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

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

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

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

192 * Rewrote WHOIS, WHOWAS and IDENTIFY commands in the server.
193 Added server_query.[ch] which provides one interface for
194 querying information using all three commands.
196 * Changed all "typedef unsigned char" in core library to
199 Sat Sep 21 21:36:45 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

208 * Resumed client packet handling from server put the resumed
209 client on wrong list on router and caused the client not
210 be present on the network anymore. Now fixed to put the
211 client to correct list. Affected file silcd/packet_receive.c.
213 Wed Sep 18 15:13:48 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
215 * Various cleanup in error message output in config parsing code
216 and in server init code. Fixed error log files containing
217 too many newlines ('\n') in some situations. Affected files are
218 silcd/serverconfig.c, silcd/silcd.c, and silcd/server.c.
220 Wed Sep 18 10:51:23 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
222 * Use the reverse lookupped hostname in client internals
223 instead of one user provided us as remote server name.

226 Mon Sep 16 12:02:54 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
228 * Added 'app_context' to silc_schedule_init. It is an
229 application specific context that is delivered to application
230 in task callback functions. Affected files are
231 lib/silcutil/silcutil.[ch].
233 * The hb_context in SilcSocketConnection is not freed
234 automatically anymore (application must free it). Freeing
235 it automatic is inconsistent. Affected files are
236 lib/silcutil/silcsockconn.[ch].
238 Sun Sep 15 22:16:19 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
240 * Added support for removing explicitly added client connections
241 in rehash and closing the client connections if they were

244 * Added support for aborting automatically pending commands
245 that never receives the reply (to avoid memory leaks).
246 Added also silc_server_command_pending_timed to set the
247 specific timeout for pending command. Affected files are
248 silcd/command[_reply].[ch].

257 file lib/silcutil/silcutil.[ch].
259 * Added STATS command to client library and Irssi SILC client.
260 Patch provided by Ville Räsänen <ville.rasanen@iki.fi>.
262 Wed Sep 11 09:22:00 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
264 * Assure that channel key is set before sending it. May
265 crash server otherwise. Affected file silcd/packet_send.c.
267 Tue Sep 10 09:50:08 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
269 * Assure that endless loop cannot happen with detached client
270 resolving on normal server. Added idlist status
271 SILC_IDLIST_STATUS_RESUME_RES. Affected files are
272 silcd/idlist.h and silcd/packet_receive.c.
274 Mon Sep 9 12:18:18 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
276 * Incoming file transfer request cannot use same session as
277 the sending session. This can happen when sending file to
278 yourself. Crashed the client on quit. Affected file
279 lib/silcclient/client_ftp.c. Bug #24.
281 Sun Sep 8 18:39:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
283 * Implemented the draft-riikonen-precense-attrs draft and
284 the Attribute Payload into the lib/silccore/silcattrs.[ch].
286 Sun Sep 8 13:13:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
288 * Distribute the SERVER_SIGNOFF notify also to local backup
289 routers from the primary router. The backup router may not
290 have the signing of local server directly connected and need
291 to know about the signoff. Affected file silcd/server_util.c.
293 * Use the primary router as the origin of the locally connected
294 server when it is disconnecting from the backup router since
295 that's where it really is coming from. Now the clients from
296 the disconnecting server are removed correctly and "shadow"
297 clients are not left to the backup router. Affected file
300 Sat Sep 7 22:26:50 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
302 * If normal server is standalone and found existing but disabled
303 channel, do not re-create the channel since it creates
304 duplicate same channels. Affected file silcd/server.c.
306 * Added anonymous client connections support to server. New
307 "anonymous" configuration option to ConnectionParams section
308 added. If set to true, the username and hostname information
309 of the client will be scrambled and anonymous user mode is
310 set automatically to the user. Affected files are
311 silcd/serverconfig.[ch], silcd/packet_receive.c and server.c.
313 Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
315 * In JOIN notify handling, mark that the cache entry of the
316 client cannot be expired. Can cause crashes on normal
317 server (asserts client->channels). Affected file is
318 silcd/packet_receive.c.
320 * From now on distribution versions are used as protocol versions
321 instead of by default using the Toolkit base version as protocol
322 version. Affected file prepare.
324 * Do not set the locally resolved hostname for local client
325 entry but take what server sends. This way the real hostname
326 is showed in WHOIS for yourself. Affected file is
327 lib/silcclient/idlist.c and lib/silcclient/client.c.
329 * Resolve local info with IDENTIFY when connecting to server.y
331 Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
333 * Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
334 for implied search (not needed on platforms which has native
335 pthreads library). Use --without-pthreads to disable threads.
336 Affected file is configure.in.pre
338 * Fixed --with-iconv on platforms which need to bypass (broken)
339 native iconv(). Affected file is configure.in.pre
341 Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
343 * Moved -C option parsing in Irssi SILC client at same time
344 as other options. The UI was initialized earlier and caused
345 problems on command line. Bug #16. Affected file is
346 irssi/src/silc/core/silc-core.c.
348 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
350 * Added global variable silc_log_timestamp that tells silclog
351 wether to print or not the timestamp in the logging files.
352 Affected file lib/silcutil/silclog.[ch].
354 * Added silcd configuration option Timestamp in the Logging
355 section. Affected file silcd/serverconfig.[ch],
356 doc/example_silcd.conf.in.
358 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
360 * Fixed fingerprint checking to check for entirely empty
361 fingerprint instead of two first bytes when determining
362 if it is set. Bug #18. Affected file silcd/command.c.
364 * Fixed duplicate PKCS name registering to not allow it.
365 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
367 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
369 * Conditionalize non-gcc compiler optimizations for various
370 platforms, enable those commented out. Cleanups.
371 Affected file lib/silcmath/mpi/configure.in
373 Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>
375 * silc_rng_exec_command() left zombie processes if command
376 didn't generate any output. Affected file
377 lib/silccrypt/silcrng.c
379 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
381 * Rewrote iconv checking, introduce --with-iconv for systems
382 which rely on libiconv. Check if iconv() provided by libc
383 is good enough, otherwise demand libiconv. Affected file
386 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
388 * Search for ldopen() also in libc. This enables SIM support
389 on *BSD systems. Based on patch from Alex Zepeda. Affected
390 file configure.in.pre
392 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
394 * Don't call AM_CONDITIONAL conditonally for SILC_THREADS.
395 This fixes prepare on *BSD systems. Affected file
398 Sun Aug 4 15:55:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
400 * More fixed for not having purge timeout for global clients
401 that are on channel. Affected files silcd/command_reply.c
404 * Fixed the rekey protocol to work with backup router connections.
405 Rekey packets are now allowed on disabled connections as
406 well. Affected files silcd/packet_send.c and server.c.
408 * Do not switch to be as backup router when shutting down and
409 closing the primary connection. Affected file silcd/server.c.
411 * Fixed memory leaks in backup router deleting. Added
412 silc_server_backup_free to free all data during shutdown of
413 server. Affected files silcd/server_backup.[ch].
415 Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
417 * Do not process commands if the sock->user_data is NULL.
418 Affected file silcd/command.c.
420 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
422 * Fixed buffer overflow and security problems (loosing bits
423 in CFB encryption) in SILC RNG. Problems reported by
424 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
426 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
428 * Added yet more checks that client is not expired on global
429 list if it is on channels. Affected file is
430 silcd/command_reply.c.
432 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
434 * Merged c0ffee's MIME signal patch which adds support for
435 sending also MIME messages in Irssi SILC Client, and handling
436 received MIME messages in a signal (and perhaps doing something
437 to non-textual MIME messages).
439 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
441 * Fixed pending command deletion in server and client library
442 to check the whole list instead of breaking after first found.
443 The affected files are silcd/command.[ch] and
444 lib/silcclient/command.[ch].
446 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
448 * Return NO_SUCH_CHANNEL error in USERS for channel that is
449 secret or private, otherwise it's possible to find out
450 whether a secret channel exists or not. Affected file
453 * If CMODE change fails during the mode setting, assure that
454 the old mode mask is set for the channel back. Affected
455 file silcd/command.c.
457 * Fixed passphrase saving on +a channel on normal server
458 after successful JOIN command. Affected file silcd/command.c.
460 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
462 * Remove server/router operator privileges in DETACH command,
463 since it's possible to resume to server where these
464 privileges would not be allowed for the client. Affected
465 file silcd/command.c.
467 * Do not set to wait for backup in rehash of the server.
468 Affected file silcd/server.c.
470 * Do not check listener sockets when counting how many
471 socket connections we have. Affected file is
474 * Do not announce disconnected clients that are remaining
475 in history (for WHOWAS). This is because SIGNOFF notify
476 for these has been sent earlier already. Affected file
479 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
481 * Buffer overflow with CUMODE command's mode->mode character
482 conversion. Reported by Ville Räsänen. Affected file
483 lib/silcutil/silcutil.c.
485 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
487 * Allow heartbeat packets to go disabled connections anyway.
488 Affected files silcd/server.c and silcd/packet_send.c.
490 * Do not broadcast New Channel packets with List flag set
491 in the packet to backup routers. The router must check
492 for the correctness of the packets before sending them.
493 It is possible that router will have enforce Channel ID
494 change and this would cause desync in the backup router.
495 Affected file silcd/packet_receive.c.
497 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
498 are handled in list parsing. They are not list packets
499 anymore. Affected file silcd/packet_receive.c.
501 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
503 * Stop waiting for backup router through the timeout, not
504 directly after backup router has arrived. Affected file
507 * Do not re-create channel keys and send them when removing
508 clients in server shutdown. Affected files are
509 silcd/server_internal.h and silcd/server_util.c.
511 * Notify distribution to backup routers was missing from
512 the silc_server_send_notify_dest function which caused
513 desyncing problems with backup router. Affected file is
516 * The client's channel removing was working wrong on
517 backup router. It assumed that it doesn't know global
518 information but backup router does know. For this reason
519 it could remove channel when it wasn't supposed to do that.
520 Affected file silcd/server.c and silcd/server_util.c.
522 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
524 * Stop for a couple seconds after badkup router has become
525 primary router. Affected file silcd/server.c.
527 * Added silc_server_remove_servers_by_server, which is used
528 to remove servers originated from some other server. Also
529 clients of those servers can be removed too. Affected file
530 silcd/server_util.[ch].
532 * When removing clients after a server has signed of remove
533 also all servers behind that server (unless they are known
534 to be available locally), and send SERVER_SIGNOFF for each
535 of the server separately. Also the signed off clients are
536 sent now separately per signed off server. The affected files
537 are silcd/server.c and silcd/server_util.[ch].
539 * All servers added with silc_idlist_add_server must always
540 have both "router" and "connection" pointers set. Otherwise,
541 bad server entries may be left around in the cache.
542 Affected file silcd/command_reply.c.
544 * Do not create the channel key in NEW_CHANNEL packet
545 processing if the channel is empty. Affected file
546 silcd/packet_receive.c.
548 * Completed backup router support for standalone routers.
549 Supports also servers in the cell that do not use the backup
552 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
554 * Fixed a bug in silc_string_regexify which did not add '^'
555 at the start of each string, and thus the matching was
556 not explicit. For example ban list iikone@*!*@* would
557 match also "priikone", which is wrong, it would have to be
558 *iikone@*!*@* to match also "priikone". Affected
559 file lib/silcutil/unix/silcunixutil.c.
561 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
563 * Enable all local server connections before updating client
564 caches when we've become backup router. Otherwise, signoff
565 packets may not reach the clients. Affected files are
566 silcd/server.c and silcd/server_util.[ch].
568 * Fixed a bug in version string parsing which could crash
569 the program with specially formatted version string.
570 Bug reported and patch provided by Ville Räsänen. Affected
571 file lib/silcutil/silcutil.c.
573 * Handle the disconnection immediately when DISCONNECT
574 packet is received in server. Affected file silcd/server.c.
576 * Primary router now waits a short time (10 seconds) for
577 backup router connection before accepting any other
578 connection (except local). Affected file silcd/server.c,
581 * Fixed a crash in client libary in NICK_CHANGE notify when
582 NICK_CHANGE arrived for client entry we are resolving
583 currently. Affected file lib/silcclient/client_notify.c.
585 * Call the sconn->callback completion even if error had
586 occurred. Start reconnecting always if connection to
587 primary router fails during backup router protocol.
588 Affected files silcd/server.c and server_backup.c.
590 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
592 * Added functions silc_server_send_opers and
593 silc_server_send_opers_notify to send packets stricly
594 to operators. Added macro SILC_SERVER_SEND_OPERS macro
595 to send variable argument notify to operators.
596 Affected files silcd/packet_send.[ch] and silcd/server.h.
598 * Removed UMODE rights checking with UMODE_CHANGE notify.
599 Affected file silcd/packet_receive.c.
601 * Server/router operator now receives notify when network
602 switches to backup router and when it resumes the use of
603 primary router. Affected file silcd/server.c and
604 silcd/server_backup.c.
606 * Fixed the updating of client information after backup
607 resuming protocol is over; update all except local clients
608 to the new primary router. The affected file is
611 * Added support for closing active connections in rehash
612 that were unconfigured by the user. Supports currently
613 closing server and router connections. Affected file
616 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
618 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
620 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
621 is NULL since seems that on some platforms NULL is allowed
622 and on some it's not. Fallback encoding is used instead.
623 Affected file lib/silcutil/silcstrutil.c.
625 * Fixed statistics updating for incoming server connection
626 which could cause problems when re-connecting. Affected
629 * Preliminary backup router support for standalone router
630 added. Affected files in silcd/.
632 * Mark server connections in backup router disabled before
633 and after backup protocol. Affected file is
634 silcd/server_backup.c.
636 * Added support for reconnecting to remote server connection
637 even if the protocol fails, and if the configuration wants
638 us to keep trying to connect anyway.
640 Server connection is not allowed to backup router if
641 backup router does not have connection to primary router yet.
643 Affected file is silcd/server.c.
645 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
647 * Added silc_client_udpate_server function to update changed
648 server info. Affected file lib/silcclient/idlist.[ch].
650 * Added check for server entries that are being resolved when
651 notify is received. If being resolved, handle the received
652 notify only after it's resolved so that all notifys are
653 handled in same order as received from the server.
655 Added similar resolver check to channel entries. Every
656 notify that cause resolving of any information that affects
657 channel entry marks the channel entry in waiting state.
658 After whatever resolving is over the waiters are signalled
659 and only then the notifys are handled in the same order
660 as delivered from the server.
662 Affected files are lib/silcclient/idlist.[ch], and
665 * Fixed KILLED notify handling in normal server. Affected
666 file silcd/packet_receive.c.
668 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
669 is locally connected, or was locally connected (but may
670 be detached and connection is not active). Added also
671 SILC_IS_LOCAL for checking this status. Affected files
672 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
673 silcd/server.c and silcd/server_internal.h.
675 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
677 * Don't send or handle TOPIC_SET if topic is already set and
678 is same as being set. Affected files silcd/command.c and
679 silcd/packet_receive.c.
681 * Fixed CMODE change rights checking to work correctly when
682 removing modes by operator. Affected file is
685 * Fixed some handling with New Channel packet in router and
686 fixed some CMODE_CHANGE notify handling in server and router.
687 Affected file is silcd/packet_receive.c.
689 * Changed "disconnect" client operation to include the
690 reason of the disconnection and optional disconnection
691 message. Affected file lib/silcclient/silcclient.h.
693 * Made the compilation of lib/contrib/ stuff conditional.
694 Affected files configure.in.pre, lib/contrib/Makefile.am.
696 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
698 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
699 to the sender of the notify too, to avoid situation where two
700 notifys are in the network at the same time going to oppsite
701 directions. Affected file silcd/packet_receice.c.
703 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
705 * Delete the client from channel even if the cilent->id is
706 NULL. It was possible that client was deleted without
707 removing from channels (theoretically at least). Affected
708 file silcd/server.c and silcd/server_util.c.
710 * Free the client data too when resuming is not successful.
711 Affected file silcd/packet_receive.c.
713 * Merged some code from c0ffee's silc-plugin. Affected files
714 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
716 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
717 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
718 to the primary router connection, the other one returns
719 TRUE if packet must be broadcasted to network.
721 * All notifys that are destined to primary router (to network)
722 are now automatically sent to backup routers even if the
723 router is standalone (and has backup router). Affected files
726 * Added --without-irssi and --without-silcd configuration
727 options for disabling the compilation of these applications.
728 Affected file configure.in.pre and prepare.
730 Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
732 * Implemented SILC_STRING_BMP and SILC_STRING_UNIVERSAL for
733 UTF-8 encoding and decoding. Added also new encodings
734 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
736 Added also SILC_STRING_LANGUAGE which is language and charset
737 specific encoder and decoer for those platforms that support
738 iconv(). It can convert the UTF-8 to and from the locale
739 specific character set.
741 Affected file lib/silcutil/silcstrutil.[ch].
743 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.
745 * Added function silc_get_command_name to the file
746 lib/silcutil/silcutil.[ch].
748 * Improved the server debug output a bit. Affected files are
751 Wed Jun 19 17:46:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
753 * Save the channel passphrase when received succesful JOIN
754 command reply from router, on normal server. Otherwise
755 joinig +a channels from normal server is not possible.
756 Affected file silcd/command.c.
758 * Fixed a bug in TOPIC_SET notify handling. The notifier
759 may be other than client too, like server or channel.
760 It expected it to always be only client and ignored the
761 notify. Affected file silcd/packet_recieve.c.
763 * Removed some (unnecessary) debug printing from
764 lib/silccore/silcid.c and lib/silccore/silcargument.c.
766 * Do not force CMODE_CHANGE when server is announcing new
769 Router announces stuff only after server reannounces channel
770 after CHANNEL_CHANGE notify.
772 These fixes optimizes the announcing procedure, and perhaps
773 fixes some problems too. Affected file silcd/packet_receive.c.
775 * Fixed SERVER_SIGNOFF sending to local clients. It was
776 totally broken and sent the notify to all local clients,
777 instead of only to those that was on same channel as the
778 signing off clients. Affected file silcd/server_util.c.
780 * Added -D option to server. It can be used to give debug
781 level. The levels are from 0 - 99, and are predefined for
782 smooth server debugging. (see silcd.c for the predefined
783 levels). Affected file silcd/server.c.
785 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

791 Tue Jun 18 17:14:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
793 * When authenticating as founder during JOIN command, check
794 that the one authenticating becomes the only founder on the
795 channel. Affected file silcd/command.c.
797 * Better checking for founder mode setting when CUMODE_CHANGE
798 notify is received. Affected file silcd/packet_receive.c.
800 * Close all connections when shutting down the server by sending
801 DISCONNECT packet. Close all listeners too when shutting
802 down the server. Affected file silcd/server.c.
804 * Handle DISCONNECT packet correctly in client library by
805 calling the "disconnect" client operation. Affected file
806 lib/silcclient/client.c.
808 * Handle local errors correctly during resuming. Affected
809 file lib/silcclient/client.c.

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

877 The one that authenticated will become founder and anyone
878 else is demoted. Affected file silcd/command.c.
880 * Added error printing of any error that has occurred during
881 any command in client library. Affected file is
882 irssi/src/silc/core/client_ops.c.

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

1389 * Redefined the Status Payload to include now two 8 bit fields,
1390 instead of one 16 bit field. This now makes it possible to
1391 send list of errors. Updated the protocol specs and the code
1392 in core library, client library and server. Protocol TODO #1.
1393 Affected files are lib/silccore/silccommand.[ch],
1394 lib/silcclient/command_reply.[ch], silcd/command.c,

1424 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1426 * Added STATS command to the protocol after all, to return
1427 various statistical information about the network. It can
1428 be used by clients to retrieve statistical information, and
1429 servers may use it to to fetch cell and network wide
1430 statistics from router. Updated the protocol specs and
1431 implemented it to the server. Protocol TODO #16.

1437 * The LIST command reply in client libary now adds new channel
1438 entry if the returned channel doesn't exist yet in cache,
1439 and returns the channel entry to the application in the
1440 command_reply client operation. Affected file is
1441 lib/silcclient/command_reply.c.
1443 * Changed the channel message payload's MAC generation to
1444 include the IV in the MAC as well. This way all relevant
1445 parts of the channel message payload are authenticated also
1446 with the channel message MAC (and not only by packet MAC).
1447 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1448 Affected file is lib/silccore/silcchannel.c.
1450 * Fixed the SKE to save the remote version, since the

1521 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1522 generic reply to a generic request (REQUEST flag), and
1523 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1524 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1525 to define the payload for DATA flag. Added the flags to
1526 the implementation. Protocol TODO #9. Affected file is
1527 lib/silccore/silcchannel.h.
1529 Changed the client library to return the message length

1573 * Some client implementations quit network by doing first LEAVE
1574 and then immediately SIGNOFF (like Bombyx). We now do check
1575 after a short time after LEAVE notify and check whether the
1576 client is still valid after LEAVE, and if not we remove it from
1577 cache. Affected file is lib/silcclient/client_notify.c.
1579 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1581 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1582 it's good not to have security holes here.
1584 * Fixed a negative refcount situtuation for the config context.
1585 Affected file is silcd/serverconfig.c.
1587 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1589 * ROBOdoc documented lib/silcutil/silcutil.h.
1591 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1593 * Optimized even more the SilcPacketContext structure. Now
1594 totally saved 16 bytes of memory per context after optimization.
1595 Affected files are lib/silccore/silcpacket.[ch].
1597 * Made strict checks for valid SILC IDs. Affected file is
1598 lib/silccore/silcid.c.
1600 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1602 * Changed the object argument for silc_cipher_register,
1603 silc_hash_register, silc_hmac_register and silc_pkcs_register
1604 to const. Affected files are lib/silccrypt/silccipher.[ch],
1605 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1607 * Changed the silc_get_username and silc_get_real_name to
1608 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1610 * Fixed the Irssi SILC Client to use the silc_get_username and
1611 silc_get_real_name insted of glib routines since the glib
1612 routines only corrupt stack. Fixes the Irssi SILC to work in
1613 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1615 * Fixed the Irssi to not use g_get_home_dir since it crashes
1616 or returns garbage on cygwin and corrupts stack. Added function
1617 get_home_dir to Irssi routines. Affected files are
1618 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1620 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1622 * Made some structure optimizations. SFTP memory FS MemFSEntry
1623 entry structure. Optimized SilcTask structure. Optimized
1624 SilcPacketContext structure.
1626 Affected files lib/silcsftp/sftp_fs_memory.c,
1627 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1629 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1631 * And yet again reverted back the config thing since Johnny
1632 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1635 * Fixed memory leaks from config object. Affected files are
1636 silcd/serverconfig.[ch].
1638 * Added support for adding new connections to the server in rehash.
1639 After rehash they take effect.
1641 Added support for changing the maximum allowed connections in
1642 rehash. The number can grow but going smaller is not supported.
1644 Added function silc_server_num_sockets_by_remote to the
1645 silcd/server_util.[ch].
1647 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1649 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1651 * Added preliminary checking during config parsing for a valid
1652 public/private key and removed further checks in the code.
1653 Affected files are silcd/serverconfig.[ch], server.c.
1655 * Moved functions silc_server_drop() and silc_server_daemonise()
1656 from server.c to silcd.c since they are stricly related to
1657 the application activity.
1659 * Reverted a small part of the automatic ref/unref since
1660 it caused a double unref in some situations. Affected
1661 files are silcd/silcd.[ch], server.c, serverconfig.c.
1663 * Added some .cvsignore files in the lib directory.
1665 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1667 * Fixed silc_net_gethostbyaddr to correctly resolve by
1668 address. Affected file lib/silcutil/silcnet.c.
1670 * Fixed the notify relaying to client. The HMAC to be used
1671 with relayed packets ws wrong and caused decryption failure
1672 at the client end. Affected file is silcd/packet_receive.c.
1674 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1676 * Created new branch silc_protocol_1_0_branch.
1678 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1680 * Changed the silc_server_config_* routines to be SilcServer
1681 independent. They are now officially application specific code
1682 and not part of generic server implementation. Affected files
1683 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1685 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1687 * Added automatic referencing of config context in the
1688 silc_server_config_alloc, and automatic unreferencing in the
1689 silc_server_config_destroy. Affected files are
1690 silcd/serverconfig.[ch], silcd/silcd.c.
1692 * Fixed the silc_log_quick handling in the logging routines.
1693 It didn't log quickly when it was TRUE. Affected file is
1694 lib/silcutil/silclog.c. Also the flush delay was set even
1695 if it was 0 in config file. Affected file is
1696 silcd/serverconfig.c.
1698 * Added support for changing key pair of the server in rehash.
1699 Affected file silcd/server.c.
1701 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1703 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1704 too early, before getting the channel entry. Affected file
1705 is silcd/packet_receive.c.
1707 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1709 * Added functions silc_server_config_[ref/unref], these are used
1710 to prevent that the config object is destroyed.
1712 No longer directly affect global variables silc_log_quick and
1713 silc_log_delay, they are first cached inside the config object
1714 and then applied with silc_server_config_setlogfiles().
1716 silc_server_config_set_defaults() is now internal to
1717 serverconfig.c, there are no reasons to show this internal stuff
1720 Affected files are silcd/serverconfig.[ch].
1722 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1723 fprintf's to stderr, since some code may be executed again after
1724 the server went into the background. Affected files are
1727 * Added rehash support. Added function silc_server_rehash() that
1728 will perform all the basic tasks of the rehashing procedure.
1730 * Added command line option `-x, --hexdump'. This will enable the
1731 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1732 The option `--hexdump' implies `--debug'.
1734 * Fixed a bad bug in the logging APIs (silcutil library) where
1735 the application would crash after calling silc_log_reset_all().
1737 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1739 * Fixed the KICKED notify handling in client library to
1740 correctly remove the channel and all entries from the
1741 channel when I was kicked. This bug crashed the client.
1743 Fixed yet another but in KICKED notify handling to remove
1744 the kicked client correctly from the channel.
1746 Affected file is lib/silcclient/client_notify.c.
1748 * Fixed a minor bug in looking up correct client entry
1749 in KICKED notify in server. Affected file is
1750 silcd/packet_receive.c.
1752 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1753 sources correctly to distribution. Fixes --with-gmp option.
1755 * Removed the manual rehashing from ID Cache, and changed it
1756 to use the SILC Hash Table's auto rehash feature. Affected
1757 file is lib/silccore/silcidcache.c.
1759 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1761 * Fixed a bug in the silc_client_nickname_format function that
1762 handles the multiple same nickname formatting. Two clients
1763 with same nickname caused problems after the first one left
1764 and rejoined. It didn't format the nickname correctly.
1765 Affected file is lib/silcclient/idlist.c.
1767 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1769 * Don't change the topic if olod topic is same as new one.
1770 Affected file is silcd/packet_receive.c.
1772 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1774 * Added cross-reference support to the SILC Documentation
1775 generator. All types across all HTML files are now cross-
1776 referenced. Affected files util/robodoc/generator.c and
1777 scripts/silcdoc/silcdoc.
1779 * Added file lib/silcutil/silctypes.h to include all the
1780 arithmetic type definitions and some macros. Removed
1781 includes/bitmove.h and moved macros to silctypes.h.
1783 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1785 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1787 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1789 * Added `type' argument to silc_id_payload_parse_id function which
1790 now returns the type of the ID to the sent pointer. Affected
1791 file is lib/silccore/silcid.[ch].
1793 * Added check for CMODE_CHANGE notify type that mode change is
1794 allowed by the sender. Affected file silcd/packet_receive.c.
1796 * Added check for CUMODE_CHANGE notify type that mode change is
1797 allowed by the sender. Affected file silcd/packet_receive.c.
1798 Added the ID type as CUMODE_CHANGE notify type as argument
1799 to the `notify' client operation. Affected files are
1800 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1802 * Added function silc_client_add_server to the client library.
1803 Added support for resolving also channel and server info when
1804 received unknown entity in notify packet. Affected files are
1805 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1807 * Added function silc_command_get_status to return the command
1808 status from the command reply's argument payload. Affected files
1809 are lib/silccore/silccommand.[ch].
1811 * Added check for KICKED notify type that the kicking is
1812 allowed by the client. Affected file silcd/packet_receive.c.
1814 * Created function silc_get_input which can be used to get input
1815 (echo on or off) from user on command line. Affected files are
1816 lib/silcutil/silcutil.[ch].
1818 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1820 * Optimized silc_server_packet_relay_to_channel function.
1821 Added new function silc_channel_message_payload_encrypt which
1822 can be called directly if channel message payload needs to
1823 be encrypted and is already encoded (no need to call _encode
1824 function). Packet relaying is now done by router without any
1825 extra memory allocations. Affected files are
1826 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1827 silcd/packet_send.c.
1829 * Fixed the INVITE notify handling. It took wrong arguments
1830 as invite list and invite delete. Affected file is
1831 silcd/packet_receive.c.
1833 * Added check for TOPIC_SET notify type that the topic change is
1834 allowed by the client. Affected file silcd/packet_receive.c.
1836 * Added check for INVITE notify type that inviting is allowed by
1837 the client. Affected file silcd/packet_receive.c.
1839 * Changed the silc_server_client_on_channel to return the
1840 SilcChannelClientEntry as well. Moved the function
1841 silc_server_check_cmode_rights to server_util.[ch].
1842 Affected files are silcd/server_util.[ch], silcd/command.c.
1844 * Added function silc_server_check_umode_rights to check whether
1845 changing client's user mode is allowed. Added check for
1846 UMODE_CHANGE notify type that the umode change is allowed
1847 by the client. Affected files are silcd/server_util.[ch],
1848 silcd/packet_receive.c and silcd/command.c.
1850 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1852 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1853 ID length. It ignored that ID can be IPv6 based as well.
1854 Affected file lib/silccore/silcpacket.h.
1856 * Fixed the silc_id_id2str and silc_id_str2id to take the
1857 IPv6 address offset's into consideration. Affecte file is
1858 lib/silccore/silcid.c.
1860 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1862 * Fixed the internal Unix scheduler functions to check for
1863 NULL context they may receive. The affected file is
1864 lib/silcutil/unix/silcunixschedule.c.
1866 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1868 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1869 can specify different directory with --home command line
1870 parameter. Affected files irssi/src/silc/core/client_ops.c,
1873 * SILC-specific commands aren't now executed if the active server
1874 isn't of SILC-type, so there won't be problems with having
1875 IRC and SILC protocol support in same client. Affected files
1876 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1879 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1881 * Improved the signal support in SILC Schedule. Added new
1882 function silc_schedule_signal_call which is used by application
1883 to mark a signal to be called. It is now safe to perform
1884 any kind of tasks in signal callbacks since it is guaranteed
1885 that the application specified signal callback is called
1886 after the signal is over. Affected files are
1887 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1889 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1891 * Added `name' field to SilcChannelPrivateKey to represent
1892 application given name for the key. Moved also the context from
1893 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1894 Added the `name' argument also to the function
1895 silc_client_add_channel_private_key.
1897 Added function silc_client_current_channel_private_key to set the
1898 current channel private key in use.
1900 Added "change" command to KEY command which can be used to change
1901 the current channel private key. Bound the command also to
1902 alt+K (Alt+Shift+k).
1904 Also affected files lib/silcclient/client_channel.c,
1905 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1907 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1909 * Added silc_rng_get_byte_fast function in to the
1910 lib/silccrypt/silcrng.[ch].
1912 * Changed the interface of silc_packet_assemble and the
1913 silc_packet_send_prepare. If silc_packet_assmble is now
1914 called the application does not call silc_packet_send_prepare
1915 because the library will call it automatically. These
1916 interfaces now also return a reference to the outgoing buffer
1917 which includes the assembled packet, which the application can
1918 use to encrypt the packet.
1920 Affected files are lib/silccore/silcpacket.[ch],
1921 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1922 silcd/packet_send.c, server_backup.c and packet_receive.c.
1924 * Fixed a packet sending bug on very high load, where outgoing
1925 packet queue wasn't handled correctly and packets got corrupted.
1926 Affected files are lib/silcutil/*/silc*sockconn.c,
1927 lib/silcclient/client.c and silcd/server.c.
1929 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1931 * Added macro SILC_PACKET_DATALEN which can be used during
1932 packet assembling to check whether the data to be added to
1933 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1934 len is truncated until it fits it.
1936 Added checks for maximum length of channel message payload and
1937 private message payload also.
1939 Added checks for maximum packet length in server and in
1942 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1943 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1944 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1945 lib/silcclient/client_prvmsg.c.
1947 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1949 * Added silc_server_packet_queue_purge call to the
1950 silc_server_disconnect_remote to assure that all data in the
1951 queue before disconnecting is sent to the network. Affected
1952 file silcd/server.c.
1954 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1956 * Added the deleting of server's own ID cache entry to the
1957 silc_server_free function. Free also everything else that
1958 has been allocated in silc_server_init. The affected file
1961 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1963 * Added functions silc_parse_version_string, silc_version_to_num,
1964 and silc_ske_parse_version to parse SILC protocol style version
1965 strings. Affected files lib/silcutil/silcutil.[ch] and
1966 lib/silcske/silcske.[ch].
1968 * Added new configuration params: version_protocol, version_software
1969 and version_software_vendor to specify what version the remote
1970 host must at least be to be able to connect to server. The vendor
1971 string can be regex matched too. Added new function
1972 silc_server_connection_allowed to check maximum number of allowed
1973 connections, and allowed versions for incoming connections.
1974 Affected files are silcd/server.c, server_util.[ch] and
1977 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1979 * Added preliminary support for signals in scheduler. The
1980 signals we care about are now blocked always when the scheduler
1981 is locked. This way we can synchronise the use of signal with
1982 scheduler. It is guaranteed that when signal occurs the scheduler
1983 is not locked, and thus new tasks can be safely added to the
1986 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1987 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1988 Added new platform specific routines
1989 silc_schedule_internal_signals_[un]block and
1990 silc_schedule_internal_signal_[un]register.
1992 Added new functions to SILC Schedule API:
1993 silc_schedule_signal_[un]register. Each signal that application
1994 is going to use should be registered to the scheduler.
1996 Affected files are lib/silcutil/silcschedule.[ch],
1997 lib/silcutil/*/silc*schedule.c.
1999 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2001 * Check for unauthenticated client and server in the
2002 silc_server_new_client and silc_server_new_server functions.
2003 Affected file silcd/packet_receive.c.
2005 * Added function silc_string_is_ascii to check whether given
2006 string is 7-bit ASCII string. Affected files are
2007 lib/silcutil/silcutil.[ch].
2009 * Added function silc_id_is_valid_server_id into the
2010 silcd/serverid.c and added checking for valid Server ID's in
2011 silc_server_new_server. The Server ID must always be based
2012 on the server's public IP address.
2014 * Added logging of DISCONNECT packet message in the server.
2015 Affected file silcd/server.c.
2017 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2019 * Changed all library interfaces that use Global RNG to also
2020 accept SilcRng as argument. Affected files are
2021 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
2022 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
2023 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
2024 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
2025 lib/silccrypt/rsa.c.
2027 * Added function silc_pkcs_generate_key to the
2028 lib/silccrypt/silcpkcs.[ch] for applications so that they
2029 don't need to do pkcs->pkcs->init calls anymore.
2031 * Remove SilcSocketConnection from the SFTP API since it really
2032 wasn't needed there. The application has the information
2033 saved in its contexts anyway and the SFTP layer doesn't need
2034 know about it. Affected files lib/silcsft/silcsftp.h and
2035 lib/silcsftp/sftp_[server/client].c.
2037 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
2038 The SilcSimContext is not SilcSim.
2040 * Fixed possible buffer overflows in silc_id_render in the
2041 lib/silcutil/silcutil.c.
2043 * On EPOC the global crypto module lists are not used at all
2044 in the crypto library. Added support for using the constant
2045 algorithm list on EPOC. Affected files are
2046 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
2049 * Fixed the handling of third parameter of KICKED notify, since
2050 it was mistakenly updated to SILC Protocol 1.0 even though it
2051 is to be included in 1.1. Since it is not in 1.0 it is not
2052 mandatory, and this fix now handles it only if it is provided,
2053 and it is not error if it is not provided. Affected file
2054 lib/silcclient/client_notify.c.
2056 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2058 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
2059 client. Affected file irssi/src/silc/core/client_ops.c.
2061 * Merged with Irssi 0.8.4 from irssi.org CVS.
2063 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2065 * Check for valid socket connection in client entries before
2066 sending any messages. Fixes a crash, but doesn't fix some
2067 other underlaying bug that is lurking there. Affected
2068 file silcd/packet_send.c.
2070 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
2072 * $usermode, $cumode and $cumode_space expandos shouldn't do
2073 anything with non-SILC server records. Affected file
2074 irssi/src/silc/core/silc-expandos.c

