94 * Some strncat -> silc_strncat changes our the core and
97 * Added SILC_SKE_STATUS_SIGNATURE_ERROR and OUT_OF_MEMORY
98 errors. Added better error printing to SKE library.
99 Affected files lib/silcske/silcske.c, silcske_status.h and
102 * Save the PKCS key length even if only private key is set to
103 SilcPKCS. Affected file lib/silccrypt/silcpkcs.[ch] and rsa.c.
105 * Fixed the usage of silc_pkcs_get_key_len since it returns the
106 length in bits not in bytes. Affected files are
107 lib/silcske/silcske.c, lib/silccore/silcauth.c and
108 silcd/server_query.c.
110 Wed Oct 9 17:22:57 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
112 * Added silc_attribute_payload_encode_data to directly encode
113 the data into the attributes buffer. Renamed function
114 silc_attribute_payload_parse_list to silc_attribute_payload_parse.
115 Affected files are lib/silccore/silcattrs.[ch].

122 the Requested Attributes from the client. Fixed memory leak
123 in client entry freeing. Affected files silcd/server_query.c
126 * Added Requested Attributes support into SILC Client Library.
127 It is not able to send requested attributes in WHOIS command,
128 and also receive and process requested attributes. Added
129 silc_client_attribute_[add|del] and silc_client_attributes_get
130 functions. Added also `ignore_requested_attributes' to the
131 SilcClientParams to not use attributes in client. Affected
132 files are lib/silcclient/command.c, client_attrs.[ch],
133 silcclient.h, client_internal and client.[ch].
135 * Changed the silc_client_get_client_by_id to support Requested
136 Attributes, it takes them as argument now. Affected file
137 is lib/silcclient/silcclient.h, and idlist.c.
139 * Added -details option to WHOIS command in Irssi SILC Client
140 to support the requested attributes. By default it requests
141 all attributes. Affected file lib/silcclient/command.c and
142 irssi/doc/help/in/whois.in.
144 Tue Oct 8 17:58:28 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
146 * Add also SERVICE attribute for server-constructed attribute
147 data. Also digitally sign the attributes and add

149 silcd/server_query.c.
151 Mon Oct 7 18:25:35 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
153 * Changed the silc_attribute_payload_encode to support list
154 of attributes (function may be called several times to add
155 a new attribute). Removed the silc_attribute_payload_encode_list
156 function. The encoding function now also automatically encodes
157 the data, so the caller does not need to do that. Affected
158 files lib/silccore/silcattrs.[ch].
160 * Added support for replying on behalf of the user to the
161 Requested Attributes in WHOIS command in the server. Affected
162 file silcd/server_query.c.
164 * SILC_NOT_IMPLEMENTED macro use SILC_LOG_INFO now instead of
165 SILC_LOG_DEBUG. Affected file lib/silcutil/silclog.h.
167 Sun Oct 6 16:48:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

170 decryption error has occurred. Affected file silcd/server.c.
172 * Fixed a bug in backup router IP address comparison in
173 silc_server_backup_get.
175 Save now also the port of the server/router and use that
176 in comparison as well. Affected file silcd/server_backup.c.
178 * Normal server now reconnects to backup router automatically
179 if connection is lost to it. Affected file silcd/server.c.
181 Thu Sep 26 13:51:02 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
183 * If packet processing fails (like integrity check fails)
184 the connection is closed now. Affected files are
185 lib/silccore/silcpacket.c and silcd/server.c.
187 Mon Sep 23 10:59:39 CEST 2002 Pekka Riikonen <priikone@silcnet.org>

211 * Resumed client packet handling from server put the resumed
212 client on wrong list on router and caused the client not
213 be present on the network anymore. Now fixed to put the
214 client to correct list. Affected file silcd/packet_receive.c.
216 Wed Sep 18 15:13:48 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
218 * Various cleanup in error message output in config parsing code
219 and in server init code. Fixed error log files containing
220 too many newlines ('\n') in some situations. Affected files are
221 silcd/serverconfig.c, silcd/silcd.c, and silcd/server.c.
223 Wed Sep 18 10:51:23 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
225 * Use the reverse lookupped hostname in client internals
226 instead of one user provided us as remote server name.
227 Affected file lib/silcclient/client.c.
229 Mon Sep 16 12:02:54 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
231 * Added 'app_context' to silc_schedule_init. It is an
232 application specific context that is delivered to application
233 in task callback functions. Affected files are
234 lib/silcutil/silcutil.[ch].
236 * The hb_context in SilcSocketConnection is not freed
237 automatically anymore (application must free it). Freeing
238 it automatic is inconsistent. Affected files are
239 lib/silcutil/silcsockconn.[ch].
241 Sun Sep 15 22:16:19 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
243 * Added support for removing explicitly added client connections
244 in rehash and closing the client connections if they were
245 unconfigured in the rehash. Affected file silcd/server.c.
247 * Added support for aborting automatically pending commands
248 that never receives the reply (to avoid memory leaks).
249 Added also silc_server_command_pending_timed to set the
250 specific timeout for pending command. Affected files are
251 silcd/command[_reply].[ch].

258 * Changed the silc_get_time to accept time value as argument
259 or if zero is sent return current local time. Affected
260 file lib/silcutil/silcutil.[ch].
262 * Added STATS command to client library and Irssi SILC client.
263 Patch provided by Ville Räsänen <ville.rasanen@iki.fi>.
265 Wed Sep 11 09:22:00 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
267 * Assure that channel key is set before sending it. May
268 crash server otherwise. Affected file silcd/packet_send.c.
270 Tue Sep 10 09:50:08 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
272 * Assure that endless loop cannot happen with detached client
273 resolving on normal server. Added idlist status
274 SILC_IDLIST_STATUS_RESUME_RES. Affected files are
275 silcd/idlist.h and silcd/packet_receive.c.
277 Mon Sep 9 12:18:18 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
279 * Incoming file transfer request cannot use same session as
280 the sending session. This can happen when sending file to
281 yourself. Crashed the client on quit. Affected file
282 lib/silcclient/client_ftp.c. Bug #24.
284 Sun Sep 8 18:39:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
286 * Implemented the draft-riikonen-precense-attrs draft and
287 the Attribute Payload into the lib/silccore/silcattrs.[ch].
289 Sun Sep 8 13:13:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
291 * Distribute the SERVER_SIGNOFF notify also to local backup
292 routers from the primary router. The backup router may not
293 have the signing of local server directly connected and need
294 to know about the signoff. Affected file silcd/server_util.c.
296 * Use the primary router as the origin of the locally connected
297 server when it is disconnecting from the backup router since
298 that's where it really is coming from. Now the clients from
299 the disconnecting server are removed correctly and "shadow"
300 clients are not left to the backup router. Affected file
303 Sat Sep 7 22:26:50 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
305 * If normal server is standalone and found existing but disabled
306 channel, do not re-create the channel since it creates
307 duplicate same channels. Affected file silcd/server.c.
309 * Added anonymous client connections support to server. New
310 "anonymous" configuration option to ConnectionParams section
311 added. If set to true, the username and hostname information
312 of the client will be scrambled and anonymous user mode is
313 set automatically to the user. Affected files are
314 silcd/serverconfig.[ch], silcd/packet_receive.c and server.c.
316 Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
318 * In JOIN notify handling, mark that the cache entry of the
319 client cannot be expired. Can cause crashes on normal
320 server (asserts client->channels). Affected file is
321 silcd/packet_receive.c.
323 * From now on distribution versions are used as protocol versions
324 instead of by default using the Toolkit base version as protocol
325 version. Affected file prepare.
327 * Do not set the locally resolved hostname for local client
328 entry but take what server sends. This way the real hostname
329 is showed in WHOIS for yourself. Affected file is
330 lib/silcclient/idlist.c and lib/silcclient/client.c.
332 * Resolve local info with IDENTIFY when connecting to server.y
334 Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
336 * Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
337 for implied search (not needed on platforms which has native
338 pthreads library). Use --without-pthreads to disable threads.
339 Affected file is configure.in.pre
341 * Fixed --with-iconv on platforms which need to bypass (broken)
342 native iconv(). Affected file is configure.in.pre
344 Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
346 * Moved -C option parsing in Irssi SILC client at same time
347 as other options. The UI was initialized earlier and caused
348 problems on command line. Bug #16. Affected file is
349 irssi/src/silc/core/silc-core.c.
351 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
353 * Added global variable silc_log_timestamp that tells silclog
354 wether to print or not the timestamp in the logging files.
355 Affected file lib/silcutil/silclog.[ch].
357 * Added silcd configuration option Timestamp in the Logging
358 section. Affected file silcd/serverconfig.[ch],
359 doc/example_silcd.conf.in.
361 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
363 * Fixed fingerprint checking to check for entirely empty
364 fingerprint instead of two first bytes when determining
365 if it is set. Bug #18. Affected file silcd/command.c.
367 * Fixed duplicate PKCS name registering to not allow it.
368 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
370 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
372 * Conditionalize non-gcc compiler optimizations for various
373 platforms, enable those commented out. Cleanups.
374 Affected file lib/silcmath/mpi/configure.in
376 Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>
378 * silc_rng_exec_command() left zombie processes if command
379 didn't generate any output. Affected file
380 lib/silccrypt/silcrng.c
382 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
384 * Rewrote iconv checking, introduce --with-iconv for systems
385 which rely on libiconv. Check if iconv() provided by libc
386 is good enough, otherwise demand libiconv. Affected file
389 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
391 * Search for ldopen() also in libc. This enables SIM support
392 on *BSD systems. Based on patch from Alex Zepeda. Affected
393 file configure.in.pre
395 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
397 * Don't call AM_CONDITIONAL conditonally for SILC_THREADS.
398 This fixes prepare on *BSD systems. Affected file
401 Sun Aug 4 15:55:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
403 * More fixed for not having purge timeout for global clients
404 that are on channel. Affected files silcd/command_reply.c
407 * Fixed the rekey protocol to work with backup router connections.
408 Rekey packets are now allowed on disabled connections as
409 well. Affected files silcd/packet_send.c and server.c.
411 * Do not switch to be as backup router when shutting down and
412 closing the primary connection. Affected file silcd/server.c.
414 * Fixed memory leaks in backup router deleting. Added
415 silc_server_backup_free to free all data during shutdown of
416 server. Affected files silcd/server_backup.[ch].
418 Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
420 * Do not process commands if the sock->user_data is NULL.
421 Affected file silcd/command.c.
423 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
425 * Fixed buffer overflow and security problems (loosing bits
426 in CFB encryption) in SILC RNG. Problems reported by
427 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
429 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
431 * Added yet more checks that client is not expired on global
432 list if it is on channels. Affected file is
433 silcd/command_reply.c.
435 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
437 * Merged c0ffee's MIME signal patch which adds support for
438 sending also MIME messages in Irssi SILC Client, and handling
439 received MIME messages in a signal (and perhaps doing something
440 to non-textual MIME messages).
442 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
444 * Fixed pending command deletion in server and client library
445 to check the whole list instead of breaking after first found.
446 The affected files are silcd/command.[ch] and
447 lib/silcclient/command.[ch].
449 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
451 * Return NO_SUCH_CHANNEL error in USERS for channel that is
452 secret or private, otherwise it's possible to find out
453 whether a secret channel exists or not. Affected file
456 * If CMODE change fails during the mode setting, assure that
457 the old mode mask is set for the channel back. Affected
458 file silcd/command.c.
460 * Fixed passphrase saving on +a channel on normal server
461 after successful JOIN command. Affected file silcd/command.c.
463 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
465 * Remove server/router operator privileges in DETACH command,
466 since it's possible to resume to server where these
467 privileges would not be allowed for the client. Affected
468 file silcd/command.c.
470 * Do not set to wait for backup in rehash of the server.
471 Affected file silcd/server.c.
473 * Do not check listener sockets when counting how many
474 socket connections we have. Affected file is
477 * Do not announce disconnected clients that are remaining
478 in history (for WHOWAS). This is because SIGNOFF notify
479 for these has been sent earlier already. Affected file
482 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
484 * Buffer overflow with CUMODE command's mode->mode character
485 conversion. Reported by Ville Räsänen. Affected file
486 lib/silcutil/silcutil.c.
488 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
490 * Allow heartbeat packets to go disabled connections anyway.
491 Affected files silcd/server.c and silcd/packet_send.c.
493 * Do not broadcast New Channel packets with List flag set
494 in the packet to backup routers. The router must check
495 for the correctness of the packets before sending them.
496 It is possible that router will have enforce Channel ID
497 change and this would cause desync in the backup router.
498 Affected file silcd/packet_receive.c.
500 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
501 are handled in list parsing. They are not list packets
502 anymore. Affected file silcd/packet_receive.c.
504 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
506 * Stop waiting for backup router through the timeout, not
507 directly after backup router has arrived. Affected file
510 * Do not re-create channel keys and send them when removing
511 clients in server shutdown. Affected files are
512 silcd/server_internal.h and silcd/server_util.c.
514 * Notify distribution to backup routers was missing from
515 the silc_server_send_notify_dest function which caused
516 desyncing problems with backup router. Affected file is
519 * The client's channel removing was working wrong on
520 backup router. It assumed that it doesn't know global
521 information but backup router does know. For this reason
522 it could remove channel when it wasn't supposed to do that.
523 Affected file silcd/server.c and silcd/server_util.c.
525 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
527 * Stop for a couple seconds after badkup router has become
528 primary router. Affected file silcd/server.c.
530 * Added silc_server_remove_servers_by_server, which is used
531 to remove servers originated from some other server. Also
532 clients of those servers can be removed too. Affected file
533 silcd/server_util.[ch].
535 * When removing clients after a server has signed of remove
536 also all servers behind that server (unless they are known
537 to be available locally), and send SERVER_SIGNOFF for each
538 of the server separately. Also the signed off clients are
539 sent now separately per signed off server. The affected files
540 are silcd/server.c and silcd/server_util.[ch].
542 * All servers added with silc_idlist_add_server must always
543 have both "router" and "connection" pointers set. Otherwise,
544 bad server entries may be left around in the cache.
545 Affected file silcd/command_reply.c.
547 * Do not create the channel key in NEW_CHANNEL packet
548 processing if the channel is empty. Affected file
549 silcd/packet_receive.c.
551 * Completed backup router support for standalone routers.
552 Supports also servers in the cell that do not use the backup
555 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
557 * Fixed a bug in silc_string_regexify which did not add '^'
558 at the start of each string, and thus the matching was
559 not explicit. For example ban list iikone@*!*@* would
560 match also "priikone", which is wrong, it would have to be
561 *iikone@*!*@* to match also "priikone". Affected
562 file lib/silcutil/unix/silcunixutil.c.
564 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
566 * Enable all local server connections before updating client
567 caches when we've become backup router. Otherwise, signoff
568 packets may not reach the clients. Affected files are
569 silcd/server.c and silcd/server_util.[ch].
571 * Fixed a bug in version string parsing which could crash
572 the program with specially formatted version string.
573 Bug reported and patch provided by Ville Räsänen. Affected
574 file lib/silcutil/silcutil.c.
576 * Handle the disconnection immediately when DISCONNECT
577 packet is received in server. Affected file silcd/server.c.
579 * Primary router now waits a short time (10 seconds) for
580 backup router connection before accepting any other
581 connection (except local). Affected file silcd/server.c,
584 * Fixed a crash in client libary in NICK_CHANGE notify when
585 NICK_CHANGE arrived for client entry we are resolving
586 currently. Affected file lib/silcclient/client_notify.c.
588 * Call the sconn->callback completion even if error had
589 occurred. Start reconnecting always if connection to
590 primary router fails during backup router protocol.
591 Affected files silcd/server.c and server_backup.c.
593 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
595 * Added functions silc_server_send_opers and
596 silc_server_send_opers_notify to send packets stricly
597 to operators. Added macro SILC_SERVER_SEND_OPERS macro
598 to send variable argument notify to operators.
599 Affected files silcd/packet_send.[ch] and silcd/server.h.
601 * Removed UMODE rights checking with UMODE_CHANGE notify.
602 Affected file silcd/packet_receive.c.
604 * Server/router operator now receives notify when network
605 switches to backup router and when it resumes the use of
606 primary router. Affected file silcd/server.c and
607 silcd/server_backup.c.
609 * Fixed the updating of client information after backup
610 resuming protocol is over; update all except local clients
611 to the new primary router. The affected file is
614 * Added support for closing active connections in rehash
615 that were unconfigured by the user. Supports currently
616 closing server and router connections. Affected file
619 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
621 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
623 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
624 is NULL since seems that on some platforms NULL is allowed
625 and on some it's not. Fallback encoding is used instead.
626 Affected file lib/silcutil/silcstrutil.c.
628 * Fixed statistics updating for incoming server connection
629 which could cause problems when re-connecting. Affected
632 * Preliminary backup router support for standalone router
633 added. Affected files in silcd/.
635 * Mark server connections in backup router disabled before
636 and after backup protocol. Affected file is
637 silcd/server_backup.c.
639 * Added support for reconnecting to remote server connection
640 even if the protocol fails, and if the configuration wants
641 us to keep trying to connect anyway.
643 Server connection is not allowed to backup router if
644 backup router does not have connection to primary router yet.
646 Affected file is silcd/server.c.
648 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
650 * Added silc_client_udpate_server function to update changed
651 server info. Affected file lib/silcclient/idlist.[ch].
653 * Added check for server entries that are being resolved when
654 notify is received. If being resolved, handle the received
655 notify only after it's resolved so that all notifys are
656 handled in same order as received from the server.
658 Added similar resolver check to channel entries. Every
659 notify that cause resolving of any information that affects
660 channel entry marks the channel entry in waiting state.
661 After whatever resolving is over the waiters are signalled
662 and only then the notifys are handled in the same order
663 as delivered from the server.
665 Affected files are lib/silcclient/idlist.[ch], and
668 * Fixed KILLED notify handling in normal server. Affected
669 file silcd/packet_receive.c.
671 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
672 is locally connected, or was locally connected (but may
673 be detached and connection is not active). Added also
674 SILC_IS_LOCAL for checking this status. Affected files
675 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
676 silcd/server.c and silcd/server_internal.h.
678 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
680 * Don't send or handle TOPIC_SET if topic is already set and
681 is same as being set. Affected files silcd/command.c and
682 silcd/packet_receive.c.
684 * Fixed CMODE change rights checking to work correctly when
685 removing modes by operator. Affected file is
688 * Fixed some handling with New Channel packet in router and
689 fixed some CMODE_CHANGE notify handling in server and router.
690 Affected file is silcd/packet_receive.c.
692 * Changed "disconnect" client operation to include the
693 reason of the disconnection and optional disconnection
694 message. Affected file lib/silcclient/silcclient.h.
696 * Made the compilation of lib/contrib/ stuff conditional.
697 Affected files configure.in.pre, lib/contrib/Makefile.am.
699 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
701 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
702 to the sender of the notify too, to avoid situation where two
703 notifys are in the network at the same time going to oppsite
704 directions. Affected file silcd/packet_receice.c.
706 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
708 * Delete the client from channel even if the cilent->id is
709 NULL. It was possible that client was deleted without
710 removing from channels (theoretically at least). Affected
711 file silcd/server.c and silcd/server_util.c.
713 * Free the client data too when resuming is not successful.
714 Affected file silcd/packet_receive.c.
716 * Merged some code from c0ffee's silc-plugin. Affected files
717 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
719 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
720 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
721 to the primary router connection, the other one returns
722 TRUE if packet must be broadcasted to network.
724 * All notifys that are destined to primary router (to network)
725 are now automatically sent to backup routers even if the
726 router is standalone (and has backup router). Affected files
729 * Added --without-irssi and --without-silcd configuration
730 options for disabling the compilation of these applications.
731 Affected file configure.in.pre and prepare.
733 Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
735 * Implemented SILC_STRING_BMP and SILC_STRING_UNIVERSAL for
736 UTF-8 encoding and decoding. Added also new encodings
737 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
739 Added also SILC_STRING_LANGUAGE which is language and charset
740 specific encoder and decoer for those platforms that support
741 iconv(). It can convert the UTF-8 to and from the locale
742 specific character set.
744 Affected file lib/silcutil/silcstrutil.[ch].
746 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.
748 * Added function silc_get_command_name to the file
749 lib/silcutil/silcutil.[ch].
751 * Improved the server debug output a bit. Affected files are

756 * Save the channel passphrase when received succesful JOIN
757 command reply from router, on normal server. Otherwise
758 joinig +a channels from normal server is not possible.
759 Affected file silcd/command.c.
761 * Fixed a bug in TOPIC_SET notify handling. The notifier
762 may be other than client too, like server or channel.
763 It expected it to always be only client and ignored the
764 notify. Affected file silcd/packet_recieve.c.
766 * Removed some (unnecessary) debug printing from
767 lib/silccore/silcid.c and lib/silccore/silcargument.c.
769 * Do not force CMODE_CHANGE when server is announcing new
772 Router announces stuff only after server reannounces channel
773 after CHANNEL_CHANGE notify.
775 These fixes optimizes the announcing procedure, and perhaps
776 fixes some problems too. Affected file silcd/packet_receive.c.
778 * Fixed SERVER_SIGNOFF sending to local clients. It was
779 totally broken and sent the notify to all local clients,
780 instead of only to those that was on same channel as the
781 signing off clients. Affected file silcd/server_util.c.
783 * Added -D option to server. It can be used to give debug
784 level. The levels are from 0 - 99, and are predefined for
785 smooth server debugging. (see silcd.c for the predefined
786 levels). Affected file silcd/server.c.
788 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

794 Tue Jun 18 17:14:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
796 * When authenticating as founder during JOIN command, check
797 that the one authenticating becomes the only founder on the
798 channel. Affected file silcd/command.c.
800 * Better checking for founder mode setting when CUMODE_CHANGE
801 notify is received. Affected file silcd/packet_receive.c.
803 * Close all connections when shutting down the server by sending
804 DISCONNECT packet. Close all listeners too when shutting
805 down the server. Affected file silcd/server.c.

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

881 else is demoted. Affected file silcd/command.c.
883 * Added error printing of any error that has occurred during
884 any command in client library. Affected file is
885 irssi/src/silc/core/client_ops.c.

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

1576 * Some client implementations quit network by doing first LEAVE
1577 and then immediately SIGNOFF (like Bombyx). We now do check
1578 after a short time after LEAVE notify and check whether the
1579 client is still valid after LEAVE, and if not we remove it from
1580 cache. Affected file is lib/silcclient/client_notify.c.
1582 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1584 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1585 it's good not to have security holes here.
1587 * Fixed a negative refcount situtuation for the config context.
1588 Affected file is silcd/serverconfig.c.
1590 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1592 * ROBOdoc documented lib/silcutil/silcutil.h.
1594 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1596 * Optimized even more the SilcPacketContext structure. Now
1597 totally saved 16 bytes of memory per context after optimization.
1598 Affected files are lib/silccore/silcpacket.[ch].
1600 * Made strict checks for valid SILC IDs. Affected file is
1601 lib/silccore/silcid.c.
1603 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1605 * Changed the object argument for silc_cipher_register,
1606 silc_hash_register, silc_hmac_register and silc_pkcs_register
1607 to const. Affected files are lib/silccrypt/silccipher.[ch],
1608 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1610 * Changed the silc_get_username and silc_get_real_name to
1611 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1613 * Fixed the Irssi SILC Client to use the silc_get_username and
1614 silc_get_real_name insted of glib routines since the glib
1615 routines only corrupt stack. Fixes the Irssi SILC to work in
1616 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1618 * Fixed the Irssi to not use g_get_home_dir since it crashes
1619 or returns garbage on cygwin and corrupts stack. Added function
1620 get_home_dir to Irssi routines. Affected files are
1621 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1623 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1625 * Made some structure optimizations. SFTP memory FS MemFSEntry
1626 entry structure. Optimized SilcTask structure. Optimized
1627 SilcPacketContext structure.
1629 Affected files lib/silcsftp/sftp_fs_memory.c,
1630 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1632 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1634 * And yet again reverted back the config thing since Johnny
1635 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1638 * Fixed memory leaks from config object. Affected files are
1639 silcd/serverconfig.[ch].
1641 * Added support for adding new connections to the server in rehash.
1642 After rehash they take effect.
1644 Added support for changing the maximum allowed connections in
1645 rehash. The number can grow but going smaller is not supported.
1647 Added function silc_server_num_sockets_by_remote to the
1648 silcd/server_util.[ch].
1650 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1652 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1654 * Added preliminary checking during config parsing for a valid
1655 public/private key and removed further checks in the code.
1656 Affected files are silcd/serverconfig.[ch], server.c.
1658 * Moved functions silc_server_drop() and silc_server_daemonise()
1659 from server.c to silcd.c since they are stricly related to
1660 the application activity.
1662 * Reverted a small part of the automatic ref/unref since
1663 it caused a double unref in some situations. Affected
1664 files are silcd/silcd.[ch], server.c, serverconfig.c.
1666 * Added some .cvsignore files in the lib directory.
1668 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1670 * Fixed silc_net_gethostbyaddr to correctly resolve by
1671 address. Affected file lib/silcutil/silcnet.c.
1673 * Fixed the notify relaying to client. The HMAC to be used
1674 with relayed packets ws wrong and caused decryption failure
1675 at the client end. Affected file is silcd/packet_receive.c.
1677 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1679 * Created new branch silc_protocol_1_0_branch.
1681 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1683 * Changed the silc_server_config_* routines to be SilcServer
1684 independent. They are now officially application specific code
1685 and not part of generic server implementation. Affected files
1686 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1688 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1690 * Added automatic referencing of config context in the
1691 silc_server_config_alloc, and automatic unreferencing in the
1692 silc_server_config_destroy. Affected files are
1693 silcd/serverconfig.[ch], silcd/silcd.c.
1695 * Fixed the silc_log_quick handling in the logging routines.
1696 It didn't log quickly when it was TRUE. Affected file is
1697 lib/silcutil/silclog.c. Also the flush delay was set even
1698 if it was 0 in config file. Affected file is
1699 silcd/serverconfig.c.
1701 * Added support for changing key pair of the server in rehash.
1702 Affected file silcd/server.c.
1704 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1706 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1707 too early, before getting the channel entry. Affected file
1708 is silcd/packet_receive.c.
1710 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1712 * Added functions silc_server_config_[ref/unref], these are used
1713 to prevent that the config object is destroyed.
1715 No longer directly affect global variables silc_log_quick and
1716 silc_log_delay, they are first cached inside the config object
1717 and then applied with silc_server_config_setlogfiles().
1719 silc_server_config_set_defaults() is now internal to
1720 serverconfig.c, there are no reasons to show this internal stuff
1723 Affected files are silcd/serverconfig.[ch].
1725 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1726 fprintf's to stderr, since some code may be executed again after
1727 the server went into the background. Affected files are
1730 * Added rehash support. Added function silc_server_rehash() that
1731 will perform all the basic tasks of the rehashing procedure.
1733 * Added command line option `-x, --hexdump'. This will enable the
1734 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1735 The option `--hexdump' implies `--debug'.
1737 * Fixed a bad bug in the logging APIs (silcutil library) where
1738 the application would crash after calling silc_log_reset_all().
1740 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1742 * Fixed the KICKED notify handling in client library to
1743 correctly remove the channel and all entries from the
1744 channel when I was kicked. This bug crashed the client.
1746 Fixed yet another but in KICKED notify handling to remove
1747 the kicked client correctly from the channel.
1749 Affected file is lib/silcclient/client_notify.c.
1751 * Fixed a minor bug in looking up correct client entry
1752 in KICKED notify in server. Affected file is
1753 silcd/packet_receive.c.
1755 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1756 sources correctly to distribution. Fixes --with-gmp option.
1758 * Removed the manual rehashing from ID Cache, and changed it
1759 to use the SILC Hash Table's auto rehash feature. Affected
1760 file is lib/silccore/silcidcache.c.
1762 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1764 * Fixed a bug in the silc_client_nickname_format function that
1765 handles the multiple same nickname formatting. Two clients
1766 with same nickname caused problems after the first one left
1767 and rejoined. It didn't format the nickname correctly.
1768 Affected file is lib/silcclient/idlist.c.
1770 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1772 * Don't change the topic if olod topic is same as new one.
1773 Affected file is silcd/packet_receive.c.
1775 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1777 * Added cross-reference support to the SILC Documentation
1778 generator. All types across all HTML files are now cross-
1779 referenced. Affected files util/robodoc/generator.c and
1780 scripts/silcdoc/silcdoc.
1782 * Added file lib/silcutil/silctypes.h to include all the
1783 arithmetic type definitions and some macros. Removed
1784 includes/bitmove.h and moved macros to silctypes.h.
1786 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1788 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1790 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1792 * Added `type' argument to silc_id_payload_parse_id function which
1793 now returns the type of the ID to the sent pointer. Affected
1794 file is lib/silccore/silcid.[ch].
1796 * Added check for CMODE_CHANGE notify type that mode change is
1797 allowed by the sender. Affected file silcd/packet_receive.c.
1799 * Added check for CUMODE_CHANGE notify type that mode change is
1800 allowed by the sender. Affected file silcd/packet_receive.c.
1801 Added the ID type as CUMODE_CHANGE notify type as argument
1802 to the `notify' client operation. Affected files are
1803 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1805 * Added function silc_client_add_server to the client library.
1806 Added support for resolving also channel and server info when
1807 received unknown entity in notify packet. Affected files are
1808 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1810 * Added function silc_command_get_status to return the command
1811 status from the command reply's argument payload. Affected files
1812 are lib/silccore/silccommand.[ch].
1814 * Added check for KICKED notify type that the kicking is
1815 allowed by the client. Affected file silcd/packet_receive.c.
1817 * Created function silc_get_input which can be used to get input
1818 (echo on or off) from user on command line. Affected files are
1819 lib/silcutil/silcutil.[ch].
1821 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1823 * Optimized silc_server_packet_relay_to_channel function.
1824 Added new function silc_channel_message_payload_encrypt which
1825 can be called directly if channel message payload needs to
1826 be encrypted and is already encoded (no need to call _encode
1827 function). Packet relaying is now done by router without any
1828 extra memory allocations. Affected files are
1829 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1830 silcd/packet_send.c.
1832 * Fixed the INVITE notify handling. It took wrong arguments
1833 as invite list and invite delete. Affected file is
1834 silcd/packet_receive.c.
1836 * Added check for TOPIC_SET notify type that the topic change is
1837 allowed by the client. Affected file silcd/packet_receive.c.
1839 * Added check for INVITE notify type that inviting is allowed by
1840 the client. Affected file silcd/packet_receive.c.
1842 * Changed the silc_server_client_on_channel to return the
1843 SilcChannelClientEntry as well. Moved the function
1844 silc_server_check_cmode_rights to server_util.[ch].
1845 Affected files are silcd/server_util.[ch], silcd/command.c.
1847 * Added function silc_server_check_umode_rights to check whether
1848 changing client's user mode is allowed. Added check for
1849 UMODE_CHANGE notify type that the umode change is allowed
1850 by the client. Affected files are silcd/server_util.[ch],
1851 silcd/packet_receive.c and silcd/command.c.
1853 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1855 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1856 ID length. It ignored that ID can be IPv6 based as well.
1857 Affected file lib/silccore/silcpacket.h.
1859 * Fixed the silc_id_id2str and silc_id_str2id to take the
1860 IPv6 address offset's into consideration. Affecte file is
1861 lib/silccore/silcid.c.
1863 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1865 * Fixed the internal Unix scheduler functions to check for
1866 NULL context they may receive. The affected file is
1867 lib/silcutil/unix/silcunixschedule.c.
1869 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1871 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1872 can specify different directory with --home command line
1873 parameter. Affected files irssi/src/silc/core/client_ops.c,
1876 * SILC-specific commands aren't now executed if the active server
1877 isn't of SILC-type, so there won't be problems with having
1878 IRC and SILC protocol support in same client. Affected files
1879 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1882 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1884 * Improved the signal support in SILC Schedule. Added new
1885 function silc_schedule_signal_call which is used by application
1886 to mark a signal to be called. It is now safe to perform
1887 any kind of tasks in signal callbacks since it is guaranteed
1888 that the application specified signal callback is called
1889 after the signal is over. Affected files are
1890 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1892 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1894 * Added `name' field to SilcChannelPrivateKey to represent
1895 application given name for the key. Moved also the context from
1896 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1897 Added the `name' argument also to the function
1898 silc_client_add_channel_private_key.
1900 Added function silc_client_current_channel_private_key to set the
1901 current channel private key in use.
1903 Added "change" command to KEY command which can be used to change
1904 the current channel private key. Bound the command also to
1905 alt+K (Alt+Shift+k).
1907 Also affected files lib/silcclient/client_channel.c,
1908 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1910 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1912 * Added silc_rng_get_byte_fast function in to the
1913 lib/silccrypt/silcrng.[ch].
1915 * Changed the interface of silc_packet_assemble and the
1916 silc_packet_send_prepare. If silc_packet_assmble is now
1917 called the application does not call silc_packet_send_prepare
1918 because the library will call it automatically. These
1919 interfaces now also return a reference to the outgoing buffer
1920 which includes the assembled packet, which the application can
1921 use to encrypt the packet.
1923 Affected files are lib/silccore/silcpacket.[ch],
1924 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1925 silcd/packet_send.c, server_backup.c and packet_receive.c.
1927 * Fixed a packet sending bug on very high load, where outgoing
1928 packet queue wasn't handled correctly and packets got corrupted.
1929 Affected files are lib/silcutil/*/silc*sockconn.c,
1930 lib/silcclient/client.c and silcd/server.c.
1932 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1934 * Added macro SILC_PACKET_DATALEN which can be used during
1935 packet assembling to check whether the data to be added to
1936 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1937 len is truncated until it fits it.
1939 Added checks for maximum length of channel message payload and
1940 private message payload also.
1942 Added checks for maximum packet length in server and in
1945 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1946 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1947 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1948 lib/silcclient/client_prvmsg.c.
1950 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1952 * Added silc_server_packet_queue_purge call to the
1953 silc_server_disconnect_remote to assure that all data in the
1954 queue before disconnecting is sent to the network. Affected
1955 file silcd/server.c.
1957 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1959 * Added the deleting of server's own ID cache entry to the
1960 silc_server_free function. Free also everything else that
1961 has been allocated in silc_server_init. The affected file
1964 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1966 * Added functions silc_parse_version_string, silc_version_to_num,
1967 and silc_ske_parse_version to parse SILC protocol style version
1968 strings. Affected files lib/silcutil/silcutil.[ch] and
1969 lib/silcske/silcske.[ch].
1971 * Added new configuration params: version_protocol, version_software
1972 and version_software_vendor to specify what version the remote
1973 host must at least be to be able to connect to server. The vendor
1974 string can be regex matched too. Added new function
1975 silc_server_connection_allowed to check maximum number of allowed
1976 connections, and allowed versions for incoming connections.
1977 Affected files are silcd/server.c, server_util.[ch] and
1980 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1982 * Added preliminary support for signals in scheduler. The
1983 signals we care about are now blocked always when the scheduler
1984 is locked. This way we can synchronise the use of signal with
1985 scheduler. It is guaranteed that when signal occurs the scheduler
1986 is not locked, and thus new tasks can be safely added to the
1989 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1990 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1991 Added new platform specific routines
1992 silc_schedule_internal_signals_[un]block and
1993 silc_schedule_internal_signal_[un]register.
1995 Added new functions to SILC Schedule API:
1996 silc_schedule_signal_[un]register. Each signal that application
1997 is going to use should be registered to the scheduler.
1999 Affected files are lib/silcutil/silcschedule.[ch],
2000 lib/silcutil/*/silc*schedule.c.
2002 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2004 * Check for unauthenticated client and server in the
2005 silc_server_new_client and silc_server_new_server functions.
2006 Affected file silcd/packet_receive.c.
2008 * Added function silc_string_is_ascii to check whether given
2009 string is 7-bit ASCII string. Affected files are
2010 lib/silcutil/silcutil.[ch].
2012 * Added function silc_id_is_valid_server_id into the
2013 silcd/serverid.c and added checking for valid Server ID's in
2014 silc_server_new_server. The Server ID must always be based
2015 on the server's public IP address.
2017 * Added logging of DISCONNECT packet message in the server.
2018 Affected file silcd/server.c.
2020 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2022 * Changed all library interfaces that use Global RNG to also
2023 accept SilcRng as argument. Affected files are
2024 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
2025 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
2026 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
2027 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
2028 lib/silccrypt/rsa.c.
2030 * Added function silc_pkcs_generate_key to the
2031 lib/silccrypt/silcpkcs.[ch] for applications so that they
2032 don't need to do pkcs->pkcs->init calls anymore.
2034 * Remove SilcSocketConnection from the SFTP API since it really
2035 wasn't needed there. The application has the information
2036 saved in its contexts anyway and the SFTP layer doesn't need
2037 know about it. Affected files lib/silcsft/silcsftp.h and
2038 lib/silcsftp/sftp_[server/client].c.
2040 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
2041 The SilcSimContext is not SilcSim.
2043 * Fixed possible buffer overflows in silc_id_render in the
2044 lib/silcutil/silcutil.c.
2046 * On EPOC the global crypto module lists are not used at all
2047 in the crypto library. Added support for using the constant
2048 algorithm list on EPOC. Affected files are
2049 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
2052 * Fixed the handling of third parameter of KICKED notify, since
2053 it was mistakenly updated to SILC Protocol 1.0 even though it
2054 is to be included in 1.1. Since it is not in 1.0 it is not
2055 mandatory, and this fix now handles it only if it is provided,
2056 and it is not error if it is not provided. Affected file
2057 lib/silcclient/client_notify.c.
2059 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2061 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
2062 client. Affected file irssi/src/silc/core/client_ops.c.
2064 * Merged with Irssi 0.8.4 from irssi.org CVS.
2066 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2068 * Check for valid socket connection in client entries before
2069 sending any messages. Fixes a crash, but doesn't fix some
2070 other underlaying bug that is lurking there. Affected
2071 file silcd/packet_send.c.
2073 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
2075 * $usermode, $cumode and $cumode_space expandos shouldn't do

