
3485 conn auth protocol with public key we must have the public
3486 key already. Affected file silcd/protocol.c.
3488 * Added new global debug variable: silc_debug_hexdump. If
3489 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3490 file lib/silcutil/silclog.[ch].
3492 * Fixed compilation warning due to char * -> const char *.
3493 Affected files lib/silcutil/silcnet.h, and
3494 lib/silccore/silcauth.[ch].
3496 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3498 * Fixed CMODE command when new channel key was created. If
3499 the creation failed the old key was removed. Next time giving
3500 same command would crash the server since the old key was
3501 freed already. Affected file silcd/command.c.
3503 * Fixed the silc_server_announce_get_channels to not crash
3504 on reconnect. Affected file silcd/server.c.
3506 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3508 * Added silc_log_set_debug_string function to set a regex
3509 string to match for debug output. Only the function names,
3510 or filenames matching the given debug string is actually
3511 printed. This way it is possible to filter out those debug
3512 strings that user is not interested in.
3514 Fixed a bug in silc_string_regexify.
3516 Affected files lib/silcutil/silclog.[ch], and
3517 lib/silcutil/unix/silcunixutil.c.
3519 * Changed the -d options in both server and Irssi SILC client
3520 to take the debug string as argument. Affected files
3521 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3523 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3525 * Added silc_hash_babbleprint to create a Bubble Babble
3526 Encoded fingerprint. The encoding is developed by Antti
3527 Huima (draft-huima-babble-01.txt), and it creates human
3528 readable strings out of binary data. Affected file
3529 lib/silccrypt/silchash.[ch].
3531 * Print the babble print now in addition of fingerprint as well
3532 in Irssi SILC client. Affected files are
3533 irssi/src/fe-common/silc/module-formats.[ch],
3534 irssi/src/fe-common/silc/core/client_ops.c.
3536 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3538 * Fixed a security problem found in SKE. The initiator's
3539 public key too is now added to the HASH hash value creation
3540 which is signed by the responder to create the SIGN value.
3541 This will prevent anyone in the middle to lie to the responder
3542 about the initiator's public key. If this is done now, the
3543 man in the middle will get caught. Updated the protocol
3546 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3548 * Better installation directory handling. Configure module
3549 paths and other paths automatically to example_silc* files
3550 in doc/. A patch by toma.
3552 * Fixed compiler warning from MPI library, and from SILC RNG.
3555 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3556 It can be configured with ./configure. A patch by toma.
3558 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3560 * Find correct make to use in prepare-clean. A patch by
3561 toma. Affected file prepare-clean.
3563 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3565 * Added irssi variables use_auto_addr, auto_bind_ip,
3566 auto_bind_port and auto_public_ip.
3568 * Changed the interface for silc_client_send_key_agreement
3569 in lib/silcclient/silcapi.h
3573 irssi/src/silc/core/silc-core.c
3575 lib/silcclient/silcapi.h
3576 irssi/src/silc/core/silc-channels.c
3577 lib/silcclient/client_keyagr.c
3580 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3582 * Added silc_pkcs_public_key_compare to compare two
3583 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3585 * Check that the client who set the founder mode on the
3586 channel is the same client that is giving the founder
3587 mode to itself. It is done by comparing the saved public
3588 key (it is saved even in the authentication is passphrase).
3589 Affected file silcd/command.c.
3591 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3593 * Do not process packet for disconnected socket connection.
3594 Affected file lib/silccore/silcpacket.c.
3596 * Process the DISCONNECT packet through scheduler in the
3597 client library. Affected file lib/silcclient/client.c.
3599 * Fixed the silc_client_packet_parse to not to increase
3600 the packet sequence number if the conn->sock and the
3601 current socket connection is not same. This can happen
3602 for example during key agreement when the conn includes
3603 multiple socket connections (listeners). Affected file
3604 lib/silcclient/client.c.
3606 * The sender of the file transfer request now provides also
3607 the pointer (listener) for the key exchange protocol. If
3608 the listener cannot be created then it sends empty key
3609 agreement and lets the receiver provide the listener.
3611 Added `local_ip' and `local_port' arguments to the
3612 silc_client_file_send. If they are provided they are used,
3613 if not then it will attempt to find local IP address, if
3614 not found or bind fails then the remote client will provide
3617 Affected files are lib/silcclient/client_ftp.c and
3618 lib/silcclient/silcapi.h.
3620 * Extended the FILE SEND command to support defining the
3621 local IP and port for key exchange listener. They are
3622 optional. Affected file irssi/src/silc/core/silc-servers.c.
3624 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3626 * Defined to WHOIS command reply the sending of fingerprint
3627 of the client's public key (if the proof of posession of the
3628 corresponding private key is verified by the server).
3629 Updated to the protocol specification.
3631 * Added support of receiving the client's public key's
3632 fingerprint in command reply in client library. Affected
3633 file is lib/silcclient/command_reply.c, and
3634 lib/silcclient/idlist.[ch].
3636 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3638 * Do not send over 128 chars long nickname to the server
3639 in NICK command. Affected file lib/silcclient/command.c.
3641 * Do not send over 256 chars long channel names to the server
3642 in JOIN command. Affected file lib/silcclient/command.c.
3644 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3646 * Assure that silc_server_close_connection cannot be called
3647 twice for same socket context. Affected file is
3650 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3652 * Send error message to application if opening file for
3653 writing during file transfer fails. Affected file is
3654 lib/silcclient/client_ftp.c.
3656 Remove all file transfer sessions for a client that we're
3657 removing from ID cache.
3659 Affected file is lib/silcclient/client_ftp.c.
3661 * Fixed silc_net_addr2bin to return correct address. Affected
3662 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.

3689 client library. Affected file lib/silcclient/client_prvmsg.c.
3691 * Do not actually remove the client directly from ID cache
3692 during SERVER_SIGNOFF, but invalidate it. This way we
3693 preserve the WHOWAS info for the client. Affected file
3694 silcd/server_util.c.
3696 * Fixed SERVER_SIGNOFF notify handling in the server. The
3697 server is now able to process incoming SERVER_SIGNOFF notify
3698 for a server that it doesn't even know about. It will remove
3699 the clients provided in the notify. Affected file
3700 silcd/packet_receive.c.
3702 * Check for partial packet in data queue after every packet that
3703 was found from the queue. Return and wait for more data if
3704 there is partial data in queue. Affected file is
3705 lib/silccore/silcpacket.c.
3707 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

3715 * Check that newsize in silc_buffer_realloc is larger than
3716 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3718 * Added better monitor of file transfers. It now monitors
3719 key agreement protocol during the file transfer too. Added
3720 error reporting too. Affected files
3721 irssi/src/silc/core/silc-servers.c,
3722 irssi/src/fe-common/silc/module-formats.[ch].
3724 * Wrote a help file for FILE command.
3726 * Added silc_rng_global_get_byte_fast to get not-so-secure
3727 random data as fast as possible. Random data is read from
3728 /dev/urandom if available and from the SILC RNG if not
3729 available. It is used in padding generation. Affected file
3730 lib/silccrypt/silcrng.[ch].
3732 * All packets in client library are now processed synchronously.
3733 Optimized packet processing a lot. Affected file
3734 lib/silcclient/client.c.
3736 * All server connection packets are processing synchronously
3737 now in server, to optimize packet processing. Affected file
3740 * Include files are installed now only in Toolkit distribution
3741 if make install is given. Affected files: all Makefile.am's.
3743 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3745 * Assure that silc_client_notify_by_server_resolve does not
3746 resolve the client information multiple times. If it cannot
3747 be found by the first it cannot be found at all. Affected
3748 file lib/silcclient/client_notify.c.
3750 * Fixed WHOWAS command reply calling. Affected file
3751 lib/silcclient/command_reply.c.
3753 * Removed all references to silc_idlist_get_client from the
3754 Irssi SILC client since that call is internal call used by
3755 the library. The Irssi SILC client will use now client
3756 retrieval functions found in silcapi.h.
3758 * Fixed a bug in resolving nickname info before sending
3759 private message. It used freed memory. Affected file
3760 irssi/src/silc/core/silc-servers.c.
3762 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3764 * Assure my_channels statistics cannot go negative in server.
3765 Affected files silcd/server.c, silcd/server_util.c.
3767 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3781 * Added silc_net_localip to return local host's IP address.
3782 Affected file lib/silcutil/silcnet.[ch].
3784 * If key exchange or rekey protocol is active for a connection
3785 parse all packets syncronously since there might be packets
3786 in packet queue that we are not able to process without first
3787 processing packets before them. Affected file silcd/server,
3788 lib/silcclient/client.c.
3790 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3791 whether library should continue processing the packet.
3792 Affected file lib/silccore/silcpacket.h.

3823 lib/silcutil/silcutil.[ch].
3825 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3827 * Resolve the client info when received private message or
3828 channel message for a client which nickname we don't know.
3829 Affected files lib/silcclient/client_prvmsg.c and
3830 lib/silcclient/client_channel.c.

3833 file irssi/src/silc/core/silc-channels.c.
3835 * Added SilcClientStatus field to the SilcClientEntry in the
3836 lib/silcclient/idlist.h.
3838 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3839 is incomplete and is being resolved, it won't be resolved
3842 Make sure also that USERS command reply does not resolve
3843 twice information. Affected file is
3844 lib/silcclient/command_reply.c.
3846 Make sure that silc_client_get_clients_by_list does not
3847 resolve twice same information.
3849 * Check for valid client->id in the silc_server_free_client_data.
3850 Affected file silcd/server.c.
3852 * Fixed /GETKEY nick@server not to crash if the server entry
3853 is not found. Affected file lib/silcclient/command.c.
3855 * Fixed the silc_server_check_cmode_rights to check the
3856 requested modes correctly. Affected file silcd/command.c.

3861 Affected file silcd/command.c.
3863 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3865 * Call the silc_server_udpate_servers_by_server in the
3866 primary router that comes back online in the backup resuming
3867 protocol. Otherwise it routes packets wrong. Affected file
3868 silcd/server_util.[ch], silcd/server_backup.c.
3870 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3872 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3873 lib/silcutil/silcbuffmt.[ch].
3875 * Redefined the SILC packet header to include the padding
3876 length. Affected file lib/silccore/silcpacket.[ch].
3878 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3879 length for maximum padding up to 128 bytes). Affected
3880 file lib/silccore/silcpacket.h.
3882 * Removed all backwards support for old 0.5.x MAC thingies.
3883 The SILC packet header change makes it impossible to be
3884 backwards compatible.
3886 * Send the ENDING packet with timeout in the backup resuming
3887 protocol. This is to assure that all routers has connected
3888 to the primary router. Affected file silcd/server_backup.c.
3890 * Changed the RNG to take the first IV from random data. It
3891 used to take it from zero actually. Changed the RNG also
3892 to use /dev/urandom during session. /dev/random is used
3893 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3895 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3897 * Changed the SILC packet header to have the first two bytes
3898 (the packet length) encrypted. Affected files aroung the
3899 code tree, lib/silccore/silcpacket.[ch]. Removed the
3900 SilcPacketCheckDecrypt callback. It is not needed anymore
3901 since the silc_packet_receive_process will determine now
3902 whether the packet is normal or special.
3904 * Implemented the unidirectional MAC keys. Affected files
3905 lib/silcske/silcske.c, silcd/protocol.c and
3906 lib/silcclient/protocol.c.
3908 * Implemented the packet sequence number to the MAC computation.
3909 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3910 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3911 lib/silcclient/protocol.c.
3913 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3915 * Allow backup router to announce servers. All servers
3916 announced by backup router are added to the global list
3917 automatically. Update hte server's socket to our primary
3918 router also when backup router announces a server.
3919 Affected file silcd/packet_receive.c.
3921 * Do not update the client->router in the function
3922 silc_server_udpate_clients_by_server if the client is on
3923 global list. We might fail to find any specific server
3924 for locally connected clients and local cell clients. They
3925 should still use the `from' and not `to' as client->router.
3926 This fixes backup router resuming protocol. Affected file
3927 silcd/server_util.c.
3929 * Decrease channel statistics count only if the channel
3930 deletion worked. Affected files are silcd/server.c and
3931 silcd/server_util.c.
3933 * Added silc_server_update_servers_by_server to update origin
3934 of all server entries. Used during backup router protocol.
3935 Affected files silcd/server_util.[ch], silcd/server.c. and
3936 silcd/backup_router.c.
3938 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3939 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3940 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3941 lib/silccrypt/silchmac.c.
3943 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3945 * Assure that router cannot reroute the same channel message
3946 to the sender. Affected file silcd/packet_receive.c.
3948 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3950 * Made better checks that the channel message is not sent
3951 to the router it came from. Affected file is
3952 silcd/packet_send.c. Fixed memory leak too.
3954 * Announce informations for incoming router connection, but
3955 only after checking if it is replaced by backup router.
3956 Affected file silcd/packet_receive.c.
3958 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3960 * Fixed the backup resuming protocol to work in multiple
3961 router environment. Affected file silcd/server_backup.c.
3963 * Route packet only to one router in the function
3964 silc_server_packet_send_to_channel. Affected file is
3965 silcd/packet_send.c.
3967 * Fixed silc_server_send_notify_dest to set the broadcast
3968 flag. Fixed the silc_server_send_notify_topic to actually
3969 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3970 Affected file silcd/packet_send.c.
3972 * Changed the SFTP Filesystem interface. Changed the
3973 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3974 the filesystem operation function. The SilcSFTPFilesystem
3975 is now a context that is allocated by all filesystem allocation
3976 functions and it already includes the operations structure
3977 and filesystem specific context. It is given as argument
3978 now to the silc_sftp_server_start. This made the interface
3979 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3980 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3982 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3984 * Changed the backup router adding and getting interfaces
3985 in the server. The router that will be replaced by the
3986 specified backup router is now sent as argument. Affected
3987 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3990 * Added silc_net_addr2bin_ne to return the binary form of
3991 the IP address in network byte order. Affected files
3992 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3994 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3996 * Check for existing server ID in silc_server_new_server
3997 and in silc_server_connect_to_router_final and remove the
3998 old entry if it exists. Affected file silcd/packet_receive.c,
4001 * Send the channel message always to only one router, either
4002 in upstream or downstream. Affected file is
4003 silcd/packet_send.c.
4005 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4007 * Wrote the definition of the backup resuming protocol to the
4008 protocol specification.
4010 * Removed one redundant channel key generation from normal
4011 server during joining procedure. Removed one redundant
4012 channel key sending from server to router during joining
4013 procedure. Affected file silcd/command.c.
4015 * Made minor bugfixes to the backup router resuming protocol.
4016 Affected file silcd/server_backup.c, server.c.
4018 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4020 * Added --disable-asm configuration option. Affected files
4021 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
4024 * Implemented the backup resuming protocol that is used to
4025 resume the primary router position in the cell after the
4026 primary router comes back online. Affected files
4027 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
4028 and silcd/server_util.[ch].
4030 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4032 * Sleep two (2) seconds after sending QUIT command to server.
4033 Affected file lib/silcclient/command.c.
4035 * Assure that if outgoing data buffer is pending do not force
4036 send any data. Affected file silcd/packet_send.c.
4038 * Assure that if outgoing data buffer is pending do not force
4039 send any data. Affected file lib/silcclient/client.c.
4041 * Implemented the backup router support when the primary router
4042 goes down. The servers and routers can now use the backup
4043 router as new primary router without loosing connectivity.
4045 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4047 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
4048 in the server to indicate disabled entry. All data read
4049 from the connection will be ignored and no data is sent
4050 for entry that is disabled. Affected files are
4051 silcd/idlist.h, silcd/server.c.
4053 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4055 * Created SFTP client and server test programs in the
4056 lib/silcsftp/tests directory.
4058 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4060 * Implemented memory filesystem (virtual filesystem) for
4061 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
4064 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4066 * Implemented the SFTP (SSH File Transfer Protocol) to the
4067 lib/silcsftp. It includes SFTP client and SFTP server
4070 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4072 * Moved lib/silccore/silcprotocol.[ch] to the
4073 lib/silcutil library.
4075 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
4076 take variable argument list pointer as argument. Affected
4077 file lib/silcutil/silcbuffmt.[ch].
4079 * Added silc_buffer_set function that is used to set data
4080 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
4081 Affected file lib/silcutil/silcbuffer.h.
4083 * Changed various routines in the core library to use the new
4084 silc_buffer_set instead of allocating new buffer only for
4087 * Added 64-bit value formatting and unformatting support to the
4088 silc_buffer_[un]format routines. Affected file is
4089 lib/silcutil/silcbuffmt.[ch].
4091 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
4092 to includes/bitmove.h.
4094 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4096 * Fixed channel user mode saving in client library. Affected
4097 file lib/silcclient/command[_reply].c.
4099 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4101 * Defined the file transfer to the SILC Protocol. Added
4102 new packet type SILC_PACKET_FTP and defined File Transfer
4103 Payload. The mandatory file transfer protocol is SFTP
4104 (SSH File Transfer Protocol). Affected file in addition
4105 of the internet draft is lib/silccore/silcpacket.h.
4107 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
4108 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
4109 is used as part of backup router protocol when the primary
4110 router of the cell is back online and wishes to resume
4111 the position as primary router.
4113 * Redefined the MAC generation keys in the protocol. The
4114 same key is not used anymore in both direction. Both
4115 direction will now use different keys for sending and
4116 receiving. This fixes a potential security flaw. This
4117 change causes incompatibilities in the protocol.
4119 * Redefined also the MAC computation from the packet.
4120 An packet sequence number is now added to the MAC
4121 computation. This prevents possible replay attacks against
4122 the protocol. This change too causes incompatibilities
4125 Added `sequence' field to the SilcPacketContext to hold
4126 the current sequence number for the packet.
4128 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4130 * Added `created' field to the SilcIDListData in the file
4131 silcd/idlist.h to indicate the time when the entry was
4134 * Added `created' field to the SilcChannelEntry too. Affected
4135 file silcd/idlist.h.
4137 * Added `creation_time' aguments to all the announcement functions
4138 in the server. If it is provided then only the entries that
4139 was created after the provided time frame are actually
4140 announced. Affected file silcd/server.[ch].
4142 * The protocol says that the Channel ID's IP address must be
4143 based on the router's IP address. Added check for this in
4144 the silc_server_new_channel when processing incoming New Channel
4145 Payload. Affected file silcd/packet_receive.c.
4147 * Print out the correct version with --version in SILC client.
4148 Affected file irssi/src/silc/core/silc-core.c.
4150 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4152 * Fixed WHOWAS command to check for completnes of the client
4153 entry always, not just when the command is coming from client.
4154 Affected file silcd/command.c.
4156 * Added new function silc_server_packet_queue_purge to purge the
4157 outgoing data queue to the network. After the function returns
4158 it is guaranteed that the outgoing packet queue is empty.
4159 Affected file silcd/packet_send.[ch].
4161 * Purge the outgoing packet queue in the rekey protocol's final
4162 callback to assure that all rekey packets go to the network
4163 before quitting the protocol. Affected file silcd/server.c.
4165 * Added silc_client_packet_queue_parse as similar function as
4166 in server to the client library. The affected file is
4167 lib/silcclient/client.c.
4169 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4171 * Splitted silcd/server.c and created silcd/server_util.[ch]
4172 for utility functions.
4174 * Added new socket flag SILC_SF_DISABLED to indicate that the
4175 connection is open but nothing can be sent to or received from
4176 the connection. Affected file lib/silcutil/silsockconn.[ch].
4177 The checking for disabled socket is checked in the low level
4178 silc_socket_write and silc_socket_read functions.
4180 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4182 * Allow only nicknames and channel names that fits into the
4183 7-bit unsigned char ASCII set. Affected file silcd/command.c.
4185 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4187 * When processing JOIN command reply in server check that if
4188 the channel exists in our global list we'll move it the local
4189 list. Affected file silcd/command_reply.c.
4191 * Fixed the check whether client is joined on the channel already
4192 in JOIN command. Affected file lib/silcclient/command.c.
4194 * Fixed the JOIN command reply to check whether the channel
4195 already exists. Affected file lib/silcclient/command_reply.c.
4197 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4199 * Added silc_ske_status_string to map the SKE error numbers
4200 to readable strings. The affected files are
4201 lib/silcske/silcske[_status].[ch].
4203 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4205 * Do not show the private channels on the WHOIS channel list
4206 as it is not allowed by the protocol. The affected file is
4209 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4211 * Assure that the packet length digged from the actual packet
4212 is something sensible in the silc_packet_decrypt_rest_special
4213 in lib/silccrypt/silcpacket.c.
4215 * Free and NULL the allocated pointer in silc_hmac_alloc if
4216 the HMAC allocation fails. The affected file is
4217 lib/silccrypt/silchmac.c.
4219 * Print the selected security properties to the log files in
4220 the server. Affected file silcd/protocol.c.
4222 * Add SKE's reference counter even if calling the completion
4223 callback manually. Otherwise it goes negative, although it
4224 does not cause any problems. The affected file is
4225 lib/silcske/silcske.c.
4227 * Remove the client entry with short timeout after giving the
4228 KILL command. Affected file lib/silcclient/command.c.
4230 * Fixed to send error reply in WHOIS and IDENTIFY commands in
4231 case all found clients are already disconnected (WHOWAS would
4232 found them) in the server. Affected file silcd/command.c.
4234 * Update the last_receive (time of last data received) to be
4235 updated only when received private or channel message so that
4236 the idle time showed in WHOIS makes more sense.
4238 * Added boolean field `valid' in to the SilcClientEntry in the
4239 client library to indicate whether the entry is valid or not.
4240 This fixes the nickname change bug on channel when changing
4241 the nickname to be same than the old (like nick to Nick) the
4242 nickname formatter doesn't set the new nick anymore to Nick@host.
4243 Affected file lib/silcclient/idlist.[ch].
4245 * Now actually fixed the nickname changing on disconnection.
4246 Added new function silc_change_nick to the Irssi SILC Client.
4247 Affected file irssi/src/silc/core/client_ops.c,
4248 irssi/src/silc/core/silc-nicklist.[ch].
4250 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4252 * Check that the public key exists in the GETKEY command before
4253 trying to encode it. Affected file silcd/command.c.
4255 * Print some notifications on received public keys with GETKEY
4256 command in the Irssi SILC Client. Affected files are
4257 irssi/src/fe-common/silc/module-formats.[ch],
4258 irssi/src/silc/core/client_ops.c.
4260 * Use IDENTIFY command to resolve the server information in the
4261 GETKEY command instead of INFO command. Affected file
4262 lib/silcclient/command.c.
4264 * All command reply functions in the client library now calls
4265 the pending command reply callbacks even if an error has
4266 occurred. The server has done this a long time and now it was
4267 time to move the client library to this as well. Now all
4268 errors can be delivered back to the pending command reply
4269 callbacks if necessary. Affected files are
4270 lib/silcclient/command[_reply].[ch].
4272 * Change the nickname on disconnection back to the username
4273 because in reconnect the server will enforce it to it anyway.
4274 Affected file irssi/src/silc/core/silc-servers.c.
4276 * Fixed a config file parsing bug in the Irssi SILC client.
4277 Affected file irssi/src/silc/core/clientconfig.c.
4279 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4281 * When printing the channel mode on JOIN, verify that the
4282 channel key and channel's HMAC are valid. Affected file
4283 irssi/src/silc/core/client_ops.c.
4285 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4287 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
4288 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
4289 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
4291 * Removed channel key rekey task deleting from the function
4292 silc_server_save_channel_key. Affected file silcd/server.c.
4293 Added explicit timeout task context instead that is used to
4294 delete the task if we are registering a new task before the
4295 new task has elapsed.
