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

130 the Requested Attributes from the client. Fixed memory leak
131 in client entry freeing. Affected files silcd/server_query.c
134 * Added Requested Attributes support into SILC Client Library.
135 It is not able to send requested attributes in WHOIS command,
136 and also receive and process requested attributes. Added
137 silc_client_attribute_[add|del] and silc_client_attributes_get
138 functions. Added also `ignore_requested_attributes' to the
139 SilcClientParams to not use attributes in client. Affected
140 files are lib/silcclient/command.c, client_attrs.[ch],
141 silcclient.h, client_internal and client.[ch].
143 * Changed the silc_client_get_client_by_id to support Requested
144 Attributes, it takes them as argument now. Affected file
145 is lib/silcclient/silcclient.h, and idlist.c.
147 * Added -details option to WHOIS command in Irssi SILC Client
148 to support the requested attributes. By default it requests
149 all attributes. Affected file lib/silcclient/command.c and
150 irssi/doc/help/in/whois.in.
152 Tue Oct 8 17:58:28 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

157 silcd/server_query.c.
159 Mon Oct 7 18:25:35 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
161 * Changed the silc_attribute_payload_encode to support list
162 of attributes (function may be called several times to add
163 a new attribute). Removed the silc_attribute_payload_encode_list
164 function. The encoding function now also automatically encodes
165 the data, so the caller does not need to do that. Affected
166 files lib/silccore/silcattrs.[ch].
168 * Added support for replying on behalf of the user to the
169 Requested Attributes in WHOIS command in the server. Affected
170 file silcd/server_query.c.

178 decryption error has occurred. Affected file silcd/server.c.
180 * Fixed a bug in backup router IP address comparison in
181 silc_server_backup_get.
183 Save now also the port of the server/router and use that
184 in comparison as well. Affected file silcd/server_backup.c.
186 * Normal server now reconnects to backup router automatically
187 if connection is lost to it. Affected file silcd/server.c.
189 Thu Sep 26 13:51:02 CEST 2002 Pekka Riikonen <priikone@silcnet.org>

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

268 file lib/silcutil/silcutil.[ch].
270 * Added STATS command to client library and Irssi SILC client.
271 Patch provided by Ville Räsänen <ville.rasanen@iki.fi>.
273 Wed Sep 11 09:22:00 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
275 * Assure that channel key is set before sending it. May
276 crash server otherwise. Affected file silcd/packet_send.c.
278 Tue Sep 10 09:50:08 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
280 * Assure that endless loop cannot happen with detached client
281 resolving on normal server. Added idlist status
282 SILC_IDLIST_STATUS_RESUME_RES. Affected files are
283 silcd/idlist.h and silcd/packet_receive.c.
285 Mon Sep 9 12:18:18 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
287 * Incoming file transfer request cannot use same session as
288 the sending session. This can happen when sending file to
289 yourself. Crashed the client on quit. Affected file
290 lib/silcclient/client_ftp.c. Bug #24.
292 Sun Sep 8 18:39:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
294 * Implemented the draft-riikonen-precense-attrs draft and
295 the Attribute Payload into the lib/silccore/silcattrs.[ch].
297 Sun Sep 8 13:13:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
299 * Distribute the SERVER_SIGNOFF notify also to local backup
300 routers from the primary router. The backup router may not
301 have the signing of local server directly connected and need
302 to know about the signoff. Affected file silcd/server_util.c.
304 * Use the primary router as the origin of the locally connected
305 server when it is disconnecting from the backup router since
306 that's where it really is coming from. Now the clients from
307 the disconnecting server are removed correctly and "shadow"
308 clients are not left to the backup router. Affected file
311 Sat Sep 7 22:26:50 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
313 * If normal server is standalone and found existing but disabled
314 channel, do not re-create the channel since it creates
315 duplicate same channels. Affected file silcd/server.c.
317 * Added anonymous client connections support to server. New
318 "anonymous" configuration option to ConnectionParams section
319 added. If set to true, the username and hostname information
320 of the client will be scrambled and anonymous user mode is
321 set automatically to the user. Affected files are
322 silcd/serverconfig.[ch], silcd/packet_receive.c and server.c.
324 Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
326 * In JOIN notify handling, mark that the cache entry of the
327 client cannot be expired. Can cause crashes on normal
328 server (asserts client->channels). Affected file is
329 silcd/packet_receive.c.
331 * From now on distribution versions are used as protocol versions
332 instead of by default using the Toolkit base version as protocol
333 version. Affected file prepare.
335 * Do not set the locally resolved hostname for local client
336 entry but take what server sends. This way the real hostname
337 is showed in WHOIS for yourself. Affected file is
338 lib/silcclient/idlist.c and lib/silcclient/client.c.
340 * Resolve local info with IDENTIFY when connecting to server.y
342 Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
344 * Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
345 for implied search (not needed on platforms which has native
346 pthreads library). Use --without-pthreads to disable threads.
347 Affected file is configure.in.pre
349 * Fixed --with-iconv on platforms which need to bypass (broken)
350 native iconv(). Affected file is configure.in.pre
352 Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
354 * Moved -C option parsing in Irssi SILC client at same time
355 as other options. The UI was initialized earlier and caused
356 problems on command line. Bug #16. Affected file is
357 irssi/src/silc/core/silc-core.c.
359 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
361 * Added global variable silc_log_timestamp that tells silclog
362 wether to print or not the timestamp in the logging files.
363 Affected file lib/silcutil/silclog.[ch].
365 * Added silcd configuration option Timestamp in the Logging
366 section. Affected file silcd/serverconfig.[ch],
367 doc/example_silcd.conf.in.
369 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
371 * Fixed fingerprint checking to check for entirely empty
372 fingerprint instead of two first bytes when determining
373 if it is set. Bug #18. Affected file silcd/command.c.
375 * Fixed duplicate PKCS name registering to not allow it.
376 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
378 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>

381 platforms, enable those commented out. Cleanups.
382 Affected file lib/silcmath/mpi/configure.in
384 Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>
386 * silc_rng_exec_command() left zombie processes if command
387 didn't generate any output. Affected file
388 lib/silccrypt/silcrng.c
390 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
392 * Rewrote iconv checking, introduce --with-iconv for systems
393 which rely on libiconv. Check if iconv() provided by libc
394 is good enough, otherwise demand libiconv. Affected file
397 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
399 * Search for ldopen() also in libc. This enables SIM support
400 on *BSD systems. Based on patch from Alex Zepeda. Affected
401 file configure.in.pre
403 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
405 * Don't call AM_CONDITIONAL conditonally for SILC_THREADS.

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

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

799 properly when disconnecting from server. Affected file
800 irssi/src/silc/core/client_ops.c.
802 Tue Jun 18 17:14:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
804 * When authenticating as founder during JOIN command, check
805 that the one authenticating becomes the only founder on the
806 channel. Affected file silcd/command.c.
808 * Better checking for founder mode setting when CUMODE_CHANGE
809 notify is received. Affected file silcd/packet_receive.c.
811 * Close all connections when shutting down the server by sending
812 DISCONNECT packet. Close all listeners too when shutting
813 down the server. Affected file silcd/server.c.
815 * Handle DISCONNECT packet correctly in client library by
816 calling the "disconnect" client operation. Affected file
817 lib/silcclient/client.c.
819 * Handle local errors correctly during resuming. Affected
820 file lib/silcclient/client.c.

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

888 The one that authenticated will become founder and anyone
889 else is demoted. Affected file silcd/command.c.
891 * Added error printing of any error that has occurred during
892 any command in client library. Affected file is
893 irssi/src/silc/core/client_ops.c.

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

1582 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1584 * Some client implementations quit network by doing first LEAVE
1585 and then immediately SIGNOFF (like Bombyx). We now do check
1586 after a short time after LEAVE notify and check whether the
1587 client is still valid after LEAVE, and if not we remove it from
1588 cache. Affected file is lib/silcclient/client_notify.c.
1590 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1592 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1593 it's good not to have security holes here.
1595 * Fixed a negative refcount situtuation for the config context.
1596 Affected file is silcd/serverconfig.c.
1598 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1600 * ROBOdoc documented lib/silcutil/silcutil.h.
1602 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1604 * Optimized even more the SilcPacketContext structure. Now
1605 totally saved 16 bytes of memory per context after optimization.
1606 Affected files are lib/silccore/silcpacket.[ch].
1608 * Made strict checks for valid SILC IDs. Affected file is
1609 lib/silccore/silcid.c.
1611 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1613 * Changed the object argument for silc_cipher_register,
1614 silc_hash_register, silc_hmac_register and silc_pkcs_register
1615 to const. Affected files are lib/silccrypt/silccipher.[ch],
1616 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1618 * Changed the silc_get_username and silc_get_real_name to
1619 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1621 * Fixed the Irssi SILC Client to use the silc_get_username and
1622 silc_get_real_name insted of glib routines since the glib
1623 routines only corrupt stack. Fixes the Irssi SILC to work in
1624 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1626 * Fixed the Irssi to not use g_get_home_dir since it crashes
1627 or returns garbage on cygwin and corrupts stack. Added function
1628 get_home_dir to Irssi routines. Affected files are
1629 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1631 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1633 * Made some structure optimizations. SFTP memory FS MemFSEntry
1634 entry structure. Optimized SilcTask structure. Optimized
1635 SilcPacketContext structure.
1637 Affected files lib/silcsftp/sftp_fs_memory.c,
1638 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1640 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1642 * And yet again reverted back the config thing since Johnny
1643 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1646 * Fixed memory leaks from config object. Affected files are
1647 silcd/serverconfig.[ch].
1649 * Added support for adding new connections to the server in rehash.
1650 After rehash they take effect.
1652 Added support for changing the maximum allowed connections in
1653 rehash. The number can grow but going smaller is not supported.
1655 Added function silc_server_num_sockets_by_remote to the
1656 silcd/server_util.[ch].
1658 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1660 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1662 * Added preliminary checking during config parsing for a valid
1663 public/private key and removed further checks in the code.
1664 Affected files are silcd/serverconfig.[ch], server.c.
1666 * Moved functions silc_server_drop() and silc_server_daemonise()
1667 from server.c to silcd.c since they are stricly related to
1668 the application activity.
1670 * Reverted a small part of the automatic ref/unref since
1671 it caused a double unref in some situations. Affected
1672 files are silcd/silcd.[ch], server.c, serverconfig.c.
1674 * Added some .cvsignore files in the lib directory.
1676 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1678 * Fixed silc_net_gethostbyaddr to correctly resolve by
1679 address. Affected file lib/silcutil/silcnet.c.
1681 * Fixed the notify relaying to client. The HMAC to be used
1682 with relayed packets ws wrong and caused decryption failure
1683 at the client end. Affected file is silcd/packet_receive.c.
1685 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1687 * Created new branch silc_protocol_1_0_branch.
1689 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1691 * Changed the silc_server_config_* routines to be SilcServer
1692 independent. They are now officially application specific code
1693 and not part of generic server implementation. Affected files
1694 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1696 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1698 * Added automatic referencing of config context in the
1699 silc_server_config_alloc, and automatic unreferencing in the
1700 silc_server_config_destroy. Affected files are
1701 silcd/serverconfig.[ch], silcd/silcd.c.
1703 * Fixed the silc_log_quick handling in the logging routines.
1704 It didn't log quickly when it was TRUE. Affected file is
1705 lib/silcutil/silclog.c. Also the flush delay was set even
1706 if it was 0 in config file. Affected file is
1707 silcd/serverconfig.c.
1709 * Added support for changing key pair of the server in rehash.
1710 Affected file silcd/server.c.
1712 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1714 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1715 too early, before getting the channel entry. Affected file
1716 is silcd/packet_receive.c.
1718 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1720 * Added functions silc_server_config_[ref/unref], these are used
1721 to prevent that the config object is destroyed.
1723 No longer directly affect global variables silc_log_quick and
1724 silc_log_delay, they are first cached inside the config object
1725 and then applied with silc_server_config_setlogfiles().
1727 silc_server_config_set_defaults() is now internal to
1728 serverconfig.c, there are no reasons to show this internal stuff
1731 Affected files are silcd/serverconfig.[ch].
1733 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1734 fprintf's to stderr, since some code may be executed again after
1735 the server went into the background. Affected files are
1738 * Added rehash support. Added function silc_server_rehash() that
1739 will perform all the basic tasks of the rehashing procedure.
1741 * Added command line option `-x, --hexdump'. This will enable the
1742 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1743 The option `--hexdump' implies `--debug'.
1745 * Fixed a bad bug in the logging APIs (silcutil library) where
1746 the application would crash after calling silc_log_reset_all().
1748 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1750 * Fixed the KICKED notify handling in client library to
1751 correctly remove the channel and all entries from the
1752 channel when I was kicked. This bug crashed the client.
1754 Fixed yet another but in KICKED notify handling to remove
1755 the kicked client correctly from the channel.
1757 Affected file is lib/silcclient/client_notify.c.
1759 * Fixed a minor bug in looking up correct client entry
1760 in KICKED notify in server. Affected file is
1761 silcd/packet_receive.c.
1763 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1764 sources correctly to distribution. Fixes --with-gmp option.
1766 * Removed the manual rehashing from ID Cache, and changed it
1767 to use the SILC Hash Table's auto rehash feature. Affected
1768 file is lib/silccore/silcidcache.c.
1770 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1772 * Fixed a bug in the silc_client_nickname_format function that
1773 handles the multiple same nickname formatting. Two clients
1774 with same nickname caused problems after the first one left
1775 and rejoined. It didn't format the nickname correctly.
1776 Affected file is lib/silcclient/idlist.c.
1778 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1780 * Don't change the topic if olod topic is same as new one.
1781 Affected file is silcd/packet_receive.c.
1783 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1785 * Added cross-reference support to the SILC Documentation
1786 generator. All types across all HTML files are now cross-
1787 referenced. Affected files util/robodoc/generator.c and
1788 scripts/silcdoc/silcdoc.
1790 * Added file lib/silcutil/silctypes.h to include all the
1791 arithmetic type definitions and some macros. Removed
1792 includes/bitmove.h and moved macros to silctypes.h.
1794 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1796 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1798 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1800 * Added `type' argument to silc_id_payload_parse_id function which
1801 now returns the type of the ID to the sent pointer. Affected
1802 file is lib/silccore/silcid.[ch].
1804 * Added check for CMODE_CHANGE notify type that mode change is
1805 allowed by the sender. Affected file silcd/packet_receive.c.
1807 * Added check for CUMODE_CHANGE notify type that mode change is
1808 allowed by the sender. Affected file silcd/packet_receive.c.
1809 Added the ID type as CUMODE_CHANGE notify type as argument
1810 to the `notify' client operation. Affected files are
1811 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1813 * Added function silc_client_add_server to the client library.
1814 Added support for resolving also channel and server info when
1815 received unknown entity in notify packet. Affected files are
1816 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1818 * Added function silc_command_get_status to return the command
1819 status from the command reply's argument payload. Affected files
1820 are lib/silccore/silccommand.[ch].
1822 * Added check for KICKED notify type that the kicking is
1823 allowed by the client. Affected file silcd/packet_receive.c.
1825 * Created function silc_get_input which can be used to get input
1826 (echo on or off) from user on command line. Affected files are
1827 lib/silcutil/silcutil.[ch].
1829 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1831 * Optimized silc_server_packet_relay_to_channel function.
1832 Added new function silc_channel_message_payload_encrypt which
1833 can be called directly if channel message payload needs to
1834 be encrypted and is already encoded (no need to call _encode
1835 function). Packet relaying is now done by router without any
1836 extra memory allocations. Affected files are
1837 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1838 silcd/packet_send.c.
1840 * Fixed the INVITE notify handling. It took wrong arguments
1841 as invite list and invite delete. Affected file is
1842 silcd/packet_receive.c.
1844 * Added check for TOPIC_SET notify type that the topic change is
1845 allowed by the client. Affected file silcd/packet_receive.c.
1847 * Added check for INVITE notify type that inviting is allowed by
1848 the client. Affected file silcd/packet_receive.c.
1850 * Changed the silc_server_client_on_channel to return the
1851 SilcChannelClientEntry as well. Moved the function
1852 silc_server_check_cmode_rights to server_util.[ch].
1853 Affected files are silcd/server_util.[ch], silcd/command.c.
1855 * Added function silc_server_check_umode_rights to check whether
1856 changing client's user mode is allowed. Added check for
1857 UMODE_CHANGE notify type that the umode change is allowed
1858 by the client. Affected files are silcd/server_util.[ch],
1859 silcd/packet_receive.c and silcd/command.c.
1861 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1863 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1864 ID length. It ignored that ID can be IPv6 based as well.
1865 Affected file lib/silccore/silcpacket.h.
1867 * Fixed the silc_id_id2str and silc_id_str2id to take the
1868 IPv6 address offset's into consideration. Affecte file is
1869 lib/silccore/silcid.c.
1871 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1873 * Fixed the internal Unix scheduler functions to check for
1874 NULL context they may receive. The affected file is
1875 lib/silcutil/unix/silcunixschedule.c.
1877 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1879 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1880 can specify different directory with --home command line
1881 parameter. Affected files irssi/src/silc/core/client_ops.c,
1884 * SILC-specific commands aren't now executed if the active server
1885 isn't of SILC-type, so there won't be problems with having
1886 IRC and SILC protocol support in same client. Affected files
1887 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1890 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1892 * Improved the signal support in SILC Schedule. Added new
1893 function silc_schedule_signal_call which is used by application
1894 to mark a signal to be called. It is now safe to perform
1895 any kind of tasks in signal callbacks since it is guaranteed
1896 that the application specified signal callback is called
1897 after the signal is over. Affected files are
1898 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1900 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1902 * Added `name' field to SilcChannelPrivateKey to represent
1903 application given name for the key. Moved also the context from
1904 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1905 Added the `name' argument also to the function
1906 silc_client_add_channel_private_key.
1908 Added function silc_client_current_channel_private_key to set the
1909 current channel private key in use.
1911 Added "change" command to KEY command which can be used to change
1912 the current channel private key. Bound the command also to
1913 alt+K (Alt+Shift+k).
1915 Also affected files lib/silcclient/client_channel.c,
1916 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1918 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1920 * Added silc_rng_get_byte_fast function in to the
1921 lib/silccrypt/silcrng.[ch].
1923 * Changed the interface of silc_packet_assemble and the
1924 silc_packet_send_prepare. If silc_packet_assmble is now
1925 called the application does not call silc_packet_send_prepare
1926 because the library will call it automatically. These
1927 interfaces now also return a reference to the outgoing buffer
1928 which includes the assembled packet, which the application can
1929 use to encrypt the packet.
1931 Affected files are lib/silccore/silcpacket.[ch],
1932 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1933 silcd/packet_send.c, server_backup.c and packet_receive.c.
1935 * Fixed a packet sending bug on very high load, where outgoing
1936 packet queue wasn't handled correctly and packets got corrupted.
1937 Affected files are lib/silcutil/*/silc*sockconn.c,
1938 lib/silcclient/client.c and silcd/server.c.
1940 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1942 * Added macro SILC_PACKET_DATALEN which can be used during
1943 packet assembling to check whether the data to be added to
1944 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1945 len is truncated until it fits it.
1947 Added checks for maximum length of channel message payload and
1948 private message payload also.
1950 Added checks for maximum packet length in server and in
1953 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1954 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1955 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1956 lib/silcclient/client_prvmsg.c.
1958 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1960 * Added silc_server_packet_queue_purge call to the
1961 silc_server_disconnect_remote to assure that all data in the
1962 queue before disconnecting is sent to the network. Affected
1963 file silcd/server.c.
1965 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1967 * Added the deleting of server's own ID cache entry to the
1968 silc_server_free function. Free also everything else that
1969 has been allocated in silc_server_init. The affected file
1972 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1974 * Added functions silc_parse_version_string, silc_version_to_num,
1975 and silc_ske_parse_version to parse SILC protocol style version
1976 strings. Affected files lib/silcutil/silcutil.[ch] and
1977 lib/silcske/silcske.[ch].
1979 * Added new configuration params: version_protocol, version_software
1980 and version_software_vendor to specify what version the remote
1981 host must at least be to be able to connect to server. The vendor
1982 string can be regex matched too. Added new function
1983 silc_server_connection_allowed to check maximum number of allowed
1984 connections, and allowed versions for incoming connections.
1985 Affected files are silcd/server.c, server_util.[ch] and
1988 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1990 * Added preliminary support for signals in scheduler. The
1991 signals we care about are now blocked always when the scheduler
1992 is locked. This way we can synchronise the use of signal with
1993 scheduler. It is guaranteed that when signal occurs the scheduler
1994 is not locked, and thus new tasks can be safely added to the
1997 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1998 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1999 Added new platform specific routines
2000 silc_schedule_internal_signals_[un]block and
2001 silc_schedule_internal_signal_[un]register.
2003 Added new functions to SILC Schedule API:
2004 silc_schedule_signal_[un]register. Each signal that application
2005 is going to use should be registered to the scheduler.
2007 Affected files are lib/silcutil/silcschedule.[ch],
2008 lib/silcutil/*/silc*schedule.c.
2010 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2012 * Check for unauthenticated client and server in the
2013 silc_server_new_client and silc_server_new_server functions.
2014 Affected file silcd/packet_receive.c.
2016 * Added function silc_string_is_ascii to check whether given
2017 string is 7-bit ASCII string. Affected files are
2018 lib/silcutil/silcutil.[ch].
2020 * Added function silc_id_is_valid_server_id into the
2021 silcd/serverid.c and added checking for valid Server ID's in
2022 silc_server_new_server. The Server ID must always be based
2023 on the server's public IP address.
2025 * Added logging of DISCONNECT packet message in the server.
2026 Affected file silcd/server.c.
2028 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2030 * Changed all library interfaces that use Global RNG to also
2031 accept SilcRng as argument. Affected files are
2032 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
2033 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
2034 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
2035 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
2036 lib/silccrypt/rsa.c.
2038 * Added function silc_pkcs_generate_key to the
2039 lib/silccrypt/silcpkcs.[ch] for applications so that they
2040 don't need to do pkcs->pkcs->init calls anymore.
2042 * Remove SilcSocketConnection from the SFTP API since it really
2043 wasn't needed there. The application has the information
2044 saved in its contexts anyway and the SFTP layer doesn't need
2045 know about it. Affected files lib/silcsft/silcsftp.h and
2046 lib/silcsftp/sftp_[server/client].c.
2048 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
2049 The SilcSimContext is not SilcSim.
2051 * Fixed possible buffer overflows in silc_id_render in the
2052 lib/silcutil/silcutil.c.
2054 * On EPOC the global crypto module lists are not used at all
2055 in the crypto library. Added support for using the constant
2056 algorithm list on EPOC. Affected files are
2057 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
2060 * Fixed the handling of third parameter of KICKED notify, since
2061 it was mistakenly updated to SILC Protocol 1.0 even though it
2062 is to be included in 1.1. Since it is not in 1.0 it is not
2063 mandatory, and this fix now handles it only if it is provided,
2064 and it is not error if it is not provided. Affected file
2065 lib/silcclient/client_notify.c.
2067 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2069 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
2070 client. Affected file irssi/src/silc/core/client_ops.c.
2072 * Merged with Irssi 0.8.4 from irssi.org CVS.
2074 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2076 * Check for valid socket connection in client entries before
2077 sending any messages. Fixes a crash, but doesn't fix some

2103 hash public keys and compare public keys in hash table. Affected
2104 file lib/silcutil/silcutil.[ch].
2106 * Added support for specifying multiple public keys for Client
2107 connection section in server configuration file. This makes it
2108 possible to accept multiple public keys from same host, or to
2109 make a section that accepts any incoming host, and have the
2110 accepted public keys listed in the section.
2112 Added functions silc_sever_[find/get]_public_key, added the
2113 support for this actually to all connection sections but only

2137 from single host, by checking also the type of the connection.
2138 Fixed also the comparison of number of connections and number
2139 of allowed connections. Affected files are silcd/server.c,
2142 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2221 application does not need to define them. Affected file
2222 includes/silcincludes.h.
2224 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
2225 old name went against naming convention. Applications now
2226 include "silcclient.h" instead of "clientlibincludes.h".
2227 Removed includes/clientlibincludes.h, it is redundant now.
2229 * Renamed includes/version.h to silcversion.h.
2231 * Added really preliminary support for OS/2 into the util
2232 library. Only thread & mutex API is implemented, others
2233 are still to be implemented. Created the lib/silcutil/os2/

2267 * Added `user_count' to the SilcChannelEntry which now tells the
2268 number of users on the channel. The user count is now saved
2269 in normal server of global channels as well. Affected files
2270 silcd/server.c, idlist.h, packet_receive.c and command.c.
2272 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
2273 include file utility functions.
2275 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
2276 instead of calling directly OS routines.

2288 * ROBOdoc documented the lib/silcske/silcske.h, and improved
2289 the SKE interface a bit.
2291 * Fixed padding problem in PKCS#1. The padding was not actually
2292 random since the random number generator was used incorrectly.
2293 This security bug affects only when encrypting with PKCS#1, and
2294 it is not currently used at all in SILC. SILC only use signing
2295 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
2297 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2355 is now done in silc_core_init() which also fixes autoconnecting
2358 Affected files irssi/src/silc/core/silc-core.c,
2359 irssi/src/fe-text/silc.c.
2361 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2363 * Added new configuration options and blocks:
2364 keepalive_secs, reconnect_count, reconnect_interval,
2365 reconnect_interval_max, reconnect_keep_trying and
2366 require_reverser_lookup. Added ConnectionParam block, and
2367 implemented the connection parameters when connecting as
2368 initiator and when accepting connections as responder.

2380 the connection configuration object from the SilcServerConnection
2381 object instead of finding it during the connecting phase.
2382 Added the configuration object to SilcServerConnection struct.
2383 Affected files silcd/server_internal.h, server.c.
2385 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2387 * Add the client on channel after it was resolved at the
2388 channel message receiving, and it was not already on the
2389 channel. Affected file lib/silcclient/client_channel.c.
2391 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2407 authentication to be set at the same time.
2409 Added `prefer_passphrase_auth' setting in config file which
2410 can be used to set to prefer passwd auth if both passwd and
2411 public key is set. If not set, public key is preferred.
2412 This has effect only when being initiator (responder will try
2415 Added support for authentication with passphrase and public key
2416 at the same time. The passphrase is tried first always since
2417 it is faster to check.
2419 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2421 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2467 * Fixed the file transfer's key agreement payload to include
2468 zero port also if the hostname is NULL because it could not
2471 Call file transfer monitor callback now also if error occurs
2472 during key agreement protocol.
2474 Changed the silc_client_file_send interface to return the
2475 SilcClientFileError instead of session id. The session ID
2476 is returned into pointer provided as argument.

2493 file lib/silcutil/silclog.c.
2495 * Fixed the channel message payload decryption in the function
2496 silc_channel_message_payload_decrypt to not modify the original
2497 buffer before it is verified that the message decrypted
2498 correctly. Otherwise, next time it is called with correct
2499 channel key it won't encrypt since the payload is corrupted.
2500 Affected file lib/silccore/silcchannel.c.
2502 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2514 * Fixed a bug in hash table internal routine for traversing
2515 the table with foreach callback. The current entry may
2516 become invalid in the callback but it was referenced after
2517 the callback returned.
2519 Do not allow auto rehashing of hash table during the
2520 silc_hash_table_foreach operation, for same reasons as it is
2521 not allowed for SilcHashTableList. Affected files are
2522 lib/silcutil/silchashtable.[ch].
2524 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

2545 users list to SilcHashTable. The affected files are
2546 lib/silcclient/idlist.[ch].
2548 * Fixed a bug in hash table tarversing. While the hash table
2549 is traversed with SilcHashTableList the table must not be
2550 rehashed. It is now guaranteed that auto rehashable tables
2551 are not rehashed while tarversing the list. Also defined that
2552 silc_hash_table_rehash must not be called while tarversing
2553 the table. Added function silc_hash_table_list_reset that must
2554 be called after the tarversing is over. The affected files are
2555 lib/silcutil/silchashtable.[ch].
2557 * Changed all hash table traversing to call the new
2558 silc_hash_table_list_reset in server and in client library.
2560 * Added function silc_client_on_channel to return the
2561 SilcChannelUser entry if the specified client entry is joined
2562 on the specified channel. This is exported to application as
2563 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

2568 server. The notify for mode change must be sent always and
2569 not only if !cmd->pending. Affected file silcd/command.c.
2571 * Fixed the WHOWAS command's reply sending to support the
2572 lists correctly. Affected file silcd/command.c.
2574 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2576 * When sending JOIN command to router for processing the
2577 sender's old command identifier was not saved back to the
2578 sender's command context, fixed now. The affected file is
2581 * Create the key in JOIN command of the router did not return
2582 the channel key, added check for this. Affected file is
2585 * Fixed a channel ID update bug in JOIN command reply. Do
2586 not directly upgrade the ID but call the function
2587 silc_idlist_replace_channel_id if the ID was changed.
2588 Affected file silcd/command_reply.c.
2590 * Fixed memory leaks from command calling if it would fail.
2591 Affected file silcd/command.c.

