79 Fri Oct 11 23:52:17 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
81 * Some strncat -> silc_strncat changes our the core and
84 * Added SILC_SKE_STATUS_SIGNATURE_ERROR and OUT_OF_MEMORY
85 errors. Added better error printing to SKE library.
86 Affected files lib/silcske/silcske.c, silcske_status.h and
89 * Save the PKCS key length even if only private key is set to
90 SilcPKCS. Affected file lib/silccrypt/silcpkcs.[ch] and rsa.c.
92 * Fixed the usage of silc_pkcs_get_key_len since it returns the
93 length in bits not in bytes. Affected files are
94 lib/silcske/silcske.c, lib/silccore/silcauth.c and
97 Wed Oct 9 17:22:57 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
99 * Added silc_attribute_payload_encode_data to directly encode
100 the data into the attributes buffer. Renamed function
101 silc_attribute_payload_parse_list to silc_attribute_payload_parse.
102 Affected files are lib/silccore/silcattrs.[ch].

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

136 silcd/server_query.c.
138 Mon Oct 7 18:25:35 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
140 * Changed the silc_attribute_payload_encode to support list
141 of attributes (function may be called several times to add
142 a new attribute). Removed the silc_attribute_payload_encode_list
143 function. The encoding function now also automatically encodes
144 the data, so the caller does not need to do that. Affected
145 files lib/silccore/silcattrs.[ch].
147 * Added support for replying on behalf of the user to the
148 Requested Attributes in WHOIS command in the server. Affected
149 file silcd/server_query.c.
151 * SILC_NOT_IMPLEMENTED macro use SILC_LOG_INFO now instead of
152 SILC_LOG_DEBUG. Affected file lib/silcutil/silclog.h.
154 Sun Oct 6 16:48:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
156 * Don't swtich to become primary router if we are backup if
157 decryption error has occurred. Affected file silcd/server.c.
159 * Fixed a bug in backup router IP address comparison in
160 silc_server_backup_get.
162 Save now also the port of the server/router and use that
163 in comparison as well. Affected file silcd/server_backup.c.
165 * Normal server now reconnects to backup router automatically
166 if connection is lost to it. Affected file silcd/server.c.
168 Thu Sep 26 13:51:02 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
170 * If packet processing fails (like integrity check fails)
171 the connection is closed now. Affected files are
172 lib/silccore/silcpacket.c and silcd/server.c.
174 Mon Sep 23 10:59:39 CEST 2002 Pekka Riikonen <priikone@silcnet.org>

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

198 * Resumed client packet handling from server put the resumed
199 client on wrong list on router and caused the client not
200 be present on the network anymore. Now fixed to put the
201 client to correct list. Affected file silcd/packet_receive.c.
203 Wed Sep 18 15:13:48 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
205 * Various cleanup in error message output in config parsing code
206 and in server init code. Fixed error log files containing
207 too many newlines ('\n') in some situations. Affected files are
208 silcd/serverconfig.c, silcd/silcd.c, and silcd/server.c.
210 Wed Sep 18 10:51:23 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
212 * Use the reverse lookupped hostname in client internals
213 instead of one user provided us as remote server name.
214 Affected file lib/silcclient/client.c.
216 Mon Sep 16 12:02:54 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
218 * Added 'app_context' to silc_schedule_init. It is an
219 application specific context that is delivered to application
220 in task callback functions. Affected files are
221 lib/silcutil/silcutil.[ch].
223 * The hb_context in SilcSocketConnection is not freed
224 automatically anymore (application must free it). Freeing
225 it automatic is inconsistent. Affected files are
226 lib/silcutil/silcsockconn.[ch].
228 Sun Sep 15 22:16:19 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
230 * Added support for removing explicitly added client connections
231 in rehash and closing the client connections if they were
232 unconfigured in the rehash. Affected file silcd/server.c.
234 * Added support for aborting automatically pending commands
235 that never receives the reply (to avoid memory leaks).
236 Added also silc_server_command_pending_timed to set the
237 specific timeout for pending command. Affected files are
238 silcd/command[_reply].[ch].
240 * Added SILC_STATUS_ERR_TIMEDOUT status. Updated protocol
241 specs and lib/silccore/silcstatus.h.
243 Sun Sep 15 12:25:10 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
245 * Changed the silc_get_time to accept time value as argument
246 or if zero is sent return current local time. Affected
247 file lib/silcutil/silcutil.[ch].
249 * Added STATS command to client library and Irssi SILC client.
250 Patch provided by Ville Räsänen <ville.rasanen@iki.fi>.
252 Wed Sep 11 09:22:00 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
254 * Assure that channel key is set before sending it. May
255 crash server otherwise. Affected file silcd/packet_send.c.
257 Tue Sep 10 09:50:08 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
259 * Assure that endless loop cannot happen with detached client
260 resolving on normal server. Added idlist status
261 SILC_IDLIST_STATUS_RESUME_RES. Affected files are
262 silcd/idlist.h and silcd/packet_receive.c.
264 Mon Sep 9 12:18:18 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
266 * Incoming file transfer request cannot use same session as
267 the sending session. This can happen when sending file to
268 yourself. Crashed the client on quit. Affected file
269 lib/silcclient/client_ftp.c. Bug #24.
271 Sun Sep 8 18:39:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
273 * Implemented the draft-riikonen-precense-attrs draft and
274 the Attribute Payload into the lib/silccore/silcattrs.[ch].
276 Sun Sep 8 13:13:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
278 * Distribute the SERVER_SIGNOFF notify also to local backup
279 routers from the primary router. The backup router may not
280 have the signing of local server directly connected and need
281 to know about the signoff. Affected file silcd/server_util.c.
283 * Use the primary router as the origin of the locally connected
284 server when it is disconnecting from the backup router since
285 that's where it really is coming from. Now the clients from
286 the disconnecting server are removed correctly and "shadow"
287 clients are not left to the backup router. Affected file
290 Sat Sep 7 22:26:50 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
292 * If normal server is standalone and found existing but disabled
293 channel, do not re-create the channel since it creates
294 duplicate same channels. Affected file silcd/server.c.
296 * Added anonymous client connections support to server. New
297 "anonymous" configuration option to ConnectionParams section
298 added. If set to true, the username and hostname information
299 of the client will be scrambled and anonymous user mode is
300 set automatically to the user. Affected files are
301 silcd/serverconfig.[ch], silcd/packet_receive.c and server.c.
303 Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
305 * In JOIN notify handling, mark that the cache entry of the
306 client cannot be expired. Can cause crashes on normal
307 server (asserts client->channels). Affected file is
308 silcd/packet_receive.c.
310 * From now on distribution versions are used as protocol versions
311 instead of by default using the Toolkit base version as protocol
312 version. Affected file prepare.
314 * Do not set the locally resolved hostname for local client
315 entry but take what server sends. This way the real hostname
316 is showed in WHOIS for yourself. Affected file is
317 lib/silcclient/idlist.c and lib/silcclient/client.c.
319 * Resolve local info with IDENTIFY when connecting to server.y
321 Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
323 * Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
324 for implied search (not needed on platforms which has native
325 pthreads library). Use --without-pthreads to disable threads.
326 Affected file is configure.in.pre
328 * Fixed --with-iconv on platforms which need to bypass (broken)
329 native iconv(). Affected file is configure.in.pre
331 Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
333 * Moved -C option parsing in Irssi SILC client at same time
334 as other options. The UI was initialized earlier and caused
335 problems on command line. Bug #16. Affected file is
336 irssi/src/silc/core/silc-core.c.
338 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
340 * Added global variable silc_log_timestamp that tells silclog
341 wether to print or not the timestamp in the logging files.
342 Affected file lib/silcutil/silclog.[ch].
344 * Added silcd configuration option Timestamp in the Logging
345 section. Affected file silcd/serverconfig.[ch],
346 doc/example_silcd.conf.in.
348 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
350 * Fixed fingerprint checking to check for entirely empty
351 fingerprint instead of two first bytes when determining
352 if it is set. Bug #18. Affected file silcd/command.c.
354 * Fixed duplicate PKCS name registering to not allow it.
355 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
357 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
359 * Conditionalize non-gcc compiler optimizations for various
360 platforms, enable those commented out. Cleanups.
361 Affected file lib/silcmath/mpi/configure.in
363 Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>
365 * silc_rng_exec_command() left zombie processes if command
366 didn't generate any output. Affected file
367 lib/silccrypt/silcrng.c
369 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
371 * Rewrote iconv checking, introduce --with-iconv for systems
372 which rely on libiconv. Check if iconv() provided by libc
373 is good enough, otherwise demand libiconv. Affected file
376 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
378 * Search for ldopen() also in libc. This enables SIM support
379 on *BSD systems. Based on patch from Alex Zepeda. Affected
380 file configure.in.pre
382 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
384 * Don't call AM_CONDITIONAL conditonally for SILC_THREADS.
385 This fixes prepare on *BSD systems. Affected file
388 Sun Aug 4 15:55:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
390 * More fixed for not having purge timeout for global clients
391 that are on channel. Affected files silcd/command_reply.c
394 * Fixed the rekey protocol to work with backup router connections.
395 Rekey packets are now allowed on disabled connections as
396 well. Affected files silcd/packet_send.c and server.c.
398 * Do not switch to be as backup router when shutting down and
399 closing the primary connection. Affected file silcd/server.c.
401 * Fixed memory leaks in backup router deleting. Added
402 silc_server_backup_free to free all data during shutdown of
403 server. Affected files silcd/server_backup.[ch].
405 Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
407 * Do not process commands if the sock->user_data is NULL.
408 Affected file silcd/command.c.
410 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
412 * Fixed buffer overflow and security problems (loosing bits
413 in CFB encryption) in SILC RNG. Problems reported by
414 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
416 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
418 * Added yet more checks that client is not expired on global
419 list if it is on channels. Affected file is
420 silcd/command_reply.c.
422 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
424 * Merged c0ffee's MIME signal patch which adds support for
425 sending also MIME messages in Irssi SILC Client, and handling
426 received MIME messages in a signal (and perhaps doing something
427 to non-textual MIME messages).
429 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
431 * Fixed pending command deletion in server and client library
432 to check the whole list instead of breaking after first found.
433 The affected files are silcd/command.[ch] and
434 lib/silcclient/command.[ch].
436 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
438 * Return NO_SUCH_CHANNEL error in USERS for channel that is
439 secret or private, otherwise it's possible to find out
440 whether a secret channel exists or not. Affected file
443 * If CMODE change fails during the mode setting, assure that
444 the old mode mask is set for the channel back. Affected
445 file silcd/command.c.
447 * Fixed passphrase saving on +a channel on normal server
448 after successful JOIN command. Affected file silcd/command.c.
450 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
452 * Remove server/router operator privileges in DETACH command,
453 since it's possible to resume to server where these
454 privileges would not be allowed for the client. Affected
455 file silcd/command.c.
457 * Do not set to wait for backup in rehash of the server.
458 Affected file silcd/server.c.
460 * Do not check listener sockets when counting how many
461 socket connections we have. Affected file is
464 * Do not announce disconnected clients that are remaining
465 in history (for WHOWAS). This is because SIGNOFF notify
466 for these has been sent earlier already. Affected file
469 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
471 * Buffer overflow with CUMODE command's mode->mode character
472 conversion. Reported by Ville Räsänen. Affected file
473 lib/silcutil/silcutil.c.
475 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
477 * Allow heartbeat packets to go disabled connections anyway.
478 Affected files silcd/server.c and silcd/packet_send.c.
480 * Do not broadcast New Channel packets with List flag set
481 in the packet to backup routers. The router must check
482 for the correctness of the packets before sending them.
483 It is possible that router will have enforce Channel ID
484 change and this would cause desync in the backup router.
485 Affected file silcd/packet_receive.c.
487 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
488 are handled in list parsing. They are not list packets
489 anymore. Affected file silcd/packet_receive.c.
491 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
493 * Stop waiting for backup router through the timeout, not
494 directly after backup router has arrived. Affected file
497 * Do not re-create channel keys and send them when removing
498 clients in server shutdown. Affected files are
499 silcd/server_internal.h and silcd/server_util.c.
501 * Notify distribution to backup routers was missing from
502 the silc_server_send_notify_dest function which caused
503 desyncing problems with backup router. Affected file is
506 * The client's channel removing was working wrong on
507 backup router. It assumed that it doesn't know global
508 information but backup router does know. For this reason
509 it could remove channel when it wasn't supposed to do that.
510 Affected file silcd/server.c and silcd/server_util.c.
512 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
514 * Stop for a couple seconds after badkup router has become
515 primary router. Affected file silcd/server.c.
517 * Added silc_server_remove_servers_by_server, which is used
518 to remove servers originated from some other server. Also
519 clients of those servers can be removed too. Affected file
520 silcd/server_util.[ch].
522 * When removing clients after a server has signed of remove
523 also all servers behind that server (unless they are known
524 to be available locally), and send SERVER_SIGNOFF for each
525 of the server separately. Also the signed off clients are
526 sent now separately per signed off server. The affected files
527 are silcd/server.c and silcd/server_util.[ch].
529 * All servers added with silc_idlist_add_server must always
530 have both "router" and "connection" pointers set. Otherwise,
531 bad server entries may be left around in the cache.
532 Affected file silcd/command_reply.c.
534 * Do not create the channel key in NEW_CHANNEL packet
535 processing if the channel is empty. Affected file
536 silcd/packet_receive.c.
538 * Completed backup router support for standalone routers.
539 Supports also servers in the cell that do not use the backup
542 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
544 * Fixed a bug in silc_string_regexify which did not add '^'
545 at the start of each string, and thus the matching was
546 not explicit. For example ban list iikone@*!*@* would
547 match also "priikone", which is wrong, it would have to be
548 *iikone@*!*@* to match also "priikone". Affected
549 file lib/silcutil/unix/silcunixutil.c.
551 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
553 * Enable all local server connections before updating client
554 caches when we've become backup router. Otherwise, signoff
555 packets may not reach the clients. Affected files are
556 silcd/server.c and silcd/server_util.[ch].
558 * Fixed a bug in version string parsing which could crash
559 the program with specially formatted version string.
560 Bug reported and patch provided by Ville Räsänen. Affected
561 file lib/silcutil/silcutil.c.
563 * Handle the disconnection immediately when DISCONNECT
564 packet is received in server. Affected file silcd/server.c.
566 * Primary router now waits a short time (10 seconds) for
567 backup router connection before accepting any other
568 connection (except local). Affected file silcd/server.c,
571 * Fixed a crash in client libary in NICK_CHANGE notify when
572 NICK_CHANGE arrived for client entry we are resolving
573 currently. Affected file lib/silcclient/client_notify.c.
575 * Call the sconn->callback completion even if error had
576 occurred. Start reconnecting always if connection to
577 primary router fails during backup router protocol.
578 Affected files silcd/server.c and server_backup.c.
580 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
582 * Added functions silc_server_send_opers and
583 silc_server_send_opers_notify to send packets stricly
584 to operators. Added macro SILC_SERVER_SEND_OPERS macro
585 to send variable argument notify to operators.
586 Affected files silcd/packet_send.[ch] and silcd/server.h.
588 * Removed UMODE rights checking with UMODE_CHANGE notify.
589 Affected file silcd/packet_receive.c.
591 * Server/router operator now receives notify when network
592 switches to backup router and when it resumes the use of
593 primary router. Affected file silcd/server.c and
594 silcd/server_backup.c.
596 * Fixed the updating of client information after backup
597 resuming protocol is over; update all except local clients
598 to the new primary router. The affected file is
601 * Added support for closing active connections in rehash
602 that were unconfigured by the user. Supports currently
603 closing server and router connections. Affected file
606 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
608 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
610 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
611 is NULL since seems that on some platforms NULL is allowed
612 and on some it's not. Fallback encoding is used instead.
613 Affected file lib/silcutil/silcstrutil.c.
615 * Fixed statistics updating for incoming server connection
616 which could cause problems when re-connecting. Affected
619 * Preliminary backup router support for standalone router
620 added. Affected files in silcd/.
622 * Mark server connections in backup router disabled before
623 and after backup protocol. Affected file is
624 silcd/server_backup.c.
626 * Added support for reconnecting to remote server connection
627 even if the protocol fails, and if the configuration wants
628 us to keep trying to connect anyway.
630 Server connection is not allowed to backup router if
631 backup router does not have connection to primary router yet.
633 Affected file is silcd/server.c.

642 notify only after it's resolved so that all notifys are
643 handled in same order as received from the server.
645 Added similar resolver check to channel entries. Every
646 notify that cause resolving of any information that affects
647 channel entry marks the channel entry in waiting state.
648 After whatever resolving is over the waiters are signalled
649 and only then the notifys are handled in the same order
650 as delivered from the server.
652 Affected files are lib/silcclient/idlist.[ch], and
655 * Fixed KILLED notify handling in normal server. Affected
656 file silcd/packet_receive.c.
658 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
659 is locally connected, or was locally connected (but may
660 be detached and connection is not active). Added also
661 SILC_IS_LOCAL for checking this status. Affected files
662 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,

665 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
667 * Don't send or handle TOPIC_SET if topic is already set and
668 is same as being set. Affected files silcd/command.c and
669 silcd/packet_receive.c.
671 * Fixed CMODE change rights checking to work correctly when
672 removing modes by operator. Affected file is
675 * Fixed some handling with New Channel packet in router and
676 fixed some CMODE_CHANGE notify handling in server and router.
677 Affected file is silcd/packet_receive.c.
679 * Changed "disconnect" client operation to include the
680 reason of the disconnection and optional disconnection
681 message. Affected file lib/silcclient/silcclient.h.
683 * Made the compilation of lib/contrib/ stuff conditional.
684 Affected files configure.in.pre, lib/contrib/Makefile.am.
686 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
688 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
689 to the sender of the notify too, to avoid situation where two
690 notifys are in the network at the same time going to oppsite
691 directions. Affected file silcd/packet_receice.c.
693 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
695 * Delete the client from channel even if the cilent->id is
696 NULL. It was possible that client was deleted without
697 removing from channels (theoretically at least). Affected
698 file silcd/server.c and silcd/server_util.c.
700 * Free the client data too when resuming is not successful.
701 Affected file silcd/packet_receive.c.
703 * Merged some code from c0ffee's silc-plugin. Affected files
704 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
706 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
707 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
708 to the primary router connection, the other one returns
709 TRUE if packet must be broadcasted to network.
711 * All notifys that are destined to primary router (to network)
712 are now automatically sent to backup routers even if the
713 router is standalone (and has backup router). Affected files
716 * Added --without-irssi and --without-silcd configuration
717 options for disabling the compilation of these applications.
718 Affected file configure.in.pre and prepare.

723 UTF-8 encoding and decoding. Added also new encodings
724 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
726 Added also SILC_STRING_LANGUAGE which is language and charset
727 specific encoder and decoer for those platforms that support
728 iconv(). It can convert the UTF-8 to and from the locale
729 specific character set.
731 Affected file lib/silcutil/silcstrutil.[ch].
733 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.

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

783 * When authenticating as founder during JOIN command, check
784 that the one authenticating becomes the only founder on the
785 channel. Affected file silcd/command.c.
787 * Better checking for founder mode setting when CUMODE_CHANGE
788 notify is received. Affected file silcd/packet_receive.c.
790 * Close all connections when shutting down the server by sending
791 DISCONNECT packet. Close all listeners too when shutting
792 down the server. Affected file silcd/server.c.

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

870 * Added error printing of any error that has occurred during
871 any command in client library. Affected file is
872 irssi/src/silc/core/client_ops.c.

1379 * Redefined the Status Payload to include now two 8 bit fields,
1380 instead of one 16 bit field. This now makes it possible to
1381 send list of errors. Updated the protocol specs and the code
1382 in core library, client library and server. Protocol TODO #1.
1383 Affected files are lib/silccore/silccommand.[ch],
1384 lib/silcclient/command_reply.[ch], silcd/command.c,

1414 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1416 * Added STATS command to the protocol after all, to return
1417 various statistical information about the network. It can
1418 be used by clients to retrieve statistical information, and
1419 servers may use it to to fetch cell and network wide
1420 statistics from router. Updated the protocol specs and
1421 implemented it to the server. Protocol TODO #16.
1422 Affected files are lib/silccore/silccommand, silcd/command.[ch],

1427 * The LIST command reply in client libary now adds new channel
1428 entry if the returned channel doesn't exist yet in cache,
1429 and returns the channel entry to the application in the
1430 command_reply client operation. Affected file is
1431 lib/silcclient/command_reply.c.
1433 * Changed the channel message payload's MAC generation to
1434 include the IV in the MAC as well. This way all relevant
1435 parts of the channel message payload are authenticated also
1436 with the channel message MAC (and not only by packet MAC).
1437 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1438 Affected file is lib/silccore/silcchannel.c.
1440 * Fixed the SKE to save the remote version, since the

1515 to define the payload for DATA flag. Added the flags to
1516 the implementation. Protocol TODO #9. Affected file is
1517 lib/silccore/silcchannel.h.
1519 Changed the client library to return the message length
1520 to application as well in the channel_message and private_message

1563 * Some client implementations quit network by doing first LEAVE
1564 and then immediately SIGNOFF (like Bombyx). We now do check
1565 after a short time after LEAVE notify and check whether the
1566 client is still valid after LEAVE, and if not we remove it from
1567 cache. Affected file is lib/silcclient/client_notify.c.
1569 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>

1584 totally saved 16 bytes of memory per context after optimization.
1585 Affected files are lib/silccore/silcpacket.[ch].
1587 * Made strict checks for valid SILC IDs. Affected file is
1588 lib/silccore/silcid.c.
1590 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1592 * Changed the object argument for silc_cipher_register,
1593 silc_hash_register, silc_hmac_register and silc_pkcs_register
1594 to const. Affected files are lib/silccrypt/silccipher.[ch],
1595 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1597 * Changed the silc_get_username and silc_get_real_name to
1598 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1600 * Fixed the Irssi SILC Client to use the silc_get_username and
1601 silc_get_real_name insted of glib routines since the glib
1602 routines only corrupt stack. Fixes the Irssi SILC to work in
1603 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1605 * Fixed the Irssi to not use g_get_home_dir since it crashes
1606 or returns garbage on cygwin and corrupts stack. Added function
1607 get_home_dir to Irssi routines. Affected files are
1608 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1610 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1612 * Made some structure optimizations. SFTP memory FS MemFSEntry
1613 entry structure. Optimized SilcTask structure. Optimized
1614 SilcPacketContext structure.
1616 Affected files lib/silcsftp/sftp_fs_memory.c,
1617 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1619 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1621 * And yet again reverted back the config thing since Johnny
1622 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1625 * Fixed memory leaks from config object. Affected files are
1626 silcd/serverconfig.[ch].
1628 * Added support for adding new connections to the server in rehash.
1629 After rehash they take effect.
1631 Added support for changing the maximum allowed connections in
1632 rehash. The number can grow but going smaller is not supported.
1634 Added function silc_server_num_sockets_by_remote to the
1635 silcd/server_util.[ch].
1637 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1639 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1641 * Added preliminary checking during config parsing for a valid
1642 public/private key and removed further checks in the code.
1643 Affected files are silcd/serverconfig.[ch], server.c.
1645 * Moved functions silc_server_drop() and silc_server_daemonise()
1646 from server.c to silcd.c since they are stricly related to
1647 the application activity.
1649 * Reverted a small part of the automatic ref/unref since
1650 it caused a double unref in some situations. Affected
1651 files are silcd/silcd.[ch], server.c, serverconfig.c.
1653 * Added some .cvsignore files in the lib directory.
1655 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1657 * Fixed silc_net_gethostbyaddr to correctly resolve by
1658 address. Affected file lib/silcutil/silcnet.c.
1660 * Fixed the notify relaying to client. The HMAC to be used
1661 with relayed packets ws wrong and caused decryption failure
1662 at the client end. Affected file is silcd/packet_receive.c.
1664 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1666 * Created new branch silc_protocol_1_0_branch.
1668 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1670 * Changed the silc_server_config_* routines to be SilcServer
1671 independent. They are now officially application specific code
1672 and not part of generic server implementation. Affected files
1673 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1675 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1677 * Added automatic referencing of config context in the
1678 silc_server_config_alloc, and automatic unreferencing in the
1679 silc_server_config_destroy. Affected files are
1680 silcd/serverconfig.[ch], silcd/silcd.c.
1682 * Fixed the silc_log_quick handling in the logging routines.
1683 It didn't log quickly when it was TRUE. Affected file is
1684 lib/silcutil/silclog.c. Also the flush delay was set even
1685 if it was 0 in config file. Affected file is
1686 silcd/serverconfig.c.
1688 * Added support for changing key pair of the server in rehash.
1689 Affected file silcd/server.c.
1691 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1693 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1694 too early, before getting the channel entry. Affected file
1695 is silcd/packet_receive.c.
1697 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1699 * Added functions silc_server_config_[ref/unref], these are used
1700 to prevent that the config object is destroyed.
1702 No longer directly affect global variables silc_log_quick and
1703 silc_log_delay, they are first cached inside the config object
1704 and then applied with silc_server_config_setlogfiles().
1706 silc_server_config_set_defaults() is now internal to
1707 serverconfig.c, there are no reasons to show this internal stuff
1710 Affected files are silcd/serverconfig.[ch].
1712 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1713 fprintf's to stderr, since some code may be executed again after
1714 the server went into the background. Affected files are
1717 * Added rehash support. Added function silc_server_rehash() that
1718 will perform all the basic tasks of the rehashing procedure.
1720 * Added command line option `-x, --hexdump'. This will enable the
1721 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1722 The option `--hexdump' implies `--debug'.
1724 * Fixed a bad bug in the logging APIs (silcutil library) where
1725 the application would crash after calling silc_log_reset_all().
1727 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1729 * Fixed the KICKED notify handling in client library to
1730 correctly remove the channel and all entries from the
1731 channel when I was kicked. This bug crashed the client.
1733 Fixed yet another but in KICKED notify handling to remove
1734 the kicked client correctly from the channel.
1736 Affected file is lib/silcclient/client_notify.c.
1738 * Fixed a minor bug in looking up correct client entry
1739 in KICKED notify in server. Affected file is
1740 silcd/packet_receive.c.
1742 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1743 sources correctly to distribution. Fixes --with-gmp option.
1745 * Removed the manual rehashing from ID Cache, and changed it
1746 to use the SILC Hash Table's auto rehash feature. Affected
1747 file is lib/silccore/silcidcache.c.
1749 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1751 * Fixed a bug in the silc_client_nickname_format function that
1752 handles the multiple same nickname formatting. Two clients
1753 with same nickname caused problems after the first one left
1754 and rejoined. It didn't format the nickname correctly.
1755 Affected file is lib/silcclient/idlist.c.
1757 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1759 * Don't change the topic if olod topic is same as new one.
1760 Affected file is silcd/packet_receive.c.
1762 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1764 * Added cross-reference support to the SILC Documentation
1765 generator. All types across all HTML files are now cross-
1766 referenced. Affected files util/robodoc/generator.c and
1767 scripts/silcdoc/silcdoc.
1769 * Added file lib/silcutil/silctypes.h to include all the
1770 arithmetic type definitions and some macros. Removed
1771 includes/bitmove.h and moved macros to silctypes.h.
1773 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1775 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1777 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1779 * Added `type' argument to silc_id_payload_parse_id function which
1780 now returns the type of the ID to the sent pointer. Affected
1781 file is lib/silccore/silcid.[ch].
1783 * Added check for CMODE_CHANGE notify type that mode change is
1784 allowed by the sender. Affected file silcd/packet_receive.c.
1786 * Added check for CUMODE_CHANGE notify type that mode change is
1787 allowed by the sender. Affected file silcd/packet_receive.c.
1788 Added the ID type as CUMODE_CHANGE notify type as argument
1789 to the `notify' client operation. Affected files are
1790 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1792 * Added function silc_client_add_server to the client library.
1793 Added support for resolving also channel and server info when
1794 received unknown entity in notify packet. Affected files are
1795 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1797 * Added function silc_command_get_status to return the command
1798 status from the command reply's argument payload. Affected files
1799 are lib/silccore/silccommand.[ch].
1801 * Added check for KICKED notify type that the kicking is
1802 allowed by the client. Affected file silcd/packet_receive.c.
1804 * Created function silc_get_input which can be used to get input
1805 (echo on or off) from user on command line. Affected files are
1806 lib/silcutil/silcutil.[ch].
1808 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1810 * Optimized silc_server_packet_relay_to_channel function.
1811 Added new function silc_channel_message_payload_encrypt which
1812 can be called directly if channel message payload needs to
1813 be encrypted and is already encoded (no need to call _encode
1814 function). Packet relaying is now done by router without any
1815 extra memory allocations. Affected files are
1816 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1817 silcd/packet_send.c.
1819 * Fixed the INVITE notify handling. It took wrong arguments
1820 as invite list and invite delete. Affected file is
1821 silcd/packet_receive.c.
1823 * Added check for TOPIC_SET notify type that the topic change is
1824 allowed by the client. Affected file silcd/packet_receive.c.
1826 * Added check for INVITE notify type that inviting is allowed by
1827 the client. Affected file silcd/packet_receive.c.
1829 * Changed the silc_server_client_on_channel to return the
1830 SilcChannelClientEntry as well. Moved the function
1831 silc_server_check_cmode_rights to server_util.[ch].
1832 Affected files are silcd/server_util.[ch], silcd/command.c.
1834 * Added function silc_server_check_umode_rights to check whether
1835 changing client's user mode is allowed. Added check for
1836 UMODE_CHANGE notify type that the umode change is allowed
1837 by the client. Affected files are silcd/server_util.[ch],
1838 silcd/packet_receive.c and silcd/command.c.
1840 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1842 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1843 ID length. It ignored that ID can be IPv6 based as well.
1844 Affected file lib/silccore/silcpacket.h.
1846 * Fixed the silc_id_id2str and silc_id_str2id to take the
1847 IPv6 address offset's into consideration. Affecte file is
1848 lib/silccore/silcid.c.
1850 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1852 * Fixed the internal Unix scheduler functions to check for
1853 NULL context they may receive. The affected file is
1854 lib/silcutil/unix/silcunixschedule.c.
1856 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1858 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1859 can specify different directory with --home command line
1860 parameter. Affected files irssi/src/silc/core/client_ops.c,
1863 * SILC-specific commands aren't now executed if the active server
1864 isn't of SILC-type, so there won't be problems with having
1865 IRC and SILC protocol support in same client. Affected files
1866 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1869 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1871 * Improved the signal support in SILC Schedule. Added new
1872 function silc_schedule_signal_call which is used by application
1873 to mark a signal to be called. It is now safe to perform
1874 any kind of tasks in signal callbacks since it is guaranteed
1875 that the application specified signal callback is called
1876 after the signal is over. Affected files are
1877 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1879 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1881 * Added `name' field to SilcChannelPrivateKey to represent
1882 application given name for the key. Moved also the context from
1883 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1884 Added the `name' argument also to the function
1885 silc_client_add_channel_private_key.
1887 Added function silc_client_current_channel_private_key to set the
1888 current channel private key in use.
1890 Added "change" command to KEY command which can be used to change
1891 the current channel private key. Bound the command also to
1892 alt+K (Alt+Shift+k).
1894 Also affected files lib/silcclient/client_channel.c,
1895 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1897 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1899 * Added silc_rng_get_byte_fast function in to the
1900 lib/silccrypt/silcrng.[ch].
1902 * Changed the interface of silc_packet_assemble and the
1903 silc_packet_send_prepare. If silc_packet_assmble is now
1904 called the application does not call silc_packet_send_prepare
1905 because the library will call it automatically. These
1906 interfaces now also return a reference to the outgoing buffer
1907 which includes the assembled packet, which the application can
1908 use to encrypt the packet.
1910 Affected files are lib/silccore/silcpacket.[ch],
1911 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1912 silcd/packet_send.c, server_backup.c and packet_receive.c.
1914 * Fixed a packet sending bug on very high load, where outgoing
1915 packet queue wasn't handled correctly and packets got corrupted.
1916 Affected files are lib/silcutil/*/silc*sockconn.c,
1917 lib/silcclient/client.c and silcd/server.c.
1919 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1921 * Added macro SILC_PACKET_DATALEN which can be used during
1922 packet assembling to check whether the data to be added to
1923 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1924 len is truncated until it fits it.
1926 Added checks for maximum length of channel message payload and
1927 private message payload also.
1929 Added checks for maximum packet length in server and in
1932 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1933 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1934 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1935 lib/silcclient/client_prvmsg.c.
1937 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1939 * Added silc_server_packet_queue_purge call to the
1940 silc_server_disconnect_remote to assure that all data in the
1941 queue before disconnecting is sent to the network. Affected
1942 file silcd/server.c.
1944 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1946 * Added the deleting of server's own ID cache entry to the
1947 silc_server_free function. Free also everything else that
1948 has been allocated in silc_server_init. The affected file
1951 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1953 * Added functions silc_parse_version_string, silc_version_to_num,
1954 and silc_ske_parse_version to parse SILC protocol style version
1955 strings. Affected files lib/silcutil/silcutil.[ch] and
1956 lib/silcske/silcske.[ch].
1958 * Added new configuration params: version_protocol, version_software
1959 and version_software_vendor to specify what version the remote
1960 host must at least be to be able to connect to server. The vendor
1961 string can be regex matched too. Added new function
1962 silc_server_connection_allowed to check maximum number of allowed
1963 connections, and allowed versions for incoming connections.
1964 Affected files are silcd/server.c, server_util.[ch] and
1967 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1969 * Added preliminary support for signals in scheduler. The
1970 signals we care about are now blocked always when the scheduler
1971 is locked. This way we can synchronise the use of signal with
1972 scheduler. It is guaranteed that when signal occurs the scheduler
1973 is not locked, and thus new tasks can be safely added to the
1976 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1977 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1978 Added new platform specific routines
1979 silc_schedule_internal_signals_[un]block and
1980 silc_schedule_internal_signal_[un]register.
1982 Added new functions to SILC Schedule API:
1983 silc_schedule_signal_[un]register. Each signal that application
1984 is going to use should be registered to the scheduler.
1986 Affected files are lib/silcutil/silcschedule.[ch],
1987 lib/silcutil/*/silc*schedule.c.
1989 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1991 * Check for unauthenticated client and server in the
1992 silc_server_new_client and silc_server_new_server functions.
1993 Affected file silcd/packet_receive.c.
1995 * Added function silc_string_is_ascii to check whether given
1996 string is 7-bit ASCII string. Affected files are
1997 lib/silcutil/silcutil.[ch].
1999 * Added function silc_id_is_valid_server_id into the
2000 silcd/serverid.c and added checking for valid Server ID's in
2001 silc_server_new_server. The Server ID must always be based
2002 on the server's public IP address.
2004 * Added logging of DISCONNECT packet message in the server.
2005 Affected file silcd/server.c.
2007 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2009 * Changed all library interfaces that use Global RNG to also
2010 accept SilcRng as argument. Affected files are
2011 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
2012 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
2013 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
2014 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
2015 lib/silccrypt/rsa.c.
2017 * Added function silc_pkcs_generate_key to the
2018 lib/silccrypt/silcpkcs.[ch] for applications so that they
2019 don't need to do pkcs->pkcs->init calls anymore.
2021 * Remove SilcSocketConnection from the SFTP API since it really
2022 wasn't needed there. The application has the information
2023 saved in its contexts anyway and the SFTP layer doesn't need
2024 know about it. Affected files lib/silcsft/silcsftp.h and
2025 lib/silcsftp/sftp_[server/client].c.
2027 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
2028 The SilcSimContext is not SilcSim.
2030 * Fixed possible buffer overflows in silc_id_render in the
2031 lib/silcutil/silcutil.c.
2033 * On EPOC the global crypto module lists are not used at all
2034 in the crypto library. Added support for using the constant
2035 algorithm list on EPOC. Affected files are
2036 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
2039 * Fixed the handling of third parameter of KICKED notify, since
2040 it was mistakenly updated to SILC Protocol 1.0 even though it
2041 is to be included in 1.1. Since it is not in 1.0 it is not
2042 mandatory, and this fix now handles it only if it is provided,
2043 and it is not error if it is not provided. Affected file
2044 lib/silcclient/client_notify.c.
2046 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2048 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
2049 client. Affected file irssi/src/silc/core/client_ops.c.
2051 * Merged with Irssi 0.8.4 from irssi.org CVS.
2053 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2055 * Check for valid socket connection in client entries before
2056 sending any messages. Fixes a crash, but doesn't fix some
2057 other underlaying bug that is lurking there. Affected
2058 file silcd/packet_send.c.
2060 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
2062 * $usermode, $cumode and $cumode_space expandos shouldn't do
2063 anything with non-SILC server records. Affected file
2064 irssi/src/silc/core/silc-expandos.c
2066 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2068 * Fixed the silc_net_check_[host/local]_by_sock to support
2069 IPv6 bound sockets as well. Now they can return IPv6 addresses
2070 as well. Affected file lib/silcutil/silcnet.c.
2072 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
2073 Affected lib/silcutil/unix/silcunixnet.c.
2075 * Fixed ID rendering (at least on some platforms, not NetBSD)