2096 file lib/silcutil/silcutil.[ch].
2098 * Added support for specifying multiple public keys for Client
2099 connection section in server configuration file. This makes it
2100 possible to accept multiple public keys from same host, or to
2101 make a section that accepts any incoming host, and have the
2102 accepted public keys listed in the section.
2104 Added functions silc_sever_[find/get]_public_key, added the
2105 support for this actually to all connection sections but only

2217 old name went against naming convention. Applications now
2218 include "silcclient.h" instead of "clientlibincludes.h".
2219 Removed includes/clientlibincludes.h, it is redundant now.
2221 * Renamed includes/version.h to silcversion.h.
2223 * Added really preliminary support for OS/2 into the util
2224 library. Only thread & mutex API is implemented, others

2281 the SKE interface a bit.
2283 * Fixed padding problem in PKCS#1. The padding was not actually
2284 random since the random number generator was used incorrectly.
2285 This security bug affects only when encrypting with PKCS#1, and
2286 it is not currently used at all in SILC. SILC only use signing
2287 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

2372 the connection configuration object from the SilcServerConnection
2373 object instead of finding it during the connecting phase.
2374 Added the configuration object to SilcServerConnection struct.
2375 Affected files silcd/server_internal.h, server.c.
2377 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2379 * Add the client on channel after it was resolved at the
2380 channel message receiving, and it was not already on the
2381 channel. Affected file lib/silcclient/client_channel.c.

2403 public key is set. If not set, public key is preferred.
2404 This has effect only when being initiator (responder will try
2407 Added support for authentication with passphrase and public key
2408 at the same time. The passphrase is tried first always since
2409 it is faster to check.
2411 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2413 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2459 * Fixed the file transfer's key agreement payload to include
2460 zero port also if the hostname is NULL because it could not
2463 Call file transfer monitor callback now also if error occurs
2464 during key agreement protocol.
2466 Changed the silc_client_file_send interface to return the
2467 SilcClientFileError instead of session id. The session ID
2468 is returned into pointer provided as argument.

2487 * Fixed the channel message payload decryption in the function
2488 silc_channel_message_payload_decrypt to not modify the original
2489 buffer before it is verified that the message decrypted
2490 correctly. Otherwise, next time it is called with correct
2491 channel key it won't encrypt since the payload is corrupted.
2492 Affected file lib/silccore/silcchannel.c.
2494 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2507 the table with foreach callback. The current entry may
2508 become invalid in the callback but it was referenced after
2509 the callback returned.
2511 Do not allow auto rehashing of hash table during the
2512 silc_hash_table_foreach operation, for same reasons as it is
2513 not allowed for SilcHashTableList. Affected files are
2514 lib/silcutil/silchashtable.[ch].
2516 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

2540 * Fixed a bug in hash table tarversing. While the hash table
2541 is traversed with SilcHashTableList the table must not be
2542 rehashed. It is now guaranteed that auto rehashable tables
2543 are not rehashed while tarversing the list. Also defined that
2544 silc_hash_table_rehash must not be called while tarversing
2545 the table. Added function silc_hash_table_list_reset that must
2546 be called after the tarversing is over. The affected files are
2547 lib/silcutil/silchashtable.[ch].
2549 * Changed all hash table traversing to call the new
2550 silc_hash_table_list_reset in server and in client library.
2552 * Added function silc_client_on_channel to return the
2553 SilcChannelUser entry if the specified client entry is joined
2554 on the specified channel. This is exported to application as
2555 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

2564 lists correctly. Affected file silcd/command.c.
2566 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2568 * When sending JOIN command to router for processing the
2569 sender's old command identifier was not saved back to the
2570 sender's command context, fixed now. The affected file is
2573 * Create the key in JOIN command of the router did not return
2574 the channel key, added check for this. Affected file is
2577 * Fixed a channel ID update bug in JOIN command reply. Do
2578 not directly upgrade the ID but call the function
2579 silc_idlist_replace_channel_id if the ID was changed.
2580 Affected file silcd/command_reply.c.
2582 * Fixed memory leaks from command calling if it would fail.
2583 Affected file silcd/command.c.

2598 with server connections. Later this will be configurable
2599 in config file after new config file is done. Affected file
2602 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2604 * Fixed a crash in server related to channel announcements.
2605 Affected file silcd/server.c.
2607 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2609 * Fixed memory leaks in silc_server_create_new_channel*
2610 functions. Affected file silcd/server.c.
2612 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2613 which ID was changed. This way the router will send the
2614 user list for the channel again, and server won't be in
2615 desync in some rare circumstances. Affected file is
2616 silcd/packet_receive.c.
2618 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2620 * Check for NULL socket pointer in the function
2621 silc_server_packet_send_to_channel_real. Affected file
2622 silcd/packet_send.c.
2624 * Fixed the BAN notify handling to correctly remove ban
2625 list. Affected file silcd/packet_receive.c.
2627 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2629 * Fixed some header addition to Toolkit distribution in
2630 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2632 * Added lib/silcclient/client_ops_example.h as an template
2633 file for application programmers to quickly start using
2634 the SilcClientOperation functions in their application.
2635 Updated the lib/silcclient/README as well to tell about this
2636 nice file made available.
2638 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2640 * Call silc_server_remove_from_channels when removing client
2641 entry when NO_SUCH_CLIENT_ID was received. Affected file
2642 is silcd/command_reply.c.
2644 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2646 * Added server & router operator statistics updating. Affected
2647 file silcd/packet_receive.c and silcd/command.c.
2649 * Fixed the SERVER_SIGNOFF notify handling on normal server
2650 not to save the history information for clients. Same was
2651 fixed earlier in remove_clients_by_server function, but not
2652 here. Affected file silcd/packet_receive.c.
2654 * Raised the default connection-retry count from 4 to 7 in
2655 server. Affected file silcd/server.h.
2657 * Cancel any possible reconnect timeouts when we start the
2658 key exchange. Affected file silcd/server.c.
2660 * Do not reconnect on connection failure when SCONNECT was
2661 given. Affected files silcd/server.[ch].
2663 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2665 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2667 * Fixed the NICK command to always give the unformatted
2668 nickname to the one giving the NICK command. If unformatted
2669 nickname is cached already it will be formatted and the
2670 local entry will always get the unformatted nickname.
2671 Affected file lib/silcclient/idlist.c.
2673 * Fixed some double frees from client library commands.
2674 Affected file is lib/silcclient/command.c.
2676 * Fixed CUMODE command in server to assure that no one can
2677 change founder's mode than the founder itself, there was a
2678 little bug. Affected file silcd/command.c.
2680 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2682 * Removed the SilcClientCommandDestructor from the client
2683 libary, it is not needed anymore. Affected files are
2684 lib/silcclient/silcapi.h, command[_reply].[ch],
2685 client_notify, idlist.c.
2687 * Fixed GETKEY command to first resolve client, and then
2688 resolve the server only if the client was not found, instead
2689 of resolving both at the same time. Affected file is
2690 lib/silcclient/command.c.
2692 * Added silc_client_start_key_exchange_cb and lookup the
2693 remote hostname and IP address before starting the key
2694 exchange with server. The affected file is
2695 lib/silcclient/client.c.
2697 * The server's public key is now saved using the IP address
2698 of the server and not the servername for the filename.
2699 The hostname public key filename is checked as an fall back
2700 method if the IP address based filename is not found.
2702 Fixed the GETKEY command to save the fetched server key
2703 in correct filename.
2705 Print the remote server's hostname now when new key is
2706 received during connection process. Affected file is
2707 irssi/src/silc/core/client_ops.c.
2709 * Return always our own public key to the client if it asks
2710 for it with GETKEY command. Affected file silcd/command.c.
2712 * Removed the use_auto_addr variable from default config
2713 file since it was in wrong section. Affected file is
2716 * Fixed TOPIC_CHANGE notification to not route it when it
2717 was sent using silc_server_send_notify_to_channel function.
2718 Affected file silcd/command.c.
2720 * Fixed silc_server_send_notify_kicked to send the kicker's
2721 Client ID also, it was missing. Affected files are
2722 silcd/command.c, silcd/packet_send.[ch].
2724 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2726 * Do not save client history information in SERVER_SIGNOFF.
2727 Fixes the bug in normal server that it does not detect
2728 the client becoming valid after the server becomes back
2729 online. Affected file silcd/server_util.c.
2731 * Added `sock_error' field into the SilcSocketConnection
2732 context. When error occurs during socket operation (read
2733 or write) the error is saved. Added also new function
2734 silc_socket_get_error to return human readable socket error
2735 message. Affected files are lib/silcutil/silcsockconn.[ch],
2736 lib/silcutil/unix/silcunixsockconn.c, and
2737 lib/silcutil/win32/silcwin32sockconn.c.
2739 * The server now prints the socket error message in the
2740 signoff for client. Affected file silcd/server.c.
2742 * Fixed the `created' channel information sending from router
2743 to server in JOIN command. Checks now whether the channel
2744 really was created or not and set it according that.
2746 Fixed the JOIN command to use the client entry's current
2747 ID during the joining procedure instead of the one it sent
2748 in the command (it is checked though), since it can change
2749 between the packet processing and command processing, and
2750 would just case unnecessary pain in the client end. Affected
2751 file silcd/command.c.
2753 * Fixed a channel key payload sending to use correct channel
2754 ID when the server was forced to change the channel's ID by
2755 router. Router sent the key payload with the old Channel ID.
2756 Affected file silcd/packet_receive.c.
2758 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2760 * Call silc_server_save_channel_key only if the key payload
2761 was provided in the JOIN command's command reply. Affected
2762 file silcd/command_reply.c.
2764 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2766 * Fixed silc_mp_sizeinbase to return the value correctly with
2767 MPI. Affected file lib/silcmath/mp_mpi.c.
2769 * Fixed the stop_server signal to correctly stop the scheduler
2770 and gracefully stop the server when SIGTERM or SIGINT signals
2771 are received. Affected file silcd/silcd.c.
2773 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2775 * Simple handling of TERM and HUP signals. Also added some log
2776 flushing call around. Affected file is
2779 * Fixed small bugs in silclog.c. Now buffering output will take
2780 effect after 10 seconds since startup: This will ensure that
2781 no important startup messages are lost. Also output redirection
2782 will preserve original format ([Date] [Type] message).
2783 Affected file is lib/silcutil/silclog.c.
2785 * Added two options to the config file, in the logging section:
2786 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2787 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2789 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2791 * Do not print the warning about log files not being initialized
2792 more than once to avoid excess logging. Affected file is
2793 lib/silcutil/silclog.c.
2795 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2796 the SIM copying in make install in Makefile.am.pre.
2798 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2800 * Rewritten silclog APIs. Globally interesting changes follows:
2801 silc_log_set_files() changed to silc_log_set_file().
2802 silc_log_set_callbacks() changed to silc_log_set_callback().
2803 ROBOdoc documented silclog header file.
2804 SilcLogCb now returns bool to wether inihibit the default
2805 handler or not (to keep the old behaviour return always TRUE).
2806 The new APIs should also fix the problem of the
2807 silcd_error.log file that was written in the current directory.
2810 Log files streams will remain opened after silc_log_set_file()
2811 call, means less CPU usage notably on high traffic servers.
2812 File streams are now full buffered, and flushed to the disk
2813 every 5 minutes, lesses HD activity and CPU usage.
2814 Messages can be redirected, allowing admins to configure
2815 one single logfile for all server messages.
2816 the silc_log_quick global variable to activate fast-logging.
2817 Affected files lib/silcutil/silclog.[ch]
2819 * Changed some code to conform new silclog APIs. Affected
2820 files are doc/example_silcd.conf.in, silcd/server.c
2821 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2824 * Fixed a memory leak that could occur in some situations.
2825 Affected file silcd/serverconfig.c.
2827 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2829 * Added the silc_client_del_client to remove the client from
2830 all channels as well. Affected file lib/silcclient/idlist.c.
2832 * Fixed the client library to correctly remove the client
2833 from all channels when the client entry is being destroyed.
2834 Affected file lib/silcclient/client_notify.c, command.c.
2836 * Added auto-nicking support to the client library. If the
2837 applicatio now sets client->nickname it will be sent to the
2838 server after connecting by the library. This way for example
2839 SILCNICK (or IRCNICK) environment variables will have effect
2840 and always change the nickname automatically to whatever
2841 it is wanted. Affected file lib/silcclient/client.[ch].
2843 * Renamed silc_server_command_bad_chars to the
2844 silc_server_name_bad_chars and moved it to the
2845 silcd/server_util.[ch]. Added also new function
2846 silc_server_name_modify_bad to return nickname that
2847 includes bad characters as new nickname without those
2848 bad characters. This check and modify is now used in
2849 silc_server_new_client when the username is initially set
2850 as nickname, so it must be checked to be valid nickname.
2851 Affected file silcd/packet_receive.c.
2853 * The nickname length is now taken from the packet for real
2854 and not trusted to strlen() since it clearly can return
2855 wrong length for nickname including bad characters. This
2856 also applies to channel names. Affected file silcd/command.c.
2858 * Removed the lib/silcsilm/modules directory. Modules are now
2859 compiled into the lib/silcsim. Fixed the copying of the
2860 modules to follow symbolic links in Makefile.am.pre.
2862 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2864 * Fixed silc_string_regexify list creation. Fixes bugs with
2865 BAN and INVITE commands in server. The affected file is
2866 lib/silcutil/unix/silcunixutil.c.
2868 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2870 * Removed the command destructor entirely from the server's
2871 command and command reply routines. It is not needed, and
2872 its usage was buggy and caused crashes. Affected files are
2873 silcd/command[_reply].[ch].
2875 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2877 * Cancel protocol and NULL sock->protocol if timeout
2878 occurred during protocol. Affected file silcd/server.c.
2880 * Cancel protocol timeouts always before calling the final
2881 callback, to assure that after final callback is called
2882 no other state will be called for the protocol anymore.
2883 Affected file silcd/protocol.c.
2885 * Print error log if incoming connection configuration could
2886 not be found. Affected file silcd/server.c.
2888 * Fixed JOIN command to correctly save the founder mode
2889 to the client on normal SILC server, when the channel
2890 was created by the router. Affected file silcd/command.c.
2892 * Fixed LIST command (hopefully) to send correct reply
2893 packets. Affected file silcd/command.c.
2895 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2897 * The silc_packet_receive_process now returns FALSE if the
2898 read data was invalid packet, and TRUE if it was ok.
2900 The server now checks that if unauthenticated connection
2901 sends data and its processing fails the server will close
2902 the connection since it could be a malicious flooder.
2904 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2906 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2908 * Make sure the warning about error opening a log file is
2909 printed only once and not everytime it fails (produces
2910 too much useless log). Affected file lib/silcutil/silclog.c.
2912 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2914 * Made the silc_server_daemonise() function more readable.
2915 Affected file silcd/server.c.
2917 * Pid file is now optional, the user may comment it out from
2918 the config file. Removed define SILC_SERVER_PID_FILE, we
2919 don't need a default any longer. Affected file
2920 configure.in.pre, lib/Makefile.am.pre.
2922 * Make some use of the pid file. The server now dies at startup
2923 if it detects a valid pid file on his path. The server would
2924 die anyway in this circumstance, because of the bind() failure.
2925 Affected file silcd/silcd.c.
2927 * No longer compiling lib/dotconf.
2929 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2931 * Fixed JOIN command parsing not to crash. Affected file
2932 lib/silcclient/command.c.
2934 * Fied the NICK_CHANGE notify to add the new client entry
2935 even it is resolved. This removes an <[unknown]> nick
2936 thingy bug in the client. Affected file is
2937 lib/silcclient/client_notify.c.
2939 * Do not try to allocate 0 bytes (efence does not like it)
2940 in lib/silccore/silccomand.c when encoding payload.
2942 * Do not take IRCNICK as nickname in Irssi SILC client since
2943 it is not possible to set nickname before hand connecting
2944 the server (TODO has an entry about adding auto-nicking
2947 * Changed the silc_server_command_pending to check whether
2948 there already exists an pending entry with the specified
2949 command, command identifier and pending callback. This is
2950 to fix IDENTIFY and WHOIS related crashes that may register
2951 multiple pending commands with same identifier. Affected
2952 file silcd/command.c.
2954 * Fixed the server to reconnect to the router even if it
2955 was already reconnecting and EOF was received. This to
2956 fix a possibility that the server wouldn't ever try to
2957 auto-reconnect to the router. Affected file silcd/server.c.
2959 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2961 * Fixed the server's password authentication to use the
2962 length of the locally saved password, and not the one
2963 sent in the packet. Affected file silcd/protocol.c.
2965 * Fixed same password authentication problem in the
2966 Authentication Payload handling routines in
2967 lib/silccore/silcauth.c.
2969 * Yet another password authentication problem fixed with
2970 channel password handling in silcd/command.c.
2972 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2974 * If first character of string in silc_parse_userfqdn is '@'
2975 then do not parse it. Affected file is
2976 lib/silcutil/silcutil.c.
2978 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2980 * Fixed minor bug in IDENTIFY command reply sending, which
2981 caused various weird problems during JOIN when it was
2982 resolving names for users. Affected file silcd/command.c.
2984 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2986 * Fixed the IDENTIFY command reply sending to chech better valid
2987 clients. It was possible to send incomplete list of replies.
2988 Affected file silcd/command.c.
2990 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2992 * Added silc_client_command[s]_[un]register functions now to
2993 dynamically register the commands in client library. Removed
2994 the static table of commands. This allows the client library
2995 to call commands without causing the application to know about
2996 what commands library has called.
2998 Removed the INFO command reply kludge to detect when the command
2999 was called by library. Now library use its own command reply
3000 function for INFO command.
3002 Added function silc_client_command_call to call a command.
3003 Application can use it to call command, not access the structure
3006 Now all commands that are sent by the client library (not
3007 explicitly sent by application) use own command reply functions.
3009 Affected files around lib/silcclient/ and in
3010 irssi/src/silc/core/.
3012 * Fixed the WHOIS command reply sending to chech better valid
3013 clients. It was possible to send incomplete list of replies.
3015 Fixed the WHOIS and IDENTIFY to send the request to router
3016 if normal server did not do it and did not find any results.
3018 Affected file silcd/command.c.
3020 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3022 * Moved the internal data from SilcClient context into its
3023 own file, not accesible to application. Affected files
3024 lib/silcclient/client.h and lib/silcclient/client_internal.h,
3025 and other files in client library.
3027 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3029 * Added doc/examples installation target in Makefile.am.pre.
3032 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3034 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
3035 commands the found client entry will be removed from the
3036 cache, after notifying application about the error. Affected
3037 file lib/silcclient/command_reply.c.
3039 * Changed the /MSG to check for exact nickname user gave, and
3040 not let `nick' match `nick@host' if it is only one found. Now,
3041 user must type the exact nickname (like nick@host2) even if
3042 there are no more than one same nicks found. This is to avoid
3043 a possibility of sending nickname to wrong nickname since
3044 `nick' could match `nick@host'. Affected file is
3045 irssi/src/core/silc-servers.c.
3047 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3049 * Do not print "you are now server operator" or similar when
3050 giving /away command. Affected files are
3051 irssi/src/silc/core/client_ops.c, silc-servers.h.
3053 * Made the silc_server_command_pending_error_check to send
3054 the same command reply payload it received back to the
3055 original sender of the command. This way all arguments
3056 that was received by the server will be received by the
3057 client too. Affected file silcd/command.c.
3059 * Added the silc_idcache_add to return the created cache entry
3060 to a pointer. Affected file lib/silccore/silcidcache.[ch].
3062 * Add global clients to expire if they are not on any channel.
3063 This is because normal server will never know if they signoff
3064 if they are not on any channel. The cache expiry will take
3065 case of these entries. This is done by normal servers only.
3066 The affected files are silcd/command_reply.c,
3067 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
3069 * If server receives invalid ID notification for WHOIS or
3070 IDENTIFY and the ID exists in the lists, it is removed.
3071 Affected file silcd/command_reply.c.
3073 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
3074 in client then client entry that it matches is searched and
3075 the nickname is printed on the screen for user. Affected
3076 file irssi/src/silc/core/client_ops.c.
3078 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3080 * Use cache entry expire time in the LIST command reply to
3081 purge old entries from the cache after the LIST command
3082 reply has been received. This way we don't have non-existent
3083 entries in the cache for too long. Affected file is
3084 silcd/command_reply.c.
3086 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3088 * If we are normal server, and we've not resolved client info
3089 in WHOIS or IDENTIFY from router, and it is global client,
3090 we'll check whether it is on some channel. If it is not
3091 then we cannot be sure about its validity and will resolve it
3092 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
3093 file silcd/command.c.
3095 * Search channel by name (if possible) rather than by ID
3096 in IDENTIFY command's command reply. Affected file is
3097 silcd/command_reply.c.
3099 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3101 * Distribute to the channel passphrase in CMODE_CHANGE notify.
3102 Updated specs and implemented it. Affected file silcd/command.c,
3103 silcd/packet_send.c and silcd/packet_receive.c.
3105 * Implemented the <founder auth> payload handling in the JOIN
3106 command. If provided all conditions for channel joining
3107 except requirement to provide correct passphrase can be
3108 overrided by the channel founder. Updated the protocol specs.
3109 Affected file silcd/command.c.
3111 Added support for founder auth in JOIN command in client
3112 library. Fixed the parsing of the JOIN command now to support
3113 all options as they should be. The affected file is
3114 lib/silcclient/command.c.
3116 * Optimized the WHOIS and IDENTIFY commands to send the request
3117 to router only if it includes nicknames or other names. If
3118 they include only IDs then check the local cache first before
3119 routing. Affected file is silcd/command.c.
3121 * Added channels topic announcements. Affected file is
3122 silcd/packet_receive.c and silcd/server.c.
3124 * Fixed the silc_server_send_notify_topic_set to really destine
3125 the packet to channel. Affected file silcd/packet_send.c.
3127 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
3128 library. Affected file lib/silcclient/client_notify.c.

