1 Sun Sep 8 13:13:44 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Distribute the SERVER_SIGNOFF notify also to local backup
4 routers from the primary router. The backup router may not
5 have the signing of local server directly connected and need
6 to know about the signoff. Affected file silcd/server_util.c.
8 * Use the primary router as the origin of the locally connected
9 server when it is disconnecting from the backup router since
10 that's where it really is coming from. Now the clients from
11 the disconnecting server are removed correctly and "shadow"
12 clients are not left to the backup router. Affected file
15 Sat Sep 7 22:26:50 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
17 * If normal server is standalone and found existing but disabled
18 channel, do not re-create the channel since it creates
19 duplicate same channels. Affected file silcd/server.c.
21 * Added anonymous client connections support to server. New
22 "anonymous" configuration option to ConnectionParams section
23 added. If set to true, the username and hostname information
24 of the client will be scrambled and anonymous user mode is
25 set automatically to the user. Affected files are
26 silcd/serverconfig.[ch], silcd/packet_receive.c and server.c.
28 Sat Sep 7 16:02:09 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
30 * In JOIN notify handling, mark that the cache entry of the
31 client cannot be expired. Can cause crashes on normal
32 server (asserts client->channels). Affected file is
33 silcd/packet_receive.c.
35 * From now on distribution versions are used as protocol versions
36 instead of by default using the Toolkit base version as protocol
37 version. Affected file prepare.
39 * Do not set the locally resolved hostname for local client
40 entry but take what server sends. This way the real hostname
41 is showed in WHOIS for yourself. Affected file is
42 lib/silcclient/idlist.c and lib/silcclient/client.c.
44 * Resolve local info with IDENTIFY when connecting to server.y
46 Sat Sep 7 14:22:43 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
48 * Rewritten check for POSIX threads. Use --with-pthreads[=DIR]
49 for implied search (not needed on platforms which has native
50 pthreads library). Use --without-pthreads to disable threads.
51 Affected file is configure.in.pre
53 * Fixed --with-iconv on platforms which need to bypass (broken)
54 native iconv(). Affected file is configure.in.pre
56 Sat Sep 7 15:08:13 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
58 * Moved -C option parsing in Irssi SILC client at same time
59 as other options. The UI was initialized earlier and caused
60 problems on command line. Bug #16. Affected file is
61 irssi/src/silc/core/silc-core.c.
63 Mon Sep 2 23:00:30 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
65 * Added global variable silc_log_timestamp that tells silclog
66 wether to print or not the timestamp in the logging files.
67 Affected file lib/silcutil/silclog.[ch].
69 * Added silcd configuration option Timestamp in the Logging
70 section. Affected file silcd/serverconfig.[ch],
71 doc/example_silcd.conf.in.
73 Fri Aug 30 08:57:33 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
75 * Fixed fingerprint checking to check for entirely empty
76 fingerprint instead of two first bytes when determining
77 if it is set. Bug #18. Affected file silcd/command.c.
79 * Fixed duplicate PKCS name registering to not allow it.
80 Bugs #17. Affected file lib/silccrypt/silcpkcs.c.
82 Sun Aug 25 08:02:04 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
84 * Conditionalize non-gcc compiler optimizations for various
85 platforms, enable those commented out. Cleanups.
86 Affected file lib/silcmath/mpi/configure.in
88 Sat Aug 24 15:11:32 EEST 2002 Timo Sirainen <tss@iki.fi>
90 * silc_rng_exec_command() left zombie processes if command
91 didn't generate any output. Affected file
92 lib/silccrypt/silcrng.c
94 Fri Aug 23 22:05:44 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
96 * Rewrote iconv checking, introduce --with-iconv for systems
97 which rely on libiconv. Check if iconv() provided by libc
98 is good enough, otherwise demand libiconv. Affected file
101 Fri Aug 23 07:10:52 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
103 * Search for ldopen() also in libc. This enables SIM support
104 on *BSD systems. Based on patch from Alex Zepeda. Affected
105 file configure.in.pre
107 Sun Aug 18 04:44:30 CEST 2002 Lubomir Sedlacik <salo@silcnet.org>
109 * Don't call AM_CONDITIONAL conditonally for SILC_THREADS.
110 This fixes prepare on *BSD systems. Affected file
113 Sun Aug 4 15:55:40 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
115 * More fixed for not having purge timeout for global clients
116 that are on channel. Affected files silcd/command_reply.c
119 * Fixed the rekey protocol to work with backup router connections.
120 Rekey packets are now allowed on disabled connections as
121 well. Affected files silcd/packet_send.c and server.c.
123 * Do not switch to be as backup router when shutting down and
124 closing the primary connection. Affected file silcd/server.c.
126 * Fixed memory leaks in backup router deleting. Added
127 silc_server_backup_free to free all data during shutdown of
128 server. Affected files silcd/server_backup.[ch].
130 Sun Jul 14 21:33:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
132 * Do not process commands if the sock->user_data is NULL.
133 Affected file silcd/command.c.
135 Tue Jul 9 19:03:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
137 * Fixed buffer overflow and security problems (loosing bits
138 in CFB encryption) in SILC RNG. Problems reported by
139 Markku-Juhani O. Saarinen <mjos@saturn.tcs.hut.fi>.
141 Sun Jul 7 13:10:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
143 * Added yet more checks that client is not expired on global
144 list if it is on channels. Affected file is
145 silcd/command_reply.c.
147 Sat Jul 6 11:45:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
149 * Merged c0ffee's MIME signal patch which adds support for
150 sending also MIME messages in Irssi SILC Client, and handling
151 received MIME messages in a signal (and perhaps doing something
152 to non-textual MIME messages).
154 Sun Jun 30 01:30:22 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
156 * Fixed pending command deletion in server and client library
157 to check the whole list instead of breaking after first found.
158 The affected files are silcd/command.[ch] and
159 lib/silcclient/command.[ch].
161 Sat Jun 29 17:40:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
163 * Return NO_SUCH_CHANNEL error in USERS for channel that is
164 secret or private, otherwise it's possible to find out
165 whether a secret channel exists or not. Affected file
168 * If CMODE change fails during the mode setting, assure that
169 the old mode mask is set for the channel back. Affected
170 file silcd/command.c.
172 * Fixed passphrase saving on +a channel on normal server
173 after successful JOIN command. Affected file silcd/command.c.
175 Fri Jun 28 11:53:25 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
177 * Remove server/router operator privileges in DETACH command,
178 since it's possible to resume to server where these
179 privileges would not be allowed for the client. Affected
180 file silcd/command.c.
182 * Do not set to wait for backup in rehash of the server.
183 Affected file silcd/server.c.
185 * Do not check listener sockets when counting how many
186 socket connections we have. Affected file is
189 * Do not announce disconnected clients that are remaining
190 in history (for WHOWAS). This is because SIGNOFF notify
191 for these has been sent earlier already. Affected file
194 Thu Jun 27 20:07:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
196 * Buffer overflow with CUMODE command's mode->mode character
197 conversion. Reported by Ville Räsänen. Affected file
198 lib/silcutil/silcutil.c.
200 Thu Jun 27 16:54:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
202 * Allow heartbeat packets to go disabled connections anyway.
203 Affected files silcd/server.c and silcd/packet_send.c.
205 * Do not broadcast New Channel packets with List flag set
206 in the packet to backup routers. The router must check
207 for the correctness of the packets before sending them.
208 It is possible that router will have enforce Channel ID
209 change and this would cause desync in the backup router.
210 Affected file silcd/packet_receive.c.
212 * Remove SILC_PACKET_FLAG_LIST from the temp packets that
213 are handled in list parsing. They are not list packets
214 anymore. Affected file silcd/packet_receive.c.
216 Thu Jun 27 11:27:07 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
218 * Stop waiting for backup router through the timeout, not
219 directly after backup router has arrived. Affected file
222 * Do not re-create channel keys and send them when removing
223 clients in server shutdown. Affected files are
224 silcd/server_internal.h and silcd/server_util.c.
226 * Notify distribution to backup routers was missing from
227 the silc_server_send_notify_dest function which caused
228 desyncing problems with backup router. Affected file is
231 * The client's channel removing was working wrong on
232 backup router. It assumed that it doesn't know global
233 information but backup router does know. For this reason
234 it could remove channel when it wasn't supposed to do that.
235 Affected file silcd/server.c and silcd/server_util.c.
237 Wed Jun 26 15:14:12 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
239 * Stop for a couple seconds after badkup router has become
240 primary router. Affected file silcd/server.c.
242 * Added silc_server_remove_servers_by_server, which is used
243 to remove servers originated from some other server. Also
244 clients of those servers can be removed too. Affected file
245 silcd/server_util.[ch].
247 * When removing clients after a server has signed of remove
248 also all servers behind that server (unless they are known
249 to be available locally), and send SERVER_SIGNOFF for each
250 of the server separately. Also the signed off clients are
251 sent now separately per signed off server. The affected files
252 are silcd/server.c and silcd/server_util.[ch].
254 * All servers added with silc_idlist_add_server must always
255 have both "router" and "connection" pointers set. Otherwise,
256 bad server entries may be left around in the cache.
257 Affected file silcd/command_reply.c.
259 * Do not create the channel key in NEW_CHANNEL packet
260 processing if the channel is empty. Affected file
261 silcd/packet_receive.c.
263 * Completed backup router support for standalone routers.
264 Supports also servers in the cell that do not use the backup
267 Wed Jun 26 10:38:11 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
269 * Fixed a bug in silc_string_regexify which did not add '^'
270 at the start of each string, and thus the matching was
271 not explicit. For example ban list iikone@*!*@* would
272 match also "priikone", which is wrong, it would have to be
273 *iikone@*!*@* to match also "priikone". Affected
274 file lib/silcutil/unix/silcunixutil.c.
276 Tue Jun 25 18:47:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
278 * Enable all local server connections before updating client
279 caches when we've become backup router. Otherwise, signoff
280 packets may not reach the clients. Affected files are
281 silcd/server.c and silcd/server_util.[ch].
283 * Fixed a bug in version string parsing which could crash
284 the program with specially formatted version string.
285 Bug reported and patch provided by Ville Räsänen. Affected
286 file lib/silcutil/silcutil.c.
288 * Handle the disconnection immediately when DISCONNECT
289 packet is received in server. Affected file silcd/server.c.
291 * Primary router now waits a short time (10 seconds) for
292 backup router connection before accepting any other
293 connection (except local). Affected file silcd/server.c,
296 * Fixed a crash in client libary in NICK_CHANGE notify when
297 NICK_CHANGE arrived for client entry we are resolving
298 currently. Affected file lib/silcclient/client_notify.c.
300 * Call the sconn->callback completion even if error had
301 occurred. Start reconnecting always if connection to
302 primary router fails during backup router protocol.
303 Affected files silcd/server.c and server_backup.c.
305 Mon Jun 24 17:47:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
307 * Added functions silc_server_send_opers and
308 silc_server_send_opers_notify to send packets stricly
309 to operators. Added macro SILC_SERVER_SEND_OPERS macro
310 to send variable argument notify to operators.
311 Affected files silcd/packet_send.[ch] and silcd/server.h.
313 * Removed UMODE rights checking with UMODE_CHANGE notify.
314 Affected file silcd/packet_receive.c.
316 * Server/router operator now receives notify when network
317 switches to backup router and when it resumes the use of
318 primary router. Affected file silcd/server.c and
319 silcd/server_backup.c.
321 * Fixed the updating of client information after backup
322 resuming protocol is over; update all except local clients
323 to the new primary router. The affected file is
326 * Added support for closing active connections in rehash
327 that were unconfigured by the user. Supports currently
328 closing server and router connections. Affected file
331 * Rewrote some SILC_LOG_DEBUG's in silcd/server_backup.c.
333 Sun Jun 23 17:32:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
335 * Don't do SILC_STRING_LANGUAGE encoding if the outbuffer
336 is NULL since seems that on some platforms NULL is allowed
337 and on some it's not. Fallback encoding is used instead.
338 Affected file lib/silcutil/silcstrutil.c.
340 * Fixed statistics updating for incoming server connection
341 which could cause problems when re-connecting. Affected
344 * Preliminary backup router support for standalone router
345 added. Affected files in silcd/.
347 * Mark server connections in backup router disabled before
348 and after backup protocol. Affected file is
349 silcd/server_backup.c.
351 * Added support for reconnecting to remote server connection
352 even if the protocol fails, and if the configuration wants
353 us to keep trying to connect anyway.
355 Server connection is not allowed to backup router if
356 backup router does not have connection to primary router yet.
358 Affected file is silcd/server.c.
360 Sat Jun 22 21:34:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
362 * Added silc_client_udpate_server function to update changed
363 server info. Affected file lib/silcclient/idlist.[ch].
365 * Added check for server entries that are being resolved when
366 notify is received. If being resolved, handle the received
367 notify only after it's resolved so that all notifys are
368 handled in same order as received from the server.
370 Added similar resolver check to channel entries. Every
371 notify that cause resolving of any information that affects
372 channel entry marks the channel entry in waiting state.
373 After whatever resolving is over the waiters are signalled
374 and only then the notifys are handled in the same order
375 as delivered from the server.
377 Affected files are lib/silcclient/idlist.[ch], and
380 * Fixed KILLED notify handling in normal server. Affected
381 file silcd/packet_receive.c.
383 * Added SILC_IDLIST_STATUS_LOCAL which indicates that entry
384 is locally connected, or was locally connected (but may
385 be detached and connection is not active). Added also
386 SILC_IS_LOCAL for checking this status. Affected files
387 silcd/idlist.h, silcd/packet_receive.c, silcd/server_util.c,
388 silcd/server.c and silcd/server_internal.h.
390 Sat Jun 22 17:06:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
392 * Don't send or handle TOPIC_SET if topic is already set and
393 is same as being set. Affected files silcd/command.c and
394 silcd/packet_receive.c.
396 * Fixed CMODE change rights checking to work correctly when
397 removing modes by operator. Affected file is
400 * Fixed some handling with New Channel packet in router and
401 fixed some CMODE_CHANGE notify handling in server and router.
402 Affected file is silcd/packet_receive.c.
404 * Changed "disconnect" client operation to include the
405 reason of the disconnection and optional disconnection
406 message. Affected file lib/silcclient/silcclient.h.
408 * Made the compilation of lib/contrib/ stuff conditional.
409 Affected files configure.in.pre, lib/contrib/Makefile.am.
411 Sat Jun 22 12:49:21 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
413 * All CMODE_CHANGE and CUMODE_CHANGE notifys are now sent back
414 to the sender of the notify too, to avoid situation where two
415 notifys are in the network at the same time going to oppsite
416 directions. Affected file silcd/packet_receice.c.
418 Fri Jun 21 10:00:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
420 * Delete the client from channel even if the cilent->id is
421 NULL. It was possible that client was deleted without
422 removing from channels (theoretically at least). Affected
423 file silcd/server.c and silcd/server_util.c.
425 * Free the client data too when resuming is not successful.
426 Affected file silcd/packet_receive.c.
428 * Merged some code from c0ffee's silc-plugin. Affected files
429 irssi/src/silc/core/silc-channels.c and silc-expandos.c.
431 * Added SILC_PRIMARY_ROUTE and SILC_BROADXAST macros to
432 silcd/server_internal.h. SILC_PRIMARY_ROUTE Returns pointer
433 to the primary router connection, the other one returns
434 TRUE if packet must be broadcasted to network.
436 * All notifys that are destined to primary router (to network)
437 are now automatically sent to backup routers even if the
438 router is standalone (and has backup router). Affected files
441 * Added --without-irssi and --without-silcd configuration
442 options for disabling the compilation of these applications.
443 Affected file configure.in.pre and prepare.
445 Thu Jun 20 13:48:15 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
447 * Implemented SILC_STRING_BMP and SILC_STRING_UNIVERSAL for
448 UTF-8 encoding and decoding. Added also new encodings
449 SILC_STRING_BMP_LSB and SILC_STRING_UNIVERSAL_LSB.
451 Added also SILC_STRING_LANGUAGE which is language and charset
452 specific encoder and decoer for those platforms that support
453 iconv(). It can convert the UTF-8 to and from the locale
454 specific character set.
456 Affected file lib/silcutil/silcstrutil.[ch].
458 * Added macro SILC_NOT_IMPLEMENTED to lib/silcutil/silclog.h.
460 * Added function silc_get_command_name to the file
461 lib/silcutil/silcutil.[ch].
463 * Improved the server debug output a bit. Affected files are
466 Wed Jun 19 17:46:31 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
468 * Save the channel passphrase when received succesful JOIN
469 command reply from router, on normal server. Otherwise
470 joinig +a channels from normal server is not possible.
471 Affected file silcd/command.c.
473 * Fixed a bug in TOPIC_SET notify handling. The notifier
474 may be other than client too, like server or channel.
475 It expected it to always be only client and ignored the
476 notify. Affected file silcd/packet_recieve.c.
478 * Removed some (unnecessary) debug printing from
479 lib/silccore/silcid.c and lib/silccore/silcargument.c.
481 * Do not force CMODE_CHANGE when server is announcing new
484 Router announces stuff only after server reannounces channel
485 after CHANNEL_CHANGE notify.
487 These fixes optimizes the announcing procedure, and perhaps
488 fixes some problems too. Affected file silcd/packet_receive.c.
490 * Fixed SERVER_SIGNOFF sending to local clients. It was
491 totally broken and sent the notify to all local clients,
492 instead of only to those that was on same channel as the
493 signing off clients. Affected file silcd/server_util.c.
495 * Added -D option to server. It can be used to give debug
496 level. The levels are from 0 - 99, and are predefined for
497 smooth server debugging. (see silcd.c for the predefined
498 levels). Affected file silcd/server.c.
500 Wed Jun 19 16:01:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
502 * Fixed a bug in Irssi SILC client to close the connection
503 properly when disconnecting from server. Affected file
504 irssi/src/silc/core/client_ops.c.
506 Tue Jun 18 17:14:52 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
508 * When authenticating as founder during JOIN command, check
509 that the one authenticating becomes the only founder on the
510 channel. Affected file silcd/command.c.
512 * Better checking for founder mode setting when CUMODE_CHANGE
513 notify is received. Affected file silcd/packet_receive.c.
515 * Close all connections when shutting down the server by sending
516 DISCONNECT packet. Close all listeners too when shutting
517 down the server. Affected file silcd/server.c.
519 * Handle DISCONNECT packet correctly in client library by
520 calling the "disconnect" client operation. Affected file
521 lib/silcclient/client.c.
523 * Handle local errors correctly during resuming. Affected
524 file lib/silcclient/client.c.
526 Tue Jun 18 10:26:27 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
528 * The log file is not dupped internally anymore in
529 lib/silcutil/silclog.c. Fixed memory leaks too.
531 * The scheduler now dispatches all pending timeout tasks
532 when it is uninitialized with silc_schedule_uninit.
533 Affected file lib/silcutil/silcschedule.c.
535 Mon Jun 17 21:30:55 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
537 * Added --enable-stack-trace option to configure. Added
538 memory allocation stack trace support. Added files
539 lib/silcutil/stacktrace.[ch]. Affected files are
540 lib/silcutil/silcmemory.[ch].
542 * Fixed memory leaks from libraries and server. Affected
543 files around the tree.
545 * Reverted back a fix made to CUMODE which broke it.
546 Affected file silcd/command.c.
548 Sun Jun 16 11:49:45 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
550 * Added SILC_MESSAGE_FLAG_UTF8 to the protocol specs and the
551 core library, and implemented it. All textual messages SHOULD
552 use this flag and the message MUST be UTF-8 encoded.
553 All text messages sent by Irssi SILC client are now UTF-8
554 encoded (regardless whether the terminal supports UTF-8 or not).
555 Affected files are lib/silccore/silcchannel.h,
556 irssi/src/silc/core/silc-servers.c, silc-channels.c and
559 Sat Jun 15 18:23:39 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
561 * Added lots of new statistics updating that was missing from
562 the server and router code. Affected files in silcd/.
564 * Sending SIGUSR1 signal to server now dumps the current
565 server statistics into /tmp directory. Affected file is
568 * ROBODoc documented the lib/silccrypt/silchash.h. Improved
569 the SILC Hash Interface also. Added new functions
570 silc_hash_get_name, silc_hash_init, silc_hash_update and
571 silc_hash_final. Affected file lib/silccrypt/silchash.c.
573 Sat Jun 15 12:09:14 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

1093 * Added new channel user mode BLOCK_MESSAGES which the client
1094 may set to itself to tell server not send channel messages.
1095 Other packets such as channel key packets are still sent.
1096 Protocol TODO #23. Updated the protocol specs, client and
1097 server. Affected files are lib/silccore/silcmode.h,
1098 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
1099 lib/silcutil/silcutil.c, silcd/command.c, and
1100 silcd/packet_send.c.
1102 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1104 * Redefined the Status Payload to include now two 8 bit fields,
1105 instead of one 16 bit field. This now makes it possible to
1106 send list of errors. Updated the protocol specs and the code
1107 in core library, client library and server. Protocol TODO #1.
1108 Affected files are lib/silccore/silccommand.[ch],
1109 lib/silcclient/command_reply.[ch], silcd/command.c,
1110 silcd/command_reply.c and silcd/packet_receive.[ch].
1112 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1114 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
1115 must be handled by the application and should tell the application
1116 that an error message was already printed, and it should print the
1117 config coords (line, filename, ...). Affected files are
1118 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
1120 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
1121 server config parsing code more readable.
1123 Fixed a bug in the fetch_logging() config callback.
1125 Affected files is silcd/serverconfig.c.
1127 * Drop root privileges when started in foreground. Don't drop them
1128 if debugging also. Affected file is silcd/silcd.c.
1130 Mon Apr 8 17:00:41 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1132 * Added more IM-like features by introducing new user modes
1133 for setting various presence information. Added new modes:
1134 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
1135 specs and code. Protocol TODO #19. Affected files are
1136 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
1137 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
1139 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1141 * Added STATS command to the protocol after all, to return
1142 various statistical information about the network. It can
1143 be used by clients to retrieve statistical information, and
1144 servers may use it to to fetch cell and network wide
1145 statistics from router. Updated the protocol specs and
1146 implemented it to the server. Protocol TODO #16.
1147 Affected files are lib/silccore/silccommand, silcd/command.[ch],
1148 silcd/command_reply.[ch].
1150 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1152 * The LIST command reply in client libary now adds new channel
1153 entry if the returned channel doesn't exist yet in cache,
1154 and returns the channel entry to the application in the
1155 command_reply client operation. Affected file is
1156 lib/silcclient/command_reply.c.
1158 * Changed the channel message payload's MAC generation to
1159 include the IV in the MAC as well. This way all relevant
1160 parts of the channel message payload are authenticated also
1161 with the channel message MAC (and not only by packet MAC).
1162 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1163 Affected file is lib/silccore/silcchannel.c.
1165 * Fixed the SKE to save the remote version, since the
1166 silc_ske_parse_version mistakenly checked wrong version,
1167 after it replaced the start payload. Affected files are
1168 lib/silcske/silcske.[ch].
1170 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1172 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
1173 string utility functions. Added there also new functions
1174 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
1175 Affected files lib/silcutil/silcstrutil.[ch].
1177 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
1178 files are lib/silcutil/silcstrutil.[ch].
1180 * Defined that the security property fields in SKE SHOULD be
1181 UTF-8 encoded, defined that version string MUST be US-ASCII
1182 encoded, defined that passphrases sent in connection
1183 authentication protocol MUST be UTF-8 encoded. Implemented
1184 these to the client and server. Defined also that other
1185 passphrases sent in the protocol MUST be UTF-8 encoded.
1186 Affected files are lib/silcske/silcske.c,
1187 lib/silcclient/protocol.c, silcd/protocol.c,
1188 silcd/serverconfig.c, and lib/silccore/silcauth.c.
1190 * Changed the silc_client_close_connection interface to not
1191 need the SilcSocketConnection which should not be visible
1192 to application. Affected files are lib/silcclient/client.c
1193 and lib/silcclient/silcclient.h.
1195 * Rewrote the text for Private Message Key Payload in the
1196 protocol specification. Protocol TODO #11.
1198 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1200 * Upgraded the protocol version to 1.1, updated protocol specs
1203 * Added the nickname as new argument to NICK_CHANGE notify and
1204 added it to protocol specs and implemented it to client and
1205 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
1206 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
1207 lib/silcclient/client_notify.c.
1209 * Added the killer's client ID to the KILLED notify and added
1210 it to protocol specs and implemented it to client and server.
1211 Protocol TODO #13. Affected files are silcd/command.c,
1212 silcd/packet_receive.c, packet_send.[ch],
1213 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1214 The killer's client entry is now returned to application in
1215 the `notify' client operation.
1217 * Fixed the Max Argument fields that had too large value set
1218 in the protocol specs. Protocol TODO #14.
1220 * Added the LEAVE command reply to return the ID of parted
1221 channel. Updated protocol specs and implemented it to the
1222 client and server. Protocol TODO #15. Affected files are
1223 silcd/command.c, lib/silcclient/command_reply.c. The channel
1224 entry is now returned to application in the `command_reply'
1227 * Rewrote the version SKE version checking in client libary
1228 and in server to use the silc_parse_version_string. Affected
1229 files are lib/silcclient/protocol.c, silcd/protocol.c.
1231 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
1232 commands that was missing it, and updated protocol specs and
1233 the server implementation. Protocol TODO #10. The affected
1234 file is silcd/command.c.
1236 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1237 generic reply to a generic request (REQUEST flag), and
1238 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1239 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1240 to define the payload for DATA flag. Added the flags to
1241 the implementation. Protocol TODO #9. Affected file is
1242 lib/silccore/silcchannel.h.
1244 Changed the client library to return the message length
1245 to application as well in the channel_message and private_message
1246 client operations. Affected files are
1247 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
1248 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
1249 and lib/silcclient/client_ops_example.c.
1251 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
1252 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
1253 the channel. Updated protocol specs and impelemented this
1254 to client and server. Protocol TODO #6. Affected files are
1255 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
1256 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
1258 Added new options m and M to CMODE command in Irssi SILC
1259 client to set these modes.
1261 * Deprecated all administrative commands from SILC protocol
1262 since they are highly implementation specific commands.
1263 Updated protocol specs. Moved the old commands in
1264 implementations to private range of command types. Affected
1265 files are silcd/command.c, lib/silcclient/command.c and
1266 lib/silcclient/command_reply.c. Protocol TODO #8.
1268 * Fixed a bug in server where sending unknown command crashes
1269 the server. Affected file silcd/command.c.
1271 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1273 * Added SILC_PROTOCOLVERSION macro to check protocol version
1274 of a socket connection. The affected file is
1275 lib/silcutil/silcsockconn.h.
1277 * Added better error logging in rekey protocol. Affected file
1280 * Do not check public key types in SKE during rekey. Affected
1281 file lib/silcske/payload.c.
1283 * Fixed the rekey protocol with PFS, which was totally broken.
1284 Affected file silcd/protocol.c.
1286 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1288 * Some client implementations quit network by doing first LEAVE
1289 and then immediately SIGNOFF (like Bombyx). We now do check
1290 after a short time after LEAVE notify and check whether the
1291 client is still valid after LEAVE, and if not we remove it from
1292 cache. Affected file is lib/silcclient/client_notify.c.
1294 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1296 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1297 it's good not to have security holes here.
1299 * Fixed a negative refcount situtuation for the config context.
1300 Affected file is silcd/serverconfig.c.
1302 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1304 * ROBOdoc documented lib/silcutil/silcutil.h.
1306 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1308 * Optimized even more the SilcPacketContext structure. Now
1309 totally saved 16 bytes of memory per context after optimization.
1310 Affected files are lib/silccore/silcpacket.[ch].
1312 * Made strict checks for valid SILC IDs. Affected file is
1313 lib/silccore/silcid.c.
1315 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1317 * Changed the object argument for silc_cipher_register,
1318 silc_hash_register, silc_hmac_register and silc_pkcs_register
1319 to const. Affected files are lib/silccrypt/silccipher.[ch],
1320 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1322 * Changed the silc_get_username and silc_get_real_name to
1323 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1325 * Fixed the Irssi SILC Client to use the silc_get_username and
1326 silc_get_real_name insted of glib routines since the glib
1327 routines only corrupt stack. Fixes the Irssi SILC to work in
1328 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1330 * Fixed the Irssi to not use g_get_home_dir since it crashes
1331 or returns garbage on cygwin and corrupts stack. Added function
1332 get_home_dir to Irssi routines. Affected files are
1333 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1335 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1337 * Made some structure optimizations. SFTP memory FS MemFSEntry
1338 entry structure. Optimized SilcTask structure. Optimized
1339 SilcPacketContext structure.
1341 Affected files lib/silcsftp/sftp_fs_memory.c,
1342 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1344 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1346 * And yet again reverted back the config thing since Johnny
1347 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1350 * Fixed memory leaks from config object. Affected files are
1351 silcd/serverconfig.[ch].
1353 * Added support for adding new connections to the server in rehash.
1354 After rehash they take effect.
1356 Added support for changing the maximum allowed connections in
1357 rehash. The number can grow but going smaller is not supported.
1359 Added function silc_server_num_sockets_by_remote to the
1360 silcd/server_util.[ch].
1362 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1364 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1366 * Added preliminary checking during config parsing for a valid
1367 public/private key and removed further checks in the code.
1368 Affected files are silcd/serverconfig.[ch], server.c.
1370 * Moved functions silc_server_drop() and silc_server_daemonise()
1371 from server.c to silcd.c since they are stricly related to
1372 the application activity.
1374 * Reverted a small part of the automatic ref/unref since
1375 it caused a double unref in some situations. Affected
1376 files are silcd/silcd.[ch], server.c, serverconfig.c.
1378 * Added some .cvsignore files in the lib directory.
1380 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1382 * Fixed silc_net_gethostbyaddr to correctly resolve by
1383 address. Affected file lib/silcutil/silcnet.c.
1385 * Fixed the notify relaying to client. The HMAC to be used
1386 with relayed packets ws wrong and caused decryption failure
1387 at the client end. Affected file is silcd/packet_receive.c.
1389 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1391 * Created new branch silc_protocol_1_0_branch.
1393 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1395 * Changed the silc_server_config_* routines to be SilcServer
1396 independent. They are now officially application specific code
1397 and not part of generic server implementation. Affected files
1398 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1400 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1402 * Added automatic referencing of config context in the
1403 silc_server_config_alloc, and automatic unreferencing in the
1404 silc_server_config_destroy. Affected files are
1405 silcd/serverconfig.[ch], silcd/silcd.c.
1407 * Fixed the silc_log_quick handling in the logging routines.
1408 It didn't log quickly when it was TRUE. Affected file is
1409 lib/silcutil/silclog.c. Also the flush delay was set even
1410 if it was 0 in config file. Affected file is
1411 silcd/serverconfig.c.
1413 * Added support for changing key pair of the server in rehash.
1414 Affected file silcd/server.c.
1416 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1418 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1419 too early, before getting the channel entry. Affected file
1420 is silcd/packet_receive.c.
1422 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1424 * Added functions silc_server_config_[ref/unref], these are used
1425 to prevent that the config object is destroyed.
1427 No longer directly affect global variables silc_log_quick and
1428 silc_log_delay, they are first cached inside the config object
1429 and then applied with silc_server_config_setlogfiles().
1431 silc_server_config_set_defaults() is now internal to
1432 serverconfig.c, there are no reasons to show this internal stuff
1435 Affected files are silcd/serverconfig.[ch].
1437 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1438 fprintf's to stderr, since some code may be executed again after
1439 the server went into the background. Affected files are
1442 * Added rehash support. Added function silc_server_rehash() that
1443 will perform all the basic tasks of the rehashing procedure.
1445 * Added command line option `-x, --hexdump'. This will enable the
1446 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1447 The option `--hexdump' implies `--debug'.
1449 * Fixed a bad bug in the logging APIs (silcutil library) where
1450 the application would crash after calling silc_log_reset_all().
1452 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1454 * Fixed the KICKED notify handling in client library to
1455 correctly remove the channel and all entries from the
1456 channel when I was kicked. This bug crashed the client.
1458 Fixed yet another but in KICKED notify handling to remove
1459 the kicked client correctly from the channel.
1461 Affected file is lib/silcclient/client_notify.c.
1463 * Fixed a minor bug in looking up correct client entry
1464 in KICKED notify in server. Affected file is
1465 silcd/packet_receive.c.
1467 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1468 sources correctly to distribution. Fixes --with-gmp option.
1470 * Removed the manual rehashing from ID Cache, and changed it
1471 to use the SILC Hash Table's auto rehash feature. Affected
1472 file is lib/silccore/silcidcache.c.
1474 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1476 * Fixed a bug in the silc_client_nickname_format function that
1477 handles the multiple same nickname formatting. Two clients
1478 with same nickname caused problems after the first one left
1479 and rejoined. It didn't format the nickname correctly.
1480 Affected file is lib/silcclient/idlist.c.
1482 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1484 * Don't change the topic if olod topic is same as new one.
1485 Affected file is silcd/packet_receive.c.
1487 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1489 * Added cross-reference support to the SILC Documentation
1490 generator. All types across all HTML files are now cross-
1491 referenced. Affected files util/robodoc/generator.c and
1492 scripts/silcdoc/silcdoc.
1494 * Added file lib/silcutil/silctypes.h to include all the
1495 arithmetic type definitions and some macros. Removed
1496 includes/bitmove.h and moved macros to silctypes.h.
1498 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1500 * Merged bugfixes for Irssi SILC client from irssi.org CVS.

1504 * Added `type' argument to silc_id_payload_parse_id function which
1505 now returns the type of the ID to the sent pointer. Affected
1506 file is lib/silccore/silcid.[ch].
1508 * Added check for CMODE_CHANGE notify type that mode change is
1509 allowed by the sender. Affected file silcd/packet_receive.c.
1511 * Added check for CUMODE_CHANGE notify type that mode change is
1512 allowed by the sender. Affected file silcd/packet_receive.c.
1513 Added the ID type as CUMODE_CHANGE notify type as argument
1514 to the `notify' client operation. Affected files are
1515 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1517 * Added function silc_client_add_server to the client library.
1518 Added support for resolving also channel and server info when
1519 received unknown entity in notify packet. Affected files are
1520 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1522 * Added function silc_command_get_status to return the command
1523 status from the command reply's argument payload. Affected files
1524 are lib/silccore/silccommand.[ch].