2082 hash public keys and compare public keys in hash table. Affected
2083 file lib/silcutil/silcutil.[ch].
2085 * Added support for specifying multiple public keys for Client
2086 connection section in server configuration file. This makes it
2087 possible to accept multiple public keys from same host, or to
2088 make a section that accepts any incoming host, and have the
2089 accepted public keys listed in the section.
2091 Added functions silc_sever_[find/get]_public_key, added the
2092 support for this actually to all connection sections but only
2093 the Client section is currently allowed to specify multiple

2204 old name went against naming convention. Applications now
2205 include "silcclient.h" instead of "clientlibincludes.h".
2206 Removed includes/clientlibincludes.h, it is redundant now.
2208 * Renamed includes/version.h to silcversion.h.
2210 * Added really preliminary support for OS/2 into the util
2211 library. Only thread & mutex API is implemented, others

2246 * Added `user_count' to the SilcChannelEntry which now tells the
2247 number of users on the channel. The user count is now saved
2248 in normal server of global channels as well. Affected files
2249 silcd/server.c, idlist.h, packet_receive.c and command.c.
2251 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
2252 include file utility functions.
2254 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
2255 instead of calling directly OS routines.

2268 the SKE interface a bit.
2270 * Fixed padding problem in PKCS#1. The padding was not actually
2271 random since the random number generator was used incorrectly.
2272 This security bug affects only when encrypting with PKCS#1, and
2273 it is not currently used at all in SILC. SILC only use signing
2274 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

2337 Affected files irssi/src/silc/core/silc-core.c,
2338 irssi/src/fe-text/silc.c.
2340 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2342 * Added new configuration options and blocks:
2343 keepalive_secs, reconnect_count, reconnect_interval,
2344 reconnect_interval_max, reconnect_keep_trying and
2345 require_reverser_lookup. Added ConnectionParam block, and
2346 implemented the connection parameters when connecting as
2347 initiator and when accepting connections as responder.

2359 the connection configuration object from the SilcServerConnection
2360 object instead of finding it during the connecting phase.
2361 Added the configuration object to SilcServerConnection struct.
2362 Affected files silcd/server_internal.h, server.c.
2364 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2366 * Add the client on channel after it was resolved at the
2367 channel message receiving, and it was not already on the
2368 channel. Affected file lib/silcclient/client_channel.c.
2370 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2386 authentication to be set at the same time.
2388 Added `prefer_passphrase_auth' setting in config file which
2389 can be used to set to prefer passwd auth if both passwd and
2390 public key is set. If not set, public key is preferred.
2391 This has effect only when being initiator (responder will try
2394 Added support for authentication with passphrase and public key
2395 at the same time. The passphrase is tried first always since
2396 it is faster to check.
2398 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2400 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2446 * Fixed the file transfer's key agreement payload to include
2447 zero port also if the hostname is NULL because it could not
2450 Call file transfer monitor callback now also if error occurs
2451 during key agreement protocol.
2453 Changed the silc_client_file_send interface to return the
2454 SilcClientFileError instead of session id. The session ID
2455 is returned into pointer provided as argument.

2470 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2471 SILC_LOG_WARNING to give out Warning and not Error. Affected
2472 file lib/silcutil/silclog.c.
2474 * Fixed the channel message payload decryption in the function
2475 silc_channel_message_payload_decrypt to not modify the original
2476 buffer before it is verified that the message decrypted
2477 correctly. Otherwise, next time it is called with correct
2478 channel key it won't encrypt since the payload is corrupted.
2479 Affected file lib/silccore/silcchannel.c.
2481 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2493 * Fixed a bug in hash table internal routine for traversing
2494 the table with foreach callback. The current entry may
2495 become invalid in the callback but it was referenced after
2496 the callback returned.
2498 Do not allow auto rehashing of hash table during the
2499 silc_hash_table_foreach operation, for same reasons as it is
2500 not allowed for SilcHashTableList. Affected files are
2501 lib/silcutil/silchashtable.[ch].
2503 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

2524 users list to SilcHashTable. The affected files are
2525 lib/silcclient/idlist.[ch].
2527 * Fixed a bug in hash table tarversing. While the hash table
2528 is traversed with SilcHashTableList the table must not be
2529 rehashed. It is now guaranteed that auto rehashable tables
2530 are not rehashed while tarversing the list. Also defined that
2531 silc_hash_table_rehash must not be called while tarversing
2532 the table. Added function silc_hash_table_list_reset that must
2533 be called after the tarversing is over. The affected files are
2534 lib/silcutil/silchashtable.[ch].
2536 * Changed all hash table traversing to call the new
2537 silc_hash_table_list_reset in server and in client library.
2539 * Added function silc_client_on_channel to return the
2540 SilcChannelUser entry if the specified client entry is joined
2541 on the specified channel. This is exported to application as
2542 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

2547 server. The notify for mode change must be sent always and
2548 not only if !cmd->pending. Affected file silcd/command.c.
2550 * Fixed the WHOWAS command's reply sending to support the
2551 lists correctly. Affected file silcd/command.c.
2553 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2555 * When sending JOIN command to router for processing the
2556 sender's old command identifier was not saved back to the
2557 sender's command context, fixed now. The affected file is
2560 * Create the key in JOIN command of the router did not return
2561 the channel key, added check for this. Affected file is
2564 * Fixed a channel ID update bug in JOIN command reply. Do
2565 not directly upgrade the ID but call the function
2566 silc_idlist_replace_channel_id if the ID was changed.
2567 Affected file silcd/command_reply.c.
2569 * Fixed memory leaks from command calling if it would fail.
2570 Affected file silcd/command.c.

2582 * Removed TRQ from lib/trq, not needed anymore.
2584 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2585 with server connections. Later this will be configurable
2586 in config file after new config file is done. Affected file
2589 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2591 * Fixed a crash in server related to channel announcements.
2592 Affected file silcd/server.c.

2596 * Fixed memory leaks in silc_server_create_new_channel*
2597 functions. Affected file silcd/server.c.
2599 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2600 which ID was changed. This way the router will send the
2601 user list for the channel again, and server won't be in
2602 desync in some rare circumstances. Affected file is
2603 silcd/packet_receive.c.
2605 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2607 * Check for NULL socket pointer in the function
2608 silc_server_packet_send_to_channel_real. Affected file
2609 silcd/packet_send.c.
2611 * Fixed the BAN notify handling to correctly remove ban
2612 list. Affected file silcd/packet_receive.c.
2614 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2616 * Fixed some header addition to Toolkit distribution in
2617 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2619 * Added lib/silcclient/client_ops_example.h as an template
2620 file for application programmers to quickly start using
2621 the SilcClientOperation functions in their application.
2622 Updated the lib/silcclient/README as well to tell about this
2623 nice file made available.
2625 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2627 * Call silc_server_remove_from_channels when removing client
2628 entry when NO_SUCH_CLIENT_ID was received. Affected file
2629 is silcd/command_reply.c.
2631 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2633 * Added server & router operator statistics updating. Affected
2634 file silcd/packet_receive.c and silcd/command.c.
2636 * Fixed the SERVER_SIGNOFF notify handling on normal server
2637 not to save the history information for clients. Same was
2638 fixed earlier in remove_clients_by_server function, but not
2639 here. Affected file silcd/packet_receive.c.
2641 * Raised the default connection-retry count from 4 to 7 in
2642 server. Affected file silcd/server.h.
2644 * Cancel any possible reconnect timeouts when we start the
2645 key exchange. Affected file silcd/server.c.
2647 * Do not reconnect on connection failure when SCONNECT was
2648 given. Affected files silcd/server.[ch].
2650 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2652 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2654 * Fixed the NICK command to always give the unformatted
2655 nickname to the one giving the NICK command. If unformatted
2656 nickname is cached already it will be formatted and the
2657 local entry will always get the unformatted nickname.
2658 Affected file lib/silcclient/idlist.c.
2660 * Fixed some double frees from client library commands.
2661 Affected file is lib/silcclient/command.c.
2663 * Fixed CUMODE command in server to assure that no one can
2664 change founder's mode than the founder itself, there was a
2665 little bug. Affected file silcd/command.c.
2667 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2669 * Removed the SilcClientCommandDestructor from the client
2670 libary, it is not needed anymore. Affected files are
2671 lib/silcclient/silcapi.h, command[_reply].[ch],
2672 client_notify, idlist.c.
2674 * Fixed GETKEY command to first resolve client, and then
2675 resolve the server only if the client was not found, instead
2676 of resolving both at the same time. Affected file is
2677 lib/silcclient/command.c.
2679 * Added silc_client_start_key_exchange_cb and lookup the
2680 remote hostname and IP address before starting the key
2681 exchange with server. The affected file is
2682 lib/silcclient/client.c.
2684 * The server's public key is now saved using the IP address
2685 of the server and not the servername for the filename.
2686 The hostname public key filename is checked as an fall back
2687 method if the IP address based filename is not found.
2689 Fixed the GETKEY command to save the fetched server key
2690 in correct filename.
2692 Print the remote server's hostname now when new key is
2693 received during connection process. Affected file is
2694 irssi/src/silc/core/client_ops.c.
2696 * Return always our own public key to the client if it asks
2697 for it with GETKEY command. Affected file silcd/command.c.
2699 * Removed the use_auto_addr variable from default config
2700 file since it was in wrong section. Affected file is
2703 * Fixed TOPIC_CHANGE notification to not route it when it
2704 was sent using silc_server_send_notify_to_channel function.
2705 Affected file silcd/command.c.
2707 * Fixed silc_server_send_notify_kicked to send the kicker's
2708 Client ID also, it was missing. Affected files are
2709 silcd/command.c, silcd/packet_send.[ch].
2711 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2713 * Do not save client history information in SERVER_SIGNOFF.
2714 Fixes the bug in normal server that it does not detect
2715 the client becoming valid after the server becomes back
2716 online. Affected file silcd/server_util.c.
2718 * Added `sock_error' field into the SilcSocketConnection
2719 context. When error occurs during socket operation (read
2720 or write) the error is saved. Added also new function
2721 silc_socket_get_error to return human readable socket error
2722 message. Affected files are lib/silcutil/silcsockconn.[ch],
2723 lib/silcutil/unix/silcunixsockconn.c, and
2724 lib/silcutil/win32/silcwin32sockconn.c.
2726 * The server now prints the socket error message in the
2727 signoff for client. Affected file silcd/server.c.
2729 * Fixed the `created' channel information sending from router
2730 to server in JOIN command. Checks now whether the channel
2731 really was created or not and set it according that.
2733 Fixed the JOIN command to use the client entry's current
2734 ID during the joining procedure instead of the one it sent
2735 in the command (it is checked though), since it can change
2736 between the packet processing and command processing, and
2737 would just case unnecessary pain in the client end. Affected
2738 file silcd/command.c.
2740 * Fixed a channel key payload sending to use correct channel
2741 ID when the server was forced to change the channel's ID by
2742 router. Router sent the key payload with the old Channel ID.
2743 Affected file silcd/packet_receive.c.
2745 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2747 * Call silc_server_save_channel_key only if the key payload
2748 was provided in the JOIN command's command reply. Affected
2749 file silcd/command_reply.c.
2751 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2753 * Fixed silc_mp_sizeinbase to return the value correctly with
2754 MPI. Affected file lib/silcmath/mp_mpi.c.
2756 * Fixed the stop_server signal to correctly stop the scheduler
2757 and gracefully stop the server when SIGTERM or SIGINT signals
2758 are received. Affected file silcd/silcd.c.
2760 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2762 * Simple handling of TERM and HUP signals. Also added some log
2763 flushing call around. Affected file is
2766 * Fixed small bugs in silclog.c. Now buffering output will take
2767 effect after 10 seconds since startup: This will ensure that
2768 no important startup messages are lost. Also output redirection
2769 will preserve original format ([Date] [Type] message).
2770 Affected file is lib/silcutil/silclog.c.
2772 * Added two options to the config file, in the logging section:
2773 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2774 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2776 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2778 * Do not print the warning about log files not being initialized
2779 more than once to avoid excess logging. Affected file is
2780 lib/silcutil/silclog.c.
2782 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2783 the SIM copying in make install in Makefile.am.pre.
2785 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2787 * Rewritten silclog APIs. Globally interesting changes follows:
2788 silc_log_set_files() changed to silc_log_set_file().
2789 silc_log_set_callbacks() changed to silc_log_set_callback().
2790 ROBOdoc documented silclog header file.
2791 SilcLogCb now returns bool to wether inihibit the default
2792 handler or not (to keep the old behaviour return always TRUE).
2793 The new APIs should also fix the problem of the
2794 silcd_error.log file that was written in the current directory.
2797 Log files streams will remain opened after silc_log_set_file()
2798 call, means less CPU usage notably on high traffic servers.
2799 File streams are now full buffered, and flushed to the disk
2800 every 5 minutes, lesses HD activity and CPU usage.
2801 Messages can be redirected, allowing admins to configure
2802 one single logfile for all server messages.
2803 the silc_log_quick global variable to activate fast-logging.
2804 Affected files lib/silcutil/silclog.[ch]
2806 * Changed some code to conform new silclog APIs. Affected
2807 files are doc/example_silcd.conf.in, silcd/server.c
2808 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2811 * Fixed a memory leak that could occur in some situations.
2812 Affected file silcd/serverconfig.c.
2814 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2816 * Added the silc_client_del_client to remove the client from
2817 all channels as well. Affected file lib/silcclient/idlist.c.
2819 * Fixed the client library to correctly remove the client
2820 from all channels when the client entry is being destroyed.
2821 Affected file lib/silcclient/client_notify.c, command.c.
2823 * Added auto-nicking support to the client library. If the
2824 applicatio now sets client->nickname it will be sent to the
2825 server after connecting by the library. This way for example
2826 SILCNICK (or IRCNICK) environment variables will have effect
2827 and always change the nickname automatically to whatever
2828 it is wanted. Affected file lib/silcclient/client.[ch].
2830 * Renamed silc_server_command_bad_chars to the
2831 silc_server_name_bad_chars and moved it to the
2832 silcd/server_util.[ch]. Added also new function
2833 silc_server_name_modify_bad to return nickname that
2834 includes bad characters as new nickname without those
2835 bad characters. This check and modify is now used in
2836 silc_server_new_client when the username is initially set
2837 as nickname, so it must be checked to be valid nickname.
2838 Affected file silcd/packet_receive.c.
2840 * The nickname length is now taken from the packet for real
2841 and not trusted to strlen() since it clearly can return
2842 wrong length for nickname including bad characters. This
2843 also applies to channel names. Affected file silcd/command.c.
2845 * Removed the lib/silcsilm/modules directory. Modules are now
2846 compiled into the lib/silcsim. Fixed the copying of the
2847 modules to follow symbolic links in Makefile.am.pre.
2849 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2851 * Fixed silc_string_regexify list creation. Fixes bugs with
2852 BAN and INVITE commands in server. The affected file is
2853 lib/silcutil/unix/silcunixutil.c.
2855 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2857 * Removed the command destructor entirely from the server's
2858 command and command reply routines. It is not needed, and
2859 its usage was buggy and caused crashes. Affected files are
2860 silcd/command[_reply].[ch].
2862 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2864 * Cancel protocol and NULL sock->protocol if timeout
2865 occurred during protocol. Affected file silcd/server.c.
2867 * Cancel protocol timeouts always before calling the final
2868 callback, to assure that after final callback is called
2869 no other state will be called for the protocol anymore.
2870 Affected file silcd/protocol.c.
2872 * Print error log if incoming connection configuration could
2873 not be found. Affected file silcd/server.c.
2875 * Fixed JOIN command to correctly save the founder mode
2876 to the client on normal SILC server, when the channel
2877 was created by the router. Affected file silcd/command.c.
2879 * Fixed LIST command (hopefully) to send correct reply
2880 packets. Affected file silcd/command.c.
2882 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2884 * The silc_packet_receive_process now returns FALSE if the
2885 read data was invalid packet, and TRUE if it was ok.
2887 The server now checks that if unauthenticated connection
2888 sends data and its processing fails the server will close
2889 the connection since it could be a malicious flooder.
2891 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2893 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2895 * Make sure the warning about error opening a log file is
2896 printed only once and not everytime it fails (produces
2897 too much useless log). Affected file lib/silcutil/silclog.c.
2899 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2901 * Made the silc_server_daemonise() function more readable.
2902 Affected file silcd/server.c.
2904 * Pid file is now optional, the user may comment it out from
2905 the config file. Removed define SILC_SERVER_PID_FILE, we
2906 don't need a default any longer. Affected file
2907 configure.in.pre, lib/Makefile.am.pre.
2909 * Make some use of the pid file. The server now dies at startup
2910 if it detects a valid pid file on his path. The server would
2911 die anyway in this circumstance, because of the bind() failure.
2912 Affected file silcd/silcd.c.
2914 * No longer compiling lib/dotconf.
2916 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2918 * Fixed JOIN command parsing not to crash. Affected file
2919 lib/silcclient/command.c.
2921 * Fied the NICK_CHANGE notify to add the new client entry
2922 even it is resolved. This removes an <[unknown]> nick
2923 thingy bug in the client. Affected file is
2924 lib/silcclient/client_notify.c.
2926 * Do not try to allocate 0 bytes (efence does not like it)
2927 in lib/silccore/silccomand.c when encoding payload.
2929 * Do not take IRCNICK as nickname in Irssi SILC client since
2930 it is not possible to set nickname before hand connecting
2931 the server (TODO has an entry about adding auto-nicking
2934 * Changed the silc_server_command_pending to check whether
2935 there already exists an pending entry with the specified
2936 command, command identifier and pending callback. This is
2937 to fix IDENTIFY and WHOIS related crashes that may register
2938 multiple pending commands with same identifier. Affected
2939 file silcd/command.c.
2941 * Fixed the server to reconnect to the router even if it
2942 was already reconnecting and EOF was received. This to
2943 fix a possibility that the server wouldn't ever try to
2944 auto-reconnect to the router. Affected file silcd/server.c.
2946 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2948 * Fixed the server's password authentication to use the
2949 length of the locally saved password, and not the one
2950 sent in the packet. Affected file silcd/protocol.c.
2952 * Fixed same password authentication problem in the
2953 Authentication Payload handling routines in
2954 lib/silccore/silcauth.c.
2956 * Yet another password authentication problem fixed with
2957 channel password handling in silcd/command.c.
2959 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2961 * If first character of string in silc_parse_userfqdn is '@'
2962 then do not parse it. Affected file is
2963 lib/silcutil/silcutil.c.
2965 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2967 * Fixed minor bug in IDENTIFY command reply sending, which
2968 caused various weird problems during JOIN when it was
2969 resolving names for users. Affected file silcd/command.c.
2971 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2973 * Fixed the IDENTIFY command reply sending to chech better valid
2974 clients. It was possible to send incomplete list of replies.
2975 Affected file silcd/command.c.
2977 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2979 * Added silc_client_command[s]_[un]register functions now to
2980 dynamically register the commands in client library. Removed
2981 the static table of commands. This allows the client library
2982 to call commands without causing the application to know about
2983 what commands library has called.
2985 Removed the INFO command reply kludge to detect when the command
2986 was called by library. Now library use its own command reply
2987 function for INFO command.
2989 Added function silc_client_command_call to call a command.
2990 Application can use it to call command, not access the structure
2993 Now all commands that are sent by the client library (not
2994 explicitly sent by application) use own command reply functions.
2996 Affected files around lib/silcclient/ and in
2997 irssi/src/silc/core/.
2999 * Fixed the WHOIS command reply sending to chech better valid
3000 clients. It was possible to send incomplete list of replies.
3002 Fixed the WHOIS and IDENTIFY to send the request to router
3003 if normal server did not do it and did not find any results.
3005 Affected file silcd/command.c.
3007 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3009 * Moved the internal data from SilcClient context into its
3010 own file, not accesible to application. Affected files
3011 lib/silcclient/client.h and lib/silcclient/client_internal.h,
3012 and other files in client library.
3014 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3016 * Added doc/examples installation target in Makefile.am.pre.
3019 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3021 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
3022 commands the found client entry will be removed from the
3023 cache, after notifying application about the error. Affected
3024 file lib/silcclient/command_reply.c.
3026 * Changed the /MSG to check for exact nickname user gave, and
3027 not let `nick' match `nick@host' if it is only one found. Now,
3028 user must type the exact nickname (like nick@host2) even if
3029 there are no more than one same nicks found. This is to avoid
3030 a possibility of sending nickname to wrong nickname since
3031 `nick' could match `nick@host'. Affected file is
3032 irssi/src/core/silc-servers.c.
3034 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3036 * Do not print "you are now server operator" or similar when
3037 giving /away command. Affected files are
3038 irssi/src/silc/core/client_ops.c, silc-servers.h.
3040 * Made the silc_server_command_pending_error_check to send
3041 the same command reply payload it received back to the
3042 original sender of the command. This way all arguments
3043 that was received by the server will be received by the
3044 client too. Affected file silcd/command.c.
3046 * Added the silc_idcache_add to return the created cache entry
3047 to a pointer. Affected file lib/silccore/silcidcache.[ch].
3049 * Add global clients to expire if they are not on any channel.
3050 This is because normal server will never know if they signoff
3051 if they are not on any channel. The cache expiry will take
3052 case of these entries. This is done by normal servers only.
3053 The affected files are silcd/command_reply.c,
3054 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
3056 * If server receives invalid ID notification for WHOIS or
3057 IDENTIFY and the ID exists in the lists, it is removed.
3058 Affected file silcd/command_reply.c.
3060 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
3061 in client then client entry that it matches is searched and
3062 the nickname is printed on the screen for user. Affected
3063 file irssi/src/silc/core/client_ops.c.
3065 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3067 * Use cache entry expire time in the LIST command reply to
3068 purge old entries from the cache after the LIST command
3069 reply has been received. This way we don't have non-existent
3070 entries in the cache for too long. Affected file is
3071 silcd/command_reply.c.
3073 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3075 * If we are normal server, and we've not resolved client info
3076 in WHOIS or IDENTIFY from router, and it is global client,
3077 we'll check whether it is on some channel. If it is not
3078 then we cannot be sure about its validity and will resolve it
3079 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
3080 file silcd/command.c.
3082 * Search channel by name (if possible) rather than by ID
3083 in IDENTIFY command's command reply. Affected file is
3084 silcd/command_reply.c.
3086 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3088 * Distribute to the channel passphrase in CMODE_CHANGE notify.
3089 Updated specs and implemented it. Affected file silcd/command.c,
3090 silcd/packet_send.c and silcd/packet_receive.c.
3092 * Implemented the <founder auth> payload handling in the JOIN
3093 command. If provided all conditions for channel joining
3094 except requirement to provide correct passphrase can be
3095 overrided by the channel founder. Updated the protocol specs.
3096 Affected file silcd/command.c.
3098 Added support for founder auth in JOIN command in client
3099 library. Fixed the parsing of the JOIN command now to support
3100 all options as they should be. The affected file is
3101 lib/silcclient/command.c.
3103 * Optimized the WHOIS and IDENTIFY commands to send the request
3104 to router only if it includes nicknames or other names. If
3105 they include only IDs then check the local cache first before
3106 routing. Affected file is silcd/command.c.
3108 * Added channels topic announcements. Affected file is
3109 silcd/packet_receive.c and silcd/server.c.
3111 * Fixed the silc_server_send_notify_topic_set to really destine
3112 the packet to channel. Affected file silcd/packet_send.c.
3114 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
3115 library. Affected file lib/silcclient/client_notify.c.
3117 * Added UMODE announcements. Affected file silcd/server.c.
3119 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3121 * Memory leak fixes in:
3123 lib/silcutil/silcsockconn.c
3124 lib/silcske/silcske.c
3125 lib/silcske/groups.c
3127 lib/silccrypt/silcpkcs.c
3128 lib/silccore/silccommand.c
3129 lib/silccore/silcidcache.c
3134 * ROBOdoc documented the lib/silcske/groups.h file and a
3135 bit changed the interface for better.
3137 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3139 * Update the client entry context in the ID cache after
3140 nick change. Affected file lib/silcclient/command.c.
3141 Fixes the CUMODE command when regaining founder privileges,
3142 and a little WHOIS problem.
3144 * Fixed silc_net_gethostbyname to correctly call the
3145 inet_ntop. Affected file lib/silcutil/silcnet.c.
3147 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3149 * Added IPv6 support checking to the configure.in.pre, added
3150 also --enable-ipv6 option to override the check. Affected
3151 file configure.in.pre.
3153 * The silc_thread_create now calls the start function
3154 directly if threads support is not compiled in. Removes
3155 ugly #ifdef's from generic code. Affected files are
3156 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
3158 * Added silc_net_gethostby[name/addr]_async to asynchronously
3159 resolve. Affected files are lib/silcutil/silcnet.[ch].

