124 errors. Added better error printing to SKE library.
125 Affected files lib/silcske/silcske.c, silcske_status.h and
128 * Save the PKCS key length even if only private key is set to
129 SilcPKCS. Affected file lib/silccrypt/silcpkcs.[ch] and rsa.c.
131 * Fixed the usage of silc_pkcs_get_key_len since it returns the
132 length in bits not in bytes. Affected files are
133 lib/silcske/silcske.c, lib/silccore/silcauth.c and
134 silcd/server_query.c.
136 Wed Oct 9 17:22:57 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
138 * Added silc_attribute_payload_encode_data to directly encode
139 the data into the attributes buffer. Renamed function

148 the Requested Attributes from the client. Fixed memory leak
149 in client entry freeing. Affected files silcd/server_query.c
152 * Added Requested Attributes support into SILC Client Library.
153 It is not able to send requested attributes in WHOIS command,
154 and also receive and process requested attributes. Added
155 silc_client_attribute_[add|del] and silc_client_attributes_get
156 functions. Added also `ignore_requested_attributes' to the
157 SilcClientParams to not use attributes in client. Affected
158 files are lib/silcclient/command.c, client_attrs.[ch],
159 silcclient.h, client_internal and client.[ch].
161 * Changed the silc_client_get_client_by_id to support Requested
162 Attributes, it takes them as argument now. Affected file
163 is lib/silcclient/silcclient.h, and idlist.c.
165 * Added -details option to WHOIS command in Irssi SILC Client
166 to support the requested attributes. By default it requests

177 Mon Oct 7 18:25:35 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
179 * Changed the silc_attribute_payload_encode to support list
180 of attributes (function may be called several times to add
181 a new attribute). Removed the silc_attribute_payload_encode_list
182 function. The encoding function now also automatically encodes
183 the data, so the caller does not need to do that. Affected
184 files lib/silccore/silcattrs.[ch].
186 * Added support for replying on behalf of the user to the
187 Requested Attributes in WHOIS command in the server. Affected
188 file silcd/server_query.c.

237 * Resumed client packet handling from server put the resumed
238 client on wrong list on router and caused the client not
239 be present on the network anymore. Now fixed to put the
240 client to correct list. Affected file silcd/packet_receive.c.
242 Wed Sep 18 15:13:48 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
244 * Various cleanup in error message output in config parsing code
245 and in server init code. Fixed error log files containing
246 too many newlines ('\n') in some situations. Affected files are
247 silcd/serverconfig.c, silcd/silcd.c, and silcd/server.c.
249 Wed Sep 18 10:51:23 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
251 * Use the reverse lookupped hostname in client internals
252 instead of one user provided us as remote server name.
253 Affected file lib/silcclient/client.c.
255 Mon Sep 16 12:02:54 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
257 * Added 'app_context' to silc_schedule_init. It is an
258 application specific context that is delivered to application
259 in task callback functions. Affected files are
260 lib/silcutil/silcutil.[ch].
262 * The hb_context in SilcSocketConnection is not freed
263 automatically anymore (application must free it). Freeing
264 it automatic is inconsistent. Affected files are
265 lib/silcutil/silcsockconn.[ch].
267 Sun Sep 15 22:16:19 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
269 * Added support for removing explicitly added client connections
270 in rehash and closing the client connections if they were

273 * Added support for aborting automatically pending commands
274 that never receives the reply (to avoid memory leaks).
275 Added also silc_server_command_pending_timed to set the
276 specific timeout for pending command. Affected files are
277 silcd/command[_reply].[ch].
279 * Added SILC_STATUS_ERR_TIMEDOUT status. Updated protocol
280 specs and lib/silccore/silcstatus.h.
282 Sun Sep 15 12:25:10 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
284 * Changed the silc_get_time to accept time value as argument

286 file lib/silcutil/silcutil.[ch].
288 * Added STATS command to client library and Irssi SILC client.
289 Patch provided by Ville Räsänen <ville.rasanen@iki.fi>.
291 Wed Sep 11 09:22:00 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
293 * Assure that channel key is set before sending it. May
294 crash server otherwise. Affected file silcd/packet_send.c.
296 Tue Sep 10 09:50:08 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
298 * Assure that endless loop cannot happen with detached client
299 resolving on normal server. Added idlist status
300 SILC_IDLIST_STATUS_RESUME_RES. Affected files are
301 silcd/idlist.h and silcd/packet_receive.c.
303 Mon Sep 9 12:18:18 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
305 * Incoming file transfer request cannot use same session as
306 the sending session. This can happen when sending file to
307 yourself. Crashed the client on quit. Affected file
308 lib/silcclient/client_ftp.c. Bug #24.
310 Sun Sep 8 18:39:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
312 * Implemented the draft-riikonen-precense-attrs draft and
313 the Attribute Payload into the lib/silccore/silcattrs.[ch].
315 Sun Sep 8 13:13:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
317 * Distribute the SERVER_SIGNOFF notify also to local backup
318 routers from the primary router. The backup router may not
319 have the signing of local server directly connected and need
320 to know about the signoff. Affected file silcd/server_util.c.
322 * Use the primary router as the origin of the locally connected
323 server when it is disconnecting from the backup router since
324 that's where it really is coming from. Now the clients from
325 the disconnecting server are removed correctly and "shadow"
326 clients are not left to the backup router. Affected file
329 Sat Sep 7 22:26:50 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
331 * If normal server is standalone and found existing but disabled
332 channel, do not re-create the channel since it creates
333 duplicate same channels. Affected file silcd/server.c.
335 * Added anonymous client connections support to server. New
336 "anonymous" configuration option to ConnectionParams section
337 added. If set to true, the username and hostname information
338 of the client will be scrambled and anonymous user mode is
339 set automatically to the user. Affected files are
340 silcd/serverconfig.[ch], silcd/packet_receive.c and server.c.
342 Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
344 * In JOIN notify handling, mark that the cache entry of the
345 client cannot be expired. Can cause crashes on normal
346 server (asserts client->channels). Affected file is
347 silcd/packet_receive.c.
349 * From now on distribution versions are used as protocol versions
350 instead of by default using the Toolkit base version as protocol
351 version. Affected file prepare.
353 * Do not set the locally resolved hostname for local client
354 entry but take what server sends. This way the real hostname
355 is showed in WHOIS for yourself. Affected file is
356 lib/silcclient/idlist.c and lib/silcclient/client.c.
358 * Resolve local info with IDENTIFY when connecting to server.y
360 Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
362 * Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
363 for implied search (not needed on platforms which has native
364 pthreads library). Use --without-pthreads to disable threads.
365 Affected file is configure.in.pre
367 * Fixed --with-iconv on platforms which need to bypass (broken)
368 native iconv(). Affected file is configure.in.pre
370 Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
372 * Moved -C option parsing in Irssi SILC client at same time
373 as other options. The UI was initialized earlier and caused
374 problems on command line. Bug #16. Affected file is
375 irssi/src/silc/core/silc-core.c.
377 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
379 * Added global variable silc_log_timestamp that tells silclog
380 wether to print or not the timestamp in the logging files.
381 Affected file lib/silcutil/silclog.[ch].
383 * Added silcd configuration option Timestamp in the Logging
384 section. Affected file silcd/serverconfig.[ch],
385 doc/example_silcd.conf.in.
387 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
389 * Fixed fingerprint checking to check for entirely empty
390 fingerprint instead of two first bytes when determining
391 if it is set. Bug #18. Affected file silcd/command.c.
393 * Fixed duplicate PKCS name registering to not allow it.
394 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
396 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
398 * Conditionalize non-gcc compiler optimizations for various
399 platforms, enable those commented out. Cleanups.
400 Affected file lib/silcmath/mpi/configure.in
402 Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>
404 * silc_rng_exec_command() left zombie processes if command
405 didn't generate any output. Affected file
406 lib/silccrypt/silcrng.c
408 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
410 * Rewrote iconv checking, introduce --with-iconv for systems
411 which rely on libiconv. Check if iconv() provided by libc
412 is good enough, otherwise demand libiconv. Affected file
415 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
417 * Search for ldopen() also in libc. This enables SIM support
418 on *BSD systems. Based on patch from Alex Zepeda. Affected
419 file configure.in.pre
421 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
423 * Don't call AM_CONDITIONAL conditonally for SILC_THREADS.

427 Sun Aug 4 15:55:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
429 * More fixed for not having purge timeout for global clients
430 that are on channel. Affected files silcd/command_reply.c
433 * Fixed the rekey protocol to work with backup router connections.
434 Rekey packets are now allowed on disabled connections as
435 well. Affected files silcd/packet_send.c and server.c.
437 * Do not switch to be as backup router when shutting down and
438 closing the primary connection. Affected file silcd/server.c.
440 * Fixed memory leaks in backup router deleting. Added
441 silc_server_backup_free to free all data during shutdown of
442 server. Affected files silcd/server_backup.[ch].
444 Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
446 * Do not process commands if the sock->user_data is NULL.
447 Affected file silcd/command.c.
449 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
451 * Fixed buffer overflow and security problems (loosing bits
452 in CFB encryption) in SILC RNG. Problems reported by
453 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
455 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
457 * Added yet more checks that client is not expired on global
458 list if it is on channels. Affected file is
459 silcd/command_reply.c.
461 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
463 * Merged c0ffee's MIME signal patch which adds support for
464 sending also MIME messages in Irssi SILC Client, and handling
465 received MIME messages in a signal (and perhaps doing something
466 to non-textual MIME messages).
468 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
470 * Fixed pending command deletion in server and client library
471 to check the whole list instead of breaking after first found.
472 The affected files are silcd/command.[ch] and
473 lib/silcclient/command.[ch].
475 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
477 * Return NO_SUCH_CHANNEL error in USERS for channel that is
478 secret or private, otherwise it's possible to find out
479 whether a secret channel exists or not. Affected file
482 * If CMODE change fails during the mode setting, assure that
483 the old mode mask is set for the channel back. Affected
484 file silcd/command.c.
486 * Fixed passphrase saving on +a channel on normal server
487 after successful JOIN command. Affected file silcd/command.c.
489 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
491 * Remove server/router operator privileges in DETACH command,
492 since it's possible to resume to server where these
493 privileges would not be allowed for the client. Affected
494 file silcd/command.c.
496 * Do not set to wait for backup in rehash of the server.
497 Affected file silcd/server.c.
499 * Do not check listener sockets when counting how many
500 socket connections we have. Affected file is
503 * Do not announce disconnected clients that are remaining
504 in history (for WHOWAS). This is because SIGNOFF notify
505 for these has been sent earlier already. Affected file
508 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
510 * Buffer overflow with CUMODE command's mode->mode character
511 conversion. Reported by Ville Räsänen. Affected file
512 lib/silcutil/silcutil.c.
514 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
516 * Allow heartbeat packets to go disabled connections anyway.
517 Affected files silcd/server.c and silcd/packet_send.c.
519 * Do not broadcast New Channel packets with List flag set
520 in the packet to backup routers. The router must check
521 for the correctness of the packets before sending them.
522 It is possible that router will have enforce Channel ID
523 change and this would cause desync in the backup router.
524 Affected file silcd/packet_receive.c.
526 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
527 are handled in list parsing. They are not list packets
528 anymore. Affected file silcd/packet_receive.c.
530 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
532 * Stop waiting for backup router through the timeout, not
533 directly after backup router has arrived. Affected file
536 * Do not re-create channel keys and send them when removing
537 clients in server shutdown. Affected files are
538 silcd/server_internal.h and silcd/server_util.c.
540 * Notify distribution to backup routers was missing from
541 the silc_server_send_notify_dest function which caused
542 desyncing problems with backup router. Affected file is
545 * The client's channel removing was working wrong on
546 backup router. It assumed that it doesn't know global
547 information but backup router does know. For this reason
548 it could remove channel when it wasn't supposed to do that.
549 Affected file silcd/server.c and silcd/server_util.c.
551 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
553 * Stop for a couple seconds after badkup router has become
554 primary router. Affected file silcd/server.c.
556 * Added silc_server_remove_servers_by_server, which is used
557 to remove servers originated from some other server. Also
558 clients of those servers can be removed too. Affected file
559 silcd/server_util.[ch].
561 * When removing clients after a server has signed of remove
562 also all servers behind that server (unless they are known
563 to be available locally), and send SERVER_SIGNOFF for each
564 of the server separately. Also the signed off clients are
565 sent now separately per signed off server. The affected files
566 are silcd/server.c and silcd/server_util.[ch].
568 * All servers added with silc_idlist_add_server must always
569 have both "router" and "connection" pointers set. Otherwise,
570 bad server entries may be left around in the cache.
571 Affected file silcd/command_reply.c.
573 * Do not create the channel key in NEW_CHANNEL packet
574 processing if the channel is empty. Affected file
575 silcd/packet_receive.c.
577 * Completed backup router support for standalone routers.
578 Supports also servers in the cell that do not use the backup
581 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
583 * Fixed a bug in silc_string_regexify which did not add '^'
584 at the start of each string, and thus the matching was
585 not explicit. For example ban list iikone@*!*@* would
586 match also "priikone", which is wrong, it would have to be
587 *iikone@*!*@* to match also "priikone". Affected
588 file lib/silcutil/unix/silcunixutil.c.
590 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
592 * Enable all local server connections before updating client
593 caches when we've become backup router. Otherwise, signoff
594 packets may not reach the clients. Affected files are
595 silcd/server.c and silcd/server_util.[ch].
597 * Fixed a bug in version string parsing which could crash
598 the program with specially formatted version string.
599 Bug reported and patch provided by Ville Räsänen. Affected
600 file lib/silcutil/silcutil.c.
602 * Handle the disconnection immediately when DISCONNECT
603 packet is received in server. Affected file silcd/server.c.
605 * Primary router now waits a short time (10 seconds) for
606 backup router connection before accepting any other
607 connection (except local). Affected file silcd/server.c,
610 * Fixed a crash in client libary in NICK_CHANGE notify when
611 NICK_CHANGE arrived for client entry we are resolving
612 currently. Affected file lib/silcclient/client_notify.c.
614 * Call the sconn->callback completion even if error had
615 occurred. Start reconnecting always if connection to
616 primary router fails during backup router protocol.
617 Affected files silcd/server.c and server_backup.c.
619 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
621 * Added functions silc_server_send_opers and
622 silc_server_send_opers_notify to send packets stricly
623 to operators. Added macro SILC_SERVER_SEND_OPERS macro
624 to send variable argument notify to operators.
625 Affected files silcd/packet_send.[ch] and silcd/server.h.
627 * Removed UMODE rights checking with UMODE_CHANGE notify.
628 Affected file silcd/packet_receive.c.
630 * Server/router operator now receives notify when network
631 switches to backup router and when it resumes the use of
632 primary router. Affected file silcd/server.c and
633 silcd/server_backup.c.
635 * Fixed the updating of client information after backup
636 resuming protocol is over; update all except local clients
637 to the new primary router. The affected file is
640 * Added support for closing active connections in rehash
641 that were unconfigured by the user. Supports currently
642 closing server and router connections. Affected file
645 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
647 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
649 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
650 is NULL since seems that on some platforms NULL is allowed
651 and on some it's not. Fallback encoding is used instead.
652 Affected file lib/silcutil/silcstrutil.c.
654 * Fixed statistics updating for incoming server connection
655 which could cause problems when re-connecting. Affected
658 * Preliminary backup router support for standalone router
659 added. Affected files in silcd/.
661 * Mark server connections in backup router disabled before
662 and after backup protocol. Affected file is
663 silcd/server_backup.c.
665 * Added support for reconnecting to remote server connection
666 even if the protocol fails, and if the configuration wants
667 us to keep trying to connect anyway.
669 Server connection is not allowed to backup router if
670 backup router does not have connection to primary router yet.
672 Affected file is silcd/server.c.
674 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
676 * Added silc_client_udpate_server function to update changed
677 server info. Affected file lib/silcclient/idlist.[ch].
679 * Added check for server entries that are being resolved when
680 notify is received. If being resolved, handle the received
681 notify only after it's resolved so that all notifys are
682 handled in same order as received from the server.
684 Added similar resolver check to channel entries. Every
685 notify that cause resolving of any information that affects
686 channel entry marks the channel entry in waiting state.
687 After whatever resolving is over the waiters are signalled
688 and only then the notifys are handled in the same order
689 as delivered from the server.
691 Affected files are lib/silcclient/idlist.[ch], and
694 * Fixed KILLED notify handling in normal server. Affected
695 file silcd/packet_receive.c.
697 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
698 is locally connected, or was locally connected (but may
699 be detached and connection is not active). Added also
700 SILC_IS_LOCAL for checking this status. Affected files
701 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
702 silcd/server.c and silcd/server_internal.h.
704 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
706 * Don't send or handle TOPIC_SET if topic is already set and
707 is same as being set. Affected files silcd/command.c and
708 silcd/packet_receive.c.
710 * Fixed CMODE change rights checking to work correctly when
711 removing modes by operator. Affected file is
714 * Fixed some handling with New Channel packet in router and
715 fixed some CMODE_CHANGE notify handling in server and router.
716 Affected file is silcd/packet_receive.c.
718 * Changed "disconnect" client operation to include the
719 reason of the disconnection and optional disconnection
720 message. Affected file lib/silcclient/silcclient.h.
722 * Made the compilation of lib/contrib/ stuff conditional.
723 Affected files configure.in.pre, lib/contrib/Makefile.am.
725 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
727 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
728 to the sender of the notify too, to avoid situation where two
729 notifys are in the network at the same time going to oppsite
730 directions. Affected file silcd/packet_receice.c.
732 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
734 * Delete the client from channel even if the cilent->id is
735 NULL. It was possible that client was deleted without
736 removing from channels (theoretically at least). Affected
737 file silcd/server.c and silcd/server_util.c.
739 * Free the client data too when resuming is not successful.
740 Affected file silcd/packet_receive.c.
742 * Merged some code from c0ffee's silc-plugin. Affected files
743 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
745 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
746 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
747 to the primary router connection, the other one returns
748 TRUE if packet must be broadcasted to network.
750 * All notifys that are destined to primary router (to network)
751 are now automatically sent to backup routers even if the
752 router is standalone (and has backup router). Affected files
755 * Added --without-irssi and --without-silcd configuration
756 options for disabling the compilation of these applications.
757 Affected file configure.in.pre and prepare.
759 Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
761 * Implemented SILC_STRING_BMP and SILC_STRING_UNIVERSAL for
762 UTF-8 encoding and decoding. Added also new encodings
763 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
765 Added also SILC_STRING_LANGUAGE which is language and charset
766 specific encoder and decoer for those platforms that support
767 iconv(). It can convert the UTF-8 to and from the locale
768 specific character set.
770 Affected file lib/silcutil/silcstrutil.[ch].
772 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.
774 * Added function silc_get_command_name to the file
775 lib/silcutil/silcutil.[ch].

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

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

834 calling the "disconnect" client operation. Affected file
835 lib/silcclient/client.c.
837 * Handle local errors correctly during resuming. Affected
838 file lib/silcclient/client.c.

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

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

1582 * Fixed a bug in server where sending unknown command crashes
1583 the server. Affected file silcd/command.c.
1585 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1587 * Added SILC_PROTOCOLVERSION macro to check protocol version
1588 of a socket connection. The affected file is
1589 lib/silcutil/silcsockconn.h.
1591 * Added better error logging in rekey protocol. Affected file
1594 * Do not check public key types in SKE during rekey. Affected
1595 file lib/silcske/payload.c.
1597 * Fixed the rekey protocol with PFS, which was totally broken.
1598 Affected file silcd/protocol.c.
1600 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1602 * Some client implementations quit network by doing first LEAVE
1603 and then immediately SIGNOFF (like Bombyx). We now do check
1604 after a short time after LEAVE notify and check whether the
1605 client is still valid after LEAVE, and if not we remove it from
1606 cache. Affected file is lib/silcclient/client_notify.c.
1608 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1610 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1611 it's good not to have security holes here.
1613 * Fixed a negative refcount situtuation for the config context.
1614 Affected file is silcd/serverconfig.c.
1616 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1618 * ROBOdoc documented lib/silcutil/silcutil.h.
1620 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1622 * Optimized even more the SilcPacketContext structure. Now
1623 totally saved 16 bytes of memory per context after optimization.
1624 Affected files are lib/silccore/silcpacket.[ch].
1626 * Made strict checks for valid SILC IDs. Affected file is
1627 lib/silccore/silcid.c.
1629 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1631 * Changed the object argument for silc_cipher_register,
1632 silc_hash_register, silc_hmac_register and silc_pkcs_register
1633 to const. Affected files are lib/silccrypt/silccipher.[ch],
1634 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1636 * Changed the silc_get_username and silc_get_real_name to
1637 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1639 * Fixed the Irssi SILC Client to use the silc_get_username and
1640 silc_get_real_name insted of glib routines since the glib
1641 routines only corrupt stack. Fixes the Irssi SILC to work in
1642 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1644 * Fixed the Irssi to not use g_get_home_dir since it crashes
1645 or returns garbage on cygwin and corrupts stack. Added function
1646 get_home_dir to Irssi routines. Affected files are
1647 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1649 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1651 * Made some structure optimizations. SFTP memory FS MemFSEntry
1652 entry structure. Optimized SilcTask structure. Optimized
1653 SilcPacketContext structure.
1655 Affected files lib/silcsftp/sftp_fs_memory.c,
1656 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1658 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1660 * And yet again reverted back the config thing since Johnny
1661 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1664 * Fixed memory leaks from config object. Affected files are
1665 silcd/serverconfig.[ch].
1667 * Added support for adding new connections to the server in rehash.
1668 After rehash they take effect.
1670 Added support for changing the maximum allowed connections in
1671 rehash. The number can grow but going smaller is not supported.
1673 Added function silc_server_num_sockets_by_remote to the
1674 silcd/server_util.[ch].
1676 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1678 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1680 * Added preliminary checking during config parsing for a valid
1681 public/private key and removed further checks in the code.
1682 Affected files are silcd/serverconfig.[ch], server.c.
1684 * Moved functions silc_server_drop() and silc_server_daemonise()
1685 from server.c to silcd.c since they are stricly related to
1686 the application activity.
1688 * Reverted a small part of the automatic ref/unref since
1689 it caused a double unref in some situations. Affected
1690 files are silcd/silcd.[ch], server.c, serverconfig.c.
1692 * Added some .cvsignore files in the lib directory.
1694 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1696 * Fixed silc_net_gethostbyaddr to correctly resolve by
1697 address. Affected file lib/silcutil/silcnet.c.
1699 * Fixed the notify relaying to client. The HMAC to be used
1700 with relayed packets ws wrong and caused decryption failure
1701 at the client end. Affected file is silcd/packet_receive.c.
1703 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1705 * Created new branch silc_protocol_1_0_branch.
1707 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1709 * Changed the silc_server_config_* routines to be SilcServer
1710 independent. They are now officially application specific code
1711 and not part of generic server implementation. Affected files
1712 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1714 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1716 * Added automatic referencing of config context in the
1717 silc_server_config_alloc, and automatic unreferencing in the
1718 silc_server_config_destroy. Affected files are
1719 silcd/serverconfig.[ch], silcd/silcd.c.
1721 * Fixed the silc_log_quick handling in the logging routines.
1722 It didn't log quickly when it was TRUE. Affected file is
1723 lib/silcutil/silclog.c. Also the flush delay was set even
1724 if it was 0 in config file. Affected file is
1725 silcd/serverconfig.c.
1727 * Added support for changing key pair of the server in rehash.
1728 Affected file silcd/server.c.
1730 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1732 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1733 too early, before getting the channel entry. Affected file
1734 is silcd/packet_receive.c.
1736 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1738 * Added functions silc_server_config_[ref/unref], these are used
1739 to prevent that the config object is destroyed.
1741 No longer directly affect global variables silc_log_quick and
1742 silc_log_delay, they are first cached inside the config object
1743 and then applied with silc_server_config_setlogfiles().
1745 silc_server_config_set_defaults() is now internal to
1746 serverconfig.c, there are no reasons to show this internal stuff
1749 Affected files are silcd/serverconfig.[ch].
1751 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1752 fprintf's to stderr, since some code may be executed again after
1753 the server went into the background. Affected files are
1756 * Added rehash support. Added function silc_server_rehash() that
1757 will perform all the basic tasks of the rehashing procedure.
1759 * Added command line option `-x, --hexdump'. This will enable the
1760 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1761 The option `--hexdump' implies `--debug'.
1763 * Fixed a bad bug in the logging APIs (silcutil library) where
1764 the application would crash after calling silc_log_reset_all().
1766 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1768 * Fixed the KICKED notify handling in client library to
1769 correctly remove the channel and all entries from the
1770 channel when I was kicked. This bug crashed the client.
1772 Fixed yet another but in KICKED notify handling to remove
1773 the kicked client correctly from the channel.
1775 Affected file is lib/silcclient/client_notify.c.
1777 * Fixed a minor bug in looking up correct client entry
1778 in KICKED notify in server. Affected file is
1779 silcd/packet_receive.c.
1781 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1782 sources correctly to distribution. Fixes --with-gmp option.
1784 * Removed the manual rehashing from ID Cache, and changed it
1785 to use the SILC Hash Table's auto rehash feature. Affected
1786 file is lib/silccore/silcidcache.c.
1788 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1790 * Fixed a bug in the silc_client_nickname_format function that
1791 handles the multiple same nickname formatting. Two clients
1792 with same nickname caused problems after the first one left
1793 and rejoined. It didn't format the nickname correctly.
1794 Affected file is lib/silcclient/idlist.c.
1796 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1798 * Don't change the topic if olod topic is same as new one.
1799 Affected file is silcd/packet_receive.c.
1801 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1803 * Added cross-reference support to the SILC Documentation
1804 generator. All types across all HTML files are now cross-
1805 referenced. Affected files util/robodoc/generator.c and
1806 scripts/silcdoc/silcdoc.
1808 * Added file lib/silcutil/silctypes.h to include all the
1809 arithmetic type definitions and some macros. Removed
1810 includes/bitmove.h and moved macros to silctypes.h.
1812 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1814 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1816 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1818 * Added `type' argument to silc_id_payload_parse_id function which
1819 now returns the type of the ID to the sent pointer. Affected
1820 file is lib/silccore/silcid.[ch].
1822 * Added check for CMODE_CHANGE notify type that mode change is
1823 allowed by the sender. Affected file silcd/packet_receive.c.
1825 * Added check for CUMODE_CHANGE notify type that mode change is
1826 allowed by the sender. Affected file silcd/packet_receive.c.
1827 Added the ID type as CUMODE_CHANGE notify type as argument
1828 to the `notify' client operation. Affected files are
1829 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1831 * Added function silc_client_add_server to the client library.
1832 Added support for resolving also channel and server info when
1833 received unknown entity in notify packet. Affected files are
1834 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1836 * Added function silc_command_get_status to return the command
1837 status from the command reply's argument payload. Affected files
1838 are lib/silccore/silccommand.[ch].
1840 * Added check for KICKED notify type that the kicking is
1841 allowed by the client. Affected file silcd/packet_receive.c.
1843 * Created function silc_get_input which can be used to get input
1844 (echo on or off) from user on command line. Affected files are
1845 lib/silcutil/silcutil.[ch].
1847 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1849 * Optimized silc_server_packet_relay_to_channel function.
1850 Added new function silc_channel_message_payload_encrypt which
1851 can be called directly if channel message payload needs to
1852 be encrypted and is already encoded (no need to call _encode
1853 function). Packet relaying is now done by router without any
1854 extra memory allocations. Affected files are
1855 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1856 silcd/packet_send.c.
1858 * Fixed the INVITE notify handling. It took wrong arguments
1859 as invite list and invite delete. Affected file is
1860 silcd/packet_receive.c.
1862 * Added check for TOPIC_SET notify type that the topic change is
1863 allowed by the client. Affected file silcd/packet_receive.c.
1865 * Added check for INVITE notify type that inviting is allowed by
1866 the client. Affected file silcd/packet_receive.c.
1868 * Changed the silc_server_client_on_channel to return the
1869 SilcChannelClientEntry as well. Moved the function
1870 silc_server_check_cmode_rights to server_util.[ch].
1871 Affected files are silcd/server_util.[ch], silcd/command.c.
1873 * Added function silc_server_check_umode_rights to check whether
1874 changing client's user mode is allowed. Added check for
1875 UMODE_CHANGE notify type that the umode change is allowed
1876 by the client. Affected files are silcd/server_util.[ch],
1877 silcd/packet_receive.c and silcd/command.c.
1879 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1881 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1882 ID length. It ignored that ID can be IPv6 based as well.
1883 Affected file lib/silccore/silcpacket.h.
1885 * Fixed the silc_id_id2str and silc_id_str2id to take the
1886 IPv6 address offset's into consideration. Affecte file is
1887 lib/silccore/silcid.c.
1889 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1891 * Fixed the internal Unix scheduler functions to check for
1892 NULL context they may receive. The affected file is
1893 lib/silcutil/unix/silcunixschedule.c.
1895 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1897 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1898 can specify different directory with --home command line
1899 parameter. Affected files irssi/src/silc/core/client_ops.c,
1902 * SILC-specific commands aren't now executed if the active server
1903 isn't of SILC-type, so there won't be problems with having
1904 IRC and SILC protocol support in same client. Affected files
1905 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1908 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1910 * Improved the signal support in SILC Schedule. Added new
1911 function silc_schedule_signal_call which is used by application
1912 to mark a signal to be called. It is now safe to perform
1913 any kind of tasks in signal callbacks since it is guaranteed
1914 that the application specified signal callback is called
1915 after the signal is over. Affected files are
1916 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1918 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1920 * Added `name' field to SilcChannelPrivateKey to represent
1921 application given name for the key. Moved also the context from
1922 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1923 Added the `name' argument also to the function
1924 silc_client_add_channel_private_key.
1926 Added function silc_client_current_channel_private_key to set the
1927 current channel private key in use.
1929 Added "change" command to KEY command which can be used to change
1930 the current channel private key. Bound the command also to
1931 alt+K (Alt+Shift+k).
1933 Also affected files lib/silcclient/client_channel.c,
1934 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1936 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1938 * Added silc_rng_get_byte_fast function in to the
1939 lib/silccrypt/silcrng.[ch].
1941 * Changed the interface of silc_packet_assemble and the
1942 silc_packet_send_prepare. If silc_packet_assmble is now
1943 called the application does not call silc_packet_send_prepare
1944 because the library will call it automatically. These
1945 interfaces now also return a reference to the outgoing buffer
1946 which includes the assembled packet, which the application can
1947 use to encrypt the packet.
1949 Affected files are lib/silccore/silcpacket.[ch],
1950 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1951 silcd/packet_send.c, server_backup.c and packet_receive.c.
1953 * Fixed a packet sending bug on very high load, where outgoing
1954 packet queue wasn't handled correctly and packets got corrupted.
1955 Affected files are lib/silcutil/*/silc*sockconn.c,
1956 lib/silcclient/client.c and silcd/server.c.
1958 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1960 * Added macro SILC_PACKET_DATALEN which can be used during
1961 packet assembling to check whether the data to be added to
1962 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1963 len is truncated until it fits it.
1965 Added checks for maximum length of channel message payload and
1966 private message payload also.
1968 Added checks for maximum packet length in server and in
1971 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1972 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1973 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1974 lib/silcclient/client_prvmsg.c.
1976 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1978 * Added silc_server_packet_queue_purge call to the
1979 silc_server_disconnect_remote to assure that all data in the
1980 queue before disconnecting is sent to the network. Affected
1981 file silcd/server.c.
1983 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1985 * Added the deleting of server's own ID cache entry to the
1986 silc_server_free function. Free also everything else that
1987 has been allocated in silc_server_init. The affected file
1990 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1992 * Added functions silc_parse_version_string, silc_version_to_num,
1993 and silc_ske_parse_version to parse SILC protocol style version
1994 strings. Affected files lib/silcutil/silcutil.[ch] and
1995 lib/silcske/silcske.[ch].
1997 * Added new configuration params: version_protocol, version_software
1998 and version_software_vendor to specify what version the remote
1999 host must at least be to be able to connect to server. The vendor
2000 string can be regex matched too. Added new function
2001 silc_server_connection_allowed to check maximum number of allowed
2002 connections, and allowed versions for incoming connections.
2003 Affected files are silcd/server.c, server_util.[ch] and
2006 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2008 * Added preliminary support for signals in scheduler. The
2009 signals we care about are now blocked always when the scheduler
2010 is locked. This way we can synchronise the use of signal with
2011 scheduler. It is guaranteed that when signal occurs the scheduler
2012 is not locked, and thus new tasks can be safely added to the
2015 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
2016 to silc_schedule_internal_init and silc_schedule_internal_uninit.
2017 Added new platform specific routines
2018 silc_schedule_internal_signals_[un]block and
2019 silc_schedule_internal_signal_[un]register.
2021 Added new functions to SILC Schedule API:
2022 silc_schedule_signal_[un]register. Each signal that application
2023 is going to use should be registered to the scheduler.
2025 Affected files are lib/silcutil/silcschedule.[ch],
2026 lib/silcutil/*/silc*schedule.c.
2028 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2030 * Check for unauthenticated client and server in the
2031 silc_server_new_client and silc_server_new_server functions.
2032 Affected file silcd/packet_receive.c.
2034 * Added function silc_string_is_ascii to check whether given
2035 string is 7-bit ASCII string. Affected files are
2036 lib/silcutil/silcutil.[ch].
2038 * Added function silc_id_is_valid_server_id into the
2039 silcd/serverid.c and added checking for valid Server ID's in
2040 silc_server_new_server. The Server ID must always be based
2041 on the server's public IP address.
2043 * Added logging of DISCONNECT packet message in the server.
2044 Affected file silcd/server.c.
2046 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2048 * Changed all library interfaces that use Global RNG to also
2049 accept SilcRng as argument. Affected files are
2050 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
2051 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
2052 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
2053 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
2054 lib/silccrypt/rsa.c.
2056 * Added function silc_pkcs_generate_key to the
2057 lib/silccrypt/silcpkcs.[ch] for applications so that they
2058 don't need to do pkcs->pkcs->init calls anymore.
2060 * Remove SilcSocketConnection from the SFTP API since it really
2061 wasn't needed there. The application has the information
2062 saved in its contexts anyway and the SFTP layer doesn't need
2063 know about it. Affected files lib/silcsft/silcsftp.h and
2064 lib/silcsftp/sftp_[server/client].c.
2066 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
2067 The SilcSimContext is not SilcSim.
2069 * Fixed possible buffer overflows in silc_id_render in the
2070 lib/silcutil/silcutil.c.
2072 * On EPOC the global crypto module lists are not used at all
2073 in the crypto library. Added support for using the constant
2074 algorithm list on EPOC. Affected files are
2075 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
2078 * Fixed the handling of third parameter of KICKED notify, since
2079 it was mistakenly updated to SILC Protocol 1.0 even though it
2080 is to be included in 1.1. Since it is not in 1.0 it is not
2081 mandatory, and this fix now handles it only if it is provided,
2082 and it is not error if it is not provided. Affected file
2083 lib/silcclient/client_notify.c.
2085 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2122 file lib/silcutil/silcutil.[ch].
2124 * Added support for specifying multiple public keys for Client
2125 connection section in server configuration file. This makes it
2126 possible to accept multiple public keys from same host, or to
2127 make a section that accepts any incoming host, and have the
2128 accepted public keys listed in the section.
2130 Added functions silc_sever_[find/get]_public_key, added the
2131 support for this actually to all connection sections but only
2132 the Client section is currently allowed to specify multiple

2239 application does not need to define them. Affected file
2240 includes/silcincludes.h.
2242 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
2243 old name went against naming convention. Applications now
2244 include "silcclient.h" instead of "clientlibincludes.h".
2245 Removed includes/clientlibincludes.h, it is redundant now.
2247 * Renamed includes/version.h to silcversion.h.
2249 * Added really preliminary support for OS/2 into the util
2250 library. Only thread & mutex API is implemented, others
2251 are still to be implemented. Created the lib/silcutil/os2/
2252 directory. Created also file includes/silcos2.h.