1526 * Added check for KICKED notify type that the kicking is
1527 allowed by the client. Affected file silcd/packet_receive.c.
1529 * Created function silc_get_input which can be used to get input
1530 (echo on or off) from user on command line. Affected files are
1531 lib/silcutil/silcutil.[ch].
1533 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1535 * Optimized silc_server_packet_relay_to_channel function.
1536 Added new function silc_channel_message_payload_encrypt which
1537 can be called directly if channel message payload needs to
1538 be encrypted and is already encoded (no need to call _encode
1539 function). Packet relaying is now done by router without any
1540 extra memory allocations. Affected files are
1541 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1542 silcd/packet_send.c.

1554 * Changed the silc_server_client_on_channel to return the
1555 SilcChannelClientEntry as well. Moved the function
1556 silc_server_check_cmode_rights to server_util.[ch].
1557 Affected files are silcd/server_util.[ch], silcd/command.c.
1559 * Added function silc_server_check_umode_rights to check whether

1562 by the client. Affected files are silcd/server_util.[ch],
1563 silcd/packet_receive.c and silcd/command.c.
1565 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1567 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1568 ID length. It ignored that ID can be IPv6 based as well.
1569 Affected file lib/silccore/silcpacket.h.
1571 * Fixed the silc_id_id2str and silc_id_str2id to take the
1572 IPv6 address offset's into consideration. Affecte file is

1583 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1584 can specify different directory with --home command line
1585 parameter. Affected files irssi/src/silc/core/client_ops.c,
1588 * SILC-specific commands aren't now executed if the active server
1589 isn't of SILC-type, so there won't be problems with having
1590 IRC and SILC protocol support in same client. Affected files
1591 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1594 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1596 * Improved the signal support in SILC Schedule. Added new
1597 function silc_schedule_signal_call which is used by application
1598 to mark a signal to be called. It is now safe to perform
1599 any kind of tasks in signal callbacks since it is guaranteed
1600 that the application specified signal callback is called
1601 after the signal is over. Affected files are
1602 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1604 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1606 * Added `name' field to SilcChannelPrivateKey to represent
1607 application given name for the key. Moved also the context from
1608 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1609 Added the `name' argument also to the function
1610 silc_client_add_channel_private_key.
1612 Added function silc_client_current_channel_private_key to set the
1613 current channel private key in use.
1615 Added "change" command to KEY command which can be used to change
1616 the current channel private key. Bound the command also to
1617 alt+K (Alt+Shift+k).
1619 Also affected files lib/silcclient/client_channel.c,
1620 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1622 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1624 * Added silc_rng_get_byte_fast function in to the
1625 lib/silccrypt/silcrng.[ch].
1627 * Changed the interface of silc_packet_assemble and the
1628 silc_packet_send_prepare. If silc_packet_assmble is now
1629 called the application does not call silc_packet_send_prepare
1630 because the library will call it automatically. These
1631 interfaces now also return a reference to the outgoing buffer
1632 which includes the assembled packet, which the application can
1633 use to encrypt the packet.
1635 Affected files are lib/silccore/silcpacket.[ch],
1636 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1637 silcd/packet_send.c, server_backup.c and packet_receive.c.
1639 * Fixed a packet sending bug on very high load, where outgoing
1640 packet queue wasn't handled correctly and packets got corrupted.
1641 Affected files are lib/silcutil/*/silc*sockconn.c,
1642 lib/silcclient/client.c and silcd/server.c.
1644 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1646 * Added macro SILC_PACKET_DATALEN which can be used during
1647 packet assembling to check whether the data to be added to
1648 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1649 len is truncated until it fits it.
1651 Added checks for maximum length of channel message payload and
1652 private message payload also.
1654 Added checks for maximum packet length in server and in
1657 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1658 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1659 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1660 lib/silcclient/client_prvmsg.c.
1662 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1664 * Added silc_server_packet_queue_purge call to the
1665 silc_server_disconnect_remote to assure that all data in the
1666 queue before disconnecting is sent to the network. Affected
1667 file silcd/server.c.
1669 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1671 * Added the deleting of server's own ID cache entry to the
1672 silc_server_free function. Free also everything else that
1673 has been allocated in silc_server_init. The affected file
1676 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1678 * Added functions silc_parse_version_string, silc_version_to_num,
1679 and silc_ske_parse_version to parse SILC protocol style version
1680 strings. Affected files lib/silcutil/silcutil.[ch] and
1681 lib/silcske/silcske.[ch].
1683 * Added new configuration params: version_protocol, version_software
1684 and version_software_vendor to specify what version the remote
1685 host must at least be to be able to connect to server. The vendor
1686 string can be regex matched too. Added new function
1687 silc_server_connection_allowed to check maximum number of allowed
1688 connections, and allowed versions for incoming connections.
1689 Affected files are silcd/server.c, server_util.[ch] and
1692 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1694 * Added preliminary support for signals in scheduler. The
1695 signals we care about are now blocked always when the scheduler
1696 is locked. This way we can synchronise the use of signal with
1697 scheduler. It is guaranteed that when signal occurs the scheduler
1698 is not locked, and thus new tasks can be safely added to the
1701 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1702 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1703 Added new platform specific routines
1704 silc_schedule_internal_signals_[un]block and
1705 silc_schedule_internal_signal_[un]register.
1707 Added new functions to SILC Schedule API:
1708 silc_schedule_signal_[un]register. Each signal that application
1709 is going to use should be registered to the scheduler.
1711 Affected files are lib/silcutil/silcschedule.[ch],
1712 lib/silcutil/*/silc*schedule.c.
1714 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1716 * Check for unauthenticated client and server in the
1717 silc_server_new_client and silc_server_new_server functions.
1718 Affected file silcd/packet_receive.c.
1720 * Added function silc_string_is_ascii to check whether given
1721 string is 7-bit ASCII string. Affected files are
1722 lib/silcutil/silcutil.[ch].
1724 * Added function silc_id_is_valid_server_id into the
1725 silcd/serverid.c and added checking for valid Server ID's in
1726 silc_server_new_server. The Server ID must always be based
1727 on the server's public IP address.
1729 * Added logging of DISCONNECT packet message in the server.
1730 Affected file silcd/server.c.
1732 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1734 * Changed all library interfaces that use Global RNG to also
1735 accept SilcRng as argument. Affected files are
1736 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1737 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1738 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1739 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1740 lib/silccrypt/rsa.c.
1742 * Added function silc_pkcs_generate_key to the
1743 lib/silccrypt/silcpkcs.[ch] for applications so that they
1744 don't need to do pkcs->pkcs->init calls anymore.
1746 * Remove SilcSocketConnection from the SFTP API since it really
1747 wasn't needed there. The application has the information
1748 saved in its contexts anyway and the SFTP layer doesn't need
1749 know about it. Affected files lib/silcsft/silcsftp.h and
1750 lib/silcsftp/sftp_[server/client].c.
1752 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1753 The SilcSimContext is not SilcSim.
1755 * Fixed possible buffer overflows in silc_id_render in the
1756 lib/silcutil/silcutil.c.
1758 * On EPOC the global crypto module lists are not used at all
1759 in the crypto library. Added support for using the constant
1760 algorithm list on EPOC. Affected files are
1761 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1764 * Fixed the handling of third parameter of KICKED notify, since
1765 it was mistakenly updated to SILC Protocol 1.0 even though it
1766 is to be included in 1.1. Since it is not in 1.0 it is not
1767 mandatory, and this fix now handles it only if it is provided,
1768 and it is not error if it is not provided. Affected file
1769 lib/silcclient/client_notify.c.
1771 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1773 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1774 client. Affected file irssi/src/silc/core/client_ops.c.
1776 * Merged with Irssi 0.8.4 from irssi.org CVS.
1778 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1780 * Check for valid socket connection in client entries before
1781 sending any messages. Fixes a crash, but doesn't fix some
1782 other underlaying bug that is lurking there. Affected
1783 file silcd/packet_send.c.
1785 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1787 * $usermode, $cumode and $cumode_space expandos shouldn't do
1788 anything with non-SILC server records. Affected file
1789 irssi/src/silc/core/silc-expandos.c
1791 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1793 * Fixed the silc_net_check_[host/local]_by_sock to support
1794 IPv6 bound sockets as well. Now they can return IPv6 addresses
1795 as well. Affected file lib/silcutil/silcnet.c.
1797 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1798 Affected lib/silcutil/unix/silcunixnet.c.
1800 * Fixed ID rendering (at least on some platforms, not NetBSD)
1801 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1803 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1805 * Added silc_hash_public_key and silc_hash_public_key_compare
1806 functions to be used with SilcHashTable. They can be used to
1807 hash public keys and compare public keys in hash table. Affected
1808 file lib/silcutil/silcutil.[ch].
1810 * Added support for specifying multiple public keys for Client
1811 connection section in server configuration file. This makes it
1812 possible to accept multiple public keys from same host, or to
1813 make a section that accepts any incoming host, and have the
1814 accepted public keys listed in the section.
1816 Added functions silc_sever_[find/get]_public_key, added the
1817 support for this actually to all connection sections but only
1818 the Client section is currently allowed to specify multiple
1821 Affected files are silcd/server.c, server_internal.h,
1822 command.c, protocol.c, server_util.[ch], packet_receive.c.
1824 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1826 * Merged Irssi 0.8.2 from irssi.org CVS.
1828 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1830 * If silc_debug is TRUE, also output standard logging messages
1831 to stderr with the debug output.
1833 Made silc_log_reset_all() flushing all channels before returning.
1834 Also fixed some documentation typos.
1836 Affected files are lib/silcutil/silclog.[ch].
1838 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1840 * Fixed the server to check correctly the amount of connections
1841 from single host, by checking also the type of the connection.
1842 Fixed also the comparison of number of connections and number
1843 of allowed connections. Affected files are silcd/server.c,
1846 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1848 * Fixed the USERS command reply to save the user's mode on the
1849 channel as well. Fixed JOIN command reply to check whether a
1850 client is on channel already and not join it twice. Affected
1851 file lib/silcclient/command_reply.c.
1853 * Added new file silc-expandos.c into irssi/silc/core/ to return
1854 various stuff for various signal for the statusbar etc. updating.
1855 Now Irssi SILC client prints channel user modes etc. on the
1858 * The user mode (like server/router operator changes) is now shown
1859 on the Irssi SILC client's statusbar. The affected files are
1860 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1862 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1864 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1865 to SILC_SCHEDULE_[UN]LOCK macros.
1867 * Added more error printing to logs in server code. Affected
1868 files silcd/server.c and silcd/protocol.c.
1870 * Fixed -S option parsing in Irssi SILC Client. Affected file
1871 irssi/src/silc/core/silc-core.c.
1873 * Added silc_buffer_alloc_size function. Affected file is
1874 lib/silcutil/silcbuffer.h.
1876 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1878 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1879 constants. Affected files in
1880 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1883 * Changed the internal SFTP Memory FS table to const. Affected
1884 file lib/silcsftp/sftp_fs_memory.c.
1886 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1888 * Fixed the buffer formatting and unformatting routines to
1889 check the size of 64 bits types with sizeof(). Affected
1890 file is lib/silcutil/silcbuffmt.c.
1892 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1894 * Removed 0.6.x backwards support.
1896 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1898 * Changed all integer type names:
1899 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1900 to avoid collisions with other libraries using same type names
1903 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1905 * Added `prefer_ipv6' argument to the functions
1906 silc_net_gethostbyname[_async]. If it is TRUE it will return
1907 IPv6 address over IPv4. If FALSE IPv4 address is returned
1908 even if IPv6 address was found. Affected files
1909 lib/silcutil/silcnet.[ch].
1911 * Added support silc_net_create_connection[_async] to fallback
1912 to IPv4 address if IPv6 address could not be used (like if
1913 it doesn't work on a specific system). Affected file in
1914 lib/silcutil/unix/silcunixnet.c.
1916 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1919 of the max tasks handling capabilities of the scheduler.
1920 Affected files lib/silcutil/silcschedule.[ch].
1922 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1924 * Added automatic extern "C" { ... } for C++ compilers so the
1925 application does not need to define them. Affected file
1926 includes/silcincludes.h.
1928 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1929 old name went against naming convention. Applications now
1930 include "silcclient.h" instead of "clientlibincludes.h".
1931 Removed includes/clientlibincludes.h, it is redundant now.
1933 * Renamed includes/version.h to silcversion.h.
1935 * Added really preliminary support for OS/2 into the util
1936 library. Only thread & mutex API is implemented, others
1937 are still to be implemented. Created the lib/silcutil/os2/
1938 directory. Created also file includes/silcos2.h.
1940 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1942 * Added preliminary BeOS support into the util library.
1943 Created lib/silcutil/beos/, and implemented all the needed
1944 functions to support SILC on BeOS. Created also file
1945 includes/silcbeos.h.
1947 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1949 * Added proper initializations to silc's irssi code, so it's
1950 now possible to load it as module. Affected files
1951 irssi/src/silc/core/silc-core.c,
1952 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1954 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1956 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1959 * Fixed the silcdoc document generator to correct generate
1960 docs from all kinds of filenames. Affected files are
1961 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1963 * ROBOdoc documented lib/silcutil/silcmemory.h.
1964 Added also new function silc_memdup.
1966 * Removed lib/silcutil/silcbufutil.h and moved those routines
1967 to the lib/silcutil/silcbuffer.h.
1969 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1971 * Added `user_count' to the SilcChannelEntry which now tells the
1972 number of users on the channel. The user count is now saved
1973 in normal server of global channels as well. Affected files
1974 silcd/server.c, idlist.h, packet_receive.c and command.c.
1976 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1977 include file utility functions.
1979 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1980 instead of calling directly OS routines.
1982 * Fixed NICK change printing in Irssi SILC Client. Fixed
1983 KICKED notify printing in Irssi SILC Client. Affected file
1984 irssi/src/silc/core/client_ops.c.
1986 * Fixed a NICK change bug in client library, to not recreate the
1987 client_entry->channels hash table everytime nick is changed.
1988 Affected file lib/silcclient/client.c.
1990 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1992 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1993 the SKE interface a bit.
1995 * Fixed padding problem in PKCS#1. The padding was not actually
1996 random since the random number generator was used incorrectly.
1997 This security bug affects only when encrypting with PKCS#1, and
1998 it is not currently used at all in SILC. SILC only use signing
1999 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
2001 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2003 * Rewrote the notify handling in Irssi SILC client to not call
2004 the events as signals. Fixes problems with Perl support.
2005 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
2007 * Send the auto-nicking NICK command in client library with
2008 little timeout after connecting. The affected file is
2009 lib/silcclient/client.c.
2011 * Added following new config file settings:
2012 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
2013 key_exchange_timeout, conn_auth_timeout, connections_max,
2016 Implemented all the new config settings handling in the server.
2018 Optimized the use of SKE Mutual flag usage. Use it only
2019 if connection authentication protocol is not based in public
2022 Renamed all SilcServerConfigSection* to SilcServerConfig*
2023 to have a bit shorter names.
2025 Affected files silcd/serverconfig.[ch], server.[ch], and
2028 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2030 * Cleaned up the listening sockets code, preparing for the rehash
2031 support. Affected file is silcd/server.c.
2033 * Fixed some output messages. Affected files are silcd/silcd.c,
2036 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2038 * Create lib/doc/silcrng_intro.html document as introduction
2039 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
2041 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2043 * Fixes to the silcd config template. Affected file is
2044 doc/example_silcd.conf.in.
2046 * Removed type casts from silc_calloc(), conforming to the
2047 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
2049 * Removed param_name member from client, server, and router
2050 section structs, now identifying the param directly.
2052 Added CONFIG_FREE_AUTH macro in config file parsing.
2054 Affected files are silcd/serverconfig.[ch].
2056 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
2058 * Fixed command line parameter handling. All SILC initialization
2059 is now done in silc_core_init() which also fixes autoconnecting
2062 Affected files irssi/src/silc/core/silc-core.c,
2063 irssi/src/fe-text/silc.c.
2065 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2067 * Added new configuration options and blocks:
2068 keepalive_secs, reconnect_count, reconnect_interval,
2069 reconnect_interval_max, reconnect_keep_trying and
2070 require_reverser_lookup. Added ConnectionParam block, and
2071 implemented the connection parameters when connecting as
2072 initiator and when accepting connections as responder.
2074 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
2075 whether given configuration value has been given already.
2077 Affected files silcd/serverconfig.[c], server.[c].
2079 * Splitted the doc/example_silcd.conf.in. Separated the crypto
2080 algorithm parts and created new file silcalgs.conf, that
2081 is now included from the example_silcd.conf.in.
2083 * Optimized the silc_server_connect_to_router_second to take
2084 the connection configuration object from the SilcServerConnection
2085 object instead of finding it during the connecting phase.
2086 Added the configuration object to SilcServerConnection struct.
2087 Affected files silcd/server_internal.h, server.c.
2089 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2091 * Add the client on channel after it was resolved at the
2092 channel message receiving, and it was not already on the
2093 channel. Affected file lib/silcclient/client_channel.c.
2095 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2097 * Fixed the public key authentication to allocate always the
2098 destination signature buffer instead of using static buffer.
2099 Affected file silcd/protocol.c.
2101 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2103 * Unified the serverconfig.[ch]'s helper function interface.
2104 Affected file silcd/serverconfig.[ch].
2106 * Removed doc/example_silc.conf.in since it is redundant.
2107 The make install will now install irssi/silc.conf file.
2109 * Added new Passphrase and Publickey authentication methods to
2110 config file, allowing both public key and passphrase based
2111 authentication to be set at the same time.
2113 Added `prefer_passphrase_auth' setting in config file which
2114 can be used to set to prefer passwd auth if both passwd and
2115 public key is set. If not set, public key is preferred.
2116 This has effect only when being initiator (responder will try
2119 Added support for authentication with passphrase and public key
2120 at the same time. The passphrase is tried first always since
2121 it is faster to check.
2123 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2125 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2127 * Merged the new SILC Config library, with the server parsing
2128 support. Read the header file silcconfig.h or the toolkit
2129 documentation for the news. Affected files are
2130 doc/example_silcd.conf.in lib/silcutil/silcconfig.[ch]
2131 silcd/command.c silcd/packet_receive.c silcd/packet_send.c

2135 * Fixed some silclog documentation. Affected file is
2136 lib/silcutil/silclog.h.
2138 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2140 * The silc_cipher_register, silc_hash_register and
2141 silc_hmac_register now checks if the object to be registered
2142 is registered already. Affected files are
2143 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
2145 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2147 * Merged new irssi from irssi.org's CVS, the version 0.7.99.

2151 * Allow zero length channel messages inside the Channel Message
2152 Payload. Affected file lib/silccore/silcchannel.c.
2154 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
2155 as header filenames.
2157 * Removed lib/silcclient/README and created HTML file
2158 lib/silcclient/silcclient_using.html, which is now included
2159 as part of Toolkit documentation.
2161 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2163 * Fixed CUMODE_CHANGE notify handling to change the mode of
2164 correct client. Affected file lib/silcclient/client_notify.c.
2166 * Make silc_rng_alloc fail if it cannot allocate the sha1
2167 hash algorithm. Affected file lib/silccrypt/silcrng.c.
2169 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2171 * Fixed the file transfer's key agreement payload to include
2172 zero port also if the hostname is NULL because it could not
2175 Call file transfer monitor callback now also if error occurs
2176 during key agreement protocol.
2178 Changed the silc_client_file_send interface to return the
2179 SilcClientFileError instead of session id. The session ID
2180 is returned into pointer provided as argument.
2182 Check that the file exists locally before sending the
2183 file transfer request at all.
2185 Affected file lib/silcclient/client_ftp.c, silcapi.h.
2187 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
2188 error than can occur while key agreement protocol. Affected
2189 file lib/silcclient/silcapi.h.
2191 * Fixed the event_mode CMODE handler to not crash when mode
2192 is changed and +k mode is set in the channel. Affected file
2193 irssi/src/silc/core/silc-channels.c.
2195 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2196 SILC_LOG_WARNING to give out Warning and not Error. Affected
2197 file lib/silcutil/silclog.c.
2199 * Fixed the channel message payload decryption in the function
2200 silc_channel_message_payload_decrypt to not modify the original
2201 buffer before it is verified that the message decrypted
2202 correctly. Otherwise, next time it is called with correct
2203 channel key it won't encrypt since the payload is corrupted.
2204 Affected file lib/silccore/silcchannel.c.
2206 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2208 * Do not constantly resize the window. A fix patch by cras.
2209 Affected file irssi/src/fe-text/screen.c.
2211 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2213 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
2214 Affected file lib/silcutil/silcnet.c.
2216 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2218 * Fixed a bug in hash table internal routine for traversing
2219 the table with foreach callback. The current entry may
2220 become invalid in the callback but it was referenced after
2221 the callback returned.
2223 Do not allow auto rehashing of hash table during the
2224 silc_hash_table_foreach operation, for same reasons as it is
2225 not allowed for SilcHashTableList. Affected files are
2226 lib/silcutil/silchashtable.[ch].
2228 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2230 * Defined DLLAPI into silcincludes.h and silcwin32.h for
2231 Win32 DLL. extern's in header files are now declared with
2234 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2236 * Fixed private message handling. It used some old code that
2237 caused the client to crash. Affecte file is
2238 lib/silcclient/client_prvmsg.c.
2240 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2242 * Added function silc_client_add_channel,
2243 silc_client_replace_channel_id, and removed functions
2244 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2245 from client library.
2247 * Added cross reference of the joined channels to the
2248 SilcClientEntry, and changed the SilcChannelEntry's
2249 users list to SilcHashTable. The affected files are
2250 lib/silcclient/idlist.[ch].
2252 * Fixed a bug in hash table tarversing. While the hash table
2253 is traversed with SilcHashTableList the table must not be
2254 rehashed. It is now guaranteed that auto rehashable tables
2255 are not rehashed while tarversing the list. Also defined that
2256 silc_hash_table_rehash must not be called while tarversing
2257 the table. Added function silc_hash_table_list_reset that must
2258 be called after the tarversing is over. The affected files are
2259 lib/silcutil/silchashtable.[ch].
2261 * Changed all hash table traversing to call the new
2262 silc_hash_table_list_reset in server and in client library.
2264 * Added function silc_client_on_channel to return the
2265 SilcChannelUser entry if the specified client entry is joined
2266 on the specified channel. This is exported to application as
2267 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2269 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2271 * Fixed founder regaining problem with JOIN command on normal
2272 server. The notify for mode change must be sent always and
2273 not only if !cmd->pending. Affected file silcd/command.c.
2275 * Fixed the WHOWAS command's reply sending to support the
2276 lists correctly. Affected file silcd/command.c.
2278 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2280 * When sending JOIN command to router for processing the
2281 sender's old command identifier was not saved back to the
2282 sender's command context, fixed now. The affected file is
2285 * Create the key in JOIN command of the router did not return
2286 the channel key, added check for this. Affected file is
2289 * Fixed a channel ID update bug in JOIN command reply. Do
2290 not directly upgrade the ID but call the function
2291 silc_idlist_replace_channel_id if the ID was changed.
2292 Affected file silcd/command_reply.c.
2294 * Fixed memory leaks from command calling if it would fail.
2295 Affected file silcd/command.c.
2297 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2299 * Applied patches from cras:
2301 Memory leak fixes around libaries, irssi window resize fix,
2302 new silclist.h and silcdlist.h, all extern inline changed to
2305 * Removed dotconf from lib/dotconf, not needed anymore.
2307 * Removed TRQ from lib/trq, not needed anymore.
2309 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2310 with server connections. Later this will be configurable
2311 in config file after new config file is done. Affected file
2314 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2316 * Fixed a crash in server related to channel announcements.
2317 Affected file silcd/server.c.
2319 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2321 * Fixed memory leaks in silc_server_create_new_channel*
2322 functions. Affected file silcd/server.c.
2324 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2325 which ID was changed. This way the router will send the
2326 user list for the channel again, and server won't be in
2327 desync in some rare circumstances. Affected file is
2328 silcd/packet_receive.c.
2330 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2332 * Check for NULL socket pointer in the function
2333 silc_server_packet_send_to_channel_real. Affected file
2334 silcd/packet_send.c.
2336 * Fixed the BAN notify handling to correctly remove ban
2337 list. Affected file silcd/packet_receive.c.
2339 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2341 * Fixed some header addition to Toolkit distribution in
2342 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2344 * Added lib/silcclient/client_ops_example.h as an template
2345 file for application programmers to quickly start using
2346 the SilcClientOperation functions in their application.
2347 Updated the lib/silcclient/README as well to tell about this
2348 nice file made available.
2350 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2352 * Call silc_server_remove_from_channels when removing client
2353 entry when NO_SUCH_CLIENT_ID was received. Affected file
2354 is silcd/command_reply.c.
2356 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2358 * Added server & router operator statistics updating. Affected
2359 file silcd/packet_receive.c and silcd/command.c.
2361 * Fixed the SERVER_SIGNOFF notify handling on normal server
2362 not to save the history information for clients. Same was
2363 fixed earlier in remove_clients_by_server function, but not
2364 here. Affected file silcd/packet_receive.c.
2366 * Raised the default connection-retry count from 4 to 7 in
2367 server. Affected file silcd/server.h.
2369 * Cancel any possible reconnect timeouts when we start the
2370 key exchange. Affected file silcd/server.c.
2372 * Do not reconnect on connection failure when SCONNECT was
2373 given. Affected files silcd/server.[ch].
2375 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2377 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2379 * Fixed the NICK command to always give the unformatted
2380 nickname to the one giving the NICK command. If unformatted
2381 nickname is cached already it will be formatted and the
2382 local entry will always get the unformatted nickname.
2383 Affected file lib/silcclient/idlist.c.
2385 * Fixed some double frees from client library commands.
2386 Affected file is lib/silcclient/command.c.
2388 * Fixed CUMODE command in server to assure that no one can
2389 change founder's mode than the founder itself, there was a
2390 little bug. Affected file silcd/command.c.
2392 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2394 * Removed the SilcClientCommandDestructor from the client
2395 libary, it is not needed anymore. Affected files are
2396 lib/silcclient/silcapi.h, command[_reply].[ch],
2397 client_notify, idlist.c.
2399 * Fixed GETKEY command to first resolve client, and then
2400 resolve the server only if the client was not found, instead
2401 of resolving both at the same time. Affected file is
2402 lib/silcclient/command.c.
2404 * Added silc_client_start_key_exchange_cb and lookup the
2405 remote hostname and IP address before starting the key
2406 exchange with server. The affected file is
2407 lib/silcclient/client.c.
2409 * The server's public key is now saved using the IP address
2410 of the server and not the servername for the filename.
2411 The hostname public key filename is checked as an fall back
2412 method if the IP address based filename is not found.
2414 Fixed the GETKEY command to save the fetched server key
2415 in correct filename.
2417 Print the remote server's hostname now when new key is
2418 received during connection process. Affected file is
2419 irssi/src/silc/core/client_ops.c.
2421 * Return always our own public key to the client if it asks
2422 for it with GETKEY command. Affected file silcd/command.c.
2424 * Removed the use_auto_addr variable from default config
2425 file since it was in wrong section. Affected file is
2428 * Fixed TOPIC_CHANGE notification to not route it when it
2429 was sent using silc_server_send_notify_to_channel function.
2430 Affected file silcd/command.c.
2432 * Fixed silc_server_send_notify_kicked to send the kicker's
2433 Client ID also, it was missing. Affected files are
2434 silcd/command.c, silcd/packet_send.[ch].
2436 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2438 * Do not save client history information in SERVER_SIGNOFF.
2439 Fixes the bug in normal server that it does not detect
2440 the client becoming valid after the server becomes back
2441 online. Affected file silcd/server_util.c.
2443 * Added `sock_error' field into the SilcSocketConnection
2444 context. When error occurs during socket operation (read
2445 or write) the error is saved. Added also new function
2446 silc_socket_get_error to return human readable socket error
2447 message. Affected files are lib/silcutil/silcsockconn.[ch],
2448 lib/silcutil/unix/silcunixsockconn.c, and
2449 lib/silcutil/win32/silcwin32sockconn.c.
2451 * The server now prints the socket error message in the
2452 signoff for client. Affected file silcd/server.c.
2454 * Fixed the `created' channel information sending from router
2455 to server in JOIN command. Checks now whether the channel
2456 really was created or not and set it according that.
2458 Fixed the JOIN command to use the client entry's current
2459 ID during the joining procedure instead of the one it sent
2460 in the command (it is checked though), since it can change
2461 between the packet processing and command processing, and
2462 would just case unnecessary pain in the client end. Affected
2463 file silcd/command.c.
2465 * Fixed a channel key payload sending to use correct channel
2466 ID when the server was forced to change the channel's ID by
2467 router. Router sent the key payload with the old Channel ID.
2468 Affected file silcd/packet_receive.c.
2470 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2472 * Call silc_server_save_channel_key only if the key payload
2473 was provided in the JOIN command's command reply. Affected
2474 file silcd/command_reply.c.
2476 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2478 * Fixed silc_mp_sizeinbase to return the value correctly with
2479 MPI. Affected file lib/silcmath/mp_mpi.c.
2481 * Fixed the stop_server signal to correctly stop the scheduler
2482 and gracefully stop the server when SIGTERM or SIGINT signals
2483 are received. Affected file silcd/silcd.c.
2485 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2487 * Simple handling of TERM and HUP signals. Also added some log
2488 flushing call around. Affected file is
2491 * Fixed small bugs in silclog.c. Now buffering output will take
2492 effect after 10 seconds since startup: This will ensure that
2493 no important startup messages are lost. Also output redirection
2494 will preserve original format ([Date] [Type] message).
2495 Affected file is lib/silcutil/silclog.c.
2497 * Added two options to the config file, in the logging section:
2498 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2499 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2501 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2503 * Do not print the warning about log files not being initialized
2504 more than once to avoid excess logging. Affected file is
2505 lib/silcutil/silclog.c.
2507 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2508 the SIM copying in make install in Makefile.am.pre.
2510 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2512 * Rewritten silclog APIs. Globally interesting changes follows:
2513 silc_log_set_files() changed to silc_log_set_file().
2514 silc_log_set_callbacks() changed to silc_log_set_callback().
2515 ROBOdoc documented silclog header file.
2516 SilcLogCb now returns bool to wether inihibit the default
2517 handler or not (to keep the old behaviour return always TRUE).
2518 The new APIs should also fix the problem of the
2519 silcd_error.log file that was written in the current directory.
2522 Log files streams will remain opened after silc_log_set_file()
2523 call, means less CPU usage notably on high traffic servers.
2524 File streams are now full buffered, and flushed to the disk
2525 every 5 minutes, lesses HD activity and CPU usage.
2526 Messages can be redirected, allowing admins to configure
2527 one single logfile for all server messages.
2528 the silc_log_quick global variable to activate fast-logging.
2529 Affected files lib/silcutil/silclog.[ch]
2531 * Changed some code to conform new silclog APIs. Affected
2532 files are doc/example_silcd.conf.in, silcd/server.c
2533 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2536 * Fixed a memory leak that could occur in some situations.
2537 Affected file silcd/serverconfig.c.
2539 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2541 * Added the silc_client_del_client to remove the client from
2542 all channels as well. Affected file lib/silcclient/idlist.c.
2544 * Fixed the client library to correctly remove the client
2545 from all channels when the client entry is being destroyed.
2546 Affected file lib/silcclient/client_notify.c, command.c.
2548 * Added auto-nicking support to the client library. If the
2549 applicatio now sets client->nickname it will be sent to the
2550 server after connecting by the library. This way for example
2551 SILCNICK (or IRCNICK) environment variables will have effect
2552 and always change the nickname automatically to whatever
2553 it is wanted. Affected file lib/silcclient/client.[ch].
2555 * Renamed silc_server_command_bad_chars to the
2556 silc_server_name_bad_chars and moved it to the
2557 silcd/server_util.[ch]. Added also new function
2558 silc_server_name_modify_bad to return nickname that
2559 includes bad characters as new nickname without those
2560 bad characters. This check and modify is now used in
2561 silc_server_new_client when the username is initially set
2562 as nickname, so it must be checked to be valid nickname.
2563 Affected file silcd/packet_receive.c.
2565 * The nickname length is now taken from the packet for real
2566 and not trusted to strlen() since it clearly can return
2567 wrong length for nickname including bad characters. This
2568 also applies to channel names. Affected file silcd/command.c.
2570 * Removed the lib/silcsilm/modules directory. Modules are now
2571 compiled into the lib/silcsim. Fixed the copying of the
2572 modules to follow symbolic links in Makefile.am.pre.
2574 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2576 * Fixed silc_string_regexify list creation. Fixes bugs with
2577 BAN and INVITE commands in server. The affected file is
2578 lib/silcutil/unix/silcunixutil.c.
2580 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2582 * Removed the command destructor entirely from the server's
2583 command and command reply routines. It is not needed, and
2584 its usage was buggy and caused crashes. Affected files are
2585 silcd/command[_reply].[ch].
2587 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2589 * Cancel protocol and NULL sock->protocol if timeout
2590 occurred during protocol. Affected file silcd/server.c.
2592 * Cancel protocol timeouts always before calling the final
2593 callback, to assure that after final callback is called
2594 no other state will be called for the protocol anymore.
2595 Affected file silcd/protocol.c.
2597 * Print error log if incoming connection configuration could
2598 not be found. Affected file silcd/server.c.
2600 * Fixed JOIN command to correctly save the founder mode
2601 to the client on normal SILC server, when the channel
2602 was created by the router. Affected file silcd/command.c.
2604 * Fixed LIST command (hopefully) to send correct reply
2605 packets. Affected file silcd/command.c.
2607 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2609 * The silc_packet_receive_process now returns FALSE if the
2610 read data was invalid packet, and TRUE if it was ok.
2612 The server now checks that if unauthenticated connection
2613 sends data and its processing fails the server will close
2614 the connection since it could be a malicious flooder.
2616 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2618 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2620 * Make sure the warning about error opening a log file is
2621 printed only once and not everytime it fails (produces
2622 too much useless log). Affected file lib/silcutil/silclog.c.
2624 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2626 * Made the silc_server_daemonise() function more readable.
2627 Affected file silcd/server.c.
2629 * Pid file is now optional, the user may comment it out from
2630 the config file. Removed define SILC_SERVER_PID_FILE, we
2631 don't need a default any longer. Affected file
2632 configure.in.pre, lib/Makefile.am.pre.
2634 * Make some use of the pid file. The server now dies at startup
2635 if it detects a valid pid file on his path. The server would
2636 die anyway in this circumstance, because of the bind() failure.
