1 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed fingerprint checking to check for entirely empty
4 fingerprint instead of two first bytes when determining
5 if it is set. Bug #18. Affected file silcd/command.c.
7 * Fixed duplicate PKCS name registering to not allow it.
8 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
10 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
12 * Conditionalize non-gcc compiler optimizations for various
13 platforms, enable those commented out. Cleanups.
14 Affected file lib/silcmath/mpi/configure.in
16 Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>
18 * silc_rng_exec_command() left zombie processes if command
19 didn't generate any output. Affected file
20 lib/silccrypt/silcrng.c
22 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
24 * Rewrote iconv checking, introduce --with-iconv for systems
25 which rely on libiconv. Check if iconv() provided by libc
26 is good enough, otherwise demand libiconv. Affected file
29 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
31 * Search for ldopen() also in libc. This enables SIM support
32 on *BSD systems. Based on patch from Alex Zepeda. Affected
35 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
37 * Don't call AM_CONDITIONAL conditonally for SILC_THREADS.
38 This fixes prepare on *BSD systems. Affected file
41 Sun Aug 4 15:55:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
43 * More fixed for not having purge timeout for global clients
44 that are on channel. Affected files silcd/command_reply.c
47 * Fixed the rekey protocol to work with backup router connections.
48 Rekey packets are now allowed on disabled connections as
49 well. Affected files silcd/packet_send.c and server.c.
51 * Do not switch to be as backup router when shutting down and
52 closing the primary connection. Affected file silcd/server.c.
54 * Fixed memory leaks in backup router deleting. Added
55 silc_server_backup_free to free all data during shutdown of
56 server. Affected files silcd/server_backup.[ch].
58 Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
60 * Do not process commands if the sock->user_data is NULL.
61 Affected file silcd/command.c.
63 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
65 * Fixed buffer overflow and security problems (loosing bits
66 in CFB encryption) in SILC RNG. Problems reported by
67 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
69 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
71 * Added yet more checks that client is not expired on global
72 list if it is on channels. Affected file is
73 silcd/command_reply.c.
75 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
77 * Merged c0ffee's MIME signal patch which adds support for
78 sending also MIME messages in Irssi SILC Client, and handling
79 received MIME messages in a signal (and perhaps doing something
80 to non-textual MIME messages).
82 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
84 * Fixed pending command deletion in server and client library
85 to check the whole list instead of breaking after first found.
86 The affected files are silcd/command.[ch] and
87 lib/silcclient/command.[ch].
89 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
91 * Return NO_SUCH_CHANNEL error in USERS for channel that is
92 secret or private, otherwise it's possible to find out
93 whether a secret channel exists or not. Affected file
96 * If CMODE change fails during the mode setting, assure that
97 the old mode mask is set for the channel back. Affected
100 * Fixed passphrase saving on +a channel on normal server
101 after successful JOIN command. Affected file silcd/command.c.
103 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
105 * Remove server/router operator privileges in DETACH command,
106 since it's possible to resume to server where these
107 privileges would not be allowed for the client. Affected
108 file silcd/command.c.
110 * Do not set to wait for backup in rehash of the server.
111 Affected file silcd/server.c.
113 * Do not check listener sockets when counting how many
114 socket connections we have. Affected file is
117 * Do not announce disconnected clients that are remaining
118 in history (for WHOWAS). This is because SIGNOFF notify
119 for these has been sent earlier already. Affected file
122 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
124 * Buffer overflow with CUMODE command's mode->mode character
125 conversion. Reported by Ville Räsänen. Affected file
126 lib/silcutil/silcutil.c.
128 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
130 * Allow heartbeat packets to go disabled connections anyway.
131 Affected files silcd/server.c and silcd/packet_send.c.
133 * Do not broadcast New Channel packets with List flag set
134 in the packet to backup routers. The router must check
135 for the correctness of the packets before sending them.
136 It is possible that router will have enforce Channel ID
137 change and this would cause desync in the backup router.
138 Affected file silcd/packet_receive.c.
140 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
141 are handled in list parsing. They are not list packets
142 anymore. Affected file silcd/packet_receive.c.
144 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
146 * Stop waiting for backup router through the timeout, not
147 directly after backup router has arrived. Affected file
150 * Do not re-create channel keys and send them when removing
151 clients in server shutdown. Affected files are
152 silcd/server_internal.h and silcd/server_util.c.
154 * Notify distribution to backup routers was missing from
155 the silc_server_send_notify_dest function which caused
156 desyncing problems with backup router. Affected file is
159 * The client's channel removing was working wrong on
160 backup router. It assumed that it doesn't know global
161 information but backup router does know. For this reason
162 it could remove channel when it wasn't supposed to do that.
163 Affected file silcd/server.c and silcd/server_util.c.
165 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
167 * Stop for a couple seconds after badkup router has become
168 primary router. Affected file silcd/server.c.
170 * Added silc_server_remove_servers_by_server, which is used
171 to remove servers originated from some other server. Also
172 clients of those servers can be removed too. Affected file
173 silcd/server_util.[ch].
175 * When removing clients after a server has signed of remove
176 also all servers behind that server (unless they are known
177 to be available locally), and send SERVER_SIGNOFF for each
178 of the server separately. Also the signed off clients are
179 sent now separately per signed off server. The affected files
180 are silcd/server.c and silcd/server_util.[ch].
182 * All servers added with silc_idlist_add_server must always
183 have both "router" and "connection" pointers set. Otherwise,
184 bad server entries may be left around in the cache.
185 Affected file silcd/command_reply.c.
187 * Do not create the channel key in NEW_CHANNEL packet
188 processing if the channel is empty. Affected file
189 silcd/packet_receive.c.
191 * Completed backup router support for standalone routers.
192 Supports also servers in the cell that do not use the backup
195 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
197 * Fixed a bug in silc_string_regexify which did not add '^'
198 at the start of each string, and thus the matching was
199 not explicit. For example ban list iikone@*!*@* would
200 match also "priikone", which is wrong, it would have to be
201 *iikone@*!*@* to match also "priikone". Affected
202 file lib/silcutil/unix/silcunixutil.c.
204 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
206 * Enable all local server connections before updating client
207 caches when we've become backup router. Otherwise, signoff
208 packets may not reach the clients. Affected files are
209 silcd/server.c and silcd/server_util.[ch].
211 * Fixed a bug in version string parsing which could crash
212 the program with specially formatted version string.
213 Bug reported and patch provided by Ville Räsänen. Affected
214 file lib/silcutil/silcutil.c.
216 * Handle the disconnection immediately when DISCONNECT
217 packet is received in server. Affected file silcd/server.c.
219 * Primary router now waits a short time (10 seconds) for
220 backup router connection before accepting any other
221 connection (except local). Affected file silcd/server.c,
224 * Fixed a crash in client libary in NICK_CHANGE notify when
225 NICK_CHANGE arrived for client entry we are resolving
226 currently. Affected file lib/silcclient/client_notify.c.
228 * Call the sconn->callback completion even if error had
229 occurred. Start reconnecting always if connection to
230 primary router fails during backup router protocol.
231 Affected files silcd/server.c and server_backup.c.
233 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
235 * Added functions silc_server_send_opers and
236 silc_server_send_opers_notify to send packets stricly
237 to operators. Added macro SILC_SERVER_SEND_OPERS macro
238 to send variable argument notify to operators.
239 Affected files silcd/packet_send.[ch] and silcd/server.h.
241 * Removed UMODE rights checking with UMODE_CHANGE notify.
242 Affected file silcd/packet_receive.c.
244 * Server/router operator now receives notify when network
245 switches to backup router and when it resumes the use of
246 primary router. Affected file silcd/server.c and
247 silcd/server_backup.c.
249 * Fixed the updating of client information after backup
250 resuming protocol is over; update all except local clients
251 to the new primary router. The affected file is
254 * Added support for closing active connections in rehash
255 that were unconfigured by the user. Supports currently
256 closing server and router connections. Affected file
259 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
261 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
263 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
264 is NULL since seems that on some platforms NULL is allowed
265 and on some it's not. Fallback encoding is used instead.
266 Affected file lib/silcutil/silcstrutil.c.
268 * Fixed statistics updating for incoming server connection
269 which could cause problems when re-connecting. Affected
272 * Preliminary backup router support for standalone router
273 added. Affected files in silcd/.
275 * Mark server connections in backup router disabled before
276 and after backup protocol. Affected file is
277 silcd/server_backup.c.
279 * Added support for reconnecting to remote server connection
280 even if the protocol fails, and if the configuration wants
281 us to keep trying to connect anyway.
283 Server connection is not allowed to backup router if
284 backup router does not have connection to primary router yet.
286 Affected file is silcd/server.c.
288 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
290 * Added silc_client_udpate_server function to update changed
291 server info. Affected file lib/silcclient/idlist.[ch].
293 * Added check for server entries that are being resolved when
294 notify is received. If being resolved, handle the received
295 notify only after it's resolved so that all notifys are
296 handled in same order as received from the server.
298 Added similar resolver check to channel entries. Every
299 notify that cause resolving of any information that affects
300 channel entry marks the channel entry in waiting state.
301 After whatever resolving is over the waiters are signalled
302 and only then the notifys are handled in the same order
303 as delivered from the server.
305 Affected files are lib/silcclient/idlist.[ch], and
308 * Fixed KILLED notify handling in normal server. Affected
309 file silcd/packet_receive.c.
311 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
312 is locally connected, or was locally connected (but may
313 be detached and connection is not active). Added also
314 SILC_IS_LOCAL for checking this status. Affected files
315 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
316 silcd/server.c and silcd/server_internal.h.
318 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
320 * Don't send or handle TOPIC_SET if topic is already set and
321 is same as being set. Affected files silcd/command.c and
322 silcd/packet_receive.c.
324 * Fixed CMODE change rights checking to work correctly when
325 removing modes by operator. Affected file is
328 * Fixed some handling with New Channel packet in router and
329 fixed some CMODE_CHANGE notify handling in server and router.
330 Affected file is silcd/packet_receive.c.
332 * Changed "disconnect" client operation to include the
333 reason of the disconnection and optional disconnection
334 message. Affected file lib/silcclient/silcclient.h.
336 * Made the compilation of lib/contrib/ stuff conditional.
337 Affected files configure.in.pre, lib/contrib/Makefile.am.
339 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
341 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
342 to the sender of the notify too, to avoid situation where two
343 notifys are in the network at the same time going to oppsite
344 directions. Affected file silcd/packet_receice.c.
346 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
348 * Delete the client from channel even if the cilent->id is
349 NULL. It was possible that client was deleted without
350 removing from channels (theoretically at least). Affected
351 file silcd/server.c and silcd/server_util.c.
353 * Free the client data too when resuming is not successful.
354 Affected file silcd/packet_receive.c.
356 * Merged some code from c0ffee's silc-plugin. Affected files
357 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
359 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
360 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
361 to the primary router connection, the other one returns
362 TRUE if packet must be broadcasted to network.
364 * All notifys that are destined to primary router (to network)
365 are now automatically sent to backup routers even if the
366 router is standalone (and has backup router). Affected files
369 * Added --without-irssi and --without-silcd configuration
370 options for disabling the compilation of these applications.
371 Affected file configure.in.pre and prepare.
373 Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
375 * Implemented SILC_STRING_BMP and SILC_STRING_UNIVERSAL for
376 UTF-8 encoding and decoding. Added also new encodings
377 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
379 Added also SILC_STRING_LANGUAGE which is language and charset
380 specific encoder and decoer for those platforms that support
381 iconv(). It can convert the UTF-8 to and from the locale
382 specific character set.
384 Affected file lib/silcutil/silcstrutil.[ch].
386 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.
388 * Added function silc_get_command_name to the file
389 lib/silcutil/silcutil.[ch].
391 * Improved the server debug output a bit. Affected files are
394 Wed Jun 19 17:46:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
396 * Save the channel passphrase when received succesful JOIN
397 command reply from router, on normal server. Otherwise
398 joinig +a channels from normal server is not possible.
399 Affected file silcd/command.c.
401 * Fixed a bug in TOPIC_SET notify handling. The notifier
402 may be other than client too, like server or channel.
403 It expected it to always be only client and ignored the
404 notify. Affected file silcd/packet_recieve.c.
406 * Removed some (unnecessary) debug printing from
407 lib/silccore/silcid.c and lib/silccore/silcargument.c.
409 * Do not force CMODE_CHANGE when server is announcing new
412 Router announces stuff only after server reannounces channel
413 after CHANNEL_CHANGE notify.
415 These fixes optimizes the announcing procedure, and perhaps
416 fixes some problems too. Affected file silcd/packet_receive.c.
418 * Fixed SERVER_SIGNOFF sending to local clients. It was
419 totally broken and sent the notify to all local clients,
420 instead of only to those that was on same channel as the
421 signing off clients. Affected file silcd/server_util.c.
423 * Added -D option to server. It can be used to give debug
424 level. The levels are from 0 - 99, and are predefined for
425 smooth server debugging. (see silcd.c for the predefined
426 levels). Affected file silcd/server.c.
428 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
430 * Fixed a bug in Irssi SILC client to close the connection
431 properly when disconnecting from server. Affected file
432 irssi/src/silc/core/client_ops.c.
434 Tue Jun 18 17:14:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
436 * When authenticating as founder during JOIN command, check
437 that the one authenticating becomes the only founder on the
438 channel. Affected file silcd/command.c.
440 * Better checking for founder mode setting when CUMODE_CHANGE
441 notify is received. Affected file silcd/packet_receive.c.
443 * Close all connections when shutting down the server by sending
444 DISCONNECT packet. Close all listeners too when shutting
445 down the server. Affected file silcd/server.c.
447 * Handle DISCONNECT packet correctly in client library by
448 calling the "disconnect" client operation. Affected file
449 lib/silcclient/client.c.
451 * Handle local errors correctly during resuming. Affected
452 file lib/silcclient/client.c.
454 Tue Jun 18 10:26:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
456 * The log file is not dupped internally anymore in
457 lib/silcutil/silclog.c. Fixed memory leaks too.
459 * The scheduler now dispatches all pending timeout tasks
460 when it is uninitialized with silc_schedule_uninit.
461 Affected file lib/silcutil/silcschedule.c.
463 Mon Jun 17 21:30:55 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
465 * Added --enable-stack-trace option to configure. Added
466 memory allocation stack trace support. Added files
467 lib/silcutil/stacktrace.[ch]. Affected files are
468 lib/silcutil/silcmemory.[ch].
470 * Fixed memory leaks from libraries and server. Affected
471 files around the tree.
473 * Reverted back a fix made to CUMODE which broke it.
474 Affected file silcd/command.c.
476 Sun Jun 16 11:49:45 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
478 * Added SILC_MESSAGE_FLAG_UTF8 to the protocol specs and the
479 core library, and implemented it. All textual messages SHOULD
480 use this flag and the message MUST be UTF-8 encoded.
481 All text messages sent by Irssi SILC client are now UTF-8
482 encoded (regardless whether the terminal supports UTF-8 or not).
483 Affected files are lib/silccore/silcchannel.h,
484 irssi/src/silc/core/silc-servers.c, silc-channels.c and
487 Sat Jun 15 18:23:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
489 * Added lots of new statistics updating that was missing from
490 the server and router code. Affected files in silcd/.
492 * Sending SIGUSR1 signal to server now dumps the current
493 server statistics into /tmp directory. Affected file is
496 * ROBODoc documented the lib/silccrypt/silchash.h. Improved
497 the SILC Hash Interface also. Added new functions
498 silc_hash_get_name, silc_hash_init, silc_hash_update and
499 silc_hash_final. Affected file lib/silccrypt/silchash.c.
501 Sat Jun 15 12:09:14 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
503 * Added some better info printing for client during connecting.
504 Affected file silcd/server_util.c.
506 * Implemented the SILC_CHANNEL_UMODE_QUIET mode that can be used
507 to silence a user on a channel. Affected files are
508 lib/silcclient/client_channel.c, irssi/src/silc/core/client_ops.c,
509 irssi/src/fe-common/silc/module-formats.[ch], silcd/command.c
510 and silcd/packet_receive.c.
512 * Fixed a fatal bug in handling of malformed command payload.
513 Affected file silcd/command.c.
515 * Fixed a double free when announcing channel users to router.
516 Affected file silcd/server.c.
518 * After successful authentication to channel founder mode, check
519 that there isn't anyone else with founder mode on the channel.
520 The one that authenticated will become founder and anyone
521 else is demoted. Affected file silcd/command.c.
523 * Added error printing of any error that has occurred during
524 any command in client library. Affected file is
525 irssi/src/silc/core/client_ops.c.
527 * Removed some error printing from the client library and left
528 it for the application to worry (from the error status it
529 receives in 'command' client operation. Affected file is
530 lib/silcclient/command.c.
532 Fri Jun 14 22:59:02 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
534 * Added new status types KEY_AGREEMENT_ALREADY_STARTED and
535 KEY_AGREEMENT_SELF_DENIED to lib/silcclient/silcclient.h.
536 Starting key agreement with itself is denied. Affected file
537 is lib/silcclient/client_keyagr.c.
539 * Fixed some error checkings from the SFTP library which caused
540 misbehaviour. Affected files are lib/silcsftp/sftp_client.c
541 and lib/silcsftp/sftp_util.c.
543 * Added new "debug" and "debug_string" settings to Irssi SILC
544 client which can be used to print runtime debugging on the
545 Irssi's screen. Available when compiled with --enable-debug
546 option. Affected file irssi/src/silc/core/silc-core.c.
548 Tue Jun 11 16:36:02 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
550 * Fixed a missing variadic parameter in a function call that
551 caused server crash when a non-allowed connection arrived.
552 Reported by Richard Becker. Affected file silcd/server.c.
554 Mon Jun 10 16:29:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
556 * Added WATCH list sending to backup routers from router.
557 The WATCH command is sent by the router to the backup
558 router. Affected file silcd/command.c.
560 * Mark the backup_router flag for RouterConnection entry
561 if the backup router stuff is defined in the config file.
562 Affected file silcd/serverconfig.c.
564 * Fixed some backup data sending around the code to work better
565 if the router is standalone router. Not all places were fixed.
566 Affected file silcd/packet_receive.c, silcd/packet_send.c,
569 * Fixed the router connecting when connecting to multiple
570 routers. It ignored every other router except the first
571 one. Affected file silcd/server.c.
573 Mon Jun 10 09:28:21 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
575 * Made the private key generation after expiration optional.

1086 * Changed the channel message payload's MAC generation to
1087 include the IV in the MAC as well. This way all relevant
1088 parts of the channel message payload are authenticated also
1089 with the channel message MAC (and not only by packet MAC).
1090 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1091 Affected file is lib/silccore/silcchannel.c.
1093 * Fixed the SKE to save the remote version, since the
1094 silc_ske_parse_version mistakenly checked wrong version,
1095 after it replaced the start payload. Affected files are
1096 lib/silcske/silcske.[ch].
1098 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1100 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
1101 string utility functions. Added there also new functions
1102 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
1103 Affected files lib/silcutil/silcstrutil.[ch].
1105 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
1106 files are lib/silcutil/silcstrutil.[ch].
1108 * Defined that the security property fields in SKE SHOULD be
1109 UTF-8 encoded, defined that version string MUST be US-ASCII
1110 encoded, defined that passphrases sent in connection
1111 authentication protocol MUST be UTF-8 encoded. Implemented
1112 these to the client and server. Defined also that other
1113 passphrases sent in the protocol MUST be UTF-8 encoded.
1114 Affected files are lib/silcske/silcske.c,
1115 lib/silcclient/protocol.c, silcd/protocol.c,
1116 silcd/serverconfig.c, and lib/silccore/silcauth.c.
1118 * Changed the silc_client_close_connection interface to not
1119 need the SilcSocketConnection which should not be visible
1120 to application. Affected files are lib/silcclient/client.c
1121 and lib/silcclient/silcclient.h.
1123 * Rewrote the text for Private Message Key Payload in the
1124 protocol specification. Protocol TODO #11.
1126 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1128 * Upgraded the protocol version to 1.1, updated protocol specs
1131 * Added the nickname as new argument to NICK_CHANGE notify and
1132 added it to protocol specs and implemented it to client and
1133 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
1134 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
1135 lib/silcclient/client_notify.c.
1137 * Added the killer's client ID to the KILLED notify and added
1138 it to protocol specs and implemented it to client and server.
1139 Protocol TODO #13. Affected files are silcd/command.c,
1140 silcd/packet_receive.c, packet_send.[ch],
1141 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1142 The killer's client entry is now returned to application in
1143 the `notify' client operation.
1145 * Fixed the Max Argument fields that had too large value set
1146 in the protocol specs. Protocol TODO #14.
1148 * Added the LEAVE command reply to return the ID of parted
1149 channel. Updated protocol specs and implemented it to the
1150 client and server. Protocol TODO #15. Affected files are
1151 silcd/command.c, lib/silcclient/command_reply.c. The channel
1152 entry is now returned to application in the `command_reply'
1155 * Rewrote the version SKE version checking in client libary
1156 and in server to use the silc_parse_version_string. Affected
1157 files are lib/silcclient/protocol.c, silcd/protocol.c.
1159 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
1160 commands that was missing it, and updated protocol specs and
1161 the server implementation. Protocol TODO #10. The affected
1162 file is silcd/command.c.
1164 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1165 generic reply to a generic request (REQUEST flag), and
1166 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1167 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1168 to define the payload for DATA flag. Added the flags to
1169 the implementation. Protocol TODO #9. Affected file is
1170 lib/silccore/silcchannel.h.
1172 Changed the client library to return the message length
1173 to application as well in the channel_message and private_message
1174 client operations. Affected files are
1175 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
1176 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
1177 and lib/silcclient/client_ops_example.c.
1179 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
1180 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
1181 the channel. Updated protocol specs and impelemented this
1182 to client and server. Protocol TODO #6. Affected files are
1183 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
1184 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
1186 Added new options m and M to CMODE command in Irssi SILC
1187 client to set these modes.
1189 * Deprecated all administrative commands from SILC protocol
1190 since they are highly implementation specific commands.
1191 Updated protocol specs. Moved the old commands in
1192 implementations to private range of command types. Affected
1193 files are silcd/command.c, lib/silcclient/command.c and
1194 lib/silcclient/command_reply.c. Protocol TODO #8.
1196 * Fixed a bug in server where sending unknown command crashes
1197 the server. Affected file silcd/command.c.
1199 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1201 * Added SILC_PROTOCOLVERSION macro to check protocol version
1202 of a socket connection. The affected file is
1203 lib/silcutil/silcsockconn.h.
1205 * Added better error logging in rekey protocol. Affected file
1208 * Do not check public key types in SKE during rekey. Affected
1209 file lib/silcske/payload.c.
1211 * Fixed the rekey protocol with PFS, which was totally broken.
1212 Affected file silcd/protocol.c.
1214 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1216 * Some client implementations quit network by doing first LEAVE
1217 and then immediately SIGNOFF (like Bombyx). We now do check
1218 after a short time after LEAVE notify and check whether the
1219 client is still valid after LEAVE, and if not we remove it from
1220 cache. Affected file is lib/silcclient/client_notify.c.
1222 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1224 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1225 it's good not to have security holes here.
1227 * Fixed a negative refcount situtuation for the config context.
1228 Affected file is silcd/serverconfig.c.
1230 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1232 * ROBOdoc documented lib/silcutil/silcutil.h.
1234 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1236 * Optimized even more the SilcPacketContext structure. Now
1237 totally saved 16 bytes of memory per context after optimization.
1238 Affected files are lib/silccore/silcpacket.[ch].
1240 * Made strict checks for valid SILC IDs. Affected file is
1241 lib/silccore/silcid.c.
1243 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1245 * Changed the object argument for silc_cipher_register,
1246 silc_hash_register, silc_hmac_register and silc_pkcs_register
1247 to const. Affected files are lib/silccrypt/silccipher.[ch],
1248 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1250 * Changed the silc_get_username and silc_get_real_name to
1251 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1253 * Fixed the Irssi SILC Client to use the silc_get_username and
1254 silc_get_real_name insted of glib routines since the glib
1255 routines only corrupt stack. Fixes the Irssi SILC to work in
1256 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1258 * Fixed the Irssi to not use g_get_home_dir since it crashes
1259 or returns garbage on cygwin and corrupts stack. Added function
1260 get_home_dir to Irssi routines. Affected files are
1261 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1263 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1265 * Made some structure optimizations. SFTP memory FS MemFSEntry
1266 entry structure. Optimized SilcTask structure. Optimized
1267 SilcPacketContext structure.
1269 Affected files lib/silcsftp/sftp_fs_memory.c,
1270 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1272 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1274 * And yet again reverted back the config thing since Johnny
1275 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1278 * Fixed memory leaks from config object. Affected files are
1279 silcd/serverconfig.[ch].
1281 * Added support for adding new connections to the server in rehash.
1282 After rehash they take effect.
1284 Added support for changing the maximum allowed connections in
1285 rehash. The number can grow but going smaller is not supported.
1287 Added function silc_server_num_sockets_by_remote to the
1288 silcd/server_util.[ch].
1290 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1292 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1294 * Added preliminary checking during config parsing for a valid
1295 public/private key and removed further checks in the code.
1296 Affected files are silcd/serverconfig.[ch], server.c.
1298 * Moved functions silc_server_drop() and silc_server_daemonise()
1299 from server.c to silcd.c since they are stricly related to
1300 the application activity.
1302 * Reverted a small part of the automatic ref/unref since
1303 it caused a double unref in some situations. Affected
1304 files are silcd/silcd.[ch], server.c, serverconfig.c.
1306 * Added some .cvsignore files in the lib directory.
1308 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1310 * Fixed silc_net_gethostbyaddr to correctly resolve by
1311 address. Affected file lib/silcutil/silcnet.c.
1313 * Fixed the notify relaying to client. The HMAC to be used
1314 with relayed packets ws wrong and caused decryption failure
1315 at the client end. Affected file is silcd/packet_receive.c.
1317 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1319 * Created new branch silc_protocol_1_0_branch.
1321 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1323 * Changed the silc_server_config_* routines to be SilcServer
1324 independent. They are now officially application specific code
1325 and not part of generic server implementation. Affected files
1326 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1328 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1330 * Added automatic referencing of config context in the
1331 silc_server_config_alloc, and automatic unreferencing in the
1332 silc_server_config_destroy. Affected files are
1333 silcd/serverconfig.[ch], silcd/silcd.c.
1335 * Fixed the silc_log_quick handling in the logging routines.
1336 It didn't log quickly when it was TRUE. Affected file is
1337 lib/silcutil/silclog.c. Also the flush delay was set even
1338 if it was 0 in config file. Affected file is
1339 silcd/serverconfig.c.
1341 * Added support for changing key pair of the server in rehash.
1342 Affected file silcd/server.c.
1344 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1346 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1347 too early, before getting the channel entry. Affected file
1348 is silcd/packet_receive.c.
1350 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1352 * Added functions silc_server_config_[ref/unref], these are used
1353 to prevent that the config object is destroyed.
1355 No longer directly affect global variables silc_log_quick and
1356 silc_log_delay, they are first cached inside the config object
1357 and then applied with silc_server_config_setlogfiles().
1359 silc_server_config_set_defaults() is now internal to
1360 serverconfig.c, there are no reasons to show this internal stuff
1363 Affected files are silcd/serverconfig.[ch].
1365 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1366 fprintf's to stderr, since some code may be executed again after
1367 the server went into the background. Affected files are
1370 * Added rehash support. Added function silc_server_rehash() that
1371 will perform all the basic tasks of the rehashing procedure.
1373 * Added command line option `-x, --hexdump'. This will enable the
1374 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1375 The option `--hexdump' implies `--debug'.
1377 * Fixed a bad bug in the logging APIs (silcutil library) where
1378 the application would crash after calling silc_log_reset_all().
1380 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1382 * Fixed the KICKED notify handling in client library to
1383 correctly remove the channel and all entries from the
1384 channel when I was kicked. This bug crashed the client.
1386 Fixed yet another but in KICKED notify handling to remove
1387 the kicked client correctly from the channel.
1389 Affected file is lib/silcclient/client_notify.c.
1391 * Fixed a minor bug in looking up correct client entry
1392 in KICKED notify in server. Affected file is
1393 silcd/packet_receive.c.
1395 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1396 sources correctly to distribution. Fixes --with-gmp option.
1398 * Removed the manual rehashing from ID Cache, and changed it
1399 to use the SILC Hash Table's auto rehash feature. Affected
1400 file is lib/silccore/silcidcache.c.
1402 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1404 * Fixed a bug in the silc_client_nickname_format function that
1405 handles the multiple same nickname formatting. Two clients
1406 with same nickname caused problems after the first one left
1407 and rejoined. It didn't format the nickname correctly.
1408 Affected file is lib/silcclient/idlist.c.
1410 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1412 * Don't change the topic if olod topic is same as new one.
1413 Affected file is silcd/packet_receive.c.
1415 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1417 * Added cross-reference support to the SILC Documentation
1418 generator. All types across all HTML files are now cross-
1419 referenced. Affected files util/robodoc/generator.c and
1420 scripts/silcdoc/silcdoc.
1422 * Added file lib/silcutil/silctypes.h to include all the
1423 arithmetic type definitions and some macros. Removed
1424 includes/bitmove.h and moved macros to silctypes.h.
1426 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1428 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
1430 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1432 * Added `type' argument to silc_id_payload_parse_id function which
1433 now returns the type of the ID to the sent pointer. Affected
1434 file is lib/silccore/silcid.[ch].
1436 * Added check for CMODE_CHANGE notify type that mode change is
1437 allowed by the sender. Affected file silcd/packet_receive.c.
1439 * Added check for CUMODE_CHANGE notify type that mode change is
1440 allowed by the sender. Affected file silcd/packet_receive.c.
1441 Added the ID type as CUMODE_CHANGE notify type as argument
1442 to the `notify' client operation. Affected files are
1443 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1445 * Added function silc_client_add_server to the client library.
1446 Added support for resolving also channel and server info when
1447 received unknown entity in notify packet. Affected files are
1448 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1450 * Added function silc_command_get_status to return the command
1451 status from the command reply's argument payload. Affected files
1452 are lib/silccore/silccommand.[ch].
1454 * Added check for KICKED notify type that the kicking is
1455 allowed by the client. Affected file silcd/packet_receive.c.
1457 * Created function silc_get_input which can be used to get input
1458 (echo on or off) from user on command line. Affected files are
1459 lib/silcutil/silcutil.[ch].
1461 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1463 * Optimized silc_server_packet_relay_to_channel function.
1464 Added new function silc_channel_message_payload_encrypt which
1465 can be called directly if channel message payload needs to
1466 be encrypted and is already encoded (no need to call _encode
1467 function). Packet relaying is now done by router without any
1468 extra memory allocations. Affected files are
1469 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1470 silcd/packet_send.c.
1472 * Fixed the INVITE notify handling. It took wrong arguments
1473 as invite list and invite delete. Affected file is
1474 silcd/packet_receive.c.
1476 * Added check for TOPIC_SET notify type that the topic change is
1477 allowed by the client. Affected file silcd/packet_receive.c.
1479 * Added check for INVITE notify type that inviting is allowed by
1480 the client. Affected file silcd/packet_receive.c.
1482 * Changed the silc_server_client_on_channel to return the
1483 SilcChannelClientEntry as well. Moved the function
1484 silc_server_check_cmode_rights to server_util.[ch].
1485 Affected files are silcd/server_util.[ch], silcd/command.c.
1487 * Added function silc_server_check_umode_rights to check whether
1488 changing client's user mode is allowed. Added check for
1489 UMODE_CHANGE notify type that the umode change is allowed
1490 by the client. Affected files are silcd/server_util.[ch],
1491 silcd/packet_receive.c and silcd/command.c.
1493 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1495 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1496 ID length. It ignored that ID can be IPv6 based as well.
1497 Affected file lib/silccore/silcpacket.h.
1499 * Fixed the silc_id_id2str and silc_id_str2id to take the
1500 IPv6 address offset's into consideration. Affecte file is
1501 lib/silccore/silcid.c.
1503 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1505 * Fixed the internal Unix scheduler functions to check for
1506 NULL context they may receive. The affected file is
1507 lib/silcutil/unix/silcunixschedule.c.
1509 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1511 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1512 can specify different directory with --home command line
1513 parameter. Affected files irssi/src/silc/core/client_ops.c,
1516 * SILC-specific commands aren't now executed if the active server
1517 isn't of SILC-type, so there won't be problems with having
1518 IRC and SILC protocol support in same client. Affected files
1519 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1522 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1524 * Improved the signal support in SILC Schedule. Added new
1525 function silc_schedule_signal_call which is used by application
1526 to mark a signal to be called. It is now safe to perform
1527 any kind of tasks in signal callbacks since it is guaranteed
1528 that the application specified signal callback is called
1529 after the signal is over. Affected files are
1530 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1532 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1534 * Added `name' field to SilcChannelPrivateKey to represent
1535 application given name for the key. Moved also the context from
1536 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1537 Added the `name' argument also to the function
1538 silc_client_add_channel_private_key.
1540 Added function silc_client_current_channel_private_key to set the
1541 current channel private key in use.
1543 Added "change" command to KEY command which can be used to change
1544 the current channel private key. Bound the command also to
1545 alt+K (Alt+Shift+k).
1547 Also affected files lib/silcclient/client_channel.c,
1548 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1550 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1552 * Added silc_rng_get_byte_fast function in to the
1553 lib/silccrypt/silcrng.[ch].
1555 * Changed the interface of silc_packet_assemble and the
1556 silc_packet_send_prepare. If silc_packet_assmble is now
1557 called the application does not call silc_packet_send_prepare
1558 because the library will call it automatically. These
1559 interfaces now also return a reference to the outgoing buffer
1560 which includes the assembled packet, which the application can
1561 use to encrypt the packet.
1563 Affected files are lib/silccore/silcpacket.[ch],
1564 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1565 silcd/packet_send.c, server_backup.c and packet_receive.c.
1567 * Fixed a packet sending bug on very high load, where outgoing
1568 packet queue wasn't handled correctly and packets got corrupted.
1569 Affected files are lib/silcutil/*/silc*sockconn.c,
1570 lib/silcclient/client.c and silcd/server.c.
1572 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1574 * Added macro SILC_PACKET_DATALEN which can be used during
1575 packet assembling to check whether the data to be added to
1576 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1577 len is truncated until it fits it.
1579 Added checks for maximum length of channel message payload and
1580 private message payload also.
1582 Added checks for maximum packet length in server and in
1585 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1586 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1587 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1588 lib/silcclient/client_prvmsg.c.
1590 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1592 * Added silc_server_packet_queue_purge call to the
1593 silc_server_disconnect_remote to assure that all data in the
1594 queue before disconnecting is sent to the network. Affected
1595 file silcd/server.c.
1597 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1599 * Added the deleting of server's own ID cache entry to the
1600 silc_server_free function. Free also everything else that
1601 has been allocated in silc_server_init. The affected file
1604 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1606 * Added functions silc_parse_version_string, silc_version_to_num,
1607 and silc_ske_parse_version to parse SILC protocol style version
1608 strings. Affected files lib/silcutil/silcutil.[ch] and
1609 lib/silcske/silcske.[ch].
1611 * Added new configuration params: version_protocol, version_software
1612 and version_software_vendor to specify what version the remote
1613 host must at least be to be able to connect to server. The vendor
1614 string can be regex matched too. Added new function
1615 silc_server_connection_allowed to check maximum number of allowed
1616 connections, and allowed versions for incoming connections.
1617 Affected files are silcd/server.c, server_util.[ch] and
1620 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1622 * Added preliminary support for signals in scheduler. The
1623 signals we care about are now blocked always when the scheduler
1624 is locked. This way we can synchronise the use of signal with
1625 scheduler. It is guaranteed that when signal occurs the scheduler
1626 is not locked, and thus new tasks can be safely added to the
1629 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1630 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1631 Added new platform specific routines
1632 silc_schedule_internal_signals_[un]block and
1633 silc_schedule_internal_signal_[un]register.
1635 Added new functions to SILC Schedule API:
1636 silc_schedule_signal_[un]register. Each signal that application
1637 is going to use should be registered to the scheduler.
1639 Affected files are lib/silcutil/silcschedule.[ch],
1640 lib/silcutil/*/silc*schedule.c.
1642 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1644 * Check for unauthenticated client and server in the
1645 silc_server_new_client and silc_server_new_server functions.
1646 Affected file silcd/packet_receive.c.
1648 * Added function silc_string_is_ascii to check whether given
1649 string is 7-bit ASCII string. Affected files are
1650 lib/silcutil/silcutil.[ch].
1652 * Added function silc_id_is_valid_server_id into the
1653 silcd/serverid.c and added checking for valid Server ID's in
1654 silc_server_new_server. The Server ID must always be based
1655 on the server's public IP address.
1657 * Added logging of DISCONNECT packet message in the server.
1658 Affected file silcd/server.c.
1660 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1662 * Changed all library interfaces that use Global RNG to also
1663 accept SilcRng as argument. Affected files are
1664 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1665 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1666 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1667 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1668 lib/silccrypt/rsa.c.
1670 * Added function silc_pkcs_generate_key to the
1671 lib/silccrypt/silcpkcs.[ch] for applications so that they
1672 don't need to do pkcs->pkcs->init calls anymore.
1674 * Remove SilcSocketConnection from the SFTP API since it really
1675 wasn't needed there. The application has the information
1676 saved in its contexts anyway and the SFTP layer doesn't need
1677 know about it. Affected files lib/silcsft/silcsftp.h and
1678 lib/silcsftp/sftp_[server/client].c.
1680 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1681 The SilcSimContext is not SilcSim.
1683 * Fixed possible buffer overflows in silc_id_render in the
1684 lib/silcutil/silcutil.c.
1686 * On EPOC the global crypto module lists are not used at all
1687 in the crypto library. Added support for using the constant
1688 algorithm list on EPOC. Affected files are
1689 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1692 * Fixed the handling of third parameter of KICKED notify, since
1693 it was mistakenly updated to SILC Protocol 1.0 even though it
1694 is to be included in 1.1. Since it is not in 1.0 it is not
1695 mandatory, and this fix now handles it only if it is provided,
1696 and it is not error if it is not provided. Affected file
1697 lib/silcclient/client_notify.c.
1699 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1701 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1702 client. Affected file irssi/src/silc/core/client_ops.c.
1704 * Merged with Irssi 0.8.4 from irssi.org CVS.
1706 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1708 * Check for valid socket connection in client entries before
1709 sending any messages. Fixes a crash, but doesn't fix some
1710 other underlaying bug that is lurking there. Affected
1711 file silcd/packet_send.c.
1713 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1715 * $usermode, $cumode and $cumode_space expandos shouldn't do
1716 anything with non-SILC server records. Affected file
1717 irssi/src/silc/core/silc-expandos.c
1719 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1721 * Fixed the silc_net_check_[host/local]_by_sock to support
1722 IPv6 bound sockets as well. Now they can return IPv6 addresses
1723 as well. Affected file lib/silcutil/silcnet.c.
1725 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1726 Affected lib/silcutil/unix/silcunixnet.c.
1728 * Fixed ID rendering (at least on some platforms, not NetBSD)
1729 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1731 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1733 * Added silc_hash_public_key and silc_hash_public_key_compare
1734 functions to be used with SilcHashTable. They can be used to
1735 hash public keys and compare public keys in hash table. Affected
1736 file lib/silcutil/silcutil.[ch].
1738 * Added support for specifying multiple public keys for Client
1739 connection section in server configuration file. This makes it
1740 possible to accept multiple public keys from same host, or to
1741 make a section that accepts any incoming host, and have the
1742 accepted public keys listed in the section.
1744 Added functions silc_sever_[find/get]_public_key, added the
1745 support for this actually to all connection sections but only
1746 the Client section is currently allowed to specify multiple
1749 Affected files are silcd/server.c, server_internal.h,
1750 command.c, protocol.c, server_util.[ch], packet_receive.c.
1752 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1754 * Merged Irssi 0.8.2 from irssi.org CVS.
1756 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1758 * If silc_debug is TRUE, also output standard logging messages
1759 to stderr with the debug output.
1761 Made silc_log_reset_all() flushing all channels before returning.
1762 Also fixed some documentation typos.
1764 Affected files are lib/silcutil/silclog.[ch].
1766 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1768 * Fixed the server to check correctly the amount of connections
1769 from single host, by checking also the type of the connection.
1770 Fixed also the comparison of number of connections and number
1771 of allowed connections. Affected files are silcd/server.c,
1774 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1776 * Fixed the USERS command reply to save the user's mode on the
1777 channel as well. Fixed JOIN command reply to check whether a
1778 client is on channel already and not join it twice. Affected
1779 file lib/silcclient/command_reply.c.
1781 * Added new file silc-expandos.c into irssi/silc/core/ to return
1782 various stuff for various signal for the statusbar etc. updating.
1783 Now Irssi SILC client prints channel user modes etc. on the
1786 * The user mode (like server/router operator changes) is now shown
1787 on the Irssi SILC client's statusbar. The affected files are
1788 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1790 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1792 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1793 to SILC_SCHEDULE_[UN]LOCK macros.
1795 * Added more error printing to logs in server code. Affected
1796 files silcd/server.c and silcd/protocol.c.
1798 * Fixed -S option parsing in Irssi SILC Client. Affected file
1799 irssi/src/silc/core/silc-core.c.
1801 * Added silc_buffer_alloc_size function. Affected file is
1802 lib/silcutil/silcbuffer.h.
1804 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1806 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1807 constants. Affected files in
1808 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1811 * Changed the internal SFTP Memory FS table to const. Affected
1812 file lib/silcsftp/sftp_fs_memory.c.