2285 * Added `user_count' to the SilcChannelEntry which now tells the
2286 number of users on the channel. The user count is now saved
2287 in normal server of global channels as well. Affected files
2288 silcd/server.c, idlist.h, packet_receive.c and command.c.
2290 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
2291 include file utility functions.
2293 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
2294 instead of calling directly OS routines.
2296 * Fixed NICK change printing in Irssi SILC Client. Fixed
2297 KICKED notify printing in Irssi SILC Client. Affected file
2298 irssi/src/silc/core/client_ops.c.

2306 * ROBOdoc documented the lib/silcske/silcske.h, and improved
2307 the SKE interface a bit.
2309 * Fixed padding problem in PKCS#1. The padding was not actually
2310 random since the random number generator was used incorrectly.
2311 This security bug affects only when encrypting with PKCS#1, and
2312 it is not currently used at all in SILC. SILC only use signing
2313 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
2315 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2373 is now done in silc_core_init() which also fixes autoconnecting
2376 Affected files irssi/src/silc/core/silc-core.c,
2377 irssi/src/fe-text/silc.c.
2379 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2381 * Added new configuration options and blocks:
2382 keepalive_secs, reconnect_count, reconnect_interval,
2383 reconnect_interval_max, reconnect_keep_trying and
2384 require_reverser_lookup. Added ConnectionParam block, and
2385 implemented the connection parameters when connecting as
2386 initiator and when accepting connections as responder.

2398 the connection configuration object from the SilcServerConnection
2399 object instead of finding it during the connecting phase.
2400 Added the configuration object to SilcServerConnection struct.
2401 Affected files silcd/server_internal.h, server.c.
2403 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2405 * Add the client on channel after it was resolved at the
2406 channel message receiving, and it was not already on the
2407 channel. Affected file lib/silcclient/client_channel.c.
2409 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2425 authentication to be set at the same time.
2427 Added `prefer_passphrase_auth' setting in config file which
2428 can be used to set to prefer passwd auth if both passwd and
2429 public key is set. If not set, public key is preferred.
2430 This has effect only when being initiator (responder will try
2433 Added support for authentication with passphrase and public key
2434 at the same time. The passphrase is tried first always since
2435 it is faster to check.
2437 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2439 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2485 * Fixed the file transfer's key agreement payload to include
2486 zero port also if the hostname is NULL because it could not
2489 Call file transfer monitor callback now also if error occurs
2490 during key agreement protocol.
2492 Changed the silc_client_file_send interface to return the
2493 SilcClientFileError instead of session id. The session ID
2494 is returned into pointer provided as argument.

2511 file lib/silcutil/silclog.c.
2513 * Fixed the channel message payload decryption in the function
2514 silc_channel_message_payload_decrypt to not modify the original
2515 buffer before it is verified that the message decrypted
2516 correctly. Otherwise, next time it is called with correct
2517 channel key it won't encrypt since the payload is corrupted.
2518 Affected file lib/silccore/silcchannel.c.
2520 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2532 * Fixed a bug in hash table internal routine for traversing
2533 the table with foreach callback. The current entry may
2534 become invalid in the callback but it was referenced after
2535 the callback returned.
2537 Do not allow auto rehashing of hash table during the
2538 silc_hash_table_foreach operation, for same reasons as it is
2539 not allowed for SilcHashTableList. Affected files are
2540 lib/silcutil/silchashtable.[ch].
2542 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2544 * Defined DLLAPI into silcincludes.h and silcwin32.h for

2552 lib/silcclient/client_prvmsg.c.
2554 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2556 * Added function silc_client_add_channel,
2557 silc_client_replace_channel_id, and removed functions
2558 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2559 from client library.
2561 * Added cross reference of the joined channels to the

2563 users list to SilcHashTable. The affected files are
2564 lib/silcclient/idlist.[ch].
2566 * Fixed a bug in hash table tarversing. While the hash table
2567 is traversed with SilcHashTableList the table must not be
2568 rehashed. It is now guaranteed that auto rehashable tables
2569 are not rehashed while tarversing the list. Also defined that
2570 silc_hash_table_rehash must not be called while tarversing
2571 the table. Added function silc_hash_table_list_reset that must
2572 be called after the tarversing is over. The affected files are
2573 lib/silcutil/silchashtable.[ch].
2575 * Changed all hash table traversing to call the new
2576 silc_hash_table_list_reset in server and in client library.
2578 * Added function silc_client_on_channel to return the
2579 SilcChannelUser entry if the specified client entry is joined
2580 on the specified channel. This is exported to application as
2581 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

2586 server. The notify for mode change must be sent always and
2587 not only if !cmd->pending. Affected file silcd/command.c.
2589 * Fixed the WHOWAS command's reply sending to support the
2590 lists correctly. Affected file silcd/command.c.
2592 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2594 * When sending JOIN command to router for processing the
2595 sender's old command identifier was not saved back to the
2596 sender's command context, fixed now. The affected file is
2599 * Create the key in JOIN command of the router did not return
2600 the channel key, added check for this. Affected file is
2603 * Fixed a channel ID update bug in JOIN command reply. Do
2604 not directly upgrade the ID but call the function
2605 silc_idlist_replace_channel_id if the ID was changed.
2606 Affected file silcd/command_reply.c.
2608 * Fixed memory leaks from command calling if it would fail.
2609 Affected file silcd/command.c.
2611 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2613 * Applied patches from cras:
2615 Memory leak fixes around libaries, irssi window resize fix,
2616 new silclist.h and silcdlist.h, all extern inline changed to
2619 * Removed dotconf from lib/dotconf, not needed anymore.
2621 * Removed TRQ from lib/trq, not needed anymore.
2623 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2624 with server connections. Later this will be configurable
2625 in config file after new config file is done. Affected file
2628 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2630 * Fixed a crash in server related to channel announcements.
2631 Affected file silcd/server.c.
2633 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2635 * Fixed memory leaks in silc_server_create_new_channel*
2636 functions. Affected file silcd/server.c.
2638 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2639 which ID was changed. This way the router will send the
2640 user list for the channel again, and server won't be in
2641 desync in some rare circumstances. Affected file is
2642 silcd/packet_receive.c.
2644 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2646 * Check for NULL socket pointer in the function
2647 silc_server_packet_send_to_channel_real. Affected file
2648 silcd/packet_send.c.
2650 * Fixed the BAN notify handling to correctly remove ban
2651 list. Affected file silcd/packet_receive.c.
2653 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2655 * Fixed some header addition to Toolkit distribution in
2656 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2658 * Added lib/silcclient/client_ops_example.h as an template
2659 file for application programmers to quickly start using
2660 the SilcClientOperation functions in their application.
2661 Updated the lib/silcclient/README as well to tell about this
2662 nice file made available.
2664 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2666 * Call silc_server_remove_from_channels when removing client
2667 entry when NO_SUCH_CLIENT_ID was received. Affected file
2668 is silcd/command_reply.c.
2670 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2672 * Added server & router operator statistics updating. Affected
2673 file silcd/packet_receive.c and silcd/command.c.
2675 * Fixed the SERVER_SIGNOFF notify handling on normal server
2676 not to save the history information for clients. Same was
2677 fixed earlier in remove_clients_by_server function, but not
2678 here. Affected file silcd/packet_receive.c.
2680 * Raised the default connection-retry count from 4 to 7 in
2681 server. Affected file silcd/server.h.
2683 * Cancel any possible reconnect timeouts when we start the
2684 key exchange. Affected file silcd/server.c.
2686 * Do not reconnect on connection failure when SCONNECT was
2687 given. Affected files silcd/server.[ch].
2689 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2691 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2693 * Fixed the NICK command to always give the unformatted
2694 nickname to the one giving the NICK command. If unformatted
2695 nickname is cached already it will be formatted and the
2696 local entry will always get the unformatted nickname.
2697 Affected file lib/silcclient/idlist.c.
2699 * Fixed some double frees from client library commands.
2700 Affected file is lib/silcclient/command.c.
2702 * Fixed CUMODE command in server to assure that no one can
2703 change founder's mode than the founder itself, there was a
2704 little bug. Affected file silcd/command.c.
2706 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2708 * Removed the SilcClientCommandDestructor from the client
2709 libary, it is not needed anymore. Affected files are
2710 lib/silcclient/silcapi.h, command[_reply].[ch],
2711 client_notify, idlist.c.
2713 * Fixed GETKEY command to first resolve client, and then
2714 resolve the server only if the client was not found, instead
2715 of resolving both at the same time. Affected file is
2716 lib/silcclient/command.c.
2718 * Added silc_client_start_key_exchange_cb and lookup the
2719 remote hostname and IP address before starting the key
2720 exchange with server. The affected file is
2721 lib/silcclient/client.c.
2723 * The server's public key is now saved using the IP address
2724 of the server and not the servername for the filename.
2725 The hostname public key filename is checked as an fall back
2726 method if the IP address based filename is not found.
2728 Fixed the GETKEY command to save the fetched server key
2729 in correct filename.
2731 Print the remote server's hostname now when new key is
2732 received during connection process. Affected file is
2733 irssi/src/silc/core/client_ops.c.
2735 * Return always our own public key to the client if it asks
2736 for it with GETKEY command. Affected file silcd/command.c.
2738 * Removed the use_auto_addr variable from default config
2739 file since it was in wrong section. Affected file is
2742 * Fixed TOPIC_CHANGE notification to not route it when it
2743 was sent using silc_server_send_notify_to_channel function.
2744 Affected file silcd/command.c.
2746 * Fixed silc_server_send_notify_kicked to send the kicker's
2747 Client ID also, it was missing. Affected files are
2748 silcd/command.c, silcd/packet_send.[ch].
2750 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2752 * Do not save client history information in SERVER_SIGNOFF.
2753 Fixes the bug in normal server that it does not detect
2754 the client becoming valid after the server becomes back
2755 online. Affected file silcd/server_util.c.
2757 * Added `sock_error' field into the SilcSocketConnection
2758 context. When error occurs during socket operation (read
2759 or write) the error is saved. Added also new function
2760 silc_socket_get_error to return human readable socket error
2761 message. Affected files are lib/silcutil/silcsockconn.[ch],
2762 lib/silcutil/unix/silcunixsockconn.c, and
2763 lib/silcutil/win32/silcwin32sockconn.c.
2765 * The server now prints the socket error message in the
2766 signoff for client. Affected file silcd/server.c.
2768 * Fixed the `created' channel information sending from router
2769 to server in JOIN command. Checks now whether the channel
2770 really was created or not and set it according that.
2772 Fixed the JOIN command to use the client entry's current
2773 ID during the joining procedure instead of the one it sent
2774 in the command (it is checked though), since it can change
2775 between the packet processing and command processing, and
2776 would just case unnecessary pain in the client end. Affected
2777 file silcd/command.c.
2779 * Fixed a channel key payload sending to use correct channel
2780 ID when the server was forced to change the channel's ID by
2781 router. Router sent the key payload with the old Channel ID.
2782 Affected file silcd/packet_receive.c.
2784 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2786 * Call silc_server_save_channel_key only if the key payload
2787 was provided in the JOIN command's command reply. Affected
2788 file silcd/command_reply.c.
2790 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2792 * Fixed silc_mp_sizeinbase to return the value correctly with
2793 MPI. Affected file lib/silcmath/mp_mpi.c.
2795 * Fixed the stop_server signal to correctly stop the scheduler
2796 and gracefully stop the server when SIGTERM or SIGINT signals
2797 are received. Affected file silcd/silcd.c.
2799 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2801 * Simple handling of TERM and HUP signals. Also added some log
2802 flushing call around. Affected file is
2805 * Fixed small bugs in silclog.c. Now buffering output will take
2806 effect after 10 seconds since startup: This will ensure that
2807 no important startup messages are lost. Also output redirection
2808 will preserve original format ([Date] [Type] message).
2809 Affected file is lib/silcutil/silclog.c.
2811 * Added two options to the config file, in the logging section:
2812 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2813 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2815 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2817 * Do not print the warning about log files not being initialized
2818 more than once to avoid excess logging. Affected file is
2819 lib/silcutil/silclog.c.
2821 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2822 the SIM copying in make install in Makefile.am.pre.
2824 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2826 * Rewritten silclog APIs. Globally interesting changes follows:
2827 silc_log_set_files() changed to silc_log_set_file().
2828 silc_log_set_callbacks() changed to silc_log_set_callback().
2829 ROBOdoc documented silclog header file.
2830 SilcLogCb now returns bool to wether inihibit the default
2831 handler or not (to keep the old behaviour return always TRUE).
2832 The new APIs should also fix the problem of the
2833 silcd_error.log file that was written in the current directory.
2836 Log files streams will remain opened after silc_log_set_file()
2837 call, means less CPU usage notably on high traffic servers.
2838 File streams are now full buffered, and flushed to the disk
2839 every 5 minutes, lesses HD activity and CPU usage.
2840 Messages can be redirected, allowing admins to configure
2841 one single logfile for all server messages.
2842 the silc_log_quick global variable to activate fast-logging.
2843 Affected files lib/silcutil/silclog.[ch]
2845 * Changed some code to conform new silclog APIs. Affected
2846 files are doc/example_silcd.conf.in, silcd/server.c
2847 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2850 * Fixed a memory leak that could occur in some situations.
2851 Affected file silcd/serverconfig.c.
2853 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2855 * Added the silc_client_del_client to remove the client from
2856 all channels as well. Affected file lib/silcclient/idlist.c.
2858 * Fixed the client library to correctly remove the client
2859 from all channels when the client entry is being destroyed.
2860 Affected file lib/silcclient/client_notify.c, command.c.
2862 * Added auto-nicking support to the client library. If the
2863 applicatio now sets client->nickname it will be sent to the
2864 server after connecting by the library. This way for example
2865 SILCNICK (or IRCNICK) environment variables will have effect
2866 and always change the nickname automatically to whatever
2867 it is wanted. Affected file lib/silcclient/client.[ch].
2869 * Renamed silc_server_command_bad_chars to the
2870 silc_server_name_bad_chars and moved it to the
2871 silcd/server_util.[ch]. Added also new function
2872 silc_server_name_modify_bad to return nickname that
2873 includes bad characters as new nickname without those
2874 bad characters. This check and modify is now used in
2875 silc_server_new_client when the username is initially set
2876 as nickname, so it must be checked to be valid nickname.
2877 Affected file silcd/packet_receive.c.
2879 * The nickname length is now taken from the packet for real
2880 and not trusted to strlen() since it clearly can return
2881 wrong length for nickname including bad characters. This
2882 also applies to channel names. Affected file silcd/command.c.
2884 * Removed the lib/silcsilm/modules directory. Modules are now
2885 compiled into the lib/silcsim. Fixed the copying of the
2886 modules to follow symbolic links in Makefile.am.pre.
2888 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2890 * Fixed silc_string_regexify list creation. Fixes bugs with
2891 BAN and INVITE commands in server. The affected file is
2892 lib/silcutil/unix/silcunixutil.c.
2894 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2896 * Removed the command destructor entirely from the server's
2897 command and command reply routines. It is not needed, and
2898 its usage was buggy and caused crashes. Affected files are
2899 silcd/command[_reply].[ch].
2901 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2903 * Cancel protocol and NULL sock->protocol if timeout
2904 occurred during protocol. Affected file silcd/server.c.
2906 * Cancel protocol timeouts always before calling the final
2907 callback, to assure that after final callback is called
2908 no other state will be called for the protocol anymore.
2909 Affected file silcd/protocol.c.
2911 * Print error log if incoming connection configuration could
2912 not be found. Affected file silcd/server.c.
2914 * Fixed JOIN command to correctly save the founder mode
2915 to the client on normal SILC server, when the channel
2916 was created by the router. Affected file silcd/command.c.
2918 * Fixed LIST command (hopefully) to send correct reply
2919 packets. Affected file silcd/command.c.
2921 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2923 * The silc_packet_receive_process now returns FALSE if the
2924 read data was invalid packet, and TRUE if it was ok.
2926 The server now checks that if unauthenticated connection
2927 sends data and its processing fails the server will close
2928 the connection since it could be a malicious flooder.
2930 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2932 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2934 * Make sure the warning about error opening a log file is
2935 printed only once and not everytime it fails (produces
2936 too much useless log). Affected file lib/silcutil/silclog.c.
2938 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2940 * Made the silc_server_daemonise() function more readable.
2941 Affected file silcd/server.c.
2943 * Pid file is now optional, the user may comment it out from
2944 the config file. Removed define SILC_SERVER_PID_FILE, we
2945 don't need a default any longer. Affected file
2946 configure.in.pre, lib/Makefile.am.pre.
2948 * Make some use of the pid file. The server now dies at startup
2949 if it detects a valid pid file on his path. The server would
2950 die anyway in this circumstance, because of the bind() failure.
2951 Affected file silcd/silcd.c.
2953 * No longer compiling lib/dotconf.
2955 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2957 * Fixed JOIN command parsing not to crash. Affected file
2958 lib/silcclient/command.c.
2960 * Fied the NICK_CHANGE notify to add the new client entry
2961 even it is resolved. This removes an <[unknown]> nick
2962 thingy bug in the client. Affected file is
2963 lib/silcclient/client_notify.c.
2965 * Do not try to allocate 0 bytes (efence does not like it)
2966 in lib/silccore/silccomand.c when encoding payload.
2968 * Do not take IRCNICK as nickname in Irssi SILC client since
2969 it is not possible to set nickname before hand connecting
2970 the server (TODO has an entry about adding auto-nicking
2973 * Changed the silc_server_command_pending to check whether
2974 there already exists an pending entry with the specified
2975 command, command identifier and pending callback. This is
2976 to fix IDENTIFY and WHOIS related crashes that may register
2977 multiple pending commands with same identifier. Affected
2978 file silcd/command.c.
2980 * Fixed the server to reconnect to the router even if it
2981 was already reconnecting and EOF was received. This to
2982 fix a possibility that the server wouldn't ever try to
2983 auto-reconnect to the router. Affected file silcd/server.c.
2985 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2987 * Fixed the server's password authentication to use the
2988 length of the locally saved password, and not the one
2989 sent in the packet. Affected file silcd/protocol.c.
2991 * Fixed same password authentication problem in the
2992 Authentication Payload handling routines in
2993 lib/silccore/silcauth.c.
2995 * Yet another password authentication problem fixed with
2996 channel password handling in silcd/command.c.
2998 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3000 * If first character of string in silc_parse_userfqdn is '@'
3001 then do not parse it. Affected file is
3002 lib/silcutil/silcutil.c.
3004 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3006 * Fixed minor bug in IDENTIFY command reply sending, which
3007 caused various weird problems during JOIN when it was
3008 resolving names for users. Affected file silcd/command.c.
3010 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3012 * Fixed the IDENTIFY command reply sending to chech better valid
3013 clients. It was possible to send incomplete list of replies.
3014 Affected file silcd/command.c.
3016 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3018 * Added silc_client_command[s]_[un]register functions now to
3019 dynamically register the commands in client library. Removed
3020 the static table of commands. This allows the client library
3021 to call commands without causing the application to know about
3022 what commands library has called.
3024 Removed the INFO command reply kludge to detect when the command
3025 was called by library. Now library use its own command reply
3026 function for INFO command.
3028 Added function silc_client_command_call to call a command.
3029 Application can use it to call command, not access the structure
3032 Now all commands that are sent by the client library (not
3033 explicitly sent by application) use own command reply functions.
3035 Affected files around lib/silcclient/ and in
3036 irssi/src/silc/core/.
3038 * Fixed the WHOIS command reply sending to chech better valid
3039 clients. It was possible to send incomplete list of replies.
3041 Fixed the WHOIS and IDENTIFY to send the request to router
3042 if normal server did not do it and did not find any results.
3044 Affected file silcd/command.c.
3046 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3048 * Moved the internal data from SilcClient context into its
3049 own file, not accesible to application. Affected files
3050 lib/silcclient/client.h and lib/silcclient/client_internal.h,
3051 and other files in client library.
3053 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3055 * Added doc/examples installation target in Makefile.am.pre.
3058 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3060 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
3061 commands the found client entry will be removed from the
3062 cache, after notifying application about the error. Affected
3063 file lib/silcclient/command_reply.c.
3065 * Changed the /MSG to check for exact nickname user gave, and
3066 not let `nick' match `nick@host' if it is only one found. Now,
3067 user must type the exact nickname (like nick@host2) even if
3068 there are no more than one same nicks found. This is to avoid
3069 a possibility of sending nickname to wrong nickname since
3070 `nick' could match `nick@host'. Affected file is
3071 irssi/src/core/silc-servers.c.
3073 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3075 * Do not print "you are now server operator" or similar when
3076 giving /away command. Affected files are
3077 irssi/src/silc/core/client_ops.c, silc-servers.h.
3079 * Made the silc_server_command_pending_error_check to send
3080 the same command reply payload it received back to the
3081 original sender of the command. This way all arguments
3082 that was received by the server will be received by the
3083 client too. Affected file silcd/command.c.
3085 * Added the silc_idcache_add to return the created cache entry
3086 to a pointer. Affected file lib/silccore/silcidcache.[ch].
3088 * Add global clients to expire if they are not on any channel.
3089 This is because normal server will never know if they signoff
3090 if they are not on any channel. The cache expiry will take
3091 case of these entries. This is done by normal servers only.
3092 The affected files are silcd/command_reply.c,
3093 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
3095 * If server receives invalid ID notification for WHOIS or
3096 IDENTIFY and the ID exists in the lists, it is removed.
3097 Affected file silcd/command_reply.c.
3099 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
3100 in client then client entry that it matches is searched and
3101 the nickname is printed on the screen for user. Affected
3102 file irssi/src/silc/core/client_ops.c.
3104 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3106 * Use cache entry expire time in the LIST command reply to
3107 purge old entries from the cache after the LIST command
3108 reply has been received. This way we don't have non-existent
3109 entries in the cache for too long. Affected file is
3110 silcd/command_reply.c.
3112 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3114 * If we are normal server, and we've not resolved client info
3115 in WHOIS or IDENTIFY from router, and it is global client,
3116 we'll check whether it is on some channel. If it is not
3117 then we cannot be sure about its validity and will resolve it
3118 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
3119 file silcd/command.c.
3121 * Search channel by name (if possible) rather than by ID
3122 in IDENTIFY command's command reply. Affected file is
3123 silcd/command_reply.c.

3129 silcd/packet_send.c and silcd/packet_receive.c.
3131 * Implemented the <founder auth> payload handling in the JOIN
3132 command. If provided all conditions for channel joining
3133 except requirement to provide correct passphrase can be
3134 overrided by the channel founder. Updated the protocol specs.
3135 Affected file silcd/command.c.
3137 Added support for founder auth in JOIN command in client
3138 library. Fixed the parsing of the JOIN command now to support
3139 all options as they should be. The affected file is
3140 lib/silcclient/command.c.
3142 * Optimized the WHOIS and IDENTIFY commands to send the request
3143 to router only if it includes nicknames or other names. If
3144 they include only IDs then check the local cache first before
3145 routing. Affected file is silcd/command.c.
3147 * Added channels topic announcements. Affected file is
3148 silcd/packet_receive.c and silcd/server.c.
3150 * Fixed the silc_server_send_notify_topic_set to really destine
3151 the packet to channel. Affected file silcd/packet_send.c.
3153 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
3154 library. Affected file lib/silcclient/client_notify.c.

3168 lib/silccore/silcidcache.c
3173 * ROBOdoc documented the lib/silcske/groups.h file and a
3174 bit changed the interface for better.
3176 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3178 * Update the client entry context in the ID cache after
3179 nick change. Affected file lib/silcclient/command.c.
3180 Fixes the CUMODE command when regaining founder privileges,
3181 and a little WHOIS problem.
3183 * Fixed silc_net_gethostbyname to correctly call the
3184 inet_ntop. Affected file lib/silcutil/silcnet.c.
3186 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3188 * Added IPv6 support checking to the configure.in.pre, added
3189 also --enable-ipv6 option to override the check. Affected
3190 file configure.in.pre.
3192 * The silc_thread_create now calls the start function
3193 directly if threads support is not compiled in. Removes
3194 ugly #ifdef's from generic code. Affected files are
3195 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
3197 * Added silc_net_gethostby[name/addr]_async to asynchronously
3198 resolve. Affected files are lib/silcutil/silcnet.[ch].

