165 It is not able to send requested attributes in WHOIS command,
166 and also receive and process requested attributes. Added
167 silc_client_attribute_[add|del] and silc_client_attributes_get
168 functions. Added also `ignore_requested_attributes' to the
169 SilcClientParams to not use attributes in client. Affected
170 files are lib/silcclient/command.c, client_attrs.[ch],

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

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

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

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

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

489 * Return NO_SUCH_CHANNEL error in USERS for channel that is
490 secret or private, otherwise it's possible to find out
491 whether a secret channel exists or not. Affected file
494 * If CMODE change fails during the mode setting, assure that
495 the old mode mask is set for the channel back. Affected
496 file silcd/command.c.
498 * Fixed passphrase saving on +a channel on normal server
499 after successful JOIN command. Affected file silcd/command.c.
501 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
503 * Remove server/router operator privileges in DETACH command,
504 since it's possible to resume to server where these
505 privileges would not be allowed for the client. Affected
506 file silcd/command.c.
508 * Do not set to wait for backup in rehash of the server.
509 Affected file silcd/server.c.
511 * Do not check listener sockets when counting how many
512 socket connections we have. Affected file is
515 * Do not announce disconnected clients that are remaining
516 in history (for WHOWAS). This is because SIGNOFF notify
517 for these has been sent earlier already. Affected file
520 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
522 * Buffer overflow with CUMODE command's mode->mode character
523 conversion. Reported by Ville Räsänen. Affected file

526 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
528 * Allow heartbeat packets to go disabled connections anyway.
529 Affected files silcd/server.c and silcd/packet_send.c.
531 * Do not broadcast New Channel packets with List flag set
532 in the packet to backup routers. The router must check
533 for the correctness of the packets before sending them.
534 It is possible that router will have enforce Channel ID
535 change and this would cause desync in the backup router.
536 Affected file silcd/packet_receive.c.
538 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
539 are handled in list parsing. They are not list packets
540 anymore. Affected file silcd/packet_receive.c.

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

794 * Save the channel passphrase when received succesful JOIN
795 command reply from router, on normal server. Otherwise
796 joinig +a channels from normal server is not possible.
797 Affected file silcd/command.c.
799 * Fixed a bug in TOPIC_SET notify handling. The notifier
800 may be other than client too, like server or channel.
801 It expected it to always be only client and ignored the
802 notify. Affected file silcd/packet_recieve.c.
804 * Removed some (unnecessary) debug printing from
805 lib/silccore/silcid.c and lib/silccore/silcargument.c.
807 * Do not force CMODE_CHANGE when server is announcing new
810 Router announces stuff only after server reannounces channel
811 after CHANNEL_CHANGE notify.
813 These fixes optimizes the announcing procedure, and perhaps
814 fixes some problems too. Affected file silcd/packet_receive.c.
816 * Fixed SERVER_SIGNOFF sending to local clients. It was
817 totally broken and sent the notify to all local clients,
818 instead of only to those that was on same channel as the
819 signing off clients. Affected file silcd/server_util.c.
821 * Added -D option to server. It can be used to give debug
822 level. The levels are from 0 - 99, and are predefined for
823 smooth server debugging. (see silcd.c for the predefined
824 levels). Affected file silcd/server.c.
826 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

829 properly when disconnecting from server. Affected file
830 irssi/src/silc/core/client_ops.c.
832 Tue Jun 18 17:14:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
834 * When authenticating as founder during JOIN command, check
835 that the one authenticating becomes the only founder on the
836 channel. Affected file silcd/command.c.
838 * Better checking for founder mode setting when CUMODE_CHANGE
839 notify is received. Affected file silcd/packet_receive.c.
841 * Close all connections when shutting down the server by sending
842 DISCONNECT packet. Close all listeners too when shutting
843 down the server. Affected file silcd/server.c.

846 calling the "disconnect" client operation. Affected file
847 lib/silcclient/client.c.
849 * Handle local errors correctly during resuming. Affected
850 file lib/silcclient/client.c.

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

917 that there isn't anyone else with founder mode on the channel.
918 The one that authenticated will become founder and anyone
919 else is demoted. Affected file silcd/command.c.
921 * Added error printing of any error that has occurred during
922 any command in client library. Affected file is
923 irssi/src/silc/core/client_ops.c.

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

1584 Added new options m and M to CMODE command in Irssi SILC
1585 client to set these modes.
1587 * Deprecated all administrative commands from SILC protocol
1588 since they are highly implementation specific commands.
1589 Updated protocol specs. Moved the old commands in
1590 implementations to private range of command types. Affected
1591 files are silcd/command.c, lib/silcclient/command.c and
1592 lib/silcclient/command_reply.c. Protocol TODO #8.
1594 * Fixed a bug in server where sending unknown command crashes
1595 the server. Affected file silcd/command.c.
1597 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1599 * Added SILC_PROTOCOLVERSION macro to check protocol version
1600 of a socket connection. The affected file is
1601 lib/silcutil/silcsockconn.h.
1603 * Added better error logging in rekey protocol. Affected file
1606 * Do not check public key types in SKE during rekey. Affected
1607 file lib/silcske/payload.c.
1609 * Fixed the rekey protocol with PFS, which was totally broken.
1610 Affected file silcd/protocol.c.
1612 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1614 * Some client implementations quit network by doing first LEAVE
1615 and then immediately SIGNOFF (like Bombyx). We now do check
1616 after a short time after LEAVE notify and check whether the
1617 client is still valid after LEAVE, and if not we remove it from
1618 cache. Affected file is lib/silcclient/client_notify.c.
1620 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1622 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1623 it's good not to have security holes here.
1625 * Fixed a negative refcount situtuation for the config context.
1626 Affected file is silcd/serverconfig.c.
1628 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1630 * ROBOdoc documented lib/silcutil/silcutil.h.
1632 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1634 * Optimized even more the SilcPacketContext structure. Now
1635 totally saved 16 bytes of memory per context after optimization.
1636 Affected files are lib/silccore/silcpacket.[ch].
1638 * Made strict checks for valid SILC IDs. Affected file is
1639 lib/silccore/silcid.c.
1641 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1643 * Changed the object argument for silc_cipher_register,
1644 silc_hash_register, silc_hmac_register and silc_pkcs_register
1645 to const. Affected files are lib/silccrypt/silccipher.[ch],
1646 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1648 * Changed the silc_get_username and silc_get_real_name to
1649 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1651 * Fixed the Irssi SILC Client to use the silc_get_username and
1652 silc_get_real_name insted of glib routines since the glib
1653 routines only corrupt stack. Fixes the Irssi SILC to work in
1654 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1656 * Fixed the Irssi to not use g_get_home_dir since it crashes
1657 or returns garbage on cygwin and corrupts stack. Added function
1658 get_home_dir to Irssi routines. Affected files are
1659 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1661 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1663 * Made some structure optimizations. SFTP memory FS MemFSEntry
1664 entry structure. Optimized SilcTask structure. Optimized
1665 SilcPacketContext structure.
1667 Affected files lib/silcsftp/sftp_fs_memory.c,
1668 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1670 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1672 * And yet again reverted back the config thing since Johnny
1673 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1676 * Fixed memory leaks from config object. Affected files are
1677 silcd/serverconfig.[ch].
1679 * Added support for adding new connections to the server in rehash.
1680 After rehash they take effect.
1682 Added support for changing the maximum allowed connections in
1683 rehash. The number can grow but going smaller is not supported.
1685 Added function silc_server_num_sockets_by_remote to the
1686 silcd/server_util.[ch].
1688 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1690 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1692 * Added preliminary checking during config parsing for a valid
1693 public/private key and removed further checks in the code.
1694 Affected files are silcd/serverconfig.[ch], server.c.
1696 * Moved functions silc_server_drop() and silc_server_daemonise()
1697 from server.c to silcd.c since they are stricly related to
1698 the application activity.
1700 * Reverted a small part of the automatic ref/unref since
1701 it caused a double unref in some situations. Affected
1702 files are silcd/silcd.[ch], server.c, serverconfig.c.
1704 * Added some .cvsignore files in the lib directory.
1706 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1708 * Fixed silc_net_gethostbyaddr to correctly resolve by
1709 address. Affected file lib/silcutil/silcnet.c.
1711 * Fixed the notify relaying to client. The HMAC to be used
1712 with relayed packets ws wrong and caused decryption failure
1713 at the client end. Affected file is silcd/packet_receive.c.
1715 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1717 * Created new branch silc_protocol_1_0_branch.
1719 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1721 * Changed the silc_server_config_* routines to be SilcServer
1722 independent. They are now officially application specific code
1723 and not part of generic server implementation. Affected files
1724 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1726 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1728 * Added automatic referencing of config context in the
1729 silc_server_config_alloc, and automatic unreferencing in the
1730 silc_server_config_destroy. Affected files are
1731 silcd/serverconfig.[ch], silcd/silcd.c.
1733 * Fixed the silc_log_quick handling in the logging routines.
1734 It didn't log quickly when it was TRUE. Affected file is
1735 lib/silcutil/silclog.c. Also the flush delay was set even
1736 if it was 0 in config file. Affected file is
1737 silcd/serverconfig.c.
1739 * Added support for changing key pair of the server in rehash.
1740 Affected file silcd/server.c.
1742 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1744 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1745 too early, before getting the channel entry. Affected file
1746 is silcd/packet_receive.c.
1748 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1750 * Added functions silc_server_config_[ref/unref], these are used
1751 to prevent that the config object is destroyed.
1753 No longer directly affect global variables silc_log_quick and
1754 silc_log_delay, they are first cached inside the config object
1755 and then applied with silc_server_config_setlogfiles().
1757 silc_server_config_set_defaults() is now internal to
1758 serverconfig.c, there are no reasons to show this internal stuff
1761 Affected files are silcd/serverconfig.[ch].
1763 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1764 fprintf's to stderr, since some code may be executed again after
1765 the server went into the background. Affected files are
1768 * Added rehash support. Added function silc_server_rehash() that
1769 will perform all the basic tasks of the rehashing procedure.
1771 * Added command line option `-x, --hexdump'. This will enable the
1772 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1773 The option `--hexdump' implies `--debug'.
1775 * Fixed a bad bug in the logging APIs (silcutil library) where
1776 the application would crash after calling silc_log_reset_all().
1778 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1780 * Fixed the KICKED notify handling in client library to
1781 correctly remove the channel and all entries from the
1782 channel when I was kicked. This bug crashed the client.
1784 Fixed yet another but in KICKED notify handling to remove
1785 the kicked client correctly from the channel.
1787 Affected file is lib/silcclient/client_notify.c.
1789 * Fixed a minor bug in looking up correct client entry
1790 in KICKED notify in server. Affected file is
1791 silcd/packet_receive.c.
1793 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1794 sources correctly to distribution. Fixes --with-gmp option.
1796 * Removed the manual rehashing from ID Cache, and changed it
1797 to use the SILC Hash Table's auto rehash feature. Affected
1798 file is lib/silccore/silcidcache.c.
1800 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1802 * Fixed a bug in the silc_client_nickname_format function that
1803 handles the multiple same nickname formatting. Two clients
1804 with same nickname caused problems after the first one left
1805 and rejoined. It didn't format the nickname correctly.
1806 Affected file is lib/silcclient/idlist.c.
1808 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1810 * Don't change the topic if olod topic is same as new one.
1811 Affected file is silcd/packet_receive.c.
1813 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1815 * Added cross-reference support to the SILC Documentation
1816 generator. All types across all HTML files are now cross-
1817 referenced. Affected files util/robodoc/generator.c and
1818 scripts/silcdoc/silcdoc.
1820 * Added file lib/silcutil/silctypes.h to include all the
1821 arithmetic type definitions and some macros. Removed
1822 includes/bitmove.h and moved macros to silctypes.h.
1824 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1826 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1828 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1830 * Added `type' argument to silc_id_payload_parse_id function which
1831 now returns the type of the ID to the sent pointer. Affected
1832 file is lib/silccore/silcid.[ch].
1834 * Added check for CMODE_CHANGE notify type that mode change is
1835 allowed by the sender. Affected file silcd/packet_receive.c.
1837 * Added check for CUMODE_CHANGE notify type that mode change is
1838 allowed by the sender. Affected file silcd/packet_receive.c.
1839 Added the ID type as CUMODE_CHANGE notify type as argument
1840 to the `notify' client operation. Affected files are
1841 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1843 * Added function silc_client_add_server to the client library.
1844 Added support for resolving also channel and server info when
1845 received unknown entity in notify packet. Affected files are
1846 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1848 * Added function silc_command_get_status to return the command
1849 status from the command reply's argument payload. Affected files
1850 are lib/silccore/silccommand.[ch].
1852 * Added check for KICKED notify type that the kicking is
1853 allowed by the client. Affected file silcd/packet_receive.c.
1855 * Created function silc_get_input which can be used to get input
1856 (echo on or off) from user on command line. Affected files are
1857 lib/silcutil/silcutil.[ch].
1859 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1861 * Optimized silc_server_packet_relay_to_channel function.
1862 Added new function silc_channel_message_payload_encrypt which
1863 can be called directly if channel message payload needs to
1864 be encrypted and is already encoded (no need to call _encode
1865 function). Packet relaying is now done by router without any
1866 extra memory allocations. Affected files are
1867 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1868 silcd/packet_send.c.
1870 * Fixed the INVITE notify handling. It took wrong arguments
1871 as invite list and invite delete. Affected file is
1872 silcd/packet_receive.c.
1874 * Added check for TOPIC_SET notify type that the topic change is
1875 allowed by the client. Affected file silcd/packet_receive.c.
1877 * Added check for INVITE notify type that inviting is allowed by
1878 the client. Affected file silcd/packet_receive.c.
1880 * Changed the silc_server_client_on_channel to return the
1881 SilcChannelClientEntry as well. Moved the function
1882 silc_server_check_cmode_rights to server_util.[ch].
1883 Affected files are silcd/server_util.[ch], silcd/command.c.
1885 * Added function silc_server_check_umode_rights to check whether
1886 changing client's user mode is allowed. Added check for
1887 UMODE_CHANGE notify type that the umode change is allowed
1888 by the client. Affected files are silcd/server_util.[ch],
1889 silcd/packet_receive.c and silcd/command.c.
1891 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1893 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1894 ID length. It ignored that ID can be IPv6 based as well.
1895 Affected file lib/silccore/silcpacket.h.
1897 * Fixed the silc_id_id2str and silc_id_str2id to take the
1898 IPv6 address offset's into consideration. Affecte file is
1899 lib/silccore/silcid.c.
1901 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1903 * Fixed the internal Unix scheduler functions to check for
1904 NULL context they may receive. The affected file is
1905 lib/silcutil/unix/silcunixschedule.c.
1907 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1909 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1910 can specify different directory with --home command line
1911 parameter. Affected files irssi/src/silc/core/client_ops.c,
1914 * SILC-specific commands aren't now executed if the active server
1915 isn't of SILC-type, so there won't be problems with having
1916 IRC and SILC protocol support in same client. Affected files
1917 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1920 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1922 * Improved the signal support in SILC Schedule. Added new
1923 function silc_schedule_signal_call which is used by application
1924 to mark a signal to be called. It is now safe to perform
1925 any kind of tasks in signal callbacks since it is guaranteed
1926 that the application specified signal callback is called
1927 after the signal is over. Affected files are
1928 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1930 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1932 * Added `name' field to SilcChannelPrivateKey to represent
1933 application given name for the key. Moved also the context from
1934 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1935 Added the `name' argument also to the function
1936 silc_client_add_channel_private_key.
1938 Added function silc_client_current_channel_private_key to set the
1939 current channel private key in use.
1941 Added "change" command to KEY command which can be used to change
1942 the current channel private key. Bound the command also to
1943 alt+K (Alt+Shift+k).
1945 Also affected files lib/silcclient/client_channel.c,
1946 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1948 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1950 * Added silc_rng_get_byte_fast function in to the
1951 lib/silccrypt/silcrng.[ch].
1953 * Changed the interface of silc_packet_assemble and the
1954 silc_packet_send_prepare. If silc_packet_assmble is now
1955 called the application does not call silc_packet_send_prepare
1956 because the library will call it automatically. These
1957 interfaces now also return a reference to the outgoing buffer
1958 which includes the assembled packet, which the application can
1959 use to encrypt the packet.
1961 Affected files are lib/silccore/silcpacket.[ch],
1962 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1963 silcd/packet_send.c, server_backup.c and packet_receive.c.
1965 * Fixed a packet sending bug on very high load, where outgoing
1966 packet queue wasn't handled correctly and packets got corrupted.
1967 Affected files are lib/silcutil/*/silc*sockconn.c,
1968 lib/silcclient/client.c and silcd/server.c.
1970 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1972 * Added macro SILC_PACKET_DATALEN which can be used during
1973 packet assembling to check whether the data to be added to
1974 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1975 len is truncated until it fits it.
1977 Added checks for maximum length of channel message payload and
1978 private message payload also.
1980 Added checks for maximum packet length in server and in
1983 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1984 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1985 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1986 lib/silcclient/client_prvmsg.c.
1988 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1990 * Added silc_server_packet_queue_purge call to the
1991 silc_server_disconnect_remote to assure that all data in the
1992 queue before disconnecting is sent to the network. Affected
1993 file silcd/server.c.
1995 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1997 * Added the deleting of server's own ID cache entry to the
1998 silc_server_free function. Free also everything else that
1999 has been allocated in silc_server_init. The affected file
2002 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2004 * Added functions silc_parse_version_string, silc_version_to_num,
2005 and silc_ske_parse_version to parse SILC protocol style version
2006 strings. Affected files lib/silcutil/silcutil.[ch] and
2007 lib/silcske/silcske.[ch].
2009 * Added new configuration params: version_protocol, version_software
2010 and version_software_vendor to specify what version the remote
2011 host must at least be to be able to connect to server. The vendor
2012 string can be regex matched too. Added new function
2013 silc_server_connection_allowed to check maximum number of allowed
2014 connections, and allowed versions for incoming connections.
2015 Affected files are silcd/server.c, server_util.[ch] and
2018 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2020 * Added preliminary support for signals in scheduler. The
2021 signals we care about are now blocked always when the scheduler
2022 is locked. This way we can synchronise the use of signal with
2023 scheduler. It is guaranteed that when signal occurs the scheduler
2024 is not locked, and thus new tasks can be safely added to the
2027 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
2028 to silc_schedule_internal_init and silc_schedule_internal_uninit.
2029 Added new platform specific routines
2030 silc_schedule_internal_signals_[un]block and
2031 silc_schedule_internal_signal_[un]register.
2033 Added new functions to SILC Schedule API:
2034 silc_schedule_signal_[un]register. Each signal that application
2035 is going to use should be registered to the scheduler.
2037 Affected files are lib/silcutil/silcschedule.[ch],
2038 lib/silcutil/*/silc*schedule.c.
2040 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2042 * Check for unauthenticated client and server in the
2043 silc_server_new_client and silc_server_new_server functions.
2044 Affected file silcd/packet_receive.c.
2046 * Added function silc_string_is_ascii to check whether given
2047 string is 7-bit ASCII string. Affected files are
2048 lib/silcutil/silcutil.[ch].
2050 * Added function silc_id_is_valid_server_id into the
2051 silcd/serverid.c and added checking for valid Server ID's in
2052 silc_server_new_server. The Server ID must always be based
2053 on the server's public IP address.
2055 * Added logging of DISCONNECT packet message in the server.
2056 Affected file silcd/server.c.
2058 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2060 * Changed all library interfaces that use Global RNG to also
2061 accept SilcRng as argument. Affected files are
2062 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
2063 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
2064 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
2065 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
2066 lib/silccrypt/rsa.c.
2068 * Added function silc_pkcs_generate_key to the
2069 lib/silccrypt/silcpkcs.[ch] for applications so that they
2070 don't need to do pkcs->pkcs->init calls anymore.
2072 * Remove SilcSocketConnection from the SFTP API since it really
2073 wasn't needed there. The application has the information
2074 saved in its contexts anyway and the SFTP layer doesn't need
2075 know about it. Affected files lib/silcsft/silcsftp.h and
2076 lib/silcsftp/sftp_[server/client].c.
2078 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
2079 The SilcSimContext is not SilcSim.
2081 * Fixed possible buffer overflows in silc_id_render in the
2082 lib/silcutil/silcutil.c.

2086 algorithm list on EPOC. Affected files are
2087 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
2090 * Fixed the handling of third parameter of KICKED notify, since
2091 it was mistakenly updated to SILC Protocol 1.0 even though it
2092 is to be included in 1.1. Since it is not in 1.0 it is not
2093 mandatory, and this fix now handles it only if it is provided,
2094 and it is not error if it is not provided. Affected file
2095 lib/silcclient/client_notify.c.
2097 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2134 file lib/silcutil/silcutil.[ch].
2136 * Added support for specifying multiple public keys for Client
2137 connection section in server configuration file. This makes it
2138 possible to accept multiple public keys from same host, or to
2139 make a section that accepts any incoming host, and have the
2140 accepted public keys listed in the section.
2142 Added functions silc_sever_[find/get]_public_key, added the
2143 support for this actually to all connection sections but only
2144 the Client section is currently allowed to specify multiple
2147 Affected files are silcd/server.c, server_internal.h,
2148 command.c, protocol.c, server_util.[ch], packet_receive.c.

2167 from single host, by checking also the type of the connection.
2168 Fixed also the comparison of number of connections and number
2169 of allowed connections. Affected files are silcd/server.c,
2172 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2251 application does not need to define them. Affected file
2252 includes/silcincludes.h.
2254 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
2255 old name went against naming convention. Applications now
2256 include "silcclient.h" instead of "clientlibincludes.h".
2257 Removed includes/clientlibincludes.h, it is redundant now.
2259 * Renamed includes/version.h to silcversion.h.
2261 * Added really preliminary support for OS/2 into the util
2262 library. Only thread & mutex API is implemented, others
2263 are still to be implemented. Created the lib/silcutil/os2/
2264 directory. Created also file includes/silcos2.h.

2297 * Added `user_count' to the SilcChannelEntry which now tells the
2298 number of users on the channel. The user count is now saved
2299 in normal server of global channels as well. Affected files
2300 silcd/server.c, idlist.h, packet_receive.c and command.c.
2302 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
2303 include file utility functions.
2305 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
2306 instead of calling directly OS routines.
2308 * Fixed NICK change printing in Irssi SILC Client. Fixed
2309 KICKED notify printing in Irssi SILC Client. Affected file
2310 irssi/src/silc/core/client_ops.c.

2318 * ROBOdoc documented the lib/silcske/silcske.h, and improved
2319 the SKE interface a bit.
2321 * Fixed padding problem in PKCS#1. The padding was not actually
2322 random since the random number generator was used incorrectly.
2323 This security bug affects only when encrypting with PKCS#1, and
2324 it is not currently used at all in SILC. SILC only use signing
2325 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
2327 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2385 is now done in silc_core_init() which also fixes autoconnecting
2388 Affected files irssi/src/silc/core/silc-core.c,
2389 irssi/src/fe-text/silc.c.
2391 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2393 * Added new configuration options and blocks:
2394 keepalive_secs, reconnect_count, reconnect_interval,
2395 reconnect_interval_max, reconnect_keep_trying and
2396 require_reverser_lookup. Added ConnectionParam block, and
2397 implemented the connection parameters when connecting as
2398 initiator and when accepting connections as responder.

2401 whether given configuration value has been given already.
2403 Affected files silcd/serverconfig.[c], server.[c].
2405 * Splitted the doc/example_silcd.conf.in. Separated the crypto
2406 algorithm parts and created new file silcalgs.conf, that
2407 is now included from the example_silcd.conf.in.
2409 * Optimized the silc_server_connect_to_router_second to take
2410 the connection configuration object from the SilcServerConnection
2411 object instead of finding it during the connecting phase.
2412 Added the configuration object to SilcServerConnection struct.
2413 Affected files silcd/server_internal.h, server.c.
2415 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2417 * Add the client on channel after it was resolved at the
2418 channel message receiving, and it was not already on the
2419 channel. Affected file lib/silcclient/client_channel.c.
2421 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2423 * Fixed the public key authentication to allocate always the

2437 authentication to be set at the same time.
2439 Added `prefer_passphrase_auth' setting in config file which
2440 can be used to set to prefer passwd auth if both passwd and
2441 public key is set. If not set, public key is preferred.
2442 This has effect only when being initiator (responder will try
2445 Added support for authentication with passphrase and public key
2446 at the same time. The passphrase is tried first always since
2447 it is faster to check.
2449 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2451 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2497 * Fixed the file transfer's key agreement payload to include
2498 zero port also if the hostname is NULL because it could not
2501 Call file transfer monitor callback now also if error occurs
2502 during key agreement protocol.
2504 Changed the silc_client_file_send interface to return the
2505 SilcClientFileError instead of session id. The session ID
2506 is returned into pointer provided as argument.

2523 file lib/silcutil/silclog.c.
2525 * Fixed the channel message payload decryption in the function
2526 silc_channel_message_payload_decrypt to not modify the original
2527 buffer before it is verified that the message decrypted
2528 correctly. Otherwise, next time it is called with correct
2529 channel key it won't encrypt since the payload is corrupted.
2530 Affected file lib/silccore/silcchannel.c.
2532 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2544 * Fixed a bug in hash table internal routine for traversing
2545 the table with foreach callback. The current entry may
2546 become invalid in the callback but it was referenced after
2547 the callback returned.
2549 Do not allow auto rehashing of hash table during the
2550 silc_hash_table_foreach operation, for same reasons as it is
2551 not allowed for SilcHashTableList. Affected files are
2552 lib/silcutil/silchashtable.[ch].
2554 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2556 * Defined DLLAPI into silcincludes.h and silcwin32.h for