1816 * Fixed the buffer formatting and unformatting routines to
1817 check the size of 64 bits types with sizeof(). Affected
1818 file is lib/silcutil/silcbuffmt.c.
1820 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1824 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1826 * Changed all integer type names:
1827 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1828 to avoid collisions with other libraries using same type names
1831 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1833 * Added `prefer_ipv6' argument to the functions
1834 silc_net_gethostbyname[_async]. If it is TRUE it will return
1835 IPv6 address over IPv4. If FALSE IPv4 address is returned
1836 even if IPv6 address was found. Affected files
1837 lib/silcutil/silcnet.[ch].
1839 * Added support silc_net_create_connection[_async] to fallback
1840 to IPv4 address if IPv6 address could not be used (like if
1841 it doesn't work on a specific system). Affected file in
1842 lib/silcutil/unix/silcunixnet.c.
1844 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1846 * Added silc_schedule_reinit function to do the enlarging
1847 of the max tasks handling capabilities of the scheduler.
1848 Affected files lib/silcutil/silcschedule.[ch].
1850 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1852 * Added automatic extern "C" { ... } for C++ compilers so the
1853 application does not need to define them. Affected file
1854 includes/silcincludes.h.
1856 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1857 old name went against naming convention. Applications now
1858 include "silcclient.h" instead of "clientlibincludes.h".
1859 Removed includes/clientlibincludes.h, it is redundant now.
1861 * Renamed includes/version.h to silcversion.h.
1863 * Added really preliminary support for OS/2 into the util
1864 library. Only thread & mutex API is implemented, others
1865 are still to be implemented. Created the lib/silcutil/os2/
1866 directory. Created also file includes/silcos2.h.
1868 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1873 includes/silcbeos.h.
1875 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1877 * Added proper initializations to silc's irssi code, so it's
1878 now possible to load it as module. Affected files
1879 irssi/src/silc/core/silc-core.c,
1880 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c

1899 * Added `user_count' to the SilcChannelEntry which now tells the
1900 number of users on the channel. The user count is now saved
1901 in normal server of global channels as well. Affected files
1902 silcd/server.c, idlist.h, packet_receive.c and command.c.
1904 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1905 include file utility functions.
1907 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1908 instead of calling directly OS routines.
1910 * Fixed NICK change printing in Irssi SILC Client. Fixed
1911 KICKED notify printing in Irssi SILC Client. Affected file
1912 irssi/src/silc/core/client_ops.c.
1914 * Fixed a NICK change bug in client library, to not recreate the
1915 client_entry->channels hash table everytime nick is changed.
1916 Affected file lib/silcclient/client.c.
1918 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1920 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1921 the SKE interface a bit.
1923 * Fixed padding problem in PKCS#1. The padding was not actually
1924 random since the random number generator was used incorrectly.
1925 This security bug affects only when encrypting with PKCS#1, and
1926 it is not currently used at all in SILC. SILC only use signing
1927 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1929 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1940 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1941 key_exchange_timeout, conn_auth_timeout, connections_max,
1944 Implemented all the new config settings handling in the server.
1946 Optimized the use of SKE Mutual flag usage. Use it only
1947 if connection authentication protocol is not based in public
1950 Renamed all SilcServerConfigSection* to SilcServerConfig*
1951 to have a bit shorter names.
1953 Affected files silcd/serverconfig.[ch], server.[ch], and
1956 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1987 is now done in silc_core_init() which also fixes autoconnecting
1990 Affected files irssi/src/silc/core/silc-core.c,
1991 irssi/src/fe-text/silc.c.
1993 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1995 * Added new configuration options and blocks:
1996 keepalive_secs, reconnect_count, reconnect_interval,
1997 reconnect_interval_max, reconnect_keep_trying and
1998 require_reverser_lookup. Added ConnectionParam block, and
1999 implemented the connection parameters when connecting as
2000 initiator and when accepting connections as responder.
2002 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
2003 whether given configuration value has been given already.
2005 Affected files silcd/serverconfig.[c], server.[c].
2007 * Splitted the doc/example_silcd.conf.in. Separated the crypto
2008 algorithm parts and created new file silcalgs.conf, that
2009 is now included from the example_silcd.conf.in.
2011 * Optimized the silc_server_connect_to_router_second to take
2012 the connection configuration object from the SilcServerConnection
2013 object instead of finding it during the connecting phase.
2014 Added the configuration object to SilcServerConnection struct.
2015 Affected files silcd/server_internal.h, server.c.
2017 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2019 * Add the client on channel after it was resolved at the
2020 channel message receiving, and it was not already on the
2021 channel. Affected file lib/silcclient/client_channel.c.
2023 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2025 * Fixed the public key authentication to allocate always the
2026 destination signature buffer instead of using static buffer.
2027 Affected file silcd/protocol.c.
2029 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2038 config file, allowing both public key and passphrase based
2039 authentication to be set at the same time.
2041 Added `prefer_passphrase_auth' setting in config file which
2042 can be used to set to prefer passwd auth if both passwd and
2043 public key is set. If not set, public key is preferred.
2044 This has effect only when being initiator (responder will try
2047 Added support for authentication with passphrase and public key
2048 at the same time. The passphrase is tried first always since
2049 it is faster to check.
2051 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2053 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

2087 as part of Toolkit documentation.
2089 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2091 * Fixed CUMODE_CHANGE notify handling to change the mode of
2092 correct client. Affected file lib/silcclient/client_notify.c.
2094 * Make silc_rng_alloc fail if it cannot allocate the sha1
2095 hash algorithm. Affected file lib/silccrypt/silcrng.c.
2097 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2099 * Fixed the file transfer's key agreement payload to include
2100 zero port also if the hostname is NULL because it could not
2103 Call file transfer monitor callback now also if error occurs
2104 during key agreement protocol.
2106 Changed the silc_client_file_send interface to return the
2107 SilcClientFileError instead of session id. The session ID
2108 is returned into pointer provided as argument.
2110 Check that the file exists locally before sending the
2111 file transfer request at all.
2113 Affected file lib/silcclient/client_ftp.c, silcapi.h.
2115 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
2116 error than can occur while key agreement protocol. Affected
2117 file lib/silcclient/silcapi.h.
2119 * Fixed the event_mode CMODE handler to not crash when mode
2120 is changed and +k mode is set in the channel. Affected file
2121 irssi/src/silc/core/silc-channels.c.
2123 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2124 SILC_LOG_WARNING to give out Warning and not Error. Affected
2125 file lib/silcutil/silclog.c.
2127 * Fixed the channel message payload decryption in the function
2128 silc_channel_message_payload_decrypt to not modify the original
2129 buffer before it is verified that the message decrypted
2130 correctly. Otherwise, next time it is called with correct
2131 channel key it won't encrypt since the payload is corrupted.
2132 Affected file lib/silccore/silcchannel.c.
2134 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2136 * Do not constantly resize the window. A fix patch by cras.
2137 Affected file irssi/src/fe-text/screen.c.
2139 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2141 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
2142 Affected file lib/silcutil/silcnet.c.
2144 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2146 * Fixed a bug in hash table internal routine for traversing
2147 the table with foreach callback. The current entry may
2148 become invalid in the callback but it was referenced after
2149 the callback returned.
2151 Do not allow auto rehashing of hash table during the
2152 silc_hash_table_foreach operation, for same reasons as it is
2153 not allowed for SilcHashTableList. Affected files are
2154 lib/silcutil/silchashtable.[ch].
2156 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2158 * Defined DLLAPI into silcincludes.h and silcwin32.h for
2159 Win32 DLL. extern's in header files are now declared with
2162 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2164 * Fixed private message handling. It used some old code that
2165 caused the client to crash. Affecte file is
2166 lib/silcclient/client_prvmsg.c.
2168 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2170 * Added function silc_client_add_channel,
2171 silc_client_replace_channel_id, and removed functions
2172 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2173 from client library.
2175 * Added cross reference of the joined channels to the
2176 SilcClientEntry, and changed the SilcChannelEntry's
2177 users list to SilcHashTable. The affected files are
2178 lib/silcclient/idlist.[ch].
2180 * Fixed a bug in hash table tarversing. While the hash table
2181 is traversed with SilcHashTableList the table must not be
2182 rehashed. It is now guaranteed that auto rehashable tables
2183 are not rehashed while tarversing the list. Also defined that
2184 silc_hash_table_rehash must not be called while tarversing
2185 the table. Added function silc_hash_table_list_reset that must
2186 be called after the tarversing is over. The affected files are
2187 lib/silcutil/silchashtable.[ch].
2189 * Changed all hash table traversing to call the new
2190 silc_hash_table_list_reset in server and in client library.
2192 * Added function silc_client_on_channel to return the
2193 SilcChannelUser entry if the specified client entry is joined
2194 on the specified channel. This is exported to application as
2195 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2197 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2199 * Fixed founder regaining problem with JOIN command on normal
2200 server. The notify for mode change must be sent always and
2201 not only if !cmd->pending. Affected file silcd/command.c.
2203 * Fixed the WHOWAS command's reply sending to support the
2204 lists correctly. Affected file silcd/command.c.
2206 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2208 * When sending JOIN command to router for processing the
2209 sender's old command identifier was not saved back to the
2210 sender's command context, fixed now. The affected file is
2213 * Create the key in JOIN command of the router did not return
2214 the channel key, added check for this. Affected file is
2217 * Fixed a channel ID update bug in JOIN command reply. Do
2218 not directly upgrade the ID but call the function
2219 silc_idlist_replace_channel_id if the ID was changed.
2220 Affected file silcd/command_reply.c.
2222 * Fixed memory leaks from command calling if it would fail.
2223 Affected file silcd/command.c.
2225 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2227 * Applied patches from cras:
2229 Memory leak fixes around libaries, irssi window resize fix,
2230 new silclist.h and silcdlist.h, all extern inline changed to
2233 * Removed dotconf from lib/dotconf, not needed anymore.
2235 * Removed TRQ from lib/trq, not needed anymore.
2237 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2238 with server connections. Later this will be configurable
2239 in config file after new config file is done. Affected file
2242 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2244 * Fixed a crash in server related to channel announcements.
2245 Affected file silcd/server.c.
2247 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2249 * Fixed memory leaks in silc_server_create_new_channel*
2250 functions. Affected file silcd/server.c.
2252 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2253 which ID was changed. This way the router will send the
2254 user list for the channel again, and server won't be in
2255 desync in some rare circumstances. Affected file is
2256 silcd/packet_receive.c.
2258 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2260 * Check for NULL socket pointer in the function
2261 silc_server_packet_send_to_channel_real. Affected file
2262 silcd/packet_send.c.
2264 * Fixed the BAN notify handling to correctly remove ban
2265 list. Affected file silcd/packet_receive.c.
2267 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2269 * Fixed some header addition to Toolkit distribution in
2270 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2272 * Added lib/silcclient/client_ops_example.h as an template
2273 file for application programmers to quickly start using
2274 the SilcClientOperation functions in their application.
2275 Updated the lib/silcclient/README as well to tell about this
2276 nice file made available.
2278 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2280 * Call silc_server_remove_from_channels when removing client
2281 entry when NO_SUCH_CLIENT_ID was received. Affected file
2282 is silcd/command_reply.c.
2284 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2286 * Added server & router operator statistics updating. Affected
2287 file silcd/packet_receive.c and silcd/command.c.
2289 * Fixed the SERVER_SIGNOFF notify handling on normal server
2290 not to save the history information for clients. Same was
2291 fixed earlier in remove_clients_by_server function, but not
2292 here. Affected file silcd/packet_receive.c.
2294 * Raised the default connection-retry count from 4 to 7 in
2295 server. Affected file silcd/server.h.
2297 * Cancel any possible reconnect timeouts when we start the
2298 key exchange. Affected file silcd/server.c.
2300 * Do not reconnect on connection failure when SCONNECT was
2301 given. Affected files silcd/server.[ch].
2303 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2305 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2307 * Fixed the NICK command to always give the unformatted
2308 nickname to the one giving the NICK command. If unformatted
2309 nickname is cached already it will be formatted and the
2310 local entry will always get the unformatted nickname.
2311 Affected file lib/silcclient/idlist.c.
2313 * Fixed some double frees from client library commands.
2314 Affected file is lib/silcclient/command.c.
2316 * Fixed CUMODE command in server to assure that no one can
2317 change founder's mode than the founder itself, there was a
2318 little bug. Affected file silcd/command.c.
2320 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2322 * Removed the SilcClientCommandDestructor from the client
2323 libary, it is not needed anymore. Affected files are
2324 lib/silcclient/silcapi.h, command[_reply].[ch],
2325 client_notify, idlist.c.
2327 * Fixed GETKEY command to first resolve client, and then
2328 resolve the server only if the client was not found, instead
2329 of resolving both at the same time. Affected file is
2330 lib/silcclient/command.c.
2332 * Added silc_client_start_key_exchange_cb and lookup the
2333 remote hostname and IP address before starting the key
2334 exchange with server. The affected file is
2335 lib/silcclient/client.c.
2337 * The server's public key is now saved using the IP address
2338 of the server and not the servername for the filename.
2339 The hostname public key filename is checked as an fall back
2340 method if the IP address based filename is not found.
2342 Fixed the GETKEY command to save the fetched server key
2343 in correct filename.
2345 Print the remote server's hostname now when new key is
2346 received during connection process. Affected file is
2347 irssi/src/silc/core/client_ops.c.
2349 * Return always our own public key to the client if it asks
2350 for it with GETKEY command. Affected file silcd/command.c.
2352 * Removed the use_auto_addr variable from default config
2353 file since it was in wrong section. Affected file is
2356 * Fixed TOPIC_CHANGE notification to not route it when it
2357 was sent using silc_server_send_notify_to_channel function.
2358 Affected file silcd/command.c.
2360 * Fixed silc_server_send_notify_kicked to send the kicker's
2361 Client ID also, it was missing. Affected files are
2362 silcd/command.c, silcd/packet_send.[ch].
2364 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2366 * Do not save client history information in SERVER_SIGNOFF.
2367 Fixes the bug in normal server that it does not detect
2368 the client becoming valid after the server becomes back
2369 online. Affected file silcd/server_util.c.
2371 * Added `sock_error' field into the SilcSocketConnection
2372 context. When error occurs during socket operation (read
2373 or write) the error is saved. Added also new function
2374 silc_socket_get_error to return human readable socket error
2375 message. Affected files are lib/silcutil/silcsockconn.[ch],
2376 lib/silcutil/unix/silcunixsockconn.c, and
2377 lib/silcutil/win32/silcwin32sockconn.c.
2379 * The server now prints the socket error message in the
2380 signoff for client. Affected file silcd/server.c.
2382 * Fixed the `created' channel information sending from router
2383 to server in JOIN command. Checks now whether the channel
2384 really was created or not and set it according that.
2386 Fixed the JOIN command to use the client entry's current
2387 ID during the joining procedure instead of the one it sent
2388 in the command (it is checked though), since it can change
2389 between the packet processing and command processing, and
2390 would just case unnecessary pain in the client end. Affected
2391 file silcd/command.c.
2393 * Fixed a channel key payload sending to use correct channel
2394 ID when the server was forced to change the channel's ID by
2395 router. Router sent the key payload with the old Channel ID.
2396 Affected file silcd/packet_receive.c.
2398 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2400 * Call silc_server_save_channel_key only if the key payload
2401 was provided in the JOIN command's command reply. Affected
2402 file silcd/command_reply.c.
2404 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2406 * Fixed silc_mp_sizeinbase to return the value correctly with
2407 MPI. Affected file lib/silcmath/mp_mpi.c.
2409 * Fixed the stop_server signal to correctly stop the scheduler
2410 and gracefully stop the server when SIGTERM or SIGINT signals
2411 are received. Affected file silcd/silcd.c.
2413 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2415 * Simple handling of TERM and HUP signals. Also added some log
2416 flushing call around. Affected file is
2419 * Fixed small bugs in silclog.c. Now buffering output will take
2420 effect after 10 seconds since startup: This will ensure that
2421 no important startup messages are lost. Also output redirection
2422 will preserve original format ([Date] [Type] message).
2423 Affected file is lib/silcutil/silclog.c.
2425 * Added two options to the config file, in the logging section:
2426 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2427 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2429 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2431 * Do not print the warning about log files not being initialized
2432 more than once to avoid excess logging. Affected file is
2433 lib/silcutil/silclog.c.
2435 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2436 the SIM copying in make install in Makefile.am.pre.
2438 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2440 * Rewritten silclog APIs. Globally interesting changes follows:
2441 silc_log_set_files() changed to silc_log_set_file().
2442 silc_log_set_callbacks() changed to silc_log_set_callback().
2443 ROBOdoc documented silclog header file.
2444 SilcLogCb now returns bool to wether inihibit the default
2445 handler or not (to keep the old behaviour return always TRUE).
2446 The new APIs should also fix the problem of the
2447 silcd_error.log file that was written in the current directory.
2450 Log files streams will remain opened after silc_log_set_file()
2451 call, means less CPU usage notably on high traffic servers.
2452 File streams are now full buffered, and flushed to the disk
2453 every 5 minutes, lesses HD activity and CPU usage.
2454 Messages can be redirected, allowing admins to configure
2455 one single logfile for all server messages.
2456 the silc_log_quick global variable to activate fast-logging.
2457 Affected files lib/silcutil/silclog.[ch]
2459 * Changed some code to conform new silclog APIs. Affected
2460 files are doc/example_silcd.conf.in, silcd/server.c
2461 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2464 * Fixed a memory leak that could occur in some situations.
2465 Affected file silcd/serverconfig.c.
2467 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2469 * Added the silc_client_del_client to remove the client from
2470 all channels as well. Affected file lib/silcclient/idlist.c.
2472 * Fixed the client library to correctly remove the client
2473 from all channels when the client entry is being destroyed.
2474 Affected file lib/silcclient/client_notify.c, command.c.
2476 * Added auto-nicking support to the client library. If the
2477 applicatio now sets client->nickname it will be sent to the
2478 server after connecting by the library. This way for example
2479 SILCNICK (or IRCNICK) environment variables will have effect
2480 and always change the nickname automatically to whatever
2481 it is wanted. Affected file lib/silcclient/client.[ch].
2483 * Renamed silc_server_command_bad_chars to the
2484 silc_server_name_bad_chars and moved it to the
2485 silcd/server_util.[ch]. Added also new function
2486 silc_server_name_modify_bad to return nickname that
2487 includes bad characters as new nickname without those
2488 bad characters. This check and modify is now used in
2489 silc_server_new_client when the username is initially set
2490 as nickname, so it must be checked to be valid nickname.
2491 Affected file silcd/packet_receive.c.
2493 * The nickname length is now taken from the packet for real
2494 and not trusted to strlen() since it clearly can return
2495 wrong length for nickname including bad characters. This
2496 also applies to channel names. Affected file silcd/command.c.
2498 * Removed the lib/silcsilm/modules directory. Modules are now
2499 compiled into the lib/silcsim. Fixed the copying of the
2500 modules to follow symbolic links in Makefile.am.pre.
2502 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2504 * Fixed silc_string_regexify list creation. Fixes bugs with
2505 BAN and INVITE commands in server. The affected file is
2506 lib/silcutil/unix/silcunixutil.c.
2508 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2510 * Removed the command destructor entirely from the server's
2511 command and command reply routines. It is not needed, and
2512 its usage was buggy and caused crashes. Affected files are
2513 silcd/command[_reply].[ch].
2515 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2517 * Cancel protocol and NULL sock->protocol if timeout
2518 occurred during protocol. Affected file silcd/server.c.
2520 * Cancel protocol timeouts always before calling the final
2521 callback, to assure that after final callback is called
2522 no other state will be called for the protocol anymore.
2523 Affected file silcd/protocol.c.
2525 * Print error log if incoming connection configuration could
2526 not be found. Affected file silcd/server.c.
2528 * Fixed JOIN command to correctly save the founder mode
2529 to the client on normal SILC server, when the channel
2530 was created by the router. Affected file silcd/command.c.
2532 * Fixed LIST command (hopefully) to send correct reply
2533 packets. Affected file silcd/command.c.
2535 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2537 * The silc_packet_receive_process now returns FALSE if the
2538 read data was invalid packet, and TRUE if it was ok.
2540 The server now checks that if unauthenticated connection
2541 sends data and its processing fails the server will close
2542 the connection since it could be a malicious flooder.
2544 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2546 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2548 * Make sure the warning about error opening a log file is
2549 printed only once and not everytime it fails (produces
2550 too much useless log). Affected file lib/silcutil/silclog.c.
2552 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2554 * Made the silc_server_daemonise() function more readable.
2555 Affected file silcd/server.c.
2557 * Pid file is now optional, the user may comment it out from
2558 the config file. Removed define SILC_SERVER_PID_FILE, we
2559 don't need a default any longer. Affected file
2560 configure.in.pre, lib/Makefile.am.pre.
2562 * Make some use of the pid file. The server now dies at startup
2563 if it detects a valid pid file on his path. The server would
2564 die anyway in this circumstance, because of the bind() failure.
2565 Affected file silcd/silcd.c.
2567 * No longer compiling lib/dotconf.
2569 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2571 * Fixed JOIN command parsing not to crash. Affected file
2572 lib/silcclient/command.c.
2574 * Fied the NICK_CHANGE notify to add the new client entry
2575 even it is resolved. This removes an <[unknown]> nick
2576 thingy bug in the client. Affected file is
2577 lib/silcclient/client_notify.c.
2579 * Do not try to allocate 0 bytes (efence does not like it)
2580 in lib/silccore/silccomand.c when encoding payload.
2582 * Do not take IRCNICK as nickname in Irssi SILC client since
2583 it is not possible to set nickname before hand connecting
2584 the server (TODO has an entry about adding auto-nicking
2587 * Changed the silc_server_command_pending to check whether
2588 there already exists an pending entry with the specified
2589 command, command identifier and pending callback. This is
2590 to fix IDENTIFY and WHOIS related crashes that may register
2591 multiple pending commands with same identifier. Affected
2592 file silcd/command.c.
2594 * Fixed the server to reconnect to the router even if it
2595 was already reconnecting and EOF was received. This to
2596 fix a possibility that the server wouldn't ever try to
2597 auto-reconnect to the router. Affected file silcd/server.c.
2599 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2601 * Fixed the server's password authentication to use the
2602 length of the locally saved password, and not the one
2603 sent in the packet. Affected file silcd/protocol.c.
2605 * Fixed same password authentication problem in the
2606 Authentication Payload handling routines in
2607 lib/silccore/silcauth.c.
2609 * Yet another password authentication problem fixed with
2610 channel password handling in silcd/command.c.
2612 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2614 * If first character of string in silc_parse_userfqdn is '@'
2615 then do not parse it. Affected file is
2616 lib/silcutil/silcutil.c.
2618 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2620 * Fixed minor bug in IDENTIFY command reply sending, which
2621 caused various weird problems during JOIN when it was
2622 resolving names for users. Affected file silcd/command.c.
2624 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2626 * Fixed the IDENTIFY command reply sending to chech better valid
2627 clients. It was possible to send incomplete list of replies.
2628 Affected file silcd/command.c.
2630 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2632 * Added silc_client_command[s]_[un]register functions now to
2633 dynamically register the commands in client library. Removed
2634 the static table of commands. This allows the client library
2635 to call commands without causing the application to know about
2636 what commands library has called.
2638 Removed the INFO command reply kludge to detect when the command
2639 was called by library. Now library use its own command reply
2640 function for INFO command.
2642 Added function silc_client_command_call to call a command.
2643 Application can use it to call command, not access the structure
2646 Now all commands that are sent by the client library (not
2647 explicitly sent by application) use own command reply functions.
2649 Affected files around lib/silcclient/ and in
2650 irssi/src/silc/core/.
2652 * Fixed the WHOIS command reply sending to chech better valid
2653 clients. It was possible to send incomplete list of replies.
2655 Fixed the WHOIS and IDENTIFY to send the request to router
2656 if normal server did not do it and did not find any results.
2658 Affected file silcd/command.c.
2660 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2662 * Moved the internal data from SilcClient context into its
2663 own file, not accesible to application. Affected files
2664 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2665 and other files in client library.
2667 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2669 * Added doc/examples installation target in Makefile.am.pre.
2672 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2674 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2675 commands the found client entry will be removed from the
2676 cache, after notifying application about the error. Affected
2677 file lib/silcclient/command_reply.c.
2679 * Changed the /MSG to check for exact nickname user gave, and
2680 not let `nick' match `nick@host' if it is only one found. Now,
2681 user must type the exact nickname (like nick@host2) even if
2682 there are no more than one same nicks found. This is to avoid
2683 a possibility of sending nickname to wrong nickname since
2684 `nick' could match `nick@host'. Affected file is
2685 irssi/src/core/silc-servers.c.
2687 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2689 * Do not print "you are now server operator" or similar when
2690 giving /away command. Affected files are
2691 irssi/src/silc/core/client_ops.c, silc-servers.h.
2693 * Made the silc_server_command_pending_error_check to send
2694 the same command reply payload it received back to the
2695 original sender of the command. This way all arguments
2696 that was received by the server will be received by the
2697 client too. Affected file silcd/command.c.
2699 * Added the silc_idcache_add to return the created cache entry
2700 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2702 * Add global clients to expire if they are not on any channel.
2703 This is because normal server will never know if they signoff
2704 if they are not on any channel. The cache expiry will take
2705 case of these entries. This is done by normal servers only.
2706 The affected files are silcd/command_reply.c,
2707 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2709 * If server receives invalid ID notification for WHOIS or
2710 IDENTIFY and the ID exists in the lists, it is removed.
2711 Affected file silcd/command_reply.c.
2713 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2714 in client then client entry that it matches is searched and
2715 the nickname is printed on the screen for user. Affected
2716 file irssi/src/silc/core/client_ops.c.
2718 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2720 * Use cache entry expire time in the LIST command reply to
2721 purge old entries from the cache after the LIST command
2722 reply has been received. This way we don't have non-existent
2723 entries in the cache for too long. Affected file is
2724 silcd/command_reply.c.
2726 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2728 * If we are normal server, and we've not resolved client info
2729 in WHOIS or IDENTIFY from router, and it is global client,
2730 we'll check whether it is on some channel. If it is not
2731 then we cannot be sure about its validity and will resolve it
2732 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2733 file silcd/command.c.
2735 * Search channel by name (if possible) rather than by ID
2736 in IDENTIFY command's command reply. Affected file is
2737 silcd/command_reply.c.
2739 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2741 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2742 Updated specs and implemented it. Affected file silcd/command.c,
2743 silcd/packet_send.c and silcd/packet_receive.c.
2745 * Implemented the <founder auth> payload handling in the JOIN
2746 command. If provided all conditions for channel joining
2747 except requirement to provide correct passphrase can be
2748 overrided by the channel founder. Updated the protocol specs.
2749 Affected file silcd/command.c.
2751 Added support for founder auth in JOIN command in client
2752 library. Fixed the parsing of the JOIN command now to support
2753 all options as they should be. The affected file is
2754 lib/silcclient/command.c.
2756 * Optimized the WHOIS and IDENTIFY commands to send the request
2757 to router only if it includes nicknames or other names. If
2758 they include only IDs then check the local cache first before
2759 routing. Affected file is silcd/command.c.
2761 * Added channels topic announcements. Affected file is
2762 silcd/packet_receive.c and silcd/server.c.
2764 * Fixed the silc_server_send_notify_topic_set to really destine
2765 the packet to channel. Affected file silcd/packet_send.c.
2767 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2768 library. Affected file lib/silcclient/client_notify.c.
2770 * Added UMODE announcements. Affected file silcd/server.c.
2772 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2774 * Memory leak fixes in:
2776 lib/silcutil/silcsockconn.c
2777 lib/silcske/silcske.c
2778 lib/silcske/groups.c
2780 lib/silccrypt/silcpkcs.c
2781 lib/silccore/silccommand.c
2782 lib/silccore/silcidcache.c
2787 * ROBOdoc documented the lib/silcske/groups.h file and a
2788 bit changed the interface for better.
2790 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2792 * Update the client entry context in the ID cache after
2793 nick change. Affected file lib/silcclient/command.c.
2794 Fixes the CUMODE command when regaining founder privileges,
2795 and a little WHOIS problem.
2797 * Fixed silc_net_gethostbyname to correctly call the
2798 inet_ntop. Affected file lib/silcutil/silcnet.c.
2800 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2802 * Added IPv6 support checking to the configure.in.pre, added
2803 also --enable-ipv6 option to override the check. Affected
2804 file configure.in.pre.
2806 * The silc_thread_create now calls the start function
2807 directly if threads support is not compiled in. Removes
2808 ugly #ifdef's from generic code. Affected files are
2809 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2811 * Added silc_net_gethostby[name/addr]_async to asynchronously
2812 resolve. Affected files are lib/silcutil/silcnet.[ch].
2814 * Added support for rendering IPv6 based server, client and
2815 channel IDs. Affected file lib/silcutil/silcutil.c.
2817 * Added support for creating IPv6 based server IDs. Affected
2818 file is silcd/serverid.c.
2820 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2822 * Added silc_net_gethostby[addr/name] into the
2823 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2824 routines. Added silc_net_is_ip[4/6]. Affected file is
2825 lib/silcutil/unix/silcunixnet.c. All routines that take
2826 address as argument now supports both IPv4 and IPv6 addresses.
2828 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2830 * Fixed LIST command reply sending in server. Affected file
2833 * Server now sends the kicker's client ID in the KICK notify
2834 to the kicked client. Affected file silcd/command.c.
2836 * The client library now parses the kickers client ID and
2837 UI displays it. Affected files lib/silcclient/client_notify.c
2838 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2840 * Made all payload parsing function prototypes consistent.
2841 They all take now const unsigned char * and uint32 pair as
2842 the payload data instead of SilcBuffer. Changes all around
2843 the source tree. Other unsigned char* -> const unsigned char*
2844 changes around the tree as well.
2846 * Optimized SFTP client and server packet sending not to
2847 allocate new buffer for each packet but to recycle the
2848 first allocated buffer. Affected files are
2849 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2851 * Optimized the SFTP client to use SilcList instead of
2852 SilcDList for requests, because it is faster. Affected file
2853 is lib/silcsftp/sftp_client.c.
2855 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2856 into lib/silccore/silcid.[ch].
2858 Renamed silcpayload.[ch] into silcargument.[ch].
2860 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2862 * If client entry is deleted with active key agreement
2863 session, abort the session.
2865 The silc_client_abort_key_agreement now calls the completion
2866 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2868 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2871 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2873 * Don't use __restrict in older GCC's. Affected file is
2874 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2876 * silc_net_localhost now attempts to reverse lookup the
2877 IP/hostname. Affected file lib/silcutil/silcnet.c.
2879 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2880 command. It can be used to gain founder privileges at
2881 the same time when joining the channel.
2883 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2884 kicker's client ID as well. Updated protocol specs.
2886 Defined that the server must send SILC_COMMAND_IDENTIFY
2887 command reply with error status to client who sent
2888 private message with invalid client ID.
2890 Updated the protocol specification.
2892 * Added silc_server_send_command_reply to send any
2893 command reply. Affected file silcd/packet_send.[ch].
2895 * Added silc_id_payload_encode_data to encode ID payload
2896 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2898 * The server now send IDENTIFY command reply with error
2899 status if client ID in private message is invalid. Affected
2900 file silcd/packet_receive.c.
2902 * Save the server key file with server's IP address in
2903 the filename instead of hostname. The affected file is
2904 irssi/src/silc/core/client_ops.c.
2906 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2908 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2911 * Added libtool support for compiling shared objects in
2912 lib/silcsim. Affected file configure.in.pre and
2913 lib/silcsim/Makefile.am. Original patch by cras.
2915 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2917 * Pid file configuration, and server's config file fixes
2918 patch by toma. Updated CREDITS file.
2920 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2922 * Fixed silc_client_channel_message to not try to decrypt
2923 the message twice if it resolved the destination client
2924 information. This could cause of dropping one channel
2925 message. Affected file lib/silcclient/client_channel.c.
2927 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2929 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2930 lib/silcclient/client.c. This function is used when the SILC
2931 Client is run under some other scheduler, or event loop or
2932 main loop. On GUI applications, for example this may be
2933 desired to used to run the client under the GUI application's
2934 main loop. Typically the GUI application would register an
2935 idle task that calls this function multiple times in a second
2936 to quickly process the SILC specific data.
2938 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2940 * Fixed silc_server_drop() for dropping the supplementary
2941 groups as well, this could cause a security hole on some
2944 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2946 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2949 * Write PID file after dropping privileges. Added -F option
2950 to run server on foreground. A patch by debolaz.
2951 Affected files silcd/server.c, silcd/silcd.c.
2953 * Fixed MOTD to return the MOTD file server name. Affected
2954 file silcd/command.c.
2956 * Added INFO command reply handling to the Irssi SILC Client.
2957 Affected file irssi/src/silc/core/client_ops.c.
2959 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2961 * Fixed the silc_idcache_list_* routines to really support
2962 the dynamic list. Fixes a crash. Affected file is
2963 lib/silccore/silcidcache.c.
2965 * Fixed the LIST command reply to really call LIST command's
2966 pending callbacks. Affected file silcd/command_reply.c.
2968 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2970 * Update conn->local_entry->nickname after giving NICK
2971 command. Affected file lib/silcclient/command.c.
2973 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2975 * Added the [pid] option to the silcd configuration file
2977 Affected files: serverconfig.[ch] and silcd.c
2979 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2981 * Save fingerprint in WHOIS command reply in server.
2982 Affected file silcd/command_reply.c.
2984 * Fixed NICK commands pending callback registration.
2985 Affected file lib/silcclient/command.c.
2987 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2989 * Use ++server->cmd_ident when sending commands in server,
2990 instead of random number. Affected file silcd/command.c.
2992 * Fixed GETKEY command reply to call actually GETKEY pending
2993 command callbacks. Affected file silcd/command_reply.c.
2995 * A bit stricter check for nicknames. Check for same nickname
2996 in NICK command also. Affected file silcd/command.c.
2998 * Do not call INFO command everytime client ID changes, only
2999 during first connecting. Affected file lib/silcclient/client.c.
3001 * Set the new nickname only after successful command reply for
3002 NICK command is returned by server. Affected file
3003 lib/silcclient/command.c.
3005 * Remove nicknames from nicklist during server_signoff notify.
3006 Should fix /NAMES bit more. The affected file is
3007 irssi/src/silc/core/silc-channels.c.
3009 * Added `fingerprint' field to the SilcIDListData in the
3010 silcd/idlist.h to hold the fingerprint of the client's
3013 Send the fingerprint of the client's public key in WHOIS
3016 Affected files silcd/command.c, and silcd/idlist.[ch].
3018 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3019 create fingerprint from given data.
3021 * Show the fingerprint of the client's public key in WHOIS.
3022 Affected files irssi/src/module-formats.[ch] and
3023 irssi/src/silc/core/client_ops.c.
3025 * Format the multiple same nicknames also during JOIN and
3026 NICK_CHANGE notifys. Affected file is
3027 lib/silcclient/client_notify.c.
3029 * Do not print error on screen for invalid private message
3030 payload since it can come if someone is sending private
3031 messages with wrong key. Affected file
3032 lib/silccore/silcprivate.c.
3034 * Fixed multiple concurrent /PING crash. Affected file
3035 lib/silcclient/command.c.
3037 * Changed the wrong ID encoding. All IP addresses must be
3038 in MSB first order in encoded format. They were encoded
3039 wrong and was in LSB format. Affected files are
3040 silcd/serverid.c, lib/silcutil/silcutil.c.
3042 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3044 * Call the `connect' client operation through the scheduler
3045 in case of error. Affected file lib/silcclient/client.c.
3047 * Call the `failure' client operation even if the error
3048 occurred locally during a protocol. Affected file is
3049 lib/silcclient/protocol.c.
3051 * Added support of sending LIST command to router from normal
3052 server. This way normal server can get list of all channels
3053 in the network too. Fixed the channel list sending in the
3054 server too. Affected files are silcd/command.c, and
3055 silcd/command_reply.[ch].
3057 * Added silc_server_update_channels_by_server and
3058 silc_server_remove_channels_by_server. They are used during
3059 disconnection of primary router and in backup router protocol.
3060 Affected file silcd/server_util.[ch], silcd/server.c and
3061 silcd/server_backup.c.
3063 * Fixed channel adding to global list in IDENTIFY command
3064 reply in server. Affected file silcd/command_reply.c.
3066 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3068 * If the incoming packet type is REKEY or REKEY_DONE process
3069 that packet always synchronously. Fixes yet another MAC
3070 failed error on slow (dialup) connections. Affected file
3071 lib/silcclient/client.c and silcd/server.c.
3073 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3075 * Call check_version SKE callback for initiator too. Affected
3076 file lib/silcske/silcske.c.
3078 * Implemented fix for security hole found in the SKE that was
3079 fixed in the specification few days back; the initiator's
3080 public key is now added to the HASH value computation.
3081 Added backwards support for the old way of doing it too, for
3082 old clients and old servers. Affected file is
3083 lib/silcske/silcske.c.
3085 * Enabled mutual authentication by default in SKE. If initiator
3086 is not providing mutual authentication the responder will
3087 force it. This will provide the proof of posession of the
3088 private key for responder. The affected files are
3089 lib/silcclient/protocol.c and silcd/protocol.c.
3091 * Do not cache anymore the server's public key during SKE.
3092 We do mutual authentication so the proof of posession of
3093 private key is done, and if the server is authenticated in
3094 conn auth protocol with public key we must have the public
3095 key already. Affected file silcd/protocol.c.
3097 * Added new global debug variable: silc_debug_hexdump. If
3098 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3099 file lib/silcutil/silclog.[ch].
3101 * Fixed compilation warning due to char * -> const char *.
3102 Affected files lib/silcutil/silcnet.h, and
3103 lib/silccore/silcauth.[ch].
3105 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3107 * Fixed CMODE command when new channel key was created. If
3108 the creation failed the old key was removed. Next time giving
3109 same command would crash the server since the old key was
3110 freed already. Affected file silcd/command.c.
3112 * Fixed the silc_server_announce_get_channels to not crash
3113 on reconnect. Affected file silcd/server.c.
3115 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3117 * Added silc_log_set_debug_string function to set a regex
3118 string to match for debug output. Only the function names,
3119 or filenames matching the given debug string is actually
3120 printed. This way it is possible to filter out those debug
3121 strings that user is not interested in.
3123 Fixed a bug in silc_string_regexify.
3125 Affected files lib/silcutil/silclog.[ch], and
3126 lib/silcutil/unix/silcunixutil.c.
3128 * Changed the -d options in both server and Irssi SILC client
3129 to take the debug string as argument. Affected files
3130 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3132 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3134 * Added silc_hash_babbleprint to create a Bubble Babble
3135 Encoded fingerprint. The encoding is developed by Antti
3136 Huima (draft-huima-babble-01.txt), and it creates human
3137 readable strings out of binary data. Affected file
3138 lib/silccrypt/silchash.[ch].
3140 * Print the babble print now in addition of fingerprint as well
3141 in Irssi SILC client. Affected files are
3142 irssi/src/fe-common/silc/module-formats.[ch],
3143 irssi/src/fe-common/silc/core/client_ops.c.
3145 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3147 * Fixed a security problem found in SKE. The initiator's
3148 public key too is now added to the HASH hash value creation
3149 which is signed by the responder to create the SIGN value.
3150 This will prevent anyone in the middle to lie to the responder
3151 about the initiator's public key. If this is done now, the
3152 man in the middle will get caught. Updated the protocol
3155 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>