4297 * When channel key rekey occurs the client library now saves
4298 the old channel key for a short period of time (10 seconds) and
4299 is able to use it in case some is still sending channel
4300 messages encrypted with the old key after the rekey. Affected
4301 file lib/silcclient/[idlist.h|client_channel.c].
4303 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4305 * Added check to the silc_server_new_id_real to not accept
4306 new ID if it is the sender's own ID. Affected file is
4307 silcd/packet_receive.c.
4309 * Assure that we do not announce ourself or the one we've
4310 sending our announcements when we're router and are announcing
4311 servers to our primary router. Affected file silcd/server.c.
4313 * Fixed silc_server_command_identify_check_client to assemble
4314 correct WHOIS packet. It send corrupted WHOIS packet and
4315 caused problem with router to router connections. Affected
4316 file silcd/command.c.
4318 Fixed also silc_server_command_whois_check the same way
4319 as for the IDENTIFY command.
4321 * Added new SilcIDListStatus to the server in the SilcIDListData
4322 structure. The status now includes the current status of
4323 the entry (like registered, resolved etc.). Affected file
4324 silcd/idlist.[ch]. Defined a bunch of different status types
4325 as well. This replaced the old boolean registered field as well.
4327 Added resolve_cmd_ident field to the SilcClientEntry structure
4328 too so that if the entry is for example being resolved so
4329 another command may attach to the same pending command reply
4330 without requiring to resolve the same entry again. This concept
4331 should optimize the WHOIS and the IDENTIFY resolving under
4332 heavy load by taking away unnecessary resolving for entries
4333 that are being resolved already.
4335 Added support for adding multiple pending commands for one
4336 command idenfier. Affected file silcd/command[_reply].[ch].
4338 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4339 before deleting the data. Otherwise the hash table will have
4340 freed data in comparison functions. Affected file is
4341 silcd/command_reply.c.
4343 * Fixed silc_idlist_replace_client_id to add the new entry to
4344 the cache with NULL nickname. Otherwise there will be invalid
4345 memory as the nickname after the nickname is freed. Affected
4346 file silcd/packet_receive.c.
4348 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4349 saved into wrong slots because the previous number of entries
4350 was not taken into account. Affected file silcd/idlist.c.
4351 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4353 * If we are router and we receive JOIN notify to a channel that
4354 does not have any users then notified client is marked as the
4355 channel founder, as it is it. The affected file is
4356 silcd/packet_receive.c
4358 * Added to the extended hash table API's table_del_*ext functions
4359 the destructor as argument too, so that the caller can decide
4360 which destructor to use or whether to use destructor at all.
4361 Affected file lib/silcutil/silchashtable.[ch].
4363 * Fixed ID Cache purging. It actually deleted the entries from
4364 the hash table after the data was freed. The hash table ended
4365 up comparing freed memory. The affected file is
4366 lib/silccore/silcidcache.c.
4368 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4370 * Fixed Irssi SILC client's KILL command's HELP syntax.
4372 * The USERS command now resolves the detailed user information
4373 if the userinfo field is missing. Affected file is
4374 lib/silcclient/command_reply.c.
4376 * Do not print error in silc_file_read if the read file does
4377 not exist. Just silently return NULL. Affected file is
4378 lib/silcutil/silcutil.c.
4380 * Fixed the silc_log_output to not wine about NULL filename
4381 and to not create some bogus " " filename. Affected file is
4382 lib/silcutil/silclog.c.
4384 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4386 * Fixed various printing bugs on the user interface in the
4387 Irssi SILC Client. Minor changes that were forgotten from
4390 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4392 * Fixed the configure.in.pre and the compilation and distribution
4393 environment to support the new autoconf 2.52. That version is
4394 now required to compile the CVS trunk.
4396 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4398 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4399 to generally parse user@fqdn format strings. Affected file
4400 lib/silcutil/silcutil.c.
4402 * Added nickname_format and nickname_force_format fields to the
4403 SilcClientParams structure. The first one defines the format
4404 for the nicknames that the library will enforce if the receives
4405 multiple same nicknames. The second one is boolean value and
4406 can be used to force the library to always enforce the format
4407 to the nicknames regardles whether there are multiple nicknames
4408 or not. This configurable formatting was employed to flexibly
4409 support accessing multiple nicknames from the user interface.
4410 The userinterface can now set the nicknames to what ever format
4411 they prefer. Affected file lib/silcclient/silcapi.h.
4413 Added function silc_client_nickname_format to the file
4414 lib/silcclient/idlist.c. It performs the nickname formatting.
4416 Added new field `hostname´ to the SilcClientEntry context.
4417 It holds the hostname of the client. Affected file is
4418 lib/silcclient/idlist.h.
4420 * Irssi SILC Client sets the nicknames in nick@hostn format.
4421 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4422 irssi/src/silc/core/silc-core.c.
4424 The WHOIS printing now also shows both the real nickname and
4425 the formatted nickname so that user knows how to access the
4426 user if there are multiple same nicknames cached. Affected
4427 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4428 printing formatting too to take the hostname now as a separate
4429 argument. The Affected file is
4430 irssi/src/fe-common/silc/modules-formats.[ch].
4432 * Changed the silc_client_get_clients_local to accept the formatted
4433 nickname as argument. It accepts the real nickname too but the
4434 formatted nickname can be used to find the true entry from
4435 multiple entries. Affected file lib/silcclient/silcapi.h and
4436 lib/silcclient/idlist.c.
4438 * Added nickname_format_parse field to the SilcClientParams.
4439 It is a callback function provided by the application to parse
4440 the nickname out of the formatted nickname string. The library
4441 calls it to get the nickname from the formatted string. Since
4442 the application generally knows better the format of the nickname
4443 string it parses it instead of the library, even though library
4444 encodes the formatted string. If the callback function is not
4445 provided then the library will use the string as is. The
4446 affected file is lib/silcclient/silcapi.h.
4448 * All the nickname strings passed to the client library in
4449 commands are now expected to be formatted nickname strings.
4450 If the command does not support the formatted nickname string
4451 it will assume that the sent string is the actual nickname.
4452 Affected file lib/silcclient/command.c.
4454 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4456 * Added public key authentication support to OPER and SILCOPER
4457 commands in the client library. Affected file is
4458 lib/silcclient/command.c.
4460 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4462 * Changed the get_auth_methdod client operation to be asynchronous.
4463 It can be async if the application resolves the authentication
4464 method from the server during the negotiation. Added new
4465 SilcGetAuthMeth completion callback that the application will
4466 call after resolving the authentication method.
4468 Added function silc_client_request_authentication_method that
4469 the application can use to resolve the authentication method
4470 from the server. Added also SilcConnectionAuthRequest callback
4471 that the library will call after the server has replied. The
4472 application can call this function if it does not know the
4473 current authentication method.
4475 Affected files are lib/silcclient/client.c and
4476 lib/silcclient/silcapi.h.
4478 * The Irssi SILC client now automatically resolves the authentication
4479 method incase any configuration information is not present (and
4480 currently there never is). The affected file is
4481 irssi/src/silc/core/client_ops.c.
4483 * Fixed public key authentication from the client library.
4484 Affected file lib/silcclient/protocol.c. Changed also the
4485 protocol specification about the public key authentication in
4486 the connection authentication protocol. The actual data to be
4487 signed is now computed with a hash function before signing.
4489 * Fixed the public key authentication from the server as well.
4490 Affected file silcd/protocol.c.
4492 * Removed the mlock()'s from the memory allocation routines.
4493 Affected file lib/silcutil/silcmemory.c. The ./configure does
4494 not check anymore for the mlock(). Affected file is
4497 * Fixed USERS command in server to allow the execution of the
4498 command for private and secret channels if the client sending
4499 the command is on the channel. Affected file silcd/command.c.
4501 * Fixed silc_client_get_clients_local to return the clients
4502 count correctly. It could return wrong value. Affected file
4503 lib/silcclient/idlist.c.
4505 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4507 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4508 types. The assembler optimizations seemed not to like 64-bit
4509 data types. The assmebler optimizations thus are now enabled
4510 also for BSD systems as opposed to only enable them for Linux.
4512 * Do not check for threads at all on BSD systems. Affected
4513 file configure.in.pre.
4515 * Removed -n and -h options from the Irssi SILC Client since
4516 they are not used in silc.
4518 * Fixed the prime generation to assure that the first digit
4519 of the generated random number is not zero since our conversion
4520 routines does not like number strings that starts with zero
4521 digit. If zero digit is seen the random number is regenerated.
4522 This caused some corrupted RSA keys when the zero first digit
4523 was met. Affected file lib/silcmath/silcprimegen.c.
4525 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4527 * Fixed WIN32 configuration in the ./configure script.
4528 Fixed to include xti.h on environments that has it.
4529 Patches by Carsten Ilchmann and andrew.
4531 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4533 * Changed the silc_id_create_client_id to be collision
4534 resistant. It is now assured that there cannot be created
4535 two same client ID's. I suspect that some weird bugs in
4536 the server were actually caused by duplicate Client IDs.
4537 Affected file silcd/serverid.[ch]. A router receiving
4538 new ID now also assures and informs the sending server
4539 if the ID caused collision.
4541 * Changed the silc_id_create_channel_id to also assure that
4542 there are no collisions.
4544 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4546 * Statement about ignoring the Mutual Authentication flag when
4547 performing rekey with PFS was a bit misleading. It is ignored
4548 if it was set in the initial negotiation, it cannot be even
4549 set in the rekey. Fixed in the ke-auth draft. Started the
4550 new versions of the protocol drafts in the doc/.
4552 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4554 * Fixed a bug in silc_client_command_identify_save when saving
4555 new channel information. The channel name was no duplicated
4556 and caused crash on exit. Affected file is
4557 lib/silcclient/command_reply.c.
4559 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4561 * Fixed the getkey command handling in the server. Send just
4562 empty OK reply to the sender if the key could not be fetched
4563 (but everything else was ok, like the key just was not available).
4564 Changed the public key parameter to optional in the protocol
4565 specs so that empty OK reply can be sent. Affected file
4568 Added a message to Irssi SILC client to tell to user if the
4569 server did not return a public key.
4571 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4573 * Fixed a channel key regeneration bug. It registered new
4574 timeout tasks exponentially until all system resources were
4575 used. Affected file silcd/server.c.
4577 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4579 * Added the SILC Document generator to the scripts/silcdoc.
4580 It can be used to generate the Toolkit Reference Manual out
4581 of the source tree. Internally it will also use the RoboDoc
4582 generator now imported in util/robodoc.
4584 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4586 * Added couple of return's in rekey protocol if error orccurred
4587 during the protocol. The execution must be terminated.
4588 Affected file silcd/protocol.c. Also, terminate the protocol
4589 always with timeout.
4591 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4593 * The client's Client ID was created initally from the wrong
4594 nickname (it could have been in format nick@host) in the
4595 silc_server_new_client. Affected file silcd/packet_receive.c
4597 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4599 * Added some SILC_LOG_ERROR's to various error conditions
4600 if client could not be added to ID cache. Affected files
4601 silcd/packet_receive.c and silcd/server.c.
4603 * When client's sock->user_data is freed, NULL also the
4604 client->router and client->connection pointers. Added check
4605 for these pointers being NULL to various places around the
4606 code. Affected file silcd/server.c.
4608 * Added client->data.registered == TRUE checks to various
4609 places around the code to assure that unregistered client's
4610 are not handled when it is not allowed. Affected file
4613 * Added `bool registered' fields to all
4614 silc_idlist_[server|client]_get_* routines to indicate whether
4615 the fetched client needs to be registered or not. Affected
4616 file silcd/idlist.[ch].
4618 * Add your own entry as registered to the ID cache in the
4619 server. Affected file server.c.
4621 * Fixed a bug in silc_server_new_server. The SilcServer was
4622 set as the new server's context instead of SilcServerEntry.
4623 This naturally caused some weird bugs.
4625 * Added "updated" field the SilcChannelEntry which indicates
4626 the time since the channel entry was last accessed. This
4627 can be used to determine whether it is necessary to
4628 announce the channel after backup resuming protocol.
4629 Affected files silcd/idlist.[ch].
4631 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4633 * Do not delete the channel rekey task when adding it
4634 for in silc_server_create_channel_key.
4636 * Changed the silc_server_create_channel_key to return
4637 TRUE or FALSE to indicate the success of the channel key
4640 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4642 * Fixed MSVC++ project files and added missing files to
4643 Makefiles under win32/.
4645 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4647 * Do not add TCP_NODELAY flag if the operating system
4648 does not have it defined. Affected files are
4649 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4651 * Fixed buffer overflow from Irssi SILC Client. Affected
4652 file irssi/src/fe-common/core/themes.c.
4654 * Fixed double free in client library in the file
4655 lib/silcclient/client.c when disconnecting from server.
4657 * Applied double free patch from cras to Irssi SILC client.
4658 Affected files irssi/src/core/[modules/expandos].c
4660 * Fixed the disconnection handling to Irssi SILC Client.
4661 The application must call silc_client_close_connection
4662 in ops->connect client operation in case of failure of
4663 the connection. Affected file is
4664 irssi/src/silc/core/client_ops.c.
4666 * Do not set sock->protocol to NULL in the function
4667 silc_client_close_connection after executing the protocol's
4668 final callback since the sock might not be valid anymore.
4669 Affected file lib/silcclient/client.c.
4671 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4673 * Do not enable SILC_THREADS if the linking with libpthread
4674 did not happen. Affected file configure.in.pre.
4676 * Added notion to protocol specification that server must
4677 verify the sent authentication payload with CMODE when
4678 setting the channel founder key. Implemented it to the
4679 server. Affected file silcd/command.c.
4681 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4683 * Added _EXTRA_DIST SILC distribution variable to the
4684 distributions file. It is used to conditionally add extra
4685 files or directories to the specific distribution. Affected
4686 files ./prepare, Makefile.am.pre and distributions.
4688 Removed the `_' from the start of the distribution names.
4691 * Added README.WIN32 for instructions to compile the Toolkit
4694 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4696 * Fixed a double free in disconnection in the server. Affected
4697 file is silcd/server.c.
4699 * Fixed the lib/silcske/groups.c to work now also with GMP
4700 MP library. The string conversion did not work when using
4701 specific base and the base is indicated in the string as well.
4703 * Created win32/ directory which now includes MSVC++ specific
4704 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4705 It will appear only in the toolkit distribution
4707 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4709 * Changed the key material distribution function in case when
4710 the hash output is too short. The data is now concatenated
4711 a bit differently than it used to. Made the change to the
4712 SKE protocol specification.
4714 * Added better GMP detection to configure.in.pre. A patch
4717 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4719 * Fixed a minor bug in SKE that might cause some problem on
4720 some platforms. Affected file lib/silcske/silcske.c.
4722 * Added the cookie checking for initiator in the SKE. It checks
4723 that the responder returns the sent cookie unmodified. The
4724 affected file is lib/silcske/silcske.c. Added new SKE
4725 error type INVALID_COOKIE that can be sent during the
4726 negotiation. Fixed some memory leaks as well.
4728 * Added the "invalid cookie" error message to Irssi SILC client's
4731 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4733 * Added `task_max' field to the SilcClientParams to indicate
4734 the maximum tasks the scheduler can handle. If set to zero,
4735 default values are used. Affected file lib/silcclient/silcapi.h.
4737 * Fixed memory leaks in silc_client_close_connection. Affected
4738 file lib/silcclient/client.c.
4740 * Added silc_client_del_client_entry to client library to free
4741 all memory of given client entry. Affected file is
4742 lib/silcclient/idlist.[ch].
4744 * Added new functions silc_client_del_channel and
4745 silc_client_del_server to delete channel and server entries.
4746 Affected file lib/silcclient/[silcapi.h/idlist.c].
4748 * Removed silc_client_del_client_by_id from silcapi.h.
4750 * Fixed the INFO command to return the server's own info
4751 correctly when querying by Server ID. Affected file is
4754 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4756 * Removed the non-blocking settings in WIN32 code in the
4757 silc_sock_[read/write] and added SleepEx instead. Affected
4758 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4759 of input data is now checked with FIONREAD and ioctlsocket.
4761 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4763 * Call silc_schedule_task_del_by_context in the
4764 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4765 Affected file lib/silccore/silcprotocol.c.
4767 * Call silc_protocol_cancel for active protocols in the
4768 silc_server_close_connection if the funtion
4769 silc_server_free_sock_user_data has not been called.
4770 Affected file silcd/server.c.
4772 * Generic tasks cannot be deleted using the del_by_fd
4773 task deleting function since generic tasks does not match
4774 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4776 * Added a notion to SILCOPER help file that the SILCOPER works
4777 only on router server, not on normal server.
4779 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4781 * Added for WIN32 support for the new scheduler as well.
4782 Affected file lib/silcutil/win32/silcwin32schedule.c.
4784 * Fixed the SHA1 implementation to work on various platforms.
4786 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4788 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4789 API. It is part of the scheduler now. Everything else is
4790 as previously but some functions has changed their names.
4791 Checkout the lib/silcutil/silcschedule.h for the interface.
4792 Updated all applications to use the new interface. Affected
4793 files are lib/silcutil/silcschedule.[ch].
4795 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4797 * Found a bug in the SKE implementation. The HASH value,
4798 specified by the protocol, was not computed correctly. The
4799 public key of the responder was not added to the computation
4800 even though it is mandatory. Affected file lib/silcske/silcske.c.
4801 This unfortunately causes incompatibilities with older
4802 clients and servers.
4804 * Added WIN32 specific network init and uninit functions:
4805 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4806 the Winsock2. Affected file lib/silcutil/silcnet.h and
4807 lib/silcutil/win32/silcwin32net.c.
4809 * Set the socket always to nonblocking mode on WIN32 after
4810 reading data or writing data. Affected file is
4811 lib/silcutil/win32/silcwin32sockconn.c.
4813 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4815 * Fixed various compilation problems under WIN32. Affected
4816 files lib/silcutil/win32/silcwin32thread.c and
4817 lib/silcutil/win32/silcwin32schedule.c.
4819 * Removed all _internal.h #includes from public header
4820 files. Internal headers must never be included from
4823 Removed also the lib/silcske/payload_internal.h file.
4825 * All include files that may be needed (public and some others
4826 included by the public headers) by application developers are
4827 now copied to the ./includes directory. It does not copy any
4828 internal headers. Affected file Makefile.defines.pre and all
4829 Makefile.am's under lib/ and subdirs.
4831 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4833 * Do not change the ~/.silc directory's permissions automatically.
4834 Affected file irssi/src/silc/core/clientutil.c.
4836 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4838 * Do not cancel the protocol in silc_server_close_connection
4839 it might cause recursion. Now cancelled in the function
4840 silc_server_free_sock_user_data. Affected file silcd/server.c.
4842 * Fixed the silc_server_remove_clients_by_server to regenerate
4843 the channel keys correctly finally. Added also new function
4844 silc_server_remove_clients_channels to actually do it.
4845 Affected file silcd/server.c.
4847 * Fixed the silc_server_new_channel to not crash by giving
4848 wrong router to the new channel. Affected file is
4849 silcd/packet_receive.c.
4851 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4853 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4854 which is given as argument to the silc_client_alloc now.
4855 It can be used to configure the client and set various parameters
4856 that affect the function of the client.
4858 * The USERS command in server did not check whether the channel
4859 is private or secret. Affected file silcd/command.c.
4861 * Added new argument to the USERS command in protocol specification.
4862 The USERS command now can take the channel name as argument
4863 as well. Added support for this in client and server and
4864 updated the protocol specs.
4866 * Completed the GETKEY command in client. It can be now used
4867 to fetch also servers public key not only some clients.
4868 Affected files lib/silcclient/command[_reply].c.
4870 * Added silc_client_get_server to return server entry by the
4871 server name. Affected files lib/silcclient/silcapi.h and
4874 * Redefined the IDENTIFY command in protocol specification to be
4875 more generic. It now can be used to query information about
4876 any entity in the SILC Network, including clients, servers and
4877 channels. The query may be based either the entity's name
4878 or the ID. Added support for this in both client and server.
4880 Affected files silcd/command.c and lib/silcclient/command.c
4881 and command_reply.c.
4883 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4884 the _from_client and _from_server functions. Affected file
4887 * Added silc_client_get_channel_by_id_resolve to the file
4888 lib/silcclient/silcapi.h to resolve channel information by
4889 its ID. Added also silc_client_get_channel_by_id that
4890 does not resolve it from the server.
4892 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4894 * Added SilcServerEntry context into the client library
4895 to represent one server. The INFO command now allocates
4896 these to save the resolved server info. For now on the
4897 client library will also keep information about servers,
4898 connected and resolved with INFO.
4900 The INFO command now allocates the SilcServerEntry context
4901 and saves the server info there. The COMMAND_REPLY in
4902 the INFO now returns the parameters to application in
4903 same order as defined in the protocol specification.
4905 The entries are cached in the client->server_cache.
4907 * The INFO command is now issued after received the Client ID
4908 from the server. Affected file lib/silcclient/client.c.
4910 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4911 to the application as the mode changer might be server.
4912 It is guaranteed that NULL is not returned anymore to the
4913 application. Affected file lib/silcclient/client_notify.c.
4915 The ID Type is now also passed to the application so that
4916 it can check whether the returned entry is SilcClientEntry
4919 Added new function silc_client_get_server_by_id to return
4920 the server entry by ID. Affected files are the
4921 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4923 * Do not create the channel in the Irssi SILC Client when issuing
4924 the JOIN command but when received the sucessful JOIN command
4925 reply. Otherwise the channel might get created even though we
4926 could not join it. The Affected file is
4927 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4929 * Fixed a channel joining bug in router. The router must also
4930 check the channel modes, invite and ban lists etc. when serving
4931 the JOIN command sent by normal server. Affected file is
4932 silcd/command.c. The router now resolves the client's
4933 information from the server who sent the JOIN command if it
4934 does not know it, and processes the JOIN command only after
4937 * Changed the SilcCommandCb to take new argument; void *context2.
4938 Affected file lib/silccore/silccommand.h
4940 The second argument in the command callbacks in the server now
4941 includes the SilcServerCommandReplyContext if the command was
4942 called as pending command callback from the command reply.
4943 Otherwise it is NULL. When called as pending the status of the
4944 command reply will be checked and if it was erronous the
4945 error will be sent to the original sender of the command.
4946 This way the client always receives the error messages even
4947 though the server was actually the one who received the error
4948 when it resent the command to router, for example. Affected
4949 files silcd/command[_reply].[ch].
4951 * Fixed sending WHOWAS command's error message to client if
4952 the requested client could not be found. It was missing.
4955 * Changed the CMODE and CUMODE commands reply arguments in the
4956 protocol specification. The Channel ID is now sent in both
4957 of the commands to identify the channel. Implemented this
4958 new feature to the client and server. Affected files
4959 lib/silcclient/command_reply.c and silcd/command.c.
4961 * Made better checks for invite and ban lists in the JOIN
4962 command in server. Affected file silcd/command.c.
4964 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4966 * The server now performs the incoming host IP/DNS lookup
4967 using the silc_socket_host_lookup and thus does not block
4968 the server anymore. Affected file silcd/server.c.
4970 * Completed the multi-thread support for SILC Scheduler in
4971 the lib/silcutil/silcschedule.c.
4973 * Fixed the configure.in.pre to detect the pthread correctly
4976 * Fixed a deadlock in silc_task_queue_wakeup in the file
4977 lib/silcutil/silctask.c.
4979 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4981 * Added new function silc_schedule_wakeup that is used in
4982 multi-threaded environment to wakeup the main thread's
4983 schduler. It needs to be used when a thread adds a new task
4984 or removes a task from task queues. After waking up, the
4985 scheduler will detect the task queue changes. If threads
4986 support is not compiled in this function has no effect.