2093 file lib/silcutil/silcutil.[ch].
2095 * Added support for specifying multiple public keys for Client
2096 connection section in server configuration file. This makes it
2097 possible to accept multiple public keys from same host, or to
2098 make a section that accepts any incoming host, and have the
2099 accepted public keys listed in the section.
2101 Added functions silc_sever_[find/get]_public_key, added the
2102 support for this actually to all connection sections but only

2214 old name went against naming convention. Applications now
2215 include "silcclient.h" instead of "clientlibincludes.h".
2216 Removed includes/clientlibincludes.h, it is redundant now.
2218 * Renamed includes/version.h to silcversion.h.
2220 * Added really preliminary support for OS/2 into the util
2221 library. Only thread & mutex API is implemented, others
2222 are still to be implemented. Created the lib/silcutil/os2/

2256 * Added `user_count' to the SilcChannelEntry which now tells the
2257 number of users on the channel. The user count is now saved
2258 in normal server of global channels as well. Affected files
2259 silcd/server.c, idlist.h, packet_receive.c and command.c.
2261 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
2262 include file utility functions.

2278 the SKE interface a bit.
2280 * Fixed padding problem in PKCS#1. The padding was not actually
2281 random since the random number generator was used incorrectly.
2282 This security bug affects only when encrypting with PKCS#1, and
2283 it is not currently used at all in SILC. SILC only use signing
2284 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

2347 Affected files irssi/src/silc/core/silc-core.c,
2348 irssi/src/fe-text/silc.c.
2350 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2352 * Added new configuration options and blocks:
2353 keepalive_secs, reconnect_count, reconnect_interval,
2354 reconnect_interval_max, reconnect_keep_trying and

2369 the connection configuration object from the SilcServerConnection
2370 object instead of finding it during the connecting phase.
2371 Added the configuration object to SilcServerConnection struct.
2372 Affected files silcd/server_internal.h, server.c.
2374 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2376 * Add the client on channel after it was resolved at the
2377 channel message receiving, and it was not already on the
2378 channel. Affected file lib/silcclient/client_channel.c.
2380 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2400 public key is set. If not set, public key is preferred.
2401 This has effect only when being initiator (responder will try
2404 Added support for authentication with passphrase and public key
2405 at the same time. The passphrase is tried first always since
2406 it is faster to check.
2408 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2410 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2456 * Fixed the file transfer's key agreement payload to include
2457 zero port also if the hostname is NULL because it could not
2460 Call file transfer monitor callback now also if error occurs
2461 during key agreement protocol.
2463 Changed the silc_client_file_send interface to return the
2464 SilcClientFileError instead of session id. The session ID
2465 is returned into pointer provided as argument.

2482 file lib/silcutil/silclog.c.
2484 * Fixed the channel message payload decryption in the function
2485 silc_channel_message_payload_decrypt to not modify the original
2486 buffer before it is verified that the message decrypted
2487 correctly. Otherwise, next time it is called with correct
2488 channel key it won't encrypt since the payload is corrupted.
2489 Affected file lib/silccore/silcchannel.c.
2491 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2504 the table with foreach callback. The current entry may
2505 become invalid in the callback but it was referenced after
2506 the callback returned.
2508 Do not allow auto rehashing of hash table during the
2509 silc_hash_table_foreach operation, for same reasons as it is
2510 not allowed for SilcHashTableList. Affected files are
2511 lib/silcutil/silchashtable.[ch].
2513 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

2537 * Fixed a bug in hash table tarversing. While the hash table
2538 is traversed with SilcHashTableList the table must not be
2539 rehashed. It is now guaranteed that auto rehashable tables
2540 are not rehashed while tarversing the list. Also defined that
2541 silc_hash_table_rehash must not be called while tarversing
2542 the table. Added function silc_hash_table_list_reset that must
2543 be called after the tarversing is over. The affected files are
2544 lib/silcutil/silchashtable.[ch].
2546 * Changed all hash table traversing to call the new
2547 silc_hash_table_list_reset in server and in client library.
2549 * Added function silc_client_on_channel to return the
2550 SilcChannelUser entry if the specified client entry is joined
2551 on the specified channel. This is exported to application as
2552 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

2560 * Fixed the WHOWAS command's reply sending to support the
2561 lists correctly. Affected file silcd/command.c.
2563 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2565 * When sending JOIN command to router for processing the
2566 sender's old command identifier was not saved back to the
2567 sender's command context, fixed now. The affected file is
2570 * Create the key in JOIN command of the router did not return
2571 the channel key, added check for this. Affected file is
2574 * Fixed a channel ID update bug in JOIN command reply. Do
2575 not directly upgrade the ID but call the function
2576 silc_idlist_replace_channel_id if the ID was changed.
2577 Affected file silcd/command_reply.c.
2579 * Fixed memory leaks from command calling if it would fail.
2580 Affected file silcd/command.c.

2595 with server connections. Later this will be configurable
2596 in config file after new config file is done. Affected file
2599 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2601 * Fixed a crash in server related to channel announcements.
2602 Affected file silcd/server.c.
2604 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2606 * Fixed memory leaks in silc_server_create_new_channel*
2607 functions. Affected file silcd/server.c.
2609 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2610 which ID was changed. This way the router will send the
2611 user list for the channel again, and server won't be in
2612 desync in some rare circumstances. Affected file is
2613 silcd/packet_receive.c.
2615 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2617 * Check for NULL socket pointer in the function
2618 silc_server_packet_send_to_channel_real. Affected file
2619 silcd/packet_send.c.
2621 * Fixed the BAN notify handling to correctly remove ban
2622 list. Affected file silcd/packet_receive.c.
2624 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2626 * Fixed some header addition to Toolkit distribution in
2627 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2629 * Added lib/silcclient/client_ops_example.h as an template
2630 file for application programmers to quickly start using
2631 the SilcClientOperation functions in their application.
2632 Updated the lib/silcclient/README as well to tell about this
2633 nice file made available.
2635 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2637 * Call silc_server_remove_from_channels when removing client
2638 entry when NO_SUCH_CLIENT_ID was received. Affected file
2639 is silcd/command_reply.c.
2641 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2643 * Added server & router operator statistics updating. Affected
2644 file silcd/packet_receive.c and silcd/command.c.
2646 * Fixed the SERVER_SIGNOFF notify handling on normal server
2647 not to save the history information for clients. Same was
2648 fixed earlier in remove_clients_by_server function, but not
2649 here. Affected file silcd/packet_receive.c.
2651 * Raised the default connection-retry count from 4 to 7 in
2652 server. Affected file silcd/server.h.
2654 * Cancel any possible reconnect timeouts when we start the
2655 key exchange. Affected file silcd/server.c.
2657 * Do not reconnect on connection failure when SCONNECT was
2658 given. Affected files silcd/server.[ch].
2660 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2662 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2664 * Fixed the NICK command to always give the unformatted
2665 nickname to the one giving the NICK command. If unformatted
2666 nickname is cached already it will be formatted and the
2667 local entry will always get the unformatted nickname.
2668 Affected file lib/silcclient/idlist.c.
2670 * Fixed some double frees from client library commands.
2671 Affected file is lib/silcclient/command.c.
2673 * Fixed CUMODE command in server to assure that no one can
2674 change founder's mode than the founder itself, there was a
2675 little bug. Affected file silcd/command.c.
2677 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2679 * Removed the SilcClientCommandDestructor from the client
2680 libary, it is not needed anymore. Affected files are
2681 lib/silcclient/silcapi.h, command[_reply].[ch],
2682 client_notify, idlist.c.
2684 * Fixed GETKEY command to first resolve client, and then
2685 resolve the server only if the client was not found, instead
2686 of resolving both at the same time. Affected file is
2687 lib/silcclient/command.c.
2689 * Added silc_client_start_key_exchange_cb and lookup the
2690 remote hostname and IP address before starting the key
2691 exchange with server. The affected file is
2692 lib/silcclient/client.c.
2694 * The server's public key is now saved using the IP address
2695 of the server and not the servername for the filename.
2696 The hostname public key filename is checked as an fall back
2697 method if the IP address based filename is not found.
2699 Fixed the GETKEY command to save the fetched server key
2700 in correct filename.
2702 Print the remote server's hostname now when new key is
2703 received during connection process. Affected file is
2704 irssi/src/silc/core/client_ops.c.
2706 * Return always our own public key to the client if it asks
2707 for it with GETKEY command. Affected file silcd/command.c.
2709 * Removed the use_auto_addr variable from default config
2710 file since it was in wrong section. Affected file is
2713 * Fixed TOPIC_CHANGE notification to not route it when it
2714 was sent using silc_server_send_notify_to_channel function.
2715 Affected file silcd/command.c.
2717 * Fixed silc_server_send_notify_kicked to send the kicker's
2718 Client ID also, it was missing. Affected files are
2719 silcd/command.c, silcd/packet_send.[ch].
2721 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2723 * Do not save client history information in SERVER_SIGNOFF.
2724 Fixes the bug in normal server that it does not detect
2725 the client becoming valid after the server becomes back
2726 online. Affected file silcd/server_util.c.
2728 * Added `sock_error' field into the SilcSocketConnection
2729 context. When error occurs during socket operation (read
2730 or write) the error is saved. Added also new function
2731 silc_socket_get_error to return human readable socket error
2732 message. Affected files are lib/silcutil/silcsockconn.[ch],
2733 lib/silcutil/unix/silcunixsockconn.c, and
2734 lib/silcutil/win32/silcwin32sockconn.c.
2736 * The server now prints the socket error message in the
2737 signoff for client. Affected file silcd/server.c.
2739 * Fixed the `created' channel information sending from router
2740 to server in JOIN command. Checks now whether the channel
2741 really was created or not and set it according that.
2743 Fixed the JOIN command to use the client entry's current
2744 ID during the joining procedure instead of the one it sent
2745 in the command (it is checked though), since it can change
2746 between the packet processing and command processing, and
2747 would just case unnecessary pain in the client end. Affected
2748 file silcd/command.c.
2750 * Fixed a channel key payload sending to use correct channel
2751 ID when the server was forced to change the channel's ID by
2752 router. Router sent the key payload with the old Channel ID.
2753 Affected file silcd/packet_receive.c.
2755 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2757 * Call silc_server_save_channel_key only if the key payload
2758 was provided in the JOIN command's command reply. Affected
2759 file silcd/command_reply.c.
2761 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2763 * Fixed silc_mp_sizeinbase to return the value correctly with
2764 MPI. Affected file lib/silcmath/mp_mpi.c.
2766 * Fixed the stop_server signal to correctly stop the scheduler
2767 and gracefully stop the server when SIGTERM or SIGINT signals
2768 are received. Affected file silcd/silcd.c.
2770 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2772 * Simple handling of TERM and HUP signals. Also added some log
2773 flushing call around. Affected file is
2776 * Fixed small bugs in silclog.c. Now buffering output will take
2777 effect after 10 seconds since startup: This will ensure that
2778 no important startup messages are lost. Also output redirection
2779 will preserve original format ([Date] [Type] message).
2780 Affected file is lib/silcutil/silclog.c.
2782 * Added two options to the config file, in the logging section:
2783 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2784 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2786 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2788 * Do not print the warning about log files not being initialized
2789 more than once to avoid excess logging. Affected file is
2790 lib/silcutil/silclog.c.
2792 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2793 the SIM copying in make install in Makefile.am.pre.
2795 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2797 * Rewritten silclog APIs. Globally interesting changes follows:
2798 silc_log_set_files() changed to silc_log_set_file().
2799 silc_log_set_callbacks() changed to silc_log_set_callback().
2800 ROBOdoc documented silclog header file.
2801 SilcLogCb now returns bool to wether inihibit the default
2802 handler or not (to keep the old behaviour return always TRUE).
2803 The new APIs should also fix the problem of the
2804 silcd_error.log file that was written in the current directory.
2807 Log files streams will remain opened after silc_log_set_file()
2808 call, means less CPU usage notably on high traffic servers.
2809 File streams are now full buffered, and flushed to the disk
2810 every 5 minutes, lesses HD activity and CPU usage.
2811 Messages can be redirected, allowing admins to configure
2812 one single logfile for all server messages.
2813 the silc_log_quick global variable to activate fast-logging.
2814 Affected files lib/silcutil/silclog.[ch]
2816 * Changed some code to conform new silclog APIs. Affected
2817 files are doc/example_silcd.conf.in, silcd/server.c
2818 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2821 * Fixed a memory leak that could occur in some situations.
2822 Affected file silcd/serverconfig.c.
2824 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2826 * Added the silc_client_del_client to remove the client from
2827 all channels as well. Affected file lib/silcclient/idlist.c.
2829 * Fixed the client library to correctly remove the client
2830 from all channels when the client entry is being destroyed.
2831 Affected file lib/silcclient/client_notify.c, command.c.
2833 * Added auto-nicking support to the client library. If the
2834 applicatio now sets client->nickname it will be sent to the
2835 server after connecting by the library. This way for example
2836 SILCNICK (or IRCNICK) environment variables will have effect
2837 and always change the nickname automatically to whatever
2838 it is wanted. Affected file lib/silcclient/client.[ch].
2840 * Renamed silc_server_command_bad_chars to the
2841 silc_server_name_bad_chars and moved it to the
2842 silcd/server_util.[ch]. Added also new function
2843 silc_server_name_modify_bad to return nickname that
2844 includes bad characters as new nickname without those
2845 bad characters. This check and modify is now used in
2846 silc_server_new_client when the username is initially set
2847 as nickname, so it must be checked to be valid nickname.
2848 Affected file silcd/packet_receive.c.
2850 * The nickname length is now taken from the packet for real
2851 and not trusted to strlen() since it clearly can return
2852 wrong length for nickname including bad characters. This
2853 also applies to channel names. Affected file silcd/command.c.
2855 * Removed the lib/silcsilm/modules directory. Modules are now
2856 compiled into the lib/silcsim. Fixed the copying of the
2857 modules to follow symbolic links in Makefile.am.pre.
2859 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2861 * Fixed silc_string_regexify list creation. Fixes bugs with
2862 BAN and INVITE commands in server. The affected file is
2863 lib/silcutil/unix/silcunixutil.c.
2865 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2867 * Removed the command destructor entirely from the server's
2868 command and command reply routines. It is not needed, and
2869 its usage was buggy and caused crashes. Affected files are
2870 silcd/command[_reply].[ch].
2872 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2874 * Cancel protocol and NULL sock->protocol if timeout
2875 occurred during protocol. Affected file silcd/server.c.
2877 * Cancel protocol timeouts always before calling the final
2878 callback, to assure that after final callback is called
2879 no other state will be called for the protocol anymore.
2880 Affected file silcd/protocol.c.
2882 * Print error log if incoming connection configuration could
2883 not be found. Affected file silcd/server.c.
2885 * Fixed JOIN command to correctly save the founder mode
2886 to the client on normal SILC server, when the channel
2887 was created by the router. Affected file silcd/command.c.
2889 * Fixed LIST command (hopefully) to send correct reply
2890 packets. Affected file silcd/command.c.
2892 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2894 * The silc_packet_receive_process now returns FALSE if the
2895 read data was invalid packet, and TRUE if it was ok.
2897 The server now checks that if unauthenticated connection
2898 sends data and its processing fails the server will close
2899 the connection since it could be a malicious flooder.
2901 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2903 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2905 * Make sure the warning about error opening a log file is
2906 printed only once and not everytime it fails (produces
2907 too much useless log). Affected file lib/silcutil/silclog.c.
2909 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2911 * Made the silc_server_daemonise() function more readable.
2912 Affected file silcd/server.c.
2914 * Pid file is now optional, the user may comment it out from
2915 the config file. Removed define SILC_SERVER_PID_FILE, we
2916 don't need a default any longer. Affected file
2917 configure.in.pre, lib/Makefile.am.pre.
2919 * Make some use of the pid file. The server now dies at startup
2920 if it detects a valid pid file on his path. The server would
2921 die anyway in this circumstance, because of the bind() failure.
2922 Affected file silcd/silcd.c.
2924 * No longer compiling lib/dotconf.
2926 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2928 * Fixed JOIN command parsing not to crash. Affected file
2929 lib/silcclient/command.c.
2931 * Fied the NICK_CHANGE notify to add the new client entry
2932 even it is resolved. This removes an <[unknown]> nick
2933 thingy bug in the client. Affected file is
2934 lib/silcclient/client_notify.c.
2936 * Do not try to allocate 0 bytes (efence does not like it)
2937 in lib/silccore/silccomand.c when encoding payload.
2939 * Do not take IRCNICK as nickname in Irssi SILC client since
2940 it is not possible to set nickname before hand connecting
2941 the server (TODO has an entry about adding auto-nicking
2944 * Changed the silc_server_command_pending to check whether
2945 there already exists an pending entry with the specified
2946 command, command identifier and pending callback. This is
2947 to fix IDENTIFY and WHOIS related crashes that may register
2948 multiple pending commands with same identifier. Affected
2949 file silcd/command.c.
2951 * Fixed the server to reconnect to the router even if it
2952 was already reconnecting and EOF was received. This to
2953 fix a possibility that the server wouldn't ever try to
2954 auto-reconnect to the router. Affected file silcd/server.c.
2956 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * Fixed the server's password authentication to use the
2959 length of the locally saved password, and not the one
2960 sent in the packet. Affected file silcd/protocol.c.
2962 * Fixed same password authentication problem in the
2963 Authentication Payload handling routines in
2964 lib/silccore/silcauth.c.
2966 * Yet another password authentication problem fixed with
2967 channel password handling in silcd/command.c.
2969 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2971 * If first character of string in silc_parse_userfqdn is '@'
2972 then do not parse it. Affected file is
2973 lib/silcutil/silcutil.c.
2975 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2977 * Fixed minor bug in IDENTIFY command reply sending, which
2978 caused various weird problems during JOIN when it was
2979 resolving names for users. Affected file silcd/command.c.
2981 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2983 * Fixed the IDENTIFY command reply sending to chech better valid
2984 clients. It was possible to send incomplete list of replies.
2985 Affected file silcd/command.c.
2987 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2989 * Added silc_client_command[s]_[un]register functions now to
2990 dynamically register the commands in client library. Removed
2991 the static table of commands. This allows the client library
2992 to call commands without causing the application to know about
2993 what commands library has called.
2995 Removed the INFO command reply kludge to detect when the command
2996 was called by library. Now library use its own command reply
2997 function for INFO command.
2999 Added function silc_client_command_call to call a command.
3000 Application can use it to call command, not access the structure
3003 Now all commands that are sent by the client library (not
3004 explicitly sent by application) use own command reply functions.
3006 Affected files around lib/silcclient/ and in
3007 irssi/src/silc/core/.
3009 * Fixed the WHOIS command reply sending to chech better valid
3010 clients. It was possible to send incomplete list of replies.
3012 Fixed the WHOIS and IDENTIFY to send the request to router
3013 if normal server did not do it and did not find any results.
3015 Affected file silcd/command.c.
3017 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3019 * Moved the internal data from SilcClient context into its
3020 own file, not accesible to application. Affected files
3021 lib/silcclient/client.h and lib/silcclient/client_internal.h,
3022 and other files in client library.
3024 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3026 * Added doc/examples installation target in Makefile.am.pre.
3029 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3031 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
3032 commands the found client entry will be removed from the
3033 cache, after notifying application about the error. Affected
3034 file lib/silcclient/command_reply.c.
3036 * Changed the /MSG to check for exact nickname user gave, and
3037 not let `nick' match `nick@host' if it is only one found. Now,
3038 user must type the exact nickname (like nick@host2) even if
3039 there are no more than one same nicks found. This is to avoid
3040 a possibility of sending nickname to wrong nickname since
3041 `nick' could match `nick@host'. Affected file is
3042 irssi/src/core/silc-servers.c.
3044 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3046 * Do not print "you are now server operator" or similar when
3047 giving /away command. Affected files are
3048 irssi/src/silc/core/client_ops.c, silc-servers.h.
3050 * Made the silc_server_command_pending_error_check to send
3051 the same command reply payload it received back to the
3052 original sender of the command. This way all arguments
3053 that was received by the server will be received by the
3054 client too. Affected file silcd/command.c.
3056 * Added the silc_idcache_add to return the created cache entry
3057 to a pointer. Affected file lib/silccore/silcidcache.[ch].
3059 * Add global clients to expire if they are not on any channel.
3060 This is because normal server will never know if they signoff
3061 if they are not on any channel. The cache expiry will take
3062 case of these entries. This is done by normal servers only.
3063 The affected files are silcd/command_reply.c,
3064 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
3066 * If server receives invalid ID notification for WHOIS or
3067 IDENTIFY and the ID exists in the lists, it is removed.
3068 Affected file silcd/command_reply.c.
3070 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
3071 in client then client entry that it matches is searched and
3072 the nickname is printed on the screen for user. Affected
3073 file irssi/src/silc/core/client_ops.c.
3075 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3077 * Use cache entry expire time in the LIST command reply to
3078 purge old entries from the cache after the LIST command
3079 reply has been received. This way we don't have non-existent
3080 entries in the cache for too long. Affected file is
3081 silcd/command_reply.c.
3083 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3085 * If we are normal server, and we've not resolved client info
3086 in WHOIS or IDENTIFY from router, and it is global client,
3087 we'll check whether it is on some channel. If it is not
3088 then we cannot be sure about its validity and will resolve it
3089 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
3090 file silcd/command.c.
3092 * Search channel by name (if possible) rather than by ID
3093 in IDENTIFY command's command reply. Affected file is
3094 silcd/command_reply.c.
3096 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3098 * Distribute to the channel passphrase in CMODE_CHANGE notify.
3099 Updated specs and implemented it. Affected file silcd/command.c,
3100 silcd/packet_send.c and silcd/packet_receive.c.
3102 * Implemented the <founder auth> payload handling in the JOIN
3103 command. If provided all conditions for channel joining
3104 except requirement to provide correct passphrase can be
3105 overrided by the channel founder. Updated the protocol specs.
3106 Affected file silcd/command.c.
3108 Added support for founder auth in JOIN command in client
3109 library. Fixed the parsing of the JOIN command now to support
3110 all options as they should be. The affected file is
3111 lib/silcclient/command.c.
3113 * Optimized the WHOIS and IDENTIFY commands to send the request
3114 to router only if it includes nicknames or other names. If
3115 they include only IDs then check the local cache first before
3116 routing. Affected file is silcd/command.c.
3118 * Added channels topic announcements. Affected file is
3119 silcd/packet_receive.c and silcd/server.c.
3121 * Fixed the silc_server_send_notify_topic_set to really destine
3122 the packet to channel. Affected file silcd/packet_send.c.
3124 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
3125 library. Affected file lib/silcclient/client_notify.c.

3147 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3149 * Update the client entry context in the ID cache after
3150 nick change. Affected file lib/silcclient/command.c.
3151 Fixes the CUMODE command when regaining founder privileges,
3152 and a little WHOIS problem.
3154 * Fixed silc_net_gethostbyname to correctly call the
3155 inet_ntop. Affected file lib/silcutil/silcnet.c.
3157 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3159 * Added IPv6 support checking to the configure.in.pre, added
3160 also --enable-ipv6 option to override the check. Affected
3161 file configure.in.pre.
3163 * The silc_thread_create now calls the start function
3164 directly if threads support is not compiled in. Removes
3165 ugly #ifdef's from generic code. Affected files are
3166 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
3168 * Added silc_net_gethostby[name/addr]_async to asynchronously