3150 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3152 * Update the client entry context in the ID cache after
3153 nick change. Affected file lib/silcclient/command.c.
3154 Fixes the CUMODE command when regaining founder privileges,
3155 and a little WHOIS problem.
3157 * Fixed silc_net_gethostbyname to correctly call the
3158 inet_ntop. Affected file lib/silcutil/silcnet.c.
3160 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3162 * Added IPv6 support checking to the configure.in.pre, added
3163 also --enable-ipv6 option to override the check. Affected
3164 file configure.in.pre.
3166 * The silc_thread_create now calls the start function
3167 directly if threads support is not compiled in. Removes
3168 ugly #ifdef's from generic code. Affected files are
3169 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
3171 * Added silc_net_gethostby[name/addr]_async to asynchronously

3190 * Fixed LIST command reply sending in server. Affected file
3193 * Server now sends the kicker's client ID in the KICK notify
3194 to the kicked client. Affected file silcd/command.c.
3196 * The client library now parses the kickers client ID and
3197 UI displays it. Affected files lib/silcclient/client_notify.c
3198 and irssi/src/silc/core/silc-channels.c, module-formats.c.
3200 * Made all payload parsing function prototypes consistent.
3201 They all take now const unsigned char * and uint32 pair as
3202 the payload data instead of SilcBuffer. Changes all around
3203 the source tree. Other unsigned char* -> const unsigned char*
3204 changes around the tree as well.
3206 * Optimized SFTP client and server packet sending not to
3207 allocate new buffer for each packet but to recycle the
3208 first allocated buffer. Affected files are
3209 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
3211 * Optimized the SFTP client to use SilcList instead of
3212 SilcDList for requests, because it is faster. Affected file
3213 is lib/silcsftp/sftp_client.c.
3215 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
3216 into lib/silccore/silcid.[ch].
3218 Renamed silcpayload.[ch] into silcargument.[ch].
3220 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3222 * If client entry is deleted with active key agreement
3223 session, abort the session.
3225 The silc_client_abort_key_agreement now calls the completion
3226 callback with new SILC_KEY_AGREEMENT_ABORTED status.
3228 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
3231 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3233 * Don't use __restrict in older GCC's. Affected file is
3234 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
3236 * silc_net_localhost now attempts to reverse lookup the
3237 IP/hostname. Affected file lib/silcutil/silcnet.c.
3239 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
3240 command. It can be used to gain founder privileges at
3241 the same time when joining the channel.
3243 Defined that the SILC_NOTIFY_TYPE_KICKED send the
3244 kicker's client ID as well. Updated protocol specs.
3246 Defined that the server must send SILC_COMMAND_IDENTIFY
3247 command reply with error status to client who sent
3248 private message with invalid client ID.
3250 Updated the protocol specification.
3252 * Added silc_server_send_command_reply to send any
3253 command reply. Affected file silcd/packet_send.[ch].
3255 * Added silc_id_payload_encode_data to encode ID payload
3256 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
3258 * The server now send IDENTIFY command reply with error
3259 status if client ID in private message is invalid. Affected
3260 file silcd/packet_receive.c.
3262 * Save the server key file with server's IP address in
3263 the filename instead of hostname. The affected file is
3264 irssi/src/silc/core/client_ops.c.
3266 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3268 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
3271 * Added libtool support for compiling shared objects in
3272 lib/silcsim. Affected file configure.in.pre and
3273 lib/silcsim/Makefile.am. Original patch by cras.
3275 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3277 * Pid file configuration, and server's config file fixes
3278 patch by toma. Updated CREDITS file.
3280 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3282 * Fixed silc_client_channel_message to not try to decrypt
3283 the message twice if it resolved the destination client
3284 information. This could cause of dropping one channel
3285 message. Affected file lib/silcclient/client_channel.c.
3287 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3289 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3290 lib/silcclient/client.c. This function is used when the SILC
3291 Client is run under some other scheduler, or event loop or
3292 main loop. On GUI applications, for example this may be
3293 desired to used to run the client under the GUI application's
3294 main loop. Typically the GUI application would register an
3295 idle task that calls this function multiple times in a second
3296 to quickly process the SILC specific data.
3298 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3300 * Fixed silc_server_drop() for dropping the supplementary
3301 groups as well, this could cause a security hole on some
3304 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3306 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
3309 * Write PID file after dropping privileges. Added -F option
3310 to run server on foreground. A patch by debolaz.
3311 Affected files silcd/server.c, silcd/silcd.c.
3313 * Fixed MOTD to return the MOTD file server name. Affected
3314 file silcd/command.c.
3316 * Added INFO command reply handling to the Irssi SILC Client.
3317 Affected file irssi/src/silc/core/client_ops.c.
3319 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3321 * Fixed the silc_idcache_list_* routines to really support
3322 the dynamic list. Fixes a crash. Affected file is
3323 lib/silccore/silcidcache.c.
3325 * Fixed the LIST command reply to really call LIST command's
3326 pending callbacks. Affected file silcd/command_reply.c.
3328 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3330 * Update conn->local_entry->nickname after giving NICK
3331 command. Affected file lib/silcclient/command.c.
3333 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3335 * Added the [pid] option to the silcd configuration file
3337 Affected files: serverconfig.[ch] and silcd.c
3339 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3341 * Save fingerprint in WHOIS command reply in server.
3342 Affected file silcd/command_reply.c.
3344 * Fixed NICK commands pending callback registration.
3345 Affected file lib/silcclient/command.c.
3347 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3349 * Use ++server->cmd_ident when sending commands in server,
3350 instead of random number. Affected file silcd/command.c.
3352 * Fixed GETKEY command reply to call actually GETKEY pending
3353 command callbacks. Affected file silcd/command_reply.c.
3355 * A bit stricter check for nicknames. Check for same nickname
3356 in NICK command also. Affected file silcd/command.c.
3358 * Do not call INFO command everytime client ID changes, only
3359 during first connecting. Affected file lib/silcclient/client.c.
3361 * Set the new nickname only after successful command reply for
3362 NICK command is returned by server. Affected file
3363 lib/silcclient/command.c.
3365 * Remove nicknames from nicklist during server_signoff notify.
3366 Should fix /NAMES bit more. The affected file is
3367 irssi/src/silc/core/silc-channels.c.
3369 * Added `fingerprint' field to the SilcIDListData in the
3370 silcd/idlist.h to hold the fingerprint of the client's
3373 Send the fingerprint of the client's public key in WHOIS
3376 Affected files silcd/command.c, and silcd/idlist.[ch].
3378 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3379 create fingerprint from given data.
3381 * Show the fingerprint of the client's public key in WHOIS.
3382 Affected files irssi/src/module-formats.[ch] and
3383 irssi/src/silc/core/client_ops.c.
3385 * Format the multiple same nicknames also during JOIN and
3386 NICK_CHANGE notifys. Affected file is
3387 lib/silcclient/client_notify.c.
3389 * Do not print error on screen for invalid private message
3390 payload since it can come if someone is sending private
3391 messages with wrong key. Affected file
3392 lib/silccore/silcprivate.c.
3394 * Fixed multiple concurrent /PING crash. Affected file
3395 lib/silcclient/command.c.
3397 * Changed the wrong ID encoding. All IP addresses must be
3398 in MSB first order in encoded format. They were encoded
3399 wrong and was in LSB format. Affected files are
3400 silcd/serverid.c, lib/silcutil/silcutil.c.
3402 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3404 * Call the `connect' client operation through the scheduler
3405 in case of error. Affected file lib/silcclient/client.c.
3407 * Call the `failure' client operation even if the error
3408 occurred locally during a protocol. Affected file is
3409 lib/silcclient/protocol.c.
3411 * Added support of sending LIST command to router from normal
3412 server. This way normal server can get list of all channels
3413 in the network too. Fixed the channel list sending in the
3414 server too. Affected files are silcd/command.c, and
3415 silcd/command_reply.[ch].
3417 * Added silc_server_update_channels_by_server and
3418 silc_server_remove_channels_by_server. They are used during
3419 disconnection of primary router and in backup router protocol.
3420 Affected file silcd/server_util.[ch], silcd/server.c and
3421 silcd/server_backup.c.
3423 * Fixed channel adding to global list in IDENTIFY command
3424 reply in server. Affected file silcd/command_reply.c.
3426 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3428 * If the incoming packet type is REKEY or REKEY_DONE process
3429 that packet always synchronously. Fixes yet another MAC
3430 failed error on slow (dialup) connections. Affected file
3431 lib/silcclient/client.c and silcd/server.c.
3433 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3435 * Call check_version SKE callback for initiator too. Affected
3436 file lib/silcske/silcske.c.
3438 * Implemented fix for security hole found in the SKE that was
3439 fixed in the specification few days back; the initiator's
3440 public key is now added to the HASH value computation.
3441 Added backwards support for the old way of doing it too, for
3442 old clients and old servers. Affected file is
3443 lib/silcske/silcske.c.
3445 * Enabled mutual authentication by default in SKE. If initiator
3446 is not providing mutual authentication the responder will
3447 force it. This will provide the proof of posession of the
3448 private key for responder. The affected files are
3449 lib/silcclient/protocol.c and silcd/protocol.c.
3451 * Do not cache anymore the server's public key during SKE.
3452 We do mutual authentication so the proof of posession of
3453 private key is done, and if the server is authenticated in
3454 conn auth protocol with public key we must have the public
3455 key already. Affected file silcd/protocol.c.
3457 * Added new global debug variable: silc_debug_hexdump. If
3458 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3459 file lib/silcutil/silclog.[ch].
3461 * Fixed compilation warning due to char * -> const char *.
3462 Affected files lib/silcutil/silcnet.h, and
3463 lib/silccore/silcauth.[ch].
3465 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3467 * Fixed CMODE command when new channel key was created. If
3468 the creation failed the old key was removed. Next time giving
3469 same command would crash the server since the old key was
3470 freed already. Affected file silcd/command.c.
3472 * Fixed the silc_server_announce_get_channels to not crash
3473 on reconnect. Affected file silcd/server.c.
3475 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3477 * Added silc_log_set_debug_string function to set a regex
3478 string to match for debug output. Only the function names,
3479 or filenames matching the given debug string is actually
3480 printed. This way it is possible to filter out those debug
3481 strings that user is not interested in.
3483 Fixed a bug in silc_string_regexify.
3485 Affected files lib/silcutil/silclog.[ch], and
3486 lib/silcutil/unix/silcunixutil.c.
3488 * Changed the -d options in both server and Irssi SILC client
3489 to take the debug string as argument. Affected files
3490 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3492 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3494 * Added silc_hash_babbleprint to create a Bubble Babble
3495 Encoded fingerprint. The encoding is developed by Antti
3496 Huima (draft-huima-babble-01.txt), and it creates human
3497 readable strings out of binary data. Affected file
3498 lib/silccrypt/silchash.[ch].
3500 * Print the babble print now in addition of fingerprint as well
3501 in Irssi SILC client. Affected files are
3502 irssi/src/fe-common/silc/module-formats.[ch],
3503 irssi/src/fe-common/silc/core/client_ops.c.
3505 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3507 * Fixed a security problem found in SKE. The initiator's
3508 public key too is now added to the HASH hash value creation
3509 which is signed by the responder to create the SIGN value.
3510 This will prevent anyone in the middle to lie to the responder
3511 about the initiator's public key. If this is done now, the
3512 man in the middle will get caught. Updated the protocol
3515 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3517 * Better installation directory handling. Configure module
3518 paths and other paths automatically to example_silc* files
3519 in doc/. A patch by toma.
3521 * Fixed compiler warning from MPI library, and from SILC RNG.
3524 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3525 It can be configured with ./configure. A patch by toma.
3527 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3529 * Find correct make to use in prepare-clean. A patch by
3530 toma. Affected file prepare-clean.
3532 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3534 * Added irssi variables use_auto_addr, auto_bind_ip,
3535 auto_bind_port and auto_public_ip.
3537 * Changed the interface for silc_client_send_key_agreement
3538 in lib/silcclient/silcapi.h
3542 irssi/src/silc/core/silc-core.c
3544 lib/silcclient/silcapi.h
3545 irssi/src/silc/core/silc-channels.c
3546 lib/silcclient/client_keyagr.c
3549 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3551 * Added silc_pkcs_public_key_compare to compare two
3552 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3554 * Check that the client who set the founder mode on the
3555 channel is the same client that is giving the founder
3556 mode to itself. It is done by comparing the saved public
3557 key (it is saved even in the authentication is passphrase).
3558 Affected file silcd/command.c.
3560 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3562 * Do not process packet for disconnected socket connection.
3563 Affected file lib/silccore/silcpacket.c.
3565 * Process the DISCONNECT packet through scheduler in the
3566 client library. Affected file lib/silcclient/client.c.
3568 * Fixed the silc_client_packet_parse to not to increase
3569 the packet sequence number if the conn->sock and the
3570 current socket connection is not same. This can happen
3571 for example during key agreement when the conn includes
3572 multiple socket connections (listeners). Affected file
3573 lib/silcclient/client.c.
3575 * The sender of the file transfer request now provides also
3576 the pointer (listener) for the key exchange protocol. If
3577 the listener cannot be created then it sends empty key
3578 agreement and lets the receiver provide the listener.
3580 Added `local_ip' and `local_port' arguments to the
3581 silc_client_file_send. If they are provided they are used,
3582 if not then it will attempt to find local IP address, if
3583 not found or bind fails then the remote client will provide
3586 Affected files are lib/silcclient/client_ftp.c and
3587 lib/silcclient/silcapi.h.
3589 * Extended the FILE SEND command to support defining the
3590 local IP and port for key exchange listener. They are
3591 optional. Affected file irssi/src/silc/core/silc-servers.c.
3593 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3595 * Defined to WHOIS command reply the sending of fingerprint
3596 of the client's public key (if the proof of posession of the
3597 corresponding private key is verified by the server).
3598 Updated to the protocol specification.
3600 * Added support of receiving the client's public key's
3601 fingerprint in command reply in client library. Affected
3602 file is lib/silcclient/command_reply.c, and
3603 lib/silcclient/idlist.[ch].
3605 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3607 * Do not send over 128 chars long nickname to the server
3608 in NICK command. Affected file lib/silcclient/command.c.
3610 * Do not send over 256 chars long channel names to the server
3611 in JOIN command. Affected file lib/silcclient/command.c.
3613 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3615 * Assure that silc_server_close_connection cannot be called
3616 twice for same socket context. Affected file is
3619 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3621 * Send error message to application if opening file for
3622 writing during file transfer fails. Affected file is
3623 lib/silcclient/client_ftp.c.
3625 Remove all file transfer sessions for a client that we're
3626 removing from ID cache.
3628 Affected file is lib/silcclient/client_ftp.c.
3630 * Fixed silc_net_addr2bin to return correct address. Affected
3631 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3633 * Fixed file transfer session removing on signoff notify.
3634 Affected file irssi/src/silc/core/silc-servers.c.
3636 * Added the SilcClientFileError to be returned in the monitor
3637 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3638 Affected file lib/silcclient/silcapi.h.
3640 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3642 * Fixed a crash in silc_client_ftp_free_sessions and
3643 silc_client_ftp_session_free_client. Affected file
3644 lib/silcclient/client_ftp.c.
3646 * Added `disabled' field in the SilcChannelEntry in the server
3647 to indicate if the server entry is disabled. Affected file
3648 silcd/idlist.h, silcd/command[_reply].c.
3650 * SILC server adds now /var/run/silcd.pid everytime it is
3651 started. Affected file silcd/silcd.c.
3653 * Added silc_server_packet_send_clients to send a packet to
3654 the provided table of client entries. Affected file
3655 silcd/packet_send.[ch].
3657 * Fixed a crash in client resolving in client_prvmsg.c in
3658 client library. Affected file lib/silcclient/client_prvmsg.c.
3660 * Do not actually remove the client directly from ID cache
3661 during SERVER_SIGNOFF, but invalidate it. This way we
3662 preserve the WHOWAS info for the client. Affected file
3663 silcd/server_util.c.
3665 * Fixed SERVER_SIGNOFF notify handling in the server. The
3666 server is now able to process incoming SERVER_SIGNOFF notify
3667 for a server that it doesn't even know about. It will remove
3668 the clients provided in the notify. Affected file
3669 silcd/packet_receive.c.
3671 * Check for partial packet in data queue after every packet that
3672 was found from the queue. Return and wait for more data if
3673 there is partial data in queue. Affected file is
3674 lib/silccore/silcpacket.c.
3676 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

3685 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3687 * Added better monitor of file transfers. It now monitors
3688 key agreement protocol during the file transfer too. Added
3689 error reporting too. Affected files
3690 irssi/src/silc/core/silc-servers.c,
3691 irssi/src/fe-common/silc/module-formats.[ch].
3693 * Wrote a help file for FILE command.
3695 * Added silc_rng_global_get_byte_fast to get not-so-secure
3696 random data as fast as possible. Random data is read from
3697 /dev/urandom if available and from the SILC RNG if not
3698 available. It is used in padding generation. Affected file
3699 lib/silccrypt/silcrng.[ch].
3701 * All packets in client library are now processed synchronously.
3702 Optimized packet processing a lot. Affected file
3703 lib/silcclient/client.c.

3710 if make install is given. Affected files: all Makefile.am's.
3712 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3714 * Assure that silc_client_notify_by_server_resolve does not
3715 resolve the client information multiple times. If it cannot
3716 be found by the first it cannot be found at all. Affected
3717 file lib/silcclient/client_notify.c.
3719 * Fixed WHOWAS command reply calling. Affected file
3720 lib/silcclient/command_reply.c.
3722 * Removed all references to silc_idlist_get_client from the
3723 Irssi SILC client since that call is internal call used by
3724 the library. The Irssi SILC client will use now client
3725 retrieval functions found in silcapi.h.
3727 * Fixed a bug in resolving nickname info before sending
3728 private message. It used freed memory. Affected file
3729 irssi/src/silc/core/silc-servers.c.
3731 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3733 * Assure my_channels statistics cannot go negative in server.
3734 Affected files silcd/server.c, silcd/server_util.c.

3750 * Added silc_net_localip to return local host's IP address.
3751 Affected file lib/silcutil/silcnet.[ch].
3753 * If key exchange or rekey protocol is active for a connection
3754 parse all packets syncronously since there might be packets
3755 in packet queue that we are not able to process without first
3756 processing packets before them. Affected file silcd/server,
3757 lib/silcclient/client.c.
3759 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3760 whether library should continue processing the packet.
3761 Affected file lib/silccore/silcpacket.h.

3807 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3808 is incomplete and is being resolved, it won't be resolved
3811 Make sure also that USERS command reply does not resolve
3812 twice information. Affected file is
3813 lib/silcclient/command_reply.c.
3815 Make sure that silc_client_get_clients_by_list does not
3816 resolve twice same information.
3818 * Check for valid client->id in the silc_server_free_client_data.
3819 Affected file silcd/server.c.
3821 * Fixed /GETKEY nick@server not to crash if the server entry
3822 is not found. Affected file lib/silcclient/command.c.
3824 * Fixed the silc_server_check_cmode_rights to check the
3825 requested modes correctly. Affected file silcd/command.c.

3830 Affected file silcd/command.c.
3832 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3834 * Call the silc_server_udpate_servers_by_server in the
3835 primary router that comes back online in the backup resuming
3836 protocol. Otherwise it routes packets wrong. Affected file
3837 silcd/server_util.[ch], silcd/server_backup.c.
3839 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3841 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3842 lib/silcutil/silcbuffmt.[ch].
3844 * Redefined the SILC packet header to include the padding
3845 length. Affected file lib/silccore/silcpacket.[ch].
3847 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3848 length for maximum padding up to 128 bytes). Affected
3849 file lib/silccore/silcpacket.h.
3851 * Removed all backwards support for old 0.5.x MAC thingies.
3852 The SILC packet header change makes it impossible to be
3853 backwards compatible.
3855 * Send the ENDING packet with timeout in the backup resuming
3856 protocol. This is to assure that all routers has connected
3857 to the primary router. Affected file silcd/server_backup.c.
3859 * Changed the RNG to take the first IV from random data. It
3860 used to take it from zero actually. Changed the RNG also
3861 to use /dev/urandom during session. /dev/random is used
3862 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3864 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3866 * Changed the SILC packet header to have the first two bytes
3867 (the packet length) encrypted. Affected files aroung the
3868 code tree, lib/silccore/silcpacket.[ch]. Removed the
3869 SilcPacketCheckDecrypt callback. It is not needed anymore
3870 since the silc_packet_receive_process will determine now
3871 whether the packet is normal or special.
3873 * Implemented the unidirectional MAC keys. Affected files
3874 lib/silcske/silcske.c, silcd/protocol.c and
3875 lib/silcclient/protocol.c.
3877 * Implemented the packet sequence number to the MAC computation.
3878 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3879 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3880 lib/silcclient/protocol.c.
3882 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3884 * Allow backup router to announce servers. All servers
3885 announced by backup router are added to the global list
3886 automatically. Update hte server's socket to our primary
3887 router also when backup router announces a server.
3888 Affected file silcd/packet_receive.c.
3890 * Do not update the client->router in the function
3891 silc_server_udpate_clients_by_server if the client is on
3892 global list. We might fail to find any specific server
3893 for locally connected clients and local cell clients. They
3894 should still use the `from' and not `to' as client->router.
3895 This fixes backup router resuming protocol. Affected file
3896 silcd/server_util.c.
3898 * Decrease channel statistics count only if the channel
3899 deletion worked. Affected files are silcd/server.c and
3900 silcd/server_util.c.
3902 * Added silc_server_update_servers_by_server to update origin
3903 of all server entries. Used during backup router protocol.
3904 Affected files silcd/server_util.[ch], silcd/server.c. and
3905 silcd/backup_router.c.
3907 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3908 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3909 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3910 lib/silccrypt/silchmac.c.
3912 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3914 * Assure that router cannot reroute the same channel message
3915 to the sender. Affected file silcd/packet_receive.c.
3917 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3919 * Made better checks that the channel message is not sent
3920 to the router it came from. Affected file is
3921 silcd/packet_send.c. Fixed memory leak too.
3923 * Announce informations for incoming router connection, but
3924 only after checking if it is replaced by backup router.
3925 Affected file silcd/packet_receive.c.
3927 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3929 * Fixed the backup resuming protocol to work in multiple
3930 router environment. Affected file silcd/server_backup.c.
3932 * Route packet only to one router in the function
3933 silc_server_packet_send_to_channel. Affected file is
3934 silcd/packet_send.c.
3936 * Fixed silc_server_send_notify_dest to set the broadcast
3937 flag. Fixed the silc_server_send_notify_topic to actually
3938 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3939 Affected file silcd/packet_send.c.
3941 * Changed the SFTP Filesystem interface. Changed the
3942 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3943 the filesystem operation function. The SilcSFTPFilesystem
3944 is now a context that is allocated by all filesystem allocation
3945 functions and it already includes the operations structure
3946 and filesystem specific context. It is given as argument
3947 now to the silc_sftp_server_start. This made the interface
3948 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3949 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3951 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3953 * Changed the backup router adding and getting interfaces
3954 in the server. The router that will be replaced by the
3955 specified backup router is now sent as argument. Affected
3956 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3959 * Added silc_net_addr2bin_ne to return the binary form of
3960 the IP address in network byte order. Affected files
3961 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3963 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3965 * Check for existing server ID in silc_server_new_server
3966 and in silc_server_connect_to_router_final and remove the
3967 old entry if it exists. Affected file silcd/packet_receive.c,
3970 * Send the channel message always to only one router, either
3971 in upstream or downstream. Affected file is
3972 silcd/packet_send.c.
3974 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3976 * Wrote the definition of the backup resuming protocol to the
3977 protocol specification.
3979 * Removed one redundant channel key generation from normal
3980 server during joining procedure. Removed one redundant
3981 channel key sending from server to router during joining
3982 procedure. Affected file silcd/command.c.
3984 * Made minor bugfixes to the backup router resuming protocol.
3985 Affected file silcd/server_backup.c, server.c.