4987 Implemented the wakeup mechanism to both Unix and WIN32
4988 systems. Affected files are lib/silcutil/silcschedule.[ch],
4989 lib/silcutil/unix/silcunixschedule.c and the
4990 lib/silcutil/win32/silcwin32schedule.c.
4992 * Added new function silc_task_queue_wakeup to wakeup the
4993 scheduler by the specified task queue. Affected file
4994 lib/silcutil/silctask.[ch].
4996 * The silc_socket_host_lookup_start now wakes up the scheduler
4997 after adding the timeout task. Affected file is
4998 lib/silcutil/silcsockconn.c.
5000 * The silc_socket_host_lookup is synchronous now if the threads
5001 support is not compiled in. However, the callback is still
5002 called asyncronously through the scheduler, anyway. Affected
5003 file lib/silcutil/silcsockconn.c.
5005 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5007 * Added new function silc_socket_host_lookup to perform
5008 asynchronous IP and FQDN lookups for the socket connection.
5009 Affected files lib/silcutil/silcsockconn.[ch].
5011 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5013 * Added SILC_MUTEX_DEFINE to define the mutex on environments
5014 that may or may not compile the mutex support in.
5016 Changed the silc_mutex_alloc interface. It allocates the
5017 mutex now to the sent pointer and returns TRUE or FALSE.
5019 Affected file lib/silcutil/silcmutex.h.
5021 * Wrote the SILC Task Queue interface to support multi-threads.
5022 Affected file lib/silcutil/silctask.[ch].
5024 * Wrote the SILC Scheduler to support multi-threads. Affected
5025 file lib/silcutil/silcschedule.c.
5027 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5029 * Implemented the SILC Mutex API and SILC Thread API for WIN32
5030 in lib/silcutil/win32/.
5032 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5034 * Defined SILC Mutex API and SILC Thread API and implemented
5035 them for Unix. Affected files are
5036 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
5037 lib/silcutil/unix/silcunixmutex.c and
5038 lib/silcutil/unix/silcunixthread.c.
5040 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5042 * Fixed the silc_server_remove_clients_by_server's channel
5043 key re-generation. The hash table handling was incorrect
5044 and would not work with many channels. Affected file is
5047 * Fixed some memory leaks around the server code.
5049 * Rewrote the silc_server_get_users_on_channel to support IPv6
5050 based Client ID's. Affected file silcd/server.c.
5052 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
5053 specification. However, a separate document must be written
5054 to define the detailed signing procedure and the payload
5055 associated with the flag. Defined the flag to the
5056 lib/silccore/silcchannel.h as well.
5058 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5060 * Changed the dynamic tables to static size tables in the
5061 lib/silccrypt/silchmac.c.
5063 * Removed GCC dependencies from the code. A patch by cras.
5065 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5067 * Do not show the error "Error receiving packet bla bla"
5068 in server if it really was not an error (-2 means that reading
5069 is pending). Affected file silcd/server.c.
5071 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5073 * Fixed a possible crash in silc_server_remove_clients_by_server
5074 in silcd/server.c. Fixed there also some memory leaks.
5076 * Fixed the silc_idlist_replace_client_id. It could replace
5077 wrong key in the hash table. Affected file silcd/idlist.c.
5079 * Do not check whether there are global users on the channel
5080 if the channel->global_users is FALSE. Affected functions
5081 silc_server_remove_from_one_channel and
5082 silc_server_remove_from_channels in silcd/server.c. Also,
5083 do not check if the removed client is local as we can be
5084 sure that global client was not removed from the channel
5085 and checking for global users is not needed.
5087 * The silc_server_remove_clients_by_server now re-generates
5088 the channel keys correctly for those channels that had
5089 clients removed from them. Affected file silcd/server.c.
5091 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5093 * Found the reason of random crashes in the server. We weren't
5094 ignoring the SIGPIPE signal (which can be sent in write())
5095 and it crashed the server. Affected file silcd/silcd.c.
5097 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5099 * Assure that sock->user_data is not NULL in the function
5100 silc_server_packet_send in silcd/packet_send.c.
5102 * Disconnect the remote connection if it could not be added
5103 to any ID lists in the server. The affected file is
5106 * Check in silc_server_packet_send[_real/dest] that the
5107 socket is not disconnecting and ignore the data if it is.
5108 Affected file silcd/packet_send.c.
5110 * Define inline to __inline on native WIN32 compilation.
5111 Affected file includes/silcwin32.h.
5113 * Added some explicit type casts for inline code since MSVC
5114 require them. Affected files lib/silcutil/silcbuffer.h,
5115 lib/trq/silcdlist.h and lib/trq/silclist.h.
5117 * Print warning in log files from now on if the packet
5118 decryption fails. Affected file silcd/server.c.
5120 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5122 * Changed the `say' client operation's interface to accept
5123 new `type' argument to indicate the type of the message sent
5124 by the library. The application may filter the library's
5125 messages according the type. The affected file is the
5126 lib/silcclient/silcapi.h.
5128 * Added two new functions to lib/silcclient/silcapi.h:
5129 silc_client_del_client and silc_client_del_client_by_id.
5130 Affected file lib/silcclient/idlist.c.
5132 * Moved the clientincludes.h from includes/ to silc/ and
5133 serverincludes.h from includes/ to silcd/.
5135 * The modes for the CMODE and CUMODE are now passed as
5136 uint32 for application with COMMAND_REPLY. The affected
5137 file is lib/silcclient/command_reply.c.
5139 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5141 * /WHOIS without arguments shows client's own information.
5142 Affected file lib/silcclient/command.c.
5144 * Changed PING to not accept any arguments. The specs
5145 says that client can ping only the connected server so
5146 requiring an argument is not needed. Affected file is
5147 lib/silcclient/command.c.
5149 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5151 * Fixed a fatal bug in private message sending and reception
5152 encryption and decryption when using private message keys.
5153 The implementation was incorrect and did not follow the
5154 specification. It causd that some of the message were
5155 lost since it did not use the sending and receiving keys
5156 as the protocol suggests. This has been fixed and will cause
5157 incompatibilities with older clients when sending private
5158 message encrypted with private message keys. Affected files
5159 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
5160 and various other in Irssi SILC Client.
5162 Added `responder' boolean argument to the functions
5163 silc_client_add_private_message_key[_ske] to indicate when
5164 the key is added as responder or initiator of the key
5167 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5169 * Removed the silc_ske_check_version function and created
5170 a SilcSKECheckVersion callback. Added also a function
5171 silc_ske_set_callbacks that is now used to set all SKE
5172 callbacks. The callback functions are not given to
5173 the SKE functions anymore, but this function is used to
5176 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
5178 * Added `silc_version' argument to the silc_client_alloc
5179 to define the version of the application for the library.
5180 The library will use the version string to compare it
5181 against the remote host's (usually a server) version
5182 string. Affected file lib/silcclient/silcapi.h
5184 * Added the KE protocol context to Key Agreement context
5185 in client library so that we can abort the SKE if it
5186 is in process when we get timeout. Affected file is
5187 lib/silcclient/client_keyagr.c.
5189 * Do not resolve the client ID forever if it returns in the
5190 first time that such client does not exist. This was done
5191 for example with private message. Affected file is
5192 lib/silcclient/client_prvmsg.c.
5194 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5196 * Do not add regex.h for WIN32. The affected file
5197 includes/silcincludes.h.
5199 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
5200 not work yet 100%. It generates the DLL's automatically
5201 when compiling with --with-win32 under cygwin.
5203 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5205 * lib/contrib/regex.c is not compiled on WIN32.
5207 * Added silc_net_get_socket_opt function to the
5208 lib/silcutil/silcnet.h.
5210 * Added includes/silcwin32.h for WIN32 specific includes
5213 * Do not use ptime structure or any of the posix process
5214 functions on WIN32 in lib/silccrypt/silrng.c.
5216 * Added silc_gettimeofday to provide generic function
5217 for struct timeval on all platforms. Added the function
5218 to lib/silcutil/silcutil.h.
5220 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5222 * Moved the lib/silccore/silcsockconn.[ch] to the utility
5223 library as they clearly belong there. As a plus side we
5224 can make the actual socket connection routines platform
5227 Added also new generic function silc_socket_read and
5228 silc_socket_write (that used to be silc_packet_[read/write].
5229 The implementation of these are platform specific.
5231 * Added WIN32 specific routines of silc_socket_[read/write]
5232 to lib/silcutil/win32/silcwin32sockconn.c.
5234 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5236 * Added preliminary support for native WIN32 compilation under
5237 cygwin (using the -mno-cygwin option for GCC) to the
5238 ./configure.in.pre. The --with-win32 now prepares the
5239 compilation for native WIN32.
5241 * Rewrote the SILC Scheduler interface in the file
5242 lib/silcutil/silcschedule.h. The scheduler is now context
5243 based and does not have anymore any global static scheduler.
5244 Moved the Unix scheduler to the lib/silcutil/unix/ directory
5245 and created lib/silcutil/win32 directory for WIN32 based
5248 * Added Unix specific network routines to the
5249 lib/silcutil/unix/silcunixnet.c and the old
5250 lib/silcutil/silcnet.c includes now only generic routines.
5252 Added WIN32 specific network routines to the
5253 lib/silcutil/win32/silcwin32net.c.
5255 * Added Unix specific utility functions from the
5256 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
5258 * Added WIN32 SILC Scheduler to the file
5259 lib/silcutil/win32/silcwin32schedule.c. The code is of course
5262 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5264 * Do not handle JOIN notify in the server if the target client
5265 is not registered (idata->registered == FALSE). The affected
5266 file is silcd/packet_receive.c.
5268 * Update the nickrec->founder in event_cumode in the Irssi SILC
5269 client. Affected file irssi/src/silc/core/silc-channels.c.
5271 * Fixed the CUMODE_CHANGE notify handling in the server when
5272 server and router are announcing their clients on channels.
5273 Now the mode changes are saved and notified correctly. The
5274 affected file is /silcd/packet_receive.c.
5276 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
5277 They really did not replace the cache entry in the ID Cache.
5278 Now they do that. Affected file silcd/idlist.c.
5280 * Fixed the KICK notify handling in the Irssi SILC client to
5281 update the channel records so that the kicked client does not
5282 appear to be on the channel. The affected file is
5283 irssi/src/silc/core/silc-channels.c.
5285 * Always update the conn->current_channel when executing command
5286 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
5288 * Fixed the KILL notify handling in Irssi SILC client to remove
5289 the killed client on all channels.
5291 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5293 * Fixed the silc_parse_command_line to remove extra spaces
5294 from the start and end of the arguments. Affected file is
5295 lib/silcutil/silcutil.c.
5297 * Cancel and free any active protocol in the function
5298 silc_server_close_connection. Affected file silcd/server.c.
5300 * Cancel and free any active protocol in the function
5301 silc_client_close_connction. Affected file is
5302 lib/silcclient/client.c.
5304 * Do not execute the KILL command for clients that are in
5305 history (ie. they are not in the network). Affected file is
5308 * Fixed KILL notify handling, client does not crash anymore.
5309 Affected file irssi/src/silc/core/silc-channels.c.
5311 * Reduced the default packet buffer size from 2048 to 1024 in
5312 lib/silccore/silcpacket.c.
5314 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5315 counter to the SKE context that is incresed when the SKE library
5316 performs async operation outside the library. If the outside
5317 process frees the SKE context and FREED status will be set
5318 and the library will detect after the sync operation that the
5319 libary is freed. The affected files are
5320 lib/silcske/silcske[_status].[ch].
5322 * Resolve the client entry information in the function
5323 silc_client_channel_message to assure that NULL pointer is not
5324 passed as client entry to the application. */
5326 * Fixed the task timeout calculation to assure that there is
5327 never negative timeouts. The affected file is
5328 lib/silcutil/silcschedule.c.
5330 * Fixed the channel user mode notification sending in server.
5331 It was sent point-to-point to the router (or to server by router)
5332 but it needs to be destined to a channel. The routines now
5333 supports sending the channel user mode notifys to the channels
5334 when announcing clients and channels. Affected files are
5335 silcd/server.c and silcd/packet_receive.c.
5337 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5338 It did not actually replace the old channel entry in the cache.
5339 Affected file lib/silcclient/client_notify.c.
5341 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5343 * Fixed a possible crash in silc_packet_send_prepare. It now
5344 assures always that there is enough space in the buffer and
5345 at the tail area of the buffer (for MAC).
5347 Fixed the inbound buffer reallocation in silc_packet_read.
5348 It was old code and did not handle the reallocation correctly.
5351 The affected file is lib/silccore/silcpacket.c.
5353 * Fixed buffer overflow in silc_parse_nickname in the file
5354 lib/silcutil/silcutil.c.
5356 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5358 * make install generates new server keys only if there is not
5361 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5363 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5364 Added check that if the NOREPLY is set then we will not send
5365 the away message. This avoids infinite loop of away messages
5366 if both clients are away. The affected file is
5367 lib/silcclient/client_prvmsg.c.
5369 * Fixed client crash if /NICK was given without arguments.
5370 Affected file lib/silcclient/command.c.
5372 * Server does not send the invite list in INVITE command back
5373 to the client if the list was not altered. Added this notion
5374 to the protocol spec as well. Affected file silcd/command.c.
5376 Fixed possible crash in INVITE command by checking the
5377 value of silc_server_get_client_route command.
5379 * Fixed the INVITE notify type handling. The arguments are now
5380 taken in correct order and client does not crash. The affected
5381 file is irssi/src/silc/core/silc-channels.c.
5383 Removed the "Inviting xxx to channel" message from the
5384 client library away and let the application handle it.
5385 Affected file lib/silcclient/command.c. Added that message
5386 to Irssi SILC client's message formats.
5388 * Fixed CMODE command crash in client. It now checks the
5389 amount of arguments correctly and does not crash. The affected
5390 file is lib/silcclient/command.c.
5392 * Do not create new channel automatically in silc_channels_join
5393 but check whether the channel by that name already exists.
5394 Affected file irssi/silc/core/silc-channels.c.
5396 * Do not send the SERVER_SIGNOFF to router if the disconnected
5397 entity was the router. Affected file silcd/server.c.
5399 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5400 SILC client as it was missing from there.
5402 Added the handling of the KICK notify to the Irssi SILC client
5403 as it was missing. Added "you have been kicked" message to
5404 Irssi SILC client's message modules formats.
5406 Added the handing of the KILL notify to the Irssi SILC client
5407 as it was missing. Added the kill message module formats
5410 The affected file is irssi/src/silc/core/silc-channels.c.
5412 * The router did not save the channel mode the server announced.
5413 Affected file silcd/packet_receive.c.
5415 * Fixed a possible crash in INFO command in server. If the
5416 server did not provide the server info it crashed. Affected
5417 file silcd/command.c.
5419 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5421 * Fixed the GETKEY command in the server to check also the
5422 global list. Otherwise the GETKEY would not work correctly
5423 in normal SILC server. Affected file silcd/command.c.
5425 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5427 * Fixed GETKEY crash, it crashed if the command did not succseed.
5429 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5431 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5432 is now real and not just an macro interface to GMP.
5434 Removed the entire GMP from the source tree and imported new
5435 NSS MPI library instead. Reason for removing GMP is that it is
5436 extremely large and compiles extremely slow. The NSS MPI
5437 is only a few files and compiles in less than 10 seconds.
5438 The speed is also about the same as GMP. The MPI is imported
5439 to lib/silcmath/mpi.
5441 If the system has GMP installed we will still use the GMP.
5442 If it is not then the NSS MPI will be compiled.
5444 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5446 * Merged a long nickname (127 characters long) crash bugfix from
5447 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5449 * Merged a freed memory reference bugfix from Irssi CVS tree.
5450 Affected file irssi/src/core/commands.c.
5452 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5454 * Added the server's public key sving and verification to the
5455 server when performing the SKE. This was missing and the
5456 remote server's (or router's) public key was accepted without
5457 checking whether we have it previously or trust it at all.
5458 Affected file silcd/protocol.c.
5460 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5462 * Check in the silc_server_timeout_remote if protocol is active
5463 and make sure that the protocol's final callback is called so
5464 that all memory if freed. Affected file silcd/server.c.
5466 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5468 * silc_server_whois_send_reply crashed the server if the nickname
5469 was 127 characters long. Affected file silcd/command.c.
5471 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5473 * Added sanity check to the silc_server_new_client. If the hostname
5474 is provided inside username then check that the provided hostname
5475 really is the same as the resolved one. If the hostname was not
5476 resolved then check it from the public key. Affected file is
5477 silcd/packet_receive.c.
5479 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5480 if the server disconnected us and the connection is not valid
5481 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5483 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5484 the library to the lib/silcutil/silcutil.[ch].
5486 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5488 * Close log file after open. Affected file
5489 lib/silcutil/silclog.c.
5491 * Check whether sock == NULL in silc_client_send_packet and return
5492 if it is. Affected file lib/silcclient/silcclient.c.
5494 * Check rec->entry == NULL in the Irssi SILC Client before
5495 sending the channel message. Affecte file is
5496 irssi/src/silc/core/silc-servers.c.
5498 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5500 * Merged a splitted window bugfix from Irssi CVS tree. The
5501 affected file is irssi/src/fe-text/textbuffer-view.c.
5503 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5504 It did not print nickname.
5506 * Improved the distributions system a bit.
5508 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5510 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5511 irssi/src/fe-text/gui-window.c.
5513 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5514 to in-active server. The affected file is
5515 irssi/src/silc/core/client_ops.c.
5517 * Resolve the client in USERS command reply if the entry does
5518 not have username resolved. The affected file is
5519 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5520 command to WHOIS command to really resolve stuff. The USERS
5521 is not used any more in any critical section so WHOIS can
5522 be used even though it might be slower than IDENTIFY.
5524 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5527 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5529 * Changed the protocol API a bit more consistent in the
5530 lib/silccore/silcprotocol.[ch].
5532 * Changed the following headers to ROBODoc format:
5534 lib/silccore/silcpayload.h
5535 lib/silccore/silcprotocol.h
5536 lib/silccore/silcsockconn.h
5538 All core library headers are now formatted.
5540 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5542 * Fixed a bug in Irssi SILC client; do not show that you are
5543 server/router operator if you really are not. Affected file is
5544 irssi/src/silc/core/client_ops.c.
5546 * Renamed silc_command_free_payload to silc_command_payload_free.
5547 Affected file lib/silccore/silccommand.h
5549 * Added silcmath.h to include the prototoypes of various routines
5550 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5553 * Changed the following headers to ROBODoc format:
5555 lib/silccore/silcchannel.h
5556 lib/silccore/silccommand.h
5557 lib/silccore/silcid.h
5558 lib/silccore/silcidcache.h
5559 lib/silccore/silcmode.h
5560 lib/silccore/silcnotify.h
5561 lib/silccore/silcpacket.h
5562 lib/silcmath/silcmath.h
5564 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * Added checking to the server code not to start the server if
5567 ciphers and stuff are not configured properly. Affected files
5568 silcd/serverconfig.[h] and silcd/server.c.
5570 * Changed the layout of the header files of the public interfaces
5571 in the SILC libraries. The new layout supports ROBODoc
5572 documentation tool (and some others) so that it is easy to create
5573 a library reference manual. All the other headers and source
5574 code must still follow the CodingStyle document. Also source
5575 code must not include these ROBODoc stuffs, only the headers.
5576 Furthermore, all public interface headers must now be named
5577 by using `silc' prefix, example: silcapi.h, silccipher.h.
5578 Some files were renamed due to this. All the other headers
5579 must not be used as public interfaces. I will update the
5580 CodingStyle document later. Changed following headers, so far:
5582 lib/silcclient/silcapi.h
5583 lib/silccore/silcauth.h
5584 lib/silccore/silcprivate.h
5585 lib/silccrypt/silcdh.h
5587 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5591 * Removed silc_client_packet_send_flush from the client library
5592 as it is not needed. Affected file lib/silcclient/client.[ch].
5594 * Added printing of message of unresolved authentication method
5595 to the Irssi SILC client. Added it to the module formats.
5596 Removed the same message from the client library.
5598 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5600 * Added new distribution feature, DISTLABEL. Every distribution
5601 can define own preprocessor label that can be used in the
5602 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5603 file distributions, acconfig.h.pre and prepare.
5605 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5607 * Added Makefile.defines_int to include the actual definitions
5608 for Makefile.defines.in. Tested the new distribution system,
5609 created distributions and tested installation.
5611 * Added AWAY message printing to the Irssi SILC client. Added
5612 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5614 * Added SCONNECT command to call the SILC's CONNECT command.
5615 Cannot use CONNECT directly since Irssi uses that internally.
5616 Affected file irssi/src/silc/core/silc-servers.c.
5618 Added ACTION local command. It is same as ME command but takes
5619 the channel as mandatory argument.
5621 Rewrote some of the Irssi's help files to suite for SILC
5624 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5626 * Added Makefile.defines[.in] that should for now on be included
5627 in all Makefile.am file in the source tree. That file includes
5628 all common compilation definitions for SILC source tree.
5630 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5632 * Minor changes to the ./prepare script to change the package
5633 name according the distribution name to the configure.in.
5635 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5637 * Created new distribution system. Added file `distributions'
5638 that defines all the distributions that can be created out of
5639 the SILC source tree. The ./prepare script now reads that
5640 file to determine how to prepare the distributions. The
5641 first argument to the ./prepare is the name of the distribution
5642 and second is the version of the distribution. If given
5643 without arguments it creates the default (toolkit) distribution
5644 with the default version (defined in ./prepare).
5646 All Makefile.am files that are subject to the distributions
5647 are now named as Makefile.am.pre. These are ./Makefile.am
5648 and lib/Makefile.am. Others may be changed later.
5650 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5652 * Added invite list, ban list, some key management and connection
5653 error message printing to module formats in the Irssi SILC client.
5655 * Added new silc_client_set_away_message to set the away message
5656 that is back to the person who sent private message. The
5657 affected file lib/silcclient/silcapi.h and the
5658 lib/silcclient/client_prvmsg.c.
5660 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5662 * Fixed the private message sending in the Irssi SILC client,
5663 added local command KEY to the Irssi SILC client.
5665 Added key management and key agreement message formats to the
5666 irssi/src/fe-common/silc/module-formats.[ch].
5668 Added USERS (alias WHO) printing, server/router operator
5669 indication and LIST command printing to the module formats.
5671 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5673 * Fixed channel joining notify handling, cumode notify handling
5674 from Irssi SILC client.
5676 * Added SILC specific module-formats to the Irssi SILC client so
5677 that SILC specific message hilighting, colors etc is possible.
5678 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5680 Added channel mode, channel user mode, actions, notices,
5681 whois and whowas printing to the the module-formats.c.
5683 * Fixed a bug in channel deletion in the server. The channel
5684 is not left to the cache even if the channel founder auth mode
5685 is set when there are no users anymore on the channel. Affected
5686 file silcd/server.c.
5688 * The silc_net_localhost now resolves the entire hostname including
5689 the domain name. Affected file lib/silcutil/silcnet.c.
5691 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5693 * Changed the ask_passphrase client operation to be ascynchronous.
5694 It has now a completion callback and a context that the
5695 application must call after it has got the passphrase from
5696 the user. Affected files lib/silcclient/silcapi.h,
5697 lib/silcclient/protocol.c, lib/silcclient/command.c and
5700 Added SilcAskPassphrase callback that the application calls
5701 to deliver the passphrase to the library.
5703 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5704 The public key verification and especially a certificate
5705 verification is asynchronous procedure.
5707 Added new SILC_SKE_STATUS_PENDING status to indicate the
5708 request is pending and a callback will be called to finalize
5711 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5712 indicate that remote end did not send its public key (or
5713 certificate), even though we require it. Added check for this
5714 condition in the SKE. This was a security bug, now fixed.