3204 file is silcd/serverid.c.
3206 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3208 * Added silc_net_gethostby[addr/name] into the
3209 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
3210 routines. Added silc_net_is_ip[4/6]. Affected file is
3211 lib/silcutil/unix/silcunixnet.c. All routines that take
3212 address as argument now supports both IPv4 and IPv6 addresses.
3214 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3216 * Fixed LIST command reply sending in server. Affected file
3219 * Server now sends the kicker's client ID in the KICK notify
3220 to the kicked client. Affected file silcd/command.c.
3222 * The client library now parses the kickers client ID and
3223 UI displays it. Affected files lib/silcclient/client_notify.c
3224 and irssi/src/silc/core/silc-channels.c, module-formats.c.
3226 * Made all payload parsing function prototypes consistent.
3227 They all take now const unsigned char * and uint32 pair as
3228 the payload data instead of SilcBuffer. Changes all around
3229 the source tree. Other unsigned char* -> const unsigned char*
3230 changes around the tree as well.
3232 * Optimized SFTP client and server packet sending not to
3233 allocate new buffer for each packet but to recycle the
3234 first allocated buffer. Affected files are
3235 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
3237 * Optimized the SFTP client to use SilcList instead of
3238 SilcDList for requests, because it is faster. Affected file
3239 is lib/silcsftp/sftp_client.c.
3241 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
3242 into lib/silccore/silcid.[ch].
3244 Renamed silcpayload.[ch] into silcargument.[ch].
3246 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3248 * If client entry is deleted with active key agreement
3249 session, abort the session.
3251 The silc_client_abort_key_agreement now calls the completion
3252 callback with new SILC_KEY_AGREEMENT_ABORTED status.
3254 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
3257 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3259 * Don't use __restrict in older GCC's. Affected file is
3260 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
3262 * silc_net_localhost now attempts to reverse lookup the
3263 IP/hostname. Affected file lib/silcutil/silcnet.c.
3265 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
3266 command. It can be used to gain founder privileges at
3267 the same time when joining the channel.
3269 Defined that the SILC_NOTIFY_TYPE_KICKED send the
3270 kicker's client ID as well. Updated protocol specs.
3272 Defined that the server must send SILC_COMMAND_IDENTIFY
3273 command reply with error status to client who sent
3274 private message with invalid client ID.
3276 Updated the protocol specification.
3278 * Added silc_server_send_command_reply to send any
3279 command reply. Affected file silcd/packet_send.[ch].
3281 * Added silc_id_payload_encode_data to encode ID payload
3282 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
3284 * The server now send IDENTIFY command reply with error
3285 status if client ID in private message is invalid. Affected
3286 file silcd/packet_receive.c.
3288 * Save the server key file with server's IP address in
3289 the filename instead of hostname. The affected file is
3290 irssi/src/silc/core/client_ops.c.
3292 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3294 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
3297 * Added libtool support for compiling shared objects in
3298 lib/silcsim. Affected file configure.in.pre and
3299 lib/silcsim/Makefile.am. Original patch by cras.
3301 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3303 * Pid file configuration, and server's config file fixes
3304 patch by toma. Updated CREDITS file.
3306 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3308 * Fixed silc_client_channel_message to not try to decrypt
3309 the message twice if it resolved the destination client
3310 information. This could cause of dropping one channel
3311 message. Affected file lib/silcclient/client_channel.c.
3313 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3315 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3316 lib/silcclient/client.c. This function is used when the SILC
3317 Client is run under some other scheduler, or event loop or
3318 main loop. On GUI applications, for example this may be
3319 desired to used to run the client under the GUI application's
3320 main loop. Typically the GUI application would register an
3321 idle task that calls this function multiple times in a second
3322 to quickly process the SILC specific data.
3324 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3326 * Fixed silc_server_drop() for dropping the supplementary
3327 groups as well, this could cause a security hole on some
3330 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3332 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
3335 * Write PID file after dropping privileges. Added -F option
3336 to run server on foreground. A patch by debolaz.
3337 Affected files silcd/server.c, silcd/silcd.c.
3339 * Fixed MOTD to return the MOTD file server name. Affected
3340 file silcd/command.c.
3342 * Added INFO command reply handling to the Irssi SILC Client.
3343 Affected file irssi/src/silc/core/client_ops.c.
3345 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3347 * Fixed the silc_idcache_list_* routines to really support
3348 the dynamic list. Fixes a crash. Affected file is
3349 lib/silccore/silcidcache.c.
3351 * Fixed the LIST command reply to really call LIST command's
3352 pending callbacks. Affected file silcd/command_reply.c.
3354 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3356 * Update conn->local_entry->nickname after giving NICK
3357 command. Affected file lib/silcclient/command.c.
3359 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3361 * Added the [pid] option to the silcd configuration file
3363 Affected files: serverconfig.[ch] and silcd.c
3365 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3367 * Save fingerprint in WHOIS command reply in server.
3368 Affected file silcd/command_reply.c.
3370 * Fixed NICK commands pending callback registration.
3371 Affected file lib/silcclient/command.c.
3373 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3375 * Use ++server->cmd_ident when sending commands in server,
3376 instead of random number. Affected file silcd/command.c.
3378 * Fixed GETKEY command reply to call actually GETKEY pending
3379 command callbacks. Affected file silcd/command_reply.c.
3381 * A bit stricter check for nicknames. Check for same nickname
3382 in NICK command also. Affected file silcd/command.c.
3384 * Do not call INFO command everytime client ID changes, only
3385 during first connecting. Affected file lib/silcclient/client.c.
3387 * Set the new nickname only after successful command reply for
3388 NICK command is returned by server. Affected file
3389 lib/silcclient/command.c.
3391 * Remove nicknames from nicklist during server_signoff notify.
3392 Should fix /NAMES bit more. The affected file is
3393 irssi/src/silc/core/silc-channels.c.
3395 * Added `fingerprint' field to the SilcIDListData in the
3396 silcd/idlist.h to hold the fingerprint of the client's
3399 Send the fingerprint of the client's public key in WHOIS
3402 Affected files silcd/command.c, and silcd/idlist.[ch].
3404 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3405 create fingerprint from given data.
3407 * Show the fingerprint of the client's public key in WHOIS.
3408 Affected files irssi/src/module-formats.[ch] and
3409 irssi/src/silc/core/client_ops.c.
3411 * Format the multiple same nicknames also during JOIN and
3412 NICK_CHANGE notifys. Affected file is
3413 lib/silcclient/client_notify.c.
3415 * Do not print error on screen for invalid private message
3416 payload since it can come if someone is sending private
3417 messages with wrong key. Affected file
3418 lib/silccore/silcprivate.c.
3420 * Fixed multiple concurrent /PING crash. Affected file
3421 lib/silcclient/command.c.
3423 * Changed the wrong ID encoding. All IP addresses must be
3424 in MSB first order in encoded format. They were encoded
3425 wrong and was in LSB format. Affected files are
3426 silcd/serverid.c, lib/silcutil/silcutil.c.
3428 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3430 * Call the `connect' client operation through the scheduler
3431 in case of error. Affected file lib/silcclient/client.c.
3433 * Call the `failure' client operation even if the error
3434 occurred locally during a protocol. Affected file is
3435 lib/silcclient/protocol.c.
3437 * Added support of sending LIST command to router from normal
3438 server. This way normal server can get list of all channels
3439 in the network too. Fixed the channel list sending in the
3440 server too. Affected files are silcd/command.c, and
3441 silcd/command_reply.[ch].
3443 * Added silc_server_update_channels_by_server and
3444 silc_server_remove_channels_by_server. They are used during
3445 disconnection of primary router and in backup router protocol.
3446 Affected file silcd/server_util.[ch], silcd/server.c and
3447 silcd/server_backup.c.
3449 * Fixed channel adding to global list in IDENTIFY command
3450 reply in server. Affected file silcd/command_reply.c.
3452 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3454 * If the incoming packet type is REKEY or REKEY_DONE process
3455 that packet always synchronously. Fixes yet another MAC
3456 failed error on slow (dialup) connections. Affected file
3457 lib/silcclient/client.c and silcd/server.c.
3459 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3461 * Call check_version SKE callback for initiator too. Affected
3462 file lib/silcske/silcske.c.
3464 * Implemented fix for security hole found in the SKE that was
3465 fixed in the specification few days back; the initiator's
3466 public key is now added to the HASH value computation.
3467 Added backwards support for the old way of doing it too, for
3468 old clients and old servers. Affected file is
3469 lib/silcske/silcske.c.
3471 * Enabled mutual authentication by default in SKE. If initiator
3472 is not providing mutual authentication the responder will
3473 force it. This will provide the proof of posession of the
3474 private key for responder. The affected files are
3475 lib/silcclient/protocol.c and silcd/protocol.c.
3477 * Do not cache anymore the server's public key during SKE.
3478 We do mutual authentication so the proof of posession of
3479 private key is done, and if the server is authenticated in
3480 conn auth protocol with public key we must have the public
3481 key already. Affected file silcd/protocol.c.
3483 * Added new global debug variable: silc_debug_hexdump. If
3484 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3485 file lib/silcutil/silclog.[ch].
3487 * Fixed compilation warning due to char * -> const char *.
3488 Affected files lib/silcutil/silcnet.h, and
3489 lib/silccore/silcauth.[ch].
3491 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3493 * Fixed CMODE command when new channel key was created. If
3494 the creation failed the old key was removed. Next time giving
3495 same command would crash the server since the old key was
3496 freed already. Affected file silcd/command.c.
3498 * Fixed the silc_server_announce_get_channels to not crash
3499 on reconnect. Affected file silcd/server.c.
3501 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3503 * Added silc_log_set_debug_string function to set a regex
3504 string to match for debug output. Only the function names,
3505 or filenames matching the given debug string is actually
3506 printed. This way it is possible to filter out those debug
3507 strings that user is not interested in.
3509 Fixed a bug in silc_string_regexify.
3511 Affected files lib/silcutil/silclog.[ch], and
3512 lib/silcutil/unix/silcunixutil.c.
3514 * Changed the -d options in both server and Irssi SILC client
3515 to take the debug string as argument. Affected files
3516 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3518 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3520 * Added silc_hash_babbleprint to create a Bubble Babble
3521 Encoded fingerprint. The encoding is developed by Antti
3522 Huima (draft-huima-babble-01.txt), and it creates human
3523 readable strings out of binary data. Affected file
3524 lib/silccrypt/silchash.[ch].
3526 * Print the babble print now in addition of fingerprint as well
3527 in Irssi SILC client. Affected files are
3528 irssi/src/fe-common/silc/module-formats.[ch],
3529 irssi/src/fe-common/silc/core/client_ops.c.
3531 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3533 * Fixed a security problem found in SKE. The initiator's
3534 public key too is now added to the HASH hash value creation
3535 which is signed by the responder to create the SIGN value.
3536 This will prevent anyone in the middle to lie to the responder
3537 about the initiator's public key. If this is done now, the
3538 man in the middle will get caught. Updated the protocol
3541 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3543 * Better installation directory handling. Configure module
3544 paths and other paths automatically to example_silc* files
3545 in doc/. A patch by toma.
3547 * Fixed compiler warning from MPI library, and from SILC RNG.
3550 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3551 It can be configured with ./configure. A patch by toma.
3553 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3555 * Find correct make to use in prepare-clean. A patch by
3556 toma. Affected file prepare-clean.
3558 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3560 * Added irssi variables use_auto_addr, auto_bind_ip,
3561 auto_bind_port and auto_public_ip.
3563 * Changed the interface for silc_client_send_key_agreement
3564 in lib/silcclient/silcapi.h
3568 irssi/src/silc/core/silc-core.c
3570 lib/silcclient/silcapi.h
3571 irssi/src/silc/core/silc-channels.c
3572 lib/silcclient/client_keyagr.c
3575 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3577 * Added silc_pkcs_public_key_compare to compare two
3578 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3580 * Check that the client who set the founder mode on the
3581 channel is the same client that is giving the founder
3582 mode to itself. It is done by comparing the saved public
3583 key (it is saved even in the authentication is passphrase).
3584 Affected file silcd/command.c.
3586 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3588 * Do not process packet for disconnected socket connection.
3589 Affected file lib/silccore/silcpacket.c.
3591 * Process the DISCONNECT packet through scheduler in the
3592 client library. Affected file lib/silcclient/client.c.
3594 * Fixed the silc_client_packet_parse to not to increase
3595 the packet sequence number if the conn->sock and the
3596 current socket connection is not same. This can happen
3597 for example during key agreement when the conn includes
3598 multiple socket connections (listeners). Affected file
3599 lib/silcclient/client.c.
3601 * The sender of the file transfer request now provides also
3602 the pointer (listener) for the key exchange protocol. If
3603 the listener cannot be created then it sends empty key
3604 agreement and lets the receiver provide the listener.
3606 Added `local_ip' and `local_port' arguments to the
3607 silc_client_file_send. If they are provided they are used,
3608 if not then it will attempt to find local IP address, if
3609 not found or bind fails then the remote client will provide
3612 Affected files are lib/silcclient/client_ftp.c and
3613 lib/silcclient/silcapi.h.
3615 * Extended the FILE SEND command to support defining the
3616 local IP and port for key exchange listener. They are
3617 optional. Affected file irssi/src/silc/core/silc-servers.c.
3619 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3621 * Defined to WHOIS command reply the sending of fingerprint
3622 of the client's public key (if the proof of posession of the
3623 corresponding private key is verified by the server).
3624 Updated to the protocol specification.
3626 * Added support of receiving the client's public key's
3627 fingerprint in command reply in client library. Affected
3628 file is lib/silcclient/command_reply.c, and
3629 lib/silcclient/idlist.[ch].
3631 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3633 * Do not send over 128 chars long nickname to the server
3634 in NICK command. Affected file lib/silcclient/command.c.
3636 * Do not send over 256 chars long channel names to the server
3637 in JOIN command. Affected file lib/silcclient/command.c.
3639 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3641 * Assure that silc_server_close_connection cannot be called
3642 twice for same socket context. Affected file is
3645 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3647 * Send error message to application if opening file for
3648 writing during file transfer fails. Affected file is
3649 lib/silcclient/client_ftp.c.
3651 Remove all file transfer sessions for a client that we're
3652 removing from ID cache.
3654 Affected file is lib/silcclient/client_ftp.c.
3656 * Fixed silc_net_addr2bin to return correct address. Affected
3657 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3659 * Fixed file transfer session removing on signoff notify.
3660 Affected file irssi/src/silc/core/silc-servers.c.
3662 * Added the SilcClientFileError to be returned in the monitor
3663 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.

3684 client library. Affected file lib/silcclient/client_prvmsg.c.
3686 * Do not actually remove the client directly from ID cache
3687 during SERVER_SIGNOFF, but invalidate it. This way we
3688 preserve the WHOWAS info for the client. Affected file
3689 silcd/server_util.c.
3691 * Fixed SERVER_SIGNOFF notify handling in the server. The
3692 server is now able to process incoming SERVER_SIGNOFF notify
3693 for a server that it doesn't even know about. It will remove
3694 the clients provided in the notify. Affected file
3695 silcd/packet_receive.c.
3697 * Check for partial packet in data queue after every packet that
3698 was found from the queue. Return and wait for more data if
3699 there is partial data in queue. Affected file is
3700 lib/silccore/silcpacket.c.
3702 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

3717 irssi/src/fe-common/silc/module-formats.[ch].
3719 * Wrote a help file for FILE command.
3721 * Added silc_rng_global_get_byte_fast to get not-so-secure
3722 random data as fast as possible. Random data is read from
3723 /dev/urandom if available and from the SILC RNG if not
3724 available. It is used in padding generation. Affected file
3725 lib/silccrypt/silcrng.[ch].
3727 * All packets in client library are now processed synchronously.
3728 Optimized packet processing a lot. Affected file
3729 lib/silcclient/client.c.
3731 * All server connection packets are processing synchronously
3732 now in server, to optimize packet processing. Affected file
3735 * Include files are installed now only in Toolkit distribution
3736 if make install is given. Affected files: all Makefile.am's.
3738 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3740 * Assure that silc_client_notify_by_server_resolve does not
3741 resolve the client information multiple times. If it cannot
3742 be found by the first it cannot be found at all. Affected
3743 file lib/silcclient/client_notify.c.
3745 * Fixed WHOWAS command reply calling. Affected file
3746 lib/silcclient/command_reply.c.
3748 * Removed all references to silc_idlist_get_client from the
3749 Irssi SILC client since that call is internal call used by
3750 the library. The Irssi SILC client will use now client
3751 retrieval functions found in silcapi.h.
3753 * Fixed a bug in resolving nickname info before sending
3754 private message. It used freed memory. Affected file
3755 irssi/src/silc/core/silc-servers.c.
3757 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3759 * Assure my_channels statistics cannot go negative in server.
3760 Affected files silcd/server.c, silcd/server_util.c.

3776 * Added silc_net_localip to return local host's IP address.
3777 Affected file lib/silcutil/silcnet.[ch].
3779 * If key exchange or rekey protocol is active for a connection
3780 parse all packets syncronously since there might be packets
3781 in packet queue that we are not able to process without first
3782 processing packets before them. Affected file silcd/server,
3783 lib/silcclient/client.c.
3785 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3786 whether library should continue processing the packet.
3787 Affected file lib/silccore/silcpacket.h.

3833 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3834 is incomplete and is being resolved, it won't be resolved
3837 Make sure also that USERS command reply does not resolve
3838 twice information. Affected file is
3839 lib/silcclient/command_reply.c.
3841 Make sure that silc_client_get_clients_by_list does not
3842 resolve twice same information.
3844 * Check for valid client->id in the silc_server_free_client_data.
3845 Affected file silcd/server.c.
3847 * Fixed /GETKEY nick@server not to crash if the server entry
3848 is not found. Affected file lib/silcclient/command.c.
3850 * Fixed the silc_server_check_cmode_rights to check the
3851 requested modes correctly. Affected file silcd/command.c.