3191 * Added silc_pkcs_public_key_compare to compare two
3192 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3194 * Check that the client who set the founder mode on the
3195 channel is the same client that is giving the founder
3196 mode to itself. It is done by comparing the saved public
3197 key (it is saved even in the authentication is passphrase).

3205 * Process the DISCONNECT packet through scheduler in the
3206 client library. Affected file lib/silcclient/client.c.
3208 * Fixed the silc_client_packet_parse to not to increase
3209 the packet sequence number if the conn->sock and the
3210 current socket connection is not same. This can happen
3211 for example during key agreement when the conn includes
3212 multiple socket connections (listeners). Affected file
3213 lib/silcclient/client.c.
3215 * The sender of the file transfer request now provides also
3216 the pointer (listener) for the key exchange protocol. If
3217 the listener cannot be created then it sends empty key
3218 agreement and lets the receiver provide the listener.
3220 Added `local_ip' and `local_port' arguments to the
3221 silc_client_file_send. If they are provided they are used,
3222 if not then it will attempt to find local IP address, if
3223 not found or bind fails then the remote client will provide
3226 Affected files are lib/silcclient/client_ftp.c and
3227 lib/silcclient/silcapi.h.

3236 of the client's public key (if the proof of posession of the
3237 corresponding private key is verified by the server).
3238 Updated to the protocol specification.
3240 * Added support of receiving the client's public key's
3241 fingerprint in command reply in client library. Affected
3242 file is lib/silcclient/command_reply.c, and
3243 lib/silcclient/idlist.[ch].

3302 preserve the WHOWAS info for the client. Affected file
3303 silcd/server_util.c.
3305 * Fixed SERVER_SIGNOFF notify handling in the server. The
3306 server is now able to process incoming SERVER_SIGNOFF notify
3307 for a server that it doesn't even know about. It will remove
3308 the clients provided in the notify. Affected file
3309 silcd/packet_receive.c.
3311 * Check for partial packet in data queue after every packet that
3312 was found from the queue. Return and wait for more data if
3313 there is partial data in queue. Affected file is
3314 lib/silccore/silcpacket.c.
3316 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

3331 irssi/src/fe-common/silc/module-formats.[ch].
3333 * Wrote a help file for FILE command.
3335 * Added silc_rng_global_get_byte_fast to get not-so-secure
3336 random data as fast as possible. Random data is read from
3337 /dev/urandom if available and from the SILC RNG if not
3338 available. It is used in padding generation. Affected file
3339 lib/silccrypt/silcrng.[ch].
3341 * All packets in client library are now processed synchronously.
3342 Optimized packet processing a lot. Affected file
3343 lib/silcclient/client.c.
3345 * All server connection packets are processing synchronously
3346 now in server, to optimize packet processing. Affected file
3349 * Include files are installed now only in Toolkit distribution
3350 if make install is given. Affected files: all Makefile.am's.
3352 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3354 * Assure that silc_client_notify_by_server_resolve does not
3355 resolve the client information multiple times. If it cannot
3356 be found by the first it cannot be found at all. Affected
3357 file lib/silcclient/client_notify.c.
3359 * Fixed WHOWAS command reply calling. Affected file
3360 lib/silcclient/command_reply.c.
3362 * Removed all references to silc_idlist_get_client from the
3363 Irssi SILC client since that call is internal call used by
3364 the library. The Irssi SILC client will use now client
3365 retrieval functions found in silcapi.h.
3367 * Fixed a bug in resolving nickname info before sending
3368 private message. It used freed memory. Affected file
3369 irssi/src/silc/core/silc-servers.c.

3390 * Added silc_net_localip to return local host's IP address.
3391 Affected file lib/silcutil/silcnet.[ch].
3393 * If key exchange or rekey protocol is active for a connection
3394 parse all packets syncronously since there might be packets
3395 in packet queue that we are not able to process without first
3396 processing packets before them. Affected file silcd/server,
3397 lib/silcclient/client.c.
3399 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3400 whether library should continue processing the packet.
3401 Affected file lib/silccore/silcpacket.h.
3403 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

3447 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3448 is incomplete and is being resolved, it won't be resolved
3451 Make sure also that USERS command reply does not resolve
3452 twice information. Affected file is
3453 lib/silcclient/command_reply.c.
3455 Make sure that silc_client_get_clients_by_list does not
3456 resolve twice same information.
3458 * Check for valid client->id in the silc_server_free_client_data.
3459 Affected file silcd/server.c.
3461 * Fixed /GETKEY nick@server not to crash if the server entry
3462 is not found. Affected file lib/silcclient/command.c.

3474 * Call the silc_server_udpate_servers_by_server in the
3475 primary router that comes back online in the backup resuming
3476 protocol. Otherwise it routes packets wrong. Affected file
3477 silcd/server_util.[ch], silcd/server_backup.c.
3479 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3481 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3482 lib/silcutil/silcbuffmt.[ch].
3484 * Redefined the SILC packet header to include the padding
3485 length. Affected file lib/silccore/silcpacket.[ch].
3487 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3488 length for maximum padding up to 128 bytes). Affected
3489 file lib/silccore/silcpacket.h.
3491 * Removed all backwards support for old 0.5.x MAC thingies.
3492 The SILC packet header change makes it impossible to be
3493 backwards compatible.
3495 * Send the ENDING packet with timeout in the backup resuming
3496 protocol. This is to assure that all routers has connected
3497 to the primary router. Affected file silcd/server_backup.c.
3499 * Changed the RNG to take the first IV from random data. It
3500 used to take it from zero actually. Changed the RNG also
3501 to use /dev/urandom during session. /dev/random is used
3502 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3504 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3506 * Changed the SILC packet header to have the first two bytes
3507 (the packet length) encrypted. Affected files aroung the
3508 code tree, lib/silccore/silcpacket.[ch]. Removed the
3509 SilcPacketCheckDecrypt callback. It is not needed anymore
3510 since the silc_packet_receive_process will determine now
3511 whether the packet is normal or special.
3513 * Implemented the unidirectional MAC keys. Affected files
3514 lib/silcske/silcske.c, silcd/protocol.c and
3515 lib/silcclient/protocol.c.

3522 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3524 * Allow backup router to announce servers. All servers
3525 announced by backup router are added to the global list
3526 automatically. Update hte server's socket to our primary
3527 router also when backup router announces a server.
3528 Affected file silcd/packet_receive.c.
3530 * Do not update the client->router in the function
3531 silc_server_udpate_clients_by_server if the client is on
3532 global list. We might fail to find any specific server
3533 for locally connected clients and local cell clients. They
3534 should still use the `from' and not `to' as client->router.
3535 This fixes backup router resuming protocol. Affected file
3536 silcd/server_util.c.
3538 * Decrease channel statistics count only if the channel
3539 deletion worked. Affected files are silcd/server.c and
3540 silcd/server_util.c.
3542 * Added silc_server_update_servers_by_server to update origin
3543 of all server entries. Used during backup router protocol.

3552 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3554 * Assure that router cannot reroute the same channel message
3555 to the sender. Affected file silcd/packet_receive.c.
3557 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3559 * Made better checks that the channel message is not sent
3560 to the router it came from. Affected file is
3561 silcd/packet_send.c. Fixed memory leak too.
3563 * Announce informations for incoming router connection, but
3564 only after checking if it is replaced by backup router.
3565 Affected file silcd/packet_receive.c.
3567 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3570 router environment. Affected file silcd/server_backup.c.
3572 * Route packet only to one router in the function
3573 silc_server_packet_send_to_channel. Affected file is
3574 silcd/packet_send.c.
3576 * Fixed silc_server_send_notify_dest to set the broadcast
3577 flag. Fixed the silc_server_send_notify_topic to actually
3578 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3579 Affected file silcd/packet_send.c.
3581 * Changed the SFTP Filesystem interface. Changed the
3582 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3583 the filesystem operation function. The SilcSFTPFilesystem
3584 is now a context that is allocated by all filesystem allocation
3585 functions and it already includes the operations structure
3586 and filesystem specific context. It is given as argument
3587 now to the silc_sftp_server_start. This made the interface
3588 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3589 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3591 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3593 * Changed the backup router adding and getting interfaces
3594 in the server. The router that will be replaced by the
3595 specified backup router is now sent as argument. Affected
3596 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3599 * Added silc_net_addr2bin_ne to return the binary form of
3600 the IP address in network byte order. Affected files

3616 * Wrote the definition of the backup resuming protocol to the
3617 protocol specification.
3619 * Removed one redundant channel key generation from normal
3620 server during joining procedure. Removed one redundant
3621 channel key sending from server to router during joining
3622 procedure. Affected file silcd/command.c.
3624 * Made minor bugfixes to the backup router resuming protocol.
3625 Affected file silcd/server_backup.c, server.c.

3648 send any data. Affected file lib/silcclient/client.c.
3650 * Implemented the backup router support when the primary router
3651 goes down. The servers and routers can now use the backup
3652 router as new primary router without loosing connectivity.
3654 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3656 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3657 in the server to indicate disabled entry. All data read
3658 from the connection will be ignored and no data is sent
3659 for entry that is disabled. Affected files are
3660 silcd/idlist.h, silcd/server.c.
3662 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