2637 Affected file silcd/silcd.c.
2639 * No longer compiling lib/dotconf.
2641 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2643 * Fixed JOIN command parsing not to crash. Affected file
2644 lib/silcclient/command.c.
2646 * Fied the NICK_CHANGE notify to add the new client entry
2647 even it is resolved. This removes an <[unknown]> nick
2648 thingy bug in the client. Affected file is
2649 lib/silcclient/client_notify.c.
2651 * Do not try to allocate 0 bytes (efence does not like it)
2652 in lib/silccore/silccomand.c when encoding payload.
2654 * Do not take IRCNICK as nickname in Irssi SILC client since
2655 it is not possible to set nickname before hand connecting
2656 the server (TODO has an entry about adding auto-nicking
2659 * Changed the silc_server_command_pending to check whether
2660 there already exists an pending entry with the specified
2661 command, command identifier and pending callback. This is
2662 to fix IDENTIFY and WHOIS related crashes that may register
2663 multiple pending commands with same identifier. Affected
2664 file silcd/command.c.
2666 * Fixed the server to reconnect to the router even if it
2667 was already reconnecting and EOF was received. This to
2668 fix a possibility that the server wouldn't ever try to
2669 auto-reconnect to the router. Affected file silcd/server.c.
2671 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2673 * Fixed the server's password authentication to use the
2674 length of the locally saved password, and not the one
2675 sent in the packet. Affected file silcd/protocol.c.
2677 * Fixed same password authentication problem in the
2678 Authentication Payload handling routines in
2679 lib/silccore/silcauth.c.
2681 * Yet another password authentication problem fixed with
2682 channel password handling in silcd/command.c.
2684 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2686 * If first character of string in silc_parse_userfqdn is '@'
2687 then do not parse it. Affected file is
2688 lib/silcutil/silcutil.c.
2690 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2692 * Fixed minor bug in IDENTIFY command reply sending, which
2693 caused various weird problems during JOIN when it was
2694 resolving names for users. Affected file silcd/command.c.
2696 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2698 * Fixed the IDENTIFY command reply sending to chech better valid
2699 clients. It was possible to send incomplete list of replies.
2700 Affected file silcd/command.c.
2702 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2704 * Added silc_client_command[s]_[un]register functions now to
2705 dynamically register the commands in client library. Removed
2706 the static table of commands. This allows the client library
2707 to call commands without causing the application to know about
2708 what commands library has called.
2710 Removed the INFO command reply kludge to detect when the command
2711 was called by library. Now library use its own command reply
2712 function for INFO command.
2714 Added function silc_client_command_call to call a command.
2715 Application can use it to call command, not access the structure
2718 Now all commands that are sent by the client library (not
2719 explicitly sent by application) use own command reply functions.
2721 Affected files around lib/silcclient/ and in
2722 irssi/src/silc/core/.
2724 * Fixed the WHOIS command reply sending to chech better valid
2725 clients. It was possible to send incomplete list of replies.
2727 Fixed the WHOIS and IDENTIFY to send the request to router
2728 if normal server did not do it and did not find any results.
2730 Affected file silcd/command.c.
2732 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2734 * Moved the internal data from SilcClient context into its
2735 own file, not accesible to application. Affected files
2736 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2737 and other files in client library.
2739 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2741 * Added doc/examples installation target in Makefile.am.pre.
2744 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2746 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2747 commands the found client entry will be removed from the
2748 cache, after notifying application about the error. Affected
2749 file lib/silcclient/command_reply.c.
2751 * Changed the /MSG to check for exact nickname user gave, and
2752 not let `nick' match `nick@host' if it is only one found. Now,
2753 user must type the exact nickname (like nick@host2) even if
2754 there are no more than one same nicks found. This is to avoid
2755 a possibility of sending nickname to wrong nickname since
2756 `nick' could match `nick@host'. Affected file is
2757 irssi/src/core/silc-servers.c.
2759 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2761 * Do not print "you are now server operator" or similar when
2762 giving /away command. Affected files are
2763 irssi/src/silc/core/client_ops.c, silc-servers.h.
2765 * Made the silc_server_command_pending_error_check to send
2766 the same command reply payload it received back to the
2767 original sender of the command. This way all arguments
2768 that was received by the server will be received by the
2769 client too. Affected file silcd/command.c.
2771 * Added the silc_idcache_add to return the created cache entry
2772 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2774 * Add global clients to expire if they are not on any channel.
2775 This is because normal server will never know if they signoff
2776 if they are not on any channel. The cache expiry will take
2777 case of these entries. This is done by normal servers only.
2778 The affected files are silcd/command_reply.c,
2779 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2781 * If server receives invalid ID notification for WHOIS or
2782 IDENTIFY and the ID exists in the lists, it is removed.
2783 Affected file silcd/command_reply.c.
2785 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2786 in client then client entry that it matches is searched and
2787 the nickname is printed on the screen for user. Affected
2788 file irssi/src/silc/core/client_ops.c.
2790 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2792 * Use cache entry expire time in the LIST command reply to
2793 purge old entries from the cache after the LIST command
2794 reply has been received. This way we don't have non-existent
2795 entries in the cache for too long. Affected file is
2796 silcd/command_reply.c.
2798 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2800 * If we are normal server, and we've not resolved client info
2801 in WHOIS or IDENTIFY from router, and it is global client,
2802 we'll check whether it is on some channel. If it is not
2803 then we cannot be sure about its validity and will resolve it
2804 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2805 file silcd/command.c.
2807 * Search channel by name (if possible) rather than by ID
2808 in IDENTIFY command's command reply. Affected file is
2809 silcd/command_reply.c.
2811 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2813 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2814 Updated specs and implemented it. Affected file silcd/command.c,
2815 silcd/packet_send.c and silcd/packet_receive.c.
2817 * Implemented the <founder auth> payload handling in the JOIN
2818 command. If provided all conditions for channel joining
2819 except requirement to provide correct passphrase can be
2820 overrided by the channel founder. Updated the protocol specs.
2821 Affected file silcd/command.c.
2823 Added support for founder auth in JOIN command in client
2824 library. Fixed the parsing of the JOIN command now to support
2825 all options as they should be. The affected file is
2826 lib/silcclient/command.c.
2828 * Optimized the WHOIS and IDENTIFY commands to send the request
2829 to router only if it includes nicknames or other names. If
2830 they include only IDs then check the local cache first before
2831 routing. Affected file is silcd/command.c.
2833 * Added channels topic announcements. Affected file is
2834 silcd/packet_receive.c and silcd/server.c.
2836 * Fixed the silc_server_send_notify_topic_set to really destine
2837 the packet to channel. Affected file silcd/packet_send.c.
2839 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2840 library. Affected file lib/silcclient/client_notify.c.
2842 * Added UMODE announcements. Affected file silcd/server.c.
2844 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2846 * Memory leak fixes in:
2848 lib/silcutil/silcsockconn.c
2849 lib/silcske/silcske.c
2850 lib/silcske/groups.c
2852 lib/silccrypt/silcpkcs.c
2853 lib/silccore/silccommand.c
2854 lib/silccore/silcidcache.c
2859 * ROBOdoc documented the lib/silcske/groups.h file and a
2860 bit changed the interface for better.
2862 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2864 * Update the client entry context in the ID cache after
2865 nick change. Affected file lib/silcclient/command.c.
2866 Fixes the CUMODE command when regaining founder privileges,
2867 and a little WHOIS problem.
2869 * Fixed silc_net_gethostbyname to correctly call the
2870 inet_ntop. Affected file lib/silcutil/silcnet.c.
2872 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2874 * Added IPv6 support checking to the configure.in.pre, added
2875 also --enable-ipv6 option to override the check. Affected
2876 file configure.in.pre.
2878 * The silc_thread_create now calls the start function
2879 directly if threads support is not compiled in. Removes
2880 ugly #ifdef's from generic code. Affected files are
2881 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2883 * Added silc_net_gethostby[name/addr]_async to asynchronously
2884 resolve. Affected files are lib/silcutil/silcnet.[ch].
2886 * Added support for rendering IPv6 based server, client and
2887 channel IDs. Affected file lib/silcutil/silcutil.c.
2889 * Added support for creating IPv6 based server IDs. Affected
2890 file is silcd/serverid.c.
2892 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2894 * Added silc_net_gethostby[addr/name] into the
2895 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2896 routines. Added silc_net_is_ip[4/6]. Affected file is
2897 lib/silcutil/unix/silcunixnet.c. All routines that take
2898 address as argument now supports both IPv4 and IPv6 addresses.
2900 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2902 * Fixed LIST command reply sending in server. Affected file
2905 * Server now sends the kicker's client ID in the KICK notify
2906 to the kicked client. Affected file silcd/command.c.
2908 * The client library now parses the kickers client ID and
2909 UI displays it. Affected files lib/silcclient/client_notify.c
2910 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2912 * Made all payload parsing function prototypes consistent.
2913 They all take now const unsigned char * and uint32 pair as
2914 the payload data instead of SilcBuffer. Changes all around
2915 the source tree. Other unsigned char* -> const unsigned char*
2916 changes around the tree as well.
2918 * Optimized SFTP client and server packet sending not to
2919 allocate new buffer for each packet but to recycle the
2920 first allocated buffer. Affected files are
2921 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2923 * Optimized the SFTP client to use SilcList instead of
2924 SilcDList for requests, because it is faster. Affected file
2925 is lib/silcsftp/sftp_client.c.
2927 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2928 into lib/silccore/silcid.[ch].
2930 Renamed silcpayload.[ch] into silcargument.[ch].
2932 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2934 * If client entry is deleted with active key agreement
2935 session, abort the session.
2937 The silc_client_abort_key_agreement now calls the completion
2938 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2940 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2943 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2945 * Don't use __restrict in older GCC's. Affected file is
2946 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2948 * silc_net_localhost now attempts to reverse lookup the
2949 IP/hostname. Affected file lib/silcutil/silcnet.c.
2951 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2952 command. It can be used to gain founder privileges at
2953 the same time when joining the channel.
2955 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2956 kicker's client ID as well. Updated protocol specs.
2958 Defined that the server must send SILC_COMMAND_IDENTIFY
2959 command reply with error status to client who sent
2960 private message with invalid client ID.
2962 Updated the protocol specification.
2964 * Added silc_server_send_command_reply to send any
2965 command reply. Affected file silcd/packet_send.[ch].
2967 * Added silc_id_payload_encode_data to encode ID payload
2968 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2970 * The server now send IDENTIFY command reply with error
2971 status if client ID in private message is invalid. Affected
2972 file silcd/packet_receive.c.
2974 * Save the server key file with server's IP address in
2975 the filename instead of hostname. The affected file is
2976 irssi/src/silc/core/client_ops.c.
2978 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2980 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2983 * Added libtool support for compiling shared objects in
2984 lib/silcsim. Affected file configure.in.pre and
2985 lib/silcsim/Makefile.am. Original patch by cras.
2987 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2989 * Pid file configuration, and server's config file fixes
2990 patch by toma. Updated CREDITS file.
2992 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2994 * Fixed silc_client_channel_message to not try to decrypt
2995 the message twice if it resolved the destination client
2996 information. This could cause of dropping one channel
2997 message. Affected file lib/silcclient/client_channel.c.
2999 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3001 * Added silc_client_run_one into lib/silcclient/silcapi.h and
3002 lib/silcclient/client.c. This function is used when the SILC
3003 Client is run under some other scheduler, or event loop or
3004 main loop. On GUI applications, for example this may be
3005 desired to used to run the client under the GUI application's
3006 main loop. Typically the GUI application would register an
3007 idle task that calls this function multiple times in a second
3008 to quickly process the SILC specific data.
3010 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
3012 * Fixed silc_server_drop() for dropping the supplementary
3013 groups as well, this could cause a security hole on some
3016 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3018 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

3029 Affected file irssi/src/silc/core/client_ops.c.
3031 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3033 * Fixed the silc_idcache_list_* routines to really support
3034 the dynamic list. Fixes a crash. Affected file is
3035 lib/silccore/silcidcache.c.
3037 * Fixed the LIST command reply to really call LIST command's
3038 pending callbacks. Affected file silcd/command_reply.c.
3040 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3042 * Update conn->local_entry->nickname after giving NICK
3043 command. Affected file lib/silcclient/command.c.

3047 * Added the [pid] option to the silcd configuration file
3049 Affected files: serverconfig.[ch] and silcd.c
3051 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3053 * Save fingerprint in WHOIS command reply in server.
3054 Affected file silcd/command_reply.c.
3056 * Fixed NICK commands pending callback registration.
3057 Affected file lib/silcclient/command.c.
3059 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3061 * Use ++server->cmd_ident when sending commands in server,
3062 instead of random number. Affected file silcd/command.c.
3064 * Fixed GETKEY command reply to call actually GETKEY pending
3065 command callbacks. Affected file silcd/command_reply.c.
3067 * A bit stricter check for nicknames. Check for same nickname
3068 in NICK command also. Affected file silcd/command.c.
3070 * Do not call INFO command everytime client ID changes, only
3071 during first connecting. Affected file lib/silcclient/client.c.
3073 * Set the new nickname only after successful command reply for
3074 NICK command is returned by server. Affected file
3075 lib/silcclient/command.c.
3077 * Remove nicknames from nicklist during server_signoff notify.
3078 Should fix /NAMES bit more. The affected file is
3079 irssi/src/silc/core/silc-channels.c.
3081 * Added `fingerprint' field to the SilcIDListData in the
3082 silcd/idlist.h to hold the fingerprint of the client's
3085 Send the fingerprint of the client's public key in WHOIS
3088 Affected files silcd/command.c, and silcd/idlist.[ch].
3090 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3091 create fingerprint from given data.
3093 * Show the fingerprint of the client's public key in WHOIS.
3094 Affected files irssi/src/module-formats.[ch] and
3095 irssi/src/silc/core/client_ops.c.
3097 * Format the multiple same nicknames also during JOIN and
3098 NICK_CHANGE notifys. Affected file is
3099 lib/silcclient/client_notify.c.
3101 * Do not print error on screen for invalid private message
3102 payload since it can come if someone is sending private
3103 messages with wrong key. Affected file
3104 lib/silccore/silcprivate.c.
3106 * Fixed multiple concurrent /PING crash. Affected file
3107 lib/silcclient/command.c.
3109 * Changed the wrong ID encoding. All IP addresses must be
3110 in MSB first order in encoded format. They were encoded
3111 wrong and was in LSB format. Affected files are
3112 silcd/serverid.c, lib/silcutil/silcutil.c.
3114 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3116 * Call the `connect' client operation through the scheduler
3117 in case of error. Affected file lib/silcclient/client.c.
3119 * Call the `failure' client operation even if the error
3120 occurred locally during a protocol. Affected file is
3121 lib/silcclient/protocol.c.
3123 * Added support of sending LIST command to router from normal
3124 server. This way normal server can get list of all channels
3125 in the network too. Fixed the channel list sending in the
3126 server too. Affected files are silcd/command.c, and
3127 silcd/command_reply.[ch].
3129 * Added silc_server_update_channels_by_server and
3130 silc_server_remove_channels_by_server. They are used during
3131 disconnection of primary router and in backup router protocol.
3132 Affected file silcd/server_util.[ch], silcd/server.c and
3133 silcd/server_backup.c.
3135 * Fixed channel adding to global list in IDENTIFY command
3136 reply in server. Affected file silcd/command_reply.c.
3138 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3140 * If the incoming packet type is REKEY or REKEY_DONE process
3141 that packet always synchronously. Fixes yet another MAC
3142 failed error on slow (dialup) connections. Affected file
3143 lib/silcclient/client.c and silcd/server.c.
3145 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3147 * Call check_version SKE callback for initiator too. Affected
3148 file lib/silcske/silcske.c.
3150 * Implemented fix for security hole found in the SKE that was
3151 fixed in the specification few days back; the initiator's
3152 public key is now added to the HASH value computation.
3153 Added backwards support for the old way of doing it too, for
3154 old clients and old servers. Affected file is
3155 lib/silcske/silcske.c.
3157 * Enabled mutual authentication by default in SKE. If initiator
3158 is not providing mutual authentication the responder will
3159 force it. This will provide the proof of posession of the
3160 private key for responder. The affected files are
3161 lib/silcclient/protocol.c and silcd/protocol.c.
3163 * Do not cache anymore the server's public key during SKE.
3164 We do mutual authentication so the proof of posession of
3165 private key is done, and if the server is authenticated in
3166 conn auth protocol with public key we must have the public
3167 key already. Affected file silcd/protocol.c.
3169 * Added new global debug variable: silc_debug_hexdump. If
3170 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3171 file lib/silcutil/silclog.[ch].
3173 * Fixed compilation warning due to char * -> const char *.
3174 Affected files lib/silcutil/silcnet.h, and
3175 lib/silccore/silcauth.[ch].
3177 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3179 * Fixed CMODE command when new channel key was created. If
3180 the creation failed the old key was removed. Next time giving
3181 same command would crash the server since the old key was
3182 freed already. Affected file silcd/command.c.
3184 * Fixed the silc_server_announce_get_channels to not crash
3185 on reconnect. Affected file silcd/server.c.
3187 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3189 * Added silc_log_set_debug_string function to set a regex
3190 string to match for debug output. Only the function names,
3191 or filenames matching the given debug string is actually
3192 printed. This way it is possible to filter out those debug
3193 strings that user is not interested in.
3195 Fixed a bug in silc_string_regexify.
3197 Affected files lib/silcutil/silclog.[ch], and
3198 lib/silcutil/unix/silcunixutil.c.
3200 * Changed the -d options in both server and Irssi SILC client
3201 to take the debug string as argument. Affected files
3202 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3204 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3206 * Added silc_hash_babbleprint to create a Bubble Babble
3207 Encoded fingerprint. The encoding is developed by Antti
3208 Huima (draft-huima-babble-01.txt), and it creates human
3209 readable strings out of binary data. Affected file
3210 lib/silccrypt/silchash.[ch].
3212 * Print the babble print now in addition of fingerprint as well
3213 in Irssi SILC client. Affected files are
3214 irssi/src/fe-common/silc/module-formats.[ch],
3215 irssi/src/fe-common/silc/core/client_ops.c.
3217 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3219 * Fixed a security problem found in SKE. The initiator's
3220 public key too is now added to the HASH hash value creation
3221 which is signed by the responder to create the SIGN value.
3222 This will prevent anyone in the middle to lie to the responder
3223 about the initiator's public key. If this is done now, the
3224 man in the middle will get caught. Updated the protocol
3227 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3229 * Better installation directory handling. Configure module
3230 paths and other paths automatically to example_silc* files
3231 in doc/. A patch by toma.
3233 * Fixed compiler warning from MPI library, and from SILC RNG.
3236 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3237 It can be configured with ./configure. A patch by toma.
3239 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3241 * Find correct make to use in prepare-clean. A patch by
3242 toma. Affected file prepare-clean.
3244 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3246 * Added irssi variables use_auto_addr, auto_bind_ip,
3247 auto_bind_port and auto_public_ip.
3249 * Changed the interface for silc_client_send_key_agreement
3250 in lib/silcclient/silcapi.h
3254 irssi/src/silc/core/silc-core.c
3256 lib/silcclient/silcapi.h
3257 irssi/src/silc/core/silc-channels.c
3258 lib/silcclient/client_keyagr.c
3261 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3263 * Added silc_pkcs_public_key_compare to compare two
3264 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3266 * Check that the client who set the founder mode on the
3267 channel is the same client that is giving the founder
3268 mode to itself. It is done by comparing the saved public
3269 key (it is saved even in the authentication is passphrase).
3270 Affected file silcd/command.c.
3272 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3274 * Do not process packet for disconnected socket connection.
3275 Affected file lib/silccore/silcpacket.c.
3277 * Process the DISCONNECT packet through scheduler in the
3278 client library. Affected file lib/silcclient/client.c.
3280 * Fixed the silc_client_packet_parse to not to increase
3281 the packet sequence number if the conn->sock and the
3282 current socket connection is not same. This can happen
3283 for example during key agreement when the conn includes
3284 multiple socket connections (listeners). Affected file
3285 lib/silcclient/client.c.
3287 * The sender of the file transfer request now provides also
3288 the pointer (listener) for the key exchange protocol. If
3289 the listener cannot be created then it sends empty key
3290 agreement and lets the receiver provide the listener.
3292 Added `local_ip' and `local_port' arguments to the
3293 silc_client_file_send. If they are provided they are used,
3294 if not then it will attempt to find local IP address, if
3295 not found or bind fails then the remote client will provide
3298 Affected files are lib/silcclient/client_ftp.c and
3299 lib/silcclient/silcapi.h.
3301 * Extended the FILE SEND command to support defining the
3302 local IP and port for key exchange listener. They are
3303 optional. Affected file irssi/src/silc/core/silc-servers.c.
3305 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3307 * Defined to WHOIS command reply the sending of fingerprint
3308 of the client's public key (if the proof of posession of the
3309 corresponding private key is verified by the server).
3310 Updated to the protocol specification.
3312 * Added support of receiving the client's public key's
3313 fingerprint in command reply in client library. Affected
3314 file is lib/silcclient/command_reply.c, and
3315 lib/silcclient/idlist.[ch].
3317 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3319 * Do not send over 128 chars long nickname to the server
3320 in NICK command. Affected file lib/silcclient/command.c.
3322 * Do not send over 256 chars long channel names to the server
3323 in JOIN command. Affected file lib/silcclient/command.c.
3325 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3327 * Assure that silc_server_close_connection cannot be called
3328 twice for same socket context. Affected file is
3331 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3333 * Send error message to application if opening file for
3334 writing during file transfer fails. Affected file is
3335 lib/silcclient/client_ftp.c.
3337 Remove all file transfer sessions for a client that we're
3338 removing from ID cache.
3340 Affected file is lib/silcclient/client_ftp.c.
3342 * Fixed silc_net_addr2bin to return correct address. Affected
3343 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3345 * Fixed file transfer session removing on signoff notify.
3346 Affected file irssi/src/silc/core/silc-servers.c.
3348 * Added the SilcClientFileError to be returned in the monitor
3349 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3350 Affected file lib/silcclient/silcapi.h.
3352 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3354 * Fixed a crash in silc_client_ftp_free_sessions and
3355 silc_client_ftp_session_free_client. Affected file
3356 lib/silcclient/client_ftp.c.
3358 * Added `disabled' field in the SilcChannelEntry in the server
3359 to indicate if the server entry is disabled. Affected file
3360 silcd/idlist.h, silcd/command[_reply].c.
3362 * SILC server adds now /var/run/silcd.pid everytime it is
3363 started. Affected file silcd/silcd.c.
3365 * Added silc_server_packet_send_clients to send a packet to
3366 the provided table of client entries. Affected file
3367 silcd/packet_send.[ch].
3369 * Fixed a crash in client resolving in client_prvmsg.c in
3370 client library. Affected file lib/silcclient/client_prvmsg.c.
3372 * Do not actually remove the client directly from ID cache
3373 during SERVER_SIGNOFF, but invalidate it. This way we
3374 preserve the WHOWAS info for the client. Affected file
3375 silcd/server_util.c.
3377 * Fixed SERVER_SIGNOFF notify handling in the server. The
3378 server is now able to process incoming SERVER_SIGNOFF notify
3379 for a server that it doesn't even know about. It will remove
3380 the clients provided in the notify. Affected file
3381 silcd/packet_receive.c.
3383 * Check for partial packet in data queue after every packet that
3384 was found from the queue. Return and wait for more data if
3385 there is partial data in queue. Affected file is
3386 lib/silccore/silcpacket.c.
3388 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3390 * Added SilcClietFileError enum to indicate error in
3391 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3392 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3393 Affected files lib/silcclient/silcapi.h and
3394 lib/silcclient/client_ftp.c.
3396 * Check that newsize in silc_buffer_realloc is larger than
3397 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3399 * Added better monitor of file transfers. It now monitors
3400 key agreement protocol during the file transfer too. Added
3401 error reporting too. Affected files
3402 irssi/src/silc/core/silc-servers.c,
3403 irssi/src/fe-common/silc/module-formats.[ch].
3405 * Wrote a help file for FILE command.
3407 * Added silc_rng_global_get_byte_fast to get not-so-secure
3408 random data as fast as possible. Random data is read from
3409 /dev/urandom if available and from the SILC RNG if not
3410 available. It is used in padding generation. Affected file
3411 lib/silccrypt/silcrng.[ch].
3413 * All packets in client library are now processed synchronously.
3414 Optimized packet processing a lot. Affected file
3415 lib/silcclient/client.c.
3417 * All server connection packets are processing synchronously
3418 now in server, to optimize packet processing. Affected file
3421 * Include files are installed now only in Toolkit distribution
3422 if make install is given. Affected files: all Makefile.am's.
3424 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3426 * Assure that silc_client_notify_by_server_resolve does not
3427 resolve the client information multiple times. If it cannot
3428 be found by the first it cannot be found at all. Affected
3429 file lib/silcclient/client_notify.c.
3431 * Fixed WHOWAS command reply calling. Affected file
3432 lib/silcclient/command_reply.c.
3434 * Removed all references to silc_idlist_get_client from the
3435 Irssi SILC client since that call is internal call used by
3436 the library. The Irssi SILC client will use now client
3437 retrieval functions found in silcapi.h.
3439 * Fixed a bug in resolving nickname info before sending
3440 private message. It used freed memory. Affected file
3441 irssi/src/silc/core/silc-servers.c.
3443 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3445 * Assure my_channels statistics cannot go negative in server.
3446 Affected files silcd/server.c, silcd/server_util.c.
3448 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3450 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
3452 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3454 * Win32 Toolkit changes. Affected files
3455 win32/silc.dsw, win32/libsilc/libsilc.def,
3456 win32/libsilcclient/libsilc.def,
3457 lib/silcutil/silcutil.c, and
3458 lib/sftp/sftp_fs_memory.c.
3460 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3462 * Added silc_net_localip to return local host's IP address.
3463 Affected file lib/silcutil/silcnet.[ch].
3465 * If key exchange or rekey protocol is active for a connection
3466 parse all packets syncronously since there might be packets
3467 in packet queue that we are not able to process without first
3468 processing packets before them. Affected file silcd/server,
3469 lib/silcclient/client.c.
3471 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3472 whether library should continue processing the packet.
3473 Affected file lib/silccore/silcpacket.h.
3475 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
3476 SilcSFTPMonitorData to SFTP server to monitor various
3477 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
3478 lib/silcsftp/sftp_server.c.
3480 * Added silc_file_size to return file size. Affected file
3481 lib/silcutil/silcutil.[ch].
3483 * Implemented the file transfer support for the client library.
3484 Added preliminary support for simple client to client one-file
3485 transmission. Affected file lib/silcclient/client_ftp.c,
3486 lib/silccilent/client.[ch].
3488 * Added new local command FILE to the Irssi SILC Client.
3489 It is used to perform the file transfer. It has subcommands
3490 SEND, RECEIVE, SHOW and CLOSE. Affected files
3491 irssi/src/silc/core/client_ops.c,
3492 irssi/src/silc/core/silc-server.[ch].
3494 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3496 * Relay the SILC_PACKET_FTP in the server. Affected files
3497 silcd/server.c and silcd/packet_receive.c.
3499 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3501 * Renamed silc_file_read and silc_file_write to functions
3502 silc_file_readfile and silc_file_writefile. Added function
3503 silc_file_open and silc_file_close. Affected files
3504 lib/silcutil/silcutil.[ch].
3506 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3508 * Resolve the client info when received private message or
3509 channel message for a client which nickname we don't know.
3510 Affected files lib/silcclient/client_prvmsg.c and
3511 lib/silcclient/client_channel.c.
3513 * Do not crash in /KEY if client is not connected. Affected
3514 file irssi/src/silc/core/silc-channels.c.
3516 * Added SilcClientStatus field to the SilcClientEntry in the
3517 lib/silcclient/idlist.h.
3519 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3520 is incomplete and is being resolved, it won't be resolved
3523 Make sure also that USERS command reply does not resolve
3524 twice information. Affected file is
3525 lib/silcclient/command_reply.c.
3527 Make sure that silc_client_get_clients_by_list does not
3528 resolve twice same information.
3530 * Check for valid client->id in the silc_server_free_client_data.
3531 Affected file silcd/server.c.
3533 * Fixed /GETKEY nick@server not to crash if the server entry
3534 is not found. Affected file lib/silcclient/command.c.
3536 * Fixed the silc_server_check_cmode_rights to check the
3537 requested modes correctly. Affected file silcd/command.c.
3539 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3541 * Better checks for non-printable chars in nick added.
3542 Affected file silcd/command.c.
3544 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3546 * Call the silc_server_udpate_servers_by_server in the
3547 primary router that comes back online in the backup resuming
3548 protocol. Otherwise it routes packets wrong. Affected file
3549 silcd/server_util.[ch], silcd/server_backup.c.
3551 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3553 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3554 lib/silcutil/silcbuffmt.[ch].
3556 * Redefined the SILC packet header to include the padding
3557 length. Affected file lib/silccore/silcpacket.[ch].
3559 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3560 length for maximum padding up to 128 bytes). Affected
3561 file lib/silccore/silcpacket.h.
3563 * Removed all backwards support for old 0.5.x MAC thingies.
3564 The SILC packet header change makes it impossible to be
3565 backwards compatible.
3567 * Send the ENDING packet with timeout in the backup resuming
3568 protocol. This is to assure that all routers has connected
3569 to the primary router. Affected file silcd/server_backup.c.
3571 * Changed the RNG to take the first IV from random data. It
3572 used to take it from zero actually. Changed the RNG also
3573 to use /dev/urandom during session. /dev/random is used
3574 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3576 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3578 * Changed the SILC packet header to have the first two bytes
3579 (the packet length) encrypted. Affected files aroung the
3580 code tree, lib/silccore/silcpacket.[ch]. Removed the
3581 SilcPacketCheckDecrypt callback. It is not needed anymore
3582 since the silc_packet_receive_process will determine now
3583 whether the packet is normal or special.
3585 * Implemented the unidirectional MAC keys. Affected files
3586 lib/silcske/silcske.c, silcd/protocol.c and
3587 lib/silcclient/protocol.c.
3589 * Implemented the packet sequence number to the MAC computation.
3590 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3591 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3592 lib/silcclient/protocol.c.
3594 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3596 * Allow backup router to announce servers. All servers
3597 announced by backup router are added to the global list
3598 automatically. Update hte server's socket to our primary
3599 router also when backup router announces a server.
3600 Affected file silcd/packet_receive.c.
3602 * Do not update the client->router in the function
3603 silc_server_udpate_clients_by_server if the client is on
3604 global list. We might fail to find any specific server
3605 for locally connected clients and local cell clients. They
3606 should still use the `from' and not `to' as client->router.
3607 This fixes backup router resuming protocol. Affected file
3608 silcd/server_util.c.
3610 * Decrease channel statistics count only if the channel
3611 deletion worked. Affected files are silcd/server.c and
3612 silcd/server_util.c.
3614 * Added silc_server_update_servers_by_server to update origin
3615 of all server entries. Used during backup router protocol.
3616 Affected files silcd/server_util.[ch], silcd/server.c. and
3617 silcd/backup_router.c.
3619 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3620 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3621 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3622 lib/silccrypt/silchmac.c.
3624 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3626 * Assure that router cannot reroute the same channel message
3627 to the sender. Affected file silcd/packet_receive.c.
3629 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3631 * Made better checks that the channel message is not sent
3632 to the router it came from. Affected file is
3633 silcd/packet_send.c. Fixed memory leak too.
3635 * Announce informations for incoming router connection, but
3636 only after checking if it is replaced by backup router.
3637 Affected file silcd/packet_receive.c.
3639 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3641 * Fixed the backup resuming protocol to work in multiple
3642 router environment. Affected file silcd/server_backup.c.
3644 * Route packet only to one router in the function
3645 silc_server_packet_send_to_channel. Affected file is
3646 silcd/packet_send.c.
3648 * Fixed silc_server_send_notify_dest to set the broadcast
3649 flag. Fixed the silc_server_send_notify_topic to actually
3650 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3651 Affected file silcd/packet_send.c.
3653 * Changed the SFTP Filesystem interface. Changed the
3654 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3655 the filesystem operation function. The SilcSFTPFilesystem
3656 is now a context that is allocated by all filesystem allocation
3657 functions and it already includes the operations structure
3658 and filesystem specific context. It is given as argument
3659 now to the silc_sftp_server_start. This made the interface
3660 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3661 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3663 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3665 * Changed the backup router adding and getting interfaces
3666 in the server. The router that will be replaced by the
3667 specified backup router is now sent as argument. Affected
3668 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3671 * Added silc_net_addr2bin_ne to return the binary form of
3672 the IP address in network byte order. Affected files
3673 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3675 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3677 * Check for existing server ID in silc_server_new_server
3678 and in silc_server_connect_to_router_final and remove the
3679 old entry if it exists. Affected file silcd/packet_receive.c,
3682 * Send the channel message always to only one router, either
3683 in upstream or downstream. Affected file is
3684 silcd/packet_send.c.
3686 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3688 * Wrote the definition of the backup resuming protocol to the
3689 protocol specification.
3691 * Removed one redundant channel key generation from normal
3692 server during joining procedure. Removed one redundant
3693 channel key sending from server to router during joining
3694 procedure. Affected file silcd/command.c.
3696 * Made minor bugfixes to the backup router resuming protocol.
3697 Affected file silcd/server_backup.c, server.c.
3699 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3701 * Added --disable-asm configuration option. Affected files
3702 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3705 * Implemented the backup resuming protocol that is used to
3706 resume the primary router position in the cell after the
3707 primary router comes back online. Affected files
3708 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3709 and silcd/server_util.[ch].
3711 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3713 * Sleep two (2) seconds after sending QUIT command to server.
3714 Affected file lib/silcclient/command.c.
3716 * Assure that if outgoing data buffer is pending do not force
3717 send any data. Affected file silcd/packet_send.c.
3719 * Assure that if outgoing data buffer is pending do not force
3720 send any data. Affected file lib/silcclient/client.c.
3722 * Implemented the backup router support when the primary router
3723 goes down. The servers and routers can now use the backup
3724 router as new primary router without loosing connectivity.
3726 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3728 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3729 in the server to indicate disabled entry. All data read
3730 from the connection will be ignored and no data is sent
3731 for entry that is disabled. Affected files are
3732 silcd/idlist.h, silcd/server.c.