3858 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3860 * Call the silc_server_udpate_servers_by_server in the
3861 primary router that comes back online in the backup resuming
3862 protocol. Otherwise it routes packets wrong. Affected file
3863 silcd/server_util.[ch], silcd/server_backup.c.
3865 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3867 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3868 lib/silcutil/silcbuffmt.[ch].
3870 * Redefined the SILC packet header to include the padding
3871 length. Affected file lib/silccore/silcpacket.[ch].
3873 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3874 length for maximum padding up to 128 bytes). Affected
3875 file lib/silccore/silcpacket.h.
3877 * Removed all backwards support for old 0.5.x MAC thingies.
3878 The SILC packet header change makes it impossible to be
3879 backwards compatible.
3881 * Send the ENDING packet with timeout in the backup resuming
3882 protocol. This is to assure that all routers has connected
3883 to the primary router. Affected file silcd/server_backup.c.
3885 * Changed the RNG to take the first IV from random data. It
3886 used to take it from zero actually. Changed the RNG also
3887 to use /dev/urandom during session. /dev/random is used
3888 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3890 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3892 * Changed the SILC packet header to have the first two bytes
3893 (the packet length) encrypted. Affected files aroung the
3894 code tree, lib/silccore/silcpacket.[ch]. Removed the
3895 SilcPacketCheckDecrypt callback. It is not needed anymore
3896 since the silc_packet_receive_process will determine now
3897 whether the packet is normal or special.
3899 * Implemented the unidirectional MAC keys. Affected files
3900 lib/silcske/silcske.c, silcd/protocol.c and
3901 lib/silcclient/protocol.c.
3903 * Implemented the packet sequence number to the MAC computation.
3904 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3905 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3906 lib/silcclient/protocol.c.
3908 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3910 * Allow backup router to announce servers. All servers
3911 announced by backup router are added to the global list
3912 automatically. Update hte server's socket to our primary
3913 router also when backup router announces a server.
3914 Affected file silcd/packet_receive.c.
3916 * Do not update the client->router in the function
3917 silc_server_udpate_clients_by_server if the client is on
3918 global list. We might fail to find any specific server
3919 for locally connected clients and local cell clients. They
3920 should still use the `from' and not `to' as client->router.
3921 This fixes backup router resuming protocol. Affected file
3922 silcd/server_util.c.
3924 * Decrease channel statistics count only if the channel
3925 deletion worked. Affected files are silcd/server.c and
3926 silcd/server_util.c.
3928 * Added silc_server_update_servers_by_server to update origin
3929 of all server entries. Used during backup router protocol.
3930 Affected files silcd/server_util.[ch], silcd/server.c. and
3931 silcd/backup_router.c.
3933 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3934 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3935 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3936 lib/silccrypt/silchmac.c.
3938 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3940 * Assure that router cannot reroute the same channel message
3941 to the sender. Affected file silcd/packet_receive.c.
3943 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3945 * Made better checks that the channel message is not sent
3946 to the router it came from. Affected file is
3947 silcd/packet_send.c. Fixed memory leak too.
3949 * Announce informations for incoming router connection, but
3950 only after checking if it is replaced by backup router.
3951 Affected file silcd/packet_receive.c.
3953 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3955 * Fixed the backup resuming protocol to work in multiple
3956 router environment. Affected file silcd/server_backup.c.
3958 * Route packet only to one router in the function
3959 silc_server_packet_send_to_channel. Affected file is
3960 silcd/packet_send.c.
3962 * Fixed silc_server_send_notify_dest to set the broadcast
3963 flag. Fixed the silc_server_send_notify_topic to actually
3964 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3965 Affected file silcd/packet_send.c.
3967 * Changed the SFTP Filesystem interface. Changed the
3968 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3969 the filesystem operation function. The SilcSFTPFilesystem
3970 is now a context that is allocated by all filesystem allocation
3971 functions and it already includes the operations structure
3972 and filesystem specific context. It is given as argument
3973 now to the silc_sftp_server_start. This made the interface
3974 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3975 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3977 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3979 * Changed the backup router adding and getting interfaces
3980 in the server. The router that will be replaced by the
3981 specified backup router is now sent as argument. Affected
3982 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3985 * Added silc_net_addr2bin_ne to return the binary form of
3986 the IP address in network byte order. Affected files
3987 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3989 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3991 * Check for existing server ID in silc_server_new_server
3992 and in silc_server_connect_to_router_final and remove the
3993 old entry if it exists. Affected file silcd/packet_receive.c,
3996 * Send the channel message always to only one router, either
3997 in upstream or downstream. Affected file is
3998 silcd/packet_send.c.
4000 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4002 * Wrote the definition of the backup resuming protocol to the
4003 protocol specification.
4005 * Removed one redundant channel key generation from normal
4006 server during joining procedure. Removed one redundant
4007 channel key sending from server to router during joining
4008 procedure. Affected file silcd/command.c.
4010 * Made minor bugfixes to the backup router resuming protocol.
4011 Affected file silcd/server_backup.c, server.c.
4013 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4015 * Added --disable-asm configuration option. Affected files
4016 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
4019 * Implemented the backup resuming protocol that is used to
4020 resume the primary router position in the cell after the
4021 primary router comes back online. Affected files
4022 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
4023 and silcd/server_util.[ch].
4025 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4027 * Sleep two (2) seconds after sending QUIT command to server.
4028 Affected file lib/silcclient/command.c.
4030 * Assure that if outgoing data buffer is pending do not force
4031 send any data. Affected file silcd/packet_send.c.
4033 * Assure that if outgoing data buffer is pending do not force
4034 send any data. Affected file lib/silcclient/client.c.
4036 * Implemented the backup router support when the primary router
4037 goes down. The servers and routers can now use the backup
4038 router as new primary router without loosing connectivity.
4040 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4042 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
4043 in the server to indicate disabled entry. All data read
4044 from the connection will be ignored and no data is sent
4045 for entry that is disabled. Affected files are
4046 silcd/idlist.h, silcd/server.c.
4048 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4050 * Created SFTP client and server test programs in the
4051 lib/silcsftp/tests directory.
4053 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4055 * Implemented memory filesystem (virtual filesystem) for
4056 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
4059 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4061 * Implemented the SFTP (SSH File Transfer Protocol) to the
4062 lib/silcsftp. It includes SFTP client and SFTP server
4065 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4067 * Moved lib/silccore/silcprotocol.[ch] to the
4068 lib/silcutil library.
4070 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
4071 take variable argument list pointer as argument. Affected
4072 file lib/silcutil/silcbuffmt.[ch].
4074 * Added silc_buffer_set function that is used to set data
4075 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
4076 Affected file lib/silcutil/silcbuffer.h.
4078 * Changed various routines in the core library to use the new
4079 silc_buffer_set instead of allocating new buffer only for
4082 * Added 64-bit value formatting and unformatting support to the
4083 silc_buffer_[un]format routines. Affected file is
4084 lib/silcutil/silcbuffmt.[ch].
4086 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
4087 to includes/bitmove.h.
4089 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4091 * Fixed channel user mode saving in client library. Affected
4092 file lib/silcclient/command[_reply].c.
4094 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4096 * Defined the file transfer to the SILC Protocol. Added
4097 new packet type SILC_PACKET_FTP and defined File Transfer
4098 Payload. The mandatory file transfer protocol is SFTP
4099 (SSH File Transfer Protocol). Affected file in addition
4100 of the internet draft is lib/silccore/silcpacket.h.
4102 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
4103 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
4104 is used as part of backup router protocol when the primary
4105 router of the cell is back online and wishes to resume
4106 the position as primary router.
4108 * Redefined the MAC generation keys in the protocol. The
4109 same key is not used anymore in both direction. Both
4110 direction will now use different keys for sending and
4111 receiving. This fixes a potential security flaw. This
4112 change causes incompatibilities in the protocol.
4114 * Redefined also the MAC computation from the packet.
4115 An packet sequence number is now added to the MAC
4116 computation. This prevents possible replay attacks against
4117 the protocol. This change too causes incompatibilities
4120 Added `sequence' field to the SilcPacketContext to hold
4121 the current sequence number for the packet.
4123 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4125 * Added `created' field to the SilcIDListData in the file
4126 silcd/idlist.h to indicate the time when the entry was
4129 * Added `created' field to the SilcChannelEntry too. Affected
4130 file silcd/idlist.h.
4132 * Added `creation_time' aguments to all the announcement functions
4133 in the server. If it is provided then only the entries that
4134 was created after the provided time frame are actually
4135 announced. Affected file silcd/server.[ch].
4137 * The protocol says that the Channel ID's IP address must be
4138 based on the router's IP address. Added check for this in
4139 the silc_server_new_channel when processing incoming New Channel
4140 Payload. Affected file silcd/packet_receive.c.
4142 * Print out the correct version with --version in SILC client.
4143 Affected file irssi/src/silc/core/silc-core.c.
4145 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4147 * Fixed WHOWAS command to check for completnes of the client
4148 entry always, not just when the command is coming from client.
4149 Affected file silcd/command.c.
4151 * Added new function silc_server_packet_queue_purge to purge the
4152 outgoing data queue to the network. After the function returns
4153 it is guaranteed that the outgoing packet queue is empty.
4154 Affected file silcd/packet_send.[ch].
4156 * Purge the outgoing packet queue in the rekey protocol's final
4157 callback to assure that all rekey packets go to the network
4158 before quitting the protocol. Affected file silcd/server.c.
4160 * Added silc_client_packet_queue_parse as similar function as
4161 in server to the client library. The affected file is
4162 lib/silcclient/client.c.
4164 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4166 * Splitted silcd/server.c and created silcd/server_util.[ch]
4167 for utility functions.
4169 * Added new socket flag SILC_SF_DISABLED to indicate that the
4170 connection is open but nothing can be sent to or received from
4171 the connection. Affected file lib/silcutil/silsockconn.[ch].
4172 The checking for disabled socket is checked in the low level
4173 silc_socket_write and silc_socket_read functions.
4175 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4177 * Allow only nicknames and channel names that fits into the
4178 7-bit unsigned char ASCII set. Affected file silcd/command.c.
4180 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4182 * When processing JOIN command reply in server check that if
4183 the channel exists in our global list we'll move it the local
4184 list. Affected file silcd/command_reply.c.
4186 * Fixed the check whether client is joined on the channel already
4187 in JOIN command. Affected file lib/silcclient/command.c.
4189 * Fixed the JOIN command reply to check whether the channel
4190 already exists. Affected file lib/silcclient/command_reply.c.
4192 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4194 * Added silc_ske_status_string to map the SKE error numbers
4195 to readable strings. The affected files are
4196 lib/silcske/silcske[_status].[ch].
4198 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4200 * Do not show the private channels on the WHOIS channel list
4201 as it is not allowed by the protocol. The affected file is
4204 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4206 * Assure that the packet length digged from the actual packet
4207 is something sensible in the silc_packet_decrypt_rest_special
4208 in lib/silccrypt/silcpacket.c.
4210 * Free and NULL the allocated pointer in silc_hmac_alloc if
4211 the HMAC allocation fails. The affected file is
4212 lib/silccrypt/silchmac.c.
4214 * Print the selected security properties to the log files in
4215 the server. Affected file silcd/protocol.c.
4217 * Add SKE's reference counter even if calling the completion
4218 callback manually. Otherwise it goes negative, although it
4219 does not cause any problems. The affected file is
4220 lib/silcske/silcske.c.
4222 * Remove the client entry with short timeout after giving the
4223 KILL command. Affected file lib/silcclient/command.c.
4225 * Fixed to send error reply in WHOIS and IDENTIFY commands in
4226 case all found clients are already disconnected (WHOWAS would
4227 found them) in the server. Affected file silcd/command.c.
4229 * Update the last_receive (time of last data received) to be
4230 updated only when received private or channel message so that
4231 the idle time showed in WHOIS makes more sense.
4233 * Added boolean field `valid' in to the SilcClientEntry in the
4234 client library to indicate whether the entry is valid or not.
4235 This fixes the nickname change bug on channel when changing
4236 the nickname to be same than the old (like nick to Nick) the
4237 nickname formatter doesn't set the new nick anymore to Nick@host.
4238 Affected file lib/silcclient/idlist.[ch].
4240 * Now actually fixed the nickname changing on disconnection.
4241 Added new function silc_change_nick to the Irssi SILC Client.
4242 Affected file irssi/src/silc/core/client_ops.c,
4243 irssi/src/silc/core/silc-nicklist.[ch].
4245 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4247 * Check that the public key exists in the GETKEY command before
4248 trying to encode it. Affected file silcd/command.c.
4250 * Print some notifications on received public keys with GETKEY
4251 command in the Irssi SILC Client. Affected files are
4252 irssi/src/fe-common/silc/module-formats.[ch],
4253 irssi/src/silc/core/client_ops.c.
4255 * Use IDENTIFY command to resolve the server information in the
4256 GETKEY command instead of INFO command. Affected file
4257 lib/silcclient/command.c.
4259 * All command reply functions in the client library now calls
4260 the pending command reply callbacks even if an error has
4261 occurred. The server has done this a long time and now it was
4262 time to move the client library to this as well. Now all
4263 errors can be delivered back to the pending command reply
4264 callbacks if necessary. Affected files are
4265 lib/silcclient/command[_reply].[ch].
4267 * Change the nickname on disconnection back to the username
4268 because in reconnect the server will enforce it to it anyway.
4269 Affected file irssi/src/silc/core/silc-servers.c.
4271 * Fixed a config file parsing bug in the Irssi SILC client.
4272 Affected file irssi/src/silc/core/clientconfig.c.
4274 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4276 * When printing the channel mode on JOIN, verify that the
4277 channel key and channel's HMAC are valid. Affected file
4278 irssi/src/silc/core/client_ops.c.
4280 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4282 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
4283 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
4284 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
4286 * Removed channel key rekey task deleting from the function
4287 silc_server_save_channel_key. Affected file silcd/server.c.
4288 Added explicit timeout task context instead that is used to
4289 delete the task if we are registering a new task before the
4290 new task has elapsed.
4292 * When channel key rekey occurs the client library now saves
4293 the old channel key for a short period of time (10 seconds) and
4294 is able to use it in case some is still sending channel
4295 messages encrypted with the old key after the rekey. Affected
4296 file lib/silcclient/[idlist.h|client_channel.c].
4298 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4300 * Added check to the silc_server_new_id_real to not accept
4301 new ID if it is the sender's own ID. Affected file is
4302 silcd/packet_receive.c.
4304 * Assure that we do not announce ourself or the one we've
4305 sending our announcements when we're router and are announcing
4306 servers to our primary router. Affected file silcd/server.c.
4308 * Fixed silc_server_command_identify_check_client to assemble
4309 correct WHOIS packet. It send corrupted WHOIS packet and
4310 caused problem with router to router connections. Affected
4311 file silcd/command.c.
4313 Fixed also silc_server_command_whois_check the same way
4314 as for the IDENTIFY command.
4316 * Added new SilcIDListStatus to the server in the SilcIDListData
4317 structure. The status now includes the current status of
4318 the entry (like registered, resolved etc.). Affected file
4319 silcd/idlist.[ch]. Defined a bunch of different status types
4320 as well. This replaced the old boolean registered field as well.
4322 Added resolve_cmd_ident field to the SilcClientEntry structure
4323 too so that if the entry is for example being resolved so
4324 another command may attach to the same pending command reply
4325 without requiring to resolve the same entry again. This concept
4326 should optimize the WHOIS and the IDENTIFY resolving under
4327 heavy load by taking away unnecessary resolving for entries
4328 that are being resolved already.
4330 Added support for adding multiple pending commands for one
4331 command idenfier. Affected file silcd/command[_reply].[ch].
4333 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4334 before deleting the data. Otherwise the hash table will have
4335 freed data in comparison functions. Affected file is
4336 silcd/command_reply.c.
4338 * Fixed silc_idlist_replace_client_id to add the new entry to
4339 the cache with NULL nickname. Otherwise there will be invalid
4340 memory as the nickname after the nickname is freed. Affected
4341 file silcd/packet_receive.c.
4343 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4344 saved into wrong slots because the previous number of entries
4345 was not taken into account. Affected file silcd/idlist.c.
4346 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4348 * If we are router and we receive JOIN notify to a channel that
4349 does not have any users then notified client is marked as the
4350 channel founder, as it is it. The affected file is
4351 silcd/packet_receive.c
4353 * Added to the extended hash table API's table_del_*ext functions
4354 the destructor as argument too, so that the caller can decide
4355 which destructor to use or whether to use destructor at all.
4356 Affected file lib/silcutil/silchashtable.[ch].
4358 * Fixed ID Cache purging. It actually deleted the entries from
4359 the hash table after the data was freed. The hash table ended
4360 up comparing freed memory. The affected file is
4361 lib/silccore/silcidcache.c.
4363 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4365 * Fixed Irssi SILC client's KILL command's HELP syntax.
4367 * The USERS command now resolves the detailed user information
4368 if the userinfo field is missing. Affected file is
4369 lib/silcclient/command_reply.c.
4371 * Do not print error in silc_file_read if the read file does
4372 not exist. Just silently return NULL. Affected file is
4373 lib/silcutil/silcutil.c.
4375 * Fixed the silc_log_output to not wine about NULL filename
4376 and to not create some bogus " " filename. Affected file is
4377 lib/silcutil/silclog.c.
4379 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4381 * Fixed various printing bugs on the user interface in the
4382 Irssi SILC Client. Minor changes that were forgotten from
4385 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4387 * Fixed the configure.in.pre and the compilation and distribution
4388 environment to support the new autoconf 2.52. That version is
4389 now required to compile the CVS trunk.
4391 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4393 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4394 to generally parse user@fqdn format strings. Affected file
4395 lib/silcutil/silcutil.c.
4397 * Added nickname_format and nickname_force_format fields to the
4398 SilcClientParams structure. The first one defines the format
4399 for the nicknames that the library will enforce if the receives
4400 multiple same nicknames. The second one is boolean value and
4401 can be used to force the library to always enforce the format
4402 to the nicknames regardles whether there are multiple nicknames
4403 or not. This configurable formatting was employed to flexibly
4404 support accessing multiple nicknames from the user interface.
4405 The userinterface can now set the nicknames to what ever format
4406 they prefer. Affected file lib/silcclient/silcapi.h.
4408 Added function silc_client_nickname_format to the file
4409 lib/silcclient/idlist.c. It performs the nickname formatting.
4411 Added new field `hostname´ to the SilcClientEntry context.
4412 It holds the hostname of the client. Affected file is
4413 lib/silcclient/idlist.h.
4415 * Irssi SILC Client sets the nicknames in nick@hostn format.
4416 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4417 irssi/src/silc/core/silc-core.c.
4419 The WHOIS printing now also shows both the real nickname and
4420 the formatted nickname so that user knows how to access the
4421 user if there are multiple same nicknames cached. Affected
4422 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4423 printing formatting too to take the hostname now as a separate
4424 argument. The Affected file is
4425 irssi/src/fe-common/silc/modules-formats.[ch].
4427 * Changed the silc_client_get_clients_local to accept the formatted
4428 nickname as argument. It accepts the real nickname too but the
4429 formatted nickname can be used to find the true entry from
4430 multiple entries. Affected file lib/silcclient/silcapi.h and
4431 lib/silcclient/idlist.c.
4433 * Added nickname_format_parse field to the SilcClientParams.
4434 It is a callback function provided by the application to parse
4435 the nickname out of the formatted nickname string. The library
4436 calls it to get the nickname from the formatted string. Since
4437 the application generally knows better the format of the nickname
4438 string it parses it instead of the library, even though library
4439 encodes the formatted string. If the callback function is not
4440 provided then the library will use the string as is. The
4441 affected file is lib/silcclient/silcapi.h.
4443 * All the nickname strings passed to the client library in
4444 commands are now expected to be formatted nickname strings.
4445 If the command does not support the formatted nickname string
4446 it will assume that the sent string is the actual nickname.
4447 Affected file lib/silcclient/command.c.
4449 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4451 * Added public key authentication support to OPER and SILCOPER
4452 commands in the client library. Affected file is
4453 lib/silcclient/command.c.
4455 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4457 * Changed the get_auth_methdod client operation to be asynchronous.
4458 It can be async if the application resolves the authentication
4459 method from the server during the negotiation. Added new
4460 SilcGetAuthMeth completion callback that the application will
4461 call after resolving the authentication method.
4463 Added function silc_client_request_authentication_method that
4464 the application can use to resolve the authentication method
4465 from the server. Added also SilcConnectionAuthRequest callback
4466 that the library will call after the server has replied. The
4467 application can call this function if it does not know the
4468 current authentication method.
4470 Affected files are lib/silcclient/client.c and
4471 lib/silcclient/silcapi.h.
4473 * The Irssi SILC client now automatically resolves the authentication
4474 method incase any configuration information is not present (and
4475 currently there never is). The affected file is
4476 irssi/src/silc/core/client_ops.c.
4478 * Fixed public key authentication from the client library.
4479 Affected file lib/silcclient/protocol.c. Changed also the
4480 protocol specification about the public key authentication in
4481 the connection authentication protocol. The actual data to be
4482 signed is now computed with a hash function before signing.
4484 * Fixed the public key authentication from the server as well.
4485 Affected file silcd/protocol.c.
4487 * Removed the mlock()'s from the memory allocation routines.
4488 Affected file lib/silcutil/silcmemory.c. The ./configure does
4489 not check anymore for the mlock(). Affected file is
4492 * Fixed USERS command in server to allow the execution of the
4493 command for private and secret channels if the client sending
4494 the command is on the channel. Affected file silcd/command.c.
4496 * Fixed silc_client_get_clients_local to return the clients
4497 count correctly. It could return wrong value. Affected file
4498 lib/silcclient/idlist.c.
4500 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4502 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4503 types. The assembler optimizations seemed not to like 64-bit
4504 data types. The assmebler optimizations thus are now enabled
4505 also for BSD systems as opposed to only enable them for Linux.
4507 * Do not check for threads at all on BSD systems. Affected
4508 file configure.in.pre.
4510 * Removed -n and -h options from the Irssi SILC Client since
4511 they are not used in silc.
4513 * Fixed the prime generation to assure that the first digit
4514 of the generated random number is not zero since our conversion
4515 routines does not like number strings that starts with zero
4516 digit. If zero digit is seen the random number is regenerated.
4517 This caused some corrupted RSA keys when the zero first digit
4518 was met. Affected file lib/silcmath/silcprimegen.c.
4520 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4522 * Fixed WIN32 configuration in the ./configure script.
4523 Fixed to include xti.h on environments that has it.
4524 Patches by Carsten Ilchmann and andrew.
4526 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4528 * Changed the silc_id_create_client_id to be collision
4529 resistant. It is now assured that there cannot be created
4530 two same client ID's. I suspect that some weird bugs in
4531 the server were actually caused by duplicate Client IDs.
4532 Affected file silcd/serverid.[ch]. A router receiving
4533 new ID now also assures and informs the sending server
4534 if the ID caused collision.
4536 * Changed the silc_id_create_channel_id to also assure that
4537 there are no collisions.
4539 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4541 * Statement about ignoring the Mutual Authentication flag when
4542 performing rekey with PFS was a bit misleading. It is ignored
4543 if it was set in the initial negotiation, it cannot be even
4544 set in the rekey. Fixed in the ke-auth draft. Started the
4545 new versions of the protocol drafts in the doc/.
4547 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4549 * Fixed a bug in silc_client_command_identify_save when saving
4550 new channel information. The channel name was no duplicated
4551 and caused crash on exit. Affected file is
4552 lib/silcclient/command_reply.c.
4554 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4556 * Fixed the getkey command handling in the server. Send just
4557 empty OK reply to the sender if the key could not be fetched
4558 (but everything else was ok, like the key just was not available).
4559 Changed the public key parameter to optional in the protocol
4560 specs so that empty OK reply can be sent. Affected file
4563 Added a message to Irssi SILC client to tell to user if the
4564 server did not return a public key.
4566 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4568 * Fixed a channel key regeneration bug. It registered new
4569 timeout tasks exponentially until all system resources were
4570 used. Affected file silcd/server.c.
4572 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4574 * Added the SILC Document generator to the scripts/silcdoc.
4575 It can be used to generate the Toolkit Reference Manual out
4576 of the source tree. Internally it will also use the RoboDoc
4577 generator now imported in util/robodoc.
4579 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4581 * Added couple of return's in rekey protocol if error orccurred
4582 during the protocol. The execution must be terminated.
4583 Affected file silcd/protocol.c. Also, terminate the protocol
4584 always with timeout.
4586 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4588 * The client's Client ID was created initally from the wrong
4589 nickname (it could have been in format nick@host) in the
4590 silc_server_new_client. Affected file silcd/packet_receive.c
4592 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4594 * Added some SILC_LOG_ERROR's to various error conditions
4595 if client could not be added to ID cache. Affected files
4596 silcd/packet_receive.c and silcd/server.c.
4598 * When client's sock->user_data is freed, NULL also the
4599 client->router and client->connection pointers. Added check
4600 for these pointers being NULL to various places around the
4601 code. Affected file silcd/server.c.
4603 * Added client->data.registered == TRUE checks to various
4604 places around the code to assure that unregistered client's
4605 are not handled when it is not allowed. Affected file
4608 * Added `bool registered' fields to all
4609 silc_idlist_[server|client]_get_* routines to indicate whether
4610 the fetched client needs to be registered or not. Affected
4611 file silcd/idlist.[ch].
4613 * Add your own entry as registered to the ID cache in the
4614 server. Affected file server.c.
4616 * Fixed a bug in silc_server_new_server. The SilcServer was
4617 set as the new server's context instead of SilcServerEntry.
4618 This naturally caused some weird bugs.
4620 * Added "updated" field the SilcChannelEntry which indicates
4621 the time since the channel entry was last accessed. This
4622 can be used to determine whether it is necessary to
4623 announce the channel after backup resuming protocol.
4624 Affected files silcd/idlist.[ch].
4626 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4628 * Do not delete the channel rekey task when adding it
4629 for in silc_server_create_channel_key.
4631 * Changed the silc_server_create_channel_key to return
4632 TRUE or FALSE to indicate the success of the channel key
4635 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4637 * Fixed MSVC++ project files and added missing files to
4638 Makefiles under win32/.
4640 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4642 * Do not add TCP_NODELAY flag if the operating system
4643 does not have it defined. Affected files are
4644 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4646 * Fixed buffer overflow from Irssi SILC Client. Affected
4647 file irssi/src/fe-common/core/themes.c.
4649 * Fixed double free in client library in the file
4650 lib/silcclient/client.c when disconnecting from server.
4652 * Applied double free patch from cras to Irssi SILC client.
4653 Affected files irssi/src/core/[modules/expandos].c
4655 * Fixed the disconnection handling to Irssi SILC Client.
4656 The application must call silc_client_close_connection
4657 in ops->connect client operation in case of failure of
4658 the connection. Affected file is
4659 irssi/src/silc/core/client_ops.c.
4661 * Do not set sock->protocol to NULL in the function
4662 silc_client_close_connection after executing the protocol's
4663 final callback since the sock might not be valid anymore.
4664 Affected file lib/silcclient/client.c.
4666 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4668 * Do not enable SILC_THREADS if the linking with libpthread
4669 did not happen. Affected file configure.in.pre.
4671 * Added notion to protocol specification that server must
4672 verify the sent authentication payload with CMODE when
4673 setting the channel founder key. Implemented it to the
4674 server. Affected file silcd/command.c.
4676 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4678 * Added _EXTRA_DIST SILC distribution variable to the
4679 distributions file. It is used to conditionally add extra
4680 files or directories to the specific distribution. Affected
4681 files ./prepare, Makefile.am.pre and distributions.
4683 Removed the `_' from the start of the distribution names.
4686 * Added README.WIN32 for instructions to compile the Toolkit
4689 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4691 * Fixed a double free in disconnection in the server. Affected
4692 file is silcd/server.c.
4694 * Fixed the lib/silcske/groups.c to work now also with GMP
4695 MP library. The string conversion did not work when using
4696 specific base and the base is indicated in the string as well.
4698 * Created win32/ directory which now includes MSVC++ specific
4699 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4700 It will appear only in the toolkit distribution
4702 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4704 * Changed the key material distribution function in case when
4705 the hash output is too short. The data is now concatenated
4706 a bit differently than it used to. Made the change to the
4707 SKE protocol specification.
4709 * Added better GMP detection to configure.in.pre. A patch
4712 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4714 * Fixed a minor bug in SKE that might cause some problem on
4715 some platforms. Affected file lib/silcske/silcske.c.
4717 * Added the cookie checking for initiator in the SKE. It checks
4718 that the responder returns the sent cookie unmodified. The
4719 affected file is lib/silcske/silcske.c. Added new SKE
4720 error type INVALID_COOKIE that can be sent during the
4721 negotiation. Fixed some memory leaks as well.
4723 * Added the "invalid cookie" error message to Irssi SILC client's
4726 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4728 * Added `task_max' field to the SilcClientParams to indicate
4729 the maximum tasks the scheduler can handle. If set to zero,
4730 default values are used. Affected file lib/silcclient/silcapi.h.
4732 * Fixed memory leaks in silc_client_close_connection. Affected
4733 file lib/silcclient/client.c.
4735 * Added silc_client_del_client_entry to client library to free
4736 all memory of given client entry. Affected file is
4737 lib/silcclient/idlist.[ch].
4739 * Added new functions silc_client_del_channel and
4740 silc_client_del_server to delete channel and server entries.
4741 Affected file lib/silcclient/[silcapi.h/idlist.c].
4743 * Removed silc_client_del_client_by_id from silcapi.h.
4745 * Fixed the INFO command to return the server's own info
4746 correctly when querying by Server ID. Affected file is
4749 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4751 * Removed the non-blocking settings in WIN32 code in the
4752 silc_sock_[read/write] and added SleepEx instead. Affected
4753 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4754 of input data is now checked with FIONREAD and ioctlsocket.
4756 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4758 * Call silc_schedule_task_del_by_context in the
4759 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4760 Affected file lib/silccore/silcprotocol.c.
4762 * Call silc_protocol_cancel for active protocols in the
4763 silc_server_close_connection if the funtion
4764 silc_server_free_sock_user_data has not been called.
4765 Affected file silcd/server.c.
4767 * Generic tasks cannot be deleted using the del_by_fd
4768 task deleting function since generic tasks does not match
4769 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4771 * Added a notion to SILCOPER help file that the SILCOPER works
4772 only on router server, not on normal server.
4774 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4776 * Added for WIN32 support for the new scheduler as well.
4777 Affected file lib/silcutil/win32/silcwin32schedule.c.
4779 * Fixed the SHA1 implementation to work on various platforms.
4781 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4783 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4784 API. It is part of the scheduler now. Everything else is
4785 as previously but some functions has changed their names.
4786 Checkout the lib/silcutil/silcschedule.h for the interface.
4787 Updated all applications to use the new interface. Affected
4788 files are lib/silcutil/silcschedule.[ch].
4790 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4792 * Found a bug in the SKE implementation. The HASH value,
4793 specified by the protocol, was not computed correctly. The
4794 public key of the responder was not added to the computation
4795 even though it is mandatory. Affected file lib/silcske/silcske.c.
4796 This unfortunately causes incompatibilities with older
4797 clients and servers.
4799 * Added WIN32 specific network init and uninit functions:
4800 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4801 the Winsock2. Affected file lib/silcutil/silcnet.h and
4802 lib/silcutil/win32/silcwin32net.c.
4804 * Set the socket always to nonblocking mode on WIN32 after
4805 reading data or writing data. Affected file is
4806 lib/silcutil/win32/silcwin32sockconn.c.
4808 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4810 * Fixed various compilation problems under WIN32. Affected
4811 files lib/silcutil/win32/silcwin32thread.c and
4812 lib/silcutil/win32/silcwin32schedule.c.
4814 * Removed all _internal.h #includes from public header
4815 files. Internal headers must never be included from
4818 Removed also the lib/silcske/payload_internal.h file.
4820 * All include files that may be needed (public and some others
4821 included by the public headers) by application developers are
4822 now copied to the ./includes directory. It does not copy any
4823 internal headers. Affected file Makefile.defines.pre and all
4824 Makefile.am's under lib/ and subdirs.
4826 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4828 * Do not change the ~/.silc directory's permissions automatically.
4829 Affected file irssi/src/silc/core/clientutil.c.
4831 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4833 * Do not cancel the protocol in silc_server_close_connection
4834 it might cause recursion. Now cancelled in the function
4835 silc_server_free_sock_user_data. Affected file silcd/server.c.
4837 * Fixed the silc_server_remove_clients_by_server to regenerate
4838 the channel keys correctly finally. Added also new function
4839 silc_server_remove_clients_channels to actually do it.
4840 Affected file silcd/server.c.
4842 * Fixed the silc_server_new_channel to not crash by giving
4843 wrong router to the new channel. Affected file is
4844 silcd/packet_receive.c.
4846 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4848 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4849 which is given as argument to the silc_client_alloc now.
4850 It can be used to configure the client and set various parameters
4851 that affect the function of the client.
4853 * The USERS command in server did not check whether the channel
4854 is private or secret. Affected file silcd/command.c.
4856 * Added new argument to the USERS command in protocol specification.
4857 The USERS command now can take the channel name as argument
4858 as well. Added support for this in client and server and
4859 updated the protocol specs.
4861 * Completed the GETKEY command in client. It can be now used
4862 to fetch also servers public key not only some clients.
4863 Affected files lib/silcclient/command[_reply].c.
4865 * Added silc_client_get_server to return server entry by the
4866 server name. Affected files lib/silcclient/silcapi.h and
4869 * Redefined the IDENTIFY command in protocol specification to be
4870 more generic. It now can be used to query information about
4871 any entity in the SILC Network, including clients, servers and
4872 channels. The query may be based either the entity's name
4873 or the ID. Added support for this in both client and server.
4875 Affected files silcd/command.c and lib/silcclient/command.c
4876 and command_reply.c.
4878 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4879 the _from_client and _from_server functions. Affected file
4882 * Added silc_client_get_channel_by_id_resolve to the file
4883 lib/silcclient/silcapi.h to resolve channel information by
4884 its ID. Added also silc_client_get_channel_by_id that
4885 does not resolve it from the server.
4887 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4889 * Added SilcServerEntry context into the client library
4890 to represent one server. The INFO command now allocates
4891 these to save the resolved server info. For now on the
4892 client library will also keep information about servers,
4893 connected and resolved with INFO.
4895 The INFO command now allocates the SilcServerEntry context
4896 and saves the server info there. The COMMAND_REPLY in
4897 the INFO now returns the parameters to application in
4898 same order as defined in the protocol specification.
4900 The entries are cached in the client->server_cache.
4902 * The INFO command is now issued after received the Client ID
4903 from the server. Affected file lib/silcclient/client.c.
4905 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4906 to the application as the mode changer might be server.
4907 It is guaranteed that NULL is not returned anymore to the
4908 application. Affected file lib/silcclient/client_notify.c.
4910 The ID Type is now also passed to the application so that
4911 it can check whether the returned entry is SilcClientEntry
4914 Added new function silc_client_get_server_by_id to return
4915 the server entry by ID. Affected files are the
4916 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4918 * Do not create the channel in the Irssi SILC Client when issuing
4919 the JOIN command but when received the sucessful JOIN command
4920 reply. Otherwise the channel might get created even though we
4921 could not join it. The Affected file is
4922 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4924 * Fixed a channel joining bug in router. The router must also
4925 check the channel modes, invite and ban lists etc. when serving
4926 the JOIN command sent by normal server. Affected file is
4927 silcd/command.c. The router now resolves the client's
4928 information from the server who sent the JOIN command if it
4929 does not know it, and processes the JOIN command only after
4932 * Changed the SilcCommandCb to take new argument; void *context2.
4933 Affected file lib/silccore/silccommand.h
4935 The second argument in the command callbacks in the server now
4936 includes the SilcServerCommandReplyContext if the command was
4937 called as pending command callback from the command reply.
4938 Otherwise it is NULL. When called as pending the status of the
4939 command reply will be checked and if it was erronous the
4940 error will be sent to the original sender of the command.
4941 This way the client always receives the error messages even
4942 though the server was actually the one who received the error
4943 when it resent the command to router, for example. Affected
4944 files silcd/command[_reply].[ch].
4946 * Fixed sending WHOWAS command's error message to client if
4947 the requested client could not be found. It was missing.
4950 * Changed the CMODE and CUMODE commands reply arguments in the
4951 protocol specification. The Channel ID is now sent in both
4952 of the commands to identify the channel. Implemented this
4953 new feature to the client and server. Affected files
4954 lib/silcclient/command_reply.c and silcd/command.c.
4956 * Made better checks for invite and ban lists in the JOIN
4957 command in server. Affected file silcd/command.c.
4959 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4961 * The server now performs the incoming host IP/DNS lookup
4962 using the silc_socket_host_lookup and thus does not block
4963 the server anymore. Affected file silcd/server.c.
4965 * Completed the multi-thread support for SILC Scheduler in
4966 the lib/silcutil/silcschedule.c.
4968 * Fixed the configure.in.pre to detect the pthread correctly
4971 * Fixed a deadlock in silc_task_queue_wakeup in the file
4972 lib/silcutil/silctask.c.
4974 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4976 * Added new function silc_schedule_wakeup that is used in
4977 multi-threaded environment to wakeup the main thread's
4978 schduler. It needs to be used when a thread adds a new task
4979 or removes a task from task queues. After waking up, the
4980 scheduler will detect the task queue changes. If threads
4981 support is not compiled in this function has no effect.
4982 Implemented the wakeup mechanism to both Unix and WIN32
4983 systems. Affected files are lib/silcutil/silcschedule.[ch],
4984 lib/silcutil/unix/silcunixschedule.c and the
4985 lib/silcutil/win32/silcwin32schedule.c.
4987 * Added new function silc_task_queue_wakeup to wakeup the
4988 scheduler by the specified task queue. Affected file
4989 lib/silcutil/silctask.[ch].
4991 * The silc_socket_host_lookup_start now wakes up the scheduler
4992 after adding the timeout task. Affected file is
4993 lib/silcutil/silcsockconn.c.
4995 * The silc_socket_host_lookup is synchronous now if the threads
4996 support is not compiled in. However, the callback is still
4997 called asyncronously through the scheduler, anyway. Affected
4998 file lib/silcutil/silcsockconn.c.
5000 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5002 * Added new function silc_socket_host_lookup to perform
5003 asynchronous IP and FQDN lookups for the socket connection.
5004 Affected files lib/silcutil/silcsockconn.[ch].
5006 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5008 * Added SILC_MUTEX_DEFINE to define the mutex on environments
5009 that may or may not compile the mutex support in.
5011 Changed the silc_mutex_alloc interface. It allocates the
5012 mutex now to the sent pointer and returns TRUE or FALSE.
5014 Affected file lib/silcutil/silcmutex.h.
5016 * Wrote the SILC Task Queue interface to support multi-threads.
5017 Affected file lib/silcutil/silctask.[ch].
5019 * Wrote the SILC Scheduler to support multi-threads. Affected
5020 file lib/silcutil/silcschedule.c.
5022 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5024 * Implemented the SILC Mutex API and SILC Thread API for WIN32
5025 in lib/silcutil/win32/.
5027 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5029 * Defined SILC Mutex API and SILC Thread API and implemented
5030 them for Unix. Affected files are
5031 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
5032 lib/silcutil/unix/silcunixmutex.c and
5033 lib/silcutil/unix/silcunixthread.c.
5035 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5037 * Fixed the silc_server_remove_clients_by_server's channel
5038 key re-generation. The hash table handling was incorrect