3670 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3673 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3675 * Implemented the SFTP (SSH File Transfer Protocol) to the
3676 lib/silcsftp. It includes SFTP client and SFTP server
3679 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3681 * Moved lib/silccore/silcprotocol.[ch] to the
3682 lib/silcutil library.
3684 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3685 take variable argument list pointer as argument. Affected
3686 file lib/silcutil/silcbuffmt.[ch].
3688 * Added silc_buffer_set function that is used to set data
3689 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3690 Affected file lib/silcutil/silcbuffer.h.
3692 * Changed various routines in the core library to use the new
3693 silc_buffer_set instead of allocating new buffer only for
3696 * Added 64-bit value formatting and unformatting support to the
3697 silc_buffer_[un]format routines. Affected file is
3698 lib/silcutil/silcbuffmt.[ch].
3700 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3701 to includes/bitmove.h.
3703 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3705 * Fixed channel user mode saving in client library. Affected
3706 file lib/silcclient/command[_reply].c.
3708 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3710 * Defined the file transfer to the SILC Protocol. Added
3711 new packet type SILC_PACKET_FTP and defined File Transfer
3712 Payload. The mandatory file transfer protocol is SFTP
3713 (SSH File Transfer Protocol). Affected file in addition
3714 of the internet draft is lib/silccore/silcpacket.h.
3716 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3717 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3718 is used as part of backup router protocol when the primary
3719 router of the cell is back online and wishes to resume
3720 the position as primary router.
3722 * Redefined the MAC generation keys in the protocol. The
3723 same key is not used anymore in both direction. Both
3724 direction will now use different keys for sending and
3725 receiving. This fixes a potential security flaw. This
3726 change causes incompatibilities in the protocol.
3728 * Redefined also the MAC computation from the packet.
3729 An packet sequence number is now added to the MAC
3730 computation. This prevents possible replay attacks against
3731 the protocol. This change too causes incompatibilities
3734 Added `sequence' field to the SilcPacketContext to hold
3735 the current sequence number for the packet.
3737 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3739 * Added `created' field to the SilcIDListData in the file
3740 silcd/idlist.h to indicate the time when the entry was
3743 * Added `created' field to the SilcChannelEntry too. Affected
3744 file silcd/idlist.h.
3746 * Added `creation_time' aguments to all the announcement functions
3747 in the server. If it is provided then only the entries that
3748 was created after the provided time frame are actually
3749 announced. Affected file silcd/server.[ch].
3751 * The protocol says that the Channel ID's IP address must be
3752 based on the router's IP address. Added check for this in
3753 the silc_server_new_channel when processing incoming New Channel
3754 Payload. Affected file silcd/packet_receive.c.
3756 * Print out the correct version with --version in SILC client.
3757 Affected file irssi/src/silc/core/silc-core.c.
3759 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3761 * Fixed WHOWAS command to check for completnes of the client
3762 entry always, not just when the command is coming from client.
3763 Affected file silcd/command.c.
3765 * Added new function silc_server_packet_queue_purge to purge the
3766 outgoing data queue to the network. After the function returns
3767 it is guaranteed that the outgoing packet queue is empty.
3768 Affected file silcd/packet_send.[ch].
3770 * Purge the outgoing packet queue in the rekey protocol's final
3771 callback to assure that all rekey packets go to the network
3772 before quitting the protocol. Affected file silcd/server.c.
3774 * Added silc_client_packet_queue_parse as similar function as
3775 in server to the client library. The affected file is
3776 lib/silcclient/client.c.
3778 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3780 * Splitted silcd/server.c and created silcd/server_util.[ch]
3781 for utility functions.
3783 * Added new socket flag SILC_SF_DISABLED to indicate that the
3784 connection is open but nothing can be sent to or received from
3785 the connection. Affected file lib/silcutil/silsockconn.[ch].
3786 The checking for disabled socket is checked in the low level
3787 silc_socket_write and silc_socket_read functions.
3789 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3791 * Allow only nicknames and channel names that fits into the
3792 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3794 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3796 * When processing JOIN command reply in server check that if
3797 the channel exists in our global list we'll move it the local
3798 list. Affected file silcd/command_reply.c.
3800 * Fixed the check whether client is joined on the channel already
3801 in JOIN command. Affected file lib/silcclient/command.c.
3803 * Fixed the JOIN command reply to check whether the channel
3804 already exists. Affected file lib/silcclient/command_reply.c.
3806 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3808 * Added silc_ske_status_string to map the SKE error numbers
3809 to readable strings. The affected files are
3810 lib/silcske/silcske[_status].[ch].
3812 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3814 * Do not show the private channels on the WHOIS channel list
3815 as it is not allowed by the protocol. The affected file is
3818 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3820 * Assure that the packet length digged from the actual packet
3821 is something sensible in the silc_packet_decrypt_rest_special
3822 in lib/silccrypt/silcpacket.c.
3824 * Free and NULL the allocated pointer in silc_hmac_alloc if
3825 the HMAC allocation fails. The affected file is
3826 lib/silccrypt/silchmac.c.
3828 * Print the selected security properties to the log files in
3829 the server. Affected file silcd/protocol.c.
3831 * Add SKE's reference counter even if calling the completion
3832 callback manually. Otherwise it goes negative, although it
3833 does not cause any problems. The affected file is
3834 lib/silcske/silcske.c.
3836 * Remove the client entry with short timeout after giving the
3837 KILL command. Affected file lib/silcclient/command.c.
3839 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3840 case all found clients are already disconnected (WHOWAS would
3841 found them) in the server. Affected file silcd/command.c.
3843 * Update the last_receive (time of last data received) to be
3844 updated only when received private or channel message so that
3845 the idle time showed in WHOIS makes more sense.
3847 * Added boolean field `valid' in to the SilcClientEntry in the
3848 client library to indicate whether the entry is valid or not.
3849 This fixes the nickname change bug on channel when changing
3850 the nickname to be same than the old (like nick to Nick) the
3851 nickname formatter doesn't set the new nick anymore to Nick@host.
3852 Affected file lib/silcclient/idlist.[ch].
3854 * Now actually fixed the nickname changing on disconnection.
3855 Added new function silc_change_nick to the Irssi SILC Client.
3856 Affected file irssi/src/silc/core/client_ops.c,
3857 irssi/src/silc/core/silc-nicklist.[ch].
3859 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3861 * Check that the public key exists in the GETKEY command before
3862 trying to encode it. Affected file silcd/command.c.
3864 * Print some notifications on received public keys with GETKEY
3865 command in the Irssi SILC Client. Affected files are
3866 irssi/src/fe-common/silc/module-formats.[ch],
3867 irssi/src/silc/core/client_ops.c.
3869 * Use IDENTIFY command to resolve the server information in the
3870 GETKEY command instead of INFO command. Affected file
3871 lib/silcclient/command.c.
3873 * All command reply functions in the client library now calls
3874 the pending command reply callbacks even if an error has
3875 occurred. The server has done this a long time and now it was
3876 time to move the client library to this as well. Now all
3877 errors can be delivered back to the pending command reply
3878 callbacks if necessary. Affected files are
3879 lib/silcclient/command[_reply].[ch].
3881 * Change the nickname on disconnection back to the username
3882 because in reconnect the server will enforce it to it anyway.
3883 Affected file irssi/src/silc/core/silc-servers.c.
3885 * Fixed a config file parsing bug in the Irssi SILC client.
3886 Affected file irssi/src/silc/core/clientconfig.c.
3888 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3890 * When printing the channel mode on JOIN, verify that the
3891 channel key and channel's HMAC are valid. Affected file
3892 irssi/src/silc/core/client_ops.c.
3894 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3896 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3897 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3898 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3900 * Removed channel key rekey task deleting from the function
3901 silc_server_save_channel_key. Affected file silcd/server.c.
3902 Added explicit timeout task context instead that is used to
3903 delete the task if we are registering a new task before the
3904 new task has elapsed.
3906 * When channel key rekey occurs the client library now saves
3907 the old channel key for a short period of time (10 seconds) and
3908 is able to use it in case some is still sending channel
3909 messages encrypted with the old key after the rekey. Affected
3910 file lib/silcclient/[idlist.h|client_channel.c].
3912 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3914 * Added check to the silc_server_new_id_real to not accept
3915 new ID if it is the sender's own ID. Affected file is
3916 silcd/packet_receive.c.
3918 * Assure that we do not announce ourself or the one we've
3919 sending our announcements when we're router and are announcing
3920 servers to our primary router. Affected file silcd/server.c.
3922 * Fixed silc_server_command_identify_check_client to assemble
3923 correct WHOIS packet. It send corrupted WHOIS packet and
3924 caused problem with router to router connections. Affected
3925 file silcd/command.c.
3927 Fixed also silc_server_command_whois_check the same way
3928 as for the IDENTIFY command.
3930 * Added new SilcIDListStatus to the server in the SilcIDListData
3931 structure. The status now includes the current status of
3932 the entry (like registered, resolved etc.). Affected file
3933 silcd/idlist.[ch]. Defined a bunch of different status types
3934 as well. This replaced the old boolean registered field as well.
3936 Added resolve_cmd_ident field to the SilcClientEntry structure
3937 too so that if the entry is for example being resolved so
3938 another command may attach to the same pending command reply
3939 without requiring to resolve the same entry again. This concept
3940 should optimize the WHOIS and the IDENTIFY resolving under
3941 heavy load by taking away unnecessary resolving for entries
3942 that are being resolved already.
3944 Added support for adding multiple pending commands for one
3945 command idenfier. Affected file silcd/command[_reply].[ch].
3947 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3948 before deleting the data. Otherwise the hash table will have
3949 freed data in comparison functions. Affected file is
3950 silcd/command_reply.c.
3952 * Fixed silc_idlist_replace_client_id to add the new entry to
3953 the cache with NULL nickname. Otherwise there will be invalid
3954 memory as the nickname after the nickname is freed. Affected
3955 file silcd/packet_receive.c.
3957 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3958 saved into wrong slots because the previous number of entries
3959 was not taken into account. Affected file silcd/idlist.c.
3960 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3962 * If we are router and we receive JOIN notify to a channel that
3963 does not have any users then notified client is marked as the
3964 channel founder, as it is it. The affected file is
3965 silcd/packet_receive.c
3967 * Added to the extended hash table API's table_del_*ext functions
3968 the destructor as argument too, so that the caller can decide
3969 which destructor to use or whether to use destructor at all.
3970 Affected file lib/silcutil/silchashtable.[ch].
3972 * Fixed ID Cache purging. It actually deleted the entries from
3973 the hash table after the data was freed. The hash table ended
3974 up comparing freed memory. The affected file is
3975 lib/silccore/silcidcache.c.
3977 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3979 * Fixed Irssi SILC client's KILL command's HELP syntax.
3981 * The USERS command now resolves the detailed user information
3982 if the userinfo field is missing. Affected file is
3983 lib/silcclient/command_reply.c.
3985 * Do not print error in silc_file_read if the read file does
3986 not exist. Just silently return NULL. Affected file is
3987 lib/silcutil/silcutil.c.
3989 * Fixed the silc_log_output to not wine about NULL filename
3990 and to not create some bogus " " filename. Affected file is
3991 lib/silcutil/silclog.c.
3993 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3995 * Fixed various printing bugs on the user interface in the
3996 Irssi SILC Client. Minor changes that were forgotten from
3999 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4001 * Fixed the configure.in.pre and the compilation and distribution
4002 environment to support the new autoconf 2.52. That version is
4003 now required to compile the CVS trunk.
4005 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4007 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4008 to generally parse user@fqdn format strings. Affected file
4009 lib/silcutil/silcutil.c.
4011 * Added nickname_format and nickname_force_format fields to the
4012 SilcClientParams structure. The first one defines the format
4013 for the nicknames that the library will enforce if the receives
4014 multiple same nicknames. The second one is boolean value and
4015 can be used to force the library to always enforce the format
4016 to the nicknames regardles whether there are multiple nicknames
4017 or not. This configurable formatting was employed to flexibly
4018 support accessing multiple nicknames from the user interface.
4019 The userinterface can now set the nicknames to what ever format
4020 they prefer. Affected file lib/silcclient/silcapi.h.
4022 Added function silc_client_nickname_format to the file
4023 lib/silcclient/idlist.c. It performs the nickname formatting.
4025 Added new field `hostname´ to the SilcClientEntry context.
4026 It holds the hostname of the client. Affected file is
4027 lib/silcclient/idlist.h.
4029 * Irssi SILC Client sets the nicknames in nick@hostn format.
4030 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4031 irssi/src/silc/core/silc-core.c.
4033 The WHOIS printing now also shows both the real nickname and
4034 the formatted nickname so that user knows how to access the
4035 user if there are multiple same nicknames cached. Affected
4036 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4037 printing formatting too to take the hostname now as a separate
4038 argument. The Affected file is
4039 irssi/src/fe-common/silc/modules-formats.[ch].
4041 * Changed the silc_client_get_clients_local to accept the formatted
4042 nickname as argument. It accepts the real nickname too but the
4043 formatted nickname can be used to find the true entry from
4044 multiple entries. Affected file lib/silcclient/silcapi.h and
4045 lib/silcclient/idlist.c.
4047 * Added nickname_format_parse field to the SilcClientParams.
4048 It is a callback function provided by the application to parse
4049 the nickname out of the formatted nickname string. The library
4050 calls it to get the nickname from the formatted string. Since
4051 the application generally knows better the format of the nickname
4052 string it parses it instead of the library, even though library
4053 encodes the formatted string. If the callback function is not
4054 provided then the library will use the string as is. The
4055 affected file is lib/silcclient/silcapi.h.
4057 * All the nickname strings passed to the client library in
4058 commands are now expected to be formatted nickname strings.
4059 If the command does not support the formatted nickname string
4060 it will assume that the sent string is the actual nickname.
4061 Affected file lib/silcclient/command.c.
4063 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4065 * Added public key authentication support to OPER and SILCOPER
4066 commands in the client library. Affected file is
4067 lib/silcclient/command.c.
4069 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4071 * Changed the get_auth_methdod client operation to be asynchronous.
4072 It can be async if the application resolves the authentication
4073 method from the server during the negotiation. Added new
4074 SilcGetAuthMeth completion callback that the application will
4075 call after resolving the authentication method.
4077 Added function silc_client_request_authentication_method that
4078 the application can use to resolve the authentication method
4079 from the server. Added also SilcConnectionAuthRequest callback
4080 that the library will call after the server has replied. The
4081 application can call this function if it does not know the
4082 current authentication method.
4084 Affected files are lib/silcclient/client.c and
4085 lib/silcclient/silcapi.h.
4087 * The Irssi SILC client now automatically resolves the authentication
4088 method incase any configuration information is not present (and
4089 currently there never is). The affected file is
4090 irssi/src/silc/core/client_ops.c.
4092 * Fixed public key authentication from the client library.
4093 Affected file lib/silcclient/protocol.c. Changed also the
4094 protocol specification about the public key authentication in
4095 the connection authentication protocol. The actual data to be
4096 signed is now computed with a hash function before signing.
4098 * Fixed the public key authentication from the server as well.
4099 Affected file silcd/protocol.c.
4101 * Removed the mlock()'s from the memory allocation routines.
4102 Affected file lib/silcutil/silcmemory.c. The ./configure does
4103 not check anymore for the mlock(). Affected file is
4106 * Fixed USERS command in server to allow the execution of the
4107 command for private and secret channels if the client sending
4108 the command is on the channel. Affected file silcd/command.c.
4110 * Fixed silc_client_get_clients_local to return the clients
4111 count correctly. It could return wrong value. Affected file
4112 lib/silcclient/idlist.c.
4114 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4116 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4117 types. The assembler optimizations seemed not to like 64-bit
4118 data types. The assmebler optimizations thus are now enabled
4119 also for BSD systems as opposed to only enable them for Linux.
4121 * Do not check for threads at all on BSD systems. Affected
4122 file configure.in.pre.
4124 * Removed -n and -h options from the Irssi SILC Client since
4125 they are not used in silc.
4127 * Fixed the prime generation to assure that the first digit
4128 of the generated random number is not zero since our conversion
4129 routines does not like number strings that starts with zero
4130 digit. If zero digit is seen the random number is regenerated.
4131 This caused some corrupted RSA keys when the zero first digit
4132 was met. Affected file lib/silcmath/silcprimegen.c.
4134 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4136 * Fixed WIN32 configuration in the ./configure script.
4137 Fixed to include xti.h on environments that has it.
4138 Patches by Carsten Ilchmann and andrew.
4140 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4142 * Changed the silc_id_create_client_id to be collision
4143 resistant. It is now assured that there cannot be created
4144 two same client ID's. I suspect that some weird bugs in
4145 the server were actually caused by duplicate Client IDs.
4146 Affected file silcd/serverid.[ch]. A router receiving
4147 new ID now also assures and informs the sending server
4148 if the ID caused collision.
4150 * Changed the silc_id_create_channel_id to also assure that
4151 there are no collisions.
4153 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4155 * Statement about ignoring the Mutual Authentication flag when
4156 performing rekey with PFS was a bit misleading. It is ignored
4157 if it was set in the initial negotiation, it cannot be even
4158 set in the rekey. Fixed in the ke-auth draft. Started the
4159 new versions of the protocol drafts in the doc/.
4161 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4163 * Fixed a bug in silc_client_command_identify_save when saving
4164 new channel information. The channel name was no duplicated
4165 and caused crash on exit. Affected file is
4166 lib/silcclient/command_reply.c.
4168 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4170 * Fixed the getkey command handling in the server. Send just
4171 empty OK reply to the sender if the key could not be fetched
4172 (but everything else was ok, like the key just was not available).
4173 Changed the public key parameter to optional in the protocol
4174 specs so that empty OK reply can be sent. Affected file
4177 Added a message to Irssi SILC client to tell to user if the
4178 server did not return a public key.
4180 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4182 * Fixed a channel key regeneration bug. It registered new
4183 timeout tasks exponentially until all system resources were
4184 used. Affected file silcd/server.c.
4186 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4188 * Added the SILC Document generator to the scripts/silcdoc.
4189 It can be used to generate the Toolkit Reference Manual out
4190 of the source tree. Internally it will also use the RoboDoc
4191 generator now imported in util/robodoc.
4193 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4195 * Added couple of return's in rekey protocol if error orccurred
4196 during the protocol. The execution must be terminated.
4197 Affected file silcd/protocol.c. Also, terminate the protocol
4198 always with timeout.
4200 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4202 * The client's Client ID was created initally from the wrong
4203 nickname (it could have been in format nick@host) in the
4204 silc_server_new_client. Affected file silcd/packet_receive.c
4206 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4208 * Added some SILC_LOG_ERROR's to various error conditions
4209 if client could not be added to ID cache. Affected files
4210 silcd/packet_receive.c and silcd/server.c.
4212 * When client's sock->user_data is freed, NULL also the
4213 client->router and client->connection pointers. Added check
4214 for these pointers being NULL to various places around the
4215 code. Affected file silcd/server.c.
4217 * Added client->data.registered == TRUE checks to various
4218 places around the code to assure that unregistered client's
4219 are not handled when it is not allowed. Affected file
4222 * Added `bool registered' fields to all
4223 silc_idlist_[server|client]_get_* routines to indicate whether
4224 the fetched client needs to be registered or not. Affected
4225 file silcd/idlist.[ch].
4227 * Add your own entry as registered to the ID cache in the
4228 server. Affected file server.c.
4230 * Fixed a bug in silc_server_new_server. The SilcServer was
4231 set as the new server's context instead of SilcServerEntry.
4232 This naturally caused some weird bugs.
4234 * Added "updated" field the SilcChannelEntry which indicates
4235 the time since the channel entry was last accessed. This
4236 can be used to determine whether it is necessary to
4237 announce the channel after backup resuming protocol.
4238 Affected files silcd/idlist.[ch].
4240 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4242 * Do not delete the channel rekey task when adding it
4243 for in silc_server_create_channel_key.
4245 * Changed the silc_server_create_channel_key to return
4246 TRUE or FALSE to indicate the success of the channel key
4249 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4251 * Fixed MSVC++ project files and added missing files to