3734 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3736 * Created SFTP client and server test programs in the
3737 lib/silcsftp/tests directory.
3739 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3741 * Implemented memory filesystem (virtual filesystem) for
3742 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3745 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3747 * Implemented the SFTP (SSH File Transfer Protocol) to the
3748 lib/silcsftp. It includes SFTP client and SFTP server
3751 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3753 * Moved lib/silccore/silcprotocol.[ch] to the
3754 lib/silcutil library.
3756 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3757 take variable argument list pointer as argument. Affected
3758 file lib/silcutil/silcbuffmt.[ch].
3760 * Added silc_buffer_set function that is used to set data
3761 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3762 Affected file lib/silcutil/silcbuffer.h.
3764 * Changed various routines in the core library to use the new
3765 silc_buffer_set instead of allocating new buffer only for
3768 * Added 64-bit value formatting and unformatting support to the
3769 silc_buffer_[un]format routines. Affected file is
3770 lib/silcutil/silcbuffmt.[ch].
3772 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3773 to includes/bitmove.h.
3775 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3777 * Fixed channel user mode saving in client library. Affected
3778 file lib/silcclient/command[_reply].c.
3780 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3782 * Defined the file transfer to the SILC Protocol. Added
3783 new packet type SILC_PACKET_FTP and defined File Transfer
3784 Payload. The mandatory file transfer protocol is SFTP
3785 (SSH File Transfer Protocol). Affected file in addition
3786 of the internet draft is lib/silccore/silcpacket.h.
3788 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3789 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3790 is used as part of backup router protocol when the primary
3791 router of the cell is back online and wishes to resume
3792 the position as primary router.
3794 * Redefined the MAC generation keys in the protocol. The
3795 same key is not used anymore in both direction. Both
3796 direction will now use different keys for sending and
3797 receiving. This fixes a potential security flaw. This
3798 change causes incompatibilities in the protocol.
3800 * Redefined also the MAC computation from the packet.
3801 An packet sequence number is now added to the MAC
3802 computation. This prevents possible replay attacks against
3803 the protocol. This change too causes incompatibilities
3806 Added `sequence' field to the SilcPacketContext to hold
3807 the current sequence number for the packet.
3809 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3811 * Added `created' field to the SilcIDListData in the file
3812 silcd/idlist.h to indicate the time when the entry was
3815 * Added `created' field to the SilcChannelEntry too. Affected
3816 file silcd/idlist.h.
3818 * Added `creation_time' aguments to all the announcement functions
3819 in the server. If it is provided then only the entries that
3820 was created after the provided time frame are actually
3821 announced. Affected file silcd/server.[ch].
3823 * The protocol says that the Channel ID's IP address must be
3824 based on the router's IP address. Added check for this in
3825 the silc_server_new_channel when processing incoming New Channel
3826 Payload. Affected file silcd/packet_receive.c.
3828 * Print out the correct version with --version in SILC client.
3829 Affected file irssi/src/silc/core/silc-core.c.
3831 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3833 * Fixed WHOWAS command to check for completnes of the client
3834 entry always, not just when the command is coming from client.
3835 Affected file silcd/command.c.
3837 * Added new function silc_server_packet_queue_purge to purge the
3838 outgoing data queue to the network. After the function returns
3839 it is guaranteed that the outgoing packet queue is empty.
3840 Affected file silcd/packet_send.[ch].
3842 * Purge the outgoing packet queue in the rekey protocol's final
3843 callback to assure that all rekey packets go to the network
3844 before quitting the protocol. Affected file silcd/server.c.
3846 * Added silc_client_packet_queue_parse as similar function as
3847 in server to the client library. The affected file is
3848 lib/silcclient/client.c.
3850 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3852 * Splitted silcd/server.c and created silcd/server_util.[ch]
3853 for utility functions.
3855 * Added new socket flag SILC_SF_DISABLED to indicate that the
3856 connection is open but nothing can be sent to or received from
3857 the connection. Affected file lib/silcutil/silsockconn.[ch].
3858 The checking for disabled socket is checked in the low level
3859 silc_socket_write and silc_socket_read functions.
3861 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3863 * Allow only nicknames and channel names that fits into the
3864 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3866 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3868 * When processing JOIN command reply in server check that if
3869 the channel exists in our global list we'll move it the local
3870 list. Affected file silcd/command_reply.c.
3872 * Fixed the check whether client is joined on the channel already
3873 in JOIN command. Affected file lib/silcclient/command.c.
3875 * Fixed the JOIN command reply to check whether the channel
3876 already exists. Affected file lib/silcclient/command_reply.c.
3878 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3880 * Added silc_ske_status_string to map the SKE error numbers
3881 to readable strings. The affected files are
3882 lib/silcske/silcske[_status].[ch].
3884 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3886 * Do not show the private channels on the WHOIS channel list
3887 as it is not allowed by the protocol. The affected file is
3890 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3892 * Assure that the packet length digged from the actual packet
3893 is something sensible in the silc_packet_decrypt_rest_special
3894 in lib/silccrypt/silcpacket.c.
3896 * Free and NULL the allocated pointer in silc_hmac_alloc if
3897 the HMAC allocation fails. The affected file is
3898 lib/silccrypt/silchmac.c.
3900 * Print the selected security properties to the log files in
3901 the server. Affected file silcd/protocol.c.
3903 * Add SKE's reference counter even if calling the completion
3904 callback manually. Otherwise it goes negative, although it
3905 does not cause any problems. The affected file is
3906 lib/silcske/silcske.c.
3908 * Remove the client entry with short timeout after giving the
3909 KILL command. Affected file lib/silcclient/command.c.
3911 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3912 case all found clients are already disconnected (WHOWAS would
3913 found them) in the server. Affected file silcd/command.c.
3915 * Update the last_receive (time of last data received) to be
3916 updated only when received private or channel message so that
3917 the idle time showed in WHOIS makes more sense.
3919 * Added boolean field `valid' in to the SilcClientEntry in the
3920 client library to indicate whether the entry is valid or not.
3921 This fixes the nickname change bug on channel when changing
3922 the nickname to be same than the old (like nick to Nick) the
3923 nickname formatter doesn't set the new nick anymore to Nick@host.
3924 Affected file lib/silcclient/idlist.[ch].
3926 * Now actually fixed the nickname changing on disconnection.
3927 Added new function silc_change_nick to the Irssi SILC Client.
3928 Affected file irssi/src/silc/core/client_ops.c,
3929 irssi/src/silc/core/silc-nicklist.[ch].
3931 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3933 * Check that the public key exists in the GETKEY command before
3934 trying to encode it. Affected file silcd/command.c.
3936 * Print some notifications on received public keys with GETKEY
3937 command in the Irssi SILC Client. Affected files are
3938 irssi/src/fe-common/silc/module-formats.[ch],
3939 irssi/src/silc/core/client_ops.c.
3941 * Use IDENTIFY command to resolve the server information in the
3942 GETKEY command instead of INFO command. Affected file
3943 lib/silcclient/command.c.
3945 * All command reply functions in the client library now calls
3946 the pending command reply callbacks even if an error has
3947 occurred. The server has done this a long time and now it was
3948 time to move the client library to this as well. Now all
3949 errors can be delivered back to the pending command reply
3950 callbacks if necessary. Affected files are
3951 lib/silcclient/command[_reply].[ch].
3953 * Change the nickname on disconnection back to the username
3954 because in reconnect the server will enforce it to it anyway.
3955 Affected file irssi/src/silc/core/silc-servers.c.
3957 * Fixed a config file parsing bug in the Irssi SILC client.
3958 Affected file irssi/src/silc/core/clientconfig.c.
3960 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3962 * When printing the channel mode on JOIN, verify that the
3963 channel key and channel's HMAC are valid. Affected file
3964 irssi/src/silc/core/client_ops.c.
3966 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3968 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3969 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3970 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3972 * Removed channel key rekey task deleting from the function
3973 silc_server_save_channel_key. Affected file silcd/server.c.
3974 Added explicit timeout task context instead that is used to
3975 delete the task if we are registering a new task before the
3976 new task has elapsed.
3978 * When channel key rekey occurs the client library now saves
3979 the old channel key for a short period of time (10 seconds) and
3980 is able to use it in case some is still sending channel
3981 messages encrypted with the old key after the rekey. Affected
3982 file lib/silcclient/[idlist.h|client_channel.c].
3984 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3986 * Added check to the silc_server_new_id_real to not accept
3987 new ID if it is the sender's own ID. Affected file is
3988 silcd/packet_receive.c.
3990 * Assure that we do not announce ourself or the one we've
3991 sending our announcements when we're router and are announcing
3992 servers to our primary router. Affected file silcd/server.c.
3994 * Fixed silc_server_command_identify_check_client to assemble
3995 correct WHOIS packet. It send corrupted WHOIS packet and
3996 caused problem with router to router connections. Affected
3997 file silcd/command.c.
3999 Fixed also silc_server_command_whois_check the same way
4000 as for the IDENTIFY command.
4002 * Added new SilcIDListStatus to the server in the SilcIDListData
4003 structure. The status now includes the current status of
4004 the entry (like registered, resolved etc.). Affected file
4005 silcd/idlist.[ch]. Defined a bunch of different status types
4006 as well. This replaced the old boolean registered field as well.
4008 Added resolve_cmd_ident field to the SilcClientEntry structure
4009 too so that if the entry is for example being resolved so
4010 another command may attach to the same pending command reply
4011 without requiring to resolve the same entry again. This concept
4012 should optimize the WHOIS and the IDENTIFY resolving under
4013 heavy load by taking away unnecessary resolving for entries
4014 that are being resolved already.
4016 Added support for adding multiple pending commands for one
4017 command idenfier. Affected file silcd/command[_reply].[ch].
4019 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4020 before deleting the data. Otherwise the hash table will have
4021 freed data in comparison functions. Affected file is
4022 silcd/command_reply.c.
4024 * Fixed silc_idlist_replace_client_id to add the new entry to
4025 the cache with NULL nickname. Otherwise there will be invalid
4026 memory as the nickname after the nickname is freed. Affected
4027 file silcd/packet_receive.c.
4029 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4030 saved into wrong slots because the previous number of entries
4031 was not taken into account. Affected file silcd/idlist.c.
4032 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4034 * If we are router and we receive JOIN notify to a channel that
4035 does not have any users then notified client is marked as the
4036 channel founder, as it is it. The affected file is
4037 silcd/packet_receive.c
4039 * Added to the extended hash table API's table_del_*ext functions
4040 the destructor as argument too, so that the caller can decide
4041 which destructor to use or whether to use destructor at all.
4042 Affected file lib/silcutil/silchashtable.[ch].
4044 * Fixed ID Cache purging. It actually deleted the entries from
4045 the hash table after the data was freed. The hash table ended
4046 up comparing freed memory. The affected file is
4047 lib/silccore/silcidcache.c.
4049 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4051 * Fixed Irssi SILC client's KILL command's HELP syntax.
4053 * The USERS command now resolves the detailed user information
4054 if the userinfo field is missing. Affected file is
4055 lib/silcclient/command_reply.c.
4057 * Do not print error in silc_file_read if the read file does
4058 not exist. Just silently return NULL. Affected file is
4059 lib/silcutil/silcutil.c.
4061 * Fixed the silc_log_output to not wine about NULL filename
4062 and to not create some bogus " " filename. Affected file is
4063 lib/silcutil/silclog.c.
4065 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4067 * Fixed various printing bugs on the user interface in the
4068 Irssi SILC Client. Minor changes that were forgotten from
4071 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4073 * Fixed the configure.in.pre and the compilation and distribution
4074 environment to support the new autoconf 2.52. That version is
4075 now required to compile the CVS trunk.
4077 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4079 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4080 to generally parse user@fqdn format strings. Affected file
4081 lib/silcutil/silcutil.c.
4083 * Added nickname_format and nickname_force_format fields to the
4084 SilcClientParams structure. The first one defines the format
4085 for the nicknames that the library will enforce if the receives
4086 multiple same nicknames. The second one is boolean value and
4087 can be used to force the library to always enforce the format
4088 to the nicknames regardles whether there are multiple nicknames
4089 or not. This configurable formatting was employed to flexibly
4090 support accessing multiple nicknames from the user interface.
4091 The userinterface can now set the nicknames to what ever format
4092 they prefer. Affected file lib/silcclient/silcapi.h.
4094 Added function silc_client_nickname_format to the file
4095 lib/silcclient/idlist.c. It performs the nickname formatting.
4097 Added new field `hostname´ to the SilcClientEntry context.
4098 It holds the hostname of the client. Affected file is
4099 lib/silcclient/idlist.h.
4101 * Irssi SILC Client sets the nicknames in nick@hostn format.
4102 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4103 irssi/src/silc/core/silc-core.c.
4105 The WHOIS printing now also shows both the real nickname and
4106 the formatted nickname so that user knows how to access the
4107 user if there are multiple same nicknames cached. Affected
4108 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4109 printing formatting too to take the hostname now as a separate
4110 argument. The Affected file is
4111 irssi/src/fe-common/silc/modules-formats.[ch].
4113 * Changed the silc_client_get_clients_local to accept the formatted
4114 nickname as argument. It accepts the real nickname too but the
4115 formatted nickname can be used to find the true entry from
4116 multiple entries. Affected file lib/silcclient/silcapi.h and
4117 lib/silcclient/idlist.c.
4119 * Added nickname_format_parse field to the SilcClientParams.
4120 It is a callback function provided by the application to parse
4121 the nickname out of the formatted nickname string. The library
4122 calls it to get the nickname from the formatted string. Since
4123 the application generally knows better the format of the nickname
4124 string it parses it instead of the library, even though library
4125 encodes the formatted string. If the callback function is not
4126 provided then the library will use the string as is. The
4127 affected file is lib/silcclient/silcapi.h.
4129 * All the nickname strings passed to the client library in
4130 commands are now expected to be formatted nickname strings.
4131 If the command does not support the formatted nickname string
4132 it will assume that the sent string is the actual nickname.
4133 Affected file lib/silcclient/command.c.
4135 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4137 * Added public key authentication support to OPER and SILCOPER
4138 commands in the client library. Affected file is
4139 lib/silcclient/command.c.
4141 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4143 * Changed the get_auth_methdod client operation to be asynchronous.
4144 It can be async if the application resolves the authentication
4145 method from the server during the negotiation. Added new
4146 SilcGetAuthMeth completion callback that the application will
4147 call after resolving the authentication method.
4149 Added function silc_client_request_authentication_method that
4150 the application can use to resolve the authentication method
4151 from the server. Added also SilcConnectionAuthRequest callback
4152 that the library will call after the server has replied. The
4153 application can call this function if it does not know the
4154 current authentication method.
4156 Affected files are lib/silcclient/client.c and
4157 lib/silcclient/silcapi.h.
4159 * The Irssi SILC client now automatically resolves the authentication
4160 method incase any configuration information is not present (and
4161 currently there never is). The affected file is
4162 irssi/src/silc/core/client_ops.c.
4164 * Fixed public key authentication from the client library.
4165 Affected file lib/silcclient/protocol.c. Changed also the
4166 protocol specification about the public key authentication in
4167 the connection authentication protocol. The actual data to be
4168 signed is now computed with a hash function before signing.
4170 * Fixed the public key authentication from the server as well.
4171 Affected file silcd/protocol.c.
4173 * Removed the mlock()'s from the memory allocation routines.
4174 Affected file lib/silcutil/silcmemory.c. The ./configure does
4175 not check anymore for the mlock(). Affected file is
4178 * Fixed USERS command in server to allow the execution of the
4179 command for private and secret channels if the client sending
4180 the command is on the channel. Affected file silcd/command.c.
4182 * Fixed silc_client_get_clients_local to return the clients
4183 count correctly. It could return wrong value. Affected file
4184 lib/silcclient/idlist.c.
4186 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4188 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4189 types. The assembler optimizations seemed not to like 64-bit
4190 data types. The assmebler optimizations thus are now enabled
4191 also for BSD systems as opposed to only enable them for Linux.
4193 * Do not check for threads at all on BSD systems. Affected
4194 file configure.in.pre.
4196 * Removed -n and -h options from the Irssi SILC Client since
4197 they are not used in silc.
4199 * Fixed the prime generation to assure that the first digit
4200 of the generated random number is not zero since our conversion
4201 routines does not like number strings that starts with zero
4202 digit. If zero digit is seen the random number is regenerated.
4203 This caused some corrupted RSA keys when the zero first digit
4204 was met. Affected file lib/silcmath/silcprimegen.c.
4206 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4208 * Fixed WIN32 configuration in the ./configure script.
4209 Fixed to include xti.h on environments that has it.
4210 Patches by Carsten Ilchmann and andrew.
4212 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4214 * Changed the silc_id_create_client_id to be collision
4215 resistant. It is now assured that there cannot be created
4216 two same client ID's. I suspect that some weird bugs in
4217 the server were actually caused by duplicate Client IDs.
4218 Affected file silcd/serverid.[ch]. A router receiving
4219 new ID now also assures and informs the sending server
4220 if the ID caused collision.
4222 * Changed the silc_id_create_channel_id to also assure that
4223 there are no collisions.
4225 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4227 * Statement about ignoring the Mutual Authentication flag when
4228 performing rekey with PFS was a bit misleading. It is ignored
4229 if it was set in the initial negotiation, it cannot be even
4230 set in the rekey. Fixed in the ke-auth draft. Started the
4231 new versions of the protocol drafts in the doc/.
4233 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4235 * Fixed a bug in silc_client_command_identify_save when saving
4236 new channel information. The channel name was no duplicated
4237 and caused crash on exit. Affected file is
4238 lib/silcclient/command_reply.c.
4240 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4242 * Fixed the getkey command handling in the server. Send just
4243 empty OK reply to the sender if the key could not be fetched
4244 (but everything else was ok, like the key just was not available).
4245 Changed the public key parameter to optional in the protocol
4246 specs so that empty OK reply can be sent. Affected file
4249 Added a message to Irssi SILC client to tell to user if the
4250 server did not return a public key.
4252 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4254 * Fixed a channel key regeneration bug. It registered new
4255 timeout tasks exponentially until all system resources were
4256 used. Affected file silcd/server.c.
4258 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4260 * Added the SILC Document generator to the scripts/silcdoc.
4261 It can be used to generate the Toolkit Reference Manual out
4262 of the source tree. Internally it will also use the RoboDoc
4263 generator now imported in util/robodoc.
4265 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4267 * Added couple of return's in rekey protocol if error orccurred
4268 during the protocol. The execution must be terminated.
4269 Affected file silcd/protocol.c. Also, terminate the protocol
4270 always with timeout.
4272 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4274 * The client's Client ID was created initally from the wrong
4275 nickname (it could have been in format nick@host) in the
4276 silc_server_new_client. Affected file silcd/packet_receive.c
4278 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4280 * Added some SILC_LOG_ERROR's to various error conditions
4281 if client could not be added to ID cache. Affected files
4282 silcd/packet_receive.c and silcd/server.c.
4284 * When client's sock->user_data is freed, NULL also the
4285 client->router and client->connection pointers. Added check
4286 for these pointers being NULL to various places around the
4287 code. Affected file silcd/server.c.
4289 * Added client->data.registered == TRUE checks to various
4290 places around the code to assure that unregistered client's
4291 are not handled when it is not allowed. Affected file
4294 * Added `bool registered' fields to all
4295 silc_idlist_[server|client]_get_* routines to indicate whether
4296 the fetched client needs to be registered or not. Affected
4297 file silcd/idlist.[ch].
4299 * Add your own entry as registered to the ID cache in the
4300 server. Affected file server.c.
4302 * Fixed a bug in silc_server_new_server. The SilcServer was
4303 set as the new server's context instead of SilcServerEntry.
4304 This naturally caused some weird bugs.
4306 * Added "updated" field the SilcChannelEntry which indicates
4307 the time since the channel entry was last accessed. This
4308 can be used to determine whether it is necessary to
4309 announce the channel after backup resuming protocol.
4310 Affected files silcd/idlist.[ch].
4312 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4314 * Do not delete the channel rekey task when adding it
4315 for in silc_server_create_channel_key.
4317 * Changed the silc_server_create_channel_key to return
4318 TRUE or FALSE to indicate the success of the channel key
4321 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4323 * Fixed MSVC++ project files and added missing files to
4324 Makefiles under win32/.
4326 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4328 * Do not add TCP_NODELAY flag if the operating system
4329 does not have it defined. Affected files are
4330 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4332 * Fixed buffer overflow from Irssi SILC Client. Affected
4333 file irssi/src/fe-common/core/themes.c.
4335 * Fixed double free in client library in the file
4336 lib/silcclient/client.c when disconnecting from server.
4338 * Applied double free patch from cras to Irssi SILC client.
4339 Affected files irssi/src/core/[modules/expandos].c
4341 * Fixed the disconnection handling to Irssi SILC Client.
4342 The application must call silc_client_close_connection
4343 in ops->connect client operation in case of failure of
4344 the connection. Affected file is
4345 irssi/src/silc/core/client_ops.c.
4347 * Do not set sock->protocol to NULL in the function
4348 silc_client_close_connection after executing the protocol's
4349 final callback since the sock might not be valid anymore.
4350 Affected file lib/silcclient/client.c.
4352 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4354 * Do not enable SILC_THREADS if the linking with libpthread
4355 did not happen. Affected file configure.in.pre.
4357 * Added notion to protocol specification that server must
4358 verify the sent authentication payload with CMODE when
4359 setting the channel founder key. Implemented it to the
4360 server. Affected file silcd/command.c.
4362 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4364 * Added _EXTRA_DIST SILC distribution variable to the
4365 distributions file. It is used to conditionally add extra
4366 files or directories to the specific distribution. Affected
4367 files ./prepare, Makefile.am.pre and distributions.
4369 Removed the `_' from the start of the distribution names.
4372 * Added README.WIN32 for instructions to compile the Toolkit
4375 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4377 * Fixed a double free in disconnection in the server. Affected
4378 file is silcd/server.c.
4380 * Fixed the lib/silcske/groups.c to work now also with GMP
4381 MP library. The string conversion did not work when using
4382 specific base and the base is indicated in the string as well.
4384 * Created win32/ directory which now includes MSVC++ specific
4385 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4386 It will appear only in the toolkit distribution
4388 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4390 * Changed the key material distribution function in case when
4391 the hash output is too short. The data is now concatenated
4392 a bit differently than it used to. Made the change to the
4393 SKE protocol specification.
4395 * Added better GMP detection to configure.in.pre. A patch
4398 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4400 * Fixed a minor bug in SKE that might cause some problem on
4401 some platforms. Affected file lib/silcske/silcske.c.
4403 * Added the cookie checking for initiator in the SKE. It checks
4404 that the responder returns the sent cookie unmodified. The
4405 affected file is lib/silcske/silcske.c. Added new SKE
4406 error type INVALID_COOKIE that can be sent during the
4407 negotiation. Fixed some memory leaks as well.
4409 * Added the "invalid cookie" error message to Irssi SILC client's
4412 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4414 * Added `task_max' field to the SilcClientParams to indicate
4415 the maximum tasks the scheduler can handle. If set to zero,
4416 default values are used. Affected file lib/silcclient/silcapi.h.
4418 * Fixed memory leaks in silc_client_close_connection. Affected
4419 file lib/silcclient/client.c.
4421 * Added silc_client_del_client_entry to client library to free
4422 all memory of given client entry. Affected file is
4423 lib/silcclient/idlist.[ch].
4425 * Added new functions silc_client_del_channel and
4426 silc_client_del_server to delete channel and server entries.
4427 Affected file lib/silcclient/[silcapi.h/idlist.c].
4429 * Removed silc_client_del_client_by_id from silcapi.h.
4431 * Fixed the INFO command to return the server's own info
4432 correctly when querying by Server ID. Affected file is
4435 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4437 * Removed the non-blocking settings in WIN32 code in the
4438 silc_sock_[read/write] and added SleepEx instead. Affected
4439 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4440 of input data is now checked with FIONREAD and ioctlsocket.
4442 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4444 * Call silc_schedule_task_del_by_context in the
4445 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4446 Affected file lib/silccore/silcprotocol.c.
4448 * Call silc_protocol_cancel for active protocols in the
4449 silc_server_close_connection if the funtion
4450 silc_server_free_sock_user_data has not been called.
4451 Affected file silcd/server.c.
4453 * Generic tasks cannot be deleted using the del_by_fd
4454 task deleting function since generic tasks does not match
4455 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4457 * Added a notion to SILCOPER help file that the SILCOPER works
4458 only on router server, not on normal server.
4460 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4462 * Added for WIN32 support for the new scheduler as well.
4463 Affected file lib/silcutil/win32/silcwin32schedule.c.
4465 * Fixed the SHA1 implementation to work on various platforms.
4467 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4469 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4470 API. It is part of the scheduler now. Everything else is
4471 as previously but some functions has changed their names.
4472 Checkout the lib/silcutil/silcschedule.h for the interface.
4473 Updated all applications to use the new interface. Affected
4474 files are lib/silcutil/silcschedule.[ch].
4476 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4478 * Found a bug in the SKE implementation. The HASH value,
4479 specified by the protocol, was not computed correctly. The
4480 public key of the responder was not added to the computation
4481 even though it is mandatory. Affected file lib/silcske/silcske.c.
4482 This unfortunately causes incompatibilities with older
4483 clients and servers.
4485 * Added WIN32 specific network init and uninit functions:
4486 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4487 the Winsock2. Affected file lib/silcutil/silcnet.h and
4488 lib/silcutil/win32/silcwin32net.c.
4490 * Set the socket always to nonblocking mode on WIN32 after
4491 reading data or writing data. Affected file is
4492 lib/silcutil/win32/silcwin32sockconn.c.
4494 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4496 * Fixed various compilation problems under WIN32. Affected
4497 files lib/silcutil/win32/silcwin32thread.c and
4498 lib/silcutil/win32/silcwin32schedule.c.
4500 * Removed all _internal.h #includes from public header
4501 files. Internal headers must never be included from
4504 Removed also the lib/silcske/payload_internal.h file.
4506 * All include files that may be needed (public and some others
4507 included by the public headers) by application developers are
4508 now copied to the ./includes directory. It does not copy any
4509 internal headers. Affected file Makefile.defines.pre and all
4510 Makefile.am's under lib/ and subdirs.
4512 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4514 * Do not change the ~/.silc directory's permissions automatically.
4515 Affected file irssi/src/silc/core/clientutil.c.
4517 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4519 * Do not cancel the protocol in silc_server_close_connection
4520 it might cause recursion. Now cancelled in the function
4521 silc_server_free_sock_user_data. Affected file silcd/server.c.
4523 * Fixed the silc_server_remove_clients_by_server to regenerate
4524 the channel keys correctly finally. Added also new function
4525 silc_server_remove_clients_channels to actually do it.
4526 Affected file silcd/server.c.
4528 * Fixed the silc_server_new_channel to not crash by giving
4529 wrong router to the new channel. Affected file is
4530 silcd/packet_receive.c.
4532 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4534 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4535 which is given as argument to the silc_client_alloc now.
4536 It can be used to configure the client and set various parameters
4537 that affect the function of the client.
4539 * The USERS command in server did not check whether the channel
4540 is private or secret. Affected file silcd/command.c.
4542 * Added new argument to the USERS command in protocol specification.
4543 The USERS command now can take the channel name as argument
4544 as well. Added support for this in client and server and
4545 updated the protocol specs.
4547 * Completed the GETKEY command in client. It can be now used
4548 to fetch also servers public key not only some clients.
4549 Affected files lib/silcclient/command[_reply].c.
4551 * Added silc_client_get_server to return server entry by the
4552 server name. Affected files lib/silcclient/silcapi.h and
4555 * Redefined the IDENTIFY command in protocol specification to be
4556 more generic. It now can be used to query information about
4557 any entity in the SILC Network, including clients, servers and
4558 channels. The query may be based either the entity's name
4559 or the ID. Added support for this in both client and server.
4561 Affected files silcd/command.c and lib/silcclient/command.c
4562 and command_reply.c.
4564 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4565 the _from_client and _from_server functions. Affected file
4568 * Added silc_client_get_channel_by_id_resolve to the file
4569 lib/silcclient/silcapi.h to resolve channel information by
4570 its ID. Added also silc_client_get_channel_by_id that
4571 does not resolve it from the server.
4573 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4575 * Added SilcServerEntry context into the client library
4576 to represent one server. The INFO command now allocates
4577 these to save the resolved server info. For now on the
4578 client library will also keep information about servers,
4579 connected and resolved with INFO.
4581 The INFO command now allocates the SilcServerEntry context
4582 and saves the server info there. The COMMAND_REPLY in
4583 the INFO now returns the parameters to application in
4584 same order as defined in the protocol specification.
4586 The entries are cached in the client->server_cache.
4588 * The INFO command is now issued after received the Client ID
4589 from the server. Affected file lib/silcclient/client.c.
4591 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4592 to the application as the mode changer might be server.
4593 It is guaranteed that NULL is not returned anymore to the
4594 application. Affected file lib/silcclient/client_notify.c.
4596 The ID Type is now also passed to the application so that
4597 it can check whether the returned entry is SilcClientEntry
4600 Added new function silc_client_get_server_by_id to return
4601 the server entry by ID. Affected files are the
4602 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4604 * Do not create the channel in the Irssi SILC Client when issuing
4605 the JOIN command but when received the sucessful JOIN command
4606 reply. Otherwise the channel might get created even though we
4607 could not join it. The Affected file is
4608 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4610 * Fixed a channel joining bug in router. The router must also
4611 check the channel modes, invite and ban lists etc. when serving
4612 the JOIN command sent by normal server. Affected file is
4613 silcd/command.c. The router now resolves the client's
4614 information from the server who sent the JOIN command if it
4615 does not know it, and processes the JOIN command only after
4618 * Changed the SilcCommandCb to take new argument; void *context2.
4619 Affected file lib/silccore/silccommand.h
4621 The second argument in the command callbacks in the server now
4622 includes the SilcServerCommandReplyContext if the command was
4623 called as pending command callback from the command reply.
4624 Otherwise it is NULL. When called as pending the status of the
4625 command reply will be checked and if it was erronous the
4626 error will be sent to the original sender of the command.
4627 This way the client always receives the error messages even
4628 though the server was actually the one who received the error
4629 when it resent the command to router, for example. Affected
4630 files silcd/command[_reply].[ch].
4632 * Fixed sending WHOWAS command's error message to client if
4633 the requested client could not be found. It was missing.
4636 * Changed the CMODE and CUMODE commands reply arguments in the
4637 protocol specification. The Channel ID is now sent in both
4638 of the commands to identify the channel. Implemented this
4639 new feature to the client and server. Affected files
4640 lib/silcclient/command_reply.c and silcd/command.c.
4642 * Made better checks for invite and ban lists in the JOIN
4643 command in server. Affected file silcd/command.c.
4645 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4647 * The server now performs the incoming host IP/DNS lookup
4648 using the silc_socket_host_lookup and thus does not block
4649 the server anymore. Affected file silcd/server.c.
4651 * Completed the multi-thread support for SILC Scheduler in
4652 the lib/silcutil/silcschedule.c.
4654 * Fixed the configure.in.pre to detect the pthread correctly
4657 * Fixed a deadlock in silc_task_queue_wakeup in the file
4658 lib/silcutil/silctask.c.
4660 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4662 * Added new function silc_schedule_wakeup that is used in
4663 multi-threaded environment to wakeup the main thread's
4664 schduler. It needs to be used when a thread adds a new task
4665 or removes a task from task queues. After waking up, the
4666 scheduler will detect the task queue changes. If threads
4667 support is not compiled in this function has no effect.
4668 Implemented the wakeup mechanism to both Unix and WIN32
4669 systems. Affected files are lib/silcutil/silcschedule.[ch],
4670 lib/silcutil/unix/silcunixschedule.c and the
4671 lib/silcutil/win32/silcwin32schedule.c.
4673 * Added new function silc_task_queue_wakeup to wakeup the
4674 scheduler by the specified task queue. Affected file
4675 lib/silcutil/silctask.[ch].
4677 * The silc_socket_host_lookup_start now wakes up the scheduler
4678 after adding the timeout task. Affected file is
4679 lib/silcutil/silcsockconn.c.
4681 * The silc_socket_host_lookup is synchronous now if the threads
4682 support is not compiled in. However, the callback is still
4683 called asyncronously through the scheduler, anyway. Affected
4684 file lib/silcutil/silcsockconn.c.
4686 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4688 * Added new function silc_socket_host_lookup to perform
4689 asynchronous IP and FQDN lookups for the socket connection.
4690 Affected files lib/silcutil/silcsockconn.[ch].
4692 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4694 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4695 that may or may not compile the mutex support in.
4697 Changed the silc_mutex_alloc interface. It allocates the
4698 mutex now to the sent pointer and returns TRUE or FALSE.
4700 Affected file lib/silcutil/silcmutex.h.
4702 * Wrote the SILC Task Queue interface to support multi-threads.
4703 Affected file lib/silcutil/silctask.[ch].
4705 * Wrote the SILC Scheduler to support multi-threads. Affected
4706 file lib/silcutil/silcschedule.c.
4708 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4710 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4711 in lib/silcutil/win32/.
4713 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4715 * Defined SILC Mutex API and SILC Thread API and implemented
4716 them for Unix. Affected files are
4717 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4718 lib/silcutil/unix/silcunixmutex.c and
4719 lib/silcutil/unix/silcunixthread.c.
4721 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4723 * Fixed the silc_server_remove_clients_by_server's channel
4724 key re-generation. The hash table handling was incorrect
4725 and would not work with many channels. Affected file is
4728 * Fixed some memory leaks around the server code.
4730 * Rewrote the silc_server_get_users_on_channel to support IPv6
4731 based Client ID's. Affected file silcd/server.c.
4733 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4734 specification. However, a separate document must be written
4735 to define the detailed signing procedure and the payload
4736 associated with the flag. Defined the flag to the
4737 lib/silccore/silcchannel.h as well.
4739 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4741 * Changed the dynamic tables to static size tables in the
4742 lib/silccrypt/silchmac.c.
4744 * Removed GCC dependencies from the code. A patch by cras.
4746 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4748 * Do not show the error "Error receiving packet bla bla"
4749 in server if it really was not an error (-2 means that reading
4750 is pending). Affected file silcd/server.c.
4752 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4754 * Fixed a possible crash in silc_server_remove_clients_by_server
4755 in silcd/server.c. Fixed there also some memory leaks.
