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

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

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

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

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

210 Mon Sep 16 12:02:54 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
212 * Added 'app_context' to silc_schedule_init. It is an
213 application specific context that is delivered to application
214 in task callback functions. Affected files are
215 lib/silcutil/silcutil.[ch].
217 * The hb_context in SilcSocketConnection is not freed
218 automatically anymore (application must free it). Freeing
219 it automatic is inconsistent. Affected files are
220 lib/silcutil/silcsockconn.[ch].
222 Sun Sep 15 22:16:19 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
224 * Added support for removing explicitly added client connections
225 in rehash and closing the client connections if they were
226 unconfigured in the rehash. Affected file silcd/server.c.
228 * Added support for aborting automatically pending commands
229 that never receives the reply (to avoid memory leaks).
230 Added also silc_server_command_pending_timed to set the
231 specific timeout for pending command. Affected files are
232 silcd/command[_reply].[ch].
234 * Added SILC_STATUS_ERR_TIMEDOUT status. Updated protocol
235 specs and lib/silccore/silcstatus.h.
237 Sun Sep 15 12:25:10 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
239 * Changed the silc_get_time to accept time value as argument
240 or if zero is sent return current local time. Affected
241 file lib/silcutil/silcutil.[ch].
243 * Added STATS command to client library and Irssi SILC client.
244 Patch provided by Ville Räsänen <ville.rasanen@iki.fi>.
246 Wed Sep 11 09:22:00 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
248 * Assure that channel key is set before sending it. May
249 crash server otherwise. Affected file silcd/packet_send.c.
251 Tue Sep 10 09:50:08 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
253 * Assure that endless loop cannot happen with detached client
254 resolving on normal server. Added idlist status
255 SILC_IDLIST_STATUS_RESUME_RES. Affected files are
256 silcd/idlist.h and silcd/packet_receive.c.
258 Mon Sep 9 12:18:18 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
260 * Incoming file transfer request cannot use same session as
261 the sending session. This can happen when sending file to
262 yourself. Crashed the client on quit. Affected file
263 lib/silcclient/client_ftp.c. Bug #24.
265 Sun Sep 8 18:39:25 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
267 * Implemented the draft-riikonen-precense-attrs draft and
268 the Attribute Payload into the lib/silccore/silcattrs.[ch].
270 Sun Sep 8 13:13:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
272 * Distribute the SERVER_SIGNOFF notify also to local backup
273 routers from the primary router. The backup router may not
274 have the signing of local server directly connected and need
275 to know about the signoff. Affected file silcd/server_util.c.
277 * Use the primary router as the origin of the locally connected
278 server when it is disconnecting from the backup router since
279 that's where it really is coming from. Now the clients from
280 the disconnecting server are removed correctly and "shadow"
281 clients are not left to the backup router. Affected file
284 Sat Sep 7 22:26:50 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
286 * If normal server is standalone and found existing but disabled
287 channel, do not re-create the channel since it creates
288 duplicate same channels. Affected file silcd/server.c.
290 * Added anonymous client connections support to server. New
291 "anonymous" configuration option to ConnectionParams section
292 added. If set to true, the username and hostname information
293 of the client will be scrambled and anonymous user mode is
294 set automatically to the user. Affected files are
295 silcd/serverconfig.[ch], silcd/packet_receive.c and server.c.
297 Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
299 * In JOIN notify handling, mark that the cache entry of the
300 client cannot be expired. Can cause crashes on normal
301 server (asserts client->channels). Affected file is
302 silcd/packet_receive.c.
304 * From now on distribution versions are used as protocol versions
305 instead of by default using the Toolkit base version as protocol
306 version. Affected file prepare.
308 * Do not set the locally resolved hostname for local client
309 entry but take what server sends. This way the real hostname
310 is showed in WHOIS for yourself. Affected file is
311 lib/silcclient/idlist.c and lib/silcclient/client.c.
313 * Resolve local info with IDENTIFY when connecting to server.y
315 Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
317 * Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
318 for implied search (not needed on platforms which has native
319 pthreads library). Use --without-pthreads to disable threads.
320 Affected file is configure.in.pre
322 * Fixed --with-iconv on platforms which need to bypass (broken)
323 native iconv(). Affected file is configure.in.pre
325 Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
327 * Moved -C option parsing in Irssi SILC client at same time
328 as other options. The UI was initialized earlier and caused
329 problems on command line. Bug #16. Affected file is
330 irssi/src/silc/core/silc-core.c.
332 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
334 * Added global variable silc_log_timestamp that tells silclog
335 wether to print or not the timestamp in the logging files.
336 Affected file lib/silcutil/silclog.[ch].
338 * Added silcd configuration option Timestamp in the Logging
339 section. Affected file silcd/serverconfig.[ch],
340 doc/example_silcd.conf.in.
342 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
344 * Fixed fingerprint checking to check for entirely empty
345 fingerprint instead of two first bytes when determining
346 if it is set. Bug #18. Affected file silcd/command.c.
348 * Fixed duplicate PKCS name registering to not allow it.
349 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
351 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
353 * Conditionalize non-gcc compiler optimizations for various
354 platforms, enable those commented out. Cleanups.
355 Affected file lib/silcmath/mpi/configure.in
357 Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>
359 * silc_rng_exec_command() left zombie processes if command
360 didn't generate any output. Affected file
361 lib/silccrypt/silcrng.c
363 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
365 * Rewrote iconv checking, introduce --with-iconv for systems
366 which rely on libiconv. Check if iconv() provided by libc
367 is good enough, otherwise demand libiconv. Affected file
370 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
372 * Search for ldopen() also in libc. This enables SIM support
373 on *BSD systems. Based on patch from Alex Zepeda. Affected
374 file configure.in.pre
376 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
378 * Don't call AM_CONDITIONAL conditonally for SILC_THREADS.
379 This fixes prepare on *BSD systems. Affected file
382 Sun Aug 4 15:55:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
384 * More fixed for not having purge timeout for global clients
385 that are on channel. Affected files silcd/command_reply.c
388 * Fixed the rekey protocol to work with backup router connections.
389 Rekey packets are now allowed on disabled connections as
390 well. Affected files silcd/packet_send.c and server.c.
392 * Do not switch to be as backup router when shutting down and
393 closing the primary connection. Affected file silcd/server.c.
395 * Fixed memory leaks in backup router deleting. Added
396 silc_server_backup_free to free all data during shutdown of
397 server. Affected files silcd/server_backup.[ch].
399 Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
401 * Do not process commands if the sock->user_data is NULL.
402 Affected file silcd/command.c.
404 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
406 * Fixed buffer overflow and security problems (loosing bits
407 in CFB encryption) in SILC RNG. Problems reported by
408 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
410 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
412 * Added yet more checks that client is not expired on global
413 list if it is on channels. Affected file is
414 silcd/command_reply.c.
416 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
418 * Merged c0ffee's MIME signal patch which adds support for
419 sending also MIME messages in Irssi SILC Client, and handling
420 received MIME messages in a signal (and perhaps doing something
421 to non-textual MIME messages).
423 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
425 * Fixed pending command deletion in server and client library
426 to check the whole list instead of breaking after first found.
427 The affected files are silcd/command.[ch] and
428 lib/silcclient/command.[ch].
430 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
432 * Return NO_SUCH_CHANNEL error in USERS for channel that is
433 secret or private, otherwise it's possible to find out
434 whether a secret channel exists or not. Affected file
437 * If CMODE change fails during the mode setting, assure that
438 the old mode mask is set for the channel back. Affected
439 file silcd/command.c.
441 * Fixed passphrase saving on +a channel on normal server
442 after successful JOIN command. Affected file silcd/command.c.
444 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
446 * Remove server/router operator privileges in DETACH command,
447 since it's possible to resume to server where these
448 privileges would not be allowed for the client. Affected
449 file silcd/command.c.
451 * Do not set to wait for backup in rehash of the server.
452 Affected file silcd/server.c.
454 * Do not check listener sockets when counting how many
455 socket connections we have. Affected file is
458 * Do not announce disconnected clients that are remaining
459 in history (for WHOWAS). This is because SIGNOFF notify
460 for these has been sent earlier already. Affected file
463 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
465 * Buffer overflow with CUMODE command's mode->mode character
466 conversion. Reported by Ville Räsänen. Affected file
467 lib/silcutil/silcutil.c.
469 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
471 * Allow heartbeat packets to go disabled connections anyway.
472 Affected files silcd/server.c and silcd/packet_send.c.
474 * Do not broadcast New Channel packets with List flag set
475 in the packet to backup routers. The router must check
476 for the correctness of the packets before sending them.
477 It is possible that router will have enforce Channel ID
478 change and this would cause desync in the backup router.
479 Affected file silcd/packet_receive.c.
481 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
482 are handled in list parsing. They are not list packets
483 anymore. Affected file silcd/packet_receive.c.
485 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
487 * Stop waiting for backup router through the timeout, not
488 directly after backup router has arrived. Affected file
491 * Do not re-create channel keys and send them when removing
492 clients in server shutdown. Affected files are
493 silcd/server_internal.h and silcd/server_util.c.
495 * Notify distribution to backup routers was missing from
496 the silc_server_send_notify_dest function which caused
497 desyncing problems with backup router. Affected file is
500 * The client's channel removing was working wrong on
501 backup router. It assumed that it doesn't know global
502 information but backup router does know. For this reason
503 it could remove channel when it wasn't supposed to do that.
504 Affected file silcd/server.c and silcd/server_util.c.
506 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
508 * Stop for a couple seconds after badkup router has become
509 primary router. Affected file silcd/server.c.
511 * Added silc_server_remove_servers_by_server, which is used
512 to remove servers originated from some other server. Also
513 clients of those servers can be removed too. Affected file
514 silcd/server_util.[ch].
516 * When removing clients after a server has signed of remove
517 also all servers behind that server (unless they are known
518 to be available locally), and send SERVER_SIGNOFF for each
519 of the server separately. Also the signed off clients are
520 sent now separately per signed off server. The affected files
521 are silcd/server.c and silcd/server_util.[ch].
523 * All servers added with silc_idlist_add_server must always
524 have both "router" and "connection" pointers set. Otherwise,
525 bad server entries may be left around in the cache.
526 Affected file silcd/command_reply.c.
528 * Do not create the channel key in NEW_CHANNEL packet
529 processing if the channel is empty. Affected file
530 silcd/packet_receive.c.
532 * Completed backup router support for standalone routers.
533 Supports also servers in the cell that do not use the backup
536 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
538 * Fixed a bug in silc_string_regexify which did not add '^'
539 at the start of each string, and thus the matching was
540 not explicit. For example ban list iikone@*!*@* would
541 match also "priikone", which is wrong, it would have to be
542 *iikone@*!*@* to match also "priikone". Affected
543 file lib/silcutil/unix/silcunixutil.c.

547 * Enable all local server connections before updating client
548 caches when we've become backup router. Otherwise, signoff
549 packets may not reach the clients. Affected files are
550 silcd/server.c and silcd/server_util.[ch].
552 * Fixed a bug in version string parsing which could crash
553 the program with specially formatted version string.
554 Bug reported and patch provided by Ville Räsänen. Affected
555 file lib/silcutil/silcutil.c.
557 * Handle the disconnection immediately when DISCONNECT
558 packet is received in server. Affected file silcd/server.c.
560 * Primary router now waits a short time (10 seconds) for
561 backup router connection before accepting any other
562 connection (except local). Affected file silcd/server.c,
565 * Fixed a crash in client libary in NICK_CHANGE notify when
566 NICK_CHANGE arrived for client entry we are resolving
567 currently. Affected file lib/silcclient/client_notify.c.
569 * Call the sconn->callback completion even if error had
570 occurred. Start reconnecting always if connection to
571 primary router fails during backup router protocol.
572 Affected files silcd/server.c and server_backup.c.
574 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
576 * Added functions silc_server_send_opers and
577 silc_server_send_opers_notify to send packets stricly
578 to operators. Added macro SILC_SERVER_SEND_OPERS macro
579 to send variable argument notify to operators.
580 Affected files silcd/packet_send.[ch] and silcd/server.h.
582 * Removed UMODE rights checking with UMODE_CHANGE notify.
583 Affected file silcd/packet_receive.c.
585 * Server/router operator now receives notify when network
586 switches to backup router and when it resumes the use of
587 primary router. Affected file silcd/server.c and
588 silcd/server_backup.c.
590 * Fixed the updating of client information after backup
591 resuming protocol is over; update all except local clients
592 to the new primary router. The affected file is
595 * Added support for closing active connections in rehash
596 that were unconfigured by the user. Supports currently
597 closing server and router connections. Affected file
600 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
602 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
604 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
605 is NULL since seems that on some platforms NULL is allowed
606 and on some it's not. Fallback encoding is used instead.
607 Affected file lib/silcutil/silcstrutil.c.
609 * Fixed statistics updating for incoming server connection
610 which could cause problems when re-connecting. Affected
613 * Preliminary backup router support for standalone router
614 added. Affected files in silcd/.
616 * Mark server connections in backup router disabled before
617 and after backup protocol. Affected file is
618 silcd/server_backup.c.
620 * Added support for reconnecting to remote server connection
621 even if the protocol fails, and if the configuration wants
622 us to keep trying to connect anyway.
624 Server connection is not allowed to backup router if
625 backup router does not have connection to primary router yet.
627 Affected file is silcd/server.c.

631 * Added silc_client_udpate_server function to update changed
632 server info. Affected file lib/silcclient/idlist.[ch].
634 * Added check for server entries that are being resolved when
635 notify is received. If being resolved, handle the received
636 notify only after it's resolved so that all notifys are
637 handled in same order as received from the server.
639 Added similar resolver check to channel entries. Every
640 notify that cause resolving of any information that affects
641 channel entry marks the channel entry in waiting state.
642 After whatever resolving is over the waiters are signalled
643 and only then the notifys are handled in the same order
644 as delivered from the server.
646 Affected files are lib/silcclient/idlist.[ch], and
649 * Fixed KILLED notify handling in normal server. Affected
650 file silcd/packet_receive.c.
652 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
653 is locally connected, or was locally connected (but may
654 be detached and connection is not active). Added also
655 SILC_IS_LOCAL for checking this status. Affected files
656 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,

661 * Don't send or handle TOPIC_SET if topic is already set and
662 is same as being set. Affected files silcd/command.c and
663 silcd/packet_receive.c.
665 * Fixed CMODE change rights checking to work correctly when
666 removing modes by operator. Affected file is
669 * Fixed some handling with New Channel packet in router and
670 fixed some CMODE_CHANGE notify handling in server and router.
671 Affected file is silcd/packet_receive.c.

683 to the sender of the notify too, to avoid situation where two
684 notifys are in the network at the same time going to oppsite
685 directions. Affected file silcd/packet_receice.c.
687 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
689 * Delete the client from channel even if the cilent->id is
690 NULL. It was possible that client was deleted without
691 removing from channels (theoretically at least). Affected
692 file silcd/server.c and silcd/server_util.c.
694 * Free the client data too when resuming is not successful.
695 Affected file silcd/packet_receive.c.
697 * Merged some code from c0ffee's silc-plugin. Affected files
698 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
700 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
701 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
702 to the primary router connection, the other one returns
703 TRUE if packet must be broadcasted to network.
705 * All notifys that are destined to primary router (to network)
706 are now automatically sent to backup routers even if the
707 router is standalone (and has backup router). Affected files
710 * Added --without-irssi and --without-silcd configuration
711 options for disabling the compilation of these applications.
712 Affected file configure.in.pre and prepare.

718 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
720 Added also SILC_STRING_LANGUAGE which is language and charset
721 specific encoder and decoer for those platforms that support
722 iconv(). It can convert the UTF-8 to and from the locale
723 specific character set.
725 Affected file lib/silcutil/silcstrutil.[ch].
727 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.

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

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

1373 * Redefined the Status Payload to include now two 8 bit fields,
1374 instead of one 16 bit field. This now makes it possible to
1375 send list of errors. Updated the protocol specs and the code
1376 in core library, client library and server. Protocol TODO #1.
1377 Affected files are lib/silccore/silccommand.[ch],
1378 lib/silcclient/command_reply.[ch], silcd/command.c,

1408 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1410 * Added STATS command to the protocol after all, to return
1411 various statistical information about the network. It can
1412 be used by clients to retrieve statistical information, and
1413 servers may use it to to fetch cell and network wide
1414 statistics from router. Updated the protocol specs and
1415 implemented it to the server. Protocol TODO #16.
1416 Affected files are lib/silccore/silccommand, silcd/command.[ch],

1421 * The LIST command reply in client libary now adds new channel
1422 entry if the returned channel doesn't exist yet in cache,
1423 and returns the channel entry to the application in the
1424 command_reply client operation. Affected file is
1425 lib/silcclient/command_reply.c.
1427 * Changed the channel message payload's MAC generation to
1428 include the IV in the MAC as well. This way all relevant
1429 parts of the channel message payload are authenticated also
1430 with the channel message MAC (and not only by packet MAC).
1431 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1432 Affected file is lib/silccore/silcchannel.c.
1434 * Fixed the SKE to save the remote version, since the

1509 to define the payload for DATA flag. Added the flags to
1510 the implementation. Protocol TODO #9. Affected file is
1511 lib/silccore/silcchannel.h.
1513 Changed the client library to return the message length

1557 * Some client implementations quit network by doing first LEAVE
1558 and then immediately SIGNOFF (like Bombyx). We now do check
1559 after a short time after LEAVE notify and check whether the
1560 client is still valid after LEAVE, and if not we remove it from
1561 cache. Affected file is lib/silcclient/client_notify.c.
1563 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>

1582 lib/silccore/silcid.c.
1584 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1586 * Changed the object argument for silc_cipher_register,
1587 silc_hash_register, silc_hmac_register and silc_pkcs_register
1588 to const. Affected files are lib/silccrypt/silccipher.[ch],
1589 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1591 * Changed the silc_get_username and silc_get_real_name to
1592 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1594 * Fixed the Irssi SILC Client to use the silc_get_username and
1595 silc_get_real_name insted of glib routines since the glib
1596 routines only corrupt stack. Fixes the Irssi SILC to work in
1597 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1599 * Fixed the Irssi to not use g_get_home_dir since it crashes
1600 or returns garbage on cygwin and corrupts stack. Added function
1601 get_home_dir to Irssi routines. Affected files are
1602 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1604 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1606 * Made some structure optimizations. SFTP memory FS MemFSEntry
1607 entry structure. Optimized SilcTask structure. Optimized
1608 SilcPacketContext structure.
1610 Affected files lib/silcsftp/sftp_fs_memory.c,
1611 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1613 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1615 * And yet again reverted back the config thing since Johnny
1616 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1619 * Fixed memory leaks from config object. Affected files are
1620 silcd/serverconfig.[ch].
1622 * Added support for adding new connections to the server in rehash.
1623 After rehash they take effect.
1625 Added support for changing the maximum allowed connections in
1626 rehash. The number can grow but going smaller is not supported.
1628 Added function silc_server_num_sockets_by_remote to the
1629 silcd/server_util.[ch].
1631 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1633 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1635 * Added preliminary checking during config parsing for a valid
1636 public/private key and removed further checks in the code.
1637 Affected files are silcd/serverconfig.[ch], server.c.
1639 * Moved functions silc_server_drop() and silc_server_daemonise()
1640 from server.c to silcd.c since they are stricly related to
1641 the application activity.
1643 * Reverted a small part of the automatic ref/unref since
1644 it caused a double unref in some situations. Affected
1645 files are silcd/silcd.[ch], server.c, serverconfig.c.
1647 * Added some .cvsignore files in the lib directory.
1649 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1651 * Fixed silc_net_gethostbyaddr to correctly resolve by
1652 address. Affected file lib/silcutil/silcnet.c.
1654 * Fixed the notify relaying to client. The HMAC to be used
1655 with relayed packets ws wrong and caused decryption failure
1656 at the client end. Affected file is silcd/packet_receive.c.
1658 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1660 * Created new branch silc_protocol_1_0_branch.
1662 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1664 * Changed the silc_server_config_* routines to be SilcServer
1665 independent. They are now officially application specific code
1666 and not part of generic server implementation. Affected files
1667 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1669 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1671 * Added automatic referencing of config context in the
1672 silc_server_config_alloc, and automatic unreferencing in the
1673 silc_server_config_destroy. Affected files are
1674 silcd/serverconfig.[ch], silcd/silcd.c.
1676 * Fixed the silc_log_quick handling in the logging routines.
1677 It didn't log quickly when it was TRUE. Affected file is
1678 lib/silcutil/silclog.c. Also the flush delay was set even
1679 if it was 0 in config file. Affected file is
1680 silcd/serverconfig.c.
1682 * Added support for changing key pair of the server in rehash.
1683 Affected file silcd/server.c.
1685 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1687 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1688 too early, before getting the channel entry. Affected file
1689 is silcd/packet_receive.c.
1691 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1693 * Added functions silc_server_config_[ref/unref], these are used
1694 to prevent that the config object is destroyed.
1696 No longer directly affect global variables silc_log_quick and
1697 silc_log_delay, they are first cached inside the config object
1698 and then applied with silc_server_config_setlogfiles().
1700 silc_server_config_set_defaults() is now internal to
1701 serverconfig.c, there are no reasons to show this internal stuff
1704 Affected files are silcd/serverconfig.[ch].
1706 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1707 fprintf's to stderr, since some code may be executed again after
1708 the server went into the background. Affected files are
1711 * Added rehash support. Added function silc_server_rehash() that
1712 will perform all the basic tasks of the rehashing procedure.
1714 * Added command line option `-x, --hexdump'. This will enable the
1715 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1716 The option `--hexdump' implies `--debug'.
1718 * Fixed a bad bug in the logging APIs (silcutil library) where
1719 the application would crash after calling silc_log_reset_all().
1721 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1723 * Fixed the KICKED notify handling in client library to
1724 correctly remove the channel and all entries from the
1725 channel when I was kicked. This bug crashed the client.
1727 Fixed yet another but in KICKED notify handling to remove
1728 the kicked client correctly from the channel.
1730 Affected file is lib/silcclient/client_notify.c.
1732 * Fixed a minor bug in looking up correct client entry
1733 in KICKED notify in server. Affected file is
1734 silcd/packet_receive.c.
1736 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1737 sources correctly to distribution. Fixes --with-gmp option.
1739 * Removed the manual rehashing from ID Cache, and changed it
1740 to use the SILC Hash Table's auto rehash feature. Affected
1741 file is lib/silccore/silcidcache.c.
1743 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1745 * Fixed a bug in the silc_client_nickname_format function that
1746 handles the multiple same nickname formatting. Two clients
1747 with same nickname caused problems after the first one left
1748 and rejoined. It didn't format the nickname correctly.
1749 Affected file is lib/silcclient/idlist.c.
1751 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1753 * Don't change the topic if olod topic is same as new one.
1754 Affected file is silcd/packet_receive.c.
1756 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1758 * Added cross-reference support to the SILC Documentation
1759 generator. All types across all HTML files are now cross-
1760 referenced. Affected files util/robodoc/generator.c and
1761 scripts/silcdoc/silcdoc.
1763 * Added file lib/silcutil/silctypes.h to include all the
1764 arithmetic type definitions and some macros. Removed
1765 includes/bitmove.h and moved macros to silctypes.h.
1767 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1769 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1771 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1773 * Added `type' argument to silc_id_payload_parse_id function which
1774 now returns the type of the ID to the sent pointer. Affected
1775 file is lib/silccore/silcid.[ch].
1777 * Added check for CMODE_CHANGE notify type that mode change is
1778 allowed by the sender. Affected file silcd/packet_receive.c.
1780 * Added check for CUMODE_CHANGE notify type that mode change is
1781 allowed by the sender. Affected file silcd/packet_receive.c.
1782 Added the ID type as CUMODE_CHANGE notify type as argument
1783 to the `notify' client operation. Affected files are
1784 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1786 * Added function silc_client_add_server to the client library.
1787 Added support for resolving also channel and server info when
1788 received unknown entity in notify packet. Affected files are
1789 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1791 * Added function silc_command_get_status to return the command
1792 status from the command reply's argument payload. Affected files
1793 are lib/silccore/silccommand.[ch].
1795 * Added check for KICKED notify type that the kicking is
1796 allowed by the client. Affected file silcd/packet_receive.c.
1798 * Created function silc_get_input which can be used to get input
1799 (echo on or off) from user on command line. Affected files are
1800 lib/silcutil/silcutil.[ch].
1802 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1804 * Optimized silc_server_packet_relay_to_channel function.
1805 Added new function silc_channel_message_payload_encrypt which
1806 can be called directly if channel message payload needs to
1807 be encrypted and is already encoded (no need to call _encode
1808 function). Packet relaying is now done by router without any
1809 extra memory allocations. Affected files are
1810 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1811 silcd/packet_send.c.
1813 * Fixed the INVITE notify handling. It took wrong arguments
1814 as invite list and invite delete. Affected file is
1815 silcd/packet_receive.c.
1817 * Added check for TOPIC_SET notify type that the topic change is
1818 allowed by the client. Affected file silcd/packet_receive.c.
1820 * Added check for INVITE notify type that inviting is allowed by
1821 the client. Affected file silcd/packet_receive.c.
1823 * Changed the silc_server_client_on_channel to return the
1824 SilcChannelClientEntry as well. Moved the function
1825 silc_server_check_cmode_rights to server_util.[ch].
1826 Affected files are silcd/server_util.[ch], silcd/command.c.
1828 * Added function silc_server_check_umode_rights to check whether
1829 changing client's user mode is allowed. Added check for
1830 UMODE_CHANGE notify type that the umode change is allowed
1831 by the client. Affected files are silcd/server_util.[ch],
1832 silcd/packet_receive.c and silcd/command.c.
1834 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1836 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1837 ID length. It ignored that ID can be IPv6 based as well.
1838 Affected file lib/silccore/silcpacket.h.
1840 * Fixed the silc_id_id2str and silc_id_str2id to take the
1841 IPv6 address offset's into consideration. Affecte file is
1842 lib/silccore/silcid.c.
1844 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1846 * Fixed the internal Unix scheduler functions to check for
1847 NULL context they may receive. The affected file is
1848 lib/silcutil/unix/silcunixschedule.c.
1850 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1852 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1853 can specify different directory with --home command line
1854 parameter. Affected files irssi/src/silc/core/client_ops.c,
1857 * SILC-specific commands aren't now executed if the active server
1858 isn't of SILC-type, so there won't be problems with having
1859 IRC and SILC protocol support in same client. Affected files
1860 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1863 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1865 * Improved the signal support in SILC Schedule. Added new
1866 function silc_schedule_signal_call which is used by application
1867 to mark a signal to be called. It is now safe to perform
1868 any kind of tasks in signal callbacks since it is guaranteed
1869 that the application specified signal callback is called
1870 after the signal is over. Affected files are
1871 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1873 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1875 * Added `name' field to SilcChannelPrivateKey to represent
1876 application given name for the key. Moved also the context from
1877 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1878 Added the `name' argument also to the function
1879 silc_client_add_channel_private_key.
1881 Added function silc_client_current_channel_private_key to set the
1882 current channel private key in use.
1884 Added "change" command to KEY command which can be used to change
1885 the current channel private key. Bound the command also to
1886 alt+K (Alt+Shift+k).
1888 Also affected files lib/silcclient/client_channel.c,
1889 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1891 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1893 * Added silc_rng_get_byte_fast function in to the
1894 lib/silccrypt/silcrng.[ch].
1896 * Changed the interface of silc_packet_assemble and the
1897 silc_packet_send_prepare. If silc_packet_assmble is now
1898 called the application does not call silc_packet_send_prepare
1899 because the library will call it automatically. These
1900 interfaces now also return a reference to the outgoing buffer
1901 which includes the assembled packet, which the application can
1902 use to encrypt the packet.
1904 Affected files are lib/silccore/silcpacket.[ch],
1905 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1906 silcd/packet_send.c, server_backup.c and packet_receive.c.
1908 * Fixed a packet sending bug on very high load, where outgoing
1909 packet queue wasn't handled correctly and packets got corrupted.
1910 Affected files are lib/silcutil/*/silc*sockconn.c,
1911 lib/silcclient/client.c and silcd/server.c.
1913 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1915 * Added macro SILC_PACKET_DATALEN which can be used during
1916 packet assembling to check whether the data to be added to
1917 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1918 len is truncated until it fits it.
1920 Added checks for maximum length of channel message payload and
1921 private message payload also.
1923 Added checks for maximum packet length in server and in
1926 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1927 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1928 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1929 lib/silcclient/client_prvmsg.c.
1931 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1933 * Added silc_server_packet_queue_purge call to the
1934 silc_server_disconnect_remote to assure that all data in the
1935 queue before disconnecting is sent to the network. Affected
1936 file silcd/server.c.
1938 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1940 * Added the deleting of server's own ID cache entry to the
1941 silc_server_free function. Free also everything else that
1942 has been allocated in silc_server_init. The affected file
1945 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1947 * Added functions silc_parse_version_string, silc_version_to_num,
1948 and silc_ske_parse_version to parse SILC protocol style version
1949 strings. Affected files lib/silcutil/silcutil.[ch] and
1950 lib/silcske/silcske.[ch].
1952 * Added new configuration params: version_protocol, version_software
1953 and version_software_vendor to specify what version the remote
1954 host must at least be to be able to connect to server. The vendor
1955 string can be regex matched too. Added new function
1956 silc_server_connection_allowed to check maximum number of allowed
1957 connections, and allowed versions for incoming connections.
1958 Affected files are silcd/server.c, server_util.[ch] and
1961 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1963 * Added preliminary support for signals in scheduler. The
1964 signals we care about are now blocked always when the scheduler
1965 is locked. This way we can synchronise the use of signal with
1966 scheduler. It is guaranteed that when signal occurs the scheduler
1967 is not locked, and thus new tasks can be safely added to the
1970 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1971 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1972 Added new platform specific routines
1973 silc_schedule_internal_signals_[un]block and
1974 silc_schedule_internal_signal_[un]register.
1976 Added new functions to SILC Schedule API:
1977 silc_schedule_signal_[un]register. Each signal that application
1978 is going to use should be registered to the scheduler.
1980 Affected files are lib/silcutil/silcschedule.[ch],
1981 lib/silcutil/*/silc*schedule.c.
1983 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1985 * Check for unauthenticated client and server in the
1986 silc_server_new_client and silc_server_new_server functions.
1987 Affected file silcd/packet_receive.c.
1989 * Added function silc_string_is_ascii to check whether given
1990 string is 7-bit ASCII string. Affected files are
1991 lib/silcutil/silcutil.[ch].
1993 * Added function silc_id_is_valid_server_id into the
1994 silcd/serverid.c and added checking for valid Server ID's in
1995 silc_server_new_server. The Server ID must always be based
1996 on the server's public IP address.
1998 * Added logging of DISCONNECT packet message in the server.
1999 Affected file silcd/server.c.
2001 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2003 * Changed all library interfaces that use Global RNG to also
2004 accept SilcRng as argument. Affected files are
2005 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
2006 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
2007 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
2008 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
2009 lib/silccrypt/rsa.c.
2011 * Added function silc_pkcs_generate_key to the
2012 lib/silccrypt/silcpkcs.[ch] for applications so that they
2013 don't need to do pkcs->pkcs->init calls anymore.
2015 * Remove SilcSocketConnection from the SFTP API since it really
2016 wasn't needed there. The application has the information
2017 saved in its contexts anyway and the SFTP layer doesn't need
2018 know about it. Affected files lib/silcsft/silcsftp.h and
2019 lib/silcsftp/sftp_[server/client].c.
2021 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
2022 The SilcSimContext is not SilcSim.
2024 * Fixed possible buffer overflows in silc_id_render in the
2025 lib/silcutil/silcutil.c.
2027 * On EPOC the global crypto module lists are not used at all
2028 in the crypto library. Added support for using the constant
2029 algorithm list on EPOC. Affected files are
2030 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
2033 * Fixed the handling of third parameter of KICKED notify, since
2034 it was mistakenly updated to SILC Protocol 1.0 even though it
2035 is to be included in 1.1. Since it is not in 1.0 it is not
2036 mandatory, and this fix now handles it only if it is provided,
2037 and it is not error if it is not provided. Affected file
2038 lib/silcclient/client_notify.c.
2040 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2042 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
2043 client. Affected file irssi/src/silc/core/client_ops.c.
2045 * Merged with Irssi 0.8.4 from irssi.org CVS.
2047 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2049 * Check for valid socket connection in client entries before
2050 sending any messages. Fixes a crash, but doesn't fix some
2051 other underlaying bug that is lurking there. Affected
2052 file silcd/packet_send.c.
2054 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
2056 * $usermode, $cumode and $cumode_space expandos shouldn't do
2057 anything with non-SILC server records. Affected file
2058 irssi/src/silc/core/silc-expandos.c
2060 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2062 * Fixed the silc_net_check_[host/local]_by_sock to support
2063 IPv6 bound sockets as well. Now they can return IPv6 addresses
2064 as well. Affected file lib/silcutil/silcnet.c.
2066 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
2067 Affected lib/silcutil/unix/silcunixnet.c.
2069 * Fixed ID rendering (at least on some platforms, not NetBSD)
2070 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
2072 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2074 * Added silc_hash_public_key and silc_hash_public_key_compare

2076 hash public keys and compare public keys in hash table. Affected
2077 file lib/silcutil/silcutil.[ch].
2079 * Added support for specifying multiple public keys for Client
2080 connection section in server configuration file. This makes it
2081 possible to accept multiple public keys from same host, or to
2082 make a section that accepts any incoming host, and have the
2083 accepted public keys listed in the section.
2085 Added functions silc_sever_[find/get]_public_key, added the
2086 support for this actually to all connection sections but only
2087 the Client section is currently allowed to specify multiple

2198 old name went against naming convention. Applications now
2199 include "silcclient.h" instead of "clientlibincludes.h".
2200 Removed includes/clientlibincludes.h, it is redundant now.
2202 * Renamed includes/version.h to silcversion.h.
2204 * Added really preliminary support for OS/2 into the util
2205 library. Only thread & mutex API is implemented, others
2206 are still to be implemented. Created the lib/silcutil/os2/

2240 * Added `user_count' to the SilcChannelEntry which now tells the
2241 number of users on the channel. The user count is now saved
2242 in normal server of global channels as well. Affected files
2243 silcd/server.c, idlist.h, packet_receive.c and command.c.
2245 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
2246 include file utility functions.