3170 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
3171 routines. Added silc_net_is_ip[4/6]. Affected file is
3172 lib/silcutil/unix/silcunixnet.c. All routines that take
3173 address as argument now supports both IPv4 and IPv6 addresses.
3175 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3177 * Fixed LIST command reply sending in server. Affected file
3180 * Server now sends the kicker's client ID in the KICK notify
3181 to the kicked client. Affected file silcd/command.c.
3183 * The client library now parses the kickers client ID and
3184 UI displays it. Affected files lib/silcclient/client_notify.c
3185 and irssi/src/silc/core/silc-channels.c, module-formats.c.
3187 * Made all payload parsing function prototypes consistent.
3188 They all take now const unsigned char * and uint32 pair as
3189 the payload data instead of SilcBuffer. Changes all around
3190 the source tree. Other unsigned char* -> const unsigned char*
3191 changes around the tree as well.
3193 * Optimized SFTP client and server packet sending not to
3194 allocate new buffer for each packet but to recycle the
3195 first allocated buffer. Affected files are
3196 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
3198 * Optimized the SFTP client to use SilcList instead of
3199 SilcDList for requests, because it is faster. Affected file
3200 is lib/silcsftp/sftp_client.c.
3202 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
3203 into lib/silccore/silcid.[ch].
3205 Renamed silcpayload.[ch] into silcargument.[ch].
3207 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3209 * If client entry is deleted with active key agreement
3210 session, abort the session.
3212 The silc_client_abort_key_agreement now calls the completion
3213 callback with new SILC_KEY_AGREEMENT_ABORTED status.
3215 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
3218 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3220 * Don't use __restrict in older GCC's. Affected file is
3221 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
3223 * silc_net_localhost now attempts to reverse lookup the
3224 IP/hostname. Affected file lib/silcutil/silcnet.c.
3226 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
3227 command. It can be used to gain founder privileges at
3228 the same time when joining the channel.
3230 Defined that the SILC_NOTIFY_TYPE_KICKED send the
3231 kicker's client ID as well. Updated protocol specs.
3233 Defined that the server must send SILC_COMMAND_IDENTIFY
3234 command reply with error status to client who sent
3235 private message with invalid client ID.
3237 Updated the protocol specification.
3239 * Added silc_server_send_command_reply to send any
3240 command reply. Affected file silcd/packet_send.[ch].
3242 * Added silc_id_payload_encode_data to encode ID payload
3243 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
3245 * The server now send IDENTIFY command reply with error
3246 status if client ID in private message is invalid. Affected
3247 file silcd/packet_receive.c.
3249 * Save the server key file with server's IP address in
3250 the filename instead of hostname. The affected file is
3251 irssi/src/silc/core/client_ops.c.
3253 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3255 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
3258 * Added libtool support for compiling shared objects in
3259 lib/silcsim. Affected file configure.in.pre and
3260 lib/silcsim/Makefile.am. Original patch by cras.
3262 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3264 * Pid file configuration, and server's config file fixes
3265 patch by toma. Updated CREDITS file.
3267 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3269 * Fixed silc_client_channel_message to not try to decrypt
3270 the message twice if it resolved the destination client
3271 information. This could cause of dropping one channel
3272 message. Affected file lib/silcclient/client_channel.c.
3274 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3276 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3277 lib/silcclient/client.c. This function is used when the SILC
3278 Client is run under some other scheduler, or event loop or
3279 main loop. On GUI applications, for example this may be
3280 desired to used to run the client under the GUI application's
3281 main loop. Typically the GUI application would register an
3282 idle task that calls this function multiple times in a second
3283 to quickly process the SILC specific data.
3285 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3287 * Fixed silc_server_drop() for dropping the supplementary
3288 groups as well, this could cause a security hole on some
3291 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3293 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
3296 * Write PID file after dropping privileges. Added -F option
3297 to run server on foreground. A patch by debolaz.
3298 Affected files silcd/server.c, silcd/silcd.c.
3300 * Fixed MOTD to return the MOTD file server name. Affected
3301 file silcd/command.c.
3303 * Added INFO command reply handling to the Irssi SILC Client.
3304 Affected file irssi/src/silc/core/client_ops.c.
3306 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3308 * Fixed the silc_idcache_list_* routines to really support
3309 the dynamic list. Fixes a crash. Affected file is
3310 lib/silccore/silcidcache.c.
3312 * Fixed the LIST command reply to really call LIST command's
3313 pending callbacks. Affected file silcd/command_reply.c.
3315 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3317 * Update conn->local_entry->nickname after giving NICK
3318 command. Affected file lib/silcclient/command.c.
3320 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3322 * Added the [pid] option to the silcd configuration file
3324 Affected files: serverconfig.[ch] and silcd.c
3326 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3328 * Save fingerprint in WHOIS command reply in server.
3329 Affected file silcd/command_reply.c.
3331 * Fixed NICK commands pending callback registration.
3332 Affected file lib/silcclient/command.c.
3334 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3336 * Use ++server->cmd_ident when sending commands in server,
3337 instead of random number. Affected file silcd/command.c.
3339 * Fixed GETKEY command reply to call actually GETKEY pending
3340 command callbacks. Affected file silcd/command_reply.c.
3342 * A bit stricter check for nicknames. Check for same nickname
3343 in NICK command also. Affected file silcd/command.c.
3345 * Do not call INFO command everytime client ID changes, only
3346 during first connecting. Affected file lib/silcclient/client.c.
3348 * Set the new nickname only after successful command reply for
3349 NICK command is returned by server. Affected file
3350 lib/silcclient/command.c.
3352 * Remove nicknames from nicklist during server_signoff notify.
3353 Should fix /NAMES bit more. The affected file is
3354 irssi/src/silc/core/silc-channels.c.
3356 * Added `fingerprint' field to the SilcIDListData in the
3357 silcd/idlist.h to hold the fingerprint of the client's
3360 Send the fingerprint of the client's public key in WHOIS
3363 Affected files silcd/command.c, and silcd/idlist.[ch].
3365 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3366 create fingerprint from given data.
3368 * Show the fingerprint of the client's public key in WHOIS.
3369 Affected files irssi/src/module-formats.[ch] and
3370 irssi/src/silc/core/client_ops.c.
3372 * Format the multiple same nicknames also during JOIN and
3373 NICK_CHANGE notifys. Affected file is
3374 lib/silcclient/client_notify.c.
3376 * Do not print error on screen for invalid private message
3377 payload since it can come if someone is sending private
3378 messages with wrong key. Affected file
3379 lib/silccore/silcprivate.c.
3381 * Fixed multiple concurrent /PING crash. Affected file
3382 lib/silcclient/command.c.
3384 * Changed the wrong ID encoding. All IP addresses must be
3385 in MSB first order in encoded format. They were encoded
3386 wrong and was in LSB format. Affected files are
3387 silcd/serverid.c, lib/silcutil/silcutil.c.
3389 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3391 * Call the `connect' client operation through the scheduler
3392 in case of error. Affected file lib/silcclient/client.c.
3394 * Call the `failure' client operation even if the error
3395 occurred locally during a protocol. Affected file is
3396 lib/silcclient/protocol.c.
3398 * Added support of sending LIST command to router from normal
3399 server. This way normal server can get list of all channels
3400 in the network too. Fixed the channel list sending in the
3401 server too. Affected files are silcd/command.c, and
3402 silcd/command_reply.[ch].
3404 * Added silc_server_update_channels_by_server and
3405 silc_server_remove_channels_by_server. They are used during
3406 disconnection of primary router and in backup router protocol.
3407 Affected file silcd/server_util.[ch], silcd/server.c and
3408 silcd/server_backup.c.
3410 * Fixed channel adding to global list in IDENTIFY command
3411 reply in server. Affected file silcd/command_reply.c.
3413 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3415 * If the incoming packet type is REKEY or REKEY_DONE process
3416 that packet always synchronously. Fixes yet another MAC
3417 failed error on slow (dialup) connections. Affected file
3418 lib/silcclient/client.c and silcd/server.c.
3420 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3422 * Call check_version SKE callback for initiator too. Affected
3423 file lib/silcske/silcske.c.
3425 * Implemented fix for security hole found in the SKE that was
3426 fixed in the specification few days back; the initiator's
3427 public key is now added to the HASH value computation.
3428 Added backwards support for the old way of doing it too, for
3429 old clients and old servers. Affected file is
3430 lib/silcske/silcske.c.
3432 * Enabled mutual authentication by default in SKE. If initiator
3433 is not providing mutual authentication the responder will
3434 force it. This will provide the proof of posession of the
3435 private key for responder. The affected files are
3436 lib/silcclient/protocol.c and silcd/protocol.c.
3438 * Do not cache anymore the server's public key during SKE.
3439 We do mutual authentication so the proof of posession of
3440 private key is done, and if the server is authenticated in
3441 conn auth protocol with public key we must have the public
3442 key already. Affected file silcd/protocol.c.
3444 * Added new global debug variable: silc_debug_hexdump. If
3445 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3446 file lib/silcutil/silclog.[ch].
3448 * Fixed compilation warning due to char * -> const char *.
3449 Affected files lib/silcutil/silcnet.h, and
3450 lib/silccore/silcauth.[ch].
3452 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3454 * Fixed CMODE command when new channel key was created. If
3455 the creation failed the old key was removed. Next time giving
3456 same command would crash the server since the old key was
3457 freed already. Affected file silcd/command.c.
3459 * Fixed the silc_server_announce_get_channels to not crash
3460 on reconnect. Affected file silcd/server.c.
3462 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3464 * Added silc_log_set_debug_string function to set a regex
3465 string to match for debug output. Only the function names,
3466 or filenames matching the given debug string is actually
3467 printed. This way it is possible to filter out those debug
3468 strings that user is not interested in.
3470 Fixed a bug in silc_string_regexify.
3472 Affected files lib/silcutil/silclog.[ch], and
3473 lib/silcutil/unix/silcunixutil.c.
3475 * Changed the -d options in both server and Irssi SILC client
3476 to take the debug string as argument. Affected files
3477 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3479 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3481 * Added silc_hash_babbleprint to create a Bubble Babble
3482 Encoded fingerprint. The encoding is developed by Antti
3483 Huima (draft-huima-babble-01.txt), and it creates human
3484 readable strings out of binary data. Affected file
3485 lib/silccrypt/silchash.[ch].
3487 * Print the babble print now in addition of fingerprint as well
3488 in Irssi SILC client. Affected files are
3489 irssi/src/fe-common/silc/module-formats.[ch],
3490 irssi/src/fe-common/silc/core/client_ops.c.
3492 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3494 * Fixed a security problem found in SKE. The initiator's
3495 public key too is now added to the HASH hash value creation
3496 which is signed by the responder to create the SIGN value.
3497 This will prevent anyone in the middle to lie to the responder
3498 about the initiator's public key. If this is done now, the
3499 man in the middle will get caught. Updated the protocol
3502 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3504 * Better installation directory handling. Configure module
3505 paths and other paths automatically to example_silc* files
3506 in doc/. A patch by toma.
3508 * Fixed compiler warning from MPI library, and from SILC RNG.
3511 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3512 It can be configured with ./configure. A patch by toma.
3514 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3516 * Find correct make to use in prepare-clean. A patch by
3517 toma. Affected file prepare-clean.
3519 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3521 * Added irssi variables use_auto_addr, auto_bind_ip,
3522 auto_bind_port and auto_public_ip.
3524 * Changed the interface for silc_client_send_key_agreement
3525 in lib/silcclient/silcapi.h
3529 irssi/src/silc/core/silc-core.c
3531 lib/silcclient/silcapi.h
3532 irssi/src/silc/core/silc-channels.c
3533 lib/silcclient/client_keyagr.c
3536 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3538 * Added silc_pkcs_public_key_compare to compare two
3539 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3541 * Check that the client who set the founder mode on the
3542 channel is the same client that is giving the founder
3543 mode to itself. It is done by comparing the saved public
3544 key (it is saved even in the authentication is passphrase).
3545 Affected file silcd/command.c.
3547 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3549 * Do not process packet for disconnected socket connection.
3550 Affected file lib/silccore/silcpacket.c.
3552 * Process the DISCONNECT packet through scheduler in the
3553 client library. Affected file lib/silcclient/client.c.
3555 * Fixed the silc_client_packet_parse to not to increase
3556 the packet sequence number if the conn->sock and the
3557 current socket connection is not same. This can happen
3558 for example during key agreement when the conn includes
3559 multiple socket connections (listeners). Affected file
3560 lib/silcclient/client.c.
3562 * The sender of the file transfer request now provides also
3563 the pointer (listener) for the key exchange protocol. If
3564 the listener cannot be created then it sends empty key
3565 agreement and lets the receiver provide the listener.
3567 Added `local_ip' and `local_port' arguments to the
3568 silc_client_file_send. If they are provided they are used,
3569 if not then it will attempt to find local IP address, if
3570 not found or bind fails then the remote client will provide
3573 Affected files are lib/silcclient/client_ftp.c and
3574 lib/silcclient/silcapi.h.
3576 * Extended the FILE SEND command to support defining the
3577 local IP and port for key exchange listener. They are
3578 optional. Affected file irssi/src/silc/core/silc-servers.c.
3580 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3582 * Defined to WHOIS command reply the sending of fingerprint
3583 of the client's public key (if the proof of posession of the
3584 corresponding private key is verified by the server).
3585 Updated to the protocol specification.
3587 * Added support of receiving the client's public key's
3588 fingerprint in command reply in client library. Affected
3589 file is lib/silcclient/command_reply.c, and
3590 lib/silcclient/idlist.[ch].
3592 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3594 * Do not send over 128 chars long nickname to the server
3595 in NICK command. Affected file lib/silcclient/command.c.
3597 * Do not send over 256 chars long channel names to the server
3598 in JOIN command. Affected file lib/silcclient/command.c.
3600 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3602 * Assure that silc_server_close_connection cannot be called
3603 twice for same socket context. Affected file is
3606 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3608 * Send error message to application if opening file for
3609 writing during file transfer fails. Affected file is
3610 lib/silcclient/client_ftp.c.
3612 Remove all file transfer sessions for a client that we're
3613 removing from ID cache.
3615 Affected file is lib/silcclient/client_ftp.c.
3617 * Fixed silc_net_addr2bin to return correct address. Affected
3618 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3620 * Fixed file transfer session removing on signoff notify.
3621 Affected file irssi/src/silc/core/silc-servers.c.
3623 * Added the SilcClientFileError to be returned in the monitor
3624 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3625 Affected file lib/silcclient/silcapi.h.
3627 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3629 * Fixed a crash in silc_client_ftp_free_sessions and
3630 silc_client_ftp_session_free_client. Affected file
3631 lib/silcclient/client_ftp.c.
3633 * Added `disabled' field in the SilcChannelEntry in the server
3634 to indicate if the server entry is disabled. Affected file
3635 silcd/idlist.h, silcd/command[_reply].c.
3637 * SILC server adds now /var/run/silcd.pid everytime it is
3638 started. Affected file silcd/silcd.c.
3640 * Added silc_server_packet_send_clients to send a packet to
3641 the provided table of client entries. Affected file
3642 silcd/packet_send.[ch].
3644 * Fixed a crash in client resolving in client_prvmsg.c in
3645 client library. Affected file lib/silcclient/client_prvmsg.c.
3647 * Do not actually remove the client directly from ID cache
3648 during SERVER_SIGNOFF, but invalidate it. This way we
3649 preserve the WHOWAS info for the client. Affected file
3650 silcd/server_util.c.
3652 * Fixed SERVER_SIGNOFF notify handling in the server. The
3653 server is now able to process incoming SERVER_SIGNOFF notify
3654 for a server that it doesn't even know about. It will remove
3655 the clients provided in the notify. Affected file
3656 silcd/packet_receive.c.
3658 * Check for partial packet in data queue after every packet that
3659 was found from the queue. Return and wait for more data if
3660 there is partial data in queue. Affected file is
3661 lib/silccore/silcpacket.c.
3663 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3665 * Added SilcClietFileError enum to indicate error in

3678 irssi/src/fe-common/silc/module-formats.[ch].
3680 * Wrote a help file for FILE command.
3682 * Added silc_rng_global_get_byte_fast to get not-so-secure
3683 random data as fast as possible. Random data is read from
3684 /dev/urandom if available and from the SILC RNG if not
3685 available. It is used in padding generation. Affected file
3686 lib/silccrypt/silcrng.[ch].
3688 * All packets in client library are now processed synchronously.

3701 * Assure that silc_client_notify_by_server_resolve does not
3702 resolve the client information multiple times. If it cannot
3703 be found by the first it cannot be found at all. Affected
3704 file lib/silcclient/client_notify.c.
3706 * Fixed WHOWAS command reply calling. Affected file
3707 lib/silcclient/command_reply.c.
3709 * Removed all references to silc_idlist_get_client from the
3710 Irssi SILC client since that call is internal call used by
3711 the library. The Irssi SILC client will use now client
3712 retrieval functions found in silcapi.h.
3714 * Fixed a bug in resolving nickname info before sending
3715 private message. It used freed memory. Affected file
3716 irssi/src/silc/core/silc-servers.c.

3737 * Added silc_net_localip to return local host's IP address.
3738 Affected file lib/silcutil/silcnet.[ch].
3740 * If key exchange or rekey protocol is active for a connection
3741 parse all packets syncronously since there might be packets
3742 in packet queue that we are not able to process without first
3743 processing packets before them. Affected file silcd/server,
3744 lib/silcclient/client.c.
3746 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3747 whether library should continue processing the packet.
3748 Affected file lib/silccore/silcpacket.h.

3794 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3795 is incomplete and is being resolved, it won't be resolved
3798 Make sure also that USERS command reply does not resolve
3799 twice information. Affected file is
3800 lib/silcclient/command_reply.c.
3802 Make sure that silc_client_get_clients_by_list does not
3803 resolve twice same information.
3805 * Check for valid client->id in the silc_server_free_client_data.
3806 Affected file silcd/server.c.
3808 * Fixed /GETKEY nick@server not to crash if the server entry
3809 is not found. Affected file lib/silcclient/command.c.

3817 Affected file silcd/command.c.
3819 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3821 * Call the silc_server_udpate_servers_by_server in the
3822 primary router that comes back online in the backup resuming
3823 protocol. Otherwise it routes packets wrong. Affected file
3824 silcd/server_util.[ch], silcd/server_backup.c.
3826 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3828 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3829 lib/silcutil/silcbuffmt.[ch].
3831 * Redefined the SILC packet header to include the padding
3832 length. Affected file lib/silccore/silcpacket.[ch].
3834 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3835 length for maximum padding up to 128 bytes). Affected
3836 file lib/silccore/silcpacket.h.
3838 * Removed all backwards support for old 0.5.x MAC thingies.
3839 The SILC packet header change makes it impossible to be
3840 backwards compatible.
3842 * Send the ENDING packet with timeout in the backup resuming
3843 protocol. This is to assure that all routers has connected
3844 to the primary router. Affected file silcd/server_backup.c.
3846 * Changed the RNG to take the first IV from random data. It
3847 used to take it from zero actually. Changed the RNG also
3848 to use /dev/urandom during session. /dev/random is used
3849 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3851 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3853 * Changed the SILC packet header to have the first two bytes
3854 (the packet length) encrypted. Affected files aroung the
3855 code tree, lib/silccore/silcpacket.[ch]. Removed the
3856 SilcPacketCheckDecrypt callback. It is not needed anymore
3857 since the silc_packet_receive_process will determine now
3858 whether the packet is normal or special.
3860 * Implemented the unidirectional MAC keys. Affected files
3861 lib/silcske/silcske.c, silcd/protocol.c and
3862 lib/silcclient/protocol.c.
3864 * Implemented the packet sequence number to the MAC computation.
3865 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3866 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3867 lib/silcclient/protocol.c.
3869 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3871 * Allow backup router to announce servers. All servers
3872 announced by backup router are added to the global list
3873 automatically. Update hte server's socket to our primary
3874 router also when backup router announces a server.
3875 Affected file silcd/packet_receive.c.
3877 * Do not update the client->router in the function
3878 silc_server_udpate_clients_by_server if the client is on
3879 global list. We might fail to find any specific server
3880 for locally connected clients and local cell clients. They
3881 should still use the `from' and not `to' as client->router.
3882 This fixes backup router resuming protocol. Affected file
3883 silcd/server_util.c.
3885 * Decrease channel statistics count only if the channel
3886 deletion worked. Affected files are silcd/server.c and
3887 silcd/server_util.c.
3889 * Added silc_server_update_servers_by_server to update origin
3890 of all server entries. Used during backup router protocol.
3891 Affected files silcd/server_util.[ch], silcd/server.c. and
3892 silcd/backup_router.c.
3894 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3895 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3896 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3897 lib/silccrypt/silchmac.c.
3899 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3901 * Assure that router cannot reroute the same channel message
3902 to the sender. Affected file silcd/packet_receive.c.
3904 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3906 * Made better checks that the channel message is not sent
3907 to the router it came from. Affected file is
3908 silcd/packet_send.c. Fixed memory leak too.
3910 * Announce informations for incoming router connection, but
3911 only after checking if it is replaced by backup router.
3912 Affected file silcd/packet_receive.c.
3914 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3916 * Fixed the backup resuming protocol to work in multiple
3917 router environment. Affected file silcd/server_backup.c.
3919 * Route packet only to one router in the function
3920 silc_server_packet_send_to_channel. Affected file is
3921 silcd/packet_send.c.
3923 * Fixed silc_server_send_notify_dest to set the broadcast
3924 flag. Fixed the silc_server_send_notify_topic to actually
3925 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3926 Affected file silcd/packet_send.c.
3928 * Changed the SFTP Filesystem interface. Changed the
3929 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3930 the filesystem operation function. The SilcSFTPFilesystem
3931 is now a context that is allocated by all filesystem allocation
3932 functions and it already includes the operations structure
3933 and filesystem specific context. It is given as argument
3934 now to the silc_sftp_server_start. This made the interface
3935 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3936 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3938 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3940 * Changed the backup router adding and getting interfaces
3941 in the server. The router that will be replaced by the
3942 specified backup router is now sent as argument. Affected
3943 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3946 * Added silc_net_addr2bin_ne to return the binary form of
3947 the IP address in network byte order. Affected files
3948 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3950 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3952 * Check for existing server ID in silc_server_new_server
3953 and in silc_server_connect_to_router_final and remove the
3954 old entry if it exists. Affected file silcd/packet_receive.c,
3957 * Send the channel message always to only one router, either
3958 in upstream or downstream. Affected file is
3959 silcd/packet_send.c.
3961 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3963 * Wrote the definition of the backup resuming protocol to the
3964 protocol specification.
3966 * Removed one redundant channel key generation from normal
3967 server during joining procedure. Removed one redundant
3968 channel key sending from server to router during joining
3969 procedure. Affected file silcd/command.c.
3971 * Made minor bugfixes to the backup router resuming protocol.
3972 Affected file silcd/server_backup.c, server.c.