4757 * Fixed the silc_idlist_replace_client_id. It could replace
4758 wrong key in the hash table. Affected file silcd/idlist.c.
4760 * Do not check whether there are global users on the channel
4761 if the channel->global_users is FALSE. Affected functions
4762 silc_server_remove_from_one_channel and
4763 silc_server_remove_from_channels in silcd/server.c. Also,
4764 do not check if the removed client is local as we can be
4765 sure that global client was not removed from the channel
4766 and checking for global users is not needed.
4768 * The silc_server_remove_clients_by_server now re-generates
4769 the channel keys correctly for those channels that had
4770 clients removed from them. Affected file silcd/server.c.
4772 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4774 * Found the reason of random crashes in the server. We weren't
4775 ignoring the SIGPIPE signal (which can be sent in write())
4776 and it crashed the server. Affected file silcd/silcd.c.
4778 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4780 * Assure that sock->user_data is not NULL in the function
4781 silc_server_packet_send in silcd/packet_send.c.
4783 * Disconnect the remote connection if it could not be added
4784 to any ID lists in the server. The affected file is
4787 * Check in silc_server_packet_send[_real/dest] that the
4788 socket is not disconnecting and ignore the data if it is.
4789 Affected file silcd/packet_send.c.
4791 * Define inline to __inline on native WIN32 compilation.
4792 Affected file includes/silcwin32.h.
4794 * Added some explicit type casts for inline code since MSVC
4795 require them. Affected files lib/silcutil/silcbuffer.h,
4796 lib/trq/silcdlist.h and lib/trq/silclist.h.
4798 * Print warning in log files from now on if the packet
4799 decryption fails. Affected file silcd/server.c.
4801 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4803 * Changed the `say' client operation's interface to accept
4804 new `type' argument to indicate the type of the message sent
4805 by the library. The application may filter the library's
4806 messages according the type. The affected file is the
4807 lib/silcclient/silcapi.h.
4809 * Added two new functions to lib/silcclient/silcapi.h:
4810 silc_client_del_client and silc_client_del_client_by_id.
4811 Affected file lib/silcclient/idlist.c.
4813 * Moved the clientincludes.h from includes/ to silc/ and
4814 serverincludes.h from includes/ to silcd/.
4816 * The modes for the CMODE and CUMODE are now passed as
4817 uint32 for application with COMMAND_REPLY. The affected
4818 file is lib/silcclient/command_reply.c.
4820 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4822 * /WHOIS without arguments shows client's own information.
4823 Affected file lib/silcclient/command.c.
4825 * Changed PING to not accept any arguments. The specs
4826 says that client can ping only the connected server so
4827 requiring an argument is not needed. Affected file is
4828 lib/silcclient/command.c.
4830 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4832 * Fixed a fatal bug in private message sending and reception
4833 encryption and decryption when using private message keys.
4834 The implementation was incorrect and did not follow the
4835 specification. It causd that some of the message were
4836 lost since it did not use the sending and receiving keys
4837 as the protocol suggests. This has been fixed and will cause
4838 incompatibilities with older clients when sending private
4839 message encrypted with private message keys. Affected files
4840 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4841 and various other in Irssi SILC Client.
4843 Added `responder' boolean argument to the functions
4844 silc_client_add_private_message_key[_ske] to indicate when
4845 the key is added as responder or initiator of the key
4848 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4850 * Removed the silc_ske_check_version function and created
4851 a SilcSKECheckVersion callback. Added also a function
4852 silc_ske_set_callbacks that is now used to set all SKE
4853 callbacks. The callback functions are not given to
4854 the SKE functions anymore, but this function is used to
4857 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4859 * Added `silc_version' argument to the silc_client_alloc
4860 to define the version of the application for the library.
4861 The library will use the version string to compare it
4862 against the remote host's (usually a server) version
4863 string. Affected file lib/silcclient/silcapi.h
4865 * Added the KE protocol context to Key Agreement context
4866 in client library so that we can abort the SKE if it
4867 is in process when we get timeout. Affected file is
4868 lib/silcclient/client_keyagr.c.
4870 * Do not resolve the client ID forever if it returns in the
4871 first time that such client does not exist. This was done
4872 for example with private message. Affected file is
4873 lib/silcclient/client_prvmsg.c.
4875 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4877 * Do not add regex.h for WIN32. The affected file
4878 includes/silcincludes.h.
4880 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4881 not work yet 100%. It generates the DLL's automatically
4882 when compiling with --with-win32 under cygwin.
4884 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4886 * lib/contrib/regex.c is not compiled on WIN32.
4888 * Added silc_net_get_socket_opt function to the
4889 lib/silcutil/silcnet.h.
4891 * Added includes/silcwin32.h for WIN32 specific includes
4894 * Do not use ptime structure or any of the posix process
4895 functions on WIN32 in lib/silccrypt/silrng.c.
4897 * Added silc_gettimeofday to provide generic function
4898 for struct timeval on all platforms. Added the function
4899 to lib/silcutil/silcutil.h.
4901 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4903 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4904 library as they clearly belong there. As a plus side we
4905 can make the actual socket connection routines platform
4908 Added also new generic function silc_socket_read and
4909 silc_socket_write (that used to be silc_packet_[read/write].
4910 The implementation of these are platform specific.
4912 * Added WIN32 specific routines of silc_socket_[read/write]
4913 to lib/silcutil/win32/silcwin32sockconn.c.
4915 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4917 * Added preliminary support for native WIN32 compilation under
4918 cygwin (using the -mno-cygwin option for GCC) to the
4919 ./configure.in.pre. The --with-win32 now prepares the
4920 compilation for native WIN32.
4922 * Rewrote the SILC Scheduler interface in the file
4923 lib/silcutil/silcschedule.h. The scheduler is now context
4924 based and does not have anymore any global static scheduler.
4925 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4926 and created lib/silcutil/win32 directory for WIN32 based
4929 * Added Unix specific network routines to the
4930 lib/silcutil/unix/silcunixnet.c and the old
4931 lib/silcutil/silcnet.c includes now only generic routines.
4933 Added WIN32 specific network routines to the
4934 lib/silcutil/win32/silcwin32net.c.
4936 * Added Unix specific utility functions from the
4937 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4939 * Added WIN32 SILC Scheduler to the file
4940 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4943 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4945 * Do not handle JOIN notify in the server if the target client
4946 is not registered (idata->registered == FALSE). The affected
4947 file is silcd/packet_receive.c.
4949 * Update the nickrec->founder in event_cumode in the Irssi SILC
4950 client. Affected file irssi/src/silc/core/silc-channels.c.
4952 * Fixed the CUMODE_CHANGE notify handling in the server when
4953 server and router are announcing their clients on channels.
4954 Now the mode changes are saved and notified correctly. The
4955 affected file is /silcd/packet_receive.c.
4957 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4958 They really did not replace the cache entry in the ID Cache.
4959 Now they do that. Affected file silcd/idlist.c.
4961 * Fixed the KICK notify handling in the Irssi SILC client to
4962 update the channel records so that the kicked client does not
4963 appear to be on the channel. The affected file is
4964 irssi/src/silc/core/silc-channels.c.
4966 * Always update the conn->current_channel when executing command
4967 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4969 * Fixed the KILL notify handling in Irssi SILC client to remove
4970 the killed client on all channels.
4972 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4974 * Fixed the silc_parse_command_line to remove extra spaces
4975 from the start and end of the arguments. Affected file is
4976 lib/silcutil/silcutil.c.
4978 * Cancel and free any active protocol in the function
4979 silc_server_close_connection. Affected file silcd/server.c.
4981 * Cancel and free any active protocol in the function
4982 silc_client_close_connction. Affected file is
4983 lib/silcclient/client.c.
4985 * Do not execute the KILL command for clients that are in
4986 history (ie. they are not in the network). Affected file is
4989 * Fixed KILL notify handling, client does not crash anymore.
4990 Affected file irssi/src/silc/core/silc-channels.c.
4992 * Reduced the default packet buffer size from 2048 to 1024 in
4993 lib/silccore/silcpacket.c.
4995 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4996 counter to the SKE context that is incresed when the SKE library
4997 performs async operation outside the library. If the outside
4998 process frees the SKE context and FREED status will be set
4999 and the library will detect after the sync operation that the
5000 libary is freed. The affected files are
5001 lib/silcske/silcske[_status].[ch].
5003 * Resolve the client entry information in the function
5004 silc_client_channel_message to assure that NULL pointer is not
5005 passed as client entry to the application. */
5007 * Fixed the task timeout calculation to assure that there is
5008 never negative timeouts. The affected file is
5009 lib/silcutil/silcschedule.c.
5011 * Fixed the channel user mode notification sending in server.
5012 It was sent point-to-point to the router (or to server by router)
5013 but it needs to be destined to a channel. The routines now
5014 supports sending the channel user mode notifys to the channels
5015 when announcing clients and channels. Affected files are
5016 silcd/server.c and silcd/packet_receive.c.
5018 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5019 It did not actually replace the old channel entry in the cache.
5020 Affected file lib/silcclient/client_notify.c.
5022 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5024 * Fixed a possible crash in silc_packet_send_prepare. It now
5025 assures always that there is enough space in the buffer and
5026 at the tail area of the buffer (for MAC).
5028 Fixed the inbound buffer reallocation in silc_packet_read.
5029 It was old code and did not handle the reallocation correctly.
5032 The affected file is lib/silccore/silcpacket.c.
5034 * Fixed buffer overflow in silc_parse_nickname in the file
5035 lib/silcutil/silcutil.c.
5037 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5039 * make install generates new server keys only if there is not
5042 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5044 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5045 Added check that if the NOREPLY is set then we will not send
5046 the away message. This avoids infinite loop of away messages
5047 if both clients are away. The affected file is
5048 lib/silcclient/client_prvmsg.c.
5050 * Fixed client crash if /NICK was given without arguments.
5051 Affected file lib/silcclient/command.c.
5053 * Server does not send the invite list in INVITE command back
5054 to the client if the list was not altered. Added this notion
5055 to the protocol spec as well. Affected file silcd/command.c.
5057 Fixed possible crash in INVITE command by checking the
5058 value of silc_server_get_client_route command.
5060 * Fixed the INVITE notify type handling. The arguments are now
5061 taken in correct order and client does not crash. The affected
5062 file is irssi/src/silc/core/silc-channels.c.
5064 Removed the "Inviting xxx to channel" message from the
5065 client library away and let the application handle it.
5066 Affected file lib/silcclient/command.c. Added that message
5067 to Irssi SILC client's message formats.
5069 * Fixed CMODE command crash in client. It now checks the
5070 amount of arguments correctly and does not crash. The affected
5071 file is lib/silcclient/command.c.
5073 * Do not create new channel automatically in silc_channels_join
5074 but check whether the channel by that name already exists.
5075 Affected file irssi/silc/core/silc-channels.c.
5077 * Do not send the SERVER_SIGNOFF to router if the disconnected
5078 entity was the router. Affected file silcd/server.c.
5080 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5081 SILC client as it was missing from there.
5083 Added the handling of the KICK notify to the Irssi SILC client
5084 as it was missing. Added "you have been kicked" message to
5085 Irssi SILC client's message modules formats.
5087 Added the handing of the KILL notify to the Irssi SILC client
5088 as it was missing. Added the kill message module formats
5091 The affected file is irssi/src/silc/core/silc-channels.c.
5093 * The router did not save the channel mode the server announced.
5094 Affected file silcd/packet_receive.c.
5096 * Fixed a possible crash in INFO command in server. If the
5097 server did not provide the server info it crashed. Affected
5098 file silcd/command.c.
5100 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5102 * Fixed the GETKEY command in the server to check also the
5103 global list. Otherwise the GETKEY would not work correctly
5104 in normal SILC server. Affected file silcd/command.c.
5106 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5108 * Fixed GETKEY crash, it crashed if the command did not succseed.
5110 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5112 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5113 is now real and not just an macro interface to GMP.
5115 Removed the entire GMP from the source tree and imported new
5116 NSS MPI library instead. Reason for removing GMP is that it is
5117 extremely large and compiles extremely slow. The NSS MPI
5118 is only a few files and compiles in less than 10 seconds.
5119 The speed is also about the same as GMP. The MPI is imported
5120 to lib/silcmath/mpi.
5122 If the system has GMP installed we will still use the GMP.
5123 If it is not then the NSS MPI will be compiled.
5125 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5127 * Merged a long nickname (127 characters long) crash bugfix from
5128 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5130 * Merged a freed memory reference bugfix from Irssi CVS tree.
5131 Affected file irssi/src/core/commands.c.
5133 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5135 * Added the server's public key sving and verification to the
5136 server when performing the SKE. This was missing and the
5137 remote server's (or router's) public key was accepted without
5138 checking whether we have it previously or trust it at all.
5139 Affected file silcd/protocol.c.
5141 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5143 * Check in the silc_server_timeout_remote if protocol is active
5144 and make sure that the protocol's final callback is called so
5145 that all memory if freed. Affected file silcd/server.c.
5147 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5149 * silc_server_whois_send_reply crashed the server if the nickname
5150 was 127 characters long. Affected file silcd/command.c.
5152 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5154 * Added sanity check to the silc_server_new_client. If the hostname
5155 is provided inside username then check that the provided hostname
5156 really is the same as the resolved one. If the hostname was not
5157 resolved then check it from the public key. Affected file is
5158 silcd/packet_receive.c.
5160 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5161 if the server disconnected us and the connection is not valid
5162 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5164 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5165 the library to the lib/silcutil/silcutil.[ch].
5167 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5169 * Close log file after open. Affected file
5170 lib/silcutil/silclog.c.
5172 * Check whether sock == NULL in silc_client_send_packet and return
5173 if it is. Affected file lib/silcclient/silcclient.c.
5175 * Check rec->entry == NULL in the Irssi SILC Client before
5176 sending the channel message. Affecte file is
5177 irssi/src/silc/core/silc-servers.c.
5179 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5181 * Merged a splitted window bugfix from Irssi CVS tree. The
5182 affected file is irssi/src/fe-text/textbuffer-view.c.
5184 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5185 It did not print nickname.
5187 * Improved the distributions system a bit.
5189 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5191 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5192 irssi/src/fe-text/gui-window.c.
5194 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5195 to in-active server. The affected file is
5196 irssi/src/silc/core/client_ops.c.
5198 * Resolve the client in USERS command reply if the entry does
5199 not have username resolved. The affected file is
5200 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5201 command to WHOIS command to really resolve stuff. The USERS
5202 is not used any more in any critical section so WHOIS can
5203 be used even though it might be slower than IDENTIFY.
5205 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5208 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5210 * Changed the protocol API a bit more consistent in the
5211 lib/silccore/silcprotocol.[ch].
5213 * Changed the following headers to ROBODoc format:
5215 lib/silccore/silcpayload.h
5216 lib/silccore/silcprotocol.h
5217 lib/silccore/silcsockconn.h
5219 All core library headers are now formatted.
5221 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5223 * Fixed a bug in Irssi SILC client; do not show that you are
5224 server/router operator if you really are not. Affected file is
5225 irssi/src/silc/core/client_ops.c.
5227 * Renamed silc_command_free_payload to silc_command_payload_free.
5228 Affected file lib/silccore/silccommand.h
5230 * Added silcmath.h to include the prototoypes of various routines
5231 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5234 * Changed the following headers to ROBODoc format:
5236 lib/silccore/silcchannel.h
5237 lib/silccore/silccommand.h
5238 lib/silccore/silcid.h
5239 lib/silccore/silcidcache.h
5240 lib/silccore/silcmode.h
5241 lib/silccore/silcnotify.h
5242 lib/silccore/silcpacket.h
5243 lib/silcmath/silcmath.h
5245 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5247 * Added checking to the server code not to start the server if
5248 ciphers and stuff are not configured properly. Affected files
5249 silcd/serverconfig.[h] and silcd/server.c.
5251 * Changed the layout of the header files of the public interfaces
5252 in the SILC libraries. The new layout supports ROBODoc
5253 documentation tool (and some others) so that it is easy to create
5254 a library reference manual. All the other headers and source
5255 code must still follow the CodingStyle document. Also source
5256 code must not include these ROBODoc stuffs, only the headers.
5257 Furthermore, all public interface headers must now be named
5258 by using `silc' prefix, example: silcapi.h, silccipher.h.
5259 Some files were renamed due to this. All the other headers
5260 must not be used as public interfaces. I will update the
5261 CodingStyle document later. Changed following headers, so far:
5263 lib/silcclient/silcapi.h
5264 lib/silccore/silcauth.h
5265 lib/silccore/silcprivate.h
5266 lib/silccrypt/silcdh.h
5268 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5272 * Removed silc_client_packet_send_flush from the client library
5273 as it is not needed. Affected file lib/silcclient/client.[ch].
5275 * Added printing of message of unresolved authentication method
5276 to the Irssi SILC client. Added it to the module formats.
5277 Removed the same message from the client library.
5279 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5281 * Added new distribution feature, DISTLABEL. Every distribution
5282 can define own preprocessor label that can be used in the
5283 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5284 file distributions, acconfig.h.pre and prepare.
5286 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5288 * Added Makefile.defines_int to include the actual definitions
5289 for Makefile.defines.in. Tested the new distribution system,
5290 created distributions and tested installation.
5292 * Added AWAY message printing to the Irssi SILC client. Added
5293 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5295 * Added SCONNECT command to call the SILC's CONNECT command.
5296 Cannot use CONNECT directly since Irssi uses that internally.
5297 Affected file irssi/src/silc/core/silc-servers.c.
5299 Added ACTION local command. It is same as ME command but takes
5300 the channel as mandatory argument.
5302 Rewrote some of the Irssi's help files to suite for SILC
5305 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * Added Makefile.defines[.in] that should for now on be included
5308 in all Makefile.am file in the source tree. That file includes
5309 all common compilation definitions for SILC source tree.
5311 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5313 * Minor changes to the ./prepare script to change the package
5314 name according the distribution name to the configure.in.
5316 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5318 * Created new distribution system. Added file `distributions'
5319 that defines all the distributions that can be created out of
5320 the SILC source tree. The ./prepare script now reads that
5321 file to determine how to prepare the distributions. The
5322 first argument to the ./prepare is the name of the distribution
5323 and second is the version of the distribution. If given
5324 without arguments it creates the default (toolkit) distribution
5325 with the default version (defined in ./prepare).
5327 All Makefile.am files that are subject to the distributions
5328 are now named as Makefile.am.pre. These are ./Makefile.am
5329 and lib/Makefile.am. Others may be changed later.
5331 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Added invite list, ban list, some key management and connection
5334 error message printing to module formats in the Irssi SILC client.
5336 * Added new silc_client_set_away_message to set the away message
5337 that is back to the person who sent private message. The
5338 affected file lib/silcclient/silcapi.h and the
5339 lib/silcclient/client_prvmsg.c.
5341 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5343 * Fixed the private message sending in the Irssi SILC client,
5344 added local command KEY to the Irssi SILC client.
5346 Added key management and key agreement message formats to the
5347 irssi/src/fe-common/silc/module-formats.[ch].
5349 Added USERS (alias WHO) printing, server/router operator
5350 indication and LIST command printing to the module formats.
5352 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5354 * Fixed channel joining notify handling, cumode notify handling
5355 from Irssi SILC client.
5357 * Added SILC specific module-formats to the Irssi SILC client so
5358 that SILC specific message hilighting, colors etc is possible.
5359 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5361 Added channel mode, channel user mode, actions, notices,
5362 whois and whowas printing to the the module-formats.c.
5364 * Fixed a bug in channel deletion in the server. The channel
5365 is not left to the cache even if the channel founder auth mode
5366 is set when there are no users anymore on the channel. Affected
5367 file silcd/server.c.
5369 * The silc_net_localhost now resolves the entire hostname including
5370 the domain name. Affected file lib/silcutil/silcnet.c.
5372 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5374 * Changed the ask_passphrase client operation to be ascynchronous.
5375 It has now a completion callback and a context that the
5376 application must call after it has got the passphrase from
5377 the user. Affected files lib/silcclient/silcapi.h,
5378 lib/silcclient/protocol.c, lib/silcclient/command.c and
5381 Added SilcAskPassphrase callback that the application calls
5382 to deliver the passphrase to the library.
5384 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5385 The public key verification and especially a certificate
5386 verification is asynchronous procedure.
5388 Added new SILC_SKE_STATUS_PENDING status to indicate the
5389 request is pending and a callback will be called to finalize
5392 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5393 indicate that remote end did not send its public key (or
5394 certificate), even though we require it. Added check for this
5395 condition in the SKE. This was a security bug, now fixed.
5397 Defined new SilcSKEVerifyCbCompletion callback that is called
5398 when the verification process is completed.
5400 The affected files lib/silcske/silcske_status.h and
5401 lib/silcske/silcske.[ch].
5403 * Changed the verify_public_key client operation to be async
5404 as well. Defined SilcVerifyPublicKey callback that is used to
5405 indicate the success of the public key verification process.
5407 Changed the server and client to use the new async client
5410 * Changed the Irssi SILC client's internal scheduler to be called
5411 twice as many times as it used to be. As a result the client
5412 should be a bit faster now. Affected file is
5413 irssi/src/silc/core/silc-core.c.
5415 * Added support to Irssi SILC client of asynchronous public key
5416 verification and passphrase inquiry. Affected file is
5417 irssi/src/silc/core/silc-core.c.
5419 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5421 * Do not say "You have left channel %s" in client library.
5422 Moved it to the application. Affected files are
5423 lib/silcclient/command.c and silc/client_ops.c.
5425 * Fixed silc_client_get_clients. Command context was not
5426 duplicated and was freed memory in the callback. Affected
5427 file lib/silcclient/idlist.c.
5429 * Do not say "you are now talking..." on JOIN command in the
5430 client library. The appliation must handle it.
5432 * Do not say ".. changed topic to" in command reply in the
5433 client libary. The application must handle it.
5435 * Fixed TOPIC command sending in the client library.
5437 * Fixed a memory leak in silc_client_command_free in the file
5438 lib/silcclient/command.c.
5440 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5442 * Imported a modified version of Irssi client to the source tree.
5443 The Irssi will be used to create a new client called
5444 Irssi SILC. Imported to irssi/.
5446 Added silc_core_init_finish function to the Irssi. Affected
5447 file irssi/configure.in.
5449 A lot changes in the Makefile.ams around the irssi tree.
5451 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5453 * Do not rehash if the new size is same as the old size of the
5454 hash table, in the silc_hash_table_rehash*. The affected file
5455 lib/silcutil/silchashtable.c.
5457 * Replaced hash_table_del_by_context calls from the server
5458 (when channel->user_list and client->channels) to the
5459 hash_table_del as it is sufficient and faster.
5461 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5463 * Added silc_hash_table_list, silc_hash_table_get and the
5464 SilcHashTableList structure to provide an alternative way to
5465 traverse the hash table. The affected files are
5466 lib/silcutil/silchashtable.[ch].
5468 * Changed the server's idlist routines to use the hash table
5469 routines to optimize the code.
5471 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5473 * Replaced the client entry's `channel' list and channel entry's
5474 `user_list' list to hash tables for optimized lookup. Changed
5475 the code to use the hash table interface around the code.
5476 Affected file lib/silcd/idlist.[ch].
5478 * Added `auto_rehash' boolean argument to the function
5479 silc_hash_table_alloc to indicate whether the hash table should
5480 auto-rehash when it thinks is appropriate time. It will
5481 increase the hash table size if the there is twice as much
5482 entries in the table than the size of the table, and will
5483 decrease the size if there are twice as less entries than
5484 the size of the table.
5486 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5488 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5490 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5492 * silc_idcache_purge_by_context deletes the entry now by context
5493 as it is supposed to do. Affected file lib/silccore/idcache.c.
5495 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5496 client is not anymore valid (WHOWAS givens the info) and not
5497 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5499 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5501 * Removed the `data' and `data_len' arguments from the ID Cache
5502 interfaces and added `name' argument. ID Cache does not handle
5503 anymore the binary data only a names associated with given ID.
5505 * When hashing a Client ID with silc_hash_id the entire ID is
5506 not hashed anymore, instead only the hash of the Client ID is
5507 hashed. This way we can access the Client ID from the cache
5508 with Client ID but with the hash of the ID (which is a hash of
5509 the nickname) as well without any difference in performance.
5511 Added also silc_idcache_find_by_id_one_ext to do one on one
5512 searching when we have the actual ID. Added also function
5513 silc_hash_client_id_compare. The affected files are
5514 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5516 * When hashing the name associated with a ID it is always done
5517 in lowercase. This way we can access the cache without worrying
5518 about case-sensitivity, even though, for example nicknames are
5521 * Fixed a bug in server with channel message sending. It put
5522 wrong ID type as destination ID. The affected file
5523 silcd/packet_send.c.
5525 * silc_idcache_del_by_context now deletes from all hash tables
5526 by context. Affected file lib/silccore/idcache.c.
5528 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5530 * Changed the client library to use the new ID Cache interface.
5531 Changes around the source tree.
5533 * Added silc_hash_table_rehash_ext to rehash with specific
5534 hash function. Affected file lib/silcutil/silchashtable.[ch].
5536 * Added silc_hash_string_compare to compare two strings in the
5537 hash table. Affected file lib/silcutil/silcutil.[ch].
5539 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5541 * Added new function silc_idcache_del_by_context into the
5542 lib/silccore/idcache.[ch].
5544 * Changed the server's ID list routines to use the new ID Cache
5545 interface. Changes around the source tree.
5547 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5549 * Added silc_hash_table_del[_by_context]_ext functions in to the
5550 lib/silcutil/silchashtable.[ch].
5552 Removed silc_hash_table_find_all* routines and added new
5553 silc_hash_table_find_foreach to replace them.
5555 Added silc_hash_table_replace_ext function as extended
5556 replacing function. Separated the simple hash table interface
5557 from the extended hash table interface in the file
5558 lib/silcutil/silchashtable.h.
5560 * Fixed minor bugs and changed it to use some of the new
5561 hash table functions in lib/silccore/idcache.c
5563 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5565 * Added new function silc_hash_table_find_all to return all keys
5566 in the hash table by the specified key. As the hash table is
5567 collision resistant it also makes it possible to have several
5568 duplicate keys in the hash table. This function may be used to
5569 find all of the keys from the hash.
5571 Added user_context arguments to the SilcHashFunction,
5572 SilcHashCompare and SilcHashDestructor to deliver user specified
5575 Added new fuctions silc_hash_table_find[_all]_ext to do
5576 extended lookup with specified hash and compare functions and
5577 specified user contexts.
5579 Added new function silc_hash_table_add_ext to add the key
5580 with specified hash function and user context.
5582 Added new function silc_hash_table_foreach to traverse all
5583 entrys in the hash table. Added SilcHashForeach callback
5586 Added new function silc_hash_table_del_by_context to delete
5587 the entry only if the context associated with the key matches.
5589 Affected files are lib/silcutil/silchashtable.[ch].
5591 * Removed silc_hash_[server/client/channel]_id and added just
5592 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5593 silc_hash_id_compare to compare two ID's using as the hash table
5594 comparison function. Added also silc_hash_data to hash
5595 binary data and silc_hash_data_compare to compare it.
5597 * Removed silc_idlist_find_client_by_hash as it is not needed
5598 anymore. Affected file silcd/idlist.[ch].
5600 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5601 to use internally the SilcHashTable. The new ID Cache is a lot
5602 faster than the old one. Some of the ID Cache interface was also
5603 rewritten and obsolete and stupid functions were removed.
5605 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5607 * Added entry_count field to the SilcHashTable to keep the number
5608 of the entries in the table. Implemented the function
5609 silc_hash_table_rehash. Added new function
5610 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5612 Fixed a minor bug in silc_hash_table_free.
5614 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5615 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5616 into the lib/silcutil/silcutil.[ch].
5618 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5620 * Implemented a collision resistant hash table into the
5621 lib/silcutil/silchashtable[ch]. See the header and the source
5622 for the SilcHashTable API.
5624 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5626 * Merged dotconf version 1.0.2 into lib/dotconf.
5628 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5630 * Do not compile anything in lib/silcsim/* if the SIM support
5631 is not enabled. The tree should now compile without problems
5634 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5636 * Compiled the SILC under cygwin. Compiled and tested briefly
5637 without problems. More tests needed. The SIMs didn't compile
5640 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5642 * Fixed possible crash in silc_get_username in the
5643 lib/silcutil/silcutil.c.
5645 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5647 * Fixed a va_arg in silc/client_ops.c.
5649 * Oops, RC5 routines were named AES and caused some problems
5650 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5652 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5654 * Added new SilcIDIP structure into the lib/silccore/id.h and
5655 replaced the old `ip' fields from all SILC ID's to that type.
5656 This is a step towards IPv6 support.
5658 The silc_id_get_len takes now the ID as an extra argument.
5659 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5660 both IPv4 and IPv6 based ID's.
5662 The affected files are lib/silccore/id.[ch] and other files
5663 around the tree using these routines.
5665 * Removed the ID length arguments in server from various
5666 silc_server_send_notify_* routines -> they are not needed
5669 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5671 * Fixed memory leak in silc_encode_pem_file in the file
5672 lib/silcutil/silcutil.c.
5674 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5676 * Check minor version as well in the SKE. Affected files are
5677 silcd/protocol.c and lib/silcclient/protocol.c.
5679 * Added --identifier option to the server so that an identifier
5680 can be when creating the public key for the server. Affected
5681 file is silcd/silcd.c.
5683 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5684 lib/silccrypt/silcpkcs.c.
5686 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5688 * Register default ciphers and stuff when using -C option with
5689 the server. Affected file sildc/silcd.c.
5691 * Put back the servers public key filename format, it is better
5692 than the new one. For now, the client keys are saved with the
5693 new filename format. The affected file silc/client_ops.c.
5695 * Implemented the Cipher API for the rest of the ciphers that
5696 did not implement it or implemented it the wrong way.
5698 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5700 * Register default ciphers and stuff when using the -S option
5701 in the client. Affected file silc/silc.c. Same also when
5702 creating new key pair with -C option.
5704 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5706 * Fixed the silc_verify_public_key client operation function to
5707 save the public keys differently. The fingerprint is now
5708 used as filename and not the hostname. This way also the
5709 client keys are saved uniquely and not with hostnames. The
5710 affected file is silc/client_ops.c.
5712 * Trimmed the silc_hash_fingerprint function to remove extra
5713 whitespaces from the end of the fingerprint. The affected
5714 file is lib/silccrypt/silchash.c.
5718 * Added silc_cipher_register_default function to register all
5719 default ciphers. It can be used when configuration files
5720 does not exist and the application does not want any specific
5721 ciphers in any specific order.
5723 The SilcDList is now used as silc_cipher_list dynamically
5724 allocated cipher list. Removed the static list all together
5725 and now all ciphers must be allocated to the dynamic list.
5726 The silc_cipher_alloc routine was changed to check only the
5729 All silc_cipher_* routines that used to return int returns
5732 The affected files lib/silccrypt/silccrypt.[ch].
5734 * The same thing was done to silc_hash_* as for silc_cipher_*
5735 routines. Affected files lib/silccrypt/silchash.[ch].
5737 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5738 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5739 Added also silc_pkcs_[un]register[_default] functions.
5740 Removed the data_context from the PKCS API.
5742 * Added silc_hmac_register_default function to register default
5743 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5744 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5745 to unregister all hmacs at once.
5747 * Register the default ciphers, hash functions, PKCSs and HMACs
5748 if client's configuration file does not exist. The affected
5751 * The client did not load the hash functions from the SIM
5752 modules at all. Added support for this. Affected file is
5753 silc/clientconfig.c.
5755 * When decoding public key with silc_pkcs_public_key_decode, check
5756 the supported algorithm only if PKCS are registered. Affected
5757 file lib/silccrypt/silcpkcs.c. The same was done with the
5758 silc_pkcs_private_key_decode.
5760 * Fixed the SILC List routines to keep the list always in order.
5761 It used to change the list's order when traversing the list but
5762 not it preserves the order. Affected file lib/trq/silclist.h.
5764 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5766 * Added the client library to use the SilcSocketConnection's
5767 reference counter (by silc_socket_dup) to prevent the bug that
5768 the socket object may be freed underneath async operation.
5770 * The name resolv library checking fixes in the configure.in.pre.
5773 * Created new version of the protocol drafts for future
5774 development. The -03 drafts are the ones that will be changed
5775 in the trunk now and the -02 will remain as they are.
5777 * Send list of CUMODE notifys to the router when announcing
5778 the channel users to the router. Affected file silcd/server.c.
5779 If the router receiving channel founder CUMODE for a channel
5780 that already has channel founder it will send CUMODE notify
5781 to the sender to remove the channel founder rights from the
5782 announced client. Affected file silcd/packet_receive.c.
5784 * The CUMODE notify may now use Server ID as well as the entity
5785 who changes the mode. Updated protocool specs.
5787 * Updated INSTALL and README files.
5789 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5791 * New web pages in the http://silc.pspt.fi. The pages was
5796 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5798 * Implemented the [DenyConnectin] config section in the server.
5799 Added silc_server_config_denied_conn to check whether incoming
5800 connection is denied. Affected file silcd/serverconfig.[ch].
5802 * Do not check the ports when checking the incoming configuration
5803 data if the port is 0, meaning any. Affected file is
5804 silcd/serverconfig.c.
5806 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5808 * Fixed buffer overflow in silc_string_compare in the file
5809 lib/silcutil/silcutil.c.
5811 * Fixed double free in silc_server_command_leave in the file
5814 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5816 * Fixed the version checking in the server. Affected file is
5819 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5821 * Fixed the configuration data fetching when accepting new
5822 connections in the server. Affected file silcd/server.c.
5824 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5826 * Added `sender_entry' argument to the function
5827 silc_server_packet_relay_to_channel so that we can check
5828 whether some destination actually belongs to the same route
5829 the sender belongs (ie, we must not resend the packet to the
5830 sender). Affected file silcd/packet_send.[ch].
5832 * Added `servername' field to the SilcClientEntry in the server
5833 to hold the name of the server where client is from. Affected
5834 file is silcd/idlist.h.
5836 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5838 * Moved the channel message encrypting in the router betwen
5839 router connections from silc_server_channel_message to the
5840 silc_server_packet_relay_to_channel since we want to check
5841 whether we have anybody channel before encrypting anything.
5842 Affected files silcd/packet_[receive/send].c.
5844 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5846 * Fixed the [AdminConnection] server config section to support
5847 multiple entries. Affected file silcd/serverconfig.c.
