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

1090 * Redefined the Status Payload to include now two 8 bit fields,
1091 instead of one 16 bit field. This now makes it possible to
1092 send list of errors. Updated the protocol specs and the code
1093 in core library, client library and server. Protocol TODO #1.
1094 Affected files are lib/silccore/silccommand.[ch],
1095 lib/silcclient/command_reply.[ch], silcd/command.c,
1096 silcd/command_reply.c and silcd/packet_receive.[ch].
1098 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1100 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
1101 must be handled by the application and should tell the application
1102 that an error message was already printed, and it should print the
1103 config coords (line, filename, ...). Affected files are
1104 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
1106 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
1107 server config parsing code more readable.
1109 Fixed a bug in the fetch_logging() config callback.
1111 Affected files is silcd/serverconfig.c.
1113 * Drop root privileges when started in foreground. Don't drop them
1114 if debugging also. Affected file is silcd/silcd.c.
1116 Mon Apr 8 17:00:41 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1118 * Added more IM-like features by introducing new user modes
1119 for setting various presence information. Added new modes:
1120 INDISPOSED, BUSY, PAGE, HYPER and ROBOT. Updated protocol
1121 specs and code. Protocol TODO #19. Affected files are
1122 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
1123 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
1125 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1127 * Added STATS command to the protocol after all, to return
1128 various statistical information about the network. It can
1129 be used by clients to retrieve statistical information, and
1130 servers may use it to to fetch cell and network wide
1131 statistics from router. Updated the protocol specs and
1132 implemented it to the server. Protocol TODO #16.
1133 Affected files are lib/silccore/silccommand, silcd/command.[ch],
1134 silcd/command_reply.[ch].
1136 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1138 * The LIST command reply in client libary now adds new channel
1139 entry if the returned channel doesn't exist yet in cache,
1140 and returns the channel entry to the application in the
1141 command_reply client operation. Affected file is
1142 lib/silcclient/command_reply.c.
1144 * Changed the channel message payload's MAC generation to
1145 include the IV in the MAC as well. This way all relevant
1146 parts of the channel message payload are authenticated also
1147 with the channel message MAC (and not only by packet MAC).
1148 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
1149 Affected file is lib/silccore/silcchannel.c.
1151 * Fixed the SKE to save the remote version, since the
1152 silc_ske_parse_version mistakenly checked wrong version,
1153 after it replaced the start payload. Affected files are
1154 lib/silcske/silcske.[ch].
1156 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1158 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
1159 string utility functions. Added there also new functions
1160 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
1161 Affected files lib/silcutil/silcstrutil.[ch].
1163 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
1164 files are lib/silcutil/silcstrutil.[ch].
1166 * Defined that the security property fields in SKE SHOULD be
1167 UTF-8 encoded, defined that version string MUST be US-ASCII
1168 encoded, defined that passphrases sent in connection
1169 authentication protocol MUST be UTF-8 encoded. Implemented
1170 these to the client and server. Defined also that other
1171 passphrases sent in the protocol MUST be UTF-8 encoded.
1172 Affected files are lib/silcske/silcske.c,
1173 lib/silcclient/protocol.c, silcd/protocol.c,
1174 silcd/serverconfig.c, and lib/silccore/silcauth.c.
1176 * Changed the silc_client_close_connection interface to not
1177 need the SilcSocketConnection which should not be visible
1178 to application. Affected files are lib/silcclient/client.c
1179 and lib/silcclient/silcclient.h.
1181 * Rewrote the text for Private Message Key Payload in the
1182 protocol specification. Protocol TODO #11.
1184 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
1186 * Upgraded the protocol version to 1.1, updated protocol specs
1189 * Added the nickname as new argument to NICK_CHANGE notify and
1190 added it to protocol specs and implemented it to client and
1191 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
1192 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
1193 lib/silcclient/client_notify.c.
1195 * Added the killer's client ID to the KILLED notify and added
1196 it to protocol specs and implemented it to client and server.
1197 Protocol TODO #13. Affected files are silcd/command.c,
1198 silcd/packet_receive.c, packet_send.[ch],
1199 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1200 The killer's client entry is now returned to application in
1201 the `notify' client operation.
1203 * Fixed the Max Argument fields that had too large value set
1204 in the protocol specs. Protocol TODO #14.
1206 * Added the LEAVE command reply to return the ID of parted
1207 channel. Updated protocol specs and implemented it to the
1208 client and server. Protocol TODO #15. Affected files are
1209 silcd/command.c, lib/silcclient/command_reply.c. The channel
1210 entry is now returned to application in the `command_reply'
1213 * Rewrote the version SKE version checking in client libary
1214 and in server to use the silc_parse_version_string. Affected
1215 files are lib/silcclient/protocol.c, silcd/protocol.c.