3977 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3980 * Implemented the backup resuming protocol that is used to
3981 resume the primary router position in the cell after the
3982 primary router comes back online. Affected files
3983 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3984 and silcd/server_util.[ch].
3986 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3988 * Sleep two (2) seconds after sending QUIT command to server.
3989 Affected file lib/silcclient/command.c.
3991 * Assure that if outgoing data buffer is pending do not force
3992 send any data. Affected file silcd/packet_send.c.
3994 * Assure that if outgoing data buffer is pending do not force
3995 send any data. Affected file lib/silcclient/client.c.
3997 * Implemented the backup router support when the primary router
3998 goes down. The servers and routers can now use the backup
3999 router as new primary router without loosing connectivity.
4001 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4003 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
4004 in the server to indicate disabled entry. All data read
4005 from the connection will be ignored and no data is sent
4006 for entry that is disabled. Affected files are
4007 silcd/idlist.h, silcd/server.c.
4009 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4011 * Created SFTP client and server test programs in the
4012 lib/silcsftp/tests directory.
4014 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4016 * Implemented memory filesystem (virtual filesystem) for
4017 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
4020 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4022 * Implemented the SFTP (SSH File Transfer Protocol) to the
4023 lib/silcsftp. It includes SFTP client and SFTP server
4026 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4028 * Moved lib/silccore/silcprotocol.[ch] to the
4029 lib/silcutil library.
4031 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
4032 take variable argument list pointer as argument. Affected
4033 file lib/silcutil/silcbuffmt.[ch].
4035 * Added silc_buffer_set function that is used to set data
4036 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
4037 Affected file lib/silcutil/silcbuffer.h.
4039 * Changed various routines in the core library to use the new
4040 silc_buffer_set instead of allocating new buffer only for
4043 * Added 64-bit value formatting and unformatting support to the
4044 silc_buffer_[un]format routines. Affected file is
4045 lib/silcutil/silcbuffmt.[ch].
4047 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
4048 to includes/bitmove.h.
4050 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4052 * Fixed channel user mode saving in client library. Affected
4053 file lib/silcclient/command[_reply].c.
4055 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4057 * Defined the file transfer to the SILC Protocol. Added
4058 new packet type SILC_PACKET_FTP and defined File Transfer
4059 Payload. The mandatory file transfer protocol is SFTP
4060 (SSH File Transfer Protocol). Affected file in addition
4061 of the internet draft is lib/silccore/silcpacket.h.
4063 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
4064 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
4065 is used as part of backup router protocol when the primary
4066 router of the cell is back online and wishes to resume
4067 the position as primary router.
4069 * Redefined the MAC generation keys in the protocol. The
4070 same key is not used anymore in both direction. Both
4071 direction will now use different keys for sending and
4072 receiving. This fixes a potential security flaw. This
4073 change causes incompatibilities in the protocol.
4075 * Redefined also the MAC computation from the packet.
4076 An packet sequence number is now added to the MAC
4077 computation. This prevents possible replay attacks against
4078 the protocol. This change too causes incompatibilities
4081 Added `sequence' field to the SilcPacketContext to hold
4082 the current sequence number for the packet.
4084 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4086 * Added `created' field to the SilcIDListData in the file
4087 silcd/idlist.h to indicate the time when the entry was
4090 * Added `created' field to the SilcChannelEntry too. Affected
4091 file silcd/idlist.h.
4093 * Added `creation_time' aguments to all the announcement functions
4094 in the server. If it is provided then only the entries that
4095 was created after the provided time frame are actually
4096 announced. Affected file silcd/server.[ch].
4098 * The protocol says that the Channel ID's IP address must be
4099 based on the router's IP address. Added check for this in
4100 the silc_server_new_channel when processing incoming New Channel
4101 Payload. Affected file silcd/packet_receive.c.
4103 * Print out the correct version with --version in SILC client.
4104 Affected file irssi/src/silc/core/silc-core.c.
4106 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4108 * Fixed WHOWAS command to check for completnes of the client
4109 entry always, not just when the command is coming from client.
4110 Affected file silcd/command.c.
4112 * Added new function silc_server_packet_queue_purge to purge the
4113 outgoing data queue to the network. After the function returns
4114 it is guaranteed that the outgoing packet queue is empty.
4115 Affected file silcd/packet_send.[ch].
4117 * Purge the outgoing packet queue in the rekey protocol's final
4118 callback to assure that all rekey packets go to the network
4119 before quitting the protocol. Affected file silcd/server.c.
4121 * Added silc_client_packet_queue_parse as similar function as
4122 in server to the client library. The affected file is
4123 lib/silcclient/client.c.
4125 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4127 * Splitted silcd/server.c and created silcd/server_util.[ch]
4128 for utility functions.
4130 * Added new socket flag SILC_SF_DISABLED to indicate that the
4131 connection is open but nothing can be sent to or received from
4132 the connection. Affected file lib/silcutil/silsockconn.[ch].
4133 The checking for disabled socket is checked in the low level
4134 silc_socket_write and silc_socket_read functions.
4136 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4138 * Allow only nicknames and channel names that fits into the
4139 7-bit unsigned char ASCII set. Affected file silcd/command.c.
4141 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4143 * When processing JOIN command reply in server check that if
4144 the channel exists in our global list we'll move it the local
4145 list. Affected file silcd/command_reply.c.
4147 * Fixed the check whether client is joined on the channel already
4148 in JOIN command. Affected file lib/silcclient/command.c.
4150 * Fixed the JOIN command reply to check whether the channel
4151 already exists. Affected file lib/silcclient/command_reply.c.
4153 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4155 * Added silc_ske_status_string to map the SKE error numbers
4156 to readable strings. The affected files are
4157 lib/silcske/silcske[_status].[ch].
4159 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4161 * Do not show the private channels on the WHOIS channel list
4162 as it is not allowed by the protocol. The affected file is
4165 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4167 * Assure that the packet length digged from the actual packet
4168 is something sensible in the silc_packet_decrypt_rest_special
4169 in lib/silccrypt/silcpacket.c.
4171 * Free and NULL the allocated pointer in silc_hmac_alloc if
4172 the HMAC allocation fails. The affected file is
4173 lib/silccrypt/silchmac.c.
4175 * Print the selected security properties to the log files in
4176 the server. Affected file silcd/protocol.c.
4178 * Add SKE's reference counter even if calling the completion
4179 callback manually. Otherwise it goes negative, although it
4180 does not cause any problems. The affected file is
4181 lib/silcske/silcske.c.
4183 * Remove the client entry with short timeout after giving the
4184 KILL command. Affected file lib/silcclient/command.c.
4186 * Fixed to send error reply in WHOIS and IDENTIFY commands in
4187 case all found clients are already disconnected (WHOWAS would
4188 found them) in the server. Affected file silcd/command.c.
4190 * Update the last_receive (time of last data received) to be
4191 updated only when received private or channel message so that
4192 the idle time showed in WHOIS makes more sense.
4194 * Added boolean field `valid' in to the SilcClientEntry in the
4195 client library to indicate whether the entry is valid or not.
4196 This fixes the nickname change bug on channel when changing
4197 the nickname to be same than the old (like nick to Nick) the
4198 nickname formatter doesn't set the new nick anymore to Nick@host.
4199 Affected file lib/silcclient/idlist.[ch].
4201 * Now actually fixed the nickname changing on disconnection.
4202 Added new function silc_change_nick to the Irssi SILC Client.
4203 Affected file irssi/src/silc/core/client_ops.c,
4204 irssi/src/silc/core/silc-nicklist.[ch].
4206 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4208 * Check that the public key exists in the GETKEY command before
4209 trying to encode it. Affected file silcd/command.c.
4211 * Print some notifications on received public keys with GETKEY
4212 command in the Irssi SILC Client. Affected files are
4213 irssi/src/fe-common/silc/module-formats.[ch],
4214 irssi/src/silc/core/client_ops.c.
4216 * Use IDENTIFY command to resolve the server information in the
4217 GETKEY command instead of INFO command. Affected file
4218 lib/silcclient/command.c.
4220 * All command reply functions in the client library now calls
4221 the pending command reply callbacks even if an error has
4222 occurred. The server has done this a long time and now it was
4223 time to move the client library to this as well. Now all
4224 errors can be delivered back to the pending command reply
4225 callbacks if necessary. Affected files are
4226 lib/silcclient/command[_reply].[ch].
4228 * Change the nickname on disconnection back to the username
4229 because in reconnect the server will enforce it to it anyway.
4230 Affected file irssi/src/silc/core/silc-servers.c.
4232 * Fixed a config file parsing bug in the Irssi SILC client.
4233 Affected file irssi/src/silc/core/clientconfig.c.
4235 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4237 * When printing the channel mode on JOIN, verify that the
4238 channel key and channel's HMAC are valid. Affected file
4239 irssi/src/silc/core/client_ops.c.
4241 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4243 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
4244 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
4245 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
4247 * Removed channel key rekey task deleting from the function
4248 silc_server_save_channel_key. Affected file silcd/server.c.
4249 Added explicit timeout task context instead that is used to
4250 delete the task if we are registering a new task before the
4251 new task has elapsed.
4253 * When channel key rekey occurs the client library now saves
4254 the old channel key for a short period of time (10 seconds) and
4255 is able to use it in case some is still sending channel
4256 messages encrypted with the old key after the rekey. Affected
4257 file lib/silcclient/[idlist.h|client_channel.c].
4259 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4261 * Added check to the silc_server_new_id_real to not accept
4262 new ID if it is the sender's own ID. Affected file is
4263 silcd/packet_receive.c.
4265 * Assure that we do not announce ourself or the one we've
4266 sending our announcements when we're router and are announcing
4267 servers to our primary router. Affected file silcd/server.c.
4269 * Fixed silc_server_command_identify_check_client to assemble
4270 correct WHOIS packet. It send corrupted WHOIS packet and
4271 caused problem with router to router connections. Affected
4272 file silcd/command.c.
4274 Fixed also silc_server_command_whois_check the same way
4275 as for the IDENTIFY command.
4277 * Added new SilcIDListStatus to the server in the SilcIDListData
4278 structure. The status now includes the current status of
4279 the entry (like registered, resolved etc.). Affected file
4280 silcd/idlist.[ch]. Defined a bunch of different status types
4281 as well. This replaced the old boolean registered field as well.
4283 Added resolve_cmd_ident field to the SilcClientEntry structure
4284 too so that if the entry is for example being resolved so
4285 another command may attach to the same pending command reply
4286 without requiring to resolve the same entry again. This concept
4287 should optimize the WHOIS and the IDENTIFY resolving under
4288 heavy load by taking away unnecessary resolving for entries
4289 that are being resolved already.
4291 Added support for adding multiple pending commands for one
4292 command idenfier. Affected file silcd/command[_reply].[ch].
4294 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4295 before deleting the data. Otherwise the hash table will have
4296 freed data in comparison functions. Affected file is
4297 silcd/command_reply.c.
4299 * Fixed silc_idlist_replace_client_id to add the new entry to
4300 the cache with NULL nickname. Otherwise there will be invalid
4301 memory as the nickname after the nickname is freed. Affected
4302 file silcd/packet_receive.c.
4304 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4305 saved into wrong slots because the previous number of entries
4306 was not taken into account. Affected file silcd/idlist.c.
4307 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4309 * If we are router and we receive JOIN notify to a channel that
4310 does not have any users then notified client is marked as the
4311 channel founder, as it is it. The affected file is
4312 silcd/packet_receive.c
4314 * Added to the extended hash table API's table_del_*ext functions
4315 the destructor as argument too, so that the caller can decide
4316 which destructor to use or whether to use destructor at all.
4317 Affected file lib/silcutil/silchashtable.[ch].
4319 * Fixed ID Cache purging. It actually deleted the entries from
4320 the hash table after the data was freed. The hash table ended
4321 up comparing freed memory. The affected file is
4322 lib/silccore/silcidcache.c.
4324 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4326 * Fixed Irssi SILC client's KILL command's HELP syntax.
4328 * The USERS command now resolves the detailed user information
4329 if the userinfo field is missing. Affected file is
4330 lib/silcclient/command_reply.c.
4332 * Do not print error in silc_file_read if the read file does
4333 not exist. Just silently return NULL. Affected file is
4334 lib/silcutil/silcutil.c.
4336 * Fixed the silc_log_output to not wine about NULL filename
4337 and to not create some bogus " " filename. Affected file is
4338 lib/silcutil/silclog.c.
4340 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4342 * Fixed various printing bugs on the user interface in the
4343 Irssi SILC Client. Minor changes that were forgotten from
4346 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4348 * Fixed the configure.in.pre and the compilation and distribution
4349 environment to support the new autoconf 2.52. That version is
4350 now required to compile the CVS trunk.
4352 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4354 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4355 to generally parse user@fqdn format strings. Affected file
4356 lib/silcutil/silcutil.c.
4358 * Added nickname_format and nickname_force_format fields to the
4359 SilcClientParams structure. The first one defines the format
4360 for the nicknames that the library will enforce if the receives
4361 multiple same nicknames. The second one is boolean value and
4362 can be used to force the library to always enforce the format
4363 to the nicknames regardles whether there are multiple nicknames
4364 or not. This configurable formatting was employed to flexibly
4365 support accessing multiple nicknames from the user interface.
4366 The userinterface can now set the nicknames to what ever format
4367 they prefer. Affected file lib/silcclient/silcapi.h.
4369 Added function silc_client_nickname_format to the file
4370 lib/silcclient/idlist.c. It performs the nickname formatting.
4372 Added new field `hostname´ to the SilcClientEntry context.
4373 It holds the hostname of the client. Affected file is
4374 lib/silcclient/idlist.h.
4376 * Irssi SILC Client sets the nicknames in nick@hostn format.
4377 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4378 irssi/src/silc/core/silc-core.c.
4380 The WHOIS printing now also shows both the real nickname and
4381 the formatted nickname so that user knows how to access the
4382 user if there are multiple same nicknames cached. Affected
4383 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4384 printing formatting too to take the hostname now as a separate
4385 argument. The Affected file is
4386 irssi/src/fe-common/silc/modules-formats.[ch].
4388 * Changed the silc_client_get_clients_local to accept the formatted
4389 nickname as argument. It accepts the real nickname too but the
4390 formatted nickname can be used to find the true entry from
4391 multiple entries. Affected file lib/silcclient/silcapi.h and
4392 lib/silcclient/idlist.c.
4394 * Added nickname_format_parse field to the SilcClientParams.
4395 It is a callback function provided by the application to parse
4396 the nickname out of the formatted nickname string. The library
4397 calls it to get the nickname from the formatted string. Since
4398 the application generally knows better the format of the nickname
4399 string it parses it instead of the library, even though library
4400 encodes the formatted string. If the callback function is not
4401 provided then the library will use the string as is. The
4402 affected file is lib/silcclient/silcapi.h.
4404 * All the nickname strings passed to the client library in
4405 commands are now expected to be formatted nickname strings.
4406 If the command does not support the formatted nickname string
4407 it will assume that the sent string is the actual nickname.
4408 Affected file lib/silcclient/command.c.
4410 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4412 * Added public key authentication support to OPER and SILCOPER
4413 commands in the client library. Affected file is
4414 lib/silcclient/command.c.
4416 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4418 * Changed the get_auth_methdod client operation to be asynchronous.
4419 It can be async if the application resolves the authentication
4420 method from the server during the negotiation. Added new
4421 SilcGetAuthMeth completion callback that the application will
4422 call after resolving the authentication method.
4424 Added function silc_client_request_authentication_method that
4425 the application can use to resolve the authentication method
4426 from the server. Added also SilcConnectionAuthRequest callback
4427 that the library will call after the server has replied. The
4428 application can call this function if it does not know the
4429 current authentication method.
4431 Affected files are lib/silcclient/client.c and
4432 lib/silcclient/silcapi.h.
4434 * The Irssi SILC client now automatically resolves the authentication
4435 method incase any configuration information is not present (and
4436 currently there never is). The affected file is
4437 irssi/src/silc/core/client_ops.c.
4439 * Fixed public key authentication from the client library.
4440 Affected file lib/silcclient/protocol.c. Changed also the
4441 protocol specification about the public key authentication in
4442 the connection authentication protocol. The actual data to be
4443 signed is now computed with a hash function before signing.
4445 * Fixed the public key authentication from the server as well.
4446 Affected file silcd/protocol.c.
4448 * Removed the mlock()'s from the memory allocation routines.
4449 Affected file lib/silcutil/silcmemory.c. The ./configure does
4450 not check anymore for the mlock(). Affected file is
4453 * Fixed USERS command in server to allow the execution of the
4454 command for private and secret channels if the client sending
4455 the command is on the channel. Affected file silcd/command.c.
4457 * Fixed silc_client_get_clients_local to return the clients
4458 count correctly. It could return wrong value. Affected file
4459 lib/silcclient/idlist.c.
4461 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4463 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4464 types. The assembler optimizations seemed not to like 64-bit
4465 data types. The assmebler optimizations thus are now enabled
4466 also for BSD systems as opposed to only enable them for Linux.
4468 * Do not check for threads at all on BSD systems. Affected
4469 file configure.in.pre.
4471 * Removed -n and -h options from the Irssi SILC Client since
4472 they are not used in silc.
4474 * Fixed the prime generation to assure that the first digit
4475 of the generated random number is not zero since our conversion
4476 routines does not like number strings that starts with zero
4477 digit. If zero digit is seen the random number is regenerated.
4478 This caused some corrupted RSA keys when the zero first digit
4479 was met. Affected file lib/silcmath/silcprimegen.c.
4481 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4483 * Fixed WIN32 configuration in the ./configure script.
4484 Fixed to include xti.h on environments that has it.
4485 Patches by Carsten Ilchmann and andrew.
4487 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4489 * Changed the silc_id_create_client_id to be collision
4490 resistant. It is now assured that there cannot be created
4491 two same client ID's. I suspect that some weird bugs in
4492 the server were actually caused by duplicate Client IDs.
4493 Affected file silcd/serverid.[ch]. A router receiving
4494 new ID now also assures and informs the sending server
4495 if the ID caused collision.
4497 * Changed the silc_id_create_channel_id to also assure that
4498 there are no collisions.
4500 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4502 * Statement about ignoring the Mutual Authentication flag when
4503 performing rekey with PFS was a bit misleading. It is ignored
4504 if it was set in the initial negotiation, it cannot be even
4505 set in the rekey. Fixed in the ke-auth draft. Started the
4506 new versions of the protocol drafts in the doc/.
4508 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4510 * Fixed a bug in silc_client_command_identify_save when saving
4511 new channel information. The channel name was no duplicated
4512 and caused crash on exit. Affected file is
4513 lib/silcclient/command_reply.c.
4515 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4517 * Fixed the getkey command handling in the server. Send just
4518 empty OK reply to the sender if the key could not be fetched
4519 (but everything else was ok, like the key just was not available).
4520 Changed the public key parameter to optional in the protocol
4521 specs so that empty OK reply can be sent. Affected file
4524 Added a message to Irssi SILC client to tell to user if the
4525 server did not return a public key.
4527 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4529 * Fixed a channel key regeneration bug. It registered new
4530 timeout tasks exponentially until all system resources were
4531 used. Affected file silcd/server.c.
4533 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4535 * Added the SILC Document generator to the scripts/silcdoc.
4536 It can be used to generate the Toolkit Reference Manual out
4537 of the source tree. Internally it will also use the RoboDoc
4538 generator now imported in util/robodoc.
4540 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4542 * Added couple of return's in rekey protocol if error orccurred
4543 during the protocol. The execution must be terminated.
4544 Affected file silcd/protocol.c. Also, terminate the protocol
4545 always with timeout.
4547 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4549 * The client's Client ID was created initally from the wrong
4550 nickname (it could have been in format nick@host) in the
4551 silc_server_new_client. Affected file silcd/packet_receive.c
4553 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4555 * Added some SILC_LOG_ERROR's to various error conditions
4556 if client could not be added to ID cache. Affected files
4557 silcd/packet_receive.c and silcd/server.c.
4559 * When client's sock->user_data is freed, NULL also the
4560 client->router and client->connection pointers. Added check
4561 for these pointers being NULL to various places around the
4562 code. Affected file silcd/server.c.
4564 * Added client->data.registered == TRUE checks to various
4565 places around the code to assure that unregistered client's
4566 are not handled when it is not allowed. Affected file
4569 * Added `bool registered' fields to all
4570 silc_idlist_[server|client]_get_* routines to indicate whether
4571 the fetched client needs to be registered or not. Affected
4572 file silcd/idlist.[ch].
4574 * Add your own entry as registered to the ID cache in the
4575 server. Affected file server.c.
4577 * Fixed a bug in silc_server_new_server. The SilcServer was
4578 set as the new server's context instead of SilcServerEntry.
4579 This naturally caused some weird bugs.
4581 * Added "updated" field the SilcChannelEntry which indicates
4582 the time since the channel entry was last accessed. This
4583 can be used to determine whether it is necessary to
4584 announce the channel after backup resuming protocol.
4585 Affected files silcd/idlist.[ch].
4587 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4589 * Do not delete the channel rekey task when adding it
4590 for in silc_server_create_channel_key.
4592 * Changed the silc_server_create_channel_key to return
4593 TRUE or FALSE to indicate the success of the channel key
4596 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4598 * Fixed MSVC++ project files and added missing files to
4599 Makefiles under win32/.
4601 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4603 * Do not add TCP_NODELAY flag if the operating system
4604 does not have it defined. Affected files are
4605 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4607 * Fixed buffer overflow from Irssi SILC Client. Affected
4608 file irssi/src/fe-common/core/themes.c.
4610 * Fixed double free in client library in the file
4611 lib/silcclient/client.c when disconnecting from server.
4613 * Applied double free patch from cras to Irssi SILC client.
4614 Affected files irssi/src/core/[modules/expandos].c
4616 * Fixed the disconnection handling to Irssi SILC Client.
4617 The application must call silc_client_close_connection
4618 in ops->connect client operation in case of failure of
4619 the connection. Affected file is
4620 irssi/src/silc/core/client_ops.c.
4622 * Do not set sock->protocol to NULL in the function
4623 silc_client_close_connection after executing the protocol's
4624 final callback since the sock might not be valid anymore.
4625 Affected file lib/silcclient/client.c.
4627 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4629 * Do not enable SILC_THREADS if the linking with libpthread
4630 did not happen. Affected file configure.in.pre.
4632 * Added notion to protocol specification that server must
4633 verify the sent authentication payload with CMODE when
4634 setting the channel founder key. Implemented it to the
4635 server. Affected file silcd/command.c.
4637 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4639 * Added _EXTRA_DIST SILC distribution variable to the
4640 distributions file. It is used to conditionally add extra
4641 files or directories to the specific distribution. Affected
4642 files ./prepare, Makefile.am.pre and distributions.
4644 Removed the `_' from the start of the distribution names.
4647 * Added README.WIN32 for instructions to compile the Toolkit
4650 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4652 * Fixed a double free in disconnection in the server. Affected
4653 file is silcd/server.c.
4655 * Fixed the lib/silcske/groups.c to work now also with GMP
4656 MP library. The string conversion did not work when using
4657 specific base and the base is indicated in the string as well.
4659 * Created win32/ directory which now includes MSVC++ specific
4660 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4661 It will appear only in the toolkit distribution
4663 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4665 * Changed the key material distribution function in case when
4666 the hash output is too short. The data is now concatenated
4667 a bit differently than it used to. Made the change to the
4668 SKE protocol specification.
4670 * Added better GMP detection to configure.in.pre. A patch
4673 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4675 * Fixed a minor bug in SKE that might cause some problem on
4676 some platforms. Affected file lib/silcske/silcske.c.
4678 * Added the cookie checking for initiator in the SKE. It checks
4679 that the responder returns the sent cookie unmodified. The
4680 affected file is lib/silcske/silcske.c. Added new SKE
4681 error type INVALID_COOKIE that can be sent during the
4682 negotiation. Fixed some memory leaks as well.
4684 * Added the "invalid cookie" error message to Irssi SILC client's
4687 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4689 * Added `task_max' field to the SilcClientParams to indicate
4690 the maximum tasks the scheduler can handle. If set to zero,
4691 default values are used. Affected file lib/silcclient/silcapi.h.
4693 * Fixed memory leaks in silc_client_close_connection. Affected
4694 file lib/silcclient/client.c.
4696 * Added silc_client_del_client_entry to client library to free
4697 all memory of given client entry. Affected file is
4698 lib/silcclient/idlist.[ch].
4700 * Added new functions silc_client_del_channel and
4701 silc_client_del_server to delete channel and server entries.
4702 Affected file lib/silcclient/[silcapi.h/idlist.c].
4704 * Removed silc_client_del_client_by_id from silcapi.h.
4706 * Fixed the INFO command to return the server's own info
4707 correctly when querying by Server ID. Affected file is
4710 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4712 * Removed the non-blocking settings in WIN32 code in the
4713 silc_sock_[read/write] and added SleepEx instead. Affected
4714 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4715 of input data is now checked with FIONREAD and ioctlsocket.
4717 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4719 * Call silc_schedule_task_del_by_context in the
4720 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4721 Affected file lib/silccore/silcprotocol.c.
4723 * Call silc_protocol_cancel for active protocols in the
4724 silc_server_close_connection if the funtion
4725 silc_server_free_sock_user_data has not been called.
4726 Affected file silcd/server.c.
4728 * Generic tasks cannot be deleted using the del_by_fd
4729 task deleting function since generic tasks does not match
4730 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4732 * Added a notion to SILCOPER help file that the SILCOPER works
4733 only on router server, not on normal server.
4735 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4737 * Added for WIN32 support for the new scheduler as well.
4738 Affected file lib/silcutil/win32/silcwin32schedule.c.
4740 * Fixed the SHA1 implementation to work on various platforms.
4742 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4744 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4745 API. It is part of the scheduler now. Everything else is
4746 as previously but some functions has changed their names.
4747 Checkout the lib/silcutil/silcschedule.h for the interface.
4748 Updated all applications to use the new interface. Affected
4749 files are lib/silcutil/silcschedule.[ch].
4751 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4753 * Found a bug in the SKE implementation. The HASH value,
4754 specified by the protocol, was not computed correctly. The
4755 public key of the responder was not added to the computation
4756 even though it is mandatory. Affected file lib/silcske/silcske.c.
4757 This unfortunately causes incompatibilities with older
4758 clients and servers.
4760 * Added WIN32 specific network init and uninit functions:
4761 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4762 the Winsock2. Affected file lib/silcutil/silcnet.h and
4763 lib/silcutil/win32/silcwin32net.c.
4765 * Set the socket always to nonblocking mode on WIN32 after
4766 reading data or writing data. Affected file is
4767 lib/silcutil/win32/silcwin32sockconn.c.
4769 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4771 * Fixed various compilation problems under WIN32. Affected
4772 files lib/silcutil/win32/silcwin32thread.c and
4773 lib/silcutil/win32/silcwin32schedule.c.
4775 * Removed all _internal.h #includes from public header
4776 files. Internal headers must never be included from
4779 Removed also the lib/silcske/payload_internal.h file.
4781 * All include files that may be needed (public and some others
4782 included by the public headers) by application developers are
4783 now copied to the ./includes directory. It does not copy any
4784 internal headers. Affected file Makefile.defines.pre and all
4785 Makefile.am's under lib/ and subdirs.
4787 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4789 * Do not change the ~/.silc directory's permissions automatically.
4790 Affected file irssi/src/silc/core/clientutil.c.
4792 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4794 * Do not cancel the protocol in silc_server_close_connection
4795 it might cause recursion. Now cancelled in the function
4796 silc_server_free_sock_user_data. Affected file silcd/server.c.
4798 * Fixed the silc_server_remove_clients_by_server to regenerate
4799 the channel keys correctly finally. Added also new function
4800 silc_server_remove_clients_channels to actually do it.
4801 Affected file silcd/server.c.
4803 * Fixed the silc_server_new_channel to not crash by giving
4804 wrong router to the new channel. Affected file is
4805 silcd/packet_receive.c.
4807 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4809 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4810 which is given as argument to the silc_client_alloc now.
4811 It can be used to configure the client and set various parameters
4812 that affect the function of the client.
4814 * The USERS command in server did not check whether the channel
4815 is private or secret. Affected file silcd/command.c.
4817 * Added new argument to the USERS command in protocol specification.
4818 The USERS command now can take the channel name as argument
4819 as well. Added support for this in client and server and
4820 updated the protocol specs.
4822 * Completed the GETKEY command in client. It can be now used
4823 to fetch also servers public key not only some clients.
4824 Affected files lib/silcclient/command[_reply].c.
4826 * Added silc_client_get_server to return server entry by the
4827 server name. Affected files lib/silcclient/silcapi.h and
4830 * Redefined the IDENTIFY command in protocol specification to be
4831 more generic. It now can be used to query information about
4832 any entity in the SILC Network, including clients, servers and
4833 channels. The query may be based either the entity's name
4834 or the ID. Added support for this in both client and server.
4836 Affected files silcd/command.c and lib/silcclient/command.c
4837 and command_reply.c.
4839 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4840 the _from_client and _from_server functions. Affected file
4843 * Added silc_client_get_channel_by_id_resolve to the file
4844 lib/silcclient/silcapi.h to resolve channel information by
4845 its ID. Added also silc_client_get_channel_by_id that
4846 does not resolve it from the server.
4848 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4850 * Added SilcServerEntry context into the client library
4851 to represent one server. The INFO command now allocates
4852 these to save the resolved server info. For now on the
4853 client library will also keep information about servers,
4854 connected and resolved with INFO.
4856 The INFO command now allocates the SilcServerEntry context
4857 and saves the server info there. The COMMAND_REPLY in
4858 the INFO now returns the parameters to application in
4859 same order as defined in the protocol specification.
4861 The entries are cached in the client->server_cache.
4863 * The INFO command is now issued after received the Client ID
4864 from the server. Affected file lib/silcclient/client.c.
4866 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4867 to the application as the mode changer might be server.
4868 It is guaranteed that NULL is not returned anymore to the
4869 application. Affected file lib/silcclient/client_notify.c.
4871 The ID Type is now also passed to the application so that
4872 it can check whether the returned entry is SilcClientEntry
4875 Added new function silc_client_get_server_by_id to return
4876 the server entry by ID. Affected files are the
4877 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4879 * Do not create the channel in the Irssi SILC Client when issuing
4880 the JOIN command but when received the sucessful JOIN command
4881 reply. Otherwise the channel might get created even though we
4882 could not join it. The Affected file is
4883 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4885 * Fixed a channel joining bug in router. The router must also
4886 check the channel modes, invite and ban lists etc. when serving
4887 the JOIN command sent by normal server. Affected file is
4888 silcd/command.c. The router now resolves the client's
4889 information from the server who sent the JOIN command if it
4890 does not know it, and processes the JOIN command only after
4893 * Changed the SilcCommandCb to take new argument; void *context2.
4894 Affected file lib/silccore/silccommand.h
4896 The second argument in the command callbacks in the server now
4897 includes the SilcServerCommandReplyContext if the command was
4898 called as pending command callback from the command reply.
4899 Otherwise it is NULL. When called as pending the status of the
4900 command reply will be checked and if it was erronous the
4901 error will be sent to the original sender of the command.
4902 This way the client always receives the error messages even
4903 though the server was actually the one who received the error
4904 when it resent the command to router, for example. Affected
4905 files silcd/command[_reply].[ch].
4907 * Fixed sending WHOWAS command's error message to client if
4908 the requested client could not be found. It was missing.
4911 * Changed the CMODE and CUMODE commands reply arguments in the
4912 protocol specification. The Channel ID is now sent in both
4913 of the commands to identify the channel. Implemented this
4914 new feature to the client and server. Affected files
4915 lib/silcclient/command_reply.c and silcd/command.c.
4917 * Made better checks for invite and ban lists in the JOIN
4918 command in server. Affected file silcd/command.c.
4920 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4922 * The server now performs the incoming host IP/DNS lookup
4923 using the silc_socket_host_lookup and thus does not block
4924 the server anymore. Affected file silcd/server.c.
4926 * Completed the multi-thread support for SILC Scheduler in
4927 the lib/silcutil/silcschedule.c.
4929 * Fixed the configure.in.pre to detect the pthread correctly
4932 * Fixed a deadlock in silc_task_queue_wakeup in the file
4933 lib/silcutil/silctask.c.
4935 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4937 * Added new function silc_schedule_wakeup that is used in
4938 multi-threaded environment to wakeup the main thread's
4939 schduler. It needs to be used when a thread adds a new task
4940 or removes a task from task queues. After waking up, the
4941 scheduler will detect the task queue changes. If threads
4942 support is not compiled in this function has no effect.
4943 Implemented the wakeup mechanism to both Unix and WIN32
4944 systems. Affected files are lib/silcutil/silcschedule.[ch],
4945 lib/silcutil/unix/silcunixschedule.c and the
4946 lib/silcutil/win32/silcwin32schedule.c.
4948 * Added new function silc_task_queue_wakeup to wakeup the
4949 scheduler by the specified task queue. Affected file
4950 lib/silcutil/silctask.[ch].
4952 * The silc_socket_host_lookup_start now wakes up the scheduler
4953 after adding the timeout task. Affected file is
4954 lib/silcutil/silcsockconn.c.
4956 * The silc_socket_host_lookup is synchronous now if the threads
4957 support is not compiled in. However, the callback is still
4958 called asyncronously through the scheduler, anyway. Affected
4959 file lib/silcutil/silcsockconn.c.
4961 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4963 * Added new function silc_socket_host_lookup to perform
4964 asynchronous IP and FQDN lookups for the socket connection.
4965 Affected files lib/silcutil/silcsockconn.[ch].
4967 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4969 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4970 that may or may not compile the mutex support in.
4972 Changed the silc_mutex_alloc interface. It allocates the
4973 mutex now to the sent pointer and returns TRUE or FALSE.
4975 Affected file lib/silcutil/silcmutex.h.
4977 * Wrote the SILC Task Queue interface to support multi-threads.
4978 Affected file lib/silcutil/silctask.[ch].
4980 * Wrote the SILC Scheduler to support multi-threads. Affected
4981 file lib/silcutil/silcschedule.c.
4983 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4985 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4986 in lib/silcutil/win32/.
4988 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4990 * Defined SILC Mutex API and SILC Thread API and implemented
4991 them for Unix. Affected files are
4992 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4993 lib/silcutil/unix/silcunixmutex.c and
4994 lib/silcutil/unix/silcunixthread.c.
4996 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4998 * Fixed the silc_server_remove_clients_by_server's channel
4999 key re-generation. The hash table handling was incorrect
5000 and would not work with many channels. Affected file is
5003 * Fixed some memory leaks around the server code.
5005 * Rewrote the silc_server_get_users_on_channel to support IPv6
5006 based Client ID's. Affected file silcd/server.c.
5008 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
5009 specification. However, a separate document must be written
5010 to define the detailed signing procedure and the payload
5011 associated with the flag. Defined the flag to the
5012 lib/silccore/silcchannel.h as well.
5014 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5016 * Changed the dynamic tables to static size tables in the
5017 lib/silccrypt/silchmac.c.
5019 * Removed GCC dependencies from the code. A patch by cras.
5021 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5023 * Do not show the error "Error receiving packet bla bla"
5024 in server if it really was not an error (-2 means that reading
5025 is pending). Affected file silcd/server.c.
5027 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5029 * Fixed a possible crash in silc_server_remove_clients_by_server
5030 in silcd/server.c. Fixed there also some memory leaks.
5032 * Fixed the silc_idlist_replace_client_id. It could replace
5033 wrong key in the hash table. Affected file silcd/idlist.c.
5035 * Do not check whether there are global users on the channel
5036 if the channel->global_users is FALSE. Affected functions
5037 silc_server_remove_from_one_channel and
5038 silc_server_remove_from_channels in silcd/server.c. Also,
5039 do not check if the removed client is local as we can be
5040 sure that global client was not removed from the channel
5041 and checking for global users is not needed.
5043 * The silc_server_remove_clients_by_server now re-generates
5044 the channel keys correctly for those channels that had
5045 clients removed from them. Affected file silcd/server.c.
5047 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5049 * Found the reason of random crashes in the server. We weren't
5050 ignoring the SIGPIPE signal (which can be sent in write())
5051 and it crashed the server. Affected file silcd/silcd.c.
5053 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5055 * Assure that sock->user_data is not NULL in the function
5056 silc_server_packet_send in silcd/packet_send.c.
5058 * Disconnect the remote connection if it could not be added
5059 to any ID lists in the server. The affected file is
5062 * Check in silc_server_packet_send[_real/dest] that the
5063 socket is not disconnecting and ignore the data if it is.
5064 Affected file silcd/packet_send.c.
5066 * Define inline to __inline on native WIN32 compilation.
5067 Affected file includes/silcwin32.h.
5069 * Added some explicit type casts for inline code since MSVC
5070 require them. Affected files lib/silcutil/silcbuffer.h,
5071 lib/trq/silcdlist.h and lib/trq/silclist.h.
5073 * Print warning in log files from now on if the packet
5074 decryption fails. Affected file silcd/server.c.
5076 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5078 * Changed the `say' client operation's interface to accept
5079 new `type' argument to indicate the type of the message sent
5080 by the library. The application may filter the library's
5081 messages according the type. The affected file is the
5082 lib/silcclient/silcapi.h.
5084 * Added two new functions to lib/silcclient/silcapi.h:
5085 silc_client_del_client and silc_client_del_client_by_id.
5086 Affected file lib/silcclient/idlist.c.
5088 * Moved the clientincludes.h from includes/ to silc/ and
5089 serverincludes.h from includes/ to silcd/.
5091 * The modes for the CMODE and CUMODE are now passed as
5092 uint32 for application with COMMAND_REPLY. The affected
5093 file is lib/silcclient/command_reply.c.