2560 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2562 * Fixed private message handling. It used some old code that
2563 caused the client to crash. Affecte file is
2564 lib/silcclient/client_prvmsg.c.
2566 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2568 * Added function silc_client_add_channel,
2569 silc_client_replace_channel_id, and removed functions
2570 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2571 from client library.
2573 * Added cross reference of the joined channels to the
2574 SilcClientEntry, and changed the SilcChannelEntry's
2575 users list to SilcHashTable. The affected files are
2576 lib/silcclient/idlist.[ch].
2578 * Fixed a bug in hash table tarversing. While the hash table
2579 is traversed with SilcHashTableList the table must not be
2580 rehashed. It is now guaranteed that auto rehashable tables
2581 are not rehashed while tarversing the list. Also defined that
2582 silc_hash_table_rehash must not be called while tarversing
2583 the table. Added function silc_hash_table_list_reset that must
2584 be called after the tarversing is over. The affected files are
2585 lib/silcutil/silchashtable.[ch].
2587 * Changed all hash table traversing to call the new
2588 silc_hash_table_list_reset in server and in client library.
2590 * Added function silc_client_on_channel to return the
2591 SilcChannelUser entry if the specified client entry is joined
2592 on the specified channel. This is exported to application as
2593 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2595 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2597 * Fixed founder regaining problem with JOIN command on normal
2598 server. The notify for mode change must be sent always and
2599 not only if !cmd->pending. Affected file silcd/command.c.
2601 * Fixed the WHOWAS command's reply sending to support the
2602 lists correctly. Affected file silcd/command.c.
2604 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2606 * When sending JOIN command to router for processing the
2607 sender's old command identifier was not saved back to the
2608 sender's command context, fixed now. The affected file is
2611 * Create the key in JOIN command of the router did not return
2612 the channel key, added check for this. Affected file is
2615 * Fixed a channel ID update bug in JOIN command reply. Do
2616 not directly upgrade the ID but call the function
2617 silc_idlist_replace_channel_id if the ID was changed.
2618 Affected file silcd/command_reply.c.
2620 * Fixed memory leaks from command calling if it would fail.
2621 Affected file silcd/command.c.
2623 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2625 * Applied patches from cras:
2627 Memory leak fixes around libaries, irssi window resize fix,
2628 new silclist.h and silcdlist.h, all extern inline changed to
2631 * Removed dotconf from lib/dotconf, not needed anymore.
2633 * Removed TRQ from lib/trq, not needed anymore.
2635 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2636 with server connections. Later this will be configurable
2637 in config file after new config file is done. Affected file
2640 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2642 * Fixed a crash in server related to channel announcements.
2643 Affected file silcd/server.c.
2645 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2647 * Fixed memory leaks in silc_server_create_new_channel*
2648 functions. Affected file silcd/server.c.
2650 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2651 which ID was changed. This way the router will send the
2652 user list for the channel again, and server won't be in
2653 desync in some rare circumstances. Affected file is
2654 silcd/packet_receive.c.
2656 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2658 * Check for NULL socket pointer in the function
2659 silc_server_packet_send_to_channel_real. Affected file
2660 silcd/packet_send.c.
2662 * Fixed the BAN notify handling to correctly remove ban
2663 list. Affected file silcd/packet_receive.c.
2665 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2667 * Fixed some header addition to Toolkit distribution in
2668 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2670 * Added lib/silcclient/client_ops_example.h as an template
2671 file for application programmers to quickly start using
2672 the SilcClientOperation functions in their application.
2673 Updated the lib/silcclient/README as well to tell about this
2674 nice file made available.
2676 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2678 * Call silc_server_remove_from_channels when removing client
2679 entry when NO_SUCH_CLIENT_ID was received. Affected file
2680 is silcd/command_reply.c.
2682 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2684 * Added server & router operator statistics updating. Affected
2685 file silcd/packet_receive.c and silcd/command.c.
2687 * Fixed the SERVER_SIGNOFF notify handling on normal server
2688 not to save the history information for clients. Same was
2689 fixed earlier in remove_clients_by_server function, but not
2690 here. Affected file silcd/packet_receive.c.
2692 * Raised the default connection-retry count from 4 to 7 in
2693 server. Affected file silcd/server.h.
2695 * Cancel any possible reconnect timeouts when we start the
2696 key exchange. Affected file silcd/server.c.
2698 * Do not reconnect on connection failure when SCONNECT was
2699 given. Affected files silcd/server.[ch].
2701 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2703 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2705 * Fixed the NICK command to always give the unformatted
2706 nickname to the one giving the NICK command. If unformatted
2707 nickname is cached already it will be formatted and the
2708 local entry will always get the unformatted nickname.
2709 Affected file lib/silcclient/idlist.c.
2711 * Fixed some double frees from client library commands.
2712 Affected file is lib/silcclient/command.c.
2714 * Fixed CUMODE command in server to assure that no one can
2715 change founder's mode than the founder itself, there was a
2716 little bug. Affected file silcd/command.c.
2718 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2720 * Removed the SilcClientCommandDestructor from the client
2721 libary, it is not needed anymore. Affected files are
2722 lib/silcclient/silcapi.h, command[_reply].[ch],
2723 client_notify, idlist.c.
2725 * Fixed GETKEY command to first resolve client, and then
2726 resolve the server only if the client was not found, instead
2727 of resolving both at the same time. Affected file is
2728 lib/silcclient/command.c.
2730 * Added silc_client_start_key_exchange_cb and lookup the
2731 remote hostname and IP address before starting the key
2732 exchange with server. The affected file is
2733 lib/silcclient/client.c.
2735 * The server's public key is now saved using the IP address
2736 of the server and not the servername for the filename.
2737 The hostname public key filename is checked as an fall back
2738 method if the IP address based filename is not found.
2740 Fixed the GETKEY command to save the fetched server key
2741 in correct filename.
2743 Print the remote server's hostname now when new key is
2744 received during connection process. Affected file is
2745 irssi/src/silc/core/client_ops.c.
2747 * Return always our own public key to the client if it asks
2748 for it with GETKEY command. Affected file silcd/command.c.
2750 * Removed the use_auto_addr variable from default config
2751 file since it was in wrong section. Affected file is
2754 * Fixed TOPIC_CHANGE notification to not route it when it
2755 was sent using silc_server_send_notify_to_channel function.
2756 Affected file silcd/command.c.
2758 * Fixed silc_server_send_notify_kicked to send the kicker's
2759 Client ID also, it was missing. Affected files are
2760 silcd/command.c, silcd/packet_send.[ch].
2762 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2764 * Do not save client history information in SERVER_SIGNOFF.
2765 Fixes the bug in normal server that it does not detect
2766 the client becoming valid after the server becomes back
2767 online. Affected file silcd/server_util.c.
2769 * Added `sock_error' field into the SilcSocketConnection
2770 context. When error occurs during socket operation (read
2771 or write) the error is saved. Added also new function
2772 silc_socket_get_error to return human readable socket error
2773 message. Affected files are lib/silcutil/silcsockconn.[ch],
2774 lib/silcutil/unix/silcunixsockconn.c, and
2775 lib/silcutil/win32/silcwin32sockconn.c.
2777 * The server now prints the socket error message in the
2778 signoff for client. Affected file silcd/server.c.
2780 * Fixed the `created' channel information sending from router
2781 to server in JOIN command. Checks now whether the channel
2782 really was created or not and set it according that.
2784 Fixed the JOIN command to use the client entry's current
2785 ID during the joining procedure instead of the one it sent
2786 in the command (it is checked though), since it can change
2787 between the packet processing and command processing, and
2788 would just case unnecessary pain in the client end. Affected
2789 file silcd/command.c.
2791 * Fixed a channel key payload sending to use correct channel
2792 ID when the server was forced to change the channel's ID by
2793 router. Router sent the key payload with the old Channel ID.
2794 Affected file silcd/packet_receive.c.
2796 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2798 * Call silc_server_save_channel_key only if the key payload
2799 was provided in the JOIN command's command reply. Affected
2800 file silcd/command_reply.c.
2802 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2804 * Fixed silc_mp_sizeinbase to return the value correctly with
2805 MPI. Affected file lib/silcmath/mp_mpi.c.
2807 * Fixed the stop_server signal to correctly stop the scheduler
2808 and gracefully stop the server when SIGTERM or SIGINT signals
2809 are received. Affected file silcd/silcd.c.
2811 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2813 * Simple handling of TERM and HUP signals. Also added some log
2814 flushing call around. Affected file is
2817 * Fixed small bugs in silclog.c. Now buffering output will take
2818 effect after 10 seconds since startup: This will ensure that
2819 no important startup messages are lost. Also output redirection
2820 will preserve original format ([Date] [Type] message).
2821 Affected file is lib/silcutil/silclog.c.
2823 * Added two options to the config file, in the logging section:
2824 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2825 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2827 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2829 * Do not print the warning about log files not being initialized
2830 more than once to avoid excess logging. Affected file is
2831 lib/silcutil/silclog.c.
2833 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2834 the SIM copying in make install in Makefile.am.pre.
2836 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2838 * Rewritten silclog APIs. Globally interesting changes follows:
2839 silc_log_set_files() changed to silc_log_set_file().
2840 silc_log_set_callbacks() changed to silc_log_set_callback().
2841 ROBOdoc documented silclog header file.
2842 SilcLogCb now returns bool to wether inihibit the default
2843 handler or not (to keep the old behaviour return always TRUE).
2844 The new APIs should also fix the problem of the
2845 silcd_error.log file that was written in the current directory.
2848 Log files streams will remain opened after silc_log_set_file()
2849 call, means less CPU usage notably on high traffic servers.
2850 File streams are now full buffered, and flushed to the disk
2851 every 5 minutes, lesses HD activity and CPU usage.
2852 Messages can be redirected, allowing admins to configure
2853 one single logfile for all server messages.
2854 the silc_log_quick global variable to activate fast-logging.
2855 Affected files lib/silcutil/silclog.[ch]
2857 * Changed some code to conform new silclog APIs. Affected
2858 files are doc/example_silcd.conf.in, silcd/server.c
2859 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2862 * Fixed a memory leak that could occur in some situations.
2863 Affected file silcd/serverconfig.c.
2865 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2867 * Added the silc_client_del_client to remove the client from
2868 all channels as well. Affected file lib/silcclient/idlist.c.
2870 * Fixed the client library to correctly remove the client
2871 from all channels when the client entry is being destroyed.
2872 Affected file lib/silcclient/client_notify.c, command.c.
2874 * Added auto-nicking support to the client library. If the
2875 applicatio now sets client->nickname it will be sent to the
2876 server after connecting by the library. This way for example
2877 SILCNICK (or IRCNICK) environment variables will have effect
2878 and always change the nickname automatically to whatever
2879 it is wanted. Affected file lib/silcclient/client.[ch].
2881 * Renamed silc_server_command_bad_chars to the
2882 silc_server_name_bad_chars and moved it to the
2883 silcd/server_util.[ch]. Added also new function
2884 silc_server_name_modify_bad to return nickname that
2885 includes bad characters as new nickname without those
2886 bad characters. This check and modify is now used in
2887 silc_server_new_client when the username is initially set
2888 as nickname, so it must be checked to be valid nickname.
2889 Affected file silcd/packet_receive.c.
2891 * The nickname length is now taken from the packet for real
2892 and not trusted to strlen() since it clearly can return
2893 wrong length for nickname including bad characters. This
2894 also applies to channel names. Affected file silcd/command.c.
2896 * Removed the lib/silcsilm/modules directory. Modules are now
2897 compiled into the lib/silcsim. Fixed the copying of the
2898 modules to follow symbolic links in Makefile.am.pre.
2900 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2902 * Fixed silc_string_regexify list creation. Fixes bugs with
2903 BAN and INVITE commands in server. The affected file is
2904 lib/silcutil/unix/silcunixutil.c.
2906 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2908 * Removed the command destructor entirely from the server's
2909 command and command reply routines. It is not needed, and
2910 its usage was buggy and caused crashes. Affected files are
2911 silcd/command[_reply].[ch].
2913 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2915 * Cancel protocol and NULL sock->protocol if timeout
2916 occurred during protocol. Affected file silcd/server.c.
2918 * Cancel protocol timeouts always before calling the final
2919 callback, to assure that after final callback is called
2920 no other state will be called for the protocol anymore.
2921 Affected file silcd/protocol.c.
2923 * Print error log if incoming connection configuration could
2924 not be found. Affected file silcd/server.c.
2926 * Fixed JOIN command to correctly save the founder mode
2927 to the client on normal SILC server, when the channel
2928 was created by the router. Affected file silcd/command.c.
2930 * Fixed LIST command (hopefully) to send correct reply
2931 packets. Affected file silcd/command.c.
2933 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2935 * The silc_packet_receive_process now returns FALSE if the
2936 read data was invalid packet, and TRUE if it was ok.
2938 The server now checks that if unauthenticated connection
2939 sends data and its processing fails the server will close
2940 the connection since it could be a malicious flooder.
2942 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2944 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2946 * Make sure the warning about error opening a log file is
2947 printed only once and not everytime it fails (produces
2948 too much useless log). Affected file lib/silcutil/silclog.c.
2950 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2952 * Made the silc_server_daemonise() function more readable.
2953 Affected file silcd/server.c.
2955 * Pid file is now optional, the user may comment it out from
2956 the config file. Removed define SILC_SERVER_PID_FILE, we
2957 don't need a default any longer. Affected file
2958 configure.in.pre, lib/Makefile.am.pre.
2960 * Make some use of the pid file. The server now dies at startup
2961 if it detects a valid pid file on his path. The server would
2962 die anyway in this circumstance, because of the bind() failure.
2963 Affected file silcd/silcd.c.
2965 * No longer compiling lib/dotconf.
2967 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2969 * Fixed JOIN command parsing not to crash. Affected file
2970 lib/silcclient/command.c.
2972 * Fied the NICK_CHANGE notify to add the new client entry
2973 even it is resolved. This removes an <[unknown]> nick
2974 thingy bug in the client. Affected file is
2975 lib/silcclient/client_notify.c.
2977 * Do not try to allocate 0 bytes (efence does not like it)
2978 in lib/silccore/silccomand.c when encoding payload.
2980 * Do not take IRCNICK as nickname in Irssi SILC client since
2981 it is not possible to set nickname before hand connecting
2982 the server (TODO has an entry about adding auto-nicking
2985 * Changed the silc_server_command_pending to check whether
2986 there already exists an pending entry with the specified
2987 command, command identifier and pending callback. This is
2988 to fix IDENTIFY and WHOIS related crashes that may register
2989 multiple pending commands with same identifier. Affected
2990 file silcd/command.c.
2992 * Fixed the server to reconnect to the router even if it
2993 was already reconnecting and EOF was received. This to
2994 fix a possibility that the server wouldn't ever try to
2995 auto-reconnect to the router. Affected file silcd/server.c.
2997 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2999 * Fixed the server's password authentication to use the
3000 length of the locally saved password, and not the one
3001 sent in the packet. Affected file silcd/protocol.c.
3003 * Fixed same password authentication problem in the
3004 Authentication Payload handling routines in
3005 lib/silccore/silcauth.c.
3007 * Yet another password authentication problem fixed with
3008 channel password handling in silcd/command.c.
3010 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3012 * If first character of string in silc_parse_userfqdn is '@'
3013 then do not parse it. Affected file is
3014 lib/silcutil/silcutil.c.
3016 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3018 * Fixed minor bug in IDENTIFY command reply sending, which
3019 caused various weird problems during JOIN when it was
3020 resolving names for users. Affected file silcd/command.c.
3022 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3024 * Fixed the IDENTIFY command reply sending to chech better valid
3025 clients. It was possible to send incomplete list of replies.
3026 Affected file silcd/command.c.
3028 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3030 * Added silc_client_command[s]_[un]register functions now to
3031 dynamically register the commands in client library. Removed
3032 the static table of commands. This allows the client library
3033 to call commands without causing the application to know about
3034 what commands library has called.
3036 Removed the INFO command reply kludge to detect when the command
3037 was called by library. Now library use its own command reply
3038 function for INFO command.
3040 Added function silc_client_command_call to call a command.
3041 Application can use it to call command, not access the structure
3044 Now all commands that are sent by the client library (not
3045 explicitly sent by application) use own command reply functions.
3047 Affected files around lib/silcclient/ and in
3048 irssi/src/silc/core/.
3050 * Fixed the WHOIS command reply sending to chech better valid
3051 clients. It was possible to send incomplete list of replies.
3053 Fixed the WHOIS and IDENTIFY to send the request to router
3054 if normal server did not do it and did not find any results.
3056 Affected file silcd/command.c.
3058 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3060 * Moved the internal data from SilcClient context into its
3061 own file, not accesible to application. Affected files
3062 lib/silcclient/client.h and lib/silcclient/client_internal.h,
3063 and other files in client library.
3065 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3067 * Added doc/examples installation target in Makefile.am.pre.
3070 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3072 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
3073 commands the found client entry will be removed from the
3074 cache, after notifying application about the error. Affected
3075 file lib/silcclient/command_reply.c.
3077 * Changed the /MSG to check for exact nickname user gave, and
3078 not let `nick' match `nick@host' if it is only one found. Now,
3079 user must type the exact nickname (like nick@host2) even if
3080 there are no more than one same nicks found. This is to avoid
3081 a possibility of sending nickname to wrong nickname since
3082 `nick' could match `nick@host'. Affected file is
3083 irssi/src/core/silc-servers.c.
3085 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3087 * Do not print "you are now server operator" or similar when
3088 giving /away command. Affected files are
3089 irssi/src/silc/core/client_ops.c, silc-servers.h.
3091 * Made the silc_server_command_pending_error_check to send
3092 the same command reply payload it received back to the
3093 original sender of the command. This way all arguments
3094 that was received by the server will be received by the
3095 client too. Affected file silcd/command.c.
3097 * Added the silc_idcache_add to return the created cache entry
3098 to a pointer. Affected file lib/silccore/silcidcache.[ch].
3100 * Add global clients to expire if they are not on any channel.
3101 This is because normal server will never know if they signoff
3102 if they are not on any channel. The cache expiry will take
3103 case of these entries. This is done by normal servers only.
3104 The affected files are silcd/command_reply.c,
3105 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
3107 * If server receives invalid ID notification for WHOIS or
3108 IDENTIFY and the ID exists in the lists, it is removed.
3109 Affected file silcd/command_reply.c.
3111 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
3112 in client then client entry that it matches is searched and
3113 the nickname is printed on the screen for user. Affected
3114 file irssi/src/silc/core/client_ops.c.
3116 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3118 * Use cache entry expire time in the LIST command reply to
3119 purge old entries from the cache after the LIST command
3120 reply has been received. This way we don't have non-existent
3121 entries in the cache for too long. Affected file is
3122 silcd/command_reply.c.
3124 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3126 * If we are normal server, and we've not resolved client info
3127 in WHOIS or IDENTIFY from router, and it is global client,
3128 we'll check whether it is on some channel. If it is not
3129 then we cannot be sure about its validity and will resolve it
3130 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
3131 file silcd/command.c.
3133 * Search channel by name (if possible) rather than by ID
3134 in IDENTIFY command's command reply. Affected file is
3135 silcd/command_reply.c.
3137 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3139 * Distribute to the channel passphrase in CMODE_CHANGE notify.
3140 Updated specs and implemented it. Affected file silcd/command.c,
3141 silcd/packet_send.c and silcd/packet_receive.c.
3143 * Implemented the <founder auth> payload handling in the JOIN
3144 command. If provided all conditions for channel joining
3145 except requirement to provide correct passphrase can be
3146 overrided by the channel founder. Updated the protocol specs.
3147 Affected file silcd/command.c.
3149 Added support for founder auth in JOIN command in client
3150 library. Fixed the parsing of the JOIN command now to support
3151 all options as they should be. The affected file is
3152 lib/silcclient/command.c.
3154 * Optimized the WHOIS and IDENTIFY commands to send the request
3155 to router only if it includes nicknames or other names. If
3156 they include only IDs then check the local cache first before
3157 routing. Affected file is silcd/command.c.
3159 * Added channels topic announcements. Affected file is
3160 silcd/packet_receive.c and silcd/server.c.
3162 * Fixed the silc_server_send_notify_topic_set to really destine
3163 the packet to channel. Affected file silcd/packet_send.c.
3165 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
3166 library. Affected file lib/silcclient/client_notify.c.
3168 * Added UMODE announcements. Affected file silcd/server.c.
3170 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3172 * Memory leak fixes in:

3179 lib/silccore/silccommand.c
3180 lib/silccore/silcidcache.c
3185 * ROBOdoc documented the lib/silcske/groups.h file and a
3186 bit changed the interface for better.
3188 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3190 * Update the client entry context in the ID cache after
3191 nick change. Affected file lib/silcclient/command.c.
3192 Fixes the CUMODE command when regaining founder privileges,
3193 and a little WHOIS problem.
3195 * Fixed silc_net_gethostbyname to correctly call the
3196 inet_ntop. Affected file lib/silcutil/silcnet.c.
3198 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3200 * Added IPv6 support checking to the configure.in.pre, added
3201 also --enable-ipv6 option to override the check. Affected
3202 file configure.in.pre.
3204 * The silc_thread_create now calls the start function
3205 directly if threads support is not compiled in. Removes
3206 ugly #ifdef's from generic code. Affected files are
3207 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
3209 * Added silc_net_gethostby[name/addr]_async to asynchronously
3210 resolve. Affected files are lib/silcutil/silcnet.[ch].
3212 * Added support for rendering IPv6 based server, client and
3213 channel IDs. Affected file lib/silcutil/silcutil.c.
3215 * Added support for creating IPv6 based server IDs. Affected
3216 file is silcd/serverid.c.
3218 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3220 * Added silc_net_gethostby[addr/name] into the
3221 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
3222 routines. Added silc_net_is_ip[4/6]. Affected file is
3223 lib/silcutil/unix/silcunixnet.c. All routines that take
3224 address as argument now supports both IPv4 and IPv6 addresses.
3226 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3228 * Fixed LIST command reply sending in server. Affected file
3231 * Server now sends the kicker's client ID in the KICK notify
3232 to the kicked client. Affected file silcd/command.c.
3234 * The client library now parses the kickers client ID and
3235 UI displays it. Affected files lib/silcclient/client_notify.c
3236 and irssi/src/silc/core/silc-channels.c, module-formats.c.
3238 * Made all payload parsing function prototypes consistent.
3239 They all take now const unsigned char * and uint32 pair as
3240 the payload data instead of SilcBuffer. Changes all around
3241 the source tree. Other unsigned char* -> const unsigned char*
3242 changes around the tree as well.
3244 * Optimized SFTP client and server packet sending not to
3245 allocate new buffer for each packet but to recycle the
3246 first allocated buffer. Affected files are
3247 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
3249 * Optimized the SFTP client to use SilcList instead of
3250 SilcDList for requests, because it is faster. Affected file
3251 is lib/silcsftp/sftp_client.c.
3253 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
3254 into lib/silccore/silcid.[ch].
3256 Renamed silcpayload.[ch] into silcargument.[ch].
3258 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3260 * If client entry is deleted with active key agreement
3261 session, abort the session.
3263 The silc_client_abort_key_agreement now calls the completion
3264 callback with new SILC_KEY_AGREEMENT_ABORTED status.
3266 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
3269 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3271 * Don't use __restrict in older GCC's. Affected file is
3272 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
3274 * silc_net_localhost now attempts to reverse lookup the
3275 IP/hostname. Affected file lib/silcutil/silcnet.c.
3277 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
3278 command. It can be used to gain founder privileges at
3279 the same time when joining the channel.
3281 Defined that the SILC_NOTIFY_TYPE_KICKED send the
3282 kicker's client ID as well. Updated protocol specs.
3284 Defined that the server must send SILC_COMMAND_IDENTIFY
3285 command reply with error status to client who sent
3286 private message with invalid client ID.
3288 Updated the protocol specification.
3290 * Added silc_server_send_command_reply to send any
3291 command reply. Affected file silcd/packet_send.[ch].
3293 * Added silc_id_payload_encode_data to encode ID payload
3294 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
3296 * The server now send IDENTIFY command reply with error
3297 status if client ID in private message is invalid. Affected
3298 file silcd/packet_receive.c.
3300 * Save the server key file with server's IP address in
3301 the filename instead of hostname. The affected file is
3302 irssi/src/silc/core/client_ops.c.
3304 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3306 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
3309 * Added libtool support for compiling shared objects in
3310 lib/silcsim. Affected file configure.in.pre and
3311 lib/silcsim/Makefile.am. Original patch by cras.
3313 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3315 * Pid file configuration, and server's config file fixes
3316 patch by toma. Updated CREDITS file.
3318 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3320 * Fixed silc_client_channel_message to not try to decrypt
3321 the message twice if it resolved the destination client
3322 information. This could cause of dropping one channel
3323 message. Affected file lib/silcclient/client_channel.c.
3325 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3327 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3328 lib/silcclient/client.c. This function is used when the SILC
3329 Client is run under some other scheduler, or event loop or
3330 main loop. On GUI applications, for example this may be
3331 desired to used to run the client under the GUI application's
3332 main loop. Typically the GUI application would register an
3333 idle task that calls this function multiple times in a second
3334 to quickly process the SILC specific data.
3336 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3338 * Fixed silc_server_drop() for dropping the supplementary
3339 groups as well, this could cause a security hole on some
3342 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3344 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
3347 * Write PID file after dropping privileges. Added -F option
3348 to run server on foreground. A patch by debolaz.
3349 Affected files silcd/server.c, silcd/silcd.c.
3351 * Fixed MOTD to return the MOTD file server name. Affected
3352 file silcd/command.c.
3354 * Added INFO command reply handling to the Irssi SILC Client.
3355 Affected file irssi/src/silc/core/client_ops.c.
3357 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3359 * Fixed the silc_idcache_list_* routines to really support
3360 the dynamic list. Fixes a crash. Affected file is
3361 lib/silccore/silcidcache.c.
3363 * Fixed the LIST command reply to really call LIST command's
3364 pending callbacks. Affected file silcd/command_reply.c.
3366 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3368 * Update conn->local_entry->nickname after giving NICK
3369 command. Affected file lib/silcclient/command.c.
3371 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3373 * Added the [pid] option to the silcd configuration file
3375 Affected files: serverconfig.[ch] and silcd.c
3377 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3379 * Save fingerprint in WHOIS command reply in server.
3380 Affected file silcd/command_reply.c.
3382 * Fixed NICK commands pending callback registration.
3383 Affected file lib/silcclient/command.c.
3385 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3387 * Use ++server->cmd_ident when sending commands in server,
3388 instead of random number. Affected file silcd/command.c.
3390 * Fixed GETKEY command reply to call actually GETKEY pending
3391 command callbacks. Affected file silcd/command_reply.c.
3393 * A bit stricter check for nicknames. Check for same nickname
3394 in NICK command also. Affected file silcd/command.c.
3396 * Do not call INFO command everytime client ID changes, only
3397 during first connecting. Affected file lib/silcclient/client.c.
3399 * Set the new nickname only after successful command reply for
3400 NICK command is returned by server. Affected file
3401 lib/silcclient/command.c.
3403 * Remove nicknames from nicklist during server_signoff notify.
3404 Should fix /NAMES bit more. The affected file is
3405 irssi/src/silc/core/silc-channels.c.
3407 * Added `fingerprint' field to the SilcIDListData in the
3408 silcd/idlist.h to hold the fingerprint of the client's
3411 Send the fingerprint of the client's public key in WHOIS
3414 Affected files silcd/command.c, and silcd/idlist.[ch].
3416 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3417 create fingerprint from given data.
3419 * Show the fingerprint of the client's public key in WHOIS.
3420 Affected files irssi/src/module-formats.[ch] and
3421 irssi/src/silc/core/client_ops.c.
3423 * Format the multiple same nicknames also during JOIN and
3424 NICK_CHANGE notifys. Affected file is
3425 lib/silcclient/client_notify.c.
3427 * Do not print error on screen for invalid private message
3428 payload since it can come if someone is sending private
3429 messages with wrong key. Affected file
3430 lib/silccore/silcprivate.c.
3432 * Fixed multiple concurrent /PING crash. Affected file
3433 lib/silcclient/command.c.
3435 * Changed the wrong ID encoding. All IP addresses must be
3436 in MSB first order in encoded format. They were encoded
3437 wrong and was in LSB format. Affected files are
3438 silcd/serverid.c, lib/silcutil/silcutil.c.
3440 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3442 * Call the `connect' client operation through the scheduler
3443 in case of error. Affected file lib/silcclient/client.c.
3445 * Call the `failure' client operation even if the error
3446 occurred locally during a protocol. Affected file is
3447 lib/silcclient/protocol.c.
3449 * Added support of sending LIST command to router from normal
3450 server. This way normal server can get list of all channels
3451 in the network too. Fixed the channel list sending in the
3452 server too. Affected files are silcd/command.c, and
3453 silcd/command_reply.[ch].
3455 * Added silc_server_update_channels_by_server and
3456 silc_server_remove_channels_by_server. They are used during
3457 disconnection of primary router and in backup router protocol.
3458 Affected file silcd/server_util.[ch], silcd/server.c and
3459 silcd/server_backup.c.
3461 * Fixed channel adding to global list in IDENTIFY command
3462 reply in server. Affected file silcd/command_reply.c.
3464 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3466 * If the incoming packet type is REKEY or REKEY_DONE process
3467 that packet always synchronously. Fixes yet another MAC
3468 failed error on slow (dialup) connections. Affected file
3469 lib/silcclient/client.c and silcd/server.c.
3471 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3473 * Call check_version SKE callback for initiator too. Affected
3474 file lib/silcske/silcske.c.
3476 * Implemented fix for security hole found in the SKE that was
3477 fixed in the specification few days back; the initiator's
3478 public key is now added to the HASH value computation.
3479 Added backwards support for the old way of doing it too, for
3480 old clients and old servers. Affected file is
3481 lib/silcske/silcske.c.
3483 * Enabled mutual authentication by default in SKE. If initiator
3484 is not providing mutual authentication the responder will
3485 force it. This will provide the proof of posession of the
3486 private key for responder. The affected files are
3487 lib/silcclient/protocol.c and silcd/protocol.c.
3489 * Do not cache anymore the server's public key during SKE.
3490 We do mutual authentication so the proof of posession of
3491 private key is done, and if the server is authenticated in
3492 conn auth protocol with public key we must have the public
3493 key already. Affected file silcd/protocol.c.
3495 * Added new global debug variable: silc_debug_hexdump. If
3496 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3497 file lib/silcutil/silclog.[ch].
3499 * Fixed compilation warning due to char * -> const char *.
3500 Affected files lib/silcutil/silcnet.h, and
3501 lib/silccore/silcauth.[ch].
3503 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3505 * Fixed CMODE command when new channel key was created. If
3506 the creation failed the old key was removed. Next time giving
3507 same command would crash the server since the old key was
3508 freed already. Affected file silcd/command.c.
3510 * Fixed the silc_server_announce_get_channels to not crash
3511 on reconnect. Affected file silcd/server.c.
3513 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3515 * Added silc_log_set_debug_string function to set a regex
3516 string to match for debug output. Only the function names,
3517 or filenames matching the given debug string is actually
3518 printed. This way it is possible to filter out those debug
3519 strings that user is not interested in.
3521 Fixed a bug in silc_string_regexify.
3523 Affected files lib/silcutil/silclog.[ch], and
3524 lib/silcutil/unix/silcunixutil.c.
3526 * Changed the -d options in both server and Irssi SILC client
3527 to take the debug string as argument. Affected files
3528 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3530 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3532 * Added silc_hash_babbleprint to create a Bubble Babble
3533 Encoded fingerprint. The encoding is developed by Antti
3534 Huima (draft-huima-babble-01.txt), and it creates human
3535 readable strings out of binary data. Affected file
3536 lib/silccrypt/silchash.[ch].
3538 * Print the babble print now in addition of fingerprint as well
3539 in Irssi SILC client. Affected files are
3540 irssi/src/fe-common/silc/module-formats.[ch],
3541 irssi/src/fe-common/silc/core/client_ops.c.
3543 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3545 * Fixed a security problem found in SKE. The initiator's
3546 public key too is now added to the HASH hash value creation
3547 which is signed by the responder to create the SIGN value.
3548 This will prevent anyone in the middle to lie to the responder
3549 about the initiator's public key. If this is done now, the
3550 man in the middle will get caught. Updated the protocol
3553 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3555 * Better installation directory handling. Configure module
3556 paths and other paths automatically to example_silc* files
3557 in doc/. A patch by toma.
3559 * Fixed compiler warning from MPI library, and from SILC RNG.
3562 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3563 It can be configured with ./configure. A patch by toma.
3565 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3567 * Find correct make to use in prepare-clean. A patch by
3568 toma. Affected file prepare-clean.
3570 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3572 * Added irssi variables use_auto_addr, auto_bind_ip,
3573 auto_bind_port and auto_public_ip.
3575 * Changed the interface for silc_client_send_key_agreement
3576 in lib/silcclient/silcapi.h
3580 irssi/src/silc/core/silc-core.c
3582 lib/silcclient/silcapi.h
3583 irssi/src/silc/core/silc-channels.c
3584 lib/silcclient/client_keyagr.c
3587 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3589 * Added silc_pkcs_public_key_compare to compare two
3590 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3592 * Check that the client who set the founder mode on the
3593 channel is the same client that is giving the founder
3594 mode to itself. It is done by comparing the saved public
3595 key (it is saved even in the authentication is passphrase).
3596 Affected file silcd/command.c.
3598 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3600 * Do not process packet for disconnected socket connection.
3601 Affected file lib/silccore/silcpacket.c.
3603 * Process the DISCONNECT packet through scheduler in the
3604 client library. Affected file lib/silcclient/client.c.
3606 * Fixed the silc_client_packet_parse to not to increase
3607 the packet sequence number if the conn->sock and the
3608 current socket connection is not same. This can happen
3609 for example during key agreement when the conn includes
3610 multiple socket connections (listeners). Affected file
3611 lib/silcclient/client.c.
3613 * The sender of the file transfer request now provides also
3614 the pointer (listener) for the key exchange protocol. If
3615 the listener cannot be created then it sends empty key
3616 agreement and lets the receiver provide the listener.
3618 Added `local_ip' and `local_port' arguments to the
3619 silc_client_file_send. If they are provided they are used,
3620 if not then it will attempt to find local IP address, if
3621 not found or bind fails then the remote client will provide
3624 Affected files are lib/silcclient/client_ftp.c and
3625 lib/silcclient/silcapi.h.
3627 * Extended the FILE SEND command to support defining the
3628 local IP and port for key exchange listener. They are
3629 optional. Affected file irssi/src/silc/core/silc-servers.c.
3631 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3633 * Defined to WHOIS command reply the sending of fingerprint
3634 of the client's public key (if the proof of posession of the
3635 corresponding private key is verified by the server).
3636 Updated to the protocol specification.
3638 * Added support of receiving the client's public key's
3639 fingerprint in command reply in client library. Affected
3640 file is lib/silcclient/command_reply.c, and
3641 lib/silcclient/idlist.[ch].
3643 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3645 * Do not send over 128 chars long nickname to the server
3646 in NICK command. Affected file lib/silcclient/command.c.
3648 * Do not send over 256 chars long channel names to the server
3649 in JOIN command. Affected file lib/silcclient/command.c.
3651 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3653 * Assure that silc_server_close_connection cannot be called
3654 twice for same socket context. Affected file is
3657 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3659 * Send error message to application if opening file for
3660 writing during file transfer fails. Affected file is
3661 lib/silcclient/client_ftp.c.
3663 Remove all file transfer sessions for a client that we're
3664 removing from ID cache.
3666 Affected file is lib/silcclient/client_ftp.c.