3187 * Fixed LIST command reply sending in server. Affected file
3190 * Server now sends the kicker's client ID in the KICK notify
3191 to the kicked client. Affected file silcd/command.c.
3193 * The client library now parses the kickers client ID and
3194 UI displays it. Affected files lib/silcclient/client_notify.c
3195 and irssi/src/silc/core/silc-channels.c, module-formats.c.
3197 * Made all payload parsing function prototypes consistent.
3198 They all take now const unsigned char * and uint32 pair as
3199 the payload data instead of SilcBuffer. Changes all around
3200 the source tree. Other unsigned char* -> const unsigned char*
3201 changes around the tree as well.
3203 * Optimized SFTP client and server packet sending not to
3204 allocate new buffer for each packet but to recycle the
3205 first allocated buffer. Affected files are
3206 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
3208 * Optimized the SFTP client to use SilcList instead of
3209 SilcDList for requests, because it is faster. Affected file
3210 is lib/silcsftp/sftp_client.c.
3212 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
3213 into lib/silccore/silcid.[ch].
3215 Renamed silcpayload.[ch] into silcargument.[ch].
3217 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3219 * If client entry is deleted with active key agreement
3220 session, abort the session.
3222 The silc_client_abort_key_agreement now calls the completion
3223 callback with new SILC_KEY_AGREEMENT_ABORTED status.
3225 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
3228 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3230 * Don't use __restrict in older GCC's. Affected file is
3231 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
3233 * silc_net_localhost now attempts to reverse lookup the
3234 IP/hostname. Affected file lib/silcutil/silcnet.c.
3236 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
3237 command. It can be used to gain founder privileges at
3238 the same time when joining the channel.
3240 Defined that the SILC_NOTIFY_TYPE_KICKED send the
3241 kicker's client ID as well. Updated protocol specs.
3243 Defined that the server must send SILC_COMMAND_IDENTIFY
3244 command reply with error status to client who sent
3245 private message with invalid client ID.
3247 Updated the protocol specification.
3249 * Added silc_server_send_command_reply to send any
3250 command reply. Affected file silcd/packet_send.[ch].
3252 * Added silc_id_payload_encode_data to encode ID payload
3253 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
3255 * The server now send IDENTIFY command reply with error
3256 status if client ID in private message is invalid. Affected
3257 file silcd/packet_receive.c.
3259 * Save the server key file with server's IP address in
3260 the filename instead of hostname. The affected file is
3261 irssi/src/silc/core/client_ops.c.
3263 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3265 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
3268 * Added libtool support for compiling shared objects in
3269 lib/silcsim. Affected file configure.in.pre and
3270 lib/silcsim/Makefile.am. Original patch by cras.
3272 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3274 * Pid file configuration, and server's config file fixes
3275 patch by toma. Updated CREDITS file.
3277 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3279 * Fixed silc_client_channel_message to not try to decrypt
3280 the message twice if it resolved the destination client
3281 information. This could cause of dropping one channel
3282 message. Affected file lib/silcclient/client_channel.c.
3284 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3286 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3287 lib/silcclient/client.c. This function is used when the SILC
3288 Client is run under some other scheduler, or event loop or
3289 main loop. On GUI applications, for example this may be
3290 desired to used to run the client under the GUI application's
3291 main loop. Typically the GUI application would register an
3292 idle task that calls this function multiple times in a second
3293 to quickly process the SILC specific data.
3295 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3297 * Fixed silc_server_drop() for dropping the supplementary
3298 groups as well, this could cause a security hole on some
3301 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3303 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
3306 * Write PID file after dropping privileges. Added -F option
3307 to run server on foreground. A patch by debolaz.
3308 Affected files silcd/server.c, silcd/silcd.c.
3310 * Fixed MOTD to return the MOTD file server name. Affected
3311 file silcd/command.c.
3313 * Added INFO command reply handling to the Irssi SILC Client.
3314 Affected file irssi/src/silc/core/client_ops.c.
3316 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3318 * Fixed the silc_idcache_list_* routines to really support
3319 the dynamic list. Fixes a crash. Affected file is
3320 lib/silccore/silcidcache.c.
3322 * Fixed the LIST command reply to really call LIST command's
3323 pending callbacks. Affected file silcd/command_reply.c.
3325 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3327 * Update conn->local_entry->nickname after giving NICK
3328 command. Affected file lib/silcclient/command.c.
3330 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3332 * Added the [pid] option to the silcd configuration file
3334 Affected files: serverconfig.[ch] and silcd.c
3336 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3338 * Save fingerprint in WHOIS command reply in server.
3339 Affected file silcd/command_reply.c.
3341 * Fixed NICK commands pending callback registration.
3342 Affected file lib/silcclient/command.c.
3344 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3346 * Use ++server->cmd_ident when sending commands in server,
3347 instead of random number. Affected file silcd/command.c.
3349 * Fixed GETKEY command reply to call actually GETKEY pending
3350 command callbacks. Affected file silcd/command_reply.c.
3352 * A bit stricter check for nicknames. Check for same nickname
3353 in NICK command also. Affected file silcd/command.c.
3355 * Do not call INFO command everytime client ID changes, only
3356 during first connecting. Affected file lib/silcclient/client.c.
3358 * Set the new nickname only after successful command reply for
3359 NICK command is returned by server. Affected file
3360 lib/silcclient/command.c.
3362 * Remove nicknames from nicklist during server_signoff notify.
3363 Should fix /NAMES bit more. The affected file is
3364 irssi/src/silc/core/silc-channels.c.
3366 * Added `fingerprint' field to the SilcIDListData in the
3367 silcd/idlist.h to hold the fingerprint of the client's
3370 Send the fingerprint of the client's public key in WHOIS
3373 Affected files silcd/command.c, and silcd/idlist.[ch].
3375 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3376 create fingerprint from given data.
3378 * Show the fingerprint of the client's public key in WHOIS.
3379 Affected files irssi/src/module-formats.[ch] and
3380 irssi/src/silc/core/client_ops.c.
3382 * Format the multiple same nicknames also during JOIN and
3383 NICK_CHANGE notifys. Affected file is
3384 lib/silcclient/client_notify.c.
3386 * Do not print error on screen for invalid private message
3387 payload since it can come if someone is sending private
3388 messages with wrong key. Affected file
3389 lib/silccore/silcprivate.c.
3391 * Fixed multiple concurrent /PING crash. Affected file
3392 lib/silcclient/command.c.
3394 * Changed the wrong ID encoding. All IP addresses must be
3395 in MSB first order in encoded format. They were encoded
3396 wrong and was in LSB format. Affected files are
3397 silcd/serverid.c, lib/silcutil/silcutil.c.
3399 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3401 * Call the `connect' client operation through the scheduler
3402 in case of error. Affected file lib/silcclient/client.c.
3404 * Call the `failure' client operation even if the error
3405 occurred locally during a protocol. Affected file is
3406 lib/silcclient/protocol.c.
3408 * Added support of sending LIST command to router from normal
3409 server. This way normal server can get list of all channels
3410 in the network too. Fixed the channel list sending in the
3411 server too. Affected files are silcd/command.c, and
3412 silcd/command_reply.[ch].
3414 * Added silc_server_update_channels_by_server and
3415 silc_server_remove_channels_by_server. They are used during
3416 disconnection of primary router and in backup router protocol.
3417 Affected file silcd/server_util.[ch], silcd/server.c and
3418 silcd/server_backup.c.
3420 * Fixed channel adding to global list in IDENTIFY command
3421 reply in server. Affected file silcd/command_reply.c.
3423 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3425 * If the incoming packet type is REKEY or REKEY_DONE process
3426 that packet always synchronously. Fixes yet another MAC
3427 failed error on slow (dialup) connections. Affected file
3428 lib/silcclient/client.c and silcd/server.c.
3430 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3432 * Call check_version SKE callback for initiator too. Affected
3433 file lib/silcske/silcske.c.
3435 * Implemented fix for security hole found in the SKE that was
3436 fixed in the specification few days back; the initiator's
3437 public key is now added to the HASH value computation.
3438 Added backwards support for the old way of doing it too, for
3439 old clients and old servers. Affected file is
3440 lib/silcske/silcske.c.
3442 * Enabled mutual authentication by default in SKE. If initiator
3443 is not providing mutual authentication the responder will
3444 force it. This will provide the proof of posession of the
3445 private key for responder. The affected files are
3446 lib/silcclient/protocol.c and silcd/protocol.c.
3448 * Do not cache anymore the server's public key during SKE.
3449 We do mutual authentication so the proof of posession of
3450 private key is done, and if the server is authenticated in
3451 conn auth protocol with public key we must have the public
3452 key already. Affected file silcd/protocol.c.
3454 * Added new global debug variable: silc_debug_hexdump. If
3455 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3456 file lib/silcutil/silclog.[ch].
3458 * Fixed compilation warning due to char * -> const char *.
3459 Affected files lib/silcutil/silcnet.h, and
3460 lib/silccore/silcauth.[ch].
3462 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3464 * Fixed CMODE command when new channel key was created. If
3465 the creation failed the old key was removed. Next time giving
3466 same command would crash the server since the old key was
3467 freed already. Affected file silcd/command.c.
3469 * Fixed the silc_server_announce_get_channels to not crash
3470 on reconnect. Affected file silcd/server.c.
3472 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3474 * Added silc_log_set_debug_string function to set a regex
3475 string to match for debug output. Only the function names,
3476 or filenames matching the given debug string is actually
3477 printed. This way it is possible to filter out those debug
3478 strings that user is not interested in.
3480 Fixed a bug in silc_string_regexify.
3482 Affected files lib/silcutil/silclog.[ch], and
3483 lib/silcutil/unix/silcunixutil.c.
3485 * Changed the -d options in both server and Irssi SILC client
3486 to take the debug string as argument. Affected files
3487 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3489 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3491 * Added silc_hash_babbleprint to create a Bubble Babble
3492 Encoded fingerprint. The encoding is developed by Antti
3493 Huima (draft-huima-babble-01.txt), and it creates human
3494 readable strings out of binary data. Affected file
3495 lib/silccrypt/silchash.[ch].
3497 * Print the babble print now in addition of fingerprint as well
3498 in Irssi SILC client. Affected files are
3499 irssi/src/fe-common/silc/module-formats.[ch],
3500 irssi/src/fe-common/silc/core/client_ops.c.
3502 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3504 * Fixed a security problem found in SKE. The initiator's
3505 public key too is now added to the HASH hash value creation
3506 which is signed by the responder to create the SIGN value.
3507 This will prevent anyone in the middle to lie to the responder
3508 about the initiator's public key. If this is done now, the
3509 man in the middle will get caught. Updated the protocol
3512 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3514 * Better installation directory handling. Configure module
3515 paths and other paths automatically to example_silc* files
3516 in doc/. A patch by toma.
3518 * Fixed compiler warning from MPI library, and from SILC RNG.
3521 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3522 It can be configured with ./configure. A patch by toma.
3524 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3526 * Find correct make to use in prepare-clean. A patch by
3527 toma. Affected file prepare-clean.
3529 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3531 * Added irssi variables use_auto_addr, auto_bind_ip,
3532 auto_bind_port and auto_public_ip.
3534 * Changed the interface for silc_client_send_key_agreement
3535 in lib/silcclient/silcapi.h
3539 irssi/src/silc/core/silc-core.c
3541 lib/silcclient/silcapi.h
3542 irssi/src/silc/core/silc-channels.c
3543 lib/silcclient/client_keyagr.c
3546 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3548 * Added silc_pkcs_public_key_compare to compare two
3549 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3551 * Check that the client who set the founder mode on the
3552 channel is the same client that is giving the founder
3553 mode to itself. It is done by comparing the saved public
3554 key (it is saved even in the authentication is passphrase).
3555 Affected file silcd/command.c.
3557 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3559 * Do not process packet for disconnected socket connection.
3560 Affected file lib/silccore/silcpacket.c.
3562 * Process the DISCONNECT packet through scheduler in the
3563 client library. Affected file lib/silcclient/client.c.
3565 * Fixed the silc_client_packet_parse to not to increase
3566 the packet sequence number if the conn->sock and the
3567 current socket connection is not same. This can happen
3568 for example during key agreement when the conn includes
3569 multiple socket connections (listeners). Affected file
3570 lib/silcclient/client.c.
3572 * The sender of the file transfer request now provides also
3573 the pointer (listener) for the key exchange protocol. If
3574 the listener cannot be created then it sends empty key
3575 agreement and lets the receiver provide the listener.
3577 Added `local_ip' and `local_port' arguments to the
3578 silc_client_file_send. If they are provided they are used,
3579 if not then it will attempt to find local IP address, if
3580 not found or bind fails then the remote client will provide
3583 Affected files are lib/silcclient/client_ftp.c and
3584 lib/silcclient/silcapi.h.
3586 * Extended the FILE SEND command to support defining the
3587 local IP and port for key exchange listener. They are
3588 optional. Affected file irssi/src/silc/core/silc-servers.c.
3590 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3592 * Defined to WHOIS command reply the sending of fingerprint
3593 of the client's public key (if the proof of posession of the
3594 corresponding private key is verified by the server).
3595 Updated to the protocol specification.
3597 * Added support of receiving the client's public key's
3598 fingerprint in command reply in client library. Affected
3599 file is lib/silcclient/command_reply.c, and
3600 lib/silcclient/idlist.[ch].
3602 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3604 * Do not send over 128 chars long nickname to the server
3605 in NICK command. Affected file lib/silcclient/command.c.
3607 * Do not send over 256 chars long channel names to the server
3608 in JOIN command. Affected file lib/silcclient/command.c.
3610 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3612 * Assure that silc_server_close_connection cannot be called
3613 twice for same socket context. Affected file is
3616 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3618 * Send error message to application if opening file for
3619 writing during file transfer fails. Affected file is
3620 lib/silcclient/client_ftp.c.
3622 Remove all file transfer sessions for a client that we're
3623 removing from ID cache.
3625 Affected file is lib/silcclient/client_ftp.c.
3627 * Fixed silc_net_addr2bin to return correct address. Affected
3628 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3630 * Fixed file transfer session removing on signoff notify.
3631 Affected file irssi/src/silc/core/silc-servers.c.
3633 * Added the SilcClientFileError to be returned in the monitor
3634 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3635 Affected file lib/silcclient/silcapi.h.
3637 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3639 * Fixed a crash in silc_client_ftp_free_sessions and
3640 silc_client_ftp_session_free_client. Affected file
3641 lib/silcclient/client_ftp.c.
3643 * Added `disabled' field in the SilcChannelEntry in the server
3644 to indicate if the server entry is disabled. Affected file
3645 silcd/idlist.h, silcd/command[_reply].c.
3647 * SILC server adds now /var/run/silcd.pid everytime it is
3648 started. Affected file silcd/silcd.c.
3650 * Added silc_server_packet_send_clients to send a packet to
3651 the provided table of client entries. Affected file
3652 silcd/packet_send.[ch].
3654 * Fixed a crash in client resolving in client_prvmsg.c in
3655 client library. Affected file lib/silcclient/client_prvmsg.c.
3657 * Do not actually remove the client directly from ID cache
3658 during SERVER_SIGNOFF, but invalidate it. This way we
3659 preserve the WHOWAS info for the client. Affected file
3660 silcd/server_util.c.
3662 * Fixed SERVER_SIGNOFF notify handling in the server. The
3663 server is now able to process incoming SERVER_SIGNOFF notify
3664 for a server that it doesn't even know about. It will remove
3665 the clients provided in the notify. Affected file
3666 silcd/packet_receive.c.
3668 * Check for partial packet in data queue after every packet that
3669 was found from the queue. Return and wait for more data if
3670 there is partial data in queue. Affected file is
3671 lib/silccore/silcpacket.c.
3673 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

3682 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3684 * Added better monitor of file transfers. It now monitors
3685 key agreement protocol during the file transfer too. Added
3686 error reporting too. Affected files
3687 irssi/src/silc/core/silc-servers.c,
3688 irssi/src/fe-common/silc/module-formats.[ch].
3690 * Wrote a help file for FILE command.
3692 * Added silc_rng_global_get_byte_fast to get not-so-secure
3693 random data as fast as possible. Random data is read from
3694 /dev/urandom if available and from the SILC RNG if not
3695 available. It is used in padding generation. Affected file
3696 lib/silccrypt/silcrng.[ch].
3698 * All packets in client library are now processed synchronously.
3699 Optimized packet processing a lot. Affected file
3700 lib/silcclient/client.c.

3711 * Assure that silc_client_notify_by_server_resolve does not
3712 resolve the client information multiple times. If it cannot
3713 be found by the first it cannot be found at all. Affected
3714 file lib/silcclient/client_notify.c.
3716 * Fixed WHOWAS command reply calling. Affected file
3717 lib/silcclient/command_reply.c.
3719 * Removed all references to silc_idlist_get_client from the
3720 Irssi SILC client since that call is internal call used by
3721 the library. The Irssi SILC client will use now client
3722 retrieval functions found in silcapi.h.
3724 * Fixed a bug in resolving nickname info before sending
3725 private message. It used freed memory. Affected file
3726 irssi/src/silc/core/silc-servers.c.
3728 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3730 * Assure my_channels statistics cannot go negative in server.
3731 Affected files silcd/server.c, silcd/server_util.c.

3747 * Added silc_net_localip to return local host's IP address.
3748 Affected file lib/silcutil/silcnet.[ch].
3750 * If key exchange or rekey protocol is active for a connection
3751 parse all packets syncronously since there might be packets
3752 in packet queue that we are not able to process without first
3753 processing packets before them. Affected file silcd/server,
3754 lib/silcclient/client.c.
3756 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3757 whether library should continue processing the packet.
3758 Affected file lib/silccore/silcpacket.h.

3804 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3805 is incomplete and is being resolved, it won't be resolved
3808 Make sure also that USERS command reply does not resolve
3809 twice information. Affected file is
3810 lib/silcclient/command_reply.c.
3812 Make sure that silc_client_get_clients_by_list does not
3813 resolve twice same information.
3815 * Check for valid client->id in the silc_server_free_client_data.
3816 Affected file silcd/server.c.
3818 * Fixed /GETKEY nick@server not to crash if the server entry
3819 is not found. Affected file lib/silcclient/command.c.
3821 * Fixed the silc_server_check_cmode_rights to check the
3822 requested modes correctly. Affected file silcd/command.c.