5716 Defined new SilcSKEVerifyCbCompletion callback that is called
5717 when the verification process is completed.
5719 The affected files lib/silcske/silcske_status.h and
5720 lib/silcske/silcske.[ch].
5722 * Changed the verify_public_key client operation to be async
5723 as well. Defined SilcVerifyPublicKey callback that is used to
5724 indicate the success of the public key verification process.
5726 Changed the server and client to use the new async client
5729 * Changed the Irssi SILC client's internal scheduler to be called
5730 twice as many times as it used to be. As a result the client
5731 should be a bit faster now. Affected file is
5732 irssi/src/silc/core/silc-core.c.
5734 * Added support to Irssi SILC client of asynchronous public key
5735 verification and passphrase inquiry. Affected file is
5736 irssi/src/silc/core/silc-core.c.
5738 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5740 * Do not say "You have left channel %s" in client library.
5741 Moved it to the application. Affected files are
5742 lib/silcclient/command.c and silc/client_ops.c.
5744 * Fixed silc_client_get_clients. Command context was not
5745 duplicated and was freed memory in the callback. Affected
5746 file lib/silcclient/idlist.c.
5748 * Do not say "you are now talking..." on JOIN command in the
5749 client library. The appliation must handle it.
5751 * Do not say ".. changed topic to" in command reply in the
5752 client libary. The application must handle it.
5754 * Fixed TOPIC command sending in the client library.
5756 * Fixed a memory leak in silc_client_command_free in the file
5757 lib/silcclient/command.c.
5759 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Imported a modified version of Irssi client to the source tree.
5762 The Irssi will be used to create a new client called
5763 Irssi SILC. Imported to irssi/.
5765 Added silc_core_init_finish function to the Irssi. Affected
5766 file irssi/configure.in.
5768 A lot changes in the Makefile.ams around the irssi tree.
5770 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5772 * Do not rehash if the new size is same as the old size of the
5773 hash table, in the silc_hash_table_rehash*. The affected file
5774 lib/silcutil/silchashtable.c.
5776 * Replaced hash_table_del_by_context calls from the server
5777 (when channel->user_list and client->channels) to the
5778 hash_table_del as it is sufficient and faster.
5780 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5782 * Added silc_hash_table_list, silc_hash_table_get and the
5783 SilcHashTableList structure to provide an alternative way to
5784 traverse the hash table. The affected files are
5785 lib/silcutil/silchashtable.[ch].
5787 * Changed the server's idlist routines to use the hash table
5788 routines to optimize the code.
5790 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5792 * Replaced the client entry's `channel' list and channel entry's
5793 `user_list' list to hash tables for optimized lookup. Changed
5794 the code to use the hash table interface around the code.
5795 Affected file lib/silcd/idlist.[ch].
5797 * Added `auto_rehash' boolean argument to the function
5798 silc_hash_table_alloc to indicate whether the hash table should
5799 auto-rehash when it thinks is appropriate time. It will
5800 increase the hash table size if the there is twice as much
5801 entries in the table than the size of the table, and will
5802 decrease the size if there are twice as less entries than
5803 the size of the table.
5805 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5807 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5809 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5811 * silc_idcache_purge_by_context deletes the entry now by context
5812 as it is supposed to do. Affected file lib/silccore/idcache.c.
5814 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5815 client is not anymore valid (WHOWAS givens the info) and not
5816 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5818 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5820 * Removed the `data' and `data_len' arguments from the ID Cache
5821 interfaces and added `name' argument. ID Cache does not handle
5822 anymore the binary data only a names associated with given ID.
5824 * When hashing a Client ID with silc_hash_id the entire ID is
5825 not hashed anymore, instead only the hash of the Client ID is
5826 hashed. This way we can access the Client ID from the cache
5827 with Client ID but with the hash of the ID (which is a hash of
5828 the nickname) as well without any difference in performance.
5830 Added also silc_idcache_find_by_id_one_ext to do one on one
5831 searching when we have the actual ID. Added also function
5832 silc_hash_client_id_compare. The affected files are
5833 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5835 * When hashing the name associated with a ID it is always done
5836 in lowercase. This way we can access the cache without worrying
5837 about case-sensitivity, even though, for example nicknames are
5840 * Fixed a bug in server with channel message sending. It put
5841 wrong ID type as destination ID. The affected file
5842 silcd/packet_send.c.
5844 * silc_idcache_del_by_context now deletes from all hash tables
5845 by context. Affected file lib/silccore/idcache.c.
5847 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5849 * Changed the client library to use the new ID Cache interface.
5850 Changes around the source tree.
5852 * Added silc_hash_table_rehash_ext to rehash with specific
5853 hash function. Affected file lib/silcutil/silchashtable.[ch].
5855 * Added silc_hash_string_compare to compare two strings in the
5856 hash table. Affected file lib/silcutil/silcutil.[ch].
5858 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5860 * Added new function silc_idcache_del_by_context into the
5861 lib/silccore/idcache.[ch].
5863 * Changed the server's ID list routines to use the new ID Cache
5864 interface. Changes around the source tree.
5866 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5868 * Added silc_hash_table_del[_by_context]_ext functions in to the
5869 lib/silcutil/silchashtable.[ch].
5871 Removed silc_hash_table_find_all* routines and added new
5872 silc_hash_table_find_foreach to replace them.
5874 Added silc_hash_table_replace_ext function as extended
5875 replacing function. Separated the simple hash table interface
5876 from the extended hash table interface in the file
5877 lib/silcutil/silchashtable.h.
5879 * Fixed minor bugs and changed it to use some of the new
5880 hash table functions in lib/silccore/idcache.c
5882 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5884 * Added new function silc_hash_table_find_all to return all keys
5885 in the hash table by the specified key. As the hash table is
5886 collision resistant it also makes it possible to have several
5887 duplicate keys in the hash table. This function may be used to
5888 find all of the keys from the hash.
5890 Added user_context arguments to the SilcHashFunction,
5891 SilcHashCompare and SilcHashDestructor to deliver user specified
5894 Added new fuctions silc_hash_table_find[_all]_ext to do
5895 extended lookup with specified hash and compare functions and
5896 specified user contexts.
5898 Added new function silc_hash_table_add_ext to add the key
5899 with specified hash function and user context.
5901 Added new function silc_hash_table_foreach to traverse all
5902 entrys in the hash table. Added SilcHashForeach callback
5905 Added new function silc_hash_table_del_by_context to delete
5906 the entry only if the context associated with the key matches.
5908 Affected files are lib/silcutil/silchashtable.[ch].
5910 * Removed silc_hash_[server/client/channel]_id and added just
5911 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5912 silc_hash_id_compare to compare two ID's using as the hash table
5913 comparison function. Added also silc_hash_data to hash
5914 binary data and silc_hash_data_compare to compare it.
5916 * Removed silc_idlist_find_client_by_hash as it is not needed
5917 anymore. Affected file silcd/idlist.[ch].
5919 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5920 to use internally the SilcHashTable. The new ID Cache is a lot
5921 faster than the old one. Some of the ID Cache interface was also
5922 rewritten and obsolete and stupid functions were removed.
5924 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5926 * Added entry_count field to the SilcHashTable to keep the number
5927 of the entries in the table. Implemented the function
5928 silc_hash_table_rehash. Added new function
5929 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5931 Fixed a minor bug in silc_hash_table_free.
5933 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5934 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5935 into the lib/silcutil/silcutil.[ch].
5937 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5939 * Implemented a collision resistant hash table into the
5940 lib/silcutil/silchashtable[ch]. See the header and the source
5941 for the SilcHashTable API.
5943 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5945 * Merged dotconf version 1.0.2 into lib/dotconf.
5947 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5949 * Do not compile anything in lib/silcsim/* if the SIM support
5950 is not enabled. The tree should now compile without problems
5953 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5955 * Compiled the SILC under cygwin. Compiled and tested briefly
5956 without problems. More tests needed. The SIMs didn't compile
5959 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5961 * Fixed possible crash in silc_get_username in the
5962 lib/silcutil/silcutil.c.
5964 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5966 * Fixed a va_arg in silc/client_ops.c.
5968 * Oops, RC5 routines were named AES and caused some problems
5969 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5971 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * Added new SilcIDIP structure into the lib/silccore/id.h and
5974 replaced the old `ip' fields from all SILC ID's to that type.
5975 This is a step towards IPv6 support.
5977 The silc_id_get_len takes now the ID as an extra argument.
5978 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5979 both IPv4 and IPv6 based ID's.
5981 The affected files are lib/silccore/id.[ch] and other files
5982 around the tree using these routines.
5984 * Removed the ID length arguments in server from various
5985 silc_server_send_notify_* routines -> they are not needed
5988 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5990 * Fixed memory leak in silc_encode_pem_file in the file
5991 lib/silcutil/silcutil.c.
5993 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5995 * Check minor version as well in the SKE. Affected files are
5996 silcd/protocol.c and lib/silcclient/protocol.c.
5998 * Added --identifier option to the server so that an identifier
5999 can be when creating the public key for the server. Affected
6000 file is silcd/silcd.c.
6002 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
6003 lib/silccrypt/silcpkcs.c.
6005 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6007 * Register default ciphers and stuff when using -C option with
6008 the server. Affected file sildc/silcd.c.
6010 * Put back the servers public key filename format, it is better
6011 than the new one. For now, the client keys are saved with the
6012 new filename format. The affected file silc/client_ops.c.
6014 * Implemented the Cipher API for the rest of the ciphers that
6015 did not implement it or implemented it the wrong way.
6017 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6019 * Register default ciphers and stuff when using the -S option
6020 in the client. Affected file silc/silc.c. Same also when
6021 creating new key pair with -C option.
6023 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6025 * Fixed the silc_verify_public_key client operation function to
6026 save the public keys differently. The fingerprint is now
6027 used as filename and not the hostname. This way also the
6028 client keys are saved uniquely and not with hostnames. The
6029 affected file is silc/client_ops.c.
6031 * Trimmed the silc_hash_fingerprint function to remove extra
6032 whitespaces from the end of the fingerprint. The affected
6033 file is lib/silccrypt/silchash.c.
6037 * Added silc_cipher_register_default function to register all
6038 default ciphers. It can be used when configuration files
6039 does not exist and the application does not want any specific
6040 ciphers in any specific order.
6042 The SilcDList is now used as silc_cipher_list dynamically
6043 allocated cipher list. Removed the static list all together
6044 and now all ciphers must be allocated to the dynamic list.
6045 The silc_cipher_alloc routine was changed to check only the
6048 All silc_cipher_* routines that used to return int returns
6051 The affected files lib/silccrypt/silccrypt.[ch].
6053 * The same thing was done to silc_hash_* as for silc_cipher_*
6054 routines. Affected files lib/silccrypt/silchash.[ch].
6056 * The same thing was done to silc_pkcs_* as for silc_cipher_*
6057 routines. Affected files lib/silccrypt/silcpkcs.[ch].
6058 Added also silc_pkcs_[un]register[_default] functions.
6059 Removed the data_context from the PKCS API.
6061 * Added silc_hmac_register_default function to register default
6062 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
6063 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
6064 to unregister all hmacs at once.
6066 * Register the default ciphers, hash functions, PKCSs and HMACs
6067 if client's configuration file does not exist. The affected
6070 * The client did not load the hash functions from the SIM
6071 modules at all. Added support for this. Affected file is
6072 silc/clientconfig.c.
6074 * When decoding public key with silc_pkcs_public_key_decode, check
6075 the supported algorithm only if PKCS are registered. Affected
6076 file lib/silccrypt/silcpkcs.c. The same was done with the
6077 silc_pkcs_private_key_decode.
6079 * Fixed the SILC List routines to keep the list always in order.
6080 It used to change the list's order when traversing the list but
6081 not it preserves the order. Affected file lib/trq/silclist.h.
6083 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6085 * Added the client library to use the SilcSocketConnection's
6086 reference counter (by silc_socket_dup) to prevent the bug that
6087 the socket object may be freed underneath async operation.
6089 * The name resolv library checking fixes in the configure.in.pre.
6092 * Created new version of the protocol drafts for future
6093 development. The -03 drafts are the ones that will be changed
6094 in the trunk now and the -02 will remain as they are.
6096 * Send list of CUMODE notifys to the router when announcing
6097 the channel users to the router. Affected file silcd/server.c.
6098 If the router receiving channel founder CUMODE for a channel
6099 that already has channel founder it will send CUMODE notify
6100 to the sender to remove the channel founder rights from the
6101 announced client. Affected file silcd/packet_receive.c.
6103 * The CUMODE notify may now use Server ID as well as the entity
6104 who changes the mode. Updated protocool specs.
6106 * Updated INSTALL and README files.
6108 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6110 * New web pages in the http://silc.pspt.fi. The pages was
6115 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6117 * Implemented the [DenyConnectin] config section in the server.
6118 Added silc_server_config_denied_conn to check whether incoming
6119 connection is denied. Affected file silcd/serverconfig.[ch].
6121 * Do not check the ports when checking the incoming configuration
6122 data if the port is 0, meaning any. Affected file is
6123 silcd/serverconfig.c.
6125 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6127 * Fixed buffer overflow in silc_string_compare in the file
6128 lib/silcutil/silcutil.c.
6130 * Fixed double free in silc_server_command_leave in the file
6133 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6135 * Fixed the version checking in the server. Affected file is
6138 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6140 * Fixed the configuration data fetching when accepting new
6141 connections in the server. Affected file silcd/server.c.
6143 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6145 * Added `sender_entry' argument to the function
6146 silc_server_packet_relay_to_channel so that we can check
6147 whether some destination actually belongs to the same route
6148 the sender belongs (ie, we must not resend the packet to the
6149 sender). Affected file silcd/packet_send.[ch].
6151 * Added `servername' field to the SilcClientEntry in the server
6152 to hold the name of the server where client is from. Affected
6153 file is silcd/idlist.h.
6155 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6157 * Moved the channel message encrypting in the router betwen
6158 router connections from silc_server_channel_message to the
6159 silc_server_packet_relay_to_channel since we want to check
6160 whether we have anybody channel before encrypting anything.
6161 Affected files silcd/packet_[receive/send].c.
6163 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6165 * Fixed the [AdminConnection] server config section to support
6166 multiple entries. Affected file silcd/serverconfig.c.
6168 * Added support into the server to check the validity of the
6169 incoming connection before executing any KE or authentication
6172 * The connection configuration is now saved to the KE and
6173 connection auth protocol contexts and not fetched anymore in
6174 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
6176 * The local hosts listenning address and port is also resolved
6177 now when starting the server. We want to have the socket object
6178 to include the real address and port for the listener. Added
6179 new function silc_net_check_local_by_sock into the files
6180 lib/silcutil/silcnet.[ch].
6182 * Fixed a broadcast bug in server -> do not broadcast if we
6185 * Fixed a routing bug. Do not route broadcast packets ever.
6186 Broadcast packets must be processed always and not routed since
6187 they may be destined to some other host than yourself and thus
6188 would get routed without no good reason. Affected file is
6191 * Added function silc_server_config_is_primary_route to check
6192 whether primary router connection has been configured (a router
6193 configuration that we are initiating). If there is not, we
6194 will assume that there is only two routers in the SILC network
6195 and we will use the incoming router connection as our primary
6196 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
6198 * Changed the order of the broadcasting. Broadcast _after_ the
6199 packet has been processed not before. Affected file is
6202 * Fixed a [ClientConnection] parsing bug. The port was never
6203 parsed correctly thus resulting to port 0. Affected file
6204 silcd/serverconfig.c.
6206 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
6207 argument and did not set the broadcast packet flag. Affected
6208 file silcd/packet_send.c. Fixed same bug in the function
6209 silc_server_send_notify as well.
6211 * If we receive NEW_ID packet for our own ID in the server, ignore
6214 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6218 * Removed the nickname from the Private Message Payload.
6219 Updated the code and the protocol specs.
6221 * Updated protocol specs for submitting to the IETF.
6223 * Tweaked the Random Number Generator a bit. Affected file
6224 lib/silccrypt/silcrng.c. Exported a new function
6225 silc_rng_[global]_add_noise which can be used to add more
6228 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6230 * Do not parse packets with different timeout when protocol
6231 is active -> may cause problem with rekey. Affected file
6234 * When server receives signoff notify it must not create
6235 new channel key if the client is on any channels since the
6236 sender of the signoff notify will create it.
6238 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6240 * Added printing of error messages during SKE protocol from the
6241 failure packet sent by server during SKE. Affected file
6244 * Removed the client's failure_callback handling with timeout
6245 and handle it immediately when received.
6247 * The SKE library returned wrong type in SUCCESS and FAILURE
6248 packets. They must be 32 bit MSB not 16 bit MSB.
6250 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6252 * Ok, rewrote the logic of the re-key and now it seems to work.
6253 I tested it on high traffic with frequent re-keys without
6254 problems. Added hmac_receive (and renamed hmac to hmac_send)
6255 in SilcClientConnection in lib/silcclient/client.h and
6256 in SilcIDListData in silcd/idlist.h. Also, removed the
6257 SilcPacketParserContext's cipher and hmac fields as they are
6258 not needed anymore and actually caused some problems when
6259 the ciphers and hmac's changed underneath the packet parser.
6261 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6263 * If re-key protocol is active then process the incoming packets
6264 synchronously since we must assure that icoming packets encrypted
6265 with the old key is processed before the new keys is set to
6266 use. This is true other packets than for REKEY packets.
6267 Affected file silcd/server.c. The same was done to client library
6268 as well, affected file lib/silcclient/client.c.
6270 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6272 * Fixed bug in client and server to accept the force send if
6273 the packet is send from silc_[server/client]_packet_process
6274 function. Otherwise the packets are never delivered, oops.
6276 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6278 * Disable force sending of packets when REKEY protocol is active.
6279 We must assure that no packet is sent directly when rekey is
6280 performed. All packets must be sent through packet queue.
6281 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
6282 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
6283 function is silc_[server/client]_packet_send_real to check
6286 * Replaced the SIM paths from example config files to
6287 /usr/local/modules. Also, make install creates now
6288 /usr/local/silc/logs directory to hold all the SILC server
6291 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6293 * Made the configure.in.pre work on Solaris. Patch by salo.

6302 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6304 * When MAC computation fails the silc_packet_decrypt returned 0
6305 even though it was supposed to return -1. Fixed this. The
6306 affected file is lib/silccore/silcpacket.c.
6308 * Do not replace the config files in /etc/silc (in make install)
6309 if they already exist. Affected file ./Makefile.am.
6311 * Do not send re-key packets immediately but through packet queue.
6312 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6314 * Changed silc_net_check_host_by_sock to return FALSE if the
6315 IP/DNS could not be resolved. Though, it returns the IP address
6316 now even if it could not resolve it (but returns also FALSE).
6317 Affected file lib/silcutil/silcnet.[ch].
6319 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6321 * Added silc_pkcs_decode_identifier to decode the public key's
6322 identifier. Affected file lib/silccrypt/silpkcs.[ch].
6323 Added also silc_pkcs_free_identifier. Added also new context
6324 SilcPublicKeyIdentifier.
6326 * Added -S option to the silc client. It is used to dump the
6327 contents of the specified public key file.
6329 * Changed the PKCS api to return the public key length when
6330 setting the public key.
6332 * Fixed a fatal bug in the public and private key file loading.
6333 Affected file lib/silccrypt/silcpkcs.c.
6335 * Execute the packet parsing for client with zero (0) timeout
6336 if the protocol is active. Affected file silcd/server.c.
6338 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6340 * Made the key generation options to the silcd program. Added
6341 -C option, equivalent to client's option.
6343 * Added new [ServerKeys] config section to the server. It
6344 configures the server's public and private key.
6346 * Defined generic Public Key Payload into the protocol
6347 specification to send specific type of public keys and
6350 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6351 public key or certificate.
6353 * Implemented the GETKEY command to the server and to the
6354 client library and on user interface.
6356 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6358 * Made preliminary `make install' work.
6360 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6362 * Added SilcServerRekey context into silcd/idlist.h.
6364 * Added the PFS support as defined in the specification to the
6365 SKE protocol. Affected files lib/silcske/*.c.
6367 * Added `ske_group' field to the SilcServerRekey context to hold
6368 the number of the SKE group that is used with PFS in re-key.
6369 Affected file silcd/idlist.h.
6371 * Added PFS re-key support to the server. Affected file is
6374 * Added silc_protocol_cancel to cancel execution of the next
6375 state of the protocol. Affected file is
6376 lib/silccore/silcprotocol.[ch].
6378 * Added the re-key support with and without PFS to the client
6379 library. Re-key is performed once in an hour, by default.
6381 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6382 Added silc_client_rekey_callback and silc_client_rekey_final.
6383 Affected files are lib/silcclient/protocol.[ch] and
6384 lib/silcclient/client.[ch].
6386 * Removed the `hmac_key' and `hmac_key_len' fields from the
6387 SilcClientConnection structure; not needed. Affected file is
6388 lib/silcclient/client.h.
6392 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6394 * Do not ask whether user wants to use the negotiated private key
6395 for private messages, just use it. Affected file is
6396 silc/local_command.c.
6398 * Added `send_enc_key' and `enc_key_len' fields to the
6399 SilcIDListData structure since they are needed in the re-key
6400 phase. Affected file is silcd/idlist.[ch].
6402 * Implemented the simple re-key protocol into the server.
6403 Affected files silcd/server.c and silcd/protocol.[ch]. The
6404 re-key will be performed once in an hour, by default.
6406 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6407 Added silc_server_rekey, silc_server_rekey_callback and
6408 silc_server_rekey_final.
6410 * Removed Tunneled flag from the protocol. Updated the code
6411 and the specifications.
6413 * Adde `pfs' field to the SilcIDListData to indicate whether
6414 the PFS is to be performed in the re-key. Affected file is
6417 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6419 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6420 int64 of at least the xintXX size. If void * is less that 4
6421 bytes uint32 * will be used. Defined bool as boolean.
6423 * Changed _ALL_ unsigned long and unsigned int to uint32,
6424 unsgined short to uint16 in the source tree.
6426 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6427 not handle clients that has entry->data.registered == FALSE.
6428 They are not in the network anymore. Affected file is
6431 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6433 * Implemented the sending of the SERVER_SIGNOFF notify in the
6434 server. Affected file is silcd/server.c.
6436 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6437 Added also silc_notify_payload_encode_args into the
6438 lib/silccore/silcnotify.[ch].
6440 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6441 Affected file silcd/packet_receive.c.
6443 * Implemented the SERVER_SIGNOFF notify handling in the client
6444 library. Affected file lib/silcclient/client_notify.c. Also,
6445 implemnted the printing of the SERVER_SIGNOFF info to the
6446 application. Affected file silc/client_ops.c.
6448 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6449 if the deleting was successful. Affected file silcd/idlist.[ch].
6451 * Added support for public key authentication in the connection
6452 authentication protocol in the client library. Affected file
6453 lib/silcclient/protocol.c.
6455 * Changed the server's silc_idlist_get_clients_by_* interface
6456 to support already allocated array so that new entries may be
6457 added to pre-allocated array. Affected file silcd/idlist.[ch].
6458 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6459 and command replies.
6461 * All command reply functions in the server now calls the
6462 pending command callback even if error occured. This way the
6463 error will be delivered to the client as well. Affected files
6464 silcd/command.c and silcd/command_reply.c.
6466 * Fixed INFO command to return local server's info if no server
6467 was provided. Affected file lib/silcclient/command.c.
6469 * Removed RESTART command for good. Updated the code and the
6472 * Rewrote parts of the task system. It is a bit simpler now.