2262 the SKE interface a bit.
2264 * Fixed padding problem in PKCS#1. The padding was not actually
2265 random since the random number generator was used incorrectly.
2266 This security bug affects only when encrypting with PKCS#1, and
2267 it is not currently used at all in SILC. SILC only use signing
2268 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.

2331 Affected files irssi/src/silc/core/silc-core.c,
2332 irssi/src/fe-text/silc.c.
2334 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2336 * Added new configuration options and blocks:
2337 keepalive_secs, reconnect_count, reconnect_interval,
2338 reconnect_interval_max, reconnect_keep_trying and
2339 require_reverser_lookup. Added ConnectionParam block, and
2340 implemented the connection parameters when connecting as
2341 initiator and when accepting connections as responder.

2353 the connection configuration object from the SilcServerConnection
2354 object instead of finding it during the connecting phase.
2355 Added the configuration object to SilcServerConnection struct.
2356 Affected files silcd/server_internal.h, server.c.
2358 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2360 * Add the client on channel after it was resolved at the
2361 channel message receiving, and it was not already on the
2362 channel. Affected file lib/silcclient/client_channel.c.
2364 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2380 authentication to be set at the same time.
2382 Added `prefer_passphrase_auth' setting in config file which
2383 can be used to set to prefer passwd auth if both passwd and
2384 public key is set. If not set, public key is preferred.
2385 This has effect only when being initiator (responder will try
2388 Added support for authentication with passphrase and public key
2389 at the same time. The passphrase is tried first always since
2390 it is faster to check.
2392 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2394 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2440 * Fixed the file transfer's key agreement payload to include
2441 zero port also if the hostname is NULL because it could not
2444 Call file transfer monitor callback now also if error occurs
2445 during key agreement protocol.
2447 Changed the silc_client_file_send interface to return the
2448 SilcClientFileError instead of session id. The session ID
2449 is returned into pointer provided as argument.

2464 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2465 SILC_LOG_WARNING to give out Warning and not Error. Affected
2466 file lib/silcutil/silclog.c.
2468 * Fixed the channel message payload decryption in the function
2469 silc_channel_message_payload_decrypt to not modify the original
2470 buffer before it is verified that the message decrypted
2471 correctly. Otherwise, next time it is called with correct
2472 channel key it won't encrypt since the payload is corrupted.
2473 Affected file lib/silccore/silcchannel.c.
2475 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2488 the table with foreach callback. The current entry may
2489 become invalid in the callback but it was referenced after
2490 the callback returned.
2492 Do not allow auto rehashing of hash table during the
2493 silc_hash_table_foreach operation, for same reasons as it is
2494 not allowed for SilcHashTableList. Affected files are
2495 lib/silcutil/silchashtable.[ch].
2497 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

2521 * Fixed a bug in hash table tarversing. While the hash table
2522 is traversed with SilcHashTableList the table must not be
2523 rehashed. It is now guaranteed that auto rehashable tables
2524 are not rehashed while tarversing the list. Also defined that
2525 silc_hash_table_rehash must not be called while tarversing
2526 the table. Added function silc_hash_table_list_reset that must
2527 be called after the tarversing is over. The affected files are
2528 lib/silcutil/silchashtable.[ch].
2530 * Changed all hash table traversing to call the new
2531 silc_hash_table_list_reset in server and in client library.
2533 * Added function silc_client_on_channel to return the
2534 SilcChannelUser entry if the specified client entry is joined
2535 on the specified channel. This is exported to application as
2536 well. Affected files lib/silcclient/client_channel.c, silcapi.h.

2544 * Fixed the WHOWAS command's reply sending to support the
2545 lists correctly. Affected file silcd/command.c.
2547 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2549 * When sending JOIN command to router for processing the
2550 sender's old command identifier was not saved back to the
2551 sender's command context, fixed now. The affected file is
2554 * Create the key in JOIN command of the router did not return
2555 the channel key, added check for this. Affected file is
2558 * Fixed a channel ID update bug in JOIN command reply. Do
2559 not directly upgrade the ID but call the function
2560 silc_idlist_replace_channel_id if the ID was changed.
2561 Affected file silcd/command_reply.c.
2563 * Fixed memory leaks from command calling if it would fail.
2564 Affected file silcd/command.c.

2591 functions. Affected file silcd/server.c.
2593 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2594 which ID was changed. This way the router will send the
2595 user list for the channel again, and server won't be in
2596 desync in some rare circumstances. Affected file is
2597 silcd/packet_receive.c.
2599 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2605 * Fixed the BAN notify handling to correctly remove ban
2606 list. Affected file silcd/packet_receive.c.
2608 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2610 * Fixed some header addition to Toolkit distribution in
2611 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2613 * Added lib/silcclient/client_ops_example.h as an template
2614 file for application programmers to quickly start using
2615 the SilcClientOperation functions in their application.
2616 Updated the lib/silcclient/README as well to tell about this
2617 nice file made available.
2619 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2621 * Call silc_server_remove_from_channels when removing client
2622 entry when NO_SUCH_CLIENT_ID was received. Affected file
2623 is silcd/command_reply.c.
2625 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2627 * Added server & router operator statistics updating. Affected
2628 file silcd/packet_receive.c and silcd/command.c.
2630 * Fixed the SERVER_SIGNOFF notify handling on normal server
2631 not to save the history information for clients. Same was
2632 fixed earlier in remove_clients_by_server function, but not
2633 here. Affected file silcd/packet_receive.c.
2635 * Raised the default connection-retry count from 4 to 7 in
2636 server. Affected file silcd/server.h.
2638 * Cancel any possible reconnect timeouts when we start the
2639 key exchange. Affected file silcd/server.c.
2641 * Do not reconnect on connection failure when SCONNECT was
2642 given. Affected files silcd/server.[ch].
2644 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2646 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2648 * Fixed the NICK command to always give the unformatted
2649 nickname to the one giving the NICK command. If unformatted
2650 nickname is cached already it will be formatted and the
2651 local entry will always get the unformatted nickname.
2652 Affected file lib/silcclient/idlist.c.
2654 * Fixed some double frees from client library commands.
2655 Affected file is lib/silcclient/command.c.
2657 * Fixed CUMODE command in server to assure that no one can
2658 change founder's mode than the founder itself, there was a
2659 little bug. Affected file silcd/command.c.
2661 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2663 * Removed the SilcClientCommandDestructor from the client
2664 libary, it is not needed anymore. Affected files are
2665 lib/silcclient/silcapi.h, command[_reply].[ch],
2666 client_notify, idlist.c.
2668 * Fixed GETKEY command to first resolve client, and then
2669 resolve the server only if the client was not found, instead
2670 of resolving both at the same time. Affected file is
2671 lib/silcclient/command.c.
2673 * Added silc_client_start_key_exchange_cb and lookup the
2674 remote hostname and IP address before starting the key
2675 exchange with server. The affected file is
2676 lib/silcclient/client.c.
2678 * The server's public key is now saved using the IP address
2679 of the server and not the servername for the filename.
2680 The hostname public key filename is checked as an fall back
2681 method if the IP address based filename is not found.
2683 Fixed the GETKEY command to save the fetched server key
2684 in correct filename.
2686 Print the remote server's hostname now when new key is
2687 received during connection process. Affected file is
2688 irssi/src/silc/core/client_ops.c.
2690 * Return always our own public key to the client if it asks
2691 for it with GETKEY command. Affected file silcd/command.c.
2693 * Removed the use_auto_addr variable from default config
2694 file since it was in wrong section. Affected file is
2697 * Fixed TOPIC_CHANGE notification to not route it when it
2698 was sent using silc_server_send_notify_to_channel function.
2699 Affected file silcd/command.c.
2701 * Fixed silc_server_send_notify_kicked to send the kicker's
2702 Client ID also, it was missing. Affected files are
2703 silcd/command.c, silcd/packet_send.[ch].
2705 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2707 * Do not save client history information in SERVER_SIGNOFF.
2708 Fixes the bug in normal server that it does not detect
2709 the client becoming valid after the server becomes back
2710 online. Affected file silcd/server_util.c.
2712 * Added `sock_error' field into the SilcSocketConnection
2713 context. When error occurs during socket operation (read
2714 or write) the error is saved. Added also new function
2715 silc_socket_get_error to return human readable socket error
2716 message. Affected files are lib/silcutil/silcsockconn.[ch],
2717 lib/silcutil/unix/silcunixsockconn.c, and
2718 lib/silcutil/win32/silcwin32sockconn.c.
2720 * The server now prints the socket error message in the
2721 signoff for client. Affected file silcd/server.c.
2723 * Fixed the `created' channel information sending from router
2724 to server in JOIN command. Checks now whether the channel
2725 really was created or not and set it according that.
2727 Fixed the JOIN command to use the client entry's current
2728 ID during the joining procedure instead of the one it sent
2729 in the command (it is checked though), since it can change
2730 between the packet processing and command processing, and
2731 would just case unnecessary pain in the client end. Affected
2732 file silcd/command.c.
2734 * Fixed a channel key payload sending to use correct channel
2735 ID when the server was forced to change the channel's ID by
2736 router. Router sent the key payload with the old Channel ID.
2737 Affected file silcd/packet_receive.c.
2739 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2741 * Call silc_server_save_channel_key only if the key payload
2742 was provided in the JOIN command's command reply. Affected
2743 file silcd/command_reply.c.
2745 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2747 * Fixed silc_mp_sizeinbase to return the value correctly with
2748 MPI. Affected file lib/silcmath/mp_mpi.c.
2750 * Fixed the stop_server signal to correctly stop the scheduler
2751 and gracefully stop the server when SIGTERM or SIGINT signals
2752 are received. Affected file silcd/silcd.c.
2754 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2756 * Simple handling of TERM and HUP signals. Also added some log
2757 flushing call around. Affected file is
2760 * Fixed small bugs in silclog.c. Now buffering output will take
2761 effect after 10 seconds since startup: This will ensure that
2762 no important startup messages are lost. Also output redirection
2763 will preserve original format ([Date] [Type] message).
2764 Affected file is lib/silcutil/silclog.c.
2766 * Added two options to the config file, in the logging section:
2767 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2768 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2770 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2772 * Do not print the warning about log files not being initialized
2773 more than once to avoid excess logging. Affected file is
2774 lib/silcutil/silclog.c.
2776 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2777 the SIM copying in make install in Makefile.am.pre.
2779 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2781 * Rewritten silclog APIs. Globally interesting changes follows:
2782 silc_log_set_files() changed to silc_log_set_file().
2783 silc_log_set_callbacks() changed to silc_log_set_callback().
2784 ROBOdoc documented silclog header file.
2785 SilcLogCb now returns bool to wether inihibit the default
2786 handler or not (to keep the old behaviour return always TRUE).
2787 The new APIs should also fix the problem of the
2788 silcd_error.log file that was written in the current directory.
2791 Log files streams will remain opened after silc_log_set_file()
2792 call, means less CPU usage notably on high traffic servers.
2793 File streams are now full buffered, and flushed to the disk
2794 every 5 minutes, lesses HD activity and CPU usage.
2795 Messages can be redirected, allowing admins to configure
2796 one single logfile for all server messages.
2797 the silc_log_quick global variable to activate fast-logging.
2798 Affected files lib/silcutil/silclog.[ch]
2800 * Changed some code to conform new silclog APIs. Affected
2801 files are doc/example_silcd.conf.in, silcd/server.c
2802 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2805 * Fixed a memory leak that could occur in some situations.
2806 Affected file silcd/serverconfig.c.
2808 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2810 * Added the silc_client_del_client to remove the client from
2811 all channels as well. Affected file lib/silcclient/idlist.c.
2813 * Fixed the client library to correctly remove the client
2814 from all channels when the client entry is being destroyed.
2815 Affected file lib/silcclient/client_notify.c, command.c.
2817 * Added auto-nicking support to the client library. If the
2818 applicatio now sets client->nickname it will be sent to the
2819 server after connecting by the library. This way for example
2820 SILCNICK (or IRCNICK) environment variables will have effect
2821 and always change the nickname automatically to whatever
2822 it is wanted. Affected file lib/silcclient/client.[ch].
2824 * Renamed silc_server_command_bad_chars to the
2825 silc_server_name_bad_chars and moved it to the
2826 silcd/server_util.[ch]. Added also new function
2827 silc_server_name_modify_bad to return nickname that
2828 includes bad characters as new nickname without those
2829 bad characters. This check and modify is now used in
2830 silc_server_new_client when the username is initially set
2831 as nickname, so it must be checked to be valid nickname.
2832 Affected file silcd/packet_receive.c.
2834 * The nickname length is now taken from the packet for real
2835 and not trusted to strlen() since it clearly can return
2836 wrong length for nickname including bad characters. This
2837 also applies to channel names. Affected file silcd/command.c.
2839 * Removed the lib/silcsilm/modules directory. Modules are now
2840 compiled into the lib/silcsim. Fixed the copying of the
2841 modules to follow symbolic links in Makefile.am.pre.
2843 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2845 * Fixed silc_string_regexify list creation. Fixes bugs with
2846 BAN and INVITE commands in server. The affected file is
2847 lib/silcutil/unix/silcunixutil.c.
2849 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2851 * Removed the command destructor entirely from the server's
2852 command and command reply routines. It is not needed, and
2853 its usage was buggy and caused crashes. Affected files are
2854 silcd/command[_reply].[ch].
2856 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2858 * Cancel protocol and NULL sock->protocol if timeout
2859 occurred during protocol. Affected file silcd/server.c.
2861 * Cancel protocol timeouts always before calling the final
2862 callback, to assure that after final callback is called
2863 no other state will be called for the protocol anymore.
2864 Affected file silcd/protocol.c.
2866 * Print error log if incoming connection configuration could
2867 not be found. Affected file silcd/server.c.
2869 * Fixed JOIN command to correctly save the founder mode
2870 to the client on normal SILC server, when the channel
2871 was created by the router. Affected file silcd/command.c.
2873 * Fixed LIST command (hopefully) to send correct reply
2874 packets. Affected file silcd/command.c.
2876 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2878 * The silc_packet_receive_process now returns FALSE if the
2879 read data was invalid packet, and TRUE if it was ok.
2881 The server now checks that if unauthenticated connection
2882 sends data and its processing fails the server will close
2883 the connection since it could be a malicious flooder.
2885 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2887 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2889 * Make sure the warning about error opening a log file is
2890 printed only once and not everytime it fails (produces
2891 too much useless log). Affected file lib/silcutil/silclog.c.
2893 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2895 * Made the silc_server_daemonise() function more readable.
2896 Affected file silcd/server.c.
2898 * Pid file is now optional, the user may comment it out from
2899 the config file. Removed define SILC_SERVER_PID_FILE, we
2900 don't need a default any longer. Affected file
2901 configure.in.pre, lib/Makefile.am.pre.
2903 * Make some use of the pid file. The server now dies at startup
2904 if it detects a valid pid file on his path. The server would
2905 die anyway in this circumstance, because of the bind() failure.
2906 Affected file silcd/silcd.c.
2908 * No longer compiling lib/dotconf.
2910 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2912 * Fixed JOIN command parsing not to crash. Affected file
2913 lib/silcclient/command.c.
2915 * Fied the NICK_CHANGE notify to add the new client entry
2916 even it is resolved. This removes an <[unknown]> nick
2917 thingy bug in the client. Affected file is
2918 lib/silcclient/client_notify.c.
2920 * Do not try to allocate 0 bytes (efence does not like it)
2921 in lib/silccore/silccomand.c when encoding payload.
2923 * Do not take IRCNICK as nickname in Irssi SILC client since
2924 it is not possible to set nickname before hand connecting
2925 the server (TODO has an entry about adding auto-nicking
2928 * Changed the silc_server_command_pending to check whether
2929 there already exists an pending entry with the specified
2930 command, command identifier and pending callback. This is
2931 to fix IDENTIFY and WHOIS related crashes that may register
2932 multiple pending commands with same identifier. Affected
2933 file silcd/command.c.
2935 * Fixed the server to reconnect to the router even if it
2936 was already reconnecting and EOF was received. This to
2937 fix a possibility that the server wouldn't ever try to
2938 auto-reconnect to the router. Affected file silcd/server.c.
2940 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2942 * Fixed the server's password authentication to use the
2943 length of the locally saved password, and not the one
2944 sent in the packet. Affected file silcd/protocol.c.
2946 * Fixed same password authentication problem in the
2947 Authentication Payload handling routines in
2948 lib/silccore/silcauth.c.
2950 * Yet another password authentication problem fixed with
2951 channel password handling in silcd/command.c.
2953 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2955 * If first character of string in silc_parse_userfqdn is '@'
2956 then do not parse it. Affected file is
2957 lib/silcutil/silcutil.c.
2959 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2961 * Fixed minor bug in IDENTIFY command reply sending, which
2962 caused various weird problems during JOIN when it was
2963 resolving names for users. Affected file silcd/command.c.
2965 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2967 * Fixed the IDENTIFY command reply sending to chech better valid
2968 clients. It was possible to send incomplete list of replies.
2969 Affected file silcd/command.c.
2971 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2973 * Added silc_client_command[s]_[un]register functions now to
2974 dynamically register the commands in client library. Removed
2975 the static table of commands. This allows the client library
2976 to call commands without causing the application to know about
2977 what commands library has called.
2979 Removed the INFO command reply kludge to detect when the command
2980 was called by library. Now library use its own command reply
2981 function for INFO command.
2983 Added function silc_client_command_call to call a command.
2984 Application can use it to call command, not access the structure
2987 Now all commands that are sent by the client library (not
2988 explicitly sent by application) use own command reply functions.
2990 Affected files around lib/silcclient/ and in
2991 irssi/src/silc/core/.
2993 * Fixed the WHOIS command reply sending to chech better valid
2994 clients. It was possible to send incomplete list of replies.
2996 Fixed the WHOIS and IDENTIFY to send the request to router
2997 if normal server did not do it and did not find any results.
2999 Affected file silcd/command.c.
3001 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3003 * Moved the internal data from SilcClient context into its
3004 own file, not accesible to application. Affected files
3005 lib/silcclient/client.h and lib/silcclient/client_internal.h,
3006 and other files in client library.
3008 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3010 * Added doc/examples installation target in Makefile.am.pre.
3013 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3015 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
3016 commands the found client entry will be removed from the
3017 cache, after notifying application about the error. Affected
3018 file lib/silcclient/command_reply.c.
3020 * Changed the /MSG to check for exact nickname user gave, and
3021 not let `nick' match `nick@host' if it is only one found. Now,
3022 user must type the exact nickname (like nick@host2) even if
3023 there are no more than one same nicks found. This is to avoid
3024 a possibility of sending nickname to wrong nickname since
3025 `nick' could match `nick@host'. Affected file is
3026 irssi/src/core/silc-servers.c.
3028 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3030 * Do not print "you are now server operator" or similar when
3031 giving /away command. Affected files are
3032 irssi/src/silc/core/client_ops.c, silc-servers.h.
3034 * Made the silc_server_command_pending_error_check to send
3035 the same command reply payload it received back to the
3036 original sender of the command. This way all arguments
3037 that was received by the server will be received by the
3038 client too. Affected file silcd/command.c.
3040 * Added the silc_idcache_add to return the created cache entry
3041 to a pointer. Affected file lib/silccore/silcidcache.[ch].
3043 * Add global clients to expire if they are not on any channel.
3044 This is because normal server will never know if they signoff
3045 if they are not on any channel. The cache expiry will take
3046 case of these entries. This is done by normal servers only.
3047 The affected files are silcd/command_reply.c,
3048 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
3050 * If server receives invalid ID notification for WHOIS or
3051 IDENTIFY and the ID exists in the lists, it is removed.
3052 Affected file silcd/command_reply.c.
3054 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
3055 in client then client entry that it matches is searched and
3056 the nickname is printed on the screen for user. Affected
3057 file irssi/src/silc/core/client_ops.c.
3059 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3061 * Use cache entry expire time in the LIST command reply to
3062 purge old entries from the cache after the LIST command
3063 reply has been received. This way we don't have non-existent
3064 entries in the cache for too long. Affected file is
3065 silcd/command_reply.c.
3067 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3069 * If we are normal server, and we've not resolved client info
3070 in WHOIS or IDENTIFY from router, and it is global client,
3071 we'll check whether it is on some channel. If it is not
3072 then we cannot be sure about its validity and will resolve it
3073 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
3074 file silcd/command.c.
3076 * Search channel by name (if possible) rather than by ID
3077 in IDENTIFY command's command reply. Affected file is
3078 silcd/command_reply.c.
3080 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3082 * Distribute to the channel passphrase in CMODE_CHANGE notify.
3083 Updated specs and implemented it. Affected file silcd/command.c,
3084 silcd/packet_send.c and silcd/packet_receive.c.
3086 * Implemented the <founder auth> payload handling in the JOIN
3087 command. If provided all conditions for channel joining
3088 except requirement to provide correct passphrase can be
3089 overrided by the channel founder. Updated the protocol specs.
3090 Affected file silcd/command.c.
3092 Added support for founder auth in JOIN command in client
3093 library. Fixed the parsing of the JOIN command now to support
3094 all options as they should be. The affected file is
3095 lib/silcclient/command.c.
3097 * Optimized the WHOIS and IDENTIFY commands to send the request
3098 to router only if it includes nicknames or other names. If
3099 they include only IDs then check the local cache first before
3100 routing. Affected file is silcd/command.c.
3102 * Added channels topic announcements. Affected file is
3103 silcd/packet_receive.c and silcd/server.c.
3105 * Fixed the silc_server_send_notify_topic_set to really destine
3106 the packet to channel. Affected file silcd/packet_send.c.
3108 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
3109 library. Affected file lib/silcclient/client_notify.c.
3111 * Added UMODE announcements. Affected file silcd/server.c.
3113 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3115 * Memory leak fixes in:
3117 lib/silcutil/silcsockconn.c
3118 lib/silcske/silcske.c
3119 lib/silcske/groups.c
3121 lib/silccrypt/silcpkcs.c
3122 lib/silccore/silccommand.c
3123 lib/silccore/silcidcache.c
3128 * ROBOdoc documented the lib/silcske/groups.h file and a
3129 bit changed the interface for better.
3131 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3133 * Update the client entry context in the ID cache after
3134 nick change. Affected file lib/silcclient/command.c.
3135 Fixes the CUMODE command when regaining founder privileges,
3136 and a little WHOIS problem.
3138 * Fixed silc_net_gethostbyname to correctly call the
3139 inet_ntop. Affected file lib/silcutil/silcnet.c.
3141 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3143 * Added IPv6 support checking to the configure.in.pre, added
3144 also --enable-ipv6 option to override the check. Affected
3145 file configure.in.pre.
3147 * The silc_thread_create now calls the start function
3148 directly if threads support is not compiled in. Removes
3149 ugly #ifdef's from generic code. Affected files are
3150 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
3152 * Added silc_net_gethostby[name/addr]_async to asynchronously