3827 Affected file silcd/command.c.
3829 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3831 * Call the silc_server_udpate_servers_by_server in the
3832 primary router that comes back online in the backup resuming
3833 protocol. Otherwise it routes packets wrong. Affected file
3834 silcd/server_util.[ch], silcd/server_backup.c.
3836 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3838 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3839 lib/silcutil/silcbuffmt.[ch].
3841 * Redefined the SILC packet header to include the padding
3842 length. Affected file lib/silccore/silcpacket.[ch].
3844 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3845 length for maximum padding up to 128 bytes). Affected
3846 file lib/silccore/silcpacket.h.
3848 * Removed all backwards support for old 0.5.x MAC thingies.
3849 The SILC packet header change makes it impossible to be
3850 backwards compatible.
3852 * Send the ENDING packet with timeout in the backup resuming
3853 protocol. This is to assure that all routers has connected
3854 to the primary router. Affected file silcd/server_backup.c.
3856 * Changed the RNG to take the first IV from random data. It
3857 used to take it from zero actually. Changed the RNG also
3858 to use /dev/urandom during session. /dev/random is used
3859 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3861 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3863 * Changed the SILC packet header to have the first two bytes
3864 (the packet length) encrypted. Affected files aroung the
3865 code tree, lib/silccore/silcpacket.[ch]. Removed the
3866 SilcPacketCheckDecrypt callback. It is not needed anymore
3867 since the silc_packet_receive_process will determine now
3868 whether the packet is normal or special.
3870 * Implemented the unidirectional MAC keys. Affected files
3871 lib/silcske/silcske.c, silcd/protocol.c and
3872 lib/silcclient/protocol.c.
3874 * Implemented the packet sequence number to the MAC computation.
3875 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3876 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3877 lib/silcclient/protocol.c.
3879 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3881 * Allow backup router to announce servers. All servers
3882 announced by backup router are added to the global list
3883 automatically. Update hte server's socket to our primary
3884 router also when backup router announces a server.
3885 Affected file silcd/packet_receive.c.
3887 * Do not update the client->router in the function
3888 silc_server_udpate_clients_by_server if the client is on
3889 global list. We might fail to find any specific server
3890 for locally connected clients and local cell clients. They
3891 should still use the `from' and not `to' as client->router.
3892 This fixes backup router resuming protocol. Affected file
3893 silcd/server_util.c.
3895 * Decrease channel statistics count only if the channel
3896 deletion worked. Affected files are silcd/server.c and
3897 silcd/server_util.c.
3899 * Added silc_server_update_servers_by_server to update origin
3900 of all server entries. Used during backup router protocol.
3901 Affected files silcd/server_util.[ch], silcd/server.c. and
3902 silcd/backup_router.c.
3904 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3905 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3906 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3907 lib/silccrypt/silchmac.c.
3909 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3911 * Assure that router cannot reroute the same channel message
3912 to the sender. Affected file silcd/packet_receive.c.
3914 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3916 * Made better checks that the channel message is not sent
3917 to the router it came from. Affected file is
3918 silcd/packet_send.c. Fixed memory leak too.
3920 * Announce informations for incoming router connection, but
3921 only after checking if it is replaced by backup router.
3922 Affected file silcd/packet_receive.c.
3924 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3926 * Fixed the backup resuming protocol to work in multiple
3927 router environment. Affected file silcd/server_backup.c.
3929 * Route packet only to one router in the function
3930 silc_server_packet_send_to_channel. Affected file is
3931 silcd/packet_send.c.
3933 * Fixed silc_server_send_notify_dest to set the broadcast
3934 flag. Fixed the silc_server_send_notify_topic to actually
3935 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3936 Affected file silcd/packet_send.c.
3938 * Changed the SFTP Filesystem interface. Changed the
3939 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3940 the filesystem operation function. The SilcSFTPFilesystem
3941 is now a context that is allocated by all filesystem allocation
3942 functions and it already includes the operations structure
3943 and filesystem specific context. It is given as argument
3944 now to the silc_sftp_server_start. This made the interface
3945 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3946 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3948 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3950 * Changed the backup router adding and getting interfaces
3951 in the server. The router that will be replaced by the
3952 specified backup router is now sent as argument. Affected
3953 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3956 * Added silc_net_addr2bin_ne to return the binary form of
3957 the IP address in network byte order. Affected files
3958 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3960 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3962 * Check for existing server ID in silc_server_new_server
3963 and in silc_server_connect_to_router_final and remove the
3964 old entry if it exists. Affected file silcd/packet_receive.c,
3967 * Send the channel message always to only one router, either
3968 in upstream or downstream. Affected file is
3969 silcd/packet_send.c.
3971 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3973 * Wrote the definition of the backup resuming protocol to the
3974 protocol specification.
3976 * Removed one redundant channel key generation from normal
3977 server during joining procedure. Removed one redundant
3978 channel key sending from server to router during joining
3979 procedure. Affected file silcd/command.c.
3981 * Made minor bugfixes to the backup router resuming protocol.
3982 Affected file silcd/server_backup.c, server.c.
3984 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3986 * Added --disable-asm configuration option. Affected files
3987 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3990 * Implemented the backup resuming protocol that is used to
3991 resume the primary router position in the cell after the
3992 primary router comes back online. Affected files
3993 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3994 and silcd/server_util.[ch].
3996 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3998 * Sleep two (2) seconds after sending QUIT command to server.
3999 Affected file lib/silcclient/command.c.
4001 * Assure that if outgoing data buffer is pending do not force
4002 send any data. Affected file silcd/packet_send.c.
4004 * Assure that if outgoing data buffer is pending do not force
4005 send any data. Affected file lib/silcclient/client.c.
4007 * Implemented the backup router support when the primary router
4008 goes down. The servers and routers can now use the backup
4009 router as new primary router without loosing connectivity.
4011 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4013 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
4014 in the server to indicate disabled entry. All data read
4015 from the connection will be ignored and no data is sent
4016 for entry that is disabled. Affected files are
4017 silcd/idlist.h, silcd/server.c.
4019 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4021 * Created SFTP client and server test programs in the
4022 lib/silcsftp/tests directory.
4024 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4026 * Implemented memory filesystem (virtual filesystem) for
4027 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
4030 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4032 * Implemented the SFTP (SSH File Transfer Protocol) to the
4033 lib/silcsftp. It includes SFTP client and SFTP server
4036 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4038 * Moved lib/silccore/silcprotocol.[ch] to the
4039 lib/silcutil library.
4041 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
4042 take variable argument list pointer as argument. Affected
4043 file lib/silcutil/silcbuffmt.[ch].
4045 * Added silc_buffer_set function that is used to set data
4046 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
4047 Affected file lib/silcutil/silcbuffer.h.
4049 * Changed various routines in the core library to use the new
4050 silc_buffer_set instead of allocating new buffer only for
4053 * Added 64-bit value formatting and unformatting support to the
4054 silc_buffer_[un]format routines. Affected file is
4055 lib/silcutil/silcbuffmt.[ch].
4057 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
4058 to includes/bitmove.h.
4060 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4062 * Fixed channel user mode saving in client library. Affected
4063 file lib/silcclient/command[_reply].c.
4065 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4067 * Defined the file transfer to the SILC Protocol. Added
4068 new packet type SILC_PACKET_FTP and defined File Transfer
4069 Payload. The mandatory file transfer protocol is SFTP
4070 (SSH File Transfer Protocol). Affected file in addition
4071 of the internet draft is lib/silccore/silcpacket.h.
4073 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
4074 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
4075 is used as part of backup router protocol when the primary
4076 router of the cell is back online and wishes to resume
4077 the position as primary router.
4079 * Redefined the MAC generation keys in the protocol. The
4080 same key is not used anymore in both direction. Both
4081 direction will now use different keys for sending and
4082 receiving. This fixes a potential security flaw. This
4083 change causes incompatibilities in the protocol.
4085 * Redefined also the MAC computation from the packet.
4086 An packet sequence number is now added to the MAC
4087 computation. This prevents possible replay attacks against
4088 the protocol. This change too causes incompatibilities
4091 Added `sequence' field to the SilcPacketContext to hold
4092 the current sequence number for the packet.
4094 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4096 * Added `created' field to the SilcIDListData in the file
4097 silcd/idlist.h to indicate the time when the entry was
4100 * Added `created' field to the SilcChannelEntry too. Affected
4101 file silcd/idlist.h.
4103 * Added `creation_time' aguments to all the announcement functions
4104 in the server. If it is provided then only the entries that
4105 was created after the provided time frame are actually
4106 announced. Affected file silcd/server.[ch].
4108 * The protocol says that the Channel ID's IP address must be
4109 based on the router's IP address. Added check for this in
4110 the silc_server_new_channel when processing incoming New Channel
4111 Payload. Affected file silcd/packet_receive.c.
4113 * Print out the correct version with --version in SILC client.
4114 Affected file irssi/src/silc/core/silc-core.c.
4116 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4118 * Fixed WHOWAS command to check for completnes of the client
4119 entry always, not just when the command is coming from client.
4120 Affected file silcd/command.c.
4122 * Added new function silc_server_packet_queue_purge to purge the
4123 outgoing data queue to the network. After the function returns
4124 it is guaranteed that the outgoing packet queue is empty.
4125 Affected file silcd/packet_send.[ch].
4127 * Purge the outgoing packet queue in the rekey protocol's final
4128 callback to assure that all rekey packets go to the network
4129 before quitting the protocol. Affected file silcd/server.c.
4131 * Added silc_client_packet_queue_parse as similar function as
4132 in server to the client library. The affected file is
4133 lib/silcclient/client.c.
4135 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4137 * Splitted silcd/server.c and created silcd/server_util.[ch]
4138 for utility functions.
4140 * Added new socket flag SILC_SF_DISABLED to indicate that the
4141 connection is open but nothing can be sent to or received from
4142 the connection. Affected file lib/silcutil/silsockconn.[ch].
4143 The checking for disabled socket is checked in the low level
4144 silc_socket_write and silc_socket_read functions.
4146 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4148 * Allow only nicknames and channel names that fits into the
4149 7-bit unsigned char ASCII set. Affected file silcd/command.c.
4151 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4153 * When processing JOIN command reply in server check that if
4154 the channel exists in our global list we'll move it the local
4155 list. Affected file silcd/command_reply.c.
4157 * Fixed the check whether client is joined on the channel already
4158 in JOIN command. Affected file lib/silcclient/command.c.
4160 * Fixed the JOIN command reply to check whether the channel
4161 already exists. Affected file lib/silcclient/command_reply.c.
4163 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4165 * Added silc_ske_status_string to map the SKE error numbers
4166 to readable strings. The affected files are
4167 lib/silcske/silcske[_status].[ch].
4169 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4171 * Do not show the private channels on the WHOIS channel list
4172 as it is not allowed by the protocol. The affected file is
4175 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4177 * Assure that the packet length digged from the actual packet
4178 is something sensible in the silc_packet_decrypt_rest_special
4179 in lib/silccrypt/silcpacket.c.
4181 * Free and NULL the allocated pointer in silc_hmac_alloc if
4182 the HMAC allocation fails. The affected file is
4183 lib/silccrypt/silchmac.c.
4185 * Print the selected security properties to the log files in
4186 the server. Affected file silcd/protocol.c.
4188 * Add SKE's reference counter even if calling the completion
4189 callback manually. Otherwise it goes negative, although it
4190 does not cause any problems. The affected file is
4191 lib/silcske/silcske.c.
4193 * Remove the client entry with short timeout after giving the
4194 KILL command. Affected file lib/silcclient/command.c.
4196 * Fixed to send error reply in WHOIS and IDENTIFY commands in
4197 case all found clients are already disconnected (WHOWAS would
4198 found them) in the server. Affected file silcd/command.c.
4200 * Update the last_receive (time of last data received) to be
4201 updated only when received private or channel message so that
4202 the idle time showed in WHOIS makes more sense.
4204 * Added boolean field `valid' in to the SilcClientEntry in the
4205 client library to indicate whether the entry is valid or not.
4206 This fixes the nickname change bug on channel when changing
4207 the nickname to be same than the old (like nick to Nick) the
4208 nickname formatter doesn't set the new nick anymore to Nick@host.
4209 Affected file lib/silcclient/idlist.[ch].
4211 * Now actually fixed the nickname changing on disconnection.
4212 Added new function silc_change_nick to the Irssi SILC Client.
4213 Affected file irssi/src/silc/core/client_ops.c,
4214 irssi/src/silc/core/silc-nicklist.[ch].
4216 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4218 * Check that the public key exists in the GETKEY command before
4219 trying to encode it. Affected file silcd/command.c.
4221 * Print some notifications on received public keys with GETKEY
4222 command in the Irssi SILC Client. Affected files are
4223 irssi/src/fe-common/silc/module-formats.[ch],
4224 irssi/src/silc/core/client_ops.c.
4226 * Use IDENTIFY command to resolve the server information in the
4227 GETKEY command instead of INFO command. Affected file
4228 lib/silcclient/command.c.
4230 * All command reply functions in the client library now calls
4231 the pending command reply callbacks even if an error has
4232 occurred. The server has done this a long time and now it was
4233 time to move the client library to this as well. Now all
4234 errors can be delivered back to the pending command reply
4235 callbacks if necessary. Affected files are
4236 lib/silcclient/command[_reply].[ch].
4238 * Change the nickname on disconnection back to the username
4239 because in reconnect the server will enforce it to it anyway.
4240 Affected file irssi/src/silc/core/silc-servers.c.
4242 * Fixed a config file parsing bug in the Irssi SILC client.
4243 Affected file irssi/src/silc/core/clientconfig.c.
4245 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4247 * When printing the channel mode on JOIN, verify that the
4248 channel key and channel's HMAC are valid. Affected file
4249 irssi/src/silc/core/client_ops.c.
4251 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4253 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
4254 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
4255 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
4257 * Removed channel key rekey task deleting from the function
4258 silc_server_save_channel_key. Affected file silcd/server.c.
4259 Added explicit timeout task context instead that is used to
4260 delete the task if we are registering a new task before the
4261 new task has elapsed.
4263 * When channel key rekey occurs the client library now saves
4264 the old channel key for a short period of time (10 seconds) and
4265 is able to use it in case some is still sending channel
4266 messages encrypted with the old key after the rekey. Affected
4267 file lib/silcclient/[idlist.h|client_channel.c].
4269 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4271 * Added check to the silc_server_new_id_real to not accept
4272 new ID if it is the sender's own ID. Affected file is
4273 silcd/packet_receive.c.
4275 * Assure that we do not announce ourself or the one we've
4276 sending our announcements when we're router and are announcing
4277 servers to our primary router. Affected file silcd/server.c.
4279 * Fixed silc_server_command_identify_check_client to assemble
4280 correct WHOIS packet. It send corrupted WHOIS packet and
4281 caused problem with router to router connections. Affected
4282 file silcd/command.c.
4284 Fixed also silc_server_command_whois_check the same way
4285 as for the IDENTIFY command.
4287 * Added new SilcIDListStatus to the server in the SilcIDListData
4288 structure. The status now includes the current status of
4289 the entry (like registered, resolved etc.). Affected file
4290 silcd/idlist.[ch]. Defined a bunch of different status types
4291 as well. This replaced the old boolean registered field as well.
4293 Added resolve_cmd_ident field to the SilcClientEntry structure
4294 too so that if the entry is for example being resolved so
4295 another command may attach to the same pending command reply
4296 without requiring to resolve the same entry again. This concept
4297 should optimize the WHOIS and the IDENTIFY resolving under
4298 heavy load by taking away unnecessary resolving for entries
4299 that are being resolved already.
4301 Added support for adding multiple pending commands for one
4302 command idenfier. Affected file silcd/command[_reply].[ch].
4304 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4305 before deleting the data. Otherwise the hash table will have
4306 freed data in comparison functions. Affected file is
4307 silcd/command_reply.c.
4309 * Fixed silc_idlist_replace_client_id to add the new entry to
4310 the cache with NULL nickname. Otherwise there will be invalid
4311 memory as the nickname after the nickname is freed. Affected
4312 file silcd/packet_receive.c.
4314 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4315 saved into wrong slots because the previous number of entries
4316 was not taken into account. Affected file silcd/idlist.c.
4317 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4319 * If we are router and we receive JOIN notify to a channel that
4320 does not have any users then notified client is marked as the
4321 channel founder, as it is it. The affected file is
4322 silcd/packet_receive.c
4324 * Added to the extended hash table API's table_del_*ext functions
4325 the destructor as argument too, so that the caller can decide
4326 which destructor to use or whether to use destructor at all.
4327 Affected file lib/silcutil/silchashtable.[ch].
4329 * Fixed ID Cache purging. It actually deleted the entries from
4330 the hash table after the data was freed. The hash table ended
4331 up comparing freed memory. The affected file is
4332 lib/silccore/silcidcache.c.
4334 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4336 * Fixed Irssi SILC client's KILL command's HELP syntax.
4338 * The USERS command now resolves the detailed user information
4339 if the userinfo field is missing. Affected file is
4340 lib/silcclient/command_reply.c.
4342 * Do not print error in silc_file_read if the read file does
4343 not exist. Just silently return NULL. Affected file is
4344 lib/silcutil/silcutil.c.
4346 * Fixed the silc_log_output to not wine about NULL filename
4347 and to not create some bogus " " filename. Affected file is
4348 lib/silcutil/silclog.c.
4350 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4352 * Fixed various printing bugs on the user interface in the
4353 Irssi SILC Client. Minor changes that were forgotten from
4356 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4358 * Fixed the configure.in.pre and the compilation and distribution
4359 environment to support the new autoconf 2.52. That version is
4360 now required to compile the CVS trunk.
4362 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4364 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4365 to generally parse user@fqdn format strings. Affected file
4366 lib/silcutil/silcutil.c.
4368 * Added nickname_format and nickname_force_format fields to the
4369 SilcClientParams structure. The first one defines the format
4370 for the nicknames that the library will enforce if the receives
4371 multiple same nicknames. The second one is boolean value and
4372 can be used to force the library to always enforce the format
4373 to the nicknames regardles whether there are multiple nicknames
4374 or not. This configurable formatting was employed to flexibly
4375 support accessing multiple nicknames from the user interface.
4376 The userinterface can now set the nicknames to what ever format
4377 they prefer. Affected file lib/silcclient/silcapi.h.
4379 Added function silc_client_nickname_format to the file
4380 lib/silcclient/idlist.c. It performs the nickname formatting.
4382 Added new field `hostname´ to the SilcClientEntry context.
4383 It holds the hostname of the client. Affected file is
4384 lib/silcclient/idlist.h.
4386 * Irssi SILC Client sets the nicknames in nick@hostn format.
4387 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4388 irssi/src/silc/core/silc-core.c.
4390 The WHOIS printing now also shows both the real nickname and
4391 the formatted nickname so that user knows how to access the
4392 user if there are multiple same nicknames cached. Affected
4393 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4394 printing formatting too to take the hostname now as a separate
4395 argument. The Affected file is
4396 irssi/src/fe-common/silc/modules-formats.[ch].
4398 * Changed the silc_client_get_clients_local to accept the formatted
4399 nickname as argument. It accepts the real nickname too but the
4400 formatted nickname can be used to find the true entry from
4401 multiple entries. Affected file lib/silcclient/silcapi.h and
4402 lib/silcclient/idlist.c.
4404 * Added nickname_format_parse field to the SilcClientParams.
4405 It is a callback function provided by the application to parse
4406 the nickname out of the formatted nickname string. The library
4407 calls it to get the nickname from the formatted string. Since
4408 the application generally knows better the format of the nickname
4409 string it parses it instead of the library, even though library
4410 encodes the formatted string. If the callback function is not
4411 provided then the library will use the string as is. The
4412 affected file is lib/silcclient/silcapi.h.
4414 * All the nickname strings passed to the client library in
4415 commands are now expected to be formatted nickname strings.
4416 If the command does not support the formatted nickname string
4417 it will assume that the sent string is the actual nickname.
4418 Affected file lib/silcclient/command.c.
4420 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4422 * Added public key authentication support to OPER and SILCOPER
4423 commands in the client library. Affected file is
4424 lib/silcclient/command.c.
4426 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4428 * Changed the get_auth_methdod client operation to be asynchronous.
4429 It can be async if the application resolves the authentication
4430 method from the server during the negotiation. Added new
4431 SilcGetAuthMeth completion callback that the application will
4432 call after resolving the authentication method.
4434 Added function silc_client_request_authentication_method that
4435 the application can use to resolve the authentication method
4436 from the server. Added also SilcConnectionAuthRequest callback
4437 that the library will call after the server has replied. The
4438 application can call this function if it does not know the
4439 current authentication method.
4441 Affected files are lib/silcclient/client.c and
4442 lib/silcclient/silcapi.h.
4444 * The Irssi SILC client now automatically resolves the authentication
4445 method incase any configuration information is not present (and
4446 currently there never is). The affected file is
4447 irssi/src/silc/core/client_ops.c.
4449 * Fixed public key authentication from the client library.
4450 Affected file lib/silcclient/protocol.c. Changed also the
4451 protocol specification about the public key authentication in
4452 the connection authentication protocol. The actual data to be
4453 signed is now computed with a hash function before signing.
4455 * Fixed the public key authentication from the server as well.
4456 Affected file silcd/protocol.c.
4458 * Removed the mlock()'s from the memory allocation routines.
4459 Affected file lib/silcutil/silcmemory.c. The ./configure does
4460 not check anymore for the mlock(). Affected file is
4463 * Fixed USERS command in server to allow the execution of the
4464 command for private and secret channels if the client sending
4465 the command is on the channel. Affected file silcd/command.c.
4467 * Fixed silc_client_get_clients_local to return the clients
4468 count correctly. It could return wrong value. Affected file
4469 lib/silcclient/idlist.c.
4471 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4473 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4474 types. The assembler optimizations seemed not to like 64-bit
4475 data types. The assmebler optimizations thus are now enabled
4476 also for BSD systems as opposed to only enable them for Linux.
4478 * Do not check for threads at all on BSD systems. Affected
4479 file configure.in.pre.
4481 * Removed -n and -h options from the Irssi SILC Client since
4482 they are not used in silc.
4484 * Fixed the prime generation to assure that the first digit
4485 of the generated random number is not zero since our conversion
4486 routines does not like number strings that starts with zero
4487 digit. If zero digit is seen the random number is regenerated.
4488 This caused some corrupted RSA keys when the zero first digit
4489 was met. Affected file lib/silcmath/silcprimegen.c.
4491 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4493 * Fixed WIN32 configuration in the ./configure script.
4494 Fixed to include xti.h on environments that has it.
4495 Patches by Carsten Ilchmann and andrew.
4497 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4499 * Changed the silc_id_create_client_id to be collision
4500 resistant. It is now assured that there cannot be created
4501 two same client ID's. I suspect that some weird bugs in
4502 the server were actually caused by duplicate Client IDs.
4503 Affected file silcd/serverid.[ch]. A router receiving
4504 new ID now also assures and informs the sending server
4505 if the ID caused collision.
4507 * Changed the silc_id_create_channel_id to also assure that
4508 there are no collisions.
4510 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4512 * Statement about ignoring the Mutual Authentication flag when
4513 performing rekey with PFS was a bit misleading. It is ignored
4514 if it was set in the initial negotiation, it cannot be even
4515 set in the rekey. Fixed in the ke-auth draft. Started the
4516 new versions of the protocol drafts in the doc/.
4518 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4520 * Fixed a bug in silc_client_command_identify_save when saving
4521 new channel information. The channel name was no duplicated
4522 and caused crash on exit. Affected file is
4523 lib/silcclient/command_reply.c.
4525 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4527 * Fixed the getkey command handling in the server. Send just
4528 empty OK reply to the sender if the key could not be fetched
4529 (but everything else was ok, like the key just was not available).
4530 Changed the public key parameter to optional in the protocol
4531 specs so that empty OK reply can be sent. Affected file
4534 Added a message to Irssi SILC client to tell to user if the
4535 server did not return a public key.
4537 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4539 * Fixed a channel key regeneration bug. It registered new
4540 timeout tasks exponentially until all system resources were
4541 used. Affected file silcd/server.c.
4543 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4545 * Added the SILC Document generator to the scripts/silcdoc.
4546 It can be used to generate the Toolkit Reference Manual out
4547 of the source tree. Internally it will also use the RoboDoc
4548 generator now imported in util/robodoc.
4550 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4552 * Added couple of return's in rekey protocol if error orccurred
4553 during the protocol. The execution must be terminated.
4554 Affected file silcd/protocol.c. Also, terminate the protocol
4555 always with timeout.
4557 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4559 * The client's Client ID was created initally from the wrong
4560 nickname (it could have been in format nick@host) in the
4561 silc_server_new_client. Affected file silcd/packet_receive.c
4563 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4565 * Added some SILC_LOG_ERROR's to various error conditions
4566 if client could not be added to ID cache. Affected files
4567 silcd/packet_receive.c and silcd/server.c.
4569 * When client's sock->user_data is freed, NULL also the
4570 client->router and client->connection pointers. Added check
4571 for these pointers being NULL to various places around the
4572 code. Affected file silcd/server.c.
4574 * Added client->data.registered == TRUE checks to various
4575 places around the code to assure that unregistered client's
4576 are not handled when it is not allowed. Affected file
4579 * Added `bool registered' fields to all
4580 silc_idlist_[server|client]_get_* routines to indicate whether
4581 the fetched client needs to be registered or not. Affected
4582 file silcd/idlist.[ch].
4584 * Add your own entry as registered to the ID cache in the
4585 server. Affected file server.c.
4587 * Fixed a bug in silc_server_new_server. The SilcServer was
4588 set as the new server's context instead of SilcServerEntry.
4589 This naturally caused some weird bugs.
4591 * Added "updated" field the SilcChannelEntry which indicates
4592 the time since the channel entry was last accessed. This
4593 can be used to determine whether it is necessary to
4594 announce the channel after backup resuming protocol.
4595 Affected files silcd/idlist.[ch].
4597 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4599 * Do not delete the channel rekey task when adding it
4600 for in silc_server_create_channel_key.
4602 * Changed the silc_server_create_channel_key to return
4603 TRUE or FALSE to indicate the success of the channel key
4606 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4608 * Fixed MSVC++ project files and added missing files to
4609 Makefiles under win32/.
4611 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4613 * Do not add TCP_NODELAY flag if the operating system
4614 does not have it defined. Affected files are
4615 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4617 * Fixed buffer overflow from Irssi SILC Client. Affected
4618 file irssi/src/fe-common/core/themes.c.
4620 * Fixed double free in client library in the file
4621 lib/silcclient/client.c when disconnecting from server.
4623 * Applied double free patch from cras to Irssi SILC client.
4624 Affected files irssi/src/core/[modules/expandos].c
4626 * Fixed the disconnection handling to Irssi SILC Client.
4627 The application must call silc_client_close_connection
4628 in ops->connect client operation in case of failure of
4629 the connection. Affected file is
4630 irssi/src/silc/core/client_ops.c.
4632 * Do not set sock->protocol to NULL in the function
4633 silc_client_close_connection after executing the protocol's
4634 final callback since the sock might not be valid anymore.
4635 Affected file lib/silcclient/client.c.
4637 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4639 * Do not enable SILC_THREADS if the linking with libpthread
4640 did not happen. Affected file configure.in.pre.
4642 * Added notion to protocol specification that server must
4643 verify the sent authentication payload with CMODE when
4644 setting the channel founder key. Implemented it to the
4645 server. Affected file silcd/command.c.
4647 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4649 * Added _EXTRA_DIST SILC distribution variable to the
4650 distributions file. It is used to conditionally add extra
4651 files or directories to the specific distribution. Affected
4652 files ./prepare, Makefile.am.pre and distributions.
4654 Removed the `_' from the start of the distribution names.
4657 * Added README.WIN32 for instructions to compile the Toolkit
4660 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4662 * Fixed a double free in disconnection in the server. Affected
4663 file is silcd/server.c.
4665 * Fixed the lib/silcske/groups.c to work now also with GMP
4666 MP library. The string conversion did not work when using
4667 specific base and the base is indicated in the string as well.
4669 * Created win32/ directory which now includes MSVC++ specific
4670 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4671 It will appear only in the toolkit distribution
4673 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4675 * Changed the key material distribution function in case when
4676 the hash output is too short. The data is now concatenated
4677 a bit differently than it used to. Made the change to the
4678 SKE protocol specification.
4680 * Added better GMP detection to configure.in.pre. A patch
4683 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4685 * Fixed a minor bug in SKE that might cause some problem on
4686 some platforms. Affected file lib/silcske/silcske.c.
4688 * Added the cookie checking for initiator in the SKE. It checks
4689 that the responder returns the sent cookie unmodified. The
4690 affected file is lib/silcske/silcske.c. Added new SKE
4691 error type INVALID_COOKIE that can be sent during the
4692 negotiation. Fixed some memory leaks as well.
4694 * Added the "invalid cookie" error message to Irssi SILC client's
4697 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4699 * Added `task_max' field to the SilcClientParams to indicate
4700 the maximum tasks the scheduler can handle. If set to zero,
4701 default values are used. Affected file lib/silcclient/silcapi.h.
4703 * Fixed memory leaks in silc_client_close_connection. Affected
4704 file lib/silcclient/client.c.
4706 * Added silc_client_del_client_entry to client library to free
4707 all memory of given client entry. Affected file is
4708 lib/silcclient/idlist.[ch].
4710 * Added new functions silc_client_del_channel and
4711 silc_client_del_server to delete channel and server entries.
4712 Affected file lib/silcclient/[silcapi.h/idlist.c].
4714 * Removed silc_client_del_client_by_id from silcapi.h.
4716 * Fixed the INFO command to return the server's own info
4717 correctly when querying by Server ID. Affected file is
4720 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4722 * Removed the non-blocking settings in WIN32 code in the
4723 silc_sock_[read/write] and added SleepEx instead. Affected
4724 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4725 of input data is now checked with FIONREAD and ioctlsocket.
4727 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4729 * Call silc_schedule_task_del_by_context in the
4730 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4731 Affected file lib/silccore/silcprotocol.c.
4733 * Call silc_protocol_cancel for active protocols in the
4734 silc_server_close_connection if the funtion
4735 silc_server_free_sock_user_data has not been called.
4736 Affected file silcd/server.c.
4738 * Generic tasks cannot be deleted using the del_by_fd
4739 task deleting function since generic tasks does not match
4740 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4742 * Added a notion to SILCOPER help file that the SILCOPER works
4743 only on router server, not on normal server.
4745 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4747 * Added for WIN32 support for the new scheduler as well.
4748 Affected file lib/silcutil/win32/silcwin32schedule.c.
4750 * Fixed the SHA1 implementation to work on various platforms.
4752 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4754 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4755 API. It is part of the scheduler now. Everything else is
4756 as previously but some functions has changed their names.
4757 Checkout the lib/silcutil/silcschedule.h for the interface.
4758 Updated all applications to use the new interface. Affected
4759 files are lib/silcutil/silcschedule.[ch].
4761 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4763 * Found a bug in the SKE implementation. The HASH value,
4764 specified by the protocol, was not computed correctly. The
4765 public key of the responder was not added to the computation
4766 even though it is mandatory. Affected file lib/silcske/silcske.c.
4767 This unfortunately causes incompatibilities with older
4768 clients and servers.
4770 * Added WIN32 specific network init and uninit functions:
4771 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4772 the Winsock2. Affected file lib/silcutil/silcnet.h and
4773 lib/silcutil/win32/silcwin32net.c.
4775 * Set the socket always to nonblocking mode on WIN32 after
4776 reading data or writing data. Affected file is
4777 lib/silcutil/win32/silcwin32sockconn.c.
4779 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4781 * Fixed various compilation problems under WIN32. Affected
4782 files lib/silcutil/win32/silcwin32thread.c and
4783 lib/silcutil/win32/silcwin32schedule.c.
4785 * Removed all _internal.h #includes from public header
4786 files. Internal headers must never be included from
4789 Removed also the lib/silcske/payload_internal.h file.
4791 * All include files that may be needed (public and some others
4792 included by the public headers) by application developers are
4793 now copied to the ./includes directory. It does not copy any
4794 internal headers. Affected file Makefile.defines.pre and all
4795 Makefile.am's under lib/ and subdirs.
4797 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4799 * Do not change the ~/.silc directory's permissions automatically.
4800 Affected file irssi/src/silc/core/clientutil.c.
4802 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4804 * Do not cancel the protocol in silc_server_close_connection
4805 it might cause recursion. Now cancelled in the function
4806 silc_server_free_sock_user_data. Affected file silcd/server.c.
4808 * Fixed the silc_server_remove_clients_by_server to regenerate
4809 the channel keys correctly finally. Added also new function
4810 silc_server_remove_clients_channels to actually do it.
4811 Affected file silcd/server.c.
4813 * Fixed the silc_server_new_channel to not crash by giving
4814 wrong router to the new channel. Affected file is
4815 silcd/packet_receive.c.
4817 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4819 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4820 which is given as argument to the silc_client_alloc now.
4821 It can be used to configure the client and set various parameters
4822 that affect the function of the client.
4824 * The USERS command in server did not check whether the channel
4825 is private or secret. Affected file silcd/command.c.
4827 * Added new argument to the USERS command in protocol specification.
4828 The USERS command now can take the channel name as argument
4829 as well. Added support for this in client and server and
4830 updated the protocol specs.
4832 * Completed the GETKEY command in client. It can be now used
4833 to fetch also servers public key not only some clients.
4834 Affected files lib/silcclient/command[_reply].c.
4836 * Added silc_client_get_server to return server entry by the
4837 server name. Affected files lib/silcclient/silcapi.h and
4840 * Redefined the IDENTIFY command in protocol specification to be
4841 more generic. It now can be used to query information about
4842 any entity in the SILC Network, including clients, servers and
4843 channels. The query may be based either the entity's name
4844 or the ID. Added support for this in both client and server.
4846 Affected files silcd/command.c and lib/silcclient/command.c
4847 and command_reply.c.
4849 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4850 the _from_client and _from_server functions. Affected file
4853 * Added silc_client_get_channel_by_id_resolve to the file
4854 lib/silcclient/silcapi.h to resolve channel information by
4855 its ID. Added also silc_client_get_channel_by_id that
4856 does not resolve it from the server.
4858 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4860 * Added SilcServerEntry context into the client library
4861 to represent one server. The INFO command now allocates
4862 these to save the resolved server info. For now on the
4863 client library will also keep information about servers,
4864 connected and resolved with INFO.
4866 The INFO command now allocates the SilcServerEntry context
4867 and saves the server info there. The COMMAND_REPLY in
4868 the INFO now returns the parameters to application in
4869 same order as defined in the protocol specification.
4871 The entries are cached in the client->server_cache.
4873 * The INFO command is now issued after received the Client ID
4874 from the server. Affected file lib/silcclient/client.c.
4876 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4877 to the application as the mode changer might be server.
4878 It is guaranteed that NULL is not returned anymore to the
4879 application. Affected file lib/silcclient/client_notify.c.
4881 The ID Type is now also passed to the application so that
4882 it can check whether the returned entry is SilcClientEntry
4885 Added new function silc_client_get_server_by_id to return
4886 the server entry by ID. Affected files are the
4887 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4889 * Do not create the channel in the Irssi SILC Client when issuing
4890 the JOIN command but when received the sucessful JOIN command
4891 reply. Otherwise the channel might get created even though we
4892 could not join it. The Affected file is
4893 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4895 * Fixed a channel joining bug in router. The router must also
4896 check the channel modes, invite and ban lists etc. when serving
4897 the JOIN command sent by normal server. Affected file is
4898 silcd/command.c. The router now resolves the client's
4899 information from the server who sent the JOIN command if it
4900 does not know it, and processes the JOIN command only after
4903 * Changed the SilcCommandCb to take new argument; void *context2.
4904 Affected file lib/silccore/silccommand.h
4906 The second argument in the command callbacks in the server now
4907 includes the SilcServerCommandReplyContext if the command was
4908 called as pending command callback from the command reply.
4909 Otherwise it is NULL. When called as pending the status of the
4910 command reply will be checked and if it was erronous the
4911 error will be sent to the original sender of the command.
4912 This way the client always receives the error messages even
4913 though the server was actually the one who received the error
4914 when it resent the command to router, for example. Affected
4915 files silcd/command[_reply].[ch].
4917 * Fixed sending WHOWAS command's error message to client if
4918 the requested client could not be found. It was missing.
4921 * Changed the CMODE and CUMODE commands reply arguments in the
4922 protocol specification. The Channel ID is now sent in both
4923 of the commands to identify the channel. Implemented this
4924 new feature to the client and server. Affected files
4925 lib/silcclient/command_reply.c and silcd/command.c.
4927 * Made better checks for invite and ban lists in the JOIN
4928 command in server. Affected file silcd/command.c.
4930 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4932 * The server now performs the incoming host IP/DNS lookup
4933 using the silc_socket_host_lookup and thus does not block
4934 the server anymore. Affected file silcd/server.c.
4936 * Completed the multi-thread support for SILC Scheduler in
4937 the lib/silcutil/silcschedule.c.
4939 * Fixed the configure.in.pre to detect the pthread correctly
4942 * Fixed a deadlock in silc_task_queue_wakeup in the file
4943 lib/silcutil/silctask.c.
4945 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4947 * Added new function silc_schedule_wakeup that is used in
4948 multi-threaded environment to wakeup the main thread's
4949 schduler. It needs to be used when a thread adds a new task
4950 or removes a task from task queues. After waking up, the
4951 scheduler will detect the task queue changes. If threads
4952 support is not compiled in this function has no effect.
4953 Implemented the wakeup mechanism to both Unix and WIN32
4954 systems. Affected files are lib/silcutil/silcschedule.[ch],
4955 lib/silcutil/unix/silcunixschedule.c and the
4956 lib/silcutil/win32/silcwin32schedule.c.
4958 * Added new function silc_task_queue_wakeup to wakeup the
4959 scheduler by the specified task queue. Affected file
4960 lib/silcutil/silctask.[ch].
4962 * The silc_socket_host_lookup_start now wakes up the scheduler
4963 after adding the timeout task. Affected file is
4964 lib/silcutil/silcsockconn.c.
4966 * The silc_socket_host_lookup is synchronous now if the threads
4967 support is not compiled in. However, the callback is still
4968 called asyncronously through the scheduler, anyway. Affected
4969 file lib/silcutil/silcsockconn.c.
4971 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4973 * Added new function silc_socket_host_lookup to perform
4974 asynchronous IP and FQDN lookups for the socket connection.
4975 Affected files lib/silcutil/silcsockconn.[ch].
4977 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4979 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4980 that may or may not compile the mutex support in.
4982 Changed the silc_mutex_alloc interface. It allocates the
4983 mutex now to the sent pointer and returns TRUE or FALSE.
4985 Affected file lib/silcutil/silcmutex.h.
4987 * Wrote the SILC Task Queue interface to support multi-threads.
4988 Affected file lib/silcutil/silctask.[ch].
4990 * Wrote the SILC Scheduler to support multi-threads. Affected
4991 file lib/silcutil/silcschedule.c.
4993 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4995 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4996 in lib/silcutil/win32/.
4998 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5000 * Defined SILC Mutex API and SILC Thread API and implemented
5001 them for Unix. Affected files are
5002 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
5003 lib/silcutil/unix/silcunixmutex.c and
5004 lib/silcutil/unix/silcunixthread.c.
5006 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5008 * Fixed the silc_server_remove_clients_by_server's channel
5009 key re-generation. The hash table handling was incorrect
5010 and would not work with many channels. Affected file is