5849 * Added support into the server to check the validity of the
5850 incoming connection before executing any KE or authentication
5853 * The connection configuration is now saved to the KE and
5854 connection auth protocol contexts and not fetched anymore in
5855 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5857 * The local hosts listenning address and port is also resolved
5858 now when starting the server. We want to have the socket object
5859 to include the real address and port for the listener. Added
5860 new function silc_net_check_local_by_sock into the files
5861 lib/silcutil/silcnet.[ch].
5863 * Fixed a broadcast bug in server -> do not broadcast if we
5866 * Fixed a routing bug. Do not route broadcast packets ever.
5867 Broadcast packets must be processed always and not routed since
5868 they may be destined to some other host than yourself and thus
5869 would get routed without no good reason. Affected file is
5872 * Added function silc_server_config_is_primary_route to check
5873 whether primary router connection has been configured (a router
5874 configuration that we are initiating). If there is not, we
5875 will assume that there is only two routers in the SILC network
5876 and we will use the incoming router connection as our primary
5877 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5879 * Changed the order of the broadcasting. Broadcast _after_ the
5880 packet has been processed not before. Affected file is
5883 * Fixed a [ClientConnection] parsing bug. The port was never
5884 parsed correctly thus resulting to port 0. Affected file
5885 silcd/serverconfig.c.
5887 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5888 argument and did not set the broadcast packet flag. Affected
5889 file silcd/packet_send.c. Fixed same bug in the function
5890 silc_server_send_notify as well.
5892 * If we receive NEW_ID packet for our own ID in the server, ignore
5895 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5899 * Removed the nickname from the Private Message Payload.
5900 Updated the code and the protocol specs.
5902 * Updated protocol specs for submitting to the IETF.
5904 * Tweaked the Random Number Generator a bit. Affected file
5905 lib/silccrypt/silcrng.c. Exported a new function
5906 silc_rng_[global]_add_noise which can be used to add more
5909 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5911 * Do not parse packets with different timeout when protocol
5912 is active -> may cause problem with rekey. Affected file
5915 * When server receives signoff notify it must not create
5916 new channel key if the client is on any channels since the
5917 sender of the signoff notify will create it.
5919 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5921 * Added printing of error messages during SKE protocol from the
5922 failure packet sent by server during SKE. Affected file
5925 * Removed the client's failure_callback handling with timeout
5926 and handle it immediately when received.
5928 * The SKE library returned wrong type in SUCCESS and FAILURE
5929 packets. They must be 32 bit MSB not 16 bit MSB.
5931 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5933 * Ok, rewrote the logic of the re-key and now it seems to work.
5934 I tested it on high traffic with frequent re-keys without
5935 problems. Added hmac_receive (and renamed hmac to hmac_send)
5936 in SilcClientConnection in lib/silcclient/client.h and
5937 in SilcIDListData in silcd/idlist.h. Also, removed the
5938 SilcPacketParserContext's cipher and hmac fields as they are
5939 not needed anymore and actually caused some problems when
5940 the ciphers and hmac's changed underneath the packet parser.
5942 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5944 * If re-key protocol is active then process the incoming packets
5945 synchronously since we must assure that icoming packets encrypted
5946 with the old key is processed before the new keys is set to
5947 use. This is true other packets than for REKEY packets.
5948 Affected file silcd/server.c. The same was done to client library
5949 as well, affected file lib/silcclient/client.c.
5951 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5953 * Fixed bug in client and server to accept the force send if
5954 the packet is send from silc_[server/client]_packet_process
5955 function. Otherwise the packets are never delivered, oops.
5957 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5959 * Disable force sending of packets when REKEY protocol is active.
5960 We must assure that no packet is sent directly when rekey is
5961 performed. All packets must be sent through packet queue.
5962 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5963 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5964 function is silc_[server/client]_packet_send_real to check
5967 * Replaced the SIM paths from example config files to
5968 /usr/local/modules. Also, make install creates now
5969 /usr/local/silc/logs directory to hold all the SILC server
5972 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5974 * Made the configure.in.pre work on Solaris. Patch by salo.
5976 * Made all ciphers compatible with non-x86 machines. Defined
5977 CBC mode macros into lib/silccrypt/ciphers_def.h.
5979 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5981 * Fixed the make install.
5983 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5985 * When MAC computation fails the silc_packet_decrypt returned 0
5986 even though it was supposed to return -1. Fixed this. The
5987 affected file is lib/silccore/silcpacket.c.
5989 * Do not replace the config files in /etc/silc (in make install)
5990 if they already exist. Affected file ./Makefile.am.
5992 * Do not send re-key packets immediately but through packet queue.
5993 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5995 * Changed silc_net_check_host_by_sock to return FALSE if the
5996 IP/DNS could not be resolved. Though, it returns the IP address
5997 now even if it could not resolve it (but returns also FALSE).
5998 Affected file lib/silcutil/silcnet.[ch].
6000 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6002 * Added silc_pkcs_decode_identifier to decode the public key's
6003 identifier. Affected file lib/silccrypt/silpkcs.[ch].
6004 Added also silc_pkcs_free_identifier. Added also new context
6005 SilcPublicKeyIdentifier.
6007 * Added -S option to the silc client. It is used to dump the
6008 contents of the specified public key file.
6010 * Changed the PKCS api to return the public key length when
6011 setting the public key.
6013 * Fixed a fatal bug in the public and private key file loading.
6014 Affected file lib/silccrypt/silcpkcs.c.
6016 * Execute the packet parsing for client with zero (0) timeout
6017 if the protocol is active. Affected file silcd/server.c.
6019 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6021 * Made the key generation options to the silcd program. Added
6022 -C option, equivalent to client's option.
6024 * Added new [ServerKeys] config section to the server. It
6025 configures the server's public and private key.
6027 * Defined generic Public Key Payload into the protocol
6028 specification to send specific type of public keys and
6031 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6032 public key or certificate.
6034 * Implemented the GETKEY command to the server and to the
6035 client library and on user interface.
6037 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6039 * Made preliminary `make install' work.
6041 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6043 * Added SilcServerRekey context into silcd/idlist.h.
6045 * Added the PFS support as defined in the specification to the
6046 SKE protocol. Affected files lib/silcske/*.c.
6048 * Added `ske_group' field to the SilcServerRekey context to hold
6049 the number of the SKE group that is used with PFS in re-key.
6050 Affected file silcd/idlist.h.
6052 * Added PFS re-key support to the server. Affected file is
6055 * Added silc_protocol_cancel to cancel execution of the next
6056 state of the protocol. Affected file is
6057 lib/silccore/silcprotocol.[ch].
6059 * Added the re-key support with and without PFS to the client
6060 library. Re-key is performed once in an hour, by default.
6062 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6063 Added silc_client_rekey_callback and silc_client_rekey_final.
6064 Affected files are lib/silcclient/protocol.[ch] and
6065 lib/silcclient/client.[ch].
6067 * Removed the `hmac_key' and `hmac_key_len' fields from the
6068 SilcClientConnection structure; not needed. Affected file is
6069 lib/silcclient/client.h.
6073 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6075 * Do not ask whether user wants to use the negotiated private key
6076 for private messages, just use it. Affected file is
6077 silc/local_command.c.
6079 * Added `send_enc_key' and `enc_key_len' fields to the
6080 SilcIDListData structure since they are needed in the re-key
6081 phase. Affected file is silcd/idlist.[ch].
6083 * Implemented the simple re-key protocol into the server.
6084 Affected files silcd/server.c and silcd/protocol.[ch]. The
6085 re-key will be performed once in an hour, by default.
6087 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6088 Added silc_server_rekey, silc_server_rekey_callback and
6089 silc_server_rekey_final.
6091 * Removed Tunneled flag from the protocol. Updated the code
6092 and the specifications.
6094 * Adde `pfs' field to the SilcIDListData to indicate whether
6095 the PFS is to be performed in the re-key. Affected file is
6098 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6100 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6101 int64 of at least the xintXX size. If void * is less that 4
6102 bytes uint32 * will be used. Defined bool as boolean.
6104 * Changed _ALL_ unsigned long and unsigned int to uint32,
6105 unsgined short to uint16 in the source tree.
6107 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6108 not handle clients that has entry->data.registered == FALSE.
6109 They are not in the network anymore. Affected file is
6112 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6114 * Implemented the sending of the SERVER_SIGNOFF notify in the
6115 server. Affected file is silcd/server.c.
6117 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6118 Added also silc_notify_payload_encode_args into the
6119 lib/silccore/silcnotify.[ch].
6121 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6122 Affected file silcd/packet_receive.c.
6124 * Implemented the SERVER_SIGNOFF notify handling in the client
6125 library. Affected file lib/silcclient/client_notify.c. Also,
6126 implemnted the printing of the SERVER_SIGNOFF info to the
6127 application. Affected file silc/client_ops.c.
6129 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6130 if the deleting was successful. Affected file silcd/idlist.[ch].
6132 * Added support for public key authentication in the connection
6133 authentication protocol in the client library. Affected file
6134 lib/silcclient/protocol.c.
6136 * Changed the server's silc_idlist_get_clients_by_* interface
6137 to support already allocated array so that new entries may be
6138 added to pre-allocated array. Affected file silcd/idlist.[ch].
6139 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6140 and command replies.
6142 * All command reply functions in the server now calls the
6143 pending command callback even if error occured. This way the
6144 error will be delivered to the client as well. Affected files
6145 silcd/command.c and silcd/command_reply.c.
6147 * Fixed INFO command to return local server's info if no server
6148 was provided. Affected file lib/silcclient/command.c.
6150 * Removed RESTART command for good. Updated the code and the
6153 * Rewrote parts of the task system. It is a bit simpler now.
6154 Removed unsued task priorities. The affected files are
6155 lib/silcutil/silctask.[ch].
6157 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6159 * Moved the USERS printing from the library to the application.
6160 Affected files lib/silcclient/command.c and silc/client_ops.c.
6162 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6166 * Added channel key re-key support. The re-key is perfomed
6167 only by the router and is done once in an hour. Added `rekey'
6168 field to the SilcChannelEntry in the server. Affected files
6169 silcd/server.c and silcd/idlist.h.
6171 * Added silc_task_unregister_by_context into the file
6172 lib/silcutil/silctask.[ch].
6174 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6176 * Added SILC_UMODE_GONE mode to indicate when the client is not
6177 present in the SILC network. Added also support to the local
6178 command AWAY that will set this mode. Added support of showing
6179 "xxx is gone" in WHOIS command. The USERS command shows the
6180 gone status as well.
6182 * Fixed setting server and router operator privileges in the
6183 server's UMODE command. Affected file silcd/command.c.
6185 * Merged the SKE KE1 and KE2 payloads into one payload. The
6186 new KE payload is equivalent to the old KE2 payload.
6188 Cleaned up the SKE Start Payload parsing. It now uses the
6189 simple buffer unformatting to do the parsing. A lot faster
6192 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6193 to the SKE that is used to indicate whether both of the SKE
6194 parties should perform authentication. By default only the
6195 responder performs authentication. By setting this flag also
6196 the initiator must do authentication. By default it is unset
6197 since in normal SKE case, client to server connection, only
6198 the responder should do authentication. When doing SKE between
6199 two clients both should perform authentication. Updated the
6200 code and the protocol specs.
6202 * A little fix to IDENTIFY command in the server. Search the
6203 client first by hash not nickname. Affected file is
6206 * Fixed the silc_client_close_connection to support closing
6207 the client to client connections wihtout deleting too much
6208 data. Affected file lib/silcclient/client.c.
6210 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6211 are received if protocol used to be active but is not anymore
6212 the application would crash due to NULL pointer dereference.
6213 Affected files silcd/server.c and lib/silcclient/client.c.
6215 * Added `hash' field to the SilcClientConnection to include
6216 the hash function negotiated in the SKE protocol.
6218 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6219 to set the channel founder authentication data. A client can
6220 claim the founder rights later by providing the authentication
6221 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6222 This way the channel founder can regain the channel founder
6223 privileges even it is left the channel. This works only on
6224 local server and the client must be connected to the same
6225 server to be able to regain the founder rights. Updated the
6226 protocol specs accordingly.
6228 Added support to the CMODE command in the client to set the
6229 founder auth data. Read the README to see how to set it.
6231 Added support to the CUMODE command to claim the founder
6232 rights. Read the README to see how to do it.
6234 Added support for the founder authentication to the Channel
6235 Entry in the server. Affected file silcd/idlist.h.
6237 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6238 server's CMODE command. Affected file silcd/command.c.
6240 * Added the following new functions into lib/silccore/silcauth.[ch]:
6241 silc_auth_get_method and silc_auth_get_data.
6243 * The server now saves the remote hosts public key to the
6244 SilcIDListData pointer. Affected file silcd/protocol.c.
6246 * The normal server now does not remove the channel entry from
6247 the cache if the founder authentication data is set. It used
6248 to remove it if the founder was the last one on the channel on
6249 the server and left the channel. The auth data is saved and
6250 if the channel is re-joined later the old entry is used with
6251 the old auth data. Affected files silcd/command_reply.c and
6254 * Removed the `pkcs' field from the SilcIDListData structure
6255 in the server; it is not used. Affected file silcd/idlist.h.
6257 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6259 * Fixed packet processing on slow links. Partial packets were
6260 never re-processed because the incoming data buffer was cleared
6261 by the application. Application must not directly clear the
6262 sock->inbuf, the packet processing routines handle it. Fixed
6263 this in client library and in server.
6265 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6267 * Fixed the WHOIS and IDENTIFY send reply function to really
6268 check whether to send list or just one entry. Affected file
6271 * Cleaned up the LEAVE command's channel key distribution. The
6272 affected file silcd/command.c.
6274 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6275 can enforce the channel mode as well. In that case the ID
6276 includes the ID of the server. The code now enforces the
6277 mode change if the router have different mode than the server.
6279 * The notify client operation with CMODE_CHANGE notify can now
6280 return NULL client_entry pointer if the CMODE was not changed
6281 by client. Application must check for this.
6283 * Added <Server ID> argument to INFO command to support server
6284 info fetching by Server ID.
6286 * Added silc_server_announce_get_channel_users to get assembled
6287 packets of channel users of the specified channel. Affected
6288 file silcd/server.[ch].
6290 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6291 was freed underneath the ID Cache.
6293 * Re-announce clients when the server received CHANNEL_CHANGE
6294 notify from the router. Affected file silcd/packet_send.c.
6296 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6298 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6299 crashed since it did not handle the fact that there is no cipher
6300 called "3" and didn't check the error condition. Now fixed.
6302 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6303 flag. It can be used to send message requests.
6305 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6307 * Implemented the RESTART command in the client.
6309 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6310 notice type messages. Added notice printing to the user
6313 * The channel keys are not re-generated if the channel's mode
6314 is PRIVKEY, ie private key on the channel exists. Affected
6315 files silcd/server.c and silcd/command.c.
6317 * Fixed a little bug in channel message delivery when channel
6318 private keys are set in the server. Affected file is
6319 silcd/packet_send.c.
6321 * Changed the setting on channel->on_channel = TRUE from the
6322 silc_client_save_channel_key to the JOIN command reply. The
6323 key payload is not received if the private channel key is set.
6324 Affected file lib/silcclient/command_reply.c and the
6325 lib/silcclient/client_channel.c.
6327 * When the CMODE_CHANGE notify is sent and the channel private
6328 key mode is removed the channel key must be re-generated in
6329 other cells as well. Added this support for the router in the
6330 silcd/packet_receive.c.
6332 * Added new local command NOTICE to send notice message on
6333 channel. Affected file silc/local_command.[ch].
6335 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6337 * Added new local command ME to the client. It is used to send
6338 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6339 some action. Affected file silc/local_command.[ch].
6341 * Changed channel_message and private_message client operations
6342 to deliver the message flags to the application. Added also
6343 the `flags' arguments to the silc_client_send_channel_message
6344 and silc_client_send_private_message functions. Affected file
6347 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6349 * Redefined the Private Message Payload to support private message
6350 keys and to support the new private message flags. Updated
6351 the protocol specs. Flags makes it possible to have for example
6352 CTCP style messages.
6354 * Added new type SilcPrivateMessagePayload and defined an API
6355 for it in the lib/silcclient/silcprivate.[ch].
6357 * Tested private message private keys successfully. Tested the
6358 private message key set, unset and list commands with the new
6361 * Redefined the Channel Message Payload to include the channel
6362 message flags (equal with private message flags) to support
6363 for example CTCP style messages.
6365 * Defined some of the message (for channel and private message)
6366 flags. Updated the protocol specs and added the flags to the
6367 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6369 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6371 * Added SilcKeyAgreementStatus type to the key agreement routines
6372 to indicate the current status and error if one occured.
6373 The status types are defined in the lib/silcclient/silcapi.h.
6375 * Added new local command KEY that is used to set and unset private
6376 keys for channels, set and unset private keys for private messages
6377 with remote clients and to send key agreement requests and
6378 negotiate the key agreement protocol with remote client. The
6379 key agreement is supported only to negotiate private message keys,
6380 it currently cannot be used to negotiate private keys for channels,
6381 as it is not convenient for that purpose.
6383 * Fixed a minor pending callback setting bug in the function
6384 silc_client_get_client_by_id_resolve, now the function works.
6385 Affected file lib/silcclient/idlist.c.
6387 * Added function silc_net_get_local_port to get local bound
6388 port by socket. Added to lib/silcutil/silcnet.[ch].
6390 * Added `sockets' and `sockets_count' fields to the SilcClient
6391 object. They hold the sockets of the listenning sockets in
6392 the client. Listenning sockets may be for example the key
6393 agreement server. Affected file lib/silcclient/client.[ch].
6394 Added functions the silc_client_add_socket and the
6395 silc_client_del_socket. They are exported to the application
6398 * Added ~./silc/clientkeys to support other client's public keys.
6400 * Renamed verify_server_key client operation to verify_public_key
6401 and added one argument to indicate the type of the connection
6402 (server, client etc.).
6404 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6406 * Added silc_server_connection_auth_request to handle the
6407 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6408 silcd/packet_receive.[ch].
6410 * Added silc_server_send_connection_auth_request into the
6411 silcd/packet_send.c to send the connection auth request packet.
6413 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6416 * Fixed the public key authentication in responder side in the
6417 server. The `auth_data' pointer includes the SilcPublicKey
6418 not the path to the public key. Affected file silcd/protocol.c.
6420 * Implemented the public key authentication in the initiator side
6421 in the server. Affected file silcd/protocol.c.
6423 * Removed the [RedirectClient] config section from the server
6424 configuration. Is not needed and I don't want to implement it.
6426 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6428 * Cleaned up the CMODE command in the server. It now works
6429 correctly and supports all the modes defined in the protocol.
6430 Affected file is silcd/command.c.
6432 * Added `hmac_name' field to the SilcChannelEntry in the server
6433 to hold the default HMAC of the channel. It can be set when
6434 creating the channel (with JOIN command). Affected files
6437 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6438 type to indicate the change of the current cipher and hmac
6439 on the channel. Client can safely ignore the <cipher> argument
6440 (if it chooses to do so) since the CHANNEL_KEY packet will
6441 force the channel key change anyway. The <hmac> argument is
6442 important since the client is responsible of setting the new
6443 HMAC and the hmac key into use.
6445 * Fixed the CMODE command in the client library as well.
6447 * Tested CMODE command in router environment successfully.
6449 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6451 * Show the version of the remote client (or server) when connecting
6452 to the server. It is logged to the log file. Affected file
6453 is silcd/protocol.c.
6455 * Fixed the KILLED notify handling in the client library. The
6456 client must be removed from all channels when receiving the
6459 Also, do not remove the client entry when giving the KILL
6460 command but when the KILLED notify is received.
6462 * Removed silc_idlist_find_client_by_nickname from the server.
6463 Not needed anymore. Affected files silcd/idlist.[ch].
6465 * Implemented the CHANNEL_CHANGE notify type handling to the
6466 server. Affected file silcd/server.c.
6470 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6472 * Added silc_server_send_notify_invite to send the INVITE
6473 notify between routers.
6475 * Implemented the INVITE command correctly to the server.
6477 * Implemented the INVITE notify type handling in the server.
6479 * Implemented the INVITE command to the client library and on the
6482 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6484 * Added function silc_server_get_client_resolve to find the
6485 client entry by ID from all ID lists and then resolve it
6486 (using WHOIS) if it cannot be found. Affected file is
6489 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6491 * Implemented the BAN command to the client library.
6493 * The JOIN command in the server now checks the invite list
6496 * Changed the silc_command_reply_payload_encode_va and the
6497 silc_command_payload_encode_va to support that if argument is
6498 NULL it ignores and checks the next argument. Affected file
6499 lib/silccore/silccommand.c.
6501 * Added silc_server_send_notify_ban to send the BAN notify
6502 type between routers.
6504 * Chaned the silc_notify_payload_encode to support that if
6505 argument is NULL it ignores and checks the next argument.
6506 Affected file lib/silccore/silcnotify.c.
6508 * Tested ban lists in router environment successfully.
6510 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6512 * Implemented BAN command to the server, in silcd/command.[ch].
6514 * Removed the BAN and INVITE_LIST modes from the CMODE command
6517 * Added function silc_string_match to regex match two strings.
6518 Affected files lib/silcutil/silcutil.[ch].
6520 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6522 * Redefined parts of the SilcChannelEntry in the server to support
6523 the new ban and invite lists.
6525 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6527 * Redefined the INVITE command. The same command can be used to
6528 invite individuals to the channel but also to manage the invite
6529 list of the channel (to add to and remove from the invite list).
6530 Updated the protocol specs.
6532 * Added new command SILC_COMMAND_BAN that can be used to manage
6533 the ban list of the channel. Updated the protocol specs.
6535 * Removed the channel modes: the SILC_CMODE_BAN and the
6536 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6537 in the CMODE command. The equivalent features are now available
6538 using INVITE and BAN commands. Updated the protocol specs.
6540 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6541 in the network about change in the current ban list. The notify
6542 type is not used by the client.
6544 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6545 support the invite lists.
6547 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6549 * Added new function silc_string_regexify that converts string
6550 including wildcard characters into regex string that can
6551 be used by the GNU regex library. Added into the file
6552 lib/silcutil/silcutil.[ch].
6554 Added silc_string_regex_combine to combine to regex strings
6555 into one so that they can be used as one regex string by
6556 the GNU regex library. Added into the file
6557 lib/silcutil/silcutil.[ch].
6559 Added silc_string_regex_match to match two strings. It returns
6560 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6562 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6564 * Imported GNU regex to the soruce tree into lib/contrib.
6565 Fixed some compiler warning from the regex.c.
6567 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6569 * Fixed MOTD command in the server to work in router environment.
6571 * Fixed the MOTD command in the client library to support
6572 the server argument in the command.
6574 * Added `nickname_len' argument to the silc_idlist_add_client
6575 in the server, as the `nickname' argument may be binary data
6578 * Added silc_idlist_get_channels to return all channels from
6581 * Implemented LIST command to the server. Affected file is
6584 * Implemented the LIST command to the client library and on the
6587 * Added [<user count>] argument to the LIST command reply.
6588 With private channels the user count is not shown.
6590 * Updated TODO and README.
6592 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6594 * The client entry's data.registered must be TRUE even with
6595 global client entry on global client list. The data.registered
6596 is used to check whether the client is anymore in the network,
6597 for example with WHOWAS command so it must be valid.
6599 * Fixed the WHOWAS command in the server. It now actually works
6600 in router environment. Added function into silcd/command_reply.c
6601 silc_server_command_reply_whowas_save.
6603 * Added silc_idlist_purge function to the silcd/idlist.c
6604 to periodically purge the ID Cache.
6606 * Fixed INFO command in the server. It works now in router
6607 environment. Added <server name> argument to the INFO command
6608 reply. Updated the protocol specs.
6610 * Fixed minor bug in silc_idcache_purge to not purge if the
6611 expire value is zero.
6613 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6614 they were buggy because of the WHOWAS information.
6616 * Fixed local command MSG to handle the async resolving of
6617 the remote client properly. It used to fail the first MSG.
6618 Affected file silc/local_command.c.
6620 * Added `data_len' field to SilcIDCache context.
6622 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6624 * Update TODO. Todo in commands in the server.
6626 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6628 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6629 used by routers as broadcast packet to inform other routers
6630 about the changed user mode.
6632 Implemented the notify handling in the server. Affected file is
6633 silcd/packet_receive.c. Added the function
6634 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6636 * Added new generic Channel Payload and deprecated the New Channel
6637 Payload. The New Channel Payload is now the generic Channel
6640 * Added new argument `mode' to the silc_server_send_new_channel
6641 as it is required in the Channel Payload now.
6643 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6644 and created a new and real SilChannelPayload to represent the
6645 new generic Channel Payload. Implemented the encode/decode
6646 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6648 * Added silc_server_get_client_channel_list to return the list
6649 of channels the client has joined for WHOIS command reply.
6650 Affected file silcd/server.[ch].
6652 * Implemented the channel list sending in the WHOIS command reply
6653 in server and in the client.
6655 Implemented the channel list displaying on the user interface
6656 as well. Affected file silc/client_ops.c.
6658 * Added silc_channel_payload_parse_list to parse list of Channel
6659 Payloads. It returns SilcDList list of SilcChannelPayloads.
6660 Client for example can use this function to parse the list of
6661 channels it receives in the WHOIS command reply. The caller
6662 must free the list by calling silc_channel_payload_list_free.
6663 Affected files lib/silccore/silcchannel.[ch].
6665 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6667 * Added one new argument <user mode> to the WHOIS command reply
6668 to return the mode of the user in SILC. Updated the protocol
6671 Implemented it to the server and client.
6673 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6675 * Fixed the mode printing on the user interface on joining.
6676 Affected file silc/client_ops.c.
6678 * Implemented the UMODE command and user modes in general to the
6679 client library and to the user interface.
6681 * Implemented the UMODE command to the server.
6683 * The server now sends UNKNOWN_COMMAND error status if client sends
6684 unknown command. Affected file silcd/command.c.
6686 * All server commands now handle the command identifier the right
6687 way when sending the command reply to the client. The client can
6688 use to identify the command replies with the identifier.
6690 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6692 * Added silc_server_get_client_route to resolve the route to
6693 the client indicated by the client ID. Affected file is
6696 * Added silc_server_relay_packet as general function to relay
6697 packet to arbitrary destination. This deprecates functions
6698 like _send_private_message_key, _relay_notify etc. Affected
6699 file is silcd/packet_send.[ch].
6701 Removed silc_server_send_key_agreement,
6702 silc_server_send_private_message_key and
6703 silc_server_packet_relay_notify functions from the file
6704 silcd/packet_send.[ch].
6708 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6709 server. Affected file silcd/packet_receive.[ch].
6711 * Implemented the KILL command to the client. Implemented the
6712 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6713 Affected files lib/silcclient/command[_reply].c and
6714 lib/silcclient/client_notify.c. Implemented the KILL notify
6715 printing in the user inteface.
6717 * Fixed a lot silc_parse_nick memory leaks from the client
6718 library in the file lib/silcclient/command.c.
6720 * Changed the silc_server_send_notify_on_channels's `sender'
6721 argument from SilcSocketConnection to SilcClientEntry to
6722 check the sender as entry and not as connection object and not
6723 to send to the client provided as argument. The affected file
6724 is silcd/packet_send.[ch].
6726 * The notify packets that are destined directly to the client used
6727 to not to be processed by the server. Now changed that and the
6728 server processes all notify packets. After relaying the packet
6729 to the client the notify packet is processed in the server.
6731 * The silc_server_free_client_data now checks whether there is
6732 pending outgoing traffic for the client and purges the data to
6733 the network before removing the client entry.
6735 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6737 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6738 an client is killed from the SILC Network. Updated the protocol
6741 Added new function silc_server_send_notify_killed to the
6742 silcd/packet_send.[ch].
6744 * Added function silc_server_packet_relay_notify to relay notify
6745 packets that are destined directly to a client. In this case
6746 the server does not process the notify packets but merely relays
6747 it to the client. Affected file silcd/packet_send.[ch].
6749 Added also silc_server_packet_process_relay_notify to check
6750 whereto relay the notify. Affected file is
6751 silcd/packet_receive.[ch].
6753 * Implemented the KILL command to the server.
6757 * Added the backup schema desgined last fall to the protocol
6758 specs for everyone to see. The specification is in the
6759 *-spec-xx.txt draft and the packet type definitions for the
6760 backup routers is in *-pp-xx.txt draft. Thusly, added also
6761 new packet type SILC_PACKET_CELL_ROUTERS.
6763 * A big security problem in the implementation discovered. The
6764 signoff of an client did not cause new channel key generation
6765 which it of course should've done. The channel keys must be
6766 always re-generated when client leaves (or signoffs) the channel.
6767 The silc_server_remove_from_channels funtion now handles
6768 the channel key re-generation.
6770 * Added `sender' argument to the silc_server_send_notify_on_channels
6771 to not to send the client provided as argument. Affected file
6772 silcd/packet_send.[ch].
6774 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6776 * Implemented OPER and SILCOPER commands into the server and
6779 * Added silc_auth_verify and silc_auth_verify_data to verify
6780 the authentication directly from the authentication payload.
6781 It supports verifying both passphrase and public key based
6782 authentication. Affected file lib/silccore/silcauth.[ch].
6784 * Added `hash' field to the SilcIDListData structure. It is the
6785 hash negotiated in the SKE protocol. Affected file is
6788 * Slight redesigning of the SilcAuthPayload handling routines.
6789 Do not send SilcPKCS but SilcPublicKey as argument.
6791 * Implemented the public key authentication support to the
6792 serverconfig. The public key is loaded from the provided path
6793 and saved as authentication data to void * pointer. Thus,
6794 changed the unsigned char *auth_data to void *auth_data;
6796 * Fixed SHUTDOWN command to send the reply before the server
6797 is shutdown. :) Affected file silcd/command.c.
6799 * Fixed fatal bug in CONNECT command. The hostname was invalid
6800 memory and server crashed. Affected file silcd/command.c.
6802 * Fixed fatal bug in CLOSE command. The server_entry became
6803 invalid but was referenced later in the command. Affected file
6806 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6808 * Fixed fatal bug in failure packet handling. Server ignored
6809 the failure and thus crashed when it came.
6813 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6815 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6816 that the command may be executed only once in (about) 2 seconds.
6817 The old SILC_CF_LAG flag is same but allows command bursts up
6818 to five before limiting.
6820 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6821 server code. Various commands now includes the CF_LAG_STRICT
6822 flag to disallow any kind of miss-use of the command.
6824 * Fixed the silc_buffer_unformat to not to allocate any data
6825 if the length of the data is zero. It used to allocate the
6826 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6828 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6830 * Changed the format of AdminConnection configuration section
6831 in the server. Added username of the admin to the format.
6832 Affected files silcd/serverconfig.[ch].
6834 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6835 to return admin configuration data by host, username and/or
6838 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6840 * Implemented WHOWAS command to the server. Added the functions:
6842 silc_server_command_whowas_parse,
6843 silc_server_command_whowas_send_reply,
6844 silc_server_command_whowas_from_client and
6845 silc_server_command_whowas_from_server
6847 * Added <Client ID> argument to the WHOWAS command reply. Updated
6848 the protocol specs accordingly.
6850 * Implemented WHOWAS command and command_reply to the client
6853 Implemented the WHOWAS printing on the user interface.
6855 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6857 * Added new argument to the WHOWAS command reply, the real name.
6858 It is an optional argument. Updated the protocol specs.
6860 * Added SilcIDCacheDestructor callback that is registered when
6861 the SilcIDCache is allocated. The callback is called when
6862 an cache entry in the ID Cache expires, or is purged from the
6863 cache. Added into lib/silccore/idcache.[ch].
6865 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6866 to destruct the client entries when the cache entry expires.
6867 Other ID Cache's in server and in the client library ignores
6870 * If the ID Cache entry's `expire' field is zero then the entry
6871 never expires. Added boolean `expire' argument to the
6872 silc_idcache_add function in the lib/silccore/idcache.[ch].
6873 If it is TRUE the default expiry value is used.
6875 * Added silc_server_free_client_data_timeout that is registered
6876 when client disconnects. By default for 5 minutes we preserve
6877 the client entry for history - for WHOWAS command.
6879 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6881 * Added support to the server to enforce that commands are not
6882 executed more than once in 2 seconds. If server receives
6883 commands from client more frequently, timeout is registered
6884 to process the commands. Affected file silcd/command.c.
6885 Added new function silc_server_command_process_timeout.
6887 * Changed NICK_NOTIFY handling in client library to check that
6888 if the client's nickname was changed, so there is no need to
6889 resolve anything from the server.
6891 * Removed error printing from the WHOIS and IDENTIFY commands.
6892 If error occurs then it is ignored silently in the client library.
6893 The application, however, may map the received error to
6894 human readable error string. The application currently maps
6895 the NO_SUCH_NICKNAME error to string.
6897 * Made the command status message public to the application. Moved
6898 them from lib/silcclient/command_reply.c to
6899 lib/silcclient/command_reply.h. The application can map the
6900 received command status to the string with the
6901 silc_client_command_status_message function.
6903 * Added check to the server to check that client's ID is same
6904 as the Source ID in the packet the client sent. They must
6907 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6909 * Added dist-bzip hook to the Makefile.am to make bzip2
6910 compressed distributions.
6912 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6914 * Server now enforces the maximum length for the nickname and
6915 the channel as protocol specification dictates. 128 bytes for
6916 nickname and 256 bytes for channel name.
6918 * Moved the WHOIS printing to the application. The client libary
6919 does not print out the WHOIS information anymore, the application
6920 must do it. Renamed silc_client_command_reply_whois_print to
6921 the silc_client_command_reply_whois_save.
6923 The client's idle time is also sent to the application now, and
6924 the idle is shown on screen.
6926 * Added silc_client_command_reply_identify_save to save the
6927 received IDENTIFY entries.
6929 * Do not check for channel private keys in message sending and
6930 reception if the channel does not have the PRIVKEY mode set.
6931 Affected file lib/silclient/client_channel.c.
6933 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6935 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6936 just surfaced after chaning the JOIN procedure.
6938 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6940 * Added silc_client_get_clients_by_list to get client entries
6941 from Client ID list, that is returned for example by JOIN
6942 and USERS command replies. The application should use this
6943 function for example when JOIN command reply is received to
6944 resolve the clients already on the channel (library does not
6945 do that anymore as USERS command reply is not used in the JOIN
6946 procedure anymore). Affected files lib/silcclient/silcapi.h and
6947 lib/silcclient/idlist.c.