3990 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3993 * Implemented the backup resuming protocol that is used to
3994 resume the primary router position in the cell after the
3995 primary router comes back online. Affected files
3996 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3997 and silcd/server_util.[ch].
3999 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4001 * Sleep two (2) seconds after sending QUIT command to server.
4002 Affected file lib/silcclient/command.c.
4004 * Assure that if outgoing data buffer is pending do not force
4005 send any data. Affected file silcd/packet_send.c.
4007 * Assure that if outgoing data buffer is pending do not force
4008 send any data. Affected file lib/silcclient/client.c.
4010 * Implemented the backup router support when the primary router
4011 goes down. The servers and routers can now use the backup
4012 router as new primary router without loosing connectivity.
4014 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4016 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
4017 in the server to indicate disabled entry. All data read
4018 from the connection will be ignored and no data is sent
4019 for entry that is disabled. Affected files are
4020 silcd/idlist.h, silcd/server.c.
4022 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4024 * Created SFTP client and server test programs in the
4025 lib/silcsftp/tests directory.
4027 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4029 * Implemented memory filesystem (virtual filesystem) for
4030 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
4033 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4035 * Implemented the SFTP (SSH File Transfer Protocol) to the
4036 lib/silcsftp. It includes SFTP client and SFTP server
4039 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4041 * Moved lib/silccore/silcprotocol.[ch] to the
4042 lib/silcutil library.
4044 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
4045 take variable argument list pointer as argument. Affected
4046 file lib/silcutil/silcbuffmt.[ch].
4048 * Added silc_buffer_set function that is used to set data
4049 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
4050 Affected file lib/silcutil/silcbuffer.h.
4052 * Changed various routines in the core library to use the new
4053 silc_buffer_set instead of allocating new buffer only for
4056 * Added 64-bit value formatting and unformatting support to the
4057 silc_buffer_[un]format routines. Affected file is
4058 lib/silcutil/silcbuffmt.[ch].
4060 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
4061 to includes/bitmove.h.
4063 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4065 * Fixed channel user mode saving in client library. Affected
4066 file lib/silcclient/command[_reply].c.
4068 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4070 * Defined the file transfer to the SILC Protocol. Added
4071 new packet type SILC_PACKET_FTP and defined File Transfer
4072 Payload. The mandatory file transfer protocol is SFTP
4073 (SSH File Transfer Protocol). Affected file in addition
4074 of the internet draft is lib/silccore/silcpacket.h.
4076 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
4077 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
4078 is used as part of backup router protocol when the primary
4079 router of the cell is back online and wishes to resume
4080 the position as primary router.
4082 * Redefined the MAC generation keys in the protocol. The
4083 same key is not used anymore in both direction. Both
4084 direction will now use different keys for sending and
4085 receiving. This fixes a potential security flaw. This
4086 change causes incompatibilities in the protocol.
4088 * Redefined also the MAC computation from the packet.
4089 An packet sequence number is now added to the MAC
4090 computation. This prevents possible replay attacks against
4091 the protocol. This change too causes incompatibilities
4094 Added `sequence' field to the SilcPacketContext to hold
4095 the current sequence number for the packet.
4097 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4099 * Added `created' field to the SilcIDListData in the file
4100 silcd/idlist.h to indicate the time when the entry was
4103 * Added `created' field to the SilcChannelEntry too. Affected
4104 file silcd/idlist.h.
4106 * Added `creation_time' aguments to all the announcement functions
4107 in the server. If it is provided then only the entries that
4108 was created after the provided time frame are actually
4109 announced. Affected file silcd/server.[ch].
4111 * The protocol says that the Channel ID's IP address must be
4112 based on the router's IP address. Added check for this in
4113 the silc_server_new_channel when processing incoming New Channel
4114 Payload. Affected file silcd/packet_receive.c.
4116 * Print out the correct version with --version in SILC client.
4117 Affected file irssi/src/silc/core/silc-core.c.
4119 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4121 * Fixed WHOWAS command to check for completnes of the client
4122 entry always, not just when the command is coming from client.
4123 Affected file silcd/command.c.
4125 * Added new function silc_server_packet_queue_purge to purge the
4126 outgoing data queue to the network. After the function returns
4127 it is guaranteed that the outgoing packet queue is empty.
4128 Affected file silcd/packet_send.[ch].
4130 * Purge the outgoing packet queue in the rekey protocol's final
4131 callback to assure that all rekey packets go to the network
4132 before quitting the protocol. Affected file silcd/server.c.
4134 * Added silc_client_packet_queue_parse as similar function as
4135 in server to the client library. The affected file is
4136 lib/silcclient/client.c.
4138 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4140 * Splitted silcd/server.c and created silcd/server_util.[ch]
4141 for utility functions.
4143 * Added new socket flag SILC_SF_DISABLED to indicate that the
4144 connection is open but nothing can be sent to or received from
4145 the connection. Affected file lib/silcutil/silsockconn.[ch].
4146 The checking for disabled socket is checked in the low level
4147 silc_socket_write and silc_socket_read functions.
4149 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4151 * Allow only nicknames and channel names that fits into the
4152 7-bit unsigned char ASCII set. Affected file silcd/command.c.
4154 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4156 * When processing JOIN command reply in server check that if
4157 the channel exists in our global list we'll move it the local
4158 list. Affected file silcd/command_reply.c.
4160 * Fixed the check whether client is joined on the channel already
4161 in JOIN command. Affected file lib/silcclient/command.c.
4163 * Fixed the JOIN command reply to check whether the channel
4164 already exists. Affected file lib/silcclient/command_reply.c.
4166 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4168 * Added silc_ske_status_string to map the SKE error numbers
4169 to readable strings. The affected files are
4170 lib/silcske/silcske[_status].[ch].
4172 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4174 * Do not show the private channels on the WHOIS channel list
4175 as it is not allowed by the protocol. The affected file is
4178 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4180 * Assure that the packet length digged from the actual packet
4181 is something sensible in the silc_packet_decrypt_rest_special
4182 in lib/silccrypt/silcpacket.c.
4184 * Free and NULL the allocated pointer in silc_hmac_alloc if
4185 the HMAC allocation fails. The affected file is
4186 lib/silccrypt/silchmac.c.
4188 * Print the selected security properties to the log files in
4189 the server. Affected file silcd/protocol.c.
4191 * Add SKE's reference counter even if calling the completion
4192 callback manually. Otherwise it goes negative, although it
4193 does not cause any problems. The affected file is
4194 lib/silcske/silcske.c.
4196 * Remove the client entry with short timeout after giving the
4197 KILL command. Affected file lib/silcclient/command.c.
4199 * Fixed to send error reply in WHOIS and IDENTIFY commands in
4200 case all found clients are already disconnected (WHOWAS would
4201 found them) in the server. Affected file silcd/command.c.
4203 * Update the last_receive (time of last data received) to be
4204 updated only when received private or channel message so that
4205 the idle time showed in WHOIS makes more sense.
4207 * Added boolean field `valid' in to the SilcClientEntry in the
4208 client library to indicate whether the entry is valid or not.
4209 This fixes the nickname change bug on channel when changing
4210 the nickname to be same than the old (like nick to Nick) the
4211 nickname formatter doesn't set the new nick anymore to Nick@host.
4212 Affected file lib/silcclient/idlist.[ch].
4214 * Now actually fixed the nickname changing on disconnection.
4215 Added new function silc_change_nick to the Irssi SILC Client.
4216 Affected file irssi/src/silc/core/client_ops.c,
4217 irssi/src/silc/core/silc-nicklist.[ch].
4219 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4221 * Check that the public key exists in the GETKEY command before
4222 trying to encode it. Affected file silcd/command.c.
4224 * Print some notifications on received public keys with GETKEY
4225 command in the Irssi SILC Client. Affected files are
4226 irssi/src/fe-common/silc/module-formats.[ch],
4227 irssi/src/silc/core/client_ops.c.
4229 * Use IDENTIFY command to resolve the server information in the
4230 GETKEY command instead of INFO command. Affected file
4231 lib/silcclient/command.c.
4233 * All command reply functions in the client library now calls
4234 the pending command reply callbacks even if an error has
4235 occurred. The server has done this a long time and now it was
4236 time to move the client library to this as well. Now all
4237 errors can be delivered back to the pending command reply
4238 callbacks if necessary. Affected files are
4239 lib/silcclient/command[_reply].[ch].
4241 * Change the nickname on disconnection back to the username
4242 because in reconnect the server will enforce it to it anyway.
4243 Affected file irssi/src/silc/core/silc-servers.c.
4245 * Fixed a config file parsing bug in the Irssi SILC client.
4246 Affected file irssi/src/silc/core/clientconfig.c.
4248 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4250 * When printing the channel mode on JOIN, verify that the
4251 channel key and channel's HMAC are valid. Affected file
4252 irssi/src/silc/core/client_ops.c.
4254 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4256 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
4257 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
4258 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
4260 * Removed channel key rekey task deleting from the function
4261 silc_server_save_channel_key. Affected file silcd/server.c.
4262 Added explicit timeout task context instead that is used to
4263 delete the task if we are registering a new task before the
4264 new task has elapsed.
4266 * When channel key rekey occurs the client library now saves
4267 the old channel key for a short period of time (10 seconds) and
4268 is able to use it in case some is still sending channel
4269 messages encrypted with the old key after the rekey. Affected
4270 file lib/silcclient/[idlist.h|client_channel.c].
4272 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4274 * Added check to the silc_server_new_id_real to not accept
4275 new ID if it is the sender's own ID. Affected file is
4276 silcd/packet_receive.c.
4278 * Assure that we do not announce ourself or the one we've
4279 sending our announcements when we're router and are announcing
4280 servers to our primary router. Affected file silcd/server.c.
4282 * Fixed silc_server_command_identify_check_client to assemble
4283 correct WHOIS packet. It send corrupted WHOIS packet and
4284 caused problem with router to router connections. Affected
4285 file silcd/command.c.
4287 Fixed also silc_server_command_whois_check the same way
4288 as for the IDENTIFY command.
4290 * Added new SilcIDListStatus to the server in the SilcIDListData
4291 structure. The status now includes the current status of
4292 the entry (like registered, resolved etc.). Affected file
4293 silcd/idlist.[ch]. Defined a bunch of different status types
4294 as well. This replaced the old boolean registered field as well.
4296 Added resolve_cmd_ident field to the SilcClientEntry structure
4297 too so that if the entry is for example being resolved so
4298 another command may attach to the same pending command reply
4299 without requiring to resolve the same entry again. This concept
4300 should optimize the WHOIS and the IDENTIFY resolving under
4301 heavy load by taking away unnecessary resolving for entries
4302 that are being resolved already.
4304 Added support for adding multiple pending commands for one
4305 command idenfier. Affected file silcd/command[_reply].[ch].
4307 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4308 before deleting the data. Otherwise the hash table will have
4309 freed data in comparison functions. Affected file is
4310 silcd/command_reply.c.
4312 * Fixed silc_idlist_replace_client_id to add the new entry to
4313 the cache with NULL nickname. Otherwise there will be invalid
4314 memory as the nickname after the nickname is freed. Affected
4315 file silcd/packet_receive.c.
4317 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4318 saved into wrong slots because the previous number of entries
4319 was not taken into account. Affected file silcd/idlist.c.
4320 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4322 * If we are router and we receive JOIN notify to a channel that
4323 does not have any users then notified client is marked as the
4324 channel founder, as it is it. The affected file is
4325 silcd/packet_receive.c
4327 * Added to the extended hash table API's table_del_*ext functions
4328 the destructor as argument too, so that the caller can decide
4329 which destructor to use or whether to use destructor at all.
4330 Affected file lib/silcutil/silchashtable.[ch].
4332 * Fixed ID Cache purging. It actually deleted the entries from
4333 the hash table after the data was freed. The hash table ended
4334 up comparing freed memory. The affected file is
4335 lib/silccore/silcidcache.c.
4337 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4339 * Fixed Irssi SILC client's KILL command's HELP syntax.
4341 * The USERS command now resolves the detailed user information
4342 if the userinfo field is missing. Affected file is
4343 lib/silcclient/command_reply.c.
4345 * Do not print error in silc_file_read if the read file does
4346 not exist. Just silently return NULL. Affected file is
4347 lib/silcutil/silcutil.c.
4349 * Fixed the silc_log_output to not wine about NULL filename
4350 and to not create some bogus " " filename. Affected file is
4351 lib/silcutil/silclog.c.
4353 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4355 * Fixed various printing bugs on the user interface in the
4356 Irssi SILC Client. Minor changes that were forgotten from
4359 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4361 * Fixed the configure.in.pre and the compilation and distribution
4362 environment to support the new autoconf 2.52. That version is
4363 now required to compile the CVS trunk.
4365 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4367 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4368 to generally parse user@fqdn format strings. Affected file
4369 lib/silcutil/silcutil.c.
4371 * Added nickname_format and nickname_force_format fields to the
4372 SilcClientParams structure. The first one defines the format
4373 for the nicknames that the library will enforce if the receives
4374 multiple same nicknames. The second one is boolean value and
4375 can be used to force the library to always enforce the format
4376 to the nicknames regardles whether there are multiple nicknames
4377 or not. This configurable formatting was employed to flexibly
4378 support accessing multiple nicknames from the user interface.
4379 The userinterface can now set the nicknames to what ever format
4380 they prefer. Affected file lib/silcclient/silcapi.h.
4382 Added function silc_client_nickname_format to the file
4383 lib/silcclient/idlist.c. It performs the nickname formatting.
4385 Added new field `hostname´ to the SilcClientEntry context.
4386 It holds the hostname of the client. Affected file is
4387 lib/silcclient/idlist.h.
4389 * Irssi SILC Client sets the nicknames in nick@hostn format.
4390 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4391 irssi/src/silc/core/silc-core.c.
4393 The WHOIS printing now also shows both the real nickname and
4394 the formatted nickname so that user knows how to access the
4395 user if there are multiple same nicknames cached. Affected
4396 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4397 printing formatting too to take the hostname now as a separate
4398 argument. The Affected file is
4399 irssi/src/fe-common/silc/modules-formats.[ch].
4401 * Changed the silc_client_get_clients_local to accept the formatted
4402 nickname as argument. It accepts the real nickname too but the
4403 formatted nickname can be used to find the true entry from
4404 multiple entries. Affected file lib/silcclient/silcapi.h and
4405 lib/silcclient/idlist.c.
4407 * Added nickname_format_parse field to the SilcClientParams.
4408 It is a callback function provided by the application to parse
4409 the nickname out of the formatted nickname string. The library
4410 calls it to get the nickname from the formatted string. Since
4411 the application generally knows better the format of the nickname
4412 string it parses it instead of the library, even though library
4413 encodes the formatted string. If the callback function is not
4414 provided then the library will use the string as is. The
4415 affected file is lib/silcclient/silcapi.h.
4417 * All the nickname strings passed to the client library in
4418 commands are now expected to be formatted nickname strings.
4419 If the command does not support the formatted nickname string
4420 it will assume that the sent string is the actual nickname.
4421 Affected file lib/silcclient/command.c.
4423 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4425 * Added public key authentication support to OPER and SILCOPER
4426 commands in the client library. Affected file is
4427 lib/silcclient/command.c.
4429 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4431 * Changed the get_auth_methdod client operation to be asynchronous.
4432 It can be async if the application resolves the authentication
4433 method from the server during the negotiation. Added new
4434 SilcGetAuthMeth completion callback that the application will
4435 call after resolving the authentication method.
4437 Added function silc_client_request_authentication_method that
4438 the application can use to resolve the authentication method
4439 from the server. Added also SilcConnectionAuthRequest callback
4440 that the library will call after the server has replied. The
4441 application can call this function if it does not know the
4442 current authentication method.
4444 Affected files are lib/silcclient/client.c and
4445 lib/silcclient/silcapi.h.
4447 * The Irssi SILC client now automatically resolves the authentication
4448 method incase any configuration information is not present (and
4449 currently there never is). The affected file is
4450 irssi/src/silc/core/client_ops.c.
4452 * Fixed public key authentication from the client library.
4453 Affected file lib/silcclient/protocol.c. Changed also the
4454 protocol specification about the public key authentication in
4455 the connection authentication protocol. The actual data to be
4456 signed is now computed with a hash function before signing.
4458 * Fixed the public key authentication from the server as well.
4459 Affected file silcd/protocol.c.
4461 * Removed the mlock()'s from the memory allocation routines.
4462 Affected file lib/silcutil/silcmemory.c. The ./configure does
4463 not check anymore for the mlock(). Affected file is
4466 * Fixed USERS command in server to allow the execution of the
4467 command for private and secret channels if the client sending
4468 the command is on the channel. Affected file silcd/command.c.
4470 * Fixed silc_client_get_clients_local to return the clients
4471 count correctly. It could return wrong value. Affected file
4472 lib/silcclient/idlist.c.
4474 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4476 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4477 types. The assembler optimizations seemed not to like 64-bit
4478 data types. The assmebler optimizations thus are now enabled
4479 also for BSD systems as opposed to only enable them for Linux.
4481 * Do not check for threads at all on BSD systems. Affected
4482 file configure.in.pre.
4484 * Removed -n and -h options from the Irssi SILC Client since
4485 they are not used in silc.
4487 * Fixed the prime generation to assure that the first digit
4488 of the generated random number is not zero since our conversion
4489 routines does not like number strings that starts with zero
4490 digit. If zero digit is seen the random number is regenerated.
4491 This caused some corrupted RSA keys when the zero first digit
4492 was met. Affected file lib/silcmath/silcprimegen.c.
4494 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4496 * Fixed WIN32 configuration in the ./configure script.
4497 Fixed to include xti.h on environments that has it.
4498 Patches by Carsten Ilchmann and andrew.
4500 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4502 * Changed the silc_id_create_client_id to be collision
4503 resistant. It is now assured that there cannot be created
4504 two same client ID's. I suspect that some weird bugs in
4505 the server were actually caused by duplicate Client IDs.
4506 Affected file silcd/serverid.[ch]. A router receiving
4507 new ID now also assures and informs the sending server
4508 if the ID caused collision.
4510 * Changed the silc_id_create_channel_id to also assure that
4511 there are no collisions.
4513 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4515 * Statement about ignoring the Mutual Authentication flag when
4516 performing rekey with PFS was a bit misleading. It is ignored
4517 if it was set in the initial negotiation, it cannot be even
4518 set in the rekey. Fixed in the ke-auth draft. Started the
4519 new versions of the protocol drafts in the doc/.
4521 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4523 * Fixed a bug in silc_client_command_identify_save when saving
4524 new channel information. The channel name was no duplicated
4525 and caused crash on exit. Affected file is
4526 lib/silcclient/command_reply.c.
4528 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4530 * Fixed the getkey command handling in the server. Send just
4531 empty OK reply to the sender if the key could not be fetched
4532 (but everything else was ok, like the key just was not available).
4533 Changed the public key parameter to optional in the protocol
4534 specs so that empty OK reply can be sent. Affected file
4537 Added a message to Irssi SILC client to tell to user if the
4538 server did not return a public key.
4540 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4542 * Fixed a channel key regeneration bug. It registered new
4543 timeout tasks exponentially until all system resources were
4544 used. Affected file silcd/server.c.
4546 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4548 * Added the SILC Document generator to the scripts/silcdoc.
4549 It can be used to generate the Toolkit Reference Manual out
4550 of the source tree. Internally it will also use the RoboDoc
4551 generator now imported in util/robodoc.
4553 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4555 * Added couple of return's in rekey protocol if error orccurred
4556 during the protocol. The execution must be terminated.
4557 Affected file silcd/protocol.c. Also, terminate the protocol
4558 always with timeout.
4560 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4562 * The client's Client ID was created initally from the wrong
4563 nickname (it could have been in format nick@host) in the
4564 silc_server_new_client. Affected file silcd/packet_receive.c
4566 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4568 * Added some SILC_LOG_ERROR's to various error conditions
4569 if client could not be added to ID cache. Affected files
4570 silcd/packet_receive.c and silcd/server.c.
4572 * When client's sock->user_data is freed, NULL also the
4573 client->router and client->connection pointers. Added check
4574 for these pointers being NULL to various places around the
4575 code. Affected file silcd/server.c.
4577 * Added client->data.registered == TRUE checks to various
4578 places around the code to assure that unregistered client's
4579 are not handled when it is not allowed. Affected file
4582 * Added `bool registered' fields to all
4583 silc_idlist_[server|client]_get_* routines to indicate whether
4584 the fetched client needs to be registered or not. Affected
4585 file silcd/idlist.[ch].
4587 * Add your own entry as registered to the ID cache in the
4588 server. Affected file server.c.
4590 * Fixed a bug in silc_server_new_server. The SilcServer was
4591 set as the new server's context instead of SilcServerEntry.
4592 This naturally caused some weird bugs.
4594 * Added "updated" field the SilcChannelEntry which indicates
4595 the time since the channel entry was last accessed. This
4596 can be used to determine whether it is necessary to
4597 announce the channel after backup resuming protocol.
4598 Affected files silcd/idlist.[ch].
4600 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4602 * Do not delete the channel rekey task when adding it
4603 for in silc_server_create_channel_key.
4605 * Changed the silc_server_create_channel_key to return
4606 TRUE or FALSE to indicate the success of the channel key
4609 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4611 * Fixed MSVC++ project files and added missing files to
4612 Makefiles under win32/.
4614 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4616 * Do not add TCP_NODELAY flag if the operating system
4617 does not have it defined. Affected files are
4618 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4620 * Fixed buffer overflow from Irssi SILC Client. Affected
4621 file irssi/src/fe-common/core/themes.c.
4623 * Fixed double free in client library in the file
4624 lib/silcclient/client.c when disconnecting from server.
4626 * Applied double free patch from cras to Irssi SILC client.
4627 Affected files irssi/src/core/[modules/expandos].c
4629 * Fixed the disconnection handling to Irssi SILC Client.
4630 The application must call silc_client_close_connection
4631 in ops->connect client operation in case of failure of
4632 the connection. Affected file is
4633 irssi/src/silc/core/client_ops.c.
4635 * Do not set sock->protocol to NULL in the function
4636 silc_client_close_connection after executing the protocol's
4637 final callback since the sock might not be valid anymore.
4638 Affected file lib/silcclient/client.c.
4640 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4642 * Do not enable SILC_THREADS if the linking with libpthread
4643 did not happen. Affected file configure.in.pre.
4645 * Added notion to protocol specification that server must
4646 verify the sent authentication payload with CMODE when
4647 setting the channel founder key. Implemented it to the
4648 server. Affected file silcd/command.c.
4650 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4652 * Added _EXTRA_DIST SILC distribution variable to the
4653 distributions file. It is used to conditionally add extra
4654 files or directories to the specific distribution. Affected
4655 files ./prepare, Makefile.am.pre and distributions.
4657 Removed the `_' from the start of the distribution names.
4660 * Added README.WIN32 for instructions to compile the Toolkit
4663 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4665 * Fixed a double free in disconnection in the server. Affected
4666 file is silcd/server.c.
4668 * Fixed the lib/silcske/groups.c to work now also with GMP
4669 MP library. The string conversion did not work when using
4670 specific base and the base is indicated in the string as well.
4672 * Created win32/ directory which now includes MSVC++ specific
4673 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4674 It will appear only in the toolkit distribution
4676 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4678 * Changed the key material distribution function in case when
4679 the hash output is too short. The data is now concatenated
4680 a bit differently than it used to. Made the change to the
4681 SKE protocol specification.
4683 * Added better GMP detection to configure.in.pre. A patch
4686 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4688 * Fixed a minor bug in SKE that might cause some problem on
4689 some platforms. Affected file lib/silcske/silcske.c.
4691 * Added the cookie checking for initiator in the SKE. It checks
4692 that the responder returns the sent cookie unmodified. The
4693 affected file is lib/silcske/silcske.c. Added new SKE
4694 error type INVALID_COOKIE that can be sent during the
4695 negotiation. Fixed some memory leaks as well.
4697 * Added the "invalid cookie" error message to Irssi SILC client's
4700 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4702 * Added `task_max' field to the SilcClientParams to indicate
4703 the maximum tasks the scheduler can handle. If set to zero,
4704 default values are used. Affected file lib/silcclient/silcapi.h.
4706 * Fixed memory leaks in silc_client_close_connection. Affected
4707 file lib/silcclient/client.c.
4709 * Added silc_client_del_client_entry to client library to free
4710 all memory of given client entry. Affected file is
4711 lib/silcclient/idlist.[ch].
4713 * Added new functions silc_client_del_channel and
4714 silc_client_del_server to delete channel and server entries.
4715 Affected file lib/silcclient/[silcapi.h/idlist.c].
4717 * Removed silc_client_del_client_by_id from silcapi.h.
4719 * Fixed the INFO command to return the server's own info
4720 correctly when querying by Server ID. Affected file is
4723 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4725 * Removed the non-blocking settings in WIN32 code in the
4726 silc_sock_[read/write] and added SleepEx instead. Affected
4727 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4728 of input data is now checked with FIONREAD and ioctlsocket.
4730 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4732 * Call silc_schedule_task_del_by_context in the
4733 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4734 Affected file lib/silccore/silcprotocol.c.
4736 * Call silc_protocol_cancel for active protocols in the
4737 silc_server_close_connection if the funtion
4738 silc_server_free_sock_user_data has not been called.
4739 Affected file silcd/server.c.
4741 * Generic tasks cannot be deleted using the del_by_fd
4742 task deleting function since generic tasks does not match
4743 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4745 * Added a notion to SILCOPER help file that the SILCOPER works
4746 only on router server, not on normal server.
4748 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4750 * Added for WIN32 support for the new scheduler as well.
4751 Affected file lib/silcutil/win32/silcwin32schedule.c.
4753 * Fixed the SHA1 implementation to work on various platforms.
4755 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4757 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4758 API. It is part of the scheduler now. Everything else is
4759 as previously but some functions has changed their names.
4760 Checkout the lib/silcutil/silcschedule.h for the interface.
4761 Updated all applications to use the new interface. Affected
4762 files are lib/silcutil/silcschedule.[ch].
4764 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4766 * Found a bug in the SKE implementation. The HASH value,
4767 specified by the protocol, was not computed correctly. The
4768 public key of the responder was not added to the computation
4769 even though it is mandatory. Affected file lib/silcske/silcske.c.
4770 This unfortunately causes incompatibilities with older
4771 clients and servers.
4773 * Added WIN32 specific network init and uninit functions:
4774 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4775 the Winsock2. Affected file lib/silcutil/silcnet.h and
4776 lib/silcutil/win32/silcwin32net.c.
4778 * Set the socket always to nonblocking mode on WIN32 after
4779 reading data or writing data. Affected file is
4780 lib/silcutil/win32/silcwin32sockconn.c.
4782 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4784 * Fixed various compilation problems under WIN32. Affected
4785 files lib/silcutil/win32/silcwin32thread.c and
4786 lib/silcutil/win32/silcwin32schedule.c.
4788 * Removed all _internal.h #includes from public header
4789 files. Internal headers must never be included from
4792 Removed also the lib/silcske/payload_internal.h file.
4794 * All include files that may be needed (public and some others
4795 included by the public headers) by application developers are
4796 now copied to the ./includes directory. It does not copy any
4797 internal headers. Affected file Makefile.defines.pre and all
4798 Makefile.am's under lib/ and subdirs.
4800 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4802 * Do not change the ~/.silc directory's permissions automatically.
4803 Affected file irssi/src/silc/core/clientutil.c.
4805 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4807 * Do not cancel the protocol in silc_server_close_connection
4808 it might cause recursion. Now cancelled in the function
4809 silc_server_free_sock_user_data. Affected file silcd/server.c.
4811 * Fixed the silc_server_remove_clients_by_server to regenerate
4812 the channel keys correctly finally. Added also new function
4813 silc_server_remove_clients_channels to actually do it.
4814 Affected file silcd/server.c.
4816 * Fixed the silc_server_new_channel to not crash by giving
4817 wrong router to the new channel. Affected file is
4818 silcd/packet_receive.c.
4820 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4822 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4823 which is given as argument to the silc_client_alloc now.
4824 It can be used to configure the client and set various parameters
4825 that affect the function of the client.
4827 * The USERS command in server did not check whether the channel
4828 is private or secret. Affected file silcd/command.c.
4830 * Added new argument to the USERS command in protocol specification.
4831 The USERS command now can take the channel name as argument
4832 as well. Added support for this in client and server and
4833 updated the protocol specs.
4835 * Completed the GETKEY command in client. It can be now used
4836 to fetch also servers public key not only some clients.
4837 Affected files lib/silcclient/command[_reply].c.
4839 * Added silc_client_get_server to return server entry by the
4840 server name. Affected files lib/silcclient/silcapi.h and
4843 * Redefined the IDENTIFY command in protocol specification to be
4844 more generic. It now can be used to query information about
4845 any entity in the SILC Network, including clients, servers and
4846 channels. The query may be based either the entity's name
4847 or the ID. Added support for this in both client and server.
4849 Affected files silcd/command.c and lib/silcclient/command.c
4850 and command_reply.c.
4852 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4853 the _from_client and _from_server functions. Affected file
4856 * Added silc_client_get_channel_by_id_resolve to the file
4857 lib/silcclient/silcapi.h to resolve channel information by
4858 its ID. Added also silc_client_get_channel_by_id that
4859 does not resolve it from the server.
4861 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4863 * Added SilcServerEntry context into the client library
4864 to represent one server. The INFO command now allocates
4865 these to save the resolved server info. For now on the
4866 client library will also keep information about servers,
4867 connected and resolved with INFO.
4869 The INFO command now allocates the SilcServerEntry context
4870 and saves the server info there. The COMMAND_REPLY in
4871 the INFO now returns the parameters to application in
4872 same order as defined in the protocol specification.
4874 The entries are cached in the client->server_cache.
4876 * The INFO command is now issued after received the Client ID
4877 from the server. Affected file lib/silcclient/client.c.
4879 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4880 to the application as the mode changer might be server.
4881 It is guaranteed that NULL is not returned anymore to the
4882 application. Affected file lib/silcclient/client_notify.c.
4884 The ID Type is now also passed to the application so that
4885 it can check whether the returned entry is SilcClientEntry
4888 Added new function silc_client_get_server_by_id to return
4889 the server entry by ID. Affected files are the
4890 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4892 * Do not create the channel in the Irssi SILC Client when issuing
4893 the JOIN command but when received the sucessful JOIN command
4894 reply. Otherwise the channel might get created even though we
4895 could not join it. The Affected file is
4896 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4898 * Fixed a channel joining bug in router. The router must also
4899 check the channel modes, invite and ban lists etc. when serving
4900 the JOIN command sent by normal server. Affected file is
4901 silcd/command.c. The router now resolves the client's
4902 information from the server who sent the JOIN command if it
4903 does not know it, and processes the JOIN command only after
4906 * Changed the SilcCommandCb to take new argument; void *context2.
4907 Affected file lib/silccore/silccommand.h
4909 The second argument in the command callbacks in the server now
4910 includes the SilcServerCommandReplyContext if the command was
4911 called as pending command callback from the command reply.
4912 Otherwise it is NULL. When called as pending the status of the
4913 command reply will be checked and if it was erronous the
4914 error will be sent to the original sender of the command.
4915 This way the client always receives the error messages even
4916 though the server was actually the one who received the error
4917 when it resent the command to router, for example. Affected
4918 files silcd/command[_reply].[ch].
4920 * Fixed sending WHOWAS command's error message to client if
4921 the requested client could not be found. It was missing.
4924 * Changed the CMODE and CUMODE commands reply arguments in the
4925 protocol specification. The Channel ID is now sent in both
4926 of the commands to identify the channel. Implemented this
4927 new feature to the client and server. Affected files
4928 lib/silcclient/command_reply.c and silcd/command.c.
4930 * Made better checks for invite and ban lists in the JOIN
4931 command in server. Affected file silcd/command.c.
4933 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4935 * The server now performs the incoming host IP/DNS lookup
4936 using the silc_socket_host_lookup and thus does not block
4937 the server anymore. Affected file silcd/server.c.
4939 * Completed the multi-thread support for SILC Scheduler in
4940 the lib/silcutil/silcschedule.c.
4942 * Fixed the configure.in.pre to detect the pthread correctly
4945 * Fixed a deadlock in silc_task_queue_wakeup in the file
4946 lib/silcutil/silctask.c.
4948 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4950 * Added new function silc_schedule_wakeup that is used in
4951 multi-threaded environment to wakeup the main thread's
4952 schduler. It needs to be used when a thread adds a new task
4953 or removes a task from task queues. After waking up, the
4954 scheduler will detect the task queue changes. If threads
4955 support is not compiled in this function has no effect.
4956 Implemented the wakeup mechanism to both Unix and WIN32
4957 systems. Affected files are lib/silcutil/silcschedule.[ch],
4958 lib/silcutil/unix/silcunixschedule.c and the
4959 lib/silcutil/win32/silcwin32schedule.c.
4961 * Added new function silc_task_queue_wakeup to wakeup the
4962 scheduler by the specified task queue. Affected file
4963 lib/silcutil/silctask.[ch].
4965 * The silc_socket_host_lookup_start now wakes up the scheduler
4966 after adding the timeout task. Affected file is
4967 lib/silcutil/silcsockconn.c.
4969 * The silc_socket_host_lookup is synchronous now if the threads
4970 support is not compiled in. However, the callback is still
4971 called asyncronously through the scheduler, anyway. Affected
4972 file lib/silcutil/silcsockconn.c.
4974 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4976 * Added new function silc_socket_host_lookup to perform
4977 asynchronous IP and FQDN lookups for the socket connection.
4978 Affected files lib/silcutil/silcsockconn.[ch].
4980 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4982 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4983 that may or may not compile the mutex support in.
4985 Changed the silc_mutex_alloc interface. It allocates the
4986 mutex now to the sent pointer and returns TRUE or FALSE.
4988 Affected file lib/silcutil/silcmutex.h.
4990 * Wrote the SILC Task Queue interface to support multi-threads.
4991 Affected file lib/silcutil/silctask.[ch].
4993 * Wrote the SILC Scheduler to support multi-threads. Affected
4994 file lib/silcutil/silcschedule.c.
4996 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4998 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4999 in lib/silcutil/win32/.
5001 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5003 * Defined SILC Mutex API and SILC Thread API and implemented
5004 them for Unix. Affected files are
5005 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
5006 lib/silcutil/unix/silcunixmutex.c and
5007 lib/silcutil/unix/silcunixthread.c.
5009 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5011 * Fixed the silc_server_remove_clients_by_server's channel
5012 key re-generation. The hash table handling was incorrect
5013 and would not work with many channels. Affected file is
5016 * Fixed some memory leaks around the server code.
5018 * Rewrote the silc_server_get_users_on_channel to support IPv6
5019 based Client ID's. Affected file silcd/server.c.
5021 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
5022 specification. However, a separate document must be written
5023 to define the detailed signing procedure and the payload
5024 associated with the flag. Defined the flag to the
5025 lib/silccore/silcchannel.h as well.
5027 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5029 * Changed the dynamic tables to static size tables in the
5030 lib/silccrypt/silchmac.c.
5032 * Removed GCC dependencies from the code. A patch by cras.
5034 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5036 * Do not show the error "Error receiving packet bla bla"
5037 in server if it really was not an error (-2 means that reading
5038 is pending). Affected file silcd/server.c.
5040 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5042 * Fixed a possible crash in silc_server_remove_clients_by_server
5043 in silcd/server.c. Fixed there also some memory leaks.
5045 * Fixed the silc_idlist_replace_client_id. It could replace
5046 wrong key in the hash table. Affected file silcd/idlist.c.
5048 * Do not check whether there are global users on the channel
5049 if the channel->global_users is FALSE. Affected functions
5050 silc_server_remove_from_one_channel and
5051 silc_server_remove_from_channels in silcd/server.c. Also,
5052 do not check if the removed client is local as we can be
5053 sure that global client was not removed from the channel
5054 and checking for global users is not needed.
5056 * The silc_server_remove_clients_by_server now re-generates
5057 the channel keys correctly for those channels that had
5058 clients removed from them. Affected file silcd/server.c.
5060 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5062 * Found the reason of random crashes in the server. We weren't
5063 ignoring the SIGPIPE signal (which can be sent in write())
5064 and it crashed the server. Affected file silcd/silcd.c.
5066 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5068 * Assure that sock->user_data is not NULL in the function
5069 silc_server_packet_send in silcd/packet_send.c.
5071 * Disconnect the remote connection if it could not be added
5072 to any ID lists in the server. The affected file is
5075 * Check in silc_server_packet_send[_real/dest] that the
5076 socket is not disconnecting and ignore the data if it is.
5077 Affected file silcd/packet_send.c.
5079 * Define inline to __inline on native WIN32 compilation.
5080 Affected file includes/silcwin32.h.
5082 * Added some explicit type casts for inline code since MSVC
5083 require them. Affected files lib/silcutil/silcbuffer.h,
5084 lib/trq/silcdlist.h and lib/trq/silclist.h.
5086 * Print warning in log files from now on if the packet
5087 decryption fails. Affected file silcd/server.c.
5089 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5091 * Changed the `say' client operation's interface to accept
5092 new `type' argument to indicate the type of the message sent
5093 by the library. The application may filter the library's
5094 messages according the type. The affected file is the
5095 lib/silcclient/silcapi.h.
5097 * Added two new functions to lib/silcclient/silcapi.h:
5098 silc_client_del_client and silc_client_del_client_by_id.
5099 Affected file lib/silcclient/idlist.c.
5101 * Moved the clientincludes.h from includes/ to silc/ and
5102 serverincludes.h from includes/ to silcd/.
5104 * The modes for the CMODE and CUMODE are now passed as
5105 uint32 for application with COMMAND_REPLY. The affected
5106 file is lib/silcclient/command_reply.c.
5108 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5110 * /WHOIS without arguments shows client's own information.
5111 Affected file lib/silcclient/command.c.
5113 * Changed PING to not accept any arguments. The specs
5114 says that client can ping only the connected server so
5115 requiring an argument is not needed. Affected file is
5116 lib/silcclient/command.c.
5118 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5120 * Fixed a fatal bug in private message sending and reception
5121 encryption and decryption when using private message keys.
5122 The implementation was incorrect and did not follow the
5123 specification. It causd that some of the message were
5124 lost since it did not use the sending and receiving keys
5125 as the protocol suggests. This has been fixed and will cause
5126 incompatibilities with older clients when sending private
5127 message encrypted with private message keys. Affected files
5128 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
5129 and various other in Irssi SILC Client.
5131 Added `responder' boolean argument to the functions
5132 silc_client_add_private_message_key[_ske] to indicate when
5133 the key is added as responder or initiator of the key
5136 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5138 * Removed the silc_ske_check_version function and created
5139 a SilcSKECheckVersion callback. Added also a function
5140 silc_ske_set_callbacks that is now used to set all SKE
5141 callbacks. The callback functions are not given to
5142 the SKE functions anymore, but this function is used to
5145 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
5147 * Added `silc_version' argument to the silc_client_alloc
5148 to define the version of the application for the library.
5149 The library will use the version string to compare it
5150 against the remote host's (usually a server) version
5151 string. Affected file lib/silcclient/silcapi.h
5153 * Added the KE protocol context to Key Agreement context
5154 in client library so that we can abort the SKE if it
5155 is in process when we get timeout. Affected file is
5156 lib/silcclient/client_keyagr.c.
5158 * Do not resolve the client ID forever if it returns in the
5159 first time that such client does not exist. This was done
5160 for example with private message. Affected file is
5161 lib/silcclient/client_prvmsg.c.
5163 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5165 * Do not add regex.h for WIN32. The affected file
5166 includes/silcincludes.h.
5168 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
5169 not work yet 100%. It generates the DLL's automatically
5170 when compiling with --with-win32 under cygwin.
5172 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5174 * lib/contrib/regex.c is not compiled on WIN32.
5176 * Added silc_net_get_socket_opt function to the
5177 lib/silcutil/silcnet.h.
5179 * Added includes/silcwin32.h for WIN32 specific includes
5182 * Do not use ptime structure or any of the posix process
5183 functions on WIN32 in lib/silccrypt/silrng.c.
5185 * Added silc_gettimeofday to provide generic function
5186 for struct timeval on all platforms. Added the function
5187 to lib/silcutil/silcutil.h.
5189 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5191 * Moved the lib/silccore/silcsockconn.[ch] to the utility
5192 library as they clearly belong there. As a plus side we
5193 can make the actual socket connection routines platform
5196 Added also new generic function silc_socket_read and
5197 silc_socket_write (that used to be silc_packet_[read/write].
5198 The implementation of these are platform specific.
5200 * Added WIN32 specific routines of silc_socket_[read/write]
5201 to lib/silcutil/win32/silcwin32sockconn.c.
5203 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5205 * Added preliminary support for native WIN32 compilation under
5206 cygwin (using the -mno-cygwin option for GCC) to the
5207 ./configure.in.pre. The --with-win32 now prepares the
5208 compilation for native WIN32.
5210 * Rewrote the SILC Scheduler interface in the file
5211 lib/silcutil/silcschedule.h. The scheduler is now context
5212 based and does not have anymore any global static scheduler.
5213 Moved the Unix scheduler to the lib/silcutil/unix/ directory
5214 and created lib/silcutil/win32 directory for WIN32 based
5217 * Added Unix specific network routines to the
5218 lib/silcutil/unix/silcunixnet.c and the old
5219 lib/silcutil/silcnet.c includes now only generic routines.
5221 Added WIN32 specific network routines to the
5222 lib/silcutil/win32/silcwin32net.c.
5224 * Added Unix specific utility functions from the
5225 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
5227 * Added WIN32 SILC Scheduler to the file
5228 lib/silcutil/win32/silcwin32schedule.c. The code is of course
5231 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5233 * Do not handle JOIN notify in the server if the target client
5234 is not registered (idata->registered == FALSE). The affected
5235 file is silcd/packet_receive.c.
5237 * Update the nickrec->founder in event_cumode in the Irssi SILC
5238 client. Affected file irssi/src/silc/core/silc-channels.c.
5240 * Fixed the CUMODE_CHANGE notify handling in the server when
5241 server and router are announcing their clients on channels.
5242 Now the mode changes are saved and notified correctly. The
5243 affected file is /silcd/packet_receive.c.
5245 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
5246 They really did not replace the cache entry in the ID Cache.
5247 Now they do that. Affected file silcd/idlist.c.
5249 * Fixed the KICK notify handling in the Irssi SILC client to
5250 update the channel records so that the kicked client does not
5251 appear to be on the channel. The affected file is
5252 irssi/src/silc/core/silc-channels.c.
5254 * Always update the conn->current_channel when executing command
5255 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
5257 * Fixed the KILL notify handling in Irssi SILC client to remove
5258 the killed client on all channels.
5260 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5262 * Fixed the silc_parse_command_line to remove extra spaces
5263 from the start and end of the arguments. Affected file is
5264 lib/silcutil/silcutil.c.
5266 * Cancel and free any active protocol in the function
5267 silc_server_close_connection. Affected file silcd/server.c.
5269 * Cancel and free any active protocol in the function
5270 silc_client_close_connction. Affected file is
5271 lib/silcclient/client.c.
5273 * Do not execute the KILL command for clients that are in
5274 history (ie. they are not in the network). Affected file is
5277 * Fixed KILL notify handling, client does not crash anymore.
5278 Affected file irssi/src/silc/core/silc-channels.c.
5280 * Reduced the default packet buffer size from 2048 to 1024 in
5281 lib/silccore/silcpacket.c.
5283 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5284 counter to the SKE context that is incresed when the SKE library
5285 performs async operation outside the library. If the outside
5286 process frees the SKE context and FREED status will be set
5287 and the library will detect after the sync operation that the
5288 libary is freed. The affected files are
5289 lib/silcske/silcske[_status].[ch].
5291 * Resolve the client entry information in the function
5292 silc_client_channel_message to assure that NULL pointer is not
5293 passed as client entry to the application. */
5295 * Fixed the task timeout calculation to assure that there is
5296 never negative timeouts. The affected file is
5297 lib/silcutil/silcschedule.c.
5299 * Fixed the channel user mode notification sending in server.
5300 It was sent point-to-point to the router (or to server by router)
5301 but it needs to be destined to a channel. The routines now
5302 supports sending the channel user mode notifys to the channels
5303 when announcing clients and channels. Affected files are
5304 silcd/server.c and silcd/packet_receive.c.
5306 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5307 It did not actually replace the old channel entry in the cache.
5308 Affected file lib/silcclient/client_notify.c.
5310 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5312 * Fixed a possible crash in silc_packet_send_prepare. It now
5313 assures always that there is enough space in the buffer and
5314 at the tail area of the buffer (for MAC).
5316 Fixed the inbound buffer reallocation in silc_packet_read.
5317 It was old code and did not handle the reallocation correctly.
5320 The affected file is lib/silccore/silcpacket.c.
5322 * Fixed buffer overflow in silc_parse_nickname in the file
5323 lib/silcutil/silcutil.c.
5325 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5327 * make install generates new server keys only if there is not
5330 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5332 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5333 Added check that if the NOREPLY is set then we will not send
5334 the away message. This avoids infinite loop of away messages
5335 if both clients are away. The affected file is
5336 lib/silcclient/client_prvmsg.c.
5338 * Fixed client crash if /NICK was given without arguments.
5339 Affected file lib/silcclient/command.c.
5341 * Server does not send the invite list in INVITE command back
5342 to the client if the list was not altered. Added this notion
5343 to the protocol spec as well. Affected file silcd/command.c.
5345 Fixed possible crash in INVITE command by checking the
5346 value of silc_server_get_client_route command.
5348 * Fixed the INVITE notify type handling. The arguments are now
5349 taken in correct order and client does not crash. The affected
5350 file is irssi/src/silc/core/silc-channels.c.
5352 Removed the "Inviting xxx to channel" message from the
5353 client library away and let the application handle it.
5354 Affected file lib/silcclient/command.c. Added that message
5355 to Irssi SILC client's message formats.
5357 * Fixed CMODE command crash in client. It now checks the
5358 amount of arguments correctly and does not crash. The affected
5359 file is lib/silcclient/command.c.
5361 * Do not create new channel automatically in silc_channels_join
5362 but check whether the channel by that name already exists.
5363 Affected file irssi/silc/core/silc-channels.c.
5365 * Do not send the SERVER_SIGNOFF to router if the disconnected
5366 entity was the router. Affected file silcd/server.c.
5368 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5369 SILC client as it was missing from there.
5371 Added the handling of the KICK notify to the Irssi SILC client
5372 as it was missing. Added "you have been kicked" message to
5373 Irssi SILC client's message modules formats.
5375 Added the handing of the KILL notify to the Irssi SILC client
5376 as it was missing. Added the kill message module formats
5379 The affected file is irssi/src/silc/core/silc-channels.c.
5381 * The router did not save the channel mode the server announced.
5382 Affected file silcd/packet_receive.c.
5384 * Fixed a possible crash in INFO command in server. If the
5385 server did not provide the server info it crashed. Affected
5386 file silcd/command.c.
5388 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5390 * Fixed the GETKEY command in the server to check also the
5391 global list. Otherwise the GETKEY would not work correctly
5392 in normal SILC server. Affected file silcd/command.c.
5394 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * Fixed GETKEY crash, it crashed if the command did not succseed.
5398 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5400 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5401 is now real and not just an macro interface to GMP.
5403 Removed the entire GMP from the source tree and imported new
5404 NSS MPI library instead. Reason for removing GMP is that it is
5405 extremely large and compiles extremely slow. The NSS MPI
5406 is only a few files and compiles in less than 10 seconds.
5407 The speed is also about the same as GMP. The MPI is imported
5408 to lib/silcmath/mpi.
5410 If the system has GMP installed we will still use the GMP.
5411 If it is not then the NSS MPI will be compiled.
5413 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5415 * Merged a long nickname (127 characters long) crash bugfix from
5416 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5418 * Merged a freed memory reference bugfix from Irssi CVS tree.
5419 Affected file irssi/src/core/commands.c.
5421 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5423 * Added the server's public key sving and verification to the
5424 server when performing the SKE. This was missing and the
5425 remote server's (or router's) public key was accepted without
5426 checking whether we have it previously or trust it at all.
5427 Affected file silcd/protocol.c.
5429 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5431 * Check in the silc_server_timeout_remote if protocol is active
5432 and make sure that the protocol's final callback is called so
5433 that all memory if freed. Affected file silcd/server.c.
5435 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5437 * silc_server_whois_send_reply crashed the server if the nickname
5438 was 127 characters long. Affected file silcd/command.c.
5440 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5442 * Added sanity check to the silc_server_new_client. If the hostname
5443 is provided inside username then check that the provided hostname
5444 really is the same as the resolved one. If the hostname was not
5445 resolved then check it from the public key. Affected file is
5446 silcd/packet_receive.c.
5448 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5449 if the server disconnected us and the connection is not valid
5450 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5452 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5453 the library to the lib/silcutil/silcutil.[ch].
5455 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5457 * Close log file after open. Affected file
5458 lib/silcutil/silclog.c.
5460 * Check whether sock == NULL in silc_client_send_packet and return
5461 if it is. Affected file lib/silcclient/silcclient.c.
5463 * Check rec->entry == NULL in the Irssi SILC Client before
5464 sending the channel message. Affecte file is
5465 irssi/src/silc/core/silc-servers.c.
5467 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5469 * Merged a splitted window bugfix from Irssi CVS tree. The
5470 affected file is irssi/src/fe-text/textbuffer-view.c.
5472 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5473 It did not print nickname.
5475 * Improved the distributions system a bit.
5477 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5479 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5480 irssi/src/fe-text/gui-window.c.
5482 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5483 to in-active server. The affected file is
5484 irssi/src/silc/core/client_ops.c.
5486 * Resolve the client in USERS command reply if the entry does
5487 not have username resolved. The affected file is
5488 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5489 command to WHOIS command to really resolve stuff. The USERS
5490 is not used any more in any critical section so WHOIS can
5491 be used even though it might be slower than IDENTIFY.
5493 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5496 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5498 * Changed the protocol API a bit more consistent in the
5499 lib/silccore/silcprotocol.[ch].
5501 * Changed the following headers to ROBODoc format:
5503 lib/silccore/silcpayload.h
5504 lib/silccore/silcprotocol.h
5505 lib/silccore/silcsockconn.h
5507 All core library headers are now formatted.
5509 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5511 * Fixed a bug in Irssi SILC client; do not show that you are
5512 server/router operator if you really are not. Affected file is
5513 irssi/src/silc/core/client_ops.c.
5515 * Renamed silc_command_free_payload to silc_command_payload_free.
5516 Affected file lib/silccore/silccommand.h
5518 * Added silcmath.h to include the prototoypes of various routines
5519 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5522 * Changed the following headers to ROBODoc format:
5524 lib/silccore/silcchannel.h
5525 lib/silccore/silccommand.h
5526 lib/silccore/silcid.h
5527 lib/silccore/silcidcache.h
5528 lib/silccore/silcmode.h
5529 lib/silccore/silcnotify.h
5530 lib/silccore/silcpacket.h
5531 lib/silcmath/silcmath.h
5533 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * Added checking to the server code not to start the server if
5536 ciphers and stuff are not configured properly. Affected files
5537 silcd/serverconfig.[h] and silcd/server.c.
5539 * Changed the layout of the header files of the public interfaces
5540 in the SILC libraries. The new layout supports ROBODoc
5541 documentation tool (and some others) so that it is easy to create
5542 a library reference manual. All the other headers and source
5543 code must still follow the CodingStyle document. Also source
5544 code must not include these ROBODoc stuffs, only the headers.
5545 Furthermore, all public interface headers must now be named
5546 by using `silc' prefix, example: silcapi.h, silccipher.h.
5547 Some files were renamed due to this. All the other headers
5548 must not be used as public interfaces. I will update the
5549 CodingStyle document later. Changed following headers, so far:
5551 lib/silcclient/silcapi.h
5552 lib/silccore/silcauth.h
5553 lib/silccore/silcprivate.h
5554 lib/silccrypt/silcdh.h
5556 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5560 * Removed silc_client_packet_send_flush from the client library
5561 as it is not needed. Affected file lib/silcclient/client.[ch].
5563 * Added printing of message of unresolved authentication method
5564 to the Irssi SILC client. Added it to the module formats.
5565 Removed the same message from the client library.
5567 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5569 * Added new distribution feature, DISTLABEL. Every distribution
5570 can define own preprocessor label that can be used in the
5571 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5572 file distributions, acconfig.h.pre and prepare.
5574 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5576 * Added Makefile.defines_int to include the actual definitions
5577 for Makefile.defines.in. Tested the new distribution system,
5578 created distributions and tested installation.
5580 * Added AWAY message printing to the Irssi SILC client. Added
5581 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5583 * Added SCONNECT command to call the SILC's CONNECT command.
5584 Cannot use CONNECT directly since Irssi uses that internally.
5585 Affected file irssi/src/silc/core/silc-servers.c.
5587 Added ACTION local command. It is same as ME command but takes
5588 the channel as mandatory argument.
5590 Rewrote some of the Irssi's help files to suite for SILC
5593 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5595 * Added Makefile.defines[.in] that should for now on be included
5596 in all Makefile.am file in the source tree. That file includes
5597 all common compilation definitions for SILC source tree.
5599 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5601 * Minor changes to the ./prepare script to change the package
5602 name according the distribution name to the configure.in.
5604 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5606 * Created new distribution system. Added file `distributions'
5607 that defines all the distributions that can be created out of
5608 the SILC source tree. The ./prepare script now reads that
5609 file to determine how to prepare the distributions. The
5610 first argument to the ./prepare is the name of the distribution
5611 and second is the version of the distribution. If given
5612 without arguments it creates the default (toolkit) distribution
5613 with the default version (defined in ./prepare).
5615 All Makefile.am files that are subject to the distributions
5616 are now named as Makefile.am.pre. These are ./Makefile.am
5617 and lib/Makefile.am. Others may be changed later.
5619 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5621 * Added invite list, ban list, some key management and connection
5622 error message printing to module formats in the Irssi SILC client.
5624 * Added new silc_client_set_away_message to set the away message
5625 that is back to the person who sent private message. The
5626 affected file lib/silcclient/silcapi.h and the
5627 lib/silcclient/client_prvmsg.c.
5629 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5631 * Fixed the private message sending in the Irssi SILC client,
5632 added local command KEY to the Irssi SILC client.
5634 Added key management and key agreement message formats to the
5635 irssi/src/fe-common/silc/module-formats.[ch].
5637 Added USERS (alias WHO) printing, server/router operator
5638 indication and LIST command printing to the module formats.
5640 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5642 * Fixed channel joining notify handling, cumode notify handling
5643 from Irssi SILC client.
5645 * Added SILC specific module-formats to the Irssi SILC client so
5646 that SILC specific message hilighting, colors etc is possible.
5647 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5649 Added channel mode, channel user mode, actions, notices,
5650 whois and whowas printing to the the module-formats.c.
5652 * Fixed a bug in channel deletion in the server. The channel
5653 is not left to the cache even if the channel founder auth mode
5654 is set when there are no users anymore on the channel. Affected
5655 file silcd/server.c.
5657 * The silc_net_localhost now resolves the entire hostname including
5658 the domain name. Affected file lib/silcutil/silcnet.c.
5660 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5662 * Changed the ask_passphrase client operation to be ascynchronous.
5663 It has now a completion callback and a context that the
5664 application must call after it has got the passphrase from
5665 the user. Affected files lib/silcclient/silcapi.h,
5666 lib/silcclient/protocol.c, lib/silcclient/command.c and
5669 Added SilcAskPassphrase callback that the application calls
5670 to deliver the passphrase to the library.
5672 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5673 The public key verification and especially a certificate
5674 verification is asynchronous procedure.
5676 Added new SILC_SKE_STATUS_PENDING status to indicate the
5677 request is pending and a callback will be called to finalize
5680 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5681 indicate that remote end did not send its public key (or
5682 certificate), even though we require it. Added check for this
5683 condition in the SKE. This was a security bug, now fixed.
5685 Defined new SilcSKEVerifyCbCompletion callback that is called
5686 when the verification process is completed.
5688 The affected files lib/silcske/silcske_status.h and
5689 lib/silcske/silcske.[ch].
5691 * Changed the verify_public_key client operation to be async
5692 as well. Defined SilcVerifyPublicKey callback that is used to
5693 indicate the success of the public key verification process.
5695 Changed the server and client to use the new async client
5698 * Changed the Irssi SILC client's internal scheduler to be called
5699 twice as many times as it used to be. As a result the client
5700 should be a bit faster now. Affected file is
5701 irssi/src/silc/core/silc-core.c.
5703 * Added support to Irssi SILC client of asynchronous public key
5704 verification and passphrase inquiry. Affected file is
5705 irssi/src/silc/core/silc-core.c.
5707 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5709 * Do not say "You have left channel %s" in client library.
5710 Moved it to the application. Affected files are
5711 lib/silcclient/command.c and silc/client_ops.c.
5713 * Fixed silc_client_get_clients. Command context was not
5714 duplicated and was freed memory in the callback. Affected
5715 file lib/silcclient/idlist.c.
5717 * Do not say "you are now talking..." on JOIN command in the
5718 client library. The appliation must handle it.
5720 * Do not say ".. changed topic to" in command reply in the
5721 client libary. The application must handle it.
5723 * Fixed TOPIC command sending in the client library.
5725 * Fixed a memory leak in silc_client_command_free in the file
5726 lib/silcclient/command.c.
5728 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5730 * Imported a modified version of Irssi client to the source tree.
5731 The Irssi will be used to create a new client called
5732 Irssi SILC. Imported to irssi/.
5734 Added silc_core_init_finish function to the Irssi. Affected
5735 file irssi/configure.in.
5737 A lot changes in the Makefile.ams around the irssi tree.
5739 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5741 * Do not rehash if the new size is same as the old size of the
5742 hash table, in the silc_hash_table_rehash*. The affected file
5743 lib/silcutil/silchashtable.c.
5745 * Replaced hash_table_del_by_context calls from the server
5746 (when channel->user_list and client->channels) to the
5747 hash_table_del as it is sufficient and faster.
5749 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5751 * Added silc_hash_table_list, silc_hash_table_get and the
5752 SilcHashTableList structure to provide an alternative way to
5753 traverse the hash table. The affected files are
5754 lib/silcutil/silchashtable.[ch].
5756 * Changed the server's idlist routines to use the hash table
5757 routines to optimize the code.
5759 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * Replaced the client entry's `channel' list and channel entry's
5762 `user_list' list to hash tables for optimized lookup. Changed
5763 the code to use the hash table interface around the code.
5764 Affected file lib/silcd/idlist.[ch].
5766 * Added `auto_rehash' boolean argument to the function
5767 silc_hash_table_alloc to indicate whether the hash table should
5768 auto-rehash when it thinks is appropriate time. It will
5769 increase the hash table size if the there is twice as much
5770 entries in the table than the size of the table, and will
5771 decrease the size if there are twice as less entries than
5772 the size of the table.
5774 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5776 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5778 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5780 * silc_idcache_purge_by_context deletes the entry now by context
5781 as it is supposed to do. Affected file lib/silccore/idcache.c.
5783 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5784 client is not anymore valid (WHOWAS givens the info) and not
5785 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5787 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5789 * Removed the `data' and `data_len' arguments from the ID Cache
5790 interfaces and added `name' argument. ID Cache does not handle
5791 anymore the binary data only a names associated with given ID.
5793 * When hashing a Client ID with silc_hash_id the entire ID is
5794 not hashed anymore, instead only the hash of the Client ID is
5795 hashed. This way we can access the Client ID from the cache
5796 with Client ID but with the hash of the ID (which is a hash of
5797 the nickname) as well without any difference in performance.
5799 Added also silc_idcache_find_by_id_one_ext to do one on one
5800 searching when we have the actual ID. Added also function
5801 silc_hash_client_id_compare. The affected files are
5802 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5804 * When hashing the name associated with a ID it is always done
5805 in lowercase. This way we can access the cache without worrying
5806 about case-sensitivity, even though, for example nicknames are
5809 * Fixed a bug in server with channel message sending. It put
5810 wrong ID type as destination ID. The affected file
5811 silcd/packet_send.c.
5813 * silc_idcache_del_by_context now deletes from all hash tables
5814 by context. Affected file lib/silccore/idcache.c.
5816 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5818 * Changed the client library to use the new ID Cache interface.
5819 Changes around the source tree.
5821 * Added silc_hash_table_rehash_ext to rehash with specific
5822 hash function. Affected file lib/silcutil/silchashtable.[ch].
5824 * Added silc_hash_string_compare to compare two strings in the
5825 hash table. Affected file lib/silcutil/silcutil.[ch].
5827 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5829 * Added new function silc_idcache_del_by_context into the
5830 lib/silccore/idcache.[ch].
5832 * Changed the server's ID list routines to use the new ID Cache
5833 interface. Changes around the source tree.
5835 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5837 * Added silc_hash_table_del[_by_context]_ext functions in to the
5838 lib/silcutil/silchashtable.[ch].
5840 Removed silc_hash_table_find_all* routines and added new
5841 silc_hash_table_find_foreach to replace them.
5843 Added silc_hash_table_replace_ext function as extended
5844 replacing function. Separated the simple hash table interface
5845 from the extended hash table interface in the file
5846 lib/silcutil/silchashtable.h.
5848 * Fixed minor bugs and changed it to use some of the new
5849 hash table functions in lib/silccore/idcache.c
5851 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5853 * Added new function silc_hash_table_find_all to return all keys
5854 in the hash table by the specified key. As the hash table is
5855 collision resistant it also makes it possible to have several
5856 duplicate keys in the hash table. This function may be used to
5857 find all of the keys from the hash.
5859 Added user_context arguments to the SilcHashFunction,
5860 SilcHashCompare and SilcHashDestructor to deliver user specified
5863 Added new fuctions silc_hash_table_find[_all]_ext to do
5864 extended lookup with specified hash and compare functions and
5865 specified user contexts.
5867 Added new function silc_hash_table_add_ext to add the key
5868 with specified hash function and user context.
5870 Added new function silc_hash_table_foreach to traverse all
5871 entrys in the hash table. Added SilcHashForeach callback
5874 Added new function silc_hash_table_del_by_context to delete
5875 the entry only if the context associated with the key matches.
5877 Affected files are lib/silcutil/silchashtable.[ch].
5879 * Removed silc_hash_[server/client/channel]_id and added just
5880 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5881 silc_hash_id_compare to compare two ID's using as the hash table
5882 comparison function. Added also silc_hash_data to hash
5883 binary data and silc_hash_data_compare to compare it.
5885 * Removed silc_idlist_find_client_by_hash as it is not needed
5886 anymore. Affected file silcd/idlist.[ch].
5888 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5889 to use internally the SilcHashTable. The new ID Cache is a lot
5890 faster than the old one. Some of the ID Cache interface was also
5891 rewritten and obsolete and stupid functions were removed.
5893 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5895 * Added entry_count field to the SilcHashTable to keep the number
5896 of the entries in the table. Implemented the function
5897 silc_hash_table_rehash. Added new function
5898 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5900 Fixed a minor bug in silc_hash_table_free.
5902 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5903 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5904 into the lib/silcutil/silcutil.[ch].
5906 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5908 * Implemented a collision resistant hash table into the
5909 lib/silcutil/silchashtable[ch]. See the header and the source
5910 for the SilcHashTable API.
5912 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5914 * Merged dotconf version 1.0.2 into lib/dotconf.
5916 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5918 * Do not compile anything in lib/silcsim/* if the SIM support
5919 is not enabled. The tree should now compile without problems
5922 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5924 * Compiled the SILC under cygwin. Compiled and tested briefly
5925 without problems. More tests needed. The SIMs didn't compile
5928 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5930 * Fixed possible crash in silc_get_username in the
5931 lib/silcutil/silcutil.c.
5933 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5935 * Fixed a va_arg in silc/client_ops.c.
5937 * Oops, RC5 routines were named AES and caused some problems
5938 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5940 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5942 * Added new SilcIDIP structure into the lib/silccore/id.h and
5943 replaced the old `ip' fields from all SILC ID's to that type.
5944 This is a step towards IPv6 support.
5946 The silc_id_get_len takes now the ID as an extra argument.
5947 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5948 both IPv4 and IPv6 based ID's.
5950 The affected files are lib/silccore/id.[ch] and other files
5951 around the tree using these routines.
5953 * Removed the ID length arguments in server from various
5954 silc_server_send_notify_* routines -> they are not needed
5957 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5959 * Fixed memory leak in silc_encode_pem_file in the file
5960 lib/silcutil/silcutil.c.
5962 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5964 * Check minor version as well in the SKE. Affected files are
5965 silcd/protocol.c and lib/silcclient/protocol.c.
5967 * Added --identifier option to the server so that an identifier
5968 can be when creating the public key for the server. Affected
5969 file is silcd/silcd.c.
5971 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5972 lib/silccrypt/silcpkcs.c.
5974 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5976 * Register default ciphers and stuff when using -C option with
5977 the server. Affected file sildc/silcd.c.
5979 * Put back the servers public key filename format, it is better
5980 than the new one. For now, the client keys are saved with the
5981 new filename format. The affected file silc/client_ops.c.
5983 * Implemented the Cipher API for the rest of the ciphers that
5984 did not implement it or implemented it the wrong way.
5986 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5988 * Register default ciphers and stuff when using the -S option
5989 in the client. Affected file silc/silc.c. Same also when
5990 creating new key pair with -C option.
5992 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5994 * Fixed the silc_verify_public_key client operation function to
5995 save the public keys differently. The fingerprint is now
5996 used as filename and not the hostname. This way also the
5997 client keys are saved uniquely and not with hostnames. The
5998 affected file is silc/client_ops.c.
6000 * Trimmed the silc_hash_fingerprint function to remove extra
6001 whitespaces from the end of the fingerprint. The affected
6002 file is lib/silccrypt/silchash.c.
6006 * Added silc_cipher_register_default function to register all
6007 default ciphers. It can be used when configuration files
6008 does not exist and the application does not want any specific
6009 ciphers in any specific order.
6011 The SilcDList is now used as silc_cipher_list dynamically
6012 allocated cipher list. Removed the static list all together
6013 and now all ciphers must be allocated to the dynamic list.
6014 The silc_cipher_alloc routine was changed to check only the
6017 All silc_cipher_* routines that used to return int returns
6020 The affected files lib/silccrypt/silccrypt.[ch].
6022 * The same thing was done to silc_hash_* as for silc_cipher_*
6023 routines. Affected files lib/silccrypt/silchash.[ch].
6025 * The same thing was done to silc_pkcs_* as for silc_cipher_*
6026 routines. Affected files lib/silccrypt/silcpkcs.[ch].
6027 Added also silc_pkcs_[un]register[_default] functions.
6028 Removed the data_context from the PKCS API.
6030 * Added silc_hmac_register_default function to register default
6031 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
6032 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
6033 to unregister all hmacs at once.
6035 * Register the default ciphers, hash functions, PKCSs and HMACs
6036 if client's configuration file does not exist. The affected
6039 * The client did not load the hash functions from the SIM
6040 modules at all. Added support for this. Affected file is
6041 silc/clientconfig.c.
6043 * When decoding public key with silc_pkcs_public_key_decode, check
6044 the supported algorithm only if PKCS are registered. Affected
6045 file lib/silccrypt/silcpkcs.c. The same was done with the
6046 silc_pkcs_private_key_decode.
6048 * Fixed the SILC List routines to keep the list always in order.
6049 It used to change the list's order when traversing the list but
6050 not it preserves the order. Affected file lib/trq/silclist.h.
6052 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6054 * Added the client library to use the SilcSocketConnection's
6055 reference counter (by silc_socket_dup) to prevent the bug that
6056 the socket object may be freed underneath async operation.
6058 * The name resolv library checking fixes in the configure.in.pre.
6061 * Created new version of the protocol drafts for future
6062 development. The -03 drafts are the ones that will be changed
6063 in the trunk now and the -02 will remain as they are.
6065 * Send list of CUMODE notifys to the router when announcing
6066 the channel users to the router. Affected file silcd/server.c.
6067 If the router receiving channel founder CUMODE for a channel
6068 that already has channel founder it will send CUMODE notify
6069 to the sender to remove the channel founder rights from the
6070 announced client. Affected file silcd/packet_receive.c.
6072 * The CUMODE notify may now use Server ID as well as the entity
6073 who changes the mode. Updated protocool specs.
6075 * Updated INSTALL and README files.
6077 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6079 * New web pages in the http://silc.pspt.fi. The pages was
6084 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6086 * Implemented the [DenyConnectin] config section in the server.
6087 Added silc_server_config_denied_conn to check whether incoming
6088 connection is denied. Affected file silcd/serverconfig.[ch].
6090 * Do not check the ports when checking the incoming configuration
6091 data if the port is 0, meaning any. Affected file is
6092 silcd/serverconfig.c.
6094 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6096 * Fixed buffer overflow in silc_string_compare in the file
6097 lib/silcutil/silcutil.c.
6099 * Fixed double free in silc_server_command_leave in the file
6102 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6104 * Fixed the version checking in the server. Affected file is
6107 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6109 * Fixed the configuration data fetching when accepting new
6110 connections in the server. Affected file silcd/server.c.
6112 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6114 * Added `sender_entry' argument to the function
6115 silc_server_packet_relay_to_channel so that we can check
6116 whether some destination actually belongs to the same route
6117 the sender belongs (ie, we must not resend the packet to the
6118 sender). Affected file silcd/packet_send.[ch].
6120 * Added `servername' field to the SilcClientEntry in the server
6121 to hold the name of the server where client is from. Affected
6122 file is silcd/idlist.h.
6124 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6126 * Moved the channel message encrypting in the router betwen
6127 router connections from silc_server_channel_message to the
6128 silc_server_packet_relay_to_channel since we want to check
6129 whether we have anybody channel before encrypting anything.
6130 Affected files silcd/packet_[receive/send].c.
6132 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6134 * Fixed the [AdminConnection] server config section to support
6135 multiple entries. Affected file silcd/serverconfig.c.
6137 * Added support into the server to check the validity of the
6138 incoming connection before executing any KE or authentication
6141 * The connection configuration is now saved to the KE and
6142 connection auth protocol contexts and not fetched anymore in
6143 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
6145 * The local hosts listenning address and port is also resolved
6146 now when starting the server. We want to have the socket object
6147 to include the real address and port for the listener. Added
6148 new function silc_net_check_local_by_sock into the files
6149 lib/silcutil/silcnet.[ch].
6151 * Fixed a broadcast bug in server -> do not broadcast if we
6154 * Fixed a routing bug. Do not route broadcast packets ever.
6155 Broadcast packets must be processed always and not routed since
6156 they may be destined to some other host than yourself and thus
6157 would get routed without no good reason. Affected file is
6160 * Added function silc_server_config_is_primary_route to check
6161 whether primary router connection has been configured (a router
6162 configuration that we are initiating). If there is not, we
6163 will assume that there is only two routers in the SILC network
6164 and we will use the incoming router connection as our primary
6165 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
6167 * Changed the order of the broadcasting. Broadcast _after_ the
6168 packet has been processed not before. Affected file is
6171 * Fixed a [ClientConnection] parsing bug. The port was never
6172 parsed correctly thus resulting to port 0. Affected file
6173 silcd/serverconfig.c.
6175 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
6176 argument and did not set the broadcast packet flag. Affected
6177 file silcd/packet_send.c. Fixed same bug in the function
6178 silc_server_send_notify as well.
6180 * If we receive NEW_ID packet for our own ID in the server, ignore
6183 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6187 * Removed the nickname from the Private Message Payload.
6188 Updated the code and the protocol specs.
6190 * Updated protocol specs for submitting to the IETF.
6192 * Tweaked the Random Number Generator a bit. Affected file
6193 lib/silccrypt/silcrng.c. Exported a new function
6194 silc_rng_[global]_add_noise which can be used to add more
6197 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6199 * Do not parse packets with different timeout when protocol
6200 is active -> may cause problem with rekey. Affected file
6203 * When server receives signoff notify it must not create
6204 new channel key if the client is on any channels since the
6205 sender of the signoff notify will create it.
6207 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6209 * Added printing of error messages during SKE protocol from the
6210 failure packet sent by server during SKE. Affected file
6213 * Removed the client's failure_callback handling with timeout
6214 and handle it immediately when received.
6216 * The SKE library returned wrong type in SUCCESS and FAILURE
6217 packets. They must be 32 bit MSB not 16 bit MSB.
6219 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6221 * Ok, rewrote the logic of the re-key and now it seems to work.
6222 I tested it on high traffic with frequent re-keys without
6223 problems. Added hmac_receive (and renamed hmac to hmac_send)
6224 in SilcClientConnection in lib/silcclient/client.h and
6225 in SilcIDListData in silcd/idlist.h. Also, removed the
6226 SilcPacketParserContext's cipher and hmac fields as they are
6227 not needed anymore and actually caused some problems when
6228 the ciphers and hmac's changed underneath the packet parser.
6230 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6232 * If re-key protocol is active then process the incoming packets
6233 synchronously since we must assure that icoming packets encrypted
6234 with the old key is processed before the new keys is set to
6235 use. This is true other packets than for REKEY packets.
6236 Affected file silcd/server.c. The same was done to client library
6237 as well, affected file lib/silcclient/client.c.
6239 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6241 * Fixed bug in client and server to accept the force send if
6242 the packet is send from silc_[server/client]_packet_process
6243 function. Otherwise the packets are never delivered, oops.
6245 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6247 * Disable force sending of packets when REKEY protocol is active.
6248 We must assure that no packet is sent directly when rekey is
6249 performed. All packets must be sent through packet queue.
6250 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
6251 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
6252 function is silc_[server/client]_packet_send_real to check
6255 * Replaced the SIM paths from example config files to
6256 /usr/local/modules. Also, make install creates now
6257 /usr/local/silc/logs directory to hold all the SILC server
6260 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6262 * Made the configure.in.pre work on Solaris. Patch by salo.
6264 * Made all ciphers compatible with non-x86 machines. Defined
6265 CBC mode macros into lib/silccrypt/ciphers_def.h.