5039 and would not work with many channels. Affected file is
5042 * Fixed some memory leaks around the server code.
5044 * Rewrote the silc_server_get_users_on_channel to support IPv6
5045 based Client ID's. Affected file silcd/server.c.
5047 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
5048 specification. However, a separate document must be written
5049 to define the detailed signing procedure and the payload
5050 associated with the flag. Defined the flag to the
5051 lib/silccore/silcchannel.h as well.
5053 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5055 * Changed the dynamic tables to static size tables in the
5056 lib/silccrypt/silchmac.c.
5058 * Removed GCC dependencies from the code. A patch by cras.
5060 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5062 * Do not show the error "Error receiving packet bla bla"
5063 in server if it really was not an error (-2 means that reading
5064 is pending). Affected file silcd/server.c.
5066 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5068 * Fixed a possible crash in silc_server_remove_clients_by_server
5069 in silcd/server.c. Fixed there also some memory leaks.
5071 * Fixed the silc_idlist_replace_client_id. It could replace
5072 wrong key in the hash table. Affected file silcd/idlist.c.
5074 * Do not check whether there are global users on the channel
5075 if the channel->global_users is FALSE. Affected functions
5076 silc_server_remove_from_one_channel and
5077 silc_server_remove_from_channels in silcd/server.c. Also,
5078 do not check if the removed client is local as we can be
5079 sure that global client was not removed from the channel
5080 and checking for global users is not needed.
5082 * The silc_server_remove_clients_by_server now re-generates
5083 the channel keys correctly for those channels that had
5084 clients removed from them. Affected file silcd/server.c.
5086 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5088 * Found the reason of random crashes in the server. We weren't
5089 ignoring the SIGPIPE signal (which can be sent in write())
5090 and it crashed the server. Affected file silcd/silcd.c.
5092 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5094 * Assure that sock->user_data is not NULL in the function
5095 silc_server_packet_send in silcd/packet_send.c.
5097 * Disconnect the remote connection if it could not be added
5098 to any ID lists in the server. The affected file is
5101 * Check in silc_server_packet_send[_real/dest] that the
5102 socket is not disconnecting and ignore the data if it is.
5103 Affected file silcd/packet_send.c.
5105 * Define inline to __inline on native WIN32 compilation.
5106 Affected file includes/silcwin32.h.
5108 * Added some explicit type casts for inline code since MSVC
5109 require them. Affected files lib/silcutil/silcbuffer.h,
5110 lib/trq/silcdlist.h and lib/trq/silclist.h.
5112 * Print warning in log files from now on if the packet
5113 decryption fails. Affected file silcd/server.c.
5115 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5117 * Changed the `say' client operation's interface to accept
5118 new `type' argument to indicate the type of the message sent
5119 by the library. The application may filter the library's
5120 messages according the type. The affected file is the
5121 lib/silcclient/silcapi.h.
5123 * Added two new functions to lib/silcclient/silcapi.h:
5124 silc_client_del_client and silc_client_del_client_by_id.
5125 Affected file lib/silcclient/idlist.c.
5127 * Moved the clientincludes.h from includes/ to silc/ and
5128 serverincludes.h from includes/ to silcd/.
5130 * The modes for the CMODE and CUMODE are now passed as
5131 uint32 for application with COMMAND_REPLY. The affected
5132 file is lib/silcclient/command_reply.c.
5134 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5136 * /WHOIS without arguments shows client's own information.
5137 Affected file lib/silcclient/command.c.
5139 * Changed PING to not accept any arguments. The specs
5140 says that client can ping only the connected server so
5141 requiring an argument is not needed. Affected file is
5142 lib/silcclient/command.c.
5144 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5146 * Fixed a fatal bug in private message sending and reception
5147 encryption and decryption when using private message keys.
5148 The implementation was incorrect and did not follow the
5149 specification. It causd that some of the message were
5150 lost since it did not use the sending and receiving keys
5151 as the protocol suggests. This has been fixed and will cause
5152 incompatibilities with older clients when sending private
5153 message encrypted with private message keys. Affected files
5154 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
5155 and various other in Irssi SILC Client.
5157 Added `responder' boolean argument to the functions
5158 silc_client_add_private_message_key[_ske] to indicate when
5159 the key is added as responder or initiator of the key
5162 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5164 * Removed the silc_ske_check_version function and created
5165 a SilcSKECheckVersion callback. Added also a function
5166 silc_ske_set_callbacks that is now used to set all SKE
5167 callbacks. The callback functions are not given to
5168 the SKE functions anymore, but this function is used to
5171 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
5173 * Added `silc_version' argument to the silc_client_alloc
5174 to define the version of the application for the library.
5175 The library will use the version string to compare it
5176 against the remote host's (usually a server) version
5177 string. Affected file lib/silcclient/silcapi.h
5179 * Added the KE protocol context to Key Agreement context
5180 in client library so that we can abort the SKE if it
5181 is in process when we get timeout. Affected file is
5182 lib/silcclient/client_keyagr.c.
5184 * Do not resolve the client ID forever if it returns in the
5185 first time that such client does not exist. This was done
5186 for example with private message. Affected file is
5187 lib/silcclient/client_prvmsg.c.
5189 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5191 * Do not add regex.h for WIN32. The affected file
5192 includes/silcincludes.h.
5194 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
5195 not work yet 100%. It generates the DLL's automatically
5196 when compiling with --with-win32 under cygwin.
5198 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5200 * lib/contrib/regex.c is not compiled on WIN32.
5202 * Added silc_net_get_socket_opt function to the
5203 lib/silcutil/silcnet.h.
5205 * Added includes/silcwin32.h for WIN32 specific includes
5208 * Do not use ptime structure or any of the posix process
5209 functions on WIN32 in lib/silccrypt/silrng.c.
5211 * Added silc_gettimeofday to provide generic function
5212 for struct timeval on all platforms. Added the function
5213 to lib/silcutil/silcutil.h.
5215 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5217 * Moved the lib/silccore/silcsockconn.[ch] to the utility
5218 library as they clearly belong there. As a plus side we
5219 can make the actual socket connection routines platform
5222 Added also new generic function silc_socket_read and
5223 silc_socket_write (that used to be silc_packet_[read/write].
5224 The implementation of these are platform specific.
5226 * Added WIN32 specific routines of silc_socket_[read/write]
5227 to lib/silcutil/win32/silcwin32sockconn.c.
5229 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5231 * Added preliminary support for native WIN32 compilation under
5232 cygwin (using the -mno-cygwin option for GCC) to the
5233 ./configure.in.pre. The --with-win32 now prepares the
5234 compilation for native WIN32.
5236 * Rewrote the SILC Scheduler interface in the file
5237 lib/silcutil/silcschedule.h. The scheduler is now context
5238 based and does not have anymore any global static scheduler.
5239 Moved the Unix scheduler to the lib/silcutil/unix/ directory
5240 and created lib/silcutil/win32 directory for WIN32 based
5243 * Added Unix specific network routines to the
5244 lib/silcutil/unix/silcunixnet.c and the old
5245 lib/silcutil/silcnet.c includes now only generic routines.
5247 Added WIN32 specific network routines to the
5248 lib/silcutil/win32/silcwin32net.c.
5250 * Added Unix specific utility functions from the
5251 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
5253 * Added WIN32 SILC Scheduler to the file
5254 lib/silcutil/win32/silcwin32schedule.c. The code is of course
5257 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5259 * Do not handle JOIN notify in the server if the target client
5260 is not registered (idata->registered == FALSE). The affected
5261 file is silcd/packet_receive.c.
5263 * Update the nickrec->founder in event_cumode in the Irssi SILC
5264 client. Affected file irssi/src/silc/core/silc-channels.c.
5266 * Fixed the CUMODE_CHANGE notify handling in the server when
5267 server and router are announcing their clients on channels.
5268 Now the mode changes are saved and notified correctly. The
5269 affected file is /silcd/packet_receive.c.
5271 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
5272 They really did not replace the cache entry in the ID Cache.
5273 Now they do that. Affected file silcd/idlist.c.
5275 * Fixed the KICK notify handling in the Irssi SILC client to
5276 update the channel records so that the kicked client does not
5277 appear to be on the channel. The affected file is
5278 irssi/src/silc/core/silc-channels.c.
5280 * Always update the conn->current_channel when executing command
5281 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
5283 * Fixed the KILL notify handling in Irssi SILC client to remove
5284 the killed client on all channels.
5286 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5288 * Fixed the silc_parse_command_line to remove extra spaces
5289 from the start and end of the arguments. Affected file is
5290 lib/silcutil/silcutil.c.
5292 * Cancel and free any active protocol in the function
5293 silc_server_close_connection. Affected file silcd/server.c.
5295 * Cancel and free any active protocol in the function
5296 silc_client_close_connction. Affected file is
5297 lib/silcclient/client.c.
5299 * Do not execute the KILL command for clients that are in
5300 history (ie. they are not in the network). Affected file is
5303 * Fixed KILL notify handling, client does not crash anymore.
5304 Affected file irssi/src/silc/core/silc-channels.c.
5306 * Reduced the default packet buffer size from 2048 to 1024 in
5307 lib/silccore/silcpacket.c.
5309 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5310 counter to the SKE context that is incresed when the SKE library
5311 performs async operation outside the library. If the outside
5312 process frees the SKE context and FREED status will be set
5313 and the library will detect after the sync operation that the
5314 libary is freed. The affected files are
5315 lib/silcske/silcske[_status].[ch].
5317 * Resolve the client entry information in the function
5318 silc_client_channel_message to assure that NULL pointer is not
5319 passed as client entry to the application. */
5321 * Fixed the task timeout calculation to assure that there is
5322 never negative timeouts. The affected file is
5323 lib/silcutil/silcschedule.c.
5325 * Fixed the channel user mode notification sending in server.
5326 It was sent point-to-point to the router (or to server by router)
5327 but it needs to be destined to a channel. The routines now
5328 supports sending the channel user mode notifys to the channels
5329 when announcing clients and channels. Affected files are
5330 silcd/server.c and silcd/packet_receive.c.
5332 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5333 It did not actually replace the old channel entry in the cache.
5334 Affected file lib/silcclient/client_notify.c.
5336 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5338 * Fixed a possible crash in silc_packet_send_prepare. It now
5339 assures always that there is enough space in the buffer and
5340 at the tail area of the buffer (for MAC).
5342 Fixed the inbound buffer reallocation in silc_packet_read.
5343 It was old code and did not handle the reallocation correctly.
5346 The affected file is lib/silccore/silcpacket.c.
5348 * Fixed buffer overflow in silc_parse_nickname in the file
5349 lib/silcutil/silcutil.c.
5351 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5353 * make install generates new server keys only if there is not
5356 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5358 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5359 Added check that if the NOREPLY is set then we will not send
5360 the away message. This avoids infinite loop of away messages
5361 if both clients are away. The affected file is
5362 lib/silcclient/client_prvmsg.c.
5364 * Fixed client crash if /NICK was given without arguments.
5365 Affected file lib/silcclient/command.c.
5367 * Server does not send the invite list in INVITE command back
5368 to the client if the list was not altered. Added this notion
5369 to the protocol spec as well. Affected file silcd/command.c.
5371 Fixed possible crash in INVITE command by checking the
5372 value of silc_server_get_client_route command.
5374 * Fixed the INVITE notify type handling. The arguments are now
5375 taken in correct order and client does not crash. The affected
5376 file is irssi/src/silc/core/silc-channels.c.
5378 Removed the "Inviting xxx to channel" message from the
5379 client library away and let the application handle it.
5380 Affected file lib/silcclient/command.c. Added that message
5381 to Irssi SILC client's message formats.
5383 * Fixed CMODE command crash in client. It now checks the
5384 amount of arguments correctly and does not crash. The affected
5385 file is lib/silcclient/command.c.
5387 * Do not create new channel automatically in silc_channels_join
5388 but check whether the channel by that name already exists.
5389 Affected file irssi/silc/core/silc-channels.c.
5391 * Do not send the SERVER_SIGNOFF to router if the disconnected
5392 entity was the router. Affected file silcd/server.c.
5394 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5395 SILC client as it was missing from there.
5397 Added the handling of the KICK notify to the Irssi SILC client
5398 as it was missing. Added "you have been kicked" message to
5399 Irssi SILC client's message modules formats.
5401 Added the handing of the KILL notify to the Irssi SILC client
5402 as it was missing. Added the kill message module formats
5405 The affected file is irssi/src/silc/core/silc-channels.c.
5407 * The router did not save the channel mode the server announced.
5408 Affected file silcd/packet_receive.c.
5410 * Fixed a possible crash in INFO command in server. If the
5411 server did not provide the server info it crashed. Affected
5412 file silcd/command.c.
5414 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5416 * Fixed the GETKEY command in the server to check also the
5417 global list. Otherwise the GETKEY would not work correctly
5418 in normal SILC server. Affected file silcd/command.c.
5420 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5422 * Fixed GETKEY crash, it crashed if the command did not succseed.
5424 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5426 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5427 is now real and not just an macro interface to GMP.
5429 Removed the entire GMP from the source tree and imported new
5430 NSS MPI library instead. Reason for removing GMP is that it is
5431 extremely large and compiles extremely slow. The NSS MPI
5432 is only a few files and compiles in less than 10 seconds.
5433 The speed is also about the same as GMP. The MPI is imported
5434 to lib/silcmath/mpi.
5436 If the system has GMP installed we will still use the GMP.
5437 If it is not then the NSS MPI will be compiled.
5439 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5441 * Merged a long nickname (127 characters long) crash bugfix from
5442 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5444 * Merged a freed memory reference bugfix from Irssi CVS tree.
5445 Affected file irssi/src/core/commands.c.
5447 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5449 * Added the server's public key sving and verification to the
5450 server when performing the SKE. This was missing and the
5451 remote server's (or router's) public key was accepted without
5452 checking whether we have it previously or trust it at all.
5453 Affected file silcd/protocol.c.
5455 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5457 * Check in the silc_server_timeout_remote if protocol is active
5458 and make sure that the protocol's final callback is called so
5459 that all memory if freed. Affected file silcd/server.c.
5461 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5463 * silc_server_whois_send_reply crashed the server if the nickname
5464 was 127 characters long. Affected file silcd/command.c.
5466 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5468 * Added sanity check to the silc_server_new_client. If the hostname
5469 is provided inside username then check that the provided hostname
5470 really is the same as the resolved one. If the hostname was not
5471 resolved then check it from the public key. Affected file is
5472 silcd/packet_receive.c.
5474 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5475 if the server disconnected us and the connection is not valid
5476 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5478 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5479 the library to the lib/silcutil/silcutil.[ch].
5481 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5483 * Close log file after open. Affected file
5484 lib/silcutil/silclog.c.
5486 * Check whether sock == NULL in silc_client_send_packet and return
5487 if it is. Affected file lib/silcclient/silcclient.c.
5489 * Check rec->entry == NULL in the Irssi SILC Client before
5490 sending the channel message. Affecte file is
5491 irssi/src/silc/core/silc-servers.c.
5493 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5495 * Merged a splitted window bugfix from Irssi CVS tree. The
5496 affected file is irssi/src/fe-text/textbuffer-view.c.
5498 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5499 It did not print nickname.
5501 * Improved the distributions system a bit.
5503 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5505 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5506 irssi/src/fe-text/gui-window.c.
5508 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5509 to in-active server. The affected file is
5510 irssi/src/silc/core/client_ops.c.
5512 * Resolve the client in USERS command reply if the entry does
5513 not have username resolved. The affected file is
5514 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5515 command to WHOIS command to really resolve stuff. The USERS
5516 is not used any more in any critical section so WHOIS can
5517 be used even though it might be slower than IDENTIFY.
5519 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5522 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5524 * Changed the protocol API a bit more consistent in the
5525 lib/silccore/silcprotocol.[ch].
5527 * Changed the following headers to ROBODoc format:
5529 lib/silccore/silcpayload.h
5530 lib/silccore/silcprotocol.h
5531 lib/silccore/silcsockconn.h
5533 All core library headers are now formatted.
5535 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5537 * Fixed a bug in Irssi SILC client; do not show that you are
5538 server/router operator if you really are not. Affected file is
5539 irssi/src/silc/core/client_ops.c.
5541 * Renamed silc_command_free_payload to silc_command_payload_free.
5542 Affected file lib/silccore/silccommand.h
5544 * Added silcmath.h to include the prototoypes of various routines
5545 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5548 * Changed the following headers to ROBODoc format:
5550 lib/silccore/silcchannel.h
5551 lib/silccore/silccommand.h
5552 lib/silccore/silcid.h
5553 lib/silccore/silcidcache.h
5554 lib/silccore/silcmode.h
5555 lib/silccore/silcnotify.h
5556 lib/silccore/silcpacket.h
5557 lib/silcmath/silcmath.h
5559 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5561 * Added checking to the server code not to start the server if
5562 ciphers and stuff are not configured properly. Affected files
5563 silcd/serverconfig.[h] and silcd/server.c.
5565 * Changed the layout of the header files of the public interfaces
5566 in the SILC libraries. The new layout supports ROBODoc
5567 documentation tool (and some others) so that it is easy to create
5568 a library reference manual. All the other headers and source
5569 code must still follow the CodingStyle document. Also source
5570 code must not include these ROBODoc stuffs, only the headers.
5571 Furthermore, all public interface headers must now be named
5572 by using `silc' prefix, example: silcapi.h, silccipher.h.
5573 Some files were renamed due to this. All the other headers
5574 must not be used as public interfaces. I will update the
5575 CodingStyle document later. Changed following headers, so far:
5577 lib/silcclient/silcapi.h
5578 lib/silccore/silcauth.h
5579 lib/silccore/silcprivate.h
5580 lib/silccrypt/silcdh.h
5582 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5586 * Removed silc_client_packet_send_flush from the client library
5587 as it is not needed. Affected file lib/silcclient/client.[ch].
5589 * Added printing of message of unresolved authentication method
5590 to the Irssi SILC client. Added it to the module formats.
5591 Removed the same message from the client library.
5593 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5595 * Added new distribution feature, DISTLABEL. Every distribution
5596 can define own preprocessor label that can be used in the
5597 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5598 file distributions, acconfig.h.pre and prepare.
5600 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Added Makefile.defines_int to include the actual definitions
5603 for Makefile.defines.in. Tested the new distribution system,
5604 created distributions and tested installation.
5606 * Added AWAY message printing to the Irssi SILC client. Added
5607 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5609 * Added SCONNECT command to call the SILC's CONNECT command.
5610 Cannot use CONNECT directly since Irssi uses that internally.
5611 Affected file irssi/src/silc/core/silc-servers.c.
5613 Added ACTION local command. It is same as ME command but takes
5614 the channel as mandatory argument.
5616 Rewrote some of the Irssi's help files to suite for SILC
5619 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5621 * Added Makefile.defines[.in] that should for now on be included
5622 in all Makefile.am file in the source tree. That file includes
5623 all common compilation definitions for SILC source tree.
5625 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5627 * Minor changes to the ./prepare script to change the package
5628 name according the distribution name to the configure.in.
5630 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5632 * Created new distribution system. Added file `distributions'
5633 that defines all the distributions that can be created out of
5634 the SILC source tree. The ./prepare script now reads that
5635 file to determine how to prepare the distributions. The
5636 first argument to the ./prepare is the name of the distribution
5637 and second is the version of the distribution. If given
5638 without arguments it creates the default (toolkit) distribution
5639 with the default version (defined in ./prepare).
5641 All Makefile.am files that are subject to the distributions
5642 are now named as Makefile.am.pre. These are ./Makefile.am
5643 and lib/Makefile.am. Others may be changed later.
5645 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5647 * Added invite list, ban list, some key management and connection
5648 error message printing to module formats in the Irssi SILC client.
5650 * Added new silc_client_set_away_message to set the away message
5651 that is back to the person who sent private message. The
5652 affected file lib/silcclient/silcapi.h and the
5653 lib/silcclient/client_prvmsg.c.
5655 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5657 * Fixed the private message sending in the Irssi SILC client,
5658 added local command KEY to the Irssi SILC client.
5660 Added key management and key agreement message formats to the
5661 irssi/src/fe-common/silc/module-formats.[ch].
5663 Added USERS (alias WHO) printing, server/router operator
5664 indication and LIST command printing to the module formats.
5666 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5668 * Fixed channel joining notify handling, cumode notify handling
5669 from Irssi SILC client.
5671 * Added SILC specific module-formats to the Irssi SILC client so
5672 that SILC specific message hilighting, colors etc is possible.
5673 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5675 Added channel mode, channel user mode, actions, notices,
5676 whois and whowas printing to the the module-formats.c.
5678 * Fixed a bug in channel deletion in the server. The channel
5679 is not left to the cache even if the channel founder auth mode
5680 is set when there are no users anymore on the channel. Affected
5681 file silcd/server.c.
5683 * The silc_net_localhost now resolves the entire hostname including
5684 the domain name. Affected file lib/silcutil/silcnet.c.
5686 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5688 * Changed the ask_passphrase client operation to be ascynchronous.
5689 It has now a completion callback and a context that the
5690 application must call after it has got the passphrase from
5691 the user. Affected files lib/silcclient/silcapi.h,
5692 lib/silcclient/protocol.c, lib/silcclient/command.c and
5695 Added SilcAskPassphrase callback that the application calls
5696 to deliver the passphrase to the library.
5698 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5699 The public key verification and especially a certificate
5700 verification is asynchronous procedure.
5702 Added new SILC_SKE_STATUS_PENDING status to indicate the
5703 request is pending and a callback will be called to finalize
5706 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5707 indicate that remote end did not send its public key (or
5708 certificate), even though we require it. Added check for this
5709 condition in the SKE. This was a security bug, now fixed.
5711 Defined new SilcSKEVerifyCbCompletion callback that is called
5712 when the verification process is completed.
5714 The affected files lib/silcske/silcske_status.h and
5715 lib/silcske/silcske.[ch].
5717 * Changed the verify_public_key client operation to be async
5718 as well. Defined SilcVerifyPublicKey callback that is used to
5719 indicate the success of the public key verification process.
5721 Changed the server and client to use the new async client
5724 * Changed the Irssi SILC client's internal scheduler to be called
5725 twice as many times as it used to be. As a result the client
5726 should be a bit faster now. Affected file is
5727 irssi/src/silc/core/silc-core.c.
5729 * Added support to Irssi SILC client of asynchronous public key
5730 verification and passphrase inquiry. Affected file is
5731 irssi/src/silc/core/silc-core.c.
5733 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5735 * Do not say "You have left channel %s" in client library.
5736 Moved it to the application. Affected files are
5737 lib/silcclient/command.c and silc/client_ops.c.
5739 * Fixed silc_client_get_clients. Command context was not
5740 duplicated and was freed memory in the callback. Affected
5741 file lib/silcclient/idlist.c.
5743 * Do not say "you are now talking..." on JOIN command in the
5744 client library. The appliation must handle it.
5746 * Do not say ".. changed topic to" in command reply in the
5747 client libary. The application must handle it.
5749 * Fixed TOPIC command sending in the client library.
5751 * Fixed a memory leak in silc_client_command_free in the file
5752 lib/silcclient/command.c.
5754 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5756 * Imported a modified version of Irssi client to the source tree.
5757 The Irssi will be used to create a new client called
5758 Irssi SILC. Imported to irssi/.
5760 Added silc_core_init_finish function to the Irssi. Affected
5761 file irssi/configure.in.
5763 A lot changes in the Makefile.ams around the irssi tree.
5765 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5767 * Do not rehash if the new size is same as the old size of the
5768 hash table, in the silc_hash_table_rehash*. The affected file
5769 lib/silcutil/silchashtable.c.
5771 * Replaced hash_table_del_by_context calls from the server
5772 (when channel->user_list and client->channels) to the
5773 hash_table_del as it is sufficient and faster.
5775 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5777 * Added silc_hash_table_list, silc_hash_table_get and the
5778 SilcHashTableList structure to provide an alternative way to
5779 traverse the hash table. The affected files are
5780 lib/silcutil/silchashtable.[ch].
5782 * Changed the server's idlist routines to use the hash table
5783 routines to optimize the code.
5785 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5787 * Replaced the client entry's `channel' list and channel entry's
5788 `user_list' list to hash tables for optimized lookup. Changed
5789 the code to use the hash table interface around the code.
5790 Affected file lib/silcd/idlist.[ch].
5792 * Added `auto_rehash' boolean argument to the function
5793 silc_hash_table_alloc to indicate whether the hash table should
5794 auto-rehash when it thinks is appropriate time. It will
5795 increase the hash table size if the there is twice as much
5796 entries in the table than the size of the table, and will
5797 decrease the size if there are twice as less entries than
5798 the size of the table.
5800 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5802 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5804 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5806 * silc_idcache_purge_by_context deletes the entry now by context
5807 as it is supposed to do. Affected file lib/silccore/idcache.c.
5809 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5810 client is not anymore valid (WHOWAS givens the info) and not
5811 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5813 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5815 * Removed the `data' and `data_len' arguments from the ID Cache
5816 interfaces and added `name' argument. ID Cache does not handle
5817 anymore the binary data only a names associated with given ID.
5819 * When hashing a Client ID with silc_hash_id the entire ID is
5820 not hashed anymore, instead only the hash of the Client ID is
5821 hashed. This way we can access the Client ID from the cache
5822 with Client ID but with the hash of the ID (which is a hash of
5823 the nickname) as well without any difference in performance.
5825 Added also silc_idcache_find_by_id_one_ext to do one on one
5826 searching when we have the actual ID. Added also function
5827 silc_hash_client_id_compare. The affected files are
5828 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5830 * When hashing the name associated with a ID it is always done
5831 in lowercase. This way we can access the cache without worrying
5832 about case-sensitivity, even though, for example nicknames are
5835 * Fixed a bug in server with channel message sending. It put
5836 wrong ID type as destination ID. The affected file
5837 silcd/packet_send.c.
5839 * silc_idcache_del_by_context now deletes from all hash tables
5840 by context. Affected file lib/silccore/idcache.c.
5842 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5844 * Changed the client library to use the new ID Cache interface.
5845 Changes around the source tree.
5847 * Added silc_hash_table_rehash_ext to rehash with specific
5848 hash function. Affected file lib/silcutil/silchashtable.[ch].
5850 * Added silc_hash_string_compare to compare two strings in the
5851 hash table. Affected file lib/silcutil/silcutil.[ch].
5853 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5855 * Added new function silc_idcache_del_by_context into the
5856 lib/silccore/idcache.[ch].
5858 * Changed the server's ID list routines to use the new ID Cache
5859 interface. Changes around the source tree.
5861 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5863 * Added silc_hash_table_del[_by_context]_ext functions in to the
5864 lib/silcutil/silchashtable.[ch].
5866 Removed silc_hash_table_find_all* routines and added new
5867 silc_hash_table_find_foreach to replace them.
5869 Added silc_hash_table_replace_ext function as extended
5870 replacing function. Separated the simple hash table interface
5871 from the extended hash table interface in the file
5872 lib/silcutil/silchashtable.h.
5874 * Fixed minor bugs and changed it to use some of the new
5875 hash table functions in lib/silccore/idcache.c
5877 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5879 * Added new function silc_hash_table_find_all to return all keys
5880 in the hash table by the specified key. As the hash table is
5881 collision resistant it also makes it possible to have several
5882 duplicate keys in the hash table. This function may be used to
5883 find all of the keys from the hash.
5885 Added user_context arguments to the SilcHashFunction,
5886 SilcHashCompare and SilcHashDestructor to deliver user specified
5889 Added new fuctions silc_hash_table_find[_all]_ext to do
5890 extended lookup with specified hash and compare functions and
5891 specified user contexts.
5893 Added new function silc_hash_table_add_ext to add the key
5894 with specified hash function and user context.
5896 Added new function silc_hash_table_foreach to traverse all
5897 entrys in the hash table. Added SilcHashForeach callback
5900 Added new function silc_hash_table_del_by_context to delete
5901 the entry only if the context associated with the key matches.
5903 Affected files are lib/silcutil/silchashtable.[ch].
5905 * Removed silc_hash_[server/client/channel]_id and added just
5906 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5907 silc_hash_id_compare to compare two ID's using as the hash table
5908 comparison function. Added also silc_hash_data to hash
5909 binary data and silc_hash_data_compare to compare it.
5911 * Removed silc_idlist_find_client_by_hash as it is not needed
5912 anymore. Affected file silcd/idlist.[ch].
5914 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5915 to use internally the SilcHashTable. The new ID Cache is a lot
5916 faster than the old one. Some of the ID Cache interface was also
5917 rewritten and obsolete and stupid functions were removed.
5919 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5921 * Added entry_count field to the SilcHashTable to keep the number
5922 of the entries in the table. Implemented the function
5923 silc_hash_table_rehash. Added new function
5924 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5926 Fixed a minor bug in silc_hash_table_free.
5928 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5929 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5930 into the lib/silcutil/silcutil.[ch].
5932 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5934 * Implemented a collision resistant hash table into the
5935 lib/silcutil/silchashtable[ch]. See the header and the source
5936 for the SilcHashTable API.
5938 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Merged dotconf version 1.0.2 into lib/dotconf.
5942 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5944 * Do not compile anything in lib/silcsim/* if the SIM support
5945 is not enabled. The tree should now compile without problems
5948 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5950 * Compiled the SILC under cygwin. Compiled and tested briefly
5951 without problems. More tests needed. The SIMs didn't compile
5954 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5956 * Fixed possible crash in silc_get_username in the
5957 lib/silcutil/silcutil.c.
5959 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5961 * Fixed a va_arg in silc/client_ops.c.
5963 * Oops, RC5 routines were named AES and caused some problems
5964 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5966 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5968 * Added new SilcIDIP structure into the lib/silccore/id.h and
5969 replaced the old `ip' fields from all SILC ID's to that type.
5970 This is a step towards IPv6 support.
5972 The silc_id_get_len takes now the ID as an extra argument.
5973 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5974 both IPv4 and IPv6 based ID's.
5976 The affected files are lib/silccore/id.[ch] and other files
5977 around the tree using these routines.
5979 * Removed the ID length arguments in server from various
5980 silc_server_send_notify_* routines -> they are not needed
5983 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5985 * Fixed memory leak in silc_encode_pem_file in the file
5986 lib/silcutil/silcutil.c.
5988 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5990 * Check minor version as well in the SKE. Affected files are
5991 silcd/protocol.c and lib/silcclient/protocol.c.
5993 * Added --identifier option to the server so that an identifier
5994 can be when creating the public key for the server. Affected
5995 file is silcd/silcd.c.
5997 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5998 lib/silccrypt/silcpkcs.c.
6000 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6002 * Register default ciphers and stuff when using -C option with
6003 the server. Affected file sildc/silcd.c.
6005 * Put back the servers public key filename format, it is better
6006 than the new one. For now, the client keys are saved with the
6007 new filename format. The affected file silc/client_ops.c.
6009 * Implemented the Cipher API for the rest of the ciphers that
6010 did not implement it or implemented it the wrong way.
6012 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6014 * Register default ciphers and stuff when using the -S option
6015 in the client. Affected file silc/silc.c. Same also when
6016 creating new key pair with -C option.
6018 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6020 * Fixed the silc_verify_public_key client operation function to
6021 save the public keys differently. The fingerprint is now
6022 used as filename and not the hostname. This way also the
6023 client keys are saved uniquely and not with hostnames. The
6024 affected file is silc/client_ops.c.
6026 * Trimmed the silc_hash_fingerprint function to remove extra
6027 whitespaces from the end of the fingerprint. The affected
6028 file is lib/silccrypt/silchash.c.
6032 * Added silc_cipher_register_default function to register all
6033 default ciphers. It can be used when configuration files
6034 does not exist and the application does not want any specific
6035 ciphers in any specific order.
6037 The SilcDList is now used as silc_cipher_list dynamically
6038 allocated cipher list. Removed the static list all together
6039 and now all ciphers must be allocated to the dynamic list.
6040 The silc_cipher_alloc routine was changed to check only the
6043 All silc_cipher_* routines that used to return int returns
6046 The affected files lib/silccrypt/silccrypt.[ch].
6048 * The same thing was done to silc_hash_* as for silc_cipher_*
6049 routines. Affected files lib/silccrypt/silchash.[ch].
6051 * The same thing was done to silc_pkcs_* as for silc_cipher_*
6052 routines. Affected files lib/silccrypt/silcpkcs.[ch].
6053 Added also silc_pkcs_[un]register[_default] functions.
6054 Removed the data_context from the PKCS API.
6056 * Added silc_hmac_register_default function to register default
6057 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
6058 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
6059 to unregister all hmacs at once.
6061 * Register the default ciphers, hash functions, PKCSs and HMACs
6062 if client's configuration file does not exist. The affected
6065 * The client did not load the hash functions from the SIM
6066 modules at all. Added support for this. Affected file is
6067 silc/clientconfig.c.
6069 * When decoding public key with silc_pkcs_public_key_decode, check
6070 the supported algorithm only if PKCS are registered. Affected
6071 file lib/silccrypt/silcpkcs.c. The same was done with the
6072 silc_pkcs_private_key_decode.
6074 * Fixed the SILC List routines to keep the list always in order.
6075 It used to change the list's order when traversing the list but
6076 not it preserves the order. Affected file lib/trq/silclist.h.
6078 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6080 * Added the client library to use the SilcSocketConnection's
6081 reference counter (by silc_socket_dup) to prevent the bug that
6082 the socket object may be freed underneath async operation.
6084 * The name resolv library checking fixes in the configure.in.pre.
6087 * Created new version of the protocol drafts for future
6088 development. The -03 drafts are the ones that will be changed
6089 in the trunk now and the -02 will remain as they are.
6091 * Send list of CUMODE notifys to the router when announcing
6092 the channel users to the router. Affected file silcd/server.c.
6093 If the router receiving channel founder CUMODE for a channel
6094 that already has channel founder it will send CUMODE notify
6095 to the sender to remove the channel founder rights from the
6096 announced client. Affected file silcd/packet_receive.c.
6098 * The CUMODE notify may now use Server ID as well as the entity
6099 who changes the mode. Updated protocool specs.
6101 * Updated INSTALL and README files.
6103 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6105 * New web pages in the http://silc.pspt.fi. The pages was
6110 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6112 * Implemented the [DenyConnectin] config section in the server.
6113 Added silc_server_config_denied_conn to check whether incoming
6114 connection is denied. Affected file silcd/serverconfig.[ch].
6116 * Do not check the ports when checking the incoming configuration
6117 data if the port is 0, meaning any. Affected file is
6118 silcd/serverconfig.c.
6120 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6122 * Fixed buffer overflow in silc_string_compare in the file
6123 lib/silcutil/silcutil.c.
6125 * Fixed double free in silc_server_command_leave in the file
6128 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6130 * Fixed the version checking in the server. Affected file is
6133 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6135 * Fixed the configuration data fetching when accepting new
6136 connections in the server. Affected file silcd/server.c.
6138 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6140 * Added `sender_entry' argument to the function
6141 silc_server_packet_relay_to_channel so that we can check
6142 whether some destination actually belongs to the same route
6143 the sender belongs (ie, we must not resend the packet to the
6144 sender). Affected file silcd/packet_send.[ch].
6146 * Added `servername' field to the SilcClientEntry in the server
6147 to hold the name of the server where client is from. Affected
6148 file is silcd/idlist.h.
6150 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6152 * Moved the channel message encrypting in the router betwen
6153 router connections from silc_server_channel_message to the
6154 silc_server_packet_relay_to_channel since we want to check
6155 whether we have anybody channel before encrypting anything.
6156 Affected files silcd/packet_[receive/send].c.
6158 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6160 * Fixed the [AdminConnection] server config section to support
6161 multiple entries. Affected file silcd/serverconfig.c.
6163 * Added support into the server to check the validity of the
6164 incoming connection before executing any KE or authentication
6167 * The connection configuration is now saved to the KE and
6168 connection auth protocol contexts and not fetched anymore in
6169 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
6171 * The local hosts listenning address and port is also resolved
6172 now when starting the server. We want to have the socket object
6173 to include the real address and port for the listener. Added
6174 new function silc_net_check_local_by_sock into the files
6175 lib/silcutil/silcnet.[ch].
6177 * Fixed a broadcast bug in server -> do not broadcast if we
6180 * Fixed a routing bug. Do not route broadcast packets ever.
6181 Broadcast packets must be processed always and not routed since
6182 they may be destined to some other host than yourself and thus
6183 would get routed without no good reason. Affected file is
6186 * Added function silc_server_config_is_primary_route to check
6187 whether primary router connection has been configured (a router
6188 configuration that we are initiating). If there is not, we
6189 will assume that there is only two routers in the SILC network
6190 and we will use the incoming router connection as our primary
6191 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
6193 * Changed the order of the broadcasting. Broadcast _after_ the
6194 packet has been processed not before. Affected file is
6197 * Fixed a [ClientConnection] parsing bug. The port was never
6198 parsed correctly thus resulting to port 0. Affected file
6199 silcd/serverconfig.c.
6201 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
6202 argument and did not set the broadcast packet flag. Affected
6203 file silcd/packet_send.c. Fixed same bug in the function
6204 silc_server_send_notify as well.
6206 * If we receive NEW_ID packet for our own ID in the server, ignore
6209 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6213 * Removed the nickname from the Private Message Payload.
6214 Updated the code and the protocol specs.
6216 * Updated protocol specs for submitting to the IETF.
6218 * Tweaked the Random Number Generator a bit. Affected file
6219 lib/silccrypt/silcrng.c. Exported a new function
6220 silc_rng_[global]_add_noise which can be used to add more
6223 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6225 * Do not parse packets with different timeout when protocol
6226 is active -> may cause problem with rekey. Affected file
6229 * When server receives signoff notify it must not create
6230 new channel key if the client is on any channels since the
6231 sender of the signoff notify will create it.
6233 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6235 * Added printing of error messages during SKE protocol from the
6236 failure packet sent by server during SKE. Affected file
6239 * Removed the client's failure_callback handling with timeout
6240 and handle it immediately when received.
6242 * The SKE library returned wrong type in SUCCESS and FAILURE
6243 packets. They must be 32 bit MSB not 16 bit MSB.
6245 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6247 * Ok, rewrote the logic of the re-key and now it seems to work.
6248 I tested it on high traffic with frequent re-keys without
6249 problems. Added hmac_receive (and renamed hmac to hmac_send)
6250 in SilcClientConnection in lib/silcclient/client.h and
6251 in SilcIDListData in silcd/idlist.h. Also, removed the
6252 SilcPacketParserContext's cipher and hmac fields as they are
6253 not needed anymore and actually caused some problems when
6254 the ciphers and hmac's changed underneath the packet parser.
6256 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6258 * If re-key protocol is active then process the incoming packets
6259 synchronously since we must assure that icoming packets encrypted
6260 with the old key is processed before the new keys is set to
6261 use. This is true other packets than for REKEY packets.
6262 Affected file silcd/server.c. The same was done to client library
6263 as well, affected file lib/silcclient/client.c.
6265 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6267 * Fixed bug in client and server to accept the force send if
6268 the packet is send from silc_[server/client]_packet_process
6269 function. Otherwise the packets are never delivered, oops.
6271 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6273 * Disable force sending of packets when REKEY protocol is active.
6274 We must assure that no packet is sent directly when rekey is
6275 performed. All packets must be sent through packet queue.
6276 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
6277 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
6278 function is silc_[server/client]_packet_send_real to check
6281 * Replaced the SIM paths from example config files to
6282 /usr/local/modules. Also, make install creates now
6283 /usr/local/silc/logs directory to hold all the SILC server
6286 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6288 * Made the configure.in.pre work on Solaris. Patch by salo.