2598 new silclist.h and silcdlist.h, all extern inline changed to
2601 * Removed dotconf from lib/dotconf, not needed anymore.
2603 * Removed TRQ from lib/trq, not needed anymore.
2605 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2606 with server connections. Later this will be configurable
2607 in config file after new config file is done. Affected file
2610 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2612 * Fixed a crash in server related to channel announcements.
2613 Affected file silcd/server.c.
2615 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2617 * Fixed memory leaks in silc_server_create_new_channel*
2618 functions. Affected file silcd/server.c.
2620 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2621 which ID was changed. This way the router will send the
2622 user list for the channel again, and server won't be in
2623 desync in some rare circumstances. Affected file is
2624 silcd/packet_receive.c.
2626 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2628 * Check for NULL socket pointer in the function
2629 silc_server_packet_send_to_channel_real. Affected file
2630 silcd/packet_send.c.
2632 * Fixed the BAN notify handling to correctly remove ban
2633 list. Affected file silcd/packet_receive.c.
2635 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2637 * Fixed some header addition to Toolkit distribution in
2638 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2640 * Added lib/silcclient/client_ops_example.h as an template
2641 file for application programmers to quickly start using
2642 the SilcClientOperation functions in their application.
2643 Updated the lib/silcclient/README as well to tell about this
2644 nice file made available.
2646 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2648 * Call silc_server_remove_from_channels when removing client
2649 entry when NO_SUCH_CLIENT_ID was received. Affected file
2650 is silcd/command_reply.c.
2652 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2654 * Added server & router operator statistics updating. Affected
2655 file silcd/packet_receive.c and silcd/command.c.
2657 * Fixed the SERVER_SIGNOFF notify handling on normal server
2658 not to save the history information for clients. Same was
2659 fixed earlier in remove_clients_by_server function, but not
2660 here. Affected file silcd/packet_receive.c.
2662 * Raised the default connection-retry count from 4 to 7 in
2663 server. Affected file silcd/server.h.
2665 * Cancel any possible reconnect timeouts when we start the
2666 key exchange. Affected file silcd/server.c.
2668 * Do not reconnect on connection failure when SCONNECT was
2669 given. Affected files silcd/server.[ch].
2671 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2673 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2675 * Fixed the NICK command to always give the unformatted
2676 nickname to the one giving the NICK command. If unformatted
2677 nickname is cached already it will be formatted and the
2678 local entry will always get the unformatted nickname.
2679 Affected file lib/silcclient/idlist.c.
2681 * Fixed some double frees from client library commands.
2682 Affected file is lib/silcclient/command.c.
2684 * Fixed CUMODE command in server to assure that no one can
2685 change founder's mode than the founder itself, there was a
2686 little bug. Affected file silcd/command.c.
2688 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2690 * Removed the SilcClientCommandDestructor from the client
2691 libary, it is not needed anymore. Affected files are
2692 lib/silcclient/silcapi.h, command[_reply].[ch],
2693 client_notify, idlist.c.
2695 * Fixed GETKEY command to first resolve client, and then
2696 resolve the server only if the client was not found, instead
2697 of resolving both at the same time. Affected file is
2698 lib/silcclient/command.c.
2700 * Added silc_client_start_key_exchange_cb and lookup the
2701 remote hostname and IP address before starting the key
2702 exchange with server. The affected file is
2703 lib/silcclient/client.c.
2705 * The server's public key is now saved using the IP address
2706 of the server and not the servername for the filename.
2707 The hostname public key filename is checked as an fall back
2708 method if the IP address based filename is not found.
2710 Fixed the GETKEY command to save the fetched server key
2711 in correct filename.
2713 Print the remote server's hostname now when new key is
2714 received during connection process. Affected file is
2715 irssi/src/silc/core/client_ops.c.
2717 * Return always our own public key to the client if it asks
2718 for it with GETKEY command. Affected file silcd/command.c.
2720 * Removed the use_auto_addr variable from default config
2721 file since it was in wrong section. Affected file is
2724 * Fixed TOPIC_CHANGE notification to not route it when it
2725 was sent using silc_server_send_notify_to_channel function.
2726 Affected file silcd/command.c.
2728 * Fixed silc_server_send_notify_kicked to send the kicker's
2729 Client ID also, it was missing. Affected files are
2730 silcd/command.c, silcd/packet_send.[ch].
2732 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2734 * Do not save client history information in SERVER_SIGNOFF.
2735 Fixes the bug in normal server that it does not detect
2736 the client becoming valid after the server becomes back
2737 online. Affected file silcd/server_util.c.
2739 * Added `sock_error' field into the SilcSocketConnection
2740 context. When error occurs during socket operation (read
2741 or write) the error is saved. Added also new function
2742 silc_socket_get_error to return human readable socket error
2743 message. Affected files are lib/silcutil/silcsockconn.[ch],
2744 lib/silcutil/unix/silcunixsockconn.c, and
2745 lib/silcutil/win32/silcwin32sockconn.c.
2747 * The server now prints the socket error message in the
2748 signoff for client. Affected file silcd/server.c.
2750 * Fixed the `created' channel information sending from router
2751 to server in JOIN command. Checks now whether the channel
2752 really was created or not and set it according that.
2754 Fixed the JOIN command to use the client entry's current
2755 ID during the joining procedure instead of the one it sent
2756 in the command (it is checked though), since it can change
2757 between the packet processing and command processing, and
2758 would just case unnecessary pain in the client end. Affected
2759 file silcd/command.c.
2761 * Fixed a channel key payload sending to use correct channel
2762 ID when the server was forced to change the channel's ID by
2763 router. Router sent the key payload with the old Channel ID.
2764 Affected file silcd/packet_receive.c.
2766 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2768 * Call silc_server_save_channel_key only if the key payload
2769 was provided in the JOIN command's command reply. Affected
2770 file silcd/command_reply.c.
2772 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2774 * Fixed silc_mp_sizeinbase to return the value correctly with
2775 MPI. Affected file lib/silcmath/mp_mpi.c.
2777 * Fixed the stop_server signal to correctly stop the scheduler
2778 and gracefully stop the server when SIGTERM or SIGINT signals
2779 are received. Affected file silcd/silcd.c.
2781 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2783 * Simple handling of TERM and HUP signals. Also added some log
2784 flushing call around. Affected file is
2787 * Fixed small bugs in silclog.c. Now buffering output will take
2788 effect after 10 seconds since startup: This will ensure that
2789 no important startup messages are lost. Also output redirection
2790 will preserve original format ([Date] [Type] message).
2791 Affected file is lib/silcutil/silclog.c.
2793 * Added two options to the config file, in the logging section:
2794 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2795 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2797 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2799 * Do not print the warning about log files not being initialized
2800 more than once to avoid excess logging. Affected file is
2801 lib/silcutil/silclog.c.
2803 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2804 the SIM copying in make install in Makefile.am.pre.
2806 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2808 * Rewritten silclog APIs. Globally interesting changes follows:
2809 silc_log_set_files() changed to silc_log_set_file().
2810 silc_log_set_callbacks() changed to silc_log_set_callback().
2811 ROBOdoc documented silclog header file.
2812 SilcLogCb now returns bool to wether inihibit the default
2813 handler or not (to keep the old behaviour return always TRUE).
2814 The new APIs should also fix the problem of the
2815 silcd_error.log file that was written in the current directory.
2818 Log files streams will remain opened after silc_log_set_file()
2819 call, means less CPU usage notably on high traffic servers.
2820 File streams are now full buffered, and flushed to the disk
2821 every 5 minutes, lesses HD activity and CPU usage.
2822 Messages can be redirected, allowing admins to configure
2823 one single logfile for all server messages.
2824 the silc_log_quick global variable to activate fast-logging.
2825 Affected files lib/silcutil/silclog.[ch]
2827 * Changed some code to conform new silclog APIs. Affected
2828 files are doc/example_silcd.conf.in, silcd/server.c
2829 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2832 * Fixed a memory leak that could occur in some situations.
2833 Affected file silcd/serverconfig.c.
2835 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2837 * Added the silc_client_del_client to remove the client from
2838 all channels as well. Affected file lib/silcclient/idlist.c.
2840 * Fixed the client library to correctly remove the client
2841 from all channels when the client entry is being destroyed.
2842 Affected file lib/silcclient/client_notify.c, command.c.
2844 * Added auto-nicking support to the client library. If the
2845 applicatio now sets client->nickname it will be sent to the
2846 server after connecting by the library. This way for example
2847 SILCNICK (or IRCNICK) environment variables will have effect
2848 and always change the nickname automatically to whatever
2849 it is wanted. Affected file lib/silcclient/client.[ch].
2851 * Renamed silc_server_command_bad_chars to the
2852 silc_server_name_bad_chars and moved it to the
2853 silcd/server_util.[ch]. Added also new function
2854 silc_server_name_modify_bad to return nickname that
2855 includes bad characters as new nickname without those
2856 bad characters. This check and modify is now used in
2857 silc_server_new_client when the username is initially set
2858 as nickname, so it must be checked to be valid nickname.
2859 Affected file silcd/packet_receive.c.
2861 * The nickname length is now taken from the packet for real
2862 and not trusted to strlen() since it clearly can return
2863 wrong length for nickname including bad characters. This
2864 also applies to channel names. Affected file silcd/command.c.
2866 * Removed the lib/silcsilm/modules directory. Modules are now
2867 compiled into the lib/silcsim. Fixed the copying of the
2868 modules to follow symbolic links in Makefile.am.pre.
2870 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2872 * Fixed silc_string_regexify list creation. Fixes bugs with
2873 BAN and INVITE commands in server. The affected file is
2874 lib/silcutil/unix/silcunixutil.c.
2876 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2878 * Removed the command destructor entirely from the server's
2879 command and command reply routines. It is not needed, and
2880 its usage was buggy and caused crashes. Affected files are
2881 silcd/command[_reply].[ch].
2883 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2885 * Cancel protocol and NULL sock->protocol if timeout
2886 occurred during protocol. Affected file silcd/server.c.
2888 * Cancel protocol timeouts always before calling the final
2889 callback, to assure that after final callback is called
2890 no other state will be called for the protocol anymore.
2891 Affected file silcd/protocol.c.
2893 * Print error log if incoming connection configuration could
2894 not be found. Affected file silcd/server.c.
2896 * Fixed JOIN command to correctly save the founder mode
2897 to the client on normal SILC server, when the channel
2898 was created by the router. Affected file silcd/command.c.
2900 * Fixed LIST command (hopefully) to send correct reply
2901 packets. Affected file silcd/command.c.
2903 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2905 * The silc_packet_receive_process now returns FALSE if the
2906 read data was invalid packet, and TRUE if it was ok.
2908 The server now checks that if unauthenticated connection
2909 sends data and its processing fails the server will close
2910 the connection since it could be a malicious flooder.
2912 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2914 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2916 * Make sure the warning about error opening a log file is
2917 printed only once and not everytime it fails (produces
2918 too much useless log). Affected file lib/silcutil/silclog.c.
2920 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2922 * Made the silc_server_daemonise() function more readable.
2923 Affected file silcd/server.c.
2925 * Pid file is now optional, the user may comment it out from
2926 the config file. Removed define SILC_SERVER_PID_FILE, we
2927 don't need a default any longer. Affected file
2928 configure.in.pre, lib/Makefile.am.pre.
2930 * Make some use of the pid file. The server now dies at startup
2931 if it detects a valid pid file on his path. The server would
2932 die anyway in this circumstance, because of the bind() failure.
2933 Affected file silcd/silcd.c.
2935 * No longer compiling lib/dotconf.
2937 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2939 * Fixed JOIN command parsing not to crash. Affected file
2940 lib/silcclient/command.c.
2942 * Fied the NICK_CHANGE notify to add the new client entry
2943 even it is resolved. This removes an <[unknown]> nick
2944 thingy bug in the client. Affected file is
2945 lib/silcclient/client_notify.c.
2947 * Do not try to allocate 0 bytes (efence does not like it)
2948 in lib/silccore/silccomand.c when encoding payload.
2950 * Do not take IRCNICK as nickname in Irssi SILC client since
2951 it is not possible to set nickname before hand connecting
2952 the server (TODO has an entry about adding auto-nicking
2955 * Changed the silc_server_command_pending to check whether
2956 there already exists an pending entry with the specified
2957 command, command identifier and pending callback. This is
2958 to fix IDENTIFY and WHOIS related crashes that may register
2959 multiple pending commands with same identifier. Affected
2960 file silcd/command.c.
2962 * Fixed the server to reconnect to the router even if it
2963 was already reconnecting and EOF was received. This to
2964 fix a possibility that the server wouldn't ever try to
2965 auto-reconnect to the router. Affected file silcd/server.c.
2967 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2969 * Fixed the server's password authentication to use the
2970 length of the locally saved password, and not the one
2971 sent in the packet. Affected file silcd/protocol.c.
2973 * Fixed same password authentication problem in the
2974 Authentication Payload handling routines in
2975 lib/silccore/silcauth.c.
2977 * Yet another password authentication problem fixed with
2978 channel password handling in silcd/command.c.
2980 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2982 * If first character of string in silc_parse_userfqdn is '@'
2983 then do not parse it. Affected file is
2984 lib/silcutil/silcutil.c.
2986 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2988 * Fixed minor bug in IDENTIFY command reply sending, which
2989 caused various weird problems during JOIN when it was
2990 resolving names for users. Affected file silcd/command.c.
2992 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2994 * Fixed the IDENTIFY command reply sending to chech better valid
2995 clients. It was possible to send incomplete list of replies.
2996 Affected file silcd/command.c.
2998 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3000 * Added silc_client_command[s]_[un]register functions now to
3001 dynamically register the commands in client library. Removed
3002 the static table of commands. This allows the client library
3003 to call commands without causing the application to know about
3004 what commands library has called.
3006 Removed the INFO command reply kludge to detect when the command
3007 was called by library. Now library use its own command reply
3008 function for INFO command.
3010 Added function silc_client_command_call to call a command.
3011 Application can use it to call command, not access the structure
3014 Now all commands that are sent by the client library (not
3015 explicitly sent by application) use own command reply functions.
3017 Affected files around lib/silcclient/ and in
3018 irssi/src/silc/core/.
3020 * Fixed the WHOIS command reply sending to chech better valid
3021 clients. It was possible to send incomplete list of replies.
3023 Fixed the WHOIS and IDENTIFY to send the request to router
3024 if normal server did not do it and did not find any results.
3026 Affected file silcd/command.c.
3028 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3030 * Moved the internal data from SilcClient context into its
3031 own file, not accesible to application. Affected files
3032 lib/silcclient/client.h and lib/silcclient/client_internal.h,
3033 and other files in client library.
3035 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3037 * Added doc/examples installation target in Makefile.am.pre.
3040 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3042 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
3043 commands the found client entry will be removed from the
3044 cache, after notifying application about the error. Affected
3045 file lib/silcclient/command_reply.c.
3047 * Changed the /MSG to check for exact nickname user gave, and
3048 not let `nick' match `nick@host' if it is only one found. Now,
3049 user must type the exact nickname (like nick@host2) even if
3050 there are no more than one same nicks found. This is to avoid
3051 a possibility of sending nickname to wrong nickname since
3052 `nick' could match `nick@host'. Affected file is
3053 irssi/src/core/silc-servers.c.
3055 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3057 * Do not print "you are now server operator" or similar when
3058 giving /away command. Affected files are
3059 irssi/src/silc/core/client_ops.c, silc-servers.h.
3061 * Made the silc_server_command_pending_error_check to send
3062 the same command reply payload it received back to the
3063 original sender of the command. This way all arguments
3064 that was received by the server will be received by the
3065 client too. Affected file silcd/command.c.
3067 * Added the silc_idcache_add to return the created cache entry
3068 to a pointer. Affected file lib/silccore/silcidcache.[ch].
3070 * Add global clients to expire if they are not on any channel.
3071 This is because normal server will never know if they signoff
3072 if they are not on any channel. The cache expiry will take
3073 case of these entries. This is done by normal servers only.
3074 The affected files are silcd/command_reply.c,
3075 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
3077 * If server receives invalid ID notification for WHOIS or
3078 IDENTIFY and the ID exists in the lists, it is removed.
3079 Affected file silcd/command_reply.c.
3081 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
3082 in client then client entry that it matches is searched and
3083 the nickname is printed on the screen for user. Affected
3084 file irssi/src/silc/core/client_ops.c.
3086 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3088 * Use cache entry expire time in the LIST command reply to
3089 purge old entries from the cache after the LIST command
3090 reply has been received. This way we don't have non-existent
3091 entries in the cache for too long. Affected file is
3092 silcd/command_reply.c.
3094 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3096 * If we are normal server, and we've not resolved client info
3097 in WHOIS or IDENTIFY from router, and it is global client,
3098 we'll check whether it is on some channel. If it is not
3099 then we cannot be sure about its validity and will resolve it
3100 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
3101 file silcd/command.c.
3103 * Search channel by name (if possible) rather than by ID
3104 in IDENTIFY command's command reply. Affected file is
3105 silcd/command_reply.c.
3107 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3109 * Distribute to the channel passphrase in CMODE_CHANGE notify.
3110 Updated specs and implemented it. Affected file silcd/command.c,
3111 silcd/packet_send.c and silcd/packet_receive.c.
3113 * Implemented the <founder auth> payload handling in the JOIN
3114 command. If provided all conditions for channel joining
3115 except requirement to provide correct passphrase can be
3116 overrided by the channel founder. Updated the protocol specs.
3117 Affected file silcd/command.c.
3119 Added support for founder auth in JOIN command in client
3120 library. Fixed the parsing of the JOIN command now to support
3121 all options as they should be. The affected file is
3122 lib/silcclient/command.c.
3124 * Optimized the WHOIS and IDENTIFY commands to send the request
3125 to router only if it includes nicknames or other names. If
3126 they include only IDs then check the local cache first before
3127 routing. Affected file is silcd/command.c.
3129 * Added channels topic announcements. Affected file is
3130 silcd/packet_receive.c and silcd/server.c.
3132 * Fixed the silc_server_send_notify_topic_set to really destine
3133 the packet to channel. Affected file silcd/packet_send.c.
3135 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
3136 library. Affected file lib/silcclient/client_notify.c.
3138 * Added UMODE announcements. Affected file silcd/server.c.

3155 * ROBOdoc documented the lib/silcske/groups.h file and a
3156 bit changed the interface for better.
3158 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3160 * Update the client entry context in the ID cache after
3161 nick change. Affected file lib/silcclient/command.c.
3162 Fixes the CUMODE command when regaining founder privileges,
3163 and a little WHOIS problem.
3165 * Fixed silc_net_gethostbyname to correctly call the
3166 inet_ntop. Affected file lib/silcutil/silcnet.c.
3168 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3170 * Added IPv6 support checking to the configure.in.pre, added
3171 also --enable-ipv6 option to override the check. Affected
3172 file configure.in.pre.
3174 * The silc_thread_create now calls the start function
3175 directly if threads support is not compiled in. Removes
3176 ugly #ifdef's from generic code. Affected files are
3177 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
3179 * Added silc_net_gethostby[name/addr]_async to asynchronously

3191 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
3192 routines. Added silc_net_is_ip[4/6]. Affected file is
3193 lib/silcutil/unix/silcunixnet.c. All routines that take
3194 address as argument now supports both IPv4 and IPv6 addresses.
3196 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3198 * Fixed LIST command reply sending in server. Affected file
3201 * Server now sends the kicker's client ID in the KICK notify
3202 to the kicked client. Affected file silcd/command.c.
3204 * The client library now parses the kickers client ID and
3205 UI displays it. Affected files lib/silcclient/client_notify.c
3206 and irssi/src/silc/core/silc-channels.c, module-formats.c.
3208 * Made all payload parsing function prototypes consistent.
3209 They all take now const unsigned char * and uint32 pair as
3210 the payload data instead of SilcBuffer. Changes all around
3211 the source tree. Other unsigned char* -> const unsigned char*
3212 changes around the tree as well.
3214 * Optimized SFTP client and server packet sending not to
3215 allocate new buffer for each packet but to recycle the
3216 first allocated buffer. Affected files are
3217 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
3219 * Optimized the SFTP client to use SilcList instead of
3220 SilcDList for requests, because it is faster. Affected file
3221 is lib/silcsftp/sftp_client.c.
3223 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
3224 into lib/silccore/silcid.[ch].
3226 Renamed silcpayload.[ch] into silcargument.[ch].
3228 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3230 * If client entry is deleted with active key agreement
3231 session, abort the session.
3233 The silc_client_abort_key_agreement now calls the completion
3234 callback with new SILC_KEY_AGREEMENT_ABORTED status.
3236 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
3239 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3241 * Don't use __restrict in older GCC's. Affected file is
3242 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
3244 * silc_net_localhost now attempts to reverse lookup the
3245 IP/hostname. Affected file lib/silcutil/silcnet.c.
3247 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
3248 command. It can be used to gain founder privileges at
3249 the same time when joining the channel.
3251 Defined that the SILC_NOTIFY_TYPE_KICKED send the
3252 kicker's client ID as well. Updated protocol specs.
3254 Defined that the server must send SILC_COMMAND_IDENTIFY
3255 command reply with error status to client who sent
3256 private message with invalid client ID.
3258 Updated the protocol specification.
3260 * Added silc_server_send_command_reply to send any
3261 command reply. Affected file silcd/packet_send.[ch].
3263 * Added silc_id_payload_encode_data to encode ID payload
3264 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
3266 * The server now send IDENTIFY command reply with error
3267 status if client ID in private message is invalid. Affected
3268 file silcd/packet_receive.c.
3270 * Save the server key file with server's IP address in
3271 the filename instead of hostname. The affected file is
3272 irssi/src/silc/core/client_ops.c.
3274 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3276 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
3279 * Added libtool support for compiling shared objects in
3280 lib/silcsim. Affected file configure.in.pre and
3281 lib/silcsim/Makefile.am. Original patch by cras.
3283 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3285 * Pid file configuration, and server's config file fixes
3286 patch by toma. Updated CREDITS file.
3288 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3290 * Fixed silc_client_channel_message to not try to decrypt
3291 the message twice if it resolved the destination client
3292 information. This could cause of dropping one channel
3293 message. Affected file lib/silcclient/client_channel.c.
3295 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3297 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3298 lib/silcclient/client.c. This function is used when the SILC
3299 Client is run under some other scheduler, or event loop or
3300 main loop. On GUI applications, for example this may be
3301 desired to used to run the client under the GUI application's
3302 main loop. Typically the GUI application would register an
3303 idle task that calls this function multiple times in a second
3304 to quickly process the SILC specific data.
3306 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3308 * Fixed silc_server_drop() for dropping the supplementary
3309 groups as well, this could cause a security hole on some
3312 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3314 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
3317 * Write PID file after dropping privileges. Added -F option
3318 to run server on foreground. A patch by debolaz.
3319 Affected files silcd/server.c, silcd/silcd.c.
3321 * Fixed MOTD to return the MOTD file server name. Affected
3322 file silcd/command.c.
3324 * Added INFO command reply handling to the Irssi SILC Client.
3325 Affected file irssi/src/silc/core/client_ops.c.
3327 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3329 * Fixed the silc_idcache_list_* routines to really support
3330 the dynamic list. Fixes a crash. Affected file is
3331 lib/silccore/silcidcache.c.
3333 * Fixed the LIST command reply to really call LIST command's
3334 pending callbacks. Affected file silcd/command_reply.c.
3336 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3338 * Update conn->local_entry->nickname after giving NICK
3339 command. Affected file lib/silcclient/command.c.
3341 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3343 * Added the [pid] option to the silcd configuration file
3345 Affected files: serverconfig.[ch] and silcd.c
3347 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3349 * Save fingerprint in WHOIS command reply in server.
3350 Affected file silcd/command_reply.c.
3352 * Fixed NICK commands pending callback registration.
3353 Affected file lib/silcclient/command.c.
3355 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3357 * Use ++server->cmd_ident when sending commands in server,
3358 instead of random number. Affected file silcd/command.c.
3360 * Fixed GETKEY command reply to call actually GETKEY pending
3361 command callbacks. Affected file silcd/command_reply.c.
3363 * A bit stricter check for nicknames. Check for same nickname
3364 in NICK command also. Affected file silcd/command.c.
3366 * Do not call INFO command everytime client ID changes, only
3367 during first connecting. Affected file lib/silcclient/client.c.
3369 * Set the new nickname only after successful command reply for
3370 NICK command is returned by server. Affected file
3371 lib/silcclient/command.c.
3373 * Remove nicknames from nicklist during server_signoff notify.
3374 Should fix /NAMES bit more. The affected file is
3375 irssi/src/silc/core/silc-channels.c.
3377 * Added `fingerprint' field to the SilcIDListData in the
3378 silcd/idlist.h to hold the fingerprint of the client's
3381 Send the fingerprint of the client's public key in WHOIS
3384 Affected files silcd/command.c, and silcd/idlist.[ch].
3386 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3387 create fingerprint from given data.
3389 * Show the fingerprint of the client's public key in WHOIS.
3390 Affected files irssi/src/module-formats.[ch] and
3391 irssi/src/silc/core/client_ops.c.
3393 * Format the multiple same nicknames also during JOIN and
3394 NICK_CHANGE notifys. Affected file is
3395 lib/silcclient/client_notify.c.
3397 * Do not print error on screen for invalid private message
3398 payload since it can come if someone is sending private
3399 messages with wrong key. Affected file
3400 lib/silccore/silcprivate.c.
3402 * Fixed multiple concurrent /PING crash. Affected file
3403 lib/silcclient/command.c.
3405 * Changed the wrong ID encoding. All IP addresses must be
3406 in MSB first order in encoded format. They were encoded
3407 wrong and was in LSB format. Affected files are
3408 silcd/serverid.c, lib/silcutil/silcutil.c.
3410 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3412 * Call the `connect' client operation through the scheduler
3413 in case of error. Affected file lib/silcclient/client.c.
3415 * Call the `failure' client operation even if the error
3416 occurred locally during a protocol. Affected file is
3417 lib/silcclient/protocol.c.
3419 * Added support of sending LIST command to router from normal
3420 server. This way normal server can get list of all channels
3421 in the network too. Fixed the channel list sending in the
3422 server too. Affected files are silcd/command.c, and
3423 silcd/command_reply.[ch].
3425 * Added silc_server_update_channels_by_server and
3426 silc_server_remove_channels_by_server. They are used during
3427 disconnection of primary router and in backup router protocol.
3428 Affected file silcd/server_util.[ch], silcd/server.c and
3429 silcd/server_backup.c.
3431 * Fixed channel adding to global list in IDENTIFY command
3432 reply in server. Affected file silcd/command_reply.c.
3434 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3436 * If the incoming packet type is REKEY or REKEY_DONE process
3437 that packet always synchronously. Fixes yet another MAC
3438 failed error on slow (dialup) connections. Affected file
3439 lib/silcclient/client.c and silcd/server.c.
3441 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3443 * Call check_version SKE callback for initiator too. Affected
3444 file lib/silcske/silcske.c.
3446 * Implemented fix for security hole found in the SKE that was
3447 fixed in the specification few days back; the initiator's
3448 public key is now added to the HASH value computation.
3449 Added backwards support for the old way of doing it too, for
3450 old clients and old servers. Affected file is
3451 lib/silcske/silcske.c.
3453 * Enabled mutual authentication by default in SKE. If initiator
3454 is not providing mutual authentication the responder will
3455 force it. This will provide the proof of posession of the
3456 private key for responder. The affected files are
3457 lib/silcclient/protocol.c and silcd/protocol.c.
3459 * Do not cache anymore the server's public key during SKE.
3460 We do mutual authentication so the proof of posession of
3461 private key is done, and if the server is authenticated in
3462 conn auth protocol with public key we must have the public
3463 key already. Affected file silcd/protocol.c.
3465 * Added new global debug variable: silc_debug_hexdump. If
3466 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3467 file lib/silcutil/silclog.[ch].
3469 * Fixed compilation warning due to char * -> const char *.
3470 Affected files lib/silcutil/silcnet.h, and
3471 lib/silccore/silcauth.[ch].
3473 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3475 * Fixed CMODE command when new channel key was created. If
3476 the creation failed the old key was removed. Next time giving
3477 same command would crash the server since the old key was
3478 freed already. Affected file silcd/command.c.
3480 * Fixed the silc_server_announce_get_channels to not crash
3481 on reconnect. Affected file silcd/server.c.
3483 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3485 * Added silc_log_set_debug_string function to set a regex
3486 string to match for debug output. Only the function names,
3487 or filenames matching the given debug string is actually
3488 printed. This way it is possible to filter out those debug
3489 strings that user is not interested in.
3491 Fixed a bug in silc_string_regexify.
3493 Affected files lib/silcutil/silclog.[ch], and
3494 lib/silcutil/unix/silcunixutil.c.
3496 * Changed the -d options in both server and Irssi SILC client
3497 to take the debug string as argument. Affected files
3498 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3500 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3502 * Added silc_hash_babbleprint to create a Bubble Babble
3503 Encoded fingerprint. The encoding is developed by Antti
3504 Huima (draft-huima-babble-01.txt), and it creates human
3505 readable strings out of binary data. Affected file
3506 lib/silccrypt/silchash.[ch].
3508 * Print the babble print now in addition of fingerprint as well
3509 in Irssi SILC client. Affected files are
3510 irssi/src/fe-common/silc/module-formats.[ch],
3511 irssi/src/fe-common/silc/core/client_ops.c.
3513 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3515 * Fixed a security problem found in SKE. The initiator's
3516 public key too is now added to the HASH hash value creation
3517 which is signed by the responder to create the SIGN value.
3518 This will prevent anyone in the middle to lie to the responder
3519 about the initiator's public key. If this is done now, the
3520 man in the middle will get caught. Updated the protocol
3523 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3525 * Better installation directory handling. Configure module
3526 paths and other paths automatically to example_silc* files
3527 in doc/. A patch by toma.
3529 * Fixed compiler warning from MPI library, and from SILC RNG.
3532 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3533 It can be configured with ./configure. A patch by toma.
3535 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3537 * Find correct make to use in prepare-clean. A patch by
3538 toma. Affected file prepare-clean.
3540 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3542 * Added irssi variables use_auto_addr, auto_bind_ip,
3543 auto_bind_port and auto_public_ip.
3545 * Changed the interface for silc_client_send_key_agreement
3546 in lib/silcclient/silcapi.h
3550 irssi/src/silc/core/silc-core.c
3552 lib/silcclient/silcapi.h
3553 irssi/src/silc/core/silc-channels.c
3554 lib/silcclient/client_keyagr.c
3557 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3559 * Added silc_pkcs_public_key_compare to compare two
3560 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3562 * Check that the client who set the founder mode on the
3563 channel is the same client that is giving the founder
3564 mode to itself. It is done by comparing the saved public
3565 key (it is saved even in the authentication is passphrase).
3566 Affected file silcd/command.c.
3568 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3570 * Do not process packet for disconnected socket connection.
3571 Affected file lib/silccore/silcpacket.c.
3573 * Process the DISCONNECT packet through scheduler in the
3574 client library. Affected file lib/silcclient/client.c.
3576 * Fixed the silc_client_packet_parse to not to increase
3577 the packet sequence number if the conn->sock and the
3578 current socket connection is not same. This can happen
3579 for example during key agreement when the conn includes
3580 multiple socket connections (listeners). Affected file
3581 lib/silcclient/client.c.
3583 * The sender of the file transfer request now provides also
3584 the pointer (listener) for the key exchange protocol. If
3585 the listener cannot be created then it sends empty key
3586 agreement and lets the receiver provide the listener.
3588 Added `local_ip' and `local_port' arguments to the
3589 silc_client_file_send. If they are provided they are used,
3590 if not then it will attempt to find local IP address, if
3591 not found or bind fails then the remote client will provide
3594 Affected files are lib/silcclient/client_ftp.c and
3595 lib/silcclient/silcapi.h.
3597 * Extended the FILE SEND command to support defining the
3598 local IP and port for key exchange listener. They are
3599 optional. Affected file irssi/src/silc/core/silc-servers.c.
3601 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3603 * Defined to WHOIS command reply the sending of fingerprint
3604 of the client's public key (if the proof of posession of the
3605 corresponding private key is verified by the server).
3606 Updated to the protocol specification.
3608 * Added support of receiving the client's public key's
3609 fingerprint in command reply in client library. Affected
3610 file is lib/silcclient/command_reply.c, and
3611 lib/silcclient/idlist.[ch].
3613 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3615 * Do not send over 128 chars long nickname to the server
3616 in NICK command. Affected file lib/silcclient/command.c.
3618 * Do not send over 256 chars long channel names to the server
3619 in JOIN command. Affected file lib/silcclient/command.c.
3621 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3623 * Assure that silc_server_close_connection cannot be called
3624 twice for same socket context. Affected file is
3627 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3629 * Send error message to application if opening file for
3630 writing during file transfer fails. Affected file is
3631 lib/silcclient/client_ftp.c.
3633 Remove all file transfer sessions for a client that we're
3634 removing from ID cache.
3636 Affected file is lib/silcclient/client_ftp.c.
3638 * Fixed silc_net_addr2bin to return correct address. Affected
3639 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3641 * Fixed file transfer session removing on signoff notify.
3642 Affected file irssi/src/silc/core/silc-servers.c.
3644 * Added the SilcClientFileError to be returned in the monitor
3645 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3646 Affected file lib/silcclient/silcapi.h.
3648 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3650 * Fixed a crash in silc_client_ftp_free_sessions and
3651 silc_client_ftp_session_free_client. Affected file
3652 lib/silcclient/client_ftp.c.
3654 * Added `disabled' field in the SilcChannelEntry in the server
3655 to indicate if the server entry is disabled. Affected file
3656 silcd/idlist.h, silcd/command[_reply].c.
3658 * SILC server adds now /var/run/silcd.pid everytime it is
3659 started. Affected file silcd/silcd.c.
3661 * Added silc_server_packet_send_clients to send a packet to
3662 the provided table of client entries. Affected file
3663 silcd/packet_send.[ch].
3665 * Fixed a crash in client resolving in client_prvmsg.c in
3666 client library. Affected file lib/silcclient/client_prvmsg.c.
3668 * Do not actually remove the client directly from ID cache
3669 during SERVER_SIGNOFF, but invalidate it. This way we
3670 preserve the WHOWAS info for the client. Affected file
3671 silcd/server_util.c.
3673 * Fixed SERVER_SIGNOFF notify handling in the server. The
3674 server is now able to process incoming SERVER_SIGNOFF notify
3675 for a server that it doesn't even know about. It will remove
3676 the clients provided in the notify. Affected file
3677 silcd/packet_receive.c.
3679 * Check for partial packet in data queue after every packet that
3680 was found from the queue. Return and wait for more data if
3681 there is partial data in queue. Affected file is
3682 lib/silccore/silcpacket.c.
3684 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3686 * Added SilcClietFileError enum to indicate error in
3687 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT

3689 Affected files lib/silcclient/silcapi.h and
3690 lib/silcclient/client_ftp.c.
3692 * Check that newsize in silc_buffer_realloc is larger than
3693 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3695 * Added better monitor of file transfers. It now monitors
3696 key agreement protocol during the file transfer too. Added
3697 error reporting too. Affected files
3698 irssi/src/silc/core/silc-servers.c,
3699 irssi/src/fe-common/silc/module-formats.[ch].
3701 * Wrote a help file for FILE command.
3703 * Added silc_rng_global_get_byte_fast to get not-so-secure
3704 random data as fast as possible. Random data is read from
3705 /dev/urandom if available and from the SILC RNG if not
3706 available. It is used in padding generation. Affected file
3707 lib/silccrypt/silcrng.[ch].
3709 * All packets in client library are now processed synchronously.
3710 Optimized packet processing a lot. Affected file
3711 lib/silcclient/client.c.
3713 * All server connection packets are processing synchronously
3714 now in server, to optimize packet processing. Affected file
3717 * Include files are installed now only in Toolkit distribution
3718 if make install is given. Affected files: all Makefile.am's.
3720 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3722 * Assure that silc_client_notify_by_server_resolve does not
3723 resolve the client information multiple times. If it cannot
3724 be found by the first it cannot be found at all. Affected
3725 file lib/silcclient/client_notify.c.
3727 * Fixed WHOWAS command reply calling. Affected file
3728 lib/silcclient/command_reply.c.
3730 * Removed all references to silc_idlist_get_client from the
3731 Irssi SILC client since that call is internal call used by
3732 the library. The Irssi SILC client will use now client
3733 retrieval functions found in silcapi.h.
3735 * Fixed a bug in resolving nickname info before sending
3736 private message. It used freed memory. Affected file
3737 irssi/src/silc/core/silc-servers.c.
3739 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3741 * Assure my_channels statistics cannot go negative in server.
3742 Affected files silcd/server.c, silcd/server_util.c.
3744 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3758 * Added silc_net_localip to return local host's IP address.
3759 Affected file lib/silcutil/silcnet.[ch].
3761 * If key exchange or rekey protocol is active for a connection
3762 parse all packets syncronously since there might be packets
3763 in packet queue that we are not able to process without first
3764 processing packets before them. Affected file silcd/server,
3765 lib/silcclient/client.c.
3767 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3768 whether library should continue processing the packet.
3769 Affected file lib/silccore/silcpacket.h.