1217 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
1218 commands that was missing it, and updated protocol specs and
1219 the server implementation. Protocol TODO #10. The affected
1220 file is silcd/command.c.
1222 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
1223 generic reply to a generic request (REQUEST flag), and
1224 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
1225 way. A draft-riikonen-silc-flags-payloads-00.txt is written
1226 to define the payload for DATA flag. Added the flags to
1227 the implementation. Protocol TODO #9. Affected file is
1228 lib/silccore/silcchannel.h.
1230 Changed the client library to return the message length
1231 to application as well in the channel_message and private_message
1232 client operations. Affected files are
1233 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
1234 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
1235 and lib/silcclient/client_ops_example.c.
1237 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
1238 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
1239 the channel. Updated protocol specs and impelemented this
1240 to client and server. Protocol TODO #6. Affected files are
1241 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
1242 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
1244 Added new options m and M to CMODE command in Irssi SILC
1245 client to set these modes.
1247 * Deprecated all administrative commands from SILC protocol
1248 since they are highly implementation specific commands.
1249 Updated protocol specs. Moved the old commands in
1250 implementations to private range of command types. Affected
1251 files are silcd/command.c, lib/silcclient/command.c and
1252 lib/silcclient/command_reply.c. Protocol TODO #8.
1254 * Fixed a bug in server where sending unknown command crashes
1255 the server. Affected file silcd/command.c.
1257 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1259 * Added SILC_PROTOCOLVERSION macro to check protocol version
1260 of a socket connection. The affected file is
1261 lib/silcutil/silcsockconn.h.
1263 * Added better error logging in rekey protocol. Affected file
1266 * Do not check public key types in SKE during rekey. Affected
1267 file lib/silcske/payload.c.
1269 * Fixed the rekey protocol with PFS, which was totally broken.
1270 Affected file silcd/protocol.c.
1272 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
1274 * Some client implementations quit network by doing first LEAVE
1275 and then immediately SIGNOFF (like Bombyx). We now do check
1276 after a short time after LEAVE notify and check whether the
1277 client is still valid after LEAVE, and if not we remove it from
1278 cache. Affected file is lib/silcclient/client_notify.c.
1280 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1282 * Merged version 1.1.4 of zlib. Even if it not currently in use,
1283 it's good not to have security holes here.
1285 * Fixed a negative refcount situtuation for the config context.
1286 Affected file is silcd/serverconfig.c.
1288 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
1290 * ROBOdoc documented lib/silcutil/silcutil.h.
1292 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1294 * Optimized even more the SilcPacketContext structure. Now
1295 totally saved 16 bytes of memory per context after optimization.
1296 Affected files are lib/silccore/silcpacket.[ch].
1298 * Made strict checks for valid SILC IDs. Affected file is
1299 lib/silccore/silcid.c.
1301 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1303 * Changed the object argument for silc_cipher_register,
1304 silc_hash_register, silc_hmac_register and silc_pkcs_register
1305 to const. Affected files are lib/silccrypt/silccipher.[ch],
1306 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
1308 * Changed the silc_get_username and silc_get_real_name to
1309 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
1311 * Fixed the Irssi SILC Client to use the silc_get_username and
1312 silc_get_real_name insted of glib routines since the glib
1313 routines only corrupt stack. Fixes the Irssi SILC to work in
1314 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
1316 * Fixed the Irssi to not use g_get_home_dir since it crashes
1317 or returns garbage on cygwin and corrupts stack. Added function
1318 get_home_dir to Irssi routines. Affected files are
1319 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
1321 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1323 * Made some structure optimizations. SFTP memory FS MemFSEntry
1324 entry structure. Optimized SilcTask structure. Optimized
1325 SilcPacketContext structure.
1327 Affected files lib/silcsftp/sftp_fs_memory.c,
1328 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
1330 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1332 * And yet again reverted back the config thing since Johnny
1333 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
1336 * Fixed memory leaks from config object. Affected files are
1337 silcd/serverconfig.[ch].
1339 * Added support for adding new connections to the server in rehash.
1340 After rehash they take effect.
1342 Added support for changing the maximum allowed connections in
1343 rehash. The number can grow but going smaller is not supported.
1345 Added function silc_server_num_sockets_by_remote to the
1346 silcd/server_util.[ch].
1348 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
1350 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1352 * Added preliminary checking during config parsing for a valid
1353 public/private key and removed further checks in the code.