3696 client library. Affected file lib/silcclient/client_prvmsg.c.
3698 * Do not actually remove the client directly from ID cache
3699 during SERVER_SIGNOFF, but invalidate it. This way we
3700 preserve the WHOWAS info for the client. Affected file
3701 silcd/server_util.c.
3703 * Fixed SERVER_SIGNOFF notify handling in the server. The
3704 server is now able to process incoming SERVER_SIGNOFF notify
3705 for a server that it doesn't even know about. It will remove
3706 the clients provided in the notify. Affected file
3707 silcd/packet_receive.c.
3709 * Check for partial packet in data queue after every packet that
3710 was found from the queue. Return and wait for more data if
3711 there is partial data in queue. Affected file is
3712 lib/silccore/silcpacket.c.
3714 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

3722 * Check that newsize in silc_buffer_realloc is larger than
3723 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3725 * Added better monitor of file transfers. It now monitors
3726 key agreement protocol during the file transfer too. Added
3727 error reporting too. Affected files
3728 irssi/src/silc/core/silc-servers.c,
3729 irssi/src/fe-common/silc/module-formats.[ch].
3731 * Wrote a help file for FILE command.
3733 * Added silc_rng_global_get_byte_fast to get not-so-secure
3734 random data as fast as possible. Random data is read from
3735 /dev/urandom if available and from the SILC RNG if not
3736 available. It is used in padding generation. Affected file
3737 lib/silccrypt/silcrng.[ch].
3739 * All packets in client library are now processed synchronously.
3740 Optimized packet processing a lot. Affected file
3741 lib/silcclient/client.c.
3743 * All server connection packets are processing synchronously
3744 now in server, to optimize packet processing. Affected file
3747 * Include files are installed now only in Toolkit distribution
3748 if make install is given. Affected files: all Makefile.am's.
3750 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3752 * Assure that silc_client_notify_by_server_resolve does not
3753 resolve the client information multiple times. If it cannot
3754 be found by the first it cannot be found at all. Affected
3755 file lib/silcclient/client_notify.c.
3757 * Fixed WHOWAS command reply calling. Affected file
3758 lib/silcclient/command_reply.c.
3760 * Removed all references to silc_idlist_get_client from the
3761 Irssi SILC client since that call is internal call used by
3762 the library. The Irssi SILC client will use now client
3763 retrieval functions found in silcapi.h.
3765 * Fixed a bug in resolving nickname info before sending
3766 private message. It used freed memory. Affected file
3767 irssi/src/silc/core/silc-servers.c.
3769 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3771 * Assure my_channels statistics cannot go negative in server.
3772 Affected files silcd/server.c, silcd/server_util.c.
3774 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3788 * Added silc_net_localip to return local host's IP address.
3789 Affected file lib/silcutil/silcnet.[ch].
3791 * If key exchange or rekey protocol is active for a connection
3792 parse all packets syncronously since there might be packets
3793 in packet queue that we are not able to process without first
3794 processing packets before them. Affected file silcd/server,
3795 lib/silcclient/client.c.
3797 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3798 whether library should continue processing the packet.
3799 Affected file lib/silccore/silcpacket.h.

3830 lib/silcutil/silcutil.[ch].
3832 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3834 * Resolve the client info when received private message or
3835 channel message for a client which nickname we don't know.
3836 Affected files lib/silcclient/client_prvmsg.c and
3837 lib/silcclient/client_channel.c.

3840 file irssi/src/silc/core/silc-channels.c.
3842 * Added SilcClientStatus field to the SilcClientEntry in the
3843 lib/silcclient/idlist.h.
3845 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3846 is incomplete and is being resolved, it won't be resolved
3849 Make sure also that USERS command reply does not resolve
3850 twice information. Affected file is
3851 lib/silcclient/command_reply.c.
3853 Make sure that silc_client_get_clients_by_list does not
3854 resolve twice same information.
3856 * Check for valid client->id in the silc_server_free_client_data.
3857 Affected file silcd/server.c.
3859 * Fixed /GETKEY nick@server not to crash if the server entry
3860 is not found. Affected file lib/silcclient/command.c.
3862 * Fixed the silc_server_check_cmode_rights to check the
3863 requested modes correctly. Affected file silcd/command.c.