3164 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
3165 routines. Added silc_net_is_ip[4/6]. Affected file is
3166 lib/silcutil/unix/silcunixnet.c. All routines that take
3167 address as argument now supports both IPv4 and IPv6 addresses.
3169 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
3171 * Fixed LIST command reply sending in server. Affected file
3174 * Server now sends the kicker's client ID in the KICK notify
3175 to the kicked client. Affected file silcd/command.c.
3177 * The client library now parses the kickers client ID and
3178 UI displays it. Affected files lib/silcclient/client_notify.c
3179 and irssi/src/silc/core/silc-channels.c, module-formats.c.
3181 * Made all payload parsing function prototypes consistent.
3182 They all take now const unsigned char * and uint32 pair as
3183 the payload data instead of SilcBuffer. Changes all around
3184 the source tree. Other unsigned char* -> const unsigned char*
3185 changes around the tree as well.
3187 * Optimized SFTP client and server packet sending not to
3188 allocate new buffer for each packet but to recycle the
3189 first allocated buffer. Affected files are
3190 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
3192 * Optimized the SFTP client to use SilcList instead of
3193 SilcDList for requests, because it is faster. Affected file
3194 is lib/silcsftp/sftp_client.c.
3196 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
3197 into lib/silccore/silcid.[ch].
3199 Renamed silcpayload.[ch] into silcargument.[ch].
3201 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
3203 * If client entry is deleted with active key agreement
3204 session, abort the session.
3206 The silc_client_abort_key_agreement now calls the completion
3207 callback with new SILC_KEY_AGREEMENT_ABORTED status.
3209 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
3212 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3214 * Don't use __restrict in older GCC's. Affected file is
3215 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
3217 * silc_net_localhost now attempts to reverse lookup the
3218 IP/hostname. Affected file lib/silcutil/silcnet.c.
3220 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
3221 command. It can be used to gain founder privileges at
3222 the same time when joining the channel.
3224 Defined that the SILC_NOTIFY_TYPE_KICKED send the
3225 kicker's client ID as well. Updated protocol specs.
3227 Defined that the server must send SILC_COMMAND_IDENTIFY
3228 command reply with error status to client who sent
3229 private message with invalid client ID.
3231 Updated the protocol specification.
3233 * Added silc_server_send_command_reply to send any
3234 command reply. Affected file silcd/packet_send.[ch].
3236 * Added silc_id_payload_encode_data to encode ID payload
3237 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
3239 * The server now send IDENTIFY command reply with error
3240 status if client ID in private message is invalid. Affected
3241 file silcd/packet_receive.c.
3243 * Save the server key file with server's IP address in
3244 the filename instead of hostname. The affected file is
3245 irssi/src/silc/core/client_ops.c.
3247 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3249 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
3252 * Added libtool support for compiling shared objects in
3253 lib/silcsim. Affected file configure.in.pre and
3254 lib/silcsim/Makefile.am. Original patch by cras.
3256 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3258 * Pid file configuration, and server's config file fixes
3259 patch by toma. Updated CREDITS file.
3261 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3263 * Fixed silc_client_channel_message to not try to decrypt
3264 the message twice if it resolved the destination client
3265 information. This could cause of dropping one channel
3266 message. Affected file lib/silcclient/client_channel.c.
3268 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3270 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3271 lib/silcclient/client.c. This function is used when the SILC
3272 Client is run under some other scheduler, or event loop or
3273 main loop. On GUI applications, for example this may be
3274 desired to used to run the client under the GUI application's
3275 main loop. Typically the GUI application would register an
3276 idle task that calls this function multiple times in a second
3277 to quickly process the SILC specific data.
3279 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3281 * Fixed silc_server_drop() for dropping the supplementary
3282 groups as well, this could cause a security hole on some
3285 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3287 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
3290 * Write PID file after dropping privileges. Added -F option
3291 to run server on foreground. A patch by debolaz.
3292 Affected files silcd/server.c, silcd/silcd.c.
3294 * Fixed MOTD to return the MOTD file server name. Affected
3295 file silcd/command.c.
3297 * Added INFO command reply handling to the Irssi SILC Client.
3298 Affected file irssi/src/silc/core/client_ops.c.
3300 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3302 * Fixed the silc_idcache_list_* routines to really support
3303 the dynamic list. Fixes a crash. Affected file is
3304 lib/silccore/silcidcache.c.
3306 * Fixed the LIST command reply to really call LIST command's
3307 pending callbacks. Affected file silcd/command_reply.c.
3309 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3311 * Update conn->local_entry->nickname after giving NICK
3312 command. Affected file lib/silcclient/command.c.
3314 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3316 * Added the [pid] option to the silcd configuration file
3318 Affected files: serverconfig.[ch] and silcd.c
3320 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3322 * Save fingerprint in WHOIS command reply in server.
3323 Affected file silcd/command_reply.c.
3325 * Fixed NICK commands pending callback registration.
3326 Affected file lib/silcclient/command.c.
3328 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3330 * Use ++server->cmd_ident when sending commands in server,
3331 instead of random number. Affected file silcd/command.c.
3333 * Fixed GETKEY command reply to call actually GETKEY pending
3334 command callbacks. Affected file silcd/command_reply.c.
3336 * A bit stricter check for nicknames. Check for same nickname
3337 in NICK command also. Affected file silcd/command.c.
3339 * Do not call INFO command everytime client ID changes, only
3340 during first connecting. Affected file lib/silcclient/client.c.
3342 * Set the new nickname only after successful command reply for
3343 NICK command is returned by server. Affected file
3344 lib/silcclient/command.c.
3346 * Remove nicknames from nicklist during server_signoff notify.
3347 Should fix /NAMES bit more. The affected file is
3348 irssi/src/silc/core/silc-channels.c.
3350 * Added `fingerprint' field to the SilcIDListData in the
3351 silcd/idlist.h to hold the fingerprint of the client's
3354 Send the fingerprint of the client's public key in WHOIS
3357 Affected files silcd/command.c, and silcd/idlist.[ch].
3359 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3360 create fingerprint from given data.
3362 * Show the fingerprint of the client's public key in WHOIS.
3363 Affected files irssi/src/module-formats.[ch] and
3364 irssi/src/silc/core/client_ops.c.
3366 * Format the multiple same nicknames also during JOIN and
3367 NICK_CHANGE notifys. Affected file is
3368 lib/silcclient/client_notify.c.
3370 * Do not print error on screen for invalid private message
3371 payload since it can come if someone is sending private
3372 messages with wrong key. Affected file
3373 lib/silccore/silcprivate.c.
3375 * Fixed multiple concurrent /PING crash. Affected file
3376 lib/silcclient/command.c.
3378 * Changed the wrong ID encoding. All IP addresses must be
3379 in MSB first order in encoded format. They were encoded
3380 wrong and was in LSB format. Affected files are
3381 silcd/serverid.c, lib/silcutil/silcutil.c.
3383 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3385 * Call the `connect' client operation through the scheduler
3386 in case of error. Affected file lib/silcclient/client.c.
3388 * Call the `failure' client operation even if the error
3389 occurred locally during a protocol. Affected file is
3390 lib/silcclient/protocol.c.
3392 * Added support of sending LIST command to router from normal
3393 server. This way normal server can get list of all channels
3394 in the network too. Fixed the channel list sending in the
3395 server too. Affected files are silcd/command.c, and
3396 silcd/command_reply.[ch].
3398 * Added silc_server_update_channels_by_server and
3399 silc_server_remove_channels_by_server. They are used during
3400 disconnection of primary router and in backup router protocol.
3401 Affected file silcd/server_util.[ch], silcd/server.c and
3402 silcd/server_backup.c.
3404 * Fixed channel adding to global list in IDENTIFY command
3405 reply in server. Affected file silcd/command_reply.c.
3407 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3409 * If the incoming packet type is REKEY or REKEY_DONE process
3410 that packet always synchronously. Fixes yet another MAC
3411 failed error on slow (dialup) connections. Affected file
3412 lib/silcclient/client.c and silcd/server.c.
3414 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3416 * Call check_version SKE callback for initiator too. Affected
3417 file lib/silcske/silcske.c.
3419 * Implemented fix for security hole found in the SKE that was
3420 fixed in the specification few days back; the initiator's
3421 public key is now added to the HASH value computation.
3422 Added backwards support for the old way of doing it too, for
3423 old clients and old servers. Affected file is
3424 lib/silcske/silcske.c.
3426 * Enabled mutual authentication by default in SKE. If initiator
3427 is not providing mutual authentication the responder will
3428 force it. This will provide the proof of posession of the
3429 private key for responder. The affected files are
3430 lib/silcclient/protocol.c and silcd/protocol.c.
3432 * Do not cache anymore the server's public key during SKE.
3433 We do mutual authentication so the proof of posession of
3434 private key is done, and if the server is authenticated in
3435 conn auth protocol with public key we must have the public
3436 key already. Affected file silcd/protocol.c.
3438 * Added new global debug variable: silc_debug_hexdump. If
3439 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3440 file lib/silcutil/silclog.[ch].
3442 * Fixed compilation warning due to char * -> const char *.
3443 Affected files lib/silcutil/silcnet.h, and
3444 lib/silccore/silcauth.[ch].
3446 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3448 * Fixed CMODE command when new channel key was created. If
3449 the creation failed the old key was removed. Next time giving
3450 same command would crash the server since the old key was
3451 freed already. Affected file silcd/command.c.
3453 * Fixed the silc_server_announce_get_channels to not crash
3454 on reconnect. Affected file silcd/server.c.
3456 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3458 * Added silc_log_set_debug_string function to set a regex
3459 string to match for debug output. Only the function names,
3460 or filenames matching the given debug string is actually
3461 printed. This way it is possible to filter out those debug
3462 strings that user is not interested in.
3464 Fixed a bug in silc_string_regexify.
3466 Affected files lib/silcutil/silclog.[ch], and
3467 lib/silcutil/unix/silcunixutil.c.
3469 * Changed the -d options in both server and Irssi SILC client
3470 to take the debug string as argument. Affected files
3471 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3473 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3475 * Added silc_hash_babbleprint to create a Bubble Babble
3476 Encoded fingerprint. The encoding is developed by Antti
3477 Huima (draft-huima-babble-01.txt), and it creates human
3478 readable strings out of binary data. Affected file
3479 lib/silccrypt/silchash.[ch].
3481 * Print the babble print now in addition of fingerprint as well
3482 in Irssi SILC client. Affected files are
3483 irssi/src/fe-common/silc/module-formats.[ch],
3484 irssi/src/fe-common/silc/core/client_ops.c.
3486 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3488 * Fixed a security problem found in SKE. The initiator's
3489 public key too is now added to the HASH hash value creation
3490 which is signed by the responder to create the SIGN value.
3491 This will prevent anyone in the middle to lie to the responder
3492 about the initiator's public key. If this is done now, the
3493 man in the middle will get caught. Updated the protocol
3496 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3498 * Better installation directory handling. Configure module
3499 paths and other paths automatically to example_silc* files
3500 in doc/. A patch by toma.
3502 * Fixed compiler warning from MPI library, and from SILC RNG.
3505 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3506 It can be configured with ./configure. A patch by toma.
3508 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3510 * Find correct make to use in prepare-clean. A patch by
3511 toma. Affected file prepare-clean.
3513 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3515 * Added irssi variables use_auto_addr, auto_bind_ip,
3516 auto_bind_port and auto_public_ip.
3518 * Changed the interface for silc_client_send_key_agreement
3519 in lib/silcclient/silcapi.h
3523 irssi/src/silc/core/silc-core.c
3525 lib/silcclient/silcapi.h
3526 irssi/src/silc/core/silc-channels.c
3527 lib/silcclient/client_keyagr.c
3530 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3532 * Added silc_pkcs_public_key_compare to compare two
3533 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3535 * Check that the client who set the founder mode on the
3536 channel is the same client that is giving the founder
3537 mode to itself. It is done by comparing the saved public
3538 key (it is saved even in the authentication is passphrase).
3539 Affected file silcd/command.c.
3541 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3543 * Do not process packet for disconnected socket connection.
3544 Affected file lib/silccore/silcpacket.c.
3546 * Process the DISCONNECT packet through scheduler in the
3547 client library. Affected file lib/silcclient/client.c.
3549 * Fixed the silc_client_packet_parse to not to increase
3550 the packet sequence number if the conn->sock and the
3551 current socket connection is not same. This can happen
3552 for example during key agreement when the conn includes
3553 multiple socket connections (listeners). Affected file
3554 lib/silcclient/client.c.
3556 * The sender of the file transfer request now provides also
3557 the pointer (listener) for the key exchange protocol. If
3558 the listener cannot be created then it sends empty key
3559 agreement and lets the receiver provide the listener.
3561 Added `local_ip' and `local_port' arguments to the
3562 silc_client_file_send. If they are provided they are used,
3563 if not then it will attempt to find local IP address, if
3564 not found or bind fails then the remote client will provide
3567 Affected files are lib/silcclient/client_ftp.c and
3568 lib/silcclient/silcapi.h.
3570 * Extended the FILE SEND command to support defining the
3571 local IP and port for key exchange listener. They are
3572 optional. Affected file irssi/src/silc/core/silc-servers.c.
3574 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3576 * Defined to WHOIS command reply the sending of fingerprint
3577 of the client's public key (if the proof of posession of the
3578 corresponding private key is verified by the server).
3579 Updated to the protocol specification.
3581 * Added support of receiving the client's public key's
3582 fingerprint in command reply in client library. Affected
3583 file is lib/silcclient/command_reply.c, and
3584 lib/silcclient/idlist.[ch].
3586 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3588 * Do not send over 128 chars long nickname to the server
3589 in NICK command. Affected file lib/silcclient/command.c.
3591 * Do not send over 256 chars long channel names to the server
3592 in JOIN command. Affected file lib/silcclient/command.c.
3594 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3596 * Assure that silc_server_close_connection cannot be called
3597 twice for same socket context. Affected file is
3600 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3602 * Send error message to application if opening file for
3603 writing during file transfer fails. Affected file is
3604 lib/silcclient/client_ftp.c.
3606 Remove all file transfer sessions for a client that we're
3607 removing from ID cache.
3609 Affected file is lib/silcclient/client_ftp.c.
3611 * Fixed silc_net_addr2bin to return correct address. Affected
3612 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3614 * Fixed file transfer session removing on signoff notify.
3615 Affected file irssi/src/silc/core/silc-servers.c.
3617 * Added the SilcClientFileError to be returned in the monitor
3618 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3619 Affected file lib/silcclient/silcapi.h.
3621 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3623 * Fixed a crash in silc_client_ftp_free_sessions and
3624 silc_client_ftp_session_free_client. Affected file
3625 lib/silcclient/client_ftp.c.
3627 * Added `disabled' field in the SilcChannelEntry in the server
3628 to indicate if the server entry is disabled. Affected file
3629 silcd/idlist.h, silcd/command[_reply].c.
3631 * SILC server adds now /var/run/silcd.pid everytime it is
3632 started. Affected file silcd/silcd.c.
3634 * Added silc_server_packet_send_clients to send a packet to
3635 the provided table of client entries. Affected file
3636 silcd/packet_send.[ch].
3638 * Fixed a crash in client resolving in client_prvmsg.c in
3639 client library. Affected file lib/silcclient/client_prvmsg.c.
3641 * Do not actually remove the client directly from ID cache
3642 during SERVER_SIGNOFF, but invalidate it. This way we
3643 preserve the WHOWAS info for the client. Affected file
3644 silcd/server_util.c.
3646 * Fixed SERVER_SIGNOFF notify handling in the server. The
3647 server is now able to process incoming SERVER_SIGNOFF notify
3648 for a server that it doesn't even know about. It will remove
3649 the clients provided in the notify. Affected file
3650 silcd/packet_receive.c.
3652 * Check for partial packet in data queue after every packet that
3653 was found from the queue. Return and wait for more data if
3654 there is partial data in queue. Affected file is
3655 lib/silccore/silcpacket.c.
3657 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3659 * Added SilcClietFileError enum to indicate error in
3660 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3661 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3662 Affected files lib/silcclient/silcapi.h and

3666 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3668 * Added better monitor of file transfers. It now monitors
3669 key agreement protocol during the file transfer too. Added
3670 error reporting too. Affected files
3671 irssi/src/silc/core/silc-servers.c,
3672 irssi/src/fe-common/silc/module-formats.[ch].
3674 * Wrote a help file for FILE command.
3676 * Added silc_rng_global_get_byte_fast to get not-so-secure
3677 random data as fast as possible. Random data is read from
3678 /dev/urandom if available and from the SILC RNG if not
3679 available. It is used in padding generation. Affected file
3680 lib/silccrypt/silcrng.[ch].
3682 * All packets in client library are now processed synchronously.
3683 Optimized packet processing a lot. Affected file
3684 lib/silcclient/client.c.

3695 * Assure that silc_client_notify_by_server_resolve does not
3696 resolve the client information multiple times. If it cannot
3697 be found by the first it cannot be found at all. Affected
3698 file lib/silcclient/client_notify.c.
3700 * Fixed WHOWAS command reply calling. Affected file
3701 lib/silcclient/command_reply.c.
3703 * Removed all references to silc_idlist_get_client from the
3704 Irssi SILC client since that call is internal call used by
3705 the library. The Irssi SILC client will use now client
3706 retrieval functions found in silcapi.h.
3708 * Fixed a bug in resolving nickname info before sending
3709 private message. It used freed memory. Affected file
3710 irssi/src/silc/core/silc-servers.c.
3712 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3714 * Assure my_channels statistics cannot go negative in server.
3715 Affected files silcd/server.c, silcd/server_util.c.

3731 * Added silc_net_localip to return local host's IP address.
3732 Affected file lib/silcutil/silcnet.[ch].
3734 * If key exchange or rekey protocol is active for a connection
3735 parse all packets syncronously since there might be packets
3736 in packet queue that we are not able to process without first
3737 processing packets before them. Affected file silcd/server,
3738 lib/silcclient/client.c.
3740 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3741 whether library should continue processing the packet.
3742 Affected file lib/silccore/silcpacket.h.

3773 lib/silcutil/silcutil.[ch].
3775 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3777 * Resolve the client info when received private message or
3778 channel message for a client which nickname we don't know.
3779 Affected files lib/silcclient/client_prvmsg.c and
3780 lib/silcclient/client_channel.c.

3788 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3789 is incomplete and is being resolved, it won't be resolved
3792 Make sure also that USERS command reply does not resolve
3793 twice information. Affected file is
3794 lib/silcclient/command_reply.c.
3796 Make sure that silc_client_get_clients_by_list does not
3797 resolve twice same information.
3799 * Check for valid client->id in the silc_server_free_client_data.
3800 Affected file silcd/server.c.
3802 * Fixed /GETKEY nick@server not to crash if the server entry
3803 is not found. Affected file lib/silcclient/command.c.
3805 * Fixed the silc_server_check_cmode_rights to check the
3806 requested modes correctly. Affected file silcd/command.c.

3811 Affected file silcd/command.c.
3813 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3815 * Call the silc_server_udpate_servers_by_server in the
3816 primary router that comes back online in the backup resuming
3817 protocol. Otherwise it routes packets wrong. Affected file
3818 silcd/server_util.[ch], silcd/server_backup.c.
3820 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3822 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3823 lib/silcutil/silcbuffmt.[ch].
3825 * Redefined the SILC packet header to include the padding
3826 length. Affected file lib/silccore/silcpacket.[ch].
3828 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3829 length for maximum padding up to 128 bytes). Affected
3830 file lib/silccore/silcpacket.h.
3832 * Removed all backwards support for old 0.5.x MAC thingies.
3833 The SILC packet header change makes it impossible to be
3834 backwards compatible.
3836 * Send the ENDING packet with timeout in the backup resuming
3837 protocol. This is to assure that all routers has connected
3838 to the primary router. Affected file silcd/server_backup.c.
3840 * Changed the RNG to take the first IV from random data. It
3841 used to take it from zero actually. Changed the RNG also
3842 to use /dev/urandom during session. /dev/random is used
3843 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3845 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3847 * Changed the SILC packet header to have the first two bytes
3848 (the packet length) encrypted. Affected files aroung the
3849 code tree, lib/silccore/silcpacket.[ch]. Removed the
3850 SilcPacketCheckDecrypt callback. It is not needed anymore
3851 since the silc_packet_receive_process will determine now
3852 whether the packet is normal or special.
3854 * Implemented the unidirectional MAC keys. Affected files
3855 lib/silcske/silcske.c, silcd/protocol.c and
3856 lib/silcclient/protocol.c.
3858 * Implemented the packet sequence number to the MAC computation.
3859 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3860 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3861 lib/silcclient/protocol.c.
3863 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3865 * Allow backup router to announce servers. All servers
3866 announced by backup router are added to the global list
3867 automatically. Update hte server's socket to our primary
3868 router also when backup router announces a server.
3869 Affected file silcd/packet_receive.c.
3871 * Do not update the client->router in the function
3872 silc_server_udpate_clients_by_server if the client is on
3873 global list. We might fail to find any specific server
3874 for locally connected clients and local cell clients. They
3875 should still use the `from' and not `to' as client->router.
3876 This fixes backup router resuming protocol. Affected file
3877 silcd/server_util.c.
3879 * Decrease channel statistics count only if the channel
3880 deletion worked. Affected files are silcd/server.c and
3881 silcd/server_util.c.
3883 * Added silc_server_update_servers_by_server to update origin
3884 of all server entries. Used during backup router protocol.
3885 Affected files silcd/server_util.[ch], silcd/server.c. and
3886 silcd/backup_router.c.
3888 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3889 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3890 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3891 lib/silccrypt/silchmac.c.
3893 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3895 * Assure that router cannot reroute the same channel message
3896 to the sender. Affected file silcd/packet_receive.c.
3898 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3900 * Made better checks that the channel message is not sent
3901 to the router it came from. Affected file is
3902 silcd/packet_send.c. Fixed memory leak too.
3904 * Announce informations for incoming router connection, but
3905 only after checking if it is replaced by backup router.
3906 Affected file silcd/packet_receive.c.
3908 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3910 * Fixed the backup resuming protocol to work in multiple
3911 router environment. Affected file silcd/server_backup.c.
3913 * Route packet only to one router in the function
3914 silc_server_packet_send_to_channel. Affected file is
3915 silcd/packet_send.c.
3917 * Fixed silc_server_send_notify_dest to set the broadcast
3918 flag. Fixed the silc_server_send_notify_topic to actually
3919 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3920 Affected file silcd/packet_send.c.
3922 * Changed the SFTP Filesystem interface. Changed the
3923 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3924 the filesystem operation function. The SilcSFTPFilesystem
3925 is now a context that is allocated by all filesystem allocation
3926 functions and it already includes the operations structure
3927 and filesystem specific context. It is given as argument
3928 now to the silc_sftp_server_start. This made the interface
3929 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3930 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3932 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3934 * Changed the backup router adding and getting interfaces
3935 in the server. The router that will be replaced by the
3936 specified backup router is now sent as argument. Affected
3937 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3940 * Added silc_net_addr2bin_ne to return the binary form of
3941 the IP address in network byte order. Affected files
3942 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3944 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3946 * Check for existing server ID in silc_server_new_server
3947 and in silc_server_connect_to_router_final and remove the
3948 old entry if it exists. Affected file silcd/packet_receive.c,
3951 * Send the channel message always to only one router, either
3952 in upstream or downstream. Affected file is
3953 silcd/packet_send.c.
3955 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3957 * Wrote the definition of the backup resuming protocol to the
3958 protocol specification.
3960 * Removed one redundant channel key generation from normal
3961 server during joining procedure. Removed one redundant
3962 channel key sending from server to router during joining
3963 procedure. Affected file silcd/command.c.
3965 * Made minor bugfixes to the backup router resuming protocol.
3966 Affected file silcd/server_backup.c, server.c.