6949 * JOIN command reply and USERS command reply returns now SilcBuffer
6950 pointers instead of unsigned char pointers when returning
6951 the client list and mode list.
6953 * Added <Client ID> argument to the JOIN command reply, mainly
6954 for the server to identify for which client the command was
6955 originally sent. Updated protocol specs accordingly.
6957 * Added SilcDlist private_key pointer to the SilcChannelEntry
6958 in the client to support the channel private keys. Affected
6959 file is lib/silcclient/idlist.h.
6961 * Added SilcChannelPrivateKey argument to the function
6962 silc_client_send_channel_message so that application can choose
6963 to use specific private ke if it wants to. If it is not provided,
6964 the normal channel key is used, unless private keys are set.
6965 In this case the first (key that was added first) is used
6966 as the encryption key.
6968 * Implemented the support for channel private key handling.
6969 Implemented the following functions:
6971 silc_client_add_channel_private_key,
6972 silc_client_del_channel_private_keys,
6973 silc_client_del_channel_private_key,
6974 silc_client_list_channel_private_keys and
6975 silc_client_free_channel_private_keys
6977 Affected file lib/silcclient/client_channel.c.
6979 * Added the support for the private keys in the channel message
6980 sending and encryption and in the message reception and
6981 decryption. Affected funtions are
6982 silc_client_send_channel_message and silc_client_channel_message.
6984 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6986 * Added SKE's key verify callback to the client library's
6987 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6989 * Removed the statement that server (or router) must send USERS
6990 command reply when joining to the channel so that the client
6991 knows who are on the channel. Instead, the client list and
6992 client's mode list is now sent in the JOIN command reply to the
6993 client who joined channel. This is better solution.
6995 * Added function silc_server_get_users_on_channel and function
6996 silc_server_save_users_on_channel to the silcd/server.[ch].
6998 * Removed function silc_server_command_send_users from the
7001 * Do not show topic on the client library anymore. The topic is
7002 sent in the command reply notify to the application and the
7003 application must show the topic now.
7005 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7007 * Added client searching by nickname hash into the IDENTIFY and
7008 WHOIS commands in the server as they were clearly missing from
7009 them. Affected file is silcd/command.c.
7011 * Fixed a bug in private message receiving in the client library.
7012 The remote ID was freed and it wasn't supposed, now it is
7015 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7017 * Minor fix to the channel payload; allocate the data area, as it
7018 needs to be of specific length.
7020 * If the key agreement port is zero then the operating
7021 system will define the bound port. Affected files are
7022 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7024 * Added new function silc_channel_payload_decrypt into the file
7025 lib/silccore/silcchannel.[ch].
7027 * Moved the channel message etc, check from silc_packet_decrypt
7028 to applications. The library calls now a generic
7029 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7030 when the packet is either normal or special. This was done to
7031 allow more wide range of checking that was not allowed when
7032 the code was in library. Now applications can do virtually any
7033 checks to the packet and return to the library the decision how
7034 the packet should be processed. Affected files are
7035 lib/silccore/silcpacket.[ch].
7037 Added silc_server_packet_decrypt_check to the server and
7038 silc_client_packet_decrypt_check to the client library.
7040 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7041 to send with specified source and destination information.
7043 * Channel message delivery between routers was broken after the
7044 channel key distribution was fixed earlier. The channel key
7045 was used be to distributed to other routers as well which is not
7046 allowed by the protocol. Now this is fixed and channel keys
7047 really are cell specific and the channel message delivery between
7048 routers comply with the protocol specification.
7050 * Fixed various commands in server to check also the global list
7051 for the channel entry and not just the local list. The affected
7052 file silcd/command.c.
7054 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7056 * Added assert()s to buffer formatting and unformatting routines
7057 to assert (if --enable-debug) when error occurs. Affected
7058 file: lib/silcutil/silcbuffmt.c.
7060 * Changed to auto-reconnect to check whether the remote host is
7061 router and register the re-connect timeout if it is. It used
7062 to check that whether we are normal server, but router must do
7063 auto-reconnect with another router as well. Affected file
7066 * Removed the [<key len>] option from CMODE command as the cipher
7067 name decides the key length, nowadays. See the defined ciphers
7068 from the protocol specification.
7070 * Added [<hmac>] option to the CMODE command to define the HMAC
7071 for the channel. Added SILC_CMODE_HMAC channel mode.
7073 * Added [<hmac>] option for the JOIN command so that user can
7074 select which HMAC is used to compute the MACs of the channel
7077 * Added Hmac field to the Channel Message Payload. The integrity
7078 of plaintext channel messages are now protected by computing
7079 MAC of the message and attaching the MAC to the payload. The
7080 MAC is encrypted. Now, it is clear that this causes some
7081 overhead to the size of the packet but rationale for this is that
7082 now the receiver can verify whether the channel message decrypted
7083 correctly and also when private keys are set for the channel the
7084 receiver can decrypt the packet with several keys and check from
7085 the MAC which key decrypted the message correctly.
7087 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7088 lib/silccrypt/silccipher.[ch].
7090 * Added silc_hash_len to return the digest length into the
7091 lib/silcrypt/silchash.[ch].
7093 * Rewrote parts of Silc Channel Payload interface in the
7094 lib/silccore/silcchannel.[ch]. The encode function now also
7095 encrypts the packet and parse function decrypts it.
7097 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7099 * Fixed a minor formatting bug in the SKE's key material processing.
7100 It actually might have processed the keys wrong way resulting
7103 * Redefined the mandatory HMAC algorithms and added new algorithms.
7104 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7105 and hmac-md5 truncated to 96 bits. The mandatory is now
7106 hmac-sha1-96. Rest are optional (including the one that used
7107 to be mandatory). Rationale for this is that the truncated HMAC
7108 length is sufficient from security point of view and can actually
7109 make the attack against the HMAC harder. Also, the truncated
7110 HMAC causes less overhead to the packets. See the RFC2104 for
7113 * Added new [hmac] configuration section. The SKE used to use
7114 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7115 is of course wrong. The official names that must be proposed in
7116 the SKE are the ones defined in the protocol specification
7117 (hmac-sha1-96 for example). The user can configure any hmac
7118 using any hash function configured in the [hash] section. At
7119 least, the mandatory must be configured.
7121 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7123 * Added HMAC list to the SKE proposal list. It has now both
7124 hash algorithm list and HMAC list. This makes the protocol
7125 incompatible with previous versions. The SKE now seems to work
7126 the way it is supposed to work, for the first time actually.
7128 * Defined plain Hash algorithms to the protocol specification.
7131 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7133 * Implemented support for key agreement packets into the server.
7134 Added functions silc_server_key_agreement and
7135 silc_server_send_key_agreement. Other than these functions,
7136 server has nothing to do with this packet.
7138 * Added support for private message key packets into the server.
7139 Added functions silc_server_private_message_key and
7140 silc_server_send_private_message_key.
7144 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7145 called in the protocol's final callback instead in the END
7146 protocol state. This makes a little more sense and in the same
7147 time in client we can use the same protocol routines for normal
7148 key exchange and to key agreement packet handling as well.
7150 * Added to both client's and server's KE protocol context the
7151 SilcSKEKeyMaterial pointer to save the key material. We will
7152 bring the key material to the protocol's final callback by doing
7153 this. The final callback must free the key material.
7155 * Added SKE's packet_send callback into client's KE protocol
7156 context so that the caller can choose what packet sending function
7157 is used. This way we can use different packet sending when
7158 doing normal SKE when doing key agreement packet handling (in
7159 the key agreement packet handling we do not want to encrypt
7162 * Implemented the responder side of the key agreement routines
7163 in the client. The client can now bind to specified port and
7164 accept incoming key negotiation. The key material is passed
7165 to the application after the protocol is over.
7167 * Implemented the processing of incoming Key Agreement packet
7168 in the client. Added function silc_client_key_agreement to
7171 * Implemented the intiator side of the key agreement routines
7172 in the client. The client can now initiate key agreement with
7173 another remote client. The key material is passed to the
7174 application after the protocol is over.
7176 * Created client_keyagr.c to include all the key agreement
7179 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7180 SILC_TASK_CALLBACK except that it is not static.
7182 * Created client_notify.c and moved the Notify packet handling
7183 from the client.[ch] into that file.
7185 * Created client_prvmsg.c and moved all private message and
7186 private message key routines from the client.[ch] into that file.
7188 * Create client_channel.c and moved all channel message and
7189 channel private key routines from the client.[ch] into that file.
7191 * Changed silc_client_get_client_by_id_resolve to resolve with
7192 WHOIS command instead of IDENTIFY command, in the file
7193 lib/silclient/idlist.c.
7195 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7197 * Implemented the SKE's responder side to the Client library.
7199 * When FAILURE is received to the protocol do not trust it
7200 blindly. Register a timeout to wait whether the remote closes
7201 the connection as it should do it, only after that process the
7202 actual failure. This was changed to both client and server.
7204 * Added client_internal.h to include some of the structures
7205 there instead of client.h in lib/silcclient/.
7207 * Added function silc_task_unregister_by_callback to unregister
7208 timeouts by the callback function.
7210 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7212 * Some "Incomplete WHOIS info" errors has been appearing on the
7213 log files. Took away the entry->userinfo check from WHOIS
7214 reply sending. The entry->userinfo is now " " if client did not
7215 provide one. I thought this was fixed earlier but something
7216 is wrong still. Let's see if the error still appears.
7218 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7220 * Fixed a minor bug in the login when the channel key is
7221 re-generated in the server. It used to generate the key in
7222 wrong order and thus caused problems in the channel traffic.
7224 * Fixed a minor bug in channel key distsribution after
7225 KICK command. The key was not sent to the router even though
7228 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7230 * Added silc_ske_process_key_material_data as generic routine
7231 to process any key material as the SILC protocol dictates. The
7232 function is used by the actual SKE library but can be used by
7233 applications as well. This relates to the private message keys
7234 and the channel private keys since they must be processed the
7235 same way the normal SILC session keys. The protocol dictates
7236 this. Affected files: lib/silcske/silcske.[ch].
7238 Added also silc_ske_free_key_material to free the
7239 SilcSKEKeyMaterial structure.
7241 * Defined silc_cipher_set_key function to set the key for
7242 cipher without using the object's method function. The affected
7243 files: lib/silccrypt/silccipher.[ch].
7245 * Implemented silc silc_client_add_private_message_key,
7246 silc_client_add_private_message_key_ske,
7247 silc_client_del_private_message_key,
7248 silc_client_list_private_message_keys and
7249 silc_client_free_private_message_keys functions in the
7252 Added functions silc_client_send_private_message_key to send
7253 the Private Message Key payload and silc_client_private_message_key
7254 to handle incoming Private Message Key payload.
7256 * Added Cipher field to the Private Message Key payload to set
7257 the cipher to be used. If ignored, the default cipher defined
7258 in the SILC protocol (aes-256-cbc) is used.
7260 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7262 * Removed lib/silcclient/ops.h file.
7264 Redefined parts of the SILC Client Library API. Created new
7265 file silcapi.h that deprecates the ops.h file and defines the
7266 published Client Library API. Defined also private message key
7267 API and channel private key API into the file.
7269 This is the file that the application must include from the
7270 SILC Client Library. Other files need not be included by
7271 the application anymore.
7273 * Added new key_agreement client operation callback and also
7274 defined the Key Agreement library API for the application.
7276 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7278 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7279 is used by clients to request key negotiation between another
7280 client in the SILC network. If the negotiation is started it
7281 is performed using the SKE protocol. The result of the
7282 negotiation, the secret key material, can be used for example
7283 as private message key.
7285 Implemented the Key Agreement payload into the files
7286 lib/silccore/silauth.[ch].
7288 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7290 * Redefined ciphers for the SILC protocol. Added some new ciphers
7291 and defined the key lengths for the algorithms. Changed the
7292 code accordingly. The default key length is now 256 bits.
7294 * Fixed SKE key distribution function silc_ske_process_key_material
7295 when the key length is more than 128 bits. The default key
7296 length in SILC is now 256 bits.
7298 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7299 to indicate unsupported algorithm.
7301 * Renamed rijndael.c to aes.c and all functions as well.
7303 * Fixed a long standing channel key setting bug in client library.
7304 Weird that it has never surfaced before.
7306 * Fixed bug in channel deletion. If the entire channel is removed
7307 then it must also delete the references of the channel entry
7308 from the client's channel list as the client's channel entry and
7309 the channel's client entry share same memory.
7311 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7313 * Implemented CONNECT and SHUTDOWN commands in the client.
7315 * Implemented CLOSE command to the client.
7317 * Added the function silc_idlist_find_server_by_name into the
7318 files silcd/idlist.[ch].
7320 Added the function silc_idlist_find_server_by_conn into the
7321 files silcd/idlist.[ch].
7323 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7325 * DIE command was renamed to SHUTDOWN. Updated the both code
7328 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7329 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7331 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7334 * Added function silc_server_create_connection function to create
7335 connection to remote router. My server implementation actually
7336 does not allow router to connect to normal server (it expects
7337 that normal server always initiates the connection to the router)
7338 so the CONNECT command is only good for connecting to another
7341 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7343 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7344 or some other client was kicked from the channel.
7346 Implemented the handling of the notify type to both client
7349 Implemented silc_server_send_notify_kicked to send the KICKED
7350 notify. It is used to send it to the server's primary router.
7352 * Implemented the KICK command into server and client.
7354 * Added `query' argument to the silc_idlist_get_client function
7355 to indicate whether to query the client from server or not if
7358 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7359 to indicate that the client is not channel founder.
7363 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7365 * Removed the rng context from SilcPacketContext structure and
7366 changed that the packet routine uses the Global RNG API.
7368 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7370 * Added support for quit message that client can "leave" on the
7371 channel when it quits the SILC. It is ditributed inside the
7372 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7374 Added silc_server_free_client_data that will take the
7375 signoff message as argument.
7377 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7379 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7381 * Updated parts of the protocol specification to keep it up
7384 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7386 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7387 payloads in one packet.
7389 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7390 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7391 use now the new List flag.
7393 * Also deprecated the following packet types: REPLACE_ID,
7394 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7396 * Added list support for Notify packet in server.
7398 * Added silc_server_send_notify_channel_change to send the
7399 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7400 the silc_server_send_replace_id.
7402 * Added silc_server_send_notify_nick_change to send the
7403 NICK_CHANGE notify type. Deprecates the function
7404 silc_server_send_replace_id.
7406 * Added silc_server_send_notify_join to send the JOIN notify type.
7407 Deprecates the function silc_server_send_new_channel_user.
7409 * Added silc_server_send_notify_leave to send LEAVE notify type.
7410 Deprecates the function silc_server_send_remove_channel_user.
7412 * Added silc_server_send_notify_cmode and
7413 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7414 types. Deprecates the silc_server_send_set_mode function.
7416 * Added SERVER_SIGNOFF notify type to indicate that server has
7417 quit. This means that all clients on the channel from that
7418 server will drop. This can be also used when netsplit happens.
7420 Deprecated REMOVE_ID packet type since it is not needed anymore
7423 Added silc_server_send_notify_server_signoff to send the
7424 SERVER_SIGNOFF notify type. Deprecates the function
7425 silc_server_send_remove_id.
7427 Added also silc_server_send_notify_signoff to send the
7428 SIGNOFF notify type.
7430 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7431 SILC protocol from this day on. Changed the protocol
7432 specification as well.
7434 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7435 notify type. It is used between routers to notify about
7436 topic changes on a channel.
7438 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7441 * Partly updated the protocol specification to comply with the
7442 changes now made. It is still though a bit outdated.
7444 * The JOIN notify type now takes one extra argument <Channel ID>.
7445 The packet used to be destined to the channel but now the
7446 JOIN type may be sent as list thus it is impossible to
7447 destine it to any specific channel. By adding this argument
7448 it is again possible.
7450 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7452 * Added CREDITS file. The CHANGES and CREDITS file will appear
7453 in the distribution as well.
7455 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7457 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7458 types in the server's silcd/packet_receive.c.
7460 * Implemented CMODE and CUMODE to work in router environment.
7462 * Fixed minor encoding and decoding buglet from the
7463 lib/silccore/silcmode.c.
7465 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7468 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7470 * Changed all SilcConfigServer* and silc_config_server* to
7471 SilcServerConfig* and silc_server_config*, respectively.
7474 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7476 * Associated the ID (client or server ID) to the Authentication
7477 Payload to avoid any possibility of forging. Updated the
7478 protocol specification and the code accordingly.
7480 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7482 * The RSA key length is now save to the RsaKey context in the
7483 key generation process in lib/silccrypt/rsa.c. The key length
7484 is now used to figure out the maximum size of the block allowed
7485 to be encrypted/signed.
7487 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7488 is equivalent to the silc_mp_mp2bin but does not allocate any
7491 * Changed silc_mp_mp2bin API to take length argument. If it is
7492 non-zero then the buffer is allocated that large. If zero, then
7493 the size is approximated using silc_mp_sizeinbase, which however
7496 * Created Global RNG API which is global RNG that application can
7497 initialize. After initializing, any routine anywhere in the
7498 code (including library) can use RNG without allocating a new
7499 RNG object. This was done to allow this sort of use of the
7500 RNG in code that has no chance to allocate RNG object. All
7501 applications currently allocate this and many routines in the
7502 library use this. Affected file lib/silccrypt/silcrng.[ch].
7504 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7505 it to use the Global RNG API.
7507 * Defined Authentication Payload into protocol specification that
7508 is used during SILC session to authenticate entities. It is
7509 used for example by client to authenticate itself to the server
7510 to obtain server operator privileges.
7512 Implemented this payload into the lib/silccore/silcauth.[ch].
7513 Implemented also routines for public key based authentication
7514 as the new protocol specification dictates.
7516 Moved definitions of different authentication methods from
7517 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7519 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7520 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7521 silc_pkcs_verify_with_hash functions into the file
7522 lib/silccrypt/silcpkcs.[ch].
7524 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7526 * The client entry's userinfo pointer must be always valid.
7527 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7528 will fail since it requires the userinfo. Now, the userinfo
7529 is allocated as "" if actual userinfo does not exist. Actually,
7530 it must exist and it is totally Ok to drop client connections
7531 that does not announce the userinfo. However, we will make
7532 this workaround for now.
7534 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7535 to return the remote port by socket.
7537 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7539 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7540 SILC_SERVER_PENDING_EXEC and added an new macro
7541 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7542 data or when error occurs while processing the pending command.
7544 Added new argument `destructor' into silc_server_command_pending
7545 and to the SilcServerCommandPending object. This destructor is
7546 now called after calling the pending callback or if error occurs
7547 immediately. If error occurs the actual pending callback won't
7548 be called at all - only the destructor. The destructor may be
7549 NULL if destructor is not needed.
7551 All this applies for client library code as well. Similar
7552 changes were made there as well for the pending commands.
7554 In the client, the application must now allocate the
7555 SilcClientCommandContext with the silc_client_command_alloc
7558 * Added reference counter to the SilcServerCommandContext. Added
7559 function silc_server_command_alloc and silc_server_command_dup
7562 Same type of functions added to the client library for the same
7565 * Removed the cmd_ident from IDListData away since it is now
7566 global for all connections. It is the command identifier used
7567 in command sending and with pending commands. The affected file
7570 * Added reference counter to the SilcSocketConnection objecet to
7571 indicate the usage count of the object. The object won't be
7572 freed untill the reference counter hits zero. Currently only
7573 server uses this, and client ignores it. The client must be
7574 set to use this too later. The affected files are
7575 lib/silccore/silcsockconn.[ch]. Added also the function
7576 silc_socket_dup to increase the reference counter.
7578 This was mainly added because it is possible that the socket
7579 is removed underneath of pending command or other async
7580 operation. Now it won't be free'd and proper DISCONNECTING
7581 flags, etc. can be set to avoid sending data to connection that
7582 is not valid anymore.
7584 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7585 the connection. After that it sets SILC_SET_DISCONNECTED.
7586 It is, however, possible that the socket data is not still freed.
7587 The silc_server_packet_process now checks that data is not
7588 read or written to connection that is DISCONNECTED. The socket
7589 get's freed when the reference counter hits zero.
7591 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7593 * Changed the client operation API: channel_message operation's
7594 `sender' is now the client entry of the sender, not the nickname
7595 and the `channel' is the channel entry, not the channel name.
7597 In the private_message operation the `sender' is now also the
7598 client entry of the sender not the nickname.
7600 Affected file is lib/silcclient/ops.h and all applications
7601 using the client operations.
7603 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7605 * Moved the calling of ops->connect() from connect_to_server_final
7606 into receive_new_id functin since that is the point when the
7607 client is actually allowed to send traffic to network. The
7608 affected file is lib/silcclient/client.c.
7610 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7612 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7613 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7614 (if needs broadcasting) instead of broadcasting the packets one
7615 by one which would make a burst in the network traffic.
7617 * Added `broadcast' argument to the functions in silcd/server.[ch]
7618 silc_server_create_new_channel[_with_id] to indicate whether
7619 to send New Channel packet to primary router.
7621 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7623 * Added new function into the silcd/server.[ch] files:
7624 silc_server_create_new_channel_with_id to create new channel with
7625 already existing Channel ID.
7627 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7628 lib/silccore/silcpacket.h. This packet is used t send list of
7629 Set Mode payloads inside one packet. Server uses this to set
7630 the modes for the channels and clients on those channels, that it
7631 announced to the router when it connected to it. The protocol
7632 specification has been updated accordingly.
7634 * The silc_server_new_channel did not handle the packet coming
7635 from normal server as it normally does not send that. However,
7636 when it announces its channels it does send it. Implemented
7637 the support for that.
7639 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7640 into the file lib/silccore/id.h.
7642 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7644 * Fixed memory leaks in the functions silc_idlist_del_client,
7645 silc_idlist_del_channel and silc_idlist_del_server in the file
7646 silcd/idlist.c. All of those leaked like a sieve.
7648 * Fixed some small memory leaks in the client's function
7649 silc_client_notify_by_server.
7651 * Added functions into silcd/server.c: silc_server_announce_clients,
7652 silc_server_announce_channels and silc_server_announce_server.
7653 These functions are used by normal and router server to announce
7654 to its primary router about clients, channels and servers (when
7655 router) that we own. This is done after we've connected to the
7658 These functions effectively implements the following packet types:
7659 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7660 and SILC_PACKET_NEW_ID_LIST.
7662 * Added new functions into the silcd/packet_receive.[ch]:
7663 silc_server_new_id_list, silc_server_new_channel_list and
7664 silc_server_new_channel_user_list to handle the incoming
7665 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7667 * Added support of changing Channel ID in the function
7668 silc_server_replace_id. If the server that announces a channel
7669 to the router already exists in the router (with same name but
7670 with different Channel ID), router is responsible to send
7671 Replace ID packet to the server and force the server to change
7672 the Channel ID to the one router has.
7674 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7675 client that the Channel ID has been changed by the router. The
7676 normal server sends this to the client. Client must start using
7677 the new Channel ID as the channel's ID.
7679 Implemented handling of this new type into lib/silcclient/client.c
7680 into the function silc_client_notify_by_server.
7682 * Added new function silc_idlist_replace_channel_id into the files
7683 silcd/idlist.[ch] to replace the Channel ID.
7685 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7687 * Call silc_server_command_identify_check always when processing
7688 the IDENTIFY command in silcd/command.c
7690 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7692 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7693 send keepalive packets. The packet can be sent by clients,
7694 servers and routers.
7696 Added function silc_socket_set_heartbeat into the file
7697 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7698 If not set, the heartbeat is not performed. The actual
7699 heartbeat is implemented in the low level socket connection
7700 library. However, application is responsible of actually
7703 Added silc_server_send_heartbeat to send the actual heartbeat
7704 packet into silcd/packet_send.[ch]. Server now performs
7705 keepalive with all connections.
7707 * Added silc_task_get_first function into lib/silcutil/silctask.c
7708 to return the timeout task with shortest timeout. There was a bug
7709 in task unregistration that caused problems. TODO has been
7710 updated to include that task system must be rewritten.
7712 * The client library will now resolve the client information when
7713 receiving JOIN notify from server for client that we know but
7714 have incomplete information.
7716 * Rewrote parts of silc_server_remove_from_channels and
7717 silc_server_remove_from_one_channel as they did not remove the
7718 channel in some circumstances even though they should've.
7720 * Encryption problem encountered in server:
7722 The LEAVE command used to send the Channel Key packet to the
7723 router immediately after generating it. However, the code
7724 had earlier sent Remove Channel user packet but not immediately,
7725 ie. it was put to queue. The order of packets in the router
7726 was that Channel Key packet was first and Remove Channel User
7727 packet was second, even though they were encrypted in the
7728 reverse order. For this reason, MAC check failed. Now, this
7729 is fixed by not sending the Channel Key packet immediately but
7730 putting it to queue. However, this is more fundamental problem:
7731 packets that are in queue should actually not be encrypted
7732 because packets that are sent immediately gets encrypted
7733 actually with wrong IV (and thus MAC check fails). So, packets
7734 that are in queue should be encrypted when they are sent to
7735 the wire and not when they put to the queue.
7737 However, the problem is that the current system has not been
7738 designed to work that way. Instead, the packet is encrypted
7739 as soon as possible and left to the queue. The queue is then
7740 just purged into wire. There won't be any fixes for this
7741 any time soon. So, the current semantic for packet sending
7744 o If you send packet to remote host and do not force the send
7745 (the packet will be in queue) then all subsequent packets to the
7746 same remote host must also be put to the queue. Only after the
7747 queue has been purged is it safe again to force the packet
7750 o If you send all packets immediately then it safe to send
7751 any of subsequent packets through the queue, however, after
7752 the first packet is put to queue then any subsequent packets
7753 must also be put to the queue.
7755 Follow these rules and everything works fine.
7757 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7759 * Added new function silc_server_remove_clients_by_server to
7760 remove all client entries from ID list when the server connection
7761 is lost. In this case it is also important to invalidate all
7762 client entires as they hold the invalid server entry. This
7763 fixes fatal bug when server has lost connection and will reconnect
7766 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7768 * Made some sanity checks to silc_server_daemonise like to check
7769 whether the requested user and group actually exists.
7771 * Added sanity check to SKE's silc_ske_responder_finish to check
7772 that the public and private key actually is valid.
7774 * Invalidate the client's nickname when receiving Replace ID
7775 packet and the Client ID is being replaced. This means that the
7776 server will query the nickname if someone needs it (client)
7779 * Sort the ID Cache in client library when the ID Cache data
7780 has changed (needs sorting).
7782 * Do not allow for SILC client to create several connections to
7783 several servers. The client does not support windows right now
7784 and generating multiple connections causes weird behaviour.
7786 Irssi-silc client does support windows and can handle several
7787 connections without problems, see: www.irssi.org and SILC plugin.
7789 * Fixed some places where client was added to the IDList. The
7790 rule of thumb is following (in order to get everything right):
7791 If the client is directly connected local client then the
7792 `connection' argument must be set and `router' argument must be
7793 NULL to silc_idlist_add_client function. If the client is not
7794 directly connected client then the `router' argument must
7795 bet set and the `connection' argument must be NULL to the
7796 silc_idlist_add_client function.
7798 * The funtion silc_server_packet_send_local_channel actually did
7799 not check whether the client was locally connected or not. It
7800 does that now. Fixed a bug related to LEAVE command.
7802 * Fixed Remove Channel User payload parsing bug in server's
7803 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7805 * The server's silc_server_save_channel_key now checks also the
7806 global ID list for the channel as it might not be in the local
7807 list. Fixed a bug related to LEAVE command.
7809 * Is this the end of the [<unknown>] buglet that has been lurking
7810 around for a long time? A little for loop fix in server's
7811 silc_server_command_whois_parse that is used by both IDENTIFY
7812 and WHOIS command. At least, this was a clear bug and a cause
7813 of one type of [<unknown>] buglet.
7815 * WHOIS and IDENTIFY commands call the function
7816 silc_server_command_[whois/identify]_check function even if
7817 we are not router server.
7819 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7821 * Added --with-gmp configuration option. If set the GMP
7822 is always compiled in the SILC source tree. If not set then
7823 it is checked whether the system has the GMP3 installed. If
7824 it has then the GMP won't be compiled (the system's headers
7825 and library is used), if it doesn't have it then the GMP is
7826 compiled in the SILC source tree.
7828 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7830 * Changed RSA private exponent generation to what PKCS #1
7831 suggests. We try to find the smallest possible d by doing
7832 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7833 not security fix but optimization.
7835 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7837 * Added new config entry [Identity] to fork the server and run
7838 it as specific user and group. A patch from Bostik.
7840 * Imported Dotconf configuration library into lib/dotconf.
7841 This will be used to create the SILC configuration files later.
7842 It will appear in the distsribution after this commit.
7844 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7846 * A big code auditing weekend happening. Auditing code for
7847 obvious mistakes, bugs and errors. Also, removing any code
7850 Removed files for being obsolete:
7852 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7853 inline in the file lib/silcutil/silcbuffer.h)
7855 o lib/silcutil/silcbufutil.c (the header has inline versions)
7857 Changed code to fix possible error conditions:
7859 o The buffer formatting routines now check that the destination
7860 buffer really has enough space to add the data. This applies for
7861 both buffer formatting and unformatting
7862 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7863 unformatting was changed to accomodate following rules:
7864 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7865 sent to the function while XXX_*STRING will not allocate or copy
7866 the data into the buffer. Instead it sets the pointer from the
7867 buffer into the pointer sent as argument (XXX_*STRING used to
7868 require that the pointer must be allocated already). This change
7869 makes this whole thing a bit more consistent and more optimized
7870 (note that the data returned in the unformatting with XXX_*STRING
7871 must not be freed now). The routines return now -1 on error.
7873 o Tried to find all code that use buffer_format and buffer_unformat
7874 and added return value checking to prevent formatting and
7875 especially unformatting errors and possible subsequent fatal
7878 o Changed ske->x and ske->KEY to mallocated pointers in
7879 lib/silcske/silcske.h. Fixed possible data and memory leak.
7881 o Added return value checking to all *_parse* functions. Fixed
7882 many memory leaks as well.
7884 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7885 so that buffer overflows would not happen. All code now also
7886 checks the return value as it can fail.
7888 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7890 * Added reconnection support to server if the normal server looses
7891 its connection to the router (for example if router is rebooted).
7892 The server performs normal reconnection strategy implemented
7893 to the server. Affected file silcd/server.c.
7895 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7897 * Added new packet type SILC_PACKET_SET_MODE that is used to
7898 distribute the information about changed modes (for clients,
7899 channels and clients channel modes) to all routers in the
7900 network. Updated the protocol specification accordingly.
7902 Added functions into silcd/packet_send.c and
7903 silcd/packet_receive.c: silc_server_send_set_mode,
7904 silc_server_set_mode.
7906 Added new files silcmode.[ch] into lib/silccore that implements
7907 the encoding and decoding of Set Mode Payload. Added new type
7908 SilcSetModePayload. Moved the definitions of different modes
7909 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7911 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7913 * Oops, a little mistake in server's connection authentication
7914 protocol. The protocol is not ended with FAILURE but with
7915 SUCCESS if the authentication is Ok. :) Affected file is
7918 * Implemented NICK_CHANGE notify handling in server in the file
7919 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7920 the local clients on the channel. After the changing nickname
7921 in router environment snhould work and the [<unknown>] nickname
7922 should appear no more.
7924 The silc_server_replace_id function that receives the Replace ID
7925 payload now sends the NICK_CHANGE notify type also in the file
7926 silcd/packet_receive.c
7928 * Changed WHOIS and IDENTIFY command to support the maximum amount
7929 of arguments defined in protocol specs (3328 arguments). This
7930 fixed a bug that caused problems when there were more than three
7933 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7935 * Added extra parameter, command identifier, to the
7936 silc_client_send_command so that explicit command identifier
7939 Changed that ID list routines uses specific command identifier
7940 when sending WHOIS/IDENTIFY requests to the server so that they
7941 can be identified when the reply comes back.
7943 Affected files lib/silcclient/command.[ch],
7944 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7946 * Added `sender' argument to silc_server_packet_send_to_channel
7947 to indicaet the sender who originally sent the packet to us
7948 that we are now re-sending. Ignored if NULL. Affected file
7949 silcd/packet_send.[ch].
7951 * Added some server statistics support in silcd/server_internal.h
7952 SilcServerStatistics structure and around the server code. Also
7953 send some nice statistics information when client is connecting
7956 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7958 * Fixed channel ID decoding in server's JOIN command reply in
7959 silcd/command_reply.c
7961 * Fixed braodcasting of replace ID payload to not to send it if
7962 we are standalone server in silcd/packet_receive.c.
7964 * Fixed all channel message sending routines to not to send
7965 packets to clients that has router set, since they are routed
7966 separately in the same function earlier. Affects file
7967 silcd/packet_send.c and all channel packet sending functions.
7969 * In USERS reply, res_argv[i] are not allocated, the table
7970 is allocated. Thus changed that free the table, not its
7973 * In server's whois_check and identify_check if the client is
7974 locally connected do not send any WHOIS commands - they are not
7977 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7979 * Fixed some minor bugs in client when sending WHOIS command. The
7980 arguments was in wrong order.
7982 * Removed statis function add_to_channel from server in
7983 silcd/command.c that was previously used with the joining but
7986 * Tested USERS command in router environment successfully with two
7987 routers, two servers and two clients.
7989 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7991 * Reorganized the USERS command and command reply in client library
7992 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7993 When the command is given by user we register a pending command
7994 callback that will reprocess the command after the reply has been
7995 received from the server. When reprocessing the packet we then
7996 display the information. Thus, the USERS information is displayed
7997 now in the command callback instead of in the command reply
7998 callback. The processing of the command is same as previously
7999 when server has sent the command reply in the JOINing process.
8001 * Added to USERS command in silcd/command_reply.c to join the client,
8002 we didn't use to know about, to the channel after we've created
8003 a client entry for it. Also, for clienet we did know already still
8004 check whether it is on the channel or not and add it if not.
8006 * Removed silc_server_command_join_notify as the function and its
8009 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8011 * Changed the client's pending command handling to the same as the
8012 server's pending command handling. It is also now possible to
8013 execute command reply functions from other command reply
8014 function as the function callbacks for commands and command
8015 replies are one and same. The pending commands are not static
8016 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8017 in client connection context. Thus, pending commands are server
8018 connection specific as it is convenient.