3800 lib/silcutil/silcutil.[ch].
3802 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3804 * Resolve the client info when received private message or
3805 channel message for a client which nickname we don't know.
3806 Affected files lib/silcclient/client_prvmsg.c and
3807 lib/silcclient/client_channel.c.
3809 * Do not crash in /KEY if client is not connected. Affected
3810 file irssi/src/silc/core/silc-channels.c.
3812 * Added SilcClientStatus field to the SilcClientEntry in the
3813 lib/silcclient/idlist.h.
3815 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3816 is incomplete and is being resolved, it won't be resolved
3819 Make sure also that USERS command reply does not resolve
3820 twice information. Affected file is
3821 lib/silcclient/command_reply.c.
3823 Make sure that silc_client_get_clients_by_list does not
3824 resolve twice same information.
3826 * Check for valid client->id in the silc_server_free_client_data.
3827 Affected file silcd/server.c.
3829 * Fixed /GETKEY nick@server not to crash if the server entry
3830 is not found. Affected file lib/silcclient/command.c.
3832 * Fixed the silc_server_check_cmode_rights to check the
3833 requested modes correctly. Affected file silcd/command.c.
3835 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3837 * Better checks for non-printable chars in nick added.
3838 Affected file silcd/command.c.
3840 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3842 * Call the silc_server_udpate_servers_by_server in the
3843 primary router that comes back online in the backup resuming
3844 protocol. Otherwise it routes packets wrong. Affected file
3845 silcd/server_util.[ch], silcd/server_backup.c.
3847 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3849 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3850 lib/silcutil/silcbuffmt.[ch].
3852 * Redefined the SILC packet header to include the padding
3853 length. Affected file lib/silccore/silcpacket.[ch].
3855 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3856 length for maximum padding up to 128 bytes). Affected
3857 file lib/silccore/silcpacket.h.
3859 * Removed all backwards support for old 0.5.x MAC thingies.
3860 The SILC packet header change makes it impossible to be
3861 backwards compatible.
3863 * Send the ENDING packet with timeout in the backup resuming
3864 protocol. This is to assure that all routers has connected
3865 to the primary router. Affected file silcd/server_backup.c.
3867 * Changed the RNG to take the first IV from random data. It
3868 used to take it from zero actually. Changed the RNG also
3869 to use /dev/urandom during session. /dev/random is used
3870 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3872 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3874 * Changed the SILC packet header to have the first two bytes
3875 (the packet length) encrypted. Affected files aroung the
3876 code tree, lib/silccore/silcpacket.[ch]. Removed the
3877 SilcPacketCheckDecrypt callback. It is not needed anymore
3878 since the silc_packet_receive_process will determine now
3879 whether the packet is normal or special.
3881 * Implemented the unidirectional MAC keys. Affected files
3882 lib/silcske/silcske.c, silcd/protocol.c and
3883 lib/silcclient/protocol.c.
3885 * Implemented the packet sequence number to the MAC computation.
3886 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3887 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3888 lib/silcclient/protocol.c.
3890 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3892 * Allow backup router to announce servers. All servers
3893 announced by backup router are added to the global list
3894 automatically. Update hte server's socket to our primary
3895 router also when backup router announces a server.
3896 Affected file silcd/packet_receive.c.
3898 * Do not update the client->router in the function
3899 silc_server_udpate_clients_by_server if the client is on
3900 global list. We might fail to find any specific server
3901 for locally connected clients and local cell clients. They
3902 should still use the `from' and not `to' as client->router.
3903 This fixes backup router resuming protocol. Affected file
3904 silcd/server_util.c.
3906 * Decrease channel statistics count only if the channel
3907 deletion worked. Affected files are silcd/server.c and
3908 silcd/server_util.c.
3910 * Added silc_server_update_servers_by_server to update origin
3911 of all server entries. Used during backup router protocol.
3912 Affected files silcd/server_util.[ch], silcd/server.c. and
3913 silcd/backup_router.c.
3915 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3916 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3917 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3918 lib/silccrypt/silchmac.c.
3920 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3922 * Assure that router cannot reroute the same channel message
3923 to the sender. Affected file silcd/packet_receive.c.
3925 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3927 * Made better checks that the channel message is not sent
3928 to the router it came from. Affected file is
3929 silcd/packet_send.c. Fixed memory leak too.
3931 * Announce informations for incoming router connection, but
3932 only after checking if it is replaced by backup router.
3933 Affected file silcd/packet_receive.c.
3935 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3937 * Fixed the backup resuming protocol to work in multiple
3938 router environment. Affected file silcd/server_backup.c.
3940 * Route packet only to one router in the function
3941 silc_server_packet_send_to_channel. Affected file is
3942 silcd/packet_send.c.
3944 * Fixed silc_server_send_notify_dest to set the broadcast
3945 flag. Fixed the silc_server_send_notify_topic to actually
3946 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3947 Affected file silcd/packet_send.c.
3949 * Changed the SFTP Filesystem interface. Changed the
3950 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3951 the filesystem operation function. The SilcSFTPFilesystem
3952 is now a context that is allocated by all filesystem allocation
3953 functions and it already includes the operations structure
3954 and filesystem specific context. It is given as argument
3955 now to the silc_sftp_server_start. This made the interface
3956 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3957 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3959 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3961 * Changed the backup router adding and getting interfaces
3962 in the server. The router that will be replaced by the
3963 specified backup router is now sent as argument. Affected
3964 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3967 * Added silc_net_addr2bin_ne to return the binary form of
3968 the IP address in network byte order. Affected files
3969 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3971 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3973 * Check for existing server ID in silc_server_new_server
3974 and in silc_server_connect_to_router_final and remove the
3975 old entry if it exists. Affected file silcd/packet_receive.c,
3978 * Send the channel message always to only one router, either
3979 in upstream or downstream. Affected file is
3980 silcd/packet_send.c.
3982 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3984 * Wrote the definition of the backup resuming protocol to the
3985 protocol specification.
3987 * Removed one redundant channel key generation from normal
3988 server during joining procedure. Removed one redundant
3989 channel key sending from server to router during joining
3990 procedure. Affected file silcd/command.c.
3992 * Made minor bugfixes to the backup router resuming protocol.
3993 Affected file silcd/server_backup.c, server.c.
3995 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3997 * Added --disable-asm configuration option. Affected files
3998 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
4001 * Implemented the backup resuming protocol that is used to
4002 resume the primary router position in the cell after the
4003 primary router comes back online. Affected files
4004 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
4005 and silcd/server_util.[ch].
4007 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4009 * Sleep two (2) seconds after sending QUIT command to server.
4010 Affected file lib/silcclient/command.c.
4012 * Assure that if outgoing data buffer is pending do not force
4013 send any data. Affected file silcd/packet_send.c.
4015 * Assure that if outgoing data buffer is pending do not force
4016 send any data. Affected file lib/silcclient/client.c.
4018 * Implemented the backup router support when the primary router
4019 goes down. The servers and routers can now use the backup
4020 router as new primary router without loosing connectivity.
4022 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4024 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
4025 in the server to indicate disabled entry. All data read
4026 from the connection will be ignored and no data is sent
4027 for entry that is disabled. Affected files are
4028 silcd/idlist.h, silcd/server.c.
4030 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4032 * Created SFTP client and server test programs in the
4033 lib/silcsftp/tests directory.
4035 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4037 * Implemented memory filesystem (virtual filesystem) for
4038 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
4041 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4043 * Implemented the SFTP (SSH File Transfer Protocol) to the
4044 lib/silcsftp. It includes SFTP client and SFTP server
4047 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4049 * Moved lib/silccore/silcprotocol.[ch] to the
4050 lib/silcutil library.
4052 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
4053 take variable argument list pointer as argument. Affected
4054 file lib/silcutil/silcbuffmt.[ch].
4056 * Added silc_buffer_set function that is used to set data
4057 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
4058 Affected file lib/silcutil/silcbuffer.h.
4060 * Changed various routines in the core library to use the new
4061 silc_buffer_set instead of allocating new buffer only for
4064 * Added 64-bit value formatting and unformatting support to the
4065 silc_buffer_[un]format routines. Affected file is
4066 lib/silcutil/silcbuffmt.[ch].
4068 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
4069 to includes/bitmove.h.
4071 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4073 * Fixed channel user mode saving in client library. Affected
4074 file lib/silcclient/command[_reply].c.
4076 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4078 * Defined the file transfer to the SILC Protocol. Added
4079 new packet type SILC_PACKET_FTP and defined File Transfer
4080 Payload. The mandatory file transfer protocol is SFTP
4081 (SSH File Transfer Protocol). Affected file in addition
4082 of the internet draft is lib/silccore/silcpacket.h.
4084 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
4085 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
4086 is used as part of backup router protocol when the primary
4087 router of the cell is back online and wishes to resume
4088 the position as primary router.
4090 * Redefined the MAC generation keys in the protocol. The
4091 same key is not used anymore in both direction. Both
4092 direction will now use different keys for sending and
4093 receiving. This fixes a potential security flaw. This
4094 change causes incompatibilities in the protocol.
4096 * Redefined also the MAC computation from the packet.
4097 An packet sequence number is now added to the MAC
4098 computation. This prevents possible replay attacks against
4099 the protocol. This change too causes incompatibilities
4102 Added `sequence' field to the SilcPacketContext to hold
4103 the current sequence number for the packet.
4105 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4107 * Added `created' field to the SilcIDListData in the file
4108 silcd/idlist.h to indicate the time when the entry was
4111 * Added `created' field to the SilcChannelEntry too. Affected
4112 file silcd/idlist.h.
4114 * Added `creation_time' aguments to all the announcement functions
4115 in the server. If it is provided then only the entries that
4116 was created after the provided time frame are actually
4117 announced. Affected file silcd/server.[ch].
4119 * The protocol says that the Channel ID's IP address must be
4120 based on the router's IP address. Added check for this in
4121 the silc_server_new_channel when processing incoming New Channel
4122 Payload. Affected file silcd/packet_receive.c.
4124 * Print out the correct version with --version in SILC client.
4125 Affected file irssi/src/silc/core/silc-core.c.
4127 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4129 * Fixed WHOWAS command to check for completnes of the client
4130 entry always, not just when the command is coming from client.
4131 Affected file silcd/command.c.
4133 * Added new function silc_server_packet_queue_purge to purge the
4134 outgoing data queue to the network. After the function returns
4135 it is guaranteed that the outgoing packet queue is empty.
4136 Affected file silcd/packet_send.[ch].
4138 * Purge the outgoing packet queue in the rekey protocol's final
4139 callback to assure that all rekey packets go to the network
4140 before quitting the protocol. Affected file silcd/server.c.
4142 * Added silc_client_packet_queue_parse as similar function as
4143 in server to the client library. The affected file is
4144 lib/silcclient/client.c.
4146 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4148 * Splitted silcd/server.c and created silcd/server_util.[ch]
4149 for utility functions.
4151 * Added new socket flag SILC_SF_DISABLED to indicate that the
4152 connection is open but nothing can be sent to or received from
4153 the connection. Affected file lib/silcutil/silsockconn.[ch].
4154 The checking for disabled socket is checked in the low level
4155 silc_socket_write and silc_socket_read functions.
4157 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4159 * Allow only nicknames and channel names that fits into the
4160 7-bit unsigned char ASCII set. Affected file silcd/command.c.
4162 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4164 * When processing JOIN command reply in server check that if
4165 the channel exists in our global list we'll move it the local
4166 list. Affected file silcd/command_reply.c.
4168 * Fixed the check whether client is joined on the channel already
4169 in JOIN command. Affected file lib/silcclient/command.c.
4171 * Fixed the JOIN command reply to check whether the channel
4172 already exists. Affected file lib/silcclient/command_reply.c.
4174 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4176 * Added silc_ske_status_string to map the SKE error numbers
4177 to readable strings. The affected files are
4178 lib/silcske/silcske[_status].[ch].
4180 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4182 * Do not show the private channels on the WHOIS channel list
4183 as it is not allowed by the protocol. The affected file is
4186 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4188 * Assure that the packet length digged from the actual packet
4189 is something sensible in the silc_packet_decrypt_rest_special
4190 in lib/silccrypt/silcpacket.c.
4192 * Free and NULL the allocated pointer in silc_hmac_alloc if
4193 the HMAC allocation fails. The affected file is
4194 lib/silccrypt/silchmac.c.
4196 * Print the selected security properties to the log files in
4197 the server. Affected file silcd/protocol.c.
4199 * Add SKE's reference counter even if calling the completion
4200 callback manually. Otherwise it goes negative, although it
4201 does not cause any problems. The affected file is
4202 lib/silcske/silcske.c.
4204 * Remove the client entry with short timeout after giving the
4205 KILL command. Affected file lib/silcclient/command.c.
4207 * Fixed to send error reply in WHOIS and IDENTIFY commands in
4208 case all found clients are already disconnected (WHOWAS would
4209 found them) in the server. Affected file silcd/command.c.
4211 * Update the last_receive (time of last data received) to be
4212 updated only when received private or channel message so that
4213 the idle time showed in WHOIS makes more sense.
4215 * Added boolean field `valid' in to the SilcClientEntry in the
4216 client library to indicate whether the entry is valid or not.
4217 This fixes the nickname change bug on channel when changing
4218 the nickname to be same than the old (like nick to Nick) the
4219 nickname formatter doesn't set the new nick anymore to Nick@host.
4220 Affected file lib/silcclient/idlist.[ch].
4222 * Now actually fixed the nickname changing on disconnection.
4223 Added new function silc_change_nick to the Irssi SILC Client.
4224 Affected file irssi/src/silc/core/client_ops.c,
4225 irssi/src/silc/core/silc-nicklist.[ch].
4227 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4229 * Check that the public key exists in the GETKEY command before
4230 trying to encode it. Affected file silcd/command.c.
4232 * Print some notifications on received public keys with GETKEY
4233 command in the Irssi SILC Client. Affected files are
4234 irssi/src/fe-common/silc/module-formats.[ch],
4235 irssi/src/silc/core/client_ops.c.
4237 * Use IDENTIFY command to resolve the server information in the
4238 GETKEY command instead of INFO command. Affected file
4239 lib/silcclient/command.c.
4241 * All command reply functions in the client library now calls
4242 the pending command reply callbacks even if an error has
4243 occurred. The server has done this a long time and now it was
4244 time to move the client library to this as well. Now all
4245 errors can be delivered back to the pending command reply
4246 callbacks if necessary. Affected files are
4247 lib/silcclient/command[_reply].[ch].
4249 * Change the nickname on disconnection back to the username
4250 because in reconnect the server will enforce it to it anyway.
4251 Affected file irssi/src/silc/core/silc-servers.c.
4253 * Fixed a config file parsing bug in the Irssi SILC client.
4254 Affected file irssi/src/silc/core/clientconfig.c.
4256 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4258 * When printing the channel mode on JOIN, verify that the
4259 channel key and channel's HMAC are valid. Affected file
4260 irssi/src/silc/core/client_ops.c.
4262 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4264 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
4265 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
4266 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
4268 * Removed channel key rekey task deleting from the function
4269 silc_server_save_channel_key. Affected file silcd/server.c.
4270 Added explicit timeout task context instead that is used to
4271 delete the task if we are registering a new task before the
4272 new task has elapsed.
4274 * When channel key rekey occurs the client library now saves
4275 the old channel key for a short period of time (10 seconds) and
4276 is able to use it in case some is still sending channel
4277 messages encrypted with the old key after the rekey. Affected
4278 file lib/silcclient/[idlist.h|client_channel.c].
4280 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4282 * Added check to the silc_server_new_id_real to not accept
4283 new ID if it is the sender's own ID. Affected file is
4284 silcd/packet_receive.c.
4286 * Assure that we do not announce ourself or the one we've
4287 sending our announcements when we're router and are announcing
4288 servers to our primary router. Affected file silcd/server.c.
4290 * Fixed silc_server_command_identify_check_client to assemble
4291 correct WHOIS packet. It send corrupted WHOIS packet and
4292 caused problem with router to router connections. Affected
4293 file silcd/command.c.
4295 Fixed also silc_server_command_whois_check the same way
4296 as for the IDENTIFY command.
4298 * Added new SilcIDListStatus to the server in the SilcIDListData
4299 structure. The status now includes the current status of
4300 the entry (like registered, resolved etc.). Affected file
4301 silcd/idlist.[ch]. Defined a bunch of different status types
4302 as well. This replaced the old boolean registered field as well.
4304 Added resolve_cmd_ident field to the SilcClientEntry structure
4305 too so that if the entry is for example being resolved so
4306 another command may attach to the same pending command reply
4307 without requiring to resolve the same entry again. This concept
4308 should optimize the WHOIS and the IDENTIFY resolving under
4309 heavy load by taking away unnecessary resolving for entries
4310 that are being resolved already.
4312 Added support for adding multiple pending commands for one
4313 command idenfier. Affected file silcd/command[_reply].[ch].
4315 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4316 before deleting the data. Otherwise the hash table will have
4317 freed data in comparison functions. Affected file is
4318 silcd/command_reply.c.
4320 * Fixed silc_idlist_replace_client_id to add the new entry to
4321 the cache with NULL nickname. Otherwise there will be invalid
4322 memory as the nickname after the nickname is freed. Affected
4323 file silcd/packet_receive.c.
4325 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4326 saved into wrong slots because the previous number of entries
4327 was not taken into account. Affected file silcd/idlist.c.
4328 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4330 * If we are router and we receive JOIN notify to a channel that
4331 does not have any users then notified client is marked as the
4332 channel founder, as it is it. The affected file is
4333 silcd/packet_receive.c
4335 * Added to the extended hash table API's table_del_*ext functions
4336 the destructor as argument too, so that the caller can decide
4337 which destructor to use or whether to use destructor at all.
4338 Affected file lib/silcutil/silchashtable.[ch].
4340 * Fixed ID Cache purging. It actually deleted the entries from
4341 the hash table after the data was freed. The hash table ended
4342 up comparing freed memory. The affected file is
4343 lib/silccore/silcidcache.c.
4345 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4347 * Fixed Irssi SILC client's KILL command's HELP syntax.
4349 * The USERS command now resolves the detailed user information
4350 if the userinfo field is missing. Affected file is
4351 lib/silcclient/command_reply.c.
4353 * Do not print error in silc_file_read if the read file does
4354 not exist. Just silently return NULL. Affected file is
4355 lib/silcutil/silcutil.c.
4357 * Fixed the silc_log_output to not wine about NULL filename
4358 and to not create some bogus " " filename. Affected file is
4359 lib/silcutil/silclog.c.
4361 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4363 * Fixed various printing bugs on the user interface in the
4364 Irssi SILC Client. Minor changes that were forgotten from
4367 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4369 * Fixed the configure.in.pre and the compilation and distribution
4370 environment to support the new autoconf 2.52. That version is
4371 now required to compile the CVS trunk.
4373 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4375 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4376 to generally parse user@fqdn format strings. Affected file
4377 lib/silcutil/silcutil.c.
4379 * Added nickname_format and nickname_force_format fields to the
4380 SilcClientParams structure. The first one defines the format
4381 for the nicknames that the library will enforce if the receives
4382 multiple same nicknames. The second one is boolean value and
4383 can be used to force the library to always enforce the format
4384 to the nicknames regardles whether there are multiple nicknames
4385 or not. This configurable formatting was employed to flexibly
4386 support accessing multiple nicknames from the user interface.
4387 The userinterface can now set the nicknames to what ever format
4388 they prefer. Affected file lib/silcclient/silcapi.h.
4390 Added function silc_client_nickname_format to the file
4391 lib/silcclient/idlist.c. It performs the nickname formatting.
4393 Added new field `hostname´ to the SilcClientEntry context.
4394 It holds the hostname of the client. Affected file is
4395 lib/silcclient/idlist.h.
4397 * Irssi SILC Client sets the nicknames in nick@hostn format.
4398 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4399 irssi/src/silc/core/silc-core.c.
4401 The WHOIS printing now also shows both the real nickname and
4402 the formatted nickname so that user knows how to access the
4403 user if there are multiple same nicknames cached. Affected
4404 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4405 printing formatting too to take the hostname now as a separate
4406 argument. The Affected file is
4407 irssi/src/fe-common/silc/modules-formats.[ch].
4409 * Changed the silc_client_get_clients_local to accept the formatted
4410 nickname as argument. It accepts the real nickname too but the
4411 formatted nickname can be used to find the true entry from
4412 multiple entries. Affected file lib/silcclient/silcapi.h and
4413 lib/silcclient/idlist.c.
4415 * Added nickname_format_parse field to the SilcClientParams.
4416 It is a callback function provided by the application to parse
4417 the nickname out of the formatted nickname string. The library
4418 calls it to get the nickname from the formatted string. Since
4419 the application generally knows better the format of the nickname
4420 string it parses it instead of the library, even though library
4421 encodes the formatted string. If the callback function is not
4422 provided then the library will use the string as is. The
4423 affected file is lib/silcclient/silcapi.h.
4425 * All the nickname strings passed to the client library in
4426 commands are now expected to be formatted nickname strings.
4427 If the command does not support the formatted nickname string
4428 it will assume that the sent string is the actual nickname.
4429 Affected file lib/silcclient/command.c.
4431 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4433 * Added public key authentication support to OPER and SILCOPER
4434 commands in the client library. Affected file is
4435 lib/silcclient/command.c.
4437 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4439 * Changed the get_auth_methdod client operation to be asynchronous.
4440 It can be async if the application resolves the authentication
4441 method from the server during the negotiation. Added new
4442 SilcGetAuthMeth completion callback that the application will
4443 call after resolving the authentication method.
4445 Added function silc_client_request_authentication_method that
4446 the application can use to resolve the authentication method
4447 from the server. Added also SilcConnectionAuthRequest callback
4448 that the library will call after the server has replied. The
4449 application can call this function if it does not know the
4450 current authentication method.
4452 Affected files are lib/silcclient/client.c and
4453 lib/silcclient/silcapi.h.
4455 * The Irssi SILC client now automatically resolves the authentication
4456 method incase any configuration information is not present (and
4457 currently there never is). The affected file is
4458 irssi/src/silc/core/client_ops.c.
4460 * Fixed public key authentication from the client library.
4461 Affected file lib/silcclient/protocol.c. Changed also the
4462 protocol specification about the public key authentication in
4463 the connection authentication protocol. The actual data to be
4464 signed is now computed with a hash function before signing.
4466 * Fixed the public key authentication from the server as well.
4467 Affected file silcd/protocol.c.
4469 * Removed the mlock()'s from the memory allocation routines.
4470 Affected file lib/silcutil/silcmemory.c. The ./configure does
4471 not check anymore for the mlock(). Affected file is
4474 * Fixed USERS command in server to allow the execution of the
4475 command for private and secret channels if the client sending
4476 the command is on the channel. Affected file silcd/command.c.
4478 * Fixed silc_client_get_clients_local to return the clients
4479 count correctly. It could return wrong value. Affected file
4480 lib/silcclient/idlist.c.
4482 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4484 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4485 types. The assembler optimizations seemed not to like 64-bit
4486 data types. The assmebler optimizations thus are now enabled
4487 also for BSD systems as opposed to only enable them for Linux.
4489 * Do not check for threads at all on BSD systems. Affected
4490 file configure.in.pre.
4492 * Removed -n and -h options from the Irssi SILC Client since
4493 they are not used in silc.
4495 * Fixed the prime generation to assure that the first digit
4496 of the generated random number is not zero since our conversion
4497 routines does not like number strings that starts with zero
4498 digit. If zero digit is seen the random number is regenerated.
4499 This caused some corrupted RSA keys when the zero first digit
4500 was met. Affected file lib/silcmath/silcprimegen.c.
4502 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4504 * Fixed WIN32 configuration in the ./configure script.
4505 Fixed to include xti.h on environments that has it.
4506 Patches by Carsten Ilchmann and andrew.
4508 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4510 * Changed the silc_id_create_client_id to be collision
4511 resistant. It is now assured that there cannot be created
4512 two same client ID's. I suspect that some weird bugs in
4513 the server were actually caused by duplicate Client IDs.
4514 Affected file silcd/serverid.[ch]. A router receiving
4515 new ID now also assures and informs the sending server
4516 if the ID caused collision.
4518 * Changed the silc_id_create_channel_id to also assure that
4519 there are no collisions.
4521 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4523 * Statement about ignoring the Mutual Authentication flag when
4524 performing rekey with PFS was a bit misleading. It is ignored
4525 if it was set in the initial negotiation, it cannot be even
4526 set in the rekey. Fixed in the ke-auth draft. Started the
4527 new versions of the protocol drafts in the doc/.
4529 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4531 * Fixed a bug in silc_client_command_identify_save when saving
4532 new channel information. The channel name was no duplicated
4533 and caused crash on exit. Affected file is
4534 lib/silcclient/command_reply.c.
4536 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4538 * Fixed the getkey command handling in the server. Send just
4539 empty OK reply to the sender if the key could not be fetched
4540 (but everything else was ok, like the key just was not available).
4541 Changed the public key parameter to optional in the protocol
4542 specs so that empty OK reply can be sent. Affected file
4545 Added a message to Irssi SILC client to tell to user if the
4546 server did not return a public key.
4548 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4550 * Fixed a channel key regeneration bug. It registered new
4551 timeout tasks exponentially until all system resources were
4552 used. Affected file silcd/server.c.
4554 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4556 * Added the SILC Document generator to the scripts/silcdoc.
4557 It can be used to generate the Toolkit Reference Manual out
4558 of the source tree. Internally it will also use the RoboDoc
4559 generator now imported in util/robodoc.
4561 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4563 * Added couple of return's in rekey protocol if error orccurred
4564 during the protocol. The execution must be terminated.
4565 Affected file silcd/protocol.c. Also, terminate the protocol
4566 always with timeout.
4568 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4570 * The client's Client ID was created initally from the wrong
4571 nickname (it could have been in format nick@host) in the
4572 silc_server_new_client. Affected file silcd/packet_receive.c
4574 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4576 * Added some SILC_LOG_ERROR's to various error conditions
4577 if client could not be added to ID cache. Affected files
4578 silcd/packet_receive.c and silcd/server.c.
4580 * When client's sock->user_data is freed, NULL also the
4581 client->router and client->connection pointers. Added check
4582 for these pointers being NULL to various places around the
4583 code. Affected file silcd/server.c.
4585 * Added client->data.registered == TRUE checks to various
4586 places around the code to assure that unregistered client's
4587 are not handled when it is not allowed. Affected file
4590 * Added `bool registered' fields to all
4591 silc_idlist_[server|client]_get_* routines to indicate whether
4592 the fetched client needs to be registered or not. Affected
4593 file silcd/idlist.[ch].
4595 * Add your own entry as registered to the ID cache in the
4596 server. Affected file server.c.
4598 * Fixed a bug in silc_server_new_server. The SilcServer was
4599 set as the new server's context instead of SilcServerEntry.
4600 This naturally caused some weird bugs.
4602 * Added "updated" field the SilcChannelEntry which indicates
4603 the time since the channel entry was last accessed. This
4604 can be used to determine whether it is necessary to
4605 announce the channel after backup resuming protocol.
4606 Affected files silcd/idlist.[ch].
4608 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4610 * Do not delete the channel rekey task when adding it
4611 for in silc_server_create_channel_key.
4613 * Changed the silc_server_create_channel_key to return
4614 TRUE or FALSE to indicate the success of the channel key
4617 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4619 * Fixed MSVC++ project files and added missing files to
4620 Makefiles under win32/.
4622 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4624 * Do not add TCP_NODELAY flag if the operating system
4625 does not have it defined. Affected files are
4626 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4628 * Fixed buffer overflow from Irssi SILC Client. Affected
4629 file irssi/src/fe-common/core/themes.c.
4631 * Fixed double free in client library in the file
4632 lib/silcclient/client.c when disconnecting from server.
4634 * Applied double free patch from cras to Irssi SILC client.
4635 Affected files irssi/src/core/[modules/expandos].c
4637 * Fixed the disconnection handling to Irssi SILC Client.
4638 The application must call silc_client_close_connection
4639 in ops->connect client operation in case of failure of
4640 the connection. Affected file is
4641 irssi/src/silc/core/client_ops.c.
4643 * Do not set sock->protocol to NULL in the function
4644 silc_client_close_connection after executing the protocol's
4645 final callback since the sock might not be valid anymore.
4646 Affected file lib/silcclient/client.c.
4648 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4650 * Do not enable SILC_THREADS if the linking with libpthread
4651 did not happen. Affected file configure.in.pre.
4653 * Added notion to protocol specification that server must
4654 verify the sent authentication payload with CMODE when
4655 setting the channel founder key. Implemented it to the
4656 server. Affected file silcd/command.c.
4658 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4660 * Added _EXTRA_DIST SILC distribution variable to the
4661 distributions file. It is used to conditionally add extra
4662 files or directories to the specific distribution. Affected
4663 files ./prepare, Makefile.am.pre and distributions.
4665 Removed the `_' from the start of the distribution names.
4668 * Added README.WIN32 for instructions to compile the Toolkit
4671 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4673 * Fixed a double free in disconnection in the server. Affected
4674 file is silcd/server.c.
4676 * Fixed the lib/silcske/groups.c to work now also with GMP
4677 MP library. The string conversion did not work when using
4678 specific base and the base is indicated in the string as well.
4680 * Created win32/ directory which now includes MSVC++ specific
4681 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4682 It will appear only in the toolkit distribution
4684 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4686 * Changed the key material distribution function in case when
4687 the hash output is too short. The data is now concatenated
4688 a bit differently than it used to. Made the change to the
4689 SKE protocol specification.
4691 * Added better GMP detection to configure.in.pre. A patch
4694 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4696 * Fixed a minor bug in SKE that might cause some problem on
4697 some platforms. Affected file lib/silcske/silcske.c.
4699 * Added the cookie checking for initiator in the SKE. It checks
4700 that the responder returns the sent cookie unmodified. The
4701 affected file is lib/silcske/silcske.c. Added new SKE
4702 error type INVALID_COOKIE that can be sent during the
4703 negotiation. Fixed some memory leaks as well.
4705 * Added the "invalid cookie" error message to Irssi SILC client's
4708 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4710 * Added `task_max' field to the SilcClientParams to indicate
4711 the maximum tasks the scheduler can handle. If set to zero,
4712 default values are used. Affected file lib/silcclient/silcapi.h.
4714 * Fixed memory leaks in silc_client_close_connection. Affected
4715 file lib/silcclient/client.c.
4717 * Added silc_client_del_client_entry to client library to free
4718 all memory of given client entry. Affected file is
4719 lib/silcclient/idlist.[ch].
4721 * Added new functions silc_client_del_channel and
4722 silc_client_del_server to delete channel and server entries.
4723 Affected file lib/silcclient/[silcapi.h/idlist.c].
4725 * Removed silc_client_del_client_by_id from silcapi.h.
4727 * Fixed the INFO command to return the server's own info
4728 correctly when querying by Server ID. Affected file is
4731 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4733 * Removed the non-blocking settings in WIN32 code in the
4734 silc_sock_[read/write] and added SleepEx instead. Affected
4735 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4736 of input data is now checked with FIONREAD and ioctlsocket.
4738 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4740 * Call silc_schedule_task_del_by_context in the
4741 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4742 Affected file lib/silccore/silcprotocol.c.
4744 * Call silc_protocol_cancel for active protocols in the
4745 silc_server_close_connection if the funtion
4746 silc_server_free_sock_user_data has not been called.
4747 Affected file silcd/server.c.
4749 * Generic tasks cannot be deleted using the del_by_fd
4750 task deleting function since generic tasks does not match
4751 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4753 * Added a notion to SILCOPER help file that the SILCOPER works
4754 only on router server, not on normal server.
4756 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4758 * Added for WIN32 support for the new scheduler as well.
4759 Affected file lib/silcutil/win32/silcwin32schedule.c.
4761 * Fixed the SHA1 implementation to work on various platforms.
4763 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4765 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4766 API. It is part of the scheduler now. Everything else is
4767 as previously but some functions has changed their names.
4768 Checkout the lib/silcutil/silcschedule.h for the interface.
4769 Updated all applications to use the new interface. Affected
4770 files are lib/silcutil/silcschedule.[ch].
4772 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4774 * Found a bug in the SKE implementation. The HASH value,
4775 specified by the protocol, was not computed correctly. The
4776 public key of the responder was not added to the computation
4777 even though it is mandatory. Affected file lib/silcske/silcske.c.
4778 This unfortunately causes incompatibilities with older
4779 clients and servers.
4781 * Added WIN32 specific network init and uninit functions:
4782 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4783 the Winsock2. Affected file lib/silcutil/silcnet.h and
4784 lib/silcutil/win32/silcwin32net.c.
4786 * Set the socket always to nonblocking mode on WIN32 after
4787 reading data or writing data. Affected file is
4788 lib/silcutil/win32/silcwin32sockconn.c.
4790 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4792 * Fixed various compilation problems under WIN32. Affected
4793 files lib/silcutil/win32/silcwin32thread.c and
4794 lib/silcutil/win32/silcwin32schedule.c.
4796 * Removed all _internal.h #includes from public header
4797 files. Internal headers must never be included from
4800 Removed also the lib/silcske/payload_internal.h file.
4802 * All include files that may be needed (public and some others
4803 included by the public headers) by application developers are
4804 now copied to the ./includes directory. It does not copy any
4805 internal headers. Affected file Makefile.defines.pre and all
4806 Makefile.am's under lib/ and subdirs.
4808 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4810 * Do not change the ~/.silc directory's permissions automatically.
4811 Affected file irssi/src/silc/core/clientutil.c.
4813 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4815 * Do not cancel the protocol in silc_server_close_connection
4816 it might cause recursion. Now cancelled in the function
4817 silc_server_free_sock_user_data. Affected file silcd/server.c.
4819 * Fixed the silc_server_remove_clients_by_server to regenerate
4820 the channel keys correctly finally. Added also new function
4821 silc_server_remove_clients_channels to actually do it.
4822 Affected file silcd/server.c.
4824 * Fixed the silc_server_new_channel to not crash by giving
4825 wrong router to the new channel. Affected file is
4826 silcd/packet_receive.c.
4828 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4830 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4831 which is given as argument to the silc_client_alloc now.
4832 It can be used to configure the client and set various parameters
4833 that affect the function of the client.
4835 * The USERS command in server did not check whether the channel
4836 is private or secret. Affected file silcd/command.c.
4838 * Added new argument to the USERS command in protocol specification.
4839 The USERS command now can take the channel name as argument
4840 as well. Added support for this in client and server and
4841 updated the protocol specs.
4843 * Completed the GETKEY command in client. It can be now used
4844 to fetch also servers public key not only some clients.
4845 Affected files lib/silcclient/command[_reply].c.
4847 * Added silc_client_get_server to return server entry by the
4848 server name. Affected files lib/silcclient/silcapi.h and
4851 * Redefined the IDENTIFY command in protocol specification to be
4852 more generic. It now can be used to query information about
4853 any entity in the SILC Network, including clients, servers and
4854 channels. The query may be based either the entity's name
4855 or the ID. Added support for this in both client and server.
4857 Affected files silcd/command.c and lib/silcclient/command.c
4858 and command_reply.c.
4860 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4861 the _from_client and _from_server functions. Affected file
4864 * Added silc_client_get_channel_by_id_resolve to the file
4865 lib/silcclient/silcapi.h to resolve channel information by
4866 its ID. Added also silc_client_get_channel_by_id that
4867 does not resolve it from the server.
4869 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4871 * Added SilcServerEntry context into the client library
4872 to represent one server. The INFO command now allocates
4873 these to save the resolved server info. For now on the
4874 client library will also keep information about servers,
4875 connected and resolved with INFO.
4877 The INFO command now allocates the SilcServerEntry context
4878 and saves the server info there. The COMMAND_REPLY in
4879 the INFO now returns the parameters to application in
4880 same order as defined in the protocol specification.
4882 The entries are cached in the client->server_cache.
4884 * The INFO command is now issued after received the Client ID
4885 from the server. Affected file lib/silcclient/client.c.
4887 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4888 to the application as the mode changer might be server.
4889 It is guaranteed that NULL is not returned anymore to the
4890 application. Affected file lib/silcclient/client_notify.c.
4892 The ID Type is now also passed to the application so that
4893 it can check whether the returned entry is SilcClientEntry
4896 Added new function silc_client_get_server_by_id to return
4897 the server entry by ID. Affected files are the
4898 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4900 * Do not create the channel in the Irssi SILC Client when issuing
4901 the JOIN command but when received the sucessful JOIN command
4902 reply. Otherwise the channel might get created even though we
4903 could not join it. The Affected file is
4904 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4906 * Fixed a channel joining bug in router. The router must also
4907 check the channel modes, invite and ban lists etc. when serving
4908 the JOIN command sent by normal server. Affected file is
4909 silcd/command.c. The router now resolves the client's
4910 information from the server who sent the JOIN command if it
4911 does not know it, and processes the JOIN command only after
4914 * Changed the SilcCommandCb to take new argument; void *context2.
4915 Affected file lib/silccore/silccommand.h
4917 The second argument in the command callbacks in the server now
4918 includes the SilcServerCommandReplyContext if the command was
4919 called as pending command callback from the command reply.
4920 Otherwise it is NULL. When called as pending the status of the
4921 command reply will be checked and if it was erronous the
4922 error will be sent to the original sender of the command.
4923 This way the client always receives the error messages even
4924 though the server was actually the one who received the error
4925 when it resent the command to router, for example. Affected
4926 files silcd/command[_reply].[ch].
4928 * Fixed sending WHOWAS command's error message to client if
4929 the requested client could not be found. It was missing.
4932 * Changed the CMODE and CUMODE commands reply arguments in the
4933 protocol specification. The Channel ID is now sent in both
4934 of the commands to identify the channel. Implemented this
4935 new feature to the client and server. Affected files
4936 lib/silcclient/command_reply.c and silcd/command.c.
4938 * Made better checks for invite and ban lists in the JOIN
4939 command in server. Affected file silcd/command.c.
4941 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4943 * The server now performs the incoming host IP/DNS lookup
4944 using the silc_socket_host_lookup and thus does not block
4945 the server anymore. Affected file silcd/server.c.
4947 * Completed the multi-thread support for SILC Scheduler in
4948 the lib/silcutil/silcschedule.c.
4950 * Fixed the configure.in.pre to detect the pthread correctly
4953 * Fixed a deadlock in silc_task_queue_wakeup in the file
4954 lib/silcutil/silctask.c.
4956 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4958 * Added new function silc_schedule_wakeup that is used in
4959 multi-threaded environment to wakeup the main thread's
4960 schduler. It needs to be used when a thread adds a new task
4961 or removes a task from task queues. After waking up, the
4962 scheduler will detect the task queue changes. If threads
4963 support is not compiled in this function has no effect.
4964 Implemented the wakeup mechanism to both Unix and WIN32
4965 systems. Affected files are lib/silcutil/silcschedule.[ch],
4966 lib/silcutil/unix/silcunixschedule.c and the
4967 lib/silcutil/win32/silcwin32schedule.c.
4969 * Added new function silc_task_queue_wakeup to wakeup the
4970 scheduler by the specified task queue. Affected file
4971 lib/silcutil/silctask.[ch].
4973 * The silc_socket_host_lookup_start now wakes up the scheduler
4974 after adding the timeout task. Affected file is
4975 lib/silcutil/silcsockconn.c.
4977 * The silc_socket_host_lookup is synchronous now if the threads
4978 support is not compiled in. However, the callback is still
4979 called asyncronously through the scheduler, anyway. Affected
4980 file lib/silcutil/silcsockconn.c.
4982 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4984 * Added new function silc_socket_host_lookup to perform
4985 asynchronous IP and FQDN lookups for the socket connection.
4986 Affected files lib/silcutil/silcsockconn.[ch].
4988 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4990 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4991 that may or may not compile the mutex support in.
4993 Changed the silc_mutex_alloc interface. It allocates the
4994 mutex now to the sent pointer and returns TRUE or FALSE.
4996 Affected file lib/silcutil/silcmutex.h.
4998 * Wrote the SILC Task Queue interface to support multi-threads.
4999 Affected file lib/silcutil/silctask.[ch].