6271 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6273 * When MAC computation fails the silc_packet_decrypt returned 0
6274 even though it was supposed to return -1. Fixed this. The
6275 affected file is lib/silccore/silcpacket.c.
6277 * Do not replace the config files in /etc/silc (in make install)
6278 if they already exist. Affected file ./Makefile.am.
6280 * Do not send re-key packets immediately but through packet queue.
6281 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6283 * Changed silc_net_check_host_by_sock to return FALSE if the
6284 IP/DNS could not be resolved. Though, it returns the IP address
6285 now even if it could not resolve it (but returns also FALSE).
6286 Affected file lib/silcutil/silcnet.[ch].
6288 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6290 * Added silc_pkcs_decode_identifier to decode the public key's
6291 identifier. Affected file lib/silccrypt/silpkcs.[ch].
6292 Added also silc_pkcs_free_identifier. Added also new context
6293 SilcPublicKeyIdentifier.
6295 * Added -S option to the silc client. It is used to dump the
6296 contents of the specified public key file.
6298 * Changed the PKCS api to return the public key length when
6299 setting the public key.
6301 * Fixed a fatal bug in the public and private key file loading.
6302 Affected file lib/silccrypt/silcpkcs.c.
6304 * Execute the packet parsing for client with zero (0) timeout
6305 if the protocol is active. Affected file silcd/server.c.
6307 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6309 * Made the key generation options to the silcd program. Added
6310 -C option, equivalent to client's option.
6312 * Added new [ServerKeys] config section to the server. It
6313 configures the server's public and private key.
6315 * Defined generic Public Key Payload into the protocol
6316 specification to send specific type of public keys and
6319 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6320 public key or certificate.
6322 * Implemented the GETKEY command to the server and to the
6323 client library and on user interface.
6325 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6327 * Made preliminary `make install' work.
6329 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6331 * Added SilcServerRekey context into silcd/idlist.h.
6333 * Added the PFS support as defined in the specification to the
6334 SKE protocol. Affected files lib/silcske/*.c.
6336 * Added `ske_group' field to the SilcServerRekey context to hold
6337 the number of the SKE group that is used with PFS in re-key.
6338 Affected file silcd/idlist.h.
6340 * Added PFS re-key support to the server. Affected file is
6343 * Added silc_protocol_cancel to cancel execution of the next
6344 state of the protocol. Affected file is
6345 lib/silccore/silcprotocol.[ch].
6347 * Added the re-key support with and without PFS to the client
6348 library. Re-key is performed once in an hour, by default.
6350 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6351 Added silc_client_rekey_callback and silc_client_rekey_final.
6352 Affected files are lib/silcclient/protocol.[ch] and
6353 lib/silcclient/client.[ch].
6355 * Removed the `hmac_key' and `hmac_key_len' fields from the
6356 SilcClientConnection structure; not needed. Affected file is
6357 lib/silcclient/client.h.
6361 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6363 * Do not ask whether user wants to use the negotiated private key
6364 for private messages, just use it. Affected file is
6365 silc/local_command.c.
6367 * Added `send_enc_key' and `enc_key_len' fields to the
6368 SilcIDListData structure since they are needed in the re-key
6369 phase. Affected file is silcd/idlist.[ch].
6371 * Implemented the simple re-key protocol into the server.
6372 Affected files silcd/server.c and silcd/protocol.[ch]. The
6373 re-key will be performed once in an hour, by default.
6375 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6376 Added silc_server_rekey, silc_server_rekey_callback and
6377 silc_server_rekey_final.
6379 * Removed Tunneled flag from the protocol. Updated the code
6380 and the specifications.
6382 * Adde `pfs' field to the SilcIDListData to indicate whether
6383 the PFS is to be performed in the re-key. Affected file is
6386 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6388 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6389 int64 of at least the xintXX size. If void * is less that 4
6390 bytes uint32 * will be used. Defined bool as boolean.
6392 * Changed _ALL_ unsigned long and unsigned int to uint32,
6393 unsgined short to uint16 in the source tree.
6395 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6396 not handle clients that has entry->data.registered == FALSE.
6397 They are not in the network anymore. Affected file is
6400 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6402 * Implemented the sending of the SERVER_SIGNOFF notify in the
6403 server. Affected file is silcd/server.c.
6405 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6406 Added also silc_notify_payload_encode_args into the
6407 lib/silccore/silcnotify.[ch].
6409 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6410 Affected file silcd/packet_receive.c.
6412 * Implemented the SERVER_SIGNOFF notify handling in the client
6413 library. Affected file lib/silcclient/client_notify.c. Also,
6414 implemnted the printing of the SERVER_SIGNOFF info to the
6415 application. Affected file silc/client_ops.c.
6417 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6418 if the deleting was successful. Affected file silcd/idlist.[ch].
6420 * Added support for public key authentication in the connection
6421 authentication protocol in the client library. Affected file
6422 lib/silcclient/protocol.c.
6424 * Changed the server's silc_idlist_get_clients_by_* interface
6425 to support already allocated array so that new entries may be
6426 added to pre-allocated array. Affected file silcd/idlist.[ch].
6427 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6428 and command replies.
6430 * All command reply functions in the server now calls the
6431 pending command callback even if error occured. This way the
6432 error will be delivered to the client as well. Affected files
6433 silcd/command.c and silcd/command_reply.c.
6435 * Fixed INFO command to return local server's info if no server
6436 was provided. Affected file lib/silcclient/command.c.
6438 * Removed RESTART command for good. Updated the code and the
6441 * Rewrote parts of the task system. It is a bit simpler now.
6442 Removed unsued task priorities. The affected files are
6443 lib/silcutil/silctask.[ch].
6445 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6447 * Moved the USERS printing from the library to the application.
6448 Affected files lib/silcclient/command.c and silc/client_ops.c.
6450 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6454 * Added channel key re-key support. The re-key is perfomed
6455 only by the router and is done once in an hour. Added `rekey'
6456 field to the SilcChannelEntry in the server. Affected files
6457 silcd/server.c and silcd/idlist.h.
6459 * Added silc_task_unregister_by_context into the file
6460 lib/silcutil/silctask.[ch].
6462 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6464 * Added SILC_UMODE_GONE mode to indicate when the client is not
6465 present in the SILC network. Added also support to the local
6466 command AWAY that will set this mode. Added support of showing
6467 "xxx is gone" in WHOIS command. The USERS command shows the
6468 gone status as well.
6470 * Fixed setting server and router operator privileges in the
6471 server's UMODE command. Affected file silcd/command.c.
6473 * Merged the SKE KE1 and KE2 payloads into one payload. The
6474 new KE payload is equivalent to the old KE2 payload.
6476 Cleaned up the SKE Start Payload parsing. It now uses the
6477 simple buffer unformatting to do the parsing. A lot faster
6480 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6481 to the SKE that is used to indicate whether both of the SKE
6482 parties should perform authentication. By default only the
6483 responder performs authentication. By setting this flag also
6484 the initiator must do authentication. By default it is unset
6485 since in normal SKE case, client to server connection, only
6486 the responder should do authentication. When doing SKE between
6487 two clients both should perform authentication. Updated the
6488 code and the protocol specs.
6490 * A little fix to IDENTIFY command in the server. Search the
6491 client first by hash not nickname. Affected file is
6494 * Fixed the silc_client_close_connection to support closing
6495 the client to client connections wihtout deleting too much
6496 data. Affected file lib/silcclient/client.c.
6498 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6499 are received if protocol used to be active but is not anymore
6500 the application would crash due to NULL pointer dereference.
6501 Affected files silcd/server.c and lib/silcclient/client.c.
6503 * Added `hash' field to the SilcClientConnection to include
6504 the hash function negotiated in the SKE protocol.
6506 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6507 to set the channel founder authentication data. A client can
6508 claim the founder rights later by providing the authentication
6509 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6510 This way the channel founder can regain the channel founder
6511 privileges even it is left the channel. This works only on
6512 local server and the client must be connected to the same
6513 server to be able to regain the founder rights. Updated the
6514 protocol specs accordingly.
6516 Added support to the CMODE command in the client to set the
6517 founder auth data. Read the README to see how to set it.
6519 Added support to the CUMODE command to claim the founder
6520 rights. Read the README to see how to do it.
6522 Added support for the founder authentication to the Channel
6523 Entry in the server. Affected file silcd/idlist.h.
6525 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6526 server's CMODE command. Affected file silcd/command.c.
6528 * Added the following new functions into lib/silccore/silcauth.[ch]:
6529 silc_auth_get_method and silc_auth_get_data.
6531 * The server now saves the remote hosts public key to the
6532 SilcIDListData pointer. Affected file silcd/protocol.c.
6534 * The normal server now does not remove the channel entry from
6535 the cache if the founder authentication data is set. It used
6536 to remove it if the founder was the last one on the channel on
6537 the server and left the channel. The auth data is saved and
6538 if the channel is re-joined later the old entry is used with
6539 the old auth data. Affected files silcd/command_reply.c and
6542 * Removed the `pkcs' field from the SilcIDListData structure
6543 in the server; it is not used. Affected file silcd/idlist.h.
6545 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6547 * Fixed packet processing on slow links. Partial packets were
6548 never re-processed because the incoming data buffer was cleared
6549 by the application. Application must not directly clear the
6550 sock->inbuf, the packet processing routines handle it. Fixed
6551 this in client library and in server.
6553 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6555 * Fixed the WHOIS and IDENTIFY send reply function to really
6556 check whether to send list or just one entry. Affected file
6559 * Cleaned up the LEAVE command's channel key distribution. The
6560 affected file silcd/command.c.
6562 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6563 can enforce the channel mode as well. In that case the ID
6564 includes the ID of the server. The code now enforces the
6565 mode change if the router have different mode than the server.
6567 * The notify client operation with CMODE_CHANGE notify can now
6568 return NULL client_entry pointer if the CMODE was not changed
6569 by client. Application must check for this.
6571 * Added <Server ID> argument to INFO command to support server
6572 info fetching by Server ID.
6574 * Added silc_server_announce_get_channel_users to get assembled
6575 packets of channel users of the specified channel. Affected
6576 file silcd/server.[ch].
6578 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6579 was freed underneath the ID Cache.
6581 * Re-announce clients when the server received CHANNEL_CHANGE
6582 notify from the router. Affected file silcd/packet_send.c.
6584 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6586 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6587 crashed since it did not handle the fact that there is no cipher
6588 called "3" and didn't check the error condition. Now fixed.
6590 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6591 flag. It can be used to send message requests.
6593 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6595 * Implemented the RESTART command in the client.
6597 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6598 notice type messages. Added notice printing to the user
6601 * The channel keys are not re-generated if the channel's mode
6602 is PRIVKEY, ie private key on the channel exists. Affected
6603 files silcd/server.c and silcd/command.c.
6605 * Fixed a little bug in channel message delivery when channel
6606 private keys are set in the server. Affected file is
6607 silcd/packet_send.c.
6609 * Changed the setting on channel->on_channel = TRUE from the
6610 silc_client_save_channel_key to the JOIN command reply. The
6611 key payload is not received if the private channel key is set.
6612 Affected file lib/silcclient/command_reply.c and the
6613 lib/silcclient/client_channel.c.
6615 * When the CMODE_CHANGE notify is sent and the channel private
6616 key mode is removed the channel key must be re-generated in
6617 other cells as well. Added this support for the router in the
6618 silcd/packet_receive.c.
6620 * Added new local command NOTICE to send notice message on
6621 channel. Affected file silc/local_command.[ch].
6623 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6625 * Added new local command ME to the client. It is used to send
6626 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6627 some action. Affected file silc/local_command.[ch].
6629 * Changed channel_message and private_message client operations
6630 to deliver the message flags to the application. Added also
6631 the `flags' arguments to the silc_client_send_channel_message
6632 and silc_client_send_private_message functions. Affected file
6635 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6637 * Redefined the Private Message Payload to support private message
6638 keys and to support the new private message flags. Updated
6639 the protocol specs. Flags makes it possible to have for example
6640 CTCP style messages.
6642 * Added new type SilcPrivateMessagePayload and defined an API
6643 for it in the lib/silcclient/silcprivate.[ch].
6645 * Tested private message private keys successfully. Tested the
6646 private message key set, unset and list commands with the new
6649 * Redefined the Channel Message Payload to include the channel
6650 message flags (equal with private message flags) to support
6651 for example CTCP style messages.
6653 * Defined some of the message (for channel and private message)
6654 flags. Updated the protocol specs and added the flags to the
6655 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6657 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6659 * Added SilcKeyAgreementStatus type to the key agreement routines
6660 to indicate the current status and error if one occured.
6661 The status types are defined in the lib/silcclient/silcapi.h.
6663 * Added new local command KEY that is used to set and unset private
6664 keys for channels, set and unset private keys for private messages
6665 with remote clients and to send key agreement requests and
6666 negotiate the key agreement protocol with remote client. The
6667 key agreement is supported only to negotiate private message keys,
6668 it currently cannot be used to negotiate private keys for channels,
6669 as it is not convenient for that purpose.
6671 * Fixed a minor pending callback setting bug in the function
6672 silc_client_get_client_by_id_resolve, now the function works.
6673 Affected file lib/silcclient/idlist.c.
6675 * Added function silc_net_get_local_port to get local bound
6676 port by socket. Added to lib/silcutil/silcnet.[ch].
6678 * Added `sockets' and `sockets_count' fields to the SilcClient
6679 object. They hold the sockets of the listenning sockets in
6680 the client. Listenning sockets may be for example the key
6681 agreement server. Affected file lib/silcclient/client.[ch].
6682 Added functions the silc_client_add_socket and the
6683 silc_client_del_socket. They are exported to the application
6686 * Added ~./silc/clientkeys to support other client's public keys.
6688 * Renamed verify_server_key client operation to verify_public_key
6689 and added one argument to indicate the type of the connection
6690 (server, client etc.).
6692 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6694 * Added silc_server_connection_auth_request to handle the
6695 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6696 silcd/packet_receive.[ch].
6698 * Added silc_server_send_connection_auth_request into the
6699 silcd/packet_send.c to send the connection auth request packet.
6701 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6704 * Fixed the public key authentication in responder side in the
6705 server. The `auth_data' pointer includes the SilcPublicKey
6706 not the path to the public key. Affected file silcd/protocol.c.
6708 * Implemented the public key authentication in the initiator side
6709 in the server. Affected file silcd/protocol.c.
6711 * Removed the [RedirectClient] config section from the server
6712 configuration. Is not needed and I don't want to implement it.
6714 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6716 * Cleaned up the CMODE command in the server. It now works
6717 correctly and supports all the modes defined in the protocol.
6718 Affected file is silcd/command.c.
6720 * Added `hmac_name' field to the SilcChannelEntry in the server
6721 to hold the default HMAC of the channel. It can be set when
6722 creating the channel (with JOIN command). Affected files
6725 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6726 type to indicate the change of the current cipher and hmac
6727 on the channel. Client can safely ignore the <cipher> argument
6728 (if it chooses to do so) since the CHANNEL_KEY packet will
6729 force the channel key change anyway. The <hmac> argument is
6730 important since the client is responsible of setting the new
6731 HMAC and the hmac key into use.
6733 * Fixed the CMODE command in the client library as well.
6735 * Tested CMODE command in router environment successfully.
6737 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6739 * Show the version of the remote client (or server) when connecting
6740 to the server. It is logged to the log file. Affected file
6741 is silcd/protocol.c.
6743 * Fixed the KILLED notify handling in the client library. The
6744 client must be removed from all channels when receiving the
6747 Also, do not remove the client entry when giving the KILL
6748 command but when the KILLED notify is received.
6750 * Removed silc_idlist_find_client_by_nickname from the server.
6751 Not needed anymore. Affected files silcd/idlist.[ch].
6753 * Implemented the CHANNEL_CHANGE notify type handling to the
6754 server. Affected file silcd/server.c.
6758 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6760 * Added silc_server_send_notify_invite to send the INVITE
6761 notify between routers.
6763 * Implemented the INVITE command correctly to the server.
6765 * Implemented the INVITE notify type handling in the server.
6767 * Implemented the INVITE command to the client library and on the
6770 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6772 * Added function silc_server_get_client_resolve to find the
6773 client entry by ID from all ID lists and then resolve it
6774 (using WHOIS) if it cannot be found. Affected file is
6777 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6779 * Implemented the BAN command to the client library.
6781 * The JOIN command in the server now checks the invite list
6784 * Changed the silc_command_reply_payload_encode_va and the
6785 silc_command_payload_encode_va to support that if argument is
6786 NULL it ignores and checks the next argument. Affected file
6787 lib/silccore/silccommand.c.
6789 * Added silc_server_send_notify_ban to send the BAN notify
6790 type between routers.
6792 * Chaned the silc_notify_payload_encode to support that if
6793 argument is NULL it ignores and checks the next argument.
6794 Affected file lib/silccore/silcnotify.c.
6796 * Tested ban lists in router environment successfully.
6798 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6800 * Implemented BAN command to the server, in silcd/command.[ch].
6802 * Removed the BAN and INVITE_LIST modes from the CMODE command
6805 * Added function silc_string_match to regex match two strings.
6806 Affected files lib/silcutil/silcutil.[ch].
6808 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6810 * Redefined parts of the SilcChannelEntry in the server to support
6811 the new ban and invite lists.
6813 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6815 * Redefined the INVITE command. The same command can be used to
6816 invite individuals to the channel but also to manage the invite
6817 list of the channel (to add to and remove from the invite list).
6818 Updated the protocol specs.
6820 * Added new command SILC_COMMAND_BAN that can be used to manage
6821 the ban list of the channel. Updated the protocol specs.
6823 * Removed the channel modes: the SILC_CMODE_BAN and the
6824 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6825 in the CMODE command. The equivalent features are now available
6826 using INVITE and BAN commands. Updated the protocol specs.
6828 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6829 in the network about change in the current ban list. The notify
6830 type is not used by the client.
6832 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6833 support the invite lists.
6835 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6837 * Added new function silc_string_regexify that converts string
6838 including wildcard characters into regex string that can
6839 be used by the GNU regex library. Added into the file
6840 lib/silcutil/silcutil.[ch].
6842 Added silc_string_regex_combine to combine to regex strings
6843 into one so that they can be used as one regex string by
6844 the GNU regex library. Added into the file
6845 lib/silcutil/silcutil.[ch].
6847 Added silc_string_regex_match to match two strings. It returns
6848 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6850 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6852 * Imported GNU regex to the soruce tree into lib/contrib.
6853 Fixed some compiler warning from the regex.c.
6855 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6857 * Fixed MOTD command in the server to work in router environment.
6859 * Fixed the MOTD command in the client library to support
6860 the server argument in the command.
6862 * Added `nickname_len' argument to the silc_idlist_add_client
6863 in the server, as the `nickname' argument may be binary data
6866 * Added silc_idlist_get_channels to return all channels from
6869 * Implemented LIST command to the server. Affected file is
6872 * Implemented the LIST command to the client library and on the
6875 * Added [<user count>] argument to the LIST command reply.
6876 With private channels the user count is not shown.
6878 * Updated TODO and README.
6880 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6882 * The client entry's data.registered must be TRUE even with
6883 global client entry on global client list. The data.registered
6884 is used to check whether the client is anymore in the network,
6885 for example with WHOWAS command so it must be valid.
6887 * Fixed the WHOWAS command in the server. It now actually works
6888 in router environment. Added function into silcd/command_reply.c
6889 silc_server_command_reply_whowas_save.
6891 * Added silc_idlist_purge function to the silcd/idlist.c
6892 to periodically purge the ID Cache.
6894 * Fixed INFO command in the server. It works now in router
6895 environment. Added <server name> argument to the INFO command
6896 reply. Updated the protocol specs.
6898 * Fixed minor bug in silc_idcache_purge to not purge if the
6899 expire value is zero.
6901 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6902 they were buggy because of the WHOWAS information.
6904 * Fixed local command MSG to handle the async resolving of
6905 the remote client properly. It used to fail the first MSG.
6906 Affected file silc/local_command.c.
6908 * Added `data_len' field to SilcIDCache context.
6910 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6912 * Update TODO. Todo in commands in the server.
6914 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6916 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6917 used by routers as broadcast packet to inform other routers
6918 about the changed user mode.
6920 Implemented the notify handling in the server. Affected file is
6921 silcd/packet_receive.c. Added the function
6922 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6924 * Added new generic Channel Payload and deprecated the New Channel
6925 Payload. The New Channel Payload is now the generic Channel
6928 * Added new argument `mode' to the silc_server_send_new_channel
6929 as it is required in the Channel Payload now.
6931 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6932 and created a new and real SilChannelPayload to represent the
6933 new generic Channel Payload. Implemented the encode/decode
6934 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6936 * Added silc_server_get_client_channel_list to return the list
6937 of channels the client has joined for WHOIS command reply.
6938 Affected file silcd/server.[ch].
6940 * Implemented the channel list sending in the WHOIS command reply
6941 in server and in the client.
6943 Implemented the channel list displaying on the user interface
6944 as well. Affected file silc/client_ops.c.
6946 * Added silc_channel_payload_parse_list to parse list of Channel
6947 Payloads. It returns SilcDList list of SilcChannelPayloads.
6948 Client for example can use this function to parse the list of
6949 channels it receives in the WHOIS command reply. The caller
6950 must free the list by calling silc_channel_payload_list_free.
6951 Affected files lib/silccore/silcchannel.[ch].
6953 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6955 * Added one new argument <user mode> to the WHOIS command reply
6956 to return the mode of the user in SILC. Updated the protocol
6959 Implemented it to the server and client.
6961 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6963 * Fixed the mode printing on the user interface on joining.
6964 Affected file silc/client_ops.c.
6966 * Implemented the UMODE command and user modes in general to the
6967 client library and to the user interface.
6969 * Implemented the UMODE command to the server.
6971 * The server now sends UNKNOWN_COMMAND error status if client sends
6972 unknown command. Affected file silcd/command.c.
6974 * All server commands now handle the command identifier the right
6975 way when sending the command reply to the client. The client can
6976 use to identify the command replies with the identifier.
6978 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6980 * Added silc_server_get_client_route to resolve the route to
6981 the client indicated by the client ID. Affected file is
6984 * Added silc_server_relay_packet as general function to relay
6985 packet to arbitrary destination. This deprecates functions
6986 like _send_private_message_key, _relay_notify etc. Affected
6987 file is silcd/packet_send.[ch].
6989 Removed silc_server_send_key_agreement,
6990 silc_server_send_private_message_key and
6991 silc_server_packet_relay_notify functions from the file
6992 silcd/packet_send.[ch].
6996 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6997 server. Affected file silcd/packet_receive.[ch].
6999 * Implemented the KILL command to the client. Implemented the
7000 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
7001 Affected files lib/silcclient/command[_reply].c and
7002 lib/silcclient/client_notify.c. Implemented the KILL notify
7003 printing in the user inteface.
7005 * Fixed a lot silc_parse_nick memory leaks from the client
7006 library in the file lib/silcclient/command.c.
7008 * Changed the silc_server_send_notify_on_channels's `sender'
7009 argument from SilcSocketConnection to SilcClientEntry to
7010 check the sender as entry and not as connection object and not
7011 to send to the client provided as argument. The affected file
7012 is silcd/packet_send.[ch].
7014 * The notify packets that are destined directly to the client used
7015 to not to be processed by the server. Now changed that and the
7016 server processes all notify packets. After relaying the packet
7017 to the client the notify packet is processed in the server.
7019 * The silc_server_free_client_data now checks whether there is
7020 pending outgoing traffic for the client and purges the data to
7021 the network before removing the client entry.
7023 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7025 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
7026 an client is killed from the SILC Network. Updated the protocol
7029 Added new function silc_server_send_notify_killed to the
7030 silcd/packet_send.[ch].
7032 * Added function silc_server_packet_relay_notify to relay notify
7033 packets that are destined directly to a client. In this case
7034 the server does not process the notify packets but merely relays
7035 it to the client. Affected file silcd/packet_send.[ch].
7037 Added also silc_server_packet_process_relay_notify to check
7038 whereto relay the notify. Affected file is
7039 silcd/packet_receive.[ch].
7041 * Implemented the KILL command to the server.
7045 * Added the backup schema desgined last fall to the protocol
7046 specs for everyone to see. The specification is in the
7047 *-spec-xx.txt draft and the packet type definitions for the
7048 backup routers is in *-pp-xx.txt draft. Thusly, added also
7049 new packet type SILC_PACKET_CELL_ROUTERS.
7051 * A big security problem in the implementation discovered. The
7052 signoff of an client did not cause new channel key generation
7053 which it of course should've done. The channel keys must be
7054 always re-generated when client leaves (or signoffs) the channel.
7055 The silc_server_remove_from_channels funtion now handles
7056 the channel key re-generation.
7058 * Added `sender' argument to the silc_server_send_notify_on_channels
7059 to not to send the client provided as argument. Affected file
7060 silcd/packet_send.[ch].
7062 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7064 * Implemented OPER and SILCOPER commands into the server and
7067 * Added silc_auth_verify and silc_auth_verify_data to verify
7068 the authentication directly from the authentication payload.
7069 It supports verifying both passphrase and public key based
7070 authentication. Affected file lib/silccore/silcauth.[ch].
7072 * Added `hash' field to the SilcIDListData structure. It is the
7073 hash negotiated in the SKE protocol. Affected file is
7076 * Slight redesigning of the SilcAuthPayload handling routines.
7077 Do not send SilcPKCS but SilcPublicKey as argument.
7079 * Implemented the public key authentication support to the
7080 serverconfig. The public key is loaded from the provided path
7081 and saved as authentication data to void * pointer. Thus,
7082 changed the unsigned char *auth_data to void *auth_data;
7084 * Fixed SHUTDOWN command to send the reply before the server
7085 is shutdown. :) Affected file silcd/command.c.
7087 * Fixed fatal bug in CONNECT command. The hostname was invalid
7088 memory and server crashed. Affected file silcd/command.c.
7090 * Fixed fatal bug in CLOSE command. The server_entry became
7091 invalid but was referenced later in the command. Affected file
7094 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7096 * Fixed fatal bug in failure packet handling. Server ignored
7097 the failure and thus crashed when it came.
7101 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7103 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
7104 that the command may be executed only once in (about) 2 seconds.
7105 The old SILC_CF_LAG flag is same but allows command bursts up
7106 to five before limiting.
7108 Added the support for CF_LAG and CF_LAG_STRICT flags to the
7109 server code. Various commands now includes the CF_LAG_STRICT
7110 flag to disallow any kind of miss-use of the command.
7112 * Fixed the silc_buffer_unformat to not to allocate any data
7113 if the length of the data is zero. It used to allocate the
7114 length + 1. Affected file lib/silcutil/silcbuffmt.c.
7116 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7118 * Changed the format of AdminConnection configuration section
7119 in the server. Added username of the admin to the format.
7120 Affected files silcd/serverconfig.[ch].
7122 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
7123 to return admin configuration data by host, username and/or
7126 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7128 * Implemented WHOWAS command to the server. Added the functions:
7130 silc_server_command_whowas_parse,
7131 silc_server_command_whowas_send_reply,
7132 silc_server_command_whowas_from_client and
7133 silc_server_command_whowas_from_server
7135 * Added <Client ID> argument to the WHOWAS command reply. Updated
7136 the protocol specs accordingly.
7138 * Implemented WHOWAS command and command_reply to the client
7141 Implemented the WHOWAS printing on the user interface.
7143 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7145 * Added new argument to the WHOWAS command reply, the real name.
7146 It is an optional argument. Updated the protocol specs.
7148 * Added SilcIDCacheDestructor callback that is registered when
7149 the SilcIDCache is allocated. The callback is called when
7150 an cache entry in the ID Cache expires, or is purged from the
7151 cache. Added into lib/silccore/idcache.[ch].
7153 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
7154 to destruct the client entries when the cache entry expires.
7155 Other ID Cache's in server and in the client library ignores
7158 * If the ID Cache entry's `expire' field is zero then the entry
7159 never expires. Added boolean `expire' argument to the
7160 silc_idcache_add function in the lib/silccore/idcache.[ch].
7161 If it is TRUE the default expiry value is used.
7163 * Added silc_server_free_client_data_timeout that is registered
7164 when client disconnects. By default for 5 minutes we preserve
7165 the client entry for history - for WHOWAS command.
7167 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7169 * Added support to the server to enforce that commands are not
7170 executed more than once in 2 seconds. If server receives
7171 commands from client more frequently, timeout is registered
7172 to process the commands. Affected file silcd/command.c.
7173 Added new function silc_server_command_process_timeout.
7175 * Changed NICK_NOTIFY handling in client library to check that
7176 if the client's nickname was changed, so there is no need to
7177 resolve anything from the server.
7179 * Removed error printing from the WHOIS and IDENTIFY commands.
7180 If error occurs then it is ignored silently in the client library.
7181 The application, however, may map the received error to
7182 human readable error string. The application currently maps
7183 the NO_SUCH_NICKNAME error to string.
7185 * Made the command status message public to the application. Moved
7186 them from lib/silcclient/command_reply.c to
7187 lib/silcclient/command_reply.h. The application can map the
7188 received command status to the string with the
7189 silc_client_command_status_message function.
7191 * Added check to the server to check that client's ID is same
7192 as the Source ID in the packet the client sent. They must
7195 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7197 * Added dist-bzip hook to the Makefile.am to make bzip2
7198 compressed distributions.
7200 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7202 * Server now enforces the maximum length for the nickname and
7203 the channel as protocol specification dictates. 128 bytes for
7204 nickname and 256 bytes for channel name.
7206 * Moved the WHOIS printing to the application. The client libary
7207 does not print out the WHOIS information anymore, the application
7208 must do it. Renamed silc_client_command_reply_whois_print to
7209 the silc_client_command_reply_whois_save.
7211 The client's idle time is also sent to the application now, and
7212 the idle is shown on screen.
7214 * Added silc_client_command_reply_identify_save to save the
7215 received IDENTIFY entries.
7217 * Do not check for channel private keys in message sending and
7218 reception if the channel does not have the PRIVKEY mode set.
7219 Affected file lib/silclient/client_channel.c.
7221 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7223 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
7224 just surfaced after chaning the JOIN procedure.
7226 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7228 * Added silc_client_get_clients_by_list to get client entries
7229 from Client ID list, that is returned for example by JOIN
7230 and USERS command replies. The application should use this
7231 function for example when JOIN command reply is received to
7232 resolve the clients already on the channel (library does not
7233 do that anymore as USERS command reply is not used in the JOIN
7234 procedure anymore). Affected files lib/silcclient/silcapi.h and
7235 lib/silcclient/idlist.c.
7237 * JOIN command reply and USERS command reply returns now SilcBuffer
7238 pointers instead of unsigned char pointers when returning
7239 the client list and mode list.
7241 * Added <Client ID> argument to the JOIN command reply, mainly
7242 for the server to identify for which client the command was
7243 originally sent. Updated protocol specs accordingly.
7245 * Added SilcDlist private_key pointer to the SilcChannelEntry
7246 in the client to support the channel private keys. Affected
7247 file is lib/silcclient/idlist.h.
7249 * Added SilcChannelPrivateKey argument to the function
7250 silc_client_send_channel_message so that application can choose
7251 to use specific private ke if it wants to. If it is not provided,
7252 the normal channel key is used, unless private keys are set.
7253 In this case the first (key that was added first) is used
7254 as the encryption key.
7256 * Implemented the support for channel private key handling.
7257 Implemented the following functions:
7259 silc_client_add_channel_private_key,
7260 silc_client_del_channel_private_keys,
7261 silc_client_del_channel_private_key,
7262 silc_client_list_channel_private_keys and
7263 silc_client_free_channel_private_keys
7265 Affected file lib/silcclient/client_channel.c.
7267 * Added the support for the private keys in the channel message
7268 sending and encryption and in the message reception and
7269 decryption. Affected funtions are
7270 silc_client_send_channel_message and silc_client_channel_message.
7272 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7274 * Added SKE's key verify callback to the client library's
7275 KE protocol context. Affected files lib/silcclient/protocol.[ch].
7277 * Removed the statement that server (or router) must send USERS
7278 command reply when joining to the channel so that the client
7279 knows who are on the channel. Instead, the client list and
7280 client's mode list is now sent in the JOIN command reply to the
7281 client who joined channel. This is better solution.
7283 * Added function silc_server_get_users_on_channel and function
7284 silc_server_save_users_on_channel to the silcd/server.[ch].
7286 * Removed function silc_server_command_send_users from the
7289 * Do not show topic on the client library anymore. The topic is
7290 sent in the command reply notify to the application and the
7291 application must show the topic now.
7293 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7295 * Added client searching by nickname hash into the IDENTIFY and
7296 WHOIS commands in the server as they were clearly missing from
7297 them. Affected file is silcd/command.c.
7299 * Fixed a bug in private message receiving in the client library.
7300 The remote ID was freed and it wasn't supposed, now it is
7303 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7305 * Minor fix to the channel payload; allocate the data area, as it
7306 needs to be of specific length.
7308 * If the key agreement port is zero then the operating
7309 system will define the bound port. Affected files are
7310 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7312 * Added new function silc_channel_payload_decrypt into the file
7313 lib/silccore/silcchannel.[ch].
7315 * Moved the channel message etc, check from silc_packet_decrypt
7316 to applications. The library calls now a generic
7317 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7318 when the packet is either normal or special. This was done to
7319 allow more wide range of checking that was not allowed when
7320 the code was in library. Now applications can do virtually any
7321 checks to the packet and return to the library the decision how
7322 the packet should be processed. Affected files are
7323 lib/silccore/silcpacket.[ch].
7325 Added silc_server_packet_decrypt_check to the server and
7326 silc_client_packet_decrypt_check to the client library.
7328 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7329 to send with specified source and destination information.
7331 * Channel message delivery between routers was broken after the
7332 channel key distribution was fixed earlier. The channel key
7333 was used be to distributed to other routers as well which is not
7334 allowed by the protocol. Now this is fixed and channel keys
7335 really are cell specific and the channel message delivery between
7336 routers comply with the protocol specification.
7338 * Fixed various commands in server to check also the global list
7339 for the channel entry and not just the local list. The affected
7340 file silcd/command.c.
7342 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7344 * Added assert()s to buffer formatting and unformatting routines
7345 to assert (if --enable-debug) when error occurs. Affected
7346 file: lib/silcutil/silcbuffmt.c.
7348 * Changed to auto-reconnect to check whether the remote host is
7349 router and register the re-connect timeout if it is. It used
7350 to check that whether we are normal server, but router must do
7351 auto-reconnect with another router as well. Affected file
7354 * Removed the [<key len>] option from CMODE command as the cipher
7355 name decides the key length, nowadays. See the defined ciphers
7356 from the protocol specification.