5013 * Fixed some memory leaks around the server code.
5015 * Rewrote the silc_server_get_users_on_channel to support IPv6
5016 based Client ID's. Affected file silcd/server.c.
5018 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
5019 specification. However, a separate document must be written
5020 to define the detailed signing procedure and the payload
5021 associated with the flag. Defined the flag to the
5022 lib/silccore/silcchannel.h as well.
5024 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5026 * Changed the dynamic tables to static size tables in the
5027 lib/silccrypt/silchmac.c.
5029 * Removed GCC dependencies from the code. A patch by cras.
5031 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5033 * Do not show the error "Error receiving packet bla bla"
5034 in server if it really was not an error (-2 means that reading
5035 is pending). Affected file silcd/server.c.
5037 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5039 * Fixed a possible crash in silc_server_remove_clients_by_server
5040 in silcd/server.c. Fixed there also some memory leaks.
5042 * Fixed the silc_idlist_replace_client_id. It could replace
5043 wrong key in the hash table. Affected file silcd/idlist.c.
5045 * Do not check whether there are global users on the channel
5046 if the channel->global_users is FALSE. Affected functions
5047 silc_server_remove_from_one_channel and
5048 silc_server_remove_from_channels in silcd/server.c. Also,
5049 do not check if the removed client is local as we can be
5050 sure that global client was not removed from the channel
5051 and checking for global users is not needed.
5053 * The silc_server_remove_clients_by_server now re-generates
5054 the channel keys correctly for those channels that had
5055 clients removed from them. Affected file silcd/server.c.
5057 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5059 * Found the reason of random crashes in the server. We weren't
5060 ignoring the SIGPIPE signal (which can be sent in write())
5061 and it crashed the server. Affected file silcd/silcd.c.
5063 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5065 * Assure that sock->user_data is not NULL in the function
5066 silc_server_packet_send in silcd/packet_send.c.
5068 * Disconnect the remote connection if it could not be added
5069 to any ID lists in the server. The affected file is
5072 * Check in silc_server_packet_send[_real/dest] that the
5073 socket is not disconnecting and ignore the data if it is.
5074 Affected file silcd/packet_send.c.
5076 * Define inline to __inline on native WIN32 compilation.
5077 Affected file includes/silcwin32.h.
5079 * Added some explicit type casts for inline code since MSVC
5080 require them. Affected files lib/silcutil/silcbuffer.h,
5081 lib/trq/silcdlist.h and lib/trq/silclist.h.
5083 * Print warning in log files from now on if the packet
5084 decryption fails. Affected file silcd/server.c.
5086 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5088 * Changed the `say' client operation's interface to accept
5089 new `type' argument to indicate the type of the message sent
5090 by the library. The application may filter the library's
5091 messages according the type. The affected file is the
5092 lib/silcclient/silcapi.h.
5094 * Added two new functions to lib/silcclient/silcapi.h:
5095 silc_client_del_client and silc_client_del_client_by_id.
5096 Affected file lib/silcclient/idlist.c.
5098 * Moved the clientincludes.h from includes/ to silc/ and
5099 serverincludes.h from includes/ to silcd/.
5101 * The modes for the CMODE and CUMODE are now passed as
5102 uint32 for application with COMMAND_REPLY. The affected
5103 file is lib/silcclient/command_reply.c.
5105 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5107 * /WHOIS without arguments shows client's own information.
5108 Affected file lib/silcclient/command.c.
5110 * Changed PING to not accept any arguments. The specs
5111 says that client can ping only the connected server so
5112 requiring an argument is not needed. Affected file is
5113 lib/silcclient/command.c.
5115 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5117 * Fixed a fatal bug in private message sending and reception
5118 encryption and decryption when using private message keys.
5119 The implementation was incorrect and did not follow the
5120 specification. It causd that some of the message were
5121 lost since it did not use the sending and receiving keys
5122 as the protocol suggests. This has been fixed and will cause
5123 incompatibilities with older clients when sending private
5124 message encrypted with private message keys. Affected files
5125 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
5126 and various other in Irssi SILC Client.
5128 Added `responder' boolean argument to the functions
5129 silc_client_add_private_message_key[_ske] to indicate when
5130 the key is added as responder or initiator of the key
5133 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5135 * Removed the silc_ske_check_version function and created
5136 a SilcSKECheckVersion callback. Added also a function
5137 silc_ske_set_callbacks that is now used to set all SKE
5138 callbacks. The callback functions are not given to
5139 the SKE functions anymore, but this function is used to
5142 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
5144 * Added `silc_version' argument to the silc_client_alloc
5145 to define the version of the application for the library.
5146 The library will use the version string to compare it
5147 against the remote host's (usually a server) version
5148 string. Affected file lib/silcclient/silcapi.h
5150 * Added the KE protocol context to Key Agreement context
5151 in client library so that we can abort the SKE if it
5152 is in process when we get timeout. Affected file is
5153 lib/silcclient/client_keyagr.c.
5155 * Do not resolve the client ID forever if it returns in the
5156 first time that such client does not exist. This was done
5157 for example with private message. Affected file is
5158 lib/silcclient/client_prvmsg.c.
5160 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5162 * Do not add regex.h for WIN32. The affected file
5163 includes/silcincludes.h.
5165 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
5166 not work yet 100%. It generates the DLL's automatically
5167 when compiling with --with-win32 under cygwin.
5169 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5171 * lib/contrib/regex.c is not compiled on WIN32.
5173 * Added silc_net_get_socket_opt function to the
5174 lib/silcutil/silcnet.h.
5176 * Added includes/silcwin32.h for WIN32 specific includes
5179 * Do not use ptime structure or any of the posix process
5180 functions on WIN32 in lib/silccrypt/silrng.c.
5182 * Added silc_gettimeofday to provide generic function
5183 for struct timeval on all platforms. Added the function
5184 to lib/silcutil/silcutil.h.
5186 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5188 * Moved the lib/silccore/silcsockconn.[ch] to the utility
5189 library as they clearly belong there. As a plus side we
5190 can make the actual socket connection routines platform
5193 Added also new generic function silc_socket_read and
5194 silc_socket_write (that used to be silc_packet_[read/write].
5195 The implementation of these are platform specific.
5197 * Added WIN32 specific routines of silc_socket_[read/write]
5198 to lib/silcutil/win32/silcwin32sockconn.c.
5200 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5202 * Added preliminary support for native WIN32 compilation under
5203 cygwin (using the -mno-cygwin option for GCC) to the
5204 ./configure.in.pre. The --with-win32 now prepares the
5205 compilation for native WIN32.
5207 * Rewrote the SILC Scheduler interface in the file
5208 lib/silcutil/silcschedule.h. The scheduler is now context
5209 based and does not have anymore any global static scheduler.
5210 Moved the Unix scheduler to the lib/silcutil/unix/ directory
5211 and created lib/silcutil/win32 directory for WIN32 based
5214 * Added Unix specific network routines to the
5215 lib/silcutil/unix/silcunixnet.c and the old
5216 lib/silcutil/silcnet.c includes now only generic routines.
5218 Added WIN32 specific network routines to the
5219 lib/silcutil/win32/silcwin32net.c.
5221 * Added Unix specific utility functions from the
5222 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
5224 * Added WIN32 SILC Scheduler to the file
5225 lib/silcutil/win32/silcwin32schedule.c. The code is of course
5228 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5230 * Do not handle JOIN notify in the server if the target client
5231 is not registered (idata->registered == FALSE). The affected
5232 file is silcd/packet_receive.c.
5234 * Update the nickrec->founder in event_cumode in the Irssi SILC
5235 client. Affected file irssi/src/silc/core/silc-channels.c.
5237 * Fixed the CUMODE_CHANGE notify handling in the server when
5238 server and router are announcing their clients on channels.
5239 Now the mode changes are saved and notified correctly. The
5240 affected file is /silcd/packet_receive.c.
5242 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
5243 They really did not replace the cache entry in the ID Cache.
5244 Now they do that. Affected file silcd/idlist.c.
5246 * Fixed the KICK notify handling in the Irssi SILC client to
5247 update the channel records so that the kicked client does not
5248 appear to be on the channel. The affected file is
5249 irssi/src/silc/core/silc-channels.c.
5251 * Always update the conn->current_channel when executing command
5252 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
5254 * Fixed the KILL notify handling in Irssi SILC client to remove
5255 the killed client on all channels.
5257 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5259 * Fixed the silc_parse_command_line to remove extra spaces
5260 from the start and end of the arguments. Affected file is
5261 lib/silcutil/silcutil.c.
5263 * Cancel and free any active protocol in the function
5264 silc_server_close_connection. Affected file silcd/server.c.
5266 * Cancel and free any active protocol in the function
5267 silc_client_close_connction. Affected file is
5268 lib/silcclient/client.c.
5270 * Do not execute the KILL command for clients that are in
5271 history (ie. they are not in the network). Affected file is
5274 * Fixed KILL notify handling, client does not crash anymore.
5275 Affected file irssi/src/silc/core/silc-channels.c.
5277 * Reduced the default packet buffer size from 2048 to 1024 in
5278 lib/silccore/silcpacket.c.
5280 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5281 counter to the SKE context that is incresed when the SKE library
5282 performs async operation outside the library. If the outside
5283 process frees the SKE context and FREED status will be set
5284 and the library will detect after the sync operation that the
5285 libary is freed. The affected files are
5286 lib/silcske/silcske[_status].[ch].
5288 * Resolve the client entry information in the function
5289 silc_client_channel_message to assure that NULL pointer is not
5290 passed as client entry to the application. */
5292 * Fixed the task timeout calculation to assure that there is
5293 never negative timeouts. The affected file is
5294 lib/silcutil/silcschedule.c.
5296 * Fixed the channel user mode notification sending in server.
5297 It was sent point-to-point to the router (or to server by router)
5298 but it needs to be destined to a channel. The routines now
5299 supports sending the channel user mode notifys to the channels
5300 when announcing clients and channels. Affected files are
5301 silcd/server.c and silcd/packet_receive.c.
5303 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5304 It did not actually replace the old channel entry in the cache.
5305 Affected file lib/silcclient/client_notify.c.
5307 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5309 * Fixed a possible crash in silc_packet_send_prepare. It now
5310 assures always that there is enough space in the buffer and
5311 at the tail area of the buffer (for MAC).
5313 Fixed the inbound buffer reallocation in silc_packet_read.
5314 It was old code and did not handle the reallocation correctly.
5317 The affected file is lib/silccore/silcpacket.c.
5319 * Fixed buffer overflow in silc_parse_nickname in the file
5320 lib/silcutil/silcutil.c.
5322 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5324 * make install generates new server keys only if there is not
5327 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5329 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5330 Added check that if the NOREPLY is set then we will not send
5331 the away message. This avoids infinite loop of away messages
5332 if both clients are away. The affected file is
5333 lib/silcclient/client_prvmsg.c.
5335 * Fixed client crash if /NICK was given without arguments.
5336 Affected file lib/silcclient/command.c.
5338 * Server does not send the invite list in INVITE command back
5339 to the client if the list was not altered. Added this notion
5340 to the protocol spec as well. Affected file silcd/command.c.
5342 Fixed possible crash in INVITE command by checking the
5343 value of silc_server_get_client_route command.
5345 * Fixed the INVITE notify type handling. The arguments are now
5346 taken in correct order and client does not crash. The affected
5347 file is irssi/src/silc/core/silc-channels.c.
5349 Removed the "Inviting xxx to channel" message from the
5350 client library away and let the application handle it.
5351 Affected file lib/silcclient/command.c. Added that message
5352 to Irssi SILC client's message formats.
5354 * Fixed CMODE command crash in client. It now checks the
5355 amount of arguments correctly and does not crash. The affected
5356 file is lib/silcclient/command.c.
5358 * Do not create new channel automatically in silc_channels_join
5359 but check whether the channel by that name already exists.
5360 Affected file irssi/silc/core/silc-channels.c.
5362 * Do not send the SERVER_SIGNOFF to router if the disconnected
5363 entity was the router. Affected file silcd/server.c.
5365 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5366 SILC client as it was missing from there.
5368 Added the handling of the KICK notify to the Irssi SILC client
5369 as it was missing. Added "you have been kicked" message to
5370 Irssi SILC client's message modules formats.
5372 Added the handing of the KILL notify to the Irssi SILC client
5373 as it was missing. Added the kill message module formats
5376 The affected file is irssi/src/silc/core/silc-channels.c.
5378 * The router did not save the channel mode the server announced.
5379 Affected file silcd/packet_receive.c.
5381 * Fixed a possible crash in INFO command in server. If the
5382 server did not provide the server info it crashed. Affected
5383 file silcd/command.c.
5385 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5387 * Fixed the GETKEY command in the server to check also the
5388 global list. Otherwise the GETKEY would not work correctly
5389 in normal SILC server. Affected file silcd/command.c.
5391 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5393 * Fixed GETKEY crash, it crashed if the command did not succseed.
5395 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5397 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5398 is now real and not just an macro interface to GMP.
5400 Removed the entire GMP from the source tree and imported new
5401 NSS MPI library instead. Reason for removing GMP is that it is
5402 extremely large and compiles extremely slow. The NSS MPI
5403 is only a few files and compiles in less than 10 seconds.
5404 The speed is also about the same as GMP. The MPI is imported
5405 to lib/silcmath/mpi.
5407 If the system has GMP installed we will still use the GMP.
5408 If it is not then the NSS MPI will be compiled.
5410 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * Merged a long nickname (127 characters long) crash bugfix from
5413 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5415 * Merged a freed memory reference bugfix from Irssi CVS tree.
5416 Affected file irssi/src/core/commands.c.
5418 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5420 * Added the server's public key sving and verification to the
5421 server when performing the SKE. This was missing and the
5422 remote server's (or router's) public key was accepted without
5423 checking whether we have it previously or trust it at all.
5424 Affected file silcd/protocol.c.
5426 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5428 * Check in the silc_server_timeout_remote if protocol is active
5429 and make sure that the protocol's final callback is called so
5430 that all memory if freed. Affected file silcd/server.c.
5432 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5434 * silc_server_whois_send_reply crashed the server if the nickname
5435 was 127 characters long. Affected file silcd/command.c.
5437 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5439 * Added sanity check to the silc_server_new_client. If the hostname
5440 is provided inside username then check that the provided hostname
5441 really is the same as the resolved one. If the hostname was not
5442 resolved then check it from the public key. Affected file is
5443 silcd/packet_receive.c.
5445 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5446 if the server disconnected us and the connection is not valid
5447 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5449 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5450 the library to the lib/silcutil/silcutil.[ch].
5452 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5454 * Close log file after open. Affected file
5455 lib/silcutil/silclog.c.
5457 * Check whether sock == NULL in silc_client_send_packet and return
5458 if it is. Affected file lib/silcclient/silcclient.c.
5460 * Check rec->entry == NULL in the Irssi SILC Client before
5461 sending the channel message. Affecte file is
5462 irssi/src/silc/core/silc-servers.c.
5464 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5466 * Merged a splitted window bugfix from Irssi CVS tree. The
5467 affected file is irssi/src/fe-text/textbuffer-view.c.
5469 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5470 It did not print nickname.
5472 * Improved the distributions system a bit.
5474 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5476 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5477 irssi/src/fe-text/gui-window.c.
5479 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5480 to in-active server. The affected file is
5481 irssi/src/silc/core/client_ops.c.
5483 * Resolve the client in USERS command reply if the entry does
5484 not have username resolved. The affected file is
5485 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5486 command to WHOIS command to really resolve stuff. The USERS
5487 is not used any more in any critical section so WHOIS can
5488 be used even though it might be slower than IDENTIFY.
5490 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5493 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5495 * Changed the protocol API a bit more consistent in the
5496 lib/silccore/silcprotocol.[ch].
5498 * Changed the following headers to ROBODoc format:
5500 lib/silccore/silcpayload.h
5501 lib/silccore/silcprotocol.h
5502 lib/silccore/silcsockconn.h
5504 All core library headers are now formatted.
5506 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5508 * Fixed a bug in Irssi SILC client; do not show that you are
5509 server/router operator if you really are not. Affected file is
5510 irssi/src/silc/core/client_ops.c.
5512 * Renamed silc_command_free_payload to silc_command_payload_free.
5513 Affected file lib/silccore/silccommand.h
5515 * Added silcmath.h to include the prototoypes of various routines
5516 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5519 * Changed the following headers to ROBODoc format:
5521 lib/silccore/silcchannel.h
5522 lib/silccore/silccommand.h
5523 lib/silccore/silcid.h
5524 lib/silccore/silcidcache.h
5525 lib/silccore/silcmode.h
5526 lib/silccore/silcnotify.h
5527 lib/silccore/silcpacket.h
5528 lib/silcmath/silcmath.h
5530 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5532 * Added checking to the server code not to start the server if
5533 ciphers and stuff are not configured properly. Affected files
5534 silcd/serverconfig.[h] and silcd/server.c.
5536 * Changed the layout of the header files of the public interfaces
5537 in the SILC libraries. The new layout supports ROBODoc
5538 documentation tool (and some others) so that it is easy to create
5539 a library reference manual. All the other headers and source
5540 code must still follow the CodingStyle document. Also source
5541 code must not include these ROBODoc stuffs, only the headers.
5542 Furthermore, all public interface headers must now be named
5543 by using `silc' prefix, example: silcapi.h, silccipher.h.
5544 Some files were renamed due to this. All the other headers
5545 must not be used as public interfaces. I will update the
5546 CodingStyle document later. Changed following headers, so far:
5548 lib/silcclient/silcapi.h
5549 lib/silccore/silcauth.h
5550 lib/silccore/silcprivate.h
5551 lib/silccrypt/silcdh.h
5553 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5557 * Removed silc_client_packet_send_flush from the client library
5558 as it is not needed. Affected file lib/silcclient/client.[ch].
5560 * Added printing of message of unresolved authentication method
5561 to the Irssi SILC client. Added it to the module formats.
5562 Removed the same message from the client library.
5564 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * Added new distribution feature, DISTLABEL. Every distribution
5567 can define own preprocessor label that can be used in the
5568 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5569 file distributions, acconfig.h.pre and prepare.
5571 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5573 * Added Makefile.defines_int to include the actual definitions
5574 for Makefile.defines.in. Tested the new distribution system,
5575 created distributions and tested installation.
5577 * Added AWAY message printing to the Irssi SILC client. Added
5578 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5580 * Added SCONNECT command to call the SILC's CONNECT command.
5581 Cannot use CONNECT directly since Irssi uses that internally.
5582 Affected file irssi/src/silc/core/silc-servers.c.
5584 Added ACTION local command. It is same as ME command but takes
5585 the channel as mandatory argument.
5587 Rewrote some of the Irssi's help files to suite for SILC
5590 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5592 * Added Makefile.defines[.in] that should for now on be included
5593 in all Makefile.am file in the source tree. That file includes
5594 all common compilation definitions for SILC source tree.
5596 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5598 * Minor changes to the ./prepare script to change the package
5599 name according the distribution name to the configure.in.
5601 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5603 * Created new distribution system. Added file `distributions'
5604 that defines all the distributions that can be created out of
5605 the SILC source tree. The ./prepare script now reads that
5606 file to determine how to prepare the distributions. The
5607 first argument to the ./prepare is the name of the distribution
5608 and second is the version of the distribution. If given
5609 without arguments it creates the default (toolkit) distribution
5610 with the default version (defined in ./prepare).
5612 All Makefile.am files that are subject to the distributions
5613 are now named as Makefile.am.pre. These are ./Makefile.am
5614 and lib/Makefile.am. Others may be changed later.
5616 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5618 * Added invite list, ban list, some key management and connection
5619 error message printing to module formats in the Irssi SILC client.
5621 * Added new silc_client_set_away_message to set the away message
5622 that is back to the person who sent private message. The
5623 affected file lib/silcclient/silcapi.h and the
5624 lib/silcclient/client_prvmsg.c.
5626 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5628 * Fixed the private message sending in the Irssi SILC client,
5629 added local command KEY to the Irssi SILC client.
5631 Added key management and key agreement message formats to the
5632 irssi/src/fe-common/silc/module-formats.[ch].
5634 Added USERS (alias WHO) printing, server/router operator
5635 indication and LIST command printing to the module formats.
5637 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5639 * Fixed channel joining notify handling, cumode notify handling
5640 from Irssi SILC client.
5642 * Added SILC specific module-formats to the Irssi SILC client so
5643 that SILC specific message hilighting, colors etc is possible.
5644 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5646 Added channel mode, channel user mode, actions, notices,
5647 whois and whowas printing to the the module-formats.c.
5649 * Fixed a bug in channel deletion in the server. The channel
5650 is not left to the cache even if the channel founder auth mode
5651 is set when there are no users anymore on the channel. Affected
5652 file silcd/server.c.
5654 * The silc_net_localhost now resolves the entire hostname including
5655 the domain name. Affected file lib/silcutil/silcnet.c.
5657 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5659 * Changed the ask_passphrase client operation to be ascynchronous.
5660 It has now a completion callback and a context that the
5661 application must call after it has got the passphrase from
5662 the user. Affected files lib/silcclient/silcapi.h,
5663 lib/silcclient/protocol.c, lib/silcclient/command.c and
5666 Added SilcAskPassphrase callback that the application calls
5667 to deliver the passphrase to the library.
5669 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5670 The public key verification and especially a certificate
5671 verification is asynchronous procedure.
5673 Added new SILC_SKE_STATUS_PENDING status to indicate the
5674 request is pending and a callback will be called to finalize
5677 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5678 indicate that remote end did not send its public key (or
5679 certificate), even though we require it. Added check for this
5680 condition in the SKE. This was a security bug, now fixed.
5682 Defined new SilcSKEVerifyCbCompletion callback that is called
5683 when the verification process is completed.
5685 The affected files lib/silcske/silcske_status.h and
5686 lib/silcske/silcske.[ch].
5688 * Changed the verify_public_key client operation to be async
5689 as well. Defined SilcVerifyPublicKey callback that is used to
5690 indicate the success of the public key verification process.
5692 Changed the server and client to use the new async client
5695 * Changed the Irssi SILC client's internal scheduler to be called
5696 twice as many times as it used to be. As a result the client
5697 should be a bit faster now. Affected file is
5698 irssi/src/silc/core/silc-core.c.
5700 * Added support to Irssi SILC client of asynchronous public key
5701 verification and passphrase inquiry. Affected file is
5702 irssi/src/silc/core/silc-core.c.
5704 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5706 * Do not say "You have left channel %s" in client library.
5707 Moved it to the application. Affected files are
5708 lib/silcclient/command.c and silc/client_ops.c.
5710 * Fixed silc_client_get_clients. Command context was not
5711 duplicated and was freed memory in the callback. Affected
5712 file lib/silcclient/idlist.c.
5714 * Do not say "you are now talking..." on JOIN command in the
5715 client library. The appliation must handle it.
5717 * Do not say ".. changed topic to" in command reply in the
5718 client libary. The application must handle it.
5720 * Fixed TOPIC command sending in the client library.
5722 * Fixed a memory leak in silc_client_command_free in the file
5723 lib/silcclient/command.c.
5725 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5727 * Imported a modified version of Irssi client to the source tree.
5728 The Irssi will be used to create a new client called
5729 Irssi SILC. Imported to irssi/.
5731 Added silc_core_init_finish function to the Irssi. Affected
5732 file irssi/configure.in.
5734 A lot changes in the Makefile.ams around the irssi tree.
5736 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5738 * Do not rehash if the new size is same as the old size of the
5739 hash table, in the silc_hash_table_rehash*. The affected file
5740 lib/silcutil/silchashtable.c.
5742 * Replaced hash_table_del_by_context calls from the server
5743 (when channel->user_list and client->channels) to the
5744 hash_table_del as it is sufficient and faster.
5746 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5748 * Added silc_hash_table_list, silc_hash_table_get and the
5749 SilcHashTableList structure to provide an alternative way to
5750 traverse the hash table. The affected files are
5751 lib/silcutil/silchashtable.[ch].
5753 * Changed the server's idlist routines to use the hash table
5754 routines to optimize the code.
5756 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5758 * Replaced the client entry's `channel' list and channel entry's
5759 `user_list' list to hash tables for optimized lookup. Changed
5760 the code to use the hash table interface around the code.
5761 Affected file lib/silcd/idlist.[ch].
5763 * Added `auto_rehash' boolean argument to the function
5764 silc_hash_table_alloc to indicate whether the hash table should
5765 auto-rehash when it thinks is appropriate time. It will
5766 increase the hash table size if the there is twice as much
5767 entries in the table than the size of the table, and will
5768 decrease the size if there are twice as less entries than
5769 the size of the table.
5771 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5773 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5775 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5777 * silc_idcache_purge_by_context deletes the entry now by context
5778 as it is supposed to do. Affected file lib/silccore/idcache.c.
5780 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5781 client is not anymore valid (WHOWAS givens the info) and not
5782 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5784 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5786 * Removed the `data' and `data_len' arguments from the ID Cache
5787 interfaces and added `name' argument. ID Cache does not handle
5788 anymore the binary data only a names associated with given ID.
5790 * When hashing a Client ID with silc_hash_id the entire ID is
5791 not hashed anymore, instead only the hash of the Client ID is
5792 hashed. This way we can access the Client ID from the cache
5793 with Client ID but with the hash of the ID (which is a hash of
5794 the nickname) as well without any difference in performance.
5796 Added also silc_idcache_find_by_id_one_ext to do one on one
5797 searching when we have the actual ID. Added also function
5798 silc_hash_client_id_compare. The affected files are
5799 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5801 * When hashing the name associated with a ID it is always done
5802 in lowercase. This way we can access the cache without worrying
5803 about case-sensitivity, even though, for example nicknames are
5806 * Fixed a bug in server with channel message sending. It put
5807 wrong ID type as destination ID. The affected file
5808 silcd/packet_send.c.
5810 * silc_idcache_del_by_context now deletes from all hash tables
5811 by context. Affected file lib/silccore/idcache.c.
5813 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5815 * Changed the client library to use the new ID Cache interface.
5816 Changes around the source tree.
5818 * Added silc_hash_table_rehash_ext to rehash with specific
5819 hash function. Affected file lib/silcutil/silchashtable.[ch].
5821 * Added silc_hash_string_compare to compare two strings in the
5822 hash table. Affected file lib/silcutil/silcutil.[ch].
5824 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5826 * Added new function silc_idcache_del_by_context into the
5827 lib/silccore/idcache.[ch].
5829 * Changed the server's ID list routines to use the new ID Cache
5830 interface. Changes around the source tree.
5832 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5834 * Added silc_hash_table_del[_by_context]_ext functions in to the
5835 lib/silcutil/silchashtable.[ch].
5837 Removed silc_hash_table_find_all* routines and added new
5838 silc_hash_table_find_foreach to replace them.
5840 Added silc_hash_table_replace_ext function as extended
5841 replacing function. Separated the simple hash table interface
5842 from the extended hash table interface in the file
5843 lib/silcutil/silchashtable.h.
5845 * Fixed minor bugs and changed it to use some of the new
5846 hash table functions in lib/silccore/idcache.c
5848 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5850 * Added new function silc_hash_table_find_all to return all keys
5851 in the hash table by the specified key. As the hash table is
5852 collision resistant it also makes it possible to have several
5853 duplicate keys in the hash table. This function may be used to
5854 find all of the keys from the hash.
5856 Added user_context arguments to the SilcHashFunction,
5857 SilcHashCompare and SilcHashDestructor to deliver user specified
5860 Added new fuctions silc_hash_table_find[_all]_ext to do
5861 extended lookup with specified hash and compare functions and
5862 specified user contexts.
5864 Added new function silc_hash_table_add_ext to add the key
5865 with specified hash function and user context.
5867 Added new function silc_hash_table_foreach to traverse all
5868 entrys in the hash table. Added SilcHashForeach callback
5871 Added new function silc_hash_table_del_by_context to delete
5872 the entry only if the context associated with the key matches.
5874 Affected files are lib/silcutil/silchashtable.[ch].
5876 * Removed silc_hash_[server/client/channel]_id and added just
5877 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5878 silc_hash_id_compare to compare two ID's using as the hash table
5879 comparison function. Added also silc_hash_data to hash
5880 binary data and silc_hash_data_compare to compare it.
5882 * Removed silc_idlist_find_client_by_hash as it is not needed
5883 anymore. Affected file silcd/idlist.[ch].
5885 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5886 to use internally the SilcHashTable. The new ID Cache is a lot
5887 faster than the old one. Some of the ID Cache interface was also
5888 rewritten and obsolete and stupid functions were removed.
5890 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5892 * Added entry_count field to the SilcHashTable to keep the number
5893 of the entries in the table. Implemented the function
5894 silc_hash_table_rehash. Added new function
5895 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5897 Fixed a minor bug in silc_hash_table_free.
5899 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5900 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5901 into the lib/silcutil/silcutil.[ch].
5903 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5905 * Implemented a collision resistant hash table into the
5906 lib/silcutil/silchashtable[ch]. See the header and the source
5907 for the SilcHashTable API.
5909 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5911 * Merged dotconf version 1.0.2 into lib/dotconf.
5913 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5915 * Do not compile anything in lib/silcsim/* if the SIM support
5916 is not enabled. The tree should now compile without problems
5919 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5921 * Compiled the SILC under cygwin. Compiled and tested briefly
5922 without problems. More tests needed. The SIMs didn't compile
5925 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5927 * Fixed possible crash in silc_get_username in the
5928 lib/silcutil/silcutil.c.
5930 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5932 * Fixed a va_arg in silc/client_ops.c.
5934 * Oops, RC5 routines were named AES and caused some problems
5935 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5937 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5939 * Added new SilcIDIP structure into the lib/silccore/id.h and
5940 replaced the old `ip' fields from all SILC ID's to that type.
5941 This is a step towards IPv6 support.
5943 The silc_id_get_len takes now the ID as an extra argument.
5944 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5945 both IPv4 and IPv6 based ID's.
5947 The affected files are lib/silccore/id.[ch] and other files
5948 around the tree using these routines.
5950 * Removed the ID length arguments in server from various
5951 silc_server_send_notify_* routines -> they are not needed
5954 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5956 * Fixed memory leak in silc_encode_pem_file in the file
5957 lib/silcutil/silcutil.c.
5959 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5961 * Check minor version as well in the SKE. Affected files are
5962 silcd/protocol.c and lib/silcclient/protocol.c.
5964 * Added --identifier option to the server so that an identifier
5965 can be when creating the public key for the server. Affected
5966 file is silcd/silcd.c.
5968 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5969 lib/silccrypt/silcpkcs.c.
5971 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * Register default ciphers and stuff when using -C option with
5974 the server. Affected file sildc/silcd.c.
5976 * Put back the servers public key filename format, it is better
5977 than the new one. For now, the client keys are saved with the
5978 new filename format. The affected file silc/client_ops.c.
5980 * Implemented the Cipher API for the rest of the ciphers that
5981 did not implement it or implemented it the wrong way.
5983 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5985 * Register default ciphers and stuff when using the -S option
5986 in the client. Affected file silc/silc.c. Same also when
5987 creating new key pair with -C option.
5989 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5991 * Fixed the silc_verify_public_key client operation function to
5992 save the public keys differently. The fingerprint is now
5993 used as filename and not the hostname. This way also the
5994 client keys are saved uniquely and not with hostnames. The
5995 affected file is silc/client_ops.c.
5997 * Trimmed the silc_hash_fingerprint function to remove extra
5998 whitespaces from the end of the fingerprint. The affected
5999 file is lib/silccrypt/silchash.c.
6003 * Added silc_cipher_register_default function to register all
6004 default ciphers. It can be used when configuration files
6005 does not exist and the application does not want any specific
6006 ciphers in any specific order.
6008 The SilcDList is now used as silc_cipher_list dynamically
6009 allocated cipher list. Removed the static list all together
6010 and now all ciphers must be allocated to the dynamic list.
6011 The silc_cipher_alloc routine was changed to check only the
6014 All silc_cipher_* routines that used to return int returns
6017 The affected files lib/silccrypt/silccrypt.[ch].
6019 * The same thing was done to silc_hash_* as for silc_cipher_*
6020 routines. Affected files lib/silccrypt/silchash.[ch].
6022 * The same thing was done to silc_pkcs_* as for silc_cipher_*
6023 routines. Affected files lib/silccrypt/silcpkcs.[ch].
6024 Added also silc_pkcs_[un]register[_default] functions.
6025 Removed the data_context from the PKCS API.
6027 * Added silc_hmac_register_default function to register default
6028 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
6029 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
6030 to unregister all hmacs at once.
6032 * Register the default ciphers, hash functions, PKCSs and HMACs
6033 if client's configuration file does not exist. The affected
6036 * The client did not load the hash functions from the SIM
6037 modules at all. Added support for this. Affected file is
6038 silc/clientconfig.c.
6040 * When decoding public key with silc_pkcs_public_key_decode, check
6041 the supported algorithm only if PKCS are registered. Affected
6042 file lib/silccrypt/silcpkcs.c. The same was done with the
6043 silc_pkcs_private_key_decode.
6045 * Fixed the SILC List routines to keep the list always in order.
6046 It used to change the list's order when traversing the list but
6047 not it preserves the order. Affected file lib/trq/silclist.h.
6049 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6051 * Added the client library to use the SilcSocketConnection's
6052 reference counter (by silc_socket_dup) to prevent the bug that
6053 the socket object may be freed underneath async operation.
6055 * The name resolv library checking fixes in the configure.in.pre.
6058 * Created new version of the protocol drafts for future
6059 development. The -03 drafts are the ones that will be changed
6060 in the trunk now and the -02 will remain as they are.
6062 * Send list of CUMODE notifys to the router when announcing
6063 the channel users to the router. Affected file silcd/server.c.
6064 If the router receiving channel founder CUMODE for a channel
6065 that already has channel founder it will send CUMODE notify
6066 to the sender to remove the channel founder rights from the
6067 announced client. Affected file silcd/packet_receive.c.
6069 * The CUMODE notify may now use Server ID as well as the entity
6070 who changes the mode. Updated protocool specs.
6072 * Updated INSTALL and README files.
6074 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6076 * New web pages in the http://silc.pspt.fi. The pages was
6081 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6083 * Implemented the [DenyConnectin] config section in the server.
6084 Added silc_server_config_denied_conn to check whether incoming
6085 connection is denied. Affected file silcd/serverconfig.[ch].
6087 * Do not check the ports when checking the incoming configuration
6088 data if the port is 0, meaning any. Affected file is
6089 silcd/serverconfig.c.
6091 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6093 * Fixed buffer overflow in silc_string_compare in the file
6094 lib/silcutil/silcutil.c.
6096 * Fixed double free in silc_server_command_leave in the file
6099 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6101 * Fixed the version checking in the server. Affected file is
6104 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6106 * Fixed the configuration data fetching when accepting new
6107 connections in the server. Affected file silcd/server.c.
6109 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6111 * Added `sender_entry' argument to the function
6112 silc_server_packet_relay_to_channel so that we can check
6113 whether some destination actually belongs to the same route
6114 the sender belongs (ie, we must not resend the packet to the
6115 sender). Affected file silcd/packet_send.[ch].
6117 * Added `servername' field to the SilcClientEntry in the server
6118 to hold the name of the server where client is from. Affected
6119 file is silcd/idlist.h.
6121 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6123 * Moved the channel message encrypting in the router betwen
6124 router connections from silc_server_channel_message to the
6125 silc_server_packet_relay_to_channel since we want to check
6126 whether we have anybody channel before encrypting anything.
6127 Affected files silcd/packet_[receive/send].c.
6129 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6131 * Fixed the [AdminConnection] server config section to support
6132 multiple entries. Affected file silcd/serverconfig.c.
6134 * Added support into the server to check the validity of the
6135 incoming connection before executing any KE or authentication
6138 * The connection configuration is now saved to the KE and
6139 connection auth protocol contexts and not fetched anymore in
6140 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
6142 * The local hosts listenning address and port is also resolved
6143 now when starting the server. We want to have the socket object
6144 to include the real address and port for the listener. Added
6145 new function silc_net_check_local_by_sock into the files
6146 lib/silcutil/silcnet.[ch].
6148 * Fixed a broadcast bug in server -> do not broadcast if we
6151 * Fixed a routing bug. Do not route broadcast packets ever.
6152 Broadcast packets must be processed always and not routed since
6153 they may be destined to some other host than yourself and thus
6154 would get routed without no good reason. Affected file is
6157 * Added function silc_server_config_is_primary_route to check
6158 whether primary router connection has been configured (a router
6159 configuration that we are initiating). If there is not, we
6160 will assume that there is only two routers in the SILC network
6161 and we will use the incoming router connection as our primary
6162 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
6164 * Changed the order of the broadcasting. Broadcast _after_ the
6165 packet has been processed not before. Affected file is
6168 * Fixed a [ClientConnection] parsing bug. The port was never
6169 parsed correctly thus resulting to port 0. Affected file
6170 silcd/serverconfig.c.
6172 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
6173 argument and did not set the broadcast packet flag. Affected
6174 file silcd/packet_send.c. Fixed same bug in the function
6175 silc_server_send_notify as well.
6177 * If we receive NEW_ID packet for our own ID in the server, ignore
6180 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6184 * Removed the nickname from the Private Message Payload.
6185 Updated the code and the protocol specs.
6187 * Updated protocol specs for submitting to the IETF.
6189 * Tweaked the Random Number Generator a bit. Affected file
6190 lib/silccrypt/silcrng.c. Exported a new function
6191 silc_rng_[global]_add_noise which can be used to add more
6194 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6196 * Do not parse packets with different timeout when protocol
6197 is active -> may cause problem with rekey. Affected file
6200 * When server receives signoff notify it must not create
6201 new channel key if the client is on any channels since the
6202 sender of the signoff notify will create it.
6204 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6206 * Added printing of error messages during SKE protocol from the
6207 failure packet sent by server during SKE. Affected file
6210 * Removed the client's failure_callback handling with timeout
6211 and handle it immediately when received.
6213 * The SKE library returned wrong type in SUCCESS and FAILURE
6214 packets. They must be 32 bit MSB not 16 bit MSB.
6216 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6218 * Ok, rewrote the logic of the re-key and now it seems to work.
6219 I tested it on high traffic with frequent re-keys without
6220 problems. Added hmac_receive (and renamed hmac to hmac_send)
6221 in SilcClientConnection in lib/silcclient/client.h and
6222 in SilcIDListData in silcd/idlist.h. Also, removed the
6223 SilcPacketParserContext's cipher and hmac fields as they are
6224 not needed anymore and actually caused some problems when
6225 the ciphers and hmac's changed underneath the packet parser.
6227 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6229 * If re-key protocol is active then process the incoming packets
6230 synchronously since we must assure that icoming packets encrypted
6231 with the old key is processed before the new keys is set to
6232 use. This is true other packets than for REKEY packets.
6233 Affected file silcd/server.c. The same was done to client library
6234 as well, affected file lib/silcclient/client.c.
6236 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6238 * Fixed bug in client and server to accept the force send if
6239 the packet is send from silc_[server/client]_packet_process
6240 function. Otherwise the packets are never delivered, oops.
6242 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6244 * Disable force sending of packets when REKEY protocol is active.
6245 We must assure that no packet is sent directly when rekey is
6246 performed. All packets must be sent through packet queue.
6247 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
6248 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
6249 function is silc_[server/client]_packet_send_real to check
6252 * Replaced the SIM paths from example config files to
6253 /usr/local/modules. Also, make install creates now
6254 /usr/local/silc/logs directory to hold all the SILC server
6257 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6259 * Made the configure.in.pre work on Solaris. Patch by salo.
6261 * Made all ciphers compatible with non-x86 machines. Defined
6262 CBC mode macros into lib/silccrypt/ciphers_def.h.