5001 * Wrote the SILC Scheduler to support multi-threads. Affected
5002 file lib/silcutil/silcschedule.c.
5004 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5006 * Implemented the SILC Mutex API and SILC Thread API for WIN32
5007 in lib/silcutil/win32/.
5009 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5011 * Defined SILC Mutex API and SILC Thread API and implemented
5012 them for Unix. Affected files are
5013 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
5014 lib/silcutil/unix/silcunixmutex.c and
5015 lib/silcutil/unix/silcunixthread.c.
5017 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5019 * Fixed the silc_server_remove_clients_by_server's channel
5020 key re-generation. The hash table handling was incorrect
5021 and would not work with many channels. Affected file is
5024 * Fixed some memory leaks around the server code.
5026 * Rewrote the silc_server_get_users_on_channel to support IPv6
5027 based Client ID's. Affected file silcd/server.c.
5029 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
5030 specification. However, a separate document must be written
5031 to define the detailed signing procedure and the payload
5032 associated with the flag. Defined the flag to the
5033 lib/silccore/silcchannel.h as well.
5035 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5037 * Changed the dynamic tables to static size tables in the
5038 lib/silccrypt/silchmac.c.
5040 * Removed GCC dependencies from the code. A patch by cras.
5042 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5044 * Do not show the error "Error receiving packet bla bla"
5045 in server if it really was not an error (-2 means that reading
5046 is pending). Affected file silcd/server.c.
5048 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5050 * Fixed a possible crash in silc_server_remove_clients_by_server
5051 in silcd/server.c. Fixed there also some memory leaks.
5053 * Fixed the silc_idlist_replace_client_id. It could replace
5054 wrong key in the hash table. Affected file silcd/idlist.c.
5056 * Do not check whether there are global users on the channel
5057 if the channel->global_users is FALSE. Affected functions
5058 silc_server_remove_from_one_channel and
5059 silc_server_remove_from_channels in silcd/server.c. Also,
5060 do not check if the removed client is local as we can be
5061 sure that global client was not removed from the channel
5062 and checking for global users is not needed.
5064 * The silc_server_remove_clients_by_server now re-generates
5065 the channel keys correctly for those channels that had
5066 clients removed from them. Affected file silcd/server.c.
5068 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5070 * Found the reason of random crashes in the server. We weren't
5071 ignoring the SIGPIPE signal (which can be sent in write())
5072 and it crashed the server. Affected file silcd/silcd.c.
5074 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5076 * Assure that sock->user_data is not NULL in the function
5077 silc_server_packet_send in silcd/packet_send.c.
5079 * Disconnect the remote connection if it could not be added
5080 to any ID lists in the server. The affected file is
5083 * Check in silc_server_packet_send[_real/dest] that the
5084 socket is not disconnecting and ignore the data if it is.
5085 Affected file silcd/packet_send.c.
5087 * Define inline to __inline on native WIN32 compilation.
5088 Affected file includes/silcwin32.h.
5090 * Added some explicit type casts for inline code since MSVC
5091 require them. Affected files lib/silcutil/silcbuffer.h,
5092 lib/trq/silcdlist.h and lib/trq/silclist.h.
5094 * Print warning in log files from now on if the packet
5095 decryption fails. Affected file silcd/server.c.
5097 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5099 * Changed the `say' client operation's interface to accept
5100 new `type' argument to indicate the type of the message sent
5101 by the library. The application may filter the library's
5102 messages according the type. The affected file is the
5103 lib/silcclient/silcapi.h.
5105 * Added two new functions to lib/silcclient/silcapi.h:
5106 silc_client_del_client and silc_client_del_client_by_id.
5107 Affected file lib/silcclient/idlist.c.
5109 * Moved the clientincludes.h from includes/ to silc/ and
5110 serverincludes.h from includes/ to silcd/.
5112 * The modes for the CMODE and CUMODE are now passed as
5113 uint32 for application with COMMAND_REPLY. The affected
5114 file is lib/silcclient/command_reply.c.
5116 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5118 * /WHOIS without arguments shows client's own information.
5119 Affected file lib/silcclient/command.c.
5121 * Changed PING to not accept any arguments. The specs
5122 says that client can ping only the connected server so
5123 requiring an argument is not needed. Affected file is
5124 lib/silcclient/command.c.
5126 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5128 * Fixed a fatal bug in private message sending and reception
5129 encryption and decryption when using private message keys.
5130 The implementation was incorrect and did not follow the
5131 specification. It causd that some of the message were
5132 lost since it did not use the sending and receiving keys
5133 as the protocol suggests. This has been fixed and will cause
5134 incompatibilities with older clients when sending private
5135 message encrypted with private message keys. Affected files
5136 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
5137 and various other in Irssi SILC Client.
5139 Added `responder' boolean argument to the functions
5140 silc_client_add_private_message_key[_ske] to indicate when
5141 the key is added as responder or initiator of the key
5144 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5146 * Removed the silc_ske_check_version function and created
5147 a SilcSKECheckVersion callback. Added also a function
5148 silc_ske_set_callbacks that is now used to set all SKE
5149 callbacks. The callback functions are not given to
5150 the SKE functions anymore, but this function is used to
5153 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
5155 * Added `silc_version' argument to the silc_client_alloc
5156 to define the version of the application for the library.
5157 The library will use the version string to compare it
5158 against the remote host's (usually a server) version
5159 string. Affected file lib/silcclient/silcapi.h
5161 * Added the KE protocol context to Key Agreement context
5162 in client library so that we can abort the SKE if it
5163 is in process when we get timeout. Affected file is
5164 lib/silcclient/client_keyagr.c.
5166 * Do not resolve the client ID forever if it returns in the
5167 first time that such client does not exist. This was done
5168 for example with private message. Affected file is
5169 lib/silcclient/client_prvmsg.c.
5171 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5173 * Do not add regex.h for WIN32. The affected file
5174 includes/silcincludes.h.
5176 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
5177 not work yet 100%. It generates the DLL's automatically
5178 when compiling with --with-win32 under cygwin.
5180 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5182 * lib/contrib/regex.c is not compiled on WIN32.
5184 * Added silc_net_get_socket_opt function to the
5185 lib/silcutil/silcnet.h.
5187 * Added includes/silcwin32.h for WIN32 specific includes
5190 * Do not use ptime structure or any of the posix process
5191 functions on WIN32 in lib/silccrypt/silrng.c.
5193 * Added silc_gettimeofday to provide generic function
5194 for struct timeval on all platforms. Added the function
5195 to lib/silcutil/silcutil.h.
5197 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5199 * Moved the lib/silccore/silcsockconn.[ch] to the utility
5200 library as they clearly belong there. As a plus side we
5201 can make the actual socket connection routines platform
5204 Added also new generic function silc_socket_read and
5205 silc_socket_write (that used to be silc_packet_[read/write].
5206 The implementation of these are platform specific.
5208 * Added WIN32 specific routines of silc_socket_[read/write]
5209 to lib/silcutil/win32/silcwin32sockconn.c.
5211 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5213 * Added preliminary support for native WIN32 compilation under
5214 cygwin (using the -mno-cygwin option for GCC) to the
5215 ./configure.in.pre. The --with-win32 now prepares the
5216 compilation for native WIN32.
5218 * Rewrote the SILC Scheduler interface in the file
5219 lib/silcutil/silcschedule.h. The scheduler is now context
5220 based and does not have anymore any global static scheduler.
5221 Moved the Unix scheduler to the lib/silcutil/unix/ directory
5222 and created lib/silcutil/win32 directory for WIN32 based
5225 * Added Unix specific network routines to the
5226 lib/silcutil/unix/silcunixnet.c and the old
5227 lib/silcutil/silcnet.c includes now only generic routines.
5229 Added WIN32 specific network routines to the
5230 lib/silcutil/win32/silcwin32net.c.
5232 * Added Unix specific utility functions from the
5233 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
5235 * Added WIN32 SILC Scheduler to the file
5236 lib/silcutil/win32/silcwin32schedule.c. The code is of course
5239 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5241 * Do not handle JOIN notify in the server if the target client
5242 is not registered (idata->registered == FALSE). The affected
5243 file is silcd/packet_receive.c.
5245 * Update the nickrec->founder in event_cumode in the Irssi SILC
5246 client. Affected file irssi/src/silc/core/silc-channels.c.
5248 * Fixed the CUMODE_CHANGE notify handling in the server when
5249 server and router are announcing their clients on channels.
5250 Now the mode changes are saved and notified correctly. The
5251 affected file is /silcd/packet_receive.c.
5253 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
5254 They really did not replace the cache entry in the ID Cache.
5255 Now they do that. Affected file silcd/idlist.c.
5257 * Fixed the KICK notify handling in the Irssi SILC client to
5258 update the channel records so that the kicked client does not
5259 appear to be on the channel. The affected file is
5260 irssi/src/silc/core/silc-channels.c.
5262 * Always update the conn->current_channel when executing command
5263 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
5265 * Fixed the KILL notify handling in Irssi SILC client to remove
5266 the killed client on all channels.
5268 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5270 * Fixed the silc_parse_command_line to remove extra spaces
5271 from the start and end of the arguments. Affected file is
5272 lib/silcutil/silcutil.c.
5274 * Cancel and free any active protocol in the function
5275 silc_server_close_connection. Affected file silcd/server.c.
5277 * Cancel and free any active protocol in the function
5278 silc_client_close_connction. Affected file is
5279 lib/silcclient/client.c.
5281 * Do not execute the KILL command for clients that are in
5282 history (ie. they are not in the network). Affected file is
5285 * Fixed KILL notify handling, client does not crash anymore.
5286 Affected file irssi/src/silc/core/silc-channels.c.
5288 * Reduced the default packet buffer size from 2048 to 1024 in
5289 lib/silccore/silcpacket.c.
5291 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5292 counter to the SKE context that is incresed when the SKE library
5293 performs async operation outside the library. If the outside
5294 process frees the SKE context and FREED status will be set
5295 and the library will detect after the sync operation that the
5296 libary is freed. The affected files are
5297 lib/silcske/silcske[_status].[ch].
5299 * Resolve the client entry information in the function
5300 silc_client_channel_message to assure that NULL pointer is not
5301 passed as client entry to the application. */
5303 * Fixed the task timeout calculation to assure that there is
5304 never negative timeouts. The affected file is
5305 lib/silcutil/silcschedule.c.
5307 * Fixed the channel user mode notification sending in server.
5308 It was sent point-to-point to the router (or to server by router)
5309 but it needs to be destined to a channel. The routines now
5310 supports sending the channel user mode notifys to the channels
5311 when announcing clients and channels. Affected files are
5312 silcd/server.c and silcd/packet_receive.c.
5314 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5315 It did not actually replace the old channel entry in the cache.
5316 Affected file lib/silcclient/client_notify.c.
5318 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5320 * Fixed a possible crash in silc_packet_send_prepare. It now
5321 assures always that there is enough space in the buffer and
5322 at the tail area of the buffer (for MAC).
5324 Fixed the inbound buffer reallocation in silc_packet_read.
5325 It was old code and did not handle the reallocation correctly.
5328 The affected file is lib/silccore/silcpacket.c.
5330 * Fixed buffer overflow in silc_parse_nickname in the file
5331 lib/silcutil/silcutil.c.
5333 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5335 * make install generates new server keys only if there is not
5338 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5340 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5341 Added check that if the NOREPLY is set then we will not send
5342 the away message. This avoids infinite loop of away messages
5343 if both clients are away. The affected file is
5344 lib/silcclient/client_prvmsg.c.
5346 * Fixed client crash if /NICK was given without arguments.
5347 Affected file lib/silcclient/command.c.
5349 * Server does not send the invite list in INVITE command back
5350 to the client if the list was not altered. Added this notion
5351 to the protocol spec as well. Affected file silcd/command.c.
5353 Fixed possible crash in INVITE command by checking the
5354 value of silc_server_get_client_route command.
5356 * Fixed the INVITE notify type handling. The arguments are now
5357 taken in correct order and client does not crash. The affected
5358 file is irssi/src/silc/core/silc-channels.c.
5360 Removed the "Inviting xxx to channel" message from the
5361 client library away and let the application handle it.
5362 Affected file lib/silcclient/command.c. Added that message
5363 to Irssi SILC client's message formats.
5365 * Fixed CMODE command crash in client. It now checks the
5366 amount of arguments correctly and does not crash. The affected
5367 file is lib/silcclient/command.c.
5369 * Do not create new channel automatically in silc_channels_join
5370 but check whether the channel by that name already exists.
5371 Affected file irssi/silc/core/silc-channels.c.
5373 * Do not send the SERVER_SIGNOFF to router if the disconnected
5374 entity was the router. Affected file silcd/server.c.
5376 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5377 SILC client as it was missing from there.
5379 Added the handling of the KICK notify to the Irssi SILC client
5380 as it was missing. Added "you have been kicked" message to
5381 Irssi SILC client's message modules formats.
5383 Added the handing of the KILL notify to the Irssi SILC client
5384 as it was missing. Added the kill message module formats
5387 The affected file is irssi/src/silc/core/silc-channels.c.
5389 * The router did not save the channel mode the server announced.
5390 Affected file silcd/packet_receive.c.
5392 * Fixed a possible crash in INFO command in server. If the
5393 server did not provide the server info it crashed. Affected
5394 file silcd/command.c.
5396 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5398 * Fixed the GETKEY command in the server to check also the
5399 global list. Otherwise the GETKEY would not work correctly
5400 in normal SILC server. Affected file silcd/command.c.
5402 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5404 * Fixed GETKEY crash, it crashed if the command did not succseed.
5406 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5408 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5409 is now real and not just an macro interface to GMP.
5411 Removed the entire GMP from the source tree and imported new
5412 NSS MPI library instead. Reason for removing GMP is that it is
5413 extremely large and compiles extremely slow. The NSS MPI
5414 is only a few files and compiles in less than 10 seconds.
5415 The speed is also about the same as GMP. The MPI is imported
5416 to lib/silcmath/mpi.
5418 If the system has GMP installed we will still use the GMP.
5419 If it is not then the NSS MPI will be compiled.
5421 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5423 * Merged a long nickname (127 characters long) crash bugfix from
5424 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5426 * Merged a freed memory reference bugfix from Irssi CVS tree.
5427 Affected file irssi/src/core/commands.c.
5429 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5431 * Added the server's public key sving and verification to the
5432 server when performing the SKE. This was missing and the
5433 remote server's (or router's) public key was accepted without
5434 checking whether we have it previously or trust it at all.
5435 Affected file silcd/protocol.c.
5437 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5439 * Check in the silc_server_timeout_remote if protocol is active
5440 and make sure that the protocol's final callback is called so
5441 that all memory if freed. Affected file silcd/server.c.
5443 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5445 * silc_server_whois_send_reply crashed the server if the nickname
5446 was 127 characters long. Affected file silcd/command.c.
5448 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5450 * Added sanity check to the silc_server_new_client. If the hostname
5451 is provided inside username then check that the provided hostname
5452 really is the same as the resolved one. If the hostname was not
5453 resolved then check it from the public key. Affected file is
5454 silcd/packet_receive.c.
5456 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5457 if the server disconnected us and the connection is not valid
5458 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5460 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5461 the library to the lib/silcutil/silcutil.[ch].
5463 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5465 * Close log file after open. Affected file
5466 lib/silcutil/silclog.c.
5468 * Check whether sock == NULL in silc_client_send_packet and return
5469 if it is. Affected file lib/silcclient/silcclient.c.
5471 * Check rec->entry == NULL in the Irssi SILC Client before
5472 sending the channel message. Affecte file is
5473 irssi/src/silc/core/silc-servers.c.
5475 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5477 * Merged a splitted window bugfix from Irssi CVS tree. The
5478 affected file is irssi/src/fe-text/textbuffer-view.c.
5480 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5481 It did not print nickname.
5483 * Improved the distributions system a bit.
5485 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5487 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5488 irssi/src/fe-text/gui-window.c.
5490 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5491 to in-active server. The affected file is
5492 irssi/src/silc/core/client_ops.c.
5494 * Resolve the client in USERS command reply if the entry does
5495 not have username resolved. The affected file is
5496 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5497 command to WHOIS command to really resolve stuff. The USERS
5498 is not used any more in any critical section so WHOIS can
5499 be used even though it might be slower than IDENTIFY.
5501 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5504 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5506 * Changed the protocol API a bit more consistent in the
5507 lib/silccore/silcprotocol.[ch].
5509 * Changed the following headers to ROBODoc format:
5511 lib/silccore/silcpayload.h
5512 lib/silccore/silcprotocol.h
5513 lib/silccore/silcsockconn.h
5515 All core library headers are now formatted.
5517 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5519 * Fixed a bug in Irssi SILC client; do not show that you are
5520 server/router operator if you really are not. Affected file is
5521 irssi/src/silc/core/client_ops.c.
5523 * Renamed silc_command_free_payload to silc_command_payload_free.
5524 Affected file lib/silccore/silccommand.h
5526 * Added silcmath.h to include the prototoypes of various routines
5527 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5530 * Changed the following headers to ROBODoc format:
5532 lib/silccore/silcchannel.h
5533 lib/silccore/silccommand.h
5534 lib/silccore/silcid.h
5535 lib/silccore/silcidcache.h
5536 lib/silccore/silcmode.h
5537 lib/silccore/silcnotify.h
5538 lib/silccore/silcpacket.h
5539 lib/silcmath/silcmath.h
5541 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5543 * Added checking to the server code not to start the server if
5544 ciphers and stuff are not configured properly. Affected files
5545 silcd/serverconfig.[h] and silcd/server.c.
5547 * Changed the layout of the header files of the public interfaces
5548 in the SILC libraries. The new layout supports ROBODoc
5549 documentation tool (and some others) so that it is easy to create
5550 a library reference manual. All the other headers and source
5551 code must still follow the CodingStyle document. Also source
5552 code must not include these ROBODoc stuffs, only the headers.
5553 Furthermore, all public interface headers must now be named
5554 by using `silc' prefix, example: silcapi.h, silccipher.h.
5555 Some files were renamed due to this. All the other headers
5556 must not be used as public interfaces. I will update the
5557 CodingStyle document later. Changed following headers, so far:
5559 lib/silcclient/silcapi.h
5560 lib/silccore/silcauth.h
5561 lib/silccore/silcprivate.h
5562 lib/silccrypt/silcdh.h
5564 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5568 * Removed silc_client_packet_send_flush from the client library
5569 as it is not needed. Affected file lib/silcclient/client.[ch].
5571 * Added printing of message of unresolved authentication method
5572 to the Irssi SILC client. Added it to the module formats.
5573 Removed the same message from the client library.
5575 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5577 * Added new distribution feature, DISTLABEL. Every distribution
5578 can define own preprocessor label that can be used in the
5579 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5580 file distributions, acconfig.h.pre and prepare.
5582 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5584 * Added Makefile.defines_int to include the actual definitions
5585 for Makefile.defines.in. Tested the new distribution system,
5586 created distributions and tested installation.
5588 * Added AWAY message printing to the Irssi SILC client. Added
5589 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5591 * Added SCONNECT command to call the SILC's CONNECT command.
5592 Cannot use CONNECT directly since Irssi uses that internally.
5593 Affected file irssi/src/silc/core/silc-servers.c.
5595 Added ACTION local command. It is same as ME command but takes
5596 the channel as mandatory argument.
5598 Rewrote some of the Irssi's help files to suite for SILC
5601 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5603 * Added Makefile.defines[.in] that should for now on be included
5604 in all Makefile.am file in the source tree. That file includes
5605 all common compilation definitions for SILC source tree.
5607 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5609 * Minor changes to the ./prepare script to change the package
5610 name according the distribution name to the configure.in.
5612 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5614 * Created new distribution system. Added file `distributions'
5615 that defines all the distributions that can be created out of
5616 the SILC source tree. The ./prepare script now reads that
5617 file to determine how to prepare the distributions. The
5618 first argument to the ./prepare is the name of the distribution
5619 and second is the version of the distribution. If given
5620 without arguments it creates the default (toolkit) distribution
5621 with the default version (defined in ./prepare).
5623 All Makefile.am files that are subject to the distributions
5624 are now named as Makefile.am.pre. These are ./Makefile.am
5625 and lib/Makefile.am. Others may be changed later.
5627 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5629 * Added invite list, ban list, some key management and connection
5630 error message printing to module formats in the Irssi SILC client.
5632 * Added new silc_client_set_away_message to set the away message
5633 that is back to the person who sent private message. The
5634 affected file lib/silcclient/silcapi.h and the
5635 lib/silcclient/client_prvmsg.c.
5637 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5639 * Fixed the private message sending in the Irssi SILC client,
5640 added local command KEY to the Irssi SILC client.
5642 Added key management and key agreement message formats to the
5643 irssi/src/fe-common/silc/module-formats.[ch].
5645 Added USERS (alias WHO) printing, server/router operator
5646 indication and LIST command printing to the module formats.
5648 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5650 * Fixed channel joining notify handling, cumode notify handling
5651 from Irssi SILC client.
5653 * Added SILC specific module-formats to the Irssi SILC client so
5654 that SILC specific message hilighting, colors etc is possible.
5655 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5657 Added channel mode, channel user mode, actions, notices,
5658 whois and whowas printing to the the module-formats.c.
5660 * Fixed a bug in channel deletion in the server. The channel
5661 is not left to the cache even if the channel founder auth mode
5662 is set when there are no users anymore on the channel. Affected
5663 file silcd/server.c.
5665 * The silc_net_localhost now resolves the entire hostname including
5666 the domain name. Affected file lib/silcutil/silcnet.c.
5668 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5670 * Changed the ask_passphrase client operation to be ascynchronous.
5671 It has now a completion callback and a context that the
5672 application must call after it has got the passphrase from
5673 the user. Affected files lib/silcclient/silcapi.h,
5674 lib/silcclient/protocol.c, lib/silcclient/command.c and
5677 Added SilcAskPassphrase callback that the application calls
5678 to deliver the passphrase to the library.
5680 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5681 The public key verification and especially a certificate
5682 verification is asynchronous procedure.
5684 Added new SILC_SKE_STATUS_PENDING status to indicate the
5685 request is pending and a callback will be called to finalize
5688 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5689 indicate that remote end did not send its public key (or
5690 certificate), even though we require it. Added check for this
5691 condition in the SKE. This was a security bug, now fixed.
5693 Defined new SilcSKEVerifyCbCompletion callback that is called
5694 when the verification process is completed.
5696 The affected files lib/silcske/silcske_status.h and
5697 lib/silcske/silcske.[ch].
5699 * Changed the verify_public_key client operation to be async
5700 as well. Defined SilcVerifyPublicKey callback that is used to
5701 indicate the success of the public key verification process.
5703 Changed the server and client to use the new async client
5706 * Changed the Irssi SILC client's internal scheduler to be called
5707 twice as many times as it used to be. As a result the client
5708 should be a bit faster now. Affected file is
5709 irssi/src/silc/core/silc-core.c.
5711 * Added support to Irssi SILC client of asynchronous public key
5712 verification and passphrase inquiry. Affected file is
5713 irssi/src/silc/core/silc-core.c.
5715 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5717 * Do not say "You have left channel %s" in client library.
5718 Moved it to the application. Affected files are
5719 lib/silcclient/command.c and silc/client_ops.c.
5721 * Fixed silc_client_get_clients. Command context was not
5722 duplicated and was freed memory in the callback. Affected
5723 file lib/silcclient/idlist.c.
5725 * Do not say "you are now talking..." on JOIN command in the
5726 client library. The appliation must handle it.
5728 * Do not say ".. changed topic to" in command reply in the
5729 client libary. The application must handle it.
5731 * Fixed TOPIC command sending in the client library.
5733 * Fixed a memory leak in silc_client_command_free in the file
5734 lib/silcclient/command.c.
5736 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5738 * Imported a modified version of Irssi client to the source tree.
5739 The Irssi will be used to create a new client called
5740 Irssi SILC. Imported to irssi/.
5742 Added silc_core_init_finish function to the Irssi. Affected
5743 file irssi/configure.in.
5745 A lot changes in the Makefile.ams around the irssi tree.
5747 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5749 * Do not rehash if the new size is same as the old size of the
5750 hash table, in the silc_hash_table_rehash*. The affected file
5751 lib/silcutil/silchashtable.c.
5753 * Replaced hash_table_del_by_context calls from the server
5754 (when channel->user_list and client->channels) to the
5755 hash_table_del as it is sufficient and faster.
5757 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5759 * Added silc_hash_table_list, silc_hash_table_get and the
5760 SilcHashTableList structure to provide an alternative way to
5761 traverse the hash table. The affected files are
5762 lib/silcutil/silchashtable.[ch].
5764 * Changed the server's idlist routines to use the hash table
5765 routines to optimize the code.
5767 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5769 * Replaced the client entry's `channel' list and channel entry's
5770 `user_list' list to hash tables for optimized lookup. Changed
5771 the code to use the hash table interface around the code.
5772 Affected file lib/silcd/idlist.[ch].
5774 * Added `auto_rehash' boolean argument to the function
5775 silc_hash_table_alloc to indicate whether the hash table should
5776 auto-rehash when it thinks is appropriate time. It will
5777 increase the hash table size if the there is twice as much
5778 entries in the table than the size of the table, and will
5779 decrease the size if there are twice as less entries than
5780 the size of the table.
5782 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5784 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5786 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5788 * silc_idcache_purge_by_context deletes the entry now by context
5789 as it is supposed to do. Affected file lib/silccore/idcache.c.
5791 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5792 client is not anymore valid (WHOWAS givens the info) and not
5793 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5795 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5797 * Removed the `data' and `data_len' arguments from the ID Cache
5798 interfaces and added `name' argument. ID Cache does not handle
5799 anymore the binary data only a names associated with given ID.
5801 * When hashing a Client ID with silc_hash_id the entire ID is
5802 not hashed anymore, instead only the hash of the Client ID is
5803 hashed. This way we can access the Client ID from the cache
5804 with Client ID but with the hash of the ID (which is a hash of
5805 the nickname) as well without any difference in performance.
5807 Added also silc_idcache_find_by_id_one_ext to do one on one
5808 searching when we have the actual ID. Added also function
5809 silc_hash_client_id_compare. The affected files are
5810 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5812 * When hashing the name associated with a ID it is always done
5813 in lowercase. This way we can access the cache without worrying
5814 about case-sensitivity, even though, for example nicknames are
5817 * Fixed a bug in server with channel message sending. It put
5818 wrong ID type as destination ID. The affected file
5819 silcd/packet_send.c.
5821 * silc_idcache_del_by_context now deletes from all hash tables
5822 by context. Affected file lib/silccore/idcache.c.
5824 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5826 * Changed the client library to use the new ID Cache interface.
5827 Changes around the source tree.
5829 * Added silc_hash_table_rehash_ext to rehash with specific
5830 hash function. Affected file lib/silcutil/silchashtable.[ch].
5832 * Added silc_hash_string_compare to compare two strings in the
5833 hash table. Affected file lib/silcutil/silcutil.[ch].
5835 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5837 * Added new function silc_idcache_del_by_context into the
5838 lib/silccore/idcache.[ch].
5840 * Changed the server's ID list routines to use the new ID Cache
5841 interface. Changes around the source tree.
5843 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5845 * Added silc_hash_table_del[_by_context]_ext functions in to the
5846 lib/silcutil/silchashtable.[ch].
5848 Removed silc_hash_table_find_all* routines and added new
5849 silc_hash_table_find_foreach to replace them.
5851 Added silc_hash_table_replace_ext function as extended
5852 replacing function. Separated the simple hash table interface
5853 from the extended hash table interface in the file
5854 lib/silcutil/silchashtable.h.
5856 * Fixed minor bugs and changed it to use some of the new
5857 hash table functions in lib/silccore/idcache.c
5859 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5861 * Added new function silc_hash_table_find_all to return all keys
5862 in the hash table by the specified key. As the hash table is
5863 collision resistant it also makes it possible to have several
5864 duplicate keys in the hash table. This function may be used to
5865 find all of the keys from the hash.
5867 Added user_context arguments to the SilcHashFunction,
5868 SilcHashCompare and SilcHashDestructor to deliver user specified
5871 Added new fuctions silc_hash_table_find[_all]_ext to do
5872 extended lookup with specified hash and compare functions and
5873 specified user contexts.
5875 Added new function silc_hash_table_add_ext to add the key
5876 with specified hash function and user context.
5878 Added new function silc_hash_table_foreach to traverse all
5879 entrys in the hash table. Added SilcHashForeach callback
5882 Added new function silc_hash_table_del_by_context to delete
5883 the entry only if the context associated with the key matches.
5885 Affected files are lib/silcutil/silchashtable.[ch].
5887 * Removed silc_hash_[server/client/channel]_id and added just
5888 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5889 silc_hash_id_compare to compare two ID's using as the hash table
5890 comparison function. Added also silc_hash_data to hash
5891 binary data and silc_hash_data_compare to compare it.
5893 * Removed silc_idlist_find_client_by_hash as it is not needed
5894 anymore. Affected file silcd/idlist.[ch].
5896 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5897 to use internally the SilcHashTable. The new ID Cache is a lot
5898 faster than the old one. Some of the ID Cache interface was also
5899 rewritten and obsolete and stupid functions were removed.
5901 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5903 * Added entry_count field to the SilcHashTable to keep the number
5904 of the entries in the table. Implemented the function
5905 silc_hash_table_rehash. Added new function
5906 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5908 Fixed a minor bug in silc_hash_table_free.
5910 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5911 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5912 into the lib/silcutil/silcutil.[ch].
5914 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5916 * Implemented a collision resistant hash table into the
5917 lib/silcutil/silchashtable[ch]. See the header and the source
5918 for the SilcHashTable API.
5920 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5922 * Merged dotconf version 1.0.2 into lib/dotconf.
5924 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5926 * Do not compile anything in lib/silcsim/* if the SIM support
5927 is not enabled. The tree should now compile without problems
5930 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5932 * Compiled the SILC under cygwin. Compiled and tested briefly
5933 without problems. More tests needed. The SIMs didn't compile
5936 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5938 * Fixed possible crash in silc_get_username in the
5939 lib/silcutil/silcutil.c.
5941 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5943 * Fixed a va_arg in silc/client_ops.c.
5945 * Oops, RC5 routines were named AES and caused some problems
5946 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5948 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5950 * Added new SilcIDIP structure into the lib/silccore/id.h and
5951 replaced the old `ip' fields from all SILC ID's to that type.
5952 This is a step towards IPv6 support.
5954 The silc_id_get_len takes now the ID as an extra argument.
5955 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5956 both IPv4 and IPv6 based ID's.
5958 The affected files are lib/silccore/id.[ch] and other files
5959 around the tree using these routines.
5961 * Removed the ID length arguments in server from various
5962 silc_server_send_notify_* routines -> they are not needed
5965 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5967 * Fixed memory leak in silc_encode_pem_file in the file
5968 lib/silcutil/silcutil.c.
5970 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5972 * Check minor version as well in the SKE. Affected files are
5973 silcd/protocol.c and lib/silcclient/protocol.c.
5975 * Added --identifier option to the server so that an identifier
5976 can be when creating the public key for the server. Affected
5977 file is silcd/silcd.c.
5979 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5980 lib/silccrypt/silcpkcs.c.
5982 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5984 * Register default ciphers and stuff when using -C option with
5985 the server. Affected file sildc/silcd.c.
5987 * Put back the servers public key filename format, it is better
5988 than the new one. For now, the client keys are saved with the
5989 new filename format. The affected file silc/client_ops.c.
5991 * Implemented the Cipher API for the rest of the ciphers that
5992 did not implement it or implemented it the wrong way.
5994 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5996 * Register default ciphers and stuff when using the -S option
5997 in the client. Affected file silc/silc.c. Same also when
5998 creating new key pair with -C option.
6000 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6002 * Fixed the silc_verify_public_key client operation function to
6003 save the public keys differently. The fingerprint is now
6004 used as filename and not the hostname. This way also the
6005 client keys are saved uniquely and not with hostnames. The
6006 affected file is silc/client_ops.c.
6008 * Trimmed the silc_hash_fingerprint function to remove extra
6009 whitespaces from the end of the fingerprint. The affected
6010 file is lib/silccrypt/silchash.c.
6014 * Added silc_cipher_register_default function to register all
6015 default ciphers. It can be used when configuration files
6016 does not exist and the application does not want any specific
6017 ciphers in any specific order.
6019 The SilcDList is now used as silc_cipher_list dynamically
6020 allocated cipher list. Removed the static list all together
6021 and now all ciphers must be allocated to the dynamic list.
6022 The silc_cipher_alloc routine was changed to check only the
6025 All silc_cipher_* routines that used to return int returns
6028 The affected files lib/silccrypt/silccrypt.[ch].
6030 * The same thing was done to silc_hash_* as for silc_cipher_*
6031 routines. Affected files lib/silccrypt/silchash.[ch].
6033 * The same thing was done to silc_pkcs_* as for silc_cipher_*
6034 routines. Affected files lib/silccrypt/silcpkcs.[ch].
6035 Added also silc_pkcs_[un]register[_default] functions.
6036 Removed the data_context from the PKCS API.
6038 * Added silc_hmac_register_default function to register default
6039 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
6040 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
6041 to unregister all hmacs at once.
6043 * Register the default ciphers, hash functions, PKCSs and HMACs
6044 if client's configuration file does not exist. The affected
6047 * The client did not load the hash functions from the SIM
6048 modules at all. Added support for this. Affected file is
6049 silc/clientconfig.c.
6051 * When decoding public key with silc_pkcs_public_key_decode, check
6052 the supported algorithm only if PKCS are registered. Affected
6053 file lib/silccrypt/silcpkcs.c. The same was done with the
6054 silc_pkcs_private_key_decode.
6056 * Fixed the SILC List routines to keep the list always in order.
6057 It used to change the list's order when traversing the list but
6058 not it preserves the order. Affected file lib/trq/silclist.h.
6060 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6062 * Added the client library to use the SilcSocketConnection's
6063 reference counter (by silc_socket_dup) to prevent the bug that
6064 the socket object may be freed underneath async operation.
6066 * The name resolv library checking fixes in the configure.in.pre.
6069 * Created new version of the protocol drafts for future
6070 development. The -03 drafts are the ones that will be changed
6071 in the trunk now and the -02 will remain as they are.
6073 * Send list of CUMODE notifys to the router when announcing
6074 the channel users to the router. Affected file silcd/server.c.
6075 If the router receiving channel founder CUMODE for a channel
6076 that already has channel founder it will send CUMODE notify
6077 to the sender to remove the channel founder rights from the
6078 announced client. Affected file silcd/packet_receive.c.
6080 * The CUMODE notify may now use Server ID as well as the entity
6081 who changes the mode. Updated protocool specs.
6083 * Updated INSTALL and README files.
6085 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6087 * New web pages in the http://silc.pspt.fi. The pages was
6092 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6094 * Implemented the [DenyConnectin] config section in the server.
6095 Added silc_server_config_denied_conn to check whether incoming
6096 connection is denied. Affected file silcd/serverconfig.[ch].
6098 * Do not check the ports when checking the incoming configuration
6099 data if the port is 0, meaning any. Affected file is
6100 silcd/serverconfig.c.
6102 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6104 * Fixed buffer overflow in silc_string_compare in the file
6105 lib/silcutil/silcutil.c.
6107 * Fixed double free in silc_server_command_leave in the file
6110 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6112 * Fixed the version checking in the server. Affected file is
6115 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6117 * Fixed the configuration data fetching when accepting new
6118 connections in the server. Affected file silcd/server.c.
6120 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6122 * Added `sender_entry' argument to the function
6123 silc_server_packet_relay_to_channel so that we can check
6124 whether some destination actually belongs to the same route
6125 the sender belongs (ie, we must not resend the packet to the
6126 sender). Affected file silcd/packet_send.[ch].
6128 * Added `servername' field to the SilcClientEntry in the server
6129 to hold the name of the server where client is from. Affected
6130 file is silcd/idlist.h.
6132 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6134 * Moved the channel message encrypting in the router betwen
6135 router connections from silc_server_channel_message to the
6136 silc_server_packet_relay_to_channel since we want to check
6137 whether we have anybody channel before encrypting anything.
6138 Affected files silcd/packet_[receive/send].c.
6140 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6142 * Fixed the [AdminConnection] server config section to support
6143 multiple entries. Affected file silcd/serverconfig.c.
6145 * Added support into the server to check the validity of the
6146 incoming connection before executing any KE or authentication
6149 * The connection configuration is now saved to the KE and
6150 connection auth protocol contexts and not fetched anymore in
6151 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
6153 * The local hosts listenning address and port is also resolved
6154 now when starting the server. We want to have the socket object
6155 to include the real address and port for the listener. Added
6156 new function silc_net_check_local_by_sock into the files
6157 lib/silcutil/silcnet.[ch].
6159 * Fixed a broadcast bug in server -> do not broadcast if we
6162 * Fixed a routing bug. Do not route broadcast packets ever.
6163 Broadcast packets must be processed always and not routed since
6164 they may be destined to some other host than yourself and thus
6165 would get routed without no good reason. Affected file is
6168 * Added function silc_server_config_is_primary_route to check
6169 whether primary router connection has been configured (a router
6170 configuration that we are initiating). If there is not, we
6171 will assume that there is only two routers in the SILC network
6172 and we will use the incoming router connection as our primary
6173 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
6175 * Changed the order of the broadcasting. Broadcast _after_ the
6176 packet has been processed not before. Affected file is
6179 * Fixed a [ClientConnection] parsing bug. The port was never
6180 parsed correctly thus resulting to port 0. Affected file
6181 silcd/serverconfig.c.
6183 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
6184 argument and did not set the broadcast packet flag. Affected
6185 file silcd/packet_send.c. Fixed same bug in the function
6186 silc_server_send_notify as well.
6188 * If we receive NEW_ID packet for our own ID in the server, ignore
6191 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6195 * Removed the nickname from the Private Message Payload.
6196 Updated the code and the protocol specs.
6198 * Updated protocol specs for submitting to the IETF.
6200 * Tweaked the Random Number Generator a bit. Affected file
6201 lib/silccrypt/silcrng.c. Exported a new function
6202 silc_rng_[global]_add_noise which can be used to add more
6205 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6207 * Do not parse packets with different timeout when protocol
6208 is active -> may cause problem with rekey. Affected file
6211 * When server receives signoff notify it must not create
6212 new channel key if the client is on any channels since the
6213 sender of the signoff notify will create it.
6215 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6217 * Added printing of error messages during SKE protocol from the
6218 failure packet sent by server during SKE. Affected file
6221 * Removed the client's failure_callback handling with timeout
6222 and handle it immediately when received.
6224 * The SKE library returned wrong type in SUCCESS and FAILURE
6225 packets. They must be 32 bit MSB not 16 bit MSB.
6227 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6229 * Ok, rewrote the logic of the re-key and now it seems to work.
6230 I tested it on high traffic with frequent re-keys without
6231 problems. Added hmac_receive (and renamed hmac to hmac_send)
6232 in SilcClientConnection in lib/silcclient/client.h and
6233 in SilcIDListData in silcd/idlist.h. Also, removed the
6234 SilcPacketParserContext's cipher and hmac fields as they are
6235 not needed anymore and actually caused some problems when
6236 the ciphers and hmac's changed underneath the packet parser.
6238 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6240 * If re-key protocol is active then process the incoming packets
6241 synchronously since we must assure that icoming packets encrypted
6242 with the old key is processed before the new keys is set to
6243 use. This is true other packets than for REKEY packets.
6244 Affected file silcd/server.c. The same was done to client library
6245 as well, affected file lib/silcclient/client.c.
6247 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6249 * Fixed bug in client and server to accept the force send if
6250 the packet is send from silc_[server/client]_packet_process
6251 function. Otherwise the packets are never delivered, oops.
6253 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6255 * Disable force sending of packets when REKEY protocol is active.
6256 We must assure that no packet is sent directly when rekey is
6257 performed. All packets must be sent through packet queue.
6258 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
6259 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
6260 function is silc_[server/client]_packet_send_real to check
6263 * Replaced the SIM paths from example config files to
6264 /usr/local/modules. Also, make install creates now