7358 * Added [<hmac>] option to the CMODE command to define the HMAC
7359 for the channel. Added SILC_CMODE_HMAC channel mode.
7361 * Added [<hmac>] option for the JOIN command so that user can
7362 select which HMAC is used to compute the MACs of the channel
7365 * Added Hmac field to the Channel Message Payload. The integrity
7366 of plaintext channel messages are now protected by computing
7367 MAC of the message and attaching the MAC to the payload. The
7368 MAC is encrypted. Now, it is clear that this causes some
7369 overhead to the size of the packet but rationale for this is that
7370 now the receiver can verify whether the channel message decrypted
7371 correctly and also when private keys are set for the channel the
7372 receiver can decrypt the packet with several keys and check from
7373 the MAC which key decrypted the message correctly.
7375 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7376 lib/silccrypt/silccipher.[ch].
7378 * Added silc_hash_len to return the digest length into the
7379 lib/silcrypt/silchash.[ch].
7381 * Rewrote parts of Silc Channel Payload interface in the
7382 lib/silccore/silcchannel.[ch]. The encode function now also
7383 encrypts the packet and parse function decrypts it.
7385 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7387 * Fixed a minor formatting bug in the SKE's key material processing.
7388 It actually might have processed the keys wrong way resulting
7391 * Redefined the mandatory HMAC algorithms and added new algorithms.
7392 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7393 and hmac-md5 truncated to 96 bits. The mandatory is now
7394 hmac-sha1-96. Rest are optional (including the one that used
7395 to be mandatory). Rationale for this is that the truncated HMAC
7396 length is sufficient from security point of view and can actually
7397 make the attack against the HMAC harder. Also, the truncated
7398 HMAC causes less overhead to the packets. See the RFC2104 for
7401 * Added new [hmac] configuration section. The SKE used to use
7402 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7403 is of course wrong. The official names that must be proposed in
7404 the SKE are the ones defined in the protocol specification
7405 (hmac-sha1-96 for example). The user can configure any hmac
7406 using any hash function configured in the [hash] section. At
7407 least, the mandatory must be configured.
7409 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7411 * Added HMAC list to the SKE proposal list. It has now both
7412 hash algorithm list and HMAC list. This makes the protocol
7413 incompatible with previous versions. The SKE now seems to work
7414 the way it is supposed to work, for the first time actually.
7416 * Defined plain Hash algorithms to the protocol specification.
7419 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7421 * Implemented support for key agreement packets into the server.
7422 Added functions silc_server_key_agreement and
7423 silc_server_send_key_agreement. Other than these functions,
7424 server has nothing to do with this packet.
7426 * Added support for private message key packets into the server.
7427 Added functions silc_server_private_message_key and
7428 silc_server_send_private_message_key.
7432 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7433 called in the protocol's final callback instead in the END
7434 protocol state. This makes a little more sense and in the same
7435 time in client we can use the same protocol routines for normal
7436 key exchange and to key agreement packet handling as well.
7438 * Added to both client's and server's KE protocol context the
7439 SilcSKEKeyMaterial pointer to save the key material. We will
7440 bring the key material to the protocol's final callback by doing
7441 this. The final callback must free the key material.
7443 * Added SKE's packet_send callback into client's KE protocol
7444 context so that the caller can choose what packet sending function
7445 is used. This way we can use different packet sending when
7446 doing normal SKE when doing key agreement packet handling (in
7447 the key agreement packet handling we do not want to encrypt
7450 * Implemented the responder side of the key agreement routines
7451 in the client. The client can now bind to specified port and
7452 accept incoming key negotiation. The key material is passed
7453 to the application after the protocol is over.
7455 * Implemented the processing of incoming Key Agreement packet
7456 in the client. Added function silc_client_key_agreement to
7459 * Implemented the intiator side of the key agreement routines
7460 in the client. The client can now initiate key agreement with
7461 another remote client. The key material is passed to the
7462 application after the protocol is over.
7464 * Created client_keyagr.c to include all the key agreement
7467 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7468 SILC_TASK_CALLBACK except that it is not static.
7470 * Created client_notify.c and moved the Notify packet handling
7471 from the client.[ch] into that file.
7473 * Created client_prvmsg.c and moved all private message and
7474 private message key routines from the client.[ch] into that file.
7476 * Create client_channel.c and moved all channel message and
7477 channel private key routines from the client.[ch] into that file.
7479 * Changed silc_client_get_client_by_id_resolve to resolve with
7480 WHOIS command instead of IDENTIFY command, in the file
7481 lib/silclient/idlist.c.
7483 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7485 * Implemented the SKE's responder side to the Client library.
7487 * When FAILURE is received to the protocol do not trust it
7488 blindly. Register a timeout to wait whether the remote closes
7489 the connection as it should do it, only after that process the
7490 actual failure. This was changed to both client and server.
7492 * Added client_internal.h to include some of the structures
7493 there instead of client.h in lib/silcclient/.
7495 * Added function silc_task_unregister_by_callback to unregister
7496 timeouts by the callback function.
7498 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7500 * Some "Incomplete WHOIS info" errors has been appearing on the
7501 log files. Took away the entry->userinfo check from WHOIS
7502 reply sending. The entry->userinfo is now " " if client did not
7503 provide one. I thought this was fixed earlier but something
7504 is wrong still. Let's see if the error still appears.
7506 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7508 * Fixed a minor bug in the login when the channel key is
7509 re-generated in the server. It used to generate the key in
7510 wrong order and thus caused problems in the channel traffic.
7512 * Fixed a minor bug in channel key distsribution after
7513 KICK command. The key was not sent to the router even though
7516 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7518 * Added silc_ske_process_key_material_data as generic routine
7519 to process any key material as the SILC protocol dictates. The
7520 function is used by the actual SKE library but can be used by
7521 applications as well. This relates to the private message keys
7522 and the channel private keys since they must be processed the
7523 same way the normal SILC session keys. The protocol dictates
7524 this. Affected files: lib/silcske/silcske.[ch].
7526 Added also silc_ske_free_key_material to free the
7527 SilcSKEKeyMaterial structure.
7529 * Defined silc_cipher_set_key function to set the key for
7530 cipher without using the object's method function. The affected
7531 files: lib/silccrypt/silccipher.[ch].
7533 * Implemented silc silc_client_add_private_message_key,
7534 silc_client_add_private_message_key_ske,
7535 silc_client_del_private_message_key,
7536 silc_client_list_private_message_keys and
7537 silc_client_free_private_message_keys functions in the
7540 Added functions silc_client_send_private_message_key to send
7541 the Private Message Key payload and silc_client_private_message_key
7542 to handle incoming Private Message Key payload.
7544 * Added Cipher field to the Private Message Key payload to set
7545 the cipher to be used. If ignored, the default cipher defined
7546 in the SILC protocol (aes-256-cbc) is used.
7548 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7550 * Removed lib/silcclient/ops.h file.
7552 Redefined parts of the SILC Client Library API. Created new
7553 file silcapi.h that deprecates the ops.h file and defines the
7554 published Client Library API. Defined also private message key
7555 API and channel private key API into the file.
7557 This is the file that the application must include from the
7558 SILC Client Library. Other files need not be included by
7559 the application anymore.
7561 * Added new key_agreement client operation callback and also
7562 defined the Key Agreement library API for the application.
7564 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7566 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7567 is used by clients to request key negotiation between another
7568 client in the SILC network. If the negotiation is started it
7569 is performed using the SKE protocol. The result of the
7570 negotiation, the secret key material, can be used for example
7571 as private message key.
7573 Implemented the Key Agreement payload into the files
7574 lib/silccore/silauth.[ch].
7576 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7578 * Redefined ciphers for the SILC protocol. Added some new ciphers
7579 and defined the key lengths for the algorithms. Changed the
7580 code accordingly. The default key length is now 256 bits.
7582 * Fixed SKE key distribution function silc_ske_process_key_material
7583 when the key length is more than 128 bits. The default key
7584 length in SILC is now 256 bits.
7586 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7587 to indicate unsupported algorithm.
7589 * Renamed rijndael.c to aes.c and all functions as well.
7591 * Fixed a long standing channel key setting bug in client library.
7592 Weird that it has never surfaced before.
7594 * Fixed bug in channel deletion. If the entire channel is removed
7595 then it must also delete the references of the channel entry
7596 from the client's channel list as the client's channel entry and
7597 the channel's client entry share same memory.
7599 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7601 * Implemented CONNECT and SHUTDOWN commands in the client.
7603 * Implemented CLOSE command to the client.
7605 * Added the function silc_idlist_find_server_by_name into the
7606 files silcd/idlist.[ch].
7608 Added the function silc_idlist_find_server_by_conn into the
7609 files silcd/idlist.[ch].
7611 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7613 * DIE command was renamed to SHUTDOWN. Updated the both code
7616 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7617 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7619 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7622 * Added function silc_server_create_connection function to create
7623 connection to remote router. My server implementation actually
7624 does not allow router to connect to normal server (it expects
7625 that normal server always initiates the connection to the router)
7626 so the CONNECT command is only good for connecting to another
7629 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7631 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7632 or some other client was kicked from the channel.
7634 Implemented the handling of the notify type to both client
7637 Implemented silc_server_send_notify_kicked to send the KICKED
7638 notify. It is used to send it to the server's primary router.
7640 * Implemented the KICK command into server and client.
7642 * Added `query' argument to the silc_idlist_get_client function
7643 to indicate whether to query the client from server or not if
7646 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7647 to indicate that the client is not channel founder.
7651 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7653 * Removed the rng context from SilcPacketContext structure and
7654 changed that the packet routine uses the Global RNG API.
7656 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7658 * Added support for quit message that client can "leave" on the
7659 channel when it quits the SILC. It is ditributed inside the
7660 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7662 Added silc_server_free_client_data that will take the
7663 signoff message as argument.
7665 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7667 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7669 * Updated parts of the protocol specification to keep it up
7672 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7674 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7675 payloads in one packet.
7677 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7678 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7679 use now the new List flag.
7681 * Also deprecated the following packet types: REPLACE_ID,
7682 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7684 * Added list support for Notify packet in server.
7686 * Added silc_server_send_notify_channel_change to send the
7687 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7688 the silc_server_send_replace_id.
7690 * Added silc_server_send_notify_nick_change to send the
7691 NICK_CHANGE notify type. Deprecates the function
7692 silc_server_send_replace_id.
7694 * Added silc_server_send_notify_join to send the JOIN notify type.
7695 Deprecates the function silc_server_send_new_channel_user.
7697 * Added silc_server_send_notify_leave to send LEAVE notify type.
7698 Deprecates the function silc_server_send_remove_channel_user.
7700 * Added silc_server_send_notify_cmode and
7701 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7702 types. Deprecates the silc_server_send_set_mode function.
7704 * Added SERVER_SIGNOFF notify type to indicate that server has
7705 quit. This means that all clients on the channel from that
7706 server will drop. This can be also used when netsplit happens.
7708 Deprecated REMOVE_ID packet type since it is not needed anymore
7711 Added silc_server_send_notify_server_signoff to send the
7712 SERVER_SIGNOFF notify type. Deprecates the function
7713 silc_server_send_remove_id.
7715 Added also silc_server_send_notify_signoff to send the
7716 SIGNOFF notify type.
7718 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7719 SILC protocol from this day on. Changed the protocol
7720 specification as well.
7722 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7723 notify type. It is used between routers to notify about
7724 topic changes on a channel.
7726 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7729 * Partly updated the protocol specification to comply with the
7730 changes now made. It is still though a bit outdated.
7732 * The JOIN notify type now takes one extra argument <Channel ID>.
7733 The packet used to be destined to the channel but now the
7734 JOIN type may be sent as list thus it is impossible to
7735 destine it to any specific channel. By adding this argument
7736 it is again possible.
7738 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7740 * Added CREDITS file. The CHANGES and CREDITS file will appear
7741 in the distribution as well.
7743 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7745 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7746 types in the server's silcd/packet_receive.c.
7748 * Implemented CMODE and CUMODE to work in router environment.
7750 * Fixed minor encoding and decoding buglet from the
7751 lib/silccore/silcmode.c.
7753 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7756 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7758 * Changed all SilcConfigServer* and silc_config_server* to
7759 SilcServerConfig* and silc_server_config*, respectively.
7762 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7764 * Associated the ID (client or server ID) to the Authentication
7765 Payload to avoid any possibility of forging. Updated the
7766 protocol specification and the code accordingly.
7768 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7770 * The RSA key length is now save to the RsaKey context in the
7771 key generation process in lib/silccrypt/rsa.c. The key length
7772 is now used to figure out the maximum size of the block allowed
7773 to be encrypted/signed.
7775 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7776 is equivalent to the silc_mp_mp2bin but does not allocate any
7779 * Changed silc_mp_mp2bin API to take length argument. If it is
7780 non-zero then the buffer is allocated that large. If zero, then
7781 the size is approximated using silc_mp_sizeinbase, which however
7784 * Created Global RNG API which is global RNG that application can
7785 initialize. After initializing, any routine anywhere in the
7786 code (including library) can use RNG without allocating a new
7787 RNG object. This was done to allow this sort of use of the
7788 RNG in code that has no chance to allocate RNG object. All
7789 applications currently allocate this and many routines in the
7790 library use this. Affected file lib/silccrypt/silcrng.[ch].
7792 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7793 it to use the Global RNG API.
7795 * Defined Authentication Payload into protocol specification that
7796 is used during SILC session to authenticate entities. It is
7797 used for example by client to authenticate itself to the server
7798 to obtain server operator privileges.
7800 Implemented this payload into the lib/silccore/silcauth.[ch].
7801 Implemented also routines for public key based authentication
7802 as the new protocol specification dictates.
7804 Moved definitions of different authentication methods from
7805 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7807 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7808 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7809 silc_pkcs_verify_with_hash functions into the file
7810 lib/silccrypt/silcpkcs.[ch].
7812 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7814 * The client entry's userinfo pointer must be always valid.
7815 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7816 will fail since it requires the userinfo. Now, the userinfo
7817 is allocated as "" if actual userinfo does not exist. Actually,
7818 it must exist and it is totally Ok to drop client connections
7819 that does not announce the userinfo. However, we will make
7820 this workaround for now.
7822 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7823 to return the remote port by socket.
7825 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7827 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7828 SILC_SERVER_PENDING_EXEC and added an new macro
7829 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7830 data or when error occurs while processing the pending command.
7832 Added new argument `destructor' into silc_server_command_pending
7833 and to the SilcServerCommandPending object. This destructor is
7834 now called after calling the pending callback or if error occurs
7835 immediately. If error occurs the actual pending callback won't
7836 be called at all - only the destructor. The destructor may be
7837 NULL if destructor is not needed.
7839 All this applies for client library code as well. Similar
7840 changes were made there as well for the pending commands.
7842 In the client, the application must now allocate the
7843 SilcClientCommandContext with the silc_client_command_alloc
7846 * Added reference counter to the SilcServerCommandContext. Added
7847 function silc_server_command_alloc and silc_server_command_dup
7850 Same type of functions added to the client library for the same
7853 * Removed the cmd_ident from IDListData away since it is now
7854 global for all connections. It is the command identifier used
7855 in command sending and with pending commands. The affected file
7858 * Added reference counter to the SilcSocketConnection objecet to
7859 indicate the usage count of the object. The object won't be
7860 freed untill the reference counter hits zero. Currently only
7861 server uses this, and client ignores it. The client must be
7862 set to use this too later. The affected files are
7863 lib/silccore/silcsockconn.[ch]. Added also the function
7864 silc_socket_dup to increase the reference counter.
7866 This was mainly added because it is possible that the socket
7867 is removed underneath of pending command or other async
7868 operation. Now it won't be free'd and proper DISCONNECTING
7869 flags, etc. can be set to avoid sending data to connection that
7870 is not valid anymore.
7872 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7873 the connection. After that it sets SILC_SET_DISCONNECTED.
7874 It is, however, possible that the socket data is not still freed.
7875 The silc_server_packet_process now checks that data is not
7876 read or written to connection that is DISCONNECTED. The socket
7877 get's freed when the reference counter hits zero.
7879 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7881 * Changed the client operation API: channel_message operation's
7882 `sender' is now the client entry of the sender, not the nickname
7883 and the `channel' is the channel entry, not the channel name.
7885 In the private_message operation the `sender' is now also the
7886 client entry of the sender not the nickname.
7888 Affected file is lib/silcclient/ops.h and all applications
7889 using the client operations.
7891 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7893 * Moved the calling of ops->connect() from connect_to_server_final
7894 into receive_new_id functin since that is the point when the
7895 client is actually allowed to send traffic to network. The
7896 affected file is lib/silcclient/client.c.
7898 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7900 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7901 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7902 (if needs broadcasting) instead of broadcasting the packets one
7903 by one which would make a burst in the network traffic.
7905 * Added `broadcast' argument to the functions in silcd/server.[ch]
7906 silc_server_create_new_channel[_with_id] to indicate whether
7907 to send New Channel packet to primary router.
7909 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7911 * Added new function into the silcd/server.[ch] files:
7912 silc_server_create_new_channel_with_id to create new channel with
7913 already existing Channel ID.
7915 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7916 lib/silccore/silcpacket.h. This packet is used t send list of
7917 Set Mode payloads inside one packet. Server uses this to set
7918 the modes for the channels and clients on those channels, that it
7919 announced to the router when it connected to it. The protocol
7920 specification has been updated accordingly.
7922 * The silc_server_new_channel did not handle the packet coming
7923 from normal server as it normally does not send that. However,
7924 when it announces its channels it does send it. Implemented
7925 the support for that.
7927 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7928 into the file lib/silccore/id.h.
7930 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7932 * Fixed memory leaks in the functions silc_idlist_del_client,
7933 silc_idlist_del_channel and silc_idlist_del_server in the file
7934 silcd/idlist.c. All of those leaked like a sieve.
7936 * Fixed some small memory leaks in the client's function
7937 silc_client_notify_by_server.
7939 * Added functions into silcd/server.c: silc_server_announce_clients,
7940 silc_server_announce_channels and silc_server_announce_server.
7941 These functions are used by normal and router server to announce
7942 to its primary router about clients, channels and servers (when
7943 router) that we own. This is done after we've connected to the
7946 These functions effectively implements the following packet types:
7947 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7948 and SILC_PACKET_NEW_ID_LIST.
7950 * Added new functions into the silcd/packet_receive.[ch]:
7951 silc_server_new_id_list, silc_server_new_channel_list and
7952 silc_server_new_channel_user_list to handle the incoming
7953 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7955 * Added support of changing Channel ID in the function
7956 silc_server_replace_id. If the server that announces a channel
7957 to the router already exists in the router (with same name but
7958 with different Channel ID), router is responsible to send
7959 Replace ID packet to the server and force the server to change
7960 the Channel ID to the one router has.
7962 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7963 client that the Channel ID has been changed by the router. The
7964 normal server sends this to the client. Client must start using
7965 the new Channel ID as the channel's ID.
7967 Implemented handling of this new type into lib/silcclient/client.c
7968 into the function silc_client_notify_by_server.
7970 * Added new function silc_idlist_replace_channel_id into the files
7971 silcd/idlist.[ch] to replace the Channel ID.
7973 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7975 * Call silc_server_command_identify_check always when processing
7976 the IDENTIFY command in silcd/command.c
7978 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7980 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7981 send keepalive packets. The packet can be sent by clients,
7982 servers and routers.
7984 Added function silc_socket_set_heartbeat into the file
7985 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7986 If not set, the heartbeat is not performed. The actual
7987 heartbeat is implemented in the low level socket connection
7988 library. However, application is responsible of actually
7991 Added silc_server_send_heartbeat to send the actual heartbeat
7992 packet into silcd/packet_send.[ch]. Server now performs
7993 keepalive with all connections.
7995 * Added silc_task_get_first function into lib/silcutil/silctask.c
7996 to return the timeout task with shortest timeout. There was a bug
7997 in task unregistration that caused problems. TODO has been
7998 updated to include that task system must be rewritten.
8000 * The client library will now resolve the client information when
8001 receiving JOIN notify from server for client that we know but
8002 have incomplete information.
8004 * Rewrote parts of silc_server_remove_from_channels and
8005 silc_server_remove_from_one_channel as they did not remove the
8006 channel in some circumstances even though they should've.
8008 * Encryption problem encountered in server:
8010 The LEAVE command used to send the Channel Key packet to the
8011 router immediately after generating it. However, the code
8012 had earlier sent Remove Channel user packet but not immediately,
8013 ie. it was put to queue. The order of packets in the router
8014 was that Channel Key packet was first and Remove Channel User
8015 packet was second, even though they were encrypted in the
8016 reverse order. For this reason, MAC check failed. Now, this
8017 is fixed by not sending the Channel Key packet immediately but
8018 putting it to queue. However, this is more fundamental problem:
8019 packets that are in queue should actually not be encrypted
8020 because packets that are sent immediately gets encrypted
8021 actually with wrong IV (and thus MAC check fails). So, packets
8022 that are in queue should be encrypted when they are sent to
8023 the wire and not when they put to the queue.
8025 However, the problem is that the current system has not been
8026 designed to work that way. Instead, the packet is encrypted
8027 as soon as possible and left to the queue. The queue is then
8028 just purged into wire. There won't be any fixes for this
8029 any time soon. So, the current semantic for packet sending
8032 o If you send packet to remote host and do not force the send
8033 (the packet will be in queue) then all subsequent packets to the
8034 same remote host must also be put to the queue. Only after the
8035 queue has been purged is it safe again to force the packet
8038 o If you send all packets immediately then it safe to send
8039 any of subsequent packets through the queue, however, after
8040 the first packet is put to queue then any subsequent packets
8041 must also be put to the queue.
8043 Follow these rules and everything works fine.
8045 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8047 * Added new function silc_server_remove_clients_by_server to
8048 remove all client entries from ID list when the server connection
8049 is lost. In this case it is also important to invalidate all
8050 client entires as they hold the invalid server entry. This
8051 fixes fatal bug when server has lost connection and will reconnect
8054 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8056 * Made some sanity checks to silc_server_daemonise like to check
8057 whether the requested user and group actually exists.
8059 * Added sanity check to SKE's silc_ske_responder_finish to check
8060 that the public and private key actually is valid.
8062 * Invalidate the client's nickname when receiving Replace ID
8063 packet and the Client ID is being replaced. This means that the
8064 server will query the nickname if someone needs it (client)
8067 * Sort the ID Cache in client library when the ID Cache data
8068 has changed (needs sorting).
8070 * Do not allow for SILC client to create several connections to
8071 several servers. The client does not support windows right now
8072 and generating multiple connections causes weird behaviour.
8074 Irssi-silc client does support windows and can handle several
8075 connections without problems, see: www.irssi.org and SILC plugin.
8077 * Fixed some places where client was added to the IDList. The
8078 rule of thumb is following (in order to get everything right):
8079 If the client is directly connected local client then the
8080 `connection' argument must be set and `router' argument must be
8081 NULL to silc_idlist_add_client function. If the client is not
8082 directly connected client then the `router' argument must
8083 bet set and the `connection' argument must be NULL to the
8084 silc_idlist_add_client function.
8086 * The funtion silc_server_packet_send_local_channel actually did
8087 not check whether the client was locally connected or not. It
8088 does that now. Fixed a bug related to LEAVE command.
8090 * Fixed Remove Channel User payload parsing bug in server's
8091 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
8093 * The server's silc_server_save_channel_key now checks also the
8094 global ID list for the channel as it might not be in the local
8095 list. Fixed a bug related to LEAVE command.
8097 * Is this the end of the [<unknown>] buglet that has been lurking
8098 around for a long time? A little for loop fix in server's
8099 silc_server_command_whois_parse that is used by both IDENTIFY
8100 and WHOIS command. At least, this was a clear bug and a cause
8101 of one type of [<unknown>] buglet.
8103 * WHOIS and IDENTIFY commands call the function
8104 silc_server_command_[whois/identify]_check function even if
8105 we are not router server.
8107 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8109 * Added --with-gmp configuration option. If set the GMP
8110 is always compiled in the SILC source tree. If not set then
8111 it is checked whether the system has the GMP3 installed. If
8112 it has then the GMP won't be compiled (the system's headers
8113 and library is used), if it doesn't have it then the GMP is
8114 compiled in the SILC source tree.
8116 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8118 * Changed RSA private exponent generation to what PKCS #1
8119 suggests. We try to find the smallest possible d by doing
8120 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
8121 not security fix but optimization.
8123 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8125 * Added new config entry [Identity] to fork the server and run
8126 it as specific user and group. A patch from Bostik.
8128 * Imported Dotconf configuration library into lib/dotconf.
8129 This will be used to create the SILC configuration files later.
8130 It will appear in the distsribution after this commit.
8132 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8134 * A big code auditing weekend happening. Auditing code for
8135 obvious mistakes, bugs and errors. Also, removing any code
8138 Removed files for being obsolete:
8140 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
8141 inline in the file lib/silcutil/silcbuffer.h)
8143 o lib/silcutil/silcbufutil.c (the header has inline versions)
8145 Changed code to fix possible error conditions:
8147 o The buffer formatting routines now check that the destination
8148 buffer really has enough space to add the data. This applies for
8149 both buffer formatting and unformatting
8150 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
8151 unformatting was changed to accomodate following rules:
8152 XXX_*STRING_ALLOC will allocate space for the data into the pointer
8153 sent to the function while XXX_*STRING will not allocate or copy
8154 the data into the buffer. Instead it sets the pointer from the
8155 buffer into the pointer sent as argument (XXX_*STRING used to
8156 require that the pointer must be allocated already). This change
8157 makes this whole thing a bit more consistent and more optimized
8158 (note that the data returned in the unformatting with XXX_*STRING
8159 must not be freed now). The routines return now -1 on error.
8161 o Tried to find all code that use buffer_format and buffer_unformat
8162 and added return value checking to prevent formatting and
8163 especially unformatting errors and possible subsequent fatal
8166 o Changed ske->x and ske->KEY to mallocated pointers in
8167 lib/silcske/silcske.h. Fixed possible data and memory leak.
8169 o Added return value checking to all *_parse* functions. Fixed
8170 many memory leaks as well.
8172 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
8173 so that buffer overflows would not happen. All code now also
8174 checks the return value as it can fail.
8176 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8178 * Added reconnection support to server if the normal server looses
8179 its connection to the router (for example if router is rebooted).
8180 The server performs normal reconnection strategy implemented
8181 to the server. Affected file silcd/server.c.
8183 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8185 * Added new packet type SILC_PACKET_SET_MODE that is used to
8186 distribute the information about changed modes (for clients,
8187 channels and clients channel modes) to all routers in the
8188 network. Updated the protocol specification accordingly.
8190 Added functions into silcd/packet_send.c and
8191 silcd/packet_receive.c: silc_server_send_set_mode,
8192 silc_server_set_mode.
8194 Added new files silcmode.[ch] into lib/silccore that implements
8195 the encoding and decoding of Set Mode Payload. Added new type
8196 SilcSetModePayload. Moved the definitions of different modes
8197 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
8199 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8201 * Oops, a little mistake in server's connection authentication
8202 protocol. The protocol is not ended with FAILURE but with
8203 SUCCESS if the authentication is Ok. :) Affected file is
8206 * Implemented NICK_CHANGE notify handling in server in the file
8207 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
8208 the local clients on the channel. After the changing nickname
8209 in router environment snhould work and the [<unknown>] nickname
8210 should appear no more.
8212 The silc_server_replace_id function that receives the Replace ID
8213 payload now sends the NICK_CHANGE notify type also in the file
8214 silcd/packet_receive.c
8216 * Changed WHOIS and IDENTIFY command to support the maximum amount
8217 of arguments defined in protocol specs (3328 arguments). This
8218 fixed a bug that caused problems when there were more than three
8221 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8223 * Added extra parameter, command identifier, to the
8224 silc_client_send_command so that explicit command identifier
8227 Changed that ID list routines uses specific command identifier
8228 when sending WHOIS/IDENTIFY requests to the server so that they
8229 can be identified when the reply comes back.
8231 Affected files lib/silcclient/command.[ch],
8232 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
8234 * Added `sender' argument to silc_server_packet_send_to_channel
8235 to indicaet the sender who originally sent the packet to us
8236 that we are now re-sending. Ignored if NULL. Affected file
8237 silcd/packet_send.[ch].
8239 * Added some server statistics support in silcd/server_internal.h
8240 SilcServerStatistics structure and around the server code. Also
8241 send some nice statistics information when client is connecting
8244 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8246 * Fixed channel ID decoding in server's JOIN command reply in
8247 silcd/command_reply.c
8249 * Fixed braodcasting of replace ID payload to not to send it if
8250 we are standalone server in silcd/packet_receive.c.
8252 * Fixed all channel message sending routines to not to send
8253 packets to clients that has router set, since they are routed
8254 separately in the same function earlier. Affects file
8255 silcd/packet_send.c and all channel packet sending functions.
8257 * In USERS reply, res_argv[i] are not allocated, the table
8258 is allocated. Thus changed that free the table, not its
8261 * In server's whois_check and identify_check if the client is
8262 locally connected do not send any WHOIS commands - they are not
8265 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8267 * Fixed some minor bugs in client when sending WHOIS command. The
8268 arguments was in wrong order.
8270 * Removed statis function add_to_channel from server in
8271 silcd/command.c that was previously used with the joining but
8274 * Tested USERS command in router environment successfully with two
8275 routers, two servers and two clients.
8277 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8279 * Reorganized the USERS command and command reply in client library
8280 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
8281 When the command is given by user we register a pending command
8282 callback that will reprocess the command after the reply has been
8283 received from the server. When reprocessing the packet we then
8284 display the information. Thus, the USERS information is displayed
8285 now in the command callback instead of in the command reply
8286 callback. The processing of the command is same as previously
8287 when server has sent the command reply in the JOINing process.
8289 * Added to USERS command in silcd/command_reply.c to join the client,
8290 we didn't use to know about, to the channel after we've created
8291 a client entry for it. Also, for clienet we did know already still
8292 check whether it is on the channel or not and add it if not.
8294 * Removed silc_server_command_join_notify as the function and its
8297 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8299 * Changed the client's pending command handling to the same as the
8300 server's pending command handling. It is also now possible to
8301 execute command reply functions from other command reply
8302 function as the function callbacks for commands and command
8303 replies are one and same. The pending commands are not static
8304 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8305 in client connection context. Thus, pending commands are server
8306 connection specific as it is convenient.
8308 Changed the function silc_client_command_pending and
8309 silc_client_command_pending_del and added new function
8310 silc_client_command_pending_check. Removed the
8311 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8314 * Added cmd_ident, current command identifier, to the client
8315 connection context in lib/silcclient/client.h to keep track on
8316 command identifiers used in command sending. Client's command reply
8317 function handling now supports the mandatory command identifiers.
8319 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8320 funtions in client to fully support pending command callbacks.
8322 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8323 as one of the arguments to the application in the command reply
8326 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8327 before first releasing SILC but came back. Now it is removed again
8328 and should come back nomore. The FORWARDED flag was used only
8329 by the JOINing procedure by forwarding the command packet to router.
8330 Now, the JOINing procedure has been changed to more generic (due
8331 to various router environment issues) and FORWARDED is not needed
8332 anymore for anything. The protocol specification is yet to be
8335 Now, removed silc_server_packet_forward from server and the flag
8336 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8338 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8340 * Renamed NAMES command to USERS command. The NAMES was named that
8341 due to historical reasons. Now it is renamed. Also, rewrote
8342 parts of the USERS command. The nickname list is not sent anymore
8343 by the server. Only Client ID and mode lists are sent in the USERS
8344 command. Changed this also to the protocol specification.
8346 The client now resolves the names and stuff after it receives
8347 the USERS list from the server when joining to the channel.
8349 * WHOIS and IDENTIFY commands has been changed to support multiple
8350 Client ID's per command. One can now search for multiple users
8351 in the network by sending only one WHOIS or IDENTIFY command.
8352 Changed the code and the protocol specifications.
8354 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8355 uses silc_server_command_whois_parse to parse the request. */
8357 * If normal server, do not parse the WHOIS and IDENTIFY requests
8358 before sending it to the router. Saves some time.
8360 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8362 * Fixed JOIN command on client library. Wrong number of arguments
8363 used to crash the client.
8365 * Added silc_server_channel_has_global function to check whether
8366 channel has global users or not.
8368 * Added silc_server_channel_has_local function to check whether channel
8369 has locally connected clients on the channel.
8371 * The silc_server_remove_from_one_channel now checks whether the
8372 channel has global users or not after given client was removed from
8373 the channel. It also checks whether the channel has local clients
8374 on the channel anymore. If it does not have then the channel entry
8375 is removed as it is not needed anymore.
8377 * The silc_server_notify now checks on JOIN notify whether the joining
8378 client is one of locally connected or global. If it is global then
8379 the channel has now global users on the channel and that is marked
8380 to the channel entry. Also, it now saves the global client to
8381 global list who is joining and JOINs it to the channel. This is