3868 Affected file silcd/command.c.
3870 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3872 * Call the silc_server_udpate_servers_by_server in the
3873 primary router that comes back online in the backup resuming
3874 protocol. Otherwise it routes packets wrong. Affected file
3875 silcd/server_util.[ch], silcd/server_backup.c.
3877 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3879 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3880 lib/silcutil/silcbuffmt.[ch].
3882 * Redefined the SILC packet header to include the padding
3883 length. Affected file lib/silccore/silcpacket.[ch].
3885 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3886 length for maximum padding up to 128 bytes). Affected
3887 file lib/silccore/silcpacket.h.
3889 * Removed all backwards support for old 0.5.x MAC thingies.
3890 The SILC packet header change makes it impossible to be
3891 backwards compatible.
3893 * Send the ENDING packet with timeout in the backup resuming
3894 protocol. This is to assure that all routers has connected
3895 to the primary router. Affected file silcd/server_backup.c.
3897 * Changed the RNG to take the first IV from random data. It
3898 used to take it from zero actually. Changed the RNG also
3899 to use /dev/urandom during session. /dev/random is used
3900 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3902 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3904 * Changed the SILC packet header to have the first two bytes
3905 (the packet length) encrypted. Affected files aroung the
3906 code tree, lib/silccore/silcpacket.[ch]. Removed the
3907 SilcPacketCheckDecrypt callback. It is not needed anymore
3908 since the silc_packet_receive_process will determine now
3909 whether the packet is normal or special.
3911 * Implemented the unidirectional MAC keys. Affected files
3912 lib/silcske/silcske.c, silcd/protocol.c and
3913 lib/silcclient/protocol.c.
3915 * Implemented the packet sequence number to the MAC computation.
3916 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3917 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3918 lib/silcclient/protocol.c.
3920 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3922 * Allow backup router to announce servers. All servers
3923 announced by backup router are added to the global list
3924 automatically. Update hte server's socket to our primary
3925 router also when backup router announces a server.
3926 Affected file silcd/packet_receive.c.
3928 * Do not update the client->router in the function
3929 silc_server_udpate_clients_by_server if the client is on
3930 global list. We might fail to find any specific server
3931 for locally connected clients and local cell clients. They
3932 should still use the `from' and not `to' as client->router.
3933 This fixes backup router resuming protocol. Affected file
3934 silcd/server_util.c.
3936 * Decrease channel statistics count only if the channel
3937 deletion worked. Affected files are silcd/server.c and
3938 silcd/server_util.c.
3940 * Added silc_server_update_servers_by_server to update origin
3941 of all server entries. Used during backup router protocol.
3942 Affected files silcd/server_util.[ch], silcd/server.c. and
3943 silcd/backup_router.c.
3945 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3946 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3947 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3948 lib/silccrypt/silchmac.c.
3950 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3952 * Assure that router cannot reroute the same channel message
3953 to the sender. Affected file silcd/packet_receive.c.
3955 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3957 * Made better checks that the channel message is not sent
3958 to the router it came from. Affected file is
3959 silcd/packet_send.c. Fixed memory leak too.
3961 * Announce informations for incoming router connection, but
3962 only after checking if it is replaced by backup router.
3963 Affected file silcd/packet_receive.c.
3965 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3967 * Fixed the backup resuming protocol to work in multiple
3968 router environment. Affected file silcd/server_backup.c.
3970 * Route packet only to one router in the function
3971 silc_server_packet_send_to_channel. Affected file is
3972 silcd/packet_send.c.
3974 * Fixed silc_server_send_notify_dest to set the broadcast
3975 flag. Fixed the silc_server_send_notify_topic to actually
3976 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3977 Affected file silcd/packet_send.c.
3979 * Changed the SFTP Filesystem interface. Changed the
3980 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3981 the filesystem operation function. The SilcSFTPFilesystem
3982 is now a context that is allocated by all filesystem allocation
3983 functions and it already includes the operations structure
3984 and filesystem specific context. It is given as argument
3985 now to the silc_sftp_server_start. This made the interface
3986 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3987 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3989 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3991 * Changed the backup router adding and getting interfaces
3992 in the server. The router that will be replaced by the
3993 specified backup router is now sent as argument. Affected
3994 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3997 * Added silc_net_addr2bin_ne to return the binary form of
3998 the IP address in network byte order. Affected files
3999 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
4001 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4003 * Check for existing server ID in silc_server_new_server
4004 and in silc_server_connect_to_router_final and remove the
4005 old entry if it exists. Affected file silcd/packet_receive.c,
4008 * Send the channel message always to only one router, either
4009 in upstream or downstream. Affected file is
4010 silcd/packet_send.c.
4012 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4014 * Wrote the definition of the backup resuming protocol to the
4015 protocol specification.
4017 * Removed one redundant channel key generation from normal
4018 server during joining procedure. Removed one redundant
4019 channel key sending from server to router during joining
4020 procedure. Affected file silcd/command.c.
4022 * Made minor bugfixes to the backup router resuming protocol.
4023 Affected file silcd/server_backup.c, server.c.
4025 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4027 * Added --disable-asm configuration option. Affected files
4028 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
4031 * Implemented the backup resuming protocol that is used to
4032 resume the primary router position in the cell after the
4033 primary router comes back online. Affected files
4034 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
4035 and silcd/server_util.[ch].
4037 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4039 * Sleep two (2) seconds after sending QUIT command to server.
4040 Affected file lib/silcclient/command.c.
4042 * Assure that if outgoing data buffer is pending do not force
4043 send any data. Affected file silcd/packet_send.c.
4045 * Assure that if outgoing data buffer is pending do not force
4046 send any data. Affected file lib/silcclient/client.c.
4048 * Implemented the backup router support when the primary router
4049 goes down. The servers and routers can now use the backup
4050 router as new primary router without loosing connectivity.
4052 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4054 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
4055 in the server to indicate disabled entry. All data read
4056 from the connection will be ignored and no data is sent
4057 for entry that is disabled. Affected files are
4058 silcd/idlist.h, silcd/server.c.
4060 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4062 * Created SFTP client and server test programs in the
4063 lib/silcsftp/tests directory.
4065 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4067 * Implemented memory filesystem (virtual filesystem) for
4068 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
4071 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4073 * Implemented the SFTP (SSH File Transfer Protocol) to the
4074 lib/silcsftp. It includes SFTP client and SFTP server
4077 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4079 * Moved lib/silccore/silcprotocol.[ch] to the
4080 lib/silcutil library.
4082 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
4083 take variable argument list pointer as argument. Affected
4084 file lib/silcutil/silcbuffmt.[ch].
4086 * Added silc_buffer_set function that is used to set data
4087 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
4088 Affected file lib/silcutil/silcbuffer.h.
4090 * Changed various routines in the core library to use the new
4091 silc_buffer_set instead of allocating new buffer only for
4094 * Added 64-bit value formatting and unformatting support to the
4095 silc_buffer_[un]format routines. Affected file is
4096 lib/silcutil/silcbuffmt.[ch].
4098 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
4099 to includes/bitmove.h.
4101 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4103 * Fixed channel user mode saving in client library. Affected
4104 file lib/silcclient/command[_reply].c.
4106 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4108 * Defined the file transfer to the SILC Protocol. Added
4109 new packet type SILC_PACKET_FTP and defined File Transfer
4110 Payload. The mandatory file transfer protocol is SFTP
4111 (SSH File Transfer Protocol). Affected file in addition
4112 of the internet draft is lib/silccore/silcpacket.h.
4114 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
4115 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
4116 is used as part of backup router protocol when the primary
4117 router of the cell is back online and wishes to resume
4118 the position as primary router.
4120 * Redefined the MAC generation keys in the protocol. The
4121 same key is not used anymore in both direction. Both
4122 direction will now use different keys for sending and
4123 receiving. This fixes a potential security flaw. This
4124 change causes incompatibilities in the protocol.
4126 * Redefined also the MAC computation from the packet.
4127 An packet sequence number is now added to the MAC
4128 computation. This prevents possible replay attacks against
4129 the protocol. This change too causes incompatibilities
4132 Added `sequence' field to the SilcPacketContext to hold
4133 the current sequence number for the packet.
4135 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4137 * Added `created' field to the SilcIDListData in the file
4138 silcd/idlist.h to indicate the time when the entry was
4141 * Added `created' field to the SilcChannelEntry too. Affected
4142 file silcd/idlist.h.
4144 * Added `creation_time' aguments to all the announcement functions
4145 in the server. If it is provided then only the entries that
4146 was created after the provided time frame are actually
4147 announced. Affected file silcd/server.[ch].
4149 * The protocol says that the Channel ID's IP address must be
4150 based on the router's IP address. Added check for this in
4151 the silc_server_new_channel when processing incoming New Channel
4152 Payload. Affected file silcd/packet_receive.c.
4154 * Print out the correct version with --version in SILC client.
4155 Affected file irssi/src/silc/core/silc-core.c.
4157 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4159 * Fixed WHOWAS command to check for completnes of the client
4160 entry always, not just when the command is coming from client.
4161 Affected file silcd/command.c.
4163 * Added new function silc_server_packet_queue_purge to purge the
4164 outgoing data queue to the network. After the function returns
4165 it is guaranteed that the outgoing packet queue is empty.
4166 Affected file silcd/packet_send.[ch].
4168 * Purge the outgoing packet queue in the rekey protocol's final
4169 callback to assure that all rekey packets go to the network
4170 before quitting the protocol. Affected file silcd/server.c.
4172 * Added silc_client_packet_queue_parse as similar function as
4173 in server to the client library. The affected file is
4174 lib/silcclient/client.c.
4176 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4178 * Splitted silcd/server.c and created silcd/server_util.[ch]
4179 for utility functions.
4181 * Added new socket flag SILC_SF_DISABLED to indicate that the
4182 connection is open but nothing can be sent to or received from
4183 the connection. Affected file lib/silcutil/silsockconn.[ch].
4184 The checking for disabled socket is checked in the low level
4185 silc_socket_write and silc_socket_read functions.
4187 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4189 * Allow only nicknames and channel names that fits into the
4190 7-bit unsigned char ASCII set. Affected file silcd/command.c.
4192 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4194 * When processing JOIN command reply in server check that if
4195 the channel exists in our global list we'll move it the local
4196 list. Affected file silcd/command_reply.c.
4198 * Fixed the check whether client is joined on the channel already
4199 in JOIN command. Affected file lib/silcclient/command.c.
4201 * Fixed the JOIN command reply to check whether the channel
4202 already exists. Affected file lib/silcclient/command_reply.c.
4204 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4206 * Added silc_ske_status_string to map the SKE error numbers
4207 to readable strings. The affected files are
4208 lib/silcske/silcske[_status].[ch].
4210 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4212 * Do not show the private channels on the WHOIS channel list
4213 as it is not allowed by the protocol. The affected file is
4216 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4218 * Assure that the packet length digged from the actual packet
4219 is something sensible in the silc_packet_decrypt_rest_special
4220 in lib/silccrypt/silcpacket.c.
4222 * Free and NULL the allocated pointer in silc_hmac_alloc if
4223 the HMAC allocation fails. The affected file is
4224 lib/silccrypt/silchmac.c.
4226 * Print the selected security properties to the log files in
4227 the server. Affected file silcd/protocol.c.
4229 * Add SKE's reference counter even if calling the completion
4230 callback manually. Otherwise it goes negative, although it
4231 does not cause any problems. The affected file is
4232 lib/silcske/silcske.c.
4234 * Remove the client entry with short timeout after giving the
4235 KILL command. Affected file lib/silcclient/command.c.
4237 * Fixed to send error reply in WHOIS and IDENTIFY commands in
4238 case all found clients are already disconnected (WHOWAS would
4239 found them) in the server. Affected file silcd/command.c.
4241 * Update the last_receive (time of last data received) to be
4242 updated only when received private or channel message so that
4243 the idle time showed in WHOIS makes more sense.
4245 * Added boolean field `valid' in to the SilcClientEntry in the
4246 client library to indicate whether the entry is valid or not.
4247 This fixes the nickname change bug on channel when changing
4248 the nickname to be same than the old (like nick to Nick) the
4249 nickname formatter doesn't set the new nick anymore to Nick@host.
4250 Affected file lib/silcclient/idlist.[ch].
4252 * Now actually fixed the nickname changing on disconnection.
4253 Added new function silc_change_nick to the Irssi SILC Client.
4254 Affected file irssi/src/silc/core/client_ops.c,
4255 irssi/src/silc/core/silc-nicklist.[ch].
4257 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4259 * Check that the public key exists in the GETKEY command before
4260 trying to encode it. Affected file silcd/command.c.
4262 * Print some notifications on received public keys with GETKEY
4263 command in the Irssi SILC Client. Affected files are
4264 irssi/src/fe-common/silc/module-formats.[ch],
4265 irssi/src/silc/core/client_ops.c.
4267 * Use IDENTIFY command to resolve the server information in the
4268 GETKEY command instead of INFO command. Affected file
4269 lib/silcclient/command.c.
4271 * All command reply functions in the client library now calls
4272 the pending command reply callbacks even if an error has
4273 occurred. The server has done this a long time and now it was
4274 time to move the client library to this as well. Now all
4275 errors can be delivered back to the pending command reply
4276 callbacks if necessary. Affected files are
4277 lib/silcclient/command[_reply].[ch].
4279 * Change the nickname on disconnection back to the username
4280 because in reconnect the server will enforce it to it anyway.
4281 Affected file irssi/src/silc/core/silc-servers.c.
4283 * Fixed a config file parsing bug in the Irssi SILC client.
4284 Affected file irssi/src/silc/core/clientconfig.c.
4286 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4288 * When printing the channel mode on JOIN, verify that the
4289 channel key and channel's HMAC are valid. Affected file
4290 irssi/src/silc/core/client_ops.c.
4292 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4294 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
4295 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
4296 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
4298 * Removed channel key rekey task deleting from the function
4299 silc_server_save_channel_key. Affected file silcd/server.c.
4300 Added explicit timeout task context instead that is used to
4301 delete the task if we are registering a new task before the
4302 new task has elapsed.
4304 * When channel key rekey occurs the client library now saves
4305 the old channel key for a short period of time (10 seconds) and
4306 is able to use it in case some is still sending channel
4307 messages encrypted with the old key after the rekey. Affected
4308 file lib/silcclient/[idlist.h|client_channel.c].
4310 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4312 * Added check to the silc_server_new_id_real to not accept
4313 new ID if it is the sender's own ID. Affected file is
4314 silcd/packet_receive.c.
4316 * Assure that we do not announce ourself or the one we've
4317 sending our announcements when we're router and are announcing
4318 servers to our primary router. Affected file silcd/server.c.
4320 * Fixed silc_server_command_identify_check_client to assemble
4321 correct WHOIS packet. It send corrupted WHOIS packet and
4322 caused problem with router to router connections. Affected
4323 file silcd/command.c.
4325 Fixed also silc_server_command_whois_check the same way
4326 as for the IDENTIFY command.
4328 * Added new SilcIDListStatus to the server in the SilcIDListData
4329 structure. The status now includes the current status of
4330 the entry (like registered, resolved etc.). Affected file
4331 silcd/idlist.[ch]. Defined a bunch of different status types
4332 as well. This replaced the old boolean registered field as well.
4334 Added resolve_cmd_ident field to the SilcClientEntry structure
4335 too so that if the entry is for example being resolved so
4336 another command may attach to the same pending command reply
4337 without requiring to resolve the same entry again. This concept
4338 should optimize the WHOIS and the IDENTIFY resolving under
4339 heavy load by taking away unnecessary resolving for entries
4340 that are being resolved already.
4342 Added support for adding multiple pending commands for one
4343 command idenfier. Affected file silcd/command[_reply].[ch].
4345 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4346 before deleting the data. Otherwise the hash table will have
4347 freed data in comparison functions. Affected file is
4348 silcd/command_reply.c.
4350 * Fixed silc_idlist_replace_client_id to add the new entry to
4351 the cache with NULL nickname. Otherwise there will be invalid
4352 memory as the nickname after the nickname is freed. Affected
4353 file silcd/packet_receive.c.
4355 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4356 saved into wrong slots because the previous number of entries
4357 was not taken into account. Affected file silcd/idlist.c.
4358 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4360 * If we are router and we receive JOIN notify to a channel that
4361 does not have any users then notified client is marked as the
4362 channel founder, as it is it. The affected file is
4363 silcd/packet_receive.c
4365 * Added to the extended hash table API's table_del_*ext functions
4366 the destructor as argument too, so that the caller can decide
4367 which destructor to use or whether to use destructor at all.
4368 Affected file lib/silcutil/silchashtable.[ch].
4370 * Fixed ID Cache purging. It actually deleted the entries from
4371 the hash table after the data was freed. The hash table ended
4372 up comparing freed memory. The affected file is
4373 lib/silccore/silcidcache.c.
4375 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4377 * Fixed Irssi SILC client's KILL command's HELP syntax.
4379 * The USERS command now resolves the detailed user information
4380 if the userinfo field is missing. Affected file is
4381 lib/silcclient/command_reply.c.
4383 * Do not print error in silc_file_read if the read file does
4384 not exist. Just silently return NULL. Affected file is
4385 lib/silcutil/silcutil.c.
4387 * Fixed the silc_log_output to not wine about NULL filename
4388 and to not create some bogus " " filename. Affected file is
4389 lib/silcutil/silclog.c.
4391 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4393 * Fixed various printing bugs on the user interface in the
4394 Irssi SILC Client. Minor changes that were forgotten from
4397 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4399 * Fixed the configure.in.pre and the compilation and distribution
4400 environment to support the new autoconf 2.52. That version is
4401 now required to compile the CVS trunk.
4403 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4405 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4406 to generally parse user@fqdn format strings. Affected file
4407 lib/silcutil/silcutil.c.
4409 * Added nickname_format and nickname_force_format fields to the
4410 SilcClientParams structure. The first one defines the format
4411 for the nicknames that the library will enforce if the receives
4412 multiple same nicknames. The second one is boolean value and
4413 can be used to force the library to always enforce the format
4414 to the nicknames regardles whether there are multiple nicknames
4415 or not. This configurable formatting was employed to flexibly
4416 support accessing multiple nicknames from the user interface.
4417 The userinterface can now set the nicknames to what ever format
4418 they prefer. Affected file lib/silcclient/silcapi.h.
4420 Added function silc_client_nickname_format to the file
4421 lib/silcclient/idlist.c. It performs the nickname formatting.
4423 Added new field `hostname´ to the SilcClientEntry context.
4424 It holds the hostname of the client. Affected file is
4425 lib/silcclient/idlist.h.
4427 * Irssi SILC Client sets the nicknames in nick@hostn format.
4428 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4429 irssi/src/silc/core/silc-core.c.
4431 The WHOIS printing now also shows both the real nickname and
4432 the formatted nickname so that user knows how to access the
4433 user if there are multiple same nicknames cached. Affected
4434 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4435 printing formatting too to take the hostname now as a separate
4436 argument. The Affected file is
4437 irssi/src/fe-common/silc/modules-formats.[ch].
4439 * Changed the silc_client_get_clients_local to accept the formatted
4440 nickname as argument. It accepts the real nickname too but the
4441 formatted nickname can be used to find the true entry from
4442 multiple entries. Affected file lib/silcclient/silcapi.h and
4443 lib/silcclient/idlist.c.
4445 * Added nickname_format_parse field to the SilcClientParams.
4446 It is a callback function provided by the application to parse
4447 the nickname out of the formatted nickname string. The library
4448 calls it to get the nickname from the formatted string. Since
4449 the application generally knows better the format of the nickname
4450 string it parses it instead of the library, even though library
4451 encodes the formatted string. If the callback function is not
4452 provided then the library will use the string as is. The
4453 affected file is lib/silcclient/silcapi.h.
4455 * All the nickname strings passed to the client library in
4456 commands are now expected to be formatted nickname strings.
4457 If the command does not support the formatted nickname string
4458 it will assume that the sent string is the actual nickname.
4459 Affected file lib/silcclient/command.c.
4461 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4463 * Added public key authentication support to OPER and SILCOPER
4464 commands in the client library. Affected file is
4465 lib/silcclient/command.c.
4467 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4469 * Changed the get_auth_methdod client operation to be asynchronous.
4470 It can be async if the application resolves the authentication
4471 method from the server during the negotiation. Added new
4472 SilcGetAuthMeth completion callback that the application will
4473 call after resolving the authentication method.
4475 Added function silc_client_request_authentication_method that
4476 the application can use to resolve the authentication method
4477 from the server. Added also SilcConnectionAuthRequest callback
4478 that the library will call after the server has replied. The
4479 application can call this function if it does not know the
4480 current authentication method.
4482 Affected files are lib/silcclient/client.c and
4483 lib/silcclient/silcapi.h.
4485 * The Irssi SILC client now automatically resolves the authentication
4486 method incase any configuration information is not present (and
4487 currently there never is). The affected file is
4488 irssi/src/silc/core/client_ops.c.
4490 * Fixed public key authentication from the client library.
4491 Affected file lib/silcclient/protocol.c. Changed also the
4492 protocol specification about the public key authentication in
4493 the connection authentication protocol. The actual data to be
4494 signed is now computed with a hash function before signing.
4496 * Fixed the public key authentication from the server as well.
4497 Affected file silcd/protocol.c.
4499 * Removed the mlock()'s from the memory allocation routines.
4500 Affected file lib/silcutil/silcmemory.c. The ./configure does
4501 not check anymore for the mlock(). Affected file is
4504 * Fixed USERS command in server to allow the execution of the
4505 command for private and secret channels if the client sending
4506 the command is on the channel. Affected file silcd/command.c.
4508 * Fixed silc_client_get_clients_local to return the clients
4509 count correctly. It could return wrong value. Affected file
4510 lib/silcclient/idlist.c.
4512 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4514 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4515 types. The assembler optimizations seemed not to like 64-bit
4516 data types. The assmebler optimizations thus are now enabled
4517 also for BSD systems as opposed to only enable them for Linux.
4519 * Do not check for threads at all on BSD systems. Affected
4520 file configure.in.pre.
4522 * Removed -n and -h options from the Irssi SILC Client since
4523 they are not used in silc.
4525 * Fixed the prime generation to assure that the first digit
4526 of the generated random number is not zero since our conversion
4527 routines does not like number strings that starts with zero
4528 digit. If zero digit is seen the random number is regenerated.
4529 This caused some corrupted RSA keys when the zero first digit
4530 was met. Affected file lib/silcmath/silcprimegen.c.
4532 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4534 * Fixed WIN32 configuration in the ./configure script.
4535 Fixed to include xti.h on environments that has it.
4536 Patches by Carsten Ilchmann and andrew.
4538 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4540 * Changed the silc_id_create_client_id to be collision
4541 resistant. It is now assured that there cannot be created
4542 two same client ID's. I suspect that some weird bugs in
4543 the server were actually caused by duplicate Client IDs.
4544 Affected file silcd/serverid.[ch]. A router receiving
4545 new ID now also assures and informs the sending server
4546 if the ID caused collision.
4548 * Changed the silc_id_create_channel_id to also assure that
4549 there are no collisions.
4551 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4553 * Statement about ignoring the Mutual Authentication flag when
4554 performing rekey with PFS was a bit misleading. It is ignored
4555 if it was set in the initial negotiation, it cannot be even
4556 set in the rekey. Fixed in the ke-auth draft. Started the
4557 new versions of the protocol drafts in the doc/.
4559 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4561 * Fixed a bug in silc_client_command_identify_save when saving
4562 new channel information. The channel name was no duplicated
4563 and caused crash on exit. Affected file is
4564 lib/silcclient/command_reply.c.
4566 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4568 * Fixed the getkey command handling in the server. Send just
4569 empty OK reply to the sender if the key could not be fetched
4570 (but everything else was ok, like the key just was not available).
4571 Changed the public key parameter to optional in the protocol
4572 specs so that empty OK reply can be sent. Affected file
4575 Added a message to Irssi SILC client to tell to user if the
4576 server did not return a public key.
4578 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4580 * Fixed a channel key regeneration bug. It registered new
4581 timeout tasks exponentially until all system resources were
4582 used. Affected file silcd/server.c.
4584 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4586 * Added the SILC Document generator to the scripts/silcdoc.
4587 It can be used to generate the Toolkit Reference Manual out
4588 of the source tree. Internally it will also use the RoboDoc
4589 generator now imported in util/robodoc.
4591 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4593 * Added couple of return's in rekey protocol if error orccurred
4594 during the protocol. The execution must be terminated.
4595 Affected file silcd/protocol.c. Also, terminate the protocol
4596 always with timeout.
4598 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4600 * The client's Client ID was created initally from the wrong
4601 nickname (it could have been in format nick@host) in the
4602 silc_server_new_client. Affected file silcd/packet_receive.c
4604 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4606 * Added some SILC_LOG_ERROR's to various error conditions
4607 if client could not be added to ID cache. Affected files
4608 silcd/packet_receive.c and silcd/server.c.
4610 * When client's sock->user_data is freed, NULL also the
4611 client->router and client->connection pointers. Added check
4612 for these pointers being NULL to various places around the
4613 code. Affected file silcd/server.c.
4615 * Added client->data.registered == TRUE checks to various
4616 places around the code to assure that unregistered client's
4617 are not handled when it is not allowed. Affected file
4620 * Added `bool registered' fields to all
4621 silc_idlist_[server|client]_get_* routines to indicate whether
4622 the fetched client needs to be registered or not. Affected
4623 file silcd/idlist.[ch].
4625 * Add your own entry as registered to the ID cache in the
4626 server. Affected file server.c.
4628 * Fixed a bug in silc_server_new_server. The SilcServer was
4629 set as the new server's context instead of SilcServerEntry.
4630 This naturally caused some weird bugs.
4632 * Added "updated" field the SilcChannelEntry which indicates
4633 the time since the channel entry was last accessed. This
4634 can be used to determine whether it is necessary to
4635 announce the channel after backup resuming protocol.
4636 Affected files silcd/idlist.[ch].
4638 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4640 * Do not delete the channel rekey task when adding it
4641 for in silc_server_create_channel_key.
4643 * Changed the silc_server_create_channel_key to return
4644 TRUE or FALSE to indicate the success of the channel key
4647 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4649 * Fixed MSVC++ project files and added missing files to
4650 Makefiles under win32/.
4652 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4654 * Do not add TCP_NODELAY flag if the operating system
4655 does not have it defined. Affected files are
4656 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4658 * Fixed buffer overflow from Irssi SILC Client. Affected
4659 file irssi/src/fe-common/core/themes.c.
4661 * Fixed double free in client library in the file
4662 lib/silcclient/client.c when disconnecting from server.
4664 * Applied double free patch from cras to Irssi SILC client.
4665 Affected files irssi/src/core/[modules/expandos].c
4667 * Fixed the disconnection handling to Irssi SILC Client.
4668 The application must call silc_client_close_connection
4669 in ops->connect client operation in case of failure of
4670 the connection. Affected file is
4671 irssi/src/silc/core/client_ops.c.
4673 * Do not set sock->protocol to NULL in the function
4674 silc_client_close_connection after executing the protocol's
4675 final callback since the sock might not be valid anymore.
4676 Affected file lib/silcclient/client.c.
4678 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4680 * Do not enable SILC_THREADS if the linking with libpthread
4681 did not happen. Affected file configure.in.pre.
4683 * Added notion to protocol specification that server must
4684 verify the sent authentication payload with CMODE when
4685 setting the channel founder key. Implemented it to the
4686 server. Affected file silcd/command.c.
4688 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4690 * Added _EXTRA_DIST SILC distribution variable to the
4691 distributions file. It is used to conditionally add extra
4692 files or directories to the specific distribution. Affected
4693 files ./prepare, Makefile.am.pre and distributions.
4695 Removed the `_' from the start of the distribution names.
4698 * Added README.WIN32 for instructions to compile the Toolkit
4701 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4703 * Fixed a double free in disconnection in the server. Affected
4704 file is silcd/server.c.
4706 * Fixed the lib/silcske/groups.c to work now also with GMP
4707 MP library. The string conversion did not work when using
4708 specific base and the base is indicated in the string as well.
4710 * Created win32/ directory which now includes MSVC++ specific
4711 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4712 It will appear only in the toolkit distribution
4714 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4716 * Changed the key material distribution function in case when
4717 the hash output is too short. The data is now concatenated
4718 a bit differently than it used to. Made the change to the
4719 SKE protocol specification.
4721 * Added better GMP detection to configure.in.pre. A patch
4724 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4726 * Fixed a minor bug in SKE that might cause some problem on
4727 some platforms. Affected file lib/silcske/silcske.c.
4729 * Added the cookie checking for initiator in the SKE. It checks
4730 that the responder returns the sent cookie unmodified. The
4731 affected file is lib/silcske/silcske.c. Added new SKE
4732 error type INVALID_COOKIE that can be sent during the
4733 negotiation. Fixed some memory leaks as well.
4735 * Added the "invalid cookie" error message to Irssi SILC client's
4738 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4740 * Added `task_max' field to the SilcClientParams to indicate
4741 the maximum tasks the scheduler can handle. If set to zero,
4742 default values are used. Affected file lib/silcclient/silcapi.h.
4744 * Fixed memory leaks in silc_client_close_connection. Affected
4745 file lib/silcclient/client.c.
4747 * Added silc_client_del_client_entry to client library to free
4748 all memory of given client entry. Affected file is
4749 lib/silcclient/idlist.[ch].
4751 * Added new functions silc_client_del_channel and
4752 silc_client_del_server to delete channel and server entries.
4753 Affected file lib/silcclient/[silcapi.h/idlist.c].
4755 * Removed silc_client_del_client_by_id from silcapi.h.
4757 * Fixed the INFO command to return the server's own info
4758 correctly when querying by Server ID. Affected file is
4761 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4763 * Removed the non-blocking settings in WIN32 code in the
4764 silc_sock_[read/write] and added SleepEx instead. Affected
4765 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4766 of input data is now checked with FIONREAD and ioctlsocket.
4768 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4770 * Call silc_schedule_task_del_by_context in the
4771 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4772 Affected file lib/silccore/silcprotocol.c.
4774 * Call silc_protocol_cancel for active protocols in the
4775 silc_server_close_connection if the funtion
4776 silc_server_free_sock_user_data has not been called.
4777 Affected file silcd/server.c.
4779 * Generic tasks cannot be deleted using the del_by_fd
4780 task deleting function since generic tasks does not match
4781 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4783 * Added a notion to SILCOPER help file that the SILCOPER works
4784 only on router server, not on normal server.
4786 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4788 * Added for WIN32 support for the new scheduler as well.
4789 Affected file lib/silcutil/win32/silcwin32schedule.c.
4791 * Fixed the SHA1 implementation to work on various platforms.
4793 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4795 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4796 API. It is part of the scheduler now. Everything else is
4797 as previously but some functions has changed their names.
4798 Checkout the lib/silcutil/silcschedule.h for the interface.
4799 Updated all applications to use the new interface. Affected
4800 files are lib/silcutil/silcschedule.[ch].
4802 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4804 * Found a bug in the SKE implementation. The HASH value,
4805 specified by the protocol, was not computed correctly. The
4806 public key of the responder was not added to the computation
4807 even though it is mandatory. Affected file lib/silcske/silcske.c.
4808 This unfortunately causes incompatibilities with older
4809 clients and servers.
4811 * Added WIN32 specific network init and uninit functions:
4812 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4813 the Winsock2. Affected file lib/silcutil/silcnet.h and
4814 lib/silcutil/win32/silcwin32net.c.
4816 * Set the socket always to nonblocking mode on WIN32 after
4817 reading data or writing data. Affected file is
4818 lib/silcutil/win32/silcwin32sockconn.c.
4820 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4822 * Fixed various compilation problems under WIN32. Affected
4823 files lib/silcutil/win32/silcwin32thread.c and
4824 lib/silcutil/win32/silcwin32schedule.c.
4826 * Removed all _internal.h #includes from public header
4827 files. Internal headers must never be included from
4830 Removed also the lib/silcske/payload_internal.h file.
4832 * All include files that may be needed (public and some others
4833 included by the public headers) by application developers are
4834 now copied to the ./includes directory. It does not copy any
4835 internal headers. Affected file Makefile.defines.pre and all
4836 Makefile.am's under lib/ and subdirs.
4838 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4840 * Do not change the ~/.silc directory's permissions automatically.
4841 Affected file irssi/src/silc/core/clientutil.c.
4843 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4845 * Do not cancel the protocol in silc_server_close_connection
4846 it might cause recursion. Now cancelled in the function
4847 silc_server_free_sock_user_data. Affected file silcd/server.c.
4849 * Fixed the silc_server_remove_clients_by_server to regenerate
4850 the channel keys correctly finally. Added also new function
4851 silc_server_remove_clients_channels to actually do it.
4852 Affected file silcd/server.c.
4854 * Fixed the silc_server_new_channel to not crash by giving
4855 wrong router to the new channel. Affected file is
4856 silcd/packet_receive.c.
4858 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4860 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4861 which is given as argument to the silc_client_alloc now.
4862 It can be used to configure the client and set various parameters
4863 that affect the function of the client.
4865 * The USERS command in server did not check whether the channel
4866 is private or secret. Affected file silcd/command.c.
4868 * Added new argument to the USERS command in protocol specification.
4869 The USERS command now can take the channel name as argument
4870 as well. Added support for this in client and server and
4871 updated the protocol specs.
4873 * Completed the GETKEY command in client. It can be now used
4874 to fetch also servers public key not only some clients.
4875 Affected files lib/silcclient/command[_reply].c.
4877 * Added silc_client_get_server to return server entry by the
4878 server name. Affected files lib/silcclient/silcapi.h and
4881 * Redefined the IDENTIFY command in protocol specification to be
4882 more generic. It now can be used to query information about
4883 any entity in the SILC Network, including clients, servers and
4884 channels. The query may be based either the entity's name
4885 or the ID. Added support for this in both client and server.
4887 Affected files silcd/command.c and lib/silcclient/command.c
4888 and command_reply.c.
4890 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4891 the _from_client and _from_server functions. Affected file
4894 * Added silc_client_get_channel_by_id_resolve to the file
4895 lib/silcclient/silcapi.h to resolve channel information by
4896 its ID. Added also silc_client_get_channel_by_id that
4897 does not resolve it from the server.
4899 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4901 * Added SilcServerEntry context into the client library
4902 to represent one server. The INFO command now allocates
4903 these to save the resolved server info. For now on the
4904 client library will also keep information about servers,
4905 connected and resolved with INFO.
4907 The INFO command now allocates the SilcServerEntry context
4908 and saves the server info there. The COMMAND_REPLY in
4909 the INFO now returns the parameters to application in
4910 same order as defined in the protocol specification.
4912 The entries are cached in the client->server_cache.
4914 * The INFO command is now issued after received the Client ID
4915 from the server. Affected file lib/silcclient/client.c.
4917 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4918 to the application as the mode changer might be server.
4919 It is guaranteed that NULL is not returned anymore to the
4920 application. Affected file lib/silcclient/client_notify.c.
4922 The ID Type is now also passed to the application so that
4923 it can check whether the returned entry is SilcClientEntry
4926 Added new function silc_client_get_server_by_id to return
4927 the server entry by ID. Affected files are the
4928 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4930 * Do not create the channel in the Irssi SILC Client when issuing
4931 the JOIN command but when received the sucessful JOIN command
4932 reply. Otherwise the channel might get created even though we
4933 could not join it. The Affected file is
4934 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4936 * Fixed a channel joining bug in router. The router must also
4937 check the channel modes, invite and ban lists etc. when serving
4938 the JOIN command sent by normal server. Affected file is
4939 silcd/command.c. The router now resolves the client's
4940 information from the server who sent the JOIN command if it
4941 does not know it, and processes the JOIN command only after
4944 * Changed the SilcCommandCb to take new argument; void *context2.
4945 Affected file lib/silccore/silccommand.h
4947 The second argument in the command callbacks in the server now
4948 includes the SilcServerCommandReplyContext if the command was
4949 called as pending command callback from the command reply.
4950 Otherwise it is NULL. When called as pending the status of the
4951 command reply will be checked and if it was erronous the
4952 error will be sent to the original sender of the command.
4953 This way the client always receives the error messages even
4954 though the server was actually the one who received the error
4955 when it resent the command to router, for example. Affected
4956 files silcd/command[_reply].[ch].
4958 * Fixed sending WHOWAS command's error message to client if
4959 the requested client could not be found. It was missing.
4962 * Changed the CMODE and CUMODE commands reply arguments in the
4963 protocol specification. The Channel ID is now sent in both
4964 of the commands to identify the channel. Implemented this
4965 new feature to the client and server. Affected files
4966 lib/silcclient/command_reply.c and silcd/command.c.
4968 * Made better checks for invite and ban lists in the JOIN
4969 command in server. Affected file silcd/command.c.
4971 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4973 * The server now performs the incoming host IP/DNS lookup
4974 using the silc_socket_host_lookup and thus does not block
4975 the server anymore. Affected file silcd/server.c.
4977 * Completed the multi-thread support for SILC Scheduler in
4978 the lib/silcutil/silcschedule.c.
4980 * Fixed the configure.in.pre to detect the pthread correctly
4983 * Fixed a deadlock in silc_task_queue_wakeup in the file
4984 lib/silcutil/silctask.c.
4986 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4988 * Added new function silc_schedule_wakeup that is used in
4989 multi-threaded environment to wakeup the main thread's
4990 schduler. It needs to be used when a thread adds a new task
4991 or removes a task from task queues. After waking up, the
4992 scheduler will detect the task queue changes. If threads
4993 support is not compiled in this function has no effect.
4994 Implemented the wakeup mechanism to both Unix and WIN32
4995 systems. Affected files are lib/silcutil/silcschedule.[ch],
4996 lib/silcutil/unix/silcunixschedule.c and the
4997 lib/silcutil/win32/silcwin32schedule.c.
4999 * Added new function silc_task_queue_wakeup to wakeup the
5000 scheduler by the specified task queue. Affected file
5001 lib/silcutil/silctask.[ch].
5003 * The silc_socket_host_lookup_start now wakes up the scheduler
5004 after adding the timeout task. Affected file is
5005 lib/silcutil/silcsockconn.c.
5007 * The silc_socket_host_lookup is synchronous now if the threads
5008 support is not compiled in. However, the callback is still
5009 called asyncronously through the scheduler, anyway. Affected
5010 file lib/silcutil/silcsockconn.c.
5012 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5014 * Added new function silc_socket_host_lookup to perform
5015 asynchronous IP and FQDN lookups for the socket connection.
5016 Affected files lib/silcutil/silcsockconn.[ch].
5018 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5020 * Added SILC_MUTEX_DEFINE to define the mutex on environments
5021 that may or may not compile the mutex support in.
5023 Changed the silc_mutex_alloc interface. It allocates the
5024 mutex now to the sent pointer and returns TRUE or FALSE.
5026 Affected file lib/silcutil/silcmutex.h.
5028 * Wrote the SILC Task Queue interface to support multi-threads.
5029 Affected file lib/silcutil/silctask.[ch].
5031 * Wrote the SILC Scheduler to support multi-threads. Affected
5032 file lib/silcutil/silcschedule.c.
5034 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5036 * Implemented the SILC Mutex API and SILC Thread API for WIN32
5037 in lib/silcutil/win32/.
5039 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5041 * Defined SILC Mutex API and SILC Thread API and implemented
5042 them for Unix. Affected files are
5043 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
5044 lib/silcutil/unix/silcunixmutex.c and
5045 lib/silcutil/unix/silcunixthread.c.
5047 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5049 * Fixed the silc_server_remove_clients_by_server's channel