6473 Removed unsued task priorities. The affected files are
6474 lib/silcutil/silctask.[ch].
6476 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6478 * Moved the USERS printing from the library to the application.
6479 Affected files lib/silcclient/command.c and silc/client_ops.c.
6481 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6485 * Added channel key re-key support. The re-key is perfomed
6486 only by the router and is done once in an hour. Added `rekey'
6487 field to the SilcChannelEntry in the server. Affected files
6488 silcd/server.c and silcd/idlist.h.
6490 * Added silc_task_unregister_by_context into the file
6491 lib/silcutil/silctask.[ch].
6493 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6495 * Added SILC_UMODE_GONE mode to indicate when the client is not
6496 present in the SILC network. Added also support to the local
6497 command AWAY that will set this mode. Added support of showing
6498 "xxx is gone" in WHOIS command. The USERS command shows the
6499 gone status as well.
6501 * Fixed setting server and router operator privileges in the
6502 server's UMODE command. Affected file silcd/command.c.
6504 * Merged the SKE KE1 and KE2 payloads into one payload. The
6505 new KE payload is equivalent to the old KE2 payload.
6507 Cleaned up the SKE Start Payload parsing. It now uses the
6508 simple buffer unformatting to do the parsing. A lot faster
6511 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6512 to the SKE that is used to indicate whether both of the SKE
6513 parties should perform authentication. By default only the
6514 responder performs authentication. By setting this flag also
6515 the initiator must do authentication. By default it is unset
6516 since in normal SKE case, client to server connection, only
6517 the responder should do authentication. When doing SKE between
6518 two clients both should perform authentication. Updated the
6519 code and the protocol specs.
6521 * A little fix to IDENTIFY command in the server. Search the
6522 client first by hash not nickname. Affected file is
6525 * Fixed the silc_client_close_connection to support closing
6526 the client to client connections wihtout deleting too much
6527 data. Affected file lib/silcclient/client.c.
6529 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6530 are received if protocol used to be active but is not anymore
6531 the application would crash due to NULL pointer dereference.
6532 Affected files silcd/server.c and lib/silcclient/client.c.
6534 * Added `hash' field to the SilcClientConnection to include
6535 the hash function negotiated in the SKE protocol.
6537 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6538 to set the channel founder authentication data. A client can
6539 claim the founder rights later by providing the authentication
6540 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6541 This way the channel founder can regain the channel founder
6542 privileges even it is left the channel. This works only on
6543 local server and the client must be connected to the same
6544 server to be able to regain the founder rights. Updated the
6545 protocol specs accordingly.
6547 Added support to the CMODE command in the client to set the
6548 founder auth data. Read the README to see how to set it.
6550 Added support to the CUMODE command to claim the founder
6551 rights. Read the README to see how to do it.
6553 Added support for the founder authentication to the Channel
6554 Entry in the server. Affected file silcd/idlist.h.
6556 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6557 server's CMODE command. Affected file silcd/command.c.
6559 * Added the following new functions into lib/silccore/silcauth.[ch]:
6560 silc_auth_get_method and silc_auth_get_data.
6562 * The server now saves the remote hosts public key to the
6563 SilcIDListData pointer. Affected file silcd/protocol.c.
6565 * The normal server now does not remove the channel entry from
6566 the cache if the founder authentication data is set. It used
6567 to remove it if the founder was the last one on the channel on
6568 the server and left the channel. The auth data is saved and
6569 if the channel is re-joined later the old entry is used with
6570 the old auth data. Affected files silcd/command_reply.c and
6573 * Removed the `pkcs' field from the SilcIDListData structure
6574 in the server; it is not used. Affected file silcd/idlist.h.
6576 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6578 * Fixed packet processing on slow links. Partial packets were
6579 never re-processed because the incoming data buffer was cleared
6580 by the application. Application must not directly clear the
6581 sock->inbuf, the packet processing routines handle it. Fixed
6582 this in client library and in server.
6584 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6586 * Fixed the WHOIS and IDENTIFY send reply function to really
6587 check whether to send list or just one entry. Affected file
6590 * Cleaned up the LEAVE command's channel key distribution. The
6591 affected file silcd/command.c.
6593 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6594 can enforce the channel mode as well. In that case the ID
6595 includes the ID of the server. The code now enforces the
6596 mode change if the router have different mode than the server.
6598 * The notify client operation with CMODE_CHANGE notify can now
6599 return NULL client_entry pointer if the CMODE was not changed
6600 by client. Application must check for this.
6602 * Added <Server ID> argument to INFO command to support server
6603 info fetching by Server ID.
6605 * Added silc_server_announce_get_channel_users to get assembled
6606 packets of channel users of the specified channel. Affected
6607 file silcd/server.[ch].
6609 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6610 was freed underneath the ID Cache.
6612 * Re-announce clients when the server received CHANNEL_CHANGE
6613 notify from the router. Affected file silcd/packet_send.c.
6615 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6617 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6618 crashed since it did not handle the fact that there is no cipher
6619 called "3" and didn't check the error condition. Now fixed.
6621 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6622 flag. It can be used to send message requests.
6624 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6626 * Implemented the RESTART command in the client.
6628 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6629 notice type messages. Added notice printing to the user
6632 * The channel keys are not re-generated if the channel's mode
6633 is PRIVKEY, ie private key on the channel exists. Affected
6634 files silcd/server.c and silcd/command.c.
6636 * Fixed a little bug in channel message delivery when channel
6637 private keys are set in the server. Affected file is
6638 silcd/packet_send.c.
6640 * Changed the setting on channel->on_channel = TRUE from the
6641 silc_client_save_channel_key to the JOIN command reply. The
6642 key payload is not received if the private channel key is set.
6643 Affected file lib/silcclient/command_reply.c and the
6644 lib/silcclient/client_channel.c.
6646 * When the CMODE_CHANGE notify is sent and the channel private
6647 key mode is removed the channel key must be re-generated in
6648 other cells as well. Added this support for the router in the
6649 silcd/packet_receive.c.
6651 * Added new local command NOTICE to send notice message on
6652 channel. Affected file silc/local_command.[ch].
6654 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6656 * Added new local command ME to the client. It is used to send
6657 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6658 some action. Affected file silc/local_command.[ch].
6660 * Changed channel_message and private_message client operations
6661 to deliver the message flags to the application. Added also
6662 the `flags' arguments to the silc_client_send_channel_message
6663 and silc_client_send_private_message functions. Affected file
6666 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6668 * Redefined the Private Message Payload to support private message
6669 keys and to support the new private message flags. Updated
6670 the protocol specs. Flags makes it possible to have for example
6671 CTCP style messages.
6673 * Added new type SilcPrivateMessagePayload and defined an API
6674 for it in the lib/silcclient/silcprivate.[ch].
6676 * Tested private message private keys successfully. Tested the
6677 private message key set, unset and list commands with the new
6680 * Redefined the Channel Message Payload to include the channel
6681 message flags (equal with private message flags) to support
6682 for example CTCP style messages.
6684 * Defined some of the message (for channel and private message)
6685 flags. Updated the protocol specs and added the flags to the
6686 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6688 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6690 * Added SilcKeyAgreementStatus type to the key agreement routines
6691 to indicate the current status and error if one occured.
6692 The status types are defined in the lib/silcclient/silcapi.h.
6694 * Added new local command KEY that is used to set and unset private
6695 keys for channels, set and unset private keys for private messages
6696 with remote clients and to send key agreement requests and
6697 negotiate the key agreement protocol with remote client. The
6698 key agreement is supported only to negotiate private message keys,
6699 it currently cannot be used to negotiate private keys for channels,
6700 as it is not convenient for that purpose.
6702 * Fixed a minor pending callback setting bug in the function
6703 silc_client_get_client_by_id_resolve, now the function works.
6704 Affected file lib/silcclient/idlist.c.
6706 * Added function silc_net_get_local_port to get local bound
6707 port by socket. Added to lib/silcutil/silcnet.[ch].
6709 * Added `sockets' and `sockets_count' fields to the SilcClient
6710 object. They hold the sockets of the listenning sockets in
6711 the client. Listenning sockets may be for example the key
6712 agreement server. Affected file lib/silcclient/client.[ch].
6713 Added functions the silc_client_add_socket and the
6714 silc_client_del_socket. They are exported to the application
6717 * Added ~./silc/clientkeys to support other client's public keys.
6719 * Renamed verify_server_key client operation to verify_public_key
6720 and added one argument to indicate the type of the connection
6721 (server, client etc.).
6723 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6725 * Added silc_server_connection_auth_request to handle the
6726 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6727 silcd/packet_receive.[ch].
6729 * Added silc_server_send_connection_auth_request into the
6730 silcd/packet_send.c to send the connection auth request packet.
6732 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6735 * Fixed the public key authentication in responder side in the
6736 server. The `auth_data' pointer includes the SilcPublicKey
6737 not the path to the public key. Affected file silcd/protocol.c.
6739 * Implemented the public key authentication in the initiator side
6740 in the server. Affected file silcd/protocol.c.
6742 * Removed the [RedirectClient] config section from the server
6743 configuration. Is not needed and I don't want to implement it.
6745 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6747 * Cleaned up the CMODE command in the server. It now works
6748 correctly and supports all the modes defined in the protocol.
6749 Affected file is silcd/command.c.
6751 * Added `hmac_name' field to the SilcChannelEntry in the server
6752 to hold the default HMAC of the channel. It can be set when
6753 creating the channel (with JOIN command). Affected files
6756 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6757 type to indicate the change of the current cipher and hmac
6758 on the channel. Client can safely ignore the <cipher> argument
6759 (if it chooses to do so) since the CHANNEL_KEY packet will
6760 force the channel key change anyway. The <hmac> argument is
6761 important since the client is responsible of setting the new
6762 HMAC and the hmac key into use.
6764 * Fixed the CMODE command in the client library as well.
6766 * Tested CMODE command in router environment successfully.
6768 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6770 * Show the version of the remote client (or server) when connecting
6771 to the server. It is logged to the log file. Affected file
6772 is silcd/protocol.c.
6774 * Fixed the KILLED notify handling in the client library. The
6775 client must be removed from all channels when receiving the
6778 Also, do not remove the client entry when giving the KILL
6779 command but when the KILLED notify is received.
6781 * Removed silc_idlist_find_client_by_nickname from the server.
6782 Not needed anymore. Affected files silcd/idlist.[ch].
6784 * Implemented the CHANNEL_CHANGE notify type handling to the
6785 server. Affected file silcd/server.c.
6789 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6791 * Added silc_server_send_notify_invite to send the INVITE
6792 notify between routers.
6794 * Implemented the INVITE command correctly to the server.
6796 * Implemented the INVITE notify type handling in the server.
6798 * Implemented the INVITE command to the client library and on the
6801 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6803 * Added function silc_server_get_client_resolve to find the
6804 client entry by ID from all ID lists and then resolve it
6805 (using WHOIS) if it cannot be found. Affected file is
6808 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6810 * Implemented the BAN command to the client library.
6812 * The JOIN command in the server now checks the invite list
6815 * Changed the silc_command_reply_payload_encode_va and the
6816 silc_command_payload_encode_va to support that if argument is
6817 NULL it ignores and checks the next argument. Affected file
6818 lib/silccore/silccommand.c.
6820 * Added silc_server_send_notify_ban to send the BAN notify
6821 type between routers.
6823 * Chaned the silc_notify_payload_encode to support that if
6824 argument is NULL it ignores and checks the next argument.
6825 Affected file lib/silccore/silcnotify.c.
6827 * Tested ban lists in router environment successfully.
6829 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6831 * Implemented BAN command to the server, in silcd/command.[ch].
6833 * Removed the BAN and INVITE_LIST modes from the CMODE command
6836 * Added function silc_string_match to regex match two strings.
6837 Affected files lib/silcutil/silcutil.[ch].
6839 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6841 * Redefined parts of the SilcChannelEntry in the server to support
6842 the new ban and invite lists.
6844 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6846 * Redefined the INVITE command. The same command can be used to
6847 invite individuals to the channel but also to manage the invite
6848 list of the channel (to add to and remove from the invite list).
6849 Updated the protocol specs.
6851 * Added new command SILC_COMMAND_BAN that can be used to manage
6852 the ban list of the channel. Updated the protocol specs.
6854 * Removed the channel modes: the SILC_CMODE_BAN and the
6855 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6856 in the CMODE command. The equivalent features are now available
6857 using INVITE and BAN commands. Updated the protocol specs.
6859 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6860 in the network about change in the current ban list. The notify
6861 type is not used by the client.
6863 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6864 support the invite lists.
6866 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6868 * Added new function silc_string_regexify that converts string
6869 including wildcard characters into regex string that can
6870 be used by the GNU regex library. Added into the file
6871 lib/silcutil/silcutil.[ch].
6873 Added silc_string_regex_combine to combine to regex strings
6874 into one so that they can be used as one regex string by
6875 the GNU regex library. Added into the file
6876 lib/silcutil/silcutil.[ch].
6878 Added silc_string_regex_match to match two strings. It returns
6879 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6881 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6883 * Imported GNU regex to the soruce tree into lib/contrib.
6884 Fixed some compiler warning from the regex.c.
6886 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6888 * Fixed MOTD command in the server to work in router environment.
6890 * Fixed the MOTD command in the client library to support
6891 the server argument in the command.
6893 * Added `nickname_len' argument to the silc_idlist_add_client
6894 in the server, as the `nickname' argument may be binary data
6897 * Added silc_idlist_get_channels to return all channels from
6900 * Implemented LIST command to the server. Affected file is
6903 * Implemented the LIST command to the client library and on the
6906 * Added [<user count>] argument to the LIST command reply.
6907 With private channels the user count is not shown.
6909 * Updated TODO and README.
6911 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6913 * The client entry's data.registered must be TRUE even with
6914 global client entry on global client list. The data.registered
6915 is used to check whether the client is anymore in the network,
6916 for example with WHOWAS command so it must be valid.
6918 * Fixed the WHOWAS command in the server. It now actually works
6919 in router environment. Added function into silcd/command_reply.c
6920 silc_server_command_reply_whowas_save.
6922 * Added silc_idlist_purge function to the silcd/idlist.c
6923 to periodically purge the ID Cache.
6925 * Fixed INFO command in the server. It works now in router
6926 environment. Added <server name> argument to the INFO command
6927 reply. Updated the protocol specs.
6929 * Fixed minor bug in silc_idcache_purge to not purge if the
6930 expire value is zero.
6932 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6933 they were buggy because of the WHOWAS information.
6935 * Fixed local command MSG to handle the async resolving of
6936 the remote client properly. It used to fail the first MSG.
6937 Affected file silc/local_command.c.
6939 * Added `data_len' field to SilcIDCache context.
6941 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6943 * Update TODO. Todo in commands in the server.
6945 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6947 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6948 used by routers as broadcast packet to inform other routers
6949 about the changed user mode.
6951 Implemented the notify handling in the server. Affected file is
6952 silcd/packet_receive.c. Added the function
6953 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6955 * Added new generic Channel Payload and deprecated the New Channel
6956 Payload. The New Channel Payload is now the generic Channel
6959 * Added new argument `mode' to the silc_server_send_new_channel
6960 as it is required in the Channel Payload now.
6962 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6963 and created a new and real SilChannelPayload to represent the
6964 new generic Channel Payload. Implemented the encode/decode
6965 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6967 * Added silc_server_get_client_channel_list to return the list
6968 of channels the client has joined for WHOIS command reply.
6969 Affected file silcd/server.[ch].
6971 * Implemented the channel list sending in the WHOIS command reply
6972 in server and in the client.
6974 Implemented the channel list displaying on the user interface
6975 as well. Affected file silc/client_ops.c.
6977 * Added silc_channel_payload_parse_list to parse list of Channel
6978 Payloads. It returns SilcDList list of SilcChannelPayloads.
6979 Client for example can use this function to parse the list of
6980 channels it receives in the WHOIS command reply. The caller
6981 must free the list by calling silc_channel_payload_list_free.
6982 Affected files lib/silccore/silcchannel.[ch].
6984 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6986 * Added one new argument <user mode> to the WHOIS command reply
6987 to return the mode of the user in SILC. Updated the protocol
6990 Implemented it to the server and client.
6992 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6994 * Fixed the mode printing on the user interface on joining.
6995 Affected file silc/client_ops.c.
6997 * Implemented the UMODE command and user modes in general to the
6998 client library and to the user interface.
7000 * Implemented the UMODE command to the server.
7002 * The server now sends UNKNOWN_COMMAND error status if client sends
7003 unknown command. Affected file silcd/command.c.
7005 * All server commands now handle the command identifier the right
7006 way when sending the command reply to the client. The client can
7007 use to identify the command replies with the identifier.
7009 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7011 * Added silc_server_get_client_route to resolve the route to
7012 the client indicated by the client ID. Affected file is
7015 * Added silc_server_relay_packet as general function to relay
7016 packet to arbitrary destination. This deprecates functions
7017 like _send_private_message_key, _relay_notify etc. Affected
7018 file is silcd/packet_send.[ch].
7020 Removed silc_server_send_key_agreement,
7021 silc_server_send_private_message_key and
7022 silc_server_packet_relay_notify functions from the file
7023 silcd/packet_send.[ch].
7027 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
7028 server. Affected file silcd/packet_receive.[ch].
7030 * Implemented the KILL command to the client. Implemented the
7031 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
7032 Affected files lib/silcclient/command[_reply].c and
7033 lib/silcclient/client_notify.c. Implemented the KILL notify
7034 printing in the user inteface.
7036 * Fixed a lot silc_parse_nick memory leaks from the client
7037 library in the file lib/silcclient/command.c.
7039 * Changed the silc_server_send_notify_on_channels's `sender'
7040 argument from SilcSocketConnection to SilcClientEntry to
7041 check the sender as entry and not as connection object and not
7042 to send to the client provided as argument. The affected file
7043 is silcd/packet_send.[ch].
7045 * The notify packets that are destined directly to the client used
7046 to not to be processed by the server. Now changed that and the
7047 server processes all notify packets. After relaying the packet
7048 to the client the notify packet is processed in the server.
7050 * The silc_server_free_client_data now checks whether there is
7051 pending outgoing traffic for the client and purges the data to
7052 the network before removing the client entry.
7054 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7056 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
7057 an client is killed from the SILC Network. Updated the protocol
7060 Added new function silc_server_send_notify_killed to the
7061 silcd/packet_send.[ch].
7063 * Added function silc_server_packet_relay_notify to relay notify
7064 packets that are destined directly to a client. In this case
7065 the server does not process the notify packets but merely relays
7066 it to the client. Affected file silcd/packet_send.[ch].
7068 Added also silc_server_packet_process_relay_notify to check
7069 whereto relay the notify. Affected file is
7070 silcd/packet_receive.[ch].
7072 * Implemented the KILL command to the server.
7076 * Added the backup schema desgined last fall to the protocol
7077 specs for everyone to see. The specification is in the
7078 *-spec-xx.txt draft and the packet type definitions for the
7079 backup routers is in *-pp-xx.txt draft. Thusly, added also
7080 new packet type SILC_PACKET_CELL_ROUTERS.
7082 * A big security problem in the implementation discovered. The
7083 signoff of an client did not cause new channel key generation
7084 which it of course should've done. The channel keys must be
7085 always re-generated when client leaves (or signoffs) the channel.
7086 The silc_server_remove_from_channels funtion now handles
7087 the channel key re-generation.
7089 * Added `sender' argument to the silc_server_send_notify_on_channels
7090 to not to send the client provided as argument. Affected file
7091 silcd/packet_send.[ch].
7093 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7095 * Implemented OPER and SILCOPER commands into the server and
7098 * Added silc_auth_verify and silc_auth_verify_data to verify
7099 the authentication directly from the authentication payload.
7100 It supports verifying both passphrase and public key based
7101 authentication. Affected file lib/silccore/silcauth.[ch].
7103 * Added `hash' field to the SilcIDListData structure. It is the
7104 hash negotiated in the SKE protocol. Affected file is
7107 * Slight redesigning of the SilcAuthPayload handling routines.
7108 Do not send SilcPKCS but SilcPublicKey as argument.
7110 * Implemented the public key authentication support to the
7111 serverconfig. The public key is loaded from the provided path
7112 and saved as authentication data to void * pointer. Thus,
7113 changed the unsigned char *auth_data to void *auth_data;
7115 * Fixed SHUTDOWN command to send the reply before the server
7116 is shutdown. :) Affected file silcd/command.c.
7118 * Fixed fatal bug in CONNECT command. The hostname was invalid
7119 memory and server crashed. Affected file silcd/command.c.
7121 * Fixed fatal bug in CLOSE command. The server_entry became
7122 invalid but was referenced later in the command. Affected file
7125 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7127 * Fixed fatal bug in failure packet handling. Server ignored
7128 the failure and thus crashed when it came.
7132 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7134 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
7135 that the command may be executed only once in (about) 2 seconds.
7136 The old SILC_CF_LAG flag is same but allows command bursts up
7137 to five before limiting.
7139 Added the support for CF_LAG and CF_LAG_STRICT flags to the
7140 server code. Various commands now includes the CF_LAG_STRICT
7141 flag to disallow any kind of miss-use of the command.
7143 * Fixed the silc_buffer_unformat to not to allocate any data
7144 if the length of the data is zero. It used to allocate the
7145 length + 1. Affected file lib/silcutil/silcbuffmt.c.
7147 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7149 * Changed the format of AdminConnection configuration section
7150 in the server. Added username of the admin to the format.
7151 Affected files silcd/serverconfig.[ch].
7153 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
7154 to return admin configuration data by host, username and/or
7157 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7159 * Implemented WHOWAS command to the server. Added the functions:
7161 silc_server_command_whowas_parse,
7162 silc_server_command_whowas_send_reply,
7163 silc_server_command_whowas_from_client and
7164 silc_server_command_whowas_from_server
7166 * Added <Client ID> argument to the WHOWAS command reply. Updated
7167 the protocol specs accordingly.
7169 * Implemented WHOWAS command and command_reply to the client
7172 Implemented the WHOWAS printing on the user interface.
7174 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7176 * Added new argument to the WHOWAS command reply, the real name.
7177 It is an optional argument. Updated the protocol specs.
7179 * Added SilcIDCacheDestructor callback that is registered when
7180 the SilcIDCache is allocated. The callback is called when
7181 an cache entry in the ID Cache expires, or is purged from the
7182 cache. Added into lib/silccore/idcache.[ch].
7184 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
7185 to destruct the client entries when the cache entry expires.
7186 Other ID Cache's in server and in the client library ignores
7189 * If the ID Cache entry's `expire' field is zero then the entry
7190 never expires. Added boolean `expire' argument to the
7191 silc_idcache_add function in the lib/silccore/idcache.[ch].
7192 If it is TRUE the default expiry value is used.
7194 * Added silc_server_free_client_data_timeout that is registered
7195 when client disconnects. By default for 5 minutes we preserve
7196 the client entry for history - for WHOWAS command.
7198 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7200 * Added support to the server to enforce that commands are not
7201 executed more than once in 2 seconds. If server receives
7202 commands from client more frequently, timeout is registered
7203 to process the commands. Affected file silcd/command.c.
7204 Added new function silc_server_command_process_timeout.
7206 * Changed NICK_NOTIFY handling in client library to check that
7207 if the client's nickname was changed, so there is no need to
7208 resolve anything from the server.
7210 * Removed error printing from the WHOIS and IDENTIFY commands.
7211 If error occurs then it is ignored silently in the client library.
7212 The application, however, may map the received error to
7213 human readable error string. The application currently maps
7214 the NO_SUCH_NICKNAME error to string.