4254 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4256 * Do not add TCP_NODELAY flag if the operating system
4257 does not have it defined. Affected files are
4258 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4260 * Fixed buffer overflow from Irssi SILC Client. Affected
4261 file irssi/src/fe-common/core/themes.c.
4263 * Fixed double free in client library in the file
4264 lib/silcclient/client.c when disconnecting from server.
4266 * Applied double free patch from cras to Irssi SILC client.
4267 Affected files irssi/src/core/[modules/expandos].c
4269 * Fixed the disconnection handling to Irssi SILC Client.
4270 The application must call silc_client_close_connection
4271 in ops->connect client operation in case of failure of
4272 the connection. Affected file is
4273 irssi/src/silc/core/client_ops.c.
4275 * Do not set sock->protocol to NULL in the function
4276 silc_client_close_connection after executing the protocol's
4277 final callback since the sock might not be valid anymore.
4278 Affected file lib/silcclient/client.c.
4280 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4282 * Do not enable SILC_THREADS if the linking with libpthread
4283 did not happen. Affected file configure.in.pre.
4285 * Added notion to protocol specification that server must
4286 verify the sent authentication payload with CMODE when
4287 setting the channel founder key. Implemented it to the
4288 server. Affected file silcd/command.c.
4290 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4292 * Added _EXTRA_DIST SILC distribution variable to the
4293 distributions file. It is used to conditionally add extra
4294 files or directories to the specific distribution. Affected
4295 files ./prepare, Makefile.am.pre and distributions.
4297 Removed the `_' from the start of the distribution names.
4300 * Added README.WIN32 for instructions to compile the Toolkit
4303 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4305 * Fixed a double free in disconnection in the server. Affected
4306 file is silcd/server.c.
4308 * Fixed the lib/silcske/groups.c to work now also with GMP
4309 MP library. The string conversion did not work when using
4310 specific base and the base is indicated in the string as well.
4312 * Created win32/ directory which now includes MSVC++ specific
4313 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4314 It will appear only in the toolkit distribution
4316 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4318 * Changed the key material distribution function in case when
4319 the hash output is too short. The data is now concatenated
4320 a bit differently than it used to. Made the change to the
4321 SKE protocol specification.
4323 * Added better GMP detection to configure.in.pre. A patch
4326 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4328 * Fixed a minor bug in SKE that might cause some problem on
4329 some platforms. Affected file lib/silcske/silcske.c.
4331 * Added the cookie checking for initiator in the SKE. It checks
4332 that the responder returns the sent cookie unmodified. The
4333 affected file is lib/silcske/silcske.c. Added new SKE
4334 error type INVALID_COOKIE that can be sent during the
4335 negotiation. Fixed some memory leaks as well.
4337 * Added the "invalid cookie" error message to Irssi SILC client's
4340 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4342 * Added `task_max' field to the SilcClientParams to indicate
4343 the maximum tasks the scheduler can handle. If set to zero,
4344 default values are used. Affected file lib/silcclient/silcapi.h.
4346 * Fixed memory leaks in silc_client_close_connection. Affected
4347 file lib/silcclient/client.c.
4349 * Added silc_client_del_client_entry to client library to free
4350 all memory of given client entry. Affected file is
4351 lib/silcclient/idlist.[ch].
4353 * Added new functions silc_client_del_channel and
4354 silc_client_del_server to delete channel and server entries.
4355 Affected file lib/silcclient/[silcapi.h/idlist.c].
4357 * Removed silc_client_del_client_by_id from silcapi.h.
4359 * Fixed the INFO command to return the server's own info
4360 correctly when querying by Server ID. Affected file is
4363 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4365 * Removed the non-blocking settings in WIN32 code in the
4366 silc_sock_[read/write] and added SleepEx instead. Affected
4367 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4368 of input data is now checked with FIONREAD and ioctlsocket.
4370 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4372 * Call silc_schedule_task_del_by_context in the
4373 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4374 Affected file lib/silccore/silcprotocol.c.
4376 * Call silc_protocol_cancel for active protocols in the
4377 silc_server_close_connection if the funtion
4378 silc_server_free_sock_user_data has not been called.
4379 Affected file silcd/server.c.
4381 * Generic tasks cannot be deleted using the del_by_fd
4382 task deleting function since generic tasks does not match
4383 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4385 * Added a notion to SILCOPER help file that the SILCOPER works
4386 only on router server, not on normal server.
4388 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4390 * Added for WIN32 support for the new scheduler as well.
4391 Affected file lib/silcutil/win32/silcwin32schedule.c.
4393 * Fixed the SHA1 implementation to work on various platforms.
4395 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4397 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4398 API. It is part of the scheduler now. Everything else is
4399 as previously but some functions has changed their names.
4400 Checkout the lib/silcutil/silcschedule.h for the interface.
4401 Updated all applications to use the new interface. Affected
4402 files are lib/silcutil/silcschedule.[ch].
4404 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4406 * Found a bug in the SKE implementation. The HASH value,
4407 specified by the protocol, was not computed correctly. The
4408 public key of the responder was not added to the computation
4409 even though it is mandatory. Affected file lib/silcske/silcske.c.
4410 This unfortunately causes incompatibilities with older
4411 clients and servers.
4413 * Added WIN32 specific network init and uninit functions:
4414 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4415 the Winsock2. Affected file lib/silcutil/silcnet.h and
4416 lib/silcutil/win32/silcwin32net.c.
4418 * Set the socket always to nonblocking mode on WIN32 after
4419 reading data or writing data. Affected file is
4420 lib/silcutil/win32/silcwin32sockconn.c.
4422 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4424 * Fixed various compilation problems under WIN32. Affected
4425 files lib/silcutil/win32/silcwin32thread.c and
4426 lib/silcutil/win32/silcwin32schedule.c.
4428 * Removed all _internal.h #includes from public header
4429 files. Internal headers must never be included from
4432 Removed also the lib/silcske/payload_internal.h file.
4434 * All include files that may be needed (public and some others
4435 included by the public headers) by application developers are
4436 now copied to the ./includes directory. It does not copy any
4437 internal headers. Affected file Makefile.defines.pre and all
4438 Makefile.am's under lib/ and subdirs.
4440 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4442 * Do not change the ~/.silc directory's permissions automatically.
4443 Affected file irssi/src/silc/core/clientutil.c.
4445 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4447 * Do not cancel the protocol in silc_server_close_connection
4448 it might cause recursion. Now cancelled in the function
4449 silc_server_free_sock_user_data. Affected file silcd/server.c.
4451 * Fixed the silc_server_remove_clients_by_server to regenerate
4452 the channel keys correctly finally. Added also new function
4453 silc_server_remove_clients_channels to actually do it.
4454 Affected file silcd/server.c.
4456 * Fixed the silc_server_new_channel to not crash by giving
4457 wrong router to the new channel. Affected file is
4458 silcd/packet_receive.c.
4460 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4462 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4463 which is given as argument to the silc_client_alloc now.
4464 It can be used to configure the client and set various parameters
4465 that affect the function of the client.
4467 * The USERS command in server did not check whether the channel
4468 is private or secret. Affected file silcd/command.c.
4470 * Added new argument to the USERS command in protocol specification.
4471 The USERS command now can take the channel name as argument
4472 as well. Added support for this in client and server and
4473 updated the protocol specs.
4475 * Completed the GETKEY command in client. It can be now used
4476 to fetch also servers public key not only some clients.
4477 Affected files lib/silcclient/command[_reply].c.
4479 * Added silc_client_get_server to return server entry by the
4480 server name. Affected files lib/silcclient/silcapi.h and
4483 * Redefined the IDENTIFY command in protocol specification to be
4484 more generic. It now can be used to query information about
4485 any entity in the SILC Network, including clients, servers and
4486 channels. The query may be based either the entity's name
4487 or the ID. Added support for this in both client and server.
4489 Affected files silcd/command.c and lib/silcclient/command.c
4490 and command_reply.c.
4492 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4493 the _from_client and _from_server functions. Affected file
4496 * Added silc_client_get_channel_by_id_resolve to the file
4497 lib/silcclient/silcapi.h to resolve channel information by
4498 its ID. Added also silc_client_get_channel_by_id that
4499 does not resolve it from the server.
4501 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4503 * Added SilcServerEntry context into the client library
4504 to represent one server. The INFO command now allocates
4505 these to save the resolved server info. For now on the
4506 client library will also keep information about servers,
4507 connected and resolved with INFO.
4509 The INFO command now allocates the SilcServerEntry context
4510 and saves the server info there. The COMMAND_REPLY in
4511 the INFO now returns the parameters to application in
4512 same order as defined in the protocol specification.
4514 The entries are cached in the client->server_cache.
4516 * The INFO command is now issued after received the Client ID
4517 from the server. Affected file lib/silcclient/client.c.
4519 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4520 to the application as the mode changer might be server.
4521 It is guaranteed that NULL is not returned anymore to the
4522 application. Affected file lib/silcclient/client_notify.c.
4524 The ID Type is now also passed to the application so that
4525 it can check whether the returned entry is SilcClientEntry
4528 Added new function silc_client_get_server_by_id to return
4529 the server entry by ID. Affected files are the
4530 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4532 * Do not create the channel in the Irssi SILC Client when issuing
4533 the JOIN command but when received the sucessful JOIN command
4534 reply. Otherwise the channel might get created even though we
4535 could not join it. The Affected file is
4536 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4538 * Fixed a channel joining bug in router. The router must also
4539 check the channel modes, invite and ban lists etc. when serving
4540 the JOIN command sent by normal server. Affected file is
4541 silcd/command.c. The router now resolves the client's
4542 information from the server who sent the JOIN command if it
4543 does not know it, and processes the JOIN command only after
4546 * Changed the SilcCommandCb to take new argument; void *context2.
4547 Affected file lib/silccore/silccommand.h
4549 The second argument in the command callbacks in the server now
4550 includes the SilcServerCommandReplyContext if the command was
4551 called as pending command callback from the command reply.
4552 Otherwise it is NULL. When called as pending the status of the
4553 command reply will be checked and if it was erronous the
4554 error will be sent to the original sender of the command.
4555 This way the client always receives the error messages even
4556 though the server was actually the one who received the error
4557 when it resent the command to router, for example. Affected
4558 files silcd/command[_reply].[ch].
4560 * Fixed sending WHOWAS command's error message to client if
4561 the requested client could not be found. It was missing.
4564 * Changed the CMODE and CUMODE commands reply arguments in the
4565 protocol specification. The Channel ID is now sent in both
4566 of the commands to identify the channel. Implemented this
4567 new feature to the client and server. Affected files
4568 lib/silcclient/command_reply.c and silcd/command.c.
4570 * Made better checks for invite and ban lists in the JOIN
4571 command in server. Affected file silcd/command.c.
4573 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4575 * The server now performs the incoming host IP/DNS lookup
4576 using the silc_socket_host_lookup and thus does not block
4577 the server anymore. Affected file silcd/server.c.
4579 * Completed the multi-thread support for SILC Scheduler in
4580 the lib/silcutil/silcschedule.c.
4582 * Fixed the configure.in.pre to detect the pthread correctly
4585 * Fixed a deadlock in silc_task_queue_wakeup in the file
4586 lib/silcutil/silctask.c.
4588 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4590 * Added new function silc_schedule_wakeup that is used in
4591 multi-threaded environment to wakeup the main thread's
4592 schduler. It needs to be used when a thread adds a new task
4593 or removes a task from task queues. After waking up, the
4594 scheduler will detect the task queue changes. If threads
4595 support is not compiled in this function has no effect.
4596 Implemented the wakeup mechanism to both Unix and WIN32
4597 systems. Affected files are lib/silcutil/silcschedule.[ch],
4598 lib/silcutil/unix/silcunixschedule.c and the
4599 lib/silcutil/win32/silcwin32schedule.c.
4601 * Added new function silc_task_queue_wakeup to wakeup the
4602 scheduler by the specified task queue. Affected file
4603 lib/silcutil/silctask.[ch].
4605 * The silc_socket_host_lookup_start now wakes up the scheduler
4606 after adding the timeout task. Affected file is
4607 lib/silcutil/silcsockconn.c.
4609 * The silc_socket_host_lookup is synchronous now if the threads
4610 support is not compiled in. However, the callback is still
4611 called asyncronously through the scheduler, anyway. Affected
4612 file lib/silcutil/silcsockconn.c.
4614 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4616 * Added new function silc_socket_host_lookup to perform
4617 asynchronous IP and FQDN lookups for the socket connection.
4618 Affected files lib/silcutil/silcsockconn.[ch].
4620 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4622 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4623 that may or may not compile the mutex support in.
4625 Changed the silc_mutex_alloc interface. It allocates the
4626 mutex now to the sent pointer and returns TRUE or FALSE.
4628 Affected file lib/silcutil/silcmutex.h.
4630 * Wrote the SILC Task Queue interface to support multi-threads.
4631 Affected file lib/silcutil/silctask.[ch].
4633 * Wrote the SILC Scheduler to support multi-threads. Affected
4634 file lib/silcutil/silcschedule.c.
4636 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4638 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4639 in lib/silcutil/win32/.
4641 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4643 * Defined SILC Mutex API and SILC Thread API and implemented
4644 them for Unix. Affected files are
4645 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4646 lib/silcutil/unix/silcunixmutex.c and
4647 lib/silcutil/unix/silcunixthread.c.
4649 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4651 * Fixed the silc_server_remove_clients_by_server's channel
4652 key re-generation. The hash table handling was incorrect
4653 and would not work with many channels. Affected file is
4656 * Fixed some memory leaks around the server code.
4658 * Rewrote the silc_server_get_users_on_channel to support IPv6
4659 based Client ID's. Affected file silcd/server.c.
4661 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4662 specification. However, a separate document must be written
4663 to define the detailed signing procedure and the payload
4664 associated with the flag. Defined the flag to the
4665 lib/silccore/silcchannel.h as well.
4667 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4669 * Changed the dynamic tables to static size tables in the
4670 lib/silccrypt/silchmac.c.
4672 * Removed GCC dependencies from the code. A patch by cras.
4674 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4676 * Do not show the error "Error receiving packet bla bla"
4677 in server if it really was not an error (-2 means that reading
4678 is pending). Affected file silcd/server.c.
4680 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4682 * Fixed a possible crash in silc_server_remove_clients_by_server
4683 in silcd/server.c. Fixed there also some memory leaks.
4685 * Fixed the silc_idlist_replace_client_id. It could replace
4686 wrong key in the hash table. Affected file silcd/idlist.c.
4688 * Do not check whether there are global users on the channel
4689 if the channel->global_users is FALSE. Affected functions
4690 silc_server_remove_from_one_channel and
4691 silc_server_remove_from_channels in silcd/server.c. Also,
4692 do not check if the removed client is local as we can be
4693 sure that global client was not removed from the channel
4694 and checking for global users is not needed.
4696 * The silc_server_remove_clients_by_server now re-generates
4697 the channel keys correctly for those channels that had
4698 clients removed from them. Affected file silcd/server.c.
4700 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4702 * Found the reason of random crashes in the server. We weren't
4703 ignoring the SIGPIPE signal (which can be sent in write())
4704 and it crashed the server. Affected file silcd/silcd.c.
4706 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4708 * Assure that sock->user_data is not NULL in the function
4709 silc_server_packet_send in silcd/packet_send.c.
4711 * Disconnect the remote connection if it could not be added
4712 to any ID lists in the server. The affected file is
4715 * Check in silc_server_packet_send[_real/dest] that the
4716 socket is not disconnecting and ignore the data if it is.
4717 Affected file silcd/packet_send.c.
4719 * Define inline to __inline on native WIN32 compilation.
4720 Affected file includes/silcwin32.h.
4722 * Added some explicit type casts for inline code since MSVC
4723 require them. Affected files lib/silcutil/silcbuffer.h,
4724 lib/trq/silcdlist.h and lib/trq/silclist.h.
4726 * Print warning in log files from now on if the packet
4727 decryption fails. Affected file silcd/server.c.
4729 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4731 * Changed the `say' client operation's interface to accept
4732 new `type' argument to indicate the type of the message sent
4733 by the library. The application may filter the library's
4734 messages according the type. The affected file is the
4735 lib/silcclient/silcapi.h.
4737 * Added two new functions to lib/silcclient/silcapi.h:
4738 silc_client_del_client and silc_client_del_client_by_id.
4739 Affected file lib/silcclient/idlist.c.
4741 * Moved the clientincludes.h from includes/ to silc/ and
4742 serverincludes.h from includes/ to silcd/.
4744 * The modes for the CMODE and CUMODE are now passed as
4745 uint32 for application with COMMAND_REPLY. The affected
4746 file is lib/silcclient/command_reply.c.
4748 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4750 * /WHOIS without arguments shows client's own information.
4751 Affected file lib/silcclient/command.c.
4753 * Changed PING to not accept any arguments. The specs
4754 says that client can ping only the connected server so
4755 requiring an argument is not needed. Affected file is
4756 lib/silcclient/command.c.
4758 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4760 * Fixed a fatal bug in private message sending and reception
4761 encryption and decryption when using private message keys.
4762 The implementation was incorrect and did not follow the
4763 specification. It causd that some of the message were
4764 lost since it did not use the sending and receiving keys
4765 as the protocol suggests. This has been fixed and will cause
4766 incompatibilities with older clients when sending private
4767 message encrypted with private message keys. Affected files
4768 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4769 and various other in Irssi SILC Client.
4771 Added `responder' boolean argument to the functions
4772 silc_client_add_private_message_key[_ske] to indicate when
4773 the key is added as responder or initiator of the key
4776 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4778 * Removed the silc_ske_check_version function and created
4779 a SilcSKECheckVersion callback. Added also a function
4780 silc_ske_set_callbacks that is now used to set all SKE
4781 callbacks. The callback functions are not given to
4782 the SKE functions anymore, but this function is used to
4785 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4787 * Added `silc_version' argument to the silc_client_alloc
4788 to define the version of the application for the library.
4789 The library will use the version string to compare it
4790 against the remote host's (usually a server) version
4791 string. Affected file lib/silcclient/silcapi.h
4793 * Added the KE protocol context to Key Agreement context
4794 in client library so that we can abort the SKE if it
4795 is in process when we get timeout. Affected file is
4796 lib/silcclient/client_keyagr.c.
4798 * Do not resolve the client ID forever if it returns in the
4799 first time that such client does not exist. This was done
4800 for example with private message. Affected file is
4801 lib/silcclient/client_prvmsg.c.
4803 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4805 * Do not add regex.h for WIN32. The affected file
4806 includes/silcincludes.h.
4808 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4809 not work yet 100%. It generates the DLL's automatically
4810 when compiling with --with-win32 under cygwin.
4812 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4814 * lib/contrib/regex.c is not compiled on WIN32.
4816 * Added silc_net_get_socket_opt function to the
4817 lib/silcutil/silcnet.h.
4819 * Added includes/silcwin32.h for WIN32 specific includes
4822 * Do not use ptime structure or any of the posix process
4823 functions on WIN32 in lib/silccrypt/silrng.c.
4825 * Added silc_gettimeofday to provide generic function
4826 for struct timeval on all platforms. Added the function
4827 to lib/silcutil/silcutil.h.
4829 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4831 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4832 library as they clearly belong there. As a plus side we
4833 can make the actual socket connection routines platform
4836 Added also new generic function silc_socket_read and
4837 silc_socket_write (that used to be silc_packet_[read/write].
4838 The implementation of these are platform specific.
4840 * Added WIN32 specific routines of silc_socket_[read/write]
4841 to lib/silcutil/win32/silcwin32sockconn.c.
4843 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4845 * Added preliminary support for native WIN32 compilation under
4846 cygwin (using the -mno-cygwin option for GCC) to the
4847 ./configure.in.pre. The --with-win32 now prepares the
4848 compilation for native WIN32.
4850 * Rewrote the SILC Scheduler interface in the file
4851 lib/silcutil/silcschedule.h. The scheduler is now context
4852 based and does not have anymore any global static scheduler.
4853 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4854 and created lib/silcutil/win32 directory for WIN32 based
4857 * Added Unix specific network routines to the
4858 lib/silcutil/unix/silcunixnet.c and the old
4859 lib/silcutil/silcnet.c includes now only generic routines.
4861 Added WIN32 specific network routines to the
4862 lib/silcutil/win32/silcwin32net.c.
4864 * Added Unix specific utility functions from the
4865 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4867 * Added WIN32 SILC Scheduler to the file
4868 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4871 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4873 * Do not handle JOIN notify in the server if the target client
4874 is not registered (idata->registered == FALSE). The affected
4875 file is silcd/packet_receive.c.
4877 * Update the nickrec->founder in event_cumode in the Irssi SILC
4878 client. Affected file irssi/src/silc/core/silc-channels.c.
4880 * Fixed the CUMODE_CHANGE notify handling in the server when
4881 server and router are announcing their clients on channels.
4882 Now the mode changes are saved and notified correctly. The
4883 affected file is /silcd/packet_receive.c.
4885 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4886 They really did not replace the cache entry in the ID Cache.
4887 Now they do that. Affected file silcd/idlist.c.
4889 * Fixed the KICK notify handling in the Irssi SILC client to
4890 update the channel records so that the kicked client does not
4891 appear to be on the channel. The affected file is
4892 irssi/src/silc/core/silc-channels.c.
4894 * Always update the conn->current_channel when executing command
4895 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4897 * Fixed the KILL notify handling in Irssi SILC client to remove
4898 the killed client on all channels.
4900 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Fixed the silc_parse_command_line to remove extra spaces
4903 from the start and end of the arguments. Affected file is
4904 lib/silcutil/silcutil.c.
4906 * Cancel and free any active protocol in the function
4907 silc_server_close_connection. Affected file silcd/server.c.
4909 * Cancel and free any active protocol in the function
4910 silc_client_close_connction. Affected file is
4911 lib/silcclient/client.c.
4913 * Do not execute the KILL command for clients that are in
4914 history (ie. they are not in the network). Affected file is
4917 * Fixed KILL notify handling, client does not crash anymore.
4918 Affected file irssi/src/silc/core/silc-channels.c.
4920 * Reduced the default packet buffer size from 2048 to 1024 in
4921 lib/silccore/silcpacket.c.
4923 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4924 counter to the SKE context that is incresed when the SKE library
4925 performs async operation outside the library. If the outside
4926 process frees the SKE context and FREED status will be set
4927 and the library will detect after the sync operation that the
4928 libary is freed. The affected files are
4929 lib/silcske/silcske[_status].[ch].
4931 * Resolve the client entry information in the function
4932 silc_client_channel_message to assure that NULL pointer is not
4933 passed as client entry to the application. */
4935 * Fixed the task timeout calculation to assure that there is
4936 never negative timeouts. The affected file is
4937 lib/silcutil/silcschedule.c.
4939 * Fixed the channel user mode notification sending in server.
4940 It was sent point-to-point to the router (or to server by router)
4941 but it needs to be destined to a channel. The routines now
4942 supports sending the channel user mode notifys to the channels
4943 when announcing clients and channels. Affected files are
4944 silcd/server.c and silcd/packet_receive.c.
4946 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4947 It did not actually replace the old channel entry in the cache.
4948 Affected file lib/silcclient/client_notify.c.
4950 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Fixed a possible crash in silc_packet_send_prepare. It now
4953 assures always that there is enough space in the buffer and
4954 at the tail area of the buffer (for MAC).
4956 Fixed the inbound buffer reallocation in silc_packet_read.
4957 It was old code and did not handle the reallocation correctly.
4960 The affected file is lib/silccore/silcpacket.c.
4962 * Fixed buffer overflow in silc_parse_nickname in the file
4963 lib/silcutil/silcutil.c.
4965 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4967 * make install generates new server keys only if there is not
4970 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4972 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4973 Added check that if the NOREPLY is set then we will not send
4974 the away message. This avoids infinite loop of away messages
4975 if both clients are away. The affected file is
4976 lib/silcclient/client_prvmsg.c.
4978 * Fixed client crash if /NICK was given without arguments.
4979 Affected file lib/silcclient/command.c.
4981 * Server does not send the invite list in INVITE command back
4982 to the client if the list was not altered. Added this notion
4983 to the protocol spec as well. Affected file silcd/command.c.
4985 Fixed possible crash in INVITE command by checking the
4986 value of silc_server_get_client_route command.
4988 * Fixed the INVITE notify type handling. The arguments are now
4989 taken in correct order and client does not crash. The affected
4990 file is irssi/src/silc/core/silc-channels.c.
4992 Removed the "Inviting xxx to channel" message from the
4993 client library away and let the application handle it.
4994 Affected file lib/silcclient/command.c. Added that message
4995 to Irssi SILC client's message formats.
4997 * Fixed CMODE command crash in client. It now checks the
4998 amount of arguments correctly and does not crash. The affected
4999 file is lib/silcclient/command.c.
5001 * Do not create new channel automatically in silc_channels_join
5002 but check whether the channel by that name already exists.
5003 Affected file irssi/silc/core/silc-channels.c.
5005 * Do not send the SERVER_SIGNOFF to router if the disconnected
5006 entity was the router. Affected file silcd/server.c.
5008 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5009 SILC client as it was missing from there.
5011 Added the handling of the KICK notify to the Irssi SILC client
5012 as it was missing. Added "you have been kicked" message to
5013 Irssi SILC client's message modules formats.
5015 Added the handing of the KILL notify to the Irssi SILC client
5016 as it was missing. Added the kill message module formats
5019 The affected file is irssi/src/silc/core/silc-channels.c.
5021 * The router did not save the channel mode the server announced.
5022 Affected file silcd/packet_receive.c.
5024 * Fixed a possible crash in INFO command in server. If the
5025 server did not provide the server info it crashed. Affected
5026 file silcd/command.c.
5028 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Fixed the GETKEY command in the server to check also the
5031 global list. Otherwise the GETKEY would not work correctly
5032 in normal SILC server. Affected file silcd/command.c.
5034 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5036 * Fixed GETKEY crash, it crashed if the command did not succseed.
5038 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5040 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5041 is now real and not just an macro interface to GMP.
5043 Removed the entire GMP from the source tree and imported new
5044 NSS MPI library instead. Reason for removing GMP is that it is
5045 extremely large and compiles extremely slow. The NSS MPI
5046 is only a few files and compiles in less than 10 seconds.
5047 The speed is also about the same as GMP. The MPI is imported
5048 to lib/silcmath/mpi.
5050 If the system has GMP installed we will still use the GMP.
5051 If it is not then the NSS MPI will be compiled.
5053 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5055 * Merged a long nickname (127 characters long) crash bugfix from
5056 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5058 * Merged a freed memory reference bugfix from Irssi CVS tree.
5059 Affected file irssi/src/core/commands.c.
5061 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5063 * Added the server's public key sving and verification to the
5064 server when performing the SKE. This was missing and the
5065 remote server's (or router's) public key was accepted without
5066 checking whether we have it previously or trust it at all.
5067 Affected file silcd/protocol.c.
5069 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5071 * Check in the silc_server_timeout_remote if protocol is active
5072 and make sure that the protocol's final callback is called so
5073 that all memory if freed. Affected file silcd/server.c.
5075 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5077 * silc_server_whois_send_reply crashed the server if the nickname
5078 was 127 characters long. Affected file silcd/command.c.
5080 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5082 * Added sanity check to the silc_server_new_client. If the hostname
5083 is provided inside username then check that the provided hostname
5084 really is the same as the resolved one. If the hostname was not
5085 resolved then check it from the public key. Affected file is
5086 silcd/packet_receive.c.
5088 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5089 if the server disconnected us and the connection is not valid
5090 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5092 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5093 the library to the lib/silcutil/silcutil.[ch].
5095 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5097 * Close log file after open. Affected file
5098 lib/silcutil/silclog.c.
5100 * Check whether sock == NULL in silc_client_send_packet and return
5101 if it is. Affected file lib/silcclient/silcclient.c.
5103 * Check rec->entry == NULL in the Irssi SILC Client before
5104 sending the channel message. Affecte file is
5105 irssi/src/silc/core/silc-servers.c.
5107 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5109 * Merged a splitted window bugfix from Irssi CVS tree. The
5110 affected file is irssi/src/fe-text/textbuffer-view.c.
5112 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5113 It did not print nickname.
5115 * Improved the distributions system a bit.
5117 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5119 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5120 irssi/src/fe-text/gui-window.c.
5122 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5123 to in-active server. The affected file is
5124 irssi/src/silc/core/client_ops.c.
5126 * Resolve the client in USERS command reply if the entry does
5127 not have username resolved. The affected file is
5128 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5129 command to WHOIS command to really resolve stuff. The USERS
5130 is not used any more in any critical section so WHOIS can
5131 be used even though it might be slower than IDENTIFY.
5133 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5136 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5138 * Changed the protocol API a bit more consistent in the
5139 lib/silccore/silcprotocol.[ch].
5141 * Changed the following headers to ROBODoc format:
5143 lib/silccore/silcpayload.h
5144 lib/silccore/silcprotocol.h
5145 lib/silccore/silcsockconn.h
5147 All core library headers are now formatted.
5149 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5151 * Fixed a bug in Irssi SILC client; do not show that you are
5152 server/router operator if you really are not. Affected file is
5153 irssi/src/silc/core/client_ops.c.
5155 * Renamed silc_command_free_payload to silc_command_payload_free.
5156 Affected file lib/silccore/silccommand.h
5158 * Added silcmath.h to include the prototoypes of various routines
5159 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5162 * Changed the following headers to ROBODoc format:
5164 lib/silccore/silcchannel.h
5165 lib/silccore/silccommand.h
5166 lib/silccore/silcid.h
5167 lib/silccore/silcidcache.h
5168 lib/silccore/silcmode.h
5169 lib/silccore/silcnotify.h
5170 lib/silccore/silcpacket.h
5171 lib/silcmath/silcmath.h
5173 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5175 * Added checking to the server code not to start the server if
5176 ciphers and stuff are not configured properly. Affected files
5177 silcd/serverconfig.[h] and silcd/server.c.
5179 * Changed the layout of the header files of the public interfaces
5180 in the SILC libraries. The new layout supports ROBODoc
5181 documentation tool (and some others) so that it is easy to create
5182 a library reference manual. All the other headers and source
5183 code must still follow the CodingStyle document. Also source
5184 code must not include these ROBODoc stuffs, only the headers.
5185 Furthermore, all public interface headers must now be named
5186 by using `silc' prefix, example: silcapi.h, silccipher.h.
5187 Some files were renamed due to this. All the other headers
5188 must not be used as public interfaces. I will update the
5189 CodingStyle document later. Changed following headers, so far:
5191 lib/silcclient/silcapi.h
5192 lib/silccore/silcauth.h
5193 lib/silccore/silcprivate.h
5194 lib/silccrypt/silcdh.h
5196 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5200 * Removed silc_client_packet_send_flush from the client library
5201 as it is not needed. Affected file lib/silcclient/client.[ch].
5203 * Added printing of message of unresolved authentication method
5204 to the Irssi SILC client. Added it to the module formats.
5205 Removed the same message from the client library.
5207 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5209 * Added new distribution feature, DISTLABEL. Every distribution
5210 can define own preprocessor label that can be used in the
5211 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5212 file distributions, acconfig.h.pre and prepare.
5214 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5216 * Added Makefile.defines_int to include the actual definitions
5217 for Makefile.defines.in. Tested the new distribution system,
5218 created distributions and tested installation.
5220 * Added AWAY message printing to the Irssi SILC client. Added
5221 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5223 * Added SCONNECT command to call the SILC's CONNECT command.
5224 Cannot use CONNECT directly since Irssi uses that internally.
5225 Affected file irssi/src/silc/core/silc-servers.c.
5227 Added ACTION local command. It is same as ME command but takes
5228 the channel as mandatory argument.
5230 Rewrote some of the Irssi's help files to suite for SILC
5233 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5235 * Added Makefile.defines[.in] that should for now on be included
5236 in all Makefile.am file in the source tree. That file includes
5237 all common compilation definitions for SILC source tree.
5239 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5241 * Minor changes to the ./prepare script to change the package
5242 name according the distribution name to the configure.in.
5244 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5246 * Created new distribution system. Added file `distributions'
5247 that defines all the distributions that can be created out of
5248 the SILC source tree. The ./prepare script now reads that
5249 file to determine how to prepare the distributions. The
5250 first argument to the ./prepare is the name of the distribution
5251 and second is the version of the distribution. If given
5252 without arguments it creates the default (toolkit) distribution
5253 with the default version (defined in ./prepare).
5255 All Makefile.am files that are subject to the distributions
5256 are now named as Makefile.am.pre. These are ./Makefile.am
5257 and lib/Makefile.am. Others may be changed later.
5259 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5261 * Added invite list, ban list, some key management and connection
5262 error message printing to module formats in the Irssi SILC client.
5264 * Added new silc_client_set_away_message to set the away message
5265 that is back to the person who sent private message. The
5266 affected file lib/silcclient/silcapi.h and the
5267 lib/silcclient/client_prvmsg.c.
5269 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5271 * Fixed the private message sending in the Irssi SILC client,
5272 added local command KEY to the Irssi SILC client.
5274 Added key management and key agreement message formats to the
5275 irssi/src/fe-common/silc/module-formats.[ch].
5277 Added USERS (alias WHO) printing, server/router operator
5278 indication and LIST command printing to the module formats.
5280 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5282 * Fixed channel joining notify handling, cumode notify handling
5283 from Irssi SILC client.
5285 * Added SILC specific module-formats to the Irssi SILC client so
5286 that SILC specific message hilighting, colors etc is possible.
5287 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5289 Added channel mode, channel user mode, actions, notices,
5290 whois and whowas printing to the the module-formats.c.
5292 * Fixed a bug in channel deletion in the server. The channel
5293 is not left to the cache even if the channel founder auth mode
5294 is set when there are no users anymore on the channel. Affected
5295 file silcd/server.c.
5297 * The silc_net_localhost now resolves the entire hostname including
5298 the domain name. Affected file lib/silcutil/silcnet.c.
5300 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5302 * Changed the ask_passphrase client operation to be ascynchronous.
5303 It has now a completion callback and a context that the
5304 application must call after it has got the passphrase from
5305 the user. Affected files lib/silcclient/silcapi.h,
5306 lib/silcclient/protocol.c, lib/silcclient/command.c and
5309 Added SilcAskPassphrase callback that the application calls
5310 to deliver the passphrase to the library.
5312 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5313 The public key verification and especially a certificate
5314 verification is asynchronous procedure.
5316 Added new SILC_SKE_STATUS_PENDING status to indicate the
5317 request is pending and a callback will be called to finalize
5320 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5321 indicate that remote end did not send its public key (or
5322 certificate), even though we require it. Added check for this
5323 condition in the SKE. This was a security bug, now fixed.
5325 Defined new SilcSKEVerifyCbCompletion callback that is called
5326 when the verification process is completed.
5328 The affected files lib/silcske/silcske_status.h and
5329 lib/silcske/silcske.[ch].
5331 * Changed the verify_public_key client operation to be async
5332 as well. Defined SilcVerifyPublicKey callback that is used to
5333 indicate the success of the public key verification process.
5335 Changed the server and client to use the new async client
5338 * Changed the Irssi SILC client's internal scheduler to be called
5339 twice as many times as it used to be. As a result the client
5340 should be a bit faster now. Affected file is
5341 irssi/src/silc/core/silc-core.c.
5343 * Added support to Irssi SILC client of asynchronous public key
5344 verification and passphrase inquiry. Affected file is
5345 irssi/src/silc/core/silc-core.c.
5347 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5349 * Do not say "You have left channel %s" in client library.
5350 Moved it to the application. Affected files are
5351 lib/silcclient/command.c and silc/client_ops.c.
5353 * Fixed silc_client_get_clients. Command context was not
5354 duplicated and was freed memory in the callback. Affected
5355 file lib/silcclient/idlist.c.
5357 * Do not say "you are now talking..." on JOIN command in the
5358 client library. The appliation must handle it.
5360 * Do not say ".. changed topic to" in command reply in the
5361 client libary. The application must handle it.
5363 * Fixed TOPIC command sending in the client library.
5365 * Fixed a memory leak in silc_client_command_free in the file
5366 lib/silcclient/command.c.
5368 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5370 * Imported a modified version of Irssi client to the source tree.
5371 The Irssi will be used to create a new client called
5372 Irssi SILC. Imported to irssi/.
5374 Added silc_core_init_finish function to the Irssi. Affected
5375 file irssi/configure.in.
5377 A lot changes in the Makefile.ams around the irssi tree.
5379 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5381 * Do not rehash if the new size is same as the old size of the
5382 hash table, in the silc_hash_table_rehash*. The affected file
5383 lib/silcutil/silchashtable.c.
5385 * Replaced hash_table_del_by_context calls from the server
5386 (when channel->user_list and client->channels) to the
5387 hash_table_del as it is sufficient and faster.
5389 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5391 * Added silc_hash_table_list, silc_hash_table_get and the
5392 SilcHashTableList structure to provide an alternative way to
5393 traverse the hash table. The affected files are
5394 lib/silcutil/silchashtable.[ch].
5396 * Changed the server's idlist routines to use the hash table
5397 routines to optimize the code.
5399 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5401 * Replaced the client entry's `channel' list and channel entry's
5402 `user_list' list to hash tables for optimized lookup. Changed
5403 the code to use the hash table interface around the code.
5404 Affected file lib/silcd/idlist.[ch].
5406 * Added `auto_rehash' boolean argument to the function
5407 silc_hash_table_alloc to indicate whether the hash table should
5408 auto-rehash when it thinks is appropriate time. It will
5409 increase the hash table size if the there is twice as much
5410 entries in the table than the size of the table, and will
5411 decrease the size if there are twice as less entries than
5412 the size of the table.
5414 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5416 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5418 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5420 * silc_idcache_purge_by_context deletes the entry now by context
5421 as it is supposed to do. Affected file lib/silccore/idcache.c.
5423 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5424 client is not anymore valid (WHOWAS givens the info) and not
5425 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5427 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5429 * Removed the `data' and `data_len' arguments from the ID Cache
5430 interfaces and added `name' argument. ID Cache does not handle
5431 anymore the binary data only a names associated with given ID.
5433 * When hashing a Client ID with silc_hash_id the entire ID is
5434 not hashed anymore, instead only the hash of the Client ID is
5435 hashed. This way we can access the Client ID from the cache
5436 with Client ID but with the hash of the ID (which is a hash of
5437 the nickname) as well without any difference in performance.
5439 Added also silc_idcache_find_by_id_one_ext to do one on one
5440 searching when we have the actual ID. Added also function
5441 silc_hash_client_id_compare. The affected files are
5442 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5444 * When hashing the name associated with a ID it is always done
5445 in lowercase. This way we can access the cache without worrying
5446 about case-sensitivity, even though, for example nicknames are
5449 * Fixed a bug in server with channel message sending. It put
5450 wrong ID type as destination ID. The affected file
5451 silcd/packet_send.c.
5453 * silc_idcache_del_by_context now deletes from all hash tables
5454 by context. Affected file lib/silccore/idcache.c.
5456 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5458 * Changed the client library to use the new ID Cache interface.
5459 Changes around the source tree.
5461 * Added silc_hash_table_rehash_ext to rehash with specific
5462 hash function. Affected file lib/silcutil/silchashtable.[ch].
5464 * Added silc_hash_string_compare to compare two strings in the
5465 hash table. Affected file lib/silcutil/silcutil.[ch].