1354 Affected files are silcd/serverconfig.[ch], server.c.
1356 * Moved functions silc_server_drop() and silc_server_daemonise()
1357 from server.c to silcd.c since they are stricly related to
1358 the application activity.
1360 * Reverted a small part of the automatic ref/unref since
1361 it caused a double unref in some situations. Affected
1362 files are silcd/silcd.[ch], server.c, serverconfig.c.
1364 * Added some .cvsignore files in the lib directory.
1366 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1368 * Fixed silc_net_gethostbyaddr to correctly resolve by
1369 address. Affected file lib/silcutil/silcnet.c.
1371 * Fixed the notify relaying to client. The HMAC to be used
1372 with relayed packets ws wrong and caused decryption failure
1373 at the client end. Affected file is silcd/packet_receive.c.
1375 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1377 * Created new branch silc_protocol_1_0_branch.
1379 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
1381 * Changed the silc_server_config_* routines to be SilcServer
1382 independent. They are now officially application specific code
1383 and not part of generic server implementation. Affected files
1384 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
1386 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1388 * Added automatic referencing of config context in the
1389 silc_server_config_alloc, and automatic unreferencing in the
1390 silc_server_config_destroy. Affected files are
1391 silcd/serverconfig.[ch], silcd/silcd.c.
1393 * Fixed the silc_log_quick handling in the logging routines.
1394 It didn't log quickly when it was TRUE. Affected file is
1395 lib/silcutil/silclog.c. Also the flush delay was set even
1396 if it was 0 in config file. Affected file is
1397 silcd/serverconfig.c.
1399 * Added support for changing key pair of the server in rehash.
1400 Affected file silcd/server.c.
1402 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1404 * Fixed the TOPIC_SET notify to not cras. It changed the topic
1405 too early, before getting the channel entry. Affected file
1406 is silcd/packet_receive.c.
1408 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1410 * Added functions silc_server_config_[ref/unref], these are used
1411 to prevent that the config object is destroyed.
1413 No longer directly affect global variables silc_log_quick and
1414 silc_log_delay, they are first cached inside the config object
1415 and then applied with silc_server_config_setlogfiles().
1417 silc_server_config_set_defaults() is now internal to
1418 serverconfig.c, there are no reasons to show this internal stuff
1421 Affected files are silcd/serverconfig.[ch].
1423 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
1424 fprintf's to stderr, since some code may be executed again after
1425 the server went into the background. Affected files are
1428 * Added rehash support. Added function silc_server_rehash() that
1429 will perform all the basic tasks of the rehashing procedure.
1431 * Added command line option `-x, --hexdump'. This will enable the
1432 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
1433 The option `--hexdump' implies `--debug'.
1435 * Fixed a bad bug in the logging APIs (silcutil library) where
1436 the application would crash after calling silc_log_reset_all().
1438 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1440 * Fixed the KICKED notify handling in client library to
1441 correctly remove the channel and all entries from the
1442 channel when I was kicked. This bug crashed the client.
1444 Fixed yet another but in KICKED notify handling to remove
1445 the kicked client correctly from the channel.
1447 Affected file is lib/silcclient/client_notify.c.
1449 * Fixed a minor bug in looking up correct client entry
1450 in KICKED notify in server. Affected file is
1451 silcd/packet_receive.c.
1453 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
1454 sources correctly to distribution. Fixes --with-gmp option.
1456 * Removed the manual rehashing from ID Cache, and changed it
1457 to use the SILC Hash Table's auto rehash feature. Affected
1458 file is lib/silccore/silcidcache.c.
1460 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1462 * Fixed a bug in the silc_client_nickname_format function that
1463 handles the multiple same nickname formatting. Two clients
1464 with same nickname caused problems after the first one left
1465 and rejoined. It didn't format the nickname correctly.
1466 Affected file is lib/silcclient/idlist.c.
1468 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1470 * Don't change the topic if olod topic is same as new one.
1471 Affected file is silcd/packet_receive.c.
1473 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1475 * Added cross-reference support to the SILC Documentation
1476 generator. All types across all HTML files are now cross-
1477 referenced. Affected files util/robodoc/generator.c and
1478 scripts/silcdoc/silcdoc.
1480 * Added file lib/silcutil/silctypes.h to include all the
1481 arithmetic type definitions and some macros. Removed
1482 includes/bitmove.h and moved macros to silctypes.h.
1484 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1486 * Merged bugfixes for Irssi SILC client from irssi.org CVS.

1490 * Added `type' argument to silc_id_payload_parse_id function which
1491 now returns the type of the ID to the sent pointer. Affected
1492 file is lib/silccore/silcid.[ch].