5050 key re-generation. The hash table handling was incorrect
5051 and would not work with many channels. Affected file is
5054 * Fixed some memory leaks around the server code.
5056 * Rewrote the silc_server_get_users_on_channel to support IPv6
5057 based Client ID's. Affected file silcd/server.c.
5059 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
5060 specification. However, a separate document must be written
5061 to define the detailed signing procedure and the payload
5062 associated with the flag. Defined the flag to the
5063 lib/silccore/silcchannel.h as well.
5065 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5067 * Changed the dynamic tables to static size tables in the
5068 lib/silccrypt/silchmac.c.
5070 * Removed GCC dependencies from the code. A patch by cras.
5072 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5074 * Do not show the error "Error receiving packet bla bla"
5075 in server if it really was not an error (-2 means that reading
5076 is pending). Affected file silcd/server.c.
5078 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5080 * Fixed a possible crash in silc_server_remove_clients_by_server
5081 in silcd/server.c. Fixed there also some memory leaks.
5083 * Fixed the silc_idlist_replace_client_id. It could replace
5084 wrong key in the hash table. Affected file silcd/idlist.c.
5086 * Do not check whether there are global users on the channel
5087 if the channel->global_users is FALSE. Affected functions
5088 silc_server_remove_from_one_channel and
5089 silc_server_remove_from_channels in silcd/server.c. Also,
5090 do not check if the removed client is local as we can be
5091 sure that global client was not removed from the channel
5092 and checking for global users is not needed.
5094 * The silc_server_remove_clients_by_server now re-generates
5095 the channel keys correctly for those channels that had
5096 clients removed from them. Affected file silcd/server.c.
5098 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5100 * Found the reason of random crashes in the server. We weren't
5101 ignoring the SIGPIPE signal (which can be sent in write())
5102 and it crashed the server. Affected file silcd/silcd.c.
5104 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5106 * Assure that sock->user_data is not NULL in the function
5107 silc_server_packet_send in silcd/packet_send.c.
5109 * Disconnect the remote connection if it could not be added
5110 to any ID lists in the server. The affected file is
5113 * Check in silc_server_packet_send[_real/dest] that the
5114 socket is not disconnecting and ignore the data if it is.
5115 Affected file silcd/packet_send.c.
5117 * Define inline to __inline on native WIN32 compilation.
5118 Affected file includes/silcwin32.h.
5120 * Added some explicit type casts for inline code since MSVC
5121 require them. Affected files lib/silcutil/silcbuffer.h,
5122 lib/trq/silcdlist.h and lib/trq/silclist.h.
5124 * Print warning in log files from now on if the packet
5125 decryption fails. Affected file silcd/server.c.
5127 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5129 * Changed the `say' client operation's interface to accept
5130 new `type' argument to indicate the type of the message sent
5131 by the library. The application may filter the library's
5132 messages according the type. The affected file is the
5133 lib/silcclient/silcapi.h.
5135 * Added two new functions to lib/silcclient/silcapi.h:
5136 silc_client_del_client and silc_client_del_client_by_id.
5137 Affected file lib/silcclient/idlist.c.
5139 * Moved the clientincludes.h from includes/ to silc/ and
5140 serverincludes.h from includes/ to silcd/.
5142 * The modes for the CMODE and CUMODE are now passed as
5143 uint32 for application with COMMAND_REPLY. The affected
5144 file is lib/silcclient/command_reply.c.
5146 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5148 * /WHOIS without arguments shows client's own information.
5149 Affected file lib/silcclient/command.c.
5151 * Changed PING to not accept any arguments. The specs
5152 says that client can ping only the connected server so
5153 requiring an argument is not needed. Affected file is
5154 lib/silcclient/command.c.
5156 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5158 * Fixed a fatal bug in private message sending and reception
5159 encryption and decryption when using private message keys.
5160 The implementation was incorrect and did not follow the
5161 specification. It causd that some of the message were
5162 lost since it did not use the sending and receiving keys
5163 as the protocol suggests. This has been fixed and will cause
5164 incompatibilities with older clients when sending private
5165 message encrypted with private message keys. Affected files
5166 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
5167 and various other in Irssi SILC Client.
5169 Added `responder' boolean argument to the functions
5170 silc_client_add_private_message_key[_ske] to indicate when
5171 the key is added as responder or initiator of the key
5174 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5176 * Removed the silc_ske_check_version function and created
5177 a SilcSKECheckVersion callback. Added also a function
5178 silc_ske_set_callbacks that is now used to set all SKE
5179 callbacks. The callback functions are not given to
5180 the SKE functions anymore, but this function is used to
5183 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
5185 * Added `silc_version' argument to the silc_client_alloc
5186 to define the version of the application for the library.
5187 The library will use the version string to compare it
5188 against the remote host's (usually a server) version
5189 string. Affected file lib/silcclient/silcapi.h
5191 * Added the KE protocol context to Key Agreement context
5192 in client library so that we can abort the SKE if it
5193 is in process when we get timeout. Affected file is
5194 lib/silcclient/client_keyagr.c.
5196 * Do not resolve the client ID forever if it returns in the
5197 first time that such client does not exist. This was done
5198 for example with private message. Affected file is
5199 lib/silcclient/client_prvmsg.c.
5201 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5203 * Do not add regex.h for WIN32. The affected file
5204 includes/silcincludes.h.
5206 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
5207 not work yet 100%. It generates the DLL's automatically
5208 when compiling with --with-win32 under cygwin.
5210 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5212 * lib/contrib/regex.c is not compiled on WIN32.
5214 * Added silc_net_get_socket_opt function to the
5215 lib/silcutil/silcnet.h.
5217 * Added includes/silcwin32.h for WIN32 specific includes
5220 * Do not use ptime structure or any of the posix process
5221 functions on WIN32 in lib/silccrypt/silrng.c.
5223 * Added silc_gettimeofday to provide generic function
5224 for struct timeval on all platforms. Added the function
5225 to lib/silcutil/silcutil.h.
5227 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5229 * Moved the lib/silccore/silcsockconn.[ch] to the utility
5230 library as they clearly belong there. As a plus side we
5231 can make the actual socket connection routines platform
5234 Added also new generic function silc_socket_read and
5235 silc_socket_write (that used to be silc_packet_[read/write].
5236 The implementation of these are platform specific.
5238 * Added WIN32 specific routines of silc_socket_[read/write]
5239 to lib/silcutil/win32/silcwin32sockconn.c.
5241 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5243 * Added preliminary support for native WIN32 compilation under
5244 cygwin (using the -mno-cygwin option for GCC) to the
5245 ./configure.in.pre. The --with-win32 now prepares the
5246 compilation for native WIN32.
5248 * Rewrote the SILC Scheduler interface in the file
5249 lib/silcutil/silcschedule.h. The scheduler is now context
5250 based and does not have anymore any global static scheduler.
5251 Moved the Unix scheduler to the lib/silcutil/unix/ directory
5252 and created lib/silcutil/win32 directory for WIN32 based
5255 * Added Unix specific network routines to the
5256 lib/silcutil/unix/silcunixnet.c and the old
5257 lib/silcutil/silcnet.c includes now only generic routines.
5259 Added WIN32 specific network routines to the
5260 lib/silcutil/win32/silcwin32net.c.
5262 * Added Unix specific utility functions from the
5263 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
5265 * Added WIN32 SILC Scheduler to the file
5266 lib/silcutil/win32/silcwin32schedule.c. The code is of course
5269 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5271 * Do not handle JOIN notify in the server if the target client
5272 is not registered (idata->registered == FALSE). The affected
5273 file is silcd/packet_receive.c.
5275 * Update the nickrec->founder in event_cumode in the Irssi SILC
5276 client. Affected file irssi/src/silc/core/silc-channels.c.
5278 * Fixed the CUMODE_CHANGE notify handling in the server when
5279 server and router are announcing their clients on channels.
5280 Now the mode changes are saved and notified correctly. The
5281 affected file is /silcd/packet_receive.c.
5283 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
5284 They really did not replace the cache entry in the ID Cache.
5285 Now they do that. Affected file silcd/idlist.c.
5287 * Fixed the KICK notify handling in the Irssi SILC client to
5288 update the channel records so that the kicked client does not
5289 appear to be on the channel. The affected file is
5290 irssi/src/silc/core/silc-channels.c.
5292 * Always update the conn->current_channel when executing command
5293 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
5295 * Fixed the KILL notify handling in Irssi SILC client to remove
5296 the killed client on all channels.
5298 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5300 * Fixed the silc_parse_command_line to remove extra spaces
5301 from the start and end of the arguments. Affected file is
5302 lib/silcutil/silcutil.c.
5304 * Cancel and free any active protocol in the function
5305 silc_server_close_connection. Affected file silcd/server.c.
5307 * Cancel and free any active protocol in the function
5308 silc_client_close_connction. Affected file is
5309 lib/silcclient/client.c.
5311 * Do not execute the KILL command for clients that are in
5312 history (ie. they are not in the network). Affected file is
5315 * Fixed KILL notify handling, client does not crash anymore.
5316 Affected file irssi/src/silc/core/silc-channels.c.
5318 * Reduced the default packet buffer size from 2048 to 1024 in
5319 lib/silccore/silcpacket.c.
5321 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5322 counter to the SKE context that is incresed when the SKE library
5323 performs async operation outside the library. If the outside
5324 process frees the SKE context and FREED status will be set
5325 and the library will detect after the sync operation that the
5326 libary is freed. The affected files are
5327 lib/silcske/silcske[_status].[ch].
5329 * Resolve the client entry information in the function
5330 silc_client_channel_message to assure that NULL pointer is not
5331 passed as client entry to the application. */
5333 * Fixed the task timeout calculation to assure that there is
5334 never negative timeouts. The affected file is
5335 lib/silcutil/silcschedule.c.
5337 * Fixed the channel user mode notification sending in server.
5338 It was sent point-to-point to the router (or to server by router)
5339 but it needs to be destined to a channel. The routines now
5340 supports sending the channel user mode notifys to the channels
5341 when announcing clients and channels. Affected files are
5342 silcd/server.c and silcd/packet_receive.c.
5344 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5345 It did not actually replace the old channel entry in the cache.
5346 Affected file lib/silcclient/client_notify.c.
5348 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5350 * Fixed a possible crash in silc_packet_send_prepare. It now
5351 assures always that there is enough space in the buffer and
5352 at the tail area of the buffer (for MAC).
5354 Fixed the inbound buffer reallocation in silc_packet_read.
5355 It was old code and did not handle the reallocation correctly.
5358 The affected file is lib/silccore/silcpacket.c.
5360 * Fixed buffer overflow in silc_parse_nickname in the file
5361 lib/silcutil/silcutil.c.
5363 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5365 * make install generates new server keys only if there is not
5368 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5370 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5371 Added check that if the NOREPLY is set then we will not send
5372 the away message. This avoids infinite loop of away messages
5373 if both clients are away. The affected file is
5374 lib/silcclient/client_prvmsg.c.
5376 * Fixed client crash if /NICK was given without arguments.
5377 Affected file lib/silcclient/command.c.
5379 * Server does not send the invite list in INVITE command back
5380 to the client if the list was not altered. Added this notion
5381 to the protocol spec as well. Affected file silcd/command.c.
5383 Fixed possible crash in INVITE command by checking the
5384 value of silc_server_get_client_route command.
5386 * Fixed the INVITE notify type handling. The arguments are now
5387 taken in correct order and client does not crash. The affected
5388 file is irssi/src/silc/core/silc-channels.c.
5390 Removed the "Inviting xxx to channel" message from the
5391 client library away and let the application handle it.
5392 Affected file lib/silcclient/command.c. Added that message
5393 to Irssi SILC client's message formats.
5395 * Fixed CMODE command crash in client. It now checks the
5396 amount of arguments correctly and does not crash. The affected
5397 file is lib/silcclient/command.c.
5399 * Do not create new channel automatically in silc_channels_join
5400 but check whether the channel by that name already exists.
5401 Affected file irssi/silc/core/silc-channels.c.
5403 * Do not send the SERVER_SIGNOFF to router if the disconnected
5404 entity was the router. Affected file silcd/server.c.
5406 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5407 SILC client as it was missing from there.
5409 Added the handling of the KICK notify to the Irssi SILC client
5410 as it was missing. Added "you have been kicked" message to
5411 Irssi SILC client's message modules formats.
5413 Added the handing of the KILL notify to the Irssi SILC client
5414 as it was missing. Added the kill message module formats
5417 The affected file is irssi/src/silc/core/silc-channels.c.
5419 * The router did not save the channel mode the server announced.
5420 Affected file silcd/packet_receive.c.
5422 * Fixed a possible crash in INFO command in server. If the
5423 server did not provide the server info it crashed. Affected
5424 file silcd/command.c.
5426 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5428 * Fixed the GETKEY command in the server to check also the
5429 global list. Otherwise the GETKEY would not work correctly
5430 in normal SILC server. Affected file silcd/command.c.
5432 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5434 * Fixed GETKEY crash, it crashed if the command did not succseed.
5436 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5438 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5439 is now real and not just an macro interface to GMP.
5441 Removed the entire GMP from the source tree and imported new
5442 NSS MPI library instead. Reason for removing GMP is that it is
5443 extremely large and compiles extremely slow. The NSS MPI
5444 is only a few files and compiles in less than 10 seconds.
5445 The speed is also about the same as GMP. The MPI is imported
5446 to lib/silcmath/mpi.
5448 If the system has GMP installed we will still use the GMP.
5449 If it is not then the NSS MPI will be compiled.
5451 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5453 * Merged a long nickname (127 characters long) crash bugfix from
5454 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5456 * Merged a freed memory reference bugfix from Irssi CVS tree.
5457 Affected file irssi/src/core/commands.c.
5459 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5461 * Added the server's public key sving and verification to the
5462 server when performing the SKE. This was missing and the
5463 remote server's (or router's) public key was accepted without
5464 checking whether we have it previously or trust it at all.
5465 Affected file silcd/protocol.c.
5467 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5469 * Check in the silc_server_timeout_remote if protocol is active
5470 and make sure that the protocol's final callback is called so
5471 that all memory if freed. Affected file silcd/server.c.
5473 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5475 * silc_server_whois_send_reply crashed the server if the nickname
5476 was 127 characters long. Affected file silcd/command.c.
5478 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5480 * Added sanity check to the silc_server_new_client. If the hostname
5481 is provided inside username then check that the provided hostname
5482 really is the same as the resolved one. If the hostname was not
5483 resolved then check it from the public key. Affected file is
5484 silcd/packet_receive.c.
5486 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5487 if the server disconnected us and the connection is not valid
5488 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5490 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5491 the library to the lib/silcutil/silcutil.[ch].
5493 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5495 * Close log file after open. Affected file
5496 lib/silcutil/silclog.c.
5498 * Check whether sock == NULL in silc_client_send_packet and return
5499 if it is. Affected file lib/silcclient/silcclient.c.
5501 * Check rec->entry == NULL in the Irssi SILC Client before
5502 sending the channel message. Affecte file is
5503 irssi/src/silc/core/silc-servers.c.
5505 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5507 * Merged a splitted window bugfix from Irssi CVS tree. The
5508 affected file is irssi/src/fe-text/textbuffer-view.c.
5510 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5511 It did not print nickname.
5513 * Improved the distributions system a bit.
5515 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5517 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5518 irssi/src/fe-text/gui-window.c.
5520 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5521 to in-active server. The affected file is
5522 irssi/src/silc/core/client_ops.c.
5524 * Resolve the client in USERS command reply if the entry does
5525 not have username resolved. The affected file is
5526 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5527 command to WHOIS command to really resolve stuff. The USERS
5528 is not used any more in any critical section so WHOIS can
5529 be used even though it might be slower than IDENTIFY.
5531 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5534 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5536 * Changed the protocol API a bit more consistent in the
5537 lib/silccore/silcprotocol.[ch].
5539 * Changed the following headers to ROBODoc format:
5541 lib/silccore/silcpayload.h
5542 lib/silccore/silcprotocol.h
5543 lib/silccore/silcsockconn.h
5545 All core library headers are now formatted.
5547 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5549 * Fixed a bug in Irssi SILC client; do not show that you are
5550 server/router operator if you really are not. Affected file is
5551 irssi/src/silc/core/client_ops.c.
5553 * Renamed silc_command_free_payload to silc_command_payload_free.
5554 Affected file lib/silccore/silccommand.h
5556 * Added silcmath.h to include the prototoypes of various routines
5557 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5560 * Changed the following headers to ROBODoc format:
5562 lib/silccore/silcchannel.h
5563 lib/silccore/silccommand.h
5564 lib/silccore/silcid.h
5565 lib/silccore/silcidcache.h
5566 lib/silccore/silcmode.h
5567 lib/silccore/silcnotify.h
5568 lib/silccore/silcpacket.h
5569 lib/silcmath/silcmath.h
5571 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5573 * Added checking to the server code not to start the server if
5574 ciphers and stuff are not configured properly. Affected files
5575 silcd/serverconfig.[h] and silcd/server.c.
5577 * Changed the layout of the header files of the public interfaces
5578 in the SILC libraries. The new layout supports ROBODoc
5579 documentation tool (and some others) so that it is easy to create
5580 a library reference manual. All the other headers and source
5581 code must still follow the CodingStyle document. Also source
5582 code must not include these ROBODoc stuffs, only the headers.
5583 Furthermore, all public interface headers must now be named
5584 by using `silc' prefix, example: silcapi.h, silccipher.h.
5585 Some files were renamed due to this. All the other headers
5586 must not be used as public interfaces. I will update the
5587 CodingStyle document later. Changed following headers, so far:
5589 lib/silcclient/silcapi.h
5590 lib/silccore/silcauth.h
5591 lib/silccore/silcprivate.h
5592 lib/silccrypt/silcdh.h
5594 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * Removed silc_client_packet_send_flush from the client library
5599 as it is not needed. Affected file lib/silcclient/client.[ch].
5601 * Added printing of message of unresolved authentication method
5602 to the Irssi SILC client. Added it to the module formats.
5603 Removed the same message from the client library.
5605 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5607 * Added new distribution feature, DISTLABEL. Every distribution
5608 can define own preprocessor label that can be used in the
5609 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5610 file distributions, acconfig.h.pre and prepare.
5612 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5614 * Added Makefile.defines_int to include the actual definitions
5615 for Makefile.defines.in. Tested the new distribution system,
5616 created distributions and tested installation.
5618 * Added AWAY message printing to the Irssi SILC client. Added
5619 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5621 * Added SCONNECT command to call the SILC's CONNECT command.
5622 Cannot use CONNECT directly since Irssi uses that internally.
5623 Affected file irssi/src/silc/core/silc-servers.c.
5625 Added ACTION local command. It is same as ME command but takes
5626 the channel as mandatory argument.
5628 Rewrote some of the Irssi's help files to suite for SILC
5631 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5633 * Added Makefile.defines[.in] that should for now on be included
5634 in all Makefile.am file in the source tree. That file includes
5635 all common compilation definitions for SILC source tree.
5637 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5639 * Minor changes to the ./prepare script to change the package
5640 name according the distribution name to the configure.in.
5642 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5644 * Created new distribution system. Added file `distributions'
5645 that defines all the distributions that can be created out of
5646 the SILC source tree. The ./prepare script now reads that
5647 file to determine how to prepare the distributions. The
5648 first argument to the ./prepare is the name of the distribution
5649 and second is the version of the distribution. If given
5650 without arguments it creates the default (toolkit) distribution
5651 with the default version (defined in ./prepare).
5653 All Makefile.am files that are subject to the distributions
5654 are now named as Makefile.am.pre. These are ./Makefile.am
5655 and lib/Makefile.am. Others may be changed later.
5657 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5659 * Added invite list, ban list, some key management and connection
5660 error message printing to module formats in the Irssi SILC client.
5662 * Added new silc_client_set_away_message to set the away message
5663 that is back to the person who sent private message. The
5664 affected file lib/silcclient/silcapi.h and the
5665 lib/silcclient/client_prvmsg.c.
5667 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5669 * Fixed the private message sending in the Irssi SILC client,
5670 added local command KEY to the Irssi SILC client.
5672 Added key management and key agreement message formats to the
5673 irssi/src/fe-common/silc/module-formats.[ch].
5675 Added USERS (alias WHO) printing, server/router operator
5676 indication and LIST command printing to the module formats.
5678 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5680 * Fixed channel joining notify handling, cumode notify handling
5681 from Irssi SILC client.
5683 * Added SILC specific module-formats to the Irssi SILC client so
5684 that SILC specific message hilighting, colors etc is possible.
5685 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5687 Added channel mode, channel user mode, actions, notices,
5688 whois and whowas printing to the the module-formats.c.
5690 * Fixed a bug in channel deletion in the server. The channel
5691 is not left to the cache even if the channel founder auth mode
5692 is set when there are no users anymore on the channel. Affected
5693 file silcd/server.c.
5695 * The silc_net_localhost now resolves the entire hostname including
5696 the domain name. Affected file lib/silcutil/silcnet.c.
5698 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5700 * Changed the ask_passphrase client operation to be ascynchronous.
5701 It has now a completion callback and a context that the
5702 application must call after it has got the passphrase from
5703 the user. Affected files lib/silcclient/silcapi.h,
5704 lib/silcclient/protocol.c, lib/silcclient/command.c and
5707 Added SilcAskPassphrase callback that the application calls
5708 to deliver the passphrase to the library.
5710 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5711 The public key verification and especially a certificate
5712 verification is asynchronous procedure.
5714 Added new SILC_SKE_STATUS_PENDING status to indicate the
5715 request is pending and a callback will be called to finalize
5718 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5719 indicate that remote end did not send its public key (or
5720 certificate), even though we require it. Added check for this
5721 condition in the SKE. This was a security bug, now fixed.
5723 Defined new SilcSKEVerifyCbCompletion callback that is called
5724 when the verification process is completed.
5726 The affected files lib/silcske/silcske_status.h and
5727 lib/silcske/silcske.[ch].
5729 * Changed the verify_public_key client operation to be async
5730 as well. Defined SilcVerifyPublicKey callback that is used to
5731 indicate the success of the public key verification process.
5733 Changed the server and client to use the new async client
5736 * Changed the Irssi SILC client's internal scheduler to be called
5737 twice as many times as it used to be. As a result the client
5738 should be a bit faster now. Affected file is
5739 irssi/src/silc/core/silc-core.c.
5741 * Added support to Irssi SILC client of asynchronous public key
5742 verification and passphrase inquiry. Affected file is
5743 irssi/src/silc/core/silc-core.c.
5745 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5747 * Do not say "You have left channel %s" in client library.
5748 Moved it to the application. Affected files are
5749 lib/silcclient/command.c and silc/client_ops.c.
5751 * Fixed silc_client_get_clients. Command context was not
5752 duplicated and was freed memory in the callback. Affected
5753 file lib/silcclient/idlist.c.
5755 * Do not say "you are now talking..." on JOIN command in the
5756 client library. The appliation must handle it.
5758 * Do not say ".. changed topic to" in command reply in the
5759 client libary. The application must handle it.
5761 * Fixed TOPIC command sending in the client library.
5763 * Fixed a memory leak in silc_client_command_free in the file
5764 lib/silcclient/command.c.
5766 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5768 * Imported a modified version of Irssi client to the source tree.
5769 The Irssi will be used to create a new client called
5770 Irssi SILC. Imported to irssi/.
5772 Added silc_core_init_finish function to the Irssi. Affected
5773 file irssi/configure.in.
5775 A lot changes in the Makefile.ams around the irssi tree.
5777 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5779 * Do not rehash if the new size is same as the old size of the
5780 hash table, in the silc_hash_table_rehash*. The affected file
5781 lib/silcutil/silchashtable.c.
5783 * Replaced hash_table_del_by_context calls from the server
5784 (when channel->user_list and client->channels) to the
5785 hash_table_del as it is sufficient and faster.
5787 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5789 * Added silc_hash_table_list, silc_hash_table_get and the
5790 SilcHashTableList structure to provide an alternative way to
5791 traverse the hash table. The affected files are
5792 lib/silcutil/silchashtable.[ch].
5794 * Changed the server's idlist routines to use the hash table
5795 routines to optimize the code.
5797 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5799 * Replaced the client entry's `channel' list and channel entry's
5800 `user_list' list to hash tables for optimized lookup. Changed
5801 the code to use the hash table interface around the code.
5802 Affected file lib/silcd/idlist.[ch].
5804 * Added `auto_rehash' boolean argument to the function
5805 silc_hash_table_alloc to indicate whether the hash table should
5806 auto-rehash when it thinks is appropriate time. It will
5807 increase the hash table size if the there is twice as much
5808 entries in the table than the size of the table, and will
5809 decrease the size if there are twice as less entries than
5810 the size of the table.
5812 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5814 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5816 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5818 * silc_idcache_purge_by_context deletes the entry now by context
5819 as it is supposed to do. Affected file lib/silccore/idcache.c.
5821 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5822 client is not anymore valid (WHOWAS givens the info) and not
5823 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5825 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5827 * Removed the `data' and `data_len' arguments from the ID Cache
5828 interfaces and added `name' argument. ID Cache does not handle
5829 anymore the binary data only a names associated with given ID.
5831 * When hashing a Client ID with silc_hash_id the entire ID is
5832 not hashed anymore, instead only the hash of the Client ID is
5833 hashed. This way we can access the Client ID from the cache
5834 with Client ID but with the hash of the ID (which is a hash of
5835 the nickname) as well without any difference in performance.
5837 Added also silc_idcache_find_by_id_one_ext to do one on one
5838 searching when we have the actual ID. Added also function
5839 silc_hash_client_id_compare. The affected files are
5840 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5842 * When hashing the name associated with a ID it is always done
5843 in lowercase. This way we can access the cache without worrying
5844 about case-sensitivity, even though, for example nicknames are
5847 * Fixed a bug in server with channel message sending. It put
5848 wrong ID type as destination ID. The affected file
5849 silcd/packet_send.c.
5851 * silc_idcache_del_by_context now deletes from all hash tables
5852 by context. Affected file lib/silccore/idcache.c.
5854 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5856 * Changed the client library to use the new ID Cache interface.
5857 Changes around the source tree.
5859 * Added silc_hash_table_rehash_ext to rehash with specific
5860 hash function. Affected file lib/silcutil/silchashtable.[ch].
5862 * Added silc_hash_string_compare to compare two strings in the
5863 hash table. Affected file lib/silcutil/silcutil.[ch].
5865 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5867 * Added new function silc_idcache_del_by_context into the
5868 lib/silccore/idcache.[ch].
5870 * Changed the server's ID list routines to use the new ID Cache
5871 interface. Changes around the source tree.
5873 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5875 * Added silc_hash_table_del[_by_context]_ext functions in to the
5876 lib/silcutil/silchashtable.[ch].
5878 Removed silc_hash_table_find_all* routines and added new
5879 silc_hash_table_find_foreach to replace them.
5881 Added silc_hash_table_replace_ext function as extended
5882 replacing function. Separated the simple hash table interface
5883 from the extended hash table interface in the file
5884 lib/silcutil/silchashtable.h.
5886 * Fixed minor bugs and changed it to use some of the new
5887 hash table functions in lib/silccore/idcache.c
5889 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5891 * Added new function silc_hash_table_find_all to return all keys
5892 in the hash table by the specified key. As the hash table is
5893 collision resistant it also makes it possible to have several
5894 duplicate keys in the hash table. This function may be used to
5895 find all of the keys from the hash.
5897 Added user_context arguments to the SilcHashFunction,
5898 SilcHashCompare and SilcHashDestructor to deliver user specified
5901 Added new fuctions silc_hash_table_find[_all]_ext to do
5902 extended lookup with specified hash and compare functions and
5903 specified user contexts.
5905 Added new function silc_hash_table_add_ext to add the key
5906 with specified hash function and user context.
5908 Added new function silc_hash_table_foreach to traverse all
5909 entrys in the hash table. Added SilcHashForeach callback
5912 Added new function silc_hash_table_del_by_context to delete
5913 the entry only if the context associated with the key matches.
5915 Affected files are lib/silcutil/silchashtable.[ch].
5917 * Removed silc_hash_[server/client/channel]_id and added just
5918 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5919 silc_hash_id_compare to compare two ID's using as the hash table
5920 comparison function. Added also silc_hash_data to hash
5921 binary data and silc_hash_data_compare to compare it.
5923 * Removed silc_idlist_find_client_by_hash as it is not needed
5924 anymore. Affected file silcd/idlist.[ch].
5926 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5927 to use internally the SilcHashTable. The new ID Cache is a lot
5928 faster than the old one. Some of the ID Cache interface was also
5929 rewritten and obsolete and stupid functions were removed.
5931 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5933 * Added entry_count field to the SilcHashTable to keep the number
5934 of the entries in the table. Implemented the function
5935 silc_hash_table_rehash. Added new function
5936 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5938 Fixed a minor bug in silc_hash_table_free.
5940 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5941 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5942 into the lib/silcutil/silcutil.[ch].
5944 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5946 * Implemented a collision resistant hash table into the
5947 lib/silcutil/silchashtable[ch]. See the header and the source
5948 for the SilcHashTable API.
5950 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5952 * Merged dotconf version 1.0.2 into lib/dotconf.
5954 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5956 * Do not compile anything in lib/silcsim/* if the SIM support
5957 is not enabled. The tree should now compile without problems
5960 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5962 * Compiled the SILC under cygwin. Compiled and tested briefly
5963 without problems. More tests needed. The SIMs didn't compile
5966 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5968 * Fixed possible crash in silc_get_username in the
5969 lib/silcutil/silcutil.c.
5971 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * Fixed a va_arg in silc/client_ops.c.
5975 * Oops, RC5 routines were named AES and caused some problems
5976 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5978 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5980 * Added new SilcIDIP structure into the lib/silccore/id.h and
5981 replaced the old `ip' fields from all SILC ID's to that type.
5982 This is a step towards IPv6 support.
5984 The silc_id_get_len takes now the ID as an extra argument.
5985 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5986 both IPv4 and IPv6 based ID's.
5988 The affected files are lib/silccore/id.[ch] and other files
5989 around the tree using these routines.
5991 * Removed the ID length arguments in server from various
5992 silc_server_send_notify_* routines -> they are not needed
5995 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5997 * Fixed memory leak in silc_encode_pem_file in the file
5998 lib/silcutil/silcutil.c.
6000 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6002 * Check minor version as well in the SKE. Affected files are
6003 silcd/protocol.c and lib/silcclient/protocol.c.
6005 * Added --identifier option to the server so that an identifier
6006 can be when creating the public key for the server. Affected
6007 file is silcd/silcd.c.
6009 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
6010 lib/silccrypt/silcpkcs.c.
6012 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6014 * Register default ciphers and stuff when using -C option with
6015 the server. Affected file sildc/silcd.c.
6017 * Put back the servers public key filename format, it is better
6018 than the new one. For now, the client keys are saved with the
6019 new filename format. The affected file silc/client_ops.c.
6021 * Implemented the Cipher API for the rest of the ciphers that
6022 did not implement it or implemented it the wrong way.
6024 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6026 * Register default ciphers and stuff when using the -S option
6027 in the client. Affected file silc/silc.c. Same also when
6028 creating new key pair with -C option.
6030 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6032 * Fixed the silc_verify_public_key client operation function to
6033 save the public keys differently. The fingerprint is now
6034 used as filename and not the hostname. This way also the
6035 client keys are saved uniquely and not with hostnames. The
6036 affected file is silc/client_ops.c.
6038 * Trimmed the silc_hash_fingerprint function to remove extra
6039 whitespaces from the end of the fingerprint. The affected
6040 file is lib/silccrypt/silchash.c.
6044 * Added silc_cipher_register_default function to register all
6045 default ciphers. It can be used when configuration files
6046 does not exist and the application does not want any specific
6047 ciphers in any specific order.
6049 The SilcDList is now used as silc_cipher_list dynamically
6050 allocated cipher list. Removed the static list all together
6051 and now all ciphers must be allocated to the dynamic list.
6052 The silc_cipher_alloc routine was changed to check only the
6055 All silc_cipher_* routines that used to return int returns
6058 The affected files lib/silccrypt/silccrypt.[ch].
6060 * The same thing was done to silc_hash_* as for silc_cipher_*
6061 routines. Affected files lib/silccrypt/silchash.[ch].
6063 * The same thing was done to silc_pkcs_* as for silc_cipher_*
6064 routines. Affected files lib/silccrypt/silcpkcs.[ch].
6065 Added also silc_pkcs_[un]register[_default] functions.
6066 Removed the data_context from the PKCS API.
6068 * Added silc_hmac_register_default function to register default
6069 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
6070 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
6071 to unregister all hmacs at once.
6073 * Register the default ciphers, hash functions, PKCSs and HMACs
6074 if client's configuration file does not exist. The affected
6077 * The client did not load the hash functions from the SIM
6078 modules at all. Added support for this. Affected file is
6079 silc/clientconfig.c.
6081 * When decoding public key with silc_pkcs_public_key_decode, check
6082 the supported algorithm only if PKCS are registered. Affected
6083 file lib/silccrypt/silcpkcs.c. The same was done with the
6084 silc_pkcs_private_key_decode.
6086 * Fixed the SILC List routines to keep the list always in order.
6087 It used to change the list's order when traversing the list but
6088 not it preserves the order. Affected file lib/trq/silclist.h.
6090 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6092 * Added the client library to use the SilcSocketConnection's
6093 reference counter (by silc_socket_dup) to prevent the bug that
6094 the socket object may be freed underneath async operation.
6096 * The name resolv library checking fixes in the configure.in.pre.
6099 * Created new version of the protocol drafts for future
6100 development. The -03 drafts are the ones that will be changed
6101 in the trunk now and the -02 will remain as they are.
6103 * Send list of CUMODE notifys to the router when announcing
6104 the channel users to the router. Affected file silcd/server.c.
6105 If the router receiving channel founder CUMODE for a channel
6106 that already has channel founder it will send CUMODE notify
6107 to the sender to remove the channel founder rights from the
6108 announced client. Affected file silcd/packet_receive.c.
6110 * The CUMODE notify may now use Server ID as well as the entity
6111 who changes the mode. Updated protocool specs.
6113 * Updated INSTALL and README files.
6115 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6117 * New web pages in the http://silc.pspt.fi. The pages was
6122 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6124 * Implemented the [DenyConnectin] config section in the server.
6125 Added silc_server_config_denied_conn to check whether incoming
6126 connection is denied. Affected file silcd/serverconfig.[ch].
6128 * Do not check the ports when checking the incoming configuration
6129 data if the port is 0, meaning any. Affected file is
6130 silcd/serverconfig.c.
6132 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6134 * Fixed buffer overflow in silc_string_compare in the file
6135 lib/silcutil/silcutil.c.
6137 * Fixed double free in silc_server_command_leave in the file
6140 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6142 * Fixed the version checking in the server. Affected file is
6145 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6147 * Fixed the configuration data fetching when accepting new
6148 connections in the server. Affected file silcd/server.c.
6150 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6152 * Added `sender_entry' argument to the function
6153 silc_server_packet_relay_to_channel so that we can check
6154 whether some destination actually belongs to the same route
6155 the sender belongs (ie, we must not resend the packet to the
6156 sender). Affected file silcd/packet_send.[ch].
6158 * Added `servername' field to the SilcClientEntry in the server
6159 to hold the name of the server where client is from. Affected
6160 file is silcd/idlist.h.
6162 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6164 * Moved the channel message encrypting in the router betwen
6165 router connections from silc_server_channel_message to the
6166 silc_server_packet_relay_to_channel since we want to check
6167 whether we have anybody channel before encrypting anything.
6168 Affected files silcd/packet_[receive/send].c.
6170 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6172 * Fixed the [AdminConnection] server config section to support
6173 multiple entries. Affected file silcd/serverconfig.c.
6175 * Added support into the server to check the validity of the
6176 incoming connection before executing any KE or authentication
6179 * The connection configuration is now saved to the KE and
6180 connection auth protocol contexts and not fetched anymore in
6181 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
6183 * The local hosts listenning address and port is also resolved
6184 now when starting the server. We want to have the socket object
6185 to include the real address and port for the listener. Added
6186 new function silc_net_check_local_by_sock into the files
6187 lib/silcutil/silcnet.[ch].
6189 * Fixed a broadcast bug in server -> do not broadcast if we
6192 * Fixed a routing bug. Do not route broadcast packets ever.
6193 Broadcast packets must be processed always and not routed since
6194 they may be destined to some other host than yourself and thus
6195 would get routed without no good reason. Affected file is
6198 * Added function silc_server_config_is_primary_route to check
6199 whether primary router connection has been configured (a router
6200 configuration that we are initiating). If there is not, we
6201 will assume that there is only two routers in the SILC network
6202 and we will use the incoming router connection as our primary
6203 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
6205 * Changed the order of the broadcasting. Broadcast _after_ the
6206 packet has been processed not before. Affected file is
6209 * Fixed a [ClientConnection] parsing bug. The port was never
6210 parsed correctly thus resulting to port 0. Affected file
6211 silcd/serverconfig.c.
6213 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
6214 argument and did not set the broadcast packet flag. Affected
6215 file silcd/packet_send.c. Fixed same bug in the function
6216 silc_server_send_notify as well.
6218 * If we receive NEW_ID packet for our own ID in the server, ignore
6221 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6225 * Removed the nickname from the Private Message Payload.
6226 Updated the code and the protocol specs.
6228 * Updated protocol specs for submitting to the IETF.
6230 * Tweaked the Random Number Generator a bit. Affected file
6231 lib/silccrypt/silcrng.c. Exported a new function
6232 silc_rng_[global]_add_noise which can be used to add more
6235 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6237 * Do not parse packets with different timeout when protocol
6238 is active -> may cause problem with rekey. Affected file
6241 * When server receives signoff notify it must not create
6242 new channel key if the client is on any channels since the
6243 sender of the signoff notify will create it.
6245 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6247 * Added printing of error messages during SKE protocol from the
6248 failure packet sent by server during SKE. Affected file
6251 * Removed the client's failure_callback handling with timeout
6252 and handle it immediately when received.
6254 * The SKE library returned wrong type in SUCCESS and FAILURE
6255 packets. They must be 32 bit MSB not 16 bit MSB.
6257 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6259 * Ok, rewrote the logic of the re-key and now it seems to work.
6260 I tested it on high traffic with frequent re-keys without
6261 problems. Added hmac_receive (and renamed hmac to hmac_send)
6262 in SilcClientConnection in lib/silcclient/client.h and
6263 in SilcIDListData in silcd/idlist.h. Also, removed the
6264 SilcPacketParserContext's cipher and hmac fields as they are
6265 not needed anymore and actually caused some problems when
6266 the ciphers and hmac's changed underneath the packet parser.
6268 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6270 * If re-key protocol is active then process the incoming packets
6271 synchronously since we must assure that icoming packets encrypted
6272 with the old key is processed before the new keys is set to
6273 use. This is true other packets than for REKEY packets.
6274 Affected file silcd/server.c. The same was done to client library
6275 as well, affected file lib/silcclient/client.c.
6277 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6279 * Fixed bug in client and server to accept the force send if
6280 the packet is send from silc_[server/client]_packet_process
6281 function. Otherwise the packets are never delivered, oops.
6283 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6285 * Disable force sending of packets when REKEY protocol is active.
6286 We must assure that no packet is sent directly when rekey is
6287 performed. All packets must be sent through packet queue.
6288 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
6289 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
6290 function is silc_[server/client]_packet_send_real to check
6293 * Replaced the SIM paths from example config files to
6294 /usr/local/modules. Also, make install creates now
6295 /usr/local/silc/logs directory to hold all the SILC server
6298 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