6297 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6299 * When MAC computation fails the silc_packet_decrypt returned 0
6300 even though it was supposed to return -1. Fixed this. The
6301 affected file is lib/silccore/silcpacket.c.
6303 * Do not replace the config files in /etc/silc (in make install)
6304 if they already exist. Affected file ./Makefile.am.
6306 * Do not send re-key packets immediately but through packet queue.
6307 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6309 * Changed silc_net_check_host_by_sock to return FALSE if the
6310 IP/DNS could not be resolved. Though, it returns the IP address
6311 now even if it could not resolve it (but returns also FALSE).
6312 Affected file lib/silcutil/silcnet.[ch].
6314 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6316 * Added silc_pkcs_decode_identifier to decode the public key's
6317 identifier. Affected file lib/silccrypt/silpkcs.[ch].
6318 Added also silc_pkcs_free_identifier. Added also new context
6319 SilcPublicKeyIdentifier.
6321 * Added -S option to the silc client. It is used to dump the
6322 contents of the specified public key file.
6324 * Changed the PKCS api to return the public key length when
6325 setting the public key.
6327 * Fixed a fatal bug in the public and private key file loading.
6328 Affected file lib/silccrypt/silcpkcs.c.
6330 * Execute the packet parsing for client with zero (0) timeout
6331 if the protocol is active. Affected file silcd/server.c.
6333 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6335 * Made the key generation options to the silcd program. Added
6336 -C option, equivalent to client's option.
6338 * Added new [ServerKeys] config section to the server. It
6339 configures the server's public and private key.
6341 * Defined generic Public Key Payload into the protocol
6342 specification to send specific type of public keys and
6345 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6346 public key or certificate.
6348 * Implemented the GETKEY command to the server and to the
6349 client library and on user interface.
6351 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6353 * Made preliminary `make install' work.
6355 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6357 * Added SilcServerRekey context into silcd/idlist.h.
6359 * Added the PFS support as defined in the specification to the
6360 SKE protocol. Affected files lib/silcske/*.c.
6362 * Added `ske_group' field to the SilcServerRekey context to hold
6363 the number of the SKE group that is used with PFS in re-key.
6364 Affected file silcd/idlist.h.
6366 * Added PFS re-key support to the server. Affected file is
6369 * Added silc_protocol_cancel to cancel execution of the next
6370 state of the protocol. Affected file is
6371 lib/silccore/silcprotocol.[ch].
6373 * Added the re-key support with and without PFS to the client
6374 library. Re-key is performed once in an hour, by default.
6376 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6377 Added silc_client_rekey_callback and silc_client_rekey_final.
6378 Affected files are lib/silcclient/protocol.[ch] and
6379 lib/silcclient/client.[ch].
6381 * Removed the `hmac_key' and `hmac_key_len' fields from the
6382 SilcClientConnection structure; not needed. Affected file is
6383 lib/silcclient/client.h.
6387 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6389 * Do not ask whether user wants to use the negotiated private key
6390 for private messages, just use it. Affected file is
6391 silc/local_command.c.
6393 * Added `send_enc_key' and `enc_key_len' fields to the
6394 SilcIDListData structure since they are needed in the re-key
6395 phase. Affected file is silcd/idlist.[ch].
6397 * Implemented the simple re-key protocol into the server.
6398 Affected files silcd/server.c and silcd/protocol.[ch]. The
6399 re-key will be performed once in an hour, by default.
6401 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6402 Added silc_server_rekey, silc_server_rekey_callback and
6403 silc_server_rekey_final.
6405 * Removed Tunneled flag from the protocol. Updated the code
6406 and the specifications.
6408 * Adde `pfs' field to the SilcIDListData to indicate whether
6409 the PFS is to be performed in the re-key. Affected file is
6412 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6414 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6415 int64 of at least the xintXX size. If void * is less that 4
6416 bytes uint32 * will be used. Defined bool as boolean.
6418 * Changed _ALL_ unsigned long and unsigned int to uint32,
6419 unsgined short to uint16 in the source tree.
6421 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6422 not handle clients that has entry->data.registered == FALSE.
6423 They are not in the network anymore. Affected file is
6426 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6428 * Implemented the sending of the SERVER_SIGNOFF notify in the
6429 server. Affected file is silcd/server.c.
6431 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6432 Added also silc_notify_payload_encode_args into the
6433 lib/silccore/silcnotify.[ch].
6435 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6436 Affected file silcd/packet_receive.c.
6438 * Implemented the SERVER_SIGNOFF notify handling in the client
6439 library. Affected file lib/silcclient/client_notify.c. Also,
6440 implemnted the printing of the SERVER_SIGNOFF info to the
6441 application. Affected file silc/client_ops.c.
6443 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6444 if the deleting was successful. Affected file silcd/idlist.[ch].
6446 * Added support for public key authentication in the connection
6447 authentication protocol in the client library. Affected file
6448 lib/silcclient/protocol.c.
6450 * Changed the server's silc_idlist_get_clients_by_* interface
6451 to support already allocated array so that new entries may be
6452 added to pre-allocated array. Affected file silcd/idlist.[ch].
6453 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6454 and command replies.
6456 * All command reply functions in the server now calls the
6457 pending command callback even if error occured. This way the
6458 error will be delivered to the client as well. Affected files
6459 silcd/command.c and silcd/command_reply.c.
6461 * Fixed INFO command to return local server's info if no server
6462 was provided. Affected file lib/silcclient/command.c.
6464 * Removed RESTART command for good. Updated the code and the
6467 * Rewrote parts of the task system. It is a bit simpler now.
6468 Removed unsued task priorities. The affected files are
6469 lib/silcutil/silctask.[ch].
6471 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6473 * Moved the USERS printing from the library to the application.
6474 Affected files lib/silcclient/command.c and silc/client_ops.c.
6476 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6480 * Added channel key re-key support. The re-key is perfomed
6481 only by the router and is done once in an hour. Added `rekey'
6482 field to the SilcChannelEntry in the server. Affected files
6483 silcd/server.c and silcd/idlist.h.
6485 * Added silc_task_unregister_by_context into the file
6486 lib/silcutil/silctask.[ch].
6488 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6490 * Added SILC_UMODE_GONE mode to indicate when the client is not
6491 present in the SILC network. Added also support to the local
6492 command AWAY that will set this mode. Added support of showing
6493 "xxx is gone" in WHOIS command. The USERS command shows the
6494 gone status as well.
6496 * Fixed setting server and router operator privileges in the
6497 server's UMODE command. Affected file silcd/command.c.
6499 * Merged the SKE KE1 and KE2 payloads into one payload. The
6500 new KE payload is equivalent to the old KE2 payload.
6502 Cleaned up the SKE Start Payload parsing. It now uses the
6503 simple buffer unformatting to do the parsing. A lot faster
6506 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6507 to the SKE that is used to indicate whether both of the SKE
6508 parties should perform authentication. By default only the
6509 responder performs authentication. By setting this flag also
6510 the initiator must do authentication. By default it is unset
6511 since in normal SKE case, client to server connection, only
6512 the responder should do authentication. When doing SKE between
6513 two clients both should perform authentication. Updated the
6514 code and the protocol specs.
6516 * A little fix to IDENTIFY command in the server. Search the
6517 client first by hash not nickname. Affected file is
6520 * Fixed the silc_client_close_connection to support closing
6521 the client to client connections wihtout deleting too much
6522 data. Affected file lib/silcclient/client.c.
6524 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6525 are received if protocol used to be active but is not anymore
6526 the application would crash due to NULL pointer dereference.
6527 Affected files silcd/server.c and lib/silcclient/client.c.
6529 * Added `hash' field to the SilcClientConnection to include
6530 the hash function negotiated in the SKE protocol.
6532 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6533 to set the channel founder authentication data. A client can
6534 claim the founder rights later by providing the authentication
6535 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6536 This way the channel founder can regain the channel founder
6537 privileges even it is left the channel. This works only on
6538 local server and the client must be connected to the same
6539 server to be able to regain the founder rights. Updated the
6540 protocol specs accordingly.
6542 Added support to the CMODE command in the client to set the
6543 founder auth data. Read the README to see how to set it.
6545 Added support to the CUMODE command to claim the founder
6546 rights. Read the README to see how to do it.
6548 Added support for the founder authentication to the Channel
6549 Entry in the server. Affected file silcd/idlist.h.
6551 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6552 server's CMODE command. Affected file silcd/command.c.
6554 * Added the following new functions into lib/silccore/silcauth.[ch]:
6555 silc_auth_get_method and silc_auth_get_data.
6557 * The server now saves the remote hosts public key to the
6558 SilcIDListData pointer. Affected file silcd/protocol.c.
6560 * The normal server now does not remove the channel entry from
6561 the cache if the founder authentication data is set. It used
6562 to remove it if the founder was the last one on the channel on
6563 the server and left the channel. The auth data is saved and
6564 if the channel is re-joined later the old entry is used with
6565 the old auth data. Affected files silcd/command_reply.c and
6568 * Removed the `pkcs' field from the SilcIDListData structure
6569 in the server; it is not used. Affected file silcd/idlist.h.
6571 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6573 * Fixed packet processing on slow links. Partial packets were
6574 never re-processed because the incoming data buffer was cleared
6575 by the application. Application must not directly clear the
6576 sock->inbuf, the packet processing routines handle it. Fixed
6577 this in client library and in server.
6579 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6581 * Fixed the WHOIS and IDENTIFY send reply function to really
6582 check whether to send list or just one entry. Affected file
6585 * Cleaned up the LEAVE command's channel key distribution. The
6586 affected file silcd/command.c.
6588 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6589 can enforce the channel mode as well. In that case the ID
6590 includes the ID of the server. The code now enforces the
6591 mode change if the router have different mode than the server.
6593 * The notify client operation with CMODE_CHANGE notify can now
6594 return NULL client_entry pointer if the CMODE was not changed
6595 by client. Application must check for this.
6597 * Added <Server ID> argument to INFO command to support server
6598 info fetching by Server ID.
6600 * Added silc_server_announce_get_channel_users to get assembled
6601 packets of channel users of the specified channel. Affected
6602 file silcd/server.[ch].
6604 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6605 was freed underneath the ID Cache.
6607 * Re-announce clients when the server received CHANNEL_CHANGE
6608 notify from the router. Affected file silcd/packet_send.c.
6610 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6612 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6613 crashed since it did not handle the fact that there is no cipher
6614 called "3" and didn't check the error condition. Now fixed.
6616 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6617 flag. It can be used to send message requests.
6619 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6621 * Implemented the RESTART command in the client.
6623 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6624 notice type messages. Added notice printing to the user
6627 * The channel keys are not re-generated if the channel's mode
6628 is PRIVKEY, ie private key on the channel exists. Affected
6629 files silcd/server.c and silcd/command.c.
6631 * Fixed a little bug in channel message delivery when channel
6632 private keys are set in the server. Affected file is
6633 silcd/packet_send.c.
6635 * Changed the setting on channel->on_channel = TRUE from the
6636 silc_client_save_channel_key to the JOIN command reply. The
6637 key payload is not received if the private channel key is set.
6638 Affected file lib/silcclient/command_reply.c and the
6639 lib/silcclient/client_channel.c.
6641 * When the CMODE_CHANGE notify is sent and the channel private
6642 key mode is removed the channel key must be re-generated in
6643 other cells as well. Added this support for the router in the
6644 silcd/packet_receive.c.
6646 * Added new local command NOTICE to send notice message on
6647 channel. Affected file silc/local_command.[ch].
6649 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6651 * Added new local command ME to the client. It is used to send
6652 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6653 some action. Affected file silc/local_command.[ch].
6655 * Changed channel_message and private_message client operations
6656 to deliver the message flags to the application. Added also
6657 the `flags' arguments to the silc_client_send_channel_message
6658 and silc_client_send_private_message functions. Affected file
6661 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6663 * Redefined the Private Message Payload to support private message
6664 keys and to support the new private message flags. Updated
6665 the protocol specs. Flags makes it possible to have for example
6666 CTCP style messages.
6668 * Added new type SilcPrivateMessagePayload and defined an API
6669 for it in the lib/silcclient/silcprivate.[ch].
6671 * Tested private message private keys successfully. Tested the
6672 private message key set, unset and list commands with the new
6675 * Redefined the Channel Message Payload to include the channel
6676 message flags (equal with private message flags) to support
6677 for example CTCP style messages.
6679 * Defined some of the message (for channel and private message)
6680 flags. Updated the protocol specs and added the flags to the
6681 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6683 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6685 * Added SilcKeyAgreementStatus type to the key agreement routines
6686 to indicate the current status and error if one occured.
6687 The status types are defined in the lib/silcclient/silcapi.h.
6689 * Added new local command KEY that is used to set and unset private
6690 keys for channels, set and unset private keys for private messages
6691 with remote clients and to send key agreement requests and
6692 negotiate the key agreement protocol with remote client. The
6693 key agreement is supported only to negotiate private message keys,
6694 it currently cannot be used to negotiate private keys for channels,
6695 as it is not convenient for that purpose.
6697 * Fixed a minor pending callback setting bug in the function
6698 silc_client_get_client_by_id_resolve, now the function works.
6699 Affected file lib/silcclient/idlist.c.
6701 * Added function silc_net_get_local_port to get local bound
6702 port by socket. Added to lib/silcutil/silcnet.[ch].
6704 * Added `sockets' and `sockets_count' fields to the SilcClient
6705 object. They hold the sockets of the listenning sockets in
6706 the client. Listenning sockets may be for example the key
6707 agreement server. Affected file lib/silcclient/client.[ch].
6708 Added functions the silc_client_add_socket and the
6709 silc_client_del_socket. They are exported to the application
6712 * Added ~./silc/clientkeys to support other client's public keys.
6714 * Renamed verify_server_key client operation to verify_public_key
6715 and added one argument to indicate the type of the connection
6716 (server, client etc.).
6718 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6720 * Added silc_server_connection_auth_request to handle the
6721 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6722 silcd/packet_receive.[ch].
6724 * Added silc_server_send_connection_auth_request into the
6725 silcd/packet_send.c to send the connection auth request packet.
6727 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6730 * Fixed the public key authentication in responder side in the
6731 server. The `auth_data' pointer includes the SilcPublicKey
6732 not the path to the public key. Affected file silcd/protocol.c.
6734 * Implemented the public key authentication in the initiator side
6735 in the server. Affected file silcd/protocol.c.
6737 * Removed the [RedirectClient] config section from the server
6738 configuration. Is not needed and I don't want to implement it.
6740 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6742 * Cleaned up the CMODE command in the server. It now works
6743 correctly and supports all the modes defined in the protocol.
6744 Affected file is silcd/command.c.
6746 * Added `hmac_name' field to the SilcChannelEntry in the server
6747 to hold the default HMAC of the channel. It can be set when
6748 creating the channel (with JOIN command). Affected files
6751 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6752 type to indicate the change of the current cipher and hmac
6753 on the channel. Client can safely ignore the <cipher> argument
6754 (if it chooses to do so) since the CHANNEL_KEY packet will
6755 force the channel key change anyway. The <hmac> argument is
6756 important since the client is responsible of setting the new
6757 HMAC and the hmac key into use.
6759 * Fixed the CMODE command in the client library as well.
6761 * Tested CMODE command in router environment successfully.
6763 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6765 * Show the version of the remote client (or server) when connecting
6766 to the server. It is logged to the log file. Affected file
6767 is silcd/protocol.c.
6769 * Fixed the KILLED notify handling in the client library. The
6770 client must be removed from all channels when receiving the
6773 Also, do not remove the client entry when giving the KILL
6774 command but when the KILLED notify is received.
6776 * Removed silc_idlist_find_client_by_nickname from the server.
6777 Not needed anymore. Affected files silcd/idlist.[ch].
6779 * Implemented the CHANNEL_CHANGE notify type handling to the
6780 server. Affected file silcd/server.c.
6784 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6786 * Added silc_server_send_notify_invite to send the INVITE
6787 notify between routers.
6789 * Implemented the INVITE command correctly to the server.
6791 * Implemented the INVITE notify type handling in the server.
6793 * Implemented the INVITE command to the client library and on the
6796 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6798 * Added function silc_server_get_client_resolve to find the
6799 client entry by ID from all ID lists and then resolve it
6800 (using WHOIS) if it cannot be found. Affected file is
6803 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6805 * Implemented the BAN command to the client library.
6807 * The JOIN command in the server now checks the invite list
6810 * Changed the silc_command_reply_payload_encode_va and the
6811 silc_command_payload_encode_va to support that if argument is
6812 NULL it ignores and checks the next argument. Affected file
6813 lib/silccore/silccommand.c.
6815 * Added silc_server_send_notify_ban to send the BAN notify
6816 type between routers.
6818 * Chaned the silc_notify_payload_encode to support that if
6819 argument is NULL it ignores and checks the next argument.
6820 Affected file lib/silccore/silcnotify.c.
6822 * Tested ban lists in router environment successfully.
6824 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6826 * Implemented BAN command to the server, in silcd/command.[ch].
6828 * Removed the BAN and INVITE_LIST modes from the CMODE command
6831 * Added function silc_string_match to regex match two strings.
6832 Affected files lib/silcutil/silcutil.[ch].
6834 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6836 * Redefined parts of the SilcChannelEntry in the server to support
6837 the new ban and invite lists.
6839 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6841 * Redefined the INVITE command. The same command can be used to
6842 invite individuals to the channel but also to manage the invite
6843 list of the channel (to add to and remove from the invite list).
6844 Updated the protocol specs.
6846 * Added new command SILC_COMMAND_BAN that can be used to manage
6847 the ban list of the channel. Updated the protocol specs.
6849 * Removed the channel modes: the SILC_CMODE_BAN and the
6850 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6851 in the CMODE command. The equivalent features are now available
6852 using INVITE and BAN commands. Updated the protocol specs.
6854 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6855 in the network about change in the current ban list. The notify
6856 type is not used by the client.
6858 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6859 support the invite lists.
6861 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6863 * Added new function silc_string_regexify that converts string
6864 including wildcard characters into regex string that can
6865 be used by the GNU regex library. Added into the file
6866 lib/silcutil/silcutil.[ch].
6868 Added silc_string_regex_combine to combine to regex strings
6869 into one so that they can be used as one regex string by
6870 the GNU regex library. Added into the file
6871 lib/silcutil/silcutil.[ch].
6873 Added silc_string_regex_match to match two strings. It returns
6874 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6876 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6878 * Imported GNU regex to the soruce tree into lib/contrib.
6879 Fixed some compiler warning from the regex.c.
6881 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6883 * Fixed MOTD command in the server to work in router environment.
6885 * Fixed the MOTD command in the client library to support
6886 the server argument in the command.
6888 * Added `nickname_len' argument to the silc_idlist_add_client
6889 in the server, as the `nickname' argument may be binary data
6892 * Added silc_idlist_get_channels to return all channels from
6895 * Implemented LIST command to the server. Affected file is
6898 * Implemented the LIST command to the client library and on the
6901 * Added [<user count>] argument to the LIST command reply.
6902 With private channels the user count is not shown.
6904 * Updated TODO and README.
6906 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6908 * The client entry's data.registered must be TRUE even with
6909 global client entry on global client list. The data.registered
6910 is used to check whether the client is anymore in the network,
6911 for example with WHOWAS command so it must be valid.
6913 * Fixed the WHOWAS command in the server. It now actually works
6914 in router environment. Added function into silcd/command_reply.c
6915 silc_server_command_reply_whowas_save.
6917 * Added silc_idlist_purge function to the silcd/idlist.c
6918 to periodically purge the ID Cache.
6920 * Fixed INFO command in the server. It works now in router
6921 environment. Added <server name> argument to the INFO command
6922 reply. Updated the protocol specs.
6924 * Fixed minor bug in silc_idcache_purge to not purge if the
6925 expire value is zero.
6927 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6928 they were buggy because of the WHOWAS information.
6930 * Fixed local command MSG to handle the async resolving of
6931 the remote client properly. It used to fail the first MSG.
6932 Affected file silc/local_command.c.
6934 * Added `data_len' field to SilcIDCache context.
6936 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6938 * Update TODO. Todo in commands in the server.
6940 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6942 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6943 used by routers as broadcast packet to inform other routers
6944 about the changed user mode.
6946 Implemented the notify handling in the server. Affected file is
6947 silcd/packet_receive.c. Added the function
6948 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6950 * Added new generic Channel Payload and deprecated the New Channel
6951 Payload. The New Channel Payload is now the generic Channel
6954 * Added new argument `mode' to the silc_server_send_new_channel
6955 as it is required in the Channel Payload now.
6957 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6958 and created a new and real SilChannelPayload to represent the
6959 new generic Channel Payload. Implemented the encode/decode
6960 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6962 * Added silc_server_get_client_channel_list to return the list
6963 of channels the client has joined for WHOIS command reply.
6964 Affected file silcd/server.[ch].
6966 * Implemented the channel list sending in the WHOIS command reply
6967 in server and in the client.
6969 Implemented the channel list displaying on the user interface
6970 as well. Affected file silc/client_ops.c.
6972 * Added silc_channel_payload_parse_list to parse list of Channel
6973 Payloads. It returns SilcDList list of SilcChannelPayloads.
6974 Client for example can use this function to parse the list of
6975 channels it receives in the WHOIS command reply. The caller
6976 must free the list by calling silc_channel_payload_list_free.
6977 Affected files lib/silccore/silcchannel.[ch].
6979 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6981 * Added one new argument <user mode> to the WHOIS command reply
6982 to return the mode of the user in SILC. Updated the protocol
6985 Implemented it to the server and client.
6987 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6989 * Fixed the mode printing on the user interface on joining.
6990 Affected file silc/client_ops.c.
6992 * Implemented the UMODE command and user modes in general to the
6993 client library and to the user interface.
6995 * Implemented the UMODE command to the server.
6997 * The server now sends UNKNOWN_COMMAND error status if client sends
6998 unknown command. Affected file silcd/command.c.
7000 * All server commands now handle the command identifier the right
7001 way when sending the command reply to the client. The client can
7002 use to identify the command replies with the identifier.
7004 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7006 * Added silc_server_get_client_route to resolve the route to
7007 the client indicated by the client ID. Affected file is
7010 * Added silc_server_relay_packet as general function to relay
7011 packet to arbitrary destination. This deprecates functions
7012 like _send_private_message_key, _relay_notify etc. Affected
7013 file is silcd/packet_send.[ch].
7015 Removed silc_server_send_key_agreement,
7016 silc_server_send_private_message_key and
7017 silc_server_packet_relay_notify functions from the file
7018 silcd/packet_send.[ch].
7022 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
7023 server. Affected file silcd/packet_receive.[ch].
7025 * Implemented the KILL command to the client. Implemented the
7026 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
7027 Affected files lib/silcclient/command[_reply].c and
7028 lib/silcclient/client_notify.c. Implemented the KILL notify
7029 printing in the user inteface.
7031 * Fixed a lot silc_parse_nick memory leaks from the client
7032 library in the file lib/silcclient/command.c.
7034 * Changed the silc_server_send_notify_on_channels's `sender'
7035 argument from SilcSocketConnection to SilcClientEntry to
7036 check the sender as entry and not as connection object and not
7037 to send to the client provided as argument. The affected file
7038 is silcd/packet_send.[ch].
7040 * The notify packets that are destined directly to the client used
7041 to not to be processed by the server. Now changed that and the
7042 server processes all notify packets. After relaying the packet
7043 to the client the notify packet is processed in the server.
7045 * The silc_server_free_client_data now checks whether there is
7046 pending outgoing traffic for the client and purges the data to
7047 the network before removing the client entry.
7049 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7051 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
7052 an client is killed from the SILC Network. Updated the protocol
7055 Added new function silc_server_send_notify_killed to the
7056 silcd/packet_send.[ch].
7058 * Added function silc_server_packet_relay_notify to relay notify
7059 packets that are destined directly to a client. In this case
7060 the server does not process the notify packets but merely relays
7061 it to the client. Affected file silcd/packet_send.[ch].
7063 Added also silc_server_packet_process_relay_notify to check
7064 whereto relay the notify. Affected file is
7065 silcd/packet_receive.[ch].
7067 * Implemented the KILL command to the server.
7071 * Added the backup schema desgined last fall to the protocol
7072 specs for everyone to see. The specification is in the
7073 *-spec-xx.txt draft and the packet type definitions for the
7074 backup routers is in *-pp-xx.txt draft. Thusly, added also
7075 new packet type SILC_PACKET_CELL_ROUTERS.
7077 * A big security problem in the implementation discovered. The
7078 signoff of an client did not cause new channel key generation
7079 which it of course should've done. The channel keys must be
7080 always re-generated when client leaves (or signoffs) the channel.
7081 The silc_server_remove_from_channels funtion now handles
7082 the channel key re-generation.
7084 * Added `sender' argument to the silc_server_send_notify_on_channels
7085 to not to send the client provided as argument. Affected file
7086 silcd/packet_send.[ch].
7088 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7090 * Implemented OPER and SILCOPER commands into the server and
7093 * Added silc_auth_verify and silc_auth_verify_data to verify
7094 the authentication directly from the authentication payload.
7095 It supports verifying both passphrase and public key based
7096 authentication. Affected file lib/silccore/silcauth.[ch].
7098 * Added `hash' field to the SilcIDListData structure. It is the
7099 hash negotiated in the SKE protocol. Affected file is
7102 * Slight redesigning of the SilcAuthPayload handling routines.
7103 Do not send SilcPKCS but SilcPublicKey as argument.
7105 * Implemented the public key authentication support to the
7106 serverconfig. The public key is loaded from the provided path
7107 and saved as authentication data to void * pointer. Thus,
7108 changed the unsigned char *auth_data to void *auth_data;
7110 * Fixed SHUTDOWN command to send the reply before the server
7111 is shutdown. :) Affected file silcd/command.c.
7113 * Fixed fatal bug in CONNECT command. The hostname was invalid
7114 memory and server crashed. Affected file silcd/command.c.
7116 * Fixed fatal bug in CLOSE command. The server_entry became
7117 invalid but was referenced later in the command. Affected file
7120 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7122 * Fixed fatal bug in failure packet handling. Server ignored
7123 the failure and thus crashed when it came.
7127 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7129 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
7130 that the command may be executed only once in (about) 2 seconds.
7131 The old SILC_CF_LAG flag is same but allows command bursts up
7132 to five before limiting.
7134 Added the support for CF_LAG and CF_LAG_STRICT flags to the
7135 server code. Various commands now includes the CF_LAG_STRICT
7136 flag to disallow any kind of miss-use of the command.
7138 * Fixed the silc_buffer_unformat to not to allocate any data
7139 if the length of the data is zero. It used to allocate the
7140 length + 1. Affected file lib/silcutil/silcbuffmt.c.
7142 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7144 * Changed the format of AdminConnection configuration section
7145 in the server. Added username of the admin to the format.
7146 Affected files silcd/serverconfig.[ch].
7148 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
7149 to return admin configuration data by host, username and/or
7152 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7154 * Implemented WHOWAS command to the server. Added the functions:
7156 silc_server_command_whowas_parse,
7157 silc_server_command_whowas_send_reply,
7158 silc_server_command_whowas_from_client and
7159 silc_server_command_whowas_from_server
7161 * Added <Client ID> argument to the WHOWAS command reply. Updated
7162 the protocol specs accordingly.
7164 * Implemented WHOWAS command and command_reply to the client
7167 Implemented the WHOWAS printing on the user interface.
7169 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7171 * Added new argument to the WHOWAS command reply, the real name.
7172 It is an optional argument. Updated the protocol specs.
7174 * Added SilcIDCacheDestructor callback that is registered when
7175 the SilcIDCache is allocated. The callback is called when
7176 an cache entry in the ID Cache expires, or is purged from the
7177 cache. Added into lib/silccore/idcache.[ch].
7179 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
7180 to destruct the client entries when the cache entry expires.
7181 Other ID Cache's in server and in the client library ignores
7184 * If the ID Cache entry's `expire' field is zero then the entry
7185 never expires. Added boolean `expire' argument to the
7186 silc_idcache_add function in the lib/silccore/idcache.[ch].
7187 If it is TRUE the default expiry value is used.
7189 * Added silc_server_free_client_data_timeout that is registered
7190 when client disconnects. By default for 5 minutes we preserve
7191 the client entry for history - for WHOWAS command.
7193 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7195 * Added support to the server to enforce that commands are not
7196 executed more than once in 2 seconds. If server receives
7197 commands from client more frequently, timeout is registered
7198 to process the commands. Affected file silcd/command.c.
7199 Added new function silc_server_command_process_timeout.
7201 * Changed NICK_NOTIFY handling in client library to check that
7202 if the client's nickname was changed, so there is no need to
7203 resolve anything from the server.
7205 * Removed error printing from the WHOIS and IDENTIFY commands.
7206 If error occurs then it is ignored silently in the client library.
7207 The application, however, may map the received error to
7208 human readable error string. The application currently maps
7209 the NO_SUCH_NICKNAME error to string.
7211 * Made the command status message public to the application. Moved
7212 them from lib/silcclient/command_reply.c to
7213 lib/silcclient/command_reply.h. The application can map the
7214 received command status to the string with the
7215 silc_client_command_status_message function.
7217 * Added check to the server to check that client's ID is same
7218 as the Source ID in the packet the client sent. They must
7221 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7223 * Added dist-bzip hook to the Makefile.am to make bzip2
7224 compressed distributions.
7226 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7228 * Server now enforces the maximum length for the nickname and
7229 the channel as protocol specification dictates. 128 bytes for
7230 nickname and 256 bytes for channel name.
7232 * Moved the WHOIS printing to the application. The client libary
7233 does not print out the WHOIS information anymore, the application
7234 must do it. Renamed silc_client_command_reply_whois_print to
7235 the silc_client_command_reply_whois_save.
7237 The client's idle time is also sent to the application now, and
7238 the idle is shown on screen.
7240 * Added silc_client_command_reply_identify_save to save the
7241 received IDENTIFY entries.
7243 * Do not check for channel private keys in message sending and
7244 reception if the channel does not have the PRIVKEY mode set.
7245 Affected file lib/silclient/client_channel.c.
7247 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7249 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
7250 just surfaced after chaning the JOIN procedure.
7252 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7254 * Added silc_client_get_clients_by_list to get client entries
7255 from Client ID list, that is returned for example by JOIN
7256 and USERS command replies. The application should use this
7257 function for example when JOIN command reply is received to
7258 resolve the clients already on the channel (library does not
7259 do that anymore as USERS command reply is not used in the JOIN
7260 procedure anymore). Affected files lib/silcclient/silcapi.h and
7261 lib/silcclient/idlist.c.
7263 * JOIN command reply and USERS command reply returns now SilcBuffer
7264 pointers instead of unsigned char pointers when returning
7265 the client list and mode list.
7267 * Added <Client ID> argument to the JOIN command reply, mainly
7268 for the server to identify for which client the command was
7269 originally sent. Updated protocol specs accordingly.
7271 * Added SilcDlist private_key pointer to the SilcChannelEntry
7272 in the client to support the channel private keys. Affected
7273 file is lib/silcclient/idlist.h.
7275 * Added SilcChannelPrivateKey argument to the function
7276 silc_client_send_channel_message so that application can choose
7277 to use specific private ke if it wants to. If it is not provided,
7278 the normal channel key is used, unless private keys are set.
7279 In this case the first (key that was added first) is used
7280 as the encryption key.
7282 * Implemented the support for channel private key handling.
7283 Implemented the following functions:
7285 silc_client_add_channel_private_key,
7286 silc_client_del_channel_private_keys,
7287 silc_client_del_channel_private_key,
7288 silc_client_list_channel_private_keys and
7289 silc_client_free_channel_private_keys
7291 Affected file lib/silcclient/client_channel.c.
7293 * Added the support for the private keys in the channel message
7294 sending and encryption and in the message reception and
7295 decryption. Affected funtions are
7296 silc_client_send_channel_message and silc_client_channel_message.
7298 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7300 * Added SKE's key verify callback to the client library's
7301 KE protocol context. Affected files lib/silcclient/protocol.[ch].
7303 * Removed the statement that server (or router) must send USERS
7304 command reply when joining to the channel so that the client
7305 knows who are on the channel. Instead, the client list and
7306 client's mode list is now sent in the JOIN command reply to the
7307 client who joined channel. This is better solution.
7309 * Added function silc_server_get_users_on_channel and function
7310 silc_server_save_users_on_channel to the silcd/server.[ch].
7312 * Removed function silc_server_command_send_users from the
7315 * Do not show topic on the client library anymore. The topic is
7316 sent in the command reply notify to the application and the
7317 application must show the topic now.
7319 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7321 * Added client searching by nickname hash into the IDENTIFY and
7322 WHOIS commands in the server as they were clearly missing from
7323 them. Affected file is silcd/command.c.
7325 * Fixed a bug in private message receiving in the client library.
7326 The remote ID was freed and it wasn't supposed, now it is
7329 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7331 * Minor fix to the channel payload; allocate the data area, as it
7332 needs to be of specific length.
7334 * If the key agreement port is zero then the operating
7335 system will define the bound port. Affected files are
7336 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7338 * Added new function silc_channel_payload_decrypt into the file
7339 lib/silccore/silcchannel.[ch].
7341 * Moved the channel message etc, check from silc_packet_decrypt
7342 to applications. The library calls now a generic
7343 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7344 when the packet is either normal or special. This was done to
7345 allow more wide range of checking that was not allowed when
7346 the code was in library. Now applications can do virtually any
7347 checks to the packet and return to the library the decision how
7348 the packet should be processed. Affected files are
7349 lib/silccore/silcpacket.[ch].
7351 Added silc_server_packet_decrypt_check to the server and
7352 silc_client_packet_decrypt_check to the client library.
7354 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7355 to send with specified source and destination information.
7357 * Channel message delivery between routers was broken after the
7358 channel key distribution was fixed earlier. The channel key
7359 was used be to distributed to other routers as well which is not
7360 allowed by the protocol. Now this is fixed and channel keys
7361 really are cell specific and the channel message delivery between
7362 routers comply with the protocol specification.
7364 * Fixed various commands in server to check also the global list
7365 for the channel entry and not just the local list. The affected
7366 file silcd/command.c.
7368 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7370 * Added assert()s to buffer formatting and unformatting routines
7371 to assert (if --enable-debug) when error occurs. Affected
7372 file: lib/silcutil/silcbuffmt.c.
7374 * Changed to auto-reconnect to check whether the remote host is
7375 router and register the re-connect timeout if it is. It used
7376 to check that whether we are normal server, but router must do
7377 auto-reconnect with another router as well. Affected file
7380 * Removed the [<key len>] option from CMODE command as the cipher
7381 name decides the key length, nowadays. See the defined ciphers
7382 from the protocol specification.