3971 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3974 * Implemented the backup resuming protocol that is used to
3975 resume the primary router position in the cell after the
3976 primary router comes back online. Affected files
3977 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3978 and silcd/server_util.[ch].
3980 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3982 * Sleep two (2) seconds after sending QUIT command to server.
3983 Affected file lib/silcclient/command.c.
3985 * Assure that if outgoing data buffer is pending do not force
3986 send any data. Affected file silcd/packet_send.c.
3988 * Assure that if outgoing data buffer is pending do not force
3989 send any data. Affected file lib/silcclient/client.c.
3991 * Implemented the backup router support when the primary router
3992 goes down. The servers and routers can now use the backup
3993 router as new primary router without loosing connectivity.
3995 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3997 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3998 in the server to indicate disabled entry. All data read
3999 from the connection will be ignored and no data is sent
4000 for entry that is disabled. Affected files are
4001 silcd/idlist.h, silcd/server.c.
4003 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4005 * Created SFTP client and server test programs in the
4006 lib/silcsftp/tests directory.
4008 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
4010 * Implemented memory filesystem (virtual filesystem) for
4011 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
4014 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4016 * Implemented the SFTP (SSH File Transfer Protocol) to the
4017 lib/silcsftp. It includes SFTP client and SFTP server
4020 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4022 * Moved lib/silccore/silcprotocol.[ch] to the
4023 lib/silcutil library.
4025 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
4026 take variable argument list pointer as argument. Affected
4027 file lib/silcutil/silcbuffmt.[ch].
4029 * Added silc_buffer_set function that is used to set data
4030 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
4031 Affected file lib/silcutil/silcbuffer.h.
4033 * Changed various routines in the core library to use the new
4034 silc_buffer_set instead of allocating new buffer only for
4037 * Added 64-bit value formatting and unformatting support to the
4038 silc_buffer_[un]format routines. Affected file is
4039 lib/silcutil/silcbuffmt.[ch].
4041 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
4042 to includes/bitmove.h.
4044 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4046 * Fixed channel user mode saving in client library. Affected
4047 file lib/silcclient/command[_reply].c.
4049 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4051 * Defined the file transfer to the SILC Protocol. Added
4052 new packet type SILC_PACKET_FTP and defined File Transfer
4053 Payload. The mandatory file transfer protocol is SFTP
4054 (SSH File Transfer Protocol). Affected file in addition
4055 of the internet draft is lib/silccore/silcpacket.h.
4057 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
4058 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
4059 is used as part of backup router protocol when the primary
4060 router of the cell is back online and wishes to resume
4061 the position as primary router.
4063 * Redefined the MAC generation keys in the protocol. The
4064 same key is not used anymore in both direction. Both
4065 direction will now use different keys for sending and
4066 receiving. This fixes a potential security flaw. This
4067 change causes incompatibilities in the protocol.
4069 * Redefined also the MAC computation from the packet.
4070 An packet sequence number is now added to the MAC
4071 computation. This prevents possible replay attacks against
4072 the protocol. This change too causes incompatibilities
4075 Added `sequence' field to the SilcPacketContext to hold
4076 the current sequence number for the packet.
4078 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4080 * Added `created' field to the SilcIDListData in the file
4081 silcd/idlist.h to indicate the time when the entry was
4084 * Added `created' field to the SilcChannelEntry too. Affected
4085 file silcd/idlist.h.
4087 * Added `creation_time' aguments to all the announcement functions
4088 in the server. If it is provided then only the entries that
4089 was created after the provided time frame are actually
4090 announced. Affected file silcd/server.[ch].
4092 * The protocol says that the Channel ID's IP address must be
4093 based on the router's IP address. Added check for this in
4094 the silc_server_new_channel when processing incoming New Channel
4095 Payload. Affected file silcd/packet_receive.c.
4097 * Print out the correct version with --version in SILC client.
4098 Affected file irssi/src/silc/core/silc-core.c.
4100 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4102 * Fixed WHOWAS command to check for completnes of the client
4103 entry always, not just when the command is coming from client.
4104 Affected file silcd/command.c.
4106 * Added new function silc_server_packet_queue_purge to purge the
4107 outgoing data queue to the network. After the function returns
4108 it is guaranteed that the outgoing packet queue is empty.
4109 Affected file silcd/packet_send.[ch].
4111 * Purge the outgoing packet queue in the rekey protocol's final
4112 callback to assure that all rekey packets go to the network
4113 before quitting the protocol. Affected file silcd/server.c.
4115 * Added silc_client_packet_queue_parse as similar function as
4116 in server to the client library. The affected file is
4117 lib/silcclient/client.c.
4119 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4121 * Splitted silcd/server.c and created silcd/server_util.[ch]
4122 for utility functions.
4124 * Added new socket flag SILC_SF_DISABLED to indicate that the
4125 connection is open but nothing can be sent to or received from
4126 the connection. Affected file lib/silcutil/silsockconn.[ch].
4127 The checking for disabled socket is checked in the low level
4128 silc_socket_write and silc_socket_read functions.
4130 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4132 * Allow only nicknames and channel names that fits into the
4133 7-bit unsigned char ASCII set. Affected file silcd/command.c.
4135 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4137 * When processing JOIN command reply in server check that if
4138 the channel exists in our global list we'll move it the local
4139 list. Affected file silcd/command_reply.c.
4141 * Fixed the check whether client is joined on the channel already
4142 in JOIN command. Affected file lib/silcclient/command.c.
4144 * Fixed the JOIN command reply to check whether the channel
4145 already exists. Affected file lib/silcclient/command_reply.c.
4147 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4149 * Added silc_ske_status_string to map the SKE error numbers
4150 to readable strings. The affected files are
4151 lib/silcske/silcske[_status].[ch].
4153 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4155 * Do not show the private channels on the WHOIS channel list
4156 as it is not allowed by the protocol. The affected file is
4159 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4161 * Assure that the packet length digged from the actual packet
4162 is something sensible in the silc_packet_decrypt_rest_special
4163 in lib/silccrypt/silcpacket.c.
4165 * Free and NULL the allocated pointer in silc_hmac_alloc if
4166 the HMAC allocation fails. The affected file is
4167 lib/silccrypt/silchmac.c.
4169 * Print the selected security properties to the log files in
4170 the server. Affected file silcd/protocol.c.
4172 * Add SKE's reference counter even if calling the completion
4173 callback manually. Otherwise it goes negative, although it
4174 does not cause any problems. The affected file is
4175 lib/silcske/silcske.c.
4177 * Remove the client entry with short timeout after giving the
4178 KILL command. Affected file lib/silcclient/command.c.
4180 * Fixed to send error reply in WHOIS and IDENTIFY commands in
4181 case all found clients are already disconnected (WHOWAS would
4182 found them) in the server. Affected file silcd/command.c.
4184 * Update the last_receive (time of last data received) to be
4185 updated only when received private or channel message so that
4186 the idle time showed in WHOIS makes more sense.
4188 * Added boolean field `valid' in to the SilcClientEntry in the
4189 client library to indicate whether the entry is valid or not.
4190 This fixes the nickname change bug on channel when changing
4191 the nickname to be same than the old (like nick to Nick) the
4192 nickname formatter doesn't set the new nick anymore to Nick@host.
4193 Affected file lib/silcclient/idlist.[ch].
4195 * Now actually fixed the nickname changing on disconnection.
4196 Added new function silc_change_nick to the Irssi SILC Client.
4197 Affected file irssi/src/silc/core/client_ops.c,
4198 irssi/src/silc/core/silc-nicklist.[ch].
4200 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4202 * Check that the public key exists in the GETKEY command before
4203 trying to encode it. Affected file silcd/command.c.
4205 * Print some notifications on received public keys with GETKEY
4206 command in the Irssi SILC Client. Affected files are
4207 irssi/src/fe-common/silc/module-formats.[ch],
4208 irssi/src/silc/core/client_ops.c.
4210 * Use IDENTIFY command to resolve the server information in the
4211 GETKEY command instead of INFO command. Affected file
4212 lib/silcclient/command.c.
4214 * All command reply functions in the client library now calls
4215 the pending command reply callbacks even if an error has
4216 occurred. The server has done this a long time and now it was
4217 time to move the client library to this as well. Now all
4218 errors can be delivered back to the pending command reply
4219 callbacks if necessary. Affected files are
4220 lib/silcclient/command[_reply].[ch].
4222 * Change the nickname on disconnection back to the username
4223 because in reconnect the server will enforce it to it anyway.
4224 Affected file irssi/src/silc/core/silc-servers.c.
4226 * Fixed a config file parsing bug in the Irssi SILC client.
4227 Affected file irssi/src/silc/core/clientconfig.c.
4229 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4231 * When printing the channel mode on JOIN, verify that the
4232 channel key and channel's HMAC are valid. Affected file
4233 irssi/src/silc/core/client_ops.c.
4235 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4237 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
4238 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
4239 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
4241 * Removed channel key rekey task deleting from the function
4242 silc_server_save_channel_key. Affected file silcd/server.c.
4243 Added explicit timeout task context instead that is used to
4244 delete the task if we are registering a new task before the
4245 new task has elapsed.
4247 * When channel key rekey occurs the client library now saves
4248 the old channel key for a short period of time (10 seconds) and
4249 is able to use it in case some is still sending channel
4250 messages encrypted with the old key after the rekey. Affected
4251 file lib/silcclient/[idlist.h|client_channel.c].
4253 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4255 * Added check to the silc_server_new_id_real to not accept
4256 new ID if it is the sender's own ID. Affected file is
4257 silcd/packet_receive.c.
4259 * Assure that we do not announce ourself or the one we've
4260 sending our announcements when we're router and are announcing
4261 servers to our primary router. Affected file silcd/server.c.
4263 * Fixed silc_server_command_identify_check_client to assemble
4264 correct WHOIS packet. It send corrupted WHOIS packet and
4265 caused problem with router to router connections. Affected
4266 file silcd/command.c.
4268 Fixed also silc_server_command_whois_check the same way
4269 as for the IDENTIFY command.
4271 * Added new SilcIDListStatus to the server in the SilcIDListData
4272 structure. The status now includes the current status of
4273 the entry (like registered, resolved etc.). Affected file
4274 silcd/idlist.[ch]. Defined a bunch of different status types
4275 as well. This replaced the old boolean registered field as well.
4277 Added resolve_cmd_ident field to the SilcClientEntry structure
4278 too so that if the entry is for example being resolved so
4279 another command may attach to the same pending command reply
4280 without requiring to resolve the same entry again. This concept
4281 should optimize the WHOIS and the IDENTIFY resolving under
4282 heavy load by taking away unnecessary resolving for entries
4283 that are being resolved already.
4285 Added support for adding multiple pending commands for one
4286 command idenfier. Affected file silcd/command[_reply].[ch].
4288 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4289 before deleting the data. Otherwise the hash table will have
4290 freed data in comparison functions. Affected file is
4291 silcd/command_reply.c.
4293 * Fixed silc_idlist_replace_client_id to add the new entry to
4294 the cache with NULL nickname. Otherwise there will be invalid
4295 memory as the nickname after the nickname is freed. Affected
4296 file silcd/packet_receive.c.
4298 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4299 saved into wrong slots because the previous number of entries
4300 was not taken into account. Affected file silcd/idlist.c.
4301 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4303 * If we are router and we receive JOIN notify to a channel that
4304 does not have any users then notified client is marked as the
4305 channel founder, as it is it. The affected file is
4306 silcd/packet_receive.c
4308 * Added to the extended hash table API's table_del_*ext functions
4309 the destructor as argument too, so that the caller can decide
4310 which destructor to use or whether to use destructor at all.
4311 Affected file lib/silcutil/silchashtable.[ch].
4313 * Fixed ID Cache purging. It actually deleted the entries from
4314 the hash table after the data was freed. The hash table ended
4315 up comparing freed memory. The affected file is
4316 lib/silccore/silcidcache.c.
4318 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4320 * Fixed Irssi SILC client's KILL command's HELP syntax.
4322 * The USERS command now resolves the detailed user information
4323 if the userinfo field is missing. Affected file is
4324 lib/silcclient/command_reply.c.
4326 * Do not print error in silc_file_read if the read file does
4327 not exist. Just silently return NULL. Affected file is
4328 lib/silcutil/silcutil.c.
4330 * Fixed the silc_log_output to not wine about NULL filename
4331 and to not create some bogus " " filename. Affected file is
4332 lib/silcutil/silclog.c.
4334 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4336 * Fixed various printing bugs on the user interface in the
4337 Irssi SILC Client. Minor changes that were forgotten from
4340 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4342 * Fixed the configure.in.pre and the compilation and distribution
4343 environment to support the new autoconf 2.52. That version is
4344 now required to compile the CVS trunk.
4346 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4348 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4349 to generally parse user@fqdn format strings. Affected file
4350 lib/silcutil/silcutil.c.
4352 * Added nickname_format and nickname_force_format fields to the
4353 SilcClientParams structure. The first one defines the format
4354 for the nicknames that the library will enforce if the receives
4355 multiple same nicknames. The second one is boolean value and
4356 can be used to force the library to always enforce the format
4357 to the nicknames regardles whether there are multiple nicknames
4358 or not. This configurable formatting was employed to flexibly
4359 support accessing multiple nicknames from the user interface.
4360 The userinterface can now set the nicknames to what ever format
4361 they prefer. Affected file lib/silcclient/silcapi.h.
4363 Added function silc_client_nickname_format to the file
4364 lib/silcclient/idlist.c. It performs the nickname formatting.
4366 Added new field `hostname´ to the SilcClientEntry context.
4367 It holds the hostname of the client. Affected file is
4368 lib/silcclient/idlist.h.
4370 * Irssi SILC Client sets the nicknames in nick@hostn format.
4371 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4372 irssi/src/silc/core/silc-core.c.
4374 The WHOIS printing now also shows both the real nickname and
4375 the formatted nickname so that user knows how to access the
4376 user if there are multiple same nicknames cached. Affected
4377 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4378 printing formatting too to take the hostname now as a separate
4379 argument. The Affected file is
4380 irssi/src/fe-common/silc/modules-formats.[ch].
4382 * Changed the silc_client_get_clients_local to accept the formatted
4383 nickname as argument. It accepts the real nickname too but the
4384 formatted nickname can be used to find the true entry from
4385 multiple entries. Affected file lib/silcclient/silcapi.h and
4386 lib/silcclient/idlist.c.
4388 * Added nickname_format_parse field to the SilcClientParams.
4389 It is a callback function provided by the application to parse
4390 the nickname out of the formatted nickname string. The library
4391 calls it to get the nickname from the formatted string. Since
4392 the application generally knows better the format of the nickname
4393 string it parses it instead of the library, even though library
4394 encodes the formatted string. If the callback function is not
4395 provided then the library will use the string as is. The
4396 affected file is lib/silcclient/silcapi.h.
4398 * All the nickname strings passed to the client library in
4399 commands are now expected to be formatted nickname strings.
4400 If the command does not support the formatted nickname string
4401 it will assume that the sent string is the actual nickname.
4402 Affected file lib/silcclient/command.c.
4404 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4406 * Added public key authentication support to OPER and SILCOPER
4407 commands in the client library. Affected file is
4408 lib/silcclient/command.c.
4410 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4412 * Changed the get_auth_methdod client operation to be asynchronous.
4413 It can be async if the application resolves the authentication
4414 method from the server during the negotiation. Added new
4415 SilcGetAuthMeth completion callback that the application will
4416 call after resolving the authentication method.
4418 Added function silc_client_request_authentication_method that
4419 the application can use to resolve the authentication method
4420 from the server. Added also SilcConnectionAuthRequest callback
4421 that the library will call after the server has replied. The
4422 application can call this function if it does not know the
4423 current authentication method.
4425 Affected files are lib/silcclient/client.c and
4426 lib/silcclient/silcapi.h.
4428 * The Irssi SILC client now automatically resolves the authentication
4429 method incase any configuration information is not present (and
4430 currently there never is). The affected file is
4431 irssi/src/silc/core/client_ops.c.
4433 * Fixed public key authentication from the client library.
4434 Affected file lib/silcclient/protocol.c. Changed also the
4435 protocol specification about the public key authentication in
4436 the connection authentication protocol. The actual data to be
4437 signed is now computed with a hash function before signing.
4439 * Fixed the public key authentication from the server as well.
4440 Affected file silcd/protocol.c.
4442 * Removed the mlock()'s from the memory allocation routines.
4443 Affected file lib/silcutil/silcmemory.c. The ./configure does
4444 not check anymore for the mlock(). Affected file is
4447 * Fixed USERS command in server to allow the execution of the
4448 command for private and secret channels if the client sending
4449 the command is on the channel. Affected file silcd/command.c.
4451 * Fixed silc_client_get_clients_local to return the clients
4452 count correctly. It could return wrong value. Affected file
4453 lib/silcclient/idlist.c.
4455 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4457 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4458 types. The assembler optimizations seemed not to like 64-bit
4459 data types. The assmebler optimizations thus are now enabled
4460 also for BSD systems as opposed to only enable them for Linux.
4462 * Do not check for threads at all on BSD systems. Affected
4463 file configure.in.pre.
4465 * Removed -n and -h options from the Irssi SILC Client since
4466 they are not used in silc.
4468 * Fixed the prime generation to assure that the first digit
4469 of the generated random number is not zero since our conversion
4470 routines does not like number strings that starts with zero
4471 digit. If zero digit is seen the random number is regenerated.
4472 This caused some corrupted RSA keys when the zero first digit
4473 was met. Affected file lib/silcmath/silcprimegen.c.
4475 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4477 * Fixed WIN32 configuration in the ./configure script.
4478 Fixed to include xti.h on environments that has it.
4479 Patches by Carsten Ilchmann and andrew.
4481 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4483 * Changed the silc_id_create_client_id to be collision
4484 resistant. It is now assured that there cannot be created
4485 two same client ID's. I suspect that some weird bugs in
4486 the server were actually caused by duplicate Client IDs.
4487 Affected file silcd/serverid.[ch]. A router receiving
4488 new ID now also assures and informs the sending server
4489 if the ID caused collision.
4491 * Changed the silc_id_create_channel_id to also assure that
4492 there are no collisions.
4494 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4496 * Statement about ignoring the Mutual Authentication flag when
4497 performing rekey with PFS was a bit misleading. It is ignored
4498 if it was set in the initial negotiation, it cannot be even
4499 set in the rekey. Fixed in the ke-auth draft. Started the
4500 new versions of the protocol drafts in the doc/.
4502 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4504 * Fixed a bug in silc_client_command_identify_save when saving
4505 new channel information. The channel name was no duplicated
4506 and caused crash on exit. Affected file is
4507 lib/silcclient/command_reply.c.
4509 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4511 * Fixed the getkey command handling in the server. Send just
4512 empty OK reply to the sender if the key could not be fetched
4513 (but everything else was ok, like the key just was not available).
4514 Changed the public key parameter to optional in the protocol
4515 specs so that empty OK reply can be sent. Affected file
4518 Added a message to Irssi SILC client to tell to user if the
4519 server did not return a public key.
4521 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4523 * Fixed a channel key regeneration bug. It registered new
4524 timeout tasks exponentially until all system resources were
4525 used. Affected file silcd/server.c.
4527 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4529 * Added the SILC Document generator to the scripts/silcdoc.
4530 It can be used to generate the Toolkit Reference Manual out
4531 of the source tree. Internally it will also use the RoboDoc
4532 generator now imported in util/robodoc.
4534 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4536 * Added couple of return's in rekey protocol if error orccurred
4537 during the protocol. The execution must be terminated.
4538 Affected file silcd/protocol.c. Also, terminate the protocol
4539 always with timeout.
4541 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4543 * The client's Client ID was created initally from the wrong
4544 nickname (it could have been in format nick@host) in the
4545 silc_server_new_client. Affected file silcd/packet_receive.c
4547 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4549 * Added some SILC_LOG_ERROR's to various error conditions
4550 if client could not be added to ID cache. Affected files
4551 silcd/packet_receive.c and silcd/server.c.
4553 * When client's sock->user_data is freed, NULL also the
4554 client->router and client->connection pointers. Added check
4555 for these pointers being NULL to various places around the
4556 code. Affected file silcd/server.c.
4558 * Added client->data.registered == TRUE checks to various
4559 places around the code to assure that unregistered client's
4560 are not handled when it is not allowed. Affected file
4563 * Added `bool registered' fields to all
4564 silc_idlist_[server|client]_get_* routines to indicate whether
4565 the fetched client needs to be registered or not. Affected
4566 file silcd/idlist.[ch].
4568 * Add your own entry as registered to the ID cache in the
4569 server. Affected file server.c.
4571 * Fixed a bug in silc_server_new_server. The SilcServer was
4572 set as the new server's context instead of SilcServerEntry.
4573 This naturally caused some weird bugs.
4575 * Added "updated" field the SilcChannelEntry which indicates
4576 the time since the channel entry was last accessed. This
4577 can be used to determine whether it is necessary to
4578 announce the channel after backup resuming protocol.
4579 Affected files silcd/idlist.[ch].
4581 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4583 * Do not delete the channel rekey task when adding it
4584 for in silc_server_create_channel_key.
4586 * Changed the silc_server_create_channel_key to return
4587 TRUE or FALSE to indicate the success of the channel key
4590 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4592 * Fixed MSVC++ project files and added missing files to
4593 Makefiles under win32/.
4595 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4597 * Do not add TCP_NODELAY flag if the operating system
4598 does not have it defined. Affected files are
4599 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4601 * Fixed buffer overflow from Irssi SILC Client. Affected
4602 file irssi/src/fe-common/core/themes.c.
4604 * Fixed double free in client library in the file
4605 lib/silcclient/client.c when disconnecting from server.
4607 * Applied double free patch from cras to Irssi SILC client.
4608 Affected files irssi/src/core/[modules/expandos].c
4610 * Fixed the disconnection handling to Irssi SILC Client.
4611 The application must call silc_client_close_connection
4612 in ops->connect client operation in case of failure of
4613 the connection. Affected file is
4614 irssi/src/silc/core/client_ops.c.
4616 * Do not set sock->protocol to NULL in the function
4617 silc_client_close_connection after executing the protocol's
4618 final callback since the sock might not be valid anymore.
4619 Affected file lib/silcclient/client.c.
4621 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4623 * Do not enable SILC_THREADS if the linking with libpthread
4624 did not happen. Affected file configure.in.pre.
4626 * Added notion to protocol specification that server must
4627 verify the sent authentication payload with CMODE when
4628 setting the channel founder key. Implemented it to the
4629 server. Affected file silcd/command.c.
4631 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4633 * Added _EXTRA_DIST SILC distribution variable to the
4634 distributions file. It is used to conditionally add extra
4635 files or directories to the specific distribution. Affected
4636 files ./prepare, Makefile.am.pre and distributions.
4638 Removed the `_' from the start of the distribution names.
4641 * Added README.WIN32 for instructions to compile the Toolkit
4644 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4646 * Fixed a double free in disconnection in the server. Affected
4647 file is silcd/server.c.
4649 * Fixed the lib/silcske/groups.c to work now also with GMP
4650 MP library. The string conversion did not work when using
4651 specific base and the base is indicated in the string as well.
4653 * Created win32/ directory which now includes MSVC++ specific
4654 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4655 It will appear only in the toolkit distribution
4657 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4659 * Changed the key material distribution function in case when
4660 the hash output is too short. The data is now concatenated
4661 a bit differently than it used to. Made the change to the
4662 SKE protocol specification.
4664 * Added better GMP detection to configure.in.pre. A patch
4667 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4669 * Fixed a minor bug in SKE that might cause some problem on
4670 some platforms. Affected file lib/silcske/silcske.c.
4672 * Added the cookie checking for initiator in the SKE. It checks
4673 that the responder returns the sent cookie unmodified. The
4674 affected file is lib/silcske/silcske.c. Added new SKE
4675 error type INVALID_COOKIE that can be sent during the
4676 negotiation. Fixed some memory leaks as well.
4678 * Added the "invalid cookie" error message to Irssi SILC client's
4681 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4683 * Added `task_max' field to the SilcClientParams to indicate
4684 the maximum tasks the scheduler can handle. If set to zero,
4685 default values are used. Affected file lib/silcclient/silcapi.h.
4687 * Fixed memory leaks in silc_client_close_connection. Affected
4688 file lib/silcclient/client.c.
4690 * Added silc_client_del_client_entry to client library to free
4691 all memory of given client entry. Affected file is
4692 lib/silcclient/idlist.[ch].
4694 * Added new functions silc_client_del_channel and
4695 silc_client_del_server to delete channel and server entries.
4696 Affected file lib/silcclient/[silcapi.h/idlist.c].
4698 * Removed silc_client_del_client_by_id from silcapi.h.
4700 * Fixed the INFO command to return the server's own info
4701 correctly when querying by Server ID. Affected file is
4704 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4706 * Removed the non-blocking settings in WIN32 code in the
4707 silc_sock_[read/write] and added SleepEx instead. Affected
4708 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4709 of input data is now checked with FIONREAD and ioctlsocket.
4711 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4713 * Call silc_schedule_task_del_by_context in the
4714 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4715 Affected file lib/silccore/silcprotocol.c.
4717 * Call silc_protocol_cancel for active protocols in the
4718 silc_server_close_connection if the funtion
4719 silc_server_free_sock_user_data has not been called.
4720 Affected file silcd/server.c.
4722 * Generic tasks cannot be deleted using the del_by_fd
4723 task deleting function since generic tasks does not match
4724 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4726 * Added a notion to SILCOPER help file that the SILCOPER works
4727 only on router server, not on normal server.
4729 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4731 * Added for WIN32 support for the new scheduler as well.
4732 Affected file lib/silcutil/win32/silcwin32schedule.c.
4734 * Fixed the SHA1 implementation to work on various platforms.
4736 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4738 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4739 API. It is part of the scheduler now. Everything else is
4740 as previously but some functions has changed their names.
4741 Checkout the lib/silcutil/silcschedule.h for the interface.
4742 Updated all applications to use the new interface. Affected
4743 files are lib/silcutil/silcschedule.[ch].
4745 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4747 * Found a bug in the SKE implementation. The HASH value,
4748 specified by the protocol, was not computed correctly. The
4749 public key of the responder was not added to the computation
4750 even though it is mandatory. Affected file lib/silcske/silcske.c.
4751 This unfortunately causes incompatibilities with older
4752 clients and servers.
4754 * Added WIN32 specific network init and uninit functions:
4755 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4756 the Winsock2. Affected file lib/silcutil/silcnet.h and
4757 lib/silcutil/win32/silcwin32net.c.
4759 * Set the socket always to nonblocking mode on WIN32 after
4760 reading data or writing data. Affected file is
4761 lib/silcutil/win32/silcwin32sockconn.c.
4763 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4765 * Fixed various compilation problems under WIN32. Affected
4766 files lib/silcutil/win32/silcwin32thread.c and
4767 lib/silcutil/win32/silcwin32schedule.c.
4769 * Removed all _internal.h #includes from public header
4770 files. Internal headers must never be included from
4773 Removed also the lib/silcske/payload_internal.h file.
4775 * All include files that may be needed (public and some others
4776 included by the public headers) by application developers are
4777 now copied to the ./includes directory. It does not copy any
4778 internal headers. Affected file Makefile.defines.pre and all
4779 Makefile.am's under lib/ and subdirs.
4781 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4783 * Do not change the ~/.silc directory's permissions automatically.
4784 Affected file irssi/src/silc/core/clientutil.c.
4786 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4788 * Do not cancel the protocol in silc_server_close_connection
4789 it might cause recursion. Now cancelled in the function
4790 silc_server_free_sock_user_data. Affected file silcd/server.c.
4792 * Fixed the silc_server_remove_clients_by_server to regenerate
4793 the channel keys correctly finally. Added also new function
4794 silc_server_remove_clients_channels to actually do it.
4795 Affected file silcd/server.c.
4797 * Fixed the silc_server_new_channel to not crash by giving
4798 wrong router to the new channel. Affected file is
4799 silcd/packet_receive.c.
4801 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4803 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4804 which is given as argument to the silc_client_alloc now.
4805 It can be used to configure the client and set various parameters
4806 that affect the function of the client.
4808 * The USERS command in server did not check whether the channel
4809 is private or secret. Affected file silcd/command.c.
4811 * Added new argument to the USERS command in protocol specification.
4812 The USERS command now can take the channel name as argument
4813 as well. Added support for this in client and server and
4814 updated the protocol specs.
4816 * Completed the GETKEY command in client. It can be now used
4817 to fetch also servers public key not only some clients.
4818 Affected files lib/silcclient/command[_reply].c.
4820 * Added silc_client_get_server to return server entry by the
4821 server name. Affected files lib/silcclient/silcapi.h and
4824 * Redefined the IDENTIFY command in protocol specification to be
4825 more generic. It now can be used to query information about
4826 any entity in the SILC Network, including clients, servers and
4827 channels. The query may be based either the entity's name
4828 or the ID. Added support for this in both client and server.
4830 Affected files silcd/command.c and lib/silcclient/command.c
4831 and command_reply.c.
4833 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4834 the _from_client and _from_server functions. Affected file
4837 * Added silc_client_get_channel_by_id_resolve to the file
4838 lib/silcclient/silcapi.h to resolve channel information by
4839 its ID. Added also silc_client_get_channel_by_id that
4840 does not resolve it from the server.
4842 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4844 * Added SilcServerEntry context into the client library
4845 to represent one server. The INFO command now allocates
4846 these to save the resolved server info. For now on the
4847 client library will also keep information about servers,
4848 connected and resolved with INFO.
4850 The INFO command now allocates the SilcServerEntry context
4851 and saves the server info there. The COMMAND_REPLY in
4852 the INFO now returns the parameters to application in
4853 same order as defined in the protocol specification.
4855 The entries are cached in the client->server_cache.
4857 * The INFO command is now issued after received the Client ID
4858 from the server. Affected file lib/silcclient/client.c.
4860 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4861 to the application as the mode changer might be server.
4862 It is guaranteed that NULL is not returned anymore to the
4863 application. Affected file lib/silcclient/client_notify.c.
4865 The ID Type is now also passed to the application so that
4866 it can check whether the returned entry is SilcClientEntry
4869 Added new function silc_client_get_server_by_id to return
4870 the server entry by ID. Affected files are the
4871 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4873 * Do not create the channel in the Irssi SILC Client when issuing
4874 the JOIN command but when received the sucessful JOIN command
4875 reply. Otherwise the channel might get created even though we
4876 could not join it. The Affected file is
4877 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4879 * Fixed a channel joining bug in router. The router must also
4880 check the channel modes, invite and ban lists etc. when serving
4881 the JOIN command sent by normal server. Affected file is
4882 silcd/command.c. The router now resolves the client's
4883 information from the server who sent the JOIN command if it
4884 does not know it, and processes the JOIN command only after
4887 * Changed the SilcCommandCb to take new argument; void *context2.
4888 Affected file lib/silccore/silccommand.h
4890 The second argument in the command callbacks in the server now
4891 includes the SilcServerCommandReplyContext if the command was
4892 called as pending command callback from the command reply.
4893 Otherwise it is NULL. When called as pending the status of the
4894 command reply will be checked and if it was erronous the
4895 error will be sent to the original sender of the command.
4896 This way the client always receives the error messages even
4897 though the server was actually the one who received the error
4898 when it resent the command to router, for example. Affected
4899 files silcd/command[_reply].[ch].
4901 * Fixed sending WHOWAS command's error message to client if
4902 the requested client could not be found. It was missing.
4905 * Changed the CMODE and CUMODE commands reply arguments in the
4906 protocol specification. The Channel ID is now sent in both
4907 of the commands to identify the channel. Implemented this
4908 new feature to the client and server. Affected files
4909 lib/silcclient/command_reply.c and silcd/command.c.
4911 * Made better checks for invite and ban lists in the JOIN
4912 command in server. Affected file silcd/command.c.
4914 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4916 * The server now performs the incoming host IP/DNS lookup
4917 using the silc_socket_host_lookup and thus does not block
4918 the server anymore. Affected file silcd/server.c.
4920 * Completed the multi-thread support for SILC Scheduler in
4921 the lib/silcutil/silcschedule.c.
4923 * Fixed the configure.in.pre to detect the pthread correctly
4926 * Fixed a deadlock in silc_task_queue_wakeup in the file
4927 lib/silcutil/silctask.c.
4929 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4931 * Added new function silc_schedule_wakeup that is used in
4932 multi-threaded environment to wakeup the main thread's
4933 schduler. It needs to be used when a thread adds a new task
4934 or removes a task from task queues. After waking up, the
4935 scheduler will detect the task queue changes. If threads
4936 support is not compiled in this function has no effect.
4937 Implemented the wakeup mechanism to both Unix and WIN32
4938 systems. Affected files are lib/silcutil/silcschedule.[ch],
4939 lib/silcutil/unix/silcunixschedule.c and the
4940 lib/silcutil/win32/silcwin32schedule.c.
4942 * Added new function silc_task_queue_wakeup to wakeup the
4943 scheduler by the specified task queue. Affected file
4944 lib/silcutil/silctask.[ch].
4946 * The silc_socket_host_lookup_start now wakes up the scheduler
4947 after adding the timeout task. Affected file is
4948 lib/silcutil/silcsockconn.c.
4950 * The silc_socket_host_lookup is synchronous now if the threads
4951 support is not compiled in. However, the callback is still
4952 called asyncronously through the scheduler, anyway. Affected
4953 file lib/silcutil/silcsockconn.c.
4955 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4957 * Added new function silc_socket_host_lookup to perform
4958 asynchronous IP and FQDN lookups for the socket connection.
4959 Affected files lib/silcutil/silcsockconn.[ch].
4961 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4963 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4964 that may or may not compile the mutex support in.
4966 Changed the silc_mutex_alloc interface. It allocates the
4967 mutex now to the sent pointer and returns TRUE or FALSE.
4969 Affected file lib/silcutil/silcmutex.h.
4971 * Wrote the SILC Task Queue interface to support multi-threads.
4972 Affected file lib/silcutil/silctask.[ch].
4974 * Wrote the SILC Scheduler to support multi-threads. Affected
4975 file lib/silcutil/silcschedule.c.
4977 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4979 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4980 in lib/silcutil/win32/.
4982 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4984 * Defined SILC Mutex API and SILC Thread API and implemented
4985 them for Unix. Affected files are
4986 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4987 lib/silcutil/unix/silcunixmutex.c and
4988 lib/silcutil/unix/silcunixthread.c.
4990 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4992 * Fixed the silc_server_remove_clients_by_server's channel
4993 key re-generation. The hash table handling was incorrect
4994 and would not work with many channels. Affected file is
4997 * Fixed some memory leaks around the server code.
4999 * Rewrote the silc_server_get_users_on_channel to support IPv6
5000 based Client ID's. Affected file silcd/server.c.
5002 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
5003 specification. However, a separate document must be written
5004 to define the detailed signing procedure and the payload
5005 associated with the flag. Defined the flag to the
5006 lib/silccore/silcchannel.h as well.
5008 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5010 * Changed the dynamic tables to static size tables in the
5011 lib/silccrypt/silchmac.c.
5013 * Removed GCC dependencies from the code. A patch by cras.
5015 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5017 * Do not show the error "Error receiving packet bla bla"
5018 in server if it really was not an error (-2 means that reading
5019 is pending). Affected file silcd/server.c.
5021 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5023 * Fixed a possible crash in silc_server_remove_clients_by_server
5024 in silcd/server.c. Fixed there also some memory leaks.
5026 * Fixed the silc_idlist_replace_client_id. It could replace
5027 wrong key in the hash table. Affected file silcd/idlist.c.
5029 * Do not check whether there are global users on the channel
5030 if the channel->global_users is FALSE. Affected functions
5031 silc_server_remove_from_one_channel and
5032 silc_server_remove_from_channels in silcd/server.c. Also,
5033 do not check if the removed client is local as we can be
5034 sure that global client was not removed from the channel
5035 and checking for global users is not needed.
5037 * The silc_server_remove_clients_by_server now re-generates
5038 the channel keys correctly for those channels that had
5039 clients removed from them. Affected file silcd/server.c.
5041 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5043 * Found the reason of random crashes in the server. We weren't
5044 ignoring the SIGPIPE signal (which can be sent in write())
5045 and it crashed the server. Affected file silcd/silcd.c.
5047 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5049 * Assure that sock->user_data is not NULL in the function
5050 silc_server_packet_send in silcd/packet_send.c.
5052 * Disconnect the remote connection if it could not be added
5053 to any ID lists in the server. The affected file is
5056 * Check in silc_server_packet_send[_real/dest] that the
5057 socket is not disconnecting and ignore the data if it is.
5058 Affected file silcd/packet_send.c.
5060 * Define inline to __inline on native WIN32 compilation.
5061 Affected file includes/silcwin32.h.
5063 * Added some explicit type casts for inline code since MSVC
5064 require them. Affected files lib/silcutil/silcbuffer.h,
5065 lib/trq/silcdlist.h and lib/trq/silclist.h.
5067 * Print warning in log files from now on if the packet
5068 decryption fails. Affected file silcd/server.c.
5070 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5072 * Changed the `say' client operation's interface to accept
5073 new `type' argument to indicate the type of the message sent
5074 by the library. The application may filter the library's
5075 messages according the type. The affected file is the
5076 lib/silcclient/silcapi.h.
5078 * Added two new functions to lib/silcclient/silcapi.h:
5079 silc_client_del_client and silc_client_del_client_by_id.
5080 Affected file lib/silcclient/idlist.c.
5082 * Moved the clientincludes.h from includes/ to silc/ and
5083 serverincludes.h from includes/ to silcd/.
5085 * The modes for the CMODE and CUMODE are now passed as
5086 uint32 for application with COMMAND_REPLY. The affected
5087 file is lib/silcclient/command_reply.c.