6279 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6281 * When MAC computation fails the silc_packet_decrypt returned 0
6282 even though it was supposed to return -1. Fixed this. The
6283 affected file is lib/silccore/silcpacket.c.
6285 * Do not replace the config files in /etc/silc (in make install)
6286 if they already exist. Affected file ./Makefile.am.
6288 * Do not send re-key packets immediately but through packet queue.
6289 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6291 * Changed silc_net_check_host_by_sock to return FALSE if the
6292 IP/DNS could not be resolved. Though, it returns the IP address
6293 now even if it could not resolve it (but returns also FALSE).
6294 Affected file lib/silcutil/silcnet.[ch].
6296 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6298 * Added silc_pkcs_decode_identifier to decode the public key's

6304 contents of the specified public key file.
6306 * Changed the PKCS api to return the public key length when
6307 setting the public key.
6309 * Fixed a fatal bug in the public and private key file loading.
6310 Affected file lib/silccrypt/silcpkcs.c.
6312 * Execute the packet parsing for client with zero (0) timeout
6313 if the protocol is active. Affected file silcd/server.c.
6315 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6317 * Made the key generation options to the silcd program. Added
6318 -C option, equivalent to client's option.
6320 * Added new [ServerKeys] config section to the server. It
6321 configures the server's public and private key.
6323 * Defined generic Public Key Payload into the protocol
6324 specification to send specific type of public keys and
6327 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6328 public key or certificate.
6330 * Implemented the GETKEY command to the server and to the
6331 client library and on user interface.
6333 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6335 * Made preliminary `make install' work.
6337 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6339 * Added SilcServerRekey context into silcd/idlist.h.
6341 * Added the PFS support as defined in the specification to the
6342 SKE protocol. Affected files lib/silcske/*.c.
6344 * Added `ske_group' field to the SilcServerRekey context to hold
6345 the number of the SKE group that is used with PFS in re-key.
6346 Affected file silcd/idlist.h.
6348 * Added PFS re-key support to the server. Affected file is
6351 * Added silc_protocol_cancel to cancel execution of the next
6352 state of the protocol. Affected file is
6353 lib/silccore/silcprotocol.[ch].
6355 * Added the re-key support with and without PFS to the client
6356 library. Re-key is performed once in an hour, by default.
6358 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6359 Added silc_client_rekey_callback and silc_client_rekey_final.
6360 Affected files are lib/silcclient/protocol.[ch] and
6361 lib/silcclient/client.[ch].
6363 * Removed the `hmac_key' and `hmac_key_len' fields from the
6364 SilcClientConnection structure; not needed. Affected file is
6365 lib/silcclient/client.h.
6369 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6371 * Do not ask whether user wants to use the negotiated private key
6372 for private messages, just use it. Affected file is
6373 silc/local_command.c.
6375 * Added `send_enc_key' and `enc_key_len' fields to the
6376 SilcIDListData structure since they are needed in the re-key
6377 phase. Affected file is silcd/idlist.[ch].
6379 * Implemented the simple re-key protocol into the server.
6380 Affected files silcd/server.c and silcd/protocol.[ch]. The
6381 re-key will be performed once in an hour, by default.
6383 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6384 Added silc_server_rekey, silc_server_rekey_callback and
6385 silc_server_rekey_final.
6387 * Removed Tunneled flag from the protocol. Updated the code
6388 and the specifications.
6390 * Adde `pfs' field to the SilcIDListData to indicate whether
6391 the PFS is to be performed in the re-key. Affected file is
6394 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6396 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6397 int64 of at least the xintXX size. If void * is less that 4
6398 bytes uint32 * will be used. Defined bool as boolean.
6400 * Changed _ALL_ unsigned long and unsigned int to uint32,
6401 unsgined short to uint16 in the source tree.
6403 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6404 not handle clients that has entry->data.registered == FALSE.
6405 They are not in the network anymore. Affected file is
6408 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6410 * Implemented the sending of the SERVER_SIGNOFF notify in the
6411 server. Affected file is silcd/server.c.
6413 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6414 Added also silc_notify_payload_encode_args into the
6415 lib/silccore/silcnotify.[ch].
6417 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6418 Affected file silcd/packet_receive.c.
6420 * Implemented the SERVER_SIGNOFF notify handling in the client
6421 library. Affected file lib/silcclient/client_notify.c. Also,
6422 implemnted the printing of the SERVER_SIGNOFF info to the
6423 application. Affected file silc/client_ops.c.
6425 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6426 if the deleting was successful. Affected file silcd/idlist.[ch].
6428 * Added support for public key authentication in the connection
6429 authentication protocol in the client library. Affected file
6430 lib/silcclient/protocol.c.
6432 * Changed the server's silc_idlist_get_clients_by_* interface
6433 to support already allocated array so that new entries may be
6434 added to pre-allocated array. Affected file silcd/idlist.[ch].
6435 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6436 and command replies.
6438 * All command reply functions in the server now calls the
6439 pending command callback even if error occured. This way the
6440 error will be delivered to the client as well. Affected files
6441 silcd/command.c and silcd/command_reply.c.
6443 * Fixed INFO command to return local server's info if no server
6444 was provided. Affected file lib/silcclient/command.c.
6446 * Removed RESTART command for good. Updated the code and the
6449 * Rewrote parts of the task system. It is a bit simpler now.
6450 Removed unsued task priorities. The affected files are
6451 lib/silcutil/silctask.[ch].
6453 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6455 * Moved the USERS printing from the library to the application.
6456 Affected files lib/silcclient/command.c and silc/client_ops.c.
6458 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6462 * Added channel key re-key support. The re-key is perfomed
6463 only by the router and is done once in an hour. Added `rekey'
6464 field to the SilcChannelEntry in the server. Affected files
6465 silcd/server.c and silcd/idlist.h.
6467 * Added silc_task_unregister_by_context into the file
6468 lib/silcutil/silctask.[ch].
6470 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6472 * Added SILC_UMODE_GONE mode to indicate when the client is not
6473 present in the SILC network. Added also support to the local
6474 command AWAY that will set this mode. Added support of showing
6475 "xxx is gone" in WHOIS command. The USERS command shows the
6476 gone status as well.
6478 * Fixed setting server and router operator privileges in the
6479 server's UMODE command. Affected file silcd/command.c.
6481 * Merged the SKE KE1 and KE2 payloads into one payload. The
6482 new KE payload is equivalent to the old KE2 payload.
6484 Cleaned up the SKE Start Payload parsing. It now uses the
6485 simple buffer unformatting to do the parsing. A lot faster
6488 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6489 to the SKE that is used to indicate whether both of the SKE
6490 parties should perform authentication. By default only the
6491 responder performs authentication. By setting this flag also
6492 the initiator must do authentication. By default it is unset
6493 since in normal SKE case, client to server connection, only
6494 the responder should do authentication. When doing SKE between
6495 two clients both should perform authentication. Updated the
6496 code and the protocol specs.
6498 * A little fix to IDENTIFY command in the server. Search the
6499 client first by hash not nickname. Affected file is
6502 * Fixed the silc_client_close_connection to support closing
6503 the client to client connections wihtout deleting too much
6504 data. Affected file lib/silcclient/client.c.
6506 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6507 are received if protocol used to be active but is not anymore
6508 the application would crash due to NULL pointer dereference.
6509 Affected files silcd/server.c and lib/silcclient/client.c.
6511 * Added `hash' field to the SilcClientConnection to include
6512 the hash function negotiated in the SKE protocol.
6514 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6515 to set the channel founder authentication data. A client can
6516 claim the founder rights later by providing the authentication
6517 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6518 This way the channel founder can regain the channel founder
6519 privileges even it is left the channel. This works only on
6520 local server and the client must be connected to the same
6521 server to be able to regain the founder rights. Updated the
6522 protocol specs accordingly.
6524 Added support to the CMODE command in the client to set the
6525 founder auth data. Read the README to see how to set it.
6527 Added support to the CUMODE command to claim the founder
6528 rights. Read the README to see how to do it.
6530 Added support for the founder authentication to the Channel
6531 Entry in the server. Affected file silcd/idlist.h.
6533 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6534 server's CMODE command. Affected file silcd/command.c.
6536 * Added the following new functions into lib/silccore/silcauth.[ch]:
6537 silc_auth_get_method and silc_auth_get_data.
6539 * The server now saves the remote hosts public key to the
6540 SilcIDListData pointer. Affected file silcd/protocol.c.
6542 * The normal server now does not remove the channel entry from
6543 the cache if the founder authentication data is set. It used
6544 to remove it if the founder was the last one on the channel on
6545 the server and left the channel. The auth data is saved and
6546 if the channel is re-joined later the old entry is used with
6547 the old auth data. Affected files silcd/command_reply.c and
6550 * Removed the `pkcs' field from the SilcIDListData structure
6551 in the server; it is not used. Affected file silcd/idlist.h.
6553 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6555 * Fixed packet processing on slow links. Partial packets were
6556 never re-processed because the incoming data buffer was cleared
6557 by the application. Application must not directly clear the
6558 sock->inbuf, the packet processing routines handle it. Fixed
6559 this in client library and in server.
6561 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6563 * Fixed the WHOIS and IDENTIFY send reply function to really
6564 check whether to send list or just one entry. Affected file
6567 * Cleaned up the LEAVE command's channel key distribution. The
6568 affected file silcd/command.c.
6570 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6571 can enforce the channel mode as well. In that case the ID
6572 includes the ID of the server. The code now enforces the
6573 mode change if the router have different mode than the server.
6575 * The notify client operation with CMODE_CHANGE notify can now
6576 return NULL client_entry pointer if the CMODE was not changed
6577 by client. Application must check for this.
6579 * Added <Server ID> argument to INFO command to support server
6580 info fetching by Server ID.
6582 * Added silc_server_announce_get_channel_users to get assembled
6583 packets of channel users of the specified channel. Affected
6584 file silcd/server.[ch].
6586 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6587 was freed underneath the ID Cache.
6589 * Re-announce clients when the server received CHANNEL_CHANGE
6590 notify from the router. Affected file silcd/packet_send.c.
6592 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6594 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6595 crashed since it did not handle the fact that there is no cipher
6596 called "3" and didn't check the error condition. Now fixed.
6598 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6599 flag. It can be used to send message requests.
6601 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6603 * Implemented the RESTART command in the client.
6605 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6606 notice type messages. Added notice printing to the user
6609 * The channel keys are not re-generated if the channel's mode
6610 is PRIVKEY, ie private key on the channel exists. Affected
6611 files silcd/server.c and silcd/command.c.
6613 * Fixed a little bug in channel message delivery when channel
6614 private keys are set in the server. Affected file is
6615 silcd/packet_send.c.
6617 * Changed the setting on channel->on_channel = TRUE from the
6618 silc_client_save_channel_key to the JOIN command reply. The
6619 key payload is not received if the private channel key is set.
6620 Affected file lib/silcclient/command_reply.c and the
6621 lib/silcclient/client_channel.c.
6623 * When the CMODE_CHANGE notify is sent and the channel private
6624 key mode is removed the channel key must be re-generated in
6625 other cells as well. Added this support for the router in the
6626 silcd/packet_receive.c.
6628 * Added new local command NOTICE to send notice message on
6629 channel. Affected file silc/local_command.[ch].
6631 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6633 * Added new local command ME to the client. It is used to send
6634 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6635 some action. Affected file silc/local_command.[ch].
6637 * Changed channel_message and private_message client operations
6638 to deliver the message flags to the application. Added also
6639 the `flags' arguments to the silc_client_send_channel_message
6640 and silc_client_send_private_message functions. Affected file
6643 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6645 * Redefined the Private Message Payload to support private message
6646 keys and to support the new private message flags. Updated
6647 the protocol specs. Flags makes it possible to have for example
6648 CTCP style messages.
6650 * Added new type SilcPrivateMessagePayload and defined an API
6651 for it in the lib/silcclient/silcprivate.[ch].
6653 * Tested private message private keys successfully. Tested the
6654 private message key set, unset and list commands with the new
6657 * Redefined the Channel Message Payload to include the channel
6658 message flags (equal with private message flags) to support
6659 for example CTCP style messages.
6661 * Defined some of the message (for channel and private message)
6662 flags. Updated the protocol specs and added the flags to the
6663 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6665 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6667 * Added SilcKeyAgreementStatus type to the key agreement routines
6668 to indicate the current status and error if one occured.
6669 The status types are defined in the lib/silcclient/silcapi.h.
6671 * Added new local command KEY that is used to set and unset private
6672 keys for channels, set and unset private keys for private messages
6673 with remote clients and to send key agreement requests and
6674 negotiate the key agreement protocol with remote client. The
6675 key agreement is supported only to negotiate private message keys,
6676 it currently cannot be used to negotiate private keys for channels,
6677 as it is not convenient for that purpose.
6679 * Fixed a minor pending callback setting bug in the function
6680 silc_client_get_client_by_id_resolve, now the function works.
6681 Affected file lib/silcclient/idlist.c.
6683 * Added function silc_net_get_local_port to get local bound
6684 port by socket. Added to lib/silcutil/silcnet.[ch].
6686 * Added `sockets' and `sockets_count' fields to the SilcClient
6687 object. They hold the sockets of the listenning sockets in
6688 the client. Listenning sockets may be for example the key
6689 agreement server. Affected file lib/silcclient/client.[ch].
6690 Added functions the silc_client_add_socket and the
6691 silc_client_del_socket. They are exported to the application
6694 * Added ~./silc/clientkeys to support other client's public keys.
6696 * Renamed verify_server_key client operation to verify_public_key
6697 and added one argument to indicate the type of the connection
6698 (server, client etc.).
6700 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6702 * Added silc_server_connection_auth_request to handle the
6703 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6704 silcd/packet_receive.[ch].
6706 * Added silc_server_send_connection_auth_request into the
6707 silcd/packet_send.c to send the connection auth request packet.
6709 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6712 * Fixed the public key authentication in responder side in the
6713 server. The `auth_data' pointer includes the SilcPublicKey
6714 not the path to the public key. Affected file silcd/protocol.c.
6716 * Implemented the public key authentication in the initiator side
6717 in the server. Affected file silcd/protocol.c.
6719 * Removed the [RedirectClient] config section from the server
6720 configuration. Is not needed and I don't want to implement it.
6722 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6724 * Cleaned up the CMODE command in the server. It now works
6725 correctly and supports all the modes defined in the protocol.
6726 Affected file is silcd/command.c.
6728 * Added `hmac_name' field to the SilcChannelEntry in the server
6729 to hold the default HMAC of the channel. It can be set when
6730 creating the channel (with JOIN command). Affected files
6733 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6734 type to indicate the change of the current cipher and hmac
6735 on the channel. Client can safely ignore the <cipher> argument
6736 (if it chooses to do so) since the CHANNEL_KEY packet will
6737 force the channel key change anyway. The <hmac> argument is
6738 important since the client is responsible of setting the new
6739 HMAC and the hmac key into use.
6741 * Fixed the CMODE command in the client library as well.
6743 * Tested CMODE command in router environment successfully.
6745 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6747 * Show the version of the remote client (or server) when connecting
6748 to the server. It is logged to the log file. Affected file
6749 is silcd/protocol.c.
6751 * Fixed the KILLED notify handling in the client library. The
6752 client must be removed from all channels when receiving the
6755 Also, do not remove the client entry when giving the KILL
6756 command but when the KILLED notify is received.
6758 * Removed silc_idlist_find_client_by_nickname from the server.
6759 Not needed anymore. Affected files silcd/idlist.[ch].
6761 * Implemented the CHANNEL_CHANGE notify type handling to the
6762 server. Affected file silcd/server.c.
6766 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6768 * Added silc_server_send_notify_invite to send the INVITE
6769 notify between routers.
6771 * Implemented the INVITE command correctly to the server.
6773 * Implemented the INVITE notify type handling in the server.
6775 * Implemented the INVITE command to the client library and on the
6778 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6780 * Added function silc_server_get_client_resolve to find the
6781 client entry by ID from all ID lists and then resolve it
6782 (using WHOIS) if it cannot be found. Affected file is
6785 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6787 * Implemented the BAN command to the client library.
6789 * The JOIN command in the server now checks the invite list
6792 * Changed the silc_command_reply_payload_encode_va and the
6793 silc_command_payload_encode_va to support that if argument is
6794 NULL it ignores and checks the next argument. Affected file
6795 lib/silccore/silccommand.c.
6797 * Added silc_server_send_notify_ban to send the BAN notify
6798 type between routers.
6800 * Chaned the silc_notify_payload_encode to support that if
6801 argument is NULL it ignores and checks the next argument.
6802 Affected file lib/silccore/silcnotify.c.
6804 * Tested ban lists in router environment successfully.
6806 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6808 * Implemented BAN command to the server, in silcd/command.[ch].
6810 * Removed the BAN and INVITE_LIST modes from the CMODE command
6813 * Added function silc_string_match to regex match two strings.
6814 Affected files lib/silcutil/silcutil.[ch].
6816 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6818 * Redefined parts of the SilcChannelEntry in the server to support
6819 the new ban and invite lists.
6821 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6823 * Redefined the INVITE command. The same command can be used to
6824 invite individuals to the channel but also to manage the invite
6825 list of the channel (to add to and remove from the invite list).
6826 Updated the protocol specs.
6828 * Added new command SILC_COMMAND_BAN that can be used to manage
6829 the ban list of the channel. Updated the protocol specs.
6831 * Removed the channel modes: the SILC_CMODE_BAN and the
6832 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6833 in the CMODE command. The equivalent features are now available
6834 using INVITE and BAN commands. Updated the protocol specs.
6836 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6837 in the network about change in the current ban list. The notify
6838 type is not used by the client.
6840 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6841 support the invite lists.
6843 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6845 * Added new function silc_string_regexify that converts string
6846 including wildcard characters into regex string that can
6847 be used by the GNU regex library. Added into the file
6848 lib/silcutil/silcutil.[ch].
6850 Added silc_string_regex_combine to combine to regex strings
6851 into one so that they can be used as one regex string by
6852 the GNU regex library. Added into the file
6853 lib/silcutil/silcutil.[ch].
6855 Added silc_string_regex_match to match two strings. It returns
6856 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6858 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6860 * Imported GNU regex to the soruce tree into lib/contrib.
6861 Fixed some compiler warning from the regex.c.
6863 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6865 * Fixed MOTD command in the server to work in router environment.
6867 * Fixed the MOTD command in the client library to support
6868 the server argument in the command.
6870 * Added `nickname_len' argument to the silc_idlist_add_client
6871 in the server, as the `nickname' argument may be binary data
6874 * Added silc_idlist_get_channels to return all channels from
6877 * Implemented LIST command to the server. Affected file is
6880 * Implemented the LIST command to the client library and on the
6883 * Added [<user count>] argument to the LIST command reply.
6884 With private channels the user count is not shown.
6886 * Updated TODO and README.
6888 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6890 * The client entry's data.registered must be TRUE even with
6891 global client entry on global client list. The data.registered
6892 is used to check whether the client is anymore in the network,
6893 for example with WHOWAS command so it must be valid.
6895 * Fixed the WHOWAS command in the server. It now actually works
6896 in router environment. Added function into silcd/command_reply.c
6897 silc_server_command_reply_whowas_save.
6899 * Added silc_idlist_purge function to the silcd/idlist.c
6900 to periodically purge the ID Cache.
6902 * Fixed INFO command in the server. It works now in router
6903 environment. Added <server name> argument to the INFO command
6904 reply. Updated the protocol specs.
6906 * Fixed minor bug in silc_idcache_purge to not purge if the
6907 expire value is zero.
6909 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6910 they were buggy because of the WHOWAS information.
6912 * Fixed local command MSG to handle the async resolving of
6913 the remote client properly. It used to fail the first MSG.
6914 Affected file silc/local_command.c.
6916 * Added `data_len' field to SilcIDCache context.
6918 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6920 * Update TODO. Todo in commands in the server.
6922 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6924 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6925 used by routers as broadcast packet to inform other routers
6926 about the changed user mode.
6928 Implemented the notify handling in the server. Affected file is
6929 silcd/packet_receive.c. Added the function
6930 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6932 * Added new generic Channel Payload and deprecated the New Channel
6933 Payload. The New Channel Payload is now the generic Channel
6936 * Added new argument `mode' to the silc_server_send_new_channel
6937 as it is required in the Channel Payload now.
6939 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6940 and created a new and real SilChannelPayload to represent the
6941 new generic Channel Payload. Implemented the encode/decode
6942 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6944 * Added silc_server_get_client_channel_list to return the list
6945 of channels the client has joined for WHOIS command reply.
6946 Affected file silcd/server.[ch].
6948 * Implemented the channel list sending in the WHOIS command reply
6949 in server and in the client.
6951 Implemented the channel list displaying on the user interface
6952 as well. Affected file silc/client_ops.c.
6954 * Added silc_channel_payload_parse_list to parse list of Channel
6955 Payloads. It returns SilcDList list of SilcChannelPayloads.
6956 Client for example can use this function to parse the list of
6957 channels it receives in the WHOIS command reply. The caller
6958 must free the list by calling silc_channel_payload_list_free.
6959 Affected files lib/silccore/silcchannel.[ch].
6961 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6963 * Added one new argument <user mode> to the WHOIS command reply
6964 to return the mode of the user in SILC. Updated the protocol
6967 Implemented it to the server and client.
6969 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6971 * Fixed the mode printing on the user interface on joining.
6972 Affected file silc/client_ops.c.
6974 * Implemented the UMODE command and user modes in general to the
6975 client library and to the user interface.
6977 * Implemented the UMODE command to the server.
6979 * The server now sends UNKNOWN_COMMAND error status if client sends
6980 unknown command. Affected file silcd/command.c.
6982 * All server commands now handle the command identifier the right
6983 way when sending the command reply to the client. The client can
6984 use to identify the command replies with the identifier.
6986 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6988 * Added silc_server_get_client_route to resolve the route to
6989 the client indicated by the client ID. Affected file is
6992 * Added silc_server_relay_packet as general function to relay
6993 packet to arbitrary destination. This deprecates functions
6994 like _send_private_message_key, _relay_notify etc. Affected
6995 file is silcd/packet_send.[ch].
6997 Removed silc_server_send_key_agreement,
6998 silc_server_send_private_message_key and
6999 silc_server_packet_relay_notify functions from the file
7000 silcd/packet_send.[ch].
7004 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
7005 server. Affected file silcd/packet_receive.[ch].
7007 * Implemented the KILL command to the client. Implemented the
7008 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
7009 Affected files lib/silcclient/command[_reply].c and
7010 lib/silcclient/client_notify.c. Implemented the KILL notify
7011 printing in the user inteface.
7013 * Fixed a lot silc_parse_nick memory leaks from the client
7014 library in the file lib/silcclient/command.c.
7016 * Changed the silc_server_send_notify_on_channels's `sender'
7017 argument from SilcSocketConnection to SilcClientEntry to
7018 check the sender as entry and not as connection object and not
7019 to send to the client provided as argument. The affected file
7020 is silcd/packet_send.[ch].
7022 * The notify packets that are destined directly to the client used
7023 to not to be processed by the server. Now changed that and the
7024 server processes all notify packets. After relaying the packet
7025 to the client the notify packet is processed in the server.
7027 * The silc_server_free_client_data now checks whether there is
7028 pending outgoing traffic for the client and purges the data to
7029 the network before removing the client entry.
7031 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7033 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
7034 an client is killed from the SILC Network. Updated the protocol
7037 Added new function silc_server_send_notify_killed to the
7038 silcd/packet_send.[ch].
7040 * Added function silc_server_packet_relay_notify to relay notify
7041 packets that are destined directly to a client. In this case
7042 the server does not process the notify packets but merely relays
7043 it to the client. Affected file silcd/packet_send.[ch].
7045 Added also silc_server_packet_process_relay_notify to check
7046 whereto relay the notify. Affected file is
7047 silcd/packet_receive.[ch].
7049 * Implemented the KILL command to the server.
7053 * Added the backup schema desgined last fall to the protocol
7054 specs for everyone to see. The specification is in the
7055 *-spec-xx.txt draft and the packet type definitions for the
7056 backup routers is in *-pp-xx.txt draft. Thusly, added also
7057 new packet type SILC_PACKET_CELL_ROUTERS.
7059 * A big security problem in the implementation discovered. The
7060 signoff of an client did not cause new channel key generation
7061 which it of course should've done. The channel keys must be
7062 always re-generated when client leaves (or signoffs) the channel.
7063 The silc_server_remove_from_channels funtion now handles
7064 the channel key re-generation.
7066 * Added `sender' argument to the silc_server_send_notify_on_channels
7067 to not to send the client provided as argument. Affected file
7068 silcd/packet_send.[ch].
7070 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7072 * Implemented OPER and SILCOPER commands into the server and
7075 * Added silc_auth_verify and silc_auth_verify_data to verify
7076 the authentication directly from the authentication payload.
7077 It supports verifying both passphrase and public key based
7078 authentication. Affected file lib/silccore/silcauth.[ch].
7080 * Added `hash' field to the SilcIDListData structure. It is the
7081 hash negotiated in the SKE protocol. Affected file is
7084 * Slight redesigning of the SilcAuthPayload handling routines.
7085 Do not send SilcPKCS but SilcPublicKey as argument.
7087 * Implemented the public key authentication support to the
7088 serverconfig. The public key is loaded from the provided path
7089 and saved as authentication data to void * pointer. Thus,
7090 changed the unsigned char *auth_data to void *auth_data;
7092 * Fixed SHUTDOWN command to send the reply before the server
7093 is shutdown. :) Affected file silcd/command.c.
7095 * Fixed fatal bug in CONNECT command. The hostname was invalid
7096 memory and server crashed. Affected file silcd/command.c.
7098 * Fixed fatal bug in CLOSE command. The server_entry became
7099 invalid but was referenced later in the command. Affected file
7102 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7104 * Fixed fatal bug in failure packet handling. Server ignored
7105 the failure and thus crashed when it came.
7109 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7111 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
7112 that the command may be executed only once in (about) 2 seconds.
7113 The old SILC_CF_LAG flag is same but allows command bursts up
7114 to five before limiting.
7116 Added the support for CF_LAG and CF_LAG_STRICT flags to the
7117 server code. Various commands now includes the CF_LAG_STRICT
7118 flag to disallow any kind of miss-use of the command.
7120 * Fixed the silc_buffer_unformat to not to allocate any data
7121 if the length of the data is zero. It used to allocate the
7122 length + 1. Affected file lib/silcutil/silcbuffmt.c.
7124 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7126 * Changed the format of AdminConnection configuration section
7127 in the server. Added username of the admin to the format.
7128 Affected files silcd/serverconfig.[ch].
7130 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
7131 to return admin configuration data by host, username and/or
7134 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7136 * Implemented WHOWAS command to the server. Added the functions:
7138 silc_server_command_whowas_parse,
7139 silc_server_command_whowas_send_reply,
7140 silc_server_command_whowas_from_client and
7141 silc_server_command_whowas_from_server
7143 * Added <Client ID> argument to the WHOWAS command reply. Updated
7144 the protocol specs accordingly.
7146 * Implemented WHOWAS command and command_reply to the client
7149 Implemented the WHOWAS printing on the user interface.
7151 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7153 * Added new argument to the WHOWAS command reply, the real name.
7154 It is an optional argument. Updated the protocol specs.
7156 * Added SilcIDCacheDestructor callback that is registered when
7157 the SilcIDCache is allocated. The callback is called when
7158 an cache entry in the ID Cache expires, or is purged from the
7159 cache. Added into lib/silccore/idcache.[ch].
7161 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
7162 to destruct the client entries when the cache entry expires.
7163 Other ID Cache's in server and in the client library ignores
7166 * If the ID Cache entry's `expire' field is zero then the entry
7167 never expires. Added boolean `expire' argument to the
7168 silc_idcache_add function in the lib/silccore/idcache.[ch].
7169 If it is TRUE the default expiry value is used.
7171 * Added silc_server_free_client_data_timeout that is registered
7172 when client disconnects. By default for 5 minutes we preserve
7173 the client entry for history - for WHOWAS command.
7175 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7177 * Added support to the server to enforce that commands are not
7178 executed more than once in 2 seconds. If server receives
7179 commands from client more frequently, timeout is registered
7180 to process the commands. Affected file silcd/command.c.
7181 Added new function silc_server_command_process_timeout.
7183 * Changed NICK_NOTIFY handling in client library to check that
7184 if the client's nickname was changed, so there is no need to
7185 resolve anything from the server.
7187 * Removed error printing from the WHOIS and IDENTIFY commands.
7188 If error occurs then it is ignored silently in the client library.
7189 The application, however, may map the received error to
7190 human readable error string. The application currently maps
7191 the NO_SUCH_NICKNAME error to string.
7193 * Made the command status message public to the application. Moved
7194 them from lib/silcclient/command_reply.c to
7195 lib/silcclient/command_reply.h. The application can map the
7196 received command status to the string with the
7197 silc_client_command_status_message function.
7199 * Added check to the server to check that client's ID is same
7200 as the Source ID in the packet the client sent. They must
7203 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7205 * Added dist-bzip hook to the Makefile.am to make bzip2
7206 compressed distributions.
7208 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7210 * Server now enforces the maximum length for the nickname and
7211 the channel as protocol specification dictates. 128 bytes for
7212 nickname and 256 bytes for channel name.
7214 * Moved the WHOIS printing to the application. The client libary
7215 does not print out the WHOIS information anymore, the application
7216 must do it. Renamed silc_client_command_reply_whois_print to
7217 the silc_client_command_reply_whois_save.
7219 The client's idle time is also sent to the application now, and
7220 the idle is shown on screen.
7222 * Added silc_client_command_reply_identify_save to save the
7223 received IDENTIFY entries.
7225 * Do not check for channel private keys in message sending and
7226 reception if the channel does not have the PRIVKEY mode set.
7227 Affected file lib/silclient/client_channel.c.
7229 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7231 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
7232 just surfaced after chaning the JOIN procedure.
7234 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7236 * Added silc_client_get_clients_by_list to get client entries
7237 from Client ID list, that is returned for example by JOIN
7238 and USERS command replies. The application should use this
7239 function for example when JOIN command reply is received to
7240 resolve the clients already on the channel (library does not
7241 do that anymore as USERS command reply is not used in the JOIN
7242 procedure anymore). Affected files lib/silcclient/silcapi.h and
7243 lib/silcclient/idlist.c.
7245 * JOIN command reply and USERS command reply returns now SilcBuffer
7246 pointers instead of unsigned char pointers when returning
7247 the client list and mode list.
7249 * Added <Client ID> argument to the JOIN command reply, mainly
7250 for the server to identify for which client the command was
7251 originally sent. Updated protocol specs accordingly.
7253 * Added SilcDlist private_key pointer to the SilcChannelEntry
7254 in the client to support the channel private keys. Affected
7255 file is lib/silcclient/idlist.h.
7257 * Added SilcChannelPrivateKey argument to the function
7258 silc_client_send_channel_message so that application can choose
7259 to use specific private ke if it wants to. If it is not provided,
7260 the normal channel key is used, unless private keys are set.
7261 In this case the first (key that was added first) is used
7262 as the encryption key.
7264 * Implemented the support for channel private key handling.
7265 Implemented the following functions:
7267 silc_client_add_channel_private_key,
7268 silc_client_del_channel_private_keys,
7269 silc_client_del_channel_private_key,
7270 silc_client_list_channel_private_keys and
7271 silc_client_free_channel_private_keys
7273 Affected file lib/silcclient/client_channel.c.
7275 * Added the support for the private keys in the channel message
7276 sending and encryption and in the message reception and
7277 decryption. Affected funtions are
7278 silc_client_send_channel_message and silc_client_channel_message.
7280 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7282 * Added SKE's key verify callback to the client library's
7283 KE protocol context. Affected files lib/silcclient/protocol.[ch].
7285 * Removed the statement that server (or router) must send USERS
7286 command reply when joining to the channel so that the client
7287 knows who are on the channel. Instead, the client list and
7288 client's mode list is now sent in the JOIN command reply to the
7289 client who joined channel. This is better solution.
7291 * Added function silc_server_get_users_on_channel and function
7292 silc_server_save_users_on_channel to the silcd/server.[ch].
7294 * Removed function silc_server_command_send_users from the
7297 * Do not show topic on the client library anymore. The topic is
7298 sent in the command reply notify to the application and the
7299 application must show the topic now.
7301 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7303 * Added client searching by nickname hash into the IDENTIFY and
7304 WHOIS commands in the server as they were clearly missing from
7305 them. Affected file is silcd/command.c.
7307 * Fixed a bug in private message receiving in the client library.
7308 The remote ID was freed and it wasn't supposed, now it is
7311 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7313 * Minor fix to the channel payload; allocate the data area, as it
7314 needs to be of specific length.
7316 * If the key agreement port is zero then the operating
7317 system will define the bound port. Affected files are
7318 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7320 * Added new function silc_channel_payload_decrypt into the file
7321 lib/silccore/silcchannel.[ch].
7323 * Moved the channel message etc, check from silc_packet_decrypt
7324 to applications. The library calls now a generic
7325 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7326 when the packet is either normal or special. This was done to
7327 allow more wide range of checking that was not allowed when
7328 the code was in library. Now applications can do virtually any
7329 checks to the packet and return to the library the decision how
7330 the packet should be processed. Affected files are
7331 lib/silccore/silcpacket.[ch].
7333 Added silc_server_packet_decrypt_check to the server and
7334 silc_client_packet_decrypt_check to the client library.
7336 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7337 to send with specified source and destination information.
7339 * Channel message delivery between routers was broken after the
7340 channel key distribution was fixed earlier. The channel key
7341 was used be to distributed to other routers as well which is not
7342 allowed by the protocol. Now this is fixed and channel keys
7343 really are cell specific and the channel message delivery between
7344 routers comply with the protocol specification.
7346 * Fixed various commands in server to check also the global list
7347 for the channel entry and not just the local list. The affected
7348 file silcd/command.c.
7350 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7352 * Added assert()s to buffer formatting and unformatting routines
7353 to assert (if --enable-debug) when error occurs. Affected
7354 file: lib/silcutil/silcbuffmt.c.
7356 * Changed to auto-reconnect to check whether the remote host is
7357 router and register the re-connect timeout if it is. It used
7358 to check that whether we are normal server, but router must do
7359 auto-reconnect with another router as well. Affected file
7362 * Removed the [<key len>] option from CMODE command as the cipher
7363 name decides the key length, nowadays. See the defined ciphers
7364 from the protocol specification.
7366 * Added [<hmac>] option to the CMODE command to define the HMAC
7367 for the channel. Added SILC_CMODE_HMAC channel mode.