5095 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5097 * /WHOIS without arguments shows client's own information.
5098 Affected file lib/silcclient/command.c.
5100 * Changed PING to not accept any arguments. The specs
5101 says that client can ping only the connected server so
5102 requiring an argument is not needed. Affected file is
5103 lib/silcclient/command.c.
5105 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5107 * Fixed a fatal bug in private message sending and reception
5108 encryption and decryption when using private message keys.
5109 The implementation was incorrect and did not follow the
5110 specification. It causd that some of the message were
5111 lost since it did not use the sending and receiving keys
5112 as the protocol suggests. This has been fixed and will cause
5113 incompatibilities with older clients when sending private
5114 message encrypted with private message keys. Affected files
5115 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
5116 and various other in Irssi SILC Client.
5118 Added `responder' boolean argument to the functions
5119 silc_client_add_private_message_key[_ske] to indicate when
5120 the key is added as responder or initiator of the key
5123 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5125 * Removed the silc_ske_check_version function and created
5126 a SilcSKECheckVersion callback. Added also a function
5127 silc_ske_set_callbacks that is now used to set all SKE
5128 callbacks. The callback functions are not given to
5129 the SKE functions anymore, but this function is used to
5132 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
5134 * Added `silc_version' argument to the silc_client_alloc
5135 to define the version of the application for the library.
5136 The library will use the version string to compare it
5137 against the remote host's (usually a server) version
5138 string. Affected file lib/silcclient/silcapi.h
5140 * Added the KE protocol context to Key Agreement context
5141 in client library so that we can abort the SKE if it
5142 is in process when we get timeout. Affected file is
5143 lib/silcclient/client_keyagr.c.
5145 * Do not resolve the client ID forever if it returns in the
5146 first time that such client does not exist. This was done
5147 for example with private message. Affected file is
5148 lib/silcclient/client_prvmsg.c.
5150 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5152 * Do not add regex.h for WIN32. The affected file
5153 includes/silcincludes.h.
5155 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
5156 not work yet 100%. It generates the DLL's automatically
5157 when compiling with --with-win32 under cygwin.
5159 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5161 * lib/contrib/regex.c is not compiled on WIN32.
5163 * Added silc_net_get_socket_opt function to the
5164 lib/silcutil/silcnet.h.
5166 * Added includes/silcwin32.h for WIN32 specific includes
5169 * Do not use ptime structure or any of the posix process
5170 functions on WIN32 in lib/silccrypt/silrng.c.
5172 * Added silc_gettimeofday to provide generic function
5173 for struct timeval on all platforms. Added the function
5174 to lib/silcutil/silcutil.h.
5176 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5178 * Moved the lib/silccore/silcsockconn.[ch] to the utility
5179 library as they clearly belong there. As a plus side we
5180 can make the actual socket connection routines platform
5183 Added also new generic function silc_socket_read and
5184 silc_socket_write (that used to be silc_packet_[read/write].
5185 The implementation of these are platform specific.
5187 * Added WIN32 specific routines of silc_socket_[read/write]
5188 to lib/silcutil/win32/silcwin32sockconn.c.
5190 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5192 * Added preliminary support for native WIN32 compilation under
5193 cygwin (using the -mno-cygwin option for GCC) to the
5194 ./configure.in.pre. The --with-win32 now prepares the
5195 compilation for native WIN32.
5197 * Rewrote the SILC Scheduler interface in the file
5198 lib/silcutil/silcschedule.h. The scheduler is now context
5199 based and does not have anymore any global static scheduler.
5200 Moved the Unix scheduler to the lib/silcutil/unix/ directory
5201 and created lib/silcutil/win32 directory for WIN32 based
5204 * Added Unix specific network routines to the
5205 lib/silcutil/unix/silcunixnet.c and the old
5206 lib/silcutil/silcnet.c includes now only generic routines.
5208 Added WIN32 specific network routines to the
5209 lib/silcutil/win32/silcwin32net.c.
5211 * Added Unix specific utility functions from the
5212 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
5214 * Added WIN32 SILC Scheduler to the file
5215 lib/silcutil/win32/silcwin32schedule.c. The code is of course
5218 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5220 * Do not handle JOIN notify in the server if the target client
5221 is not registered (idata->registered == FALSE). The affected
5222 file is silcd/packet_receive.c.
5224 * Update the nickrec->founder in event_cumode in the Irssi SILC
5225 client. Affected file irssi/src/silc/core/silc-channels.c.
5227 * Fixed the CUMODE_CHANGE notify handling in the server when
5228 server and router are announcing their clients on channels.
5229 Now the mode changes are saved and notified correctly. The
5230 affected file is /silcd/packet_receive.c.
5232 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
5233 They really did not replace the cache entry in the ID Cache.
5234 Now they do that. Affected file silcd/idlist.c.
5236 * Fixed the KICK notify handling in the Irssi SILC client to
5237 update the channel records so that the kicked client does not
5238 appear to be on the channel. The affected file is
5239 irssi/src/silc/core/silc-channels.c.
5241 * Always update the conn->current_channel when executing command
5242 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
5244 * Fixed the KILL notify handling in Irssi SILC client to remove
5245 the killed client on all channels.
5247 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5249 * Fixed the silc_parse_command_line to remove extra spaces
5250 from the start and end of the arguments. Affected file is
5251 lib/silcutil/silcutil.c.
5253 * Cancel and free any active protocol in the function
5254 silc_server_close_connection. Affected file silcd/server.c.
5256 * Cancel and free any active protocol in the function
5257 silc_client_close_connction. Affected file is
5258 lib/silcclient/client.c.
5260 * Do not execute the KILL command for clients that are in
5261 history (ie. they are not in the network). Affected file is
5264 * Fixed KILL notify handling, client does not crash anymore.
5265 Affected file irssi/src/silc/core/silc-channels.c.
5267 * Reduced the default packet buffer size from 2048 to 1024 in
5268 lib/silccore/silcpacket.c.
5270 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5271 counter to the SKE context that is incresed when the SKE library
5272 performs async operation outside the library. If the outside
5273 process frees the SKE context and FREED status will be set
5274 and the library will detect after the sync operation that the
5275 libary is freed. The affected files are
5276 lib/silcske/silcske[_status].[ch].
5278 * Resolve the client entry information in the function
5279 silc_client_channel_message to assure that NULL pointer is not
5280 passed as client entry to the application. */
5282 * Fixed the task timeout calculation to assure that there is
5283 never negative timeouts. The affected file is
5284 lib/silcutil/silcschedule.c.
5286 * Fixed the channel user mode notification sending in server.
5287 It was sent point-to-point to the router (or to server by router)
5288 but it needs to be destined to a channel. The routines now
5289 supports sending the channel user mode notifys to the channels
5290 when announcing clients and channels. Affected files are
5291 silcd/server.c and silcd/packet_receive.c.
5293 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5294 It did not actually replace the old channel entry in the cache.
5295 Affected file lib/silcclient/client_notify.c.
5297 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5299 * Fixed a possible crash in silc_packet_send_prepare. It now
5300 assures always that there is enough space in the buffer and
5301 at the tail area of the buffer (for MAC).
5303 Fixed the inbound buffer reallocation in silc_packet_read.
5304 It was old code and did not handle the reallocation correctly.
5307 The affected file is lib/silccore/silcpacket.c.
5309 * Fixed buffer overflow in silc_parse_nickname in the file
5310 lib/silcutil/silcutil.c.
5312 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5314 * make install generates new server keys only if there is not
5317 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5319 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5320 Added check that if the NOREPLY is set then we will not send
5321 the away message. This avoids infinite loop of away messages
5322 if both clients are away. The affected file is
5323 lib/silcclient/client_prvmsg.c.
5325 * Fixed client crash if /NICK was given without arguments.
5326 Affected file lib/silcclient/command.c.
5328 * Server does not send the invite list in INVITE command back
5329 to the client if the list was not altered. Added this notion
5330 to the protocol spec as well. Affected file silcd/command.c.
5332 Fixed possible crash in INVITE command by checking the
5333 value of silc_server_get_client_route command.
5335 * Fixed the INVITE notify type handling. The arguments are now
5336 taken in correct order and client does not crash. The affected
5337 file is irssi/src/silc/core/silc-channels.c.
5339 Removed the "Inviting xxx to channel" message from the
5340 client library away and let the application handle it.
5341 Affected file lib/silcclient/command.c. Added that message
5342 to Irssi SILC client's message formats.
5344 * Fixed CMODE command crash in client. It now checks the
5345 amount of arguments correctly and does not crash. The affected
5346 file is lib/silcclient/command.c.
5348 * Do not create new channel automatically in silc_channels_join
5349 but check whether the channel by that name already exists.
5350 Affected file irssi/silc/core/silc-channels.c.
5352 * Do not send the SERVER_SIGNOFF to router if the disconnected
5353 entity was the router. Affected file silcd/server.c.
5355 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5356 SILC client as it was missing from there.
5358 Added the handling of the KICK notify to the Irssi SILC client
5359 as it was missing. Added "you have been kicked" message to
5360 Irssi SILC client's message modules formats.
5362 Added the handing of the KILL notify to the Irssi SILC client
5363 as it was missing. Added the kill message module formats
5366 The affected file is irssi/src/silc/core/silc-channels.c.
5368 * The router did not save the channel mode the server announced.
5369 Affected file silcd/packet_receive.c.
5371 * Fixed a possible crash in INFO command in server. If the
5372 server did not provide the server info it crashed. Affected
5373 file silcd/command.c.
5375 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5377 * Fixed the GETKEY command in the server to check also the
5378 global list. Otherwise the GETKEY would not work correctly
5379 in normal SILC server. Affected file silcd/command.c.
5381 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5383 * Fixed GETKEY crash, it crashed if the command did not succseed.
5385 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5387 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5388 is now real and not just an macro interface to GMP.
5390 Removed the entire GMP from the source tree and imported new
5391 NSS MPI library instead. Reason for removing GMP is that it is
5392 extremely large and compiles extremely slow. The NSS MPI
5393 is only a few files and compiles in less than 10 seconds.
5394 The speed is also about the same as GMP. The MPI is imported
5395 to lib/silcmath/mpi.
5397 If the system has GMP installed we will still use the GMP.
5398 If it is not then the NSS MPI will be compiled.
5400 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5402 * Merged a long nickname (127 characters long) crash bugfix from
5403 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5405 * Merged a freed memory reference bugfix from Irssi CVS tree.
5406 Affected file irssi/src/core/commands.c.
5408 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5410 * Added the server's public key sving and verification to the
5411 server when performing the SKE. This was missing and the
5412 remote server's (or router's) public key was accepted without
5413 checking whether we have it previously or trust it at all.
5414 Affected file silcd/protocol.c.
5416 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5418 * Check in the silc_server_timeout_remote if protocol is active
5419 and make sure that the protocol's final callback is called so
5420 that all memory if freed. Affected file silcd/server.c.
5422 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5424 * silc_server_whois_send_reply crashed the server if the nickname
5425 was 127 characters long. Affected file silcd/command.c.
5427 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5429 * Added sanity check to the silc_server_new_client. If the hostname
5430 is provided inside username then check that the provided hostname
5431 really is the same as the resolved one. If the hostname was not
5432 resolved then check it from the public key. Affected file is
5433 silcd/packet_receive.c.
5435 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5436 if the server disconnected us and the connection is not valid
5437 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5439 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5440 the library to the lib/silcutil/silcutil.[ch].
5442 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5444 * Close log file after open. Affected file
5445 lib/silcutil/silclog.c.
5447 * Check whether sock == NULL in silc_client_send_packet and return
5448 if it is. Affected file lib/silcclient/silcclient.c.
5450 * Check rec->entry == NULL in the Irssi SILC Client before
5451 sending the channel message. Affecte file is
5452 irssi/src/silc/core/silc-servers.c.
5454 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5456 * Merged a splitted window bugfix from Irssi CVS tree. The
5457 affected file is irssi/src/fe-text/textbuffer-view.c.
5459 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5460 It did not print nickname.
5462 * Improved the distributions system a bit.
5464 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5466 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5467 irssi/src/fe-text/gui-window.c.
5469 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5470 to in-active server. The affected file is
5471 irssi/src/silc/core/client_ops.c.
5473 * Resolve the client in USERS command reply if the entry does
5474 not have username resolved. The affected file is
5475 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5476 command to WHOIS command to really resolve stuff. The USERS
5477 is not used any more in any critical section so WHOIS can
5478 be used even though it might be slower than IDENTIFY.
5480 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5483 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5485 * Changed the protocol API a bit more consistent in the
5486 lib/silccore/silcprotocol.[ch].
5488 * Changed the following headers to ROBODoc format:
5490 lib/silccore/silcpayload.h
5491 lib/silccore/silcprotocol.h
5492 lib/silccore/silcsockconn.h
5494 All core library headers are now formatted.
5496 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5498 * Fixed a bug in Irssi SILC client; do not show that you are
5499 server/router operator if you really are not. Affected file is
5500 irssi/src/silc/core/client_ops.c.
5502 * Renamed silc_command_free_payload to silc_command_payload_free.
5503 Affected file lib/silccore/silccommand.h
5505 * Added silcmath.h to include the prototoypes of various routines
5506 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5509 * Changed the following headers to ROBODoc format:
5511 lib/silccore/silcchannel.h
5512 lib/silccore/silccommand.h
5513 lib/silccore/silcid.h
5514 lib/silccore/silcidcache.h
5515 lib/silccore/silcmode.h
5516 lib/silccore/silcnotify.h
5517 lib/silccore/silcpacket.h
5518 lib/silcmath/silcmath.h
5520 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5522 * Added checking to the server code not to start the server if
5523 ciphers and stuff are not configured properly. Affected files
5524 silcd/serverconfig.[h] and silcd/server.c.
5526 * Changed the layout of the header files of the public interfaces
5527 in the SILC libraries. The new layout supports ROBODoc
5528 documentation tool (and some others) so that it is easy to create
5529 a library reference manual. All the other headers and source
5530 code must still follow the CodingStyle document. Also source
5531 code must not include these ROBODoc stuffs, only the headers.
5532 Furthermore, all public interface headers must now be named
5533 by using `silc' prefix, example: silcapi.h, silccipher.h.
5534 Some files were renamed due to this. All the other headers
5535 must not be used as public interfaces. I will update the
5536 CodingStyle document later. Changed following headers, so far:
5538 lib/silcclient/silcapi.h
5539 lib/silccore/silcauth.h
5540 lib/silccore/silcprivate.h
5541 lib/silccrypt/silcdh.h
5543 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5547 * Removed silc_client_packet_send_flush from the client library
5548 as it is not needed. Affected file lib/silcclient/client.[ch].
5550 * Added printing of message of unresolved authentication method
5551 to the Irssi SILC client. Added it to the module formats.
5552 Removed the same message from the client library.
5554 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5556 * Added new distribution feature, DISTLABEL. Every distribution
5557 can define own preprocessor label that can be used in the
5558 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5559 file distributions, acconfig.h.pre and prepare.
5561 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5563 * Added Makefile.defines_int to include the actual definitions
5564 for Makefile.defines.in. Tested the new distribution system,
5565 created distributions and tested installation.
5567 * Added AWAY message printing to the Irssi SILC client. Added
5568 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5570 * Added SCONNECT command to call the SILC's CONNECT command.
5571 Cannot use CONNECT directly since Irssi uses that internally.
5572 Affected file irssi/src/silc/core/silc-servers.c.
5574 Added ACTION local command. It is same as ME command but takes
5575 the channel as mandatory argument.
5577 Rewrote some of the Irssi's help files to suite for SILC
5580 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5582 * Added Makefile.defines[.in] that should for now on be included
5583 in all Makefile.am file in the source tree. That file includes
5584 all common compilation definitions for SILC source tree.
5586 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5588 * Minor changes to the ./prepare script to change the package
5589 name according the distribution name to the configure.in.
5591 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5593 * Created new distribution system. Added file `distributions'
5594 that defines all the distributions that can be created out of
5595 the SILC source tree. The ./prepare script now reads that
5596 file to determine how to prepare the distributions. The
5597 first argument to the ./prepare is the name of the distribution
5598 and second is the version of the distribution. If given
5599 without arguments it creates the default (toolkit) distribution
5600 with the default version (defined in ./prepare).
5602 All Makefile.am files that are subject to the distributions
5603 are now named as Makefile.am.pre. These are ./Makefile.am
5604 and lib/Makefile.am. Others may be changed later.
5606 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5608 * Added invite list, ban list, some key management and connection
5609 error message printing to module formats in the Irssi SILC client.
5611 * Added new silc_client_set_away_message to set the away message
5612 that is back to the person who sent private message. The
5613 affected file lib/silcclient/silcapi.h and the
5614 lib/silcclient/client_prvmsg.c.
5616 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5618 * Fixed the private message sending in the Irssi SILC client,
5619 added local command KEY to the Irssi SILC client.
5621 Added key management and key agreement message formats to the
5622 irssi/src/fe-common/silc/module-formats.[ch].
5624 Added USERS (alias WHO) printing, server/router operator
5625 indication and LIST command printing to the module formats.
5627 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5629 * Fixed channel joining notify handling, cumode notify handling
5630 from Irssi SILC client.
5632 * Added SILC specific module-formats to the Irssi SILC client so
5633 that SILC specific message hilighting, colors etc is possible.
5634 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5636 Added channel mode, channel user mode, actions, notices,
5637 whois and whowas printing to the the module-formats.c.
5639 * Fixed a bug in channel deletion in the server. The channel
5640 is not left to the cache even if the channel founder auth mode
5641 is set when there are no users anymore on the channel. Affected
5642 file silcd/server.c.
5644 * The silc_net_localhost now resolves the entire hostname including
5645 the domain name. Affected file lib/silcutil/silcnet.c.
5647 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5649 * Changed the ask_passphrase client operation to be ascynchronous.
5650 It has now a completion callback and a context that the
5651 application must call after it has got the passphrase from
5652 the user. Affected files lib/silcclient/silcapi.h,
5653 lib/silcclient/protocol.c, lib/silcclient/command.c and
5656 Added SilcAskPassphrase callback that the application calls
5657 to deliver the passphrase to the library.
5659 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5660 The public key verification and especially a certificate
5661 verification is asynchronous procedure.
5663 Added new SILC_SKE_STATUS_PENDING status to indicate the
5664 request is pending and a callback will be called to finalize
5667 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5668 indicate that remote end did not send its public key (or
5669 certificate), even though we require it. Added check for this
5670 condition in the SKE. This was a security bug, now fixed.
5672 Defined new SilcSKEVerifyCbCompletion callback that is called
5673 when the verification process is completed.
5675 The affected files lib/silcske/silcske_status.h and
5676 lib/silcske/silcske.[ch].
5678 * Changed the verify_public_key client operation to be async
5679 as well. Defined SilcVerifyPublicKey callback that is used to
5680 indicate the success of the public key verification process.
5682 Changed the server and client to use the new async client
5685 * Changed the Irssi SILC client's internal scheduler to be called
5686 twice as many times as it used to be. As a result the client
5687 should be a bit faster now. Affected file is
5688 irssi/src/silc/core/silc-core.c.
5690 * Added support to Irssi SILC client of asynchronous public key
5691 verification and passphrase inquiry. Affected file is
5692 irssi/src/silc/core/silc-core.c.
5694 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5696 * Do not say "You have left channel %s" in client library.
5697 Moved it to the application. Affected files are
5698 lib/silcclient/command.c and silc/client_ops.c.
5700 * Fixed silc_client_get_clients. Command context was not
5701 duplicated and was freed memory in the callback. Affected
5702 file lib/silcclient/idlist.c.
5704 * Do not say "you are now talking..." on JOIN command in the
5705 client library. The appliation must handle it.
5707 * Do not say ".. changed topic to" in command reply in the
5708 client libary. The application must handle it.
5710 * Fixed TOPIC command sending in the client library.
5712 * Fixed a memory leak in silc_client_command_free in the file
5713 lib/silcclient/command.c.
5715 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5717 * Imported a modified version of Irssi client to the source tree.
5718 The Irssi will be used to create a new client called
5719 Irssi SILC. Imported to irssi/.
5721 Added silc_core_init_finish function to the Irssi. Affected
5722 file irssi/configure.in.
5724 A lot changes in the Makefile.ams around the irssi tree.
5726 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5728 * Do not rehash if the new size is same as the old size of the
5729 hash table, in the silc_hash_table_rehash*. The affected file
5730 lib/silcutil/silchashtable.c.
5732 * Replaced hash_table_del_by_context calls from the server
5733 (when channel->user_list and client->channels) to the
5734 hash_table_del as it is sufficient and faster.
5736 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5738 * Added silc_hash_table_list, silc_hash_table_get and the
5739 SilcHashTableList structure to provide an alternative way to
5740 traverse the hash table. The affected files are
5741 lib/silcutil/silchashtable.[ch].
5743 * Changed the server's idlist routines to use the hash table
5744 routines to optimize the code.
5746 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5748 * Replaced the client entry's `channel' list and channel entry's
5749 `user_list' list to hash tables for optimized lookup. Changed
5750 the code to use the hash table interface around the code.
5751 Affected file lib/silcd/idlist.[ch].
5753 * Added `auto_rehash' boolean argument to the function
5754 silc_hash_table_alloc to indicate whether the hash table should
5755 auto-rehash when it thinks is appropriate time. It will
5756 increase the hash table size if the there is twice as much
5757 entries in the table than the size of the table, and will
5758 decrease the size if there are twice as less entries than
5759 the size of the table.
5761 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5763 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5765 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5767 * silc_idcache_purge_by_context deletes the entry now by context
5768 as it is supposed to do. Affected file lib/silccore/idcache.c.
5770 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5771 client is not anymore valid (WHOWAS givens the info) and not
5772 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5774 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5776 * Removed the `data' and `data_len' arguments from the ID Cache
5777 interfaces and added `name' argument. ID Cache does not handle
5778 anymore the binary data only a names associated with given ID.
5780 * When hashing a Client ID with silc_hash_id the entire ID is
5781 not hashed anymore, instead only the hash of the Client ID is
5782 hashed. This way we can access the Client ID from the cache
5783 with Client ID but with the hash of the ID (which is a hash of
5784 the nickname) as well without any difference in performance.
5786 Added also silc_idcache_find_by_id_one_ext to do one on one
5787 searching when we have the actual ID. Added also function
5788 silc_hash_client_id_compare. The affected files are
5789 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5791 * When hashing the name associated with a ID it is always done
5792 in lowercase. This way we can access the cache without worrying
5793 about case-sensitivity, even though, for example nicknames are
5796 * Fixed a bug in server with channel message sending. It put
5797 wrong ID type as destination ID. The affected file
5798 silcd/packet_send.c.
5800 * silc_idcache_del_by_context now deletes from all hash tables
5801 by context. Affected file lib/silccore/idcache.c.
5803 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5805 * Changed the client library to use the new ID Cache interface.
5806 Changes around the source tree.
5808 * Added silc_hash_table_rehash_ext to rehash with specific
5809 hash function. Affected file lib/silcutil/silchashtable.[ch].
5811 * Added silc_hash_string_compare to compare two strings in the
5812 hash table. Affected file lib/silcutil/silcutil.[ch].
5814 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5816 * Added new function silc_idcache_del_by_context into the
5817 lib/silccore/idcache.[ch].
5819 * Changed the server's ID list routines to use the new ID Cache
5820 interface. Changes around the source tree.
5822 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5824 * Added silc_hash_table_del[_by_context]_ext functions in to the
5825 lib/silcutil/silchashtable.[ch].
5827 Removed silc_hash_table_find_all* routines and added new
5828 silc_hash_table_find_foreach to replace them.
5830 Added silc_hash_table_replace_ext function as extended
5831 replacing function. Separated the simple hash table interface
5832 from the extended hash table interface in the file
5833 lib/silcutil/silchashtable.h.
5835 * Fixed minor bugs and changed it to use some of the new
5836 hash table functions in lib/silccore/idcache.c
5838 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5840 * Added new function silc_hash_table_find_all to return all keys
5841 in the hash table by the specified key. As the hash table is
5842 collision resistant it also makes it possible to have several
5843 duplicate keys in the hash table. This function may be used to
5844 find all of the keys from the hash.
5846 Added user_context arguments to the SilcHashFunction,
5847 SilcHashCompare and SilcHashDestructor to deliver user specified
5850 Added new fuctions silc_hash_table_find[_all]_ext to do
5851 extended lookup with specified hash and compare functions and
5852 specified user contexts.
5854 Added new function silc_hash_table_add_ext to add the key
5855 with specified hash function and user context.
5857 Added new function silc_hash_table_foreach to traverse all
5858 entrys in the hash table. Added SilcHashForeach callback
5861 Added new function silc_hash_table_del_by_context to delete
5862 the entry only if the context associated with the key matches.
5864 Affected files are lib/silcutil/silchashtable.[ch].
5866 * Removed silc_hash_[server/client/channel]_id and added just
5867 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5868 silc_hash_id_compare to compare two ID's using as the hash table
5869 comparison function. Added also silc_hash_data to hash
5870 binary data and silc_hash_data_compare to compare it.
5872 * Removed silc_idlist_find_client_by_hash as it is not needed
5873 anymore. Affected file silcd/idlist.[ch].
5875 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5876 to use internally the SilcHashTable. The new ID Cache is a lot
5877 faster than the old one. Some of the ID Cache interface was also
5878 rewritten and obsolete and stupid functions were removed.
5880 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5882 * Added entry_count field to the SilcHashTable to keep the number
5883 of the entries in the table. Implemented the function
5884 silc_hash_table_rehash. Added new function
5885 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5887 Fixed a minor bug in silc_hash_table_free.
5889 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5890 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5891 into the lib/silcutil/silcutil.[ch].
5893 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5895 * Implemented a collision resistant hash table into the
5896 lib/silcutil/silchashtable[ch]. See the header and the source
5897 for the SilcHashTable API.
5899 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5901 * Merged dotconf version 1.0.2 into lib/dotconf.
5903 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5905 * Do not compile anything in lib/silcsim/* if the SIM support
5906 is not enabled. The tree should now compile without problems
5909 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5911 * Compiled the SILC under cygwin. Compiled and tested briefly
5912 without problems. More tests needed. The SIMs didn't compile
5915 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5917 * Fixed possible crash in silc_get_username in the
5918 lib/silcutil/silcutil.c.
5920 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5922 * Fixed a va_arg in silc/client_ops.c.
5924 * Oops, RC5 routines were named AES and caused some problems
5925 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5927 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5929 * Added new SilcIDIP structure into the lib/silccore/id.h and
5930 replaced the old `ip' fields from all SILC ID's to that type.
5931 This is a step towards IPv6 support.
5933 The silc_id_get_len takes now the ID as an extra argument.
5934 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5935 both IPv4 and IPv6 based ID's.
5937 The affected files are lib/silccore/id.[ch] and other files
5938 around the tree using these routines.
5940 * Removed the ID length arguments in server from various
5941 silc_server_send_notify_* routines -> they are not needed
5944 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5946 * Fixed memory leak in silc_encode_pem_file in the file
5947 lib/silcutil/silcutil.c.
5949 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5951 * Check minor version as well in the SKE. Affected files are
5952 silcd/protocol.c and lib/silcclient/protocol.c.
5954 * Added --identifier option to the server so that an identifier
5955 can be when creating the public key for the server. Affected
5956 file is silcd/silcd.c.
5958 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5959 lib/silccrypt/silcpkcs.c.
5961 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5963 * Register default ciphers and stuff when using -C option with
5964 the server. Affected file sildc/silcd.c.
5966 * Put back the servers public key filename format, it is better
5967 than the new one. For now, the client keys are saved with the
5968 new filename format. The affected file silc/client_ops.c.
5970 * Implemented the Cipher API for the rest of the ciphers that
5971 did not implement it or implemented it the wrong way.
5973 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5975 * Register default ciphers and stuff when using the -S option
5976 in the client. Affected file silc/silc.c. Same also when
5977 creating new key pair with -C option.
5979 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5981 * Fixed the silc_verify_public_key client operation function to
5982 save the public keys differently. The fingerprint is now
5983 used as filename and not the hostname. This way also the
5984 client keys are saved uniquely and not with hostnames. The
5985 affected file is silc/client_ops.c.
5987 * Trimmed the silc_hash_fingerprint function to remove extra
5988 whitespaces from the end of the fingerprint. The affected
5989 file is lib/silccrypt/silchash.c.
5993 * Added silc_cipher_register_default function to register all
5994 default ciphers. It can be used when configuration files
5995 does not exist and the application does not want any specific
5996 ciphers in any specific order.
5998 The SilcDList is now used as silc_cipher_list dynamically
5999 allocated cipher list. Removed the static list all together
6000 and now all ciphers must be allocated to the dynamic list.
6001 The silc_cipher_alloc routine was changed to check only the
6004 All silc_cipher_* routines that used to return int returns
6007 The affected files lib/silccrypt/silccrypt.[ch].
6009 * The same thing was done to silc_hash_* as for silc_cipher_*
6010 routines. Affected files lib/silccrypt/silchash.[ch].
6012 * The same thing was done to silc_pkcs_* as for silc_cipher_*
6013 routines. Affected files lib/silccrypt/silcpkcs.[ch].
6014 Added also silc_pkcs_[un]register[_default] functions.
6015 Removed the data_context from the PKCS API.
6017 * Added silc_hmac_register_default function to register default
6018 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
6019 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
6020 to unregister all hmacs at once.
6022 * Register the default ciphers, hash functions, PKCSs and HMACs
6023 if client's configuration file does not exist. The affected
6026 * The client did not load the hash functions from the SIM
6027 modules at all. Added support for this. Affected file is
6028 silc/clientconfig.c.
6030 * When decoding public key with silc_pkcs_public_key_decode, check
6031 the supported algorithm only if PKCS are registered. Affected
6032 file lib/silccrypt/silcpkcs.c. The same was done with the
6033 silc_pkcs_private_key_decode.
6035 * Fixed the SILC List routines to keep the list always in order.
6036 It used to change the list's order when traversing the list but
6037 not it preserves the order. Affected file lib/trq/silclist.h.
6039 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6041 * Added the client library to use the SilcSocketConnection's
6042 reference counter (by silc_socket_dup) to prevent the bug that
6043 the socket object may be freed underneath async operation.
6045 * The name resolv library checking fixes in the configure.in.pre.
6048 * Created new version of the protocol drafts for future
6049 development. The -03 drafts are the ones that will be changed
6050 in the trunk now and the -02 will remain as they are.
6052 * Send list of CUMODE notifys to the router when announcing
6053 the channel users to the router. Affected file silcd/server.c.
6054 If the router receiving channel founder CUMODE for a channel
6055 that already has channel founder it will send CUMODE notify
6056 to the sender to remove the channel founder rights from the
6057 announced client. Affected file silcd/packet_receive.c.
6059 * The CUMODE notify may now use Server ID as well as the entity
6060 who changes the mode. Updated protocool specs.
6062 * Updated INSTALL and README files.
6064 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6066 * New web pages in the http://silc.pspt.fi. The pages was
6071 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6073 * Implemented the [DenyConnectin] config section in the server.
6074 Added silc_server_config_denied_conn to check whether incoming
6075 connection is denied. Affected file silcd/serverconfig.[ch].
6077 * Do not check the ports when checking the incoming configuration
6078 data if the port is 0, meaning any. Affected file is
6079 silcd/serverconfig.c.
6081 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6083 * Fixed buffer overflow in silc_string_compare in the file
6084 lib/silcutil/silcutil.c.
6086 * Fixed double free in silc_server_command_leave in the file
6089 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6091 * Fixed the version checking in the server. Affected file is
6094 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6096 * Fixed the configuration data fetching when accepting new
6097 connections in the server. Affected file silcd/server.c.
6099 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6101 * Added `sender_entry' argument to the function
6102 silc_server_packet_relay_to_channel so that we can check
6103 whether some destination actually belongs to the same route
6104 the sender belongs (ie, we must not resend the packet to the
6105 sender). Affected file silcd/packet_send.[ch].
6107 * Added `servername' field to the SilcClientEntry in the server
6108 to hold the name of the server where client is from. Affected
6109 file is silcd/idlist.h.
6111 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6113 * Moved the channel message encrypting in the router betwen
6114 router connections from silc_server_channel_message to the
6115 silc_server_packet_relay_to_channel since we want to check
6116 whether we have anybody channel before encrypting anything.
6117 Affected files silcd/packet_[receive/send].c.
6119 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6121 * Fixed the [AdminConnection] server config section to support
6122 multiple entries. Affected file silcd/serverconfig.c.
6124 * Added support into the server to check the validity of the
6125 incoming connection before executing any KE or authentication
6128 * The connection configuration is now saved to the KE and
6129 connection auth protocol contexts and not fetched anymore in
6130 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
6132 * The local hosts listenning address and port is also resolved
6133 now when starting the server. We want to have the socket object
6134 to include the real address and port for the listener. Added
6135 new function silc_net_check_local_by_sock into the files
6136 lib/silcutil/silcnet.[ch].
6138 * Fixed a broadcast bug in server -> do not broadcast if we
6141 * Fixed a routing bug. Do not route broadcast packets ever.
6142 Broadcast packets must be processed always and not routed since
6143 they may be destined to some other host than yourself and thus
6144 would get routed without no good reason. Affected file is
6147 * Added function silc_server_config_is_primary_route to check
6148 whether primary router connection has been configured (a router
6149 configuration that we are initiating). If there is not, we
6150 will assume that there is only two routers in the SILC network
6151 and we will use the incoming router connection as our primary
6152 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
6154 * Changed the order of the broadcasting. Broadcast _after_ the
6155 packet has been processed not before. Affected file is
6158 * Fixed a [ClientConnection] parsing bug. The port was never
6159 parsed correctly thus resulting to port 0. Affected file
6160 silcd/serverconfig.c.
6162 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
6163 argument and did not set the broadcast packet flag. Affected
6164 file silcd/packet_send.c. Fixed same bug in the function
6165 silc_server_send_notify as well.
6167 * If we receive NEW_ID packet for our own ID in the server, ignore
6170 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6174 * Removed the nickname from the Private Message Payload.
6175 Updated the code and the protocol specs.
6177 * Updated protocol specs for submitting to the IETF.
6179 * Tweaked the Random Number Generator a bit. Affected file
6180 lib/silccrypt/silcrng.c. Exported a new function
6181 silc_rng_[global]_add_noise which can be used to add more
6184 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6186 * Do not parse packets with different timeout when protocol
6187 is active -> may cause problem with rekey. Affected file
6190 * When server receives signoff notify it must not create
6191 new channel key if the client is on any channels since the
6192 sender of the signoff notify will create it.
6194 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6196 * Added printing of error messages during SKE protocol from the
6197 failure packet sent by server during SKE. Affected file
6200 * Removed the client's failure_callback handling with timeout
6201 and handle it immediately when received.
6203 * The SKE library returned wrong type in SUCCESS and FAILURE
6204 packets. They must be 32 bit MSB not 16 bit MSB.
6206 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6208 * Ok, rewrote the logic of the re-key and now it seems to work.
6209 I tested it on high traffic with frequent re-keys without
6210 problems. Added hmac_receive (and renamed hmac to hmac_send)
6211 in SilcClientConnection in lib/silcclient/client.h and
6212 in SilcIDListData in silcd/idlist.h. Also, removed the
6213 SilcPacketParserContext's cipher and hmac fields as they are
6214 not needed anymore and actually caused some problems when
6215 the ciphers and hmac's changed underneath the packet parser.
6217 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6219 * If re-key protocol is active then process the incoming packets
6220 synchronously since we must assure that icoming packets encrypted
6221 with the old key is processed before the new keys is set to
6222 use. This is true other packets than for REKEY packets.
6223 Affected file silcd/server.c. The same was done to client library
6224 as well, affected file lib/silcclient/client.c.
6226 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6228 * Fixed bug in client and server to accept the force send if
6229 the packet is send from silc_[server/client]_packet_process
6230 function. Otherwise the packets are never delivered, oops.
6232 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6234 * Disable force sending of packets when REKEY protocol is active.
6235 We must assure that no packet is sent directly when rekey is
6236 performed. All packets must be sent through packet queue.
6237 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
6238 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
6239 function is silc_[server/client]_packet_send_real to check
6242 * Replaced the SIM paths from example config files to
6243 /usr/local/modules. Also, make install creates now
6244 /usr/local/silc/logs directory to hold all the SILC server
6247 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6249 * Made the configure.in.pre work on Solaris. Patch by salo.
6251 * Made all ciphers compatible with non-x86 machines. Defined
6252 CBC mode macros into lib/silccrypt/ciphers_def.h.
6254 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6256 * Fixed the make install.
6258 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * When MAC computation fails the silc_packet_decrypt returned 0
6261 even though it was supposed to return -1. Fixed this. The
6262 affected file is lib/silccore/silcpacket.c.
6264 * Do not replace the config files in /etc/silc (in make install)
6265 if they already exist. Affected file ./Makefile.am.
6267 * Do not send re-key packets immediately but through packet queue.
6268 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6270 * Changed silc_net_check_host_by_sock to return FALSE if the
6271 IP/DNS could not be resolved. Though, it returns the IP address
6272 now even if it could not resolve it (but returns also FALSE).
6273 Affected file lib/silcutil/silcnet.[ch].
6275 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