6309 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6311 * When MAC computation fails the silc_packet_decrypt returned 0
6312 even though it was supposed to return -1. Fixed this. The
6313 affected file is lib/silccore/silcpacket.c.
6315 * Do not replace the config files in /etc/silc (in make install)
6316 if they already exist. Affected file ./Makefile.am.
6318 * Do not send re-key packets immediately but through packet queue.
6319 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6321 * Changed silc_net_check_host_by_sock to return FALSE if the
6322 IP/DNS could not be resolved. Though, it returns the IP address
6323 now even if it could not resolve it (but returns also FALSE).
6324 Affected file lib/silcutil/silcnet.[ch].
6326 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6328 * Added silc_pkcs_decode_identifier to decode the public key's
6329 identifier. Affected file lib/silccrypt/silpkcs.[ch].
6330 Added also silc_pkcs_free_identifier. Added also new context
6331 SilcPublicKeyIdentifier.
6333 * Added -S option to the silc client. It is used to dump the
6334 contents of the specified public key file.
6336 * Changed the PKCS api to return the public key length when
6337 setting the public key.
6339 * Fixed a fatal bug in the public and private key file loading.
6340 Affected file lib/silccrypt/silcpkcs.c.
6342 * Execute the packet parsing for client with zero (0) timeout
6343 if the protocol is active. Affected file silcd/server.c.
6345 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6347 * Made the key generation options to the silcd program. Added
6348 -C option, equivalent to client's option.
6350 * Added new [ServerKeys] config section to the server. It
6351 configures the server's public and private key.
6353 * Defined generic Public Key Payload into the protocol
6354 specification to send specific type of public keys and
6357 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6358 public key or certificate.
6360 * Implemented the GETKEY command to the server and to the
6361 client library and on user interface.
6363 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6365 * Made preliminary `make install' work.
6367 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6369 * Added SilcServerRekey context into silcd/idlist.h.
6371 * Added the PFS support as defined in the specification to the
6372 SKE protocol. Affected files lib/silcske/*.c.
6374 * Added `ske_group' field to the SilcServerRekey context to hold
6375 the number of the SKE group that is used with PFS in re-key.
6376 Affected file silcd/idlist.h.
6378 * Added PFS re-key support to the server. Affected file is
6381 * Added silc_protocol_cancel to cancel execution of the next
6382 state of the protocol. Affected file is
6383 lib/silccore/silcprotocol.[ch].
6385 * Added the re-key support with and without PFS to the client
6386 library. Re-key is performed once in an hour, by default.
6388 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6389 Added silc_client_rekey_callback and silc_client_rekey_final.
6390 Affected files are lib/silcclient/protocol.[ch] and
6391 lib/silcclient/client.[ch].
6393 * Removed the `hmac_key' and `hmac_key_len' fields from the
6394 SilcClientConnection structure; not needed. Affected file is
6395 lib/silcclient/client.h.
6399 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6401 * Do not ask whether user wants to use the negotiated private key
6402 for private messages, just use it. Affected file is
6403 silc/local_command.c.
6405 * Added `send_enc_key' and `enc_key_len' fields to the
6406 SilcIDListData structure since they are needed in the re-key
6407 phase. Affected file is silcd/idlist.[ch].
6409 * Implemented the simple re-key protocol into the server.
6410 Affected files silcd/server.c and silcd/protocol.[ch]. The
6411 re-key will be performed once in an hour, by default.
6413 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6414 Added silc_server_rekey, silc_server_rekey_callback and
6415 silc_server_rekey_final.
6417 * Removed Tunneled flag from the protocol. Updated the code
6418 and the specifications.
6420 * Adde `pfs' field to the SilcIDListData to indicate whether
6421 the PFS is to be performed in the re-key. Affected file is
6424 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6426 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6427 int64 of at least the xintXX size. If void * is less that 4
6428 bytes uint32 * will be used. Defined bool as boolean.
6430 * Changed _ALL_ unsigned long and unsigned int to uint32,
6431 unsgined short to uint16 in the source tree.
6433 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6434 not handle clients that has entry->data.registered == FALSE.
6435 They are not in the network anymore. Affected file is
6438 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6440 * Implemented the sending of the SERVER_SIGNOFF notify in the
6441 server. Affected file is silcd/server.c.
6443 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6444 Added also silc_notify_payload_encode_args into the
6445 lib/silccore/silcnotify.[ch].
6447 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6448 Affected file silcd/packet_receive.c.
6450 * Implemented the SERVER_SIGNOFF notify handling in the client
6451 library. Affected file lib/silcclient/client_notify.c. Also,
6452 implemnted the printing of the SERVER_SIGNOFF info to the
6453 application. Affected file silc/client_ops.c.
6455 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6456 if the deleting was successful. Affected file silcd/idlist.[ch].
6458 * Added support for public key authentication in the connection
6459 authentication protocol in the client library. Affected file
6460 lib/silcclient/protocol.c.
6462 * Changed the server's silc_idlist_get_clients_by_* interface
6463 to support already allocated array so that new entries may be
6464 added to pre-allocated array. Affected file silcd/idlist.[ch].
6465 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6466 and command replies.
6468 * All command reply functions in the server now calls the
6469 pending command callback even if error occured. This way the
6470 error will be delivered to the client as well. Affected files
6471 silcd/command.c and silcd/command_reply.c.
6473 * Fixed INFO command to return local server's info if no server
6474 was provided. Affected file lib/silcclient/command.c.
6476 * Removed RESTART command for good. Updated the code and the
6479 * Rewrote parts of the task system. It is a bit simpler now.
6480 Removed unsued task priorities. The affected files are
6481 lib/silcutil/silctask.[ch].
6483 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6485 * Moved the USERS printing from the library to the application.
6486 Affected files lib/silcclient/command.c and silc/client_ops.c.
6488 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6492 * Added channel key re-key support. The re-key is perfomed
6493 only by the router and is done once in an hour. Added `rekey'
6494 field to the SilcChannelEntry in the server. Affected files
6495 silcd/server.c and silcd/idlist.h.
6497 * Added silc_task_unregister_by_context into the file
6498 lib/silcutil/silctask.[ch].
6500 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6502 * Added SILC_UMODE_GONE mode to indicate when the client is not
6503 present in the SILC network. Added also support to the local
6504 command AWAY that will set this mode. Added support of showing
6505 "xxx is gone" in WHOIS command. The USERS command shows the
6506 gone status as well.
6508 * Fixed setting server and router operator privileges in the
6509 server's UMODE command. Affected file silcd/command.c.
6511 * Merged the SKE KE1 and KE2 payloads into one payload. The
6512 new KE payload is equivalent to the old KE2 payload.
6514 Cleaned up the SKE Start Payload parsing. It now uses the
6515 simple buffer unformatting to do the parsing. A lot faster
6518 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6519 to the SKE that is used to indicate whether both of the SKE
6520 parties should perform authentication. By default only the
6521 responder performs authentication. By setting this flag also
6522 the initiator must do authentication. By default it is unset
6523 since in normal SKE case, client to server connection, only
6524 the responder should do authentication. When doing SKE between
6525 two clients both should perform authentication. Updated the
6526 code and the protocol specs.
6528 * A little fix to IDENTIFY command in the server. Search the
6529 client first by hash not nickname. Affected file is
6532 * Fixed the silc_client_close_connection to support closing
6533 the client to client connections wihtout deleting too much
6534 data. Affected file lib/silcclient/client.c.
6536 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6537 are received if protocol used to be active but is not anymore
6538 the application would crash due to NULL pointer dereference.
6539 Affected files silcd/server.c and lib/silcclient/client.c.
6541 * Added `hash' field to the SilcClientConnection to include
6542 the hash function negotiated in the SKE protocol.
6544 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6545 to set the channel founder authentication data. A client can
6546 claim the founder rights later by providing the authentication
6547 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6548 This way the channel founder can regain the channel founder
6549 privileges even it is left the channel. This works only on
6550 local server and the client must be connected to the same
6551 server to be able to regain the founder rights. Updated the
6552 protocol specs accordingly.
6554 Added support to the CMODE command in the client to set the
6555 founder auth data. Read the README to see how to set it.
6557 Added support to the CUMODE command to claim the founder
6558 rights. Read the README to see how to do it.
6560 Added support for the founder authentication to the Channel
6561 Entry in the server. Affected file silcd/idlist.h.
6563 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6564 server's CMODE command. Affected file silcd/command.c.
6566 * Added the following new functions into lib/silccore/silcauth.[ch]:
6567 silc_auth_get_method and silc_auth_get_data.
6569 * The server now saves the remote hosts public key to the
6570 SilcIDListData pointer. Affected file silcd/protocol.c.
6572 * The normal server now does not remove the channel entry from
6573 the cache if the founder authentication data is set. It used
6574 to remove it if the founder was the last one on the channel on
6575 the server and left the channel. The auth data is saved and
6576 if the channel is re-joined later the old entry is used with
6577 the old auth data. Affected files silcd/command_reply.c and
6580 * Removed the `pkcs' field from the SilcIDListData structure
6581 in the server; it is not used. Affected file silcd/idlist.h.
6583 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6585 * Fixed packet processing on slow links. Partial packets were
6586 never re-processed because the incoming data buffer was cleared
6587 by the application. Application must not directly clear the
6588 sock->inbuf, the packet processing routines handle it. Fixed
6589 this in client library and in server.
6591 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6593 * Fixed the WHOIS and IDENTIFY send reply function to really
6594 check whether to send list or just one entry. Affected file
6597 * Cleaned up the LEAVE command's channel key distribution. The
6598 affected file silcd/command.c.
6600 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6601 can enforce the channel mode as well. In that case the ID
6602 includes the ID of the server. The code now enforces the
6603 mode change if the router have different mode than the server.
6605 * The notify client operation with CMODE_CHANGE notify can now
6606 return NULL client_entry pointer if the CMODE was not changed
6607 by client. Application must check for this.
6609 * Added <Server ID> argument to INFO command to support server
6610 info fetching by Server ID.
6612 * Added silc_server_announce_get_channel_users to get assembled
6613 packets of channel users of the specified channel. Affected
6614 file silcd/server.[ch].
6616 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6617 was freed underneath the ID Cache.
6619 * Re-announce clients when the server received CHANNEL_CHANGE
6620 notify from the router. Affected file silcd/packet_send.c.
6622 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6624 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6625 crashed since it did not handle the fact that there is no cipher
6626 called "3" and didn't check the error condition. Now fixed.
6628 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6629 flag. It can be used to send message requests.
6631 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6633 * Implemented the RESTART command in the client.
6635 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6636 notice type messages. Added notice printing to the user
6639 * The channel keys are not re-generated if the channel's mode
6640 is PRIVKEY, ie private key on the channel exists. Affected
6641 files silcd/server.c and silcd/command.c.
6643 * Fixed a little bug in channel message delivery when channel
6644 private keys are set in the server. Affected file is
6645 silcd/packet_send.c.
6647 * Changed the setting on channel->on_channel = TRUE from the
6648 silc_client_save_channel_key to the JOIN command reply. The
6649 key payload is not received if the private channel key is set.
6650 Affected file lib/silcclient/command_reply.c and the
6651 lib/silcclient/client_channel.c.
6653 * When the CMODE_CHANGE notify is sent and the channel private
6654 key mode is removed the channel key must be re-generated in
6655 other cells as well. Added this support for the router in the
6656 silcd/packet_receive.c.
6658 * Added new local command NOTICE to send notice message on
6659 channel. Affected file silc/local_command.[ch].
6661 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6663 * Added new local command ME to the client. It is used to send
6664 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6665 some action. Affected file silc/local_command.[ch].
6667 * Changed channel_message and private_message client operations
6668 to deliver the message flags to the application. Added also
6669 the `flags' arguments to the silc_client_send_channel_message
6670 and silc_client_send_private_message functions. Affected file
6673 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6675 * Redefined the Private Message Payload to support private message
6676 keys and to support the new private message flags. Updated
6677 the protocol specs. Flags makes it possible to have for example
6678 CTCP style messages.
6680 * Added new type SilcPrivateMessagePayload and defined an API
6681 for it in the lib/silcclient/silcprivate.[ch].
6683 * Tested private message private keys successfully. Tested the
6684 private message key set, unset and list commands with the new
6687 * Redefined the Channel Message Payload to include the channel
6688 message flags (equal with private message flags) to support
6689 for example CTCP style messages.
6691 * Defined some of the message (for channel and private message)
6692 flags. Updated the protocol specs and added the flags to the
6693 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6695 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6697 * Added SilcKeyAgreementStatus type to the key agreement routines
6698 to indicate the current status and error if one occured.
6699 The status types are defined in the lib/silcclient/silcapi.h.
6701 * Added new local command KEY that is used to set and unset private
6702 keys for channels, set and unset private keys for private messages
6703 with remote clients and to send key agreement requests and
6704 negotiate the key agreement protocol with remote client. The
6705 key agreement is supported only to negotiate private message keys,
6706 it currently cannot be used to negotiate private keys for channels,
6707 as it is not convenient for that purpose.
6709 * Fixed a minor pending callback setting bug in the function
6710 silc_client_get_client_by_id_resolve, now the function works.
6711 Affected file lib/silcclient/idlist.c.
6713 * Added function silc_net_get_local_port to get local bound
6714 port by socket. Added to lib/silcutil/silcnet.[ch].
6716 * Added `sockets' and `sockets_count' fields to the SilcClient
6717 object. They hold the sockets of the listenning sockets in
6718 the client. Listenning sockets may be for example the key
6719 agreement server. Affected file lib/silcclient/client.[ch].
6720 Added functions the silc_client_add_socket and the
6721 silc_client_del_socket. They are exported to the application
6724 * Added ~./silc/clientkeys to support other client's public keys.
6726 * Renamed verify_server_key client operation to verify_public_key
6727 and added one argument to indicate the type of the connection
6728 (server, client etc.).
6730 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6732 * Added silc_server_connection_auth_request to handle the
6733 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6734 silcd/packet_receive.[ch].
6736 * Added silc_server_send_connection_auth_request into the
6737 silcd/packet_send.c to send the connection auth request packet.
6739 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6742 * Fixed the public key authentication in responder side in the
6743 server. The `auth_data' pointer includes the SilcPublicKey
6744 not the path to the public key. Affected file silcd/protocol.c.
6746 * Implemented the public key authentication in the initiator side
6747 in the server. Affected file silcd/protocol.c.
6749 * Removed the [RedirectClient] config section from the server
6750 configuration. Is not needed and I don't want to implement it.
6752 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6754 * Cleaned up the CMODE command in the server. It now works
6755 correctly and supports all the modes defined in the protocol.
6756 Affected file is silcd/command.c.
6758 * Added `hmac_name' field to the SilcChannelEntry in the server
6759 to hold the default HMAC of the channel. It can be set when
6760 creating the channel (with JOIN command). Affected files
6763 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6764 type to indicate the change of the current cipher and hmac
6765 on the channel. Client can safely ignore the <cipher> argument
6766 (if it chooses to do so) since the CHANNEL_KEY packet will
6767 force the channel key change anyway. The <hmac> argument is
6768 important since the client is responsible of setting the new
6769 HMAC and the hmac key into use.
6771 * Fixed the CMODE command in the client library as well.
6773 * Tested CMODE command in router environment successfully.
6775 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6777 * Show the version of the remote client (or server) when connecting
6778 to the server. It is logged to the log file. Affected file
6779 is silcd/protocol.c.
6781 * Fixed the KILLED notify handling in the client library. The
6782 client must be removed from all channels when receiving the
6785 Also, do not remove the client entry when giving the KILL
6786 command but when the KILLED notify is received.
6788 * Removed silc_idlist_find_client_by_nickname from the server.
6789 Not needed anymore. Affected files silcd/idlist.[ch].
6791 * Implemented the CHANNEL_CHANGE notify type handling to the
6792 server. Affected file silcd/server.c.
6796 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6798 * Added silc_server_send_notify_invite to send the INVITE
6799 notify between routers.
6801 * Implemented the INVITE command correctly to the server.
6803 * Implemented the INVITE notify type handling in the server.
6805 * Implemented the INVITE command to the client library and on the
6808 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6810 * Added function silc_server_get_client_resolve to find the
6811 client entry by ID from all ID lists and then resolve it
6812 (using WHOIS) if it cannot be found. Affected file is
6815 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6817 * Implemented the BAN command to the client library.
6819 * The JOIN command in the server now checks the invite list
6822 * Changed the silc_command_reply_payload_encode_va and the
6823 silc_command_payload_encode_va to support that if argument is
6824 NULL it ignores and checks the next argument. Affected file
6825 lib/silccore/silccommand.c.
6827 * Added silc_server_send_notify_ban to send the BAN notify
6828 type between routers.
6830 * Chaned the silc_notify_payload_encode to support that if
6831 argument is NULL it ignores and checks the next argument.
6832 Affected file lib/silccore/silcnotify.c.
6834 * Tested ban lists in router environment successfully.
6836 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6838 * Implemented BAN command to the server, in silcd/command.[ch].
6840 * Removed the BAN and INVITE_LIST modes from the CMODE command
6843 * Added function silc_string_match to regex match two strings.
6844 Affected files lib/silcutil/silcutil.[ch].
6846 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6848 * Redefined parts of the SilcChannelEntry in the server to support
6849 the new ban and invite lists.
6851 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6853 * Redefined the INVITE command. The same command can be used to
6854 invite individuals to the channel but also to manage the invite
6855 list of the channel (to add to and remove from the invite list).
6856 Updated the protocol specs.
6858 * Added new command SILC_COMMAND_BAN that can be used to manage
6859 the ban list of the channel. Updated the protocol specs.
6861 * Removed the channel modes: the SILC_CMODE_BAN and the
6862 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6863 in the CMODE command. The equivalent features are now available
6864 using INVITE and BAN commands. Updated the protocol specs.
6866 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6867 in the network about change in the current ban list. The notify
6868 type is not used by the client.
6870 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6871 support the invite lists.
6873 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6875 * Added new function silc_string_regexify that converts string
6876 including wildcard characters into regex string that can
6877 be used by the GNU regex library. Added into the file
6878 lib/silcutil/silcutil.[ch].
6880 Added silc_string_regex_combine to combine to regex strings
6881 into one so that they can be used as one regex string by
6882 the GNU regex library. Added into the file
6883 lib/silcutil/silcutil.[ch].
6885 Added silc_string_regex_match to match two strings. It returns
6886 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6888 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6890 * Imported GNU regex to the soruce tree into lib/contrib.
6891 Fixed some compiler warning from the regex.c.
6893 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6895 * Fixed MOTD command in the server to work in router environment.
6897 * Fixed the MOTD command in the client library to support
6898 the server argument in the command.
6900 * Added `nickname_len' argument to the silc_idlist_add_client
6901 in the server, as the `nickname' argument may be binary data
6904 * Added silc_idlist_get_channels to return all channels from
6907 * Implemented LIST command to the server. Affected file is
6910 * Implemented the LIST command to the client library and on the
6913 * Added [<user count>] argument to the LIST command reply.
6914 With private channels the user count is not shown.
6916 * Updated TODO and README.
6918 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6920 * The client entry's data.registered must be TRUE even with
6921 global client entry on global client list. The data.registered
6922 is used to check whether the client is anymore in the network,
6923 for example with WHOWAS command so it must be valid.
6925 * Fixed the WHOWAS command in the server. It now actually works
6926 in router environment. Added function into silcd/command_reply.c
6927 silc_server_command_reply_whowas_save.
6929 * Added silc_idlist_purge function to the silcd/idlist.c
6930 to periodically purge the ID Cache.
6932 * Fixed INFO command in the server. It works now in router
6933 environment. Added <server name> argument to the INFO command
6934 reply. Updated the protocol specs.
6936 * Fixed minor bug in silc_idcache_purge to not purge if the
6937 expire value is zero.
6939 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6940 they were buggy because of the WHOWAS information.
6942 * Fixed local command MSG to handle the async resolving of
6943 the remote client properly. It used to fail the first MSG.
6944 Affected file silc/local_command.c.
6946 * Added `data_len' field to SilcIDCache context.
6948 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6950 * Update TODO. Todo in commands in the server.
6952 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6954 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6955 used by routers as broadcast packet to inform other routers
6956 about the changed user mode.
6958 Implemented the notify handling in the server. Affected file is
6959 silcd/packet_receive.c. Added the function
6960 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6962 * Added new generic Channel Payload and deprecated the New Channel
6963 Payload. The New Channel Payload is now the generic Channel
6966 * Added new argument `mode' to the silc_server_send_new_channel
6967 as it is required in the Channel Payload now.
6969 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6970 and created a new and real SilChannelPayload to represent the
6971 new generic Channel Payload. Implemented the encode/decode
6972 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6974 * Added silc_server_get_client_channel_list to return the list
6975 of channels the client has joined for WHOIS command reply.
6976 Affected file silcd/server.[ch].
6978 * Implemented the channel list sending in the WHOIS command reply
6979 in server and in the client.
6981 Implemented the channel list displaying on the user interface
6982 as well. Affected file silc/client_ops.c.
6984 * Added silc_channel_payload_parse_list to parse list of Channel
6985 Payloads. It returns SilcDList list of SilcChannelPayloads.
6986 Client for example can use this function to parse the list of
6987 channels it receives in the WHOIS command reply. The caller
6988 must free the list by calling silc_channel_payload_list_free.
6989 Affected files lib/silccore/silcchannel.[ch].
6991 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6993 * Added one new argument <user mode> to the WHOIS command reply
6994 to return the mode of the user in SILC. Updated the protocol
6997 Implemented it to the server and client.
6999 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7001 * Fixed the mode printing on the user interface on joining.
7002 Affected file silc/client_ops.c.
7004 * Implemented the UMODE command and user modes in general to the
7005 client library and to the user interface.
7007 * Implemented the UMODE command to the server.
7009 * The server now sends UNKNOWN_COMMAND error status if client sends
7010 unknown command. Affected file silcd/command.c.
7012 * All server commands now handle the command identifier the right
7013 way when sending the command reply to the client. The client can
7014 use to identify the command replies with the identifier.
7016 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7018 * Added silc_server_get_client_route to resolve the route to
7019 the client indicated by the client ID. Affected file is
7022 * Added silc_server_relay_packet as general function to relay
7023 packet to arbitrary destination. This deprecates functions
7024 like _send_private_message_key, _relay_notify etc. Affected
7025 file is silcd/packet_send.[ch].
7027 Removed silc_server_send_key_agreement,
7028 silc_server_send_private_message_key and
7029 silc_server_packet_relay_notify functions from the file
7030 silcd/packet_send.[ch].
7034 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
7035 server. Affected file silcd/packet_receive.[ch].
7037 * Implemented the KILL command to the client. Implemented the
7038 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
7039 Affected files lib/silcclient/command[_reply].c and
7040 lib/silcclient/client_notify.c. Implemented the KILL notify
7041 printing in the user inteface.
7043 * Fixed a lot silc_parse_nick memory leaks from the client
7044 library in the file lib/silcclient/command.c.
7046 * Changed the silc_server_send_notify_on_channels's `sender'
7047 argument from SilcSocketConnection to SilcClientEntry to
7048 check the sender as entry and not as connection object and not
7049 to send to the client provided as argument. The affected file
7050 is silcd/packet_send.[ch].
7052 * The notify packets that are destined directly to the client used
7053 to not to be processed by the server. Now changed that and the
7054 server processes all notify packets. After relaying the packet
7055 to the client the notify packet is processed in the server.
7057 * The silc_server_free_client_data now checks whether there is
7058 pending outgoing traffic for the client and purges the data to
7059 the network before removing the client entry.
7061 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7063 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
7064 an client is killed from the SILC Network. Updated the protocol
7067 Added new function silc_server_send_notify_killed to the
7068 silcd/packet_send.[ch].
7070 * Added function silc_server_packet_relay_notify to relay notify
7071 packets that are destined directly to a client. In this case
7072 the server does not process the notify packets but merely relays
7073 it to the client. Affected file silcd/packet_send.[ch].
7075 Added also silc_server_packet_process_relay_notify to check
7076 whereto relay the notify. Affected file is
7077 silcd/packet_receive.[ch].
7079 * Implemented the KILL command to the server.
7083 * Added the backup schema desgined last fall to the protocol
7084 specs for everyone to see. The specification is in the
7085 *-spec-xx.txt draft and the packet type definitions for the
7086 backup routers is in *-pp-xx.txt draft. Thusly, added also
7087 new packet type SILC_PACKET_CELL_ROUTERS.
7089 * A big security problem in the implementation discovered. The
7090 signoff of an client did not cause new channel key generation
7091 which it of course should've done. The channel keys must be
7092 always re-generated when client leaves (or signoffs) the channel.
7093 The silc_server_remove_from_channels funtion now handles
7094 the channel key re-generation.
7096 * Added `sender' argument to the silc_server_send_notify_on_channels
7097 to not to send the client provided as argument. Affected file
7098 silcd/packet_send.[ch].
7100 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7102 * Implemented OPER and SILCOPER commands into the server and
7105 * Added silc_auth_verify and silc_auth_verify_data to verify
7106 the authentication directly from the authentication payload.
7107 It supports verifying both passphrase and public key based
7108 authentication. Affected file lib/silccore/silcauth.[ch].
7110 * Added `hash' field to the SilcIDListData structure. It is the
7111 hash negotiated in the SKE protocol. Affected file is
7114 * Slight redesigning of the SilcAuthPayload handling routines.
7115 Do not send SilcPKCS but SilcPublicKey as argument.
7117 * Implemented the public key authentication support to the
7118 serverconfig. The public key is loaded from the provided path
7119 and saved as authentication data to void * pointer. Thus,
7120 changed the unsigned char *auth_data to void *auth_data;
7122 * Fixed SHUTDOWN command to send the reply before the server
7123 is shutdown. :) Affected file silcd/command.c.
7125 * Fixed fatal bug in CONNECT command. The hostname was invalid
7126 memory and server crashed. Affected file silcd/command.c.
7128 * Fixed fatal bug in CLOSE command. The server_entry became
7129 invalid but was referenced later in the command. Affected file
7132 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7134 * Fixed fatal bug in failure packet handling. Server ignored
7135 the failure and thus crashed when it came.
7139 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7141 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
7142 that the command may be executed only once in (about) 2 seconds.
7143 The old SILC_CF_LAG flag is same but allows command bursts up
7144 to five before limiting.
7146 Added the support for CF_LAG and CF_LAG_STRICT flags to the
7147 server code. Various commands now includes the CF_LAG_STRICT
7148 flag to disallow any kind of miss-use of the command.
7150 * Fixed the silc_buffer_unformat to not to allocate any data
7151 if the length of the data is zero. It used to allocate the
7152 length + 1. Affected file lib/silcutil/silcbuffmt.c.
7154 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7156 * Changed the format of AdminConnection configuration section
7157 in the server. Added username of the admin to the format.
7158 Affected files silcd/serverconfig.[ch].
7160 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
7161 to return admin configuration data by host, username and/or
7164 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7166 * Implemented WHOWAS command to the server. Added the functions:
7168 silc_server_command_whowas_parse,
7169 silc_server_command_whowas_send_reply,
7170 silc_server_command_whowas_from_client and
7171 silc_server_command_whowas_from_server
7173 * Added <Client ID> argument to the WHOWAS command reply. Updated
7174 the protocol specs accordingly.
7176 * Implemented WHOWAS command and command_reply to the client
7179 Implemented the WHOWAS printing on the user interface.
7181 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7183 * Added new argument to the WHOWAS command reply, the real name.
7184 It is an optional argument. Updated the protocol specs.
7186 * Added SilcIDCacheDestructor callback that is registered when
7187 the SilcIDCache is allocated. The callback is called when
7188 an cache entry in the ID Cache expires, or is purged from the
7189 cache. Added into lib/silccore/idcache.[ch].
7191 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
7192 to destruct the client entries when the cache entry expires.
7193 Other ID Cache's in server and in the client library ignores
7196 * If the ID Cache entry's `expire' field is zero then the entry
7197 never expires. Added boolean `expire' argument to the
7198 silc_idcache_add function in the lib/silccore/idcache.[ch].
7199 If it is TRUE the default expiry value is used.
7201 * Added silc_server_free_client_data_timeout that is registered
7202 when client disconnects. By default for 5 minutes we preserve
7203 the client entry for history - for WHOWAS command.
7205 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7207 * Added support to the server to enforce that commands are not
7208 executed more than once in 2 seconds. If server receives
7209 commands from client more frequently, timeout is registered
7210 to process the commands. Affected file silcd/command.c.
7211 Added new function silc_server_command_process_timeout.
7213 * Changed NICK_NOTIFY handling in client library to check that
7214 if the client's nickname was changed, so there is no need to
7215 resolve anything from the server.
7217 * Removed error printing from the WHOIS and IDENTIFY commands.
7218 If error occurs then it is ignored silently in the client library.
7219 The application, however, may map the received error to
7220 human readable error string. The application currently maps
7221 the NO_SUCH_NICKNAME error to string.
7223 * Made the command status message public to the application. Moved
7224 them from lib/silcclient/command_reply.c to
7225 lib/silcclient/command_reply.h. The application can map the
7226 received command status to the string with the
7227 silc_client_command_status_message function.
7229 * Added check to the server to check that client's ID is same
7230 as the Source ID in the packet the client sent. They must
7233 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7235 * Added dist-bzip hook to the Makefile.am to make bzip2
7236 compressed distributions.
7238 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7240 * Server now enforces the maximum length for the nickname and
7241 the channel as protocol specification dictates. 128 bytes for
7242 nickname and 256 bytes for channel name.
7244 * Moved the WHOIS printing to the application. The client libary
7245 does not print out the WHOIS information anymore, the application
7246 must do it. Renamed silc_client_command_reply_whois_print to
7247 the silc_client_command_reply_whois_save.
7249 The client's idle time is also sent to the application now, and
7250 the idle is shown on screen.
7252 * Added silc_client_command_reply_identify_save to save the
7253 received IDENTIFY entries.
7255 * Do not check for channel private keys in message sending and
7256 reception if the channel does not have the PRIVKEY mode set.
7257 Affected file lib/silclient/client_channel.c.
7259 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7261 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
7262 just surfaced after chaning the JOIN procedure.
7264 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7266 * Added silc_client_get_clients_by_list to get client entries
7267 from Client ID list, that is returned for example by JOIN
7268 and USERS command replies. The application should use this
7269 function for example when JOIN command reply is received to
7270 resolve the clients already on the channel (library does not
7271 do that anymore as USERS command reply is not used in the JOIN
7272 procedure anymore). Affected files lib/silcclient/silcapi.h and
7273 lib/silcclient/idlist.c.
7275 * JOIN command reply and USERS command reply returns now SilcBuffer
7276 pointers instead of unsigned char pointers when returning
7277 the client list and mode list.
7279 * Added <Client ID> argument to the JOIN command reply, mainly
7280 for the server to identify for which client the command was
7281 originally sent. Updated protocol specs accordingly.
7283 * Added SilcDlist private_key pointer to the SilcChannelEntry
7284 in the client to support the channel private keys. Affected
7285 file is lib/silcclient/idlist.h.
7287 * Added SilcChannelPrivateKey argument to the function
7288 silc_client_send_channel_message so that application can choose
7289 to use specific private ke if it wants to. If it is not provided,
7290 the normal channel key is used, unless private keys are set.
7291 In this case the first (key that was added first) is used
7292 as the encryption key.
7294 * Implemented the support for channel private key handling.
7295 Implemented the following functions:
7297 silc_client_add_channel_private_key,
7298 silc_client_del_channel_private_keys,
7299 silc_client_del_channel_private_key,
7300 silc_client_list_channel_private_keys and
7301 silc_client_free_channel_private_keys
7303 Affected file lib/silcclient/client_channel.c.
7305 * Added the support for the private keys in the channel message
7306 sending and encryption and in the message reception and
7307 decryption. Affected funtions are
7308 silc_client_send_channel_message and silc_client_channel_message.
7310 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7312 * Added SKE's key verify callback to the client library's
7313 KE protocol context. Affected files lib/silcclient/protocol.[ch].
7315 * Removed the statement that server (or router) must send USERS
7316 command reply when joining to the channel so that the client
7317 knows who are on the channel. Instead, the client list and
7318 client's mode list is now sent in the JOIN command reply to the
7319 client who joined channel. This is better solution.
7321 * Added function silc_server_get_users_on_channel and function
7322 silc_server_save_users_on_channel to the silcd/server.[ch].
7324 * Removed function silc_server_command_send_users from the
7327 * Do not show topic on the client library anymore. The topic is
7328 sent in the command reply notify to the application and the
7329 application must show the topic now.
7331 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7333 * Added client searching by nickname hash into the IDENTIFY and
7334 WHOIS commands in the server as they were clearly missing from
7335 them. Affected file is silcd/command.c.
7337 * Fixed a bug in private message receiving in the client library.
7338 The remote ID was freed and it wasn't supposed, now it is
7341 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7343 * Minor fix to the channel payload; allocate the data area, as it
7344 needs to be of specific length.
7346 * If the key agreement port is zero then the operating
7347 system will define the bound port. Affected files are
7348 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7350 * Added new function silc_channel_payload_decrypt into the file
7351 lib/silccore/silcchannel.[ch].
7353 * Moved the channel message etc, check from silc_packet_decrypt
7354 to applications. The library calls now a generic
7355 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7356 when the packet is either normal or special. This was done to
7357 allow more wide range of checking that was not allowed when
7358 the code was in library. Now applications can do virtually any
7359 checks to the packet and return to the library the decision how
7360 the packet should be processed. Affected files are
7361 lib/silccore/silcpacket.[ch].
7363 Added silc_server_packet_decrypt_check to the server and
7364 silc_client_packet_decrypt_check to the client library.
7366 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7367 to send with specified source and destination information.
7369 * Channel message delivery between routers was broken after the
7370 channel key distribution was fixed earlier. The channel key
7371 was used be to distributed to other routers as well which is not
7372 allowed by the protocol. Now this is fixed and channel keys
7373 really are cell specific and the channel message delivery between
7374 routers comply with the protocol specification.
7376 * Fixed various commands in server to check also the global list
7377 for the channel entry and not just the local list. The affected
7378 file silcd/command.c.
7380 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7382 * Added assert()s to buffer formatting and unformatting routines
7383 to assert (if --enable-debug) when error occurs. Affected
7384 file: lib/silcutil/silcbuffmt.c.
7386 * Changed to auto-reconnect to check whether the remote host is
7387 router and register the re-connect timeout if it is. It used
7388 to check that whether we are normal server, but router must do
7389 auto-reconnect with another router as well. Affected file
7392 * Removed the [<key len>] option from CMODE command as the cipher
7393 name decides the key length, nowadays. See the defined ciphers
7394 from the protocol specification.