8020 Changed the function silc_client_command_pending and
8021 silc_client_command_pending_del and added new function
8022 silc_client_command_pending_check. Removed the
8023 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8026 * Added cmd_ident, current command identifier, to the client
8027 connection context in lib/silcclient/client.h to keep track on
8028 command identifiers used in command sending. Client's command reply
8029 function handling now supports the mandatory command identifiers.
8031 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8032 funtions in client to fully support pending command callbacks.
8034 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8035 as one of the arguments to the application in the command reply
8038 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8039 before first releasing SILC but came back. Now it is removed again
8040 and should come back nomore. The FORWARDED flag was used only
8041 by the JOINing procedure by forwarding the command packet to router.
8042 Now, the JOINing procedure has been changed to more generic (due
8043 to various router environment issues) and FORWARDED is not needed
8044 anymore for anything. The protocol specification is yet to be
8047 Now, removed silc_server_packet_forward from server and the flag
8048 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8050 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8052 * Renamed NAMES command to USERS command. The NAMES was named that
8053 due to historical reasons. Now it is renamed. Also, rewrote
8054 parts of the USERS command. The nickname list is not sent anymore
8055 by the server. Only Client ID and mode lists are sent in the USERS
8056 command. Changed this also to the protocol specification.
8058 The client now resolves the names and stuff after it receives
8059 the USERS list from the server when joining to the channel.
8061 * WHOIS and IDENTIFY commands has been changed to support multiple
8062 Client ID's per command. One can now search for multiple users
8063 in the network by sending only one WHOIS or IDENTIFY command.
8064 Changed the code and the protocol specifications.
8066 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8067 uses silc_server_command_whois_parse to parse the request. */
8069 * If normal server, do not parse the WHOIS and IDENTIFY requests
8070 before sending it to the router. Saves some time.
8072 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8074 * Fixed JOIN command on client library. Wrong number of arguments
8075 used to crash the client.
8077 * Added silc_server_channel_has_global function to check whether
8078 channel has global users or not.
8080 * Added silc_server_channel_has_local function to check whether channel
8081 has locally connected clients on the channel.
8083 * The silc_server_remove_from_one_channel now checks whether the
8084 channel has global users or not after given client was removed from
8085 the channel. It also checks whether the channel has local clients
8086 on the channel anymore. If it does not have then the channel entry
8087 is removed as it is not needed anymore.
8089 * The silc_server_notify now checks on JOIN notify whether the joining
8090 client is one of locally connected or global. If it is global then
8091 the channel has now global users on the channel and that is marked
8092 to the channel entry. Also, it now saves the global client to
8093 global list who is joining and JOINs it to the channel. This is
8094 for normal server, that is.
8096 Changed silc_server_send_notify_on_channel,
8097 silc_server_packet_relay_to_channel and
8098 silc_server_packet_send_to_channel check if we are normal server
8099 and client has router set (ie. global client) do not send the
8100 message to that client, as it is already routed to our router.
8102 * Implemented LEAVE notify type handling in silc_server_notify
8105 * Tested LEAVE command in router environment successfully. Tested
8106 with two routers, two servers and two clients.
8110 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8112 * Implemented SIGNOFF notify type handling in silc_server_notify
8115 * silc_server_remove_id now removes the client entry from all channels
8116 it has joined and thusly sends SIGNOFF notify type.
8118 * Rewrote the NAMES list generation in server by removing two excess
8119 loops. The lists are created now inside one loop.
8121 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8123 * silc_server_remove_channel_user checks now also global list
8124 for channel and client.
8126 * silc_server_new_channel_user checks now both local and global
8127 list for channel and client. Fixed a bug in client id decoding.
8128 Used to decode wrong buffer.
8130 * silc_server_channel_message checks now both local and global
8131 list for channel entry.
8133 * Tested channel joining (hence JOIN) in router environment
8134 successfully. Tested with two routers, two servers and two
8137 * Tested channel message sending in router environment successfully.
8139 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8141 * Added silc_server_save_channel_key into server.[ch] to save the
8142 received channel key in Channel Key payload processing. It is
8143 also used in JOIN command reply handling.
8145 Equivalent function silc_client_save_channel_key added into
8146 client.[ch] into client library.
8148 * Changed JOIN command reply to send information whether the channel
8149 was created or not (is existing already) and the channel key
8150 payload. Changed protocol specs accordingly.
8152 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8153 the request was sent by ID and not by nickname. Crashed on
8156 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8158 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8159 now correctly save the received data.
8161 * silc_server_free_sock_user_data now notifies routers in the
8162 network about entities leaving the network.
8164 At the same time implemented functions silc_server_remove_id
8165 and silc_server_send_remove_id to receive and send REMOVE_ID
8166 packets. The packet is used to notify routers in the network
8167 about leaving entities. The ID removed will become invalid in
8170 * Added function silc_idlist_del_server into server. Removes and
8171 free's server entry from ID list.
8173 * silc_server_private_message function now checks, if we are router,
8174 that the destination ID really is valid ID, naturally.
8176 * In router when NEW_ID packet is received (for new client) the
8177 hash of the Client ID is saved in the ID Cache but the
8178 client->nickname is set to NULL, instead of putting the hash
8181 IDENTIFY command now also checks that client->nickname must be
8182 valid. If it is not if will request the data from the server who
8183 owns the client. Added new function
8184 silc_server_command_identify_check.
8186 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8187 to set the command to already allocated Command Payload.
8189 * Tested private message sending in router environment with two
8190 routers, two servers and two clients. Fixed minor bugs and now
8193 * Fixed segfault from client's NAMES command. Used to crash if
8196 * Forwarded packets must not be routed even if it is not destined
8197 to the receiver. Changed server code comply with this.
8199 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8201 * Added `require_reverse_mapping' boolean value to ServerParams
8202 structure. If TRUE (not default) the server will require that
8203 the connecting host has fully qualified domain name.
8205 If the reverse mapping is not required and hostname could not be
8206 found the IP address is used as hostname.
8208 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8210 * Implemented version string checking to both client and server.
8211 The check is incomplete currently due to the abnormal version
8212 strings used in development version of SILC.
8214 * Changed all command functions in server to use the new
8217 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8219 * Changed char *data to unsigned char *data in ID Cache system to
8220 support binary data as ID Cache data. Changed code to support
8221 binary data in lib/silccore/idcache.c.
8223 * Renamed silc_server_packet_relay_command_reply to
8224 silc_server_command_reply as it is normal packet receiving
8225 function. Rewrote the function to accept command replys for
8226 servers and not only for clients.
8228 * Mark remote router always as registered server if we are connecting
8229 to it. Otherwise, commands sent by the router to us are ignored.
8231 * All ID List find routines now returns the ID Cache Entry pointer
8232 as well if requested.
8234 * WHOIS command works now in router environment, tested with two
8235 routers, two servers and two clients.
8237 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8238 in router environment (as it is almost equivalent to WHOIS) but
8239 hasn't been tested thoroughly. Added new functions:
8241 silc_server_command_identify_parse
8242 silc_server_command_identify_send_reply
8243 silc_server_command_identify_from_client
8244 silc_server_command_identify_from_server
8246 * Disabled route cache adding because adding two different ID's with
8247 same IP replaces the old cache entry thus giving wrong route.
8248 The entry->router->connection is always the fastest route anyway
8249 so route cache may not be needed. Of course, new routes maybe
8250 established after receiving the ID when the entry->router->connection
8251 might not be anymore the most optimal.
8253 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8255 * Add route cache for received ID for fast routing.
8257 * Added silc_server_packet_route to route received packet on router
8258 that is not destined to us.
8260 * Renamed silc_server_get_route to silc_server_route_get.
8262 * Added id_string and id_string_len fields into SilcServer to
8263 include encoded ServerID for fast comparing without excess
8264 encoding of the ID's.
8266 * Cleaned up WHOIS command on server side. Added following static
8269 silc_server_command_whois_parse
8270 silc_server_command_whois_check
8271 silc_server_command_whois_send_reply
8272 silc_server_command_whois_from_client
8273 silc_server_command_whois_from_server
8275 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8276 arguments in command replies. All command functions should be
8277 updated to use this macro.
8279 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8281 * Minor typo fixes on command reply handling on server.
8283 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8285 * Added silc_server_command_add_to_channel internal routine to add
8286 the client to the channel after router has created the channel and
8287 sent command reply to the server.
8289 * Added generic silc_server_send_command to send any command from
8292 * Use static buffer with ID rendering instead of duplicating data.
8294 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8296 * Fixed a channel user mode bug when joining to a channel server gave
8297 everybody channel founder rights, oops.
8299 * We mark ourselves as the router of the incoming server connection
8300 if we are router ourselves. This way we can check in some packet
8301 sending functions whether it is locally connected server. For
8302 incoming router connections we put NULL.
8304 * For router sending packets locally means now always sending the
8305 packet cell wide; to local clients and local servers. For normal
8306 server sending packet locally means sending it to only local
8309 * Fixed the JOIN command to really work in router environment. If the
8310 channel is created it is always created by the router. Router is
8311 also responsible of making the initial joining to the channel,
8312 sending JOIN notify to the sending server and distributing
8313 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8314 does not exist server doesn't do anything else but forward the
8315 command to the router which performs everything.
8317 * Added silc_server_send_channel_key function to send the Channel Key
8320 * Added silc_server_create_channel_key to create new channel key. The
8321 channel key is now re-generated everytime someone joins or leaves
8322 a channel, as protocol dictates. Note: channel->key_len is the
8325 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8327 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8328 packet_receive.[ch] to separate packet sending and receiving
8329 routines. The server.[ch] now includes everything else including
8330 actual packet processing (writing and reading data) and other
8333 Renamed silc_server_private_message_send_internal to
8334 silc_server_send_private_message. The routine is still though
8335 used only to relay private messages as server does not send
8336 private messages itself.
8338 Renamed silc_server_new_channel to silc_server_create_new_channel
8339 and added new function sicl_server_new_channel that handles the
8340 incoming New Channel packet. Added also new sending function
8341 silc_server_send_new_channel to send New Channel Payload.
8343 * Added new function silc_server_notify to process incoming notify
8344 packet to the server/router. Server may then relay the notify
8345 to clients if needed.
8347 * Added new function silc_server_new_channel_user to process incoming
8348 New Channel User packet. Router will redistribute the packet and
8349 send JOIN notify to its local clients and locally connected servers
8350 if needed. Normal server will send JOIN notify to its local client
8351 on same channel when received this packet. Added also corresponding
8352 sending function silc_server_send_new_channel_user to sent the
8355 * Added boolean route argument to send_notif_to_channel and
8356 packet_send_to_channel functions to attempt to route the packet
8357 if it is TRUE and send only locally if it is FALSE.
8359 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8361 * silc_server_replace_id now broadcasts the received replace ID
8362 packet if it is not broadcast packet already. The router must
8363 broadcast to inform other routers about changed ID.
8365 * Added backpointer to server's router into SilcServer context in
8366 silcd/server_internal.h.
8368 * Fixed silc_server_packet_broadcast to send correct broadcast
8371 * The channel key is now distributed to the local client as soon
8372 as it is received from the router (in router environment) so that
8373 no other packet may be sent for the channel until client has
8376 * silc_server_remove_channel_user now broadcasts the received
8377 Remove Channel User packet if it is not broadcast packet already.
8378 The router must broadcast to inform other routers about removed
8381 * Added users field into SilcPacketContext that is a reference count
8382 of the context. One can increase the reference count by calling
8383 silc_packet_context_dup which is now changed to just increase the
8384 reference count instead of duplicating the data. The reference
8385 count is decresed by calling silc_packet_context_free that will
8386 free the data after the reference count hits zero.
8388 For now on the packet context and everything allocated into it
8389 (including the raw packet from network) must be freed by calling
8390 the new silc_packet_context_free function. Added also new function
8391 silc_packet_context_alloc that must be used now to allocate the
8392 context. This also means that if a routine is asynchronous from
8393 silc_[client/server]_packet_parse_type the packet context must
8394 be duplicated by calling silc_packet_context_dup. Otherwise it
8395 gets free'd after silc_[client/server]_packet_parse_type returns.
8396 Also, one must remember that if packet is duplicated then its
8397 reference count must be decresed by calling the free function as
8398 many times as it was duplicated.
8400 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8401 from both client and server.
8403 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8405 * Made joining to a channel working in router environment.
8407 * Cleaned up JOIN command on server side and create function
8408 silc_server_command_join_channel internal routine to make the
8411 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8413 * Changed silc_command_pending list to SilcDList. Also, added
8414 `ident' field to SilcServerCommandPending structure to identify
8415 the reply and to call correct callback.
8417 Added silc_server_command_pending_check function to replace the
8418 corresnponding macro. The silc_command_pending list is not
8421 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8422 to set identifier to previously allocated Command Payload. It
8423 is used to set identifier for command when resending Command
8426 * Added silc_command_payload_encode_payload to encode Command
8427 Payload buffer from SilcCommandPayload structure.
8429 * Added silc_argument_payload_encode_payload to encode Argument
8430 payload buffer from SilcArgumentPayload structure.
8432 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8434 * Changed WHOIS command to support router connection on server side.
8435 The whois request is always sent to router unless the server is
8436 standalone server. After server has received the reply from the
8437 router will it send the reply to the client.
8439 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8440 broadcast received broadcast packet. The function is used only
8441 by router. The broadcast packet is always sent to the router's
8444 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8445 render given ID to printable string, for log files for example.
8447 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8449 * Made basic router to router connections working. At least they
8450 can now connect to each other but nothing really works the way
8451 they are supposed - yet.
8453 * Added new initiator token to RouterConnection configuration
8454 file in silcd/serverconfig.[ch]. It is used to tell whether we
8455 are the initiator to the remote router or whether we'll expect
8456 the other end to connect.
8458 * Moved registering of listener task to silc_server_init, hence
8459 the server starts listenning as soon as it is run, even if it
8460 does not have connections to other routers. Let's see how well
8463 * Changed default connection retry timeouts for more suitable in
8466 * Removed cipher and such arguments from silc_idlist_add_client
8467 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8468 Added new function silc_idlist_add_data to add the keys and stuff
8471 * Added SilcIDListData structure and added it to SilcClientEntry
8472 and SilcServerEntry as their first field in the structure. This
8473 way we can explicitly cast the ID entries to the SilcIDListData
8474 structure and get common data for the entries. In past, we had
8475 to first check what type of connection it is and then cast it to
8476 correct ID entry type. Now, we can directly cast the opaque
8477 pointer to the SilcIDListData (no matter what ID entry it actually
8478 is) and get the data needed.
8480 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8482 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8483 in some circumstances even if threre were timeout tasks, though not
8484 IO tasks, but tasks anyway. Now fixed.
8486 * Defined SilcServerConnection structure to hold connection specific
8487 stuff about directly connected servers and routers. The definition
8488 is currently in silcd/server_internal.h. I thought about having
8489 a bit more important role fro this struct but for now it is used
8490 only when connecting to other server (or router actually).
8492 * Added connecting retry support in server when connecting to
8493 router(s). The retry feature implement exponential backoff
8494 algorithm. Also, added SilcServerParams structure to hold default
8495 parameters for server. For now, it include these retry settings
8496 and are hard coded. After server is moded to be as Silc Server
8497 Library this structure will be more important.
8499 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8501 * Changed client librarys channel->clients table to SilcList and
8502 changed code accordingly.
8504 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8506 * Changed client's channel table to SilcList and changed code
8507 accordingly. Also changed SilcChannelClientEntry to include back-
8508 pointer to the channel so that client entry can use that structure
8509 as list as well and we have fast cross-reference to the channel.
8510 This change dramatically decreased the complexity of channel
8511 handling with client entry and vice versa (removed one extra
8512 loop when searching for channel entry from many functions).
8514 * Changed server->sim from table to SilcDList and changed code
8517 * NAMES command can now be used from user interface. It will show
8518 the user list on the channel, neatly.
8520 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8521 Code now saves realname of the user if it becomes available.
8523 * Renamed configure.in to configure.in.pre and made ./prepare
8524 script to automatically add correct version string to
8525 configure.in which it creates from configure.in.pre.
8527 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8529 * NAMES command reply now shows users mode with the nickname when
8532 * Moved silc_client_ch[u]mode[_char] functions from
8533 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8534 place sucks, they are utility functions and should be in some
8537 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8539 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8542 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8546 * Added TRQ (efficient deque and list library) into lib/trq. This is
8547 a very good list library that is currently used in the SILC. Defined
8548 SilcList API over the library because I didn't like the API very
8549 much. See lib/trq/silclist.h for the API and examples of how to
8550 use the API. Fixed various places in the code to use the new
8551 SilcList API. The SilcList is meant for lists that has a structure
8552 already defined as a list. It is not suitable to add just some
8553 context to the list (in TRQ, the context is the list actually).
8555 So, I defined SilcDList that can be used for the purpose where
8556 predefined list structure does not exit. This can be used as
8557 such list. Now some context just can be added to the SilcDList.
8558 Currently this list is not used in the SILC just yet, though there
8559 are a lot places where this can replace dynamically allocated
8560 tables and I will fix these places, later, to use SilcDList.
8561 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8562 and use TRQ internally).
8564 Also fixed some annoying warning messages that the original TRQ
8565 code generated. Also minor changes to TRQ's Makefile.in.
8567 * Added support for querying by Client ID to both WHOIS and
8568 IDENTIFY commands into server, as required by the protocol.
8570 * Removed method function pointers from SilcBuffer structure. They
8571 weren't used to anything and just increased the context size for
8572 no good reason. This change also made silc_buffer_alloc and
8573 silc_buffer_free functions inline functions.
8575 * Disabled command flooding detection support until it's fixed so
8576 that it accepts commands in but does not execute them more than once
8579 * Added silc_net_localhost(), to return local hostname, into
8580 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8581 that must be initialized before calling silc_client_init.
8583 * Added new function: silc_server_send_notify_on_channels to send
8584 notify messages to all channels client has joined. It is assured
8585 that the message is sent only once per client.
8587 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8588 lib/silcutil/silcutil.[ch] as silc_format function. The new
8589 function is generic and is used by server as well, not only by
8590 the logging routines.
8592 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8593 the provided version string was not acceptable. Added new function:
8594 silc_ske_check_version into lib/silcske/silcske.h. The function
8595 must be implemented by the application (client or server) and it
8596 does not reside in the SKE library. The function checks the version
8597 string remote end sent.
8599 * Added back pointers (to opaque context and to SilcSocketConnection)
8600 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8602 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8603 duplicate packet context structure.
8605 * Changed `notify' client operation to send same arguments as client
8606 receives from server except for ID's. ID's are mapped to correct
8607 ID entry and that is returned. Also, if channel entry is not sent
8608 by server but the notify is for channel the channel entry is sent
8609 to application (otherwise application doesn't know that it is for
8610 channel (library gets it from packet's Destination ID)).
8612 * Added silc_client_remove_from_channels into client library to
8613 remove a client from all channels it has joined to. Used when
8614 received SIGNOFF notify from server. Added also new function
8615 silc_client_replace_from_channels to replace old ID entry with
8616 new ID entry on all channels. Used when received NICK_CHANGE
8619 * Fixed ID Cache list handling in silc_idlist_get_client in
8620 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8621 to get (or query) client by ID.
8623 * Updated TODO list.
8625 * Added connection authentication status message defined by the
8626 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8627 support for these into the code in client and server side.
8629 * Added generic function silc_client_send_command to send any command
8630 with variable argument list. Application should use this function
8631 to send commands if the command functions provided by the library
8632 does not suite for the application's user interface needs.
8634 * Added new `failure' client operation. Application is notified about
8635 received failure packet if client is executing a protocol. In this
8636 case the protocol's execution has failed.
8638 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8639 is required by the protocol.
8641 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8642 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8645 * Added status flag to SilcSKE object to indicate realtime status
8646 of the SKE protocol.
8648 * Application receives now exactly same command reply arguments as
8649 the library receives from server. However, if ID is received the
8650 corresponding ID entry is returned to the application (eg. Client
8651 ID is mapped to correct SilcClientEntry entry and that is returned).
8652 Changed command_reply client operation due to this change.
8654 * Changed all ID's in commands and in command replys as ID Payloads.
8655 Change affected both client and server side codes.
8657 All ID's sent in SILC network (with execption of ID's in SILC
8658 Packet header) are sent in ID Payload to support variable length
8661 * Server now notifies nick changes and notifies all clients on
8662 the channels about the new nickname (about the new Client ID,
8665 * Implemented CMODE command to change channel modes. Supports all
8666 channel modes defined by the protocol specs except ban and invite
8667 lists. (Also, private channel key mode is supported but support for
8668 setting private channel key in client is missing, thus, this mode
8669 has no effect on client side (except that server requires that the
8670 client uses private channel key and normal channel traffic does not
8673 Also, invite mode works per se, but INVITE command does not work
8674 yet correctly, so you can set channel as invite only channel but
8675 inviting clients to the channel does not work (it is yet to be
8676 thought what's the best way to do it).
8678 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8679 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8680 Implemented CUMODE command to change user's mode on the channel.
8681 Supports all modes defined by the protocol specs.
8683 * Added NAMES command reply to return users modes on the channel.
8685 * Removed unnecessary and slow ciphers from lib/silccrypt.
8687 * Set SO_KEEPALIVE option to connection sockets by default.
8689 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8691 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8692 redefined the Notify Payload into protocol specs.
8694 * Added silc_id_payload_parse_id to get ID directly from raw
8697 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8699 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8700 accept searching by Client ID as well.
8702 * Added support for LEAVE and SIGNOFF notify types in client library.
8704 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8705 to parse ID Payload from raw data.
8707 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8709 * Added flags parameter into silc_ske_assemble_security_properties
8710 function in lib/silcske/silcske.[ch].
8712 * Changed notify client operation to fit better for notify messages
8713 sent by server. The notify payload received from server is now
8714 passed to the application (after parsing it to SilcNotifyPayload).
8715 It is application's responsibility to retrieve the arguments
8716 from the payload and show the message the way it wants. The message
8717 sent by server is implementation specific.
8719 * Changed public keys to comply with the protocol specification.
8720 Old public keys are not supported anymore and are not compatible.
8722 * Removed nickname from Channel Payload as the latest draft removed
8723 it. The client must resolve the nickname from the NAMES command
8724 reply received when it joined the channel.
8726 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8728 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8730 * Fixed some errors in protocol specification drafts.
8732 * Created lib/silccore/silcnotify.c to implement Notify Payload
8733 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8734 generic payloads described by protocol specifications. The file
8735 includes implementations for ID Payload and Argument Payload.
8737 * Changed Command Payload implementation to use the new Argument
8738 Payload. Changed command_xxxx_payload to command_payload_xxxx
8739 to comply with SILC coding conventions.
8741 * Added suppport for Argument Payload handling in Notify Payload
8742 implementation as protocol requires it. Added the new support
8743 into server and client lib as well.
8745 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8747 * Added support for multiple nicknames on same channel. [n] is
8748 added locally to the nickname if there are more than one same
8749 nicknames on the channel.
8751 * Server now sends all nicknames that matched WHOIS request.
8752 Client also shows the list received from server.
8754 * Added TOPIC command to client side. User can now set and show
8755 current topic on channel.
8757 * Added MOTD command to client and server. Also, server sends the
8758 motd when client connects to the server.
8760 * Changed version strings to comply ISO 8601.
8762 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8764 * Fixed protocol error handling in client library. It should now
8765 cope even if the SKE fails for some reason.
8767 * Made new protocol specification drafts for submitting to IETF.
8769 * Implemented TOPIC command to server in silcd/command.c.
8771 * Added two new notify types into lib/silccore/silcnotify.h:
8772 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8773 notify nickname change and topic setting/change on a channel.
8775 * API change of command_reply operation in client library. The
8776 application gets now the status type received from server as well.
8778 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8780 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8782 * Cras fixed and optimized the packet handling even further and
8783 it should work now. Minor change to the prototype of function
8784 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8786 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8788 * Added new function into lib/silcutil/silcschedule.[ch]:
8789 silc_schedule_with_fd to select() a specified fd. The function
8790 returns after timeout expires or data arrives or goes. The
8791 function is used by packet routines to wait that all data is
8792 received from network.
8794 * Fixed data reading from network in lib/silccore/silcpacket.c.
8795 The code now assures that all data is read from the fd and then
8796 continues packet processing. This was a bug fix since the code
8797 used to drop some data in some circumstances.
8799 * Added new function into lib/silcclient/client.[ch]:
8800 silc_client_start_key_exchange to start key exchange after
8801 connection has been established to server. The code internally
8802 now uses this funtion but its main purpose was to provide it
8803 for applications that perform their own connecting. After
8804 application has created a connection it merely calls this
8805 function to start the key exchange between client and server.
8806 The library takes care of everything else after that.
8808 Updated also lib/silcclient/README to explain the usage of
8811 * Do not send to application information that connection has
8812 been established. Application gets notified it by connect
8815 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8817 * Applied cras's patch to add silc_schedule_one function. The
8818 function runs scheduler once and returns.
8820 * Fixed the scheduler after cras messed it up. The timeout
8821 handling works now as it's supposed to work.
8823 * Added into lib/silccore/ silcnotify.h to include notify
8824 message types support. Changed silc_server_send_notify*
8825 functions, in server.[ch], to support those new notify types.
8826 Added the support for the notify types into client library,
8827 as well. Added new notify client operation into ops.h in
8830 * Changed silc_server_packet_send_to_channel to send normal
8831 packets instead of just channel message packets. The function
8832 is now used to send the notify packets to channels. It is not
8833 used to send channel message packets anymore, as server never
8836 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8837 va_arg()s as it seems to require it nowadays. I guess, if SILC
8838 is compiled with older va_arg() the new code should work anyway.
8840 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8842 * Splitted core library. Core library (lib/silccore) includes
8843 now only SILC protocol specific core (and common) components.
8844 Created new utility library (lib/silcutil) that includes more
8845 generic purpose stuff. The stuff for util library was taken
8846 from the old core library. This was minor and easy split.
8848 * Created SILC Client Library (lib/silcclient) that includes
8849 implementation of the SILC client without user interface. This
8850 was major move from silc/ directory. The code has been changed
8851 so that it is transparent towards the user interface. The
8852 silc/ directory includes now the same user interface as before
8853 and it uses the new client library. Read lib/silcclient/README.
8854 Basicly, the client library performs everything else related
8855 to SILC except user interface handling. Also, configuration
8856 files are considered to be part of user interface and library
8857 does not handle them.
8859 This change also changed a lot of structures, function naming etc.
8860 Most important change was that SilcClientWindow object was
8861 renamed to SilcClientConnection in the client library. Created
8862 also new file lib/silcclient/ops.h. Also added new files
8863 silc/local_command.[ch] and silc/client_ops.[ch].
8865 All these changes were made to make it easier for user interface
8866 designers to create what ever user interface for the SILC client
8869 It is also expected that the server will be moved to lib
8870 directory as well and SILC Server Library will be created;
8871 sometimes in the future.
8873 * Removed Local commands from lib/silccore/silccommand.h as
8874 they are application specific and new client library does not
8875 handle any of those anymore.
8877 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8878 old client implementation in silc/.
8880 * Added support for callback functions in SILC_LOG_* macros.
8881 Application can now set its own callbacks that will be called
8882 instead of using the default functions that will always print
8883 the debug messages to stderr (or stdout). Also, debugging can
8884 now be disabled by setting silc_debug to FALSE and re-enabled by
8885 setting it to TRUE. Note, that logging will still work even
8886 if debugging is disabled.
8888 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8889 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8890 silc_log_reset_debug_callbacks.
8892 * To enable debugging in silc client one must give now -d
8893 option on command line.
8895 * Changed silc_schedule_init to automatically allocate task queues
8896 if they are not allocated before calling it.
8898 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8900 * Added GMP 3.1 into math library.
8902 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8904 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8905 a channel in SILC network. The packet is used by servers and
8906 routers to notify other routers that user has left a channel.
8907 This little feature was missing until now. Added the feature
8908 to protocol specification as well.
8910 Added functions: silc_server_send_remove_channel_user and
8911 silc_server_remove_channel_user into server.[ch].
8913 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8914 lib/silccore/silcpacket.h. However, they are not implemented
8917 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8919 * Fixed joining to a channel and sending channel messages
8920 between server and router. The channel message sending should
8921 now work inside a cell.
8923 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8925 * Fixed the private message sending between server and router.
8926 The private message sending should now work inside a cell.
8928 * Added silc_server_replace_id into server.[ch] to replace
8929 existing ID in the SILC network.
8931 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8932 and silc_idlist_replace_server_id into idlist.[ch] in server.
8934 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8936 * Fixed the server to server connections. Server can again now
8937 connect to router. Router to router connections probably does
8940 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8942 * Added dynamic protocol registering support. Now protocols can
8943 registered and unregistered on the fly. Patch by cras.
8945 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8947 * Added lib/contrib directory to hold routines that some platforms
8948 don't have but are needed by SILC.
8950 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8951 into lin/contrib to provide getopt() and getopt_long() for
8952 those who don't have it.
8954 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8956 * Added AWAY command to client. When away message is set and
8957 client receives a private message packet the client automatically
8958 replies to the sender with the away message.
8960 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8961 bug seemed to be the cause of recent problems when compiling
8964 * Added version detection support to SKE protocol specification
8965 and added the new changes to the SKE implementation as well.
8966 There were other minor changes in the SKE protocol as well.
8968 Many changes in lib/silcske/silcske.[ch] and in
8969 lib/silcske/payload.[ch].
8971 * Added ^U functionality, clear input line. Patch from cras.
8973 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8975 * Mainly small bugfixes on core library. Fixed some debugging
8976 logging and buffer overflow in silclog.c.
8978 * Updated config.sub and config.guess on the distribution tree.
8980 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8982 * Added command lagging support in server. Client may execute
8983 commands now only once in two seconds.
8985 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8987 * Optimized packet reception. MAC computation and checking is now
8988 also more optimized. A lot previously duplicated code is now
8989 used as generic by both client and server.
8991 * Fixed key pair generation in clientutil.c
8993 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8995 * Added into lib/silccore/silcbufutil.[ch] new function;
8996 silc_buffer_realloc.
8998 * Moved generic packet sending/encryption functions to
8999 lib/silccore/silcpacket.[ch] from client and server. Some
9000 rewriting of the functions.
9002 * Moved all generic packet reception/decryption functions to
9003 lib/silccore/silcpacket.[ch] from client and server. The
9004 packet processing is now much cleaner in both client and server.
9005 These were major changes in both client and server.
9007 * Created many common functions in server to do packet sending.
9008 Previously code were duplicated a lot, this has been removed
9011 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9013 * Rewrote major parts of the ID cache system. Don't know
9014 whether it is better now or not but at least the API is more
9017 * Major rewrite on ID cache stuff on client because of the ID
9018 cache API changes. Added idlist.c to client.
9020 * Also major rewrite on ID cache stuff on server as well.
9021 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9022 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9023 in hand, instead they are all put into the ID cache system now.
9024 All server_idlist_* routines uses ID cache now instead of
9025 traversing its own lists (those lists does not exist anymore).
9026 SilcIDList though still exists. Also, SilcXXXEntry's are
9029 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9031 * Finally made the SKE implementation compliant to the protocol
9032 specification. All mp integers are now binary encoded as
9033 opposed being HEX encoded.
9035 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9038 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9039 functions: silc_[encode/decode]_pem. Also added function
9040 silc_encode_pem_file to PEM encode with newlines ('\n') for
9043 * SILC public keys are now encoded either PEM or binary. Same
9044 option is for private keys as well. By default private keys
9045 are binary encoded and public keys PEM encoded. Silly HEX
9046 encoding were removed.
9048 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9049 function to create fingerprints.
9051 * Fixed a bug in SHA1; does not change the original data anymore.
9053 * Partly implemented INFO command on client and server side.
9054 Fixed CLEAR command. Changes to SERVER command; show current
9055 server(s) when giving command without arguments. Added
9056 VERSION command to client.
9058 * Added check to server that unregistered connections cannot
9059 execute commands (unless it is specificly allowed).
9061 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9063 * Fixed screen refresh.
9065 * Fixed channel joining bug from client. On some circumstances
9066 client tried to join to a channel it had already joined.
9068 * Added public key verification process into client's protocol.c.
9069 The client now verifies the public key from user and saves
9070 it into ~./silc/serverkeys/ directory.
9072 Added into: clientutil.[ch]: silc_client_verify_server_key.
9074 * Changed SKE protocol's silc_ske_initiator_finish function
9075 to accept callback function that verifies the received public
9076 key. Removed old silc_ske_verify_public_key function.
9078 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9080 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9081 silc_pkcs_private_key[_data]_set.
9083 * Made the password and public authentication more cleaner in
9084 server's protocol.c.
9086 * Removed historic and obsolete protocol `channel_auth' from
9087 both client and server.
9089 * Removed wrong way of sending command status messages from
9090 server to client in server's command.c. The old way violated
9091 protocol specification.
9093 Changes to silccore/silccommand.[ch]: removed
9094 silc_command_encode_status_payload -> not needed anymore,
9095 changed silc_command_encode_payload_va to accept extra
9096 argument on variable argument list. The argument type must
9097 now be provided to the function. Also, added new function:
9098 silc_command_encode_reply_payload_va which is same as
9099 normal command_encode_payload_va except command status type
9100 is provided as extra argument.
9102 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9104 * Added ~./silc directory handling. The directory includes the
9105 public and private keys for the client.
9107 Added silc_client_check_silc_dir, silc_client_create_identifier
9108 and silc_client_load_keys.
9110 * Implemented SILC protocol compliant public key. Added public
9111 and private key saving to and loading from files.
9113 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9114 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9115 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9116 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9117 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9119 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9120 silc_pkcs_load_[public/private]_key.
9122 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9124 * Added silc_server_get_route (route.[ch]) to get connection
9125 data for the fastest route for given ID.
9127 * Implemented INVITE command on client and server. The command
9128 were re-defined in the SILC Protocol Specification and the
9129 implementation now complies with the specification.
9131 * Implemented PING command on client and server.
9133 * Implemented NAMES command on client and server. The server side
9134 supports currently only normal server not router server yet.
9135 Some changes to NAMES definition in SILC protocol specification.
9137 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9139 * Implemented LEAVE command on client and server.
9141 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9142 again. This change was made to the protocol as well. Server
9143 should not violate the protocol specification anymore.
9145 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9147 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9148 was tested. SOCKS4 was not but should work anyway.