5467 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5469 * Added new function silc_idcache_del_by_context into the
5470 lib/silccore/idcache.[ch].
5472 * Changed the server's ID list routines to use the new ID Cache
5473 interface. Changes around the source tree.
5475 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5477 * Added silc_hash_table_del[_by_context]_ext functions in to the
5478 lib/silcutil/silchashtable.[ch].
5480 Removed silc_hash_table_find_all* routines and added new
5481 silc_hash_table_find_foreach to replace them.
5483 Added silc_hash_table_replace_ext function as extended
5484 replacing function. Separated the simple hash table interface
5485 from the extended hash table interface in the file
5486 lib/silcutil/silchashtable.h.
5488 * Fixed minor bugs and changed it to use some of the new
5489 hash table functions in lib/silccore/idcache.c
5491 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5493 * Added new function silc_hash_table_find_all to return all keys
5494 in the hash table by the specified key. As the hash table is
5495 collision resistant it also makes it possible to have several
5496 duplicate keys in the hash table. This function may be used to
5497 find all of the keys from the hash.
5499 Added user_context arguments to the SilcHashFunction,
5500 SilcHashCompare and SilcHashDestructor to deliver user specified
5503 Added new fuctions silc_hash_table_find[_all]_ext to do
5504 extended lookup with specified hash and compare functions and
5505 specified user contexts.
5507 Added new function silc_hash_table_add_ext to add the key
5508 with specified hash function and user context.
5510 Added new function silc_hash_table_foreach to traverse all
5511 entrys in the hash table. Added SilcHashForeach callback
5514 Added new function silc_hash_table_del_by_context to delete
5515 the entry only if the context associated with the key matches.
5517 Affected files are lib/silcutil/silchashtable.[ch].
5519 * Removed silc_hash_[server/client/channel]_id and added just
5520 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5521 silc_hash_id_compare to compare two ID's using as the hash table
5522 comparison function. Added also silc_hash_data to hash
5523 binary data and silc_hash_data_compare to compare it.
5525 * Removed silc_idlist_find_client_by_hash as it is not needed
5526 anymore. Affected file silcd/idlist.[ch].
5528 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5529 to use internally the SilcHashTable. The new ID Cache is a lot
5530 faster than the old one. Some of the ID Cache interface was also
5531 rewritten and obsolete and stupid functions were removed.
5533 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * Added entry_count field to the SilcHashTable to keep the number
5536 of the entries in the table. Implemented the function
5537 silc_hash_table_rehash. Added new function
5538 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5540 Fixed a minor bug in silc_hash_table_free.
5542 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5543 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5544 into the lib/silcutil/silcutil.[ch].
5546 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5548 * Implemented a collision resistant hash table into the
5549 lib/silcutil/silchashtable[ch]. See the header and the source
5550 for the SilcHashTable API.
5552 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5554 * Merged dotconf version 1.0.2 into lib/dotconf.
5556 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5558 * Do not compile anything in lib/silcsim/* if the SIM support
5559 is not enabled. The tree should now compile without problems
5562 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5564 * Compiled the SILC under cygwin. Compiled and tested briefly
5565 without problems. More tests needed. The SIMs didn't compile
5568 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5570 * Fixed possible crash in silc_get_username in the
5571 lib/silcutil/silcutil.c.
5573 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5575 * Fixed a va_arg in silc/client_ops.c.
5577 * Oops, RC5 routines were named AES and caused some problems
5578 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5580 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5582 * Added new SilcIDIP structure into the lib/silccore/id.h and
5583 replaced the old `ip' fields from all SILC ID's to that type.
5584 This is a step towards IPv6 support.
5586 The silc_id_get_len takes now the ID as an extra argument.
5587 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5588 both IPv4 and IPv6 based ID's.
5590 The affected files are lib/silccore/id.[ch] and other files
5591 around the tree using these routines.
5593 * Removed the ID length arguments in server from various
5594 silc_server_send_notify_* routines -> they are not needed
5597 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5599 * Fixed memory leak in silc_encode_pem_file in the file
5600 lib/silcutil/silcutil.c.
5602 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5604 * Check minor version as well in the SKE. Affected files are
5605 silcd/protocol.c and lib/silcclient/protocol.c.
5607 * Added --identifier option to the server so that an identifier
5608 can be when creating the public key for the server. Affected
5609 file is silcd/silcd.c.
5611 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5612 lib/silccrypt/silcpkcs.c.
5614 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5616 * Register default ciphers and stuff when using -C option with
5617 the server. Affected file sildc/silcd.c.
5619 * Put back the servers public key filename format, it is better
5620 than the new one. For now, the client keys are saved with the
5621 new filename format. The affected file silc/client_ops.c.
5623 * Implemented the Cipher API for the rest of the ciphers that
5624 did not implement it or implemented it the wrong way.
5626 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5628 * Register default ciphers and stuff when using the -S option
5629 in the client. Affected file silc/silc.c. Same also when
5630 creating new key pair with -C option.
5632 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5634 * Fixed the silc_verify_public_key client operation function to
5635 save the public keys differently. The fingerprint is now
5636 used as filename and not the hostname. This way also the
5637 client keys are saved uniquely and not with hostnames. The
5638 affected file is silc/client_ops.c.
5640 * Trimmed the silc_hash_fingerprint function to remove extra
5641 whitespaces from the end of the fingerprint. The affected
5642 file is lib/silccrypt/silchash.c.
5646 * Added silc_cipher_register_default function to register all
5647 default ciphers. It can be used when configuration files
5648 does not exist and the application does not want any specific
5649 ciphers in any specific order.
5651 The SilcDList is now used as silc_cipher_list dynamically
5652 allocated cipher list. Removed the static list all together
5653 and now all ciphers must be allocated to the dynamic list.
5654 The silc_cipher_alloc routine was changed to check only the
5657 All silc_cipher_* routines that used to return int returns
5660 The affected files lib/silccrypt/silccrypt.[ch].
5662 * The same thing was done to silc_hash_* as for silc_cipher_*
5663 routines. Affected files lib/silccrypt/silchash.[ch].
5665 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5666 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5667 Added also silc_pkcs_[un]register[_default] functions.
5668 Removed the data_context from the PKCS API.
5670 * Added silc_hmac_register_default function to register default
5671 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5672 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5673 to unregister all hmacs at once.
5675 * Register the default ciphers, hash functions, PKCSs and HMACs
5676 if client's configuration file does not exist. The affected
5679 * The client did not load the hash functions from the SIM
5680 modules at all. Added support for this. Affected file is
5681 silc/clientconfig.c.
5683 * When decoding public key with silc_pkcs_public_key_decode, check
5684 the supported algorithm only if PKCS are registered. Affected
5685 file lib/silccrypt/silcpkcs.c. The same was done with the
5686 silc_pkcs_private_key_decode.
5688 * Fixed the SILC List routines to keep the list always in order.
5689 It used to change the list's order when traversing the list but
5690 not it preserves the order. Affected file lib/trq/silclist.h.
5692 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5694 * Added the client library to use the SilcSocketConnection's
5695 reference counter (by silc_socket_dup) to prevent the bug that
5696 the socket object may be freed underneath async operation.
5698 * The name resolv library checking fixes in the configure.in.pre.
5701 * Created new version of the protocol drafts for future
5702 development. The -03 drafts are the ones that will be changed
5703 in the trunk now and the -02 will remain as they are.
5705 * Send list of CUMODE notifys to the router when announcing
5706 the channel users to the router. Affected file silcd/server.c.
5707 If the router receiving channel founder CUMODE for a channel
5708 that already has channel founder it will send CUMODE notify
5709 to the sender to remove the channel founder rights from the
5710 announced client. Affected file silcd/packet_receive.c.
5712 * The CUMODE notify may now use Server ID as well as the entity
5713 who changes the mode. Updated protocool specs.
5715 * Updated INSTALL and README files.
5717 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5719 * New web pages in the http://silc.pspt.fi. The pages was
5724 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5726 * Implemented the [DenyConnectin] config section in the server.
5727 Added silc_server_config_denied_conn to check whether incoming
5728 connection is denied. Affected file silcd/serverconfig.[ch].
5730 * Do not check the ports when checking the incoming configuration
5731 data if the port is 0, meaning any. Affected file is
5732 silcd/serverconfig.c.
5734 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5736 * Fixed buffer overflow in silc_string_compare in the file
5737 lib/silcutil/silcutil.c.
5739 * Fixed double free in silc_server_command_leave in the file
5742 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5744 * Fixed the version checking in the server. Affected file is
5747 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5749 * Fixed the configuration data fetching when accepting new
5750 connections in the server. Affected file silcd/server.c.
5752 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5754 * Added `sender_entry' argument to the function
5755 silc_server_packet_relay_to_channel so that we can check
5756 whether some destination actually belongs to the same route
5757 the sender belongs (ie, we must not resend the packet to the
5758 sender). Affected file silcd/packet_send.[ch].
5760 * Added `servername' field to the SilcClientEntry in the server
5761 to hold the name of the server where client is from. Affected
5762 file is silcd/idlist.h.
5764 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5766 * Moved the channel message encrypting in the router betwen
5767 router connections from silc_server_channel_message to the
5768 silc_server_packet_relay_to_channel since we want to check
5769 whether we have anybody channel before encrypting anything.
5770 Affected files silcd/packet_[receive/send].c.
5772 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5774 * Fixed the [AdminConnection] server config section to support
5775 multiple entries. Affected file silcd/serverconfig.c.
5777 * Added support into the server to check the validity of the
5778 incoming connection before executing any KE or authentication
5781 * The connection configuration is now saved to the KE and
5782 connection auth protocol contexts and not fetched anymore in
5783 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5785 * The local hosts listenning address and port is also resolved
5786 now when starting the server. We want to have the socket object
5787 to include the real address and port for the listener. Added
5788 new function silc_net_check_local_by_sock into the files
5789 lib/silcutil/silcnet.[ch].
5791 * Fixed a broadcast bug in server -> do not broadcast if we
5794 * Fixed a routing bug. Do not route broadcast packets ever.
5795 Broadcast packets must be processed always and not routed since
5796 they may be destined to some other host than yourself and thus
5797 would get routed without no good reason. Affected file is
5800 * Added function silc_server_config_is_primary_route to check
5801 whether primary router connection has been configured (a router
5802 configuration that we are initiating). If there is not, we
5803 will assume that there is only two routers in the SILC network
5804 and we will use the incoming router connection as our primary
5805 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5807 * Changed the order of the broadcasting. Broadcast _after_ the
5808 packet has been processed not before. Affected file is
5811 * Fixed a [ClientConnection] parsing bug. The port was never
5812 parsed correctly thus resulting to port 0. Affected file
5813 silcd/serverconfig.c.
5815 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5816 argument and did not set the broadcast packet flag. Affected
5817 file silcd/packet_send.c. Fixed same bug in the function
5818 silc_server_send_notify as well.
5820 * If we receive NEW_ID packet for our own ID in the server, ignore
5823 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5827 * Removed the nickname from the Private Message Payload.
5828 Updated the code and the protocol specs.
5830 * Updated protocol specs for submitting to the IETF.
5832 * Tweaked the Random Number Generator a bit. Affected file
5833 lib/silccrypt/silcrng.c. Exported a new function
5834 silc_rng_[global]_add_noise which can be used to add more
5837 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5839 * Do not parse packets with different timeout when protocol
5840 is active -> may cause problem with rekey. Affected file
5843 * When server receives signoff notify it must not create
5844 new channel key if the client is on any channels since the
5845 sender of the signoff notify will create it.
5847 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5849 * Added printing of error messages during SKE protocol from the
5850 failure packet sent by server during SKE. Affected file
5853 * Removed the client's failure_callback handling with timeout
5854 and handle it immediately when received.
5856 * The SKE library returned wrong type in SUCCESS and FAILURE
5857 packets. They must be 32 bit MSB not 16 bit MSB.
5859 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5861 * Ok, rewrote the logic of the re-key and now it seems to work.
5862 I tested it on high traffic with frequent re-keys without
5863 problems. Added hmac_receive (and renamed hmac to hmac_send)
5864 in SilcClientConnection in lib/silcclient/client.h and
5865 in SilcIDListData in silcd/idlist.h. Also, removed the
5866 SilcPacketParserContext's cipher and hmac fields as they are
5867 not needed anymore and actually caused some problems when
5868 the ciphers and hmac's changed underneath the packet parser.
5870 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5872 * If re-key protocol is active then process the incoming packets
5873 synchronously since we must assure that icoming packets encrypted
5874 with the old key is processed before the new keys is set to
5875 use. This is true other packets than for REKEY packets.
5876 Affected file silcd/server.c. The same was done to client library
5877 as well, affected file lib/silcclient/client.c.
5879 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5881 * Fixed bug in client and server to accept the force send if
5882 the packet is send from silc_[server/client]_packet_process
5883 function. Otherwise the packets are never delivered, oops.
5885 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5887 * Disable force sending of packets when REKEY protocol is active.
5888 We must assure that no packet is sent directly when rekey is
5889 performed. All packets must be sent through packet queue.
5890 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5891 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5892 function is silc_[server/client]_packet_send_real to check
5895 * Replaced the SIM paths from example config files to
5896 /usr/local/modules. Also, make install creates now
5897 /usr/local/silc/logs directory to hold all the SILC server
5900 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5902 * Made the configure.in.pre work on Solaris. Patch by salo.
5904 * Made all ciphers compatible with non-x86 machines. Defined
5905 CBC mode macros into lib/silccrypt/ciphers_def.h.
5907 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5909 * Fixed the make install.
5911 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5913 * When MAC computation fails the silc_packet_decrypt returned 0
5914 even though it was supposed to return -1. Fixed this. The
5915 affected file is lib/silccore/silcpacket.c.
5917 * Do not replace the config files in /etc/silc (in make install)
5918 if they already exist. Affected file ./Makefile.am.
5920 * Do not send re-key packets immediately but through packet queue.
5921 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5923 * Changed silc_net_check_host_by_sock to return FALSE if the
5924 IP/DNS could not be resolved. Though, it returns the IP address
5925 now even if it could not resolve it (but returns also FALSE).
5926 Affected file lib/silcutil/silcnet.[ch].
5928 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5930 * Added silc_pkcs_decode_identifier to decode the public key's
5931 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5932 Added also silc_pkcs_free_identifier. Added also new context
5933 SilcPublicKeyIdentifier.
5935 * Added -S option to the silc client. It is used to dump the
5936 contents of the specified public key file.
5938 * Changed the PKCS api to return the public key length when
5939 setting the public key.
5941 * Fixed a fatal bug in the public and private key file loading.
5942 Affected file lib/silccrypt/silcpkcs.c.
5944 * Execute the packet parsing for client with zero (0) timeout
5945 if the protocol is active. Affected file silcd/server.c.
5947 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5949 * Made the key generation options to the silcd program. Added
5950 -C option, equivalent to client's option.
5952 * Added new [ServerKeys] config section to the server. It
5953 configures the server's public and private key.
5955 * Defined generic Public Key Payload into the protocol
5956 specification to send specific type of public keys and
5959 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5960 public key or certificate.
5962 * Implemented the GETKEY command to the server and to the
5963 client library and on user interface.
5965 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5967 * Made preliminary `make install' work.
5969 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5971 * Added SilcServerRekey context into silcd/idlist.h.
5973 * Added the PFS support as defined in the specification to the
5974 SKE protocol. Affected files lib/silcske/*.c.
5976 * Added `ske_group' field to the SilcServerRekey context to hold
5977 the number of the SKE group that is used with PFS in re-key.
5978 Affected file silcd/idlist.h.
5980 * Added PFS re-key support to the server. Affected file is
5983 * Added silc_protocol_cancel to cancel execution of the next
5984 state of the protocol. Affected file is
5985 lib/silccore/silcprotocol.[ch].
5987 * Added the re-key support with and without PFS to the client
5988 library. Re-key is performed once in an hour, by default.
5990 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5991 Added silc_client_rekey_callback and silc_client_rekey_final.
5992 Affected files are lib/silcclient/protocol.[ch] and
5993 lib/silcclient/client.[ch].
5995 * Removed the `hmac_key' and `hmac_key_len' fields from the
5996 SilcClientConnection structure; not needed. Affected file is
5997 lib/silcclient/client.h.
6001 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6003 * Do not ask whether user wants to use the negotiated private key
6004 for private messages, just use it. Affected file is
6005 silc/local_command.c.
6007 * Added `send_enc_key' and `enc_key_len' fields to the
6008 SilcIDListData structure since they are needed in the re-key
6009 phase. Affected file is silcd/idlist.[ch].
6011 * Implemented the simple re-key protocol into the server.
6012 Affected files silcd/server.c and silcd/protocol.[ch]. The
6013 re-key will be performed once in an hour, by default.
6015 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6016 Added silc_server_rekey, silc_server_rekey_callback and
6017 silc_server_rekey_final.
6019 * Removed Tunneled flag from the protocol. Updated the code
6020 and the specifications.
6022 * Adde `pfs' field to the SilcIDListData to indicate whether
6023 the PFS is to be performed in the re-key. Affected file is
6026 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6028 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6029 int64 of at least the xintXX size. If void * is less that 4
6030 bytes uint32 * will be used. Defined bool as boolean.
6032 * Changed _ALL_ unsigned long and unsigned int to uint32,
6033 unsgined short to uint16 in the source tree.
6035 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6036 not handle clients that has entry->data.registered == FALSE.
6037 They are not in the network anymore. Affected file is
6040 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6042 * Implemented the sending of the SERVER_SIGNOFF notify in the
6043 server. Affected file is silcd/server.c.
6045 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6046 Added also silc_notify_payload_encode_args into the
6047 lib/silccore/silcnotify.[ch].
6049 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6050 Affected file silcd/packet_receive.c.
6052 * Implemented the SERVER_SIGNOFF notify handling in the client
6053 library. Affected file lib/silcclient/client_notify.c. Also,
6054 implemnted the printing of the SERVER_SIGNOFF info to the
6055 application. Affected file silc/client_ops.c.
6057 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6058 if the deleting was successful. Affected file silcd/idlist.[ch].
6060 * Added support for public key authentication in the connection
6061 authentication protocol in the client library. Affected file
6062 lib/silcclient/protocol.c.
6064 * Changed the server's silc_idlist_get_clients_by_* interface
6065 to support already allocated array so that new entries may be
6066 added to pre-allocated array. Affected file silcd/idlist.[ch].
6067 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6068 and command replies.
6070 * All command reply functions in the server now calls the
6071 pending command callback even if error occured. This way the
6072 error will be delivered to the client as well. Affected files
6073 silcd/command.c and silcd/command_reply.c.
6075 * Fixed INFO command to return local server's info if no server
6076 was provided. Affected file lib/silcclient/command.c.
6078 * Removed RESTART command for good. Updated the code and the
6081 * Rewrote parts of the task system. It is a bit simpler now.
6082 Removed unsued task priorities. The affected files are
6083 lib/silcutil/silctask.[ch].
6085 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6087 * Moved the USERS printing from the library to the application.
6088 Affected files lib/silcclient/command.c and silc/client_ops.c.
6090 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6094 * Added channel key re-key support. The re-key is perfomed
6095 only by the router and is done once in an hour. Added `rekey'
6096 field to the SilcChannelEntry in the server. Affected files
6097 silcd/server.c and silcd/idlist.h.
6099 * Added silc_task_unregister_by_context into the file
6100 lib/silcutil/silctask.[ch].
6102 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6104 * Added SILC_UMODE_GONE mode to indicate when the client is not
6105 present in the SILC network. Added also support to the local
6106 command AWAY that will set this mode. Added support of showing
6107 "xxx is gone" in WHOIS command. The USERS command shows the
6108 gone status as well.
6110 * Fixed setting server and router operator privileges in the
6111 server's UMODE command. Affected file silcd/command.c.
6113 * Merged the SKE KE1 and KE2 payloads into one payload. The
6114 new KE payload is equivalent to the old KE2 payload.
6116 Cleaned up the SKE Start Payload parsing. It now uses the
6117 simple buffer unformatting to do the parsing. A lot faster
6120 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6121 to the SKE that is used to indicate whether both of the SKE
6122 parties should perform authentication. By default only the
6123 responder performs authentication. By setting this flag also
6124 the initiator must do authentication. By default it is unset
6125 since in normal SKE case, client to server connection, only
6126 the responder should do authentication. When doing SKE between
6127 two clients both should perform authentication. Updated the
6128 code and the protocol specs.
6130 * A little fix to IDENTIFY command in the server. Search the
6131 client first by hash not nickname. Affected file is
6134 * Fixed the silc_client_close_connection to support closing
6135 the client to client connections wihtout deleting too much
6136 data. Affected file lib/silcclient/client.c.
6138 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6139 are received if protocol used to be active but is not anymore
6140 the application would crash due to NULL pointer dereference.
6141 Affected files silcd/server.c and lib/silcclient/client.c.
6143 * Added `hash' field to the SilcClientConnection to include
6144 the hash function negotiated in the SKE protocol.
6146 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6147 to set the channel founder authentication data. A client can
6148 claim the founder rights later by providing the authentication
6149 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6150 This way the channel founder can regain the channel founder
6151 privileges even it is left the channel. This works only on
6152 local server and the client must be connected to the same
6153 server to be able to regain the founder rights. Updated the
6154 protocol specs accordingly.
6156 Added support to the CMODE command in the client to set the
6157 founder auth data. Read the README to see how to set it.
6159 Added support to the CUMODE command to claim the founder
6160 rights. Read the README to see how to do it.
6162 Added support for the founder authentication to the Channel
6163 Entry in the server. Affected file silcd/idlist.h.
6165 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6166 server's CMODE command. Affected file silcd/command.c.
6168 * Added the following new functions into lib/silccore/silcauth.[ch]:
6169 silc_auth_get_method and silc_auth_get_data.
6171 * The server now saves the remote hosts public key to the
6172 SilcIDListData pointer. Affected file silcd/protocol.c.
6174 * The normal server now does not remove the channel entry from
6175 the cache if the founder authentication data is set. It used
6176 to remove it if the founder was the last one on the channel on
6177 the server and left the channel. The auth data is saved and
6178 if the channel is re-joined later the old entry is used with
6179 the old auth data. Affected files silcd/command_reply.c and
6182 * Removed the `pkcs' field from the SilcIDListData structure
6183 in the server; it is not used. Affected file silcd/idlist.h.
6185 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6187 * Fixed packet processing on slow links. Partial packets were
6188 never re-processed because the incoming data buffer was cleared
6189 by the application. Application must not directly clear the
6190 sock->inbuf, the packet processing routines handle it. Fixed
6191 this in client library and in server.
6193 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6195 * Fixed the WHOIS and IDENTIFY send reply function to really
6196 check whether to send list or just one entry. Affected file
6199 * Cleaned up the LEAVE command's channel key distribution. The
6200 affected file silcd/command.c.
6202 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6203 can enforce the channel mode as well. In that case the ID
6204 includes the ID of the server. The code now enforces the
6205 mode change if the router have different mode than the server.
6207 * The notify client operation with CMODE_CHANGE notify can now
6208 return NULL client_entry pointer if the CMODE was not changed
6209 by client. Application must check for this.
6211 * Added <Server ID> argument to INFO command to support server
6212 info fetching by Server ID.
6214 * Added silc_server_announce_get_channel_users to get assembled
6215 packets of channel users of the specified channel. Affected
6216 file silcd/server.[ch].
6218 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6219 was freed underneath the ID Cache.
6221 * Re-announce clients when the server received CHANNEL_CHANGE
6222 notify from the router. Affected file silcd/packet_send.c.
6224 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6226 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6227 crashed since it did not handle the fact that there is no cipher
6228 called "3" and didn't check the error condition. Now fixed.
6230 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6231 flag. It can be used to send message requests.
6233 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6235 * Implemented the RESTART command in the client.
6237 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6238 notice type messages. Added notice printing to the user
6241 * The channel keys are not re-generated if the channel's mode
6242 is PRIVKEY, ie private key on the channel exists. Affected
6243 files silcd/server.c and silcd/command.c.
6245 * Fixed a little bug in channel message delivery when channel
6246 private keys are set in the server. Affected file is
6247 silcd/packet_send.c.
6249 * Changed the setting on channel->on_channel = TRUE from the
6250 silc_client_save_channel_key to the JOIN command reply. The
6251 key payload is not received if the private channel key is set.
6252 Affected file lib/silcclient/command_reply.c and the
6253 lib/silcclient/client_channel.c.
6255 * When the CMODE_CHANGE notify is sent and the channel private
6256 key mode is removed the channel key must be re-generated in
6257 other cells as well. Added this support for the router in the
6258 silcd/packet_receive.c.
6260 * Added new local command NOTICE to send notice message on
6261 channel. Affected file silc/local_command.[ch].
6263 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6265 * Added new local command ME to the client. It is used to send
6266 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6267 some action. Affected file silc/local_command.[ch].
6269 * Changed channel_message and private_message client operations
6270 to deliver the message flags to the application. Added also
6271 the `flags' arguments to the silc_client_send_channel_message
6272 and silc_client_send_private_message functions. Affected file
6275 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6277 * Redefined the Private Message Payload to support private message
6278 keys and to support the new private message flags. Updated
6279 the protocol specs. Flags makes it possible to have for example
6280 CTCP style messages.
6282 * Added new type SilcPrivateMessagePayload and defined an API
6283 for it in the lib/silcclient/silcprivate.[ch].
6285 * Tested private message private keys successfully. Tested the
6286 private message key set, unset and list commands with the new
6289 * Redefined the Channel Message Payload to include the channel
6290 message flags (equal with private message flags) to support
6291 for example CTCP style messages.
6293 * Defined some of the message (for channel and private message)
6294 flags. Updated the protocol specs and added the flags to the
6295 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6297 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6299 * Added SilcKeyAgreementStatus type to the key agreement routines
6300 to indicate the current status and error if one occured.
6301 The status types are defined in the lib/silcclient/silcapi.h.
6303 * Added new local command KEY that is used to set and unset private
6304 keys for channels, set and unset private keys for private messages
6305 with remote clients and to send key agreement requests and
6306 negotiate the key agreement protocol with remote client. The
6307 key agreement is supported only to negotiate private message keys,
6308 it currently cannot be used to negotiate private keys for channels,
6309 as it is not convenient for that purpose.
6311 * Fixed a minor pending callback setting bug in the function
6312 silc_client_get_client_by_id_resolve, now the function works.
6313 Affected file lib/silcclient/idlist.c.
6315 * Added function silc_net_get_local_port to get local bound
6316 port by socket. Added to lib/silcutil/silcnet.[ch].
6318 * Added `sockets' and `sockets_count' fields to the SilcClient
6319 object. They hold the sockets of the listenning sockets in
6320 the client. Listenning sockets may be for example the key
6321 agreement server. Affected file lib/silcclient/client.[ch].
6322 Added functions the silc_client_add_socket and the
6323 silc_client_del_socket. They are exported to the application
6326 * Added ~./silc/clientkeys to support other client's public keys.
6328 * Renamed verify_server_key client operation to verify_public_key
6329 and added one argument to indicate the type of the connection
6330 (server, client etc.).
6332 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6334 * Added silc_server_connection_auth_request to handle the
6335 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6336 silcd/packet_receive.[ch].
6338 * Added silc_server_send_connection_auth_request into the
6339 silcd/packet_send.c to send the connection auth request packet.
6341 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6344 * Fixed the public key authentication in responder side in the
6345 server. The `auth_data' pointer includes the SilcPublicKey
6346 not the path to the public key. Affected file silcd/protocol.c.
6348 * Implemented the public key authentication in the initiator side
6349 in the server. Affected file silcd/protocol.c.
6351 * Removed the [RedirectClient] config section from the server
6352 configuration. Is not needed and I don't want to implement it.
6354 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6356 * Cleaned up the CMODE command in the server. It now works
6357 correctly and supports all the modes defined in the protocol.
6358 Affected file is silcd/command.c.
6360 * Added `hmac_name' field to the SilcChannelEntry in the server
6361 to hold the default HMAC of the channel. It can be set when
6362 creating the channel (with JOIN command). Affected files
6365 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6366 type to indicate the change of the current cipher and hmac
6367 on the channel. Client can safely ignore the <cipher> argument
6368 (if it chooses to do so) since the CHANNEL_KEY packet will
6369 force the channel key change anyway. The <hmac> argument is
6370 important since the client is responsible of setting the new
6371 HMAC and the hmac key into use.
6373 * Fixed the CMODE command in the client library as well.
6375 * Tested CMODE command in router environment successfully.
6377 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6379 * Show the version of the remote client (or server) when connecting
6380 to the server. It is logged to the log file. Affected file
6381 is silcd/protocol.c.
6383 * Fixed the KILLED notify handling in the client library. The
6384 client must be removed from all channels when receiving the
6387 Also, do not remove the client entry when giving the KILL
6388 command but when the KILLED notify is received.
6390 * Removed silc_idlist_find_client_by_nickname from the server.
6391 Not needed anymore. Affected files silcd/idlist.[ch].
6393 * Implemented the CHANNEL_CHANGE notify type handling to the
6394 server. Affected file silcd/server.c.
6398 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6400 * Added silc_server_send_notify_invite to send the INVITE
6401 notify between routers.
6403 * Implemented the INVITE command correctly to the server.
6405 * Implemented the INVITE notify type handling in the server.
6407 * Implemented the INVITE command to the client library and on the
6410 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6412 * Added function silc_server_get_client_resolve to find the
6413 client entry by ID from all ID lists and then resolve it
6414 (using WHOIS) if it cannot be found. Affected file is
6417 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6419 * Implemented the BAN command to the client library.
6421 * The JOIN command in the server now checks the invite list
6424 * Changed the silc_command_reply_payload_encode_va and the
6425 silc_command_payload_encode_va to support that if argument is
6426 NULL it ignores and checks the next argument. Affected file
6427 lib/silccore/silccommand.c.
6429 * Added silc_server_send_notify_ban to send the BAN notify
6430 type between routers.
6432 * Chaned the silc_notify_payload_encode to support that if
6433 argument is NULL it ignores and checks the next argument.
6434 Affected file lib/silccore/silcnotify.c.
6436 * Tested ban lists in router environment successfully.
6438 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6440 * Implemented BAN command to the server, in silcd/command.[ch].
6442 * Removed the BAN and INVITE_LIST modes from the CMODE command
6445 * Added function silc_string_match to regex match two strings.
6446 Affected files lib/silcutil/silcutil.[ch].
6448 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6450 * Redefined parts of the SilcChannelEntry in the server to support
6451 the new ban and invite lists.
6453 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6455 * Redefined the INVITE command. The same command can be used to
6456 invite individuals to the channel but also to manage the invite
6457 list of the channel (to add to and remove from the invite list).
6458 Updated the protocol specs.
6460 * Added new command SILC_COMMAND_BAN that can be used to manage
6461 the ban list of the channel. Updated the protocol specs.
6463 * Removed the channel modes: the SILC_CMODE_BAN and the
6464 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6465 in the CMODE command. The equivalent features are now available
6466 using INVITE and BAN commands. Updated the protocol specs.
6468 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6469 in the network about change in the current ban list. The notify
6470 type is not used by the client.
6472 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6473 support the invite lists.
6475 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6477 * Added new function silc_string_regexify that converts string
6478 including wildcard characters into regex string that can
6479 be used by the GNU regex library. Added into the file
6480 lib/silcutil/silcutil.[ch].
6482 Added silc_string_regex_combine to combine to regex strings
6483 into one so that they can be used as one regex string by
6484 the GNU regex library. Added into the file
6485 lib/silcutil/silcutil.[ch].
6487 Added silc_string_regex_match to match two strings. It returns
6488 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6490 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6492 * Imported GNU regex to the soruce tree into lib/contrib.
6493 Fixed some compiler warning from the regex.c.
6495 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6497 * Fixed MOTD command in the server to work in router environment.
6499 * Fixed the MOTD command in the client library to support
6500 the server argument in the command.
6502 * Added `nickname_len' argument to the silc_idlist_add_client
6503 in the server, as the `nickname' argument may be binary data
6506 * Added silc_idlist_get_channels to return all channels from
6509 * Implemented LIST command to the server. Affected file is
6512 * Implemented the LIST command to the client library and on the
6515 * Added [<user count>] argument to the LIST command reply.
6516 With private channels the user count is not shown.
6518 * Updated TODO and README.
6520 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6522 * The client entry's data.registered must be TRUE even with
6523 global client entry on global client list. The data.registered
6524 is used to check whether the client is anymore in the network,
6525 for example with WHOWAS command so it must be valid.
6527 * Fixed the WHOWAS command in the server. It now actually works
6528 in router environment. Added function into silcd/command_reply.c
6529 silc_server_command_reply_whowas_save.
6531 * Added silc_idlist_purge function to the silcd/idlist.c
6532 to periodically purge the ID Cache.
6534 * Fixed INFO command in the server. It works now in router
6535 environment. Added <server name> argument to the INFO command
6536 reply. Updated the protocol specs.
6538 * Fixed minor bug in silc_idcache_purge to not purge if the
6539 expire value is zero.
6541 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6542 they were buggy because of the WHOWAS information.
6544 * Fixed local command MSG to handle the async resolving of
6545 the remote client properly. It used to fail the first MSG.
6546 Affected file silc/local_command.c.
6548 * Added `data_len' field to SilcIDCache context.
6550 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6552 * Update TODO. Todo in commands in the server.
6554 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6556 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6557 used by routers as broadcast packet to inform other routers
6558 about the changed user mode.
6560 Implemented the notify handling in the server. Affected file is
6561 silcd/packet_receive.c. Added the function
6562 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6564 * Added new generic Channel Payload and deprecated the New Channel
6565 Payload. The New Channel Payload is now the generic Channel
6568 * Added new argument `mode' to the silc_server_send_new_channel
6569 as it is required in the Channel Payload now.
6571 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6572 and created a new and real SilChannelPayload to represent the
6573 new generic Channel Payload. Implemented the encode/decode
6574 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6576 * Added silc_server_get_client_channel_list to return the list
6577 of channels the client has joined for WHOIS command reply.
6578 Affected file silcd/server.[ch].
6580 * Implemented the channel list sending in the WHOIS command reply
6581 in server and in the client.
6583 Implemented the channel list displaying on the user interface
6584 as well. Affected file silc/client_ops.c.
6586 * Added silc_channel_payload_parse_list to parse list of Channel
6587 Payloads. It returns SilcDList list of SilcChannelPayloads.
6588 Client for example can use this function to parse the list of
6589 channels it receives in the WHOIS command reply. The caller
6590 must free the list by calling silc_channel_payload_list_free.
6591 Affected files lib/silccore/silcchannel.[ch].
6593 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6595 * Added one new argument <user mode> to the WHOIS command reply
6596 to return the mode of the user in SILC. Updated the protocol
6599 Implemented it to the server and client.
6601 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6603 * Fixed the mode printing on the user interface on joining.
6604 Affected file silc/client_ops.c.
6606 * Implemented the UMODE command and user modes in general to the
6607 client library and to the user interface.
6609 * Implemented the UMODE command to the server.
6611 * The server now sends UNKNOWN_COMMAND error status if client sends
6612 unknown command. Affected file silcd/command.c.
6614 * All server commands now handle the command identifier the right
6615 way when sending the command reply to the client. The client can
6616 use to identify the command replies with the identifier.
6618 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6620 * Added silc_server_get_client_route to resolve the route to
6621 the client indicated by the client ID. Affected file is
6624 * Added silc_server_relay_packet as general function to relay
6625 packet to arbitrary destination. This deprecates functions
6626 like _send_private_message_key, _relay_notify etc. Affected
6627 file is silcd/packet_send.[ch].
6629 Removed silc_server_send_key_agreement,
6630 silc_server_send_private_message_key and
6631 silc_server_packet_relay_notify functions from the file
6632 silcd/packet_send.[ch].
6636 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6637 server. Affected file silcd/packet_receive.[ch].
6639 * Implemented the KILL command to the client. Implemented the
6640 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6641 Affected files lib/silcclient/command[_reply].c and
6642 lib/silcclient/client_notify.c. Implemented the KILL notify
6643 printing in the user inteface.
6645 * Fixed a lot silc_parse_nick memory leaks from the client
6646 library in the file lib/silcclient/command.c.
6648 * Changed the silc_server_send_notify_on_channels's `sender'
6649 argument from SilcSocketConnection to SilcClientEntry to
6650 check the sender as entry and not as connection object and not
6651 to send to the client provided as argument. The affected file
6652 is silcd/packet_send.[ch].
6654 * The notify packets that are destined directly to the client used
6655 to not to be processed by the server. Now changed that and the
6656 server processes all notify packets. After relaying the packet
6657 to the client the notify packet is processed in the server.
6659 * The silc_server_free_client_data now checks whether there is
6660 pending outgoing traffic for the client and purges the data to
6661 the network before removing the client entry.
6663 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6665 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6666 an client is killed from the SILC Network. Updated the protocol
6669 Added new function silc_server_send_notify_killed to the
6670 silcd/packet_send.[ch].
6672 * Added function silc_server_packet_relay_notify to relay notify
6673 packets that are destined directly to a client. In this case
6674 the server does not process the notify packets but merely relays
6675 it to the client. Affected file silcd/packet_send.[ch].
6677 Added also silc_server_packet_process_relay_notify to check
6678 whereto relay the notify. Affected file is
6679 silcd/packet_receive.[ch].
6681 * Implemented the KILL command to the server.
6685 * Added the backup schema desgined last fall to the protocol
6686 specs for everyone to see. The specification is in the
6687 *-spec-xx.txt draft and the packet type definitions for the
6688 backup routers is in *-pp-xx.txt draft. Thusly, added also
6689 new packet type SILC_PACKET_CELL_ROUTERS.
6691 * A big security problem in the implementation discovered. The
6692 signoff of an client did not cause new channel key generation
6693 which it of course should've done. The channel keys must be
6694 always re-generated when client leaves (or signoffs) the channel.
6695 The silc_server_remove_from_channels funtion now handles
6696 the channel key re-generation.
6698 * Added `sender' argument to the silc_server_send_notify_on_channels
6699 to not to send the client provided as argument. Affected file
6700 silcd/packet_send.[ch].
6702 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6704 * Implemented OPER and SILCOPER commands into the server and
6707 * Added silc_auth_verify and silc_auth_verify_data to verify
6708 the authentication directly from the authentication payload.
6709 It supports verifying both passphrase and public key based
6710 authentication. Affected file lib/silccore/silcauth.[ch].