7216 * Made the command status message public to the application. Moved
7217 them from lib/silcclient/command_reply.c to
7218 lib/silcclient/command_reply.h. The application can map the
7219 received command status to the string with the
7220 silc_client_command_status_message function.
7222 * Added check to the server to check that client's ID is same
7223 as the Source ID in the packet the client sent. They must
7226 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7228 * Added dist-bzip hook to the Makefile.am to make bzip2
7229 compressed distributions.
7231 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7233 * Server now enforces the maximum length for the nickname and
7234 the channel as protocol specification dictates. 128 bytes for
7235 nickname and 256 bytes for channel name.
7237 * Moved the WHOIS printing to the application. The client libary
7238 does not print out the WHOIS information anymore, the application
7239 must do it. Renamed silc_client_command_reply_whois_print to
7240 the silc_client_command_reply_whois_save.
7242 The client's idle time is also sent to the application now, and
7243 the idle is shown on screen.
7245 * Added silc_client_command_reply_identify_save to save the
7246 received IDENTIFY entries.
7248 * Do not check for channel private keys in message sending and
7249 reception if the channel does not have the PRIVKEY mode set.
7250 Affected file lib/silclient/client_channel.c.
7252 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7254 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
7255 just surfaced after chaning the JOIN procedure.
7257 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7259 * Added silc_client_get_clients_by_list to get client entries
7260 from Client ID list, that is returned for example by JOIN
7261 and USERS command replies. The application should use this
7262 function for example when JOIN command reply is received to
7263 resolve the clients already on the channel (library does not
7264 do that anymore as USERS command reply is not used in the JOIN
7265 procedure anymore). Affected files lib/silcclient/silcapi.h and
7266 lib/silcclient/idlist.c.
7268 * JOIN command reply and USERS command reply returns now SilcBuffer
7269 pointers instead of unsigned char pointers when returning
7270 the client list and mode list.
7272 * Added <Client ID> argument to the JOIN command reply, mainly
7273 for the server to identify for which client the command was
7274 originally sent. Updated protocol specs accordingly.
7276 * Added SilcDlist private_key pointer to the SilcChannelEntry
7277 in the client to support the channel private keys. Affected
7278 file is lib/silcclient/idlist.h.
7280 * Added SilcChannelPrivateKey argument to the function
7281 silc_client_send_channel_message so that application can choose
7282 to use specific private ke if it wants to. If it is not provided,
7283 the normal channel key is used, unless private keys are set.
7284 In this case the first (key that was added first) is used
7285 as the encryption key.
7287 * Implemented the support for channel private key handling.
7288 Implemented the following functions:
7290 silc_client_add_channel_private_key,
7291 silc_client_del_channel_private_keys,
7292 silc_client_del_channel_private_key,
7293 silc_client_list_channel_private_keys and
7294 silc_client_free_channel_private_keys
7296 Affected file lib/silcclient/client_channel.c.
7298 * Added the support for the private keys in the channel message
7299 sending and encryption and in the message reception and
7300 decryption. Affected funtions are
7301 silc_client_send_channel_message and silc_client_channel_message.
7303 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7305 * Added SKE's key verify callback to the client library's
7306 KE protocol context. Affected files lib/silcclient/protocol.[ch].
7308 * Removed the statement that server (or router) must send USERS
7309 command reply when joining to the channel so that the client
7310 knows who are on the channel. Instead, the client list and
7311 client's mode list is now sent in the JOIN command reply to the
7312 client who joined channel. This is better solution.
7314 * Added function silc_server_get_users_on_channel and function
7315 silc_server_save_users_on_channel to the silcd/server.[ch].
7317 * Removed function silc_server_command_send_users from the
7320 * Do not show topic on the client library anymore. The topic is
7321 sent in the command reply notify to the application and the
7322 application must show the topic now.
7324 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7326 * Added client searching by nickname hash into the IDENTIFY and
7327 WHOIS commands in the server as they were clearly missing from
7328 them. Affected file is silcd/command.c.
7330 * Fixed a bug in private message receiving in the client library.
7331 The remote ID was freed and it wasn't supposed, now it is
7334 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7336 * Minor fix to the channel payload; allocate the data area, as it
7337 needs to be of specific length.
7339 * If the key agreement port is zero then the operating
7340 system will define the bound port. Affected files are
7341 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7343 * Added new function silc_channel_payload_decrypt into the file
7344 lib/silccore/silcchannel.[ch].
7346 * Moved the channel message etc, check from silc_packet_decrypt
7347 to applications. The library calls now a generic
7348 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7349 when the packet is either normal or special. This was done to
7350 allow more wide range of checking that was not allowed when
7351 the code was in library. Now applications can do virtually any
7352 checks to the packet and return to the library the decision how
7353 the packet should be processed. Affected files are
7354 lib/silccore/silcpacket.[ch].
7356 Added silc_server_packet_decrypt_check to the server and
7357 silc_client_packet_decrypt_check to the client library.
7359 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7360 to send with specified source and destination information.
7362 * Channel message delivery between routers was broken after the
7363 channel key distribution was fixed earlier. The channel key
7364 was used be to distributed to other routers as well which is not
7365 allowed by the protocol. Now this is fixed and channel keys
7366 really are cell specific and the channel message delivery between
7367 routers comply with the protocol specification.
7369 * Fixed various commands in server to check also the global list
7370 for the channel entry and not just the local list. The affected
7371 file silcd/command.c.
7373 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7375 * Added assert()s to buffer formatting and unformatting routines
7376 to assert (if --enable-debug) when error occurs. Affected
7377 file: lib/silcutil/silcbuffmt.c.
7379 * Changed to auto-reconnect to check whether the remote host is
7380 router and register the re-connect timeout if it is. It used
7381 to check that whether we are normal server, but router must do
7382 auto-reconnect with another router as well. Affected file
7385 * Removed the [<key len>] option from CMODE command as the cipher
7386 name decides the key length, nowadays. See the defined ciphers
7387 from the protocol specification.
7389 * Added [<hmac>] option to the CMODE command to define the HMAC
7390 for the channel. Added SILC_CMODE_HMAC channel mode.
7392 * Added [<hmac>] option for the JOIN command so that user can
7393 select which HMAC is used to compute the MACs of the channel
7396 * Added Hmac field to the Channel Message Payload. The integrity
7397 of plaintext channel messages are now protected by computing
7398 MAC of the message and attaching the MAC to the payload. The
7399 MAC is encrypted. Now, it is clear that this causes some
7400 overhead to the size of the packet but rationale for this is that
7401 now the receiver can verify whether the channel message decrypted
7402 correctly and also when private keys are set for the channel the
7403 receiver can decrypt the packet with several keys and check from
7404 the MAC which key decrypted the message correctly.
7406 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7407 lib/silccrypt/silccipher.[ch].
7409 * Added silc_hash_len to return the digest length into the
7410 lib/silcrypt/silchash.[ch].
7412 * Rewrote parts of Silc Channel Payload interface in the
7413 lib/silccore/silcchannel.[ch]. The encode function now also
7414 encrypts the packet and parse function decrypts it.
7416 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7418 * Fixed a minor formatting bug in the SKE's key material processing.
7419 It actually might have processed the keys wrong way resulting
7422 * Redefined the mandatory HMAC algorithms and added new algorithms.
7423 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7424 and hmac-md5 truncated to 96 bits. The mandatory is now
7425 hmac-sha1-96. Rest are optional (including the one that used
7426 to be mandatory). Rationale for this is that the truncated HMAC
7427 length is sufficient from security point of view and can actually
7428 make the attack against the HMAC harder. Also, the truncated
7429 HMAC causes less overhead to the packets. See the RFC2104 for
7432 * Added new [hmac] configuration section. The SKE used to use
7433 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7434 is of course wrong. The official names that must be proposed in
7435 the SKE are the ones defined in the protocol specification
7436 (hmac-sha1-96 for example). The user can configure any hmac
7437 using any hash function configured in the [hash] section. At
7438 least, the mandatory must be configured.
7440 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7442 * Added HMAC list to the SKE proposal list. It has now both
7443 hash algorithm list and HMAC list. This makes the protocol
7444 incompatible with previous versions. The SKE now seems to work
7445 the way it is supposed to work, for the first time actually.
7447 * Defined plain Hash algorithms to the protocol specification.
7450 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7452 * Implemented support for key agreement packets into the server.
7453 Added functions silc_server_key_agreement and
7454 silc_server_send_key_agreement. Other than these functions,
7455 server has nothing to do with this packet.
7457 * Added support for private message key packets into the server.
7458 Added functions silc_server_private_message_key and
7459 silc_server_send_private_message_key.
7463 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7464 called in the protocol's final callback instead in the END
7465 protocol state. This makes a little more sense and in the same
7466 time in client we can use the same protocol routines for normal
7467 key exchange and to key agreement packet handling as well.
7469 * Added to both client's and server's KE protocol context the
7470 SilcSKEKeyMaterial pointer to save the key material. We will
7471 bring the key material to the protocol's final callback by doing
7472 this. The final callback must free the key material.
7474 * Added SKE's packet_send callback into client's KE protocol
7475 context so that the caller can choose what packet sending function
7476 is used. This way we can use different packet sending when
7477 doing normal SKE when doing key agreement packet handling (in
7478 the key agreement packet handling we do not want to encrypt
7481 * Implemented the responder side of the key agreement routines
7482 in the client. The client can now bind to specified port and
7483 accept incoming key negotiation. The key material is passed
7484 to the application after the protocol is over.
7486 * Implemented the processing of incoming Key Agreement packet
7487 in the client. Added function silc_client_key_agreement to
7490 * Implemented the intiator side of the key agreement routines
7491 in the client. The client can now initiate key agreement with
7492 another remote client. The key material is passed to the
7493 application after the protocol is over.
7495 * Created client_keyagr.c to include all the key agreement
7498 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7499 SILC_TASK_CALLBACK except that it is not static.
7501 * Created client_notify.c and moved the Notify packet handling
7502 from the client.[ch] into that file.
7504 * Created client_prvmsg.c and moved all private message and
7505 private message key routines from the client.[ch] into that file.
7507 * Create client_channel.c and moved all channel message and
7508 channel private key routines from the client.[ch] into that file.
7510 * Changed silc_client_get_client_by_id_resolve to resolve with
7511 WHOIS command instead of IDENTIFY command, in the file
7512 lib/silclient/idlist.c.
7514 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7516 * Implemented the SKE's responder side to the Client library.
7518 * When FAILURE is received to the protocol do not trust it
7519 blindly. Register a timeout to wait whether the remote closes
7520 the connection as it should do it, only after that process the
7521 actual failure. This was changed to both client and server.
7523 * Added client_internal.h to include some of the structures
7524 there instead of client.h in lib/silcclient/.
7526 * Added function silc_task_unregister_by_callback to unregister
7527 timeouts by the callback function.
7529 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7531 * Some "Incomplete WHOIS info" errors has been appearing on the
7532 log files. Took away the entry->userinfo check from WHOIS
7533 reply sending. The entry->userinfo is now " " if client did not
7534 provide one. I thought this was fixed earlier but something
7535 is wrong still. Let's see if the error still appears.
7537 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7539 * Fixed a minor bug in the login when the channel key is
7540 re-generated in the server. It used to generate the key in
7541 wrong order and thus caused problems in the channel traffic.
7543 * Fixed a minor bug in channel key distsribution after
7544 KICK command. The key was not sent to the router even though
7547 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7549 * Added silc_ske_process_key_material_data as generic routine
7550 to process any key material as the SILC protocol dictates. The
7551 function is used by the actual SKE library but can be used by
7552 applications as well. This relates to the private message keys
7553 and the channel private keys since they must be processed the
7554 same way the normal SILC session keys. The protocol dictates
7555 this. Affected files: lib/silcske/silcske.[ch].
7557 Added also silc_ske_free_key_material to free the
7558 SilcSKEKeyMaterial structure.
7560 * Defined silc_cipher_set_key function to set the key for
7561 cipher without using the object's method function. The affected
7562 files: lib/silccrypt/silccipher.[ch].
7564 * Implemented silc silc_client_add_private_message_key,
7565 silc_client_add_private_message_key_ske,
7566 silc_client_del_private_message_key,
7567 silc_client_list_private_message_keys and
7568 silc_client_free_private_message_keys functions in the
7571 Added functions silc_client_send_private_message_key to send
7572 the Private Message Key payload and silc_client_private_message_key
7573 to handle incoming Private Message Key payload.
7575 * Added Cipher field to the Private Message Key payload to set
7576 the cipher to be used. If ignored, the default cipher defined
7577 in the SILC protocol (aes-256-cbc) is used.
7579 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7581 * Removed lib/silcclient/ops.h file.
7583 Redefined parts of the SILC Client Library API. Created new
7584 file silcapi.h that deprecates the ops.h file and defines the
7585 published Client Library API. Defined also private message key
7586 API and channel private key API into the file.
7588 This is the file that the application must include from the
7589 SILC Client Library. Other files need not be included by
7590 the application anymore.
7592 * Added new key_agreement client operation callback and also
7593 defined the Key Agreement library API for the application.
7595 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7597 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7598 is used by clients to request key negotiation between another
7599 client in the SILC network. If the negotiation is started it
7600 is performed using the SKE protocol. The result of the
7601 negotiation, the secret key material, can be used for example
7602 as private message key.
7604 Implemented the Key Agreement payload into the files
7605 lib/silccore/silauth.[ch].
7607 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7609 * Redefined ciphers for the SILC protocol. Added some new ciphers
7610 and defined the key lengths for the algorithms. Changed the
7611 code accordingly. The default key length is now 256 bits.
7613 * Fixed SKE key distribution function silc_ske_process_key_material
7614 when the key length is more than 128 bits. The default key
7615 length in SILC is now 256 bits.
7617 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7618 to indicate unsupported algorithm.
7620 * Renamed rijndael.c to aes.c and all functions as well.
7622 * Fixed a long standing channel key setting bug in client library.
7623 Weird that it has never surfaced before.
7625 * Fixed bug in channel deletion. If the entire channel is removed
7626 then it must also delete the references of the channel entry
7627 from the client's channel list as the client's channel entry and
7628 the channel's client entry share same memory.
7630 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7632 * Implemented CONNECT and SHUTDOWN commands in the client.
7634 * Implemented CLOSE command to the client.
7636 * Added the function silc_idlist_find_server_by_name into the
7637 files silcd/idlist.[ch].
7639 Added the function silc_idlist_find_server_by_conn into the
7640 files silcd/idlist.[ch].
7642 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7644 * DIE command was renamed to SHUTDOWN. Updated the both code
7647 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7648 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7650 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7653 * Added function silc_server_create_connection function to create
7654 connection to remote router. My server implementation actually
7655 does not allow router to connect to normal server (it expects
7656 that normal server always initiates the connection to the router)
7657 so the CONNECT command is only good for connecting to another
7660 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7662 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7663 or some other client was kicked from the channel.
7665 Implemented the handling of the notify type to both client
7668 Implemented silc_server_send_notify_kicked to send the KICKED
7669 notify. It is used to send it to the server's primary router.
7671 * Implemented the KICK command into server and client.
7673 * Added `query' argument to the silc_idlist_get_client function
7674 to indicate whether to query the client from server or not if
7677 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7678 to indicate that the client is not channel founder.
7682 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7684 * Removed the rng context from SilcPacketContext structure and
7685 changed that the packet routine uses the Global RNG API.
7687 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7689 * Added support for quit message that client can "leave" on the
7690 channel when it quits the SILC. It is ditributed inside the
7691 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7693 Added silc_server_free_client_data that will take the
7694 signoff message as argument.
7696 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7698 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7700 * Updated parts of the protocol specification to keep it up
7703 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7705 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7706 payloads in one packet.
7708 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7709 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7710 use now the new List flag.
7712 * Also deprecated the following packet types: REPLACE_ID,
7713 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7715 * Added list support for Notify packet in server.
7717 * Added silc_server_send_notify_channel_change to send the
7718 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7719 the silc_server_send_replace_id.
7721 * Added silc_server_send_notify_nick_change to send the
7722 NICK_CHANGE notify type. Deprecates the function
7723 silc_server_send_replace_id.
7725 * Added silc_server_send_notify_join to send the JOIN notify type.
7726 Deprecates the function silc_server_send_new_channel_user.
7728 * Added silc_server_send_notify_leave to send LEAVE notify type.
7729 Deprecates the function silc_server_send_remove_channel_user.
7731 * Added silc_server_send_notify_cmode and
7732 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7733 types. Deprecates the silc_server_send_set_mode function.
7735 * Added SERVER_SIGNOFF notify type to indicate that server has
7736 quit. This means that all clients on the channel from that
7737 server will drop. This can be also used when netsplit happens.
7739 Deprecated REMOVE_ID packet type since it is not needed anymore
7742 Added silc_server_send_notify_server_signoff to send the
7743 SERVER_SIGNOFF notify type. Deprecates the function
7744 silc_server_send_remove_id.
7746 Added also silc_server_send_notify_signoff to send the
7747 SIGNOFF notify type.
7749 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7750 SILC protocol from this day on. Changed the protocol
7751 specification as well.
7753 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7754 notify type. It is used between routers to notify about
7755 topic changes on a channel.
7757 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7760 * Partly updated the protocol specification to comply with the
7761 changes now made. It is still though a bit outdated.
7763 * The JOIN notify type now takes one extra argument <Channel ID>.
7764 The packet used to be destined to the channel but now the
7765 JOIN type may be sent as list thus it is impossible to
7766 destine it to any specific channel. By adding this argument
7767 it is again possible.
7769 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7771 * Added CREDITS file. The CHANGES and CREDITS file will appear
7772 in the distribution as well.
7774 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7776 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7777 types in the server's silcd/packet_receive.c.
7779 * Implemented CMODE and CUMODE to work in router environment.
7781 * Fixed minor encoding and decoding buglet from the
7782 lib/silccore/silcmode.c.
7784 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7787 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7789 * Changed all SilcConfigServer* and silc_config_server* to
7790 SilcServerConfig* and silc_server_config*, respectively.
7793 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7795 * Associated the ID (client or server ID) to the Authentication
7796 Payload to avoid any possibility of forging. Updated the
7797 protocol specification and the code accordingly.
7799 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7801 * The RSA key length is now save to the RsaKey context in the
7802 key generation process in lib/silccrypt/rsa.c. The key length
7803 is now used to figure out the maximum size of the block allowed
7804 to be encrypted/signed.
7806 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7807 is equivalent to the silc_mp_mp2bin but does not allocate any
7810 * Changed silc_mp_mp2bin API to take length argument. If it is
7811 non-zero then the buffer is allocated that large. If zero, then
7812 the size is approximated using silc_mp_sizeinbase, which however
7815 * Created Global RNG API which is global RNG that application can
7816 initialize. After initializing, any routine anywhere in the
7817 code (including library) can use RNG without allocating a new
7818 RNG object. This was done to allow this sort of use of the
7819 RNG in code that has no chance to allocate RNG object. All
7820 applications currently allocate this and many routines in the
7821 library use this. Affected file lib/silccrypt/silcrng.[ch].
7823 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7824 it to use the Global RNG API.
7826 * Defined Authentication Payload into protocol specification that
7827 is used during SILC session to authenticate entities. It is
7828 used for example by client to authenticate itself to the server
7829 to obtain server operator privileges.
7831 Implemented this payload into the lib/silccore/silcauth.[ch].
7832 Implemented also routines for public key based authentication
7833 as the new protocol specification dictates.
7835 Moved definitions of different authentication methods from
7836 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7838 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7839 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7840 silc_pkcs_verify_with_hash functions into the file
7841 lib/silccrypt/silcpkcs.[ch].
7843 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7845 * The client entry's userinfo pointer must be always valid.
7846 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7847 will fail since it requires the userinfo. Now, the userinfo
7848 is allocated as "" if actual userinfo does not exist. Actually,
7849 it must exist and it is totally Ok to drop client connections
7850 that does not announce the userinfo. However, we will make
7851 this workaround for now.
7853 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7854 to return the remote port by socket.
7856 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7858 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7859 SILC_SERVER_PENDING_EXEC and added an new macro
7860 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7861 data or when error occurs while processing the pending command.
7863 Added new argument `destructor' into silc_server_command_pending
7864 and to the SilcServerCommandPending object. This destructor is
7865 now called after calling the pending callback or if error occurs
7866 immediately. If error occurs the actual pending callback won't
7867 be called at all - only the destructor. The destructor may be
7868 NULL if destructor is not needed.
7870 All this applies for client library code as well. Similar
7871 changes were made there as well for the pending commands.
7873 In the client, the application must now allocate the
7874 SilcClientCommandContext with the silc_client_command_alloc
7877 * Added reference counter to the SilcServerCommandContext. Added
7878 function silc_server_command_alloc and silc_server_command_dup
7881 Same type of functions added to the client library for the same
7884 * Removed the cmd_ident from IDListData away since it is now
7885 global for all connections. It is the command identifier used
7886 in command sending and with pending commands. The affected file
7889 * Added reference counter to the SilcSocketConnection objecet to
7890 indicate the usage count of the object. The object won't be
7891 freed untill the reference counter hits zero. Currently only
7892 server uses this, and client ignores it. The client must be
7893 set to use this too later. The affected files are
7894 lib/silccore/silcsockconn.[ch]. Added also the function
7895 silc_socket_dup to increase the reference counter.
7897 This was mainly added because it is possible that the socket
7898 is removed underneath of pending command or other async
7899 operation. Now it won't be free'd and proper DISCONNECTING
7900 flags, etc. can be set to avoid sending data to connection that
7901 is not valid anymore.
7903 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7904 the connection. After that it sets SILC_SET_DISCONNECTED.
7905 It is, however, possible that the socket data is not still freed.
7906 The silc_server_packet_process now checks that data is not
7907 read or written to connection that is DISCONNECTED. The socket
7908 get's freed when the reference counter hits zero.
7910 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7912 * Changed the client operation API: channel_message operation's
7913 `sender' is now the client entry of the sender, not the nickname
7914 and the `channel' is the channel entry, not the channel name.
7916 In the private_message operation the `sender' is now also the
7917 client entry of the sender not the nickname.
7919 Affected file is lib/silcclient/ops.h and all applications
7920 using the client operations.
7922 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7924 * Moved the calling of ops->connect() from connect_to_server_final
7925 into receive_new_id functin since that is the point when the
7926 client is actually allowed to send traffic to network. The
7927 affected file is lib/silcclient/client.c.
7929 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7931 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7932 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7933 (if needs broadcasting) instead of broadcasting the packets one
7934 by one which would make a burst in the network traffic.
7936 * Added `broadcast' argument to the functions in silcd/server.[ch]
7937 silc_server_create_new_channel[_with_id] to indicate whether
7938 to send New Channel packet to primary router.
7940 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7942 * Added new function into the silcd/server.[ch] files:
7943 silc_server_create_new_channel_with_id to create new channel with
7944 already existing Channel ID.
7946 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7947 lib/silccore/silcpacket.h. This packet is used t send list of
7948 Set Mode payloads inside one packet. Server uses this to set
7949 the modes for the channels and clients on those channels, that it
7950 announced to the router when it connected to it. The protocol
7951 specification has been updated accordingly.
7953 * The silc_server_new_channel did not handle the packet coming
7954 from normal server as it normally does not send that. However,
7955 when it announces its channels it does send it. Implemented
7956 the support for that.
7958 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7959 into the file lib/silccore/id.h.
7961 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7963 * Fixed memory leaks in the functions silc_idlist_del_client,
7964 silc_idlist_del_channel and silc_idlist_del_server in the file
7965 silcd/idlist.c. All of those leaked like a sieve.
7967 * Fixed some small memory leaks in the client's function
7968 silc_client_notify_by_server.