5089 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5091 * /WHOIS without arguments shows client's own information.
5092 Affected file lib/silcclient/command.c.
5094 * Changed PING to not accept any arguments. The specs
5095 says that client can ping only the connected server so
5096 requiring an argument is not needed. Affected file is
5097 lib/silcclient/command.c.
5099 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5101 * Fixed a fatal bug in private message sending and reception
5102 encryption and decryption when using private message keys.
5103 The implementation was incorrect and did not follow the
5104 specification. It causd that some of the message were
5105 lost since it did not use the sending and receiving keys
5106 as the protocol suggests. This has been fixed and will cause
5107 incompatibilities with older clients when sending private
5108 message encrypted with private message keys. Affected files
5109 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
5110 and various other in Irssi SILC Client.
5112 Added `responder' boolean argument to the functions
5113 silc_client_add_private_message_key[_ske] to indicate when
5114 the key is added as responder or initiator of the key
5117 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5119 * Removed the silc_ske_check_version function and created
5120 a SilcSKECheckVersion callback. Added also a function
5121 silc_ske_set_callbacks that is now used to set all SKE
5122 callbacks. The callback functions are not given to
5123 the SKE functions anymore, but this function is used to
5126 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
5128 * Added `silc_version' argument to the silc_client_alloc
5129 to define the version of the application for the library.
5130 The library will use the version string to compare it
5131 against the remote host's (usually a server) version
5132 string. Affected file lib/silcclient/silcapi.h
5134 * Added the KE protocol context to Key Agreement context
5135 in client library so that we can abort the SKE if it
5136 is in process when we get timeout. Affected file is
5137 lib/silcclient/client_keyagr.c.
5139 * Do not resolve the client ID forever if it returns in the
5140 first time that such client does not exist. This was done
5141 for example with private message. Affected file is
5142 lib/silcclient/client_prvmsg.c.
5144 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5146 * Do not add regex.h for WIN32. The affected file
5147 includes/silcincludes.h.
5149 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
5150 not work yet 100%. It generates the DLL's automatically
5151 when compiling with --with-win32 under cygwin.
5153 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5155 * lib/contrib/regex.c is not compiled on WIN32.
5157 * Added silc_net_get_socket_opt function to the
5158 lib/silcutil/silcnet.h.
5160 * Added includes/silcwin32.h for WIN32 specific includes
5163 * Do not use ptime structure or any of the posix process
5164 functions on WIN32 in lib/silccrypt/silrng.c.
5166 * Added silc_gettimeofday to provide generic function
5167 for struct timeval on all platforms. Added the function
5168 to lib/silcutil/silcutil.h.
5170 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5172 * Moved the lib/silccore/silcsockconn.[ch] to the utility
5173 library as they clearly belong there. As a plus side we
5174 can make the actual socket connection routines platform
5177 Added also new generic function silc_socket_read and
5178 silc_socket_write (that used to be silc_packet_[read/write].
5179 The implementation of these are platform specific.
5181 * Added WIN32 specific routines of silc_socket_[read/write]
5182 to lib/silcutil/win32/silcwin32sockconn.c.
5184 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5186 * Added preliminary support for native WIN32 compilation under
5187 cygwin (using the -mno-cygwin option for GCC) to the
5188 ./configure.in.pre. The --with-win32 now prepares the
5189 compilation for native WIN32.
5191 * Rewrote the SILC Scheduler interface in the file
5192 lib/silcutil/silcschedule.h. The scheduler is now context
5193 based and does not have anymore any global static scheduler.
5194 Moved the Unix scheduler to the lib/silcutil/unix/ directory
5195 and created lib/silcutil/win32 directory for WIN32 based
5198 * Added Unix specific network routines to the
5199 lib/silcutil/unix/silcunixnet.c and the old
5200 lib/silcutil/silcnet.c includes now only generic routines.
5202 Added WIN32 specific network routines to the
5203 lib/silcutil/win32/silcwin32net.c.
5205 * Added Unix specific utility functions from the
5206 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
5208 * Added WIN32 SILC Scheduler to the file
5209 lib/silcutil/win32/silcwin32schedule.c. The code is of course
5212 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
5214 * Do not handle JOIN notify in the server if the target client
5215 is not registered (idata->registered == FALSE). The affected
5216 file is silcd/packet_receive.c.
5218 * Update the nickrec->founder in event_cumode in the Irssi SILC
5219 client. Affected file irssi/src/silc/core/silc-channels.c.
5221 * Fixed the CUMODE_CHANGE notify handling in the server when
5222 server and router are announcing their clients on channels.
5223 Now the mode changes are saved and notified correctly. The
5224 affected file is /silcd/packet_receive.c.
5226 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
5227 They really did not replace the cache entry in the ID Cache.
5228 Now they do that. Affected file silcd/idlist.c.
5230 * Fixed the KICK notify handling in the Irssi SILC client to
5231 update the channel records so that the kicked client does not
5232 appear to be on the channel. The affected file is
5233 irssi/src/silc/core/silc-channels.c.
5235 * Always update the conn->current_channel when executing command
5236 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
5238 * Fixed the KILL notify handling in Irssi SILC client to remove
5239 the killed client on all channels.
5241 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * Fixed the silc_parse_command_line to remove extra spaces
5244 from the start and end of the arguments. Affected file is
5245 lib/silcutil/silcutil.c.
5247 * Cancel and free any active protocol in the function
5248 silc_server_close_connection. Affected file silcd/server.c.
5250 * Cancel and free any active protocol in the function
5251 silc_client_close_connction. Affected file is
5252 lib/silcclient/client.c.
5254 * Do not execute the KILL command for clients that are in
5255 history (ie. they are not in the network). Affected file is
5258 * Fixed KILL notify handling, client does not crash anymore.
5259 Affected file irssi/src/silc/core/silc-channels.c.
5261 * Reduced the default packet buffer size from 2048 to 1024 in
5262 lib/silccore/silcpacket.c.
5264 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
5265 counter to the SKE context that is incresed when the SKE library
5266 performs async operation outside the library. If the outside
5267 process frees the SKE context and FREED status will be set
5268 and the library will detect after the sync operation that the
5269 libary is freed. The affected files are
5270 lib/silcske/silcske[_status].[ch].
5272 * Resolve the client entry information in the function
5273 silc_client_channel_message to assure that NULL pointer is not
5274 passed as client entry to the application. */
5276 * Fixed the task timeout calculation to assure that there is
5277 never negative timeouts. The affected file is
5278 lib/silcutil/silcschedule.c.
5280 * Fixed the channel user mode notification sending in server.
5281 It was sent point-to-point to the router (or to server by router)
5282 but it needs to be destined to a channel. The routines now
5283 supports sending the channel user mode notifys to the channels
5284 when announcing clients and channels. Affected files are
5285 silcd/server.c and silcd/packet_receive.c.
5287 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5288 It did not actually replace the old channel entry in the cache.
5289 Affected file lib/silcclient/client_notify.c.
5291 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5293 * Fixed a possible crash in silc_packet_send_prepare. It now
5294 assures always that there is enough space in the buffer and
5295 at the tail area of the buffer (for MAC).
5297 Fixed the inbound buffer reallocation in silc_packet_read.
5298 It was old code and did not handle the reallocation correctly.
5301 The affected file is lib/silccore/silcpacket.c.
5303 * Fixed buffer overflow in silc_parse_nickname in the file
5304 lib/silcutil/silcutil.c.
5306 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5308 * make install generates new server keys only if there is not
5311 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5313 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5314 Added check that if the NOREPLY is set then we will not send
5315 the away message. This avoids infinite loop of away messages
5316 if both clients are away. The affected file is
5317 lib/silcclient/client_prvmsg.c.
5319 * Fixed client crash if /NICK was given without arguments.
5320 Affected file lib/silcclient/command.c.
5322 * Server does not send the invite list in INVITE command back
5323 to the client if the list was not altered. Added this notion
5324 to the protocol spec as well. Affected file silcd/command.c.
5326 Fixed possible crash in INVITE command by checking the
5327 value of silc_server_get_client_route command.
5329 * Fixed the INVITE notify type handling. The arguments are now
5330 taken in correct order and client does not crash. The affected
5331 file is irssi/src/silc/core/silc-channels.c.
5333 Removed the "Inviting xxx to channel" message from the
5334 client library away and let the application handle it.
5335 Affected file lib/silcclient/command.c. Added that message
5336 to Irssi SILC client's message formats.
5338 * Fixed CMODE command crash in client. It now checks the
5339 amount of arguments correctly and does not crash. The affected
5340 file is lib/silcclient/command.c.
5342 * Do not create new channel automatically in silc_channels_join
5343 but check whether the channel by that name already exists.
5344 Affected file irssi/silc/core/silc-channels.c.
5346 * Do not send the SERVER_SIGNOFF to router if the disconnected
5347 entity was the router. Affected file silcd/server.c.
5349 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5350 SILC client as it was missing from there.
5352 Added the handling of the KICK notify to the Irssi SILC client
5353 as it was missing. Added "you have been kicked" message to
5354 Irssi SILC client's message modules formats.
5356 Added the handing of the KILL notify to the Irssi SILC client
5357 as it was missing. Added the kill message module formats
5360 The affected file is irssi/src/silc/core/silc-channels.c.
5362 * The router did not save the channel mode the server announced.
5363 Affected file silcd/packet_receive.c.
5365 * Fixed a possible crash in INFO command in server. If the
5366 server did not provide the server info it crashed. Affected
5367 file silcd/command.c.
5369 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5371 * Fixed the GETKEY command in the server to check also the
5372 global list. Otherwise the GETKEY would not work correctly
5373 in normal SILC server. Affected file silcd/command.c.
5375 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5377 * Fixed GETKEY crash, it crashed if the command did not succseed.
5379 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5381 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5382 is now real and not just an macro interface to GMP.
5384 Removed the entire GMP from the source tree and imported new
5385 NSS MPI library instead. Reason for removing GMP is that it is
5386 extremely large and compiles extremely slow. The NSS MPI
5387 is only a few files and compiles in less than 10 seconds.
5388 The speed is also about the same as GMP. The MPI is imported
5389 to lib/silcmath/mpi.
5391 If the system has GMP installed we will still use the GMP.
5392 If it is not then the NSS MPI will be compiled.
5394 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5396 * Merged a long nickname (127 characters long) crash bugfix from
5397 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5399 * Merged a freed memory reference bugfix from Irssi CVS tree.
5400 Affected file irssi/src/core/commands.c.
5402 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5404 * Added the server's public key sving and verification to the
5405 server when performing the SKE. This was missing and the
5406 remote server's (or router's) public key was accepted without
5407 checking whether we have it previously or trust it at all.
5408 Affected file silcd/protocol.c.
5410 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * Check in the silc_server_timeout_remote if protocol is active
5413 and make sure that the protocol's final callback is called so
5414 that all memory if freed. Affected file silcd/server.c.
5416 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5418 * silc_server_whois_send_reply crashed the server if the nickname
5419 was 127 characters long. Affected file silcd/command.c.
5421 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5423 * Added sanity check to the silc_server_new_client. If the hostname
5424 is provided inside username then check that the provided hostname
5425 really is the same as the resolved one. If the hostname was not
5426 resolved then check it from the public key. Affected file is
5427 silcd/packet_receive.c.
5429 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5430 if the server disconnected us and the connection is not valid
5431 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5433 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5434 the library to the lib/silcutil/silcutil.[ch].
5436 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5438 * Close log file after open. Affected file
5439 lib/silcutil/silclog.c.
5441 * Check whether sock == NULL in silc_client_send_packet and return
5442 if it is. Affected file lib/silcclient/silcclient.c.
5444 * Check rec->entry == NULL in the Irssi SILC Client before
5445 sending the channel message. Affecte file is
5446 irssi/src/silc/core/silc-servers.c.
5448 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5450 * Merged a splitted window bugfix from Irssi CVS tree. The
5451 affected file is irssi/src/fe-text/textbuffer-view.c.
5453 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5454 It did not print nickname.
5456 * Improved the distributions system a bit.
5458 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5460 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5461 irssi/src/fe-text/gui-window.c.
5463 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5464 to in-active server. The affected file is
5465 irssi/src/silc/core/client_ops.c.
5467 * Resolve the client in USERS command reply if the entry does
5468 not have username resolved. The affected file is
5469 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5470 command to WHOIS command to really resolve stuff. The USERS
5471 is not used any more in any critical section so WHOIS can
5472 be used even though it might be slower than IDENTIFY.
5474 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5477 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5479 * Changed the protocol API a bit more consistent in the
5480 lib/silccore/silcprotocol.[ch].
5482 * Changed the following headers to ROBODoc format:
5484 lib/silccore/silcpayload.h
5485 lib/silccore/silcprotocol.h
5486 lib/silccore/silcsockconn.h
5488 All core library headers are now formatted.
5490 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5492 * Fixed a bug in Irssi SILC client; do not show that you are
5493 server/router operator if you really are not. Affected file is
5494 irssi/src/silc/core/client_ops.c.
5496 * Renamed silc_command_free_payload to silc_command_payload_free.
5497 Affected file lib/silccore/silccommand.h
5499 * Added silcmath.h to include the prototoypes of various routines
5500 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5503 * Changed the following headers to ROBODoc format:
5505 lib/silccore/silcchannel.h
5506 lib/silccore/silccommand.h
5507 lib/silccore/silcid.h
5508 lib/silccore/silcidcache.h
5509 lib/silccore/silcmode.h
5510 lib/silccore/silcnotify.h
5511 lib/silccore/silcpacket.h
5512 lib/silcmath/silcmath.h
5514 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5516 * Added checking to the server code not to start the server if
5517 ciphers and stuff are not configured properly. Affected files
5518 silcd/serverconfig.[h] and silcd/server.c.
5520 * Changed the layout of the header files of the public interfaces
5521 in the SILC libraries. The new layout supports ROBODoc
5522 documentation tool (and some others) so that it is easy to create
5523 a library reference manual. All the other headers and source
5524 code must still follow the CodingStyle document. Also source
5525 code must not include these ROBODoc stuffs, only the headers.
5526 Furthermore, all public interface headers must now be named
5527 by using `silc' prefix, example: silcapi.h, silccipher.h.
5528 Some files were renamed due to this. All the other headers
5529 must not be used as public interfaces. I will update the
5530 CodingStyle document later. Changed following headers, so far:
5532 lib/silcclient/silcapi.h
5533 lib/silccore/silcauth.h
5534 lib/silccore/silcprivate.h
5535 lib/silccrypt/silcdh.h
5537 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5541 * Removed silc_client_packet_send_flush from the client library
5542 as it is not needed. Affected file lib/silcclient/client.[ch].
5544 * Added printing of message of unresolved authentication method
5545 to the Irssi SILC client. Added it to the module formats.
5546 Removed the same message from the client library.
5548 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5550 * Added new distribution feature, DISTLABEL. Every distribution
5551 can define own preprocessor label that can be used in the
5552 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5553 file distributions, acconfig.h.pre and prepare.
5555 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5557 * Added Makefile.defines_int to include the actual definitions
5558 for Makefile.defines.in. Tested the new distribution system,
5559 created distributions and tested installation.
5561 * Added AWAY message printing to the Irssi SILC client. Added
5562 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5564 * Added SCONNECT command to call the SILC's CONNECT command.
5565 Cannot use CONNECT directly since Irssi uses that internally.
5566 Affected file irssi/src/silc/core/silc-servers.c.
5568 Added ACTION local command. It is same as ME command but takes
5569 the channel as mandatory argument.
5571 Rewrote some of the Irssi's help files to suite for SILC
5574 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5576 * Added Makefile.defines[.in] that should for now on be included
5577 in all Makefile.am file in the source tree. That file includes
5578 all common compilation definitions for SILC source tree.
5580 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5582 * Minor changes to the ./prepare script to change the package
5583 name according the distribution name to the configure.in.
5585 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5587 * Created new distribution system. Added file `distributions'
5588 that defines all the distributions that can be created out of
5589 the SILC source tree. The ./prepare script now reads that
5590 file to determine how to prepare the distributions. The
5591 first argument to the ./prepare is the name of the distribution
5592 and second is the version of the distribution. If given
5593 without arguments it creates the default (toolkit) distribution
5594 with the default version (defined in ./prepare).
5596 All Makefile.am files that are subject to the distributions
5597 are now named as Makefile.am.pre. These are ./Makefile.am
5598 and lib/Makefile.am. Others may be changed later.
5600 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5602 * Added invite list, ban list, some key management and connection
5603 error message printing to module formats in the Irssi SILC client.
5605 * Added new silc_client_set_away_message to set the away message
5606 that is back to the person who sent private message. The
5607 affected file lib/silcclient/silcapi.h and the
5608 lib/silcclient/client_prvmsg.c.
5610 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5612 * Fixed the private message sending in the Irssi SILC client,
5613 added local command KEY to the Irssi SILC client.
5615 Added key management and key agreement message formats to the
5616 irssi/src/fe-common/silc/module-formats.[ch].
5618 Added USERS (alias WHO) printing, server/router operator
5619 indication and LIST command printing to the module formats.
5621 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5623 * Fixed channel joining notify handling, cumode notify handling
5624 from Irssi SILC client.
5626 * Added SILC specific module-formats to the Irssi SILC client so
5627 that SILC specific message hilighting, colors etc is possible.
5628 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5630 Added channel mode, channel user mode, actions, notices,
5631 whois and whowas printing to the the module-formats.c.
5633 * Fixed a bug in channel deletion in the server. The channel
5634 is not left to the cache even if the channel founder auth mode
5635 is set when there are no users anymore on the channel. Affected
5636 file silcd/server.c.
5638 * The silc_net_localhost now resolves the entire hostname including
5639 the domain name. Affected file lib/silcutil/silcnet.c.
5641 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5643 * Changed the ask_passphrase client operation to be ascynchronous.
5644 It has now a completion callback and a context that the
5645 application must call after it has got the passphrase from
5646 the user. Affected files lib/silcclient/silcapi.h,
5647 lib/silcclient/protocol.c, lib/silcclient/command.c and
5650 Added SilcAskPassphrase callback that the application calls
5651 to deliver the passphrase to the library.
5653 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5654 The public key verification and especially a certificate
5655 verification is asynchronous procedure.
5657 Added new SILC_SKE_STATUS_PENDING status to indicate the
5658 request is pending and a callback will be called to finalize
5661 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5662 indicate that remote end did not send its public key (or
5663 certificate), even though we require it. Added check for this
5664 condition in the SKE. This was a security bug, now fixed.
5666 Defined new SilcSKEVerifyCbCompletion callback that is called
5667 when the verification process is completed.
5669 The affected files lib/silcske/silcske_status.h and
5670 lib/silcske/silcske.[ch].
5672 * Changed the verify_public_key client operation to be async
5673 as well. Defined SilcVerifyPublicKey callback that is used to
5674 indicate the success of the public key verification process.
5676 Changed the server and client to use the new async client
5679 * Changed the Irssi SILC client's internal scheduler to be called
5680 twice as many times as it used to be. As a result the client
5681 should be a bit faster now. Affected file is
5682 irssi/src/silc/core/silc-core.c.
5684 * Added support to Irssi SILC client of asynchronous public key
5685 verification and passphrase inquiry. Affected file is
5686 irssi/src/silc/core/silc-core.c.
5688 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5690 * Do not say "You have left channel %s" in client library.
5691 Moved it to the application. Affected files are
5692 lib/silcclient/command.c and silc/client_ops.c.
5694 * Fixed silc_client_get_clients. Command context was not
5695 duplicated and was freed memory in the callback. Affected
5696 file lib/silcclient/idlist.c.
5698 * Do not say "you are now talking..." on JOIN command in the
5699 client library. The appliation must handle it.
5701 * Do not say ".. changed topic to" in command reply in the
5702 client libary. The application must handle it.
5704 * Fixed TOPIC command sending in the client library.
5706 * Fixed a memory leak in silc_client_command_free in the file
5707 lib/silcclient/command.c.
5709 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5711 * Imported a modified version of Irssi client to the source tree.
5712 The Irssi will be used to create a new client called
5713 Irssi SILC. Imported to irssi/.
5715 Added silc_core_init_finish function to the Irssi. Affected
5716 file irssi/configure.in.
5718 A lot changes in the Makefile.ams around the irssi tree.
5720 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5722 * Do not rehash if the new size is same as the old size of the
5723 hash table, in the silc_hash_table_rehash*. The affected file
5724 lib/silcutil/silchashtable.c.
5726 * Replaced hash_table_del_by_context calls from the server
5727 (when channel->user_list and client->channels) to the
5728 hash_table_del as it is sufficient and faster.
5730 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5732 * Added silc_hash_table_list, silc_hash_table_get and the
5733 SilcHashTableList structure to provide an alternative way to
5734 traverse the hash table. The affected files are
5735 lib/silcutil/silchashtable.[ch].
5737 * Changed the server's idlist routines to use the hash table
5738 routines to optimize the code.
5740 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5742 * Replaced the client entry's `channel' list and channel entry's
5743 `user_list' list to hash tables for optimized lookup. Changed
5744 the code to use the hash table interface around the code.
5745 Affected file lib/silcd/idlist.[ch].
5747 * Added `auto_rehash' boolean argument to the function
5748 silc_hash_table_alloc to indicate whether the hash table should
5749 auto-rehash when it thinks is appropriate time. It will
5750 increase the hash table size if the there is twice as much
5751 entries in the table than the size of the table, and will
5752 decrease the size if there are twice as less entries than
5753 the size of the table.
5755 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5757 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5759 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5761 * silc_idcache_purge_by_context deletes the entry now by context
5762 as it is supposed to do. Affected file lib/silccore/idcache.c.
5764 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5765 client is not anymore valid (WHOWAS givens the info) and not
5766 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5768 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5770 * Removed the `data' and `data_len' arguments from the ID Cache
5771 interfaces and added `name' argument. ID Cache does not handle
5772 anymore the binary data only a names associated with given ID.
5774 * When hashing a Client ID with silc_hash_id the entire ID is
5775 not hashed anymore, instead only the hash of the Client ID is
5776 hashed. This way we can access the Client ID from the cache
5777 with Client ID but with the hash of the ID (which is a hash of
5778 the nickname) as well without any difference in performance.
5780 Added also silc_idcache_find_by_id_one_ext to do one on one
5781 searching when we have the actual ID. Added also function
5782 silc_hash_client_id_compare. The affected files are
5783 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5785 * When hashing the name associated with a ID it is always done
5786 in lowercase. This way we can access the cache without worrying
5787 about case-sensitivity, even though, for example nicknames are
5790 * Fixed a bug in server with channel message sending. It put
5791 wrong ID type as destination ID. The affected file
5792 silcd/packet_send.c.
5794 * silc_idcache_del_by_context now deletes from all hash tables
5795 by context. Affected file lib/silccore/idcache.c.
5797 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5799 * Changed the client library to use the new ID Cache interface.
5800 Changes around the source tree.
5802 * Added silc_hash_table_rehash_ext to rehash with specific
5803 hash function. Affected file lib/silcutil/silchashtable.[ch].
5805 * Added silc_hash_string_compare to compare two strings in the
5806 hash table. Affected file lib/silcutil/silcutil.[ch].
5808 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5810 * Added new function silc_idcache_del_by_context into the
5811 lib/silccore/idcache.[ch].
5813 * Changed the server's ID list routines to use the new ID Cache
5814 interface. Changes around the source tree.
5816 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5818 * Added silc_hash_table_del[_by_context]_ext functions in to the
5819 lib/silcutil/silchashtable.[ch].
5821 Removed silc_hash_table_find_all* routines and added new
5822 silc_hash_table_find_foreach to replace them.
5824 Added silc_hash_table_replace_ext function as extended
5825 replacing function. Separated the simple hash table interface
5826 from the extended hash table interface in the file
5827 lib/silcutil/silchashtable.h.
5829 * Fixed minor bugs and changed it to use some of the new
5830 hash table functions in lib/silccore/idcache.c
5832 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5834 * Added new function silc_hash_table_find_all to return all keys
5835 in the hash table by the specified key. As the hash table is
5836 collision resistant it also makes it possible to have several
5837 duplicate keys in the hash table. This function may be used to
5838 find all of the keys from the hash.
5840 Added user_context arguments to the SilcHashFunction,
5841 SilcHashCompare and SilcHashDestructor to deliver user specified
5844 Added new fuctions silc_hash_table_find[_all]_ext to do
5845 extended lookup with specified hash and compare functions and
5846 specified user contexts.
5848 Added new function silc_hash_table_add_ext to add the key
5849 with specified hash function and user context.
5851 Added new function silc_hash_table_foreach to traverse all
5852 entrys in the hash table. Added SilcHashForeach callback
5855 Added new function silc_hash_table_del_by_context to delete
5856 the entry only if the context associated with the key matches.
5858 Affected files are lib/silcutil/silchashtable.[ch].
5860 * Removed silc_hash_[server/client/channel]_id and added just
5861 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5862 silc_hash_id_compare to compare two ID's using as the hash table
5863 comparison function. Added also silc_hash_data to hash
5864 binary data and silc_hash_data_compare to compare it.
5866 * Removed silc_idlist_find_client_by_hash as it is not needed
5867 anymore. Affected file silcd/idlist.[ch].
5869 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5870 to use internally the SilcHashTable. The new ID Cache is a lot
5871 faster than the old one. Some of the ID Cache interface was also
5872 rewritten and obsolete and stupid functions were removed.
5874 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5876 * Added entry_count field to the SilcHashTable to keep the number
5877 of the entries in the table. Implemented the function
5878 silc_hash_table_rehash. Added new function
5879 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5881 Fixed a minor bug in silc_hash_table_free.
5883 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5884 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5885 into the lib/silcutil/silcutil.[ch].
5887 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5889 * Implemented a collision resistant hash table into the
5890 lib/silcutil/silchashtable[ch]. See the header and the source
5891 for the SilcHashTable API.
5893 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5895 * Merged dotconf version 1.0.2 into lib/dotconf.
5897 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5899 * Do not compile anything in lib/silcsim/* if the SIM support
5900 is not enabled. The tree should now compile without problems
5903 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5905 * Compiled the SILC under cygwin. Compiled and tested briefly
5906 without problems. More tests needed. The SIMs didn't compile
5909 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5911 * Fixed possible crash in silc_get_username in the
5912 lib/silcutil/silcutil.c.
5914 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5916 * Fixed a va_arg in silc/client_ops.c.
5918 * Oops, RC5 routines were named AES and caused some problems
5919 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5921 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5923 * Added new SilcIDIP structure into the lib/silccore/id.h and
5924 replaced the old `ip' fields from all SILC ID's to that type.
5925 This is a step towards IPv6 support.
5927 The silc_id_get_len takes now the ID as an extra argument.
5928 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5929 both IPv4 and IPv6 based ID's.
5931 The affected files are lib/silccore/id.[ch] and other files
5932 around the tree using these routines.
5934 * Removed the ID length arguments in server from various
5935 silc_server_send_notify_* routines -> they are not needed
5938 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Fixed memory leak in silc_encode_pem_file in the file
5941 lib/silcutil/silcutil.c.
5943 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5945 * Check minor version as well in the SKE. Affected files are
5946 silcd/protocol.c and lib/silcclient/protocol.c.
5948 * Added --identifier option to the server so that an identifier
5949 can be when creating the public key for the server. Affected
5950 file is silcd/silcd.c.
5952 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5953 lib/silccrypt/silcpkcs.c.
5955 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5957 * Register default ciphers and stuff when using -C option with
5958 the server. Affected file sildc/silcd.c.
5960 * Put back the servers public key filename format, it is better
5961 than the new one. For now, the client keys are saved with the
5962 new filename format. The affected file silc/client_ops.c.
5964 * Implemented the Cipher API for the rest of the ciphers that
5965 did not implement it or implemented it the wrong way.
5967 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5969 * Register default ciphers and stuff when using the -S option
5970 in the client. Affected file silc/silc.c. Same also when
5971 creating new key pair with -C option.
5973 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5975 * Fixed the silc_verify_public_key client operation function to
5976 save the public keys differently. The fingerprint is now
5977 used as filename and not the hostname. This way also the
5978 client keys are saved uniquely and not with hostnames. The
5979 affected file is silc/client_ops.c.
5981 * Trimmed the silc_hash_fingerprint function to remove extra
5982 whitespaces from the end of the fingerprint. The affected
5983 file is lib/silccrypt/silchash.c.
5987 * Added silc_cipher_register_default function to register all
5988 default ciphers. It can be used when configuration files
5989 does not exist and the application does not want any specific
5990 ciphers in any specific order.
5992 The SilcDList is now used as silc_cipher_list dynamically
5993 allocated cipher list. Removed the static list all together
5994 and now all ciphers must be allocated to the dynamic list.
5995 The silc_cipher_alloc routine was changed to check only the
5998 All silc_cipher_* routines that used to return int returns
6001 The affected files lib/silccrypt/silccrypt.[ch].
6003 * The same thing was done to silc_hash_* as for silc_cipher_*
6004 routines. Affected files lib/silccrypt/silchash.[ch].
6006 * The same thing was done to silc_pkcs_* as for silc_cipher_*
6007 routines. Affected files lib/silccrypt/silcpkcs.[ch].
6008 Added also silc_pkcs_[un]register[_default] functions.
6009 Removed the data_context from the PKCS API.
6011 * Added silc_hmac_register_default function to register default
6012 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
6013 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
6014 to unregister all hmacs at once.
6016 * Register the default ciphers, hash functions, PKCSs and HMACs
6017 if client's configuration file does not exist. The affected
6020 * The client did not load the hash functions from the SIM
6021 modules at all. Added support for this. Affected file is
6022 silc/clientconfig.c.
6024 * When decoding public key with silc_pkcs_public_key_decode, check
6025 the supported algorithm only if PKCS are registered. Affected
6026 file lib/silccrypt/silcpkcs.c. The same was done with the
6027 silc_pkcs_private_key_decode.
6029 * Fixed the SILC List routines to keep the list always in order.
6030 It used to change the list's order when traversing the list but
6031 not it preserves the order. Affected file lib/trq/silclist.h.
6033 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6035 * Added the client library to use the SilcSocketConnection's
6036 reference counter (by silc_socket_dup) to prevent the bug that
6037 the socket object may be freed underneath async operation.
6039 * The name resolv library checking fixes in the configure.in.pre.
6042 * Created new version of the protocol drafts for future
6043 development. The -03 drafts are the ones that will be changed
6044 in the trunk now and the -02 will remain as they are.
6046 * Send list of CUMODE notifys to the router when announcing
6047 the channel users to the router. Affected file silcd/server.c.
6048 If the router receiving channel founder CUMODE for a channel
6049 that already has channel founder it will send CUMODE notify
6050 to the sender to remove the channel founder rights from the
6051 announced client. Affected file silcd/packet_receive.c.
6053 * The CUMODE notify may now use Server ID as well as the entity
6054 who changes the mode. Updated protocool specs.
6056 * Updated INSTALL and README files.
6058 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6060 * New web pages in the http://silc.pspt.fi. The pages was
6065 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6067 * Implemented the [DenyConnectin] config section in the server.
6068 Added silc_server_config_denied_conn to check whether incoming
6069 connection is denied. Affected file silcd/serverconfig.[ch].
6071 * Do not check the ports when checking the incoming configuration
6072 data if the port is 0, meaning any. Affected file is
6073 silcd/serverconfig.c.
6075 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6077 * Fixed buffer overflow in silc_string_compare in the file
6078 lib/silcutil/silcutil.c.
6080 * Fixed double free in silc_server_command_leave in the file
6083 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6085 * Fixed the version checking in the server. Affected file is
6088 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6090 * Fixed the configuration data fetching when accepting new
6091 connections in the server. Affected file silcd/server.c.
6093 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6095 * Added `sender_entry' argument to the function
6096 silc_server_packet_relay_to_channel so that we can check
6097 whether some destination actually belongs to the same route
6098 the sender belongs (ie, we must not resend the packet to the
6099 sender). Affected file silcd/packet_send.[ch].
6101 * Added `servername' field to the SilcClientEntry in the server
6102 to hold the name of the server where client is from. Affected
6103 file is silcd/idlist.h.
6105 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * Moved the channel message encrypting in the router betwen
6108 router connections from silc_server_channel_message to the
6109 silc_server_packet_relay_to_channel since we want to check
6110 whether we have anybody channel before encrypting anything.
6111 Affected files silcd/packet_[receive/send].c.
6113 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6115 * Fixed the [AdminConnection] server config section to support
6116 multiple entries. Affected file silcd/serverconfig.c.
6118 * Added support into the server to check the validity of the
6119 incoming connection before executing any KE or authentication
6122 * The connection configuration is now saved to the KE and
6123 connection auth protocol contexts and not fetched anymore in
6124 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
6126 * The local hosts listenning address and port is also resolved
6127 now when starting the server. We want to have the socket object
6128 to include the real address and port for the listener. Added
6129 new function silc_net_check_local_by_sock into the files
6130 lib/silcutil/silcnet.[ch].
6132 * Fixed a broadcast bug in server -> do not broadcast if we
6135 * Fixed a routing bug. Do not route broadcast packets ever.
6136 Broadcast packets must be processed always and not routed since
6137 they may be destined to some other host than yourself and thus
6138 would get routed without no good reason. Affected file is
6141 * Added function silc_server_config_is_primary_route to check
6142 whether primary router connection has been configured (a router
6143 configuration that we are initiating). If there is not, we
6144 will assume that there is only two routers in the SILC network
6145 and we will use the incoming router connection as our primary
6146 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
6148 * Changed the order of the broadcasting. Broadcast _after_ the
6149 packet has been processed not before. Affected file is
6152 * Fixed a [ClientConnection] parsing bug. The port was never
6153 parsed correctly thus resulting to port 0. Affected file
6154 silcd/serverconfig.c.
6156 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
6157 argument and did not set the broadcast packet flag. Affected
6158 file silcd/packet_send.c. Fixed same bug in the function
6159 silc_server_send_notify as well.
6161 * If we receive NEW_ID packet for our own ID in the server, ignore
6164 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6168 * Removed the nickname from the Private Message Payload.
6169 Updated the code and the protocol specs.
6171 * Updated protocol specs for submitting to the IETF.
6173 * Tweaked the Random Number Generator a bit. Affected file
6174 lib/silccrypt/silcrng.c. Exported a new function
6175 silc_rng_[global]_add_noise which can be used to add more
6178 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6180 * Do not parse packets with different timeout when protocol
6181 is active -> may cause problem with rekey. Affected file
6184 * When server receives signoff notify it must not create
6185 new channel key if the client is on any channels since the
6186 sender of the signoff notify will create it.
6188 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6190 * Added printing of error messages during SKE protocol from the
6191 failure packet sent by server during SKE. Affected file
6194 * Removed the client's failure_callback handling with timeout
6195 and handle it immediately when received.
6197 * The SKE library returned wrong type in SUCCESS and FAILURE
6198 packets. They must be 32 bit MSB not 16 bit MSB.
6200 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6202 * Ok, rewrote the logic of the re-key and now it seems to work.
6203 I tested it on high traffic with frequent re-keys without
6204 problems. Added hmac_receive (and renamed hmac to hmac_send)
6205 in SilcClientConnection in lib/silcclient/client.h and
6206 in SilcIDListData in silcd/idlist.h. Also, removed the
6207 SilcPacketParserContext's cipher and hmac fields as they are
6208 not needed anymore and actually caused some problems when
6209 the ciphers and hmac's changed underneath the packet parser.
6211 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6213 * If re-key protocol is active then process the incoming packets
6214 synchronously since we must assure that icoming packets encrypted
6215 with the old key is processed before the new keys is set to
6216 use. This is true other packets than for REKEY packets.
6217 Affected file silcd/server.c. The same was done to client library
6218 as well, affected file lib/silcclient/client.c.
6220 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6222 * Fixed bug in client and server to accept the force send if
6223 the packet is send from silc_[server/client]_packet_process
6224 function. Otherwise the packets are never delivered, oops.
6226 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6228 * Disable force sending of packets when REKEY protocol is active.
6229 We must assure that no packet is sent directly when rekey is
6230 performed. All packets must be sent through packet queue.
6231 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
6232 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
6233 function is silc_[server/client]_packet_send_real to check
6236 * Replaced the SIM paths from example config files to
6237 /usr/local/modules. Also, make install creates now
6238 /usr/local/silc/logs directory to hold all the SILC server
6241 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6243 * Made the configure.in.pre work on Solaris. Patch by salo.
6245 * Made all ciphers compatible with non-x86 machines. Defined
6246 CBC mode macros into lib/silccrypt/ciphers_def.h.
6248 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6250 * Fixed the make install.
6252 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6254 * When MAC computation fails the silc_packet_decrypt returned 0
6255 even though it was supposed to return -1. Fixed this. The
6256 affected file is lib/silccore/silcpacket.c.
6258 * Do not replace the config files in /etc/silc (in make install)
6259 if they already exist. Affected file ./Makefile.am.
6261 * Do not send re-key packets immediately but through packet queue.
6262 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
6264 * Changed silc_net_check_host_by_sock to return FALSE if the
6265 IP/DNS could not be resolved. Though, it returns the IP address
6266 now even if it could not resolve it (but returns also FALSE).
6267 Affected file lib/silcutil/silcnet.[ch].
6269 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