1494 * Added check for CMODE_CHANGE notify type that mode change is
1495 allowed by the sender. Affected file silcd/packet_receive.c.
1497 * Added check for CUMODE_CHANGE notify type that mode change is
1498 allowed by the sender. Affected file silcd/packet_receive.c.
1499 Added the ID type as CUMODE_CHANGE notify type as argument
1500 to the `notify' client operation. Affected files are
1501 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
1503 * Added function silc_client_add_server to the client library.
1504 Added support for resolving also channel and server info when
1505 received unknown entity in notify packet. Affected files are
1506 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
1508 * Added function silc_command_get_status to return the command
1509 status from the command reply's argument payload. Affected files
1510 are lib/silccore/silccommand.[ch].
1512 * Added check for KICKED notify type that the kicking is
1513 allowed by the client. Affected file silcd/packet_receive.c.
1515 * Created function silc_get_input which can be used to get input
1516 (echo on or off) from user on command line. Affected files are
1517 lib/silcutil/silcutil.[ch].
1519 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1521 * Optimized silc_server_packet_relay_to_channel function.
1522 Added new function silc_channel_message_payload_encrypt which
1523 can be called directly if channel message payload needs to
1524 be encrypted and is already encoded (no need to call _encode
1525 function). Packet relaying is now done by router without any
1526 extra memory allocations. Affected files are
1527 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
1528 silcd/packet_send.c.
1530 * Fixed the INVITE notify handling. It took wrong arguments
1531 as invite list and invite delete. Affected file is
1532 silcd/packet_receive.c.
1534 * Added check for TOPIC_SET notify type that the topic change is
1535 allowed by the client. Affected file silcd/packet_receive.c.

1538 the client. Affected file silcd/packet_receive.c.
1540 * Changed the silc_server_client_on_channel to return the
1541 SilcChannelClientEntry as well. Moved the function
1542 silc_server_check_cmode_rights to server_util.[ch].
1543 Affected files are silcd/server_util.[ch], silcd/command.c.
1545 * Added function silc_server_check_umode_rights to check whether
1546 changing client's user mode is allowed. Added check for
1547 UMODE_CHANGE notify type that the umode change is allowed
1548 by the client. Affected files are silcd/server_util.[ch],
1549 silcd/packet_receive.c and silcd/command.c.
1551 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1553 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
1554 ID length. It ignored that ID can be IPv6 based as well.
1555 Affected file lib/silccore/silcpacket.h.
1557 * Fixed the silc_id_id2str and silc_id_str2id to take the
1558 IPv6 address offset's into consideration. Affecte file is
1559 lib/silccore/silcid.c.
1561 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1563 * Fixed the internal Unix scheduler functions to check for
1564 NULL context they may receive. The affected file is
1565 lib/silcutil/unix/silcunixschedule.c.
1567 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
1569 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
1570 can specify different directory with --home command line
1571 parameter. Affected files irssi/src/silc/core/client_ops.c,
1574 * SILC-specific commands aren't now executed if the active server
1575 isn't of SILC-type, so there won't be problems with having
1576 IRC and SILC protocol support in same client. Affected files
1577 irssi/src/silc/core/silc-channels.c, silc-servers.c,
1580 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1582 * Improved the signal support in SILC Schedule. Added new
1583 function silc_schedule_signal_call which is used by application
1584 to mark a signal to be called. It is now safe to perform
1585 any kind of tasks in signal callbacks since it is guaranteed
1586 that the application specified signal callback is called
1587 after the signal is over. Affected files are
1588 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
1590 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1592 * Added `name' field to SilcChannelPrivateKey to represent
1593 application given name for the key. Moved also the context from
1594 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
1595 Added the `name' argument also to the function
1596 silc_client_add_channel_private_key.
1598 Added function silc_client_current_channel_private_key to set the
1599 current channel private key in use.
1601 Added "change" command to KEY command which can be used to change
1602 the current channel private key. Bound the command also to
1603 alt+K (Alt+Shift+k).
1605 Also affected files lib/silcclient/client_channel.c,
1606 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
1608 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1610 * Added silc_rng_get_byte_fast function in to the
1611 lib/silccrypt/silcrng.[ch].
1613 * Changed the interface of silc_packet_assemble and the
1614 silc_packet_send_prepare. If silc_packet_assmble is now
1615 called the application does not call silc_packet_send_prepare
1616 because the library will call it automatically. These
1617 interfaces now also return a reference to the outgoing buffer
1618 which includes the assembled packet, which the application can
1619 use to encrypt the packet.
1621 Affected files are lib/silccore/silcpacket.[ch],
1622 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
1623 silcd/packet_send.c, server_backup.c and packet_receive.c.