7396 * Added [<hmac>] option to the CMODE command to define the HMAC
7397 for the channel. Added SILC_CMODE_HMAC channel mode.
7399 * Added [<hmac>] option for the JOIN command so that user can
7400 select which HMAC is used to compute the MACs of the channel
7403 * Added Hmac field to the Channel Message Payload. The integrity
7404 of plaintext channel messages are now protected by computing
7405 MAC of the message and attaching the MAC to the payload. The
7406 MAC is encrypted. Now, it is clear that this causes some
7407 overhead to the size of the packet but rationale for this is that
7408 now the receiver can verify whether the channel message decrypted
7409 correctly and also when private keys are set for the channel the
7410 receiver can decrypt the packet with several keys and check from
7411 the MAC which key decrypted the message correctly.
7413 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7414 lib/silccrypt/silccipher.[ch].
7416 * Added silc_hash_len to return the digest length into the
7417 lib/silcrypt/silchash.[ch].
7419 * Rewrote parts of Silc Channel Payload interface in the
7420 lib/silccore/silcchannel.[ch]. The encode function now also
7421 encrypts the packet and parse function decrypts it.
7423 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7425 * Fixed a minor formatting bug in the SKE's key material processing.
7426 It actually might have processed the keys wrong way resulting
7429 * Redefined the mandatory HMAC algorithms and added new algorithms.
7430 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7431 and hmac-md5 truncated to 96 bits. The mandatory is now
7432 hmac-sha1-96. Rest are optional (including the one that used
7433 to be mandatory). Rationale for this is that the truncated HMAC
7434 length is sufficient from security point of view and can actually
7435 make the attack against the HMAC harder. Also, the truncated
7436 HMAC causes less overhead to the packets. See the RFC2104 for
7439 * Added new [hmac] configuration section. The SKE used to use
7440 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7441 is of course wrong. The official names that must be proposed in
7442 the SKE are the ones defined in the protocol specification
7443 (hmac-sha1-96 for example). The user can configure any hmac
7444 using any hash function configured in the [hash] section. At
7445 least, the mandatory must be configured.
7447 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7449 * Added HMAC list to the SKE proposal list. It has now both
7450 hash algorithm list and HMAC list. This makes the protocol
7451 incompatible with previous versions. The SKE now seems to work
7452 the way it is supposed to work, for the first time actually.
7454 * Defined plain Hash algorithms to the protocol specification.
7457 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7459 * Implemented support for key agreement packets into the server.
7460 Added functions silc_server_key_agreement and
7461 silc_server_send_key_agreement. Other than these functions,
7462 server has nothing to do with this packet.
7464 * Added support for private message key packets into the server.
7465 Added functions silc_server_private_message_key and
7466 silc_server_send_private_message_key.
7470 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7471 called in the protocol's final callback instead in the END
7472 protocol state. This makes a little more sense and in the same
7473 time in client we can use the same protocol routines for normal
7474 key exchange and to key agreement packet handling as well.
7476 * Added to both client's and server's KE protocol context the
7477 SilcSKEKeyMaterial pointer to save the key material. We will
7478 bring the key material to the protocol's final callback by doing
7479 this. The final callback must free the key material.
7481 * Added SKE's packet_send callback into client's KE protocol
7482 context so that the caller can choose what packet sending function
7483 is used. This way we can use different packet sending when
7484 doing normal SKE when doing key agreement packet handling (in
7485 the key agreement packet handling we do not want to encrypt
7488 * Implemented the responder side of the key agreement routines
7489 in the client. The client can now bind to specified port and
7490 accept incoming key negotiation. The key material is passed
7491 to the application after the protocol is over.
7493 * Implemented the processing of incoming Key Agreement packet
7494 in the client. Added function silc_client_key_agreement to
7497 * Implemented the intiator side of the key agreement routines
7498 in the client. The client can now initiate key agreement with
7499 another remote client. The key material is passed to the
7500 application after the protocol is over.
7502 * Created client_keyagr.c to include all the key agreement
7505 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7506 SILC_TASK_CALLBACK except that it is not static.
7508 * Created client_notify.c and moved the Notify packet handling
7509 from the client.[ch] into that file.
7511 * Created client_prvmsg.c and moved all private message and
7512 private message key routines from the client.[ch] into that file.
7514 * Create client_channel.c and moved all channel message and
7515 channel private key routines from the client.[ch] into that file.
7517 * Changed silc_client_get_client_by_id_resolve to resolve with
7518 WHOIS command instead of IDENTIFY command, in the file
7519 lib/silclient/idlist.c.
7521 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7523 * Implemented the SKE's responder side to the Client library.
7525 * When FAILURE is received to the protocol do not trust it
7526 blindly. Register a timeout to wait whether the remote closes
7527 the connection as it should do it, only after that process the
7528 actual failure. This was changed to both client and server.
7530 * Added client_internal.h to include some of the structures
7531 there instead of client.h in lib/silcclient/.
7533 * Added function silc_task_unregister_by_callback to unregister
7534 timeouts by the callback function.
7536 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7538 * Some "Incomplete WHOIS info" errors has been appearing on the
7539 log files. Took away the entry->userinfo check from WHOIS
7540 reply sending. The entry->userinfo is now " " if client did not
7541 provide one. I thought this was fixed earlier but something
7542 is wrong still. Let's see if the error still appears.
7544 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7546 * Fixed a minor bug in the login when the channel key is
7547 re-generated in the server. It used to generate the key in
7548 wrong order and thus caused problems in the channel traffic.
7550 * Fixed a minor bug in channel key distsribution after
7551 KICK command. The key was not sent to the router even though
7554 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7556 * Added silc_ske_process_key_material_data as generic routine
7557 to process any key material as the SILC protocol dictates. The
7558 function is used by the actual SKE library but can be used by
7559 applications as well. This relates to the private message keys
7560 and the channel private keys since they must be processed the
7561 same way the normal SILC session keys. The protocol dictates
7562 this. Affected files: lib/silcske/silcske.[ch].
7564 Added also silc_ske_free_key_material to free the
7565 SilcSKEKeyMaterial structure.
7567 * Defined silc_cipher_set_key function to set the key for
7568 cipher without using the object's method function. The affected
7569 files: lib/silccrypt/silccipher.[ch].
7571 * Implemented silc silc_client_add_private_message_key,
7572 silc_client_add_private_message_key_ske,
7573 silc_client_del_private_message_key,
7574 silc_client_list_private_message_keys and
7575 silc_client_free_private_message_keys functions in the
7578 Added functions silc_client_send_private_message_key to send
7579 the Private Message Key payload and silc_client_private_message_key
7580 to handle incoming Private Message Key payload.
7582 * Added Cipher field to the Private Message Key payload to set
7583 the cipher to be used. If ignored, the default cipher defined
7584 in the SILC protocol (aes-256-cbc) is used.
7586 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7588 * Removed lib/silcclient/ops.h file.
7590 Redefined parts of the SILC Client Library API. Created new
7591 file silcapi.h that deprecates the ops.h file and defines the
7592 published Client Library API. Defined also private message key
7593 API and channel private key API into the file.
7595 This is the file that the application must include from the
7596 SILC Client Library. Other files need not be included by
7597 the application anymore.
7599 * Added new key_agreement client operation callback and also
7600 defined the Key Agreement library API for the application.
7602 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7604 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7605 is used by clients to request key negotiation between another
7606 client in the SILC network. If the negotiation is started it
7607 is performed using the SKE protocol. The result of the
7608 negotiation, the secret key material, can be used for example
7609 as private message key.
7611 Implemented the Key Agreement payload into the files
7612 lib/silccore/silauth.[ch].
7614 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7616 * Redefined ciphers for the SILC protocol. Added some new ciphers
7617 and defined the key lengths for the algorithms. Changed the
7618 code accordingly. The default key length is now 256 bits.
7620 * Fixed SKE key distribution function silc_ske_process_key_material
7621 when the key length is more than 128 bits. The default key
7622 length in SILC is now 256 bits.
7624 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7625 to indicate unsupported algorithm.
7627 * Renamed rijndael.c to aes.c and all functions as well.
7629 * Fixed a long standing channel key setting bug in client library.
7630 Weird that it has never surfaced before.
7632 * Fixed bug in channel deletion. If the entire channel is removed
7633 then it must also delete the references of the channel entry
7634 from the client's channel list as the client's channel entry and
7635 the channel's client entry share same memory.
7637 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7639 * Implemented CONNECT and SHUTDOWN commands in the client.
7641 * Implemented CLOSE command to the client.
7643 * Added the function silc_idlist_find_server_by_name into the
7644 files silcd/idlist.[ch].
7646 Added the function silc_idlist_find_server_by_conn into the
7647 files silcd/idlist.[ch].
7649 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7651 * DIE command was renamed to SHUTDOWN. Updated the both code
7654 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7655 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7657 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7660 * Added function silc_server_create_connection function to create
7661 connection to remote router. My server implementation actually
7662 does not allow router to connect to normal server (it expects
7663 that normal server always initiates the connection to the router)
7664 so the CONNECT command is only good for connecting to another
7667 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7669 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7670 or some other client was kicked from the channel.
7672 Implemented the handling of the notify type to both client
7675 Implemented silc_server_send_notify_kicked to send the KICKED
7676 notify. It is used to send it to the server's primary router.
7678 * Implemented the KICK command into server and client.
7680 * Added `query' argument to the silc_idlist_get_client function
7681 to indicate whether to query the client from server or not if
7684 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7685 to indicate that the client is not channel founder.
7689 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7691 * Removed the rng context from SilcPacketContext structure and
7692 changed that the packet routine uses the Global RNG API.
7694 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7696 * Added support for quit message that client can "leave" on the
7697 channel when it quits the SILC. It is ditributed inside the
7698 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7700 Added silc_server_free_client_data that will take the
7701 signoff message as argument.
7703 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7705 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7707 * Updated parts of the protocol specification to keep it up
7710 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7712 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7713 payloads in one packet.
7715 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7716 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7717 use now the new List flag.
7719 * Also deprecated the following packet types: REPLACE_ID,
7720 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7722 * Added list support for Notify packet in server.
7724 * Added silc_server_send_notify_channel_change to send the
7725 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7726 the silc_server_send_replace_id.
7728 * Added silc_server_send_notify_nick_change to send the
7729 NICK_CHANGE notify type. Deprecates the function
7730 silc_server_send_replace_id.
7732 * Added silc_server_send_notify_join to send the JOIN notify type.
7733 Deprecates the function silc_server_send_new_channel_user.
7735 * Added silc_server_send_notify_leave to send LEAVE notify type.
7736 Deprecates the function silc_server_send_remove_channel_user.
7738 * Added silc_server_send_notify_cmode and
7739 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7740 types. Deprecates the silc_server_send_set_mode function.
7742 * Added SERVER_SIGNOFF notify type to indicate that server has
7743 quit. This means that all clients on the channel from that
7744 server will drop. This can be also used when netsplit happens.
7746 Deprecated REMOVE_ID packet type since it is not needed anymore
7749 Added silc_server_send_notify_server_signoff to send the
7750 SERVER_SIGNOFF notify type. Deprecates the function
7751 silc_server_send_remove_id.
7753 Added also silc_server_send_notify_signoff to send the
7754 SIGNOFF notify type.
7756 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7757 SILC protocol from this day on. Changed the protocol
7758 specification as well.
7760 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7761 notify type. It is used between routers to notify about
7762 topic changes on a channel.
7764 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7767 * Partly updated the protocol specification to comply with the
7768 changes now made. It is still though a bit outdated.
7770 * The JOIN notify type now takes one extra argument <Channel ID>.
7771 The packet used to be destined to the channel but now the
7772 JOIN type may be sent as list thus it is impossible to
7773 destine it to any specific channel. By adding this argument
7774 it is again possible.
7776 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7778 * Added CREDITS file. The CHANGES and CREDITS file will appear
7779 in the distribution as well.
7781 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7783 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7784 types in the server's silcd/packet_receive.c.
7786 * Implemented CMODE and CUMODE to work in router environment.
7788 * Fixed minor encoding and decoding buglet from the
7789 lib/silccore/silcmode.c.
7791 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7794 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7796 * Changed all SilcConfigServer* and silc_config_server* to
7797 SilcServerConfig* and silc_server_config*, respectively.
7800 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7802 * Associated the ID (client or server ID) to the Authentication
7803 Payload to avoid any possibility of forging. Updated the
7804 protocol specification and the code accordingly.
7806 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7808 * The RSA key length is now save to the RsaKey context in the
7809 key generation process in lib/silccrypt/rsa.c. The key length
7810 is now used to figure out the maximum size of the block allowed
7811 to be encrypted/signed.
7813 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7814 is equivalent to the silc_mp_mp2bin but does not allocate any
7817 * Changed silc_mp_mp2bin API to take length argument. If it is
7818 non-zero then the buffer is allocated that large. If zero, then
7819 the size is approximated using silc_mp_sizeinbase, which however
7822 * Created Global RNG API which is global RNG that application can
7823 initialize. After initializing, any routine anywhere in the
7824 code (including library) can use RNG without allocating a new
7825 RNG object. This was done to allow this sort of use of the
7826 RNG in code that has no chance to allocate RNG object. All
7827 applications currently allocate this and many routines in the
7828 library use this. Affected file lib/silccrypt/silcrng.[ch].
7830 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7831 it to use the Global RNG API.
7833 * Defined Authentication Payload into protocol specification that
7834 is used during SILC session to authenticate entities. It is
7835 used for example by client to authenticate itself to the server
7836 to obtain server operator privileges.
7838 Implemented this payload into the lib/silccore/silcauth.[ch].
7839 Implemented also routines for public key based authentication
7840 as the new protocol specification dictates.
7842 Moved definitions of different authentication methods from
7843 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7845 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7846 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7847 silc_pkcs_verify_with_hash functions into the file
7848 lib/silccrypt/silcpkcs.[ch].
7850 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7852 * The client entry's userinfo pointer must be always valid.
7853 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7854 will fail since it requires the userinfo. Now, the userinfo
7855 is allocated as "" if actual userinfo does not exist. Actually,
7856 it must exist and it is totally Ok to drop client connections
7857 that does not announce the userinfo. However, we will make
7858 this workaround for now.
7860 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7861 to return the remote port by socket.
7863 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7865 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7866 SILC_SERVER_PENDING_EXEC and added an new macro
7867 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7868 data or when error occurs while processing the pending command.
7870 Added new argument `destructor' into silc_server_command_pending
7871 and to the SilcServerCommandPending object. This destructor is
7872 now called after calling the pending callback or if error occurs
7873 immediately. If error occurs the actual pending callback won't
7874 be called at all - only the destructor. The destructor may be
7875 NULL if destructor is not needed.
7877 All this applies for client library code as well. Similar
7878 changes were made there as well for the pending commands.
7880 In the client, the application must now allocate the
7881 SilcClientCommandContext with the silc_client_command_alloc
7884 * Added reference counter to the SilcServerCommandContext. Added
7885 function silc_server_command_alloc and silc_server_command_dup
7888 Same type of functions added to the client library for the same
7891 * Removed the cmd_ident from IDListData away since it is now
7892 global for all connections. It is the command identifier used
7893 in command sending and with pending commands. The affected file
7896 * Added reference counter to the SilcSocketConnection objecet to
7897 indicate the usage count of the object. The object won't be
7898 freed untill the reference counter hits zero. Currently only
7899 server uses this, and client ignores it. The client must be
7900 set to use this too later. The affected files are
7901 lib/silccore/silcsockconn.[ch]. Added also the function
7902 silc_socket_dup to increase the reference counter.
7904 This was mainly added because it is possible that the socket
7905 is removed underneath of pending command or other async
7906 operation. Now it won't be free'd and proper DISCONNECTING
7907 flags, etc. can be set to avoid sending data to connection that
7908 is not valid anymore.
7910 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7911 the connection. After that it sets SILC_SET_DISCONNECTED.
7912 It is, however, possible that the socket data is not still freed.
7913 The silc_server_packet_process now checks that data is not
7914 read or written to connection that is DISCONNECTED. The socket
7915 get's freed when the reference counter hits zero.
7917 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7919 * Changed the client operation API: channel_message operation's
7920 `sender' is now the client entry of the sender, not the nickname
7921 and the `channel' is the channel entry, not the channel name.
7923 In the private_message operation the `sender' is now also the
7924 client entry of the sender not the nickname.
7926 Affected file is lib/silcclient/ops.h and all applications
7927 using the client operations.
7929 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7931 * Moved the calling of ops->connect() from connect_to_server_final
7932 into receive_new_id functin since that is the point when the
7933 client is actually allowed to send traffic to network. The
7934 affected file is lib/silcclient/client.c.
7936 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7938 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7939 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7940 (if needs broadcasting) instead of broadcasting the packets one
7941 by one which would make a burst in the network traffic.
7943 * Added `broadcast' argument to the functions in silcd/server.[ch]
7944 silc_server_create_new_channel[_with_id] to indicate whether
7945 to send New Channel packet to primary router.
7947 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7949 * Added new function into the silcd/server.[ch] files:
7950 silc_server_create_new_channel_with_id to create new channel with
7951 already existing Channel ID.
7953 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7954 lib/silccore/silcpacket.h. This packet is used t send list of
7955 Set Mode payloads inside one packet. Server uses this to set
7956 the modes for the channels and clients on those channels, that it
7957 announced to the router when it connected to it. The protocol
7958 specification has been updated accordingly.
7960 * The silc_server_new_channel did not handle the packet coming
7961 from normal server as it normally does not send that. However,
7962 when it announces its channels it does send it. Implemented
7963 the support for that.
7965 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7966 into the file lib/silccore/id.h.
7968 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7970 * Fixed memory leaks in the functions silc_idlist_del_client,
7971 silc_idlist_del_channel and silc_idlist_del_server in the file
7972 silcd/idlist.c. All of those leaked like a sieve.
7974 * Fixed some small memory leaks in the client's function
7975 silc_client_notify_by_server.
7977 * Added functions into silcd/server.c: silc_server_announce_clients,
7978 silc_server_announce_channels and silc_server_announce_server.
7979 These functions are used by normal and router server to announce
7980 to its primary router about clients, channels and servers (when
7981 router) that we own. This is done after we've connected to the
7984 These functions effectively implements the following packet types:
7985 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7986 and SILC_PACKET_NEW_ID_LIST.
7988 * Added new functions into the silcd/packet_receive.[ch]:
7989 silc_server_new_id_list, silc_server_new_channel_list and
7990 silc_server_new_channel_user_list to handle the incoming
7991 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7993 * Added support of changing Channel ID in the function
7994 silc_server_replace_id. If the server that announces a channel
7995 to the router already exists in the router (with same name but
7996 with different Channel ID), router is responsible to send
7997 Replace ID packet to the server and force the server to change
7998 the Channel ID to the one router has.
8000 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
8001 client that the Channel ID has been changed by the router. The
8002 normal server sends this to the client. Client must start using
8003 the new Channel ID as the channel's ID.
8005 Implemented handling of this new type into lib/silcclient/client.c
8006 into the function silc_client_notify_by_server.
8008 * Added new function silc_idlist_replace_channel_id into the files
8009 silcd/idlist.[ch] to replace the Channel ID.
8011 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8013 * Call silc_server_command_identify_check always when processing
8014 the IDENTIFY command in silcd/command.c
8016 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8018 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
8019 send keepalive packets. The packet can be sent by clients,
8020 servers and routers.
8022 Added function silc_socket_set_heartbeat into the file
8023 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
8024 If not set, the heartbeat is not performed. The actual
8025 heartbeat is implemented in the low level socket connection
8026 library. However, application is responsible of actually
8029 Added silc_server_send_heartbeat to send the actual heartbeat
8030 packet into silcd/packet_send.[ch]. Server now performs
8031 keepalive with all connections.
8033 * Added silc_task_get_first function into lib/silcutil/silctask.c
8034 to return the timeout task with shortest timeout. There was a bug
8035 in task unregistration that caused problems. TODO has been
8036 updated to include that task system must be rewritten.
8038 * The client library will now resolve the client information when
8039 receiving JOIN notify from server for client that we know but
8040 have incomplete information.
8042 * Rewrote parts of silc_server_remove_from_channels and
8043 silc_server_remove_from_one_channel as they did not remove the
8044 channel in some circumstances even though they should've.
8046 * Encryption problem encountered in server:
8048 The LEAVE command used to send the Channel Key packet to the
8049 router immediately after generating it. However, the code
8050 had earlier sent Remove Channel user packet but not immediately,
8051 ie. it was put to queue. The order of packets in the router
8052 was that Channel Key packet was first and Remove Channel User
8053 packet was second, even though they were encrypted in the
8054 reverse order. For this reason, MAC check failed. Now, this
8055 is fixed by not sending the Channel Key packet immediately but
8056 putting it to queue. However, this is more fundamental problem:
8057 packets that are in queue should actually not be encrypted
8058 because packets that are sent immediately gets encrypted
8059 actually with wrong IV (and thus MAC check fails). So, packets
8060 that are in queue should be encrypted when they are sent to
8061 the wire and not when they put to the queue.
8063 However, the problem is that the current system has not been
8064 designed to work that way. Instead, the packet is encrypted
8065 as soon as possible and left to the queue. The queue is then
8066 just purged into wire. There won't be any fixes for this
8067 any time soon. So, the current semantic for packet sending
8070 o If you send packet to remote host and do not force the send
8071 (the packet will be in queue) then all subsequent packets to the
8072 same remote host must also be put to the queue. Only after the
8073 queue has been purged is it safe again to force the packet
8076 o If you send all packets immediately then it safe to send
8077 any of subsequent packets through the queue, however, after
8078 the first packet is put to queue then any subsequent packets
8079 must also be put to the queue.
8081 Follow these rules and everything works fine.
8083 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8085 * Added new function silc_server_remove_clients_by_server to
8086 remove all client entries from ID list when the server connection
8087 is lost. In this case it is also important to invalidate all
8088 client entires as they hold the invalid server entry. This
8089 fixes fatal bug when server has lost connection and will reconnect
8092 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8094 * Made some sanity checks to silc_server_daemonise like to check
8095 whether the requested user and group actually exists.
8097 * Added sanity check to SKE's silc_ske_responder_finish to check
8098 that the public and private key actually is valid.
8100 * Invalidate the client's nickname when receiving Replace ID
8101 packet and the Client ID is being replaced. This means that the
8102 server will query the nickname if someone needs it (client)
8105 * Sort the ID Cache in client library when the ID Cache data
8106 has changed (needs sorting).
8108 * Do not allow for SILC client to create several connections to
8109 several servers. The client does not support windows right now
8110 and generating multiple connections causes weird behaviour.
8112 Irssi-silc client does support windows and can handle several
8113 connections without problems, see: www.irssi.org and SILC plugin.
8115 * Fixed some places where client was added to the IDList. The
8116 rule of thumb is following (in order to get everything right):
8117 If the client is directly connected local client then the
8118 `connection' argument must be set and `router' argument must be
8119 NULL to silc_idlist_add_client function. If the client is not
8120 directly connected client then the `router' argument must
8121 bet set and the `connection' argument must be NULL to the
8122 silc_idlist_add_client function.
8124 * The funtion silc_server_packet_send_local_channel actually did
8125 not check whether the client was locally connected or not. It
8126 does that now. Fixed a bug related to LEAVE command.
8128 * Fixed Remove Channel User payload parsing bug in server's
8129 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
8131 * The server's silc_server_save_channel_key now checks also the
8132 global ID list for the channel as it might not be in the local
8133 list. Fixed a bug related to LEAVE command.
8135 * Is this the end of the [<unknown>] buglet that has been lurking
8136 around for a long time? A little for loop fix in server's
8137 silc_server_command_whois_parse that is used by both IDENTIFY
8138 and WHOIS command. At least, this was a clear bug and a cause
8139 of one type of [<unknown>] buglet.
8141 * WHOIS and IDENTIFY commands call the function
8142 silc_server_command_[whois/identify]_check function even if
8143 we are not router server.
8145 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8147 * Added --with-gmp configuration option. If set the GMP
8148 is always compiled in the SILC source tree. If not set then
8149 it is checked whether the system has the GMP3 installed. If
8150 it has then the GMP won't be compiled (the system's headers
8151 and library is used), if it doesn't have it then the GMP is
8152 compiled in the SILC source tree.
8154 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8156 * Changed RSA private exponent generation to what PKCS #1
8157 suggests. We try to find the smallest possible d by doing
8158 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
8159 not security fix but optimization.
8161 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8163 * Added new config entry [Identity] to fork the server and run
8164 it as specific user and group. A patch from Bostik.
8166 * Imported Dotconf configuration library into lib/dotconf.
8167 This will be used to create the SILC configuration files later.
8168 It will appear in the distsribution after this commit.
8170 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8172 * A big code auditing weekend happening. Auditing code for
8173 obvious mistakes, bugs and errors. Also, removing any code
8176 Removed files for being obsolete:
8178 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
8179 inline in the file lib/silcutil/silcbuffer.h)
8181 o lib/silcutil/silcbufutil.c (the header has inline versions)
8183 Changed code to fix possible error conditions:
8185 o The buffer formatting routines now check that the destination
8186 buffer really has enough space to add the data. This applies for
8187 both buffer formatting and unformatting
8188 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
8189 unformatting was changed to accomodate following rules:
8190 XXX_*STRING_ALLOC will allocate space for the data into the pointer
8191 sent to the function while XXX_*STRING will not allocate or copy
8192 the data into the buffer. Instead it sets the pointer from the
8193 buffer into the pointer sent as argument (XXX_*STRING used to
8194 require that the pointer must be allocated already). This change
8195 makes this whole thing a bit more consistent and more optimized
8196 (note that the data returned in the unformatting with XXX_*STRING
8197 must not be freed now). The routines return now -1 on error.
8199 o Tried to find all code that use buffer_format and buffer_unformat
8200 and added return value checking to prevent formatting and
8201 especially unformatting errors and possible subsequent fatal
8204 o Changed ske->x and ske->KEY to mallocated pointers in
8205 lib/silcske/silcske.h. Fixed possible data and memory leak.
8207 o Added return value checking to all *_parse* functions. Fixed
8208 many memory leaks as well.
8210 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
8211 so that buffer overflows would not happen. All code now also
8212 checks the return value as it can fail.
8214 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8216 * Added reconnection support to server if the normal server looses
8217 its connection to the router (for example if router is rebooted).
8218 The server performs normal reconnection strategy implemented
8219 to the server. Affected file silcd/server.c.
8221 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8223 * Added new packet type SILC_PACKET_SET_MODE that is used to
8224 distribute the information about changed modes (for clients,
8225 channels and clients channel modes) to all routers in the
8226 network. Updated the protocol specification accordingly.
8228 Added functions into silcd/packet_send.c and
8229 silcd/packet_receive.c: silc_server_send_set_mode,
8230 silc_server_set_mode.
8232 Added new files silcmode.[ch] into lib/silccore that implements
8233 the encoding and decoding of Set Mode Payload. Added new type
8234 SilcSetModePayload. Moved the definitions of different modes
8235 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
8237 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8239 * Oops, a little mistake in server's connection authentication
8240 protocol. The protocol is not ended with FAILURE but with
8241 SUCCESS if the authentication is Ok. :) Affected file is
8244 * Implemented NICK_CHANGE notify handling in server in the file
8245 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
8246 the local clients on the channel. After the changing nickname
8247 in router environment snhould work and the [<unknown>] nickname
8248 should appear no more.
8250 The silc_server_replace_id function that receives the Replace ID
8251 payload now sends the NICK_CHANGE notify type also in the file
8252 silcd/packet_receive.c
8254 * Changed WHOIS and IDENTIFY command to support the maximum amount
8255 of arguments defined in protocol specs (3328 arguments). This
8256 fixed a bug that caused problems when there were more than three
8259 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8261 * Added extra parameter, command identifier, to the
8262 silc_client_send_command so that explicit command identifier
8265 Changed that ID list routines uses specific command identifier
8266 when sending WHOIS/IDENTIFY requests to the server so that they
8267 can be identified when the reply comes back.
8269 Affected files lib/silcclient/command.[ch],
8270 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
8272 * Added `sender' argument to silc_server_packet_send_to_channel
8273 to indicaet the sender who originally sent the packet to us
8274 that we are now re-sending. Ignored if NULL. Affected file
8275 silcd/packet_send.[ch].
8277 * Added some server statistics support in silcd/server_internal.h
8278 SilcServerStatistics structure and around the server code. Also
8279 send some nice statistics information when client is connecting
8282 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8284 * Fixed channel ID decoding in server's JOIN command reply in
8285 silcd/command_reply.c
8287 * Fixed braodcasting of replace ID payload to not to send it if
8288 we are standalone server in silcd/packet_receive.c.
8290 * Fixed all channel message sending routines to not to send
8291 packets to clients that has router set, since they are routed
8292 separately in the same function earlier. Affects file
8293 silcd/packet_send.c and all channel packet sending functions.
8295 * In USERS reply, res_argv[i] are not allocated, the table
8296 is allocated. Thus changed that free the table, not its
8299 * In server's whois_check and identify_check if the client is
8300 locally connected do not send any WHOIS commands - they are not
8303 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8305 * Fixed some minor bugs in client when sending WHOIS command. The
8306 arguments was in wrong order.
8308 * Removed statis function add_to_channel from server in
8309 silcd/command.c that was previously used with the joining but
8312 * Tested USERS command in router environment successfully with two
8313 routers, two servers and two clients.
8315 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8317 * Reorganized the USERS command and command reply in client library
8318 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
8319 When the command is given by user we register a pending command
8320 callback that will reprocess the command after the reply has been
8321 received from the server. When reprocessing the packet we then
8322 display the information. Thus, the USERS information is displayed
8323 now in the command callback instead of in the command reply
8324 callback. The processing of the command is same as previously
8325 when server has sent the command reply in the JOINing process.
8327 * Added to USERS command in silcd/command_reply.c to join the client,
8328 we didn't use to know about, to the channel after we've created
8329 a client entry for it. Also, for clienet we did know already still
8330 check whether it is on the channel or not and add it if not.
8332 * Removed silc_server_command_join_notify as the function and its
8335 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8337 * Changed the client's pending command handling to the same as the
8338 server's pending command handling. It is also now possible to
8339 execute command reply functions from other command reply
8340 function as the function callbacks for commands and command
8341 replies are one and same. The pending commands are not static
8342 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8343 in client connection context. Thus, pending commands are server
8344 connection specific as it is convenient.
8346 Changed the function silc_client_command_pending and
8347 silc_client_command_pending_del and added new function
8348 silc_client_command_pending_check. Removed the
8349 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8352 * Added cmd_ident, current command identifier, to the client
8353 connection context in lib/silcclient/client.h to keep track on
8354 command identifiers used in command sending. Client's command reply
8355 function handling now supports the mandatory command identifiers.
8357 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8358 funtions in client to fully support pending command callbacks.
8360 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8361 as one of the arguments to the application in the command reply
8364 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8365 before first releasing SILC but came back. Now it is removed again
8366 and should come back nomore. The FORWARDED flag was used only
8367 by the JOINing procedure by forwarding the command packet to router.
8368 Now, the JOINing procedure has been changed to more generic (due
8369 to various router environment issues) and FORWARDED is not needed
8370 anymore for anything. The protocol specification is yet to be
8373 Now, removed silc_server_packet_forward from server and the flag
8374 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8376 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8378 * Renamed NAMES command to USERS command. The NAMES was named that
8379 due to historical reasons. Now it is renamed. Also, rewrote
8380 parts of the USERS command. The nickname list is not sent anymore
8381 by the server. Only Client ID and mode lists are sent in the USERS
8382 command. Changed this also to the protocol specification.
8384 The client now resolves the names and stuff after it receives
8385 the USERS list from the server when joining to the channel.
8387 * WHOIS and IDENTIFY commands has been changed to support multiple
8388 Client ID's per command. One can now search for multiple users
8389 in the network by sending only one WHOIS or IDENTIFY command.
8390 Changed the code and the protocol specifications.
8392 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8393 uses silc_server_command_whois_parse to parse the request. */
8395 * If normal server, do not parse the WHOIS and IDENTIFY requests
8396 before sending it to the router. Saves some time.
8398 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8400 * Fixed JOIN command on client library. Wrong number of arguments
8401 used to crash the client.
8403 * Added silc_server_channel_has_global function to check whether
8404 channel has global users or not.
8406 * Added silc_server_channel_has_local function to check whether channel
8407 has locally connected clients on the channel.
8409 * The silc_server_remove_from_one_channel now checks whether the
8410 channel has global users or not after given client was removed from
8411 the channel. It also checks whether the channel has local clients
8412 on the channel anymore. If it does not have then the channel entry
8413 is removed as it is not needed anymore.
8415 * The silc_server_notify now checks on JOIN notify whether the joining
8416 client is one of locally connected or global. If it is global then
8417 the channel has now global users on the channel and that is marked
8418 to the channel entry. Also, it now saves the global client to
8419 global list who is joining and JOINs it to the channel. This is