7970 * Added functions into silcd/server.c: silc_server_announce_clients,
7971 silc_server_announce_channels and silc_server_announce_server.
7972 These functions are used by normal and router server to announce
7973 to its primary router about clients, channels and servers (when
7974 router) that we own. This is done after we've connected to the
7977 These functions effectively implements the following packet types:
7978 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7979 and SILC_PACKET_NEW_ID_LIST.
7981 * Added new functions into the silcd/packet_receive.[ch]:
7982 silc_server_new_id_list, silc_server_new_channel_list and
7983 silc_server_new_channel_user_list to handle the incoming
7984 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7986 * Added support of changing Channel ID in the function
7987 silc_server_replace_id. If the server that announces a channel
7988 to the router already exists in the router (with same name but
7989 with different Channel ID), router is responsible to send
7990 Replace ID packet to the server and force the server to change
7991 the Channel ID to the one router has.
7993 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7994 client that the Channel ID has been changed by the router. The
7995 normal server sends this to the client. Client must start using
7996 the new Channel ID as the channel's ID.
7998 Implemented handling of this new type into lib/silcclient/client.c
7999 into the function silc_client_notify_by_server.
8001 * Added new function silc_idlist_replace_channel_id into the files
8002 silcd/idlist.[ch] to replace the Channel ID.
8004 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8006 * Call silc_server_command_identify_check always when processing
8007 the IDENTIFY command in silcd/command.c
8009 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8011 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
8012 send keepalive packets. The packet can be sent by clients,
8013 servers and routers.
8015 Added function silc_socket_set_heartbeat into the file
8016 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
8017 If not set, the heartbeat is not performed. The actual
8018 heartbeat is implemented in the low level socket connection
8019 library. However, application is responsible of actually
8022 Added silc_server_send_heartbeat to send the actual heartbeat
8023 packet into silcd/packet_send.[ch]. Server now performs
8024 keepalive with all connections.
8026 * Added silc_task_get_first function into lib/silcutil/silctask.c
8027 to return the timeout task with shortest timeout. There was a bug
8028 in task unregistration that caused problems. TODO has been
8029 updated to include that task system must be rewritten.
8031 * The client library will now resolve the client information when
8032 receiving JOIN notify from server for client that we know but
8033 have incomplete information.
8035 * Rewrote parts of silc_server_remove_from_channels and
8036 silc_server_remove_from_one_channel as they did not remove the
8037 channel in some circumstances even though they should've.
8039 * Encryption problem encountered in server:
8041 The LEAVE command used to send the Channel Key packet to the
8042 router immediately after generating it. However, the code
8043 had earlier sent Remove Channel user packet but not immediately,
8044 ie. it was put to queue. The order of packets in the router
8045 was that Channel Key packet was first and Remove Channel User
8046 packet was second, even though they were encrypted in the
8047 reverse order. For this reason, MAC check failed. Now, this
8048 is fixed by not sending the Channel Key packet immediately but
8049 putting it to queue. However, this is more fundamental problem:
8050 packets that are in queue should actually not be encrypted
8051 because packets that are sent immediately gets encrypted
8052 actually with wrong IV (and thus MAC check fails). So, packets
8053 that are in queue should be encrypted when they are sent to
8054 the wire and not when they put to the queue.
8056 However, the problem is that the current system has not been
8057 designed to work that way. Instead, the packet is encrypted
8058 as soon as possible and left to the queue. The queue is then
8059 just purged into wire. There won't be any fixes for this
8060 any time soon. So, the current semantic for packet sending
8063 o If you send packet to remote host and do not force the send
8064 (the packet will be in queue) then all subsequent packets to the
8065 same remote host must also be put to the queue. Only after the
8066 queue has been purged is it safe again to force the packet
8069 o If you send all packets immediately then it safe to send
8070 any of subsequent packets through the queue, however, after
8071 the first packet is put to queue then any subsequent packets
8072 must also be put to the queue.
8074 Follow these rules and everything works fine.
8076 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8078 * Added new function silc_server_remove_clients_by_server to
8079 remove all client entries from ID list when the server connection
8080 is lost. In this case it is also important to invalidate all
8081 client entires as they hold the invalid server entry. This
8082 fixes fatal bug when server has lost connection and will reconnect
8085 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8087 * Made some sanity checks to silc_server_daemonise like to check
8088 whether the requested user and group actually exists.
8090 * Added sanity check to SKE's silc_ske_responder_finish to check
8091 that the public and private key actually is valid.
8093 * Invalidate the client's nickname when receiving Replace ID
8094 packet and the Client ID is being replaced. This means that the
8095 server will query the nickname if someone needs it (client)
8098 * Sort the ID Cache in client library when the ID Cache data
8099 has changed (needs sorting).
8101 * Do not allow for SILC client to create several connections to
8102 several servers. The client does not support windows right now
8103 and generating multiple connections causes weird behaviour.
8105 Irssi-silc client does support windows and can handle several
8106 connections without problems, see: www.irssi.org and SILC plugin.
8108 * Fixed some places where client was added to the IDList. The
8109 rule of thumb is following (in order to get everything right):
8110 If the client is directly connected local client then the
8111 `connection' argument must be set and `router' argument must be
8112 NULL to silc_idlist_add_client function. If the client is not
8113 directly connected client then the `router' argument must
8114 bet set and the `connection' argument must be NULL to the
8115 silc_idlist_add_client function.
8117 * The funtion silc_server_packet_send_local_channel actually did
8118 not check whether the client was locally connected or not. It
8119 does that now. Fixed a bug related to LEAVE command.
8121 * Fixed Remove Channel User payload parsing bug in server's
8122 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
8124 * The server's silc_server_save_channel_key now checks also the
8125 global ID list for the channel as it might not be in the local
8126 list. Fixed a bug related to LEAVE command.
8128 * Is this the end of the [<unknown>] buglet that has been lurking
8129 around for a long time? A little for loop fix in server's
8130 silc_server_command_whois_parse that is used by both IDENTIFY
8131 and WHOIS command. At least, this was a clear bug and a cause
8132 of one type of [<unknown>] buglet.
8134 * WHOIS and IDENTIFY commands call the function
8135 silc_server_command_[whois/identify]_check function even if
8136 we are not router server.
8138 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8140 * Added --with-gmp configuration option. If set the GMP
8141 is always compiled in the SILC source tree. If not set then
8142 it is checked whether the system has the GMP3 installed. If
8143 it has then the GMP won't be compiled (the system's headers
8144 and library is used), if it doesn't have it then the GMP is
8145 compiled in the SILC source tree.
8147 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8149 * Changed RSA private exponent generation to what PKCS #1
8150 suggests. We try to find the smallest possible d by doing
8151 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
8152 not security fix but optimization.
8154 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8156 * Added new config entry [Identity] to fork the server and run
8157 it as specific user and group. A patch from Bostik.
8159 * Imported Dotconf configuration library into lib/dotconf.
8160 This will be used to create the SILC configuration files later.
8161 It will appear in the distsribution after this commit.
8163 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8165 * A big code auditing weekend happening. Auditing code for
8166 obvious mistakes, bugs and errors. Also, removing any code
8169 Removed files for being obsolete:
8171 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
8172 inline in the file lib/silcutil/silcbuffer.h)
8174 o lib/silcutil/silcbufutil.c (the header has inline versions)
8176 Changed code to fix possible error conditions:
8178 o The buffer formatting routines now check that the destination
8179 buffer really has enough space to add the data. This applies for
8180 both buffer formatting and unformatting
8181 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
8182 unformatting was changed to accomodate following rules:
8183 XXX_*STRING_ALLOC will allocate space for the data into the pointer
8184 sent to the function while XXX_*STRING will not allocate or copy
8185 the data into the buffer. Instead it sets the pointer from the
8186 buffer into the pointer sent as argument (XXX_*STRING used to
8187 require that the pointer must be allocated already). This change
8188 makes this whole thing a bit more consistent and more optimized
8189 (note that the data returned in the unformatting with XXX_*STRING
8190 must not be freed now). The routines return now -1 on error.
8192 o Tried to find all code that use buffer_format and buffer_unformat
8193 and added return value checking to prevent formatting and
8194 especially unformatting errors and possible subsequent fatal
8197 o Changed ske->x and ske->KEY to mallocated pointers in
8198 lib/silcske/silcske.h. Fixed possible data and memory leak.
8200 o Added return value checking to all *_parse* functions. Fixed
8201 many memory leaks as well.
8203 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
8204 so that buffer overflows would not happen. All code now also
8205 checks the return value as it can fail.
8207 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8209 * Added reconnection support to server if the normal server looses
8210 its connection to the router (for example if router is rebooted).
8211 The server performs normal reconnection strategy implemented
8212 to the server. Affected file silcd/server.c.
8214 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8216 * Added new packet type SILC_PACKET_SET_MODE that is used to
8217 distribute the information about changed modes (for clients,
8218 channels and clients channel modes) to all routers in the
8219 network. Updated the protocol specification accordingly.
8221 Added functions into silcd/packet_send.c and
8222 silcd/packet_receive.c: silc_server_send_set_mode,
8223 silc_server_set_mode.
8225 Added new files silcmode.[ch] into lib/silccore that implements
8226 the encoding and decoding of Set Mode Payload. Added new type
8227 SilcSetModePayload. Moved the definitions of different modes
8228 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
8230 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8232 * Oops, a little mistake in server's connection authentication
8233 protocol. The protocol is not ended with FAILURE but with
8234 SUCCESS if the authentication is Ok. :) Affected file is
8237 * Implemented NICK_CHANGE notify handling in server in the file
8238 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
8239 the local clients on the channel. After the changing nickname
8240 in router environment snhould work and the [<unknown>] nickname
8241 should appear no more.
8243 The silc_server_replace_id function that receives the Replace ID
8244 payload now sends the NICK_CHANGE notify type also in the file
8245 silcd/packet_receive.c
8247 * Changed WHOIS and IDENTIFY command to support the maximum amount
8248 of arguments defined in protocol specs (3328 arguments). This
8249 fixed a bug that caused problems when there were more than three
8252 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8254 * Added extra parameter, command identifier, to the
8255 silc_client_send_command so that explicit command identifier
8258 Changed that ID list routines uses specific command identifier
8259 when sending WHOIS/IDENTIFY requests to the server so that they
8260 can be identified when the reply comes back.
8262 Affected files lib/silcclient/command.[ch],
8263 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
8265 * Added `sender' argument to silc_server_packet_send_to_channel
8266 to indicaet the sender who originally sent the packet to us
8267 that we are now re-sending. Ignored if NULL. Affected file
8268 silcd/packet_send.[ch].
8270 * Added some server statistics support in silcd/server_internal.h
8271 SilcServerStatistics structure and around the server code. Also
8272 send some nice statistics information when client is connecting
8275 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8277 * Fixed channel ID decoding in server's JOIN command reply in
8278 silcd/command_reply.c
8280 * Fixed braodcasting of replace ID payload to not to send it if
8281 we are standalone server in silcd/packet_receive.c.
8283 * Fixed all channel message sending routines to not to send
8284 packets to clients that has router set, since they are routed
8285 separately in the same function earlier. Affects file
8286 silcd/packet_send.c and all channel packet sending functions.
8288 * In USERS reply, res_argv[i] are not allocated, the table
8289 is allocated. Thus changed that free the table, not its
8292 * In server's whois_check and identify_check if the client is
8293 locally connected do not send any WHOIS commands - they are not
8296 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8298 * Fixed some minor bugs in client when sending WHOIS command. The
8299 arguments was in wrong order.
8301 * Removed statis function add_to_channel from server in
8302 silcd/command.c that was previously used with the joining but
8305 * Tested USERS command in router environment successfully with two
8306 routers, two servers and two clients.
8308 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8310 * Reorganized the USERS command and command reply in client library
8311 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
8312 When the command is given by user we register a pending command
8313 callback that will reprocess the command after the reply has been
8314 received from the server. When reprocessing the packet we then
8315 display the information. Thus, the USERS information is displayed
8316 now in the command callback instead of in the command reply
8317 callback. The processing of the command is same as previously
8318 when server has sent the command reply in the JOINing process.
8320 * Added to USERS command in silcd/command_reply.c to join the client,
8321 we didn't use to know about, to the channel after we've created
8322 a client entry for it. Also, for clienet we did know already still
8323 check whether it is on the channel or not and add it if not.
8325 * Removed silc_server_command_join_notify as the function and its
8328 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8330 * Changed the client's pending command handling to the same as the
8331 server's pending command handling. It is also now possible to
8332 execute command reply functions from other command reply
8333 function as the function callbacks for commands and command
8334 replies are one and same. The pending commands are not static
8335 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8336 in client connection context. Thus, pending commands are server
8337 connection specific as it is convenient.
8339 Changed the function silc_client_command_pending and
8340 silc_client_command_pending_del and added new function
8341 silc_client_command_pending_check. Removed the
8342 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8345 * Added cmd_ident, current command identifier, to the client
8346 connection context in lib/silcclient/client.h to keep track on
8347 command identifiers used in command sending. Client's command reply
8348 function handling now supports the mandatory command identifiers.
8350 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8351 funtions in client to fully support pending command callbacks.
8353 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8354 as one of the arguments to the application in the command reply
8357 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8358 before first releasing SILC but came back. Now it is removed again
8359 and should come back nomore. The FORWARDED flag was used only
8360 by the JOINing procedure by forwarding the command packet to router.
8361 Now, the JOINing procedure has been changed to more generic (due
8362 to various router environment issues) and FORWARDED is not needed
8363 anymore for anything. The protocol specification is yet to be
8366 Now, removed silc_server_packet_forward from server and the flag
8367 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8369 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8371 * Renamed NAMES command to USERS command. The NAMES was named that
8372 due to historical reasons. Now it is renamed. Also, rewrote
8373 parts of the USERS command. The nickname list is not sent anymore
8374 by the server. Only Client ID and mode lists are sent in the USERS
8375 command. Changed this also to the protocol specification.
8377 The client now resolves the names and stuff after it receives
8378 the USERS list from the server when joining to the channel.
8380 * WHOIS and IDENTIFY commands has been changed to support multiple
8381 Client ID's per command. One can now search for multiple users
8382 in the network by sending only one WHOIS or IDENTIFY command.
8383 Changed the code and the protocol specifications.
8385 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8386 uses silc_server_command_whois_parse to parse the request. */
8388 * If normal server, do not parse the WHOIS and IDENTIFY requests
8389 before sending it to the router. Saves some time.
8391 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8393 * Fixed JOIN command on client library. Wrong number of arguments
8394 used to crash the client.
8396 * Added silc_server_channel_has_global function to check whether
8397 channel has global users or not.
8399 * Added silc_server_channel_has_local function to check whether channel
8400 has locally connected clients on the channel.
8402 * The silc_server_remove_from_one_channel now checks whether the
8403 channel has global users or not after given client was removed from
8404 the channel. It also checks whether the channel has local clients
8405 on the channel anymore. If it does not have then the channel entry
8406 is removed as it is not needed anymore.
8408 * The silc_server_notify now checks on JOIN notify whether the joining
8409 client is one of locally connected or global. If it is global then
8410 the channel has now global users on the channel and that is marked
8411 to the channel entry. Also, it now saves the global client to
8412 global list who is joining and JOINs it to the channel. This is
8413 for normal server, that is.
8415 Changed silc_server_send_notify_on_channel,
8416 silc_server_packet_relay_to_channel and
8417 silc_server_packet_send_to_channel check if we are normal server
8418 and client has router set (ie. global client) do not send the
8419 message to that client, as it is already routed to our router.
8421 * Implemented LEAVE notify type handling in silc_server_notify
8424 * Tested LEAVE command in router environment successfully. Tested
8425 with two routers, two servers and two clients.
8429 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8431 * Implemented SIGNOFF notify type handling in silc_server_notify
8434 * silc_server_remove_id now removes the client entry from all channels
8435 it has joined and thusly sends SIGNOFF notify type.
8437 * Rewrote the NAMES list generation in server by removing two excess
8438 loops. The lists are created now inside one loop.
8440 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8442 * silc_server_remove_channel_user checks now also global list
8443 for channel and client.
8445 * silc_server_new_channel_user checks now both local and global
8446 list for channel and client. Fixed a bug in client id decoding.
8447 Used to decode wrong buffer.
8449 * silc_server_channel_message checks now both local and global
8450 list for channel entry.
8452 * Tested channel joining (hence JOIN) in router environment
8453 successfully. Tested with two routers, two servers and two
8456 * Tested channel message sending in router environment successfully.
8458 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8460 * Added silc_server_save_channel_key into server.[ch] to save the
8461 received channel key in Channel Key payload processing. It is
8462 also used in JOIN command reply handling.
8464 Equivalent function silc_client_save_channel_key added into
8465 client.[ch] into client library.
8467 * Changed JOIN command reply to send information whether the channel
8468 was created or not (is existing already) and the channel key
8469 payload. Changed protocol specs accordingly.
8471 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8472 the request was sent by ID and not by nickname. Crashed on
8475 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8477 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8478 now correctly save the received data.
8480 * silc_server_free_sock_user_data now notifies routers in the
8481 network about entities leaving the network.
8483 At the same time implemented functions silc_server_remove_id
8484 and silc_server_send_remove_id to receive and send REMOVE_ID
8485 packets. The packet is used to notify routers in the network
8486 about leaving entities. The ID removed will become invalid in
8489 * Added function silc_idlist_del_server into server. Removes and
8490 free's server entry from ID list.
8492 * silc_server_private_message function now checks, if we are router,
8493 that the destination ID really is valid ID, naturally.
8495 * In router when NEW_ID packet is received (for new client) the
8496 hash of the Client ID is saved in the ID Cache but the
8497 client->nickname is set to NULL, instead of putting the hash
8500 IDENTIFY command now also checks that client->nickname must be
8501 valid. If it is not if will request the data from the server who
8502 owns the client. Added new function
8503 silc_server_command_identify_check.
8505 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8506 to set the command to already allocated Command Payload.
8508 * Tested private message sending in router environment with two
8509 routers, two servers and two clients. Fixed minor bugs and now
8512 * Fixed segfault from client's NAMES command. Used to crash if
8515 * Forwarded packets must not be routed even if it is not destined
8516 to the receiver. Changed server code comply with this.
8518 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8520 * Added `require_reverse_mapping' boolean value to ServerParams
8521 structure. If TRUE (not default) the server will require that
8522 the connecting host has fully qualified domain name.
8524 If the reverse mapping is not required and hostname could not be
8525 found the IP address is used as hostname.
8527 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8529 * Implemented version string checking to both client and server.
8530 The check is incomplete currently due to the abnormal version
8531 strings used in development version of SILC.
8533 * Changed all command functions in server to use the new
8536 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8538 * Changed char *data to unsigned char *data in ID Cache system to
8539 support binary data as ID Cache data. Changed code to support
8540 binary data in lib/silccore/idcache.c.
8542 * Renamed silc_server_packet_relay_command_reply to
8543 silc_server_command_reply as it is normal packet receiving
8544 function. Rewrote the function to accept command replys for
8545 servers and not only for clients.
8547 * Mark remote router always as registered server if we are connecting
8548 to it. Otherwise, commands sent by the router to us are ignored.
8550 * All ID List find routines now returns the ID Cache Entry pointer
8551 as well if requested.
8553 * WHOIS command works now in router environment, tested with two
8554 routers, two servers and two clients.
8556 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8557 in router environment (as it is almost equivalent to WHOIS) but
8558 hasn't been tested thoroughly. Added new functions:
8560 silc_server_command_identify_parse
8561 silc_server_command_identify_send_reply
8562 silc_server_command_identify_from_client
8563 silc_server_command_identify_from_server
8565 * Disabled route cache adding because adding two different ID's with
8566 same IP replaces the old cache entry thus giving wrong route.
8567 The entry->router->connection is always the fastest route anyway
8568 so route cache may not be needed. Of course, new routes maybe
8569 established after receiving the ID when the entry->router->connection
8570 might not be anymore the most optimal.
8572 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8574 * Add route cache for received ID for fast routing.
8576 * Added silc_server_packet_route to route received packet on router
8577 that is not destined to us.
8579 * Renamed silc_server_get_route to silc_server_route_get.
8581 * Added id_string and id_string_len fields into SilcServer to
8582 include encoded ServerID for fast comparing without excess
8583 encoding of the ID's.
8585 * Cleaned up WHOIS command on server side. Added following static
8588 silc_server_command_whois_parse
8589 silc_server_command_whois_check
8590 silc_server_command_whois_send_reply
8591 silc_server_command_whois_from_client
8592 silc_server_command_whois_from_server
8594 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8595 arguments in command replies. All command functions should be
8596 updated to use this macro.
8598 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8600 * Minor typo fixes on command reply handling on server.
8602 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8604 * Added silc_server_command_add_to_channel internal routine to add
8605 the client to the channel after router has created the channel and
8606 sent command reply to the server.
8608 * Added generic silc_server_send_command to send any command from
8611 * Use static buffer with ID rendering instead of duplicating data.
8613 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8615 * Fixed a channel user mode bug when joining to a channel server gave
8616 everybody channel founder rights, oops.
8618 * We mark ourselves as the router of the incoming server connection
8619 if we are router ourselves. This way we can check in some packet
8620 sending functions whether it is locally connected server. For
8621 incoming router connections we put NULL.
8623 * For router sending packets locally means now always sending the
8624 packet cell wide; to local clients and local servers. For normal
8625 server sending packet locally means sending it to only local
8628 * Fixed the JOIN command to really work in router environment. If the
8629 channel is created it is always created by the router. Router is
8630 also responsible of making the initial joining to the channel,
8631 sending JOIN notify to the sending server and distributing
8632 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8633 does not exist server doesn't do anything else but forward the
8634 command to the router which performs everything.
8636 * Added silc_server_send_channel_key function to send the Channel Key
8639 * Added silc_server_create_channel_key to create new channel key. The
8640 channel key is now re-generated everytime someone joins or leaves
8641 a channel, as protocol dictates. Note: channel->key_len is the
8644 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8646 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8647 packet_receive.[ch] to separate packet sending and receiving
8648 routines. The server.[ch] now includes everything else including
8649 actual packet processing (writing and reading data) and other
8652 Renamed silc_server_private_message_send_internal to
8653 silc_server_send_private_message. The routine is still though
8654 used only to relay private messages as server does not send
8655 private messages itself.
8657 Renamed silc_server_new_channel to silc_server_create_new_channel
8658 and added new function sicl_server_new_channel that handles the
8659 incoming New Channel packet. Added also new sending function
8660 silc_server_send_new_channel to send New Channel Payload.
8662 * Added new function silc_server_notify to process incoming notify
8663 packet to the server/router. Server may then relay the notify
8664 to clients if needed.
8666 * Added new function silc_server_new_channel_user to process incoming
8667 New Channel User packet. Router will redistribute the packet and
8668 send JOIN notify to its local clients and locally connected servers
8669 if needed. Normal server will send JOIN notify to its local client
8670 on same channel when received this packet. Added also corresponding
8671 sending function silc_server_send_new_channel_user to sent the
8674 * Added boolean route argument to send_notif_to_channel and
8675 packet_send_to_channel functions to attempt to route the packet
8676 if it is TRUE and send only locally if it is FALSE.
8678 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8680 * silc_server_replace_id now broadcasts the received replace ID
8681 packet if it is not broadcast packet already. The router must
8682 broadcast to inform other routers about changed ID.
8684 * Added backpointer to server's router into SilcServer context in
8685 silcd/server_internal.h.