7369 * Added [<hmac>] option for the JOIN command so that user can
7370 select which HMAC is used to compute the MACs of the channel
7373 * Added Hmac field to the Channel Message Payload. The integrity
7374 of plaintext channel messages are now protected by computing
7375 MAC of the message and attaching the MAC to the payload. The
7376 MAC is encrypted. Now, it is clear that this causes some
7377 overhead to the size of the packet but rationale for this is that
7378 now the receiver can verify whether the channel message decrypted
7379 correctly and also when private keys are set for the channel the
7380 receiver can decrypt the packet with several keys and check from
7381 the MAC which key decrypted the message correctly.
7383 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7384 lib/silccrypt/silccipher.[ch].
7386 * Added silc_hash_len to return the digest length into the
7387 lib/silcrypt/silchash.[ch].
7389 * Rewrote parts of Silc Channel Payload interface in the
7390 lib/silccore/silcchannel.[ch]. The encode function now also
7391 encrypts the packet and parse function decrypts it.
7393 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7395 * Fixed a minor formatting bug in the SKE's key material processing.
7396 It actually might have processed the keys wrong way resulting
7399 * Redefined the mandatory HMAC algorithms and added new algorithms.
7400 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7401 and hmac-md5 truncated to 96 bits. The mandatory is now
7402 hmac-sha1-96. Rest are optional (including the one that used
7403 to be mandatory). Rationale for this is that the truncated HMAC
7404 length is sufficient from security point of view and can actually
7405 make the attack against the HMAC harder. Also, the truncated
7406 HMAC causes less overhead to the packets. See the RFC2104 for
7409 * Added new [hmac] configuration section. The SKE used to use
7410 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7411 is of course wrong. The official names that must be proposed in
7412 the SKE are the ones defined in the protocol specification
7413 (hmac-sha1-96 for example). The user can configure any hmac
7414 using any hash function configured in the [hash] section. At
7415 least, the mandatory must be configured.
7417 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7419 * Added HMAC list to the SKE proposal list. It has now both
7420 hash algorithm list and HMAC list. This makes the protocol
7421 incompatible with previous versions. The SKE now seems to work
7422 the way it is supposed to work, for the first time actually.
7424 * Defined plain Hash algorithms to the protocol specification.
7427 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7429 * Implemented support for key agreement packets into the server.
7430 Added functions silc_server_key_agreement and
7431 silc_server_send_key_agreement. Other than these functions,
7432 server has nothing to do with this packet.
7434 * Added support for private message key packets into the server.
7435 Added functions silc_server_private_message_key and
7436 silc_server_send_private_message_key.
7440 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7441 called in the protocol's final callback instead in the END
7442 protocol state. This makes a little more sense and in the same
7443 time in client we can use the same protocol routines for normal
7444 key exchange and to key agreement packet handling as well.
7446 * Added to both client's and server's KE protocol context the
7447 SilcSKEKeyMaterial pointer to save the key material. We will
7448 bring the key material to the protocol's final callback by doing
7449 this. The final callback must free the key material.
7451 * Added SKE's packet_send callback into client's KE protocol
7452 context so that the caller can choose what packet sending function
7453 is used. This way we can use different packet sending when
7454 doing normal SKE when doing key agreement packet handling (in
7455 the key agreement packet handling we do not want to encrypt
7458 * Implemented the responder side of the key agreement routines
7459 in the client. The client can now bind to specified port and
7460 accept incoming key negotiation. The key material is passed
7461 to the application after the protocol is over.
7463 * Implemented the processing of incoming Key Agreement packet
7464 in the client. Added function silc_client_key_agreement to
7467 * Implemented the intiator side of the key agreement routines
7468 in the client. The client can now initiate key agreement with
7469 another remote client. The key material is passed to the
7470 application after the protocol is over.
7472 * Created client_keyagr.c to include all the key agreement
7475 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7476 SILC_TASK_CALLBACK except that it is not static.
7478 * Created client_notify.c and moved the Notify packet handling
7479 from the client.[ch] into that file.
7481 * Created client_prvmsg.c and moved all private message and
7482 private message key routines from the client.[ch] into that file.
7484 * Create client_channel.c and moved all channel message and
7485 channel private key routines from the client.[ch] into that file.
7487 * Changed silc_client_get_client_by_id_resolve to resolve with
7488 WHOIS command instead of IDENTIFY command, in the file
7489 lib/silclient/idlist.c.
7491 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7493 * Implemented the SKE's responder side to the Client library.
7495 * When FAILURE is received to the protocol do not trust it
7496 blindly. Register a timeout to wait whether the remote closes
7497 the connection as it should do it, only after that process the
7498 actual failure. This was changed to both client and server.
7500 * Added client_internal.h to include some of the structures
7501 there instead of client.h in lib/silcclient/.
7503 * Added function silc_task_unregister_by_callback to unregister
7504 timeouts by the callback function.
7506 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7508 * Some "Incomplete WHOIS info" errors has been appearing on the
7509 log files. Took away the entry->userinfo check from WHOIS
7510 reply sending. The entry->userinfo is now " " if client did not
7511 provide one. I thought this was fixed earlier but something
7512 is wrong still. Let's see if the error still appears.
7514 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7516 * Fixed a minor bug in the login when the channel key is
7517 re-generated in the server. It used to generate the key in
7518 wrong order and thus caused problems in the channel traffic.
7520 * Fixed a minor bug in channel key distsribution after
7521 KICK command. The key was not sent to the router even though
7524 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7526 * Added silc_ske_process_key_material_data as generic routine
7527 to process any key material as the SILC protocol dictates. The
7528 function is used by the actual SKE library but can be used by
7529 applications as well. This relates to the private message keys
7530 and the channel private keys since they must be processed the
7531 same way the normal SILC session keys. The protocol dictates
7532 this. Affected files: lib/silcske/silcske.[ch].
7534 Added also silc_ske_free_key_material to free the
7535 SilcSKEKeyMaterial structure.
7537 * Defined silc_cipher_set_key function to set the key for
7538 cipher without using the object's method function. The affected
7539 files: lib/silccrypt/silccipher.[ch].
7541 * Implemented silc silc_client_add_private_message_key,
7542 silc_client_add_private_message_key_ske,
7543 silc_client_del_private_message_key,
7544 silc_client_list_private_message_keys and
7545 silc_client_free_private_message_keys functions in the
7548 Added functions silc_client_send_private_message_key to send
7549 the Private Message Key payload and silc_client_private_message_key
7550 to handle incoming Private Message Key payload.
7552 * Added Cipher field to the Private Message Key payload to set
7553 the cipher to be used. If ignored, the default cipher defined
7554 in the SILC protocol (aes-256-cbc) is used.
7556 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7558 * Removed lib/silcclient/ops.h file.
7560 Redefined parts of the SILC Client Library API. Created new
7561 file silcapi.h that deprecates the ops.h file and defines the
7562 published Client Library API. Defined also private message key
7563 API and channel private key API into the file.
7565 This is the file that the application must include from the
7566 SILC Client Library. Other files need not be included by
7567 the application anymore.
7569 * Added new key_agreement client operation callback and also
7570 defined the Key Agreement library API for the application.
7572 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7574 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7575 is used by clients to request key negotiation between another
7576 client in the SILC network. If the negotiation is started it
7577 is performed using the SKE protocol. The result of the
7578 negotiation, the secret key material, can be used for example
7579 as private message key.
7581 Implemented the Key Agreement payload into the files
7582 lib/silccore/silauth.[ch].
7584 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7586 * Redefined ciphers for the SILC protocol. Added some new ciphers
7587 and defined the key lengths for the algorithms. Changed the
7588 code accordingly. The default key length is now 256 bits.
7590 * Fixed SKE key distribution function silc_ske_process_key_material
7591 when the key length is more than 128 bits. The default key
7592 length in SILC is now 256 bits.
7594 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7595 to indicate unsupported algorithm.
7597 * Renamed rijndael.c to aes.c and all functions as well.
7599 * Fixed a long standing channel key setting bug in client library.
7600 Weird that it has never surfaced before.
7602 * Fixed bug in channel deletion. If the entire channel is removed
7603 then it must also delete the references of the channel entry
7604 from the client's channel list as the client's channel entry and
7605 the channel's client entry share same memory.
7607 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7609 * Implemented CONNECT and SHUTDOWN commands in the client.
7611 * Implemented CLOSE command to the client.
7613 * Added the function silc_idlist_find_server_by_name into the
7614 files silcd/idlist.[ch].
7616 Added the function silc_idlist_find_server_by_conn into the
7617 files silcd/idlist.[ch].
7619 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7621 * DIE command was renamed to SHUTDOWN. Updated the both code
7624 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7625 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7627 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7630 * Added function silc_server_create_connection function to create
7631 connection to remote router. My server implementation actually
7632 does not allow router to connect to normal server (it expects
7633 that normal server always initiates the connection to the router)
7634 so the CONNECT command is only good for connecting to another
7637 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7639 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7640 or some other client was kicked from the channel.
7642 Implemented the handling of the notify type to both client
7645 Implemented silc_server_send_notify_kicked to send the KICKED
7646 notify. It is used to send it to the server's primary router.
7648 * Implemented the KICK command into server and client.
7650 * Added `query' argument to the silc_idlist_get_client function
7651 to indicate whether to query the client from server or not if
7654 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7655 to indicate that the client is not channel founder.
7659 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7661 * Removed the rng context from SilcPacketContext structure and
7662 changed that the packet routine uses the Global RNG API.
7664 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7666 * Added support for quit message that client can "leave" on the
7667 channel when it quits the SILC. It is ditributed inside the
7668 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7670 Added silc_server_free_client_data that will take the
7671 signoff message as argument.
7673 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7675 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7677 * Updated parts of the protocol specification to keep it up
7680 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7682 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7683 payloads in one packet.
7685 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7686 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7687 use now the new List flag.
7689 * Also deprecated the following packet types: REPLACE_ID,
7690 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7692 * Added list support for Notify packet in server.
7694 * Added silc_server_send_notify_channel_change to send the
7695 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7696 the silc_server_send_replace_id.
7698 * Added silc_server_send_notify_nick_change to send the
7699 NICK_CHANGE notify type. Deprecates the function
7700 silc_server_send_replace_id.
7702 * Added silc_server_send_notify_join to send the JOIN notify type.
7703 Deprecates the function silc_server_send_new_channel_user.
7705 * Added silc_server_send_notify_leave to send LEAVE notify type.
7706 Deprecates the function silc_server_send_remove_channel_user.
7708 * Added silc_server_send_notify_cmode and
7709 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7710 types. Deprecates the silc_server_send_set_mode function.
7712 * Added SERVER_SIGNOFF notify type to indicate that server has
7713 quit. This means that all clients on the channel from that
7714 server will drop. This can be also used when netsplit happens.
7716 Deprecated REMOVE_ID packet type since it is not needed anymore
7719 Added silc_server_send_notify_server_signoff to send the
7720 SERVER_SIGNOFF notify type. Deprecates the function
7721 silc_server_send_remove_id.
7723 Added also silc_server_send_notify_signoff to send the
7724 SIGNOFF notify type.
7726 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7727 SILC protocol from this day on. Changed the protocol
7728 specification as well.
7730 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7731 notify type. It is used between routers to notify about
7732 topic changes on a channel.
7734 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7737 * Partly updated the protocol specification to comply with the
7738 changes now made. It is still though a bit outdated.
7740 * The JOIN notify type now takes one extra argument <Channel ID>.
7741 The packet used to be destined to the channel but now the
7742 JOIN type may be sent as list thus it is impossible to
7743 destine it to any specific channel. By adding this argument
7744 it is again possible.
7746 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7748 * Added CREDITS file. The CHANGES and CREDITS file will appear
7749 in the distribution as well.
7751 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7753 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7754 types in the server's silcd/packet_receive.c.
7756 * Implemented CMODE and CUMODE to work in router environment.
7758 * Fixed minor encoding and decoding buglet from the
7759 lib/silccore/silcmode.c.
7761 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7764 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7766 * Changed all SilcConfigServer* and silc_config_server* to
7767 SilcServerConfig* and silc_server_config*, respectively.
7770 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7772 * Associated the ID (client or server ID) to the Authentication
7773 Payload to avoid any possibility of forging. Updated the
7774 protocol specification and the code accordingly.
7776 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7778 * The RSA key length is now save to the RsaKey context in the
7779 key generation process in lib/silccrypt/rsa.c. The key length
7780 is now used to figure out the maximum size of the block allowed
7781 to be encrypted/signed.
7783 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7784 is equivalent to the silc_mp_mp2bin but does not allocate any
7787 * Changed silc_mp_mp2bin API to take length argument. If it is
7788 non-zero then the buffer is allocated that large. If zero, then
7789 the size is approximated using silc_mp_sizeinbase, which however
7792 * Created Global RNG API which is global RNG that application can
7793 initialize. After initializing, any routine anywhere in the
7794 code (including library) can use RNG without allocating a new
7795 RNG object. This was done to allow this sort of use of the
7796 RNG in code that has no chance to allocate RNG object. All
7797 applications currently allocate this and many routines in the
7798 library use this. Affected file lib/silccrypt/silcrng.[ch].
7800 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7801 it to use the Global RNG API.
7803 * Defined Authentication Payload into protocol specification that
7804 is used during SILC session to authenticate entities. It is
7805 used for example by client to authenticate itself to the server
7806 to obtain server operator privileges.
7808 Implemented this payload into the lib/silccore/silcauth.[ch].
7809 Implemented also routines for public key based authentication
7810 as the new protocol specification dictates.
7812 Moved definitions of different authentication methods from
7813 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7815 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7816 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7817 silc_pkcs_verify_with_hash functions into the file
7818 lib/silccrypt/silcpkcs.[ch].
7820 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7822 * The client entry's userinfo pointer must be always valid.
7823 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7824 will fail since it requires the userinfo. Now, the userinfo
7825 is allocated as "" if actual userinfo does not exist. Actually,
7826 it must exist and it is totally Ok to drop client connections
7827 that does not announce the userinfo. However, we will make
7828 this workaround for now.
7830 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7831 to return the remote port by socket.
7833 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7835 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7836 SILC_SERVER_PENDING_EXEC and added an new macro
7837 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7838 data or when error occurs while processing the pending command.
7840 Added new argument `destructor' into silc_server_command_pending
7841 and to the SilcServerCommandPending object. This destructor is
7842 now called after calling the pending callback or if error occurs
7843 immediately. If error occurs the actual pending callback won't
7844 be called at all - only the destructor. The destructor may be
7845 NULL if destructor is not needed.
7847 All this applies for client library code as well. Similar
7848 changes were made there as well for the pending commands.
7850 In the client, the application must now allocate the
7851 SilcClientCommandContext with the silc_client_command_alloc
7854 * Added reference counter to the SilcServerCommandContext. Added
7855 function silc_server_command_alloc and silc_server_command_dup
7858 Same type of functions added to the client library for the same
7861 * Removed the cmd_ident from IDListData away since it is now
7862 global for all connections. It is the command identifier used
7863 in command sending and with pending commands. The affected file
7866 * Added reference counter to the SilcSocketConnection objecet to
7867 indicate the usage count of the object. The object won't be
7868 freed untill the reference counter hits zero. Currently only
7869 server uses this, and client ignores it. The client must be
7870 set to use this too later. The affected files are
7871 lib/silccore/silcsockconn.[ch]. Added also the function
7872 silc_socket_dup to increase the reference counter.
7874 This was mainly added because it is possible that the socket
7875 is removed underneath of pending command or other async
7876 operation. Now it won't be free'd and proper DISCONNECTING
7877 flags, etc. can be set to avoid sending data to connection that
7878 is not valid anymore.
7880 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7881 the connection. After that it sets SILC_SET_DISCONNECTED.
7882 It is, however, possible that the socket data is not still freed.
7883 The silc_server_packet_process now checks that data is not
7884 read or written to connection that is DISCONNECTED. The socket
7885 get's freed when the reference counter hits zero.
7887 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7889 * Changed the client operation API: channel_message operation's
7890 `sender' is now the client entry of the sender, not the nickname
7891 and the `channel' is the channel entry, not the channel name.
7893 In the private_message operation the `sender' is now also the
7894 client entry of the sender not the nickname.
7896 Affected file is lib/silcclient/ops.h and all applications
7897 using the client operations.
7899 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7901 * Moved the calling of ops->connect() from connect_to_server_final
7902 into receive_new_id functin since that is the point when the
7903 client is actually allowed to send traffic to network. The
7904 affected file is lib/silcclient/client.c.
7906 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7908 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7909 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7910 (if needs broadcasting) instead of broadcasting the packets one
7911 by one which would make a burst in the network traffic.
7913 * Added `broadcast' argument to the functions in silcd/server.[ch]
7914 silc_server_create_new_channel[_with_id] to indicate whether
7915 to send New Channel packet to primary router.
7917 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7919 * Added new function into the silcd/server.[ch] files:
7920 silc_server_create_new_channel_with_id to create new channel with
7921 already existing Channel ID.
7923 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7924 lib/silccore/silcpacket.h. This packet is used t send list of
7925 Set Mode payloads inside one packet. Server uses this to set
7926 the modes for the channels and clients on those channels, that it
7927 announced to the router when it connected to it. The protocol
7928 specification has been updated accordingly.
7930 * The silc_server_new_channel did not handle the packet coming
7931 from normal server as it normally does not send that. However,
7932 when it announces its channels it does send it. Implemented
7933 the support for that.
7935 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7936 into the file lib/silccore/id.h.
7938 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7940 * Fixed memory leaks in the functions silc_idlist_del_client,
7941 silc_idlist_del_channel and silc_idlist_del_server in the file
7942 silcd/idlist.c. All of those leaked like a sieve.
7944 * Fixed some small memory leaks in the client's function
7945 silc_client_notify_by_server.
7947 * Added functions into silcd/server.c: silc_server_announce_clients,
7948 silc_server_announce_channels and silc_server_announce_server.
7949 These functions are used by normal and router server to announce
7950 to its primary router about clients, channels and servers (when
7951 router) that we own. This is done after we've connected to the
7954 These functions effectively implements the following packet types:
7955 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7956 and SILC_PACKET_NEW_ID_LIST.
7958 * Added new functions into the silcd/packet_receive.[ch]:
7959 silc_server_new_id_list, silc_server_new_channel_list and
7960 silc_server_new_channel_user_list to handle the incoming
7961 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7963 * Added support of changing Channel ID in the function
7964 silc_server_replace_id. If the server that announces a channel
7965 to the router already exists in the router (with same name but
7966 with different Channel ID), router is responsible to send
7967 Replace ID packet to the server and force the server to change
7968 the Channel ID to the one router has.
7970 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7971 client that the Channel ID has been changed by the router. The
7972 normal server sends this to the client. Client must start using
7973 the new Channel ID as the channel's ID.
7975 Implemented handling of this new type into lib/silcclient/client.c
7976 into the function silc_client_notify_by_server.
7978 * Added new function silc_idlist_replace_channel_id into the files
7979 silcd/idlist.[ch] to replace the Channel ID.
7981 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7983 * Call silc_server_command_identify_check always when processing
7984 the IDENTIFY command in silcd/command.c
7986 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7988 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7989 send keepalive packets. The packet can be sent by clients,
7990 servers and routers.
7992 Added function silc_socket_set_heartbeat into the file
7993 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7994 If not set, the heartbeat is not performed. The actual
7995 heartbeat is implemented in the low level socket connection
7996 library. However, application is responsible of actually
7999 Added silc_server_send_heartbeat to send the actual heartbeat
8000 packet into silcd/packet_send.[ch]. Server now performs
8001 keepalive with all connections.
8003 * Added silc_task_get_first function into lib/silcutil/silctask.c
8004 to return the timeout task with shortest timeout. There was a bug
8005 in task unregistration that caused problems. TODO has been
8006 updated to include that task system must be rewritten.
8008 * The client library will now resolve the client information when
8009 receiving JOIN notify from server for client that we know but
8010 have incomplete information.
8012 * Rewrote parts of silc_server_remove_from_channels and
8013 silc_server_remove_from_one_channel as they did not remove the
8014 channel in some circumstances even though they should've.
8016 * Encryption problem encountered in server:
8018 The LEAVE command used to send the Channel Key packet to the
8019 router immediately after generating it. However, the code
8020 had earlier sent Remove Channel user packet but not immediately,
8021 ie. it was put to queue. The order of packets in the router
8022 was that Channel Key packet was first and Remove Channel User
8023 packet was second, even though they were encrypted in the
8024 reverse order. For this reason, MAC check failed. Now, this
8025 is fixed by not sending the Channel Key packet immediately but
8026 putting it to queue. However, this is more fundamental problem:
8027 packets that are in queue should actually not be encrypted
8028 because packets that are sent immediately gets encrypted
8029 actually with wrong IV (and thus MAC check fails). So, packets
8030 that are in queue should be encrypted when they are sent to
8031 the wire and not when they put to the queue.
8033 However, the problem is that the current system has not been
8034 designed to work that way. Instead, the packet is encrypted
8035 as soon as possible and left to the queue. The queue is then
8036 just purged into wire. There won't be any fixes for this
8037 any time soon. So, the current semantic for packet sending
8040 o If you send packet to remote host and do not force the send
8041 (the packet will be in queue) then all subsequent packets to the
8042 same remote host must also be put to the queue. Only after the
8043 queue has been purged is it safe again to force the packet
8046 o If you send all packets immediately then it safe to send
8047 any of subsequent packets through the queue, however, after
8048 the first packet is put to queue then any subsequent packets
8049 must also be put to the queue.
8051 Follow these rules and everything works fine.
8053 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8055 * Added new function silc_server_remove_clients_by_server to
8056 remove all client entries from ID list when the server connection
8057 is lost. In this case it is also important to invalidate all
8058 client entires as they hold the invalid server entry. This
8059 fixes fatal bug when server has lost connection and will reconnect
8062 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8064 * Made some sanity checks to silc_server_daemonise like to check
8065 whether the requested user and group actually exists.
8067 * Added sanity check to SKE's silc_ske_responder_finish to check
8068 that the public and private key actually is valid.
8070 * Invalidate the client's nickname when receiving Replace ID
8071 packet and the Client ID is being replaced. This means that the
8072 server will query the nickname if someone needs it (client)
8075 * Sort the ID Cache in client library when the ID Cache data
8076 has changed (needs sorting).
8078 * Do not allow for SILC client to create several connections to
8079 several servers. The client does not support windows right now
8080 and generating multiple connections causes weird behaviour.
8082 Irssi-silc client does support windows and can handle several
8083 connections without problems, see: www.irssi.org and SILC plugin.
8085 * Fixed some places where client was added to the IDList. The
8086 rule of thumb is following (in order to get everything right):
8087 If the client is directly connected local client then the
8088 `connection' argument must be set and `router' argument must be
8089 NULL to silc_idlist_add_client function. If the client is not
8090 directly connected client then the `router' argument must
8091 bet set and the `connection' argument must be NULL to the
8092 silc_idlist_add_client function.
8094 * The funtion silc_server_packet_send_local_channel actually did
8095 not check whether the client was locally connected or not. It
8096 does that now. Fixed a bug related to LEAVE command.
8098 * Fixed Remove Channel User payload parsing bug in server's
8099 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
8101 * The server's silc_server_save_channel_key now checks also the
8102 global ID list for the channel as it might not be in the local
8103 list. Fixed a bug related to LEAVE command.
8105 * Is this the end of the [<unknown>] buglet that has been lurking
8106 around for a long time? A little for loop fix in server's
8107 silc_server_command_whois_parse that is used by both IDENTIFY
8108 and WHOIS command. At least, this was a clear bug and a cause
8109 of one type of [<unknown>] buglet.
8111 * WHOIS and IDENTIFY commands call the function
8112 silc_server_command_[whois/identify]_check function even if
8113 we are not router server.
8115 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8117 * Added --with-gmp configuration option. If set the GMP
8118 is always compiled in the SILC source tree. If not set then
8119 it is checked whether the system has the GMP3 installed. If
8120 it has then the GMP won't be compiled (the system's headers
8121 and library is used), if it doesn't have it then the GMP is
8122 compiled in the SILC source tree.
8124 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8126 * Changed RSA private exponent generation to what PKCS #1
8127 suggests. We try to find the smallest possible d by doing
8128 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
8129 not security fix but optimization.
8131 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8133 * Added new config entry [Identity] to fork the server and run
8134 it as specific user and group. A patch from Bostik.
8136 * Imported Dotconf configuration library into lib/dotconf.
8137 This will be used to create the SILC configuration files later.
8138 It will appear in the distsribution after this commit.
8140 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8142 * A big code auditing weekend happening. Auditing code for
8143 obvious mistakes, bugs and errors. Also, removing any code
8146 Removed files for being obsolete:
8148 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
8149 inline in the file lib/silcutil/silcbuffer.h)
8151 o lib/silcutil/silcbufutil.c (the header has inline versions)
8153 Changed code to fix possible error conditions:
8155 o The buffer formatting routines now check that the destination
8156 buffer really has enough space to add the data. This applies for
8157 both buffer formatting and unformatting
8158 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
8159 unformatting was changed to accomodate following rules:
8160 XXX_*STRING_ALLOC will allocate space for the data into the pointer
8161 sent to the function while XXX_*STRING will not allocate or copy
8162 the data into the buffer. Instead it sets the pointer from the
8163 buffer into the pointer sent as argument (XXX_*STRING used to
8164 require that the pointer must be allocated already). This change
8165 makes this whole thing a bit more consistent and more optimized
8166 (note that the data returned in the unformatting with XXX_*STRING
8167 must not be freed now). The routines return now -1 on error.
8169 o Tried to find all code that use buffer_format and buffer_unformat
8170 and added return value checking to prevent formatting and
8171 especially unformatting errors and possible subsequent fatal
8174 o Changed ske->x and ske->KEY to mallocated pointers in
8175 lib/silcske/silcske.h. Fixed possible data and memory leak.
8177 o Added return value checking to all *_parse* functions. Fixed
8178 many memory leaks as well.
8180 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
8181 so that buffer overflows would not happen. All code now also
8182 checks the return value as it can fail.
8184 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8186 * Added reconnection support to server if the normal server looses
8187 its connection to the router (for example if router is rebooted).
8188 The server performs normal reconnection strategy implemented
8189 to the server. Affected file silcd/server.c.
8191 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8193 * Added new packet type SILC_PACKET_SET_MODE that is used to
8194 distribute the information about changed modes (for clients,
8195 channels and clients channel modes) to all routers in the
8196 network. Updated the protocol specification accordingly.
8198 Added functions into silcd/packet_send.c and
8199 silcd/packet_receive.c: silc_server_send_set_mode,
8200 silc_server_set_mode.
8202 Added new files silcmode.[ch] into lib/silccore that implements
8203 the encoding and decoding of Set Mode Payload. Added new type
8204 SilcSetModePayload. Moved the definitions of different modes
8205 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
8207 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8209 * Oops, a little mistake in server's connection authentication
8210 protocol. The protocol is not ended with FAILURE but with
8211 SUCCESS if the authentication is Ok. :) Affected file is
8214 * Implemented NICK_CHANGE notify handling in server in the file
8215 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
8216 the local clients on the channel. After the changing nickname
8217 in router environment snhould work and the [<unknown>] nickname
8218 should appear no more.
8220 The silc_server_replace_id function that receives the Replace ID
8221 payload now sends the NICK_CHANGE notify type also in the file
8222 silcd/packet_receive.c
8224 * Changed WHOIS and IDENTIFY command to support the maximum amount
8225 of arguments defined in protocol specs (3328 arguments). This
8226 fixed a bug that caused problems when there were more than three
8229 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8231 * Added extra parameter, command identifier, to the
8232 silc_client_send_command so that explicit command identifier
8235 Changed that ID list routines uses specific command identifier
8236 when sending WHOIS/IDENTIFY requests to the server so that they
8237 can be identified when the reply comes back.
8239 Affected files lib/silcclient/command.[ch],
8240 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
8242 * Added `sender' argument to silc_server_packet_send_to_channel
8243 to indicaet the sender who originally sent the packet to us
8244 that we are now re-sending. Ignored if NULL. Affected file
8245 silcd/packet_send.[ch].
8247 * Added some server statistics support in silcd/server_internal.h
8248 SilcServerStatistics structure and around the server code. Also
8249 send some nice statistics information when client is connecting
8252 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8254 * Fixed channel ID decoding in server's JOIN command reply in
8255 silcd/command_reply.c
8257 * Fixed braodcasting of replace ID payload to not to send it if
8258 we are standalone server in silcd/packet_receive.c.
8260 * Fixed all channel message sending routines to not to send
8261 packets to clients that has router set, since they are routed
8262 separately in the same function earlier. Affects file
8263 silcd/packet_send.c and all channel packet sending functions.
8265 * In USERS reply, res_argv[i] are not allocated, the table
8266 is allocated. Thus changed that free the table, not its
8269 * In server's whois_check and identify_check if the client is
8270 locally connected do not send any WHOIS commands - they are not
8273 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8275 * Fixed some minor bugs in client when sending WHOIS command. The
8276 arguments was in wrong order.
8278 * Removed statis function add_to_channel from server in
8279 silcd/command.c that was previously used with the joining but
8282 * Tested USERS command in router environment successfully with two
8283 routers, two servers and two clients.
8285 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8287 * Reorganized the USERS command and command reply in client library
8288 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
8289 When the command is given by user we register a pending command
8290 callback that will reprocess the command after the reply has been
8291 received from the server. When reprocessing the packet we then
8292 display the information. Thus, the USERS information is displayed
8293 now in the command callback instead of in the command reply
8294 callback. The processing of the command is same as previously
8295 when server has sent the command reply in the JOINing process.
8297 * Added to USERS command in silcd/command_reply.c to join the client,
8298 we didn't use to know about, to the channel after we've created
8299 a client entry for it. Also, for clienet we did know already still
8300 check whether it is on the channel or not and add it if not.
8302 * Removed silc_server_command_join_notify as the function and its
8305 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8307 * Changed the client's pending command handling to the same as the
8308 server's pending command handling. It is also now possible to
8309 execute command reply functions from other command reply
8310 function as the function callbacks for commands and command
8311 replies are one and same. The pending commands are not static
8312 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8313 in client connection context. Thus, pending commands are server
8314 connection specific as it is convenient.
8316 Changed the function silc_client_command_pending and
8317 silc_client_command_pending_del and added new function
8318 silc_client_command_pending_check. Removed the
8319 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8322 * Added cmd_ident, current command identifier, to the client
8323 connection context in lib/silcclient/client.h to keep track on
8324 command identifiers used in command sending. Client's command reply
8325 function handling now supports the mandatory command identifiers.
8327 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8328 funtions in client to fully support pending command callbacks.
8330 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8331 as one of the arguments to the application in the command reply
8334 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8335 before first releasing SILC but came back. Now it is removed again
8336 and should come back nomore. The FORWARDED flag was used only
8337 by the JOINing procedure by forwarding the command packet to router.
8338 Now, the JOINing procedure has been changed to more generic (due
8339 to various router environment issues) and FORWARDED is not needed
8340 anymore for anything. The protocol specification is yet to be
8343 Now, removed silc_server_packet_forward from server and the flag
8344 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8346 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8348 * Renamed NAMES command to USERS command. The NAMES was named that
8349 due to historical reasons. Now it is renamed. Also, rewrote
8350 parts of the USERS command. The nickname list is not sent anymore
8351 by the server. Only Client ID and mode lists are sent in the USERS
8352 command. Changed this also to the protocol specification.
8354 The client now resolves the names and stuff after it receives
8355 the USERS list from the server when joining to the channel.
8357 * WHOIS and IDENTIFY commands has been changed to support multiple
8358 Client ID's per command. One can now search for multiple users
8359 in the network by sending only one WHOIS or IDENTIFY command.
8360 Changed the code and the protocol specifications.
8362 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8363 uses silc_server_command_whois_parse to parse the request. */
8365 * If normal server, do not parse the WHOIS and IDENTIFY requests
8366 before sending it to the router. Saves some time.
8368 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8370 * Fixed JOIN command on client library. Wrong number of arguments
8371 used to crash the client.
8373 * Added silc_server_channel_has_global function to check whether
8374 channel has global users or not.
8376 * Added silc_server_channel_has_local function to check whether channel
8377 has locally connected clients on the channel.
8379 * The silc_server_remove_from_one_channel now checks whether the
8380 channel has global users or not after given client was removed from
8381 the channel. It also checks whether the channel has local clients
8382 on the channel anymore. If it does not have then the channel entry
8383 is removed as it is not needed anymore.
8385 * The silc_server_notify now checks on JOIN notify whether the joining
8386 client is one of locally connected or global. If it is global then
8387 the channel has now global users on the channel and that is marked
8388 to the channel entry. Also, it now saves the global client to
8389 global list who is joining and JOINs it to the channel. This is
8390 for normal server, that is.