6268 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6270 * When MAC computation fails the silc_packet_decrypt returned 0
6271 even though it was supposed to return -1. Fixed this. The
6272 affected file is lib/silccore/silcpacket.c.
6274 * Do not replace the config files in /etc/silc (in make install)
6275 if they already exist. Affected file ./Makefile.am.
6277 * Do not send re-key packets immediately but through packet queue.
6278 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6280 * Changed silc_net_check_host_by_sock to return FALSE if the
6281 IP/DNS could not be resolved. Though, it returns the IP address
6282 now even if it could not resolve it (but returns also FALSE).
6283 Affected file lib/silcutil/silcnet.[ch].
6285 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6287 * Added silc_pkcs_decode_identifier to decode the public key's
6288 identifier. Affected file lib/silccrypt/silpkcs.[ch].
6289 Added also silc_pkcs_free_identifier. Added also new context
6290 SilcPublicKeyIdentifier.
6292 * Added -S option to the silc client. It is used to dump the
6293 contents of the specified public key file.
6295 * Changed the PKCS api to return the public key length when
6296 setting the public key.
6298 * Fixed a fatal bug in the public and private key file loading.
6299 Affected file lib/silccrypt/silcpkcs.c.
6301 * Execute the packet parsing for client with zero (0) timeout
6302 if the protocol is active. Affected file silcd/server.c.
6304 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6306 * Made the key generation options to the silcd program. Added
6307 -C option, equivalent to client's option.
6309 * Added new [ServerKeys] config section to the server. It
6310 configures the server's public and private key.
6312 * Defined generic Public Key Payload into the protocol
6313 specification to send specific type of public keys and
6316 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6317 public key or certificate.
6319 * Implemented the GETKEY command to the server and to the
6320 client library and on user interface.
6322 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6324 * Made preliminary `make install' work.
6326 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6328 * Added SilcServerRekey context into silcd/idlist.h.
6330 * Added the PFS support as defined in the specification to the
6331 SKE protocol. Affected files lib/silcske/*.c.
6333 * Added `ske_group' field to the SilcServerRekey context to hold
6334 the number of the SKE group that is used with PFS in re-key.
6335 Affected file silcd/idlist.h.
6337 * Added PFS re-key support to the server. Affected file is
6340 * Added silc_protocol_cancel to cancel execution of the next
6341 state of the protocol. Affected file is
6342 lib/silccore/silcprotocol.[ch].
6344 * Added the re-key support with and without PFS to the client
6345 library. Re-key is performed once in an hour, by default.
6347 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6348 Added silc_client_rekey_callback and silc_client_rekey_final.
6349 Affected files are lib/silcclient/protocol.[ch] and
6350 lib/silcclient/client.[ch].
6352 * Removed the `hmac_key' and `hmac_key_len' fields from the
6353 SilcClientConnection structure; not needed. Affected file is
6354 lib/silcclient/client.h.
6358 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6360 * Do not ask whether user wants to use the negotiated private key
6361 for private messages, just use it. Affected file is
6362 silc/local_command.c.
6364 * Added `send_enc_key' and `enc_key_len' fields to the
6365 SilcIDListData structure since they are needed in the re-key
6366 phase. Affected file is silcd/idlist.[ch].
6368 * Implemented the simple re-key protocol into the server.
6369 Affected files silcd/server.c and silcd/protocol.[ch]. The
6370 re-key will be performed once in an hour, by default.
6372 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6373 Added silc_server_rekey, silc_server_rekey_callback and
6374 silc_server_rekey_final.
6376 * Removed Tunneled flag from the protocol. Updated the code
6377 and the specifications.
6379 * Adde `pfs' field to the SilcIDListData to indicate whether
6380 the PFS is to be performed in the re-key. Affected file is
6383 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6385 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6386 int64 of at least the xintXX size. If void * is less that 4
6387 bytes uint32 * will be used. Defined bool as boolean.
6389 * Changed _ALL_ unsigned long and unsigned int to uint32,
6390 unsgined short to uint16 in the source tree.
6392 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6393 not handle clients that has entry->data.registered == FALSE.
6394 They are not in the network anymore. Affected file is
6397 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6399 * Implemented the sending of the SERVER_SIGNOFF notify in the
6400 server. Affected file is silcd/server.c.
6402 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6403 Added also silc_notify_payload_encode_args into the
6404 lib/silccore/silcnotify.[ch].
6406 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6407 Affected file silcd/packet_receive.c.
6409 * Implemented the SERVER_SIGNOFF notify handling in the client
6410 library. Affected file lib/silcclient/client_notify.c. Also,
6411 implemnted the printing of the SERVER_SIGNOFF info to the
6412 application. Affected file silc/client_ops.c.
6414 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6415 if the deleting was successful. Affected file silcd/idlist.[ch].
6417 * Added support for public key authentication in the connection
6418 authentication protocol in the client library. Affected file
6419 lib/silcclient/protocol.c.
6421 * Changed the server's silc_idlist_get_clients_by_* interface
6422 to support already allocated array so that new entries may be
6423 added to pre-allocated array. Affected file silcd/idlist.[ch].
6424 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6425 and command replies.
6427 * All command reply functions in the server now calls the
6428 pending command callback even if error occured. This way the
6429 error will be delivered to the client as well. Affected files
6430 silcd/command.c and silcd/command_reply.c.
6432 * Fixed INFO command to return local server's info if no server
6433 was provided. Affected file lib/silcclient/command.c.
6435 * Removed RESTART command for good. Updated the code and the
6438 * Rewrote parts of the task system. It is a bit simpler now.
6439 Removed unsued task priorities. The affected files are
6440 lib/silcutil/silctask.[ch].
6442 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6444 * Moved the USERS printing from the library to the application.
6445 Affected files lib/silcclient/command.c and silc/client_ops.c.
6447 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6451 * Added channel key re-key support. The re-key is perfomed
6452 only by the router and is done once in an hour. Added `rekey'
6453 field to the SilcChannelEntry in the server. Affected files
6454 silcd/server.c and silcd/idlist.h.
6456 * Added silc_task_unregister_by_context into the file
6457 lib/silcutil/silctask.[ch].
6459 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6461 * Added SILC_UMODE_GONE mode to indicate when the client is not
6462 present in the SILC network. Added also support to the local
6463 command AWAY that will set this mode. Added support of showing
6464 "xxx is gone" in WHOIS command. The USERS command shows the
6465 gone status as well.
6467 * Fixed setting server and router operator privileges in the
6468 server's UMODE command. Affected file silcd/command.c.
6470 * Merged the SKE KE1 and KE2 payloads into one payload. The
6471 new KE payload is equivalent to the old KE2 payload.
6473 Cleaned up the SKE Start Payload parsing. It now uses the
6474 simple buffer unformatting to do the parsing. A lot faster
6477 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6478 to the SKE that is used to indicate whether both of the SKE
6479 parties should perform authentication. By default only the
6480 responder performs authentication. By setting this flag also
6481 the initiator must do authentication. By default it is unset
6482 since in normal SKE case, client to server connection, only
6483 the responder should do authentication. When doing SKE between
6484 two clients both should perform authentication. Updated the
6485 code and the protocol specs.
6487 * A little fix to IDENTIFY command in the server. Search the
6488 client first by hash not nickname. Affected file is
6491 * Fixed the silc_client_close_connection to support closing
6492 the client to client connections wihtout deleting too much
6493 data. Affected file lib/silcclient/client.c.
6495 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6496 are received if protocol used to be active but is not anymore
6497 the application would crash due to NULL pointer dereference.
6498 Affected files silcd/server.c and lib/silcclient/client.c.
6500 * Added `hash' field to the SilcClientConnection to include
6501 the hash function negotiated in the SKE protocol.
6503 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6504 to set the channel founder authentication data. A client can
6505 claim the founder rights later by providing the authentication
6506 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6507 This way the channel founder can regain the channel founder
6508 privileges even it is left the channel. This works only on
6509 local server and the client must be connected to the same
6510 server to be able to regain the founder rights. Updated the
6511 protocol specs accordingly.
6513 Added support to the CMODE command in the client to set the
6514 founder auth data. Read the README to see how to set it.
6516 Added support to the CUMODE command to claim the founder
6517 rights. Read the README to see how to do it.
6519 Added support for the founder authentication to the Channel
6520 Entry in the server. Affected file silcd/idlist.h.
6522 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6523 server's CMODE command. Affected file silcd/command.c.
6525 * Added the following new functions into lib/silccore/silcauth.[ch]:
6526 silc_auth_get_method and silc_auth_get_data.
6528 * The server now saves the remote hosts public key to the
6529 SilcIDListData pointer. Affected file silcd/protocol.c.
6531 * The normal server now does not remove the channel entry from
6532 the cache if the founder authentication data is set. It used
6533 to remove it if the founder was the last one on the channel on
6534 the server and left the channel. The auth data is saved and
6535 if the channel is re-joined later the old entry is used with
6536 the old auth data. Affected files silcd/command_reply.c and
6539 * Removed the `pkcs' field from the SilcIDListData structure
6540 in the server; it is not used. Affected file silcd/idlist.h.
6542 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6544 * Fixed packet processing on slow links. Partial packets were
6545 never re-processed because the incoming data buffer was cleared
6546 by the application. Application must not directly clear the
6547 sock->inbuf, the packet processing routines handle it. Fixed
6548 this in client library and in server.
6550 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6552 * Fixed the WHOIS and IDENTIFY send reply function to really
6553 check whether to send list or just one entry. Affected file
6556 * Cleaned up the LEAVE command's channel key distribution. The
6557 affected file silcd/command.c.
6559 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6560 can enforce the channel mode as well. In that case the ID
6561 includes the ID of the server. The code now enforces the
6562 mode change if the router have different mode than the server.
6564 * The notify client operation with CMODE_CHANGE notify can now
6565 return NULL client_entry pointer if the CMODE was not changed
6566 by client. Application must check for this.
6568 * Added <Server ID> argument to INFO command to support server
6569 info fetching by Server ID.
6571 * Added silc_server_announce_get_channel_users to get assembled
6572 packets of channel users of the specified channel. Affected
6573 file silcd/server.[ch].
6575 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6576 was freed underneath the ID Cache.
6578 * Re-announce clients when the server received CHANNEL_CHANGE
6579 notify from the router. Affected file silcd/packet_send.c.
6581 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6583 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6584 crashed since it did not handle the fact that there is no cipher
6585 called "3" and didn't check the error condition. Now fixed.
6587 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6588 flag. It can be used to send message requests.
6590 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6592 * Implemented the RESTART command in the client.
6594 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6595 notice type messages. Added notice printing to the user
6598 * The channel keys are not re-generated if the channel's mode
6599 is PRIVKEY, ie private key on the channel exists. Affected
6600 files silcd/server.c and silcd/command.c.
6602 * Fixed a little bug in channel message delivery when channel
6603 private keys are set in the server. Affected file is
6604 silcd/packet_send.c.
6606 * Changed the setting on channel->on_channel = TRUE from the
6607 silc_client_save_channel_key to the JOIN command reply. The
6608 key payload is not received if the private channel key is set.
6609 Affected file lib/silcclient/command_reply.c and the
6610 lib/silcclient/client_channel.c.
6612 * When the CMODE_CHANGE notify is sent and the channel private
6613 key mode is removed the channel key must be re-generated in
6614 other cells as well. Added this support for the router in the
6615 silcd/packet_receive.c.
6617 * Added new local command NOTICE to send notice message on
6618 channel. Affected file silc/local_command.[ch].
6620 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6622 * Added new local command ME to the client. It is used to send
6623 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6624 some action. Affected file silc/local_command.[ch].
6626 * Changed channel_message and private_message client operations
6627 to deliver the message flags to the application. Added also
6628 the `flags' arguments to the silc_client_send_channel_message
6629 and silc_client_send_private_message functions. Affected file
6632 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6634 * Redefined the Private Message Payload to support private message
6635 keys and to support the new private message flags. Updated
6636 the protocol specs. Flags makes it possible to have for example
6637 CTCP style messages.
6639 * Added new type SilcPrivateMessagePayload and defined an API
6640 for it in the lib/silcclient/silcprivate.[ch].
6642 * Tested private message private keys successfully. Tested the
6643 private message key set, unset and list commands with the new
6646 * Redefined the Channel Message Payload to include the channel
6647 message flags (equal with private message flags) to support
6648 for example CTCP style messages.
6650 * Defined some of the message (for channel and private message)
6651 flags. Updated the protocol specs and added the flags to the
6652 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6654 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6656 * Added SilcKeyAgreementStatus type to the key agreement routines
6657 to indicate the current status and error if one occured.
6658 The status types are defined in the lib/silcclient/silcapi.h.
6660 * Added new local command KEY that is used to set and unset private
6661 keys for channels, set and unset private keys for private messages
6662 with remote clients and to send key agreement requests and
6663 negotiate the key agreement protocol with remote client. The
6664 key agreement is supported only to negotiate private message keys,
6665 it currently cannot be used to negotiate private keys for channels,
6666 as it is not convenient for that purpose.
6668 * Fixed a minor pending callback setting bug in the function
6669 silc_client_get_client_by_id_resolve, now the function works.
6670 Affected file lib/silcclient/idlist.c.
6672 * Added function silc_net_get_local_port to get local bound
6673 port by socket. Added to lib/silcutil/silcnet.[ch].
6675 * Added `sockets' and `sockets_count' fields to the SilcClient
6676 object. They hold the sockets of the listenning sockets in
6677 the client. Listenning sockets may be for example the key
6678 agreement server. Affected file lib/silcclient/client.[ch].
6679 Added functions the silc_client_add_socket and the
6680 silc_client_del_socket. They are exported to the application
6683 * Added ~./silc/clientkeys to support other client's public keys.
6685 * Renamed verify_server_key client operation to verify_public_key
6686 and added one argument to indicate the type of the connection
6687 (server, client etc.).
6689 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6691 * Added silc_server_connection_auth_request to handle the
6692 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6693 silcd/packet_receive.[ch].
6695 * Added silc_server_send_connection_auth_request into the
6696 silcd/packet_send.c to send the connection auth request packet.
6698 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6701 * Fixed the public key authentication in responder side in the
6702 server. The `auth_data' pointer includes the SilcPublicKey
6703 not the path to the public key. Affected file silcd/protocol.c.
6705 * Implemented the public key authentication in the initiator side
6706 in the server. Affected file silcd/protocol.c.
6708 * Removed the [RedirectClient] config section from the server
6709 configuration. Is not needed and I don't want to implement it.
6711 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6713 * Cleaned up the CMODE command in the server. It now works
6714 correctly and supports all the modes defined in the protocol.
6715 Affected file is silcd/command.c.
6717 * Added `hmac_name' field to the SilcChannelEntry in the server
6718 to hold the default HMAC of the channel. It can be set when
6719 creating the channel (with JOIN command). Affected files
6722 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6723 type to indicate the change of the current cipher and hmac
6724 on the channel. Client can safely ignore the <cipher> argument
6725 (if it chooses to do so) since the CHANNEL_KEY packet will
6726 force the channel key change anyway. The <hmac> argument is
6727 important since the client is responsible of setting the new
6728 HMAC and the hmac key into use.
6730 * Fixed the CMODE command in the client library as well.
6732 * Tested CMODE command in router environment successfully.
6734 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6736 * Show the version of the remote client (or server) when connecting
6737 to the server. It is logged to the log file. Affected file
6738 is silcd/protocol.c.
6740 * Fixed the KILLED notify handling in the client library. The
6741 client must be removed from all channels when receiving the
6744 Also, do not remove the client entry when giving the KILL
6745 command but when the KILLED notify is received.
6747 * Removed silc_idlist_find_client_by_nickname from the server.
6748 Not needed anymore. Affected files silcd/idlist.[ch].
6750 * Implemented the CHANNEL_CHANGE notify type handling to the
6751 server. Affected file silcd/server.c.
6755 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6757 * Added silc_server_send_notify_invite to send the INVITE
6758 notify between routers.
6760 * Implemented the INVITE command correctly to the server.
6762 * Implemented the INVITE notify type handling in the server.
6764 * Implemented the INVITE command to the client library and on the
6767 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6769 * Added function silc_server_get_client_resolve to find the
6770 client entry by ID from all ID lists and then resolve it
6771 (using WHOIS) if it cannot be found. Affected file is
6774 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6776 * Implemented the BAN command to the client library.
6778 * The JOIN command in the server now checks the invite list
6781 * Changed the silc_command_reply_payload_encode_va and the
6782 silc_command_payload_encode_va to support that if argument is
6783 NULL it ignores and checks the next argument. Affected file
6784 lib/silccore/silccommand.c.
6786 * Added silc_server_send_notify_ban to send the BAN notify
6787 type between routers.
6789 * Chaned the silc_notify_payload_encode to support that if
6790 argument is NULL it ignores and checks the next argument.
6791 Affected file lib/silccore/silcnotify.c.
6793 * Tested ban lists in router environment successfully.
6795 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6797 * Implemented BAN command to the server, in silcd/command.[ch].
6799 * Removed the BAN and INVITE_LIST modes from the CMODE command
6802 * Added function silc_string_match to regex match two strings.
6803 Affected files lib/silcutil/silcutil.[ch].
6805 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6807 * Redefined parts of the SilcChannelEntry in the server to support
6808 the new ban and invite lists.
6810 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6812 * Redefined the INVITE command. The same command can be used to
6813 invite individuals to the channel but also to manage the invite
6814 list of the channel (to add to and remove from the invite list).
6815 Updated the protocol specs.
6817 * Added new command SILC_COMMAND_BAN that can be used to manage
6818 the ban list of the channel. Updated the protocol specs.
6820 * Removed the channel modes: the SILC_CMODE_BAN and the
6821 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6822 in the CMODE command. The equivalent features are now available
6823 using INVITE and BAN commands. Updated the protocol specs.
6825 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6826 in the network about change in the current ban list. The notify
6827 type is not used by the client.
6829 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6830 support the invite lists.
6832 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6834 * Added new function silc_string_regexify that converts string
6835 including wildcard characters into regex string that can
6836 be used by the GNU regex library. Added into the file
6837 lib/silcutil/silcutil.[ch].
6839 Added silc_string_regex_combine to combine to regex strings
6840 into one so that they can be used as one regex string by
6841 the GNU regex library. Added into the file
6842 lib/silcutil/silcutil.[ch].
6844 Added silc_string_regex_match to match two strings. It returns
6845 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6847 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6849 * Imported GNU regex to the soruce tree into lib/contrib.
6850 Fixed some compiler warning from the regex.c.
6852 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6854 * Fixed MOTD command in the server to work in router environment.
6856 * Fixed the MOTD command in the client library to support
6857 the server argument in the command.
6859 * Added `nickname_len' argument to the silc_idlist_add_client
6860 in the server, as the `nickname' argument may be binary data
6863 * Added silc_idlist_get_channels to return all channels from
6866 * Implemented LIST command to the server. Affected file is
6869 * Implemented the LIST command to the client library and on the
6872 * Added [<user count>] argument to the LIST command reply.
6873 With private channels the user count is not shown.
6875 * Updated TODO and README.
6877 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6879 * The client entry's data.registered must be TRUE even with
6880 global client entry on global client list. The data.registered
6881 is used to check whether the client is anymore in the network,
6882 for example with WHOWAS command so it must be valid.
6884 * Fixed the WHOWAS command in the server. It now actually works
6885 in router environment. Added function into silcd/command_reply.c
6886 silc_server_command_reply_whowas_save.
6888 * Added silc_idlist_purge function to the silcd/idlist.c
6889 to periodically purge the ID Cache.
6891 * Fixed INFO command in the server. It works now in router
6892 environment. Added <server name> argument to the INFO command
6893 reply. Updated the protocol specs.
6895 * Fixed minor bug in silc_idcache_purge to not purge if the
6896 expire value is zero.
6898 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6899 they were buggy because of the WHOWAS information.
6901 * Fixed local command MSG to handle the async resolving of
6902 the remote client properly. It used to fail the first MSG.
6903 Affected file silc/local_command.c.
6905 * Added `data_len' field to SilcIDCache context.
6907 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6909 * Update TODO. Todo in commands in the server.
6911 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6913 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6914 used by routers as broadcast packet to inform other routers
6915 about the changed user mode.
6917 Implemented the notify handling in the server. Affected file is
6918 silcd/packet_receive.c. Added the function
6919 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6921 * Added new generic Channel Payload and deprecated the New Channel
6922 Payload. The New Channel Payload is now the generic Channel
6925 * Added new argument `mode' to the silc_server_send_new_channel
6926 as it is required in the Channel Payload now.
6928 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6929 and created a new and real SilChannelPayload to represent the
6930 new generic Channel Payload. Implemented the encode/decode
6931 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6933 * Added silc_server_get_client_channel_list to return the list
6934 of channels the client has joined for WHOIS command reply.
6935 Affected file silcd/server.[ch].
6937 * Implemented the channel list sending in the WHOIS command reply
6938 in server and in the client.
6940 Implemented the channel list displaying on the user interface
6941 as well. Affected file silc/client_ops.c.
6943 * Added silc_channel_payload_parse_list to parse list of Channel
6944 Payloads. It returns SilcDList list of SilcChannelPayloads.
6945 Client for example can use this function to parse the list of
6946 channels it receives in the WHOIS command reply. The caller
6947 must free the list by calling silc_channel_payload_list_free.
6948 Affected files lib/silccore/silcchannel.[ch].
6950 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6952 * Added one new argument <user mode> to the WHOIS command reply
6953 to return the mode of the user in SILC. Updated the protocol
6956 Implemented it to the server and client.
6958 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6960 * Fixed the mode printing on the user interface on joining.
6961 Affected file silc/client_ops.c.
6963 * Implemented the UMODE command and user modes in general to the
6964 client library and to the user interface.
6966 * Implemented the UMODE command to the server.
6968 * The server now sends UNKNOWN_COMMAND error status if client sends
6969 unknown command. Affected file silcd/command.c.
6971 * All server commands now handle the command identifier the right
6972 way when sending the command reply to the client. The client can
6973 use to identify the command replies with the identifier.
6975 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6977 * Added silc_server_get_client_route to resolve the route to
6978 the client indicated by the client ID. Affected file is
6981 * Added silc_server_relay_packet as general function to relay
6982 packet to arbitrary destination. This deprecates functions
6983 like _send_private_message_key, _relay_notify etc. Affected
6984 file is silcd/packet_send.[ch].
6986 Removed silc_server_send_key_agreement,
6987 silc_server_send_private_message_key and
6988 silc_server_packet_relay_notify functions from the file
6989 silcd/packet_send.[ch].
6993 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6994 server. Affected file silcd/packet_receive.[ch].
6996 * Implemented the KILL command to the client. Implemented the
6997 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6998 Affected files lib/silcclient/command[_reply].c and
6999 lib/silcclient/client_notify.c. Implemented the KILL notify
7000 printing in the user inteface.
7002 * Fixed a lot silc_parse_nick memory leaks from the client
7003 library in the file lib/silcclient/command.c.
7005 * Changed the silc_server_send_notify_on_channels's `sender'
7006 argument from SilcSocketConnection to SilcClientEntry to
7007 check the sender as entry and not as connection object and not
7008 to send to the client provided as argument. The affected file
7009 is silcd/packet_send.[ch].
7011 * The notify packets that are destined directly to the client used
7012 to not to be processed by the server. Now changed that and the
7013 server processes all notify packets. After relaying the packet
7014 to the client the notify packet is processed in the server.
7016 * The silc_server_free_client_data now checks whether there is
7017 pending outgoing traffic for the client and purges the data to
7018 the network before removing the client entry.
7020 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7022 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
7023 an client is killed from the SILC Network. Updated the protocol
7026 Added new function silc_server_send_notify_killed to the
7027 silcd/packet_send.[ch].
7029 * Added function silc_server_packet_relay_notify to relay notify
7030 packets that are destined directly to a client. In this case
7031 the server does not process the notify packets but merely relays
7032 it to the client. Affected file silcd/packet_send.[ch].
7034 Added also silc_server_packet_process_relay_notify to check
7035 whereto relay the notify. Affected file is
7036 silcd/packet_receive.[ch].
7038 * Implemented the KILL command to the server.
7042 * Added the backup schema desgined last fall to the protocol
7043 specs for everyone to see. The specification is in the
7044 *-spec-xx.txt draft and the packet type definitions for the
7045 backup routers is in *-pp-xx.txt draft. Thusly, added also
7046 new packet type SILC_PACKET_CELL_ROUTERS.
7048 * A big security problem in the implementation discovered. The
7049 signoff of an client did not cause new channel key generation
7050 which it of course should've done. The channel keys must be
7051 always re-generated when client leaves (or signoffs) the channel.
7052 The silc_server_remove_from_channels funtion now handles
7053 the channel key re-generation.
7055 * Added `sender' argument to the silc_server_send_notify_on_channels
7056 to not to send the client provided as argument. Affected file
7057 silcd/packet_send.[ch].
7059 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7061 * Implemented OPER and SILCOPER commands into the server and
7064 * Added silc_auth_verify and silc_auth_verify_data to verify
7065 the authentication directly from the authentication payload.
7066 It supports verifying both passphrase and public key based
7067 authentication. Affected file lib/silccore/silcauth.[ch].
7069 * Added `hash' field to the SilcIDListData structure. It is the
7070 hash negotiated in the SKE protocol. Affected file is
7073 * Slight redesigning of the SilcAuthPayload handling routines.
7074 Do not send SilcPKCS but SilcPublicKey as argument.
7076 * Implemented the public key authentication support to the
7077 serverconfig. The public key is loaded from the provided path
7078 and saved as authentication data to void * pointer. Thus,
7079 changed the unsigned char *auth_data to void *auth_data;
7081 * Fixed SHUTDOWN command to send the reply before the server
7082 is shutdown. :) Affected file silcd/command.c.
7084 * Fixed fatal bug in CONNECT command. The hostname was invalid
7085 memory and server crashed. Affected file silcd/command.c.
7087 * Fixed fatal bug in CLOSE command. The server_entry became
7088 invalid but was referenced later in the command. Affected file
7091 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7093 * Fixed fatal bug in failure packet handling. Server ignored
7094 the failure and thus crashed when it came.
7098 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7100 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
7101 that the command may be executed only once in (about) 2 seconds.
7102 The old SILC_CF_LAG flag is same but allows command bursts up
7103 to five before limiting.
7105 Added the support for CF_LAG and CF_LAG_STRICT flags to the
7106 server code. Various commands now includes the CF_LAG_STRICT
7107 flag to disallow any kind of miss-use of the command.
7109 * Fixed the silc_buffer_unformat to not to allocate any data
7110 if the length of the data is zero. It used to allocate the
7111 length + 1. Affected file lib/silcutil/silcbuffmt.c.
7113 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7115 * Changed the format of AdminConnection configuration section
7116 in the server. Added username of the admin to the format.
7117 Affected files silcd/serverconfig.[ch].
7119 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
7120 to return admin configuration data by host, username and/or
7123 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7125 * Implemented WHOWAS command to the server. Added the functions:
7127 silc_server_command_whowas_parse,
7128 silc_server_command_whowas_send_reply,
7129 silc_server_command_whowas_from_client and
7130 silc_server_command_whowas_from_server
7132 * Added <Client ID> argument to the WHOWAS command reply. Updated
7133 the protocol specs accordingly.
7135 * Implemented WHOWAS command and command_reply to the client
7138 Implemented the WHOWAS printing on the user interface.
7140 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7142 * Added new argument to the WHOWAS command reply, the real name.
7143 It is an optional argument. Updated the protocol specs.
7145 * Added SilcIDCacheDestructor callback that is registered when
7146 the SilcIDCache is allocated. The callback is called when
7147 an cache entry in the ID Cache expires, or is purged from the
7148 cache. Added into lib/silccore/idcache.[ch].
7150 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
7151 to destruct the client entries when the cache entry expires.
7152 Other ID Cache's in server and in the client library ignores
7155 * If the ID Cache entry's `expire' field is zero then the entry
7156 never expires. Added boolean `expire' argument to the
7157 silc_idcache_add function in the lib/silccore/idcache.[ch].
7158 If it is TRUE the default expiry value is used.
7160 * Added silc_server_free_client_data_timeout that is registered
7161 when client disconnects. By default for 5 minutes we preserve
7162 the client entry for history - for WHOWAS command.
7164 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7166 * Added support to the server to enforce that commands are not
7167 executed more than once in 2 seconds. If server receives
7168 commands from client more frequently, timeout is registered
7169 to process the commands. Affected file silcd/command.c.
7170 Added new function silc_server_command_process_timeout.
7172 * Changed NICK_NOTIFY handling in client library to check that
7173 if the client's nickname was changed, so there is no need to
7174 resolve anything from the server.
7176 * Removed error printing from the WHOIS and IDENTIFY commands.
7177 If error occurs then it is ignored silently in the client library.
7178 The application, however, may map the received error to
7179 human readable error string. The application currently maps
7180 the NO_SUCH_NICKNAME error to string.
7182 * Made the command status message public to the application. Moved
7183 them from lib/silcclient/command_reply.c to
7184 lib/silcclient/command_reply.h. The application can map the
7185 received command status to the string with the
7186 silc_client_command_status_message function.
7188 * Added check to the server to check that client's ID is same
7189 as the Source ID in the packet the client sent. They must
7192 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7194 * Added dist-bzip hook to the Makefile.am to make bzip2
7195 compressed distributions.
7197 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7199 * Server now enforces the maximum length for the nickname and
7200 the channel as protocol specification dictates. 128 bytes for
7201 nickname and 256 bytes for channel name.
7203 * Moved the WHOIS printing to the application. The client libary
7204 does not print out the WHOIS information anymore, the application
7205 must do it. Renamed silc_client_command_reply_whois_print to
7206 the silc_client_command_reply_whois_save.
7208 The client's idle time is also sent to the application now, and
7209 the idle is shown on screen.
7211 * Added silc_client_command_reply_identify_save to save the
7212 received IDENTIFY entries.
7214 * Do not check for channel private keys in message sending and
7215 reception if the channel does not have the PRIVKEY mode set.
7216 Affected file lib/silclient/client_channel.c.
7218 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7220 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
7221 just surfaced after chaning the JOIN procedure.
7223 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7225 * Added silc_client_get_clients_by_list to get client entries
7226 from Client ID list, that is returned for example by JOIN
7227 and USERS command replies. The application should use this
7228 function for example when JOIN command reply is received to
7229 resolve the clients already on the channel (library does not
7230 do that anymore as USERS command reply is not used in the JOIN
7231 procedure anymore). Affected files lib/silcclient/silcapi.h and
7232 lib/silcclient/idlist.c.
7234 * JOIN command reply and USERS command reply returns now SilcBuffer
7235 pointers instead of unsigned char pointers when returning
7236 the client list and mode list.
7238 * Added <Client ID> argument to the JOIN command reply, mainly
7239 for the server to identify for which client the command was
7240 originally sent. Updated protocol specs accordingly.
7242 * Added SilcDlist private_key pointer to the SilcChannelEntry
7243 in the client to support the channel private keys. Affected
7244 file is lib/silcclient/idlist.h.
7246 * Added SilcChannelPrivateKey argument to the function
7247 silc_client_send_channel_message so that application can choose
7248 to use specific private ke if it wants to. If it is not provided,
7249 the normal channel key is used, unless private keys are set.
7250 In this case the first (key that was added first) is used
7251 as the encryption key.
7253 * Implemented the support for channel private key handling.
7254 Implemented the following functions:
7256 silc_client_add_channel_private_key,
7257 silc_client_del_channel_private_keys,
7258 silc_client_del_channel_private_key,
7259 silc_client_list_channel_private_keys and
7260 silc_client_free_channel_private_keys
7262 Affected file lib/silcclient/client_channel.c.
7264 * Added the support for the private keys in the channel message
7265 sending and encryption and in the message reception and
7266 decryption. Affected funtions are
7267 silc_client_send_channel_message and silc_client_channel_message.
7269 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7271 * Added SKE's key verify callback to the client library's
7272 KE protocol context. Affected files lib/silcclient/protocol.[ch].
7274 * Removed the statement that server (or router) must send USERS
7275 command reply when joining to the channel so that the client
7276 knows who are on the channel. Instead, the client list and
7277 client's mode list is now sent in the JOIN command reply to the
7278 client who joined channel. This is better solution.
7280 * Added function silc_server_get_users_on_channel and function
7281 silc_server_save_users_on_channel to the silcd/server.[ch].
7283 * Removed function silc_server_command_send_users from the
7286 * Do not show topic on the client library anymore. The topic is
7287 sent in the command reply notify to the application and the
7288 application must show the topic now.
7290 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7292 * Added client searching by nickname hash into the IDENTIFY and
7293 WHOIS commands in the server as they were clearly missing from
7294 them. Affected file is silcd/command.c.
7296 * Fixed a bug in private message receiving in the client library.
7297 The remote ID was freed and it wasn't supposed, now it is
7300 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7302 * Minor fix to the channel payload; allocate the data area, as it
7303 needs to be of specific length.
7305 * If the key agreement port is zero then the operating
7306 system will define the bound port. Affected files are
7307 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7309 * Added new function silc_channel_payload_decrypt into the file
7310 lib/silccore/silcchannel.[ch].
7312 * Moved the channel message etc, check from silc_packet_decrypt
7313 to applications. The library calls now a generic
7314 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7315 when the packet is either normal or special. This was done to
7316 allow more wide range of checking that was not allowed when
7317 the code was in library. Now applications can do virtually any
7318 checks to the packet and return to the library the decision how
7319 the packet should be processed. Affected files are
7320 lib/silccore/silcpacket.[ch].
7322 Added silc_server_packet_decrypt_check to the server and
7323 silc_client_packet_decrypt_check to the client library.
7325 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7326 to send with specified source and destination information.
7328 * Channel message delivery between routers was broken after the
7329 channel key distribution was fixed earlier. The channel key
7330 was used be to distributed to other routers as well which is not
7331 allowed by the protocol. Now this is fixed and channel keys
7332 really are cell specific and the channel message delivery between
7333 routers comply with the protocol specification.
7335 * Fixed various commands in server to check also the global list
7336 for the channel entry and not just the local list. The affected
7337 file silcd/command.c.
7339 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7341 * Added assert()s to buffer formatting and unformatting routines
7342 to assert (if --enable-debug) when error occurs. Affected
7343 file: lib/silcutil/silcbuffmt.c.
7345 * Changed to auto-reconnect to check whether the remote host is
7346 router and register the re-connect timeout if it is. It used
7347 to check that whether we are normal server, but router must do
7348 auto-reconnect with another router as well. Affected file
7351 * Removed the [<key len>] option from CMODE command as the cipher
7352 name decides the key length, nowadays. See the defined ciphers
7353 from the protocol specification.