6277 contents of the specified public key file.
6279 * Changed the PKCS api to return the public key length when
6280 setting the public key.
6282 * Fixed a fatal bug in the public and private key file loading.
6283 Affected file lib/silccrypt/silcpkcs.c.
6285 * Execute the packet parsing for client with zero (0) timeout
6286 if the protocol is active. Affected file silcd/server.c.
6288 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6290 * Made the key generation options to the silcd program. Added
6291 -C option, equivalent to client's option.
6293 * Added new [ServerKeys] config section to the server. It
6294 configures the server's public and private key.
6296 * Defined generic Public Key Payload into the protocol
6297 specification to send specific type of public keys and
6300 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6301 public key or certificate.
6303 * Implemented the GETKEY command to the server and to the
6304 client library and on user interface.
6306 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

6310 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6312 * Added SilcServerRekey context into silcd/idlist.h.
6314 * Added the PFS support as defined in the specification to the
6315 SKE protocol. Affected files lib/silcske/*.c.
6317 * Added `ske_group' field to the SilcServerRekey context to hold
6318 the number of the SKE group that is used with PFS in re-key.
6319 Affected file silcd/idlist.h.
6321 * Added PFS re-key support to the server. Affected file is
6324 * Added silc_protocol_cancel to cancel execution of the next
6325 state of the protocol. Affected file is
6326 lib/silccore/silcprotocol.[ch].
6328 * Added the re-key support with and without PFS to the client
6329 library. Re-key is performed once in an hour, by default.
6331 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6332 Added silc_client_rekey_callback and silc_client_rekey_final.
6333 Affected files are lib/silcclient/protocol.[ch] and
6334 lib/silcclient/client.[ch].
6336 * Removed the `hmac_key' and `hmac_key_len' fields from the
6337 SilcClientConnection structure; not needed. Affected file is
6338 lib/silcclient/client.h.
6342 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6344 * Do not ask whether user wants to use the negotiated private key
6345 for private messages, just use it. Affected file is
6346 silc/local_command.c.
6348 * Added `send_enc_key' and `enc_key_len' fields to the
6349 SilcIDListData structure since they are needed in the re-key
6350 phase. Affected file is silcd/idlist.[ch].
6352 * Implemented the simple re-key protocol into the server.
6353 Affected files silcd/server.c and silcd/protocol.[ch]. The
6354 re-key will be performed once in an hour, by default.
6356 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6357 Added silc_server_rekey, silc_server_rekey_callback and
6358 silc_server_rekey_final.
6360 * Removed Tunneled flag from the protocol. Updated the code
6361 and the specifications.
6363 * Adde `pfs' field to the SilcIDListData to indicate whether
6364 the PFS is to be performed in the re-key. Affected file is
6367 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6369 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6370 int64 of at least the xintXX size. If void * is less that 4
6371 bytes uint32 * will be used. Defined bool as boolean.
6373 * Changed _ALL_ unsigned long and unsigned int to uint32,
6374 unsgined short to uint16 in the source tree.
6376 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6377 not handle clients that has entry->data.registered == FALSE.
6378 They are not in the network anymore. Affected file is
6381 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6383 * Implemented the sending of the SERVER_SIGNOFF notify in the
6384 server. Affected file is silcd/server.c.
6386 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6387 Added also silc_notify_payload_encode_args into the
6388 lib/silccore/silcnotify.[ch].
6390 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6391 Affected file silcd/packet_receive.c.
6393 * Implemented the SERVER_SIGNOFF notify handling in the client
6394 library. Affected file lib/silcclient/client_notify.c. Also,
6395 implemnted the printing of the SERVER_SIGNOFF info to the
6396 application. Affected file silc/client_ops.c.
6398 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6399 if the deleting was successful. Affected file silcd/idlist.[ch].
6401 * Added support for public key authentication in the connection
6402 authentication protocol in the client library. Affected file
6403 lib/silcclient/protocol.c.
6405 * Changed the server's silc_idlist_get_clients_by_* interface
6406 to support already allocated array so that new entries may be
6407 added to pre-allocated array. Affected file silcd/idlist.[ch].
6408 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6409 and command replies.
6411 * All command reply functions in the server now calls the
6412 pending command callback even if error occured. This way the
6413 error will be delivered to the client as well. Affected files
6414 silcd/command.c and silcd/command_reply.c.
6416 * Fixed INFO command to return local server's info if no server
6417 was provided. Affected file lib/silcclient/command.c.
6419 * Removed RESTART command for good. Updated the code and the
6422 * Rewrote parts of the task system. It is a bit simpler now.
6423 Removed unsued task priorities. The affected files are
6424 lib/silcutil/silctask.[ch].
6426 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6428 * Moved the USERS printing from the library to the application.
6429 Affected files lib/silcclient/command.c and silc/client_ops.c.
6431 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6435 * Added channel key re-key support. The re-key is perfomed
6436 only by the router and is done once in an hour. Added `rekey'
6437 field to the SilcChannelEntry in the server. Affected files
6438 silcd/server.c and silcd/idlist.h.
6440 * Added silc_task_unregister_by_context into the file
6441 lib/silcutil/silctask.[ch].
6443 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6445 * Added SILC_UMODE_GONE mode to indicate when the client is not
6446 present in the SILC network. Added also support to the local
6447 command AWAY that will set this mode. Added support of showing
6448 "xxx is gone" in WHOIS command. The USERS command shows the
6449 gone status as well.
6451 * Fixed setting server and router operator privileges in the
6452 server's UMODE command. Affected file silcd/command.c.
6454 * Merged the SKE KE1 and KE2 payloads into one payload. The
6455 new KE payload is equivalent to the old KE2 payload.
6457 Cleaned up the SKE Start Payload parsing. It now uses the
6458 simple buffer unformatting to do the parsing. A lot faster
6461 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6462 to the SKE that is used to indicate whether both of the SKE
6463 parties should perform authentication. By default only the
6464 responder performs authentication. By setting this flag also
6465 the initiator must do authentication. By default it is unset
6466 since in normal SKE case, client to server connection, only
6467 the responder should do authentication. When doing SKE between
6468 two clients both should perform authentication. Updated the
6469 code and the protocol specs.
6471 * A little fix to IDENTIFY command in the server. Search the
6472 client first by hash not nickname. Affected file is
6475 * Fixed the silc_client_close_connection to support closing
6476 the client to client connections wihtout deleting too much
6477 data. Affected file lib/silcclient/client.c.
6479 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6480 are received if protocol used to be active but is not anymore
6481 the application would crash due to NULL pointer dereference.
6482 Affected files silcd/server.c and lib/silcclient/client.c.
6484 * Added `hash' field to the SilcClientConnection to include
6485 the hash function negotiated in the SKE protocol.
6487 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6488 to set the channel founder authentication data. A client can
6489 claim the founder rights later by providing the authentication
6490 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6491 This way the channel founder can regain the channel founder
6492 privileges even it is left the channel. This works only on
6493 local server and the client must be connected to the same
6494 server to be able to regain the founder rights. Updated the
6495 protocol specs accordingly.
6497 Added support to the CMODE command in the client to set the
6498 founder auth data. Read the README to see how to set it.
6500 Added support to the CUMODE command to claim the founder
6501 rights. Read the README to see how to do it.
6503 Added support for the founder authentication to the Channel
6504 Entry in the server. Affected file silcd/idlist.h.
6506 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6507 server's CMODE command. Affected file silcd/command.c.
6509 * Added the following new functions into lib/silccore/silcauth.[ch]:
6510 silc_auth_get_method and silc_auth_get_data.
6512 * The server now saves the remote hosts public key to the
6513 SilcIDListData pointer. Affected file silcd/protocol.c.
6515 * The normal server now does not remove the channel entry from
6516 the cache if the founder authentication data is set. It used
6517 to remove it if the founder was the last one on the channel on
6518 the server and left the channel. The auth data is saved and
6519 if the channel is re-joined later the old entry is used with
6520 the old auth data. Affected files silcd/command_reply.c and
6523 * Removed the `pkcs' field from the SilcIDListData structure
6524 in the server; it is not used. Affected file silcd/idlist.h.
6526 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6528 * Fixed packet processing on slow links. Partial packets were
6529 never re-processed because the incoming data buffer was cleared
6530 by the application. Application must not directly clear the
6531 sock->inbuf, the packet processing routines handle it. Fixed
6532 this in client library and in server.
6534 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6536 * Fixed the WHOIS and IDENTIFY send reply function to really
6537 check whether to send list or just one entry. Affected file
6540 * Cleaned up the LEAVE command's channel key distribution. The
6541 affected file silcd/command.c.
6543 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6544 can enforce the channel mode as well. In that case the ID
6545 includes the ID of the server. The code now enforces the
6546 mode change if the router have different mode than the server.
6548 * The notify client operation with CMODE_CHANGE notify can now
6549 return NULL client_entry pointer if the CMODE was not changed
6550 by client. Application must check for this.
6552 * Added <Server ID> argument to INFO command to support server
6553 info fetching by Server ID.
6555 * Added silc_server_announce_get_channel_users to get assembled
6556 packets of channel users of the specified channel. Affected
6557 file silcd/server.[ch].
6559 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6560 was freed underneath the ID Cache.
6562 * Re-announce clients when the server received CHANNEL_CHANGE
6563 notify from the router. Affected file silcd/packet_send.c.
6565 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6567 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6568 crashed since it did not handle the fact that there is no cipher
6569 called "3" and didn't check the error condition. Now fixed.
6571 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6572 flag. It can be used to send message requests.
6574 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6576 * Implemented the RESTART command in the client.
6578 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6579 notice type messages. Added notice printing to the user
6582 * The channel keys are not re-generated if the channel's mode
6583 is PRIVKEY, ie private key on the channel exists. Affected
6584 files silcd/server.c and silcd/command.c.
6586 * Fixed a little bug in channel message delivery when channel
6587 private keys are set in the server. Affected file is
6588 silcd/packet_send.c.
6590 * Changed the setting on channel->on_channel = TRUE from the
6591 silc_client_save_channel_key to the JOIN command reply. The
6592 key payload is not received if the private channel key is set.
6593 Affected file lib/silcclient/command_reply.c and the
6594 lib/silcclient/client_channel.c.
6596 * When the CMODE_CHANGE notify is sent and the channel private
6597 key mode is removed the channel key must be re-generated in
6598 other cells as well. Added this support for the router in the
6599 silcd/packet_receive.c.
6601 * Added new local command NOTICE to send notice message on
6602 channel. Affected file silc/local_command.[ch].
6604 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6606 * Added new local command ME to the client. It is used to send
6607 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6608 some action. Affected file silc/local_command.[ch].
6610 * Changed channel_message and private_message client operations
6611 to deliver the message flags to the application. Added also
6612 the `flags' arguments to the silc_client_send_channel_message
6613 and silc_client_send_private_message functions. Affected file
6616 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6618 * Redefined the Private Message Payload to support private message
6619 keys and to support the new private message flags. Updated
6620 the protocol specs. Flags makes it possible to have for example
6621 CTCP style messages.
6623 * Added new type SilcPrivateMessagePayload and defined an API
6624 for it in the lib/silcclient/silcprivate.[ch].
6626 * Tested private message private keys successfully. Tested the
6627 private message key set, unset and list commands with the new
6630 * Redefined the Channel Message Payload to include the channel
6631 message flags (equal with private message flags) to support
6632 for example CTCP style messages.
6634 * Defined some of the message (for channel and private message)
6635 flags. Updated the protocol specs and added the flags to the
6636 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6638 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6640 * Added SilcKeyAgreementStatus type to the key agreement routines
6641 to indicate the current status and error if one occured.
6642 The status types are defined in the lib/silcclient/silcapi.h.
6644 * Added new local command KEY that is used to set and unset private
6645 keys for channels, set and unset private keys for private messages
6646 with remote clients and to send key agreement requests and
6647 negotiate the key agreement protocol with remote client. The
6648 key agreement is supported only to negotiate private message keys,
6649 it currently cannot be used to negotiate private keys for channels,
6650 as it is not convenient for that purpose.
6652 * Fixed a minor pending callback setting bug in the function
6653 silc_client_get_client_by_id_resolve, now the function works.
6654 Affected file lib/silcclient/idlist.c.
6656 * Added function silc_net_get_local_port to get local bound
6657 port by socket. Added to lib/silcutil/silcnet.[ch].
6659 * Added `sockets' and `sockets_count' fields to the SilcClient
6660 object. They hold the sockets of the listenning sockets in
6661 the client. Listenning sockets may be for example the key
6662 agreement server. Affected file lib/silcclient/client.[ch].
6663 Added functions the silc_client_add_socket and the
6664 silc_client_del_socket. They are exported to the application
6667 * Added ~./silc/clientkeys to support other client's public keys.
6669 * Renamed verify_server_key client operation to verify_public_key
6670 and added one argument to indicate the type of the connection
6671 (server, client etc.).
6673 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6675 * Added silc_server_connection_auth_request to handle the
6676 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6677 silcd/packet_receive.[ch].
6679 * Added silc_server_send_connection_auth_request into the
6680 silcd/packet_send.c to send the connection auth request packet.
6682 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6685 * Fixed the public key authentication in responder side in the
6686 server. The `auth_data' pointer includes the SilcPublicKey
6687 not the path to the public key. Affected file silcd/protocol.c.
6689 * Implemented the public key authentication in the initiator side
6690 in the server. Affected file silcd/protocol.c.
6692 * Removed the [RedirectClient] config section from the server
6693 configuration. Is not needed and I don't want to implement it.
6695 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6697 * Cleaned up the CMODE command in the server. It now works
6698 correctly and supports all the modes defined in the protocol.
6699 Affected file is silcd/command.c.
6701 * Added `hmac_name' field to the SilcChannelEntry in the server
6702 to hold the default HMAC of the channel. It can be set when
6703 creating the channel (with JOIN command). Affected files
6706 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6707 type to indicate the change of the current cipher and hmac
6708 on the channel. Client can safely ignore the <cipher> argument
6709 (if it chooses to do so) since the CHANNEL_KEY packet will
6710 force the channel key change anyway. The <hmac> argument is
6711 important since the client is responsible of setting the new
6712 HMAC and the hmac key into use.
6714 * Fixed the CMODE command in the client library as well.
6716 * Tested CMODE command in router environment successfully.
6718 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6720 * Show the version of the remote client (or server) when connecting
6721 to the server. It is logged to the log file. Affected file
6722 is silcd/protocol.c.
6724 * Fixed the KILLED notify handling in the client library. The
6725 client must be removed from all channels when receiving the
6728 Also, do not remove the client entry when giving the KILL
6729 command but when the KILLED notify is received.
6731 * Removed silc_idlist_find_client_by_nickname from the server.
6732 Not needed anymore. Affected files silcd/idlist.[ch].
6734 * Implemented the CHANNEL_CHANGE notify type handling to the
6735 server. Affected file silcd/server.c.
6739 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6741 * Added silc_server_send_notify_invite to send the INVITE
6742 notify between routers.
6744 * Implemented the INVITE command correctly to the server.
6746 * Implemented the INVITE notify type handling in the server.
6748 * Implemented the INVITE command to the client library and on the
6751 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6753 * Added function silc_server_get_client_resolve to find the
6754 client entry by ID from all ID lists and then resolve it
6755 (using WHOIS) if it cannot be found. Affected file is
6758 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6760 * Implemented the BAN command to the client library.
6762 * The JOIN command in the server now checks the invite list
6765 * Changed the silc_command_reply_payload_encode_va and the
6766 silc_command_payload_encode_va to support that if argument is
6767 NULL it ignores and checks the next argument. Affected file
6768 lib/silccore/silccommand.c.
6770 * Added silc_server_send_notify_ban to send the BAN notify
6771 type between routers.
6773 * Chaned the silc_notify_payload_encode to support that if
6774 argument is NULL it ignores and checks the next argument.
6775 Affected file lib/silccore/silcnotify.c.
6777 * Tested ban lists in router environment successfully.
6779 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6781 * Implemented BAN command to the server, in silcd/command.[ch].
6783 * Removed the BAN and INVITE_LIST modes from the CMODE command
6786 * Added function silc_string_match to regex match two strings.
6787 Affected files lib/silcutil/silcutil.[ch].
6789 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6791 * Redefined parts of the SilcChannelEntry in the server to support
6792 the new ban and invite lists.
6794 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6796 * Redefined the INVITE command. The same command can be used to
6797 invite individuals to the channel but also to manage the invite
6798 list of the channel (to add to and remove from the invite list).
6799 Updated the protocol specs.
6801 * Added new command SILC_COMMAND_BAN that can be used to manage
6802 the ban list of the channel. Updated the protocol specs.
6804 * Removed the channel modes: the SILC_CMODE_BAN and the
6805 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6806 in the CMODE command. The equivalent features are now available
6807 using INVITE and BAN commands. Updated the protocol specs.
6809 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6810 in the network about change in the current ban list. The notify
6811 type is not used by the client.
6813 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6814 support the invite lists.
6816 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6818 * Added new function silc_string_regexify that converts string
6819 including wildcard characters into regex string that can
6820 be used by the GNU regex library. Added into the file
6821 lib/silcutil/silcutil.[ch].
6823 Added silc_string_regex_combine to combine to regex strings
6824 into one so that they can be used as one regex string by
6825 the GNU regex library. Added into the file
6826 lib/silcutil/silcutil.[ch].
6828 Added silc_string_regex_match to match two strings. It returns
6829 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6831 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6833 * Imported GNU regex to the soruce tree into lib/contrib.
6834 Fixed some compiler warning from the regex.c.
6836 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6838 * Fixed MOTD command in the server to work in router environment.
6840 * Fixed the MOTD command in the client library to support
6841 the server argument in the command.
6843 * Added `nickname_len' argument to the silc_idlist_add_client
6844 in the server, as the `nickname' argument may be binary data
6847 * Added silc_idlist_get_channels to return all channels from
6850 * Implemented LIST command to the server. Affected file is
6853 * Implemented the LIST command to the client library and on the
6856 * Added [<user count>] argument to the LIST command reply.
6857 With private channels the user count is not shown.
6859 * Updated TODO and README.
6861 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6863 * The client entry's data.registered must be TRUE even with
6864 global client entry on global client list. The data.registered
6865 is used to check whether the client is anymore in the network,
6866 for example with WHOWAS command so it must be valid.
6868 * Fixed the WHOWAS command in the server. It now actually works
6869 in router environment. Added function into silcd/command_reply.c
6870 silc_server_command_reply_whowas_save.
6872 * Added silc_idlist_purge function to the silcd/idlist.c
6873 to periodically purge the ID Cache.
6875 * Fixed INFO command in the server. It works now in router
6876 environment. Added <server name> argument to the INFO command
6877 reply. Updated the protocol specs.
6879 * Fixed minor bug in silc_idcache_purge to not purge if the
6880 expire value is zero.
6882 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6883 they were buggy because of the WHOWAS information.
6885 * Fixed local command MSG to handle the async resolving of
6886 the remote client properly. It used to fail the first MSG.
6887 Affected file silc/local_command.c.
6889 * Added `data_len' field to SilcIDCache context.
6891 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6893 * Update TODO. Todo in commands in the server.
6895 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6897 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6898 used by routers as broadcast packet to inform other routers
6899 about the changed user mode.
6901 Implemented the notify handling in the server. Affected file is
6902 silcd/packet_receive.c. Added the function
6903 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6905 * Added new generic Channel Payload and deprecated the New Channel
6906 Payload. The New Channel Payload is now the generic Channel
6909 * Added new argument `mode' to the silc_server_send_new_channel
6910 as it is required in the Channel Payload now.
6912 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6913 and created a new and real SilChannelPayload to represent the
6914 new generic Channel Payload. Implemented the encode/decode
6915 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6917 * Added silc_server_get_client_channel_list to return the list
6918 of channels the client has joined for WHOIS command reply.
6919 Affected file silcd/server.[ch].
6921 * Implemented the channel list sending in the WHOIS command reply
6922 in server and in the client.
6924 Implemented the channel list displaying on the user interface
6925 as well. Affected file silc/client_ops.c.
6927 * Added silc_channel_payload_parse_list to parse list of Channel
6928 Payloads. It returns SilcDList list of SilcChannelPayloads.
6929 Client for example can use this function to parse the list of
6930 channels it receives in the WHOIS command reply. The caller
6931 must free the list by calling silc_channel_payload_list_free.
6932 Affected files lib/silccore/silcchannel.[ch].
6934 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6936 * Added one new argument <user mode> to the WHOIS command reply
6937 to return the mode of the user in SILC. Updated the protocol
6940 Implemented it to the server and client.
6942 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6944 * Fixed the mode printing on the user interface on joining.
6945 Affected file silc/client_ops.c.
6947 * Implemented the UMODE command and user modes in general to the
6948 client library and to the user interface.
6950 * Implemented the UMODE command to the server.
6952 * The server now sends UNKNOWN_COMMAND error status if client sends
6953 unknown command. Affected file silcd/command.c.
6955 * All server commands now handle the command identifier the right
6956 way when sending the command reply to the client. The client can
6957 use to identify the command replies with the identifier.
6959 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6961 * Added silc_server_get_client_route to resolve the route to
6962 the client indicated by the client ID. Affected file is
6965 * Added silc_server_relay_packet as general function to relay
6966 packet to arbitrary destination. This deprecates functions
6967 like _send_private_message_key, _relay_notify etc. Affected
6968 file is silcd/packet_send.[ch].
6970 Removed silc_server_send_key_agreement,
6971 silc_server_send_private_message_key and
6972 silc_server_packet_relay_notify functions from the file
6973 silcd/packet_send.[ch].
6977 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6978 server. Affected file silcd/packet_receive.[ch].
6980 * Implemented the KILL command to the client. Implemented the
6981 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6982 Affected files lib/silcclient/command[_reply].c and
6983 lib/silcclient/client_notify.c. Implemented the KILL notify
6984 printing in the user inteface.
6986 * Fixed a lot silc_parse_nick memory leaks from the client
6987 library in the file lib/silcclient/command.c.
6989 * Changed the silc_server_send_notify_on_channels's `sender'
6990 argument from SilcSocketConnection to SilcClientEntry to
6991 check the sender as entry and not as connection object and not
6992 to send to the client provided as argument. The affected file
6993 is silcd/packet_send.[ch].
6995 * The notify packets that are destined directly to the client used
6996 to not to be processed by the server. Now changed that and the
6997 server processes all notify packets. After relaying the packet
6998 to the client the notify packet is processed in the server.
7000 * The silc_server_free_client_data now checks whether there is
7001 pending outgoing traffic for the client and purges the data to
7002 the network before removing the client entry.
7004 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7006 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
7007 an client is killed from the SILC Network. Updated the protocol
7010 Added new function silc_server_send_notify_killed to the
7011 silcd/packet_send.[ch].
7013 * Added function silc_server_packet_relay_notify to relay notify
7014 packets that are destined directly to a client. In this case
7015 the server does not process the notify packets but merely relays
7016 it to the client. Affected file silcd/packet_send.[ch].
7018 Added also silc_server_packet_process_relay_notify to check
7019 whereto relay the notify. Affected file is
7020 silcd/packet_receive.[ch].
7022 * Implemented the KILL command to the server.
7026 * Added the backup schema desgined last fall to the protocol
7027 specs for everyone to see. The specification is in the
7028 *-spec-xx.txt draft and the packet type definitions for the
7029 backup routers is in *-pp-xx.txt draft. Thusly, added also
7030 new packet type SILC_PACKET_CELL_ROUTERS.
7032 * A big security problem in the implementation discovered. The
7033 signoff of an client did not cause new channel key generation
7034 which it of course should've done. The channel keys must be
7035 always re-generated when client leaves (or signoffs) the channel.
7036 The silc_server_remove_from_channels funtion now handles
7037 the channel key re-generation.
7039 * Added `sender' argument to the silc_server_send_notify_on_channels
7040 to not to send the client provided as argument. Affected file
7041 silcd/packet_send.[ch].
7043 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7045 * Implemented OPER and SILCOPER commands into the server and
7048 * Added silc_auth_verify and silc_auth_verify_data to verify
7049 the authentication directly from the authentication payload.
7050 It supports verifying both passphrase and public key based
7051 authentication. Affected file lib/silccore/silcauth.[ch].
7053 * Added `hash' field to the SilcIDListData structure. It is the
7054 hash negotiated in the SKE protocol. Affected file is
7057 * Slight redesigning of the SilcAuthPayload handling routines.
7058 Do not send SilcPKCS but SilcPublicKey as argument.
7060 * Implemented the public key authentication support to the
7061 serverconfig. The public key is loaded from the provided path
7062 and saved as authentication data to void * pointer. Thus,
7063 changed the unsigned char *auth_data to void *auth_data;
7065 * Fixed SHUTDOWN command to send the reply before the server
7066 is shutdown. :) Affected file silcd/command.c.
7068 * Fixed fatal bug in CONNECT command. The hostname was invalid
7069 memory and server crashed. Affected file silcd/command.c.
7071 * Fixed fatal bug in CLOSE command. The server_entry became
7072 invalid but was referenced later in the command. Affected file
7075 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7077 * Fixed fatal bug in failure packet handling. Server ignored
7078 the failure and thus crashed when it came.
7082 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7084 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
7085 that the command may be executed only once in (about) 2 seconds.
7086 The old SILC_CF_LAG flag is same but allows command bursts up
7087 to five before limiting.
7089 Added the support for CF_LAG and CF_LAG_STRICT flags to the
7090 server code. Various commands now includes the CF_LAG_STRICT
7091 flag to disallow any kind of miss-use of the command.
7093 * Fixed the silc_buffer_unformat to not to allocate any data
7094 if the length of the data is zero. It used to allocate the
7095 length + 1. Affected file lib/silcutil/silcbuffmt.c.
7097 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7099 * Changed the format of AdminConnection configuration section
7100 in the server. Added username of the admin to the format.
7101 Affected files silcd/serverconfig.[ch].
7103 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
7104 to return admin configuration data by host, username and/or
7107 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7109 * Implemented WHOWAS command to the server. Added the functions:
7111 silc_server_command_whowas_parse,
7112 silc_server_command_whowas_send_reply,
7113 silc_server_command_whowas_from_client and
7114 silc_server_command_whowas_from_server
7116 * Added <Client ID> argument to the WHOWAS command reply. Updated
7117 the protocol specs accordingly.
7119 * Implemented WHOWAS command and command_reply to the client
7122 Implemented the WHOWAS printing on the user interface.
7124 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7126 * Added new argument to the WHOWAS command reply, the real name.
7127 It is an optional argument. Updated the protocol specs.
7129 * Added SilcIDCacheDestructor callback that is registered when
7130 the SilcIDCache is allocated. The callback is called when
7131 an cache entry in the ID Cache expires, or is purged from the
7132 cache. Added into lib/silccore/idcache.[ch].
7134 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
7135 to destruct the client entries when the cache entry expires.
7136 Other ID Cache's in server and in the client library ignores
7139 * If the ID Cache entry's `expire' field is zero then the entry
7140 never expires. Added boolean `expire' argument to the
7141 silc_idcache_add function in the lib/silccore/idcache.[ch].
7142 If it is TRUE the default expiry value is used.
7144 * Added silc_server_free_client_data_timeout that is registered
7145 when client disconnects. By default for 5 minutes we preserve
7146 the client entry for history - for WHOWAS command.
7148 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7150 * Added support to the server to enforce that commands are not
7151 executed more than once in 2 seconds. If server receives
7152 commands from client more frequently, timeout is registered
7153 to process the commands. Affected file silcd/command.c.
7154 Added new function silc_server_command_process_timeout.
7156 * Changed NICK_NOTIFY handling in client library to check that
7157 if the client's nickname was changed, so there is no need to
7158 resolve anything from the server.
7160 * Removed error printing from the WHOIS and IDENTIFY commands.
7161 If error occurs then it is ignored silently in the client library.
7162 The application, however, may map the received error to
7163 human readable error string. The application currently maps
7164 the NO_SUCH_NICKNAME error to string.
7166 * Made the command status message public to the application. Moved
7167 them from lib/silcclient/command_reply.c to
7168 lib/silcclient/command_reply.h. The application can map the
7169 received command status to the string with the
7170 silc_client_command_status_message function.
7172 * Added check to the server to check that client's ID is same
7173 as the Source ID in the packet the client sent. They must
7176 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7178 * Added dist-bzip hook to the Makefile.am to make bzip2
7179 compressed distributions.
7181 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7183 * Server now enforces the maximum length for the nickname and
7184 the channel as protocol specification dictates. 128 bytes for
7185 nickname and 256 bytes for channel name.
7187 * Moved the WHOIS printing to the application. The client libary
7188 does not print out the WHOIS information anymore, the application
7189 must do it. Renamed silc_client_command_reply_whois_print to
7190 the silc_client_command_reply_whois_save.
7192 The client's idle time is also sent to the application now, and
7193 the idle is shown on screen.
7195 * Added silc_client_command_reply_identify_save to save the
7196 received IDENTIFY entries.
7198 * Do not check for channel private keys in message sending and
7199 reception if the channel does not have the PRIVKEY mode set.
7200 Affected file lib/silclient/client_channel.c.
7202 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7204 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
7205 just surfaced after chaning the JOIN procedure.
7207 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7209 * Added silc_client_get_clients_by_list to get client entries
7210 from Client ID list, that is returned for example by JOIN
7211 and USERS command replies. The application should use this
7212 function for example when JOIN command reply is received to
7213 resolve the clients already on the channel (library does not
7214 do that anymore as USERS command reply is not used in the JOIN
7215 procedure anymore). Affected files lib/silcclient/silcapi.h and
7216 lib/silcclient/idlist.c.
7218 * JOIN command reply and USERS command reply returns now SilcBuffer
7219 pointers instead of unsigned char pointers when returning
7220 the client list and mode list.
7222 * Added <Client ID> argument to the JOIN command reply, mainly
7223 for the server to identify for which client the command was
7224 originally sent. Updated protocol specs accordingly.
7226 * Added SilcDlist private_key pointer to the SilcChannelEntry
7227 in the client to support the channel private keys. Affected
7228 file is lib/silcclient/idlist.h.
7230 * Added SilcChannelPrivateKey argument to the function
7231 silc_client_send_channel_message so that application can choose
7232 to use specific private ke if it wants to. If it is not provided,
7233 the normal channel key is used, unless private keys are set.
7234 In this case the first (key that was added first) is used
7235 as the encryption key.
7237 * Implemented the support for channel private key handling.
7238 Implemented the following functions:
7240 silc_client_add_channel_private_key,
7241 silc_client_del_channel_private_keys,
7242 silc_client_del_channel_private_key,
7243 silc_client_list_channel_private_keys and
7244 silc_client_free_channel_private_keys
7246 Affected file lib/silcclient/client_channel.c.
7248 * Added the support for the private keys in the channel message
7249 sending and encryption and in the message reception and
7250 decryption. Affected funtions are
7251 silc_client_send_channel_message and silc_client_channel_message.
7253 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7255 * Added SKE's key verify callback to the client library's
7256 KE protocol context. Affected files lib/silcclient/protocol.[ch].
7258 * Removed the statement that server (or router) must send USERS
7259 command reply when joining to the channel so that the client
7260 knows who are on the channel. Instead, the client list and
7261 client's mode list is now sent in the JOIN command reply to the
7262 client who joined channel. This is better solution.
7264 * Added function silc_server_get_users_on_channel and function
7265 silc_server_save_users_on_channel to the silcd/server.[ch].
7267 * Removed function silc_server_command_send_users from the
7270 * Do not show topic on the client library anymore. The topic is
7271 sent in the command reply notify to the application and the
7272 application must show the topic now.
7274 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7276 * Added client searching by nickname hash into the IDENTIFY and
7277 WHOIS commands in the server as they were clearly missing from
7278 them. Affected file is silcd/command.c.
7280 * Fixed a bug in private message receiving in the client library.
7281 The remote ID was freed and it wasn't supposed, now it is
7284 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7286 * Minor fix to the channel payload; allocate the data area, as it
7287 needs to be of specific length.
7289 * If the key agreement port is zero then the operating
7290 system will define the bound port. Affected files are
7291 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7293 * Added new function silc_channel_payload_decrypt into the file
7294 lib/silccore/silcchannel.[ch].
7296 * Moved the channel message etc, check from silc_packet_decrypt
7297 to applications. The library calls now a generic
7298 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7299 when the packet is either normal or special. This was done to
7300 allow more wide range of checking that was not allowed when
7301 the code was in library. Now applications can do virtually any
7302 checks to the packet and return to the library the decision how
7303 the packet should be processed. Affected files are
7304 lib/silccore/silcpacket.[ch].
7306 Added silc_server_packet_decrypt_check to the server and
7307 silc_client_packet_decrypt_check to the client library.
7309 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7310 to send with specified source and destination information.
7312 * Channel message delivery between routers was broken after the
7313 channel key distribution was fixed earlier. The channel key
7314 was used be to distributed to other routers as well which is not
7315 allowed by the protocol. Now this is fixed and channel keys
7316 really are cell specific and the channel message delivery between
7317 routers comply with the protocol specification.
7319 * Fixed various commands in server to check also the global list
7320 for the channel entry and not just the local list. The affected
7321 file silcd/command.c.
7323 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7325 * Added assert()s to buffer formatting and unformatting routines
7326 to assert (if --enable-debug) when error occurs. Affected
7327 file: lib/silcutil/silcbuffmt.c.
7329 * Changed to auto-reconnect to check whether the remote host is
7330 router and register the re-connect timeout if it is. It used
7331 to check that whether we are normal server, but router must do
7332 auto-reconnect with another router as well. Affected file
7335 * Removed the [<key len>] option from CMODE command as the cipher
7336 name decides the key length, nowadays. See the defined ciphers
7337 from the protocol specification.
7339 * Added [<hmac>] option to the CMODE command to define the HMAC
7340 for the channel. Added SILC_CMODE_HMAC channel mode.
7342 * Added [<hmac>] option for the JOIN command so that user can
7343 select which HMAC is used to compute the MACs of the channel
7346 * Added Hmac field to the Channel Message Payload. The integrity
7347 of plaintext channel messages are now protected by computing
7348 MAC of the message and attaching the MAC to the payload. The
7349 MAC is encrypted. Now, it is clear that this causes some
7350 overhead to the size of the packet but rationale for this is that
7351 now the receiver can verify whether the channel message decrypted
7352 correctly and also when private keys are set for the channel the