8382 for normal server, that is.
8384 Changed silc_server_send_notify_on_channel,
8385 silc_server_packet_relay_to_channel and
8386 silc_server_packet_send_to_channel check if we are normal server
8387 and client has router set (ie. global client) do not send the
8388 message to that client, as it is already routed to our router.
8390 * Implemented LEAVE notify type handling in silc_server_notify
8393 * Tested LEAVE command in router environment successfully. Tested
8394 with two routers, two servers and two clients.
8398 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8400 * Implemented SIGNOFF notify type handling in silc_server_notify
8403 * silc_server_remove_id now removes the client entry from all channels
8404 it has joined and thusly sends SIGNOFF notify type.
8406 * Rewrote the NAMES list generation in server by removing two excess
8407 loops. The lists are created now inside one loop.
8409 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8411 * silc_server_remove_channel_user checks now also global list
8412 for channel and client.
8414 * silc_server_new_channel_user checks now both local and global
8415 list for channel and client. Fixed a bug in client id decoding.
8416 Used to decode wrong buffer.
8418 * silc_server_channel_message checks now both local and global
8419 list for channel entry.
8421 * Tested channel joining (hence JOIN) in router environment
8422 successfully. Tested with two routers, two servers and two
8425 * Tested channel message sending in router environment successfully.
8427 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8429 * Added silc_server_save_channel_key into server.[ch] to save the
8430 received channel key in Channel Key payload processing. It is
8431 also used in JOIN command reply handling.
8433 Equivalent function silc_client_save_channel_key added into
8434 client.[ch] into client library.
8436 * Changed JOIN command reply to send information whether the channel
8437 was created or not (is existing already) and the channel key
8438 payload. Changed protocol specs accordingly.
8440 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8441 the request was sent by ID and not by nickname. Crashed on
8444 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8446 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8447 now correctly save the received data.
8449 * silc_server_free_sock_user_data now notifies routers in the
8450 network about entities leaving the network.
8452 At the same time implemented functions silc_server_remove_id
8453 and silc_server_send_remove_id to receive and send REMOVE_ID
8454 packets. The packet is used to notify routers in the network
8455 about leaving entities. The ID removed will become invalid in
8458 * Added function silc_idlist_del_server into server. Removes and
8459 free's server entry from ID list.
8461 * silc_server_private_message function now checks, if we are router,
8462 that the destination ID really is valid ID, naturally.
8464 * In router when NEW_ID packet is received (for new client) the
8465 hash of the Client ID is saved in the ID Cache but the
8466 client->nickname is set to NULL, instead of putting the hash
8469 IDENTIFY command now also checks that client->nickname must be
8470 valid. If it is not if will request the data from the server who
8471 owns the client. Added new function
8472 silc_server_command_identify_check.
8474 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8475 to set the command to already allocated Command Payload.
8477 * Tested private message sending in router environment with two
8478 routers, two servers and two clients. Fixed minor bugs and now
8481 * Fixed segfault from client's NAMES command. Used to crash if
8484 * Forwarded packets must not be routed even if it is not destined
8485 to the receiver. Changed server code comply with this.
8487 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8489 * Added `require_reverse_mapping' boolean value to ServerParams
8490 structure. If TRUE (not default) the server will require that
8491 the connecting host has fully qualified domain name.
8493 If the reverse mapping is not required and hostname could not be
8494 found the IP address is used as hostname.
8496 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8498 * Implemented version string checking to both client and server.
8499 The check is incomplete currently due to the abnormal version
8500 strings used in development version of SILC.
8502 * Changed all command functions in server to use the new
8505 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8507 * Changed char *data to unsigned char *data in ID Cache system to
8508 support binary data as ID Cache data. Changed code to support
8509 binary data in lib/silccore/idcache.c.
8511 * Renamed silc_server_packet_relay_command_reply to
8512 silc_server_command_reply as it is normal packet receiving
8513 function. Rewrote the function to accept command replys for
8514 servers and not only for clients.
8516 * Mark remote router always as registered server if we are connecting
8517 to it. Otherwise, commands sent by the router to us are ignored.
8519 * All ID List find routines now returns the ID Cache Entry pointer
8520 as well if requested.
8522 * WHOIS command works now in router environment, tested with two
8523 routers, two servers and two clients.
8525 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8526 in router environment (as it is almost equivalent to WHOIS) but
8527 hasn't been tested thoroughly. Added new functions:
8529 silc_server_command_identify_parse
8530 silc_server_command_identify_send_reply
8531 silc_server_command_identify_from_client
8532 silc_server_command_identify_from_server
8534 * Disabled route cache adding because adding two different ID's with
8535 same IP replaces the old cache entry thus giving wrong route.
8536 The entry->router->connection is always the fastest route anyway
8537 so route cache may not be needed. Of course, new routes maybe
8538 established after receiving the ID when the entry->router->connection
8539 might not be anymore the most optimal.
8541 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8543 * Add route cache for received ID for fast routing.
8545 * Added silc_server_packet_route to route received packet on router
8546 that is not destined to us.
8548 * Renamed silc_server_get_route to silc_server_route_get.
8550 * Added id_string and id_string_len fields into SilcServer to
8551 include encoded ServerID for fast comparing without excess
8552 encoding of the ID's.
8554 * Cleaned up WHOIS command on server side. Added following static
8557 silc_server_command_whois_parse
8558 silc_server_command_whois_check
8559 silc_server_command_whois_send_reply
8560 silc_server_command_whois_from_client
8561 silc_server_command_whois_from_server
8563 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8564 arguments in command replies. All command functions should be
8565 updated to use this macro.
8567 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8569 * Minor typo fixes on command reply handling on server.
8571 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8573 * Added silc_server_command_add_to_channel internal routine to add
8574 the client to the channel after router has created the channel and
8575 sent command reply to the server.
8577 * Added generic silc_server_send_command to send any command from
8580 * Use static buffer with ID rendering instead of duplicating data.
8582 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8584 * Fixed a channel user mode bug when joining to a channel server gave
8585 everybody channel founder rights, oops.
8587 * We mark ourselves as the router of the incoming server connection
8588 if we are router ourselves. This way we can check in some packet
8589 sending functions whether it is locally connected server. For
8590 incoming router connections we put NULL.
8592 * For router sending packets locally means now always sending the
8593 packet cell wide; to local clients and local servers. For normal
8594 server sending packet locally means sending it to only local
8597 * Fixed the JOIN command to really work in router environment. If the
8598 channel is created it is always created by the router. Router is
8599 also responsible of making the initial joining to the channel,
8600 sending JOIN notify to the sending server and distributing
8601 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8602 does not exist server doesn't do anything else but forward the
8603 command to the router which performs everything.
8605 * Added silc_server_send_channel_key function to send the Channel Key
8608 * Added silc_server_create_channel_key to create new channel key. The
8609 channel key is now re-generated everytime someone joins or leaves
8610 a channel, as protocol dictates. Note: channel->key_len is the
8613 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8615 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8616 packet_receive.[ch] to separate packet sending and receiving
8617 routines. The server.[ch] now includes everything else including
8618 actual packet processing (writing and reading data) and other
8621 Renamed silc_server_private_message_send_internal to
8622 silc_server_send_private_message. The routine is still though
8623 used only to relay private messages as server does not send
8624 private messages itself.
8626 Renamed silc_server_new_channel to silc_server_create_new_channel
8627 and added new function sicl_server_new_channel that handles the
8628 incoming New Channel packet. Added also new sending function
8629 silc_server_send_new_channel to send New Channel Payload.
8631 * Added new function silc_server_notify to process incoming notify
8632 packet to the server/router. Server may then relay the notify
8633 to clients if needed.
8635 * Added new function silc_server_new_channel_user to process incoming
8636 New Channel User packet. Router will redistribute the packet and
8637 send JOIN notify to its local clients and locally connected servers
8638 if needed. Normal server will send JOIN notify to its local client
8639 on same channel when received this packet. Added also corresponding
8640 sending function silc_server_send_new_channel_user to sent the
8643 * Added boolean route argument to send_notif_to_channel and
8644 packet_send_to_channel functions to attempt to route the packet
8645 if it is TRUE and send only locally if it is FALSE.
8647 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8649 * silc_server_replace_id now broadcasts the received replace ID
8650 packet if it is not broadcast packet already. The router must
8651 broadcast to inform other routers about changed ID.
8653 * Added backpointer to server's router into SilcServer context in
8654 silcd/server_internal.h.
8656 * Fixed silc_server_packet_broadcast to send correct broadcast
8659 * The channel key is now distributed to the local client as soon
8660 as it is received from the router (in router environment) so that
8661 no other packet may be sent for the channel until client has
8664 * silc_server_remove_channel_user now broadcasts the received
8665 Remove Channel User packet if it is not broadcast packet already.
8666 The router must broadcast to inform other routers about removed
8669 * Added users field into SilcPacketContext that is a reference count
8670 of the context. One can increase the reference count by calling
8671 silc_packet_context_dup which is now changed to just increase the
8672 reference count instead of duplicating the data. The reference
8673 count is decresed by calling silc_packet_context_free that will
8674 free the data after the reference count hits zero.
8676 For now on the packet context and everything allocated into it
8677 (including the raw packet from network) must be freed by calling
8678 the new silc_packet_context_free function. Added also new function
8679 silc_packet_context_alloc that must be used now to allocate the
8680 context. This also means that if a routine is asynchronous from
8681 silc_[client/server]_packet_parse_type the packet context must
8682 be duplicated by calling silc_packet_context_dup. Otherwise it
8683 gets free'd after silc_[client/server]_packet_parse_type returns.
8684 Also, one must remember that if packet is duplicated then its
8685 reference count must be decresed by calling the free function as
8686 many times as it was duplicated.
8688 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8689 from both client and server.
8691 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8693 * Made joining to a channel working in router environment.
8695 * Cleaned up JOIN command on server side and create function
8696 silc_server_command_join_channel internal routine to make the
8699 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8701 * Changed silc_command_pending list to SilcDList. Also, added
8702 `ident' field to SilcServerCommandPending structure to identify
8703 the reply and to call correct callback.
8705 Added silc_server_command_pending_check function to replace the
8706 corresnponding macro. The silc_command_pending list is not
8709 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8710 to set identifier to previously allocated Command Payload. It
8711 is used to set identifier for command when resending Command
8714 * Added silc_command_payload_encode_payload to encode Command
8715 Payload buffer from SilcCommandPayload structure.
8717 * Added silc_argument_payload_encode_payload to encode Argument
8718 payload buffer from SilcArgumentPayload structure.
8720 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8722 * Changed WHOIS command to support router connection on server side.
8723 The whois request is always sent to router unless the server is
8724 standalone server. After server has received the reply from the
8725 router will it send the reply to the client.
8727 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8728 broadcast received broadcast packet. The function is used only
8729 by router. The broadcast packet is always sent to the router's
8732 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8733 render given ID to printable string, for log files for example.
8735 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8737 * Made basic router to router connections working. At least they
8738 can now connect to each other but nothing really works the way
8739 they are supposed - yet.
8741 * Added new initiator token to RouterConnection configuration
8742 file in silcd/serverconfig.[ch]. It is used to tell whether we
8743 are the initiator to the remote router or whether we'll expect
8744 the other end to connect.
8746 * Moved registering of listener task to silc_server_init, hence
8747 the server starts listenning as soon as it is run, even if it
8748 does not have connections to other routers. Let's see how well
8751 * Changed default connection retry timeouts for more suitable in
8754 * Removed cipher and such arguments from silc_idlist_add_client
8755 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8756 Added new function silc_idlist_add_data to add the keys and stuff
8759 * Added SilcIDListData structure and added it to SilcClientEntry
8760 and SilcServerEntry as their first field in the structure. This
8761 way we can explicitly cast the ID entries to the SilcIDListData
8762 structure and get common data for the entries. In past, we had
8763 to first check what type of connection it is and then cast it to
8764 correct ID entry type. Now, we can directly cast the opaque
8765 pointer to the SilcIDListData (no matter what ID entry it actually
8766 is) and get the data needed.
8768 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8770 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8771 in some circumstances even if threre were timeout tasks, though not
8772 IO tasks, but tasks anyway. Now fixed.
8774 * Defined SilcServerConnection structure to hold connection specific
8775 stuff about directly connected servers and routers. The definition
8776 is currently in silcd/server_internal.h. I thought about having
8777 a bit more important role fro this struct but for now it is used
8778 only when connecting to other server (or router actually).
8780 * Added connecting retry support in server when connecting to
8781 router(s). The retry feature implement exponential backoff
8782 algorithm. Also, added SilcServerParams structure to hold default
8783 parameters for server. For now, it include these retry settings
8784 and are hard coded. After server is moded to be as Silc Server
8785 Library this structure will be more important.
8787 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8789 * Changed client librarys channel->clients table to SilcList and
8790 changed code accordingly.
8792 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8794 * Changed client's channel table to SilcList and changed code
8795 accordingly. Also changed SilcChannelClientEntry to include back-
8796 pointer to the channel so that client entry can use that structure
8797 as list as well and we have fast cross-reference to the channel.
8798 This change dramatically decreased the complexity of channel
8799 handling with client entry and vice versa (removed one extra
8800 loop when searching for channel entry from many functions).
8802 * Changed server->sim from table to SilcDList and changed code
8805 * NAMES command can now be used from user interface. It will show
8806 the user list on the channel, neatly.
8808 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8809 Code now saves realname of the user if it becomes available.
8811 * Renamed configure.in to configure.in.pre and made ./prepare
8812 script to automatically add correct version string to
8813 configure.in which it creates from configure.in.pre.
8815 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8817 * NAMES command reply now shows users mode with the nickname when
8820 * Moved silc_client_ch[u]mode[_char] functions from
8821 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8822 place sucks, they are utility functions and should be in some
8825 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8827 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8830 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8834 * Added TRQ (efficient deque and list library) into lib/trq. This is
8835 a very good list library that is currently used in the SILC. Defined
8836 SilcList API over the library because I didn't like the API very
8837 much. See lib/trq/silclist.h for the API and examples of how to
8838 use the API. Fixed various places in the code to use the new
8839 SilcList API. The SilcList is meant for lists that has a structure
8840 already defined as a list. It is not suitable to add just some
8841 context to the list (in TRQ, the context is the list actually).
8843 So, I defined SilcDList that can be used for the purpose where
8844 predefined list structure does not exit. This can be used as
8845 such list. Now some context just can be added to the SilcDList.
8846 Currently this list is not used in the SILC just yet, though there
8847 are a lot places where this can replace dynamically allocated
8848 tables and I will fix these places, later, to use SilcDList.
8849 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8850 and use TRQ internally).
8852 Also fixed some annoying warning messages that the original TRQ
8853 code generated. Also minor changes to TRQ's Makefile.in.
8855 * Added support for querying by Client ID to both WHOIS and
8856 IDENTIFY commands into server, as required by the protocol.
8858 * Removed method function pointers from SilcBuffer structure. They
8859 weren't used to anything and just increased the context size for
8860 no good reason. This change also made silc_buffer_alloc and
8861 silc_buffer_free functions inline functions.
8863 * Disabled command flooding detection support until it's fixed so
8864 that it accepts commands in but does not execute them more than once
8867 * Added silc_net_localhost(), to return local hostname, into
8868 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8869 that must be initialized before calling silc_client_init.
8871 * Added new function: silc_server_send_notify_on_channels to send
8872 notify messages to all channels client has joined. It is assured
8873 that the message is sent only once per client.
8875 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8876 lib/silcutil/silcutil.[ch] as silc_format function. The new
8877 function is generic and is used by server as well, not only by
8878 the logging routines.
8880 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8881 the provided version string was not acceptable. Added new function:
8882 silc_ske_check_version into lib/silcske/silcske.h. The function
8883 must be implemented by the application (client or server) and it
8884 does not reside in the SKE library. The function checks the version
8885 string remote end sent.
8887 * Added back pointers (to opaque context and to SilcSocketConnection)
8888 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8890 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8891 duplicate packet context structure.
8893 * Changed `notify' client operation to send same arguments as client
8894 receives from server except for ID's. ID's are mapped to correct
8895 ID entry and that is returned. Also, if channel entry is not sent
8896 by server but the notify is for channel the channel entry is sent
8897 to application (otherwise application doesn't know that it is for
8898 channel (library gets it from packet's Destination ID)).
8900 * Added silc_client_remove_from_channels into client library to
8901 remove a client from all channels it has joined to. Used when
8902 received SIGNOFF notify from server. Added also new function
8903 silc_client_replace_from_channels to replace old ID entry with
8904 new ID entry on all channels. Used when received NICK_CHANGE
8907 * Fixed ID Cache list handling in silc_idlist_get_client in
8908 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8909 to get (or query) client by ID.
8911 * Updated TODO list.
8913 * Added connection authentication status message defined by the
8914 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8915 support for these into the code in client and server side.
8917 * Added generic function silc_client_send_command to send any command
8918 with variable argument list. Application should use this function
8919 to send commands if the command functions provided by the library
8920 does not suite for the application's user interface needs.
8922 * Added new `failure' client operation. Application is notified about
8923 received failure packet if client is executing a protocol. In this
8924 case the protocol's execution has failed.
8926 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8927 is required by the protocol.
8929 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8930 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8933 * Added status flag to SilcSKE object to indicate realtime status
8934 of the SKE protocol.
8936 * Application receives now exactly same command reply arguments as
8937 the library receives from server. However, if ID is received the
8938 corresponding ID entry is returned to the application (eg. Client
8939 ID is mapped to correct SilcClientEntry entry and that is returned).
8940 Changed command_reply client operation due to this change.
8942 * Changed all ID's in commands and in command replys as ID Payloads.
8943 Change affected both client and server side codes.
8945 All ID's sent in SILC network (with execption of ID's in SILC
8946 Packet header) are sent in ID Payload to support variable length
8949 * Server now notifies nick changes and notifies all clients on
8950 the channels about the new nickname (about the new Client ID,
8953 * Implemented CMODE command to change channel modes. Supports all
8954 channel modes defined by the protocol specs except ban and invite
8955 lists. (Also, private channel key mode is supported but support for
8956 setting private channel key in client is missing, thus, this mode
8957 has no effect on client side (except that server requires that the
8958 client uses private channel key and normal channel traffic does not
8961 Also, invite mode works per se, but INVITE command does not work
8962 yet correctly, so you can set channel as invite only channel but
8963 inviting clients to the channel does not work (it is yet to be
8964 thought what's the best way to do it).
8966 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8967 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8968 Implemented CUMODE command to change user's mode on the channel.
8969 Supports all modes defined by the protocol specs.
8971 * Added NAMES command reply to return users modes on the channel.
8973 * Removed unnecessary and slow ciphers from lib/silccrypt.
8975 * Set SO_KEEPALIVE option to connection sockets by default.
8977 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8979 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8980 redefined the Notify Payload into protocol specs.
8982 * Added silc_id_payload_parse_id to get ID directly from raw
8985 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8987 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8988 accept searching by Client ID as well.
8990 * Added support for LEAVE and SIGNOFF notify types in client library.
8992 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8993 to parse ID Payload from raw data.
8995 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8997 * Added flags parameter into silc_ske_assemble_security_properties
8998 function in lib/silcske/silcske.[ch].
9000 * Changed notify client operation to fit better for notify messages
9001 sent by server. The notify payload received from server is now
9002 passed to the application (after parsing it to SilcNotifyPayload).
9003 It is application's responsibility to retrieve the arguments
9004 from the payload and show the message the way it wants. The message
9005 sent by server is implementation specific.
9007 * Changed public keys to comply with the protocol specification.
9008 Old public keys are not supported anymore and are not compatible.
9010 * Removed nickname from Channel Payload as the latest draft removed
9011 it. The client must resolve the nickname from the NAMES command
9012 reply received when it joined the channel.
9014 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
9016 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9018 * Fixed some errors in protocol specification drafts.
9020 * Created lib/silccore/silcnotify.c to implement Notify Payload
9021 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
9022 generic payloads described by protocol specifications. The file
9023 includes implementations for ID Payload and Argument Payload.
9025 * Changed Command Payload implementation to use the new Argument
9026 Payload. Changed command_xxxx_payload to command_payload_xxxx
9027 to comply with SILC coding conventions.
9029 * Added suppport for Argument Payload handling in Notify Payload
9030 implementation as protocol requires it. Added the new support
9031 into server and client lib as well.
9033 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9035 * Added support for multiple nicknames on same channel. [n] is
9036 added locally to the nickname if there are more than one same
9037 nicknames on the channel.
9039 * Server now sends all nicknames that matched WHOIS request.
9040 Client also shows the list received from server.
9042 * Added TOPIC command to client side. User can now set and show
9043 current topic on channel.
9045 * Added MOTD command to client and server. Also, server sends the
9046 motd when client connects to the server.
9048 * Changed version strings to comply ISO 8601.
9050 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9052 * Fixed protocol error handling in client library. It should now
9053 cope even if the SKE fails for some reason.
9055 * Made new protocol specification drafts for submitting to IETF.
9057 * Implemented TOPIC command to server in silcd/command.c.
9059 * Added two new notify types into lib/silccore/silcnotify.h:
9060 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
9061 notify nickname change and topic setting/change on a channel.
9063 * API change of command_reply operation in client library. The
9064 application gets now the status type received from server as well.
9066 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9068 * Removed the function just added to lib/silcutil/silcschedule.[ch].
9070 * Cras fixed and optimized the packet handling even further and
9071 it should work now. Minor change to the prototype of function
9072 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
9074 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9076 * Added new function into lib/silcutil/silcschedule.[ch]:
9077 silc_schedule_with_fd to select() a specified fd. The function
9078 returns after timeout expires or data arrives or goes. The
9079 function is used by packet routines to wait that all data is
9080 received from network.
9082 * Fixed data reading from network in lib/silccore/silcpacket.c.
9083 The code now assures that all data is read from the fd and then
9084 continues packet processing. This was a bug fix since the code
9085 used to drop some data in some circumstances.
9087 * Added new function into lib/silcclient/client.[ch]:
9088 silc_client_start_key_exchange to start key exchange after
9089 connection has been established to server. The code internally
9090 now uses this funtion but its main purpose was to provide it
9091 for applications that perform their own connecting. After
9092 application has created a connection it merely calls this
9093 function to start the key exchange between client and server.
9094 The library takes care of everything else after that.
9096 Updated also lib/silcclient/README to explain the usage of
9099 * Do not send to application information that connection has
9100 been established. Application gets notified it by connect
9103 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9105 * Applied cras's patch to add silc_schedule_one function. The
9106 function runs scheduler once and returns.
9108 * Fixed the scheduler after cras messed it up. The timeout
9109 handling works now as it's supposed to work.
9111 * Added into lib/silccore/ silcnotify.h to include notify
9112 message types support. Changed silc_server_send_notify*
9113 functions, in server.[ch], to support those new notify types.
9114 Added the support for the notify types into client library,
9115 as well. Added new notify client operation into ops.h in
9118 * Changed silc_server_packet_send_to_channel to send normal
9119 packets instead of just channel message packets. The function
9120 is now used to send the notify packets to channels. It is not
9121 used to send channel message packets anymore, as server never
9124 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
9125 va_arg()s as it seems to require it nowadays. I guess, if SILC
9126 is compiled with older va_arg() the new code should work anyway.
9128 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9130 * Splitted core library. Core library (lib/silccore) includes
9131 now only SILC protocol specific core (and common) components.
9132 Created new utility library (lib/silcutil) that includes more
9133 generic purpose stuff. The stuff for util library was taken
9134 from the old core library. This was minor and easy split.
9136 * Created SILC Client Library (lib/silcclient) that includes
9137 implementation of the SILC client without user interface. This
9138 was major move from silc/ directory. The code has been changed
9139 so that it is transparent towards the user interface. The
9140 silc/ directory includes now the same user interface as before
9141 and it uses the new client library. Read lib/silcclient/README.
9142 Basicly, the client library performs everything else related
9143 to SILC except user interface handling. Also, configuration
9144 files are considered to be part of user interface and library
9145 does not handle them.
9147 This change also changed a lot of structures, function naming etc.
9148 Most important change was that SilcClientWindow object was
9149 renamed to SilcClientConnection in the client library. Created
9150 also new file lib/silcclient/ops.h. Also added new files
9151 silc/local_command.[ch] and silc/client_ops.[ch].
9153 All these changes were made to make it easier for user interface
9154 designers to create what ever user interface for the SILC client
9157 It is also expected that the server will be moved to lib
9158 directory as well and SILC Server Library will be created;
9159 sometimes in the future.
9161 * Removed Local commands from lib/silccore/silccommand.h as
9162 they are application specific and new client library does not
9163 handle any of those anymore.
9165 * Several functions moved to lib/silcutil/silcutilc.[ch] from
9166 old client implementation in silc/.
9168 * Added support for callback functions in SILC_LOG_* macros.
9169 Application can now set its own callbacks that will be called
9170 instead of using the default functions that will always print
9171 the debug messages to stderr (or stdout). Also, debugging can
9172 now be disabled by setting silc_debug to FALSE and re-enabled by
9173 setting it to TRUE. Note, that logging will still work even
9174 if debugging is disabled.
9176 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
9177 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
9178 silc_log_reset_debug_callbacks.
9180 * To enable debugging in silc client one must give now -d
9181 option on command line.
9183 * Changed silc_schedule_init to automatically allocate task queues
9184 if they are not allocated before calling it.
9186 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9188 * Added GMP 3.1 into math library.
9190 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9192 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
9193 a channel in SILC network. The packet is used by servers and
9194 routers to notify other routers that user has left a channel.
9195 This little feature was missing until now. Added the feature
9196 to protocol specification as well.
9198 Added functions: silc_server_send_remove_channel_user and
9199 silc_server_remove_channel_user into server.[ch].
9201 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
9202 lib/silccore/silcpacket.h. However, they are not implemented
9205 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9207 * Fixed joining to a channel and sending channel messages
9208 between server and router. The channel message sending should
9209 now work inside a cell.
9211 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9213 * Fixed the private message sending between server and router.
9214 The private message sending should now work inside a cell.
9216 * Added silc_server_replace_id into server.[ch] to replace
9217 existing ID in the SILC network.
9219 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
9220 and silc_idlist_replace_server_id into idlist.[ch] in server.
9222 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9224 * Fixed the server to server connections. Server can again now
9225 connect to router. Router to router connections probably does
9228 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9230 * Added dynamic protocol registering support. Now protocols can
9231 registered and unregistered on the fly. Patch by cras.
9233 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9235 * Added lib/contrib directory to hold routines that some platforms
9236 don't have but are needed by SILC.
9238 * Added getopt.c, getopt1.c and getopt.h from GNU C library
9239 into lin/contrib to provide getopt() and getopt_long() for
9240 those who don't have it.
9242 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9244 * Added AWAY command to client. When away message is set and
9245 client receives a private message packet the client automatically
9246 replies to the sender with the away message.
9248 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
9249 bug seemed to be the cause of recent problems when compiling
9252 * Added version detection support to SKE protocol specification
9253 and added the new changes to the SKE implementation as well.
9254 There were other minor changes in the SKE protocol as well.
9256 Many changes in lib/silcske/silcske.[ch] and in
9257 lib/silcske/payload.[ch].
9259 * Added ^U functionality, clear input line. Patch from cras.
9261 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9263 * Mainly small bugfixes on core library. Fixed some debugging
9264 logging and buffer overflow in silclog.c.
9266 * Updated config.sub and config.guess on the distribution tree.
9268 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9270 * Added command lagging support in server. Client may execute
9271 commands now only once in two seconds.
9273 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9275 * Optimized packet reception. MAC computation and checking is now
9276 also more optimized. A lot previously duplicated code is now
9277 used as generic by both client and server.
9279 * Fixed key pair generation in clientutil.c
9281 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9283 * Added into lib/silccore/silcbufutil.[ch] new function;
9284 silc_buffer_realloc.
9286 * Moved generic packet sending/encryption functions to
9287 lib/silccore/silcpacket.[ch] from client and server. Some
9288 rewriting of the functions.
9290 * Moved all generic packet reception/decryption functions to
9291 lib/silccore/silcpacket.[ch] from client and server. The
9292 packet processing is now much cleaner in both client and server.
9293 These were major changes in both client and server.
9295 * Created many common functions in server to do packet sending.
9296 Previously code were duplicated a lot, this has been removed
9299 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9301 * Rewrote major parts of the ID cache system. Don't know
9302 whether it is better now or not but at least the API is more
9305 * Major rewrite on ID cache stuff on client because of the ID
9306 cache API changes. Added idlist.c to client.
9308 * Also major rewrite on ID cache stuff on server as well.
9309 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9310 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9311 in hand, instead they are all put into the ID cache system now.
9312 All server_idlist_* routines uses ID cache now instead of
9313 traversing its own lists (those lists does not exist anymore).
9314 SilcIDList though still exists. Also, SilcXXXEntry's are
9317 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9319 * Finally made the SKE implementation compliant to the protocol
9320 specification. All mp integers are now binary encoded as
9321 opposed being HEX encoded.
9323 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9326 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9327 functions: silc_[encode/decode]_pem. Also added function
9328 silc_encode_pem_file to PEM encode with newlines ('\n') for
9331 * SILC public keys are now encoded either PEM or binary. Same
9332 option is for private keys as well. By default private keys
9333 are binary encoded and public keys PEM encoded. Silly HEX
9334 encoding were removed.
9336 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9337 function to create fingerprints.
9339 * Fixed a bug in SHA1; does not change the original data anymore.
9341 * Partly implemented INFO command on client and server side.
9342 Fixed CLEAR command. Changes to SERVER command; show current
9343 server(s) when giving command without arguments. Added
9344 VERSION command to client.
9346 * Added check to server that unregistered connections cannot
9347 execute commands (unless it is specificly allowed).
9349 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9351 * Fixed screen refresh.
9353 * Fixed channel joining bug from client. On some circumstances
9354 client tried to join to a channel it had already joined.
9356 * Added public key verification process into client's protocol.c.
9357 The client now verifies the public key from user and saves
9358 it into ~./silc/serverkeys/ directory.
9360 Added into: clientutil.[ch]: silc_client_verify_server_key.
9362 * Changed SKE protocol's silc_ske_initiator_finish function
9363 to accept callback function that verifies the received public
9364 key. Removed old silc_ske_verify_public_key function.
9366 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9368 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9369 silc_pkcs_private_key[_data]_set.
9371 * Made the password and public authentication more cleaner in
9372 server's protocol.c.
9374 * Removed historic and obsolete protocol `channel_auth' from
9375 both client and server.
9377 * Removed wrong way of sending command status messages from
9378 server to client in server's command.c. The old way violated
9379 protocol specification.
9381 Changes to silccore/silccommand.[ch]: removed
9382 silc_command_encode_status_payload -> not needed anymore,
9383 changed silc_command_encode_payload_va to accept extra
9384 argument on variable argument list. The argument type must
9385 now be provided to the function. Also, added new function:
9386 silc_command_encode_reply_payload_va which is same as
9387 normal command_encode_payload_va except command status type
9388 is provided as extra argument.
9390 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9392 * Added ~./silc directory handling. The directory includes the
9393 public and private keys for the client.
9395 Added silc_client_check_silc_dir, silc_client_create_identifier
9396 and silc_client_load_keys.
9398 * Implemented SILC protocol compliant public key. Added public
9399 and private key saving to and loading from files.
9401 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9402 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9403 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9404 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9405 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9407 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9408 silc_pkcs_load_[public/private]_key.
9410 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9412 * Added silc_server_get_route (route.[ch]) to get connection
9413 data for the fastest route for given ID.
9415 * Implemented INVITE command on client and server. The command
9416 were re-defined in the SILC Protocol Specification and the
9417 implementation now complies with the specification.
9419 * Implemented PING command on client and server.
9421 * Implemented NAMES command on client and server. The server side
9422 supports currently only normal server not router server yet.
9423 Some changes to NAMES definition in SILC protocol specification.
9425 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9427 * Implemented LEAVE command on client and server.
9429 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9430 again. This change was made to the protocol as well. Server
9431 should not violate the protocol specification anymore.
9433 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9435 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9436 was tested. SOCKS4 was not but should work anyway.