7355 * Added [<hmac>] option to the CMODE command to define the HMAC
7356 for the channel. Added SILC_CMODE_HMAC channel mode.
7358 * Added [<hmac>] option for the JOIN command so that user can
7359 select which HMAC is used to compute the MACs of the channel
7362 * Added Hmac field to the Channel Message Payload. The integrity
7363 of plaintext channel messages are now protected by computing
7364 MAC of the message and attaching the MAC to the payload. The
7365 MAC is encrypted. Now, it is clear that this causes some
7366 overhead to the size of the packet but rationale for this is that
7367 now the receiver can verify whether the channel message decrypted
7368 correctly and also when private keys are set for the channel the
7369 receiver can decrypt the packet with several keys and check from
7370 the MAC which key decrypted the message correctly.
7372 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7373 lib/silccrypt/silccipher.[ch].
7375 * Added silc_hash_len to return the digest length into the
7376 lib/silcrypt/silchash.[ch].
7378 * Rewrote parts of Silc Channel Payload interface in the
7379 lib/silccore/silcchannel.[ch]. The encode function now also
7380 encrypts the packet and parse function decrypts it.
7382 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7384 * Fixed a minor formatting bug in the SKE's key material processing.
7385 It actually might have processed the keys wrong way resulting
7388 * Redefined the mandatory HMAC algorithms and added new algorithms.
7389 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7390 and hmac-md5 truncated to 96 bits. The mandatory is now
7391 hmac-sha1-96. Rest are optional (including the one that used
7392 to be mandatory). Rationale for this is that the truncated HMAC
7393 length is sufficient from security point of view and can actually
7394 make the attack against the HMAC harder. Also, the truncated
7395 HMAC causes less overhead to the packets. See the RFC2104 for
7398 * Added new [hmac] configuration section. The SKE used to use
7399 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7400 is of course wrong. The official names that must be proposed in
7401 the SKE are the ones defined in the protocol specification
7402 (hmac-sha1-96 for example). The user can configure any hmac
7403 using any hash function configured in the [hash] section. At
7404 least, the mandatory must be configured.
7406 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7408 * Added HMAC list to the SKE proposal list. It has now both
7409 hash algorithm list and HMAC list. This makes the protocol
7410 incompatible with previous versions. The SKE now seems to work
7411 the way it is supposed to work, for the first time actually.
7413 * Defined plain Hash algorithms to the protocol specification.
7416 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7418 * Implemented support for key agreement packets into the server.
7419 Added functions silc_server_key_agreement and
7420 silc_server_send_key_agreement. Other than these functions,
7421 server has nothing to do with this packet.
7423 * Added support for private message key packets into the server.
7424 Added functions silc_server_private_message_key and
7425 silc_server_send_private_message_key.
7429 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7430 called in the protocol's final callback instead in the END
7431 protocol state. This makes a little more sense and in the same
7432 time in client we can use the same protocol routines for normal
7433 key exchange and to key agreement packet handling as well.
7435 * Added to both client's and server's KE protocol context the
7436 SilcSKEKeyMaterial pointer to save the key material. We will
7437 bring the key material to the protocol's final callback by doing
7438 this. The final callback must free the key material.
7440 * Added SKE's packet_send callback into client's KE protocol
7441 context so that the caller can choose what packet sending function
7442 is used. This way we can use different packet sending when
7443 doing normal SKE when doing key agreement packet handling (in
7444 the key agreement packet handling we do not want to encrypt
7447 * Implemented the responder side of the key agreement routines
7448 in the client. The client can now bind to specified port and
7449 accept incoming key negotiation. The key material is passed
7450 to the application after the protocol is over.
7452 * Implemented the processing of incoming Key Agreement packet
7453 in the client. Added function silc_client_key_agreement to
7456 * Implemented the intiator side of the key agreement routines
7457 in the client. The client can now initiate key agreement with
7458 another remote client. The key material is passed to the
7459 application after the protocol is over.
7461 * Created client_keyagr.c to include all the key agreement
7464 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7465 SILC_TASK_CALLBACK except that it is not static.
7467 * Created client_notify.c and moved the Notify packet handling
7468 from the client.[ch] into that file.
7470 * Created client_prvmsg.c and moved all private message and
7471 private message key routines from the client.[ch] into that file.
7473 * Create client_channel.c and moved all channel message and
7474 channel private key routines from the client.[ch] into that file.
7476 * Changed silc_client_get_client_by_id_resolve to resolve with
7477 WHOIS command instead of IDENTIFY command, in the file
7478 lib/silclient/idlist.c.
7480 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7482 * Implemented the SKE's responder side to the Client library.
7484 * When FAILURE is received to the protocol do not trust it
7485 blindly. Register a timeout to wait whether the remote closes
7486 the connection as it should do it, only after that process the
7487 actual failure. This was changed to both client and server.
7489 * Added client_internal.h to include some of the structures
7490 there instead of client.h in lib/silcclient/.
7492 * Added function silc_task_unregister_by_callback to unregister
7493 timeouts by the callback function.
7495 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7497 * Some "Incomplete WHOIS info" errors has been appearing on the
7498 log files. Took away the entry->userinfo check from WHOIS
7499 reply sending. The entry->userinfo is now " " if client did not
7500 provide one. I thought this was fixed earlier but something
7501 is wrong still. Let's see if the error still appears.
7503 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7505 * Fixed a minor bug in the login when the channel key is
7506 re-generated in the server. It used to generate the key in
7507 wrong order and thus caused problems in the channel traffic.
7509 * Fixed a minor bug in channel key distsribution after
7510 KICK command. The key was not sent to the router even though
7513 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7515 * Added silc_ske_process_key_material_data as generic routine
7516 to process any key material as the SILC protocol dictates. The
7517 function is used by the actual SKE library but can be used by
7518 applications as well. This relates to the private message keys
7519 and the channel private keys since they must be processed the
7520 same way the normal SILC session keys. The protocol dictates
7521 this. Affected files: lib/silcske/silcske.[ch].
7523 Added also silc_ske_free_key_material to free the
7524 SilcSKEKeyMaterial structure.
7526 * Defined silc_cipher_set_key function to set the key for
7527 cipher without using the object's method function. The affected
7528 files: lib/silccrypt/silccipher.[ch].
7530 * Implemented silc silc_client_add_private_message_key,
7531 silc_client_add_private_message_key_ske,
7532 silc_client_del_private_message_key,
7533 silc_client_list_private_message_keys and
7534 silc_client_free_private_message_keys functions in the
7537 Added functions silc_client_send_private_message_key to send
7538 the Private Message Key payload and silc_client_private_message_key
7539 to handle incoming Private Message Key payload.
7541 * Added Cipher field to the Private Message Key payload to set
7542 the cipher to be used. If ignored, the default cipher defined
7543 in the SILC protocol (aes-256-cbc) is used.
7545 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7547 * Removed lib/silcclient/ops.h file.
7549 Redefined parts of the SILC Client Library API. Created new
7550 file silcapi.h that deprecates the ops.h file and defines the
7551 published Client Library API. Defined also private message key
7552 API and channel private key API into the file.
7554 This is the file that the application must include from the
7555 SILC Client Library. Other files need not be included by
7556 the application anymore.
7558 * Added new key_agreement client operation callback and also
7559 defined the Key Agreement library API for the application.
7561 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7563 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7564 is used by clients to request key negotiation between another
7565 client in the SILC network. If the negotiation is started it
7566 is performed using the SKE protocol. The result of the
7567 negotiation, the secret key material, can be used for example
7568 as private message key.
7570 Implemented the Key Agreement payload into the files
7571 lib/silccore/silauth.[ch].
7573 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7575 * Redefined ciphers for the SILC protocol. Added some new ciphers
7576 and defined the key lengths for the algorithms. Changed the
7577 code accordingly. The default key length is now 256 bits.
7579 * Fixed SKE key distribution function silc_ske_process_key_material
7580 when the key length is more than 128 bits. The default key
7581 length in SILC is now 256 bits.
7583 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7584 to indicate unsupported algorithm.
7586 * Renamed rijndael.c to aes.c and all functions as well.
7588 * Fixed a long standing channel key setting bug in client library.
7589 Weird that it has never surfaced before.
7591 * Fixed bug in channel deletion. If the entire channel is removed
7592 then it must also delete the references of the channel entry
7593 from the client's channel list as the client's channel entry and
7594 the channel's client entry share same memory.
7596 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7598 * Implemented CONNECT and SHUTDOWN commands in the client.
7600 * Implemented CLOSE command to the client.
7602 * Added the function silc_idlist_find_server_by_name into the
7603 files silcd/idlist.[ch].
7605 Added the function silc_idlist_find_server_by_conn into the
7606 files silcd/idlist.[ch].
7608 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7610 * DIE command was renamed to SHUTDOWN. Updated the both code
7613 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7614 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7616 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7619 * Added function silc_server_create_connection function to create
7620 connection to remote router. My server implementation actually
7621 does not allow router to connect to normal server (it expects
7622 that normal server always initiates the connection to the router)
7623 so the CONNECT command is only good for connecting to another
7626 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7628 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7629 or some other client was kicked from the channel.
7631 Implemented the handling of the notify type to both client
7634 Implemented silc_server_send_notify_kicked to send the KICKED
7635 notify. It is used to send it to the server's primary router.
7637 * Implemented the KICK command into server and client.
7639 * Added `query' argument to the silc_idlist_get_client function
7640 to indicate whether to query the client from server or not if
7643 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7644 to indicate that the client is not channel founder.
7648 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7650 * Removed the rng context from SilcPacketContext structure and
7651 changed that the packet routine uses the Global RNG API.
7653 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7655 * Added support for quit message that client can "leave" on the
7656 channel when it quits the SILC. It is ditributed inside the
7657 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7659 Added silc_server_free_client_data that will take the
7660 signoff message as argument.
7662 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7664 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7666 * Updated parts of the protocol specification to keep it up
7669 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7671 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7672 payloads in one packet.
7674 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7675 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7676 use now the new List flag.
7678 * Also deprecated the following packet types: REPLACE_ID,
7679 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7681 * Added list support for Notify packet in server.
7683 * Added silc_server_send_notify_channel_change to send the
7684 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7685 the silc_server_send_replace_id.
7687 * Added silc_server_send_notify_nick_change to send the
7688 NICK_CHANGE notify type. Deprecates the function
7689 silc_server_send_replace_id.
7691 * Added silc_server_send_notify_join to send the JOIN notify type.
7692 Deprecates the function silc_server_send_new_channel_user.
7694 * Added silc_server_send_notify_leave to send LEAVE notify type.
7695 Deprecates the function silc_server_send_remove_channel_user.
7697 * Added silc_server_send_notify_cmode and
7698 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7699 types. Deprecates the silc_server_send_set_mode function.
7701 * Added SERVER_SIGNOFF notify type to indicate that server has
7702 quit. This means that all clients on the channel from that
7703 server will drop. This can be also used when netsplit happens.
7705 Deprecated REMOVE_ID packet type since it is not needed anymore
7708 Added silc_server_send_notify_server_signoff to send the
7709 SERVER_SIGNOFF notify type. Deprecates the function
7710 silc_server_send_remove_id.
7712 Added also silc_server_send_notify_signoff to send the
7713 SIGNOFF notify type.
7715 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7716 SILC protocol from this day on. Changed the protocol
7717 specification as well.
7719 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7720 notify type. It is used between routers to notify about
7721 topic changes on a channel.
7723 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7726 * Partly updated the protocol specification to comply with the
7727 changes now made. It is still though a bit outdated.
7729 * The JOIN notify type now takes one extra argument <Channel ID>.
7730 The packet used to be destined to the channel but now the
7731 JOIN type may be sent as list thus it is impossible to
7732 destine it to any specific channel. By adding this argument
7733 it is again possible.
7735 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7737 * Added CREDITS file. The CHANGES and CREDITS file will appear
7738 in the distribution as well.
7740 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7742 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7743 types in the server's silcd/packet_receive.c.
7745 * Implemented CMODE and CUMODE to work in router environment.
7747 * Fixed minor encoding and decoding buglet from the
7748 lib/silccore/silcmode.c.
7750 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7753 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7755 * Changed all SilcConfigServer* and silc_config_server* to
7756 SilcServerConfig* and silc_server_config*, respectively.
7759 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7761 * Associated the ID (client or server ID) to the Authentication
7762 Payload to avoid any possibility of forging. Updated the
7763 protocol specification and the code accordingly.
7765 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7767 * The RSA key length is now save to the RsaKey context in the
7768 key generation process in lib/silccrypt/rsa.c. The key length
7769 is now used to figure out the maximum size of the block allowed
7770 to be encrypted/signed.
7772 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7773 is equivalent to the silc_mp_mp2bin but does not allocate any
7776 * Changed silc_mp_mp2bin API to take length argument. If it is
7777 non-zero then the buffer is allocated that large. If zero, then
7778 the size is approximated using silc_mp_sizeinbase, which however
7781 * Created Global RNG API which is global RNG that application can
7782 initialize. After initializing, any routine anywhere in the
7783 code (including library) can use RNG without allocating a new
7784 RNG object. This was done to allow this sort of use of the
7785 RNG in code that has no chance to allocate RNG object. All
7786 applications currently allocate this and many routines in the
7787 library use this. Affected file lib/silccrypt/silcrng.[ch].
7789 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7790 it to use the Global RNG API.
7792 * Defined Authentication Payload into protocol specification that
7793 is used during SILC session to authenticate entities. It is
7794 used for example by client to authenticate itself to the server
7795 to obtain server operator privileges.
7797 Implemented this payload into the lib/silccore/silcauth.[ch].
7798 Implemented also routines for public key based authentication
7799 as the new protocol specification dictates.
7801 Moved definitions of different authentication methods from
7802 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7804 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7805 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7806 silc_pkcs_verify_with_hash functions into the file
7807 lib/silccrypt/silcpkcs.[ch].
7809 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7811 * The client entry's userinfo pointer must be always valid.
7812 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7813 will fail since it requires the userinfo. Now, the userinfo
7814 is allocated as "" if actual userinfo does not exist. Actually,
7815 it must exist and it is totally Ok to drop client connections
7816 that does not announce the userinfo. However, we will make
7817 this workaround for now.
7819 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7820 to return the remote port by socket.
7822 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7824 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7825 SILC_SERVER_PENDING_EXEC and added an new macro
7826 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7827 data or when error occurs while processing the pending command.
7829 Added new argument `destructor' into silc_server_command_pending
7830 and to the SilcServerCommandPending object. This destructor is
7831 now called after calling the pending callback or if error occurs
7832 immediately. If error occurs the actual pending callback won't
7833 be called at all - only the destructor. The destructor may be
7834 NULL if destructor is not needed.
7836 All this applies for client library code as well. Similar
7837 changes were made there as well for the pending commands.
7839 In the client, the application must now allocate the
7840 SilcClientCommandContext with the silc_client_command_alloc
7843 * Added reference counter to the SilcServerCommandContext. Added
7844 function silc_server_command_alloc and silc_server_command_dup
7847 Same type of functions added to the client library for the same
7850 * Removed the cmd_ident from IDListData away since it is now
7851 global for all connections. It is the command identifier used
7852 in command sending and with pending commands. The affected file
7855 * Added reference counter to the SilcSocketConnection objecet to
7856 indicate the usage count of the object. The object won't be
7857 freed untill the reference counter hits zero. Currently only
7858 server uses this, and client ignores it. The client must be
7859 set to use this too later. The affected files are
7860 lib/silccore/silcsockconn.[ch]. Added also the function
7861 silc_socket_dup to increase the reference counter.
7863 This was mainly added because it is possible that the socket
7864 is removed underneath of pending command or other async
7865 operation. Now it won't be free'd and proper DISCONNECTING
7866 flags, etc. can be set to avoid sending data to connection that
7867 is not valid anymore.
7869 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7870 the connection. After that it sets SILC_SET_DISCONNECTED.
7871 It is, however, possible that the socket data is not still freed.
7872 The silc_server_packet_process now checks that data is not
7873 read or written to connection that is DISCONNECTED. The socket
7874 get's freed when the reference counter hits zero.
7876 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7878 * Changed the client operation API: channel_message operation's
7879 `sender' is now the client entry of the sender, not the nickname
7880 and the `channel' is the channel entry, not the channel name.
7882 In the private_message operation the `sender' is now also the
7883 client entry of the sender not the nickname.
7885 Affected file is lib/silcclient/ops.h and all applications
7886 using the client operations.
7888 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7890 * Moved the calling of ops->connect() from connect_to_server_final
7891 into receive_new_id functin since that is the point when the
7892 client is actually allowed to send traffic to network. The
7893 affected file is lib/silcclient/client.c.
7895 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7897 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7898 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7899 (if needs broadcasting) instead of broadcasting the packets one
7900 by one which would make a burst in the network traffic.
7902 * Added `broadcast' argument to the functions in silcd/server.[ch]
7903 silc_server_create_new_channel[_with_id] to indicate whether
7904 to send New Channel packet to primary router.
7906 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7908 * Added new function into the silcd/server.[ch] files:
7909 silc_server_create_new_channel_with_id to create new channel with
7910 already existing Channel ID.
7912 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7913 lib/silccore/silcpacket.h. This packet is used t send list of
7914 Set Mode payloads inside one packet. Server uses this to set
7915 the modes for the channels and clients on those channels, that it
7916 announced to the router when it connected to it. The protocol
7917 specification has been updated accordingly.
7919 * The silc_server_new_channel did not handle the packet coming
7920 from normal server as it normally does not send that. However,
7921 when it announces its channels it does send it. Implemented
7922 the support for that.
7924 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7925 into the file lib/silccore/id.h.
7927 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7929 * Fixed memory leaks in the functions silc_idlist_del_client,
7930 silc_idlist_del_channel and silc_idlist_del_server in the file
7931 silcd/idlist.c. All of those leaked like a sieve.
7933 * Fixed some small memory leaks in the client's function
7934 silc_client_notify_by_server.
7936 * Added functions into silcd/server.c: silc_server_announce_clients,
7937 silc_server_announce_channels and silc_server_announce_server.
7938 These functions are used by normal and router server to announce
7939 to its primary router about clients, channels and servers (when
7940 router) that we own. This is done after we've connected to the
7943 These functions effectively implements the following packet types:
7944 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7945 and SILC_PACKET_NEW_ID_LIST.
7947 * Added new functions into the silcd/packet_receive.[ch]:
7948 silc_server_new_id_list, silc_server_new_channel_list and
7949 silc_server_new_channel_user_list to handle the incoming
7950 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7952 * Added support of changing Channel ID in the function
7953 silc_server_replace_id. If the server that announces a channel
7954 to the router already exists in the router (with same name but
7955 with different Channel ID), router is responsible to send
7956 Replace ID packet to the server and force the server to change
7957 the Channel ID to the one router has.
7959 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7960 client that the Channel ID has been changed by the router. The
7961 normal server sends this to the client. Client must start using
7962 the new Channel ID as the channel's ID.
7964 Implemented handling of this new type into lib/silcclient/client.c
7965 into the function silc_client_notify_by_server.
7967 * Added new function silc_idlist_replace_channel_id into the files
7968 silcd/idlist.[ch] to replace the Channel ID.
7970 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7972 * Call silc_server_command_identify_check always when processing
7973 the IDENTIFY command in silcd/command.c
7975 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7977 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7978 send keepalive packets. The packet can be sent by clients,
7979 servers and routers.
7981 Added function silc_socket_set_heartbeat into the file
7982 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7983 If not set, the heartbeat is not performed. The actual
7984 heartbeat is implemented in the low level socket connection
7985 library. However, application is responsible of actually
7988 Added silc_server_send_heartbeat to send the actual heartbeat
7989 packet into silcd/packet_send.[ch]. Server now performs
7990 keepalive with all connections.
7992 * Added silc_task_get_first function into lib/silcutil/silctask.c
7993 to return the timeout task with shortest timeout. There was a bug
7994 in task unregistration that caused problems. TODO has been
7995 updated to include that task system must be rewritten.
7997 * The client library will now resolve the client information when
7998 receiving JOIN notify from server for client that we know but
7999 have incomplete information.
8001 * Rewrote parts of silc_server_remove_from_channels and
8002 silc_server_remove_from_one_channel as they did not remove the
8003 channel in some circumstances even though they should've.
8005 * Encryption problem encountered in server:
8007 The LEAVE command used to send the Channel Key packet to the
8008 router immediately after generating it. However, the code
8009 had earlier sent Remove Channel user packet but not immediately,
8010 ie. it was put to queue. The order of packets in the router
8011 was that Channel Key packet was first and Remove Channel User
8012 packet was second, even though they were encrypted in the
8013 reverse order. For this reason, MAC check failed. Now, this
8014 is fixed by not sending the Channel Key packet immediately but
8015 putting it to queue. However, this is more fundamental problem:
8016 packets that are in queue should actually not be encrypted
8017 because packets that are sent immediately gets encrypted
8018 actually with wrong IV (and thus MAC check fails). So, packets
8019 that are in queue should be encrypted when they are sent to
8020 the wire and not when they put to the queue.
8022 However, the problem is that the current system has not been
8023 designed to work that way. Instead, the packet is encrypted
8024 as soon as possible and left to the queue. The queue is then
8025 just purged into wire. There won't be any fixes for this
8026 any time soon. So, the current semantic for packet sending
8029 o If you send packet to remote host and do not force the send
8030 (the packet will be in queue) then all subsequent packets to the
8031 same remote host must also be put to the queue. Only after the
8032 queue has been purged is it safe again to force the packet
8035 o If you send all packets immediately then it safe to send
8036 any of subsequent packets through the queue, however, after
8037 the first packet is put to queue then any subsequent packets
8038 must also be put to the queue.
8040 Follow these rules and everything works fine.
8042 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8044 * Added new function silc_server_remove_clients_by_server to
8045 remove all client entries from ID list when the server connection
8046 is lost. In this case it is also important to invalidate all
8047 client entires as they hold the invalid server entry. This
8048 fixes fatal bug when server has lost connection and will reconnect
8051 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8053 * Made some sanity checks to silc_server_daemonise like to check
8054 whether the requested user and group actually exists.
8056 * Added sanity check to SKE's silc_ske_responder_finish to check
8057 that the public and private key actually is valid.
8059 * Invalidate the client's nickname when receiving Replace ID
8060 packet and the Client ID is being replaced. This means that the
8061 server will query the nickname if someone needs it (client)
8064 * Sort the ID Cache in client library when the ID Cache data
8065 has changed (needs sorting).
8067 * Do not allow for SILC client to create several connections to
8068 several servers. The client does not support windows right now
8069 and generating multiple connections causes weird behaviour.
8071 Irssi-silc client does support windows and can handle several
8072 connections without problems, see: www.irssi.org and SILC plugin.
8074 * Fixed some places where client was added to the IDList. The
8075 rule of thumb is following (in order to get everything right):
8076 If the client is directly connected local client then the
8077 `connection' argument must be set and `router' argument must be
8078 NULL to silc_idlist_add_client function. If the client is not
8079 directly connected client then the `router' argument must
8080 bet set and the `connection' argument must be NULL to the
8081 silc_idlist_add_client function.
8083 * The funtion silc_server_packet_send_local_channel actually did
8084 not check whether the client was locally connected or not. It
8085 does that now. Fixed a bug related to LEAVE command.
8087 * Fixed Remove Channel User payload parsing bug in server's
8088 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
8090 * The server's silc_server_save_channel_key now checks also the
8091 global ID list for the channel as it might not be in the local
8092 list. Fixed a bug related to LEAVE command.
8094 * Is this the end of the [<unknown>] buglet that has been lurking
8095 around for a long time? A little for loop fix in server's
8096 silc_server_command_whois_parse that is used by both IDENTIFY
8097 and WHOIS command. At least, this was a clear bug and a cause
8098 of one type of [<unknown>] buglet.
8100 * WHOIS and IDENTIFY commands call the function
8101 silc_server_command_[whois/identify]_check function even if
8102 we are not router server.
8104 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8106 * Added --with-gmp configuration option. If set the GMP
8107 is always compiled in the SILC source tree. If not set then
8108 it is checked whether the system has the GMP3 installed. If
8109 it has then the GMP won't be compiled (the system's headers
8110 and library is used), if it doesn't have it then the GMP is
8111 compiled in the SILC source tree.
8113 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8115 * Changed RSA private exponent generation to what PKCS #1
8116 suggests. We try to find the smallest possible d by doing
8117 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
8118 not security fix but optimization.
8120 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8122 * Added new config entry [Identity] to fork the server and run
8123 it as specific user and group. A patch from Bostik.
8125 * Imported Dotconf configuration library into lib/dotconf.
8126 This will be used to create the SILC configuration files later.
8127 It will appear in the distsribution after this commit.
8129 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8131 * A big code auditing weekend happening. Auditing code for
8132 obvious mistakes, bugs and errors. Also, removing any code
8135 Removed files for being obsolete:
8137 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
8138 inline in the file lib/silcutil/silcbuffer.h)
8140 o lib/silcutil/silcbufutil.c (the header has inline versions)
8142 Changed code to fix possible error conditions:
8144 o The buffer formatting routines now check that the destination
8145 buffer really has enough space to add the data. This applies for
8146 both buffer formatting and unformatting
8147 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
8148 unformatting was changed to accomodate following rules:
8149 XXX_*STRING_ALLOC will allocate space for the data into the pointer
8150 sent to the function while XXX_*STRING will not allocate or copy
8151 the data into the buffer. Instead it sets the pointer from the
8152 buffer into the pointer sent as argument (XXX_*STRING used to
8153 require that the pointer must be allocated already). This change
8154 makes this whole thing a bit more consistent and more optimized
8155 (note that the data returned in the unformatting with XXX_*STRING
8156 must not be freed now). The routines return now -1 on error.
8158 o Tried to find all code that use buffer_format and buffer_unformat
8159 and added return value checking to prevent formatting and
8160 especially unformatting errors and possible subsequent fatal
8163 o Changed ske->x and ske->KEY to mallocated pointers in
8164 lib/silcske/silcske.h. Fixed possible data and memory leak.
8166 o Added return value checking to all *_parse* functions. Fixed
8167 many memory leaks as well.
8169 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
8170 so that buffer overflows would not happen. All code now also
8171 checks the return value as it can fail.
8173 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8175 * Added reconnection support to server if the normal server looses
8176 its connection to the router (for example if router is rebooted).
8177 The server performs normal reconnection strategy implemented
8178 to the server. Affected file silcd/server.c.
8180 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8182 * Added new packet type SILC_PACKET_SET_MODE that is used to
8183 distribute the information about changed modes (for clients,
8184 channels and clients channel modes) to all routers in the
8185 network. Updated the protocol specification accordingly.
8187 Added functions into silcd/packet_send.c and
8188 silcd/packet_receive.c: silc_server_send_set_mode,
8189 silc_server_set_mode.
8191 Added new files silcmode.[ch] into lib/silccore that implements
8192 the encoding and decoding of Set Mode Payload. Added new type
8193 SilcSetModePayload. Moved the definitions of different modes
8194 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
8196 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8198 * Oops, a little mistake in server's connection authentication
8199 protocol. The protocol is not ended with FAILURE but with
8200 SUCCESS if the authentication is Ok. :) Affected file is
8203 * Implemented NICK_CHANGE notify handling in server in the file
8204 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
8205 the local clients on the channel. After the changing nickname
8206 in router environment snhould work and the [<unknown>] nickname
8207 should appear no more.
8209 The silc_server_replace_id function that receives the Replace ID
8210 payload now sends the NICK_CHANGE notify type also in the file
8211 silcd/packet_receive.c
8213 * Changed WHOIS and IDENTIFY command to support the maximum amount
8214 of arguments defined in protocol specs (3328 arguments). This
8215 fixed a bug that caused problems when there were more than three
8218 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8220 * Added extra parameter, command identifier, to the
8221 silc_client_send_command so that explicit command identifier
8224 Changed that ID list routines uses specific command identifier
8225 when sending WHOIS/IDENTIFY requests to the server so that they
8226 can be identified when the reply comes back.
8228 Affected files lib/silcclient/command.[ch],
8229 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
8231 * Added `sender' argument to silc_server_packet_send_to_channel
8232 to indicaet the sender who originally sent the packet to us
8233 that we are now re-sending. Ignored if NULL. Affected file
8234 silcd/packet_send.[ch].
8236 * Added some server statistics support in silcd/server_internal.h
8237 SilcServerStatistics structure and around the server code. Also
8238 send some nice statistics information when client is connecting
8241 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8243 * Fixed channel ID decoding in server's JOIN command reply in
8244 silcd/command_reply.c
8246 * Fixed braodcasting of replace ID payload to not to send it if
8247 we are standalone server in silcd/packet_receive.c.
8249 * Fixed all channel message sending routines to not to send
8250 packets to clients that has router set, since they are routed
8251 separately in the same function earlier. Affects file
8252 silcd/packet_send.c and all channel packet sending functions.
8254 * In USERS reply, res_argv[i] are not allocated, the table
8255 is allocated. Thus changed that free the table, not its
8258 * In server's whois_check and identify_check if the client is
8259 locally connected do not send any WHOIS commands - they are not
8262 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8264 * Fixed some minor bugs in client when sending WHOIS command. The
8265 arguments was in wrong order.
8267 * Removed statis function add_to_channel from server in
8268 silcd/command.c that was previously used with the joining but
8271 * Tested USERS command in router environment successfully with two
8272 routers, two servers and two clients.
8274 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8276 * Reorganized the USERS command and command reply in client library
8277 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
8278 When the command is given by user we register a pending command
8279 callback that will reprocess the command after the reply has been
8280 received from the server. When reprocessing the packet we then
8281 display the information. Thus, the USERS information is displayed
8282 now in the command callback instead of in the command reply
8283 callback. The processing of the command is same as previously
8284 when server has sent the command reply in the JOINing process.
8286 * Added to USERS command in silcd/command_reply.c to join the client,
8287 we didn't use to know about, to the channel after we've created
8288 a client entry for it. Also, for clienet we did know already still
8289 check whether it is on the channel or not and add it if not.
8291 * Removed silc_server_command_join_notify as the function and its
8294 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8296 * Changed the client's pending command handling to the same as the
8297 server's pending command handling. It is also now possible to
8298 execute command reply functions from other command reply
8299 function as the function callbacks for commands and command
8300 replies are one and same. The pending commands are not static
8301 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8302 in client connection context. Thus, pending commands are server
8303 connection specific as it is convenient.
8305 Changed the function silc_client_command_pending and
8306 silc_client_command_pending_del and added new function
8307 silc_client_command_pending_check. Removed the
8308 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8311 * Added cmd_ident, current command identifier, to the client
8312 connection context in lib/silcclient/client.h to keep track on
8313 command identifiers used in command sending. Client's command reply
8314 function handling now supports the mandatory command identifiers.
8316 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8317 funtions in client to fully support pending command callbacks.
8319 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8320 as one of the arguments to the application in the command reply
8323 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8324 before first releasing SILC but came back. Now it is removed again
8325 and should come back nomore. The FORWARDED flag was used only
8326 by the JOINing procedure by forwarding the command packet to router.
8327 Now, the JOINing procedure has been changed to more generic (due
8328 to various router environment issues) and FORWARDED is not needed
8329 anymore for anything. The protocol specification is yet to be
8332 Now, removed silc_server_packet_forward from server and the flag
8333 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8335 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8337 * Renamed NAMES command to USERS command. The NAMES was named that
8338 due to historical reasons. Now it is renamed. Also, rewrote
8339 parts of the USERS command. The nickname list is not sent anymore
8340 by the server. Only Client ID and mode lists are sent in the USERS
8341 command. Changed this also to the protocol specification.
8343 The client now resolves the names and stuff after it receives
8344 the USERS list from the server when joining to the channel.
8346 * WHOIS and IDENTIFY commands has been changed to support multiple
8347 Client ID's per command. One can now search for multiple users
8348 in the network by sending only one WHOIS or IDENTIFY command.
8349 Changed the code and the protocol specifications.
8351 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8352 uses silc_server_command_whois_parse to parse the request. */
8354 * If normal server, do not parse the WHOIS and IDENTIFY requests
8355 before sending it to the router. Saves some time.
8357 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8359 * Fixed JOIN command on client library. Wrong number of arguments
8360 used to crash the client.
8362 * Added silc_server_channel_has_global function to check whether
8363 channel has global users or not.
8365 * Added silc_server_channel_has_local function to check whether channel
8366 has locally connected clients on the channel.
8368 * The silc_server_remove_from_one_channel now checks whether the
8369 channel has global users or not after given client was removed from
8370 the channel. It also checks whether the channel has local clients
8371 on the channel anymore. If it does not have then the channel entry
8372 is removed as it is not needed anymore.
8374 * The silc_server_notify now checks on JOIN notify whether the joining
8375 client is one of locally connected or global. If it is global then
8376 the channel has now global users on the channel and that is marked
8377 to the channel entry. Also, it now saves the global client to
8378 global list who is joining and JOINs it to the channel. This is