7353 receiver can decrypt the packet with several keys and check from
7354 the MAC which key decrypted the message correctly.
7356 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7357 lib/silccrypt/silccipher.[ch].
7359 * Added silc_hash_len to return the digest length into the
7360 lib/silcrypt/silchash.[ch].
7362 * Rewrote parts of Silc Channel Payload interface in the
7363 lib/silccore/silcchannel.[ch]. The encode function now also
7364 encrypts the packet and parse function decrypts it.
7366 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7368 * Fixed a minor formatting bug in the SKE's key material processing.
7369 It actually might have processed the keys wrong way resulting
7372 * Redefined the mandatory HMAC algorithms and added new algorithms.
7373 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7374 and hmac-md5 truncated to 96 bits. The mandatory is now
7375 hmac-sha1-96. Rest are optional (including the one that used
7376 to be mandatory). Rationale for this is that the truncated HMAC
7377 length is sufficient from security point of view and can actually
7378 make the attack against the HMAC harder. Also, the truncated
7379 HMAC causes less overhead to the packets. See the RFC2104 for
7382 * Added new [hmac] configuration section. The SKE used to use
7383 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7384 is of course wrong. The official names that must be proposed in
7385 the SKE are the ones defined in the protocol specification
7386 (hmac-sha1-96 for example). The user can configure any hmac
7387 using any hash function configured in the [hash] section. At
7388 least, the mandatory must be configured.
7390 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7392 * Added HMAC list to the SKE proposal list. It has now both
7393 hash algorithm list and HMAC list. This makes the protocol
7394 incompatible with previous versions. The SKE now seems to work
7395 the way it is supposed to work, for the first time actually.
7397 * Defined plain Hash algorithms to the protocol specification.
7400 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7402 * Implemented support for key agreement packets into the server.
7403 Added functions silc_server_key_agreement and
7404 silc_server_send_key_agreement. Other than these functions,
7405 server has nothing to do with this packet.
7407 * Added support for private message key packets into the server.
7408 Added functions silc_server_private_message_key and
7409 silc_server_send_private_message_key.
7413 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7414 called in the protocol's final callback instead in the END
7415 protocol state. This makes a little more sense and in the same
7416 time in client we can use the same protocol routines for normal
7417 key exchange and to key agreement packet handling as well.
7419 * Added to both client's and server's KE protocol context the
7420 SilcSKEKeyMaterial pointer to save the key material. We will
7421 bring the key material to the protocol's final callback by doing
7422 this. The final callback must free the key material.
7424 * Added SKE's packet_send callback into client's KE protocol
7425 context so that the caller can choose what packet sending function
7426 is used. This way we can use different packet sending when
7427 doing normal SKE when doing key agreement packet handling (in
7428 the key agreement packet handling we do not want to encrypt
7431 * Implemented the responder side of the key agreement routines
7432 in the client. The client can now bind to specified port and
7433 accept incoming key negotiation. The key material is passed
7434 to the application after the protocol is over.
7436 * Implemented the processing of incoming Key Agreement packet
7437 in the client. Added function silc_client_key_agreement to
7440 * Implemented the intiator side of the key agreement routines
7441 in the client. The client can now initiate key agreement with
7442 another remote client. The key material is passed to the
7443 application after the protocol is over.
7445 * Created client_keyagr.c to include all the key agreement
7448 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7449 SILC_TASK_CALLBACK except that it is not static.
7451 * Created client_notify.c and moved the Notify packet handling
7452 from the client.[ch] into that file.
7454 * Created client_prvmsg.c and moved all private message and
7455 private message key routines from the client.[ch] into that file.
7457 * Create client_channel.c and moved all channel message and
7458 channel private key routines from the client.[ch] into that file.
7460 * Changed silc_client_get_client_by_id_resolve to resolve with
7461 WHOIS command instead of IDENTIFY command, in the file
7462 lib/silclient/idlist.c.
7464 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7466 * Implemented the SKE's responder side to the Client library.
7468 * When FAILURE is received to the protocol do not trust it
7469 blindly. Register a timeout to wait whether the remote closes
7470 the connection as it should do it, only after that process the
7471 actual failure. This was changed to both client and server.
7473 * Added client_internal.h to include some of the structures
7474 there instead of client.h in lib/silcclient/.
7476 * Added function silc_task_unregister_by_callback to unregister
7477 timeouts by the callback function.
7479 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7481 * Some "Incomplete WHOIS info" errors has been appearing on the
7482 log files. Took away the entry->userinfo check from WHOIS
7483 reply sending. The entry->userinfo is now " " if client did not
7484 provide one. I thought this was fixed earlier but something
7485 is wrong still. Let's see if the error still appears.
7487 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7489 * Fixed a minor bug in the login when the channel key is
7490 re-generated in the server. It used to generate the key in
7491 wrong order and thus caused problems in the channel traffic.
7493 * Fixed a minor bug in channel key distsribution after
7494 KICK command. The key was not sent to the router even though
7497 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7499 * Added silc_ske_process_key_material_data as generic routine
7500 to process any key material as the SILC protocol dictates. The
7501 function is used by the actual SKE library but can be used by
7502 applications as well. This relates to the private message keys
7503 and the channel private keys since they must be processed the
7504 same way the normal SILC session keys. The protocol dictates
7505 this. Affected files: lib/silcske/silcske.[ch].
7507 Added also silc_ske_free_key_material to free the
7508 SilcSKEKeyMaterial structure.
7510 * Defined silc_cipher_set_key function to set the key for
7511 cipher without using the object's method function. The affected
7512 files: lib/silccrypt/silccipher.[ch].
7514 * Implemented silc silc_client_add_private_message_key,
7515 silc_client_add_private_message_key_ske,
7516 silc_client_del_private_message_key,
7517 silc_client_list_private_message_keys and
7518 silc_client_free_private_message_keys functions in the
7521 Added functions silc_client_send_private_message_key to send
7522 the Private Message Key payload and silc_client_private_message_key
7523 to handle incoming Private Message Key payload.
7525 * Added Cipher field to the Private Message Key payload to set
7526 the cipher to be used. If ignored, the default cipher defined
7527 in the SILC protocol (aes-256-cbc) is used.
7529 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7531 * Removed lib/silcclient/ops.h file.
7533 Redefined parts of the SILC Client Library API. Created new
7534 file silcapi.h that deprecates the ops.h file and defines the
7535 published Client Library API. Defined also private message key
7536 API and channel private key API into the file.
7538 This is the file that the application must include from the
7539 SILC Client Library. Other files need not be included by
7540 the application anymore.
7542 * Added new key_agreement client operation callback and also
7543 defined the Key Agreement library API for the application.
7545 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7547 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7548 is used by clients to request key negotiation between another
7549 client in the SILC network. If the negotiation is started it
7550 is performed using the SKE protocol. The result of the
7551 negotiation, the secret key material, can be used for example
7552 as private message key.
7554 Implemented the Key Agreement payload into the files
7555 lib/silccore/silauth.[ch].
7557 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7559 * Redefined ciphers for the SILC protocol. Added some new ciphers
7560 and defined the key lengths for the algorithms. Changed the
7561 code accordingly. The default key length is now 256 bits.
7563 * Fixed SKE key distribution function silc_ske_process_key_material
7564 when the key length is more than 128 bits. The default key
7565 length in SILC is now 256 bits.
7567 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7568 to indicate unsupported algorithm.
7570 * Renamed rijndael.c to aes.c and all functions as well.
7572 * Fixed a long standing channel key setting bug in client library.
7573 Weird that it has never surfaced before.
7575 * Fixed bug in channel deletion. If the entire channel is removed
7576 then it must also delete the references of the channel entry
7577 from the client's channel list as the client's channel entry and
7578 the channel's client entry share same memory.
7580 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7582 * Implemented CONNECT and SHUTDOWN commands in the client.
7584 * Implemented CLOSE command to the client.
7586 * Added the function silc_idlist_find_server_by_name into the
7587 files silcd/idlist.[ch].
7589 Added the function silc_idlist_find_server_by_conn into the
7590 files silcd/idlist.[ch].
7592 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7594 * DIE command was renamed to SHUTDOWN. Updated the both code
7597 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7598 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7600 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7603 * Added function silc_server_create_connection function to create
7604 connection to remote router. My server implementation actually
7605 does not allow router to connect to normal server (it expects
7606 that normal server always initiates the connection to the router)
7607 so the CONNECT command is only good for connecting to another
7610 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7612 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7613 or some other client was kicked from the channel.
7615 Implemented the handling of the notify type to both client
7618 Implemented silc_server_send_notify_kicked to send the KICKED
7619 notify. It is used to send it to the server's primary router.
7621 * Implemented the KICK command into server and client.
7623 * Added `query' argument to the silc_idlist_get_client function
7624 to indicate whether to query the client from server or not if
7627 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7628 to indicate that the client is not channel founder.
7632 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7634 * Removed the rng context from SilcPacketContext structure and
7635 changed that the packet routine uses the Global RNG API.
7637 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7639 * Added support for quit message that client can "leave" on the
7640 channel when it quits the SILC. It is ditributed inside the
7641 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7643 Added silc_server_free_client_data that will take the
7644 signoff message as argument.
7646 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7648 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7650 * Updated parts of the protocol specification to keep it up
7653 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7655 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7656 payloads in one packet.
7658 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7659 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7660 use now the new List flag.
7662 * Also deprecated the following packet types: REPLACE_ID,
7663 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7665 * Added list support for Notify packet in server.
7667 * Added silc_server_send_notify_channel_change to send the
7668 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7669 the silc_server_send_replace_id.
7671 * Added silc_server_send_notify_nick_change to send the
7672 NICK_CHANGE notify type. Deprecates the function
7673 silc_server_send_replace_id.
7675 * Added silc_server_send_notify_join to send the JOIN notify type.
7676 Deprecates the function silc_server_send_new_channel_user.
7678 * Added silc_server_send_notify_leave to send LEAVE notify type.
7679 Deprecates the function silc_server_send_remove_channel_user.
7681 * Added silc_server_send_notify_cmode and
7682 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7683 types. Deprecates the silc_server_send_set_mode function.
7685 * Added SERVER_SIGNOFF notify type to indicate that server has
7686 quit. This means that all clients on the channel from that
7687 server will drop. This can be also used when netsplit happens.
7689 Deprecated REMOVE_ID packet type since it is not needed anymore
7692 Added silc_server_send_notify_server_signoff to send the
7693 SERVER_SIGNOFF notify type. Deprecates the function
7694 silc_server_send_remove_id.
7696 Added also silc_server_send_notify_signoff to send the
7697 SIGNOFF notify type.
7699 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7700 SILC protocol from this day on. Changed the protocol
7701 specification as well.
7703 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7704 notify type. It is used between routers to notify about
7705 topic changes on a channel.
7707 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7710 * Partly updated the protocol specification to comply with the
7711 changes now made. It is still though a bit outdated.
7713 * The JOIN notify type now takes one extra argument <Channel ID>.
7714 The packet used to be destined to the channel but now the
7715 JOIN type may be sent as list thus it is impossible to
7716 destine it to any specific channel. By adding this argument
7717 it is again possible.
7719 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7721 * Added CREDITS file. The CHANGES and CREDITS file will appear
7722 in the distribution as well.
7724 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7726 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7727 types in the server's silcd/packet_receive.c.
7729 * Implemented CMODE and CUMODE to work in router environment.
7731 * Fixed minor encoding and decoding buglet from the
7732 lib/silccore/silcmode.c.
7734 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7737 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7739 * Changed all SilcConfigServer* and silc_config_server* to
7740 SilcServerConfig* and silc_server_config*, respectively.
7743 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7745 * Associated the ID (client or server ID) to the Authentication
7746 Payload to avoid any possibility of forging. Updated the
7747 protocol specification and the code accordingly.
7749 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7751 * The RSA key length is now save to the RsaKey context in the
7752 key generation process in lib/silccrypt/rsa.c. The key length
7753 is now used to figure out the maximum size of the block allowed
7754 to be encrypted/signed.
7756 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7757 is equivalent to the silc_mp_mp2bin but does not allocate any
7760 * Changed silc_mp_mp2bin API to take length argument. If it is
7761 non-zero then the buffer is allocated that large. If zero, then
7762 the size is approximated using silc_mp_sizeinbase, which however
7765 * Created Global RNG API which is global RNG that application can
7766 initialize. After initializing, any routine anywhere in the
7767 code (including library) can use RNG without allocating a new
7768 RNG object. This was done to allow this sort of use of the
7769 RNG in code that has no chance to allocate RNG object. All
7770 applications currently allocate this and many routines in the
7771 library use this. Affected file lib/silccrypt/silcrng.[ch].
7773 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7774 it to use the Global RNG API.
7776 * Defined Authentication Payload into protocol specification that
7777 is used during SILC session to authenticate entities. It is
7778 used for example by client to authenticate itself to the server
7779 to obtain server operator privileges.
7781 Implemented this payload into the lib/silccore/silcauth.[ch].
7782 Implemented also routines for public key based authentication
7783 as the new protocol specification dictates.
7785 Moved definitions of different authentication methods from
7786 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7788 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7789 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7790 silc_pkcs_verify_with_hash functions into the file
7791 lib/silccrypt/silcpkcs.[ch].
7793 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7795 * The client entry's userinfo pointer must be always valid.
7796 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7797 will fail since it requires the userinfo. Now, the userinfo
7798 is allocated as "" if actual userinfo does not exist. Actually,
7799 it must exist and it is totally Ok to drop client connections
7800 that does not announce the userinfo. However, we will make
7801 this workaround for now.
7803 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7804 to return the remote port by socket.
7806 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7808 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7809 SILC_SERVER_PENDING_EXEC and added an new macro
7810 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7811 data or when error occurs while processing the pending command.
7813 Added new argument `destructor' into silc_server_command_pending
7814 and to the SilcServerCommandPending object. This destructor is
7815 now called after calling the pending callback or if error occurs
7816 immediately. If error occurs the actual pending callback won't
7817 be called at all - only the destructor. The destructor may be
7818 NULL if destructor is not needed.
7820 All this applies for client library code as well. Similar
7821 changes were made there as well for the pending commands.
7823 In the client, the application must now allocate the
7824 SilcClientCommandContext with the silc_client_command_alloc
7827 * Added reference counter to the SilcServerCommandContext. Added
7828 function silc_server_command_alloc and silc_server_command_dup
7831 Same type of functions added to the client library for the same
7834 * Removed the cmd_ident from IDListData away since it is now
7835 global for all connections. It is the command identifier used
7836 in command sending and with pending commands. The affected file
7839 * Added reference counter to the SilcSocketConnection objecet to
7840 indicate the usage count of the object. The object won't be
7841 freed untill the reference counter hits zero. Currently only
7842 server uses this, and client ignores it. The client must be
7843 set to use this too later. The affected files are
7844 lib/silccore/silcsockconn.[ch]. Added also the function
7845 silc_socket_dup to increase the reference counter.
7847 This was mainly added because it is possible that the socket
7848 is removed underneath of pending command or other async
7849 operation. Now it won't be free'd and proper DISCONNECTING
7850 flags, etc. can be set to avoid sending data to connection that
7851 is not valid anymore.
7853 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7854 the connection. After that it sets SILC_SET_DISCONNECTED.
7855 It is, however, possible that the socket data is not still freed.
7856 The silc_server_packet_process now checks that data is not
7857 read or written to connection that is DISCONNECTED. The socket
7858 get's freed when the reference counter hits zero.
7860 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7862 * Changed the client operation API: channel_message operation's
7863 `sender' is now the client entry of the sender, not the nickname
7864 and the `channel' is the channel entry, not the channel name.
7866 In the private_message operation the `sender' is now also the
7867 client entry of the sender not the nickname.
7869 Affected file is lib/silcclient/ops.h and all applications
7870 using the client operations.
7872 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7874 * Moved the calling of ops->connect() from connect_to_server_final
7875 into receive_new_id functin since that is the point when the
7876 client is actually allowed to send traffic to network. The
7877 affected file is lib/silcclient/client.c.
7879 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7881 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7882 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7883 (if needs broadcasting) instead of broadcasting the packets one
7884 by one which would make a burst in the network traffic.
7886 * Added `broadcast' argument to the functions in silcd/server.[ch]
7887 silc_server_create_new_channel[_with_id] to indicate whether
7888 to send New Channel packet to primary router.
7890 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7892 * Added new function into the silcd/server.[ch] files:
7893 silc_server_create_new_channel_with_id to create new channel with
7894 already existing Channel ID.
7896 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7897 lib/silccore/silcpacket.h. This packet is used t send list of
7898 Set Mode payloads inside one packet. Server uses this to set
7899 the modes for the channels and clients on those channels, that it
7900 announced to the router when it connected to it. The protocol
7901 specification has been updated accordingly.
7903 * The silc_server_new_channel did not handle the packet coming
7904 from normal server as it normally does not send that. However,
7905 when it announces its channels it does send it. Implemented
7906 the support for that.
7908 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7909 into the file lib/silccore/id.h.
7911 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7913 * Fixed memory leaks in the functions silc_idlist_del_client,
7914 silc_idlist_del_channel and silc_idlist_del_server in the file
7915 silcd/idlist.c. All of those leaked like a sieve.
7917 * Fixed some small memory leaks in the client's function
7918 silc_client_notify_by_server.
7920 * Added functions into silcd/server.c: silc_server_announce_clients,
7921 silc_server_announce_channels and silc_server_announce_server.
7922 These functions are used by normal and router server to announce
7923 to its primary router about clients, channels and servers (when
7924 router) that we own. This is done after we've connected to the
7927 These functions effectively implements the following packet types:
7928 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7929 and SILC_PACKET_NEW_ID_LIST.
7931 * Added new functions into the silcd/packet_receive.[ch]:
7932 silc_server_new_id_list, silc_server_new_channel_list and
7933 silc_server_new_channel_user_list to handle the incoming
7934 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7936 * Added support of changing Channel ID in the function
7937 silc_server_replace_id. If the server that announces a channel
7938 to the router already exists in the router (with same name but
7939 with different Channel ID), router is responsible to send
7940 Replace ID packet to the server and force the server to change
7941 the Channel ID to the one router has.
7943 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7944 client that the Channel ID has been changed by the router. The
7945 normal server sends this to the client. Client must start using
7946 the new Channel ID as the channel's ID.
7948 Implemented handling of this new type into lib/silcclient/client.c
7949 into the function silc_client_notify_by_server.
7951 * Added new function silc_idlist_replace_channel_id into the files
7952 silcd/idlist.[ch] to replace the Channel ID.
7954 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7956 * Call silc_server_command_identify_check always when processing
7957 the IDENTIFY command in silcd/command.c
7959 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7961 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7962 send keepalive packets. The packet can be sent by clients,
7963 servers and routers.
7965 Added function silc_socket_set_heartbeat into the file
7966 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7967 If not set, the heartbeat is not performed. The actual
7968 heartbeat is implemented in the low level socket connection
7969 library. However, application is responsible of actually
7972 Added silc_server_send_heartbeat to send the actual heartbeat
7973 packet into silcd/packet_send.[ch]. Server now performs
7974 keepalive with all connections.
7976 * Added silc_task_get_first function into lib/silcutil/silctask.c
7977 to return the timeout task with shortest timeout. There was a bug
7978 in task unregistration that caused problems. TODO has been
7979 updated to include that task system must be rewritten.
7981 * The client library will now resolve the client information when
7982 receiving JOIN notify from server for client that we know but
7983 have incomplete information.
7985 * Rewrote parts of silc_server_remove_from_channels and
7986 silc_server_remove_from_one_channel as they did not remove the
7987 channel in some circumstances even though they should've.
7989 * Encryption problem encountered in server:
7991 The LEAVE command used to send the Channel Key packet to the
7992 router immediately after generating it. However, the code
7993 had earlier sent Remove Channel user packet but not immediately,
7994 ie. it was put to queue. The order of packets in the router
7995 was that Channel Key packet was first and Remove Channel User
7996 packet was second, even though they were encrypted in the
7997 reverse order. For this reason, MAC check failed. Now, this
7998 is fixed by not sending the Channel Key packet immediately but
7999 putting it to queue. However, this is more fundamental problem:
8000 packets that are in queue should actually not be encrypted
8001 because packets that are sent immediately gets encrypted
8002 actually with wrong IV (and thus MAC check fails). So, packets
8003 that are in queue should be encrypted when they are sent to
8004 the wire and not when they put to the queue.
8006 However, the problem is that the current system has not been
8007 designed to work that way. Instead, the packet is encrypted
8008 as soon as possible and left to the queue. The queue is then
8009 just purged into wire. There won't be any fixes for this
8010 any time soon. So, the current semantic for packet sending
8013 o If you send packet to remote host and do not force the send
8014 (the packet will be in queue) then all subsequent packets to the
8015 same remote host must also be put to the queue. Only after the
8016 queue has been purged is it safe again to force the packet
8019 o If you send all packets immediately then it safe to send
8020 any of subsequent packets through the queue, however, after
8021 the first packet is put to queue then any subsequent packets
8022 must also be put to the queue.
8024 Follow these rules and everything works fine.
8026 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8028 * Added new function silc_server_remove_clients_by_server to
8029 remove all client entries from ID list when the server connection
8030 is lost. In this case it is also important to invalidate all
8031 client entires as they hold the invalid server entry. This
8032 fixes fatal bug when server has lost connection and will reconnect
8035 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8037 * Made some sanity checks to silc_server_daemonise like to check
8038 whether the requested user and group actually exists.
8040 * Added sanity check to SKE's silc_ske_responder_finish to check
8041 that the public and private key actually is valid.
8043 * Invalidate the client's nickname when receiving Replace ID
8044 packet and the Client ID is being replaced. This means that the
8045 server will query the nickname if someone needs it (client)
8048 * Sort the ID Cache in client library when the ID Cache data
8049 has changed (needs sorting).
8051 * Do not allow for SILC client to create several connections to
8052 several servers. The client does not support windows right now
8053 and generating multiple connections causes weird behaviour.
8055 Irssi-silc client does support windows and can handle several
8056 connections without problems, see: www.irssi.org and SILC plugin.
8058 * Fixed some places where client was added to the IDList. The
8059 rule of thumb is following (in order to get everything right):
8060 If the client is directly connected local client then the
8061 `connection' argument must be set and `router' argument must be
8062 NULL to silc_idlist_add_client function. If the client is not
8063 directly connected client then the `router' argument must
8064 bet set and the `connection' argument must be NULL to the
8065 silc_idlist_add_client function.
8067 * The funtion silc_server_packet_send_local_channel actually did
8068 not check whether the client was locally connected or not. It
8069 does that now. Fixed a bug related to LEAVE command.
8071 * Fixed Remove Channel User payload parsing bug in server's
8072 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
8074 * The server's silc_server_save_channel_key now checks also the
8075 global ID list for the channel as it might not be in the local
8076 list. Fixed a bug related to LEAVE command.
8078 * Is this the end of the [<unknown>] buglet that has been lurking
8079 around for a long time? A little for loop fix in server's
8080 silc_server_command_whois_parse that is used by both IDENTIFY
8081 and WHOIS command. At least, this was a clear bug and a cause
8082 of one type of [<unknown>] buglet.
8084 * WHOIS and IDENTIFY commands call the function
8085 silc_server_command_[whois/identify]_check function even if
8086 we are not router server.
8088 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8090 * Added --with-gmp configuration option. If set the GMP
8091 is always compiled in the SILC source tree. If not set then
8092 it is checked whether the system has the GMP3 installed. If
8093 it has then the GMP won't be compiled (the system's headers
8094 and library is used), if it doesn't have it then the GMP is
8095 compiled in the SILC source tree.
8097 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8099 * Changed RSA private exponent generation to what PKCS #1
8100 suggests. We try to find the smallest possible d by doing
8101 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
8102 not security fix but optimization.
8104 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8106 * Added new config entry [Identity] to fork the server and run
8107 it as specific user and group. A patch from Bostik.
8109 * Imported Dotconf configuration library into lib/dotconf.
8110 This will be used to create the SILC configuration files later.
8111 It will appear in the distsribution after this commit.
8113 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8115 * A big code auditing weekend happening. Auditing code for
8116 obvious mistakes, bugs and errors. Also, removing any code
8119 Removed files for being obsolete:
8121 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
8122 inline in the file lib/silcutil/silcbuffer.h)
8124 o lib/silcutil/silcbufutil.c (the header has inline versions)
8126 Changed code to fix possible error conditions:
8128 o The buffer formatting routines now check that the destination
8129 buffer really has enough space to add the data. This applies for
8130 both buffer formatting and unformatting
8131 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
8132 unformatting was changed to accomodate following rules:
8133 XXX_*STRING_ALLOC will allocate space for the data into the pointer
8134 sent to the function while XXX_*STRING will not allocate or copy
8135 the data into the buffer. Instead it sets the pointer from the
8136 buffer into the pointer sent as argument (XXX_*STRING used to
8137 require that the pointer must be allocated already). This change
8138 makes this whole thing a bit more consistent and more optimized
8139 (note that the data returned in the unformatting with XXX_*STRING
8140 must not be freed now). The routines return now -1 on error.
8142 o Tried to find all code that use buffer_format and buffer_unformat
8143 and added return value checking to prevent formatting and
8144 especially unformatting errors and possible subsequent fatal
8147 o Changed ske->x and ske->KEY to mallocated pointers in
8148 lib/silcske/silcske.h. Fixed possible data and memory leak.
8150 o Added return value checking to all *_parse* functions. Fixed
8151 many memory leaks as well.
8153 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
8154 so that buffer overflows would not happen. All code now also
8155 checks the return value as it can fail.
8157 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8159 * Added reconnection support to server if the normal server looses
8160 its connection to the router (for example if router is rebooted).
8161 The server performs normal reconnection strategy implemented
8162 to the server. Affected file silcd/server.c.
8164 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8166 * Added new packet type SILC_PACKET_SET_MODE that is used to
8167 distribute the information about changed modes (for clients,
8168 channels and clients channel modes) to all routers in the
8169 network. Updated the protocol specification accordingly.
8171 Added functions into silcd/packet_send.c and
8172 silcd/packet_receive.c: silc_server_send_set_mode,
8173 silc_server_set_mode.
8175 Added new files silcmode.[ch] into lib/silccore that implements
8176 the encoding and decoding of Set Mode Payload. Added new type
8177 SilcSetModePayload. Moved the definitions of different modes
8178 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
8180 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8182 * Oops, a little mistake in server's connection authentication
8183 protocol. The protocol is not ended with FAILURE but with
8184 SUCCESS if the authentication is Ok. :) Affected file is
8187 * Implemented NICK_CHANGE notify handling in server in the file
8188 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
8189 the local clients on the channel. After the changing nickname
8190 in router environment snhould work and the [<unknown>] nickname
8191 should appear no more.
8193 The silc_server_replace_id function that receives the Replace ID
8194 payload now sends the NICK_CHANGE notify type also in the file
8195 silcd/packet_receive.c
8197 * Changed WHOIS and IDENTIFY command to support the maximum amount
8198 of arguments defined in protocol specs (3328 arguments). This
8199 fixed a bug that caused problems when there were more than three
8202 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8204 * Added extra parameter, command identifier, to the
8205 silc_client_send_command so that explicit command identifier
8208 Changed that ID list routines uses specific command identifier
8209 when sending WHOIS/IDENTIFY requests to the server so that they
8210 can be identified when the reply comes back.
8212 Affected files lib/silcclient/command.[ch],
8213 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
8215 * Added `sender' argument to silc_server_packet_send_to_channel
8216 to indicaet the sender who originally sent the packet to us
8217 that we are now re-sending. Ignored if NULL. Affected file
8218 silcd/packet_send.[ch].
8220 * Added some server statistics support in silcd/server_internal.h
8221 SilcServerStatistics structure and around the server code. Also
8222 send some nice statistics information when client is connecting
8225 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8227 * Fixed channel ID decoding in server's JOIN command reply in
8228 silcd/command_reply.c
8230 * Fixed braodcasting of replace ID payload to not to send it if
8231 we are standalone server in silcd/packet_receive.c.
8233 * Fixed all channel message sending routines to not to send
8234 packets to clients that has router set, since they are routed
8235 separately in the same function earlier. Affects file
8236 silcd/packet_send.c and all channel packet sending functions.
8238 * In USERS reply, res_argv[i] are not allocated, the table
8239 is allocated. Thus changed that free the table, not its
8242 * In server's whois_check and identify_check if the client is
8243 locally connected do not send any WHOIS commands - they are not
8246 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8248 * Fixed some minor bugs in client when sending WHOIS command. The
8249 arguments was in wrong order.
8251 * Removed statis function add_to_channel from server in
8252 silcd/command.c that was previously used with the joining but
8255 * Tested USERS command in router environment successfully with two
8256 routers, two servers and two clients.
8258 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8260 * Reorganized the USERS command and command reply in client library
8261 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
8262 When the command is given by user we register a pending command
8263 callback that will reprocess the command after the reply has been
8264 received from the server. When reprocessing the packet we then
8265 display the information. Thus, the USERS information is displayed
8266 now in the command callback instead of in the command reply
8267 callback. The processing of the command is same as previously
8268 when server has sent the command reply in the JOINing process.
8270 * Added to USERS command in silcd/command_reply.c to join the client,
8271 we didn't use to know about, to the channel after we've created
8272 a client entry for it. Also, for clienet we did know already still
8273 check whether it is on the channel or not and add it if not.
8275 * Removed silc_server_command_join_notify as the function and its
8278 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8280 * Changed the client's pending command handling to the same as the
8281 server's pending command handling. It is also now possible to
8282 execute command reply functions from other command reply
8283 function as the function callbacks for commands and command
8284 replies are one and same. The pending commands are not static
8285 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8286 in client connection context. Thus, pending commands are server
8287 connection specific as it is convenient.
8289 Changed the function silc_client_command_pending and
8290 silc_client_command_pending_del and added new function
8291 silc_client_command_pending_check. Removed the
8292 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8295 * Added cmd_ident, current command identifier, to the client
8296 connection context in lib/silcclient/client.h to keep track on
8297 command identifiers used in command sending. Client's command reply
8298 function handling now supports the mandatory command identifiers.
8300 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8301 funtions in client to fully support pending command callbacks.
8303 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8304 as one of the arguments to the application in the command reply
8307 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8308 before first releasing SILC but came back. Now it is removed again
8309 and should come back nomore. The FORWARDED flag was used only
8310 by the JOINing procedure by forwarding the command packet to router.
8311 Now, the JOINing procedure has been changed to more generic (due
8312 to various router environment issues) and FORWARDED is not needed
8313 anymore for anything. The protocol specification is yet to be
8316 Now, removed silc_server_packet_forward from server and the flag
8317 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8319 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8321 * Renamed NAMES command to USERS command. The NAMES was named that
8322 due to historical reasons. Now it is renamed. Also, rewrote
8323 parts of the USERS command. The nickname list is not sent anymore
8324 by the server. Only Client ID and mode lists are sent in the USERS
8325 command. Changed this also to the protocol specification.
8327 The client now resolves the names and stuff after it receives
8328 the USERS list from the server when joining to the channel.
8330 * WHOIS and IDENTIFY commands has been changed to support multiple
8331 Client ID's per command. One can now search for multiple users
8332 in the network by sending only one WHOIS or IDENTIFY command.
8333 Changed the code and the protocol specifications.
8335 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8336 uses silc_server_command_whois_parse to parse the request. */
8338 * If normal server, do not parse the WHOIS and IDENTIFY requests
8339 before sending it to the router. Saves some time.
8341 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8343 * Fixed JOIN command on client library. Wrong number of arguments
8344 used to crash the client.
8346 * Added silc_server_channel_has_global function to check whether
8347 channel has global users or not.
8349 * Added silc_server_channel_has_local function to check whether channel
8350 has locally connected clients on the channel.
8352 * The silc_server_remove_from_one_channel now checks whether the
8353 channel has global users or not after given client was removed from
8354 the channel. It also checks whether the channel has local clients
8355 on the channel anymore. If it does not have then the channel entry
8356 is removed as it is not needed anymore.
8358 * The silc_server_notify now checks on JOIN notify whether the joining
8359 client is one of locally connected or global. If it is global then
8360 the channel has now global users on the channel and that is marked
8361 to the channel entry. Also, it now saves the global client to
8362 global list who is joining and JOINs it to the channel. This is
8363 for normal server, that is.
8365 Changed silc_server_send_notify_on_channel,
8366 silc_server_packet_relay_to_channel and
8367 silc_server_packet_send_to_channel check if we are normal server
8368 and client has router set (ie. global client) do not send the
8369 message to that client, as it is already routed to our router.