8420 for normal server, that is.
8422 Changed silc_server_send_notify_on_channel,
8423 silc_server_packet_relay_to_channel and
8424 silc_server_packet_send_to_channel check if we are normal server
8425 and client has router set (ie. global client) do not send the
8426 message to that client, as it is already routed to our router.
8428 * Implemented LEAVE notify type handling in silc_server_notify
8431 * Tested LEAVE command in router environment successfully. Tested
8432 with two routers, two servers and two clients.
8436 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8438 * Implemented SIGNOFF notify type handling in silc_server_notify
8441 * silc_server_remove_id now removes the client entry from all channels
8442 it has joined and thusly sends SIGNOFF notify type.
8444 * Rewrote the NAMES list generation in server by removing two excess
8445 loops. The lists are created now inside one loop.
8447 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8449 * silc_server_remove_channel_user checks now also global list
8450 for channel and client.
8452 * silc_server_new_channel_user checks now both local and global
8453 list for channel and client. Fixed a bug in client id decoding.
8454 Used to decode wrong buffer.
8456 * silc_server_channel_message checks now both local and global
8457 list for channel entry.
8459 * Tested channel joining (hence JOIN) in router environment
8460 successfully. Tested with two routers, two servers and two
8463 * Tested channel message sending in router environment successfully.
8465 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8467 * Added silc_server_save_channel_key into server.[ch] to save the
8468 received channel key in Channel Key payload processing. It is
8469 also used in JOIN command reply handling.
8471 Equivalent function silc_client_save_channel_key added into
8472 client.[ch] into client library.
8474 * Changed JOIN command reply to send information whether the channel
8475 was created or not (is existing already) and the channel key
8476 payload. Changed protocol specs accordingly.
8478 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8479 the request was sent by ID and not by nickname. Crashed on
8482 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8484 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8485 now correctly save the received data.
8487 * silc_server_free_sock_user_data now notifies routers in the
8488 network about entities leaving the network.
8490 At the same time implemented functions silc_server_remove_id
8491 and silc_server_send_remove_id to receive and send REMOVE_ID
8492 packets. The packet is used to notify routers in the network
8493 about leaving entities. The ID removed will become invalid in
8496 * Added function silc_idlist_del_server into server. Removes and
8497 free's server entry from ID list.
8499 * silc_server_private_message function now checks, if we are router,
8500 that the destination ID really is valid ID, naturally.
8502 * In router when NEW_ID packet is received (for new client) the
8503 hash of the Client ID is saved in the ID Cache but the
8504 client->nickname is set to NULL, instead of putting the hash
8507 IDENTIFY command now also checks that client->nickname must be
8508 valid. If it is not if will request the data from the server who
8509 owns the client. Added new function
8510 silc_server_command_identify_check.
8512 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8513 to set the command to already allocated Command Payload.
8515 * Tested private message sending in router environment with two
8516 routers, two servers and two clients. Fixed minor bugs and now
8519 * Fixed segfault from client's NAMES command. Used to crash if
8522 * Forwarded packets must not be routed even if it is not destined
8523 to the receiver. Changed server code comply with this.
8525 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8527 * Added `require_reverse_mapping' boolean value to ServerParams
8528 structure. If TRUE (not default) the server will require that
8529 the connecting host has fully qualified domain name.
8531 If the reverse mapping is not required and hostname could not be
8532 found the IP address is used as hostname.
8534 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8536 * Implemented version string checking to both client and server.
8537 The check is incomplete currently due to the abnormal version
8538 strings used in development version of SILC.
8540 * Changed all command functions in server to use the new
8543 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8545 * Changed char *data to unsigned char *data in ID Cache system to
8546 support binary data as ID Cache data. Changed code to support
8547 binary data in lib/silccore/idcache.c.
8549 * Renamed silc_server_packet_relay_command_reply to
8550 silc_server_command_reply as it is normal packet receiving
8551 function. Rewrote the function to accept command replys for
8552 servers and not only for clients.
8554 * Mark remote router always as registered server if we are connecting
8555 to it. Otherwise, commands sent by the router to us are ignored.
8557 * All ID List find routines now returns the ID Cache Entry pointer
8558 as well if requested.
8560 * WHOIS command works now in router environment, tested with two
8561 routers, two servers and two clients.
8563 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8564 in router environment (as it is almost equivalent to WHOIS) but
8565 hasn't been tested thoroughly. Added new functions:
8567 silc_server_command_identify_parse
8568 silc_server_command_identify_send_reply
8569 silc_server_command_identify_from_client
8570 silc_server_command_identify_from_server
8572 * Disabled route cache adding because adding two different ID's with
8573 same IP replaces the old cache entry thus giving wrong route.
8574 The entry->router->connection is always the fastest route anyway
8575 so route cache may not be needed. Of course, new routes maybe
8576 established after receiving the ID when the entry->router->connection
8577 might not be anymore the most optimal.
8579 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8581 * Add route cache for received ID for fast routing.
8583 * Added silc_server_packet_route to route received packet on router
8584 that is not destined to us.
8586 * Renamed silc_server_get_route to silc_server_route_get.
8588 * Added id_string and id_string_len fields into SilcServer to
8589 include encoded ServerID for fast comparing without excess
8590 encoding of the ID's.
8592 * Cleaned up WHOIS command on server side. Added following static
8595 silc_server_command_whois_parse
8596 silc_server_command_whois_check
8597 silc_server_command_whois_send_reply
8598 silc_server_command_whois_from_client
8599 silc_server_command_whois_from_server
8601 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8602 arguments in command replies. All command functions should be
8603 updated to use this macro.
8605 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8607 * Minor typo fixes on command reply handling on server.
8609 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8611 * Added silc_server_command_add_to_channel internal routine to add
8612 the client to the channel after router has created the channel and
8613 sent command reply to the server.
8615 * Added generic silc_server_send_command to send any command from
8618 * Use static buffer with ID rendering instead of duplicating data.
8620 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8622 * Fixed a channel user mode bug when joining to a channel server gave
8623 everybody channel founder rights, oops.
8625 * We mark ourselves as the router of the incoming server connection
8626 if we are router ourselves. This way we can check in some packet
8627 sending functions whether it is locally connected server. For
8628 incoming router connections we put NULL.
8630 * For router sending packets locally means now always sending the
8631 packet cell wide; to local clients and local servers. For normal
8632 server sending packet locally means sending it to only local
8635 * Fixed the JOIN command to really work in router environment. If the
8636 channel is created it is always created by the router. Router is
8637 also responsible of making the initial joining to the channel,
8638 sending JOIN notify to the sending server and distributing
8639 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8640 does not exist server doesn't do anything else but forward the
8641 command to the router which performs everything.
8643 * Added silc_server_send_channel_key function to send the Channel Key
8646 * Added silc_server_create_channel_key to create new channel key. The
8647 channel key is now re-generated everytime someone joins or leaves
8648 a channel, as protocol dictates. Note: channel->key_len is the
8651 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8653 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8654 packet_receive.[ch] to separate packet sending and receiving
8655 routines. The server.[ch] now includes everything else including
8656 actual packet processing (writing and reading data) and other
8659 Renamed silc_server_private_message_send_internal to
8660 silc_server_send_private_message. The routine is still though
8661 used only to relay private messages as server does not send
8662 private messages itself.
8664 Renamed silc_server_new_channel to silc_server_create_new_channel
8665 and added new function sicl_server_new_channel that handles the
8666 incoming New Channel packet. Added also new sending function
8667 silc_server_send_new_channel to send New Channel Payload.
8669 * Added new function silc_server_notify to process incoming notify
8670 packet to the server/router. Server may then relay the notify
8671 to clients if needed.
8673 * Added new function silc_server_new_channel_user to process incoming
8674 New Channel User packet. Router will redistribute the packet and
8675 send JOIN notify to its local clients and locally connected servers
8676 if needed. Normal server will send JOIN notify to its local client
8677 on same channel when received this packet. Added also corresponding
8678 sending function silc_server_send_new_channel_user to sent the
8681 * Added boolean route argument to send_notif_to_channel and
8682 packet_send_to_channel functions to attempt to route the packet
8683 if it is TRUE and send only locally if it is FALSE.
8685 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8687 * silc_server_replace_id now broadcasts the received replace ID
8688 packet if it is not broadcast packet already. The router must
8689 broadcast to inform other routers about changed ID.
8691 * Added backpointer to server's router into SilcServer context in
8692 silcd/server_internal.h.
8694 * Fixed silc_server_packet_broadcast to send correct broadcast
8697 * The channel key is now distributed to the local client as soon
8698 as it is received from the router (in router environment) so that
8699 no other packet may be sent for the channel until client has
8702 * silc_server_remove_channel_user now broadcasts the received
8703 Remove Channel User packet if it is not broadcast packet already.
8704 The router must broadcast to inform other routers about removed
8707 * Added users field into SilcPacketContext that is a reference count
8708 of the context. One can increase the reference count by calling
8709 silc_packet_context_dup which is now changed to just increase the
8710 reference count instead of duplicating the data. The reference
8711 count is decresed by calling silc_packet_context_free that will
8712 free the data after the reference count hits zero.
8714 For now on the packet context and everything allocated into it
8715 (including the raw packet from network) must be freed by calling
8716 the new silc_packet_context_free function. Added also new function
8717 silc_packet_context_alloc that must be used now to allocate the
8718 context. This also means that if a routine is asynchronous from
8719 silc_[client/server]_packet_parse_type the packet context must
8720 be duplicated by calling silc_packet_context_dup. Otherwise it
8721 gets free'd after silc_[client/server]_packet_parse_type returns.
8722 Also, one must remember that if packet is duplicated then its
8723 reference count must be decresed by calling the free function as
8724 many times as it was duplicated.
8726 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8727 from both client and server.
8729 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8731 * Made joining to a channel working in router environment.
8733 * Cleaned up JOIN command on server side and create function
8734 silc_server_command_join_channel internal routine to make the
8737 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8739 * Changed silc_command_pending list to SilcDList. Also, added
8740 `ident' field to SilcServerCommandPending structure to identify
8741 the reply and to call correct callback.
8743 Added silc_server_command_pending_check function to replace the
8744 corresnponding macro. The silc_command_pending list is not
8747 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8748 to set identifier to previously allocated Command Payload. It
8749 is used to set identifier for command when resending Command
8752 * Added silc_command_payload_encode_payload to encode Command
8753 Payload buffer from SilcCommandPayload structure.
8755 * Added silc_argument_payload_encode_payload to encode Argument
8756 payload buffer from SilcArgumentPayload structure.
8758 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8760 * Changed WHOIS command to support router connection on server side.
8761 The whois request is always sent to router unless the server is
8762 standalone server. After server has received the reply from the
8763 router will it send the reply to the client.
8765 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8766 broadcast received broadcast packet. The function is used only
8767 by router. The broadcast packet is always sent to the router's
8770 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8771 render given ID to printable string, for log files for example.
8773 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8775 * Made basic router to router connections working. At least they
8776 can now connect to each other but nothing really works the way
8777 they are supposed - yet.
8779 * Added new initiator token to RouterConnection configuration
8780 file in silcd/serverconfig.[ch]. It is used to tell whether we
8781 are the initiator to the remote router or whether we'll expect
8782 the other end to connect.
8784 * Moved registering of listener task to silc_server_init, hence
8785 the server starts listenning as soon as it is run, even if it
8786 does not have connections to other routers. Let's see how well
8789 * Changed default connection retry timeouts for more suitable in
8792 * Removed cipher and such arguments from silc_idlist_add_client
8793 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8794 Added new function silc_idlist_add_data to add the keys and stuff
8797 * Added SilcIDListData structure and added it to SilcClientEntry
8798 and SilcServerEntry as their first field in the structure. This
8799 way we can explicitly cast the ID entries to the SilcIDListData
8800 structure and get common data for the entries. In past, we had
8801 to first check what type of connection it is and then cast it to
8802 correct ID entry type. Now, we can directly cast the opaque
8803 pointer to the SilcIDListData (no matter what ID entry it actually
8804 is) and get the data needed.
8806 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8808 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8809 in some circumstances even if threre were timeout tasks, though not
8810 IO tasks, but tasks anyway. Now fixed.
8812 * Defined SilcServerConnection structure to hold connection specific
8813 stuff about directly connected servers and routers. The definition
8814 is currently in silcd/server_internal.h. I thought about having
8815 a bit more important role fro this struct but for now it is used
8816 only when connecting to other server (or router actually).
8818 * Added connecting retry support in server when connecting to
8819 router(s). The retry feature implement exponential backoff
8820 algorithm. Also, added SilcServerParams structure to hold default
8821 parameters for server. For now, it include these retry settings
8822 and are hard coded. After server is moded to be as Silc Server
8823 Library this structure will be more important.
8825 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8827 * Changed client librarys channel->clients table to SilcList and
8828 changed code accordingly.
8830 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8832 * Changed client's channel table to SilcList and changed code
8833 accordingly. Also changed SilcChannelClientEntry to include back-
8834 pointer to the channel so that client entry can use that structure
8835 as list as well and we have fast cross-reference to the channel.
8836 This change dramatically decreased the complexity of channel
8837 handling with client entry and vice versa (removed one extra
8838 loop when searching for channel entry from many functions).
8840 * Changed server->sim from table to SilcDList and changed code
8843 * NAMES command can now be used from user interface. It will show
8844 the user list on the channel, neatly.
8846 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8847 Code now saves realname of the user if it becomes available.
8849 * Renamed configure.in to configure.in.pre and made ./prepare
8850 script to automatically add correct version string to
8851 configure.in which it creates from configure.in.pre.
8853 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8855 * NAMES command reply now shows users mode with the nickname when
8858 * Moved silc_client_ch[u]mode[_char] functions from
8859 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8860 place sucks, they are utility functions and should be in some
8863 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8865 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8868 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8872 * Added TRQ (efficient deque and list library) into lib/trq. This is
8873 a very good list library that is currently used in the SILC. Defined
8874 SilcList API over the library because I didn't like the API very
8875 much. See lib/trq/silclist.h for the API and examples of how to
8876 use the API. Fixed various places in the code to use the new
8877 SilcList API. The SilcList is meant for lists that has a structure
8878 already defined as a list. It is not suitable to add just some
8879 context to the list (in TRQ, the context is the list actually).
8881 So, I defined SilcDList that can be used for the purpose where
8882 predefined list structure does not exit. This can be used as
8883 such list. Now some context just can be added to the SilcDList.
8884 Currently this list is not used in the SILC just yet, though there
8885 are a lot places where this can replace dynamically allocated
8886 tables and I will fix these places, later, to use SilcDList.
8887 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8888 and use TRQ internally).
8890 Also fixed some annoying warning messages that the original TRQ
8891 code generated. Also minor changes to TRQ's Makefile.in.
8893 * Added support for querying by Client ID to both WHOIS and
8894 IDENTIFY commands into server, as required by the protocol.
8896 * Removed method function pointers from SilcBuffer structure. They
8897 weren't used to anything and just increased the context size for
8898 no good reason. This change also made silc_buffer_alloc and
8899 silc_buffer_free functions inline functions.
8901 * Disabled command flooding detection support until it's fixed so
8902 that it accepts commands in but does not execute them more than once
8905 * Added silc_net_localhost(), to return local hostname, into
8906 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8907 that must be initialized before calling silc_client_init.
8909 * Added new function: silc_server_send_notify_on_channels to send
8910 notify messages to all channels client has joined. It is assured
8911 that the message is sent only once per client.
8913 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8914 lib/silcutil/silcutil.[ch] as silc_format function. The new
8915 function is generic and is used by server as well, not only by
8916 the logging routines.
8918 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8919 the provided version string was not acceptable. Added new function:
8920 silc_ske_check_version into lib/silcske/silcske.h. The function
8921 must be implemented by the application (client or server) and it
8922 does not reside in the SKE library. The function checks the version
8923 string remote end sent.
8925 * Added back pointers (to opaque context and to SilcSocketConnection)
8926 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8928 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8929 duplicate packet context structure.
8931 * Changed `notify' client operation to send same arguments as client
8932 receives from server except for ID's. ID's are mapped to correct
8933 ID entry and that is returned. Also, if channel entry is not sent
8934 by server but the notify is for channel the channel entry is sent
8935 to application (otherwise application doesn't know that it is for
8936 channel (library gets it from packet's Destination ID)).
8938 * Added silc_client_remove_from_channels into client library to
8939 remove a client from all channels it has joined to. Used when
8940 received SIGNOFF notify from server. Added also new function
8941 silc_client_replace_from_channels to replace old ID entry with
8942 new ID entry on all channels. Used when received NICK_CHANGE
8945 * Fixed ID Cache list handling in silc_idlist_get_client in
8946 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8947 to get (or query) client by ID.
8949 * Updated TODO list.
8951 * Added connection authentication status message defined by the
8952 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8953 support for these into the code in client and server side.
8955 * Added generic function silc_client_send_command to send any command
8956 with variable argument list. Application should use this function
8957 to send commands if the command functions provided by the library
8958 does not suite for the application's user interface needs.
8960 * Added new `failure' client operation. Application is notified about
8961 received failure packet if client is executing a protocol. In this
8962 case the protocol's execution has failed.
8964 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8965 is required by the protocol.
8967 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8968 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8971 * Added status flag to SilcSKE object to indicate realtime status
8972 of the SKE protocol.
8974 * Application receives now exactly same command reply arguments as
8975 the library receives from server. However, if ID is received the
8976 corresponding ID entry is returned to the application (eg. Client
8977 ID is mapped to correct SilcClientEntry entry and that is returned).
8978 Changed command_reply client operation due to this change.
8980 * Changed all ID's in commands and in command replys as ID Payloads.
8981 Change affected both client and server side codes.
8983 All ID's sent in SILC network (with execption of ID's in SILC
8984 Packet header) are sent in ID Payload to support variable length
8987 * Server now notifies nick changes and notifies all clients on
8988 the channels about the new nickname (about the new Client ID,
8991 * Implemented CMODE command to change channel modes. Supports all
8992 channel modes defined by the protocol specs except ban and invite
8993 lists. (Also, private channel key mode is supported but support for
8994 setting private channel key in client is missing, thus, this mode
8995 has no effect on client side (except that server requires that the
8996 client uses private channel key and normal channel traffic does not
8999 Also, invite mode works per se, but INVITE command does not work
9000 yet correctly, so you can set channel as invite only channel but
9001 inviting clients to the channel does not work (it is yet to be
9002 thought what's the best way to do it).
9004 * Added new command SILC_COMMAND_CUMODE to change user mode on the
9005 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
9006 Implemented CUMODE command to change user's mode on the channel.
9007 Supports all modes defined by the protocol specs.
9009 * Added NAMES command reply to return users modes on the channel.
9011 * Removed unnecessary and slow ciphers from lib/silccrypt.
9013 * Set SO_KEEPALIVE option to connection sockets by default.
9015 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
9017 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
9018 redefined the Notify Payload into protocol specs.
9020 * Added silc_id_payload_parse_id to get ID directly from raw
9023 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9025 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
9026 accept searching by Client ID as well.
9028 * Added support for LEAVE and SIGNOFF notify types in client library.
9030 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
9031 to parse ID Payload from raw data.
9033 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9035 * Added flags parameter into silc_ske_assemble_security_properties
9036 function in lib/silcske/silcske.[ch].
9038 * Changed notify client operation to fit better for notify messages
9039 sent by server. The notify payload received from server is now
9040 passed to the application (after parsing it to SilcNotifyPayload).
9041 It is application's responsibility to retrieve the arguments
9042 from the payload and show the message the way it wants. The message
9043 sent by server is implementation specific.
9045 * Changed public keys to comply with the protocol specification.
9046 Old public keys are not supported anymore and are not compatible.
9048 * Removed nickname from Channel Payload as the latest draft removed
9049 it. The client must resolve the nickname from the NAMES command
9050 reply received when it joined the channel.
9052 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
9054 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9056 * Fixed some errors in protocol specification drafts.
9058 * Created lib/silccore/silcnotify.c to implement Notify Payload
9059 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
9060 generic payloads described by protocol specifications. The file
9061 includes implementations for ID Payload and Argument Payload.
9063 * Changed Command Payload implementation to use the new Argument
9064 Payload. Changed command_xxxx_payload to command_payload_xxxx
9065 to comply with SILC coding conventions.
9067 * Added suppport for Argument Payload handling in Notify Payload
9068 implementation as protocol requires it. Added the new support
9069 into server and client lib as well.
9071 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9073 * Added support for multiple nicknames on same channel. [n] is
9074 added locally to the nickname if there are more than one same
9075 nicknames on the channel.
9077 * Server now sends all nicknames that matched WHOIS request.
9078 Client also shows the list received from server.
9080 * Added TOPIC command to client side. User can now set and show
9081 current topic on channel.
9083 * Added MOTD command to client and server. Also, server sends the
9084 motd when client connects to the server.
9086 * Changed version strings to comply ISO 8601.
9088 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9090 * Fixed protocol error handling in client library. It should now
9091 cope even if the SKE fails for some reason.
9093 * Made new protocol specification drafts for submitting to IETF.
9095 * Implemented TOPIC command to server in silcd/command.c.
9097 * Added two new notify types into lib/silccore/silcnotify.h:
9098 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
9099 notify nickname change and topic setting/change on a channel.
9101 * API change of command_reply operation in client library. The
9102 application gets now the status type received from server as well.
9104 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9106 * Removed the function just added to lib/silcutil/silcschedule.[ch].
9108 * Cras fixed and optimized the packet handling even further and
9109 it should work now. Minor change to the prototype of function
9110 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
9112 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9114 * Added new function into lib/silcutil/silcschedule.[ch]:
9115 silc_schedule_with_fd to select() a specified fd. The function
9116 returns after timeout expires or data arrives or goes. The
9117 function is used by packet routines to wait that all data is
9118 received from network.
9120 * Fixed data reading from network in lib/silccore/silcpacket.c.
9121 The code now assures that all data is read from the fd and then
9122 continues packet processing. This was a bug fix since the code
9123 used to drop some data in some circumstances.
9125 * Added new function into lib/silcclient/client.[ch]:
9126 silc_client_start_key_exchange to start key exchange after
9127 connection has been established to server. The code internally
9128 now uses this funtion but its main purpose was to provide it
9129 for applications that perform their own connecting. After
9130 application has created a connection it merely calls this
9131 function to start the key exchange between client and server.
9132 The library takes care of everything else after that.
9134 Updated also lib/silcclient/README to explain the usage of
9137 * Do not send to application information that connection has
9138 been established. Application gets notified it by connect
9141 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9143 * Applied cras's patch to add silc_schedule_one function. The
9144 function runs scheduler once and returns.
9146 * Fixed the scheduler after cras messed it up. The timeout
9147 handling works now as it's supposed to work.
9149 * Added into lib/silccore/ silcnotify.h to include notify
9150 message types support. Changed silc_server_send_notify*
9151 functions, in server.[ch], to support those new notify types.
9152 Added the support for the notify types into client library,
9153 as well. Added new notify client operation into ops.h in
9156 * Changed silc_server_packet_send_to_channel to send normal
9157 packets instead of just channel message packets. The function
9158 is now used to send the notify packets to channels. It is not
9159 used to send channel message packets anymore, as server never
9162 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
9163 va_arg()s as it seems to require it nowadays. I guess, if SILC
9164 is compiled with older va_arg() the new code should work anyway.
9166 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9168 * Splitted core library. Core library (lib/silccore) includes
9169 now only SILC protocol specific core (and common) components.
9170 Created new utility library (lib/silcutil) that includes more
9171 generic purpose stuff. The stuff for util library was taken
9172 from the old core library. This was minor and easy split.
9174 * Created SILC Client Library (lib/silcclient) that includes
9175 implementation of the SILC client without user interface. This
9176 was major move from silc/ directory. The code has been changed
9177 so that it is transparent towards the user interface. The
9178 silc/ directory includes now the same user interface as before
9179 and it uses the new client library. Read lib/silcclient/README.
9180 Basicly, the client library performs everything else related
9181 to SILC except user interface handling. Also, configuration
9182 files are considered to be part of user interface and library
9183 does not handle them.
9185 This change also changed a lot of structures, function naming etc.
9186 Most important change was that SilcClientWindow object was
9187 renamed to SilcClientConnection in the client library. Created
9188 also new file lib/silcclient/ops.h. Also added new files
9189 silc/local_command.[ch] and silc/client_ops.[ch].
9191 All these changes were made to make it easier for user interface
9192 designers to create what ever user interface for the SILC client
9195 It is also expected that the server will be moved to lib
9196 directory as well and SILC Server Library will be created;
9197 sometimes in the future.
9199 * Removed Local commands from lib/silccore/silccommand.h as
9200 they are application specific and new client library does not
9201 handle any of those anymore.
9203 * Several functions moved to lib/silcutil/silcutilc.[ch] from
9204 old client implementation in silc/.
9206 * Added support for callback functions in SILC_LOG_* macros.
9207 Application can now set its own callbacks that will be called
9208 instead of using the default functions that will always print
9209 the debug messages to stderr (or stdout). Also, debugging can
9210 now be disabled by setting silc_debug to FALSE and re-enabled by
9211 setting it to TRUE. Note, that logging will still work even
9212 if debugging is disabled.
9214 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
9215 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
9216 silc_log_reset_debug_callbacks.
9218 * To enable debugging in silc client one must give now -d
9219 option on command line.
9221 * Changed silc_schedule_init to automatically allocate task queues
9222 if they are not allocated before calling it.
9224 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9226 * Added GMP 3.1 into math library.
9228 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9230 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
9231 a channel in SILC network. The packet is used by servers and
9232 routers to notify other routers that user has left a channel.
9233 This little feature was missing until now. Added the feature
9234 to protocol specification as well.
9236 Added functions: silc_server_send_remove_channel_user and
9237 silc_server_remove_channel_user into server.[ch].
9239 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
9240 lib/silccore/silcpacket.h. However, they are not implemented
9243 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9245 * Fixed joining to a channel and sending channel messages
9246 between server and router. The channel message sending should
9247 now work inside a cell.
9249 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9251 * Fixed the private message sending between server and router.
9252 The private message sending should now work inside a cell.
9254 * Added silc_server_replace_id into server.[ch] to replace
9255 existing ID in the SILC network.
9257 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
9258 and silc_idlist_replace_server_id into idlist.[ch] in server.
9260 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9262 * Fixed the server to server connections. Server can again now
9263 connect to router. Router to router connections probably does
9266 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9268 * Added dynamic protocol registering support. Now protocols can
9269 registered and unregistered on the fly. Patch by cras.
9271 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9273 * Added lib/contrib directory to hold routines that some platforms
9274 don't have but are needed by SILC.
9276 * Added getopt.c, getopt1.c and getopt.h from GNU C library
9277 into lin/contrib to provide getopt() and getopt_long() for
9278 those who don't have it.
9280 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9282 * Added AWAY command to client. When away message is set and
9283 client receives a private message packet the client automatically
9284 replies to the sender with the away message.
9286 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
9287 bug seemed to be the cause of recent problems when compiling
9290 * Added version detection support to SKE protocol specification
9291 and added the new changes to the SKE implementation as well.
9292 There were other minor changes in the SKE protocol as well.
9294 Many changes in lib/silcske/silcske.[ch] and in
9295 lib/silcske/payload.[ch].
9297 * Added ^U functionality, clear input line. Patch from cras.
9299 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9301 * Mainly small bugfixes on core library. Fixed some debugging
9302 logging and buffer overflow in silclog.c.
9304 * Updated config.sub and config.guess on the distribution tree.
9306 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9308 * Added command lagging support in server. Client may execute
9309 commands now only once in two seconds.
9311 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9313 * Optimized packet reception. MAC computation and checking is now
9314 also more optimized. A lot previously duplicated code is now
9315 used as generic by both client and server.
9317 * Fixed key pair generation in clientutil.c
9319 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9321 * Added into lib/silccore/silcbufutil.[ch] new function;
9322 silc_buffer_realloc.
9324 * Moved generic packet sending/encryption functions to
9325 lib/silccore/silcpacket.[ch] from client and server. Some
9326 rewriting of the functions.
9328 * Moved all generic packet reception/decryption functions to
9329 lib/silccore/silcpacket.[ch] from client and server. The
9330 packet processing is now much cleaner in both client and server.
9331 These were major changes in both client and server.
9333 * Created many common functions in server to do packet sending.
9334 Previously code were duplicated a lot, this has been removed
9337 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9339 * Rewrote major parts of the ID cache system. Don't know
9340 whether it is better now or not but at least the API is more
9343 * Major rewrite on ID cache stuff on client because of the ID
9344 cache API changes. Added idlist.c to client.
9346 * Also major rewrite on ID cache stuff on server as well.
9347 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9348 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9349 in hand, instead they are all put into the ID cache system now.
9350 All server_idlist_* routines uses ID cache now instead of
9351 traversing its own lists (those lists does not exist anymore).
9352 SilcIDList though still exists. Also, SilcXXXEntry's are
9355 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9357 * Finally made the SKE implementation compliant to the protocol
9358 specification. All mp integers are now binary encoded as
9359 opposed being HEX encoded.
9361 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9364 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9365 functions: silc_[encode/decode]_pem. Also added function
9366 silc_encode_pem_file to PEM encode with newlines ('\n') for
9369 * SILC public keys are now encoded either PEM or binary. Same
9370 option is for private keys as well. By default private keys
9371 are binary encoded and public keys PEM encoded. Silly HEX
9372 encoding were removed.
9374 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9375 function to create fingerprints.
9377 * Fixed a bug in SHA1; does not change the original data anymore.
9379 * Partly implemented INFO command on client and server side.
9380 Fixed CLEAR command. Changes to SERVER command; show current
9381 server(s) when giving command without arguments. Added
9382 VERSION command to client.
9384 * Added check to server that unregistered connections cannot
9385 execute commands (unless it is specificly allowed).
9387 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9389 * Fixed screen refresh.
9391 * Fixed channel joining bug from client. On some circumstances
9392 client tried to join to a channel it had already joined.
9394 * Added public key verification process into client's protocol.c.
9395 The client now verifies the public key from user and saves
9396 it into ~./silc/serverkeys/ directory.
9398 Added into: clientutil.[ch]: silc_client_verify_server_key.
9400 * Changed SKE protocol's silc_ske_initiator_finish function
9401 to accept callback function that verifies the received public
9402 key. Removed old silc_ske_verify_public_key function.
9404 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9406 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9407 silc_pkcs_private_key[_data]_set.
9409 * Made the password and public authentication more cleaner in
9410 server's protocol.c.
9412 * Removed historic and obsolete protocol `channel_auth' from
9413 both client and server.
9415 * Removed wrong way of sending command status messages from
9416 server to client in server's command.c. The old way violated
9417 protocol specification.
9419 Changes to silccore/silccommand.[ch]: removed
9420 silc_command_encode_status_payload -> not needed anymore,
9421 changed silc_command_encode_payload_va to accept extra
9422 argument on variable argument list. The argument type must
9423 now be provided to the function. Also, added new function:
9424 silc_command_encode_reply_payload_va which is same as
9425 normal command_encode_payload_va except command status type
9426 is provided as extra argument.
9428 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9430 * Added ~./silc directory handling. The directory includes the
9431 public and private keys for the client.
9433 Added silc_client_check_silc_dir, silc_client_create_identifier
9434 and silc_client_load_keys.
9436 * Implemented SILC protocol compliant public key. Added public
9437 and private key saving to and loading from files.
9439 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9440 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9441 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9442 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9443 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9445 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9446 silc_pkcs_load_[public/private]_key.
9448 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9450 * Added silc_server_get_route (route.[ch]) to get connection
9451 data for the fastest route for given ID.
9453 * Implemented INVITE command on client and server. The command
9454 were re-defined in the SILC Protocol Specification and the
9455 implementation now complies with the specification.
9457 * Implemented PING command on client and server.
9459 * Implemented NAMES command on client and server. The server side
9460 supports currently only normal server not router server yet.
9461 Some changes to NAMES definition in SILC protocol specification.
9463 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9465 * Implemented LEAVE command on client and server.
9467 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9468 again. This change was made to the protocol as well. Server
9469 should not violate the protocol specification anymore.
9471 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9473 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9474 was tested. SOCKS4 was not but should work anyway.