6712 * Added `hash' field to the SilcIDListData structure. It is the
6713 hash negotiated in the SKE protocol. Affected file is
6716 * Slight redesigning of the SilcAuthPayload handling routines.
6717 Do not send SilcPKCS but SilcPublicKey as argument.
6719 * Implemented the public key authentication support to the
6720 serverconfig. The public key is loaded from the provided path
6721 and saved as authentication data to void * pointer. Thus,
6722 changed the unsigned char *auth_data to void *auth_data;
6724 * Fixed SHUTDOWN command to send the reply before the server
6725 is shutdown. :) Affected file silcd/command.c.
6727 * Fixed fatal bug in CONNECT command. The hostname was invalid
6728 memory and server crashed. Affected file silcd/command.c.
6730 * Fixed fatal bug in CLOSE command. The server_entry became
6731 invalid but was referenced later in the command. Affected file
6734 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6736 * Fixed fatal bug in failure packet handling. Server ignored
6737 the failure and thus crashed when it came.
6741 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6743 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6744 that the command may be executed only once in (about) 2 seconds.
6745 The old SILC_CF_LAG flag is same but allows command bursts up
6746 to five before limiting.
6748 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6749 server code. Various commands now includes the CF_LAG_STRICT
6750 flag to disallow any kind of miss-use of the command.
6752 * Fixed the silc_buffer_unformat to not to allocate any data
6753 if the length of the data is zero. It used to allocate the
6754 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6756 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6758 * Changed the format of AdminConnection configuration section
6759 in the server. Added username of the admin to the format.
6760 Affected files silcd/serverconfig.[ch].
6762 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6763 to return admin configuration data by host, username and/or
6766 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6768 * Implemented WHOWAS command to the server. Added the functions:
6770 silc_server_command_whowas_parse,
6771 silc_server_command_whowas_send_reply,
6772 silc_server_command_whowas_from_client and
6773 silc_server_command_whowas_from_server
6775 * Added <Client ID> argument to the WHOWAS command reply. Updated
6776 the protocol specs accordingly.
6778 * Implemented WHOWAS command and command_reply to the client
6781 Implemented the WHOWAS printing on the user interface.
6783 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6785 * Added new argument to the WHOWAS command reply, the real name.
6786 It is an optional argument. Updated the protocol specs.
6788 * Added SilcIDCacheDestructor callback that is registered when
6789 the SilcIDCache is allocated. The callback is called when
6790 an cache entry in the ID Cache expires, or is purged from the
6791 cache. Added into lib/silccore/idcache.[ch].
6793 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6794 to destruct the client entries when the cache entry expires.
6795 Other ID Cache's in server and in the client library ignores
6798 * If the ID Cache entry's `expire' field is zero then the entry
6799 never expires. Added boolean `expire' argument to the
6800 silc_idcache_add function in the lib/silccore/idcache.[ch].
6801 If it is TRUE the default expiry value is used.
6803 * Added silc_server_free_client_data_timeout that is registered
6804 when client disconnects. By default for 5 minutes we preserve
6805 the client entry for history - for WHOWAS command.
6807 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6809 * Added support to the server to enforce that commands are not
6810 executed more than once in 2 seconds. If server receives
6811 commands from client more frequently, timeout is registered
6812 to process the commands. Affected file silcd/command.c.
6813 Added new function silc_server_command_process_timeout.
6815 * Changed NICK_NOTIFY handling in client library to check that
6816 if the client's nickname was changed, so there is no need to
6817 resolve anything from the server.
6819 * Removed error printing from the WHOIS and IDENTIFY commands.
6820 If error occurs then it is ignored silently in the client library.
6821 The application, however, may map the received error to
6822 human readable error string. The application currently maps
6823 the NO_SUCH_NICKNAME error to string.
6825 * Made the command status message public to the application. Moved
6826 them from lib/silcclient/command_reply.c to
6827 lib/silcclient/command_reply.h. The application can map the
6828 received command status to the string with the
6829 silc_client_command_status_message function.
6831 * Added check to the server to check that client's ID is same
6832 as the Source ID in the packet the client sent. They must
6835 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6837 * Added dist-bzip hook to the Makefile.am to make bzip2
6838 compressed distributions.
6840 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6842 * Server now enforces the maximum length for the nickname and
6843 the channel as protocol specification dictates. 128 bytes for
6844 nickname and 256 bytes for channel name.
6846 * Moved the WHOIS printing to the application. The client libary
6847 does not print out the WHOIS information anymore, the application
6848 must do it. Renamed silc_client_command_reply_whois_print to
6849 the silc_client_command_reply_whois_save.
6851 The client's idle time is also sent to the application now, and
6852 the idle is shown on screen.
6854 * Added silc_client_command_reply_identify_save to save the
6855 received IDENTIFY entries.
6857 * Do not check for channel private keys in message sending and
6858 reception if the channel does not have the PRIVKEY mode set.
6859 Affected file lib/silclient/client_channel.c.
6861 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6863 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6864 just surfaced after chaning the JOIN procedure.
6866 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6868 * Added silc_client_get_clients_by_list to get client entries
6869 from Client ID list, that is returned for example by JOIN
6870 and USERS command replies. The application should use this
6871 function for example when JOIN command reply is received to
6872 resolve the clients already on the channel (library does not
6873 do that anymore as USERS command reply is not used in the JOIN
6874 procedure anymore). Affected files lib/silcclient/silcapi.h and
6875 lib/silcclient/idlist.c.
6877 * JOIN command reply and USERS command reply returns now SilcBuffer
6878 pointers instead of unsigned char pointers when returning
6879 the client list and mode list.
6881 * Added <Client ID> argument to the JOIN command reply, mainly
6882 for the server to identify for which client the command was
6883 originally sent. Updated protocol specs accordingly.
6885 * Added SilcDlist private_key pointer to the SilcChannelEntry
6886 in the client to support the channel private keys. Affected
6887 file is lib/silcclient/idlist.h.
6889 * Added SilcChannelPrivateKey argument to the function
6890 silc_client_send_channel_message so that application can choose
6891 to use specific private ke if it wants to. If it is not provided,
6892 the normal channel key is used, unless private keys are set.
6893 In this case the first (key that was added first) is used
6894 as the encryption key.
6896 * Implemented the support for channel private key handling.
6897 Implemented the following functions:
6899 silc_client_add_channel_private_key,
6900 silc_client_del_channel_private_keys,
6901 silc_client_del_channel_private_key,
6902 silc_client_list_channel_private_keys and
6903 silc_client_free_channel_private_keys
6905 Affected file lib/silcclient/client_channel.c.
6907 * Added the support for the private keys in the channel message
6908 sending and encryption and in the message reception and
6909 decryption. Affected funtions are
6910 silc_client_send_channel_message and silc_client_channel_message.
6912 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6914 * Added SKE's key verify callback to the client library's
6915 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6917 * Removed the statement that server (or router) must send USERS
6918 command reply when joining to the channel so that the client
6919 knows who are on the channel. Instead, the client list and
6920 client's mode list is now sent in the JOIN command reply to the
6921 client who joined channel. This is better solution.
6923 * Added function silc_server_get_users_on_channel and function
6924 silc_server_save_users_on_channel to the silcd/server.[ch].
6926 * Removed function silc_server_command_send_users from the
6929 * Do not show topic on the client library anymore. The topic is
6930 sent in the command reply notify to the application and the
6931 application must show the topic now.
6933 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6935 * Added client searching by nickname hash into the IDENTIFY and
6936 WHOIS commands in the server as they were clearly missing from
6937 them. Affected file is silcd/command.c.
6939 * Fixed a bug in private message receiving in the client library.
6940 The remote ID was freed and it wasn't supposed, now it is
6943 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6945 * Minor fix to the channel payload; allocate the data area, as it
6946 needs to be of specific length.
6948 * If the key agreement port is zero then the operating
6949 system will define the bound port. Affected files are
6950 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6952 * Added new function silc_channel_payload_decrypt into the file
6953 lib/silccore/silcchannel.[ch].
6955 * Moved the channel message etc, check from silc_packet_decrypt
6956 to applications. The library calls now a generic
6957 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6958 when the packet is either normal or special. This was done to
6959 allow more wide range of checking that was not allowed when
6960 the code was in library. Now applications can do virtually any
6961 checks to the packet and return to the library the decision how
6962 the packet should be processed. Affected files are
6963 lib/silccore/silcpacket.[ch].
6965 Added silc_server_packet_decrypt_check to the server and
6966 silc_client_packet_decrypt_check to the client library.
6968 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6969 to send with specified source and destination information.
6971 * Channel message delivery between routers was broken after the
6972 channel key distribution was fixed earlier. The channel key
6973 was used be to distributed to other routers as well which is not
6974 allowed by the protocol. Now this is fixed and channel keys
6975 really are cell specific and the channel message delivery between
6976 routers comply with the protocol specification.
6978 * Fixed various commands in server to check also the global list
6979 for the channel entry and not just the local list. The affected
6980 file silcd/command.c.
6982 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6984 * Added assert()s to buffer formatting and unformatting routines
6985 to assert (if --enable-debug) when error occurs. Affected
6986 file: lib/silcutil/silcbuffmt.c.
6988 * Changed to auto-reconnect to check whether the remote host is
6989 router and register the re-connect timeout if it is. It used
6990 to check that whether we are normal server, but router must do
6991 auto-reconnect with another router as well. Affected file
6994 * Removed the [<key len>] option from CMODE command as the cipher
6995 name decides the key length, nowadays. See the defined ciphers
6996 from the protocol specification.
6998 * Added [<hmac>] option to the CMODE command to define the HMAC
6999 for the channel. Added SILC_CMODE_HMAC channel mode.
7001 * Added [<hmac>] option for the JOIN command so that user can
7002 select which HMAC is used to compute the MACs of the channel
7005 * Added Hmac field to the Channel Message Payload. The integrity
7006 of plaintext channel messages are now protected by computing
7007 MAC of the message and attaching the MAC to the payload. The
7008 MAC is encrypted. Now, it is clear that this causes some
7009 overhead to the size of the packet but rationale for this is that
7010 now the receiver can verify whether the channel message decrypted
7011 correctly and also when private keys are set for the channel the
7012 receiver can decrypt the packet with several keys and check from
7013 the MAC which key decrypted the message correctly.
7015 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7016 lib/silccrypt/silccipher.[ch].
7018 * Added silc_hash_len to return the digest length into the
7019 lib/silcrypt/silchash.[ch].
7021 * Rewrote parts of Silc Channel Payload interface in the
7022 lib/silccore/silcchannel.[ch]. The encode function now also
7023 encrypts the packet and parse function decrypts it.
7025 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7027 * Fixed a minor formatting bug in the SKE's key material processing.
7028 It actually might have processed the keys wrong way resulting
7031 * Redefined the mandatory HMAC algorithms and added new algorithms.
7032 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7033 and hmac-md5 truncated to 96 bits. The mandatory is now
7034 hmac-sha1-96. Rest are optional (including the one that used
7035 to be mandatory). Rationale for this is that the truncated HMAC
7036 length is sufficient from security point of view and can actually
7037 make the attack against the HMAC harder. Also, the truncated
7038 HMAC causes less overhead to the packets. See the RFC2104 for
7041 * Added new [hmac] configuration section. The SKE used to use
7042 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7043 is of course wrong. The official names that must be proposed in
7044 the SKE are the ones defined in the protocol specification
7045 (hmac-sha1-96 for example). The user can configure any hmac
7046 using any hash function configured in the [hash] section. At
7047 least, the mandatory must be configured.
7049 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7051 * Added HMAC list to the SKE proposal list. It has now both
7052 hash algorithm list and HMAC list. This makes the protocol
7053 incompatible with previous versions. The SKE now seems to work
7054 the way it is supposed to work, for the first time actually.
7056 * Defined plain Hash algorithms to the protocol specification.
7059 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7061 * Implemented support for key agreement packets into the server.
7062 Added functions silc_server_key_agreement and
7063 silc_server_send_key_agreement. Other than these functions,
7064 server has nothing to do with this packet.
7066 * Added support for private message key packets into the server.
7067 Added functions silc_server_private_message_key and
7068 silc_server_send_private_message_key.
7072 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7073 called in the protocol's final callback instead in the END
7074 protocol state. This makes a little more sense and in the same
7075 time in client we can use the same protocol routines for normal
7076 key exchange and to key agreement packet handling as well.
7078 * Added to both client's and server's KE protocol context the
7079 SilcSKEKeyMaterial pointer to save the key material. We will
7080 bring the key material to the protocol's final callback by doing
7081 this. The final callback must free the key material.
7083 * Added SKE's packet_send callback into client's KE protocol
7084 context so that the caller can choose what packet sending function
7085 is used. This way we can use different packet sending when
7086 doing normal SKE when doing key agreement packet handling (in
7087 the key agreement packet handling we do not want to encrypt
7090 * Implemented the responder side of the key agreement routines
7091 in the client. The client can now bind to specified port and
7092 accept incoming key negotiation. The key material is passed
7093 to the application after the protocol is over.
7095 * Implemented the processing of incoming Key Agreement packet
7096 in the client. Added function silc_client_key_agreement to
7099 * Implemented the intiator side of the key agreement routines
7100 in the client. The client can now initiate key agreement with
7101 another remote client. The key material is passed to the
7102 application after the protocol is over.
7104 * Created client_keyagr.c to include all the key agreement
7107 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7108 SILC_TASK_CALLBACK except that it is not static.
7110 * Created client_notify.c and moved the Notify packet handling
7111 from the client.[ch] into that file.
7113 * Created client_prvmsg.c and moved all private message and
7114 private message key routines from the client.[ch] into that file.
7116 * Create client_channel.c and moved all channel message and
7117 channel private key routines from the client.[ch] into that file.
7119 * Changed silc_client_get_client_by_id_resolve to resolve with
7120 WHOIS command instead of IDENTIFY command, in the file
7121 lib/silclient/idlist.c.
7123 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7125 * Implemented the SKE's responder side to the Client library.
7127 * When FAILURE is received to the protocol do not trust it
7128 blindly. Register a timeout to wait whether the remote closes
7129 the connection as it should do it, only after that process the
7130 actual failure. This was changed to both client and server.
7132 * Added client_internal.h to include some of the structures
7133 there instead of client.h in lib/silcclient/.
7135 * Added function silc_task_unregister_by_callback to unregister
7136 timeouts by the callback function.
7138 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7140 * Some "Incomplete WHOIS info" errors has been appearing on the
7141 log files. Took away the entry->userinfo check from WHOIS
7142 reply sending. The entry->userinfo is now " " if client did not
7143 provide one. I thought this was fixed earlier but something
7144 is wrong still. Let's see if the error still appears.
7146 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7148 * Fixed a minor bug in the login when the channel key is
7149 re-generated in the server. It used to generate the key in
7150 wrong order and thus caused problems in the channel traffic.
7152 * Fixed a minor bug in channel key distsribution after
7153 KICK command. The key was not sent to the router even though
7156 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7158 * Added silc_ske_process_key_material_data as generic routine
7159 to process any key material as the SILC protocol dictates. The
7160 function is used by the actual SKE library but can be used by
7161 applications as well. This relates to the private message keys
7162 and the channel private keys since they must be processed the
7163 same way the normal SILC session keys. The protocol dictates
7164 this. Affected files: lib/silcske/silcske.[ch].
7166 Added also silc_ske_free_key_material to free the
7167 SilcSKEKeyMaterial structure.
7169 * Defined silc_cipher_set_key function to set the key for
7170 cipher without using the object's method function. The affected
7171 files: lib/silccrypt/silccipher.[ch].
7173 * Implemented silc silc_client_add_private_message_key,
7174 silc_client_add_private_message_key_ske,
7175 silc_client_del_private_message_key,
7176 silc_client_list_private_message_keys and
7177 silc_client_free_private_message_keys functions in the
7180 Added functions silc_client_send_private_message_key to send
7181 the Private Message Key payload and silc_client_private_message_key
7182 to handle incoming Private Message Key payload.
7184 * Added Cipher field to the Private Message Key payload to set
7185 the cipher to be used. If ignored, the default cipher defined
7186 in the SILC protocol (aes-256-cbc) is used.
7188 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7190 * Removed lib/silcclient/ops.h file.
7192 Redefined parts of the SILC Client Library API. Created new
7193 file silcapi.h that deprecates the ops.h file and defines the
7194 published Client Library API. Defined also private message key
7195 API and channel private key API into the file.
7197 This is the file that the application must include from the
7198 SILC Client Library. Other files need not be included by
7199 the application anymore.
7201 * Added new key_agreement client operation callback and also
7202 defined the Key Agreement library API for the application.
7204 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7206 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7207 is used by clients to request key negotiation between another
7208 client in the SILC network. If the negotiation is started it
7209 is performed using the SKE protocol. The result of the
7210 negotiation, the secret key material, can be used for example
7211 as private message key.
7213 Implemented the Key Agreement payload into the files
7214 lib/silccore/silauth.[ch].
7216 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7218 * Redefined ciphers for the SILC protocol. Added some new ciphers
7219 and defined the key lengths for the algorithms. Changed the
7220 code accordingly. The default key length is now 256 bits.
7222 * Fixed SKE key distribution function silc_ske_process_key_material
7223 when the key length is more than 128 bits. The default key
7224 length in SILC is now 256 bits.
7226 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7227 to indicate unsupported algorithm.
7229 * Renamed rijndael.c to aes.c and all functions as well.
7231 * Fixed a long standing channel key setting bug in client library.
7232 Weird that it has never surfaced before.
7234 * Fixed bug in channel deletion. If the entire channel is removed
7235 then it must also delete the references of the channel entry
7236 from the client's channel list as the client's channel entry and
7237 the channel's client entry share same memory.
7239 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7241 * Implemented CONNECT and SHUTDOWN commands in the client.
7243 * Implemented CLOSE command to the client.
7245 * Added the function silc_idlist_find_server_by_name into the
7246 files silcd/idlist.[ch].
7248 Added the function silc_idlist_find_server_by_conn into the
7249 files silcd/idlist.[ch].
7251 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7253 * DIE command was renamed to SHUTDOWN. Updated the both code
7256 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7257 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7259 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7262 * Added function silc_server_create_connection function to create
7263 connection to remote router. My server implementation actually
7264 does not allow router to connect to normal server (it expects
7265 that normal server always initiates the connection to the router)
7266 so the CONNECT command is only good for connecting to another
7269 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7271 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7272 or some other client was kicked from the channel.
7274 Implemented the handling of the notify type to both client
7277 Implemented silc_server_send_notify_kicked to send the KICKED
7278 notify. It is used to send it to the server's primary router.
7280 * Implemented the KICK command into server and client.
7282 * Added `query' argument to the silc_idlist_get_client function
7283 to indicate whether to query the client from server or not if
7286 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7287 to indicate that the client is not channel founder.
7291 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7293 * Removed the rng context from SilcPacketContext structure and
7294 changed that the packet routine uses the Global RNG API.
7296 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7298 * Added support for quit message that client can "leave" on the
7299 channel when it quits the SILC. It is ditributed inside the
7300 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7302 Added silc_server_free_client_data that will take the
7303 signoff message as argument.
7305 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7307 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7309 * Updated parts of the protocol specification to keep it up
7312 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7314 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7315 payloads in one packet.
7317 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7318 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7319 use now the new List flag.
7321 * Also deprecated the following packet types: REPLACE_ID,
7322 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7324 * Added list support for Notify packet in server.
7326 * Added silc_server_send_notify_channel_change to send the
7327 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7328 the silc_server_send_replace_id.
7330 * Added silc_server_send_notify_nick_change to send the
7331 NICK_CHANGE notify type. Deprecates the function
7332 silc_server_send_replace_id.
7334 * Added silc_server_send_notify_join to send the JOIN notify type.
7335 Deprecates the function silc_server_send_new_channel_user.
7337 * Added silc_server_send_notify_leave to send LEAVE notify type.
7338 Deprecates the function silc_server_send_remove_channel_user.
7340 * Added silc_server_send_notify_cmode and
7341 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7342 types. Deprecates the silc_server_send_set_mode function.
7344 * Added SERVER_SIGNOFF notify type to indicate that server has
7345 quit. This means that all clients on the channel from that
7346 server will drop. This can be also used when netsplit happens.
7348 Deprecated REMOVE_ID packet type since it is not needed anymore
7351 Added silc_server_send_notify_server_signoff to send the
7352 SERVER_SIGNOFF notify type. Deprecates the function
7353 silc_server_send_remove_id.
7355 Added also silc_server_send_notify_signoff to send the
7356 SIGNOFF notify type.
7358 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7359 SILC protocol from this day on. Changed the protocol
7360 specification as well.
7362 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7363 notify type. It is used between routers to notify about
7364 topic changes on a channel.
7366 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7369 * Partly updated the protocol specification to comply with the
7370 changes now made. It is still though a bit outdated.
7372 * The JOIN notify type now takes one extra argument <Channel ID>.
7373 The packet used to be destined to the channel but now the
7374 JOIN type may be sent as list thus it is impossible to
7375 destine it to any specific channel. By adding this argument
7376 it is again possible.
7378 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7380 * Added CREDITS file. The CHANGES and CREDITS file will appear
7381 in the distribution as well.
7383 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7385 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7386 types in the server's silcd/packet_receive.c.
7388 * Implemented CMODE and CUMODE to work in router environment.
7390 * Fixed minor encoding and decoding buglet from the
7391 lib/silccore/silcmode.c.
7393 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7396 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7398 * Changed all SilcConfigServer* and silc_config_server* to
7399 SilcServerConfig* and silc_server_config*, respectively.
7402 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7404 * Associated the ID (client or server ID) to the Authentication
7405 Payload to avoid any possibility of forging. Updated the
7406 protocol specification and the code accordingly.
7408 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7410 * The RSA key length is now save to the RsaKey context in the
7411 key generation process in lib/silccrypt/rsa.c. The key length
7412 is now used to figure out the maximum size of the block allowed
7413 to be encrypted/signed.
7415 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7416 is equivalent to the silc_mp_mp2bin but does not allocate any
7419 * Changed silc_mp_mp2bin API to take length argument. If it is
7420 non-zero then the buffer is allocated that large. If zero, then
7421 the size is approximated using silc_mp_sizeinbase, which however
7424 * Created Global RNG API which is global RNG that application can
7425 initialize. After initializing, any routine anywhere in the
7426 code (including library) can use RNG without allocating a new
7427 RNG object. This was done to allow this sort of use of the
7428 RNG in code that has no chance to allocate RNG object. All
7429 applications currently allocate this and many routines in the
7430 library use this. Affected file lib/silccrypt/silcrng.[ch].
7432 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7433 it to use the Global RNG API.
7435 * Defined Authentication Payload into protocol specification that
7436 is used during SILC session to authenticate entities. It is
7437 used for example by client to authenticate itself to the server
7438 to obtain server operator privileges.
7440 Implemented this payload into the lib/silccore/silcauth.[ch].
7441 Implemented also routines for public key based authentication
7442 as the new protocol specification dictates.
7444 Moved definitions of different authentication methods from
7445 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7447 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7448 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7449 silc_pkcs_verify_with_hash functions into the file
7450 lib/silccrypt/silcpkcs.[ch].
7452 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7454 * The client entry's userinfo pointer must be always valid.
7455 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7456 will fail since it requires the userinfo. Now, the userinfo
7457 is allocated as "" if actual userinfo does not exist. Actually,
7458 it must exist and it is totally Ok to drop client connections
7459 that does not announce the userinfo. However, we will make
7460 this workaround for now.
7462 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7463 to return the remote port by socket.
7465 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7467 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7468 SILC_SERVER_PENDING_EXEC and added an new macro
7469 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7470 data or when error occurs while processing the pending command.
7472 Added new argument `destructor' into silc_server_command_pending
7473 and to the SilcServerCommandPending object. This destructor is
7474 now called after calling the pending callback or if error occurs
7475 immediately. If error occurs the actual pending callback won't
7476 be called at all - only the destructor. The destructor may be
7477 NULL if destructor is not needed.
7479 All this applies for client library code as well. Similar
7480 changes were made there as well for the pending commands.
7482 In the client, the application must now allocate the
7483 SilcClientCommandContext with the silc_client_command_alloc
7486 * Added reference counter to the SilcServerCommandContext. Added
7487 function silc_server_command_alloc and silc_server_command_dup
7490 Same type of functions added to the client library for the same
7493 * Removed the cmd_ident from IDListData away since it is now
7494 global for all connections. It is the command identifier used
7495 in command sending and with pending commands. The affected file
7498 * Added reference counter to the SilcSocketConnection objecet to
7499 indicate the usage count of the object. The object won't be
7500 freed untill the reference counter hits zero. Currently only
7501 server uses this, and client ignores it. The client must be
7502 set to use this too later. The affected files are
7503 lib/silccore/silcsockconn.[ch]. Added also the function
7504 silc_socket_dup to increase the reference counter.
7506 This was mainly added because it is possible that the socket
7507 is removed underneath of pending command or other async
7508 operation. Now it won't be free'd and proper DISCONNECTING
7509 flags, etc. can be set to avoid sending data to connection that
7510 is not valid anymore.
7512 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7513 the connection. After that it sets SILC_SET_DISCONNECTED.
7514 It is, however, possible that the socket data is not still freed.
7515 The silc_server_packet_process now checks that data is not
7516 read or written to connection that is DISCONNECTED. The socket
7517 get's freed when the reference counter hits zero.
7519 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7521 * Changed the client operation API: channel_message operation's
7522 `sender' is now the client entry of the sender, not the nickname
7523 and the `channel' is the channel entry, not the channel name.
7525 In the private_message operation the `sender' is now also the
7526 client entry of the sender not the nickname.
7528 Affected file is lib/silcclient/ops.h and all applications
7529 using the client operations.
7531 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7533 * Moved the calling of ops->connect() from connect_to_server_final
7534 into receive_new_id functin since that is the point when the
7535 client is actually allowed to send traffic to network. The
7536 affected file is lib/silcclient/client.c.
7538 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7540 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7541 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7542 (if needs broadcasting) instead of broadcasting the packets one
7543 by one which would make a burst in the network traffic.
7545 * Added `broadcast' argument to the functions in silcd/server.[ch]
7546 silc_server_create_new_channel[_with_id] to indicate whether
7547 to send New Channel packet to primary router.
7549 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7551 * Added new function into the silcd/server.[ch] files:
7552 silc_server_create_new_channel_with_id to create new channel with
7553 already existing Channel ID.
7555 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7556 lib/silccore/silcpacket.h. This packet is used t send list of
7557 Set Mode payloads inside one packet. Server uses this to set
7558 the modes for the channels and clients on those channels, that it
7559 announced to the router when it connected to it. The protocol
7560 specification has been updated accordingly.
7562 * The silc_server_new_channel did not handle the packet coming
7563 from normal server as it normally does not send that. However,
7564 when it announces its channels it does send it. Implemented
7565 the support for that.
7567 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7568 into the file lib/silccore/id.h.
7570 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7572 * Fixed memory leaks in the functions silc_idlist_del_client,
7573 silc_idlist_del_channel and silc_idlist_del_server in the file
7574 silcd/idlist.c. All of those leaked like a sieve.
7576 * Fixed some small memory leaks in the client's function
7577 silc_client_notify_by_server.
7579 * Added functions into silcd/server.c: silc_server_announce_clients,
7580 silc_server_announce_channels and silc_server_announce_server.
7581 These functions are used by normal and router server to announce
7582 to its primary router about clients, channels and servers (when
7583 router) that we own. This is done after we've connected to the
7586 These functions effectively implements the following packet types:
7587 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7588 and SILC_PACKET_NEW_ID_LIST.
7590 * Added new functions into the silcd/packet_receive.[ch]:
7591 silc_server_new_id_list, silc_server_new_channel_list and
7592 silc_server_new_channel_user_list to handle the incoming
7593 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7595 * Added support of changing Channel ID in the function
7596 silc_server_replace_id. If the server that announces a channel
7597 to the router already exists in the router (with same name but
7598 with different Channel ID), router is responsible to send
7599 Replace ID packet to the server and force the server to change
7600 the Channel ID to the one router has.
7602 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7603 client that the Channel ID has been changed by the router. The
7604 normal server sends this to the client. Client must start using
7605 the new Channel ID as the channel's ID.
7607 Implemented handling of this new type into lib/silcclient/client.c
7608 into the function silc_client_notify_by_server.
7610 * Added new function silc_idlist_replace_channel_id into the files
7611 silcd/idlist.[ch] to replace the Channel ID.
7613 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7615 * Call silc_server_command_identify_check always when processing
7616 the IDENTIFY command in silcd/command.c
7618 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7620 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7621 send keepalive packets. The packet can be sent by clients,
7622 servers and routers.
7624 Added function silc_socket_set_heartbeat into the file
7625 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7626 If not set, the heartbeat is not performed. The actual
7627 heartbeat is implemented in the low level socket connection
7628 library. However, application is responsible of actually
7631 Added silc_server_send_heartbeat to send the actual heartbeat
7632 packet into silcd/packet_send.[ch]. Server now performs
7633 keepalive with all connections.
7635 * Added silc_task_get_first function into lib/silcutil/silctask.c
7636 to return the timeout task with shortest timeout. There was a bug
7637 in task unregistration that caused problems. TODO has been
7638 updated to include that task system must be rewritten.
7640 * The client library will now resolve the client information when
7641 receiving JOIN notify from server for client that we know but
7642 have incomplete information.
7644 * Rewrote parts of silc_server_remove_from_channels and
7645 silc_server_remove_from_one_channel as they did not remove the
7646 channel in some circumstances even though they should've.
7648 * Encryption problem encountered in server:
7650 The LEAVE command used to send the Channel Key packet to the
7651 router immediately after generating it. However, the code
7652 had earlier sent Remove Channel user packet but not immediately,
7653 ie. it was put to queue. The order of packets in the router
7654 was that Channel Key packet was first and Remove Channel User
7655 packet was second, even though they were encrypted in the
7656 reverse order. For this reason, MAC check failed. Now, this
7657 is fixed by not sending the Channel Key packet immediately but
7658 putting it to queue. However, this is more fundamental problem:
7659 packets that are in queue should actually not be encrypted
7660 because packets that are sent immediately gets encrypted
7661 actually with wrong IV (and thus MAC check fails). So, packets
7662 that are in queue should be encrypted when they are sent to
7663 the wire and not when they put to the queue.
7665 However, the problem is that the current system has not been
7666 designed to work that way. Instead, the packet is encrypted
7667 as soon as possible and left to the queue. The queue is then
7668 just purged into wire. There won't be any fixes for this
7669 any time soon. So, the current semantic for packet sending
7672 o If you send packet to remote host and do not force the send
7673 (the packet will be in queue) then all subsequent packets to the
7674 same remote host must also be put to the queue. Only after the
7675 queue has been purged is it safe again to force the packet
7678 o If you send all packets immediately then it safe to send
7679 any of subsequent packets through the queue, however, after
7680 the first packet is put to queue then any subsequent packets
7681 must also be put to the queue.
7683 Follow these rules and everything works fine.
7685 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7687 * Added new function silc_server_remove_clients_by_server to
7688 remove all client entries from ID list when the server connection
7689 is lost. In this case it is also important to invalidate all
7690 client entires as they hold the invalid server entry. This
7691 fixes fatal bug when server has lost connection and will reconnect
7694 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7696 * Made some sanity checks to silc_server_daemonise like to check
7697 whether the requested user and group actually exists.
7699 * Added sanity check to SKE's silc_ske_responder_finish to check
7700 that the public and private key actually is valid.
7702 * Invalidate the client's nickname when receiving Replace ID
7703 packet and the Client ID is being replaced. This means that the
7704 server will query the nickname if someone needs it (client)
7707 * Sort the ID Cache in client library when the ID Cache data
7708 has changed (needs sorting).
7710 * Do not allow for SILC client to create several connections to
7711 several servers. The client does not support windows right now
7712 and generating multiple connections causes weird behaviour.
7714 Irssi-silc client does support windows and can handle several
7715 connections without problems, see: www.irssi.org and SILC plugin.
7717 * Fixed some places where client was added to the IDList. The
7718 rule of thumb is following (in order to get everything right):
7719 If the client is directly connected local client then the
7720 `connection' argument must be set and `router' argument must be
7721 NULL to silc_idlist_add_client function. If the client is not
7722 directly connected client then the `router' argument must
7723 bet set and the `connection' argument must be NULL to the
7724 silc_idlist_add_client function.
7726 * The funtion silc_server_packet_send_local_channel actually did
7727 not check whether the client was locally connected or not. It
7728 does that now. Fixed a bug related to LEAVE command.
7730 * Fixed Remove Channel User payload parsing bug in server's
7731 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7733 * The server's silc_server_save_channel_key now checks also the
7734 global ID list for the channel as it might not be in the local
7735 list. Fixed a bug related to LEAVE command.
7737 * Is this the end of the [<unknown>] buglet that has been lurking
7738 around for a long time? A little for loop fix in server's
7739 silc_server_command_whois_parse that is used by both IDENTIFY
7740 and WHOIS command. At least, this was a clear bug and a cause
7741 of one type of [<unknown>] buglet.
7743 * WHOIS and IDENTIFY commands call the function
7744 silc_server_command_[whois/identify]_check function even if
7745 we are not router server.
7747 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7749 * Added --with-gmp configuration option. If set the GMP
7750 is always compiled in the SILC source tree. If not set then
7751 it is checked whether the system has the GMP3 installed. If
7752 it has then the GMP won't be compiled (the system's headers
7753 and library is used), if it doesn't have it then the GMP is
7754 compiled in the SILC source tree.
7756 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7758 * Changed RSA private exponent generation to what PKCS #1
7759 suggests. We try to find the smallest possible d by doing
7760 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7761 not security fix but optimization.
7763 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7765 * Added new config entry [Identity] to fork the server and run
7766 it as specific user and group. A patch from Bostik.
7768 * Imported Dotconf configuration library into lib/dotconf.
7769 This will be used to create the SILC configuration files later.
7770 It will appear in the distsribution after this commit.
7772 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7774 * A big code auditing weekend happening. Auditing code for
7775 obvious mistakes, bugs and errors. Also, removing any code
7778 Removed files for being obsolete:
7780 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7781 inline in the file lib/silcutil/silcbuffer.h)
7783 o lib/silcutil/silcbufutil.c (the header has inline versions)
7785 Changed code to fix possible error conditions:
7787 o The buffer formatting routines now check that the destination
7788 buffer really has enough space to add the data. This applies for
7789 both buffer formatting and unformatting
7790 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7791 unformatting was changed to accomodate following rules:
7792 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7793 sent to the function while XXX_*STRING will not allocate or copy
7794 the data into the buffer. Instead it sets the pointer from the
7795 buffer into the pointer sent as argument (XXX_*STRING used to
7796 require that the pointer must be allocated already). This change
7797 makes this whole thing a bit more consistent and more optimized
7798 (note that the data returned in the unformatting with XXX_*STRING
7799 must not be freed now). The routines return now -1 on error.
7801 o Tried to find all code that use buffer_format and buffer_unformat
7802 and added return value checking to prevent formatting and
7803 especially unformatting errors and possible subsequent fatal
7806 o Changed ske->x and ske->KEY to mallocated pointers in
7807 lib/silcske/silcske.h. Fixed possible data and memory leak.
7809 o Added return value checking to all *_parse* functions. Fixed
7810 many memory leaks as well.
7812 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7813 so that buffer overflows would not happen. All code now also
7814 checks the return value as it can fail.
7816 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7818 * Added reconnection support to server if the normal server looses
7819 its connection to the router (for example if router is rebooted).
7820 The server performs normal reconnection strategy implemented
7821 to the server. Affected file silcd/server.c.
7823 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7825 * Added new packet type SILC_PACKET_SET_MODE that is used to
7826 distribute the information about changed modes (for clients,
7827 channels and clients channel modes) to all routers in the
7828 network. Updated the protocol specification accordingly.
7830 Added functions into silcd/packet_send.c and
7831 silcd/packet_receive.c: silc_server_send_set_mode,
7832 silc_server_set_mode.
7834 Added new files silcmode.[ch] into lib/silccore that implements
7835 the encoding and decoding of Set Mode Payload. Added new type
7836 SilcSetModePayload. Moved the definitions of different modes
7837 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7839 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7841 * Oops, a little mistake in server's connection authentication
7842 protocol. The protocol is not ended with FAILURE but with
7843 SUCCESS if the authentication is Ok. :) Affected file is
7846 * Implemented NICK_CHANGE notify handling in server in the file
7847 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7848 the local clients on the channel. After the changing nickname
7849 in router environment snhould work and the [<unknown>] nickname
7850 should appear no more.
7852 The silc_server_replace_id function that receives the Replace ID
7853 payload now sends the NICK_CHANGE notify type also in the file
7854 silcd/packet_receive.c
7856 * Changed WHOIS and IDENTIFY command to support the maximum amount
7857 of arguments defined in protocol specs (3328 arguments). This
7858 fixed a bug that caused problems when there were more than three
7861 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7863 * Added extra parameter, command identifier, to the
7864 silc_client_send_command so that explicit command identifier
7867 Changed that ID list routines uses specific command identifier
7868 when sending WHOIS/IDENTIFY requests to the server so that they
7869 can be identified when the reply comes back.
7871 Affected files lib/silcclient/command.[ch],
7872 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7874 * Added `sender' argument to silc_server_packet_send_to_channel