8687 * Fixed silc_server_packet_broadcast to send correct broadcast
8690 * The channel key is now distributed to the local client as soon
8691 as it is received from the router (in router environment) so that
8692 no other packet may be sent for the channel until client has
8695 * silc_server_remove_channel_user now broadcasts the received
8696 Remove Channel User packet if it is not broadcast packet already.
8697 The router must broadcast to inform other routers about removed
8700 * Added users field into SilcPacketContext that is a reference count
8701 of the context. One can increase the reference count by calling
8702 silc_packet_context_dup which is now changed to just increase the
8703 reference count instead of duplicating the data. The reference
8704 count is decresed by calling silc_packet_context_free that will
8705 free the data after the reference count hits zero.
8707 For now on the packet context and everything allocated into it
8708 (including the raw packet from network) must be freed by calling
8709 the new silc_packet_context_free function. Added also new function
8710 silc_packet_context_alloc that must be used now to allocate the
8711 context. This also means that if a routine is asynchronous from
8712 silc_[client/server]_packet_parse_type the packet context must
8713 be duplicated by calling silc_packet_context_dup. Otherwise it
8714 gets free'd after silc_[client/server]_packet_parse_type returns.
8715 Also, one must remember that if packet is duplicated then its
8716 reference count must be decresed by calling the free function as
8717 many times as it was duplicated.
8719 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8720 from both client and server.
8722 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8724 * Made joining to a channel working in router environment.
8726 * Cleaned up JOIN command on server side and create function
8727 silc_server_command_join_channel internal routine to make the
8730 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8732 * Changed silc_command_pending list to SilcDList. Also, added
8733 `ident' field to SilcServerCommandPending structure to identify
8734 the reply and to call correct callback.
8736 Added silc_server_command_pending_check function to replace the
8737 corresnponding macro. The silc_command_pending list is not
8740 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8741 to set identifier to previously allocated Command Payload. It
8742 is used to set identifier for command when resending Command
8745 * Added silc_command_payload_encode_payload to encode Command
8746 Payload buffer from SilcCommandPayload structure.
8748 * Added silc_argument_payload_encode_payload to encode Argument
8749 payload buffer from SilcArgumentPayload structure.
8751 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8753 * Changed WHOIS command to support router connection on server side.
8754 The whois request is always sent to router unless the server is
8755 standalone server. After server has received the reply from the
8756 router will it send the reply to the client.
8758 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8759 broadcast received broadcast packet. The function is used only
8760 by router. The broadcast packet is always sent to the router's
8763 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8764 render given ID to printable string, for log files for example.
8766 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8768 * Made basic router to router connections working. At least they
8769 can now connect to each other but nothing really works the way
8770 they are supposed - yet.
8772 * Added new initiator token to RouterConnection configuration
8773 file in silcd/serverconfig.[ch]. It is used to tell whether we
8774 are the initiator to the remote router or whether we'll expect
8775 the other end to connect.
8777 * Moved registering of listener task to silc_server_init, hence
8778 the server starts listenning as soon as it is run, even if it
8779 does not have connections to other routers. Let's see how well
8782 * Changed default connection retry timeouts for more suitable in
8785 * Removed cipher and such arguments from silc_idlist_add_client
8786 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8787 Added new function silc_idlist_add_data to add the keys and stuff
8790 * Added SilcIDListData structure and added it to SilcClientEntry
8791 and SilcServerEntry as their first field in the structure. This
8792 way we can explicitly cast the ID entries to the SilcIDListData
8793 structure and get common data for the entries. In past, we had
8794 to first check what type of connection it is and then cast it to
8795 correct ID entry type. Now, we can directly cast the opaque
8796 pointer to the SilcIDListData (no matter what ID entry it actually
8797 is) and get the data needed.
8799 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8801 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8802 in some circumstances even if threre were timeout tasks, though not
8803 IO tasks, but tasks anyway. Now fixed.
8805 * Defined SilcServerConnection structure to hold connection specific
8806 stuff about directly connected servers and routers. The definition
8807 is currently in silcd/server_internal.h. I thought about having
8808 a bit more important role fro this struct but for now it is used
8809 only when connecting to other server (or router actually).
8811 * Added connecting retry support in server when connecting to
8812 router(s). The retry feature implement exponential backoff
8813 algorithm. Also, added SilcServerParams structure to hold default
8814 parameters for server. For now, it include these retry settings
8815 and are hard coded. After server is moded to be as Silc Server
8816 Library this structure will be more important.
8818 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8820 * Changed client librarys channel->clients table to SilcList and
8821 changed code accordingly.
8823 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8825 * Changed client's channel table to SilcList and changed code
8826 accordingly. Also changed SilcChannelClientEntry to include back-
8827 pointer to the channel so that client entry can use that structure
8828 as list as well and we have fast cross-reference to the channel.
8829 This change dramatically decreased the complexity of channel
8830 handling with client entry and vice versa (removed one extra
8831 loop when searching for channel entry from many functions).
8833 * Changed server->sim from table to SilcDList and changed code
8836 * NAMES command can now be used from user interface. It will show
8837 the user list on the channel, neatly.
8839 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8840 Code now saves realname of the user if it becomes available.
8842 * Renamed configure.in to configure.in.pre and made ./prepare
8843 script to automatically add correct version string to
8844 configure.in which it creates from configure.in.pre.
8846 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8848 * NAMES command reply now shows users mode with the nickname when
8851 * Moved silc_client_ch[u]mode[_char] functions from
8852 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8853 place sucks, they are utility functions and should be in some
8856 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8858 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8861 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8865 * Added TRQ (efficient deque and list library) into lib/trq. This is
8866 a very good list library that is currently used in the SILC. Defined
8867 SilcList API over the library because I didn't like the API very
8868 much. See lib/trq/silclist.h for the API and examples of how to
8869 use the API. Fixed various places in the code to use the new
8870 SilcList API. The SilcList is meant for lists that has a structure
8871 already defined as a list. It is not suitable to add just some
8872 context to the list (in TRQ, the context is the list actually).
8874 So, I defined SilcDList that can be used for the purpose where
8875 predefined list structure does not exit. This can be used as
8876 such list. Now some context just can be added to the SilcDList.
8877 Currently this list is not used in the SILC just yet, though there
8878 are a lot places where this can replace dynamically allocated
8879 tables and I will fix these places, later, to use SilcDList.
8880 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8881 and use TRQ internally).
8883 Also fixed some annoying warning messages that the original TRQ
8884 code generated. Also minor changes to TRQ's Makefile.in.
8886 * Added support for querying by Client ID to both WHOIS and
8887 IDENTIFY commands into server, as required by the protocol.
8889 * Removed method function pointers from SilcBuffer structure. They
8890 weren't used to anything and just increased the context size for
8891 no good reason. This change also made silc_buffer_alloc and
8892 silc_buffer_free functions inline functions.
8894 * Disabled command flooding detection support until it's fixed so
8895 that it accepts commands in but does not execute them more than once
8898 * Added silc_net_localhost(), to return local hostname, into
8899 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8900 that must be initialized before calling silc_client_init.
8902 * Added new function: silc_server_send_notify_on_channels to send
8903 notify messages to all channels client has joined. It is assured
8904 that the message is sent only once per client.
8906 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8907 lib/silcutil/silcutil.[ch] as silc_format function. The new
8908 function is generic and is used by server as well, not only by
8909 the logging routines.
8911 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8912 the provided version string was not acceptable. Added new function:
8913 silc_ske_check_version into lib/silcske/silcske.h. The function
8914 must be implemented by the application (client or server) and it
8915 does not reside in the SKE library. The function checks the version
8916 string remote end sent.
8918 * Added back pointers (to opaque context and to SilcSocketConnection)
8919 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8921 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8922 duplicate packet context structure.
8924 * Changed `notify' client operation to send same arguments as client
8925 receives from server except for ID's. ID's are mapped to correct
8926 ID entry and that is returned. Also, if channel entry is not sent
8927 by server but the notify is for channel the channel entry is sent
8928 to application (otherwise application doesn't know that it is for
8929 channel (library gets it from packet's Destination ID)).
8931 * Added silc_client_remove_from_channels into client library to
8932 remove a client from all channels it has joined to. Used when
8933 received SIGNOFF notify from server. Added also new function
8934 silc_client_replace_from_channels to replace old ID entry with
8935 new ID entry on all channels. Used when received NICK_CHANGE
8938 * Fixed ID Cache list handling in silc_idlist_get_client in
8939 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8940 to get (or query) client by ID.
8942 * Updated TODO list.
8944 * Added connection authentication status message defined by the
8945 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8946 support for these into the code in client and server side.
8948 * Added generic function silc_client_send_command to send any command
8949 with variable argument list. Application should use this function
8950 to send commands if the command functions provided by the library
8951 does not suite for the application's user interface needs.
8953 * Added new `failure' client operation. Application is notified about
8954 received failure packet if client is executing a protocol. In this
8955 case the protocol's execution has failed.
8957 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8958 is required by the protocol.
8960 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8961 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8964 * Added status flag to SilcSKE object to indicate realtime status
8965 of the SKE protocol.
8967 * Application receives now exactly same command reply arguments as
8968 the library receives from server. However, if ID is received the
8969 corresponding ID entry is returned to the application (eg. Client
8970 ID is mapped to correct SilcClientEntry entry and that is returned).
8971 Changed command_reply client operation due to this change.
8973 * Changed all ID's in commands and in command replys as ID Payloads.
8974 Change affected both client and server side codes.
8976 All ID's sent in SILC network (with execption of ID's in SILC
8977 Packet header) are sent in ID Payload to support variable length
8980 * Server now notifies nick changes and notifies all clients on
8981 the channels about the new nickname (about the new Client ID,
8984 * Implemented CMODE command to change channel modes. Supports all
8985 channel modes defined by the protocol specs except ban and invite
8986 lists. (Also, private channel key mode is supported but support for
8987 setting private channel key in client is missing, thus, this mode
8988 has no effect on client side (except that server requires that the
8989 client uses private channel key and normal channel traffic does not
8992 Also, invite mode works per se, but INVITE command does not work
8993 yet correctly, so you can set channel as invite only channel but
8994 inviting clients to the channel does not work (it is yet to be
8995 thought what's the best way to do it).
8997 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8998 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8999 Implemented CUMODE command to change user's mode on the channel.
9000 Supports all modes defined by the protocol specs.
9002 * Added NAMES command reply to return users modes on the channel.
9004 * Removed unnecessary and slow ciphers from lib/silccrypt.
9006 * Set SO_KEEPALIVE option to connection sockets by default.
9008 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
9010 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
9011 redefined the Notify Payload into protocol specs.
9013 * Added silc_id_payload_parse_id to get ID directly from raw
9016 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9018 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
9019 accept searching by Client ID as well.
9021 * Added support for LEAVE and SIGNOFF notify types in client library.
9023 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
9024 to parse ID Payload from raw data.
9026 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9028 * Added flags parameter into silc_ske_assemble_security_properties
9029 function in lib/silcske/silcske.[ch].
9031 * Changed notify client operation to fit better for notify messages
9032 sent by server. The notify payload received from server is now
9033 passed to the application (after parsing it to SilcNotifyPayload).
9034 It is application's responsibility to retrieve the arguments
9035 from the payload and show the message the way it wants. The message
9036 sent by server is implementation specific.
9038 * Changed public keys to comply with the protocol specification.
9039 Old public keys are not supported anymore and are not compatible.
9041 * Removed nickname from Channel Payload as the latest draft removed
9042 it. The client must resolve the nickname from the NAMES command
9043 reply received when it joined the channel.
9045 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
9047 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9049 * Fixed some errors in protocol specification drafts.
9051 * Created lib/silccore/silcnotify.c to implement Notify Payload
9052 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
9053 generic payloads described by protocol specifications. The file
9054 includes implementations for ID Payload and Argument Payload.
9056 * Changed Command Payload implementation to use the new Argument
9057 Payload. Changed command_xxxx_payload to command_payload_xxxx
9058 to comply with SILC coding conventions.
9060 * Added suppport for Argument Payload handling in Notify Payload
9061 implementation as protocol requires it. Added the new support
9062 into server and client lib as well.
9064 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9066 * Added support for multiple nicknames on same channel. [n] is
9067 added locally to the nickname if there are more than one same
9068 nicknames on the channel.
9070 * Server now sends all nicknames that matched WHOIS request.
9071 Client also shows the list received from server.
9073 * Added TOPIC command to client side. User can now set and show
9074 current topic on channel.
9076 * Added MOTD command to client and server. Also, server sends the
9077 motd when client connects to the server.
9079 * Changed version strings to comply ISO 8601.
9081 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9083 * Fixed protocol error handling in client library. It should now
9084 cope even if the SKE fails for some reason.
9086 * Made new protocol specification drafts for submitting to IETF.
9088 * Implemented TOPIC command to server in silcd/command.c.
9090 * Added two new notify types into lib/silccore/silcnotify.h:
9091 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
9092 notify nickname change and topic setting/change on a channel.
9094 * API change of command_reply operation in client library. The
9095 application gets now the status type received from server as well.
9097 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9099 * Removed the function just added to lib/silcutil/silcschedule.[ch].
9101 * Cras fixed and optimized the packet handling even further and
9102 it should work now. Minor change to the prototype of function
9103 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
9105 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9107 * Added new function into lib/silcutil/silcschedule.[ch]:
9108 silc_schedule_with_fd to select() a specified fd. The function
9109 returns after timeout expires or data arrives or goes. The
9110 function is used by packet routines to wait that all data is
9111 received from network.
9113 * Fixed data reading from network in lib/silccore/silcpacket.c.
9114 The code now assures that all data is read from the fd and then
9115 continues packet processing. This was a bug fix since the code
9116 used to drop some data in some circumstances.
9118 * Added new function into lib/silcclient/client.[ch]:
9119 silc_client_start_key_exchange to start key exchange after
9120 connection has been established to server. The code internally
9121 now uses this funtion but its main purpose was to provide it
9122 for applications that perform their own connecting. After
9123 application has created a connection it merely calls this
9124 function to start the key exchange between client and server.
9125 The library takes care of everything else after that.
9127 Updated also lib/silcclient/README to explain the usage of
9130 * Do not send to application information that connection has
9131 been established. Application gets notified it by connect
9134 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9136 * Applied cras's patch to add silc_schedule_one function. The
9137 function runs scheduler once and returns.
9139 * Fixed the scheduler after cras messed it up. The timeout
9140 handling works now as it's supposed to work.
9142 * Added into lib/silccore/ silcnotify.h to include notify
9143 message types support. Changed silc_server_send_notify*
9144 functions, in server.[ch], to support those new notify types.
9145 Added the support for the notify types into client library,
9146 as well. Added new notify client operation into ops.h in
9149 * Changed silc_server_packet_send_to_channel to send normal
9150 packets instead of just channel message packets. The function
9151 is now used to send the notify packets to channels. It is not
9152 used to send channel message packets anymore, as server never
9155 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
9156 va_arg()s as it seems to require it nowadays. I guess, if SILC
9157 is compiled with older va_arg() the new code should work anyway.
9159 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9161 * Splitted core library. Core library (lib/silccore) includes
9162 now only SILC protocol specific core (and common) components.
9163 Created new utility library (lib/silcutil) that includes more
9164 generic purpose stuff. The stuff for util library was taken
9165 from the old core library. This was minor and easy split.
9167 * Created SILC Client Library (lib/silcclient) that includes
9168 implementation of the SILC client without user interface. This
9169 was major move from silc/ directory. The code has been changed
9170 so that it is transparent towards the user interface. The
9171 silc/ directory includes now the same user interface as before
9172 and it uses the new client library. Read lib/silcclient/README.
9173 Basicly, the client library performs everything else related
9174 to SILC except user interface handling. Also, configuration
9175 files are considered to be part of user interface and library
9176 does not handle them.
9178 This change also changed a lot of structures, function naming etc.
9179 Most important change was that SilcClientWindow object was
9180 renamed to SilcClientConnection in the client library. Created
9181 also new file lib/silcclient/ops.h. Also added new files
9182 silc/local_command.[ch] and silc/client_ops.[ch].
9184 All these changes were made to make it easier for user interface
9185 designers to create what ever user interface for the SILC client
9188 It is also expected that the server will be moved to lib
9189 directory as well and SILC Server Library will be created;
9190 sometimes in the future.
9192 * Removed Local commands from lib/silccore/silccommand.h as
9193 they are application specific and new client library does not
9194 handle any of those anymore.
9196 * Several functions moved to lib/silcutil/silcutilc.[ch] from
9197 old client implementation in silc/.
9199 * Added support for callback functions in SILC_LOG_* macros.
9200 Application can now set its own callbacks that will be called
9201 instead of using the default functions that will always print
9202 the debug messages to stderr (or stdout). Also, debugging can
9203 now be disabled by setting silc_debug to FALSE and re-enabled by
9204 setting it to TRUE. Note, that logging will still work even
9205 if debugging is disabled.
9207 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
9208 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
9209 silc_log_reset_debug_callbacks.
9211 * To enable debugging in silc client one must give now -d
9212 option on command line.
9214 * Changed silc_schedule_init to automatically allocate task queues
9215 if they are not allocated before calling it.
9217 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9219 * Added GMP 3.1 into math library.
9221 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9223 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
9224 a channel in SILC network. The packet is used by servers and
9225 routers to notify other routers that user has left a channel.
9226 This little feature was missing until now. Added the feature
9227 to protocol specification as well.
9229 Added functions: silc_server_send_remove_channel_user and
9230 silc_server_remove_channel_user into server.[ch].
9232 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
9233 lib/silccore/silcpacket.h. However, they are not implemented
9236 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9238 * Fixed joining to a channel and sending channel messages
9239 between server and router. The channel message sending should
9240 now work inside a cell.
9242 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9244 * Fixed the private message sending between server and router.
9245 The private message sending should now work inside a cell.
9247 * Added silc_server_replace_id into server.[ch] to replace
9248 existing ID in the SILC network.
9250 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
9251 and silc_idlist_replace_server_id into idlist.[ch] in server.
9253 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9255 * Fixed the server to server connections. Server can again now
9256 connect to router. Router to router connections probably does
9259 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9261 * Added dynamic protocol registering support. Now protocols can
9262 registered and unregistered on the fly. Patch by cras.
9264 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9266 * Added lib/contrib directory to hold routines that some platforms
9267 don't have but are needed by SILC.
9269 * Added getopt.c, getopt1.c and getopt.h from GNU C library
9270 into lin/contrib to provide getopt() and getopt_long() for
9271 those who don't have it.
9273 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9275 * Added AWAY command to client. When away message is set and
9276 client receives a private message packet the client automatically
9277 replies to the sender with the away message.
9279 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
9280 bug seemed to be the cause of recent problems when compiling
9283 * Added version detection support to SKE protocol specification
9284 and added the new changes to the SKE implementation as well.
9285 There were other minor changes in the SKE protocol as well.
9287 Many changes in lib/silcske/silcske.[ch] and in
9288 lib/silcske/payload.[ch].
9290 * Added ^U functionality, clear input line. Patch from cras.
9292 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9294 * Mainly small bugfixes on core library. Fixed some debugging
9295 logging and buffer overflow in silclog.c.
9297 * Updated config.sub and config.guess on the distribution tree.
9299 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9301 * Added command lagging support in server. Client may execute
9302 commands now only once in two seconds.
9304 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9306 * Optimized packet reception. MAC computation and checking is now
9307 also more optimized. A lot previously duplicated code is now
9308 used as generic by both client and server.
9310 * Fixed key pair generation in clientutil.c
9312 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9314 * Added into lib/silccore/silcbufutil.[ch] new function;
9315 silc_buffer_realloc.
9317 * Moved generic packet sending/encryption functions to
9318 lib/silccore/silcpacket.[ch] from client and server. Some
9319 rewriting of the functions.
9321 * Moved all generic packet reception/decryption functions to
9322 lib/silccore/silcpacket.[ch] from client and server. The
9323 packet processing is now much cleaner in both client and server.
9324 These were major changes in both client and server.
9326 * Created many common functions in server to do packet sending.
9327 Previously code were duplicated a lot, this has been removed
9330 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9332 * Rewrote major parts of the ID cache system. Don't know
9333 whether it is better now or not but at least the API is more
9336 * Major rewrite on ID cache stuff on client because of the ID
9337 cache API changes. Added idlist.c to client.
9339 * Also major rewrite on ID cache stuff on server as well.
9340 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9341 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9342 in hand, instead they are all put into the ID cache system now.
9343 All server_idlist_* routines uses ID cache now instead of
9344 traversing its own lists (those lists does not exist anymore).
9345 SilcIDList though still exists. Also, SilcXXXEntry's are
9348 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9350 * Finally made the SKE implementation compliant to the protocol
9351 specification. All mp integers are now binary encoded as
9352 opposed being HEX encoded.
9354 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9357 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9358 functions: silc_[encode/decode]_pem. Also added function
9359 silc_encode_pem_file to PEM encode with newlines ('\n') for
9362 * SILC public keys are now encoded either PEM or binary. Same
9363 option is for private keys as well. By default private keys
9364 are binary encoded and public keys PEM encoded. Silly HEX
9365 encoding were removed.
9367 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9368 function to create fingerprints.
9370 * Fixed a bug in SHA1; does not change the original data anymore.
9372 * Partly implemented INFO command on client and server side.
9373 Fixed CLEAR command. Changes to SERVER command; show current
9374 server(s) when giving command without arguments. Added
9375 VERSION command to client.
9377 * Added check to server that unregistered connections cannot
9378 execute commands (unless it is specificly allowed).
9380 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9382 * Fixed screen refresh.
9384 * Fixed channel joining bug from client. On some circumstances
9385 client tried to join to a channel it had already joined.
9387 * Added public key verification process into client's protocol.c.
9388 The client now verifies the public key from user and saves
9389 it into ~./silc/serverkeys/ directory.
9391 Added into: clientutil.[ch]: silc_client_verify_server_key.
9393 * Changed SKE protocol's silc_ske_initiator_finish function
9394 to accept callback function that verifies the received public
9395 key. Removed old silc_ske_verify_public_key function.
9397 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9399 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9400 silc_pkcs_private_key[_data]_set.
9402 * Made the password and public authentication more cleaner in
9403 server's protocol.c.
9405 * Removed historic and obsolete protocol `channel_auth' from
9406 both client and server.
9408 * Removed wrong way of sending command status messages from
9409 server to client in server's command.c. The old way violated
9410 protocol specification.
9412 Changes to silccore/silccommand.[ch]: removed
9413 silc_command_encode_status_payload -> not needed anymore,
9414 changed silc_command_encode_payload_va to accept extra
9415 argument on variable argument list. The argument type must
9416 now be provided to the function. Also, added new function:
9417 silc_command_encode_reply_payload_va which is same as
9418 normal command_encode_payload_va except command status type
9419 is provided as extra argument.
9421 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9423 * Added ~./silc directory handling. The directory includes the
9424 public and private keys for the client.
9426 Added silc_client_check_silc_dir, silc_client_create_identifier
9427 and silc_client_load_keys.
9429 * Implemented SILC protocol compliant public key. Added public
9430 and private key saving to and loading from files.
9432 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9433 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9434 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9435 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9436 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9438 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9439 silc_pkcs_load_[public/private]_key.
9441 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9443 * Added silc_server_get_route (route.[ch]) to get connection
9444 data for the fastest route for given ID.
9446 * Implemented INVITE command on client and server. The command
9447 were re-defined in the SILC Protocol Specification and the
9448 implementation now complies with the specification.
9450 * Implemented PING command on client and server.
9452 * Implemented NAMES command on client and server. The server side
9453 supports currently only normal server not router server yet.
9454 Some changes to NAMES definition in SILC protocol specification.
9456 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9458 * Implemented LEAVE command on client and server.
9460 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9461 again. This change was made to the protocol as well. Server
9462 should not violate the protocol specification anymore.
9464 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9466 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9467 was tested. SOCKS4 was not but should work anyway.