6283 contents of the specified public key file.
6285 * Changed the PKCS api to return the public key length when
6286 setting the public key.
6288 * Fixed a fatal bug in the public and private key file loading.
6289 Affected file lib/silccrypt/silcpkcs.c.
6291 * Execute the packet parsing for client with zero (0) timeout
6292 if the protocol is active. Affected file silcd/server.c.
6294 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6296 * Made the key generation options to the silcd program. Added
6297 -C option, equivalent to client's option.
6299 * Added new [ServerKeys] config section to the server. It
6300 configures the server's public and private key.
6302 * Defined generic Public Key Payload into the protocol
6303 specification to send specific type of public keys and
6306 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6307 public key or certificate.
6309 * Implemented the GETKEY command to the server and to the
6310 client library and on user interface.
6312 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

6316 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6318 * Added SilcServerRekey context into silcd/idlist.h.
6320 * Added the PFS support as defined in the specification to the
6321 SKE protocol. Affected files lib/silcske/*.c.
6323 * Added `ske_group' field to the SilcServerRekey context to hold
6324 the number of the SKE group that is used with PFS in re-key.
6325 Affected file silcd/idlist.h.
6327 * Added PFS re-key support to the server. Affected file is
6330 * Added silc_protocol_cancel to cancel execution of the next
6331 state of the protocol. Affected file is
6332 lib/silccore/silcprotocol.[ch].
6334 * Added the re-key support with and without PFS to the client
6335 library. Re-key is performed once in an hour, by default.
6337 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6338 Added silc_client_rekey_callback and silc_client_rekey_final.
6339 Affected files are lib/silcclient/protocol.[ch] and
6340 lib/silcclient/client.[ch].
6342 * Removed the `hmac_key' and `hmac_key_len' fields from the
6343 SilcClientConnection structure; not needed. Affected file is
6344 lib/silcclient/client.h.
6348 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6350 * Do not ask whether user wants to use the negotiated private key
6351 for private messages, just use it. Affected file is
6352 silc/local_command.c.
6354 * Added `send_enc_key' and `enc_key_len' fields to the
6355 SilcIDListData structure since they are needed in the re-key
6356 phase. Affected file is silcd/idlist.[ch].
6358 * Implemented the simple re-key protocol into the server.
6359 Affected files silcd/server.c and silcd/protocol.[ch]. The
6360 re-key will be performed once in an hour, by default.
6362 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6363 Added silc_server_rekey, silc_server_rekey_callback and
6364 silc_server_rekey_final.
6366 * Removed Tunneled flag from the protocol. Updated the code
6367 and the specifications.
6369 * Adde `pfs' field to the SilcIDListData to indicate whether
6370 the PFS is to be performed in the re-key. Affected file is
6373 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6375 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6376 int64 of at least the xintXX size. If void * is less that 4
6377 bytes uint32 * will be used. Defined bool as boolean.
6379 * Changed _ALL_ unsigned long and unsigned int to uint32,
6380 unsgined short to uint16 in the source tree.
6382 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6383 not handle clients that has entry->data.registered == FALSE.
6384 They are not in the network anymore. Affected file is
6387 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6389 * Implemented the sending of the SERVER_SIGNOFF notify in the
6390 server. Affected file is silcd/server.c.
6392 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6393 Added also silc_notify_payload_encode_args into the
6394 lib/silccore/silcnotify.[ch].
6396 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6397 Affected file silcd/packet_receive.c.
6399 * Implemented the SERVER_SIGNOFF notify handling in the client
6400 library. Affected file lib/silcclient/client_notify.c. Also,
6401 implemnted the printing of the SERVER_SIGNOFF info to the
6402 application. Affected file silc/client_ops.c.
6404 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6405 if the deleting was successful. Affected file silcd/idlist.[ch].
6407 * Added support for public key authentication in the connection
6408 authentication protocol in the client library. Affected file
6409 lib/silcclient/protocol.c.
6411 * Changed the server's silc_idlist_get_clients_by_* interface
6412 to support already allocated array so that new entries may be
6413 added to pre-allocated array. Affected file silcd/idlist.[ch].
6414 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6415 and command replies.
6417 * All command reply functions in the server now calls the
6418 pending command callback even if error occured. This way the
6419 error will be delivered to the client as well. Affected files
6420 silcd/command.c and silcd/command_reply.c.
6422 * Fixed INFO command to return local server's info if no server
6423 was provided. Affected file lib/silcclient/command.c.
6425 * Removed RESTART command for good. Updated the code and the
6428 * Rewrote parts of the task system. It is a bit simpler now.
6429 Removed unsued task priorities. The affected files are
6430 lib/silcutil/silctask.[ch].
6432 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6434 * Moved the USERS printing from the library to the application.
6435 Affected files lib/silcclient/command.c and silc/client_ops.c.
6437 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6441 * Added channel key re-key support. The re-key is perfomed
6442 only by the router and is done once in an hour. Added `rekey'
6443 field to the SilcChannelEntry in the server. Affected files
6444 silcd/server.c and silcd/idlist.h.
6446 * Added silc_task_unregister_by_context into the file
6447 lib/silcutil/silctask.[ch].
6449 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6451 * Added SILC_UMODE_GONE mode to indicate when the client is not
6452 present in the SILC network. Added also support to the local
6453 command AWAY that will set this mode. Added support of showing
6454 "xxx is gone" in WHOIS command. The USERS command shows the
6455 gone status as well.
6457 * Fixed setting server and router operator privileges in the
6458 server's UMODE command. Affected file silcd/command.c.
6460 * Merged the SKE KE1 and KE2 payloads into one payload. The
6461 new KE payload is equivalent to the old KE2 payload.
6463 Cleaned up the SKE Start Payload parsing. It now uses the
6464 simple buffer unformatting to do the parsing. A lot faster
6467 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6468 to the SKE that is used to indicate whether both of the SKE
6469 parties should perform authentication. By default only the
6470 responder performs authentication. By setting this flag also
6471 the initiator must do authentication. By default it is unset
6472 since in normal SKE case, client to server connection, only
6473 the responder should do authentication. When doing SKE between
6474 two clients both should perform authentication. Updated the
6475 code and the protocol specs.
6477 * A little fix to IDENTIFY command in the server. Search the
6478 client first by hash not nickname. Affected file is
6481 * Fixed the silc_client_close_connection to support closing
6482 the client to client connections wihtout deleting too much
6483 data. Affected file lib/silcclient/client.c.
6485 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6486 are received if protocol used to be active but is not anymore
6487 the application would crash due to NULL pointer dereference.
6488 Affected files silcd/server.c and lib/silcclient/client.c.
6490 * Added `hash' field to the SilcClientConnection to include
6491 the hash function negotiated in the SKE protocol.
6493 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6494 to set the channel founder authentication data. A client can
6495 claim the founder rights later by providing the authentication
6496 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6497 This way the channel founder can regain the channel founder
6498 privileges even it is left the channel. This works only on
6499 local server and the client must be connected to the same
6500 server to be able to regain the founder rights. Updated the
6501 protocol specs accordingly.
6503 Added support to the CMODE command in the client to set the
6504 founder auth data. Read the README to see how to set it.
6506 Added support to the CUMODE command to claim the founder
6507 rights. Read the README to see how to do it.
6509 Added support for the founder authentication to the Channel
6510 Entry in the server. Affected file silcd/idlist.h.
6512 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6513 server's CMODE command. Affected file silcd/command.c.
6515 * Added the following new functions into lib/silccore/silcauth.[ch]:
6516 silc_auth_get_method and silc_auth_get_data.
6518 * The server now saves the remote hosts public key to the
6519 SilcIDListData pointer. Affected file silcd/protocol.c.
6521 * The normal server now does not remove the channel entry from
6522 the cache if the founder authentication data is set. It used
6523 to remove it if the founder was the last one on the channel on
6524 the server and left the channel. The auth data is saved and
6525 if the channel is re-joined later the old entry is used with
6526 the old auth data. Affected files silcd/command_reply.c and
6529 * Removed the `pkcs' field from the SilcIDListData structure
6530 in the server; it is not used. Affected file silcd/idlist.h.
6532 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6534 * Fixed packet processing on slow links. Partial packets were
6535 never re-processed because the incoming data buffer was cleared
6536 by the application. Application must not directly clear the
6537 sock->inbuf, the packet processing routines handle it. Fixed
6538 this in client library and in server.
6540 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6542 * Fixed the WHOIS and IDENTIFY send reply function to really
6543 check whether to send list or just one entry. Affected file
6546 * Cleaned up the LEAVE command's channel key distribution. The
6547 affected file silcd/command.c.
6549 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6550 can enforce the channel mode as well. In that case the ID
6551 includes the ID of the server. The code now enforces the
6552 mode change if the router have different mode than the server.
6554 * The notify client operation with CMODE_CHANGE notify can now
6555 return NULL client_entry pointer if the CMODE was not changed
6556 by client. Application must check for this.
6558 * Added <Server ID> argument to INFO command to support server
6559 info fetching by Server ID.
6561 * Added silc_server_announce_get_channel_users to get assembled
6562 packets of channel users of the specified channel. Affected
6563 file silcd/server.[ch].
6565 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6566 was freed underneath the ID Cache.
6568 * Re-announce clients when the server received CHANNEL_CHANGE
6569 notify from the router. Affected file silcd/packet_send.c.
6571 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6573 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6574 crashed since it did not handle the fact that there is no cipher
6575 called "3" and didn't check the error condition. Now fixed.
6577 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6578 flag. It can be used to send message requests.
6580 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6582 * Implemented the RESTART command in the client.
6584 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6585 notice type messages. Added notice printing to the user
6588 * The channel keys are not re-generated if the channel's mode
6589 is PRIVKEY, ie private key on the channel exists. Affected
6590 files silcd/server.c and silcd/command.c.
6592 * Fixed a little bug in channel message delivery when channel
6593 private keys are set in the server. Affected file is
6594 silcd/packet_send.c.
6596 * Changed the setting on channel->on_channel = TRUE from the
6597 silc_client_save_channel_key to the JOIN command reply. The
6598 key payload is not received if the private channel key is set.
6599 Affected file lib/silcclient/command_reply.c and the
6600 lib/silcclient/client_channel.c.
6602 * When the CMODE_CHANGE notify is sent and the channel private
6603 key mode is removed the channel key must be re-generated in
6604 other cells as well. Added this support for the router in the
6605 silcd/packet_receive.c.
6607 * Added new local command NOTICE to send notice message on
6608 channel. Affected file silc/local_command.[ch].
6610 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6612 * Added new local command ME to the client. It is used to send
6613 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6614 some action. Affected file silc/local_command.[ch].
6616 * Changed channel_message and private_message client operations
6617 to deliver the message flags to the application. Added also
6618 the `flags' arguments to the silc_client_send_channel_message
6619 and silc_client_send_private_message functions. Affected file
6622 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6624 * Redefined the Private Message Payload to support private message
6625 keys and to support the new private message flags. Updated
6626 the protocol specs. Flags makes it possible to have for example
6627 CTCP style messages.
6629 * Added new type SilcPrivateMessagePayload and defined an API
6630 for it in the lib/silcclient/silcprivate.[ch].
6632 * Tested private message private keys successfully. Tested the
6633 private message key set, unset and list commands with the new
6636 * Redefined the Channel Message Payload to include the channel
6637 message flags (equal with private message flags) to support
6638 for example CTCP style messages.
6640 * Defined some of the message (for channel and private message)
6641 flags. Updated the protocol specs and added the flags to the
6642 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6644 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6646 * Added SilcKeyAgreementStatus type to the key agreement routines
6647 to indicate the current status and error if one occured.
6648 The status types are defined in the lib/silcclient/silcapi.h.
6650 * Added new local command KEY that is used to set and unset private
6651 keys for channels, set and unset private keys for private messages
6652 with remote clients and to send key agreement requests and
6653 negotiate the key agreement protocol with remote client. The
6654 key agreement is supported only to negotiate private message keys,
6655 it currently cannot be used to negotiate private keys for channels,
6656 as it is not convenient for that purpose.
6658 * Fixed a minor pending callback setting bug in the function
6659 silc_client_get_client_by_id_resolve, now the function works.
6660 Affected file lib/silcclient/idlist.c.
6662 * Added function silc_net_get_local_port to get local bound
6663 port by socket. Added to lib/silcutil/silcnet.[ch].
6665 * Added `sockets' and `sockets_count' fields to the SilcClient
6666 object. They hold the sockets of the listenning sockets in
6667 the client. Listenning sockets may be for example the key
6668 agreement server. Affected file lib/silcclient/client.[ch].
6669 Added functions the silc_client_add_socket and the
6670 silc_client_del_socket. They are exported to the application
6673 * Added ~./silc/clientkeys to support other client's public keys.
6675 * Renamed verify_server_key client operation to verify_public_key
6676 and added one argument to indicate the type of the connection
6677 (server, client etc.).
6679 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6681 * Added silc_server_connection_auth_request to handle the
6682 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6683 silcd/packet_receive.[ch].
6685 * Added silc_server_send_connection_auth_request into the
6686 silcd/packet_send.c to send the connection auth request packet.
6688 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6691 * Fixed the public key authentication in responder side in the
6692 server. The `auth_data' pointer includes the SilcPublicKey
6693 not the path to the public key. Affected file silcd/protocol.c.
6695 * Implemented the public key authentication in the initiator side
6696 in the server. Affected file silcd/protocol.c.
6698 * Removed the [RedirectClient] config section from the server
6699 configuration. Is not needed and I don't want to implement it.
6701 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6703 * Cleaned up the CMODE command in the server. It now works
6704 correctly and supports all the modes defined in the protocol.
6705 Affected file is silcd/command.c.
6707 * Added `hmac_name' field to the SilcChannelEntry in the server
6708 to hold the default HMAC of the channel. It can be set when
6709 creating the channel (with JOIN command). Affected files
6712 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6713 type to indicate the change of the current cipher and hmac
6714 on the channel. Client can safely ignore the <cipher> argument
6715 (if it chooses to do so) since the CHANNEL_KEY packet will
6716 force the channel key change anyway. The <hmac> argument is
6717 important since the client is responsible of setting the new
6718 HMAC and the hmac key into use.
6720 * Fixed the CMODE command in the client library as well.
6722 * Tested CMODE command in router environment successfully.
6724 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6726 * Show the version of the remote client (or server) when connecting
6727 to the server. It is logged to the log file. Affected file
6728 is silcd/protocol.c.
6730 * Fixed the KILLED notify handling in the client library. The
6731 client must be removed from all channels when receiving the
6734 Also, do not remove the client entry when giving the KILL
6735 command but when the KILLED notify is received.
6737 * Removed silc_idlist_find_client_by_nickname from the server.
6738 Not needed anymore. Affected files silcd/idlist.[ch].
6740 * Implemented the CHANNEL_CHANGE notify type handling to the
6741 server. Affected file silcd/server.c.
6745 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6747 * Added silc_server_send_notify_invite to send the INVITE
6748 notify between routers.
6750 * Implemented the INVITE command correctly to the server.
6752 * Implemented the INVITE notify type handling in the server.
6754 * Implemented the INVITE command to the client library and on the
6757 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6759 * Added function silc_server_get_client_resolve to find the
6760 client entry by ID from all ID lists and then resolve it
6761 (using WHOIS) if it cannot be found. Affected file is
6764 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6766 * Implemented the BAN command to the client library.
6768 * The JOIN command in the server now checks the invite list
6771 * Changed the silc_command_reply_payload_encode_va and the
6772 silc_command_payload_encode_va to support that if argument is
6773 NULL it ignores and checks the next argument. Affected file
6774 lib/silccore/silccommand.c.
6776 * Added silc_server_send_notify_ban to send the BAN notify
6777 type between routers.
6779 * Chaned the silc_notify_payload_encode to support that if
6780 argument is NULL it ignores and checks the next argument.
6781 Affected file lib/silccore/silcnotify.c.
6783 * Tested ban lists in router environment successfully.
6785 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6787 * Implemented BAN command to the server, in silcd/command.[ch].
6789 * Removed the BAN and INVITE_LIST modes from the CMODE command
6792 * Added function silc_string_match to regex match two strings.
6793 Affected files lib/silcutil/silcutil.[ch].
6795 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6797 * Redefined parts of the SilcChannelEntry in the server to support
6798 the new ban and invite lists.
6800 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6802 * Redefined the INVITE command. The same command can be used to
6803 invite individuals to the channel but also to manage the invite
6804 list of the channel (to add to and remove from the invite list).
6805 Updated the protocol specs.
6807 * Added new command SILC_COMMAND_BAN that can be used to manage
6808 the ban list of the channel. Updated the protocol specs.
6810 * Removed the channel modes: the SILC_CMODE_BAN and the
6811 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6812 in the CMODE command. The equivalent features are now available
6813 using INVITE and BAN commands. Updated the protocol specs.
6815 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6816 in the network about change in the current ban list. The notify
6817 type is not used by the client.
6819 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6820 support the invite lists.
6822 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6824 * Added new function silc_string_regexify that converts string
6825 including wildcard characters into regex string that can
6826 be used by the GNU regex library. Added into the file
6827 lib/silcutil/silcutil.[ch].
6829 Added silc_string_regex_combine to combine to regex strings
6830 into one so that they can be used as one regex string by
6831 the GNU regex library. Added into the file
6832 lib/silcutil/silcutil.[ch].
6834 Added silc_string_regex_match to match two strings. It returns
6835 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6837 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6839 * Imported GNU regex to the soruce tree into lib/contrib.
6840 Fixed some compiler warning from the regex.c.
6842 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6844 * Fixed MOTD command in the server to work in router environment.
6846 * Fixed the MOTD command in the client library to support
6847 the server argument in the command.
6849 * Added `nickname_len' argument to the silc_idlist_add_client
6850 in the server, as the `nickname' argument may be binary data
6853 * Added silc_idlist_get_channels to return all channels from
6856 * Implemented LIST command to the server. Affected file is
6859 * Implemented the LIST command to the client library and on the
6862 * Added [<user count>] argument to the LIST command reply.
6863 With private channels the user count is not shown.
6865 * Updated TODO and README.
6867 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6869 * The client entry's data.registered must be TRUE even with
6870 global client entry on global client list. The data.registered
6871 is used to check whether the client is anymore in the network,
6872 for example with WHOWAS command so it must be valid.
6874 * Fixed the WHOWAS command in the server. It now actually works
6875 in router environment. Added function into silcd/command_reply.c
6876 silc_server_command_reply_whowas_save.
6878 * Added silc_idlist_purge function to the silcd/idlist.c
6879 to periodically purge the ID Cache.
6881 * Fixed INFO command in the server. It works now in router
6882 environment. Added <server name> argument to the INFO command
6883 reply. Updated the protocol specs.
6885 * Fixed minor bug in silc_idcache_purge to not purge if the
6886 expire value is zero.
6888 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6889 they were buggy because of the WHOWAS information.
6891 * Fixed local command MSG to handle the async resolving of
6892 the remote client properly. It used to fail the first MSG.
6893 Affected file silc/local_command.c.
6895 * Added `data_len' field to SilcIDCache context.
6897 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6899 * Update TODO. Todo in commands in the server.
6901 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6903 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6904 used by routers as broadcast packet to inform other routers
6905 about the changed user mode.
6907 Implemented the notify handling in the server. Affected file is
6908 silcd/packet_receive.c. Added the function
6909 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6911 * Added new generic Channel Payload and deprecated the New Channel
6912 Payload. The New Channel Payload is now the generic Channel
6915 * Added new argument `mode' to the silc_server_send_new_channel
6916 as it is required in the Channel Payload now.
6918 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6919 and created a new and real SilChannelPayload to represent the
6920 new generic Channel Payload. Implemented the encode/decode
6921 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6923 * Added silc_server_get_client_channel_list to return the list
6924 of channels the client has joined for WHOIS command reply.
6925 Affected file silcd/server.[ch].
6927 * Implemented the channel list sending in the WHOIS command reply
6928 in server and in the client.
6930 Implemented the channel list displaying on the user interface
6931 as well. Affected file silc/client_ops.c.
6933 * Added silc_channel_payload_parse_list to parse list of Channel
6934 Payloads. It returns SilcDList list of SilcChannelPayloads.
6935 Client for example can use this function to parse the list of
6936 channels it receives in the WHOIS command reply. The caller
6937 must free the list by calling silc_channel_payload_list_free.
6938 Affected files lib/silccore/silcchannel.[ch].
6940 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6942 * Added one new argument <user mode> to the WHOIS command reply
6943 to return the mode of the user in SILC. Updated the protocol
6946 Implemented it to the server and client.
6948 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6950 * Fixed the mode printing on the user interface on joining.
6951 Affected file silc/client_ops.c.
6953 * Implemented the UMODE command and user modes in general to the
6954 client library and to the user interface.
6956 * Implemented the UMODE command to the server.
6958 * The server now sends UNKNOWN_COMMAND error status if client sends
6959 unknown command. Affected file silcd/command.c.
6961 * All server commands now handle the command identifier the right
6962 way when sending the command reply to the client. The client can
6963 use to identify the command replies with the identifier.
6965 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6967 * Added silc_server_get_client_route to resolve the route to
6968 the client indicated by the client ID. Affected file is
6971 * Added silc_server_relay_packet as general function to relay
6972 packet to arbitrary destination. This deprecates functions
6973 like _send_private_message_key, _relay_notify etc. Affected
6974 file is silcd/packet_send.[ch].
6976 Removed silc_server_send_key_agreement,
6977 silc_server_send_private_message_key and
6978 silc_server_packet_relay_notify functions from the file
6979 silcd/packet_send.[ch].
6983 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6984 server. Affected file silcd/packet_receive.[ch].
6986 * Implemented the KILL command to the client. Implemented the
6987 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6988 Affected files lib/silcclient/command[_reply].c and
6989 lib/silcclient/client_notify.c. Implemented the KILL notify
6990 printing in the user inteface.
6992 * Fixed a lot silc_parse_nick memory leaks from the client
6993 library in the file lib/silcclient/command.c.
6995 * Changed the silc_server_send_notify_on_channels's `sender'
6996 argument from SilcSocketConnection to SilcClientEntry to
6997 check the sender as entry and not as connection object and not
6998 to send to the client provided as argument. The affected file
6999 is silcd/packet_send.[ch].
7001 * The notify packets that are destined directly to the client used
7002 to not to be processed by the server. Now changed that and the
7003 server processes all notify packets. After relaying the packet
7004 to the client the notify packet is processed in the server.
7006 * The silc_server_free_client_data now checks whether there is
7007 pending outgoing traffic for the client and purges the data to
7008 the network before removing the client entry.
7010 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7012 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
7013 an client is killed from the SILC Network. Updated the protocol
7016 Added new function silc_server_send_notify_killed to the
7017 silcd/packet_send.[ch].
7019 * Added function silc_server_packet_relay_notify to relay notify
7020 packets that are destined directly to a client. In this case
7021 the server does not process the notify packets but merely relays
7022 it to the client. Affected file silcd/packet_send.[ch].
7024 Added also silc_server_packet_process_relay_notify to check
7025 whereto relay the notify. Affected file is
7026 silcd/packet_receive.[ch].
7028 * Implemented the KILL command to the server.
7032 * Added the backup schema desgined last fall to the protocol
7033 specs for everyone to see. The specification is in the
7034 *-spec-xx.txt draft and the packet type definitions for the
7035 backup routers is in *-pp-xx.txt draft. Thusly, added also
7036 new packet type SILC_PACKET_CELL_ROUTERS.
7038 * A big security problem in the implementation discovered. The
7039 signoff of an client did not cause new channel key generation
7040 which it of course should've done. The channel keys must be
7041 always re-generated when client leaves (or signoffs) the channel.
7042 The silc_server_remove_from_channels funtion now handles
7043 the channel key re-generation.
7045 * Added `sender' argument to the silc_server_send_notify_on_channels
7046 to not to send the client provided as argument. Affected file
7047 silcd/packet_send.[ch].
7049 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7051 * Implemented OPER and SILCOPER commands into the server and
7054 * Added silc_auth_verify and silc_auth_verify_data to verify
7055 the authentication directly from the authentication payload.
7056 It supports verifying both passphrase and public key based
7057 authentication. Affected file lib/silccore/silcauth.[ch].
7059 * Added `hash' field to the SilcIDListData structure. It is the
7060 hash negotiated in the SKE protocol. Affected file is
7063 * Slight redesigning of the SilcAuthPayload handling routines.
7064 Do not send SilcPKCS but SilcPublicKey as argument.
7066 * Implemented the public key authentication support to the
7067 serverconfig. The public key is loaded from the provided path
7068 and saved as authentication data to void * pointer. Thus,
7069 changed the unsigned char *auth_data to void *auth_data;
7071 * Fixed SHUTDOWN command to send the reply before the server
7072 is shutdown. :) Affected file silcd/command.c.
7074 * Fixed fatal bug in CONNECT command. The hostname was invalid
7075 memory and server crashed. Affected file silcd/command.c.
7077 * Fixed fatal bug in CLOSE command. The server_entry became
7078 invalid but was referenced later in the command. Affected file
7081 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7083 * Fixed fatal bug in failure packet handling. Server ignored
7084 the failure and thus crashed when it came.
7088 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7090 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
7091 that the command may be executed only once in (about) 2 seconds.
7092 The old SILC_CF_LAG flag is same but allows command bursts up
7093 to five before limiting.
7095 Added the support for CF_LAG and CF_LAG_STRICT flags to the
7096 server code. Various commands now includes the CF_LAG_STRICT
7097 flag to disallow any kind of miss-use of the command.
7099 * Fixed the silc_buffer_unformat to not to allocate any data
7100 if the length of the data is zero. It used to allocate the
7101 length + 1. Affected file lib/silcutil/silcbuffmt.c.
7103 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7105 * Changed the format of AdminConnection configuration section
7106 in the server. Added username of the admin to the format.
7107 Affected files silcd/serverconfig.[ch].
7109 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
7110 to return admin configuration data by host, username and/or
7113 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7115 * Implemented WHOWAS command to the server. Added the functions:
7117 silc_server_command_whowas_parse,
7118 silc_server_command_whowas_send_reply,
7119 silc_server_command_whowas_from_client and
7120 silc_server_command_whowas_from_server
7122 * Added <Client ID> argument to the WHOWAS command reply. Updated
7123 the protocol specs accordingly.
7125 * Implemented WHOWAS command and command_reply to the client
7128 Implemented the WHOWAS printing on the user interface.
7130 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7132 * Added new argument to the WHOWAS command reply, the real name.
7133 It is an optional argument. Updated the protocol specs.
7135 * Added SilcIDCacheDestructor callback that is registered when
7136 the SilcIDCache is allocated. The callback is called when
7137 an cache entry in the ID Cache expires, or is purged from the
7138 cache. Added into lib/silccore/idcache.[ch].
7140 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
7141 to destruct the client entries when the cache entry expires.
7142 Other ID Cache's in server and in the client library ignores
7145 * If the ID Cache entry's `expire' field is zero then the entry
7146 never expires. Added boolean `expire' argument to the
7147 silc_idcache_add function in the lib/silccore/idcache.[ch].
7148 If it is TRUE the default expiry value is used.
7150 * Added silc_server_free_client_data_timeout that is registered
7151 when client disconnects. By default for 5 minutes we preserve
7152 the client entry for history - for WHOWAS command.
7154 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7156 * Added support to the server to enforce that commands are not
7157 executed more than once in 2 seconds. If server receives
7158 commands from client more frequently, timeout is registered
7159 to process the commands. Affected file silcd/command.c.
7160 Added new function silc_server_command_process_timeout.
7162 * Changed NICK_NOTIFY handling in client library to check that
7163 if the client's nickname was changed, so there is no need to
7164 resolve anything from the server.
7166 * Removed error printing from the WHOIS and IDENTIFY commands.
7167 If error occurs then it is ignored silently in the client library.
7168 The application, however, may map the received error to
7169 human readable error string. The application currently maps
7170 the NO_SUCH_NICKNAME error to string.
7172 * Made the command status message public to the application. Moved
7173 them from lib/silcclient/command_reply.c to
7174 lib/silcclient/command_reply.h. The application can map the
7175 received command status to the string with the
7176 silc_client_command_status_message function.
7178 * Added check to the server to check that client's ID is same
7179 as the Source ID in the packet the client sent. They must
7182 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7184 * Added dist-bzip hook to the Makefile.am to make bzip2
7185 compressed distributions.
7187 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7189 * Server now enforces the maximum length for the nickname and
7190 the channel as protocol specification dictates. 128 bytes for
7191 nickname and 256 bytes for channel name.
7193 * Moved the WHOIS printing to the application. The client libary
7194 does not print out the WHOIS information anymore, the application
7195 must do it. Renamed silc_client_command_reply_whois_print to
7196 the silc_client_command_reply_whois_save.
7198 The client's idle time is also sent to the application now, and
7199 the idle is shown on screen.
7201 * Added silc_client_command_reply_identify_save to save the
7202 received IDENTIFY entries.
7204 * Do not check for channel private keys in message sending and
7205 reception if the channel does not have the PRIVKEY mode set.
7206 Affected file lib/silclient/client_channel.c.
7208 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7210 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
7211 just surfaced after chaning the JOIN procedure.
7213 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7215 * Added silc_client_get_clients_by_list to get client entries
7216 from Client ID list, that is returned for example by JOIN
7217 and USERS command replies. The application should use this
7218 function for example when JOIN command reply is received to
7219 resolve the clients already on the channel (library does not
7220 do that anymore as USERS command reply is not used in the JOIN
7221 procedure anymore). Affected files lib/silcclient/silcapi.h and
7222 lib/silcclient/idlist.c.
7224 * JOIN command reply and USERS command reply returns now SilcBuffer
7225 pointers instead of unsigned char pointers when returning
7226 the client list and mode list.
7228 * Added <Client ID> argument to the JOIN command reply, mainly
7229 for the server to identify for which client the command was
7230 originally sent. Updated protocol specs accordingly.
7232 * Added SilcDlist private_key pointer to the SilcChannelEntry
7233 in the client to support the channel private keys. Affected
7234 file is lib/silcclient/idlist.h.
7236 * Added SilcChannelPrivateKey argument to the function
7237 silc_client_send_channel_message so that application can choose
7238 to use specific private ke if it wants to. If it is not provided,
7239 the normal channel key is used, unless private keys are set.
7240 In this case the first (key that was added first) is used
7241 as the encryption key.
7243 * Implemented the support for channel private key handling.
7244 Implemented the following functions:
7246 silc_client_add_channel_private_key,
7247 silc_client_del_channel_private_keys,
7248 silc_client_del_channel_private_key,
7249 silc_client_list_channel_private_keys and
7250 silc_client_free_channel_private_keys
7252 Affected file lib/silcclient/client_channel.c.
7254 * Added the support for the private keys in the channel message
7255 sending and encryption and in the message reception and
7256 decryption. Affected funtions are
7257 silc_client_send_channel_message and silc_client_channel_message.
7259 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7261 * Added SKE's key verify callback to the client library's
7262 KE protocol context. Affected files lib/silcclient/protocol.[ch].
7264 * Removed the statement that server (or router) must send USERS
7265 command reply when joining to the channel so that the client
7266 knows who are on the channel. Instead, the client list and
7267 client's mode list is now sent in the JOIN command reply to the
7268 client who joined channel. This is better solution.
7270 * Added function silc_server_get_users_on_channel and function
7271 silc_server_save_users_on_channel to the silcd/server.[ch].
7273 * Removed function silc_server_command_send_users from the
7276 * Do not show topic on the client library anymore. The topic is
7277 sent in the command reply notify to the application and the
7278 application must show the topic now.
7280 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7282 * Added client searching by nickname hash into the IDENTIFY and
7283 WHOIS commands in the server as they were clearly missing from
7284 them. Affected file is silcd/command.c.
7286 * Fixed a bug in private message receiving in the client library.
7287 The remote ID was freed and it wasn't supposed, now it is
7290 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7292 * Minor fix to the channel payload; allocate the data area, as it
7293 needs to be of specific length.
7295 * If the key agreement port is zero then the operating
7296 system will define the bound port. Affected files are
7297 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7299 * Added new function silc_channel_payload_decrypt into the file
7300 lib/silccore/silcchannel.[ch].
7302 * Moved the channel message etc, check from silc_packet_decrypt
7303 to applications. The library calls now a generic
7304 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7305 when the packet is either normal or special. This was done to
7306 allow more wide range of checking that was not allowed when
7307 the code was in library. Now applications can do virtually any
7308 checks to the packet and return to the library the decision how
7309 the packet should be processed. Affected files are
7310 lib/silccore/silcpacket.[ch].
7312 Added silc_server_packet_decrypt_check to the server and
7313 silc_client_packet_decrypt_check to the client library.
7315 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7316 to send with specified source and destination information.
7318 * Channel message delivery between routers was broken after the
7319 channel key distribution was fixed earlier. The channel key
7320 was used be to distributed to other routers as well which is not
7321 allowed by the protocol. Now this is fixed and channel keys
7322 really are cell specific and the channel message delivery between
7323 routers comply with the protocol specification.
7325 * Fixed various commands in server to check also the global list
7326 for the channel entry and not just the local list. The affected
7327 file silcd/command.c.
7329 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7331 * Added assert()s to buffer formatting and unformatting routines
7332 to assert (if --enable-debug) when error occurs. Affected
7333 file: lib/silcutil/silcbuffmt.c.
7335 * Changed to auto-reconnect to check whether the remote host is
7336 router and register the re-connect timeout if it is. It used
7337 to check that whether we are normal server, but router must do
7338 auto-reconnect with another router as well. Affected file
7341 * Removed the [<key len>] option from CMODE command as the cipher
7342 name decides the key length, nowadays. See the defined ciphers
7343 from the protocol specification.
7345 * Added [<hmac>] option to the CMODE command to define the HMAC
7346 for the channel. Added SILC_CMODE_HMAC channel mode.
7348 * Added [<hmac>] option for the JOIN command so that user can
7349 select which HMAC is used to compute the MACs of the channel
7352 * Added Hmac field to the Channel Message Payload. The integrity
7353 of plaintext channel messages are now protected by computing
7354 MAC of the message and attaching the MAC to the payload. The
7355 MAC is encrypted. Now, it is clear that this causes some
7356 overhead to the size of the packet but rationale for this is that
7357 now the receiver can verify whether the channel message decrypted
7358 correctly and also when private keys are set for the channel the