8392 Changed silc_server_send_notify_on_channel,
8393 silc_server_packet_relay_to_channel and
8394 silc_server_packet_send_to_channel check if we are normal server
8395 and client has router set (ie. global client) do not send the
8396 message to that client, as it is already routed to our router.
8398 * Implemented LEAVE notify type handling in silc_server_notify
8401 * Tested LEAVE command in router environment successfully. Tested
8402 with two routers, two servers and two clients.
8406 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8408 * Implemented SIGNOFF notify type handling in silc_server_notify
8411 * silc_server_remove_id now removes the client entry from all channels
8412 it has joined and thusly sends SIGNOFF notify type.
8414 * Rewrote the NAMES list generation in server by removing two excess
8415 loops. The lists are created now inside one loop.
8417 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8419 * silc_server_remove_channel_user checks now also global list
8420 for channel and client.
8422 * silc_server_new_channel_user checks now both local and global
8423 list for channel and client. Fixed a bug in client id decoding.
8424 Used to decode wrong buffer.
8426 * silc_server_channel_message checks now both local and global
8427 list for channel entry.
8429 * Tested channel joining (hence JOIN) in router environment
8430 successfully. Tested with two routers, two servers and two
8433 * Tested channel message sending in router environment successfully.
8435 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8437 * Added silc_server_save_channel_key into server.[ch] to save the
8438 received channel key in Channel Key payload processing. It is
8439 also used in JOIN command reply handling.
8441 Equivalent function silc_client_save_channel_key added into
8442 client.[ch] into client library.
8444 * Changed JOIN command reply to send information whether the channel
8445 was created or not (is existing already) and the channel key
8446 payload. Changed protocol specs accordingly.
8448 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8449 the request was sent by ID and not by nickname. Crashed on
8452 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8454 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8455 now correctly save the received data.
8457 * silc_server_free_sock_user_data now notifies routers in the
8458 network about entities leaving the network.
8460 At the same time implemented functions silc_server_remove_id
8461 and silc_server_send_remove_id to receive and send REMOVE_ID
8462 packets. The packet is used to notify routers in the network
8463 about leaving entities. The ID removed will become invalid in
8466 * Added function silc_idlist_del_server into server. Removes and
8467 free's server entry from ID list.
8469 * silc_server_private_message function now checks, if we are router,
8470 that the destination ID really is valid ID, naturally.
8472 * In router when NEW_ID packet is received (for new client) the
8473 hash of the Client ID is saved in the ID Cache but the
8474 client->nickname is set to NULL, instead of putting the hash
8477 IDENTIFY command now also checks that client->nickname must be
8478 valid. If it is not if will request the data from the server who
8479 owns the client. Added new function
8480 silc_server_command_identify_check.
8482 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8483 to set the command to already allocated Command Payload.
8485 * Tested private message sending in router environment with two
8486 routers, two servers and two clients. Fixed minor bugs and now
8489 * Fixed segfault from client's NAMES command. Used to crash if
8492 * Forwarded packets must not be routed even if it is not destined
8493 to the receiver. Changed server code comply with this.
8495 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8497 * Added `require_reverse_mapping' boolean value to ServerParams
8498 structure. If TRUE (not default) the server will require that
8499 the connecting host has fully qualified domain name.
8501 If the reverse mapping is not required and hostname could not be
8502 found the IP address is used as hostname.
8504 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8506 * Implemented version string checking to both client and server.
8507 The check is incomplete currently due to the abnormal version
8508 strings used in development version of SILC.
8510 * Changed all command functions in server to use the new
8513 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8515 * Changed char *data to unsigned char *data in ID Cache system to
8516 support binary data as ID Cache data. Changed code to support
8517 binary data in lib/silccore/idcache.c.
8519 * Renamed silc_server_packet_relay_command_reply to
8520 silc_server_command_reply as it is normal packet receiving
8521 function. Rewrote the function to accept command replys for
8522 servers and not only for clients.
8524 * Mark remote router always as registered server if we are connecting
8525 to it. Otherwise, commands sent by the router to us are ignored.
8527 * All ID List find routines now returns the ID Cache Entry pointer
8528 as well if requested.
8530 * WHOIS command works now in router environment, tested with two
8531 routers, two servers and two clients.
8533 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8534 in router environment (as it is almost equivalent to WHOIS) but
8535 hasn't been tested thoroughly. Added new functions:
8537 silc_server_command_identify_parse
8538 silc_server_command_identify_send_reply
8539 silc_server_command_identify_from_client
8540 silc_server_command_identify_from_server
8542 * Disabled route cache adding because adding two different ID's with
8543 same IP replaces the old cache entry thus giving wrong route.
8544 The entry->router->connection is always the fastest route anyway
8545 so route cache may not be needed. Of course, new routes maybe
8546 established after receiving the ID when the entry->router->connection
8547 might not be anymore the most optimal.
8549 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8551 * Add route cache for received ID for fast routing.
8553 * Added silc_server_packet_route to route received packet on router
8554 that is not destined to us.
8556 * Renamed silc_server_get_route to silc_server_route_get.
8558 * Added id_string and id_string_len fields into SilcServer to
8559 include encoded ServerID for fast comparing without excess
8560 encoding of the ID's.
8562 * Cleaned up WHOIS command on server side. Added following static
8565 silc_server_command_whois_parse
8566 silc_server_command_whois_check
8567 silc_server_command_whois_send_reply
8568 silc_server_command_whois_from_client
8569 silc_server_command_whois_from_server
8571 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8572 arguments in command replies. All command functions should be
8573 updated to use this macro.
8575 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8577 * Minor typo fixes on command reply handling on server.
8579 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8581 * Added silc_server_command_add_to_channel internal routine to add
8582 the client to the channel after router has created the channel and
8583 sent command reply to the server.
8585 * Added generic silc_server_send_command to send any command from
8588 * Use static buffer with ID rendering instead of duplicating data.
8590 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8592 * Fixed a channel user mode bug when joining to a channel server gave
8593 everybody channel founder rights, oops.
8595 * We mark ourselves as the router of the incoming server connection
8596 if we are router ourselves. This way we can check in some packet
8597 sending functions whether it is locally connected server. For
8598 incoming router connections we put NULL.
8600 * For router sending packets locally means now always sending the
8601 packet cell wide; to local clients and local servers. For normal
8602 server sending packet locally means sending it to only local
8605 * Fixed the JOIN command to really work in router environment. If the
8606 channel is created it is always created by the router. Router is
8607 also responsible of making the initial joining to the channel,
8608 sending JOIN notify to the sending server and distributing
8609 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8610 does not exist server doesn't do anything else but forward the
8611 command to the router which performs everything.
8613 * Added silc_server_send_channel_key function to send the Channel Key
8616 * Added silc_server_create_channel_key to create new channel key. The
8617 channel key is now re-generated everytime someone joins or leaves
8618 a channel, as protocol dictates. Note: channel->key_len is the
8621 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8623 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8624 packet_receive.[ch] to separate packet sending and receiving
8625 routines. The server.[ch] now includes everything else including
8626 actual packet processing (writing and reading data) and other
8629 Renamed silc_server_private_message_send_internal to
8630 silc_server_send_private_message. The routine is still though
8631 used only to relay private messages as server does not send
8632 private messages itself.
8634 Renamed silc_server_new_channel to silc_server_create_new_channel
8635 and added new function sicl_server_new_channel that handles the
8636 incoming New Channel packet. Added also new sending function
8637 silc_server_send_new_channel to send New Channel Payload.
8639 * Added new function silc_server_notify to process incoming notify
8640 packet to the server/router. Server may then relay the notify
8641 to clients if needed.
8643 * Added new function silc_server_new_channel_user to process incoming
8644 New Channel User packet. Router will redistribute the packet and
8645 send JOIN notify to its local clients and locally connected servers
8646 if needed. Normal server will send JOIN notify to its local client
8647 on same channel when received this packet. Added also corresponding
8648 sending function silc_server_send_new_channel_user to sent the
8651 * Added boolean route argument to send_notif_to_channel and
8652 packet_send_to_channel functions to attempt to route the packet
8653 if it is TRUE and send only locally if it is FALSE.
8655 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8657 * silc_server_replace_id now broadcasts the received replace ID
8658 packet if it is not broadcast packet already. The router must
8659 broadcast to inform other routers about changed ID.
8661 * Added backpointer to server's router into SilcServer context in
8662 silcd/server_internal.h.
8664 * Fixed silc_server_packet_broadcast to send correct broadcast
8667 * The channel key is now distributed to the local client as soon
8668 as it is received from the router (in router environment) so that
8669 no other packet may be sent for the channel until client has
8672 * silc_server_remove_channel_user now broadcasts the received
8673 Remove Channel User packet if it is not broadcast packet already.
8674 The router must broadcast to inform other routers about removed
8677 * Added users field into SilcPacketContext that is a reference count
8678 of the context. One can increase the reference count by calling
8679 silc_packet_context_dup which is now changed to just increase the
8680 reference count instead of duplicating the data. The reference
8681 count is decresed by calling silc_packet_context_free that will
8682 free the data after the reference count hits zero.
8684 For now on the packet context and everything allocated into it
8685 (including the raw packet from network) must be freed by calling
8686 the new silc_packet_context_free function. Added also new function
8687 silc_packet_context_alloc that must be used now to allocate the
8688 context. This also means that if a routine is asynchronous from
8689 silc_[client/server]_packet_parse_type the packet context must
8690 be duplicated by calling silc_packet_context_dup. Otherwise it
8691 gets free'd after silc_[client/server]_packet_parse_type returns.
8692 Also, one must remember that if packet is duplicated then its
8693 reference count must be decresed by calling the free function as
8694 many times as it was duplicated.
8696 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8697 from both client and server.
8699 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8701 * Made joining to a channel working in router environment.
8703 * Cleaned up JOIN command on server side and create function
8704 silc_server_command_join_channel internal routine to make the
8707 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8709 * Changed silc_command_pending list to SilcDList. Also, added
8710 `ident' field to SilcServerCommandPending structure to identify
8711 the reply and to call correct callback.
8713 Added silc_server_command_pending_check function to replace the
8714 corresnponding macro. The silc_command_pending list is not
8717 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8718 to set identifier to previously allocated Command Payload. It
8719 is used to set identifier for command when resending Command
8722 * Added silc_command_payload_encode_payload to encode Command
8723 Payload buffer from SilcCommandPayload structure.
8725 * Added silc_argument_payload_encode_payload to encode Argument
8726 payload buffer from SilcArgumentPayload structure.
8728 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8730 * Changed WHOIS command to support router connection on server side.
8731 The whois request is always sent to router unless the server is
8732 standalone server. After server has received the reply from the
8733 router will it send the reply to the client.
8735 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8736 broadcast received broadcast packet. The function is used only
8737 by router. The broadcast packet is always sent to the router's
8740 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8741 render given ID to printable string, for log files for example.
8743 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8745 * Made basic router to router connections working. At least they
8746 can now connect to each other but nothing really works the way
8747 they are supposed - yet.
8749 * Added new initiator token to RouterConnection configuration
8750 file in silcd/serverconfig.[ch]. It is used to tell whether we
8751 are the initiator to the remote router or whether we'll expect
8752 the other end to connect.
8754 * Moved registering of listener task to silc_server_init, hence
8755 the server starts listenning as soon as it is run, even if it
8756 does not have connections to other routers. Let's see how well
8759 * Changed default connection retry timeouts for more suitable in
8762 * Removed cipher and such arguments from silc_idlist_add_client
8763 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8764 Added new function silc_idlist_add_data to add the keys and stuff
8767 * Added SilcIDListData structure and added it to SilcClientEntry
8768 and SilcServerEntry as their first field in the structure. This
8769 way we can explicitly cast the ID entries to the SilcIDListData
8770 structure and get common data for the entries. In past, we had
8771 to first check what type of connection it is and then cast it to
8772 correct ID entry type. Now, we can directly cast the opaque
8773 pointer to the SilcIDListData (no matter what ID entry it actually
8774 is) and get the data needed.
8776 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8778 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8779 in some circumstances even if threre were timeout tasks, though not
8780 IO tasks, but tasks anyway. Now fixed.
8782 * Defined SilcServerConnection structure to hold connection specific
8783 stuff about directly connected servers and routers. The definition
8784 is currently in silcd/server_internal.h. I thought about having
8785 a bit more important role fro this struct but for now it is used
8786 only when connecting to other server (or router actually).
8788 * Added connecting retry support in server when connecting to
8789 router(s). The retry feature implement exponential backoff
8790 algorithm. Also, added SilcServerParams structure to hold default
8791 parameters for server. For now, it include these retry settings
8792 and are hard coded. After server is moded to be as Silc Server
8793 Library this structure will be more important.
8795 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8797 * Changed client librarys channel->clients table to SilcList and
8798 changed code accordingly.
8800 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8802 * Changed client's channel table to SilcList and changed code
8803 accordingly. Also changed SilcChannelClientEntry to include back-
8804 pointer to the channel so that client entry can use that structure
8805 as list as well and we have fast cross-reference to the channel.
8806 This change dramatically decreased the complexity of channel
8807 handling with client entry and vice versa (removed one extra
8808 loop when searching for channel entry from many functions).
8810 * Changed server->sim from table to SilcDList and changed code
8813 * NAMES command can now be used from user interface. It will show
8814 the user list on the channel, neatly.
8816 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8817 Code now saves realname of the user if it becomes available.
8819 * Renamed configure.in to configure.in.pre and made ./prepare
8820 script to automatically add correct version string to
8821 configure.in which it creates from configure.in.pre.
8823 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8825 * NAMES command reply now shows users mode with the nickname when
8828 * Moved silc_client_ch[u]mode[_char] functions from
8829 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8830 place sucks, they are utility functions and should be in some
8833 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8835 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8838 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8842 * Added TRQ (efficient deque and list library) into lib/trq. This is
8843 a very good list library that is currently used in the SILC. Defined
8844 SilcList API over the library because I didn't like the API very
8845 much. See lib/trq/silclist.h for the API and examples of how to
8846 use the API. Fixed various places in the code to use the new
8847 SilcList API. The SilcList is meant for lists that has a structure
8848 already defined as a list. It is not suitable to add just some
8849 context to the list (in TRQ, the context is the list actually).
8851 So, I defined SilcDList that can be used for the purpose where
8852 predefined list structure does not exit. This can be used as
8853 such list. Now some context just can be added to the SilcDList.
8854 Currently this list is not used in the SILC just yet, though there
8855 are a lot places where this can replace dynamically allocated
8856 tables and I will fix these places, later, to use SilcDList.
8857 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8858 and use TRQ internally).
8860 Also fixed some annoying warning messages that the original TRQ
8861 code generated. Also minor changes to TRQ's Makefile.in.
8863 * Added support for querying by Client ID to both WHOIS and
8864 IDENTIFY commands into server, as required by the protocol.
8866 * Removed method function pointers from SilcBuffer structure. They
8867 weren't used to anything and just increased the context size for
8868 no good reason. This change also made silc_buffer_alloc and
8869 silc_buffer_free functions inline functions.
8871 * Disabled command flooding detection support until it's fixed so
8872 that it accepts commands in but does not execute them more than once
8875 * Added silc_net_localhost(), to return local hostname, into
8876 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8877 that must be initialized before calling silc_client_init.
8879 * Added new function: silc_server_send_notify_on_channels to send
8880 notify messages to all channels client has joined. It is assured
8881 that the message is sent only once per client.
8883 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8884 lib/silcutil/silcutil.[ch] as silc_format function. The new
8885 function is generic and is used by server as well, not only by
8886 the logging routines.
8888 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8889 the provided version string was not acceptable. Added new function:
8890 silc_ske_check_version into lib/silcske/silcske.h. The function
8891 must be implemented by the application (client or server) and it
8892 does not reside in the SKE library. The function checks the version
8893 string remote end sent.
8895 * Added back pointers (to opaque context and to SilcSocketConnection)
8896 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8898 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8899 duplicate packet context structure.
8901 * Changed `notify' client operation to send same arguments as client
8902 receives from server except for ID's. ID's are mapped to correct
8903 ID entry and that is returned. Also, if channel entry is not sent
8904 by server but the notify is for channel the channel entry is sent
8905 to application (otherwise application doesn't know that it is for
8906 channel (library gets it from packet's Destination ID)).
8908 * Added silc_client_remove_from_channels into client library to
8909 remove a client from all channels it has joined to. Used when
8910 received SIGNOFF notify from server. Added also new function
8911 silc_client_replace_from_channels to replace old ID entry with
8912 new ID entry on all channels. Used when received NICK_CHANGE
8915 * Fixed ID Cache list handling in silc_idlist_get_client in
8916 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8917 to get (or query) client by ID.
8919 * Updated TODO list.
8921 * Added connection authentication status message defined by the
8922 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8923 support for these into the code in client and server side.
8925 * Added generic function silc_client_send_command to send any command
8926 with variable argument list. Application should use this function
8927 to send commands if the command functions provided by the library
8928 does not suite for the application's user interface needs.
8930 * Added new `failure' client operation. Application is notified about
8931 received failure packet if client is executing a protocol. In this
8932 case the protocol's execution has failed.
8934 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8935 is required by the protocol.
8937 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8938 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8941 * Added status flag to SilcSKE object to indicate realtime status
8942 of the SKE protocol.
8944 * Application receives now exactly same command reply arguments as
8945 the library receives from server. However, if ID is received the
8946 corresponding ID entry is returned to the application (eg. Client
8947 ID is mapped to correct SilcClientEntry entry and that is returned).
8948 Changed command_reply client operation due to this change.
8950 * Changed all ID's in commands and in command replys as ID Payloads.
8951 Change affected both client and server side codes.
8953 All ID's sent in SILC network (with execption of ID's in SILC
8954 Packet header) are sent in ID Payload to support variable length
8957 * Server now notifies nick changes and notifies all clients on
8958 the channels about the new nickname (about the new Client ID,
8961 * Implemented CMODE command to change channel modes. Supports all
8962 channel modes defined by the protocol specs except ban and invite
8963 lists. (Also, private channel key mode is supported but support for
8964 setting private channel key in client is missing, thus, this mode
8965 has no effect on client side (except that server requires that the
8966 client uses private channel key and normal channel traffic does not
8969 Also, invite mode works per se, but INVITE command does not work
8970 yet correctly, so you can set channel as invite only channel but
8971 inviting clients to the channel does not work (it is yet to be
8972 thought what's the best way to do it).
8974 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8975 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8976 Implemented CUMODE command to change user's mode on the channel.
8977 Supports all modes defined by the protocol specs.
8979 * Added NAMES command reply to return users modes on the channel.
8981 * Removed unnecessary and slow ciphers from lib/silccrypt.
8983 * Set SO_KEEPALIVE option to connection sockets by default.
8985 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8987 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8988 redefined the Notify Payload into protocol specs.
8990 * Added silc_id_payload_parse_id to get ID directly from raw
8993 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8995 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8996 accept searching by Client ID as well.
8998 * Added support for LEAVE and SIGNOFF notify types in client library.
9000 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
9001 to parse ID Payload from raw data.
9003 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9005 * Added flags parameter into silc_ske_assemble_security_properties
9006 function in lib/silcske/silcske.[ch].
9008 * Changed notify client operation to fit better for notify messages
9009 sent by server. The notify payload received from server is now
9010 passed to the application (after parsing it to SilcNotifyPayload).
9011 It is application's responsibility to retrieve the arguments
9012 from the payload and show the message the way it wants. The message
9013 sent by server is implementation specific.
9015 * Changed public keys to comply with the protocol specification.
9016 Old public keys are not supported anymore and are not compatible.
9018 * Removed nickname from Channel Payload as the latest draft removed
9019 it. The client must resolve the nickname from the NAMES command
9020 reply received when it joined the channel.
9022 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
9024 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9026 * Fixed some errors in protocol specification drafts.
9028 * Created lib/silccore/silcnotify.c to implement Notify Payload
9029 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
9030 generic payloads described by protocol specifications. The file
9031 includes implementations for ID Payload and Argument Payload.
9033 * Changed Command Payload implementation to use the new Argument
9034 Payload. Changed command_xxxx_payload to command_payload_xxxx
9035 to comply with SILC coding conventions.
9037 * Added suppport for Argument Payload handling in Notify Payload
9038 implementation as protocol requires it. Added the new support
9039 into server and client lib as well.
9041 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9043 * Added support for multiple nicknames on same channel. [n] is
9044 added locally to the nickname if there are more than one same
9045 nicknames on the channel.
9047 * Server now sends all nicknames that matched WHOIS request.
9048 Client also shows the list received from server.
9050 * Added TOPIC command to client side. User can now set and show
9051 current topic on channel.
9053 * Added MOTD command to client and server. Also, server sends the
9054 motd when client connects to the server.
9056 * Changed version strings to comply ISO 8601.
9058 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9060 * Fixed protocol error handling in client library. It should now
9061 cope even if the SKE fails for some reason.
9063 * Made new protocol specification drafts for submitting to IETF.
9065 * Implemented TOPIC command to server in silcd/command.c.
9067 * Added two new notify types into lib/silccore/silcnotify.h:
9068 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
9069 notify nickname change and topic setting/change on a channel.
9071 * API change of command_reply operation in client library. The
9072 application gets now the status type received from server as well.
9074 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9076 * Removed the function just added to lib/silcutil/silcschedule.[ch].
9078 * Cras fixed and optimized the packet handling even further and
9079 it should work now. Minor change to the prototype of function
9080 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
9082 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9084 * Added new function into lib/silcutil/silcschedule.[ch]:
9085 silc_schedule_with_fd to select() a specified fd. The function
9086 returns after timeout expires or data arrives or goes. The
9087 function is used by packet routines to wait that all data is
9088 received from network.
9090 * Fixed data reading from network in lib/silccore/silcpacket.c.
9091 The code now assures that all data is read from the fd and then
9092 continues packet processing. This was a bug fix since the code
9093 used to drop some data in some circumstances.
9095 * Added new function into lib/silcclient/client.[ch]:
9096 silc_client_start_key_exchange to start key exchange after
9097 connection has been established to server. The code internally
9098 now uses this funtion but its main purpose was to provide it
9099 for applications that perform their own connecting. After
9100 application has created a connection it merely calls this
9101 function to start the key exchange between client and server.
9102 The library takes care of everything else after that.
9104 Updated also lib/silcclient/README to explain the usage of
9107 * Do not send to application information that connection has
9108 been established. Application gets notified it by connect
9111 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9113 * Applied cras's patch to add silc_schedule_one function. The
9114 function runs scheduler once and returns.
9116 * Fixed the scheduler after cras messed it up. The timeout
9117 handling works now as it's supposed to work.
9119 * Added into lib/silccore/ silcnotify.h to include notify
9120 message types support. Changed silc_server_send_notify*
9121 functions, in server.[ch], to support those new notify types.
9122 Added the support for the notify types into client library,
9123 as well. Added new notify client operation into ops.h in
9126 * Changed silc_server_packet_send_to_channel to send normal
9127 packets instead of just channel message packets. The function
9128 is now used to send the notify packets to channels. It is not
9129 used to send channel message packets anymore, as server never
9132 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
9133 va_arg()s as it seems to require it nowadays. I guess, if SILC
9134 is compiled with older va_arg() the new code should work anyway.
9136 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9138 * Splitted core library. Core library (lib/silccore) includes
9139 now only SILC protocol specific core (and common) components.
9140 Created new utility library (lib/silcutil) that includes more
9141 generic purpose stuff. The stuff for util library was taken
9142 from the old core library. This was minor and easy split.
9144 * Created SILC Client Library (lib/silcclient) that includes
9145 implementation of the SILC client without user interface. This
9146 was major move from silc/ directory. The code has been changed
9147 so that it is transparent towards the user interface. The
9148 silc/ directory includes now the same user interface as before
9149 and it uses the new client library. Read lib/silcclient/README.
9150 Basicly, the client library performs everything else related
9151 to SILC except user interface handling. Also, configuration
9152 files are considered to be part of user interface and library
9153 does not handle them.
9155 This change also changed a lot of structures, function naming etc.
9156 Most important change was that SilcClientWindow object was
9157 renamed to SilcClientConnection in the client library. Created
9158 also new file lib/silcclient/ops.h. Also added new files
9159 silc/local_command.[ch] and silc/client_ops.[ch].
9161 All these changes were made to make it easier for user interface
9162 designers to create what ever user interface for the SILC client
9165 It is also expected that the server will be moved to lib
9166 directory as well and SILC Server Library will be created;
9167 sometimes in the future.
9169 * Removed Local commands from lib/silccore/silccommand.h as
9170 they are application specific and new client library does not
9171 handle any of those anymore.
9173 * Several functions moved to lib/silcutil/silcutilc.[ch] from
9174 old client implementation in silc/.
9176 * Added support for callback functions in SILC_LOG_* macros.
9177 Application can now set its own callbacks that will be called
9178 instead of using the default functions that will always print
9179 the debug messages to stderr (or stdout). Also, debugging can
9180 now be disabled by setting silc_debug to FALSE and re-enabled by
9181 setting it to TRUE. Note, that logging will still work even
9182 if debugging is disabled.
9184 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
9185 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
9186 silc_log_reset_debug_callbacks.
9188 * To enable debugging in silc client one must give now -d
9189 option on command line.
9191 * Changed silc_schedule_init to automatically allocate task queues
9192 if they are not allocated before calling it.
9194 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9196 * Added GMP 3.1 into math library.
9198 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9200 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
9201 a channel in SILC network. The packet is used by servers and
9202 routers to notify other routers that user has left a channel.
9203 This little feature was missing until now. Added the feature
9204 to protocol specification as well.
9206 Added functions: silc_server_send_remove_channel_user and
9207 silc_server_remove_channel_user into server.[ch].
9209 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
9210 lib/silccore/silcpacket.h. However, they are not implemented
9213 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9215 * Fixed joining to a channel and sending channel messages
9216 between server and router. The channel message sending should
9217 now work inside a cell.
9219 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9221 * Fixed the private message sending between server and router.
9222 The private message sending should now work inside a cell.
9224 * Added silc_server_replace_id into server.[ch] to replace
9225 existing ID in the SILC network.
9227 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
9228 and silc_idlist_replace_server_id into idlist.[ch] in server.
9230 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9232 * Fixed the server to server connections. Server can again now
9233 connect to router. Router to router connections probably does
9236 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9238 * Added dynamic protocol registering support. Now protocols can
9239 registered and unregistered on the fly. Patch by cras.
9241 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9243 * Added lib/contrib directory to hold routines that some platforms
9244 don't have but are needed by SILC.
9246 * Added getopt.c, getopt1.c and getopt.h from GNU C library
9247 into lin/contrib to provide getopt() and getopt_long() for
9248 those who don't have it.
9250 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9252 * Added AWAY command to client. When away message is set and
9253 client receives a private message packet the client automatically
9254 replies to the sender with the away message.
9256 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
9257 bug seemed to be the cause of recent problems when compiling
9260 * Added version detection support to SKE protocol specification
9261 and added the new changes to the SKE implementation as well.
9262 There were other minor changes in the SKE protocol as well.
9264 Many changes in lib/silcske/silcske.[ch] and in
9265 lib/silcske/payload.[ch].
9267 * Added ^U functionality, clear input line. Patch from cras.
9269 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9271 * Mainly small bugfixes on core library. Fixed some debugging
9272 logging and buffer overflow in silclog.c.
9274 * Updated config.sub and config.guess on the distribution tree.
9276 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9278 * Added command lagging support in server. Client may execute
9279 commands now only once in two seconds.
9281 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9283 * Optimized packet reception. MAC computation and checking is now
9284 also more optimized. A lot previously duplicated code is now
9285 used as generic by both client and server.
9287 * Fixed key pair generation in clientutil.c
9289 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9291 * Added into lib/silccore/silcbufutil.[ch] new function;
9292 silc_buffer_realloc.
9294 * Moved generic packet sending/encryption functions to
9295 lib/silccore/silcpacket.[ch] from client and server. Some
9296 rewriting of the functions.
9298 * Moved all generic packet reception/decryption functions to
9299 lib/silccore/silcpacket.[ch] from client and server. The
9300 packet processing is now much cleaner in both client and server.
9301 These were major changes in both client and server.
9303 * Created many common functions in server to do packet sending.
9304 Previously code were duplicated a lot, this has been removed
9307 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9309 * Rewrote major parts of the ID cache system. Don't know
9310 whether it is better now or not but at least the API is more
9313 * Major rewrite on ID cache stuff on client because of the ID
9314 cache API changes. Added idlist.c to client.
9316 * Also major rewrite on ID cache stuff on server as well.
9317 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9318 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9319 in hand, instead they are all put into the ID cache system now.
9320 All server_idlist_* routines uses ID cache now instead of
9321 traversing its own lists (those lists does not exist anymore).
9322 SilcIDList though still exists. Also, SilcXXXEntry's are
9325 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9327 * Finally made the SKE implementation compliant to the protocol
9328 specification. All mp integers are now binary encoded as
9329 opposed being HEX encoded.
9331 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9334 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9335 functions: silc_[encode/decode]_pem. Also added function
9336 silc_encode_pem_file to PEM encode with newlines ('\n') for
9339 * SILC public keys are now encoded either PEM or binary. Same
9340 option is for private keys as well. By default private keys
9341 are binary encoded and public keys PEM encoded. Silly HEX
9342 encoding were removed.
9344 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9345 function to create fingerprints.
9347 * Fixed a bug in SHA1; does not change the original data anymore.
9349 * Partly implemented INFO command on client and server side.
9350 Fixed CLEAR command. Changes to SERVER command; show current
9351 server(s) when giving command without arguments. Added
9352 VERSION command to client.
9354 * Added check to server that unregistered connections cannot
9355 execute commands (unless it is specificly allowed).
9357 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9359 * Fixed screen refresh.
9361 * Fixed channel joining bug from client. On some circumstances
9362 client tried to join to a channel it had already joined.
9364 * Added public key verification process into client's protocol.c.
9365 The client now verifies the public key from user and saves
9366 it into ~./silc/serverkeys/ directory.
9368 Added into: clientutil.[ch]: silc_client_verify_server_key.
9370 * Changed SKE protocol's silc_ske_initiator_finish function
9371 to accept callback function that verifies the received public
9372 key. Removed old silc_ske_verify_public_key function.
9374 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9376 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9377 silc_pkcs_private_key[_data]_set.
9379 * Made the password and public authentication more cleaner in
9380 server's protocol.c.
9382 * Removed historic and obsolete protocol `channel_auth' from
9383 both client and server.
9385 * Removed wrong way of sending command status messages from
9386 server to client in server's command.c. The old way violated
9387 protocol specification.
9389 Changes to silccore/silccommand.[ch]: removed
9390 silc_command_encode_status_payload -> not needed anymore,
9391 changed silc_command_encode_payload_va to accept extra
9392 argument on variable argument list. The argument type must
9393 now be provided to the function. Also, added new function:
9394 silc_command_encode_reply_payload_va which is same as
9395 normal command_encode_payload_va except command status type
9396 is provided as extra argument.
9398 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9400 * Added ~./silc directory handling. The directory includes the
9401 public and private keys for the client.
9403 Added silc_client_check_silc_dir, silc_client_create_identifier
9404 and silc_client_load_keys.
9406 * Implemented SILC protocol compliant public key. Added public
9407 and private key saving to and loading from files.
9409 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9410 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9411 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9412 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9413 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9415 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9416 silc_pkcs_load_[public/private]_key.
9418 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9420 * Added silc_server_get_route (route.[ch]) to get connection
9421 data for the fastest route for given ID.
9423 * Implemented INVITE command on client and server. The command
9424 were re-defined in the SILC Protocol Specification and the
9425 implementation now complies with the specification.
9427 * Implemented PING command on client and server.
9429 * Implemented NAMES command on client and server. The server side
9430 supports currently only normal server not router server yet.
9431 Some changes to NAMES definition in SILC protocol specification.
9433 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9435 * Implemented LEAVE command on client and server.
9437 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9438 again. This change was made to the protocol as well. Server
9439 should not violate the protocol specification anymore.
9441 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9443 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9444 was tested. SOCKS4 was not but should work anyway.