7875 to indicaet the sender who originally sent the packet to us
7876 that we are now re-sending. Ignored if NULL. Affected file
7877 silcd/packet_send.[ch].
7879 * Added some server statistics support in silcd/server_internal.h
7880 SilcServerStatistics structure and around the server code. Also
7881 send some nice statistics information when client is connecting
7884 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7886 * Fixed channel ID decoding in server's JOIN command reply in
7887 silcd/command_reply.c
7889 * Fixed braodcasting of replace ID payload to not to send it if
7890 we are standalone server in silcd/packet_receive.c.
7892 * Fixed all channel message sending routines to not to send
7893 packets to clients that has router set, since they are routed
7894 separately in the same function earlier. Affects file
7895 silcd/packet_send.c and all channel packet sending functions.
7897 * In USERS reply, res_argv[i] are not allocated, the table
7898 is allocated. Thus changed that free the table, not its
7901 * In server's whois_check and identify_check if the client is
7902 locally connected do not send any WHOIS commands - they are not
7905 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7907 * Fixed some minor bugs in client when sending WHOIS command. The
7908 arguments was in wrong order.
7910 * Removed statis function add_to_channel from server in
7911 silcd/command.c that was previously used with the joining but
7914 * Tested USERS command in router environment successfully with two
7915 routers, two servers and two clients.
7917 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7919 * Reorganized the USERS command and command reply in client library
7920 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7921 When the command is given by user we register a pending command
7922 callback that will reprocess the command after the reply has been
7923 received from the server. When reprocessing the packet we then
7924 display the information. Thus, the USERS information is displayed
7925 now in the command callback instead of in the command reply
7926 callback. The processing of the command is same as previously
7927 when server has sent the command reply in the JOINing process.
7929 * Added to USERS command in silcd/command_reply.c to join the client,
7930 we didn't use to know about, to the channel after we've created
7931 a client entry for it. Also, for clienet we did know already still
7932 check whether it is on the channel or not and add it if not.
7934 * Removed silc_server_command_join_notify as the function and its
7937 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7939 * Changed the client's pending command handling to the same as the
7940 server's pending command handling. It is also now possible to
7941 execute command reply functions from other command reply
7942 function as the function callbacks for commands and command
7943 replies are one and same. The pending commands are not static
7944 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7945 in client connection context. Thus, pending commands are server
7946 connection specific as it is convenient.
7948 Changed the function silc_client_command_pending and
7949 silc_client_command_pending_del and added new function
7950 silc_client_command_pending_check. Removed the
7951 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7954 * Added cmd_ident, current command identifier, to the client
7955 connection context in lib/silcclient/client.h to keep track on
7956 command identifiers used in command sending. Client's command reply
7957 function handling now supports the mandatory command identifiers.
7959 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7960 funtions in client to fully support pending command callbacks.
7962 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7963 as one of the arguments to the application in the command reply
7966 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7967 before first releasing SILC but came back. Now it is removed again
7968 and should come back nomore. The FORWARDED flag was used only
7969 by the JOINing procedure by forwarding the command packet to router.
7970 Now, the JOINing procedure has been changed to more generic (due
7971 to various router environment issues) and FORWARDED is not needed
7972 anymore for anything. The protocol specification is yet to be
7975 Now, removed silc_server_packet_forward from server and the flag
7976 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7978 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7980 * Renamed NAMES command to USERS command. The NAMES was named that
7981 due to historical reasons. Now it is renamed. Also, rewrote
7982 parts of the USERS command. The nickname list is not sent anymore
7983 by the server. Only Client ID and mode lists are sent in the USERS
7984 command. Changed this also to the protocol specification.
7986 The client now resolves the names and stuff after it receives
7987 the USERS list from the server when joining to the channel.
7989 * WHOIS and IDENTIFY commands has been changed to support multiple
7990 Client ID's per command. One can now search for multiple users
7991 in the network by sending only one WHOIS or IDENTIFY command.
7992 Changed the code and the protocol specifications.
7994 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7995 uses silc_server_command_whois_parse to parse the request. */
7997 * If normal server, do not parse the WHOIS and IDENTIFY requests
7998 before sending it to the router. Saves some time.
8000 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8002 * Fixed JOIN command on client library. Wrong number of arguments
8003 used to crash the client.
8005 * Added silc_server_channel_has_global function to check whether
8006 channel has global users or not.
8008 * Added silc_server_channel_has_local function to check whether channel
8009 has locally connected clients on the channel.
8011 * The silc_server_remove_from_one_channel now checks whether the
8012 channel has global users or not after given client was removed from
8013 the channel. It also checks whether the channel has local clients
8014 on the channel anymore. If it does not have then the channel entry
8015 is removed as it is not needed anymore.
8017 * The silc_server_notify now checks on JOIN notify whether the joining
8018 client is one of locally connected or global. If it is global then
8019 the channel has now global users on the channel and that is marked
8020 to the channel entry. Also, it now saves the global client to
8021 global list who is joining and JOINs it to the channel. This is
8022 for normal server, that is.
8024 Changed silc_server_send_notify_on_channel,
8025 silc_server_packet_relay_to_channel and
8026 silc_server_packet_send_to_channel check if we are normal server
8027 and client has router set (ie. global client) do not send the
8028 message to that client, as it is already routed to our router.
8030 * Implemented LEAVE notify type handling in silc_server_notify
8033 * Tested LEAVE command in router environment successfully. Tested
8034 with two routers, two servers and two clients.
8038 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8040 * Implemented SIGNOFF notify type handling in silc_server_notify
8043 * silc_server_remove_id now removes the client entry from all channels
8044 it has joined and thusly sends SIGNOFF notify type.
8046 * Rewrote the NAMES list generation in server by removing two excess
8047 loops. The lists are created now inside one loop.
8049 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8051 * silc_server_remove_channel_user checks now also global list
8052 for channel and client.
8054 * silc_server_new_channel_user checks now both local and global
8055 list for channel and client. Fixed a bug in client id decoding.
8056 Used to decode wrong buffer.
8058 * silc_server_channel_message checks now both local and global
8059 list for channel entry.
8061 * Tested channel joining (hence JOIN) in router environment
8062 successfully. Tested with two routers, two servers and two
8065 * Tested channel message sending in router environment successfully.
8067 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8069 * Added silc_server_save_channel_key into server.[ch] to save the
8070 received channel key in Channel Key payload processing. It is
8071 also used in JOIN command reply handling.
8073 Equivalent function silc_client_save_channel_key added into
8074 client.[ch] into client library.
8076 * Changed JOIN command reply to send information whether the channel
8077 was created or not (is existing already) and the channel key
8078 payload. Changed protocol specs accordingly.
8080 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8081 the request was sent by ID and not by nickname. Crashed on
8084 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8086 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8087 now correctly save the received data.
8089 * silc_server_free_sock_user_data now notifies routers in the
8090 network about entities leaving the network.
8092 At the same time implemented functions silc_server_remove_id
8093 and silc_server_send_remove_id to receive and send REMOVE_ID
8094 packets. The packet is used to notify routers in the network
8095 about leaving entities. The ID removed will become invalid in
8098 * Added function silc_idlist_del_server into server. Removes and
8099 free's server entry from ID list.
8101 * silc_server_private_message function now checks, if we are router,
8102 that the destination ID really is valid ID, naturally.
8104 * In router when NEW_ID packet is received (for new client) the
8105 hash of the Client ID is saved in the ID Cache but the
8106 client->nickname is set to NULL, instead of putting the hash
8109 IDENTIFY command now also checks that client->nickname must be
8110 valid. If it is not if will request the data from the server who
8111 owns the client. Added new function
8112 silc_server_command_identify_check.
8114 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8115 to set the command to already allocated Command Payload.
8117 * Tested private message sending in router environment with two
8118 routers, two servers and two clients. Fixed minor bugs and now
8121 * Fixed segfault from client's NAMES command. Used to crash if
8124 * Forwarded packets must not be routed even if it is not destined
8125 to the receiver. Changed server code comply with this.
8127 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8129 * Added `require_reverse_mapping' boolean value to ServerParams
8130 structure. If TRUE (not default) the server will require that
8131 the connecting host has fully qualified domain name.
8133 If the reverse mapping is not required and hostname could not be
8134 found the IP address is used as hostname.
8136 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8138 * Implemented version string checking to both client and server.
8139 The check is incomplete currently due to the abnormal version
8140 strings used in development version of SILC.
8142 * Changed all command functions in server to use the new
8145 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8147 * Changed char *data to unsigned char *data in ID Cache system to
8148 support binary data as ID Cache data. Changed code to support
8149 binary data in lib/silccore/idcache.c.
8151 * Renamed silc_server_packet_relay_command_reply to
8152 silc_server_command_reply as it is normal packet receiving
8153 function. Rewrote the function to accept command replys for
8154 servers and not only for clients.
8156 * Mark remote router always as registered server if we are connecting
8157 to it. Otherwise, commands sent by the router to us are ignored.
8159 * All ID List find routines now returns the ID Cache Entry pointer
8160 as well if requested.
8162 * WHOIS command works now in router environment, tested with two
8163 routers, two servers and two clients.
8165 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8166 in router environment (as it is almost equivalent to WHOIS) but
8167 hasn't been tested thoroughly. Added new functions:
8169 silc_server_command_identify_parse
8170 silc_server_command_identify_send_reply
8171 silc_server_command_identify_from_client
8172 silc_server_command_identify_from_server
8174 * Disabled route cache adding because adding two different ID's with
8175 same IP replaces the old cache entry thus giving wrong route.
8176 The entry->router->connection is always the fastest route anyway
8177 so route cache may not be needed. Of course, new routes maybe
8178 established after receiving the ID when the entry->router->connection
8179 might not be anymore the most optimal.
8181 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8183 * Add route cache for received ID for fast routing.
8185 * Added silc_server_packet_route to route received packet on router
8186 that is not destined to us.
8188 * Renamed silc_server_get_route to silc_server_route_get.
8190 * Added id_string and id_string_len fields into SilcServer to
8191 include encoded ServerID for fast comparing without excess
8192 encoding of the ID's.
8194 * Cleaned up WHOIS command on server side. Added following static
8197 silc_server_command_whois_parse
8198 silc_server_command_whois_check
8199 silc_server_command_whois_send_reply
8200 silc_server_command_whois_from_client
8201 silc_server_command_whois_from_server
8203 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8204 arguments in command replies. All command functions should be
8205 updated to use this macro.
8207 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8209 * Minor typo fixes on command reply handling on server.
8211 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8213 * Added silc_server_command_add_to_channel internal routine to add
8214 the client to the channel after router has created the channel and
8215 sent command reply to the server.
8217 * Added generic silc_server_send_command to send any command from
8220 * Use static buffer with ID rendering instead of duplicating data.
8222 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8224 * Fixed a channel user mode bug when joining to a channel server gave
8225 everybody channel founder rights, oops.
8227 * We mark ourselves as the router of the incoming server connection
8228 if we are router ourselves. This way we can check in some packet
8229 sending functions whether it is locally connected server. For
8230 incoming router connections we put NULL.
8232 * For router sending packets locally means now always sending the
8233 packet cell wide; to local clients and local servers. For normal
8234 server sending packet locally means sending it to only local
8237 * Fixed the JOIN command to really work in router environment. If the
8238 channel is created it is always created by the router. Router is
8239 also responsible of making the initial joining to the channel,
8240 sending JOIN notify to the sending server and distributing
8241 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8242 does not exist server doesn't do anything else but forward the
8243 command to the router which performs everything.
8245 * Added silc_server_send_channel_key function to send the Channel Key
8248 * Added silc_server_create_channel_key to create new channel key. The
8249 channel key is now re-generated everytime someone joins or leaves
8250 a channel, as protocol dictates. Note: channel->key_len is the
8253 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8255 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8256 packet_receive.[ch] to separate packet sending and receiving
8257 routines. The server.[ch] now includes everything else including
8258 actual packet processing (writing and reading data) and other
8261 Renamed silc_server_private_message_send_internal to
8262 silc_server_send_private_message. The routine is still though
8263 used only to relay private messages as server does not send
8264 private messages itself.
8266 Renamed silc_server_new_channel to silc_server_create_new_channel
8267 and added new function sicl_server_new_channel that handles the
8268 incoming New Channel packet. Added also new sending function
8269 silc_server_send_new_channel to send New Channel Payload.
8271 * Added new function silc_server_notify to process incoming notify
8272 packet to the server/router. Server may then relay the notify
8273 to clients if needed.
8275 * Added new function silc_server_new_channel_user to process incoming
8276 New Channel User packet. Router will redistribute the packet and
8277 send JOIN notify to its local clients and locally connected servers
8278 if needed. Normal server will send JOIN notify to its local client
8279 on same channel when received this packet. Added also corresponding
8280 sending function silc_server_send_new_channel_user to sent the
8283 * Added boolean route argument to send_notif_to_channel and
8284 packet_send_to_channel functions to attempt to route the packet
8285 if it is TRUE and send only locally if it is FALSE.
8287 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8289 * silc_server_replace_id now broadcasts the received replace ID
8290 packet if it is not broadcast packet already. The router must
8291 broadcast to inform other routers about changed ID.
8293 * Added backpointer to server's router into SilcServer context in
8294 silcd/server_internal.h.
8296 * Fixed silc_server_packet_broadcast to send correct broadcast
8299 * The channel key is now distributed to the local client as soon
8300 as it is received from the router (in router environment) so that
8301 no other packet may be sent for the channel until client has
8304 * silc_server_remove_channel_user now broadcasts the received
8305 Remove Channel User packet if it is not broadcast packet already.
8306 The router must broadcast to inform other routers about removed
8309 * Added users field into SilcPacketContext that is a reference count
8310 of the context. One can increase the reference count by calling
8311 silc_packet_context_dup which is now changed to just increase the
8312 reference count instead of duplicating the data. The reference
8313 count is decresed by calling silc_packet_context_free that will
8314 free the data after the reference count hits zero.
8316 For now on the packet context and everything allocated into it
8317 (including the raw packet from network) must be freed by calling
8318 the new silc_packet_context_free function. Added also new function
8319 silc_packet_context_alloc that must be used now to allocate the
8320 context. This also means that if a routine is asynchronous from
8321 silc_[client/server]_packet_parse_type the packet context must
8322 be duplicated by calling silc_packet_context_dup. Otherwise it
8323 gets free'd after silc_[client/server]_packet_parse_type returns.
8324 Also, one must remember that if packet is duplicated then its
8325 reference count must be decresed by calling the free function as
8326 many times as it was duplicated.
8328 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8329 from both client and server.
8331 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8333 * Made joining to a channel working in router environment.
8335 * Cleaned up JOIN command on server side and create function
8336 silc_server_command_join_channel internal routine to make the
8339 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8341 * Changed silc_command_pending list to SilcDList. Also, added
8342 `ident' field to SilcServerCommandPending structure to identify
8343 the reply and to call correct callback.
8345 Added silc_server_command_pending_check function to replace the
8346 corresnponding macro. The silc_command_pending list is not
8349 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8350 to set identifier to previously allocated Command Payload. It
8351 is used to set identifier for command when resending Command
8354 * Added silc_command_payload_encode_payload to encode Command
8355 Payload buffer from SilcCommandPayload structure.
8357 * Added silc_argument_payload_encode_payload to encode Argument
8358 payload buffer from SilcArgumentPayload structure.
8360 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8362 * Changed WHOIS command to support router connection on server side.
8363 The whois request is always sent to router unless the server is
8364 standalone server. After server has received the reply from the
8365 router will it send the reply to the client.
8367 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8368 broadcast received broadcast packet. The function is used only
8369 by router. The broadcast packet is always sent to the router's
8372 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8373 render given ID to printable string, for log files for example.
8375 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8377 * Made basic router to router connections working. At least they
8378 can now connect to each other but nothing really works the way
8379 they are supposed - yet.
8381 * Added new initiator token to RouterConnection configuration
8382 file in silcd/serverconfig.[ch]. It is used to tell whether we
8383 are the initiator to the remote router or whether we'll expect
8384 the other end to connect.
8386 * Moved registering of listener task to silc_server_init, hence
8387 the server starts listenning as soon as it is run, even if it
8388 does not have connections to other routers. Let's see how well
8391 * Changed default connection retry timeouts for more suitable in
8394 * Removed cipher and such arguments from silc_idlist_add_client
8395 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8396 Added new function silc_idlist_add_data to add the keys and stuff
8399 * Added SilcIDListData structure and added it to SilcClientEntry
8400 and SilcServerEntry as their first field in the structure. This
8401 way we can explicitly cast the ID entries to the SilcIDListData
8402 structure and get common data for the entries. In past, we had
8403 to first check what type of connection it is and then cast it to
8404 correct ID entry type. Now, we can directly cast the opaque
8405 pointer to the SilcIDListData (no matter what ID entry it actually
8406 is) and get the data needed.
8408 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8410 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8411 in some circumstances even if threre were timeout tasks, though not
8412 IO tasks, but tasks anyway. Now fixed.
8414 * Defined SilcServerConnection structure to hold connection specific
8415 stuff about directly connected servers and routers. The definition
8416 is currently in silcd/server_internal.h. I thought about having
8417 a bit more important role fro this struct but for now it is used
8418 only when connecting to other server (or router actually).
8420 * Added connecting retry support in server when connecting to
8421 router(s). The retry feature implement exponential backoff
8422 algorithm. Also, added SilcServerParams structure to hold default
8423 parameters for server. For now, it include these retry settings
8424 and are hard coded. After server is moded to be as Silc Server
8425 Library this structure will be more important.
8427 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8429 * Changed client librarys channel->clients table to SilcList and
8430 changed code accordingly.
8432 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8434 * Changed client's channel table to SilcList and changed code
8435 accordingly. Also changed SilcChannelClientEntry to include back-
8436 pointer to the channel so that client entry can use that structure
8437 as list as well and we have fast cross-reference to the channel.
8438 This change dramatically decreased the complexity of channel
8439 handling with client entry and vice versa (removed one extra
8440 loop when searching for channel entry from many functions).
8442 * Changed server->sim from table to SilcDList and changed code
8445 * NAMES command can now be used from user interface. It will show
8446 the user list on the channel, neatly.
8448 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8449 Code now saves realname of the user if it becomes available.
8451 * Renamed configure.in to configure.in.pre and made ./prepare
8452 script to automatically add correct version string to
8453 configure.in which it creates from configure.in.pre.
8455 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8457 * NAMES command reply now shows users mode with the nickname when
8460 * Moved silc_client_ch[u]mode[_char] functions from
8461 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8462 place sucks, they are utility functions and should be in some
8465 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8467 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8470 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8474 * Added TRQ (efficient deque and list library) into lib/trq. This is
8475 a very good list library that is currently used in the SILC. Defined
8476 SilcList API over the library because I didn't like the API very
8477 much. See lib/trq/silclist.h for the API and examples of how to
8478 use the API. Fixed various places in the code to use the new
8479 SilcList API. The SilcList is meant for lists that has a structure
8480 already defined as a list. It is not suitable to add just some
8481 context to the list (in TRQ, the context is the list actually).
8483 So, I defined SilcDList that can be used for the purpose where
8484 predefined list structure does not exit. This can be used as
8485 such list. Now some context just can be added to the SilcDList.
8486 Currently this list is not used in the SILC just yet, though there
8487 are a lot places where this can replace dynamically allocated
8488 tables and I will fix these places, later, to use SilcDList.
8489 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8490 and use TRQ internally).
8492 Also fixed some annoying warning messages that the original TRQ
8493 code generated. Also minor changes to TRQ's Makefile.in.
8495 * Added support for querying by Client ID to both WHOIS and
8496 IDENTIFY commands into server, as required by the protocol.
8498 * Removed method function pointers from SilcBuffer structure. They
8499 weren't used to anything and just increased the context size for
8500 no good reason. This change also made silc_buffer_alloc and
8501 silc_buffer_free functions inline functions.
8503 * Disabled command flooding detection support until it's fixed so
8504 that it accepts commands in but does not execute them more than once
8507 * Added silc_net_localhost(), to return local hostname, into
8508 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8509 that must be initialized before calling silc_client_init.
8511 * Added new function: silc_server_send_notify_on_channels to send
8512 notify messages to all channels client has joined. It is assured
8513 that the message is sent only once per client.
8515 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8516 lib/silcutil/silcutil.[ch] as silc_format function. The new
8517 function is generic and is used by server as well, not only by
8518 the logging routines.
8520 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8521 the provided version string was not acceptable. Added new function:
8522 silc_ske_check_version into lib/silcske/silcske.h. The function
8523 must be implemented by the application (client or server) and it
8524 does not reside in the SKE library. The function checks the version
8525 string remote end sent.
8527 * Added back pointers (to opaque context and to SilcSocketConnection)
8528 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8530 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8531 duplicate packet context structure.
8533 * Changed `notify' client operation to send same arguments as client
8534 receives from server except for ID's. ID's are mapped to correct
8535 ID entry and that is returned. Also, if channel entry is not sent
8536 by server but the notify is for channel the channel entry is sent
8537 to application (otherwise application doesn't know that it is for
8538 channel (library gets it from packet's Destination ID)).
8540 * Added silc_client_remove_from_channels into client library to
8541 remove a client from all channels it has joined to. Used when
8542 received SIGNOFF notify from server. Added also new function
8543 silc_client_replace_from_channels to replace old ID entry with
8544 new ID entry on all channels. Used when received NICK_CHANGE
8547 * Fixed ID Cache list handling in silc_idlist_get_client in
8548 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8549 to get (or query) client by ID.
8551 * Updated TODO list.
8553 * Added connection authentication status message defined by the
8554 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8555 support for these into the code in client and server side.
8557 * Added generic function silc_client_send_command to send any command
8558 with variable argument list. Application should use this function
8559 to send commands if the command functions provided by the library
8560 does not suite for the application's user interface needs.
8562 * Added new `failure' client operation. Application is notified about
8563 received failure packet if client is executing a protocol. In this
8564 case the protocol's execution has failed.
8566 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8567 is required by the protocol.
8569 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8570 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8573 * Added status flag to SilcSKE object to indicate realtime status
8574 of the SKE protocol.
8576 * Application receives now exactly same command reply arguments as
8577 the library receives from server. However, if ID is received the
8578 corresponding ID entry is returned to the application (eg. Client
8579 ID is mapped to correct SilcClientEntry entry and that is returned).
8580 Changed command_reply client operation due to this change.
8582 * Changed all ID's in commands and in command replys as ID Payloads.
8583 Change affected both client and server side codes.
8585 All ID's sent in SILC network (with execption of ID's in SILC
8586 Packet header) are sent in ID Payload to support variable length
8589 * Server now notifies nick changes and notifies all clients on
8590 the channels about the new nickname (about the new Client ID,
8593 * Implemented CMODE command to change channel modes. Supports all
8594 channel modes defined by the protocol specs except ban and invite
8595 lists. (Also, private channel key mode is supported but support for
8596 setting private channel key in client is missing, thus, this mode
8597 has no effect on client side (except that server requires that the
8598 client uses private channel key and normal channel traffic does not
8601 Also, invite mode works per se, but INVITE command does not work
8602 yet correctly, so you can set channel as invite only channel but
8603 inviting clients to the channel does not work (it is yet to be
8604 thought what's the best way to do it).
8606 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8607 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8608 Implemented CUMODE command to change user's mode on the channel.
8609 Supports all modes defined by the protocol specs.
8611 * Added NAMES command reply to return users modes on the channel.
8613 * Removed unnecessary and slow ciphers from lib/silccrypt.
8615 * Set SO_KEEPALIVE option to connection sockets by default.
8617 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8619 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8620 redefined the Notify Payload into protocol specs.
8622 * Added silc_id_payload_parse_id to get ID directly from raw
8625 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8627 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8628 accept searching by Client ID as well.
8630 * Added support for LEAVE and SIGNOFF notify types in client library.
8632 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8633 to parse ID Payload from raw data.
8635 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8637 * Added flags parameter into silc_ske_assemble_security_properties
8638 function in lib/silcske/silcske.[ch].
8640 * Changed notify client operation to fit better for notify messages
8641 sent by server. The notify payload received from server is now
8642 passed to the application (after parsing it to SilcNotifyPayload).
8643 It is application's responsibility to retrieve the arguments
8644 from the payload and show the message the way it wants. The message
8645 sent by server is implementation specific.
8647 * Changed public keys to comply with the protocol specification.
8648 Old public keys are not supported anymore and are not compatible.
8650 * Removed nickname from Channel Payload as the latest draft removed
8651 it. The client must resolve the nickname from the NAMES command
8652 reply received when it joined the channel.
8654 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8656 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8658 * Fixed some errors in protocol specification drafts.
8660 * Created lib/silccore/silcnotify.c to implement Notify Payload
8661 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8662 generic payloads described by protocol specifications. The file
8663 includes implementations for ID Payload and Argument Payload.
8665 * Changed Command Payload implementation to use the new Argument
8666 Payload. Changed command_xxxx_payload to command_payload_xxxx
8667 to comply with SILC coding conventions.
8669 * Added suppport for Argument Payload handling in Notify Payload
8670 implementation as protocol requires it. Added the new support
8671 into server and client lib as well.
8673 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8675 * Added support for multiple nicknames on same channel. [n] is
8676 added locally to the nickname if there are more than one same
8677 nicknames on the channel.
8679 * Server now sends all nicknames that matched WHOIS request.
8680 Client also shows the list received from server.
8682 * Added TOPIC command to client side. User can now set and show
8683 current topic on channel.
8685 * Added MOTD command to client and server. Also, server sends the
8686 motd when client connects to the server.
8688 * Changed version strings to comply ISO 8601.
8690 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8692 * Fixed protocol error handling in client library. It should now
8693 cope even if the SKE fails for some reason.
8695 * Made new protocol specification drafts for submitting to IETF.
8697 * Implemented TOPIC command to server in silcd/command.c.
8699 * Added two new notify types into lib/silccore/silcnotify.h:
8700 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8701 notify nickname change and topic setting/change on a channel.
8703 * API change of command_reply operation in client library. The
8704 application gets now the status type received from server as well.
8706 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8708 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8710 * Cras fixed and optimized the packet handling even further and
8711 it should work now. Minor change to the prototype of function
8712 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8714 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8716 * Added new function into lib/silcutil/silcschedule.[ch]:
8717 silc_schedule_with_fd to select() a specified fd. The function
8718 returns after timeout expires or data arrives or goes. The
8719 function is used by packet routines to wait that all data is
8720 received from network.
8722 * Fixed data reading from network in lib/silccore/silcpacket.c.
8723 The code now assures that all data is read from the fd and then
8724 continues packet processing. This was a bug fix since the code
8725 used to drop some data in some circumstances.
8727 * Added new function into lib/silcclient/client.[ch]:
8728 silc_client_start_key_exchange to start key exchange after
8729 connection has been established to server. The code internally
8730 now uses this funtion but its main purpose was to provide it
8731 for applications that perform their own connecting. After
8732 application has created a connection it merely calls this
8733 function to start the key exchange between client and server.
8734 The library takes care of everything else after that.
8736 Updated also lib/silcclient/README to explain the usage of
8739 * Do not send to application information that connection has
8740 been established. Application gets notified it by connect
8743 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8745 * Applied cras's patch to add silc_schedule_one function. The
8746 function runs scheduler once and returns.
8748 * Fixed the scheduler after cras messed it up. The timeout
8749 handling works now as it's supposed to work.
8751 * Added into lib/silccore/ silcnotify.h to include notify
8752 message types support. Changed silc_server_send_notify*
8753 functions, in server.[ch], to support those new notify types.
8754 Added the support for the notify types into client library,
8755 as well. Added new notify client operation into ops.h in
8758 * Changed silc_server_packet_send_to_channel to send normal
8759 packets instead of just channel message packets. The function
8760 is now used to send the notify packets to channels. It is not
8761 used to send channel message packets anymore, as server never
8764 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8765 va_arg()s as it seems to require it nowadays. I guess, if SILC
8766 is compiled with older va_arg() the new code should work anyway.
8768 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8770 * Splitted core library. Core library (lib/silccore) includes
8771 now only SILC protocol specific core (and common) components.
8772 Created new utility library (lib/silcutil) that includes more
8773 generic purpose stuff. The stuff for util library was taken
8774 from the old core library. This was minor and easy split.
8776 * Created SILC Client Library (lib/silcclient) that includes
8777 implementation of the SILC client without user interface. This
8778 was major move from silc/ directory. The code has been changed
8779 so that it is transparent towards the user interface. The
8780 silc/ directory includes now the same user interface as before
8781 and it uses the new client library. Read lib/silcclient/README.
8782 Basicly, the client library performs everything else related
8783 to SILC except user interface handling. Also, configuration
8784 files are considered to be part of user interface and library
8785 does not handle them.
8787 This change also changed a lot of structures, function naming etc.
8788 Most important change was that SilcClientWindow object was
8789 renamed to SilcClientConnection in the client library. Created
8790 also new file lib/silcclient/ops.h. Also added new files
8791 silc/local_command.[ch] and silc/client_ops.[ch].
8793 All these changes were made to make it easier for user interface
8794 designers to create what ever user interface for the SILC client
8797 It is also expected that the server will be moved to lib
8798 directory as well and SILC Server Library will be created;
8799 sometimes in the future.
8801 * Removed Local commands from lib/silccore/silccommand.h as
8802 they are application specific and new client library does not
8803 handle any of those anymore.
8805 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8806 old client implementation in silc/.
8808 * Added support for callback functions in SILC_LOG_* macros.
8809 Application can now set its own callbacks that will be called
8810 instead of using the default functions that will always print
8811 the debug messages to stderr (or stdout). Also, debugging can
8812 now be disabled by setting silc_debug to FALSE and re-enabled by
8813 setting it to TRUE. Note, that logging will still work even
8814 if debugging is disabled.
8816 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8817 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8818 silc_log_reset_debug_callbacks.
8820 * To enable debugging in silc client one must give now -d
8821 option on command line.
8823 * Changed silc_schedule_init to automatically allocate task queues
8824 if they are not allocated before calling it.
8826 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8828 * Added GMP 3.1 into math library.
8830 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8832 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8833 a channel in SILC network. The packet is used by servers and
8834 routers to notify other routers that user has left a channel.
8835 This little feature was missing until now. Added the feature
8836 to protocol specification as well.
8838 Added functions: silc_server_send_remove_channel_user and
8839 silc_server_remove_channel_user into server.[ch].
8841 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8842 lib/silccore/silcpacket.h. However, they are not implemented
8845 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8847 * Fixed joining to a channel and sending channel messages
8848 between server and router. The channel message sending should
8849 now work inside a cell.
8851 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8853 * Fixed the private message sending between server and router.
8854 The private message sending should now work inside a cell.
8856 * Added silc_server_replace_id into server.[ch] to replace
8857 existing ID in the SILC network.
8859 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8860 and silc_idlist_replace_server_id into idlist.[ch] in server.
8862 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8864 * Fixed the server to server connections. Server can again now
8865 connect to router. Router to router connections probably does
8868 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8870 * Added dynamic protocol registering support. Now protocols can
8871 registered and unregistered on the fly. Patch by cras.
8873 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8875 * Added lib/contrib directory to hold routines that some platforms
8876 don't have but are needed by SILC.
8878 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8879 into lin/contrib to provide getopt() and getopt_long() for
8880 those who don't have it.
8882 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8884 * Added AWAY command to client. When away message is set and
8885 client receives a private message packet the client automatically
8886 replies to the sender with the away message.
8888 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8889 bug seemed to be the cause of recent problems when compiling
8892 * Added version detection support to SKE protocol specification
8893 and added the new changes to the SKE implementation as well.
8894 There were other minor changes in the SKE protocol as well.
8896 Many changes in lib/silcske/silcske.[ch] and in
8897 lib/silcske/payload.[ch].
8899 * Added ^U functionality, clear input line. Patch from cras.
8901 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8903 * Mainly small bugfixes on core library. Fixed some debugging
8904 logging and buffer overflow in silclog.c.
8906 * Updated config.sub and config.guess on the distribution tree.
8908 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8910 * Added command lagging support in server. Client may execute
8911 commands now only once in two seconds.
8913 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8915 * Optimized packet reception. MAC computation and checking is now
8916 also more optimized. A lot previously duplicated code is now
8917 used as generic by both client and server.
8919 * Fixed key pair generation in clientutil.c
8921 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8923 * Added into lib/silccore/silcbufutil.[ch] new function;
8924 silc_buffer_realloc.
8926 * Moved generic packet sending/encryption functions to
8927 lib/silccore/silcpacket.[ch] from client and server. Some
8928 rewriting of the functions.
8930 * Moved all generic packet reception/decryption functions to
8931 lib/silccore/silcpacket.[ch] from client and server. The
8932 packet processing is now much cleaner in both client and server.
8933 These were major changes in both client and server.
8935 * Created many common functions in server to do packet sending.
8936 Previously code were duplicated a lot, this has been removed
8939 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8941 * Rewrote major parts of the ID cache system. Don't know
8942 whether it is better now or not but at least the API is more
8945 * Major rewrite on ID cache stuff on client because of the ID
8946 cache API changes. Added idlist.c to client.
8948 * Also major rewrite on ID cache stuff on server as well.
8949 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8950 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8951 in hand, instead they are all put into the ID cache system now.
8952 All server_idlist_* routines uses ID cache now instead of
8953 traversing its own lists (those lists does not exist anymore).
8954 SilcIDList though still exists. Also, SilcXXXEntry's are
8957 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8959 * Finally made the SKE implementation compliant to the protocol
8960 specification. All mp integers are now binary encoded as
8961 opposed being HEX encoded.
8963 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8966 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8967 functions: silc_[encode/decode]_pem. Also added function
8968 silc_encode_pem_file to PEM encode with newlines ('\n') for
8971 * SILC public keys are now encoded either PEM or binary. Same
8972 option is for private keys as well. By default private keys
8973 are binary encoded and public keys PEM encoded. Silly HEX
8974 encoding were removed.
8976 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8977 function to create fingerprints.
8979 * Fixed a bug in SHA1; does not change the original data anymore.
8981 * Partly implemented INFO command on client and server side.
8982 Fixed CLEAR command. Changes to SERVER command; show current
8983 server(s) when giving command without arguments. Added
8984 VERSION command to client.
8986 * Added check to server that unregistered connections cannot
8987 execute commands (unless it is specificly allowed).
8989 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8991 * Fixed screen refresh.
8993 * Fixed channel joining bug from client. On some circumstances
8994 client tried to join to a channel it had already joined.
8996 * Added public key verification process into client's protocol.c.
8997 The client now verifies the public key from user and saves
8998 it into ~./silc/serverkeys/ directory.
9000 Added into: clientutil.[ch]: silc_client_verify_server_key.
9002 * Changed SKE protocol's silc_ske_initiator_finish function
9003 to accept callback function that verifies the received public
9004 key. Removed old silc_ske_verify_public_key function.
9006 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9008 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9009 silc_pkcs_private_key[_data]_set.
9011 * Made the password and public authentication more cleaner in
9012 server's protocol.c.
9014 * Removed historic and obsolete protocol `channel_auth' from
9015 both client and server.
9017 * Removed wrong way of sending command status messages from
9018 server to client in server's command.c. The old way violated
9019 protocol specification.
9021 Changes to silccore/silccommand.[ch]: removed
9022 silc_command_encode_status_payload -> not needed anymore,
9023 changed silc_command_encode_payload_va to accept extra
9024 argument on variable argument list. The argument type must
9025 now be provided to the function. Also, added new function:
9026 silc_command_encode_reply_payload_va which is same as
9027 normal command_encode_payload_va except command status type
9028 is provided as extra argument.
9030 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9032 * Added ~./silc directory handling. The directory includes the
9033 public and private keys for the client.
9035 Added silc_client_check_silc_dir, silc_client_create_identifier
9036 and silc_client_load_keys.
9038 * Implemented SILC protocol compliant public key. Added public
9039 and private key saving to and loading from files.
9041 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