7359 receiver can decrypt the packet with several keys and check from
7360 the MAC which key decrypted the message correctly.
7362 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7363 lib/silccrypt/silccipher.[ch].
7365 * Added silc_hash_len to return the digest length into the
7366 lib/silcrypt/silchash.[ch].
7368 * Rewrote parts of Silc Channel Payload interface in the
7369 lib/silccore/silcchannel.[ch]. The encode function now also
7370 encrypts the packet and parse function decrypts it.
7372 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7374 * Fixed a minor formatting bug in the SKE's key material processing.
7375 It actually might have processed the keys wrong way resulting
7378 * Redefined the mandatory HMAC algorithms and added new algorithms.
7379 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7380 and hmac-md5 truncated to 96 bits. The mandatory is now
7381 hmac-sha1-96. Rest are optional (including the one that used
7382 to be mandatory). Rationale for this is that the truncated HMAC
7383 length is sufficient from security point of view and can actually
7384 make the attack against the HMAC harder. Also, the truncated
7385 HMAC causes less overhead to the packets. See the RFC2104 for
7388 * Added new [hmac] configuration section. The SKE used to use
7389 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7390 is of course wrong. The official names that must be proposed in
7391 the SKE are the ones defined in the protocol specification
7392 (hmac-sha1-96 for example). The user can configure any hmac
7393 using any hash function configured in the [hash] section. At
7394 least, the mandatory must be configured.
7396 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7398 * Added HMAC list to the SKE proposal list. It has now both
7399 hash algorithm list and HMAC list. This makes the protocol
7400 incompatible with previous versions. The SKE now seems to work
7401 the way it is supposed to work, for the first time actually.
7403 * Defined plain Hash algorithms to the protocol specification.
7406 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7408 * Implemented support for key agreement packets into the server.
7409 Added functions silc_server_key_agreement and
7410 silc_server_send_key_agreement. Other than these functions,
7411 server has nothing to do with this packet.
7413 * Added support for private message key packets into the server.
7414 Added functions silc_server_private_message_key and
7415 silc_server_send_private_message_key.
7419 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7420 called in the protocol's final callback instead in the END
7421 protocol state. This makes a little more sense and in the same
7422 time in client we can use the same protocol routines for normal
7423 key exchange and to key agreement packet handling as well.
7425 * Added to both client's and server's KE protocol context the
7426 SilcSKEKeyMaterial pointer to save the key material. We will
7427 bring the key material to the protocol's final callback by doing
7428 this. The final callback must free the key material.
7430 * Added SKE's packet_send callback into client's KE protocol
7431 context so that the caller can choose what packet sending function
7432 is used. This way we can use different packet sending when
7433 doing normal SKE when doing key agreement packet handling (in
7434 the key agreement packet handling we do not want to encrypt
7437 * Implemented the responder side of the key agreement routines
7438 in the client. The client can now bind to specified port and
7439 accept incoming key negotiation. The key material is passed
7440 to the application after the protocol is over.
7442 * Implemented the processing of incoming Key Agreement packet
7443 in the client. Added function silc_client_key_agreement to
7446 * Implemented the intiator side of the key agreement routines
7447 in the client. The client can now initiate key agreement with
7448 another remote client. The key material is passed to the
7449 application after the protocol is over.
7451 * Created client_keyagr.c to include all the key agreement
7454 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7455 SILC_TASK_CALLBACK except that it is not static.
7457 * Created client_notify.c and moved the Notify packet handling
7458 from the client.[ch] into that file.
7460 * Created client_prvmsg.c and moved all private message and
7461 private message key routines from the client.[ch] into that file.
7463 * Create client_channel.c and moved all channel message and
7464 channel private key routines from the client.[ch] into that file.
7466 * Changed silc_client_get_client_by_id_resolve to resolve with
7467 WHOIS command instead of IDENTIFY command, in the file
7468 lib/silclient/idlist.c.
7470 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7472 * Implemented the SKE's responder side to the Client library.
7474 * When FAILURE is received to the protocol do not trust it
7475 blindly. Register a timeout to wait whether the remote closes
7476 the connection as it should do it, only after that process the
7477 actual failure. This was changed to both client and server.
7479 * Added client_internal.h to include some of the structures
7480 there instead of client.h in lib/silcclient/.
7482 * Added function silc_task_unregister_by_callback to unregister
7483 timeouts by the callback function.
7485 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7487 * Some "Incomplete WHOIS info" errors has been appearing on the
7488 log files. Took away the entry->userinfo check from WHOIS
7489 reply sending. The entry->userinfo is now " " if client did not
7490 provide one. I thought this was fixed earlier but something
7491 is wrong still. Let's see if the error still appears.
7493 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7495 * Fixed a minor bug in the login when the channel key is
7496 re-generated in the server. It used to generate the key in
7497 wrong order and thus caused problems in the channel traffic.
7499 * Fixed a minor bug in channel key distsribution after
7500 KICK command. The key was not sent to the router even though
7503 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7505 * Added silc_ske_process_key_material_data as generic routine
7506 to process any key material as the SILC protocol dictates. The
7507 function is used by the actual SKE library but can be used by
7508 applications as well. This relates to the private message keys
7509 and the channel private keys since they must be processed the
7510 same way the normal SILC session keys. The protocol dictates
7511 this. Affected files: lib/silcske/silcske.[ch].
7513 Added also silc_ske_free_key_material to free the
7514 SilcSKEKeyMaterial structure.
7516 * Defined silc_cipher_set_key function to set the key for
7517 cipher without using the object's method function. The affected
7518 files: lib/silccrypt/silccipher.[ch].
7520 * Implemented silc silc_client_add_private_message_key,
7521 silc_client_add_private_message_key_ske,
7522 silc_client_del_private_message_key,
7523 silc_client_list_private_message_keys and
7524 silc_client_free_private_message_keys functions in the
7527 Added functions silc_client_send_private_message_key to send
7528 the Private Message Key payload and silc_client_private_message_key
7529 to handle incoming Private Message Key payload.
7531 * Added Cipher field to the Private Message Key payload to set
7532 the cipher to be used. If ignored, the default cipher defined
7533 in the SILC protocol (aes-256-cbc) is used.
7535 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7537 * Removed lib/silcclient/ops.h file.
7539 Redefined parts of the SILC Client Library API. Created new
7540 file silcapi.h that deprecates the ops.h file and defines the
7541 published Client Library API. Defined also private message key
7542 API and channel private key API into the file.
7544 This is the file that the application must include from the
7545 SILC Client Library. Other files need not be included by
7546 the application anymore.
7548 * Added new key_agreement client operation callback and also
7549 defined the Key Agreement library API for the application.
7551 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7553 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7554 is used by clients to request key negotiation between another
7555 client in the SILC network. If the negotiation is started it
7556 is performed using the SKE protocol. The result of the
7557 negotiation, the secret key material, can be used for example
7558 as private message key.
7560 Implemented the Key Agreement payload into the files
7561 lib/silccore/silauth.[ch].
7563 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7565 * Redefined ciphers for the SILC protocol. Added some new ciphers
7566 and defined the key lengths for the algorithms. Changed the
7567 code accordingly. The default key length is now 256 bits.
7569 * Fixed SKE key distribution function silc_ske_process_key_material
7570 when the key length is more than 128 bits. The default key
7571 length in SILC is now 256 bits.
7573 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7574 to indicate unsupported algorithm.
7576 * Renamed rijndael.c to aes.c and all functions as well.
7578 * Fixed a long standing channel key setting bug in client library.
7579 Weird that it has never surfaced before.
7581 * Fixed bug in channel deletion. If the entire channel is removed
7582 then it must also delete the references of the channel entry
7583 from the client's channel list as the client's channel entry and
7584 the channel's client entry share same memory.
7586 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7588 * Implemented CONNECT and SHUTDOWN commands in the client.
7590 * Implemented CLOSE command to the client.
7592 * Added the function silc_idlist_find_server_by_name into the
7593 files silcd/idlist.[ch].
7595 Added the function silc_idlist_find_server_by_conn into the
7596 files silcd/idlist.[ch].
7598 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7600 * DIE command was renamed to SHUTDOWN. Updated the both code
7603 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7604 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7606 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7609 * Added function silc_server_create_connection function to create
7610 connection to remote router. My server implementation actually
7611 does not allow router to connect to normal server (it expects
7612 that normal server always initiates the connection to the router)
7613 so the CONNECT command is only good for connecting to another
7616 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7618 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7619 or some other client was kicked from the channel.
7621 Implemented the handling of the notify type to both client
7624 Implemented silc_server_send_notify_kicked to send the KICKED
7625 notify. It is used to send it to the server's primary router.
7627 * Implemented the KICK command into server and client.
7629 * Added `query' argument to the silc_idlist_get_client function
7630 to indicate whether to query the client from server or not if
7633 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7634 to indicate that the client is not channel founder.
7638 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7640 * Removed the rng context from SilcPacketContext structure and
7641 changed that the packet routine uses the Global RNG API.
7643 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7645 * Added support for quit message that client can "leave" on the
7646 channel when it quits the SILC. It is ditributed inside the
7647 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7649 Added silc_server_free_client_data that will take the
7650 signoff message as argument.
7652 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7654 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7656 * Updated parts of the protocol specification to keep it up
7659 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7661 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7662 payloads in one packet.
7664 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7665 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7666 use now the new List flag.
7668 * Also deprecated the following packet types: REPLACE_ID,
7669 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7671 * Added list support for Notify packet in server.
7673 * Added silc_server_send_notify_channel_change to send the
7674 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7675 the silc_server_send_replace_id.
7677 * Added silc_server_send_notify_nick_change to send the
7678 NICK_CHANGE notify type. Deprecates the function
7679 silc_server_send_replace_id.
7681 * Added silc_server_send_notify_join to send the JOIN notify type.
7682 Deprecates the function silc_server_send_new_channel_user.
7684 * Added silc_server_send_notify_leave to send LEAVE notify type.
7685 Deprecates the function silc_server_send_remove_channel_user.
7687 * Added silc_server_send_notify_cmode and
7688 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7689 types. Deprecates the silc_server_send_set_mode function.
7691 * Added SERVER_SIGNOFF notify type to indicate that server has
7692 quit. This means that all clients on the channel from that
7693 server will drop. This can be also used when netsplit happens.
7695 Deprecated REMOVE_ID packet type since it is not needed anymore
7698 Added silc_server_send_notify_server_signoff to send the
7699 SERVER_SIGNOFF notify type. Deprecates the function
7700 silc_server_send_remove_id.
7702 Added also silc_server_send_notify_signoff to send the
7703 SIGNOFF notify type.
7705 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7706 SILC protocol from this day on. Changed the protocol
7707 specification as well.
7709 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7710 notify type. It is used between routers to notify about
7711 topic changes on a channel.
7713 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7716 * Partly updated the protocol specification to comply with the
7717 changes now made. It is still though a bit outdated.
7719 * The JOIN notify type now takes one extra argument <Channel ID>.
7720 The packet used to be destined to the channel but now the
7721 JOIN type may be sent as list thus it is impossible to
7722 destine it to any specific channel. By adding this argument
7723 it is again possible.
7725 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7727 * Added CREDITS file. The CHANGES and CREDITS file will appear
7728 in the distribution as well.
7730 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7732 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7733 types in the server's silcd/packet_receive.c.
7735 * Implemented CMODE and CUMODE to work in router environment.
7737 * Fixed minor encoding and decoding buglet from the
7738 lib/silccore/silcmode.c.
7740 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7743 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7745 * Changed all SilcConfigServer* and silc_config_server* to
7746 SilcServerConfig* and silc_server_config*, respectively.
7749 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7751 * Associated the ID (client or server ID) to the Authentication
7752 Payload to avoid any possibility of forging. Updated the
7753 protocol specification and the code accordingly.
7755 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7757 * The RSA key length is now save to the RsaKey context in the
7758 key generation process in lib/silccrypt/rsa.c. The key length
7759 is now used to figure out the maximum size of the block allowed
7760 to be encrypted/signed.
7762 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7763 is equivalent to the silc_mp_mp2bin but does not allocate any
7766 * Changed silc_mp_mp2bin API to take length argument. If it is
7767 non-zero then the buffer is allocated that large. If zero, then
7768 the size is approximated using silc_mp_sizeinbase, which however
7771 * Created Global RNG API which is global RNG that application can
7772 initialize. After initializing, any routine anywhere in the
7773 code (including library) can use RNG without allocating a new
7774 RNG object. This was done to allow this sort of use of the
7775 RNG in code that has no chance to allocate RNG object. All
7776 applications currently allocate this and many routines in the
7777 library use this. Affected file lib/silccrypt/silcrng.[ch].
7779 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7780 it to use the Global RNG API.
7782 * Defined Authentication Payload into protocol specification that
7783 is used during SILC session to authenticate entities. It is
7784 used for example by client to authenticate itself to the server
7785 to obtain server operator privileges.
7787 Implemented this payload into the lib/silccore/silcauth.[ch].
7788 Implemented also routines for public key based authentication
7789 as the new protocol specification dictates.
7791 Moved definitions of different authentication methods from
7792 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7794 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7795 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7796 silc_pkcs_verify_with_hash functions into the file
7797 lib/silccrypt/silcpkcs.[ch].
7799 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7801 * The client entry's userinfo pointer must be always valid.
7802 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7803 will fail since it requires the userinfo. Now, the userinfo
7804 is allocated as "" if actual userinfo does not exist. Actually,
7805 it must exist and it is totally Ok to drop client connections
7806 that does not announce the userinfo. However, we will make
7807 this workaround for now.
7809 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7810 to return the remote port by socket.
7812 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7814 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7815 SILC_SERVER_PENDING_EXEC and added an new macro
7816 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7817 data or when error occurs while processing the pending command.
7819 Added new argument `destructor' into silc_server_command_pending
7820 and to the SilcServerCommandPending object. This destructor is
7821 now called after calling the pending callback or if error occurs
7822 immediately. If error occurs the actual pending callback won't
7823 be called at all - only the destructor. The destructor may be
7824 NULL if destructor is not needed.
7826 All this applies for client library code as well. Similar
7827 changes were made there as well for the pending commands.
7829 In the client, the application must now allocate the
7830 SilcClientCommandContext with the silc_client_command_alloc
7833 * Added reference counter to the SilcServerCommandContext. Added
7834 function silc_server_command_alloc and silc_server_command_dup
7837 Same type of functions added to the client library for the same
7840 * Removed the cmd_ident from IDListData away since it is now
7841 global for all connections. It is the command identifier used
7842 in command sending and with pending commands. The affected file
7845 * Added reference counter to the SilcSocketConnection objecet to
7846 indicate the usage count of the object. The object won't be
7847 freed untill the reference counter hits zero. Currently only
7848 server uses this, and client ignores it. The client must be
7849 set to use this too later. The affected files are
7850 lib/silccore/silcsockconn.[ch]. Added also the function
7851 silc_socket_dup to increase the reference counter.
7853 This was mainly added because it is possible that the socket
7854 is removed underneath of pending command or other async
7855 operation. Now it won't be free'd and proper DISCONNECTING
7856 flags, etc. can be set to avoid sending data to connection that
7857 is not valid anymore.
7859 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7860 the connection. After that it sets SILC_SET_DISCONNECTED.
7861 It is, however, possible that the socket data is not still freed.
7862 The silc_server_packet_process now checks that data is not
7863 read or written to connection that is DISCONNECTED. The socket
7864 get's freed when the reference counter hits zero.
7866 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7868 * Changed the client operation API: channel_message operation's
7869 `sender' is now the client entry of the sender, not the nickname
7870 and the `channel' is the channel entry, not the channel name.
7872 In the private_message operation the `sender' is now also the
7873 client entry of the sender not the nickname.
7875 Affected file is lib/silcclient/ops.h and all applications
7876 using the client operations.
7878 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7880 * Moved the calling of ops->connect() from connect_to_server_final
7881 into receive_new_id functin since that is the point when the
7882 client is actually allowed to send traffic to network. The
7883 affected file is lib/silcclient/client.c.
7885 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7887 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7888 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7889 (if needs broadcasting) instead of broadcasting the packets one
7890 by one which would make a burst in the network traffic.
7892 * Added `broadcast' argument to the functions in silcd/server.[ch]
7893 silc_server_create_new_channel[_with_id] to indicate whether
7894 to send New Channel packet to primary router.
7896 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7898 * Added new function into the silcd/server.[ch] files:
7899 silc_server_create_new_channel_with_id to create new channel with
7900 already existing Channel ID.
7902 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7903 lib/silccore/silcpacket.h. This packet is used t send list of
7904 Set Mode payloads inside one packet. Server uses this to set
7905 the modes for the channels and clients on those channels, that it
7906 announced to the router when it connected to it. The protocol
7907 specification has been updated accordingly.
7909 * The silc_server_new_channel did not handle the packet coming
7910 from normal server as it normally does not send that. However,
7911 when it announces its channels it does send it. Implemented
7912 the support for that.
7914 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7915 into the file lib/silccore/id.h.
7917 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7919 * Fixed memory leaks in the functions silc_idlist_del_client,
7920 silc_idlist_del_channel and silc_idlist_del_server in the file
7921 silcd/idlist.c. All of those leaked like a sieve.
7923 * Fixed some small memory leaks in the client's function
7924 silc_client_notify_by_server.
7926 * Added functions into silcd/server.c: silc_server_announce_clients,
7927 silc_server_announce_channels and silc_server_announce_server.
7928 These functions are used by normal and router server to announce
7929 to its primary router about clients, channels and servers (when
7930 router) that we own. This is done after we've connected to the
7933 These functions effectively implements the following packet types:
7934 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7935 and SILC_PACKET_NEW_ID_LIST.
7937 * Added new functions into the silcd/packet_receive.[ch]:
7938 silc_server_new_id_list, silc_server_new_channel_list and
7939 silc_server_new_channel_user_list to handle the incoming
7940 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7942 * Added support of changing Channel ID in the function
7943 silc_server_replace_id. If the server that announces a channel
7944 to the router already exists in the router (with same name but
7945 with different Channel ID), router is responsible to send
7946 Replace ID packet to the server and force the server to change
7947 the Channel ID to the one router has.
7949 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7950 client that the Channel ID has been changed by the router. The
7951 normal server sends this to the client. Client must start using
7952 the new Channel ID as the channel's ID.
7954 Implemented handling of this new type into lib/silcclient/client.c
7955 into the function silc_client_notify_by_server.
7957 * Added new function silc_idlist_replace_channel_id into the files
7958 silcd/idlist.[ch] to replace the Channel ID.
7960 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7962 * Call silc_server_command_identify_check always when processing
7963 the IDENTIFY command in silcd/command.c
7965 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7967 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7968 send keepalive packets. The packet can be sent by clients,
7969 servers and routers.
7971 Added function silc_socket_set_heartbeat into the file
7972 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7973 If not set, the heartbeat is not performed. The actual
7974 heartbeat is implemented in the low level socket connection
7975 library. However, application is responsible of actually
7978 Added silc_server_send_heartbeat to send the actual heartbeat
7979 packet into silcd/packet_send.[ch]. Server now performs
7980 keepalive with all connections.
7982 * Added silc_task_get_first function into lib/silcutil/silctask.c
7983 to return the timeout task with shortest timeout. There was a bug
7984 in task unregistration that caused problems. TODO has been
7985 updated to include that task system must be rewritten.
7987 * The client library will now resolve the client information when
7988 receiving JOIN notify from server for client that we know but
7989 have incomplete information.
7991 * Rewrote parts of silc_server_remove_from_channels and
7992 silc_server_remove_from_one_channel as they did not remove the
7993 channel in some circumstances even though they should've.
7995 * Encryption problem encountered in server:
7997 The LEAVE command used to send the Channel Key packet to the
7998 router immediately after generating it. However, the code
7999 had earlier sent Remove Channel user packet but not immediately,
8000 ie. it was put to queue. The order of packets in the router
8001 was that Channel Key packet was first and Remove Channel User
8002 packet was second, even though they were encrypted in the
8003 reverse order. For this reason, MAC check failed. Now, this
8004 is fixed by not sending the Channel Key packet immediately but
8005 putting it to queue. However, this is more fundamental problem:
8006 packets that are in queue should actually not be encrypted
8007 because packets that are sent immediately gets encrypted
8008 actually with wrong IV (and thus MAC check fails). So, packets
8009 that are in queue should be encrypted when they are sent to
8010 the wire and not when they put to the queue.
8012 However, the problem is that the current system has not been
8013 designed to work that way. Instead, the packet is encrypted
8014 as soon as possible and left to the queue. The queue is then
8015 just purged into wire. There won't be any fixes for this
8016 any time soon. So, the current semantic for packet sending
8019 o If you send packet to remote host and do not force the send
8020 (the packet will be in queue) then all subsequent packets to the
8021 same remote host must also be put to the queue. Only after the
8022 queue has been purged is it safe again to force the packet
8025 o If you send all packets immediately then it safe to send
8026 any of subsequent packets through the queue, however, after
8027 the first packet is put to queue then any subsequent packets
8028 must also be put to the queue.
8030 Follow these rules and everything works fine.
8032 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8034 * Added new function silc_server_remove_clients_by_server to
8035 remove all client entries from ID list when the server connection
8036 is lost. In this case it is also important to invalidate all
8037 client entires as they hold the invalid server entry. This
8038 fixes fatal bug when server has lost connection and will reconnect
8041 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8043 * Made some sanity checks to silc_server_daemonise like to check
8044 whether the requested user and group actually exists.
8046 * Added sanity check to SKE's silc_ske_responder_finish to check
8047 that the public and private key actually is valid.
8049 * Invalidate the client's nickname when receiving Replace ID
8050 packet and the Client ID is being replaced. This means that the
8051 server will query the nickname if someone needs it (client)
8054 * Sort the ID Cache in client library when the ID Cache data
8055 has changed (needs sorting).
8057 * Do not allow for SILC client to create several connections to
8058 several servers. The client does not support windows right now
8059 and generating multiple connections causes weird behaviour.
8061 Irssi-silc client does support windows and can handle several
8062 connections without problems, see: www.irssi.org and SILC plugin.
8064 * Fixed some places where client was added to the IDList. The
8065 rule of thumb is following (in order to get everything right):
8066 If the client is directly connected local client then the
8067 `connection' argument must be set and `router' argument must be
8068 NULL to silc_idlist_add_client function. If the client is not
8069 directly connected client then the `router' argument must
8070 bet set and the `connection' argument must be NULL to the
8071 silc_idlist_add_client function.
8073 * The funtion silc_server_packet_send_local_channel actually did
8074 not check whether the client was locally connected or not. It
8075 does that now. Fixed a bug related to LEAVE command.
8077 * Fixed Remove Channel User payload parsing bug in server's
8078 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
8080 * The server's silc_server_save_channel_key now checks also the
8081 global ID list for the channel as it might not be in the local
8082 list. Fixed a bug related to LEAVE command.
8084 * Is this the end of the [<unknown>] buglet that has been lurking
8085 around for a long time? A little for loop fix in server's
8086 silc_server_command_whois_parse that is used by both IDENTIFY
8087 and WHOIS command. At least, this was a clear bug and a cause
8088 of one type of [<unknown>] buglet.
8090 * WHOIS and IDENTIFY commands call the function
8091 silc_server_command_[whois/identify]_check function even if
8092 we are not router server.
8094 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8096 * Added --with-gmp configuration option. If set the GMP
8097 is always compiled in the SILC source tree. If not set then
8098 it is checked whether the system has the GMP3 installed. If
8099 it has then the GMP won't be compiled (the system's headers
8100 and library is used), if it doesn't have it then the GMP is
8101 compiled in the SILC source tree.
8103 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8105 * Changed RSA private exponent generation to what PKCS #1
8106 suggests. We try to find the smallest possible d by doing
8107 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
8108 not security fix but optimization.
8110 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8112 * Added new config entry [Identity] to fork the server and run
8113 it as specific user and group. A patch from Bostik.
8115 * Imported Dotconf configuration library into lib/dotconf.
8116 This will be used to create the SILC configuration files later.
8117 It will appear in the distsribution after this commit.
8119 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8121 * A big code auditing weekend happening. Auditing code for
8122 obvious mistakes, bugs and errors. Also, removing any code
8125 Removed files for being obsolete:
8127 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
8128 inline in the file lib/silcutil/silcbuffer.h)
8130 o lib/silcutil/silcbufutil.c (the header has inline versions)
8132 Changed code to fix possible error conditions:
8134 o The buffer formatting routines now check that the destination
8135 buffer really has enough space to add the data. This applies for
8136 both buffer formatting and unformatting
8137 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
8138 unformatting was changed to accomodate following rules:
8139 XXX_*STRING_ALLOC will allocate space for the data into the pointer
8140 sent to the function while XXX_*STRING will not allocate or copy
8141 the data into the buffer. Instead it sets the pointer from the
8142 buffer into the pointer sent as argument (XXX_*STRING used to
8143 require that the pointer must be allocated already). This change
8144 makes this whole thing a bit more consistent and more optimized
8145 (note that the data returned in the unformatting with XXX_*STRING
8146 must not be freed now). The routines return now -1 on error.
8148 o Tried to find all code that use buffer_format and buffer_unformat
8149 and added return value checking to prevent formatting and
8150 especially unformatting errors and possible subsequent fatal
8153 o Changed ske->x and ske->KEY to mallocated pointers in
8154 lib/silcske/silcske.h. Fixed possible data and memory leak.
8156 o Added return value checking to all *_parse* functions. Fixed
8157 many memory leaks as well.
8159 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
8160 so that buffer overflows would not happen. All code now also
8161 checks the return value as it can fail.
8163 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8165 * Added reconnection support to server if the normal server looses
8166 its connection to the router (for example if router is rebooted).
8167 The server performs normal reconnection strategy implemented
8168 to the server. Affected file silcd/server.c.
8170 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8172 * Added new packet type SILC_PACKET_SET_MODE that is used to
8173 distribute the information about changed modes (for clients,
8174 channels and clients channel modes) to all routers in the
8175 network. Updated the protocol specification accordingly.
8177 Added functions into silcd/packet_send.c and
8178 silcd/packet_receive.c: silc_server_send_set_mode,
8179 silc_server_set_mode.
8181 Added new files silcmode.[ch] into lib/silccore that implements
8182 the encoding and decoding of Set Mode Payload. Added new type
8183 SilcSetModePayload. Moved the definitions of different modes
8184 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
8186 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8188 * Oops, a little mistake in server's connection authentication
8189 protocol. The protocol is not ended with FAILURE but with
8190 SUCCESS if the authentication is Ok. :) Affected file is
8193 * Implemented NICK_CHANGE notify handling in server in the file
8194 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
8195 the local clients on the channel. After the changing nickname
8196 in router environment snhould work and the [<unknown>] nickname
8197 should appear no more.
8199 The silc_server_replace_id function that receives the Replace ID
8200 payload now sends the NICK_CHANGE notify type also in the file
8201 silcd/packet_receive.c
8203 * Changed WHOIS and IDENTIFY command to support the maximum amount
8204 of arguments defined in protocol specs (3328 arguments). This
8205 fixed a bug that caused problems when there were more than three
8208 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8210 * Added extra parameter, command identifier, to the
8211 silc_client_send_command so that explicit command identifier
8214 Changed that ID list routines uses specific command identifier
8215 when sending WHOIS/IDENTIFY requests to the server so that they
8216 can be identified when the reply comes back.
8218 Affected files lib/silcclient/command.[ch],
8219 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
8221 * Added `sender' argument to silc_server_packet_send_to_channel
8222 to indicaet the sender who originally sent the packet to us
8223 that we are now re-sending. Ignored if NULL. Affected file
8224 silcd/packet_send.[ch].
8226 * Added some server statistics support in silcd/server_internal.h
8227 SilcServerStatistics structure and around the server code. Also
8228 send some nice statistics information when client is connecting
8231 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8233 * Fixed channel ID decoding in server's JOIN command reply in
8234 silcd/command_reply.c
8236 * Fixed braodcasting of replace ID payload to not to send it if
8237 we are standalone server in silcd/packet_receive.c.
8239 * Fixed all channel message sending routines to not to send
8240 packets to clients that has router set, since they are routed
8241 separately in the same function earlier. Affects file
8242 silcd/packet_send.c and all channel packet sending functions.
8244 * In USERS reply, res_argv[i] are not allocated, the table
8245 is allocated. Thus changed that free the table, not its
8248 * In server's whois_check and identify_check if the client is
8249 locally connected do not send any WHOIS commands - they are not
8252 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8254 * Fixed some minor bugs in client when sending WHOIS command. The
8255 arguments was in wrong order.
8257 * Removed statis function add_to_channel from server in
8258 silcd/command.c that was previously used with the joining but
8261 * Tested USERS command in router environment successfully with two
8262 routers, two servers and two clients.
8264 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8266 * Reorganized the USERS command and command reply in client library
8267 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
8268 When the command is given by user we register a pending command
8269 callback that will reprocess the command after the reply has been
8270 received from the server. When reprocessing the packet we then
8271 display the information. Thus, the USERS information is displayed
8272 now in the command callback instead of in the command reply
8273 callback. The processing of the command is same as previously
8274 when server has sent the command reply in the JOINing process.
8276 * Added to USERS command in silcd/command_reply.c to join the client,
8277 we didn't use to know about, to the channel after we've created
8278 a client entry for it. Also, for clienet we did know already still
8279 check whether it is on the channel or not and add it if not.
8281 * Removed silc_server_command_join_notify as the function and its
8284 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8286 * Changed the client's pending command handling to the same as the
8287 server's pending command handling. It is also now possible to
8288 execute command reply functions from other command reply
8289 function as the function callbacks for commands and command
8290 replies are one and same. The pending commands are not static
8291 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8292 in client connection context. Thus, pending commands are server
8293 connection specific as it is convenient.
8295 Changed the function silc_client_command_pending and
8296 silc_client_command_pending_del and added new function
8297 silc_client_command_pending_check. Removed the
8298 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8301 * Added cmd_ident, current command identifier, to the client
8302 connection context in lib/silcclient/client.h to keep track on
8303 command identifiers used in command sending. Client's command reply
8304 function handling now supports the mandatory command identifiers.
8306 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8307 funtions in client to fully support pending command callbacks.
8309 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8310 as one of the arguments to the application in the command reply
8313 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8314 before first releasing SILC but came back. Now it is removed again
8315 and should come back nomore. The FORWARDED flag was used only
8316 by the JOINing procedure by forwarding the command packet to router.
8317 Now, the JOINing procedure has been changed to more generic (due
8318 to various router environment issues) and FORWARDED is not needed
8319 anymore for anything. The protocol specification is yet to be
8322 Now, removed silc_server_packet_forward from server and the flag
8323 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8325 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8327 * Renamed NAMES command to USERS command. The NAMES was named that
8328 due to historical reasons. Now it is renamed. Also, rewrote
8329 parts of the USERS command. The nickname list is not sent anymore
8330 by the server. Only Client ID and mode lists are sent in the USERS
8331 command. Changed this also to the protocol specification.
8333 The client now resolves the names and stuff after it receives
8334 the USERS list from the server when joining to the channel.
8336 * WHOIS and IDENTIFY commands has been changed to support multiple
8337 Client ID's per command. One can now search for multiple users
8338 in the network by sending only one WHOIS or IDENTIFY command.
8339 Changed the code and the protocol specifications.
8341 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8342 uses silc_server_command_whois_parse to parse the request. */
8344 * If normal server, do not parse the WHOIS and IDENTIFY requests
8345 before sending it to the router. Saves some time.
8347 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8349 * Fixed JOIN command on client library. Wrong number of arguments
8350 used to crash the client.
8352 * Added silc_server_channel_has_global function to check whether
8353 channel has global users or not.
8355 * Added silc_server_channel_has_local function to check whether channel
8356 has locally connected clients on the channel.
8358 * The silc_server_remove_from_one_channel now checks whether the
8359 channel has global users or not after given client was removed from
8360 the channel. It also checks whether the channel has local clients
8361 on the channel anymore. If it does not have then the channel entry
8362 is removed as it is not needed anymore.
8364 * The silc_server_notify now checks on JOIN notify whether the joining
8365 client is one of locally connected or global. If it is global then
8366 the channel has now global users on the channel and that is marked
8367 to the channel entry. Also, it now saves the global client to
8368 global list who is joining and JOINs it to the channel. This is
8369 for normal server, that is.
8371 Changed silc_server_send_notify_on_channel,
8372 silc_server_packet_relay_to_channel and
8373 silc_server_packet_send_to_channel check if we are normal server
8374 and client has router set (ie. global client) do not send the
8375 message to that client, as it is already routed to our router.