8371 * Implemented LEAVE notify type handling in silc_server_notify
8374 * Tested LEAVE command in router environment successfully. Tested
8375 with two routers, two servers and two clients.
8379 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8381 * Implemented SIGNOFF notify type handling in silc_server_notify
8384 * silc_server_remove_id now removes the client entry from all channels
8385 it has joined and thusly sends SIGNOFF notify type.
8387 * Rewrote the NAMES list generation in server by removing two excess
8388 loops. The lists are created now inside one loop.
8390 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8392 * silc_server_remove_channel_user checks now also global list
8393 for channel and client.
8395 * silc_server_new_channel_user checks now both local and global
8396 list for channel and client. Fixed a bug in client id decoding.
8397 Used to decode wrong buffer.
8399 * silc_server_channel_message checks now both local and global
8400 list for channel entry.
8402 * Tested channel joining (hence JOIN) in router environment
8403 successfully. Tested with two routers, two servers and two
8406 * Tested channel message sending in router environment successfully.
8408 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8410 * Added silc_server_save_channel_key into server.[ch] to save the
8411 received channel key in Channel Key payload processing. It is
8412 also used in JOIN command reply handling.
8414 Equivalent function silc_client_save_channel_key added into
8415 client.[ch] into client library.
8417 * Changed JOIN command reply to send information whether the channel
8418 was created or not (is existing already) and the channel key
8419 payload. Changed protocol specs accordingly.
8421 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8422 the request was sent by ID and not by nickname. Crashed on
8425 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8427 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8428 now correctly save the received data.
8430 * silc_server_free_sock_user_data now notifies routers in the
8431 network about entities leaving the network.
8433 At the same time implemented functions silc_server_remove_id
8434 and silc_server_send_remove_id to receive and send REMOVE_ID
8435 packets. The packet is used to notify routers in the network
8436 about leaving entities. The ID removed will become invalid in
8439 * Added function silc_idlist_del_server into server. Removes and
8440 free's server entry from ID list.
8442 * silc_server_private_message function now checks, if we are router,
8443 that the destination ID really is valid ID, naturally.
8445 * In router when NEW_ID packet is received (for new client) the
8446 hash of the Client ID is saved in the ID Cache but the
8447 client->nickname is set to NULL, instead of putting the hash
8450 IDENTIFY command now also checks that client->nickname must be
8451 valid. If it is not if will request the data from the server who
8452 owns the client. Added new function
8453 silc_server_command_identify_check.
8455 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8456 to set the command to already allocated Command Payload.
8458 * Tested private message sending in router environment with two
8459 routers, two servers and two clients. Fixed minor bugs and now
8462 * Fixed segfault from client's NAMES command. Used to crash if
8465 * Forwarded packets must not be routed even if it is not destined
8466 to the receiver. Changed server code comply with this.
8468 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8470 * Added `require_reverse_mapping' boolean value to ServerParams
8471 structure. If TRUE (not default) the server will require that
8472 the connecting host has fully qualified domain name.
8474 If the reverse mapping is not required and hostname could not be
8475 found the IP address is used as hostname.
8477 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8479 * Implemented version string checking to both client and server.
8480 The check is incomplete currently due to the abnormal version
8481 strings used in development version of SILC.
8483 * Changed all command functions in server to use the new
8486 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8488 * Changed char *data to unsigned char *data in ID Cache system to
8489 support binary data as ID Cache data. Changed code to support
8490 binary data in lib/silccore/idcache.c.
8492 * Renamed silc_server_packet_relay_command_reply to
8493 silc_server_command_reply as it is normal packet receiving
8494 function. Rewrote the function to accept command replys for
8495 servers and not only for clients.
8497 * Mark remote router always as registered server if we are connecting
8498 to it. Otherwise, commands sent by the router to us are ignored.
8500 * All ID List find routines now returns the ID Cache Entry pointer
8501 as well if requested.
8503 * WHOIS command works now in router environment, tested with two
8504 routers, two servers and two clients.
8506 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8507 in router environment (as it is almost equivalent to WHOIS) but
8508 hasn't been tested thoroughly. Added new functions:
8510 silc_server_command_identify_parse
8511 silc_server_command_identify_send_reply
8512 silc_server_command_identify_from_client
8513 silc_server_command_identify_from_server
8515 * Disabled route cache adding because adding two different ID's with
8516 same IP replaces the old cache entry thus giving wrong route.
8517 The entry->router->connection is always the fastest route anyway
8518 so route cache may not be needed. Of course, new routes maybe
8519 established after receiving the ID when the entry->router->connection
8520 might not be anymore the most optimal.
8522 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8524 * Add route cache for received ID for fast routing.
8526 * Added silc_server_packet_route to route received packet on router
8527 that is not destined to us.
8529 * Renamed silc_server_get_route to silc_server_route_get.
8531 * Added id_string and id_string_len fields into SilcServer to
8532 include encoded ServerID for fast comparing without excess
8533 encoding of the ID's.
8535 * Cleaned up WHOIS command on server side. Added following static
8538 silc_server_command_whois_parse
8539 silc_server_command_whois_check
8540 silc_server_command_whois_send_reply
8541 silc_server_command_whois_from_client
8542 silc_server_command_whois_from_server
8544 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8545 arguments in command replies. All command functions should be
8546 updated to use this macro.
8548 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8550 * Minor typo fixes on command reply handling on server.
8552 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8554 * Added silc_server_command_add_to_channel internal routine to add
8555 the client to the channel after router has created the channel and
8556 sent command reply to the server.
8558 * Added generic silc_server_send_command to send any command from
8561 * Use static buffer with ID rendering instead of duplicating data.
8563 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8565 * Fixed a channel user mode bug when joining to a channel server gave
8566 everybody channel founder rights, oops.
8568 * We mark ourselves as the router of the incoming server connection
8569 if we are router ourselves. This way we can check in some packet
8570 sending functions whether it is locally connected server. For
8571 incoming router connections we put NULL.
8573 * For router sending packets locally means now always sending the
8574 packet cell wide; to local clients and local servers. For normal
8575 server sending packet locally means sending it to only local
8578 * Fixed the JOIN command to really work in router environment. If the
8579 channel is created it is always created by the router. Router is
8580 also responsible of making the initial joining to the channel,
8581 sending JOIN notify to the sending server and distributing
8582 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8583 does not exist server doesn't do anything else but forward the
8584 command to the router which performs everything.
8586 * Added silc_server_send_channel_key function to send the Channel Key
8589 * Added silc_server_create_channel_key to create new channel key. The
8590 channel key is now re-generated everytime someone joins or leaves
8591 a channel, as protocol dictates. Note: channel->key_len is the
8594 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8596 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8597 packet_receive.[ch] to separate packet sending and receiving
8598 routines. The server.[ch] now includes everything else including
8599 actual packet processing (writing and reading data) and other
8602 Renamed silc_server_private_message_send_internal to
8603 silc_server_send_private_message. The routine is still though
8604 used only to relay private messages as server does not send
8605 private messages itself.
8607 Renamed silc_server_new_channel to silc_server_create_new_channel
8608 and added new function sicl_server_new_channel that handles the
8609 incoming New Channel packet. Added also new sending function
8610 silc_server_send_new_channel to send New Channel Payload.
8612 * Added new function silc_server_notify to process incoming notify
8613 packet to the server/router. Server may then relay the notify
8614 to clients if needed.
8616 * Added new function silc_server_new_channel_user to process incoming
8617 New Channel User packet. Router will redistribute the packet and
8618 send JOIN notify to its local clients and locally connected servers
8619 if needed. Normal server will send JOIN notify to its local client
8620 on same channel when received this packet. Added also corresponding
8621 sending function silc_server_send_new_channel_user to sent the
8624 * Added boolean route argument to send_notif_to_channel and
8625 packet_send_to_channel functions to attempt to route the packet
8626 if it is TRUE and send only locally if it is FALSE.
8628 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8630 * silc_server_replace_id now broadcasts the received replace ID
8631 packet if it is not broadcast packet already. The router must
8632 broadcast to inform other routers about changed ID.
8634 * Added backpointer to server's router into SilcServer context in
8635 silcd/server_internal.h.
8637 * Fixed silc_server_packet_broadcast to send correct broadcast
8640 * The channel key is now distributed to the local client as soon
8641 as it is received from the router (in router environment) so that
8642 no other packet may be sent for the channel until client has
8645 * silc_server_remove_channel_user now broadcasts the received
8646 Remove Channel User packet if it is not broadcast packet already.
8647 The router must broadcast to inform other routers about removed
8650 * Added users field into SilcPacketContext that is a reference count
8651 of the context. One can increase the reference count by calling
8652 silc_packet_context_dup which is now changed to just increase the
8653 reference count instead of duplicating the data. The reference
8654 count is decresed by calling silc_packet_context_free that will
8655 free the data after the reference count hits zero.
8657 For now on the packet context and everything allocated into it
8658 (including the raw packet from network) must be freed by calling
8659 the new silc_packet_context_free function. Added also new function
8660 silc_packet_context_alloc that must be used now to allocate the
8661 context. This also means that if a routine is asynchronous from
8662 silc_[client/server]_packet_parse_type the packet context must
8663 be duplicated by calling silc_packet_context_dup. Otherwise it
8664 gets free'd after silc_[client/server]_packet_parse_type returns.
8665 Also, one must remember that if packet is duplicated then its
8666 reference count must be decresed by calling the free function as
8667 many times as it was duplicated.
8669 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8670 from both client and server.
8672 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8674 * Made joining to a channel working in router environment.
8676 * Cleaned up JOIN command on server side and create function
8677 silc_server_command_join_channel internal routine to make the
8680 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8682 * Changed silc_command_pending list to SilcDList. Also, added
8683 `ident' field to SilcServerCommandPending structure to identify
8684 the reply and to call correct callback.
8686 Added silc_server_command_pending_check function to replace the
8687 corresnponding macro. The silc_command_pending list is not
8690 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8691 to set identifier to previously allocated Command Payload. It
8692 is used to set identifier for command when resending Command
8695 * Added silc_command_payload_encode_payload to encode Command
8696 Payload buffer from SilcCommandPayload structure.
8698 * Added silc_argument_payload_encode_payload to encode Argument
8699 payload buffer from SilcArgumentPayload structure.
8701 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8703 * Changed WHOIS command to support router connection on server side.
8704 The whois request is always sent to router unless the server is
8705 standalone server. After server has received the reply from the
8706 router will it send the reply to the client.
8708 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8709 broadcast received broadcast packet. The function is used only
8710 by router. The broadcast packet is always sent to the router's
8713 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8714 render given ID to printable string, for log files for example.
8716 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8718 * Made basic router to router connections working. At least they
8719 can now connect to each other but nothing really works the way
8720 they are supposed - yet.
8722 * Added new initiator token to RouterConnection configuration
8723 file in silcd/serverconfig.[ch]. It is used to tell whether we
8724 are the initiator to the remote router or whether we'll expect
8725 the other end to connect.
8727 * Moved registering of listener task to silc_server_init, hence
8728 the server starts listenning as soon as it is run, even if it
8729 does not have connections to other routers. Let's see how well
8732 * Changed default connection retry timeouts for more suitable in
8735 * Removed cipher and such arguments from silc_idlist_add_client
8736 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8737 Added new function silc_idlist_add_data to add the keys and stuff
8740 * Added SilcIDListData structure and added it to SilcClientEntry
8741 and SilcServerEntry as their first field in the structure. This
8742 way we can explicitly cast the ID entries to the SilcIDListData
8743 structure and get common data for the entries. In past, we had
8744 to first check what type of connection it is and then cast it to
8745 correct ID entry type. Now, we can directly cast the opaque
8746 pointer to the SilcIDListData (no matter what ID entry it actually
8747 is) and get the data needed.
8749 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8751 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8752 in some circumstances even if threre were timeout tasks, though not
8753 IO tasks, but tasks anyway. Now fixed.
8755 * Defined SilcServerConnection structure to hold connection specific
8756 stuff about directly connected servers and routers. The definition
8757 is currently in silcd/server_internal.h. I thought about having
8758 a bit more important role fro this struct but for now it is used
8759 only when connecting to other server (or router actually).
8761 * Added connecting retry support in server when connecting to
8762 router(s). The retry feature implement exponential backoff
8763 algorithm. Also, added SilcServerParams structure to hold default
8764 parameters for server. For now, it include these retry settings
8765 and are hard coded. After server is moded to be as Silc Server
8766 Library this structure will be more important.
8768 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8770 * Changed client librarys channel->clients table to SilcList and
8771 changed code accordingly.
8773 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8775 * Changed client's channel table to SilcList and changed code
8776 accordingly. Also changed SilcChannelClientEntry to include back-
8777 pointer to the channel so that client entry can use that structure
8778 as list as well and we have fast cross-reference to the channel.
8779 This change dramatically decreased the complexity of channel
8780 handling with client entry and vice versa (removed one extra
8781 loop when searching for channel entry from many functions).
8783 * Changed server->sim from table to SilcDList and changed code
8786 * NAMES command can now be used from user interface. It will show
8787 the user list on the channel, neatly.
8789 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8790 Code now saves realname of the user if it becomes available.
8792 * Renamed configure.in to configure.in.pre and made ./prepare
8793 script to automatically add correct version string to
8794 configure.in which it creates from configure.in.pre.
8796 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8798 * NAMES command reply now shows users mode with the nickname when
8801 * Moved silc_client_ch[u]mode[_char] functions from
8802 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8803 place sucks, they are utility functions and should be in some
8806 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8808 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8811 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8815 * Added TRQ (efficient deque and list library) into lib/trq. This is
8816 a very good list library that is currently used in the SILC. Defined
8817 SilcList API over the library because I didn't like the API very
8818 much. See lib/trq/silclist.h for the API and examples of how to
8819 use the API. Fixed various places in the code to use the new
8820 SilcList API. The SilcList is meant for lists that has a structure
8821 already defined as a list. It is not suitable to add just some
8822 context to the list (in TRQ, the context is the list actually).
8824 So, I defined SilcDList that can be used for the purpose where
8825 predefined list structure does not exit. This can be used as
8826 such list. Now some context just can be added to the SilcDList.
8827 Currently this list is not used in the SILC just yet, though there
8828 are a lot places where this can replace dynamically allocated
8829 tables and I will fix these places, later, to use SilcDList.
8830 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8831 and use TRQ internally).
8833 Also fixed some annoying warning messages that the original TRQ
8834 code generated. Also minor changes to TRQ's Makefile.in.
8836 * Added support for querying by Client ID to both WHOIS and
8837 IDENTIFY commands into server, as required by the protocol.
8839 * Removed method function pointers from SilcBuffer structure. They
8840 weren't used to anything and just increased the context size for
8841 no good reason. This change also made silc_buffer_alloc and
8842 silc_buffer_free functions inline functions.
8844 * Disabled command flooding detection support until it's fixed so
8845 that it accepts commands in but does not execute them more than once
8848 * Added silc_net_localhost(), to return local hostname, into
8849 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8850 that must be initialized before calling silc_client_init.
8852 * Added new function: silc_server_send_notify_on_channels to send
8853 notify messages to all channels client has joined. It is assured
8854 that the message is sent only once per client.
8856 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8857 lib/silcutil/silcutil.[ch] as silc_format function. The new
8858 function is generic and is used by server as well, not only by
8859 the logging routines.
8861 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8862 the provided version string was not acceptable. Added new function:
8863 silc_ske_check_version into lib/silcske/silcske.h. The function
8864 must be implemented by the application (client or server) and it
8865 does not reside in the SKE library. The function checks the version
8866 string remote end sent.
8868 * Added back pointers (to opaque context and to SilcSocketConnection)
8869 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8871 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8872 duplicate packet context structure.
8874 * Changed `notify' client operation to send same arguments as client
8875 receives from server except for ID's. ID's are mapped to correct
8876 ID entry and that is returned. Also, if channel entry is not sent
8877 by server but the notify is for channel the channel entry is sent
8878 to application (otherwise application doesn't know that it is for
8879 channel (library gets it from packet's Destination ID)).
8881 * Added silc_client_remove_from_channels into client library to
8882 remove a client from all channels it has joined to. Used when
8883 received SIGNOFF notify from server. Added also new function
8884 silc_client_replace_from_channels to replace old ID entry with
8885 new ID entry on all channels. Used when received NICK_CHANGE
8888 * Fixed ID Cache list handling in silc_idlist_get_client in
8889 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8890 to get (or query) client by ID.
8892 * Updated TODO list.
8894 * Added connection authentication status message defined by the
8895 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8896 support for these into the code in client and server side.
8898 * Added generic function silc_client_send_command to send any command
8899 with variable argument list. Application should use this function
8900 to send commands if the command functions provided by the library
8901 does not suite for the application's user interface needs.
8903 * Added new `failure' client operation. Application is notified about
8904 received failure packet if client is executing a protocol. In this
8905 case the protocol's execution has failed.
8907 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8908 is required by the protocol.
8910 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8911 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8914 * Added status flag to SilcSKE object to indicate realtime status
8915 of the SKE protocol.
8917 * Application receives now exactly same command reply arguments as
8918 the library receives from server. However, if ID is received the
8919 corresponding ID entry is returned to the application (eg. Client
8920 ID is mapped to correct SilcClientEntry entry and that is returned).
8921 Changed command_reply client operation due to this change.
8923 * Changed all ID's in commands and in command replys as ID Payloads.
8924 Change affected both client and server side codes.
8926 All ID's sent in SILC network (with execption of ID's in SILC
8927 Packet header) are sent in ID Payload to support variable length
8930 * Server now notifies nick changes and notifies all clients on
8931 the channels about the new nickname (about the new Client ID,
8934 * Implemented CMODE command to change channel modes. Supports all
8935 channel modes defined by the protocol specs except ban and invite
8936 lists. (Also, private channel key mode is supported but support for
8937 setting private channel key in client is missing, thus, this mode
8938 has no effect on client side (except that server requires that the
8939 client uses private channel key and normal channel traffic does not
8942 Also, invite mode works per se, but INVITE command does not work
8943 yet correctly, so you can set channel as invite only channel but
8944 inviting clients to the channel does not work (it is yet to be
8945 thought what's the best way to do it).
8947 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8948 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8949 Implemented CUMODE command to change user's mode on the channel.
8950 Supports all modes defined by the protocol specs.
8952 * Added NAMES command reply to return users modes on the channel.
8954 * Removed unnecessary and slow ciphers from lib/silccrypt.
8956 * Set SO_KEEPALIVE option to connection sockets by default.
8958 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8960 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8961 redefined the Notify Payload into protocol specs.
8963 * Added silc_id_payload_parse_id to get ID directly from raw
8966 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8968 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8969 accept searching by Client ID as well.
8971 * Added support for LEAVE and SIGNOFF notify types in client library.
8973 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8974 to parse ID Payload from raw data.
8976 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8978 * Added flags parameter into silc_ske_assemble_security_properties
8979 function in lib/silcske/silcske.[ch].
8981 * Changed notify client operation to fit better for notify messages
8982 sent by server. The notify payload received from server is now
8983 passed to the application (after parsing it to SilcNotifyPayload).
8984 It is application's responsibility to retrieve the arguments
8985 from the payload and show the message the way it wants. The message
8986 sent by server is implementation specific.
8988 * Changed public keys to comply with the protocol specification.
8989 Old public keys are not supported anymore and are not compatible.
8991 * Removed nickname from Channel Payload as the latest draft removed
8992 it. The client must resolve the nickname from the NAMES command
8993 reply received when it joined the channel.
8995 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8997 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8999 * Fixed some errors in protocol specification drafts.
9001 * Created lib/silccore/silcnotify.c to implement Notify Payload
9002 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
9003 generic payloads described by protocol specifications. The file
9004 includes implementations for ID Payload and Argument Payload.
9006 * Changed Command Payload implementation to use the new Argument
9007 Payload. Changed command_xxxx_payload to command_payload_xxxx
9008 to comply with SILC coding conventions.
9010 * Added suppport for Argument Payload handling in Notify Payload
9011 implementation as protocol requires it. Added the new support
9012 into server and client lib as well.
9014 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9016 * Added support for multiple nicknames on same channel. [n] is
9017 added locally to the nickname if there are more than one same
9018 nicknames on the channel.
9020 * Server now sends all nicknames that matched WHOIS request.
9021 Client also shows the list received from server.
9023 * Added TOPIC command to client side. User can now set and show
9024 current topic on channel.
9026 * Added MOTD command to client and server. Also, server sends the
9027 motd when client connects to the server.
9029 * Changed version strings to comply ISO 8601.
9031 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9033 * Fixed protocol error handling in client library. It should now
9034 cope even if the SKE fails for some reason.
9036 * Made new protocol specification drafts for submitting to IETF.
9038 * Implemented TOPIC command to server in silcd/command.c.
9040 * Added two new notify types into lib/silccore/silcnotify.h:
9041 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
9042 notify nickname change and topic setting/change on a channel.
9044 * API change of command_reply operation in client library. The
9045 application gets now the status type received from server as well.
9047 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9049 * Removed the function just added to lib/silcutil/silcschedule.[ch].
9051 * Cras fixed and optimized the packet handling even further and
9052 it should work now. Minor change to the prototype of function
9053 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
9055 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9057 * Added new function into lib/silcutil/silcschedule.[ch]:
9058 silc_schedule_with_fd to select() a specified fd. The function
9059 returns after timeout expires or data arrives or goes. The
9060 function is used by packet routines to wait that all data is
9061 received from network.
9063 * Fixed data reading from network in lib/silccore/silcpacket.c.
9064 The code now assures that all data is read from the fd and then
9065 continues packet processing. This was a bug fix since the code
9066 used to drop some data in some circumstances.
9068 * Added new function into lib/silcclient/client.[ch]:
9069 silc_client_start_key_exchange to start key exchange after
9070 connection has been established to server. The code internally
9071 now uses this funtion but its main purpose was to provide it
9072 for applications that perform their own connecting. After
9073 application has created a connection it merely calls this
9074 function to start the key exchange between client and server.
9075 The library takes care of everything else after that.
9077 Updated also lib/silcclient/README to explain the usage of
9080 * Do not send to application information that connection has
9081 been established. Application gets notified it by connect
9084 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9086 * Applied cras's patch to add silc_schedule_one function. The
9087 function runs scheduler once and returns.
9089 * Fixed the scheduler after cras messed it up. The timeout
9090 handling works now as it's supposed to work.
9092 * Added into lib/silccore/ silcnotify.h to include notify
9093 message types support. Changed silc_server_send_notify*
9094 functions, in server.[ch], to support those new notify types.
9095 Added the support for the notify types into client library,
9096 as well. Added new notify client operation into ops.h in
9099 * Changed silc_server_packet_send_to_channel to send normal
9100 packets instead of just channel message packets. The function
9101 is now used to send the notify packets to channels. It is not
9102 used to send channel message packets anymore, as server never
9105 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
9106 va_arg()s as it seems to require it nowadays. I guess, if SILC
9107 is compiled with older va_arg() the new code should work anyway.
9109 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9111 * Splitted core library. Core library (lib/silccore) includes
9112 now only SILC protocol specific core (and common) components.
9113 Created new utility library (lib/silcutil) that includes more
9114 generic purpose stuff. The stuff for util library was taken
9115 from the old core library. This was minor and easy split.
9117 * Created SILC Client Library (lib/silcclient) that includes
9118 implementation of the SILC client without user interface. This
9119 was major move from silc/ directory. The code has been changed
9120 so that it is transparent towards the user interface. The
9121 silc/ directory includes now the same user interface as before
9122 and it uses the new client library. Read lib/silcclient/README.
9123 Basicly, the client library performs everything else related
9124 to SILC except user interface handling. Also, configuration
9125 files are considered to be part of user interface and library
9126 does not handle them.
9128 This change also changed a lot of structures, function naming etc.
9129 Most important change was that SilcClientWindow object was
9130 renamed to SilcClientConnection in the client library. Created
9131 also new file lib/silcclient/ops.h. Also added new files
9132 silc/local_command.[ch] and silc/client_ops.[ch].
9134 All these changes were made to make it easier for user interface
9135 designers to create what ever user interface for the SILC client
9138 It is also expected that the server will be moved to lib
9139 directory as well and SILC Server Library will be created;
9140 sometimes in the future.
9142 * Removed Local commands from lib/silccore/silccommand.h as
9143 they are application specific and new client library does not
9144 handle any of those anymore.
9146 * Several functions moved to lib/silcutil/silcutilc.[ch] from
9147 old client implementation in silc/.
9149 * Added support for callback functions in SILC_LOG_* macros.
9150 Application can now set its own callbacks that will be called
9151 instead of using the default functions that will always print
9152 the debug messages to stderr (or stdout). Also, debugging can
9153 now be disabled by setting silc_debug to FALSE and re-enabled by
9154 setting it to TRUE. Note, that logging will still work even
9155 if debugging is disabled.
9157 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
9158 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
9159 silc_log_reset_debug_callbacks.
9161 * To enable debugging in silc client one must give now -d
9162 option on command line.
9164 * Changed silc_schedule_init to automatically allocate task queues
9165 if they are not allocated before calling it.
9167 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9169 * Added GMP 3.1 into math library.
9171 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9173 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
9174 a channel in SILC network. The packet is used by servers and
9175 routers to notify other routers that user has left a channel.
9176 This little feature was missing until now. Added the feature
9177 to protocol specification as well.
9179 Added functions: silc_server_send_remove_channel_user and
9180 silc_server_remove_channel_user into server.[ch].
9182 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
9183 lib/silccore/silcpacket.h. However, they are not implemented
9186 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9188 * Fixed joining to a channel and sending channel messages
9189 between server and router. The channel message sending should
9190 now work inside a cell.
9192 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9194 * Fixed the private message sending between server and router.
9195 The private message sending should now work inside a cell.
9197 * Added silc_server_replace_id into server.[ch] to replace
9198 existing ID in the SILC network.
9200 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
9201 and silc_idlist_replace_server_id into idlist.[ch] in server.
9203 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9205 * Fixed the server to server connections. Server can again now
9206 connect to router. Router to router connections probably does
9209 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9211 * Added dynamic protocol registering support. Now protocols can
9212 registered and unregistered on the fly. Patch by cras.
9214 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9216 * Added lib/contrib directory to hold routines that some platforms
9217 don't have but are needed by SILC.
9219 * Added getopt.c, getopt1.c and getopt.h from GNU C library
9220 into lin/contrib to provide getopt() and getopt_long() for
9221 those who don't have it.
9223 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9225 * Added AWAY command to client. When away message is set and
9226 client receives a private message packet the client automatically
9227 replies to the sender with the away message.
9229 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
9230 bug seemed to be the cause of recent problems when compiling
9233 * Added version detection support to SKE protocol specification
9234 and added the new changes to the SKE implementation as well.
9235 There were other minor changes in the SKE protocol as well.
9237 Many changes in lib/silcske/silcske.[ch] and in
9238 lib/silcske/payload.[ch].
9240 * Added ^U functionality, clear input line. Patch from cras.
9242 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9244 * Mainly small bugfixes on core library. Fixed some debugging
9245 logging and buffer overflow in silclog.c.
9247 * Updated config.sub and config.guess on the distribution tree.
9249 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9251 * Added command lagging support in server. Client may execute
9252 commands now only once in two seconds.
9254 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9256 * Optimized packet reception. MAC computation and checking is now
9257 also more optimized. A lot previously duplicated code is now
9258 used as generic by both client and server.
9260 * Fixed key pair generation in clientutil.c
9262 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9264 * Added into lib/silccore/silcbufutil.[ch] new function;
9265 silc_buffer_realloc.
9267 * Moved generic packet sending/encryption functions to
9268 lib/silccore/silcpacket.[ch] from client and server. Some
9269 rewriting of the functions.
9271 * Moved all generic packet reception/decryption functions to
9272 lib/silccore/silcpacket.[ch] from client and server. The
9273 packet processing is now much cleaner in both client and server.
9274 These were major changes in both client and server.
9276 * Created many common functions in server to do packet sending.
9277 Previously code were duplicated a lot, this has been removed
9280 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9282 * Rewrote major parts of the ID cache system. Don't know
9283 whether it is better now or not but at least the API is more
9286 * Major rewrite on ID cache stuff on client because of the ID
9287 cache API changes. Added idlist.c to client.
9289 * Also major rewrite on ID cache stuff on server as well.
9290 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9291 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9292 in hand, instead they are all put into the ID cache system now.
9293 All server_idlist_* routines uses ID cache now instead of
9294 traversing its own lists (those lists does not exist anymore).
9295 SilcIDList though still exists. Also, SilcXXXEntry's are
9298 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9300 * Finally made the SKE implementation compliant to the protocol
9301 specification. All mp integers are now binary encoded as
9302 opposed being HEX encoded.
9304 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9307 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9308 functions: silc_[encode/decode]_pem. Also added function
9309 silc_encode_pem_file to PEM encode with newlines ('\n') for
9312 * SILC public keys are now encoded either PEM or binary. Same
9313 option is for private keys as well. By default private keys
9314 are binary encoded and public keys PEM encoded. Silly HEX
9315 encoding were removed.
9317 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9318 function to create fingerprints.
9320 * Fixed a bug in SHA1; does not change the original data anymore.
9322 * Partly implemented INFO command on client and server side.
9323 Fixed CLEAR command. Changes to SERVER command; show current
9324 server(s) when giving command without arguments. Added
9325 VERSION command to client.
9327 * Added check to server that unregistered connections cannot
9328 execute commands (unless it is specificly allowed).
9330 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9332 * Fixed screen refresh.
9334 * Fixed channel joining bug from client. On some circumstances
9335 client tried to join to a channel it had already joined.
9337 * Added public key verification process into client's protocol.c.
9338 The client now verifies the public key from user and saves
9339 it into ~./silc/serverkeys/ directory.
9341 Added into: clientutil.[ch]: silc_client_verify_server_key.
9343 * Changed SKE protocol's silc_ske_initiator_finish function
9344 to accept callback function that verifies the received public
9345 key. Removed old silc_ske_verify_public_key function.
9347 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9349 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9350 silc_pkcs_private_key[_data]_set.
9352 * Made the password and public authentication more cleaner in
9353 server's protocol.c.
9355 * Removed historic and obsolete protocol `channel_auth' from
9356 both client and server.
9358 * Removed wrong way of sending command status messages from
9359 server to client in server's command.c. The old way violated
9360 protocol specification.
9362 Changes to silccore/silccommand.[ch]: removed
9363 silc_command_encode_status_payload -> not needed anymore,
9364 changed silc_command_encode_payload_va to accept extra
9365 argument on variable argument list. The argument type must
9366 now be provided to the function. Also, added new function:
9367 silc_command_encode_reply_payload_va which is same as
9368 normal command_encode_payload_va except command status type
9369 is provided as extra argument.
9371 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9373 * Added ~./silc directory handling. The directory includes the
9374 public and private keys for the client.
9376 Added silc_client_check_silc_dir, silc_client_create_identifier
9377 and silc_client_load_keys.
9379 * Implemented SILC protocol compliant public key. Added public
9380 and private key saving to and loading from files.
9382 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9383 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9384 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9385 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9386 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9388 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9389 silc_pkcs_load_[public/private]_key.
9391 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9393 * Added silc_server_get_route (route.[ch]) to get connection
9394 data for the fastest route for given ID.
9396 * Implemented INVITE command on client and server. The command
9397 were re-defined in the SILC Protocol Specification and the
9398 implementation now complies with the specification.
9400 * Implemented PING command on client and server.
9402 * Implemented NAMES command on client and server. The server side
9403 supports currently only normal server not router server yet.
9404 Some changes to NAMES definition in SILC protocol specification.
9406 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9408 * Implemented LEAVE command on client and server.
9410 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9411 again. This change was made to the protocol as well. Server
9412 should not violate the protocol specification anymore.
9414 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9416 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9417 was tested. SOCKS4 was not but should work anyway.