7384 * Added [<hmac>] option to the CMODE command to define the HMAC
7385 for the channel. Added SILC_CMODE_HMAC channel mode.
7387 * Added [<hmac>] option for the JOIN command so that user can
7388 select which HMAC is used to compute the MACs of the channel
7391 * Added Hmac field to the Channel Message Payload. The integrity
7392 of plaintext channel messages are now protected by computing
7393 MAC of the message and attaching the MAC to the payload. The
7394 MAC is encrypted. Now, it is clear that this causes some
7395 overhead to the size of the packet but rationale for this is that
7396 now the receiver can verify whether the channel message decrypted
7397 correctly and also when private keys are set for the channel the
7398 receiver can decrypt the packet with several keys and check from
7399 the MAC which key decrypted the message correctly.
7401 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7402 lib/silccrypt/silccipher.[ch].
7404 * Added silc_hash_len to return the digest length into the
7405 lib/silcrypt/silchash.[ch].
7407 * Rewrote parts of Silc Channel Payload interface in the
7408 lib/silccore/silcchannel.[ch]. The encode function now also
7409 encrypts the packet and parse function decrypts it.
7411 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7413 * Fixed a minor formatting bug in the SKE's key material processing.
7414 It actually might have processed the keys wrong way resulting
7417 * Redefined the mandatory HMAC algorithms and added new algorithms.
7418 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7419 and hmac-md5 truncated to 96 bits. The mandatory is now
7420 hmac-sha1-96. Rest are optional (including the one that used
7421 to be mandatory). Rationale for this is that the truncated HMAC
7422 length is sufficient from security point of view and can actually
7423 make the attack against the HMAC harder. Also, the truncated
7424 HMAC causes less overhead to the packets. See the RFC2104 for
7427 * Added new [hmac] configuration section. The SKE used to use
7428 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7429 is of course wrong. The official names that must be proposed in
7430 the SKE are the ones defined in the protocol specification
7431 (hmac-sha1-96 for example). The user can configure any hmac
7432 using any hash function configured in the [hash] section. At
7433 least, the mandatory must be configured.
7435 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7437 * Added HMAC list to the SKE proposal list. It has now both
7438 hash algorithm list and HMAC list. This makes the protocol
7439 incompatible with previous versions. The SKE now seems to work
7440 the way it is supposed to work, for the first time actually.
7442 * Defined plain Hash algorithms to the protocol specification.
7445 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7447 * Implemented support for key agreement packets into the server.
7448 Added functions silc_server_key_agreement and
7449 silc_server_send_key_agreement. Other than these functions,
7450 server has nothing to do with this packet.
7452 * Added support for private message key packets into the server.
7453 Added functions silc_server_private_message_key and
7454 silc_server_send_private_message_key.
7458 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7459 called in the protocol's final callback instead in the END
7460 protocol state. This makes a little more sense and in the same
7461 time in client we can use the same protocol routines for normal
7462 key exchange and to key agreement packet handling as well.
7464 * Added to both client's and server's KE protocol context the
7465 SilcSKEKeyMaterial pointer to save the key material. We will
7466 bring the key material to the protocol's final callback by doing
7467 this. The final callback must free the key material.
7469 * Added SKE's packet_send callback into client's KE protocol
7470 context so that the caller can choose what packet sending function
7471 is used. This way we can use different packet sending when
7472 doing normal SKE when doing key agreement packet handling (in
7473 the key agreement packet handling we do not want to encrypt
7476 * Implemented the responder side of the key agreement routines
7477 in the client. The client can now bind to specified port and
7478 accept incoming key negotiation. The key material is passed
7479 to the application after the protocol is over.
7481 * Implemented the processing of incoming Key Agreement packet
7482 in the client. Added function silc_client_key_agreement to
7485 * Implemented the intiator side of the key agreement routines
7486 in the client. The client can now initiate key agreement with
7487 another remote client. The key material is passed to the
7488 application after the protocol is over.
7490 * Created client_keyagr.c to include all the key agreement
7493 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7494 SILC_TASK_CALLBACK except that it is not static.
7496 * Created client_notify.c and moved the Notify packet handling
7497 from the client.[ch] into that file.
7499 * Created client_prvmsg.c and moved all private message and
7500 private message key routines from the client.[ch] into that file.
7502 * Create client_channel.c and moved all channel message and
7503 channel private key routines from the client.[ch] into that file.
7505 * Changed silc_client_get_client_by_id_resolve to resolve with
7506 WHOIS command instead of IDENTIFY command, in the file
7507 lib/silclient/idlist.c.
7509 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7511 * Implemented the SKE's responder side to the Client library.
7513 * When FAILURE is received to the protocol do not trust it
7514 blindly. Register a timeout to wait whether the remote closes
7515 the connection as it should do it, only after that process the
7516 actual failure. This was changed to both client and server.
7518 * Added client_internal.h to include some of the structures
7519 there instead of client.h in lib/silcclient/.
7521 * Added function silc_task_unregister_by_callback to unregister
7522 timeouts by the callback function.
7524 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7526 * Some "Incomplete WHOIS info" errors has been appearing on the
7527 log files. Took away the entry->userinfo check from WHOIS
7528 reply sending. The entry->userinfo is now " " if client did not
7529 provide one. I thought this was fixed earlier but something
7530 is wrong still. Let's see if the error still appears.
7532 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7534 * Fixed a minor bug in the login when the channel key is
7535 re-generated in the server. It used to generate the key in
7536 wrong order and thus caused problems in the channel traffic.
7538 * Fixed a minor bug in channel key distsribution after
7539 KICK command. The key was not sent to the router even though
7542 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7544 * Added silc_ske_process_key_material_data as generic routine
7545 to process any key material as the SILC protocol dictates. The
7546 function is used by the actual SKE library but can be used by
7547 applications as well. This relates to the private message keys
7548 and the channel private keys since they must be processed the
7549 same way the normal SILC session keys. The protocol dictates
7550 this. Affected files: lib/silcske/silcske.[ch].
7552 Added also silc_ske_free_key_material to free the
7553 SilcSKEKeyMaterial structure.
7555 * Defined silc_cipher_set_key function to set the key for
7556 cipher without using the object's method function. The affected
7557 files: lib/silccrypt/silccipher.[ch].
7559 * Implemented silc silc_client_add_private_message_key,
7560 silc_client_add_private_message_key_ske,
7561 silc_client_del_private_message_key,
7562 silc_client_list_private_message_keys and
7563 silc_client_free_private_message_keys functions in the
7566 Added functions silc_client_send_private_message_key to send
7567 the Private Message Key payload and silc_client_private_message_key
7568 to handle incoming Private Message Key payload.
7570 * Added Cipher field to the Private Message Key payload to set
7571 the cipher to be used. If ignored, the default cipher defined
7572 in the SILC protocol (aes-256-cbc) is used.
7574 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7576 * Removed lib/silcclient/ops.h file.
7578 Redefined parts of the SILC Client Library API. Created new
7579 file silcapi.h that deprecates the ops.h file and defines the
7580 published Client Library API. Defined also private message key
7581 API and channel private key API into the file.
7583 This is the file that the application must include from the
7584 SILC Client Library. Other files need not be included by
7585 the application anymore.
7587 * Added new key_agreement client operation callback and also
7588 defined the Key Agreement library API for the application.
7590 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7592 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7593 is used by clients to request key negotiation between another
7594 client in the SILC network. If the negotiation is started it
7595 is performed using the SKE protocol. The result of the
7596 negotiation, the secret key material, can be used for example
7597 as private message key.
7599 Implemented the Key Agreement payload into the files
7600 lib/silccore/silauth.[ch].
7602 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7604 * Redefined ciphers for the SILC protocol. Added some new ciphers
7605 and defined the key lengths for the algorithms. Changed the
7606 code accordingly. The default key length is now 256 bits.
7608 * Fixed SKE key distribution function silc_ske_process_key_material
7609 when the key length is more than 128 bits. The default key
7610 length in SILC is now 256 bits.
7612 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7613 to indicate unsupported algorithm.
7615 * Renamed rijndael.c to aes.c and all functions as well.
7617 * Fixed a long standing channel key setting bug in client library.
7618 Weird that it has never surfaced before.
7620 * Fixed bug in channel deletion. If the entire channel is removed
7621 then it must also delete the references of the channel entry
7622 from the client's channel list as the client's channel entry and
7623 the channel's client entry share same memory.
7625 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7627 * Implemented CONNECT and SHUTDOWN commands in the client.
7629 * Implemented CLOSE command to the client.
7631 * Added the function silc_idlist_find_server_by_name into the
7632 files silcd/idlist.[ch].
7634 Added the function silc_idlist_find_server_by_conn into the
7635 files silcd/idlist.[ch].
7637 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7639 * DIE command was renamed to SHUTDOWN. Updated the both code
7642 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7643 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7645 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7648 * Added function silc_server_create_connection function to create
7649 connection to remote router. My server implementation actually
7650 does not allow router to connect to normal server (it expects
7651 that normal server always initiates the connection to the router)
7652 so the CONNECT command is only good for connecting to another
7655 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7657 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7658 or some other client was kicked from the channel.
7660 Implemented the handling of the notify type to both client
7663 Implemented silc_server_send_notify_kicked to send the KICKED
7664 notify. It is used to send it to the server's primary router.
7666 * Implemented the KICK command into server and client.
7668 * Added `query' argument to the silc_idlist_get_client function
7669 to indicate whether to query the client from server or not if
7672 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7673 to indicate that the client is not channel founder.
7677 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7679 * Removed the rng context from SilcPacketContext structure and
7680 changed that the packet routine uses the Global RNG API.
7682 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7684 * Added support for quit message that client can "leave" on the
7685 channel when it quits the SILC. It is ditributed inside the
7686 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7688 Added silc_server_free_client_data that will take the
7689 signoff message as argument.
7691 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7693 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7695 * Updated parts of the protocol specification to keep it up
7698 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7700 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7701 payloads in one packet.
7703 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7704 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7705 use now the new List flag.
7707 * Also deprecated the following packet types: REPLACE_ID,
7708 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7710 * Added list support for Notify packet in server.
7712 * Added silc_server_send_notify_channel_change to send the
7713 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7714 the silc_server_send_replace_id.
7716 * Added silc_server_send_notify_nick_change to send the
7717 NICK_CHANGE notify type. Deprecates the function
7718 silc_server_send_replace_id.
7720 * Added silc_server_send_notify_join to send the JOIN notify type.
7721 Deprecates the function silc_server_send_new_channel_user.
7723 * Added silc_server_send_notify_leave to send LEAVE notify type.
7724 Deprecates the function silc_server_send_remove_channel_user.
7726 * Added silc_server_send_notify_cmode and
7727 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7728 types. Deprecates the silc_server_send_set_mode function.
7730 * Added SERVER_SIGNOFF notify type to indicate that server has
7731 quit. This means that all clients on the channel from that
7732 server will drop. This can be also used when netsplit happens.
7734 Deprecated REMOVE_ID packet type since it is not needed anymore
7737 Added silc_server_send_notify_server_signoff to send the
7738 SERVER_SIGNOFF notify type. Deprecates the function
7739 silc_server_send_remove_id.
7741 Added also silc_server_send_notify_signoff to send the
7742 SIGNOFF notify type.
7744 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7745 SILC protocol from this day on. Changed the protocol
7746 specification as well.
7748 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7749 notify type. It is used between routers to notify about
7750 topic changes on a channel.
7752 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7755 * Partly updated the protocol specification to comply with the
7756 changes now made. It is still though a bit outdated.
7758 * The JOIN notify type now takes one extra argument <Channel ID>.
7759 The packet used to be destined to the channel but now the
7760 JOIN type may be sent as list thus it is impossible to
7761 destine it to any specific channel. By adding this argument
7762 it is again possible.
7764 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7766 * Added CREDITS file. The CHANGES and CREDITS file will appear
7767 in the distribution as well.
7769 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7771 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7772 types in the server's silcd/packet_receive.c.
7774 * Implemented CMODE and CUMODE to work in router environment.
7776 * Fixed minor encoding and decoding buglet from the
7777 lib/silccore/silcmode.c.
7779 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7782 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7784 * Changed all SilcConfigServer* and silc_config_server* to
7785 SilcServerConfig* and silc_server_config*, respectively.
7788 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7790 * Associated the ID (client or server ID) to the Authentication
7791 Payload to avoid any possibility of forging. Updated the
7792 protocol specification and the code accordingly.
7794 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7796 * The RSA key length is now save to the RsaKey context in the
7797 key generation process in lib/silccrypt/rsa.c. The key length
7798 is now used to figure out the maximum size of the block allowed
7799 to be encrypted/signed.
7801 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7802 is equivalent to the silc_mp_mp2bin but does not allocate any
7805 * Changed silc_mp_mp2bin API to take length argument. If it is
7806 non-zero then the buffer is allocated that large. If zero, then
7807 the size is approximated using silc_mp_sizeinbase, which however
7810 * Created Global RNG API which is global RNG that application can
7811 initialize. After initializing, any routine anywhere in the
7812 code (including library) can use RNG without allocating a new
7813 RNG object. This was done to allow this sort of use of the
7814 RNG in code that has no chance to allocate RNG object. All
7815 applications currently allocate this and many routines in the
7816 library use this. Affected file lib/silccrypt/silcrng.[ch].
7818 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7819 it to use the Global RNG API.
7821 * Defined Authentication Payload into protocol specification that
7822 is used during SILC session to authenticate entities. It is
7823 used for example by client to authenticate itself to the server
7824 to obtain server operator privileges.
7826 Implemented this payload into the lib/silccore/silcauth.[ch].
7827 Implemented also routines for public key based authentication
7828 as the new protocol specification dictates.
7830 Moved definitions of different authentication methods from
7831 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7833 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7834 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7835 silc_pkcs_verify_with_hash functions into the file
7836 lib/silccrypt/silcpkcs.[ch].
7838 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7840 * The client entry's userinfo pointer must be always valid.
7841 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7842 will fail since it requires the userinfo. Now, the userinfo
7843 is allocated as "" if actual userinfo does not exist. Actually,
7844 it must exist and it is totally Ok to drop client connections
7845 that does not announce the userinfo. However, we will make
7846 this workaround for now.
7848 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7849 to return the remote port by socket.
7851 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7853 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7854 SILC_SERVER_PENDING_EXEC and added an new macro
7855 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7856 data or when error occurs while processing the pending command.
7858 Added new argument `destructor' into silc_server_command_pending
7859 and to the SilcServerCommandPending object. This destructor is
7860 now called after calling the pending callback or if error occurs
7861 immediately. If error occurs the actual pending callback won't
7862 be called at all - only the destructor. The destructor may be
7863 NULL if destructor is not needed.
7865 All this applies for client library code as well. Similar
7866 changes were made there as well for the pending commands.
7868 In the client, the application must now allocate the
7869 SilcClientCommandContext with the silc_client_command_alloc
7872 * Added reference counter to the SilcServerCommandContext. Added
7873 function silc_server_command_alloc and silc_server_command_dup
7876 Same type of functions added to the client library for the same
7879 * Removed the cmd_ident from IDListData away since it is now
7880 global for all connections. It is the command identifier used
7881 in command sending and with pending commands. The affected file
7884 * Added reference counter to the SilcSocketConnection objecet to
7885 indicate the usage count of the object. The object won't be
7886 freed untill the reference counter hits zero. Currently only
7887 server uses this, and client ignores it. The client must be
7888 set to use this too later. The affected files are
7889 lib/silccore/silcsockconn.[ch]. Added also the function
7890 silc_socket_dup to increase the reference counter.
7892 This was mainly added because it is possible that the socket
7893 is removed underneath of pending command or other async
7894 operation. Now it won't be free'd and proper DISCONNECTING
7895 flags, etc. can be set to avoid sending data to connection that
7896 is not valid anymore.
7898 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7899 the connection. After that it sets SILC_SET_DISCONNECTED.
7900 It is, however, possible that the socket data is not still freed.
7901 The silc_server_packet_process now checks that data is not
7902 read or written to connection that is DISCONNECTED. The socket
7903 get's freed when the reference counter hits zero.
7905 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7907 * Changed the client operation API: channel_message operation's
7908 `sender' is now the client entry of the sender, not the nickname
7909 and the `channel' is the channel entry, not the channel name.
7911 In the private_message operation the `sender' is now also the
7912 client entry of the sender not the nickname.
7914 Affected file is lib/silcclient/ops.h and all applications
7915 using the client operations.
7917 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7919 * Moved the calling of ops->connect() from connect_to_server_final
7920 into receive_new_id functin since that is the point when the
7921 client is actually allowed to send traffic to network. The
7922 affected file is lib/silcclient/client.c.
7924 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7926 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7927 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7928 (if needs broadcasting) instead of broadcasting the packets one
7929 by one which would make a burst in the network traffic.
7931 * Added `broadcast' argument to the functions in silcd/server.[ch]
7932 silc_server_create_new_channel[_with_id] to indicate whether
7933 to send New Channel packet to primary router.
7935 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7937 * Added new function into the silcd/server.[ch] files:
7938 silc_server_create_new_channel_with_id to create new channel with
7939 already existing Channel ID.
7941 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7942 lib/silccore/silcpacket.h. This packet is used t send list of
7943 Set Mode payloads inside one packet. Server uses this to set
7944 the modes for the channels and clients on those channels, that it
7945 announced to the router when it connected to it. The protocol
7946 specification has been updated accordingly.
7948 * The silc_server_new_channel did not handle the packet coming
7949 from normal server as it normally does not send that. However,
7950 when it announces its channels it does send it. Implemented
7951 the support for that.
7953 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7954 into the file lib/silccore/id.h.
7956 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7958 * Fixed memory leaks in the functions silc_idlist_del_client,
7959 silc_idlist_del_channel and silc_idlist_del_server in the file
7960 silcd/idlist.c. All of those leaked like a sieve.
7962 * Fixed some small memory leaks in the client's function
7963 silc_client_notify_by_server.
7965 * Added functions into silcd/server.c: silc_server_announce_clients,
7966 silc_server_announce_channels and silc_server_announce_server.
7967 These functions are used by normal and router server to announce
7968 to its primary router about clients, channels and servers (when
7969 router) that we own. This is done after we've connected to the
7972 These functions effectively implements the following packet types:
7973 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7974 and SILC_PACKET_NEW_ID_LIST.
7976 * Added new functions into the silcd/packet_receive.[ch]:
7977 silc_server_new_id_list, silc_server_new_channel_list and
7978 silc_server_new_channel_user_list to handle the incoming
7979 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7981 * Added support of changing Channel ID in the function
7982 silc_server_replace_id. If the server that announces a channel
7983 to the router already exists in the router (with same name but
7984 with different Channel ID), router is responsible to send
7985 Replace ID packet to the server and force the server to change
7986 the Channel ID to the one router has.
7988 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7989 client that the Channel ID has been changed by the router. The
7990 normal server sends this to the client. Client must start using
7991 the new Channel ID as the channel's ID.
7993 Implemented handling of this new type into lib/silcclient/client.c
7994 into the function silc_client_notify_by_server.
7996 * Added new function silc_idlist_replace_channel_id into the files
7997 silcd/idlist.[ch] to replace the Channel ID.
7999 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8001 * Call silc_server_command_identify_check always when processing
8002 the IDENTIFY command in silcd/command.c
8004 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8006 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
8007 send keepalive packets. The packet can be sent by clients,
8008 servers and routers.
8010 Added function silc_socket_set_heartbeat into the file
8011 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
8012 If not set, the heartbeat is not performed. The actual
8013 heartbeat is implemented in the low level socket connection
8014 library. However, application is responsible of actually
8017 Added silc_server_send_heartbeat to send the actual heartbeat
8018 packet into silcd/packet_send.[ch]. Server now performs
8019 keepalive with all connections.
8021 * Added silc_task_get_first function into lib/silcutil/silctask.c
8022 to return the timeout task with shortest timeout. There was a bug
8023 in task unregistration that caused problems. TODO has been
8024 updated to include that task system must be rewritten.
8026 * The client library will now resolve the client information when
8027 receiving JOIN notify from server for client that we know but
8028 have incomplete information.
8030 * Rewrote parts of silc_server_remove_from_channels and
8031 silc_server_remove_from_one_channel as they did not remove the
8032 channel in some circumstances even though they should've.
8034 * Encryption problem encountered in server:
8036 The LEAVE command used to send the Channel Key packet to the
8037 router immediately after generating it. However, the code
8038 had earlier sent Remove Channel user packet but not immediately,
8039 ie. it was put to queue. The order of packets in the router
8040 was that Channel Key packet was first and Remove Channel User
8041 packet was second, even though they were encrypted in the
8042 reverse order. For this reason, MAC check failed. Now, this
8043 is fixed by not sending the Channel Key packet immediately but
8044 putting it to queue. However, this is more fundamental problem:
8045 packets that are in queue should actually not be encrypted
8046 because packets that are sent immediately gets encrypted
8047 actually with wrong IV (and thus MAC check fails). So, packets
8048 that are in queue should be encrypted when they are sent to
8049 the wire and not when they put to the queue.
8051 However, the problem is that the current system has not been
8052 designed to work that way. Instead, the packet is encrypted
8053 as soon as possible and left to the queue. The queue is then
8054 just purged into wire. There won't be any fixes for this
8055 any time soon. So, the current semantic for packet sending
8058 o If you send packet to remote host and do not force the send
8059 (the packet will be in queue) then all subsequent packets to the
8060 same remote host must also be put to the queue. Only after the
8061 queue has been purged is it safe again to force the packet
8064 o If you send all packets immediately then it safe to send
8065 any of subsequent packets through the queue, however, after
8066 the first packet is put to queue then any subsequent packets
8067 must also be put to the queue.
8069 Follow these rules and everything works fine.
8071 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8073 * Added new function silc_server_remove_clients_by_server to
8074 remove all client entries from ID list when the server connection
8075 is lost. In this case it is also important to invalidate all
8076 client entires as they hold the invalid server entry. This
8077 fixes fatal bug when server has lost connection and will reconnect
8080 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8082 * Made some sanity checks to silc_server_daemonise like to check
8083 whether the requested user and group actually exists.
8085 * Added sanity check to SKE's silc_ske_responder_finish to check
8086 that the public and private key actually is valid.
8088 * Invalidate the client's nickname when receiving Replace ID
8089 packet and the Client ID is being replaced. This means that the
8090 server will query the nickname if someone needs it (client)
8093 * Sort the ID Cache in client library when the ID Cache data
8094 has changed (needs sorting).
8096 * Do not allow for SILC client to create several connections to
8097 several servers. The client does not support windows right now
8098 and generating multiple connections causes weird behaviour.
8100 Irssi-silc client does support windows and can handle several
8101 connections without problems, see: www.irssi.org and SILC plugin.
8103 * Fixed some places where client was added to the IDList. The
8104 rule of thumb is following (in order to get everything right):
8105 If the client is directly connected local client then the
8106 `connection' argument must be set and `router' argument must be
8107 NULL to silc_idlist_add_client function. If the client is not
8108 directly connected client then the `router' argument must
8109 bet set and the `connection' argument must be NULL to the
8110 silc_idlist_add_client function.
8112 * The funtion silc_server_packet_send_local_channel actually did
8113 not check whether the client was locally connected or not. It
8114 does that now. Fixed a bug related to LEAVE command.
8116 * Fixed Remove Channel User payload parsing bug in server's
8117 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
8119 * The server's silc_server_save_channel_key now checks also the
8120 global ID list for the channel as it might not be in the local
8121 list. Fixed a bug related to LEAVE command.
8123 * Is this the end of the [<unknown>] buglet that has been lurking
8124 around for a long time? A little for loop fix in server's
8125 silc_server_command_whois_parse that is used by both IDENTIFY
8126 and WHOIS command. At least, this was a clear bug and a cause
8127 of one type of [<unknown>] buglet.
8129 * WHOIS and IDENTIFY commands call the function
8130 silc_server_command_[whois/identify]_check function even if
8131 we are not router server.
8133 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8135 * Added --with-gmp configuration option. If set the GMP
8136 is always compiled in the SILC source tree. If not set then
8137 it is checked whether the system has the GMP3 installed. If
8138 it has then the GMP won't be compiled (the system's headers
8139 and library is used), if it doesn't have it then the GMP is
8140 compiled in the SILC source tree.
8142 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8144 * Changed RSA private exponent generation to what PKCS #1
8145 suggests. We try to find the smallest possible d by doing
8146 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
8147 not security fix but optimization.
8149 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8151 * Added new config entry [Identity] to fork the server and run
8152 it as specific user and group. A patch from Bostik.
8154 * Imported Dotconf configuration library into lib/dotconf.
8155 This will be used to create the SILC configuration files later.
8156 It will appear in the distsribution after this commit.
8158 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8160 * A big code auditing weekend happening. Auditing code for
8161 obvious mistakes, bugs and errors. Also, removing any code
8164 Removed files for being obsolete:
8166 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
8167 inline in the file lib/silcutil/silcbuffer.h)
8169 o lib/silcutil/silcbufutil.c (the header has inline versions)
8171 Changed code to fix possible error conditions:
8173 o The buffer formatting routines now check that the destination
8174 buffer really has enough space to add the data. This applies for
8175 both buffer formatting and unformatting
8176 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
8177 unformatting was changed to accomodate following rules:
8178 XXX_*STRING_ALLOC will allocate space for the data into the pointer
8179 sent to the function while XXX_*STRING will not allocate or copy
8180 the data into the buffer. Instead it sets the pointer from the
8181 buffer into the pointer sent as argument (XXX_*STRING used to
8182 require that the pointer must be allocated already). This change
8183 makes this whole thing a bit more consistent and more optimized
8184 (note that the data returned in the unformatting with XXX_*STRING
8185 must not be freed now). The routines return now -1 on error.
8187 o Tried to find all code that use buffer_format and buffer_unformat
8188 and added return value checking to prevent formatting and
8189 especially unformatting errors and possible subsequent fatal
8192 o Changed ske->x and ske->KEY to mallocated pointers in
8193 lib/silcske/silcske.h. Fixed possible data and memory leak.
8195 o Added return value checking to all *_parse* functions. Fixed
8196 many memory leaks as well.
8198 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
8199 so that buffer overflows would not happen. All code now also
8200 checks the return value as it can fail.
8202 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8204 * Added reconnection support to server if the normal server looses
8205 its connection to the router (for example if router is rebooted).
8206 The server performs normal reconnection strategy implemented
8207 to the server. Affected file silcd/server.c.
8209 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8211 * Added new packet type SILC_PACKET_SET_MODE that is used to
8212 distribute the information about changed modes (for clients,
8213 channels and clients channel modes) to all routers in the
8214 network. Updated the protocol specification accordingly.
8216 Added functions into silcd/packet_send.c and
8217 silcd/packet_receive.c: silc_server_send_set_mode,
8218 silc_server_set_mode.
8220 Added new files silcmode.[ch] into lib/silccore that implements
8221 the encoding and decoding of Set Mode Payload. Added new type
8222 SilcSetModePayload. Moved the definitions of different modes
8223 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
8225 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8227 * Oops, a little mistake in server's connection authentication
8228 protocol. The protocol is not ended with FAILURE but with
8229 SUCCESS if the authentication is Ok. :) Affected file is
8232 * Implemented NICK_CHANGE notify handling in server in the file
8233 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
8234 the local clients on the channel. After the changing nickname
8235 in router environment snhould work and the [<unknown>] nickname
8236 should appear no more.
8238 The silc_server_replace_id function that receives the Replace ID
8239 payload now sends the NICK_CHANGE notify type also in the file
8240 silcd/packet_receive.c
8242 * Changed WHOIS and IDENTIFY command to support the maximum amount
8243 of arguments defined in protocol specs (3328 arguments). This
8244 fixed a bug that caused problems when there were more than three
8247 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8249 * Added extra parameter, command identifier, to the
8250 silc_client_send_command so that explicit command identifier
8253 Changed that ID list routines uses specific command identifier
8254 when sending WHOIS/IDENTIFY requests to the server so that they
8255 can be identified when the reply comes back.
8257 Affected files lib/silcclient/command.[ch],
8258 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
8260 * Added `sender' argument to silc_server_packet_send_to_channel
8261 to indicaet the sender who originally sent the packet to us
8262 that we are now re-sending. Ignored if NULL. Affected file
8263 silcd/packet_send.[ch].
8265 * Added some server statistics support in silcd/server_internal.h
8266 SilcServerStatistics structure and around the server code. Also
8267 send some nice statistics information when client is connecting
8270 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8272 * Fixed channel ID decoding in server's JOIN command reply in
8273 silcd/command_reply.c
8275 * Fixed braodcasting of replace ID payload to not to send it if
8276 we are standalone server in silcd/packet_receive.c.
8278 * Fixed all channel message sending routines to not to send
8279 packets to clients that has router set, since they are routed
8280 separately in the same function earlier. Affects file
8281 silcd/packet_send.c and all channel packet sending functions.
8283 * In USERS reply, res_argv[i] are not allocated, the table
8284 is allocated. Thus changed that free the table, not its
8287 * In server's whois_check and identify_check if the client is
8288 locally connected do not send any WHOIS commands - they are not
8291 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8293 * Fixed some minor bugs in client when sending WHOIS command. The
8294 arguments was in wrong order.
8296 * Removed statis function add_to_channel from server in
8297 silcd/command.c that was previously used with the joining but
8300 * Tested USERS command in router environment successfully with two
8301 routers, two servers and two clients.
8303 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8305 * Reorganized the USERS command and command reply in client library
8306 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
8307 When the command is given by user we register a pending command
8308 callback that will reprocess the command after the reply has been
8309 received from the server. When reprocessing the packet we then
8310 display the information. Thus, the USERS information is displayed
8311 now in the command callback instead of in the command reply
8312 callback. The processing of the command is same as previously
8313 when server has sent the command reply in the JOINing process.
8315 * Added to USERS command in silcd/command_reply.c to join the client,
8316 we didn't use to know about, to the channel after we've created
8317 a client entry for it. Also, for clienet we did know already still
8318 check whether it is on the channel or not and add it if not.
8320 * Removed silc_server_command_join_notify as the function and its
8323 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8325 * Changed the client's pending command handling to the same as the
8326 server's pending command handling. It is also now possible to
8327 execute command reply functions from other command reply
8328 function as the function callbacks for commands and command
8329 replies are one and same. The pending commands are not static
8330 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8331 in client connection context. Thus, pending commands are server
8332 connection specific as it is convenient.
8334 Changed the function silc_client_command_pending and
8335 silc_client_command_pending_del and added new function
8336 silc_client_command_pending_check. Removed the
8337 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8340 * Added cmd_ident, current command identifier, to the client
8341 connection context in lib/silcclient/client.h to keep track on
8342 command identifiers used in command sending. Client's command reply
8343 function handling now supports the mandatory command identifiers.
8345 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8346 funtions in client to fully support pending command callbacks.
8348 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8349 as one of the arguments to the application in the command reply
8352 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8353 before first releasing SILC but came back. Now it is removed again
8354 and should come back nomore. The FORWARDED flag was used only
8355 by the JOINing procedure by forwarding the command packet to router.
8356 Now, the JOINing procedure has been changed to more generic (due
8357 to various router environment issues) and FORWARDED is not needed
8358 anymore for anything. The protocol specification is yet to be
8361 Now, removed silc_server_packet_forward from server and the flag
8362 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8364 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8366 * Renamed NAMES command to USERS command. The NAMES was named that
8367 due to historical reasons. Now it is renamed. Also, rewrote
8368 parts of the USERS command. The nickname list is not sent anymore
8369 by the server. Only Client ID and mode lists are sent in the USERS
8370 command. Changed this also to the protocol specification.
8372 The client now resolves the names and stuff after it receives
8373 the USERS list from the server when joining to the channel.
8375 * WHOIS and IDENTIFY commands has been changed to support multiple
8376 Client ID's per command. One can now search for multiple users
8377 in the network by sending only one WHOIS or IDENTIFY command.
8378 Changed the code and the protocol specifications.
8380 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8381 uses silc_server_command_whois_parse to parse the request. */
8383 * If normal server, do not parse the WHOIS and IDENTIFY requests
8384 before sending it to the router. Saves some time.
8386 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8388 * Fixed JOIN command on client library. Wrong number of arguments
8389 used to crash the client.
8391 * Added silc_server_channel_has_global function to check whether
8392 channel has global users or not.
8394 * Added silc_server_channel_has_local function to check whether channel
8395 has locally connected clients on the channel.
8397 * The silc_server_remove_from_one_channel now checks whether the
8398 channel has global users or not after given client was removed from
8399 the channel. It also checks whether the channel has local clients
8400 on the channel anymore. If it does not have then the channel entry
8401 is removed as it is not needed anymore.
8403 * The silc_server_notify now checks on JOIN notify whether the joining
8404 client is one of locally connected or global. If it is global then
8405 the channel has now global users on the channel and that is marked
8406 to the channel entry. Also, it now saves the global client to
8407 global list who is joining and JOINs it to the channel. This is