8377 * Implemented LEAVE notify type handling in silc_server_notify
8380 * Tested LEAVE command in router environment successfully. Tested
8381 with two routers, two servers and two clients.
8385 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8387 * Implemented SIGNOFF notify type handling in silc_server_notify
8390 * silc_server_remove_id now removes the client entry from all channels
8391 it has joined and thusly sends SIGNOFF notify type.
8393 * Rewrote the NAMES list generation in server by removing two excess
8394 loops. The lists are created now inside one loop.
8396 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8398 * silc_server_remove_channel_user checks now also global list
8399 for channel and client.
8401 * silc_server_new_channel_user checks now both local and global
8402 list for channel and client. Fixed a bug in client id decoding.
8403 Used to decode wrong buffer.
8405 * silc_server_channel_message checks now both local and global
8406 list for channel entry.
8408 * Tested channel joining (hence JOIN) in router environment
8409 successfully. Tested with two routers, two servers and two
8412 * Tested channel message sending in router environment successfully.
8414 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8416 * Added silc_server_save_channel_key into server.[ch] to save the
8417 received channel key in Channel Key payload processing. It is
8418 also used in JOIN command reply handling.
8420 Equivalent function silc_client_save_channel_key added into
8421 client.[ch] into client library.
8423 * Changed JOIN command reply to send information whether the channel
8424 was created or not (is existing already) and the channel key
8425 payload. Changed protocol specs accordingly.
8427 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8428 the request was sent by ID and not by nickname. Crashed on
8431 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8433 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8434 now correctly save the received data.
8436 * silc_server_free_sock_user_data now notifies routers in the
8437 network about entities leaving the network.
8439 At the same time implemented functions silc_server_remove_id
8440 and silc_server_send_remove_id to receive and send REMOVE_ID
8441 packets. The packet is used to notify routers in the network
8442 about leaving entities. The ID removed will become invalid in
8445 * Added function silc_idlist_del_server into server. Removes and
8446 free's server entry from ID list.
8448 * silc_server_private_message function now checks, if we are router,
8449 that the destination ID really is valid ID, naturally.
8451 * In router when NEW_ID packet is received (for new client) the
8452 hash of the Client ID is saved in the ID Cache but the
8453 client->nickname is set to NULL, instead of putting the hash
8456 IDENTIFY command now also checks that client->nickname must be
8457 valid. If it is not if will request the data from the server who
8458 owns the client. Added new function
8459 silc_server_command_identify_check.
8461 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8462 to set the command to already allocated Command Payload.
8464 * Tested private message sending in router environment with two
8465 routers, two servers and two clients. Fixed minor bugs and now
8468 * Fixed segfault from client's NAMES command. Used to crash if
8471 * Forwarded packets must not be routed even if it is not destined
8472 to the receiver. Changed server code comply with this.
8474 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8476 * Added `require_reverse_mapping' boolean value to ServerParams
8477 structure. If TRUE (not default) the server will require that
8478 the connecting host has fully qualified domain name.
8480 If the reverse mapping is not required and hostname could not be
8481 found the IP address is used as hostname.
8483 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8485 * Implemented version string checking to both client and server.
8486 The check is incomplete currently due to the abnormal version
8487 strings used in development version of SILC.
8489 * Changed all command functions in server to use the new
8492 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8494 * Changed char *data to unsigned char *data in ID Cache system to
8495 support binary data as ID Cache data. Changed code to support
8496 binary data in lib/silccore/idcache.c.
8498 * Renamed silc_server_packet_relay_command_reply to
8499 silc_server_command_reply as it is normal packet receiving
8500 function. Rewrote the function to accept command replys for
8501 servers and not only for clients.
8503 * Mark remote router always as registered server if we are connecting
8504 to it. Otherwise, commands sent by the router to us are ignored.
8506 * All ID List find routines now returns the ID Cache Entry pointer
8507 as well if requested.
8509 * WHOIS command works now in router environment, tested with two
8510 routers, two servers and two clients.
8512 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8513 in router environment (as it is almost equivalent to WHOIS) but
8514 hasn't been tested thoroughly. Added new functions:
8516 silc_server_command_identify_parse
8517 silc_server_command_identify_send_reply
8518 silc_server_command_identify_from_client
8519 silc_server_command_identify_from_server
8521 * Disabled route cache adding because adding two different ID's with
8522 same IP replaces the old cache entry thus giving wrong route.
8523 The entry->router->connection is always the fastest route anyway
8524 so route cache may not be needed. Of course, new routes maybe
8525 established after receiving the ID when the entry->router->connection
8526 might not be anymore the most optimal.
8528 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8530 * Add route cache for received ID for fast routing.
8532 * Added silc_server_packet_route to route received packet on router
8533 that is not destined to us.
8535 * Renamed silc_server_get_route to silc_server_route_get.
8537 * Added id_string and id_string_len fields into SilcServer to
8538 include encoded ServerID for fast comparing without excess
8539 encoding of the ID's.
8541 * Cleaned up WHOIS command on server side. Added following static
8544 silc_server_command_whois_parse
8545 silc_server_command_whois_check
8546 silc_server_command_whois_send_reply
8547 silc_server_command_whois_from_client
8548 silc_server_command_whois_from_server
8550 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8551 arguments in command replies. All command functions should be
8552 updated to use this macro.
8554 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8556 * Minor typo fixes on command reply handling on server.
8558 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8560 * Added silc_server_command_add_to_channel internal routine to add
8561 the client to the channel after router has created the channel and
8562 sent command reply to the server.
8564 * Added generic silc_server_send_command to send any command from
8567 * Use static buffer with ID rendering instead of duplicating data.
8569 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8571 * Fixed a channel user mode bug when joining to a channel server gave
8572 everybody channel founder rights, oops.
8574 * We mark ourselves as the router of the incoming server connection
8575 if we are router ourselves. This way we can check in some packet
8576 sending functions whether it is locally connected server. For
8577 incoming router connections we put NULL.
8579 * For router sending packets locally means now always sending the
8580 packet cell wide; to local clients and local servers. For normal
8581 server sending packet locally means sending it to only local
8584 * Fixed the JOIN command to really work in router environment. If the
8585 channel is created it is always created by the router. Router is
8586 also responsible of making the initial joining to the channel,
8587 sending JOIN notify to the sending server and distributing
8588 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8589 does not exist server doesn't do anything else but forward the
8590 command to the router which performs everything.
8592 * Added silc_server_send_channel_key function to send the Channel Key
8595 * Added silc_server_create_channel_key to create new channel key. The
8596 channel key is now re-generated everytime someone joins or leaves
8597 a channel, as protocol dictates. Note: channel->key_len is the
8600 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8602 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8603 packet_receive.[ch] to separate packet sending and receiving
8604 routines. The server.[ch] now includes everything else including
8605 actual packet processing (writing and reading data) and other
8608 Renamed silc_server_private_message_send_internal to
8609 silc_server_send_private_message. The routine is still though
8610 used only to relay private messages as server does not send
8611 private messages itself.
8613 Renamed silc_server_new_channel to silc_server_create_new_channel
8614 and added new function sicl_server_new_channel that handles the
8615 incoming New Channel packet. Added also new sending function
8616 silc_server_send_new_channel to send New Channel Payload.
8618 * Added new function silc_server_notify to process incoming notify
8619 packet to the server/router. Server may then relay the notify
8620 to clients if needed.
8622 * Added new function silc_server_new_channel_user to process incoming
8623 New Channel User packet. Router will redistribute the packet and
8624 send JOIN notify to its local clients and locally connected servers
8625 if needed. Normal server will send JOIN notify to its local client
8626 on same channel when received this packet. Added also corresponding
8627 sending function silc_server_send_new_channel_user to sent the
8630 * Added boolean route argument to send_notif_to_channel and
8631 packet_send_to_channel functions to attempt to route the packet
8632 if it is TRUE and send only locally if it is FALSE.
8634 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8636 * silc_server_replace_id now broadcasts the received replace ID
8637 packet if it is not broadcast packet already. The router must
8638 broadcast to inform other routers about changed ID.
8640 * Added backpointer to server's router into SilcServer context in
8641 silcd/server_internal.h.
8643 * Fixed silc_server_packet_broadcast to send correct broadcast
8646 * The channel key is now distributed to the local client as soon
8647 as it is received from the router (in router environment) so that
8648 no other packet may be sent for the channel until client has
8651 * silc_server_remove_channel_user now broadcasts the received
8652 Remove Channel User packet if it is not broadcast packet already.
8653 The router must broadcast to inform other routers about removed
8656 * Added users field into SilcPacketContext that is a reference count
8657 of the context. One can increase the reference count by calling
8658 silc_packet_context_dup which is now changed to just increase the
8659 reference count instead of duplicating the data. The reference
8660 count is decresed by calling silc_packet_context_free that will
8661 free the data after the reference count hits zero.
8663 For now on the packet context and everything allocated into it
8664 (including the raw packet from network) must be freed by calling
8665 the new silc_packet_context_free function. Added also new function
8666 silc_packet_context_alloc that must be used now to allocate the
8667 context. This also means that if a routine is asynchronous from
8668 silc_[client/server]_packet_parse_type the packet context must
8669 be duplicated by calling silc_packet_context_dup. Otherwise it
8670 gets free'd after silc_[client/server]_packet_parse_type returns.
8671 Also, one must remember that if packet is duplicated then its
8672 reference count must be decresed by calling the free function as
8673 many times as it was duplicated.
8675 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8676 from both client and server.
8678 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8680 * Made joining to a channel working in router environment.
8682 * Cleaned up JOIN command on server side and create function
8683 silc_server_command_join_channel internal routine to make the
8686 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8688 * Changed silc_command_pending list to SilcDList. Also, added
8689 `ident' field to SilcServerCommandPending structure to identify
8690 the reply and to call correct callback.
8692 Added silc_server_command_pending_check function to replace the
8693 corresnponding macro. The silc_command_pending list is not
8696 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8697 to set identifier to previously allocated Command Payload. It
8698 is used to set identifier for command when resending Command
8701 * Added silc_command_payload_encode_payload to encode Command
8702 Payload buffer from SilcCommandPayload structure.
8704 * Added silc_argument_payload_encode_payload to encode Argument
8705 payload buffer from SilcArgumentPayload structure.
8707 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8709 * Changed WHOIS command to support router connection on server side.
8710 The whois request is always sent to router unless the server is
8711 standalone server. After server has received the reply from the
8712 router will it send the reply to the client.
8714 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8715 broadcast received broadcast packet. The function is used only
8716 by router. The broadcast packet is always sent to the router's
8719 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8720 render given ID to printable string, for log files for example.
8722 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8724 * Made basic router to router connections working. At least they
8725 can now connect to each other but nothing really works the way
8726 they are supposed - yet.
8728 * Added new initiator token to RouterConnection configuration
8729 file in silcd/serverconfig.[ch]. It is used to tell whether we
8730 are the initiator to the remote router or whether we'll expect
8731 the other end to connect.
8733 * Moved registering of listener task to silc_server_init, hence
8734 the server starts listenning as soon as it is run, even if it
8735 does not have connections to other routers. Let's see how well
8738 * Changed default connection retry timeouts for more suitable in
8741 * Removed cipher and such arguments from silc_idlist_add_client
8742 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8743 Added new function silc_idlist_add_data to add the keys and stuff
8746 * Added SilcIDListData structure and added it to SilcClientEntry
8747 and SilcServerEntry as their first field in the structure. This
8748 way we can explicitly cast the ID entries to the SilcIDListData
8749 structure and get common data for the entries. In past, we had
8750 to first check what type of connection it is and then cast it to
8751 correct ID entry type. Now, we can directly cast the opaque
8752 pointer to the SilcIDListData (no matter what ID entry it actually
8753 is) and get the data needed.
8755 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8757 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8758 in some circumstances even if threre were timeout tasks, though not
8759 IO tasks, but tasks anyway. Now fixed.
8761 * Defined SilcServerConnection structure to hold connection specific
8762 stuff about directly connected servers and routers. The definition
8763 is currently in silcd/server_internal.h. I thought about having
8764 a bit more important role fro this struct but for now it is used
8765 only when connecting to other server (or router actually).
8767 * Added connecting retry support in server when connecting to
8768 router(s). The retry feature implement exponential backoff
8769 algorithm. Also, added SilcServerParams structure to hold default
8770 parameters for server. For now, it include these retry settings
8771 and are hard coded. After server is moded to be as Silc Server
8772 Library this structure will be more important.
8774 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8776 * Changed client librarys channel->clients table to SilcList and
8777 changed code accordingly.
8779 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8781 * Changed client's channel table to SilcList and changed code
8782 accordingly. Also changed SilcChannelClientEntry to include back-
8783 pointer to the channel so that client entry can use that structure
8784 as list as well and we have fast cross-reference to the channel.
8785 This change dramatically decreased the complexity of channel
8786 handling with client entry and vice versa (removed one extra
8787 loop when searching for channel entry from many functions).
8789 * Changed server->sim from table to SilcDList and changed code
8792 * NAMES command can now be used from user interface. It will show
8793 the user list on the channel, neatly.
8795 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8796 Code now saves realname of the user if it becomes available.
8798 * Renamed configure.in to configure.in.pre and made ./prepare
8799 script to automatically add correct version string to
8800 configure.in which it creates from configure.in.pre.
8802 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8804 * NAMES command reply now shows users mode with the nickname when
8807 * Moved silc_client_ch[u]mode[_char] functions from
8808 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8809 place sucks, they are utility functions and should be in some
8812 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8814 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8817 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8821 * Added TRQ (efficient deque and list library) into lib/trq. This is
8822 a very good list library that is currently used in the SILC. Defined
8823 SilcList API over the library because I didn't like the API very
8824 much. See lib/trq/silclist.h for the API and examples of how to
8825 use the API. Fixed various places in the code to use the new
8826 SilcList API. The SilcList is meant for lists that has a structure
8827 already defined as a list. It is not suitable to add just some
8828 context to the list (in TRQ, the context is the list actually).
8830 So, I defined SilcDList that can be used for the purpose where
8831 predefined list structure does not exit. This can be used as
8832 such list. Now some context just can be added to the SilcDList.
8833 Currently this list is not used in the SILC just yet, though there
8834 are a lot places where this can replace dynamically allocated
8835 tables and I will fix these places, later, to use SilcDList.
8836 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8837 and use TRQ internally).
8839 Also fixed some annoying warning messages that the original TRQ
8840 code generated. Also minor changes to TRQ's Makefile.in.
8842 * Added support for querying by Client ID to both WHOIS and
8843 IDENTIFY commands into server, as required by the protocol.
8845 * Removed method function pointers from SilcBuffer structure. They
8846 weren't used to anything and just increased the context size for
8847 no good reason. This change also made silc_buffer_alloc and
8848 silc_buffer_free functions inline functions.
8850 * Disabled command flooding detection support until it's fixed so
8851 that it accepts commands in but does not execute them more than once
8854 * Added silc_net_localhost(), to return local hostname, into
8855 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8856 that must be initialized before calling silc_client_init.
8858 * Added new function: silc_server_send_notify_on_channels to send
8859 notify messages to all channels client has joined. It is assured
8860 that the message is sent only once per client.
8862 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8863 lib/silcutil/silcutil.[ch] as silc_format function. The new
8864 function is generic and is used by server as well, not only by
8865 the logging routines.
8867 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8868 the provided version string was not acceptable. Added new function:
8869 silc_ske_check_version into lib/silcske/silcske.h. The function
8870 must be implemented by the application (client or server) and it
8871 does not reside in the SKE library. The function checks the version
8872 string remote end sent.
8874 * Added back pointers (to opaque context and to SilcSocketConnection)
8875 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8877 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8878 duplicate packet context structure.
8880 * Changed `notify' client operation to send same arguments as client
8881 receives from server except for ID's. ID's are mapped to correct
8882 ID entry and that is returned. Also, if channel entry is not sent
8883 by server but the notify is for channel the channel entry is sent
8884 to application (otherwise application doesn't know that it is for
8885 channel (library gets it from packet's Destination ID)).
8887 * Added silc_client_remove_from_channels into client library to
8888 remove a client from all channels it has joined to. Used when
8889 received SIGNOFF notify from server. Added also new function
8890 silc_client_replace_from_channels to replace old ID entry with
8891 new ID entry on all channels. Used when received NICK_CHANGE
8894 * Fixed ID Cache list handling in silc_idlist_get_client in
8895 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8896 to get (or query) client by ID.
8898 * Updated TODO list.
8900 * Added connection authentication status message defined by the
8901 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8902 support for these into the code in client and server side.
8904 * Added generic function silc_client_send_command to send any command
8905 with variable argument list. Application should use this function
8906 to send commands if the command functions provided by the library
8907 does not suite for the application's user interface needs.
8909 * Added new `failure' client operation. Application is notified about
8910 received failure packet if client is executing a protocol. In this
8911 case the protocol's execution has failed.
8913 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8914 is required by the protocol.
8916 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8917 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8920 * Added status flag to SilcSKE object to indicate realtime status
8921 of the SKE protocol.
8923 * Application receives now exactly same command reply arguments as
8924 the library receives from server. However, if ID is received the
8925 corresponding ID entry is returned to the application (eg. Client
8926 ID is mapped to correct SilcClientEntry entry and that is returned).
8927 Changed command_reply client operation due to this change.
8929 * Changed all ID's in commands and in command replys as ID Payloads.
8930 Change affected both client and server side codes.
8932 All ID's sent in SILC network (with execption of ID's in SILC
8933 Packet header) are sent in ID Payload to support variable length
8936 * Server now notifies nick changes and notifies all clients on
8937 the channels about the new nickname (about the new Client ID,
8940 * Implemented CMODE command to change channel modes. Supports all
8941 channel modes defined by the protocol specs except ban and invite
8942 lists. (Also, private channel key mode is supported but support for
8943 setting private channel key in client is missing, thus, this mode
8944 has no effect on client side (except that server requires that the
8945 client uses private channel key and normal channel traffic does not
8948 Also, invite mode works per se, but INVITE command does not work
8949 yet correctly, so you can set channel as invite only channel but
8950 inviting clients to the channel does not work (it is yet to be
8951 thought what's the best way to do it).
8953 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8954 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8955 Implemented CUMODE command to change user's mode on the channel.
8956 Supports all modes defined by the protocol specs.
8958 * Added NAMES command reply to return users modes on the channel.
8960 * Removed unnecessary and slow ciphers from lib/silccrypt.
8962 * Set SO_KEEPALIVE option to connection sockets by default.
8964 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8966 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8967 redefined the Notify Payload into protocol specs.
8969 * Added silc_id_payload_parse_id to get ID directly from raw
8972 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8974 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8975 accept searching by Client ID as well.
8977 * Added support for LEAVE and SIGNOFF notify types in client library.
8979 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8980 to parse ID Payload from raw data.
8982 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8984 * Added flags parameter into silc_ske_assemble_security_properties
8985 function in lib/silcske/silcske.[ch].
8987 * Changed notify client operation to fit better for notify messages
8988 sent by server. The notify payload received from server is now
8989 passed to the application (after parsing it to SilcNotifyPayload).
8990 It is application's responsibility to retrieve the arguments
8991 from the payload and show the message the way it wants. The message
8992 sent by server is implementation specific.
8994 * Changed public keys to comply with the protocol specification.
8995 Old public keys are not supported anymore and are not compatible.
8997 * Removed nickname from Channel Payload as the latest draft removed
8998 it. The client must resolve the nickname from the NAMES command
8999 reply received when it joined the channel.
9001 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
9003 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9005 * Fixed some errors in protocol specification drafts.
9007 * Created lib/silccore/silcnotify.c to implement Notify Payload
9008 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
9009 generic payloads described by protocol specifications. The file
9010 includes implementations for ID Payload and Argument Payload.
9012 * Changed Command Payload implementation to use the new Argument
9013 Payload. Changed command_xxxx_payload to command_payload_xxxx
9014 to comply with SILC coding conventions.
9016 * Added suppport for Argument Payload handling in Notify Payload
9017 implementation as protocol requires it. Added the new support
9018 into server and client lib as well.
9020 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9022 * Added support for multiple nicknames on same channel. [n] is
9023 added locally to the nickname if there are more than one same
9024 nicknames on the channel.
9026 * Server now sends all nicknames that matched WHOIS request.
9027 Client also shows the list received from server.
9029 * Added TOPIC command to client side. User can now set and show
9030 current topic on channel.
9032 * Added MOTD command to client and server. Also, server sends the
9033 motd when client connects to the server.
9035 * Changed version strings to comply ISO 8601.
9037 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9039 * Fixed protocol error handling in client library. It should now
9040 cope even if the SKE fails for some reason.
9042 * Made new protocol specification drafts for submitting to IETF.
9044 * Implemented TOPIC command to server in silcd/command.c.
9046 * Added two new notify types into lib/silccore/silcnotify.h:
9047 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
9048 notify nickname change and topic setting/change on a channel.
9050 * API change of command_reply operation in client library. The
9051 application gets now the status type received from server as well.
9053 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9055 * Removed the function just added to lib/silcutil/silcschedule.[ch].
9057 * Cras fixed and optimized the packet handling even further and
9058 it should work now. Minor change to the prototype of function
9059 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
9061 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9063 * Added new function into lib/silcutil/silcschedule.[ch]:
9064 silc_schedule_with_fd to select() a specified fd. The function
9065 returns after timeout expires or data arrives or goes. The
9066 function is used by packet routines to wait that all data is
9067 received from network.
9069 * Fixed data reading from network in lib/silccore/silcpacket.c.
9070 The code now assures that all data is read from the fd and then
9071 continues packet processing. This was a bug fix since the code
9072 used to drop some data in some circumstances.
9074 * Added new function into lib/silcclient/client.[ch]:
9075 silc_client_start_key_exchange to start key exchange after
9076 connection has been established to server. The code internally
9077 now uses this funtion but its main purpose was to provide it
9078 for applications that perform their own connecting. After
9079 application has created a connection it merely calls this
9080 function to start the key exchange between client and server.
9081 The library takes care of everything else after that.
9083 Updated also lib/silcclient/README to explain the usage of
9086 * Do not send to application information that connection has
9087 been established. Application gets notified it by connect
9090 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9092 * Applied cras's patch to add silc_schedule_one function. The
9093 function runs scheduler once and returns.
9095 * Fixed the scheduler after cras messed it up. The timeout
9096 handling works now as it's supposed to work.
9098 * Added into lib/silccore/ silcnotify.h to include notify
9099 message types support. Changed silc_server_send_notify*
9100 functions, in server.[ch], to support those new notify types.
9101 Added the support for the notify types into client library,
9102 as well. Added new notify client operation into ops.h in
9105 * Changed silc_server_packet_send_to_channel to send normal
9106 packets instead of just channel message packets. The function
9107 is now used to send the notify packets to channels. It is not
9108 used to send channel message packets anymore, as server never
9111 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
9112 va_arg()s as it seems to require it nowadays. I guess, if SILC
9113 is compiled with older va_arg() the new code should work anyway.
9115 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9117 * Splitted core library. Core library (lib/silccore) includes
9118 now only SILC protocol specific core (and common) components.
9119 Created new utility library (lib/silcutil) that includes more
9120 generic purpose stuff. The stuff for util library was taken
9121 from the old core library. This was minor and easy split.
9123 * Created SILC Client Library (lib/silcclient) that includes
9124 implementation of the SILC client without user interface. This
9125 was major move from silc/ directory. The code has been changed
9126 so that it is transparent towards the user interface. The
9127 silc/ directory includes now the same user interface as before
9128 and it uses the new client library. Read lib/silcclient/README.
9129 Basicly, the client library performs everything else related
9130 to SILC except user interface handling. Also, configuration
9131 files are considered to be part of user interface and library
9132 does not handle them.
9134 This change also changed a lot of structures, function naming etc.
9135 Most important change was that SilcClientWindow object was
9136 renamed to SilcClientConnection in the client library. Created
9137 also new file lib/silcclient/ops.h. Also added new files
9138 silc/local_command.[ch] and silc/client_ops.[ch].
9140 All these changes were made to make it easier for user interface
9141 designers to create what ever user interface for the SILC client
9144 It is also expected that the server will be moved to lib
9145 directory as well and SILC Server Library will be created;
9146 sometimes in the future.
9148 * Removed Local commands from lib/silccore/silccommand.h as
9149 they are application specific and new client library does not
9150 handle any of those anymore.
9152 * Several functions moved to lib/silcutil/silcutilc.[ch] from
9153 old client implementation in silc/.
9155 * Added support for callback functions in SILC_LOG_* macros.
9156 Application can now set its own callbacks that will be called
9157 instead of using the default functions that will always print
9158 the debug messages to stderr (or stdout). Also, debugging can
9159 now be disabled by setting silc_debug to FALSE and re-enabled by
9160 setting it to TRUE. Note, that logging will still work even
9161 if debugging is disabled.
9163 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
9164 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
9165 silc_log_reset_debug_callbacks.
9167 * To enable debugging in silc client one must give now -d
9168 option on command line.
9170 * Changed silc_schedule_init to automatically allocate task queues
9171 if they are not allocated before calling it.
9173 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9175 * Added GMP 3.1 into math library.
9177 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9179 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
9180 a channel in SILC network. The packet is used by servers and
9181 routers to notify other routers that user has left a channel.
9182 This little feature was missing until now. Added the feature
9183 to protocol specification as well.
9185 Added functions: silc_server_send_remove_channel_user and
9186 silc_server_remove_channel_user into server.[ch].
9188 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
9189 lib/silccore/silcpacket.h. However, they are not implemented
9192 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9194 * Fixed joining to a channel and sending channel messages
9195 between server and router. The channel message sending should
9196 now work inside a cell.
9198 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9200 * Fixed the private message sending between server and router.
9201 The private message sending should now work inside a cell.
9203 * Added silc_server_replace_id into server.[ch] to replace
9204 existing ID in the SILC network.
9206 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
9207 and silc_idlist_replace_server_id into idlist.[ch] in server.
9209 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9211 * Fixed the server to server connections. Server can again now
9212 connect to router. Router to router connections probably does
9215 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9217 * Added dynamic protocol registering support. Now protocols can
9218 registered and unregistered on the fly. Patch by cras.
9220 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9222 * Added lib/contrib directory to hold routines that some platforms
9223 don't have but are needed by SILC.
9225 * Added getopt.c, getopt1.c and getopt.h from GNU C library
9226 into lin/contrib to provide getopt() and getopt_long() for
9227 those who don't have it.
9229 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9231 * Added AWAY command to client. When away message is set and
9232 client receives a private message packet the client automatically
9233 replies to the sender with the away message.
9235 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
9236 bug seemed to be the cause of recent problems when compiling
9239 * Added version detection support to SKE protocol specification
9240 and added the new changes to the SKE implementation as well.
9241 There were other minor changes in the SKE protocol as well.
9243 Many changes in lib/silcske/silcske.[ch] and in
9244 lib/silcske/payload.[ch].
9246 * Added ^U functionality, clear input line. Patch from cras.
9248 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9250 * Mainly small bugfixes on core library. Fixed some debugging
9251 logging and buffer overflow in silclog.c.
9253 * Updated config.sub and config.guess on the distribution tree.
9255 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9257 * Added command lagging support in server. Client may execute
9258 commands now only once in two seconds.
9260 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9262 * Optimized packet reception. MAC computation and checking is now
9263 also more optimized. A lot previously duplicated code is now
9264 used as generic by both client and server.
9266 * Fixed key pair generation in clientutil.c
9268 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9270 * Added into lib/silccore/silcbufutil.[ch] new function;
9271 silc_buffer_realloc.
9273 * Moved generic packet sending/encryption functions to
9274 lib/silccore/silcpacket.[ch] from client and server. Some
9275 rewriting of the functions.
9277 * Moved all generic packet reception/decryption functions to
9278 lib/silccore/silcpacket.[ch] from client and server. The
9279 packet processing is now much cleaner in both client and server.
9280 These were major changes in both client and server.
9282 * Created many common functions in server to do packet sending.
9283 Previously code were duplicated a lot, this has been removed
9286 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9288 * Rewrote major parts of the ID cache system. Don't know
9289 whether it is better now or not but at least the API is more
9292 * Major rewrite on ID cache stuff on client because of the ID
9293 cache API changes. Added idlist.c to client.
9295 * Also major rewrite on ID cache stuff on server as well.
9296 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9297 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9298 in hand, instead they are all put into the ID cache system now.
9299 All server_idlist_* routines uses ID cache now instead of
9300 traversing its own lists (those lists does not exist anymore).
9301 SilcIDList though still exists. Also, SilcXXXEntry's are
9304 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9306 * Finally made the SKE implementation compliant to the protocol
9307 specification. All mp integers are now binary encoded as
9308 opposed being HEX encoded.
9310 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9313 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9314 functions: silc_[encode/decode]_pem. Also added function
9315 silc_encode_pem_file to PEM encode with newlines ('\n') for
9318 * SILC public keys are now encoded either PEM or binary. Same
9319 option is for private keys as well. By default private keys
9320 are binary encoded and public keys PEM encoded. Silly HEX
9321 encoding were removed.
9323 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9324 function to create fingerprints.
9326 * Fixed a bug in SHA1; does not change the original data anymore.
9328 * Partly implemented INFO command on client and server side.
9329 Fixed CLEAR command. Changes to SERVER command; show current
9330 server(s) when giving command without arguments. Added
9331 VERSION command to client.
9333 * Added check to server that unregistered connections cannot
9334 execute commands (unless it is specificly allowed).
9336 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9338 * Fixed screen refresh.
9340 * Fixed channel joining bug from client. On some circumstances
9341 client tried to join to a channel it had already joined.
9343 * Added public key verification process into client's protocol.c.
9344 The client now verifies the public key from user and saves
9345 it into ~./silc/serverkeys/ directory.
9347 Added into: clientutil.[ch]: silc_client_verify_server_key.
9349 * Changed SKE protocol's silc_ske_initiator_finish function
9350 to accept callback function that verifies the received public
9351 key. Removed old silc_ske_verify_public_key function.
9353 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9355 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9356 silc_pkcs_private_key[_data]_set.
9358 * Made the password and public authentication more cleaner in
9359 server's protocol.c.
9361 * Removed historic and obsolete protocol `channel_auth' from
9362 both client and server.
9364 * Removed wrong way of sending command status messages from
9365 server to client in server's command.c. The old way violated
9366 protocol specification.
9368 Changes to silccore/silccommand.[ch]: removed
9369 silc_command_encode_status_payload -> not needed anymore,
9370 changed silc_command_encode_payload_va to accept extra
9371 argument on variable argument list. The argument type must
9372 now be provided to the function. Also, added new function:
9373 silc_command_encode_reply_payload_va which is same as
9374 normal command_encode_payload_va except command status type
9375 is provided as extra argument.
9377 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9379 * Added ~./silc directory handling. The directory includes the
9380 public and private keys for the client.
9382 Added silc_client_check_silc_dir, silc_client_create_identifier
9383 and silc_client_load_keys.
9385 * Implemented SILC protocol compliant public key. Added public
9386 and private key saving to and loading from files.
9388 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9389 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9390 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9391 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9392 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9394 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9395 silc_pkcs_load_[public/private]_key.
9397 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9399 * Added silc_server_get_route (route.[ch]) to get connection
9400 data for the fastest route for given ID.
9402 * Implemented INVITE command on client and server. The command
9403 were re-defined in the SILC Protocol Specification and the
9404 implementation now complies with the specification.
9406 * Implemented PING command on client and server.
9408 * Implemented NAMES command on client and server. The server side
9409 supports currently only normal server not router server yet.
9410 Some changes to NAMES definition in SILC protocol specification.
9412 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9414 * Implemented LEAVE command on client and server.
9416 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9417 again. This change was made to the protocol as well. Server
9418 should not violate the protocol specification anymore.
9420 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9422 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9423 was tested. SOCKS4 was not but should work anyway.