8379 for normal server, that is.
8381 Changed silc_server_send_notify_on_channel,
8382 silc_server_packet_relay_to_channel and
8383 silc_server_packet_send_to_channel check if we are normal server
8384 and client has router set (ie. global client) do not send the
8385 message to that client, as it is already routed to our router.
8387 * Implemented LEAVE notify type handling in silc_server_notify
8390 * Tested LEAVE command in router environment successfully. Tested
8391 with two routers, two servers and two clients.
8395 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8397 * Implemented SIGNOFF notify type handling in silc_server_notify
8400 * silc_server_remove_id now removes the client entry from all channels
8401 it has joined and thusly sends SIGNOFF notify type.
8403 * Rewrote the NAMES list generation in server by removing two excess
8404 loops. The lists are created now inside one loop.
8406 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8408 * silc_server_remove_channel_user checks now also global list
8409 for channel and client.
8411 * silc_server_new_channel_user checks now both local and global
8412 list for channel and client. Fixed a bug in client id decoding.
8413 Used to decode wrong buffer.
8415 * silc_server_channel_message checks now both local and global
8416 list for channel entry.
8418 * Tested channel joining (hence JOIN) in router environment
8419 successfully. Tested with two routers, two servers and two
8422 * Tested channel message sending in router environment successfully.
8424 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8426 * Added silc_server_save_channel_key into server.[ch] to save the
8427 received channel key in Channel Key payload processing. It is
8428 also used in JOIN command reply handling.
8430 Equivalent function silc_client_save_channel_key added into
8431 client.[ch] into client library.
8433 * Changed JOIN command reply to send information whether the channel
8434 was created or not (is existing already) and the channel key
8435 payload. Changed protocol specs accordingly.
8437 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8438 the request was sent by ID and not by nickname. Crashed on
8441 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8443 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8444 now correctly save the received data.
8446 * silc_server_free_sock_user_data now notifies routers in the
8447 network about entities leaving the network.
8449 At the same time implemented functions silc_server_remove_id
8450 and silc_server_send_remove_id to receive and send REMOVE_ID
8451 packets. The packet is used to notify routers in the network
8452 about leaving entities. The ID removed will become invalid in
8455 * Added function silc_idlist_del_server into server. Removes and
8456 free's server entry from ID list.
8458 * silc_server_private_message function now checks, if we are router,
8459 that the destination ID really is valid ID, naturally.
8461 * In router when NEW_ID packet is received (for new client) the
8462 hash of the Client ID is saved in the ID Cache but the
8463 client->nickname is set to NULL, instead of putting the hash
8466 IDENTIFY command now also checks that client->nickname must be
8467 valid. If it is not if will request the data from the server who
8468 owns the client. Added new function
8469 silc_server_command_identify_check.
8471 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8472 to set the command to already allocated Command Payload.
8474 * Tested private message sending in router environment with two
8475 routers, two servers and two clients. Fixed minor bugs and now
8478 * Fixed segfault from client's NAMES command. Used to crash if
8481 * Forwarded packets must not be routed even if it is not destined
8482 to the receiver. Changed server code comply with this.
8484 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8486 * Added `require_reverse_mapping' boolean value to ServerParams
8487 structure. If TRUE (not default) the server will require that
8488 the connecting host has fully qualified domain name.
8490 If the reverse mapping is not required and hostname could not be
8491 found the IP address is used as hostname.
8493 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8495 * Implemented version string checking to both client and server.
8496 The check is incomplete currently due to the abnormal version
8497 strings used in development version of SILC.
8499 * Changed all command functions in server to use the new
8502 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8504 * Changed char *data to unsigned char *data in ID Cache system to
8505 support binary data as ID Cache data. Changed code to support
8506 binary data in lib/silccore/idcache.c.
8508 * Renamed silc_server_packet_relay_command_reply to
8509 silc_server_command_reply as it is normal packet receiving
8510 function. Rewrote the function to accept command replys for
8511 servers and not only for clients.
8513 * Mark remote router always as registered server if we are connecting
8514 to it. Otherwise, commands sent by the router to us are ignored.
8516 * All ID List find routines now returns the ID Cache Entry pointer
8517 as well if requested.
8519 * WHOIS command works now in router environment, tested with two
8520 routers, two servers and two clients.
8522 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8523 in router environment (as it is almost equivalent to WHOIS) but
8524 hasn't been tested thoroughly. Added new functions:
8526 silc_server_command_identify_parse
8527 silc_server_command_identify_send_reply
8528 silc_server_command_identify_from_client
8529 silc_server_command_identify_from_server
8531 * Disabled route cache adding because adding two different ID's with
8532 same IP replaces the old cache entry thus giving wrong route.
8533 The entry->router->connection is always the fastest route anyway
8534 so route cache may not be needed. Of course, new routes maybe
8535 established after receiving the ID when the entry->router->connection
8536 might not be anymore the most optimal.
8538 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8540 * Add route cache for received ID for fast routing.
8542 * Added silc_server_packet_route to route received packet on router
8543 that is not destined to us.
8545 * Renamed silc_server_get_route to silc_server_route_get.
8547 * Added id_string and id_string_len fields into SilcServer to
8548 include encoded ServerID for fast comparing without excess
8549 encoding of the ID's.
8551 * Cleaned up WHOIS command on server side. Added following static
8554 silc_server_command_whois_parse
8555 silc_server_command_whois_check
8556 silc_server_command_whois_send_reply
8557 silc_server_command_whois_from_client
8558 silc_server_command_whois_from_server
8560 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8561 arguments in command replies. All command functions should be
8562 updated to use this macro.
8564 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8566 * Minor typo fixes on command reply handling on server.
8568 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8570 * Added silc_server_command_add_to_channel internal routine to add
8571 the client to the channel after router has created the channel and
8572 sent command reply to the server.
8574 * Added generic silc_server_send_command to send any command from
8577 * Use static buffer with ID rendering instead of duplicating data.
8579 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8581 * Fixed a channel user mode bug when joining to a channel server gave
8582 everybody channel founder rights, oops.
8584 * We mark ourselves as the router of the incoming server connection
8585 if we are router ourselves. This way we can check in some packet
8586 sending functions whether it is locally connected server. For
8587 incoming router connections we put NULL.
8589 * For router sending packets locally means now always sending the
8590 packet cell wide; to local clients and local servers. For normal
8591 server sending packet locally means sending it to only local
8594 * Fixed the JOIN command to really work in router environment. If the
8595 channel is created it is always created by the router. Router is
8596 also responsible of making the initial joining to the channel,
8597 sending JOIN notify to the sending server and distributing
8598 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8599 does not exist server doesn't do anything else but forward the
8600 command to the router which performs everything.
8602 * Added silc_server_send_channel_key function to send the Channel Key
8605 * Added silc_server_create_channel_key to create new channel key. The
8606 channel key is now re-generated everytime someone joins or leaves
8607 a channel, as protocol dictates. Note: channel->key_len is the
8610 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8612 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8613 packet_receive.[ch] to separate packet sending and receiving
8614 routines. The server.[ch] now includes everything else including
8615 actual packet processing (writing and reading data) and other
8618 Renamed silc_server_private_message_send_internal to
8619 silc_server_send_private_message. The routine is still though
8620 used only to relay private messages as server does not send
8621 private messages itself.
8623 Renamed silc_server_new_channel to silc_server_create_new_channel
8624 and added new function sicl_server_new_channel that handles the
8625 incoming New Channel packet. Added also new sending function
8626 silc_server_send_new_channel to send New Channel Payload.
8628 * Added new function silc_server_notify to process incoming notify
8629 packet to the server/router. Server may then relay the notify
8630 to clients if needed.
8632 * Added new function silc_server_new_channel_user to process incoming
8633 New Channel User packet. Router will redistribute the packet and
8634 send JOIN notify to its local clients and locally connected servers
8635 if needed. Normal server will send JOIN notify to its local client
8636 on same channel when received this packet. Added also corresponding
8637 sending function silc_server_send_new_channel_user to sent the
8640 * Added boolean route argument to send_notif_to_channel and
8641 packet_send_to_channel functions to attempt to route the packet
8642 if it is TRUE and send only locally if it is FALSE.
8644 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8646 * silc_server_replace_id now broadcasts the received replace ID
8647 packet if it is not broadcast packet already. The router must
8648 broadcast to inform other routers about changed ID.
8650 * Added backpointer to server's router into SilcServer context in
8651 silcd/server_internal.h.
8653 * Fixed silc_server_packet_broadcast to send correct broadcast
8656 * The channel key is now distributed to the local client as soon
8657 as it is received from the router (in router environment) so that
8658 no other packet may be sent for the channel until client has
8661 * silc_server_remove_channel_user now broadcasts the received
8662 Remove Channel User packet if it is not broadcast packet already.
8663 The router must broadcast to inform other routers about removed
8666 * Added users field into SilcPacketContext that is a reference count
8667 of the context. One can increase the reference count by calling
8668 silc_packet_context_dup which is now changed to just increase the
8669 reference count instead of duplicating the data. The reference
8670 count is decresed by calling silc_packet_context_free that will
8671 free the data after the reference count hits zero.
8673 For now on the packet context and everything allocated into it
8674 (including the raw packet from network) must be freed by calling
8675 the new silc_packet_context_free function. Added also new function
8676 silc_packet_context_alloc that must be used now to allocate the
8677 context. This also means that if a routine is asynchronous from
8678 silc_[client/server]_packet_parse_type the packet context must
8679 be duplicated by calling silc_packet_context_dup. Otherwise it
8680 gets free'd after silc_[client/server]_packet_parse_type returns.
8681 Also, one must remember that if packet is duplicated then its
8682 reference count must be decresed by calling the free function as
8683 many times as it was duplicated.
8685 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8686 from both client and server.
8688 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8690 * Made joining to a channel working in router environment.
8692 * Cleaned up JOIN command on server side and create function
8693 silc_server_command_join_channel internal routine to make the
8696 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8698 * Changed silc_command_pending list to SilcDList. Also, added
8699 `ident' field to SilcServerCommandPending structure to identify
8700 the reply and to call correct callback.
8702 Added silc_server_command_pending_check function to replace the
8703 corresnponding macro. The silc_command_pending list is not
8706 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8707 to set identifier to previously allocated Command Payload. It
8708 is used to set identifier for command when resending Command
8711 * Added silc_command_payload_encode_payload to encode Command
8712 Payload buffer from SilcCommandPayload structure.
8714 * Added silc_argument_payload_encode_payload to encode Argument
8715 payload buffer from SilcArgumentPayload structure.
8717 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8719 * Changed WHOIS command to support router connection on server side.
8720 The whois request is always sent to router unless the server is
8721 standalone server. After server has received the reply from the
8722 router will it send the reply to the client.
8724 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8725 broadcast received broadcast packet. The function is used only
8726 by router. The broadcast packet is always sent to the router's
8729 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8730 render given ID to printable string, for log files for example.
8732 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8734 * Made basic router to router connections working. At least they
8735 can now connect to each other but nothing really works the way
8736 they are supposed - yet.
8738 * Added new initiator token to RouterConnection configuration
8739 file in silcd/serverconfig.[ch]. It is used to tell whether we
8740 are the initiator to the remote router or whether we'll expect
8741 the other end to connect.
8743 * Moved registering of listener task to silc_server_init, hence
8744 the server starts listenning as soon as it is run, even if it
8745 does not have connections to other routers. Let's see how well
8748 * Changed default connection retry timeouts for more suitable in
8751 * Removed cipher and such arguments from silc_idlist_add_client
8752 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8753 Added new function silc_idlist_add_data to add the keys and stuff
8756 * Added SilcIDListData structure and added it to SilcClientEntry
8757 and SilcServerEntry as their first field in the structure. This
8758 way we can explicitly cast the ID entries to the SilcIDListData
8759 structure and get common data for the entries. In past, we had
8760 to first check what type of connection it is and then cast it to
8761 correct ID entry type. Now, we can directly cast the opaque
8762 pointer to the SilcIDListData (no matter what ID entry it actually
8763 is) and get the data needed.
8765 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8767 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8768 in some circumstances even if threre were timeout tasks, though not
8769 IO tasks, but tasks anyway. Now fixed.
8771 * Defined SilcServerConnection structure to hold connection specific
8772 stuff about directly connected servers and routers. The definition
8773 is currently in silcd/server_internal.h. I thought about having
8774 a bit more important role fro this struct but for now it is used
8775 only when connecting to other server (or router actually).
8777 * Added connecting retry support in server when connecting to
8778 router(s). The retry feature implement exponential backoff
8779 algorithm. Also, added SilcServerParams structure to hold default
8780 parameters for server. For now, it include these retry settings
8781 and are hard coded. After server is moded to be as Silc Server
8782 Library this structure will be more important.
8784 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8786 * Changed client librarys channel->clients table to SilcList and
8787 changed code accordingly.
8789 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8791 * Changed client's channel table to SilcList and changed code
8792 accordingly. Also changed SilcChannelClientEntry to include back-
8793 pointer to the channel so that client entry can use that structure
8794 as list as well and we have fast cross-reference to the channel.
8795 This change dramatically decreased the complexity of channel
8796 handling with client entry and vice versa (removed one extra
8797 loop when searching for channel entry from many functions).
8799 * Changed server->sim from table to SilcDList and changed code
8802 * NAMES command can now be used from user interface. It will show
8803 the user list on the channel, neatly.
8805 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8806 Code now saves realname of the user if it becomes available.
8808 * Renamed configure.in to configure.in.pre and made ./prepare
8809 script to automatically add correct version string to
8810 configure.in which it creates from configure.in.pre.
8812 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8814 * NAMES command reply now shows users mode with the nickname when
8817 * Moved silc_client_ch[u]mode[_char] functions from
8818 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8819 place sucks, they are utility functions and should be in some
8822 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8824 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8827 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8831 * Added TRQ (efficient deque and list library) into lib/trq. This is
8832 a very good list library that is currently used in the SILC. Defined
8833 SilcList API over the library because I didn't like the API very
8834 much. See lib/trq/silclist.h for the API and examples of how to
8835 use the API. Fixed various places in the code to use the new
8836 SilcList API. The SilcList is meant for lists that has a structure
8837 already defined as a list. It is not suitable to add just some
8838 context to the list (in TRQ, the context is the list actually).
8840 So, I defined SilcDList that can be used for the purpose where
8841 predefined list structure does not exit. This can be used as
8842 such list. Now some context just can be added to the SilcDList.
8843 Currently this list is not used in the SILC just yet, though there
8844 are a lot places where this can replace dynamically allocated
8845 tables and I will fix these places, later, to use SilcDList.
8846 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8847 and use TRQ internally).
8849 Also fixed some annoying warning messages that the original TRQ
8850 code generated. Also minor changes to TRQ's Makefile.in.
8852 * Added support for querying by Client ID to both WHOIS and
8853 IDENTIFY commands into server, as required by the protocol.
8855 * Removed method function pointers from SilcBuffer structure. They
8856 weren't used to anything and just increased the context size for
8857 no good reason. This change also made silc_buffer_alloc and
8858 silc_buffer_free functions inline functions.
8860 * Disabled command flooding detection support until it's fixed so
8861 that it accepts commands in but does not execute them more than once
8864 * Added silc_net_localhost(), to return local hostname, into
8865 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8866 that must be initialized before calling silc_client_init.
8868 * Added new function: silc_server_send_notify_on_channels to send
8869 notify messages to all channels client has joined. It is assured
8870 that the message is sent only once per client.
8872 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8873 lib/silcutil/silcutil.[ch] as silc_format function. The new
8874 function is generic and is used by server as well, not only by
8875 the logging routines.
8877 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8878 the provided version string was not acceptable. Added new function:
8879 silc_ske_check_version into lib/silcske/silcske.h. The function
8880 must be implemented by the application (client or server) and it
8881 does not reside in the SKE library. The function checks the version
8882 string remote end sent.
8884 * Added back pointers (to opaque context and to SilcSocketConnection)
8885 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8887 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8888 duplicate packet context structure.
8890 * Changed `notify' client operation to send same arguments as client
8891 receives from server except for ID's. ID's are mapped to correct
8892 ID entry and that is returned. Also, if channel entry is not sent
8893 by server but the notify is for channel the channel entry is sent
8894 to application (otherwise application doesn't know that it is for
8895 channel (library gets it from packet's Destination ID)).
8897 * Added silc_client_remove_from_channels into client library to
8898 remove a client from all channels it has joined to. Used when
8899 received SIGNOFF notify from server. Added also new function
8900 silc_client_replace_from_channels to replace old ID entry with
8901 new ID entry on all channels. Used when received NICK_CHANGE
8904 * Fixed ID Cache list handling in silc_idlist_get_client in
8905 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8906 to get (or query) client by ID.
8908 * Updated TODO list.
8910 * Added connection authentication status message defined by the
8911 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8912 support for these into the code in client and server side.
8914 * Added generic function silc_client_send_command to send any command
8915 with variable argument list. Application should use this function
8916 to send commands if the command functions provided by the library
8917 does not suite for the application's user interface needs.
8919 * Added new `failure' client operation. Application is notified about
8920 received failure packet if client is executing a protocol. In this
8921 case the protocol's execution has failed.
8923 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8924 is required by the protocol.
8926 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8927 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8930 * Added status flag to SilcSKE object to indicate realtime status
8931 of the SKE protocol.
8933 * Application receives now exactly same command reply arguments as
8934 the library receives from server. However, if ID is received the
8935 corresponding ID entry is returned to the application (eg. Client
8936 ID is mapped to correct SilcClientEntry entry and that is returned).
8937 Changed command_reply client operation due to this change.
8939 * Changed all ID's in commands and in command replys as ID Payloads.
8940 Change affected both client and server side codes.
8942 All ID's sent in SILC network (with execption of ID's in SILC
8943 Packet header) are sent in ID Payload to support variable length
8946 * Server now notifies nick changes and notifies all clients on
8947 the channels about the new nickname (about the new Client ID,
8950 * Implemented CMODE command to change channel modes. Supports all
8951 channel modes defined by the protocol specs except ban and invite
8952 lists. (Also, private channel key mode is supported but support for
8953 setting private channel key in client is missing, thus, this mode
8954 has no effect on client side (except that server requires that the
8955 client uses private channel key and normal channel traffic does not
8958 Also, invite mode works per se, but INVITE command does not work
8959 yet correctly, so you can set channel as invite only channel but
8960 inviting clients to the channel does not work (it is yet to be
8961 thought what's the best way to do it).
8963 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8964 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8965 Implemented CUMODE command to change user's mode on the channel.
8966 Supports all modes defined by the protocol specs.
8968 * Added NAMES command reply to return users modes on the channel.
8970 * Removed unnecessary and slow ciphers from lib/silccrypt.
8972 * Set SO_KEEPALIVE option to connection sockets by default.
8974 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8976 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8977 redefined the Notify Payload into protocol specs.
8979 * Added silc_id_payload_parse_id to get ID directly from raw
8982 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8984 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8985 accept searching by Client ID as well.
8987 * Added support for LEAVE and SIGNOFF notify types in client library.
8989 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8990 to parse ID Payload from raw data.
8992 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8994 * Added flags parameter into silc_ske_assemble_security_properties
8995 function in lib/silcske/silcske.[ch].
8997 * Changed notify client operation to fit better for notify messages
8998 sent by server. The notify payload received from server is now
8999 passed to the application (after parsing it to SilcNotifyPayload).
9000 It is application's responsibility to retrieve the arguments
9001 from the payload and show the message the way it wants. The message
9002 sent by server is implementation specific.
9004 * Changed public keys to comply with the protocol specification.
9005 Old public keys are not supported anymore and are not compatible.
9007 * Removed nickname from Channel Payload as the latest draft removed
9008 it. The client must resolve the nickname from the NAMES command
9009 reply received when it joined the channel.
9011 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
9013 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9015 * Fixed some errors in protocol specification drafts.
9017 * Created lib/silccore/silcnotify.c to implement Notify Payload
9018 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
9019 generic payloads described by protocol specifications. The file
9020 includes implementations for ID Payload and Argument Payload.
9022 * Changed Command Payload implementation to use the new Argument
9023 Payload. Changed command_xxxx_payload to command_payload_xxxx
9024 to comply with SILC coding conventions.
9026 * Added suppport for Argument Payload handling in Notify Payload
9027 implementation as protocol requires it. Added the new support
9028 into server and client lib as well.
9030 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9032 * Added support for multiple nicknames on same channel. [n] is
9033 added locally to the nickname if there are more than one same
9034 nicknames on the channel.
9036 * Server now sends all nicknames that matched WHOIS request.
9037 Client also shows the list received from server.
9039 * Added TOPIC command to client side. User can now set and show
9040 current topic on channel.
9042 * Added MOTD command to client and server. Also, server sends the
9043 motd when client connects to the server.
9045 * Changed version strings to comply ISO 8601.
9047 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9049 * Fixed protocol error handling in client library. It should now
9050 cope even if the SKE fails for some reason.
9052 * Made new protocol specification drafts for submitting to IETF.
9054 * Implemented TOPIC command to server in silcd/command.c.
9056 * Added two new notify types into lib/silccore/silcnotify.h:
9057 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
9058 notify nickname change and topic setting/change on a channel.
9060 * API change of command_reply operation in client library. The
9061 application gets now the status type received from server as well.
9063 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9065 * Removed the function just added to lib/silcutil/silcschedule.[ch].
9067 * Cras fixed and optimized the packet handling even further and
9068 it should work now. Minor change to the prototype of function
9069 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
9071 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9073 * Added new function into lib/silcutil/silcschedule.[ch]:
9074 silc_schedule_with_fd to select() a specified fd. The function
9075 returns after timeout expires or data arrives or goes. The
9076 function is used by packet routines to wait that all data is
9077 received from network.
9079 * Fixed data reading from network in lib/silccore/silcpacket.c.
9080 The code now assures that all data is read from the fd and then
9081 continues packet processing. This was a bug fix since the code
9082 used to drop some data in some circumstances.
9084 * Added new function into lib/silcclient/client.[ch]:
9085 silc_client_start_key_exchange to start key exchange after
9086 connection has been established to server. The code internally
9087 now uses this funtion but its main purpose was to provide it
9088 for applications that perform their own connecting. After
9089 application has created a connection it merely calls this
9090 function to start the key exchange between client and server.
9091 The library takes care of everything else after that.
9093 Updated also lib/silcclient/README to explain the usage of
9096 * Do not send to application information that connection has
9097 been established. Application gets notified it by connect
9100 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9102 * Applied cras's patch to add silc_schedule_one function. The
9103 function runs scheduler once and returns.
9105 * Fixed the scheduler after cras messed it up. The timeout
9106 handling works now as it's supposed to work.
9108 * Added into lib/silccore/ silcnotify.h to include notify
9109 message types support. Changed silc_server_send_notify*
9110 functions, in server.[ch], to support those new notify types.
9111 Added the support for the notify types into client library,
9112 as well. Added new notify client operation into ops.h in
9115 * Changed silc_server_packet_send_to_channel to send normal
9116 packets instead of just channel message packets. The function
9117 is now used to send the notify packets to channels. It is not
9118 used to send channel message packets anymore, as server never
9121 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
9122 va_arg()s as it seems to require it nowadays. I guess, if SILC
9123 is compiled with older va_arg() the new code should work anyway.
9125 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9127 * Splitted core library. Core library (lib/silccore) includes
9128 now only SILC protocol specific core (and common) components.
9129 Created new utility library (lib/silcutil) that includes more
9130 generic purpose stuff. The stuff for util library was taken
9131 from the old core library. This was minor and easy split.
9133 * Created SILC Client Library (lib/silcclient) that includes
9134 implementation of the SILC client without user interface. This
9135 was major move from silc/ directory. The code has been changed
9136 so that it is transparent towards the user interface. The
9137 silc/ directory includes now the same user interface as before
9138 and it uses the new client library. Read lib/silcclient/README.
9139 Basicly, the client library performs everything else related
9140 to SILC except user interface handling. Also, configuration
9141 files are considered to be part of user interface and library
9142 does not handle them.
9144 This change also changed a lot of structures, function naming etc.
9145 Most important change was that SilcClientWindow object was
9146 renamed to SilcClientConnection in the client library. Created
9147 also new file lib/silcclient/ops.h. Also added new files
9148 silc/local_command.[ch] and silc/client_ops.[ch].
9150 All these changes were made to make it easier for user interface
9151 designers to create what ever user interface for the SILC client
9154 It is also expected that the server will be moved to lib
9155 directory as well and SILC Server Library will be created;
9156 sometimes in the future.
9158 * Removed Local commands from lib/silccore/silccommand.h as
9159 they are application specific and new client library does not
9160 handle any of those anymore.
9162 * Several functions moved to lib/silcutil/silcutilc.[ch] from
9163 old client implementation in silc/.
9165 * Added support for callback functions in SILC_LOG_* macros.
9166 Application can now set its own callbacks that will be called
9167 instead of using the default functions that will always print
9168 the debug messages to stderr (or stdout). Also, debugging can
9169 now be disabled by setting silc_debug to FALSE and re-enabled by
9170 setting it to TRUE. Note, that logging will still work even
9171 if debugging is disabled.
9173 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
9174 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
9175 silc_log_reset_debug_callbacks.
9177 * To enable debugging in silc client one must give now -d
9178 option on command line.
9180 * Changed silc_schedule_init to automatically allocate task queues
9181 if they are not allocated before calling it.
9183 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9185 * Added GMP 3.1 into math library.
9187 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9189 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
9190 a channel in SILC network. The packet is used by servers and
9191 routers to notify other routers that user has left a channel.
9192 This little feature was missing until now. Added the feature
9193 to protocol specification as well.
9195 Added functions: silc_server_send_remove_channel_user and
9196 silc_server_remove_channel_user into server.[ch].
9198 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
9199 lib/silccore/silcpacket.h. However, they are not implemented
9202 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9204 * Fixed joining to a channel and sending channel messages
9205 between server and router. The channel message sending should
9206 now work inside a cell.
9208 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9210 * Fixed the private message sending between server and router.
9211 The private message sending should now work inside a cell.
9213 * Added silc_server_replace_id into server.[ch] to replace
9214 existing ID in the SILC network.
9216 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
9217 and silc_idlist_replace_server_id into idlist.[ch] in server.
9219 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9221 * Fixed the server to server connections. Server can again now
9222 connect to router. Router to router connections probably does
9225 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9227 * Added dynamic protocol registering support. Now protocols can
9228 registered and unregistered on the fly. Patch by cras.
9230 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9232 * Added lib/contrib directory to hold routines that some platforms
9233 don't have but are needed by SILC.
9235 * Added getopt.c, getopt1.c and getopt.h from GNU C library
9236 into lin/contrib to provide getopt() and getopt_long() for
9237 those who don't have it.
9239 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9241 * Added AWAY command to client. When away message is set and
9242 client receives a private message packet the client automatically
9243 replies to the sender with the away message.
9245 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
9246 bug seemed to be the cause of recent problems when compiling
9249 * Added version detection support to SKE protocol specification
9250 and added the new changes to the SKE implementation as well.
9251 There were other minor changes in the SKE protocol as well.
9253 Many changes in lib/silcske/silcske.[ch] and in
9254 lib/silcske/payload.[ch].
9256 * Added ^U functionality, clear input line. Patch from cras.
9258 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9260 * Mainly small bugfixes on core library. Fixed some debugging
9261 logging and buffer overflow in silclog.c.
9263 * Updated config.sub and config.guess on the distribution tree.
9265 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9267 * Added command lagging support in server. Client may execute
9268 commands now only once in two seconds.
9270 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9272 * Optimized packet reception. MAC computation and checking is now
9273 also more optimized. A lot previously duplicated code is now
9274 used as generic by both client and server.
9276 * Fixed key pair generation in clientutil.c
9278 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9280 * Added into lib/silccore/silcbufutil.[ch] new function;
9281 silc_buffer_realloc.
9283 * Moved generic packet sending/encryption functions to
9284 lib/silccore/silcpacket.[ch] from client and server. Some
9285 rewriting of the functions.
9287 * Moved all generic packet reception/decryption functions to
9288 lib/silccore/silcpacket.[ch] from client and server. The
9289 packet processing is now much cleaner in both client and server.
9290 These were major changes in both client and server.
9292 * Created many common functions in server to do packet sending.
9293 Previously code were duplicated a lot, this has been removed
9296 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9298 * Rewrote major parts of the ID cache system. Don't know
9299 whether it is better now or not but at least the API is more
9302 * Major rewrite on ID cache stuff on client because of the ID
9303 cache API changes. Added idlist.c to client.
9305 * Also major rewrite on ID cache stuff on server as well.
9306 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9307 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9308 in hand, instead they are all put into the ID cache system now.
9309 All server_idlist_* routines uses ID cache now instead of
9310 traversing its own lists (those lists does not exist anymore).
9311 SilcIDList though still exists. Also, SilcXXXEntry's are
9314 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9316 * Finally made the SKE implementation compliant to the protocol
9317 specification. All mp integers are now binary encoded as
9318 opposed being HEX encoded.
9320 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9323 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9324 functions: silc_[encode/decode]_pem. Also added function
9325 silc_encode_pem_file to PEM encode with newlines ('\n') for
9328 * SILC public keys are now encoded either PEM or binary. Same
9329 option is for private keys as well. By default private keys
9330 are binary encoded and public keys PEM encoded. Silly HEX
9331 encoding were removed.
9333 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9334 function to create fingerprints.
9336 * Fixed a bug in SHA1; does not change the original data anymore.
9338 * Partly implemented INFO command on client and server side.
9339 Fixed CLEAR command. Changes to SERVER command; show current
9340 server(s) when giving command without arguments. Added
9341 VERSION command to client.
9343 * Added check to server that unregistered connections cannot
9344 execute commands (unless it is specificly allowed).
9346 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9348 * Fixed screen refresh.
9350 * Fixed channel joining bug from client. On some circumstances
9351 client tried to join to a channel it had already joined.
9353 * Added public key verification process into client's protocol.c.
9354 The client now verifies the public key from user and saves
9355 it into ~./silc/serverkeys/ directory.
9357 Added into: clientutil.[ch]: silc_client_verify_server_key.
9359 * Changed SKE protocol's silc_ske_initiator_finish function
9360 to accept callback function that verifies the received public
9361 key. Removed old silc_ske_verify_public_key function.
9363 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9365 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9366 silc_pkcs_private_key[_data]_set.
9368 * Made the password and public authentication more cleaner in
9369 server's protocol.c.
9371 * Removed historic and obsolete protocol `channel_auth' from
9372 both client and server.
9374 * Removed wrong way of sending command status messages from
9375 server to client in server's command.c. The old way violated
9376 protocol specification.
9378 Changes to silccore/silccommand.[ch]: removed
9379 silc_command_encode_status_payload -> not needed anymore,
9380 changed silc_command_encode_payload_va to accept extra
9381 argument on variable argument list. The argument type must
9382 now be provided to the function. Also, added new function:
9383 silc_command_encode_reply_payload_va which is same as
9384 normal command_encode_payload_va except command status type
9385 is provided as extra argument.
9387 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9389 * Added ~./silc directory handling. The directory includes the
9390 public and private keys for the client.
9392 Added silc_client_check_silc_dir, silc_client_create_identifier
9393 and silc_client_load_keys.
9395 * Implemented SILC protocol compliant public key. Added public
9396 and private key saving to and loading from files.
9398 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9399 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9400 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9401 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9402 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9404 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9405 silc_pkcs_load_[public/private]_key.
9407 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9409 * Added silc_server_get_route (route.[ch]) to get connection
9410 data for the fastest route for given ID.
9412 * Implemented INVITE command on client and server. The command
9413 were re-defined in the SILC Protocol Specification and the
9414 implementation now complies with the specification.
9416 * Implemented PING command on client and server.
9418 * Implemented NAMES command on client and server. The server side
9419 supports currently only normal server not router server yet.
9420 Some changes to NAMES definition in SILC protocol specification.
9422 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9424 * Implemented LEAVE command on client and server.
9426 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9427 again. This change was made to the protocol as well. Server
9428 should not violate the protocol specification anymore.
9430 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9432 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9433 was tested. SOCKS4 was not but should work anyway.