8408 for normal server, that is.
8410 Changed silc_server_send_notify_on_channel,
8411 silc_server_packet_relay_to_channel and
8412 silc_server_packet_send_to_channel check if we are normal server
8413 and client has router set (ie. global client) do not send the
8414 message to that client, as it is already routed to our router.
8416 * Implemented LEAVE notify type handling in silc_server_notify
8419 * Tested LEAVE command in router environment successfully. Tested
8420 with two routers, two servers and two clients.
8424 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8426 * Implemented SIGNOFF notify type handling in silc_server_notify
8429 * silc_server_remove_id now removes the client entry from all channels
8430 it has joined and thusly sends SIGNOFF notify type.
8432 * Rewrote the NAMES list generation in server by removing two excess
8433 loops. The lists are created now inside one loop.
8435 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8437 * silc_server_remove_channel_user checks now also global list
8438 for channel and client.
8440 * silc_server_new_channel_user checks now both local and global
8441 list for channel and client. Fixed a bug in client id decoding.
8442 Used to decode wrong buffer.
8444 * silc_server_channel_message checks now both local and global
8445 list for channel entry.
8447 * Tested channel joining (hence JOIN) in router environment
8448 successfully. Tested with two routers, two servers and two
8451 * Tested channel message sending in router environment successfully.
8453 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8455 * Added silc_server_save_channel_key into server.[ch] to save the
8456 received channel key in Channel Key payload processing. It is
8457 also used in JOIN command reply handling.
8459 Equivalent function silc_client_save_channel_key added into
8460 client.[ch] into client library.
8462 * Changed JOIN command reply to send information whether the channel
8463 was created or not (is existing already) and the channel key
8464 payload. Changed protocol specs accordingly.
8466 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8467 the request was sent by ID and not by nickname. Crashed on
8470 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8472 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8473 now correctly save the received data.
8475 * silc_server_free_sock_user_data now notifies routers in the
8476 network about entities leaving the network.
8478 At the same time implemented functions silc_server_remove_id
8479 and silc_server_send_remove_id to receive and send REMOVE_ID
8480 packets. The packet is used to notify routers in the network
8481 about leaving entities. The ID removed will become invalid in
8484 * Added function silc_idlist_del_server into server. Removes and
8485 free's server entry from ID list.
8487 * silc_server_private_message function now checks, if we are router,
8488 that the destination ID really is valid ID, naturally.
8490 * In router when NEW_ID packet is received (for new client) the
8491 hash of the Client ID is saved in the ID Cache but the
8492 client->nickname is set to NULL, instead of putting the hash
8495 IDENTIFY command now also checks that client->nickname must be
8496 valid. If it is not if will request the data from the server who
8497 owns the client. Added new function
8498 silc_server_command_identify_check.
8500 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8501 to set the command to already allocated Command Payload.
8503 * Tested private message sending in router environment with two
8504 routers, two servers and two clients. Fixed minor bugs and now
8507 * Fixed segfault from client's NAMES command. Used to crash if
8510 * Forwarded packets must not be routed even if it is not destined
8511 to the receiver. Changed server code comply with this.
8513 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8515 * Added `require_reverse_mapping' boolean value to ServerParams
8516 structure. If TRUE (not default) the server will require that
8517 the connecting host has fully qualified domain name.
8519 If the reverse mapping is not required and hostname could not be
8520 found the IP address is used as hostname.
8522 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8524 * Implemented version string checking to both client and server.
8525 The check is incomplete currently due to the abnormal version
8526 strings used in development version of SILC.
8528 * Changed all command functions in server to use the new
8531 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8533 * Changed char *data to unsigned char *data in ID Cache system to
8534 support binary data as ID Cache data. Changed code to support
8535 binary data in lib/silccore/idcache.c.
8537 * Renamed silc_server_packet_relay_command_reply to
8538 silc_server_command_reply as it is normal packet receiving
8539 function. Rewrote the function to accept command replys for
8540 servers and not only for clients.
8542 * Mark remote router always as registered server if we are connecting
8543 to it. Otherwise, commands sent by the router to us are ignored.
8545 * All ID List find routines now returns the ID Cache Entry pointer
8546 as well if requested.
8548 * WHOIS command works now in router environment, tested with two
8549 routers, two servers and two clients.
8551 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8552 in router environment (as it is almost equivalent to WHOIS) but
8553 hasn't been tested thoroughly. Added new functions:
8555 silc_server_command_identify_parse
8556 silc_server_command_identify_send_reply
8557 silc_server_command_identify_from_client
8558 silc_server_command_identify_from_server
8560 * Disabled route cache adding because adding two different ID's with
8561 same IP replaces the old cache entry thus giving wrong route.
8562 The entry->router->connection is always the fastest route anyway
8563 so route cache may not be needed. Of course, new routes maybe
8564 established after receiving the ID when the entry->router->connection
8565 might not be anymore the most optimal.
8567 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8569 * Add route cache for received ID for fast routing.
8571 * Added silc_server_packet_route to route received packet on router
8572 that is not destined to us.
8574 * Renamed silc_server_get_route to silc_server_route_get.
8576 * Added id_string and id_string_len fields into SilcServer to
8577 include encoded ServerID for fast comparing without excess
8578 encoding of the ID's.
8580 * Cleaned up WHOIS command on server side. Added following static
8583 silc_server_command_whois_parse
8584 silc_server_command_whois_check
8585 silc_server_command_whois_send_reply
8586 silc_server_command_whois_from_client
8587 silc_server_command_whois_from_server
8589 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8590 arguments in command replies. All command functions should be
8591 updated to use this macro.
8593 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8595 * Minor typo fixes on command reply handling on server.
8597 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8599 * Added silc_server_command_add_to_channel internal routine to add
8600 the client to the channel after router has created the channel and
8601 sent command reply to the server.
8603 * Added generic silc_server_send_command to send any command from
8606 * Use static buffer with ID rendering instead of duplicating data.
8608 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8610 * Fixed a channel user mode bug when joining to a channel server gave
8611 everybody channel founder rights, oops.
8613 * We mark ourselves as the router of the incoming server connection
8614 if we are router ourselves. This way we can check in some packet
8615 sending functions whether it is locally connected server. For
8616 incoming router connections we put NULL.
8618 * For router sending packets locally means now always sending the
8619 packet cell wide; to local clients and local servers. For normal
8620 server sending packet locally means sending it to only local
8623 * Fixed the JOIN command to really work in router environment. If the
8624 channel is created it is always created by the router. Router is
8625 also responsible of making the initial joining to the channel,
8626 sending JOIN notify to the sending server and distributing
8627 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8628 does not exist server doesn't do anything else but forward the
8629 command to the router which performs everything.
8631 * Added silc_server_send_channel_key function to send the Channel Key
8634 * Added silc_server_create_channel_key to create new channel key. The
8635 channel key is now re-generated everytime someone joins or leaves
8636 a channel, as protocol dictates. Note: channel->key_len is the
8639 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8641 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8642 packet_receive.[ch] to separate packet sending and receiving
8643 routines. The server.[ch] now includes everything else including
8644 actual packet processing (writing and reading data) and other
8647 Renamed silc_server_private_message_send_internal to
8648 silc_server_send_private_message. The routine is still though
8649 used only to relay private messages as server does not send
8650 private messages itself.
8652 Renamed silc_server_new_channel to silc_server_create_new_channel
8653 and added new function sicl_server_new_channel that handles the
8654 incoming New Channel packet. Added also new sending function
8655 silc_server_send_new_channel to send New Channel Payload.
8657 * Added new function silc_server_notify to process incoming notify
8658 packet to the server/router. Server may then relay the notify
8659 to clients if needed.
8661 * Added new function silc_server_new_channel_user to process incoming
8662 New Channel User packet. Router will redistribute the packet and
8663 send JOIN notify to its local clients and locally connected servers
8664 if needed. Normal server will send JOIN notify to its local client
8665 on same channel when received this packet. Added also corresponding
8666 sending function silc_server_send_new_channel_user to sent the
8669 * Added boolean route argument to send_notif_to_channel and
8670 packet_send_to_channel functions to attempt to route the packet
8671 if it is TRUE and send only locally if it is FALSE.
8673 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8675 * silc_server_replace_id now broadcasts the received replace ID
8676 packet if it is not broadcast packet already. The router must
8677 broadcast to inform other routers about changed ID.
8679 * Added backpointer to server's router into SilcServer context in
8680 silcd/server_internal.h.
8682 * Fixed silc_server_packet_broadcast to send correct broadcast
8685 * The channel key is now distributed to the local client as soon
8686 as it is received from the router (in router environment) so that
8687 no other packet may be sent for the channel until client has
8690 * silc_server_remove_channel_user now broadcasts the received
8691 Remove Channel User packet if it is not broadcast packet already.
8692 The router must broadcast to inform other routers about removed
8695 * Added users field into SilcPacketContext that is a reference count
8696 of the context. One can increase the reference count by calling
8697 silc_packet_context_dup which is now changed to just increase the
8698 reference count instead of duplicating the data. The reference
8699 count is decresed by calling silc_packet_context_free that will
8700 free the data after the reference count hits zero.
8702 For now on the packet context and everything allocated into it
8703 (including the raw packet from network) must be freed by calling
8704 the new silc_packet_context_free function. Added also new function
8705 silc_packet_context_alloc that must be used now to allocate the
8706 context. This also means that if a routine is asynchronous from
8707 silc_[client/server]_packet_parse_type the packet context must
8708 be duplicated by calling silc_packet_context_dup. Otherwise it
8709 gets free'd after silc_[client/server]_packet_parse_type returns.
8710 Also, one must remember that if packet is duplicated then its
8711 reference count must be decresed by calling the free function as
8712 many times as it was duplicated.
8714 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8715 from both client and server.
8717 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8719 * Made joining to a channel working in router environment.
8721 * Cleaned up JOIN command on server side and create function
8722 silc_server_command_join_channel internal routine to make the
8725 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8727 * Changed silc_command_pending list to SilcDList. Also, added
8728 `ident' field to SilcServerCommandPending structure to identify
8729 the reply and to call correct callback.
8731 Added silc_server_command_pending_check function to replace the
8732 corresnponding macro. The silc_command_pending list is not
8735 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8736 to set identifier to previously allocated Command Payload. It
8737 is used to set identifier for command when resending Command
8740 * Added silc_command_payload_encode_payload to encode Command
8741 Payload buffer from SilcCommandPayload structure.
8743 * Added silc_argument_payload_encode_payload to encode Argument
8744 payload buffer from SilcArgumentPayload structure.
8746 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8748 * Changed WHOIS command to support router connection on server side.
8749 The whois request is always sent to router unless the server is
8750 standalone server. After server has received the reply from the
8751 router will it send the reply to the client.
8753 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8754 broadcast received broadcast packet. The function is used only
8755 by router. The broadcast packet is always sent to the router's
8758 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8759 render given ID to printable string, for log files for example.
8761 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8763 * Made basic router to router connections working. At least they
8764 can now connect to each other but nothing really works the way
8765 they are supposed - yet.
8767 * Added new initiator token to RouterConnection configuration
8768 file in silcd/serverconfig.[ch]. It is used to tell whether we
8769 are the initiator to the remote router or whether we'll expect
8770 the other end to connect.
8772 * Moved registering of listener task to silc_server_init, hence
8773 the server starts listenning as soon as it is run, even if it
8774 does not have connections to other routers. Let's see how well
8777 * Changed default connection retry timeouts for more suitable in
8780 * Removed cipher and such arguments from silc_idlist_add_client
8781 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8782 Added new function silc_idlist_add_data to add the keys and stuff
8785 * Added SilcIDListData structure and added it to SilcClientEntry
8786 and SilcServerEntry as their first field in the structure. This
8787 way we can explicitly cast the ID entries to the SilcIDListData
8788 structure and get common data for the entries. In past, we had
8789 to first check what type of connection it is and then cast it to
8790 correct ID entry type. Now, we can directly cast the opaque
8791 pointer to the SilcIDListData (no matter what ID entry it actually
8792 is) and get the data needed.
8794 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8796 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8797 in some circumstances even if threre were timeout tasks, though not
8798 IO tasks, but tasks anyway. Now fixed.
8800 * Defined SilcServerConnection structure to hold connection specific
8801 stuff about directly connected servers and routers. The definition
8802 is currently in silcd/server_internal.h. I thought about having
8803 a bit more important role fro this struct but for now it is used
8804 only when connecting to other server (or router actually).
8806 * Added connecting retry support in server when connecting to
8807 router(s). The retry feature implement exponential backoff
8808 algorithm. Also, added SilcServerParams structure to hold default
8809 parameters for server. For now, it include these retry settings
8810 and are hard coded. After server is moded to be as Silc Server
8811 Library this structure will be more important.
8813 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8815 * Changed client librarys channel->clients table to SilcList and
8816 changed code accordingly.
8818 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8820 * Changed client's channel table to SilcList and changed code
8821 accordingly. Also changed SilcChannelClientEntry to include back-
8822 pointer to the channel so that client entry can use that structure
8823 as list as well and we have fast cross-reference to the channel.
8824 This change dramatically decreased the complexity of channel
8825 handling with client entry and vice versa (removed one extra
8826 loop when searching for channel entry from many functions).
8828 * Changed server->sim from table to SilcDList and changed code
8831 * NAMES command can now be used from user interface. It will show
8832 the user list on the channel, neatly.
8834 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8835 Code now saves realname of the user if it becomes available.
8837 * Renamed configure.in to configure.in.pre and made ./prepare
8838 script to automatically add correct version string to
8839 configure.in which it creates from configure.in.pre.
8841 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8843 * NAMES command reply now shows users mode with the nickname when
8846 * Moved silc_client_ch[u]mode[_char] functions from
8847 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8848 place sucks, they are utility functions and should be in some
8851 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8853 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8856 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8860 * Added TRQ (efficient deque and list library) into lib/trq. This is
8861 a very good list library that is currently used in the SILC. Defined
8862 SilcList API over the library because I didn't like the API very
8863 much. See lib/trq/silclist.h for the API and examples of how to
8864 use the API. Fixed various places in the code to use the new
8865 SilcList API. The SilcList is meant for lists that has a structure
8866 already defined as a list. It is not suitable to add just some
8867 context to the list (in TRQ, the context is the list actually).
8869 So, I defined SilcDList that can be used for the purpose where
8870 predefined list structure does not exit. This can be used as
8871 such list. Now some context just can be added to the SilcDList.
8872 Currently this list is not used in the SILC just yet, though there
8873 are a lot places where this can replace dynamically allocated
8874 tables and I will fix these places, later, to use SilcDList.
8875 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8876 and use TRQ internally).
8878 Also fixed some annoying warning messages that the original TRQ
8879 code generated. Also minor changes to TRQ's Makefile.in.
8881 * Added support for querying by Client ID to both WHOIS and
8882 IDENTIFY commands into server, as required by the protocol.
8884 * Removed method function pointers from SilcBuffer structure. They
8885 weren't used to anything and just increased the context size for
8886 no good reason. This change also made silc_buffer_alloc and
8887 silc_buffer_free functions inline functions.
8889 * Disabled command flooding detection support until it's fixed so
8890 that it accepts commands in but does not execute them more than once
8893 * Added silc_net_localhost(), to return local hostname, into
8894 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8895 that must be initialized before calling silc_client_init.
8897 * Added new function: silc_server_send_notify_on_channels to send
8898 notify messages to all channels client has joined. It is assured
8899 that the message is sent only once per client.
8901 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8902 lib/silcutil/silcutil.[ch] as silc_format function. The new
8903 function is generic and is used by server as well, not only by
8904 the logging routines.
8906 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8907 the provided version string was not acceptable. Added new function:
8908 silc_ske_check_version into lib/silcske/silcske.h. The function
8909 must be implemented by the application (client or server) and it
8910 does not reside in the SKE library. The function checks the version
8911 string remote end sent.
8913 * Added back pointers (to opaque context and to SilcSocketConnection)
8914 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8916 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8917 duplicate packet context structure.
8919 * Changed `notify' client operation to send same arguments as client
8920 receives from server except for ID's. ID's are mapped to correct
8921 ID entry and that is returned. Also, if channel entry is not sent
8922 by server but the notify is for channel the channel entry is sent
8923 to application (otherwise application doesn't know that it is for
8924 channel (library gets it from packet's Destination ID)).
8926 * Added silc_client_remove_from_channels into client library to
8927 remove a client from all channels it has joined to. Used when
8928 received SIGNOFF notify from server. Added also new function
8929 silc_client_replace_from_channels to replace old ID entry with
8930 new ID entry on all channels. Used when received NICK_CHANGE
8933 * Fixed ID Cache list handling in silc_idlist_get_client in
8934 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8935 to get (or query) client by ID.
8937 * Updated TODO list.
8939 * Added connection authentication status message defined by the
8940 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8941 support for these into the code in client and server side.
8943 * Added generic function silc_client_send_command to send any command
8944 with variable argument list. Application should use this function
8945 to send commands if the command functions provided by the library
8946 does not suite for the application's user interface needs.
8948 * Added new `failure' client operation. Application is notified about
8949 received failure packet if client is executing a protocol. In this
8950 case the protocol's execution has failed.
8952 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8953 is required by the protocol.
8955 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8956 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8959 * Added status flag to SilcSKE object to indicate realtime status
8960 of the SKE protocol.
8962 * Application receives now exactly same command reply arguments as
8963 the library receives from server. However, if ID is received the
8964 corresponding ID entry is returned to the application (eg. Client
8965 ID is mapped to correct SilcClientEntry entry and that is returned).
8966 Changed command_reply client operation due to this change.
8968 * Changed all ID's in commands and in command replys as ID Payloads.
8969 Change affected both client and server side codes.
8971 All ID's sent in SILC network (with execption of ID's in SILC
8972 Packet header) are sent in ID Payload to support variable length
8975 * Server now notifies nick changes and notifies all clients on
8976 the channels about the new nickname (about the new Client ID,
8979 * Implemented CMODE command to change channel modes. Supports all
8980 channel modes defined by the protocol specs except ban and invite
8981 lists. (Also, private channel key mode is supported but support for
8982 setting private channel key in client is missing, thus, this mode
8983 has no effect on client side (except that server requires that the
8984 client uses private channel key and normal channel traffic does not
8987 Also, invite mode works per se, but INVITE command does not work
8988 yet correctly, so you can set channel as invite only channel but
8989 inviting clients to the channel does not work (it is yet to be
8990 thought what's the best way to do it).
8992 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8993 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8994 Implemented CUMODE command to change user's mode on the channel.
8995 Supports all modes defined by the protocol specs.
8997 * Added NAMES command reply to return users modes on the channel.
8999 * Removed unnecessary and slow ciphers from lib/silccrypt.
9001 * Set SO_KEEPALIVE option to connection sockets by default.
9003 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
9005 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
9006 redefined the Notify Payload into protocol specs.
9008 * Added silc_id_payload_parse_id to get ID directly from raw
9011 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9013 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
9014 accept searching by Client ID as well.
9016 * Added support for LEAVE and SIGNOFF notify types in client library.
9018 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
9019 to parse ID Payload from raw data.
9021 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9023 * Added flags parameter into silc_ske_assemble_security_properties
9024 function in lib/silcske/silcske.[ch].
9026 * Changed notify client operation to fit better for notify messages
9027 sent by server. The notify payload received from server is now
9028 passed to the application (after parsing it to SilcNotifyPayload).
9029 It is application's responsibility to retrieve the arguments
9030 from the payload and show the message the way it wants. The message
9031 sent by server is implementation specific.
9033 * Changed public keys to comply with the protocol specification.
9034 Old public keys are not supported anymore and are not compatible.
9036 * Removed nickname from Channel Payload as the latest draft removed
9037 it. The client must resolve the nickname from the NAMES command
9038 reply received when it joined the channel.
9040 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
9042 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9044 * Fixed some errors in protocol specification drafts.
9046 * Created lib/silccore/silcnotify.c to implement Notify Payload
9047 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
9048 generic payloads described by protocol specifications. The file
9049 includes implementations for ID Payload and Argument Payload.
9051 * Changed Command Payload implementation to use the new Argument
9052 Payload. Changed command_xxxx_payload to command_payload_xxxx
9053 to comply with SILC coding conventions.
9055 * Added suppport for Argument Payload handling in Notify Payload
9056 implementation as protocol requires it. Added the new support
9057 into server and client lib as well.
9059 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9061 * Added support for multiple nicknames on same channel. [n] is
9062 added locally to the nickname if there are more than one same
9063 nicknames on the channel.
9065 * Server now sends all nicknames that matched WHOIS request.
9066 Client also shows the list received from server.
9068 * Added TOPIC command to client side. User can now set and show
9069 current topic on channel.
9071 * Added MOTD command to client and server. Also, server sends the
9072 motd when client connects to the server.
9074 * Changed version strings to comply ISO 8601.
9076 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9078 * Fixed protocol error handling in client library. It should now
9079 cope even if the SKE fails for some reason.
9081 * Made new protocol specification drafts for submitting to IETF.
9083 * Implemented TOPIC command to server in silcd/command.c.
9085 * Added two new notify types into lib/silccore/silcnotify.h:
9086 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
9087 notify nickname change and topic setting/change on a channel.
9089 * API change of command_reply operation in client library. The
9090 application gets now the status type received from server as well.
9092 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9094 * Removed the function just added to lib/silcutil/silcschedule.[ch].
9096 * Cras fixed and optimized the packet handling even further and
9097 it should work now. Minor change to the prototype of function
9098 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
9100 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9102 * Added new function into lib/silcutil/silcschedule.[ch]:
9103 silc_schedule_with_fd to select() a specified fd. The function
9104 returns after timeout expires or data arrives or goes. The
9105 function is used by packet routines to wait that all data is
9106 received from network.
9108 * Fixed data reading from network in lib/silccore/silcpacket.c.
9109 The code now assures that all data is read from the fd and then
9110 continues packet processing. This was a bug fix since the code
9111 used to drop some data in some circumstances.
9113 * Added new function into lib/silcclient/client.[ch]:
9114 silc_client_start_key_exchange to start key exchange after
9115 connection has been established to server. The code internally
9116 now uses this funtion but its main purpose was to provide it
9117 for applications that perform their own connecting. After
9118 application has created a connection it merely calls this
9119 function to start the key exchange between client and server.
9120 The library takes care of everything else after that.
9122 Updated also lib/silcclient/README to explain the usage of
9125 * Do not send to application information that connection has
9126 been established. Application gets notified it by connect
9129 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9131 * Applied cras's patch to add silc_schedule_one function. The
9132 function runs scheduler once and returns.
9134 * Fixed the scheduler after cras messed it up. The timeout
9135 handling works now as it's supposed to work.
9137 * Added into lib/silccore/ silcnotify.h to include notify
9138 message types support. Changed silc_server_send_notify*
9139 functions, in server.[ch], to support those new notify types.
9140 Added the support for the notify types into client library,
9141 as well. Added new notify client operation into ops.h in
9144 * Changed silc_server_packet_send_to_channel to send normal
9145 packets instead of just channel message packets. The function
9146 is now used to send the notify packets to channels. It is not
9147 used to send channel message packets anymore, as server never
9150 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
9151 va_arg()s as it seems to require it nowadays. I guess, if SILC
9152 is compiled with older va_arg() the new code should work anyway.
9154 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9156 * Splitted core library. Core library (lib/silccore) includes
9157 now only SILC protocol specific core (and common) components.
9158 Created new utility library (lib/silcutil) that includes more
9159 generic purpose stuff. The stuff for util library was taken
9160 from the old core library. This was minor and easy split.
9162 * Created SILC Client Library (lib/silcclient) that includes
9163 implementation of the SILC client without user interface. This
9164 was major move from silc/ directory. The code has been changed
9165 so that it is transparent towards the user interface. The
9166 silc/ directory includes now the same user interface as before
9167 and it uses the new client library. Read lib/silcclient/README.
9168 Basicly, the client library performs everything else related
9169 to SILC except user interface handling. Also, configuration
9170 files are considered to be part of user interface and library
9171 does not handle them.
9173 This change also changed a lot of structures, function naming etc.
9174 Most important change was that SilcClientWindow object was
9175 renamed to SilcClientConnection in the client library. Created
9176 also new file lib/silcclient/ops.h. Also added new files
9177 silc/local_command.[ch] and silc/client_ops.[ch].
9179 All these changes were made to make it easier for user interface
9180 designers to create what ever user interface for the SILC client
9183 It is also expected that the server will be moved to lib
9184 directory as well and SILC Server Library will be created;
9185 sometimes in the future.
9187 * Removed Local commands from lib/silccore/silccommand.h as
9188 they are application specific and new client library does not
9189 handle any of those anymore.
9191 * Several functions moved to lib/silcutil/silcutilc.[ch] from
9192 old client implementation in silc/.
9194 * Added support for callback functions in SILC_LOG_* macros.
9195 Application can now set its own callbacks that will be called
9196 instead of using the default functions that will always print
9197 the debug messages to stderr (or stdout). Also, debugging can
9198 now be disabled by setting silc_debug to FALSE and re-enabled by
9199 setting it to TRUE. Note, that logging will still work even
9200 if debugging is disabled.
9202 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
9203 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
9204 silc_log_reset_debug_callbacks.
9206 * To enable debugging in silc client one must give now -d
9207 option on command line.
9209 * Changed silc_schedule_init to automatically allocate task queues
9210 if they are not allocated before calling it.
9212 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9214 * Added GMP 3.1 into math library.
9216 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9218 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
9219 a channel in SILC network. The packet is used by servers and
9220 routers to notify other routers that user has left a channel.
9221 This little feature was missing until now. Added the feature
9222 to protocol specification as well.
9224 Added functions: silc_server_send_remove_channel_user and
9225 silc_server_remove_channel_user into server.[ch].
9227 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
9228 lib/silccore/silcpacket.h. However, they are not implemented
9231 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9233 * Fixed joining to a channel and sending channel messages
9234 between server and router. The channel message sending should
9235 now work inside a cell.
9237 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9239 * Fixed the private message sending between server and router.
9240 The private message sending should now work inside a cell.
9242 * Added silc_server_replace_id into server.[ch] to replace
9243 existing ID in the SILC network.
9245 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
9246 and silc_idlist_replace_server_id into idlist.[ch] in server.
9248 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9250 * Fixed the server to server connections. Server can again now
9251 connect to router. Router to router connections probably does
9254 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9256 * Added dynamic protocol registering support. Now protocols can
9257 registered and unregistered on the fly. Patch by cras.
9259 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9261 * Added lib/contrib directory to hold routines that some platforms
9262 don't have but are needed by SILC.
9264 * Added getopt.c, getopt1.c and getopt.h from GNU C library
9265 into lin/contrib to provide getopt() and getopt_long() for
9266 those who don't have it.
9268 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9270 * Added AWAY command to client. When away message is set and
9271 client receives a private message packet the client automatically
9272 replies to the sender with the away message.
9274 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
9275 bug seemed to be the cause of recent problems when compiling
9278 * Added version detection support to SKE protocol specification
9279 and added the new changes to the SKE implementation as well.
9280 There were other minor changes in the SKE protocol as well.
9282 Many changes in lib/silcske/silcske.[ch] and in
9283 lib/silcske/payload.[ch].
9285 * Added ^U functionality, clear input line. Patch from cras.
9287 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9289 * Mainly small bugfixes on core library. Fixed some debugging
9290 logging and buffer overflow in silclog.c.
9292 * Updated config.sub and config.guess on the distribution tree.
9294 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9296 * Added command lagging support in server. Client may execute
9297 commands now only once in two seconds.
9299 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9301 * Optimized packet reception. MAC computation and checking is now
9302 also more optimized. A lot previously duplicated code is now
9303 used as generic by both client and server.
9305 * Fixed key pair generation in clientutil.c
9307 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9309 * Added into lib/silccore/silcbufutil.[ch] new function;
9310 silc_buffer_realloc.
9312 * Moved generic packet sending/encryption functions to
9313 lib/silccore/silcpacket.[ch] from client and server. Some
9314 rewriting of the functions.
9316 * Moved all generic packet reception/decryption functions to
9317 lib/silccore/silcpacket.[ch] from client and server. The
9318 packet processing is now much cleaner in both client and server.
9319 These were major changes in both client and server.
9321 * Created many common functions in server to do packet sending.
9322 Previously code were duplicated a lot, this has been removed
9325 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9327 * Rewrote major parts of the ID cache system. Don't know
9328 whether it is better now or not but at least the API is more
9331 * Major rewrite on ID cache stuff on client because of the ID
9332 cache API changes. Added idlist.c to client.
9334 * Also major rewrite on ID cache stuff on server as well.
9335 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9336 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9337 in hand, instead they are all put into the ID cache system now.
9338 All server_idlist_* routines uses ID cache now instead of
9339 traversing its own lists (those lists does not exist anymore).
9340 SilcIDList though still exists. Also, SilcXXXEntry's are
9343 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9345 * Finally made the SKE implementation compliant to the protocol
9346 specification. All mp integers are now binary encoded as
9347 opposed being HEX encoded.
9349 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9352 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9353 functions: silc_[encode/decode]_pem. Also added function
9354 silc_encode_pem_file to PEM encode with newlines ('\n') for
9357 * SILC public keys are now encoded either PEM or binary. Same
9358 option is for private keys as well. By default private keys
9359 are binary encoded and public keys PEM encoded. Silly HEX
9360 encoding were removed.
9362 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9363 function to create fingerprints.
9365 * Fixed a bug in SHA1; does not change the original data anymore.
9367 * Partly implemented INFO command on client and server side.
9368 Fixed CLEAR command. Changes to SERVER command; show current
9369 server(s) when giving command without arguments. Added
9370 VERSION command to client.
9372 * Added check to server that unregistered connections cannot
9373 execute commands (unless it is specificly allowed).
9375 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9377 * Fixed screen refresh.
9379 * Fixed channel joining bug from client. On some circumstances
9380 client tried to join to a channel it had already joined.
9382 * Added public key verification process into client's protocol.c.
9383 The client now verifies the public key from user and saves
9384 it into ~./silc/serverkeys/ directory.
9386 Added into: clientutil.[ch]: silc_client_verify_server_key.
9388 * Changed SKE protocol's silc_ske_initiator_finish function
9389 to accept callback function that verifies the received public
9390 key. Removed old silc_ske_verify_public_key function.
9392 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9394 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9395 silc_pkcs_private_key[_data]_set.
9397 * Made the password and public authentication more cleaner in
9398 server's protocol.c.
9400 * Removed historic and obsolete protocol `channel_auth' from
9401 both client and server.
9403 * Removed wrong way of sending command status messages from
9404 server to client in server's command.c. The old way violated
9405 protocol specification.
9407 Changes to silccore/silccommand.[ch]: removed
9408 silc_command_encode_status_payload -> not needed anymore,
9409 changed silc_command_encode_payload_va to accept extra
9410 argument on variable argument list. The argument type must
9411 now be provided to the function. Also, added new function:
9412 silc_command_encode_reply_payload_va which is same as
9413 normal command_encode_payload_va except command status type
9414 is provided as extra argument.
9416 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9418 * Added ~./silc directory handling. The directory includes the
9419 public and private keys for the client.
9421 Added silc_client_check_silc_dir, silc_client_create_identifier
9422 and silc_client_load_keys.
9424 * Implemented SILC protocol compliant public key. Added public
9425 and private key saving to and loading from files.
9427 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9428 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9429 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9430 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9431 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9433 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9434 silc_pkcs_load_[public/private]_key.
9436 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9438 * Added silc_server_get_route (route.[ch]) to get connection
9439 data for the fastest route for given ID.
9441 * Implemented INVITE command on client and server. The command
9442 were re-defined in the SILC Protocol Specification and the
9443 implementation now complies with the specification.
9445 * Implemented PING command on client and server.
9447 * Implemented NAMES command on client and server. The server side
9448 supports currently only normal server not router server yet.
9449 Some changes to NAMES definition in SILC protocol specification.
9451 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9453 * Implemented LEAVE command on client and server.
9455 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9456 again. This change was made to the protocol as well. Server
9457 should not violate the protocol specification anymore.
9459 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9461 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9462 was tested. SOCKS4 was not but should work anyway.