1625 * Fixed a packet sending bug on very high load, where outgoing
1626 packet queue wasn't handled correctly and packets got corrupted.
1627 Affected files are lib/silcutil/*/silc*sockconn.c,
1628 lib/silcclient/client.c and silcd/server.c.
1630 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1632 * Added macro SILC_PACKET_DATALEN which can be used during
1633 packet assembling to check whether the data to be added to
1634 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
1635 len is truncated until it fits it.
1637 Added checks for maximum length of channel message payload and
1638 private message payload also.
1640 Added checks for maximum packet length in server and in
1643 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
1644 lib/silcclient/client.c, lib/silccore/silcchannel.c and
1645 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
1646 lib/silcclient/client_prvmsg.c.
1648 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1650 * Added silc_server_packet_queue_purge call to the
1651 silc_server_disconnect_remote to assure that all data in the
1652 queue before disconnecting is sent to the network. Affected
1653 file silcd/server.c.
1655 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1657 * Added the deleting of server's own ID cache entry to the
1658 silc_server_free function. Free also everything else that
1659 has been allocated in silc_server_init. The affected file
1662 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1664 * Added functions silc_parse_version_string, silc_version_to_num,
1665 and silc_ske_parse_version to parse SILC protocol style version
1666 strings. Affected files lib/silcutil/silcutil.[ch] and
1667 lib/silcske/silcske.[ch].
1669 * Added new configuration params: version_protocol, version_software
1670 and version_software_vendor to specify what version the remote
1671 host must at least be to be able to connect to server. The vendor
1672 string can be regex matched too. Added new function
1673 silc_server_connection_allowed to check maximum number of allowed
1674 connections, and allowed versions for incoming connections.
1675 Affected files are silcd/server.c, server_util.[ch] and
1678 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1680 * Added preliminary support for signals in scheduler. The
1681 signals we care about are now blocked always when the scheduler
1682 is locked. This way we can synchronise the use of signal with
1683 scheduler. It is guaranteed that when signal occurs the scheduler
1684 is not locked, and thus new tasks can be safely added to the
1687 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
1688 to silc_schedule_internal_init and silc_schedule_internal_uninit.
1689 Added new platform specific routines
1690 silc_schedule_internal_signals_[un]block and
1691 silc_schedule_internal_signal_[un]register.
1693 Added new functions to SILC Schedule API:
1694 silc_schedule_signal_[un]register. Each signal that application
1695 is going to use should be registered to the scheduler.
1697 Affected files are lib/silcutil/silcschedule.[ch],
1698 lib/silcutil/*/silc*schedule.c.
1700 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1702 * Check for unauthenticated client and server in the
1703 silc_server_new_client and silc_server_new_server functions.
1704 Affected file silcd/packet_receive.c.
1706 * Added function silc_string_is_ascii to check whether given
1707 string is 7-bit ASCII string. Affected files are
1708 lib/silcutil/silcutil.[ch].
1710 * Added function silc_id_is_valid_server_id into the
1711 silcd/serverid.c and added checking for valid Server ID's in
1712 silc_server_new_server. The Server ID must always be based
1713 on the server's public IP address.
1715 * Added logging of DISCONNECT packet message in the server.
1716 Affected file silcd/server.c.
1718 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1720 * Changed all library interfaces that use Global RNG to also
1721 accept SilcRng as argument. Affected files are
1722 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
1723 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
1724 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
1725 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
1726 lib/silccrypt/rsa.c.
1728 * Added function silc_pkcs_generate_key to the
1729 lib/silccrypt/silcpkcs.[ch] for applications so that they
1730 don't need to do pkcs->pkcs->init calls anymore.
1732 * Remove SilcSocketConnection from the SFTP API since it really
1733 wasn't needed there. The application has the information
1734 saved in its contexts anyway and the SFTP layer doesn't need
1735 know about it. Affected files lib/silcsft/silcsftp.h and
1736 lib/silcsftp/sftp_[server/client].c.
1738 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
1739 The SilcSimContext is not SilcSim.
1741 * Fixed possible buffer overflows in silc_id_render in the
1742 lib/silcutil/silcutil.c.
1744 * On EPOC the global crypto module lists are not used at all
1745 in the crypto library. Added support for using the constant
1746 algorithm list on EPOC. Affected files are
1747 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
1750 * Fixed the handling of third parameter of KICKED notify, since
1751 it was mistakenly updated to SILC Protocol 1.0 even though it
1752 is to be included in 1.1. Since it is not in 1.0 it is not
1753 mandatory, and this fix now handles it only if it is provided,
1754 and it is not error if it is not provided. Affected file
1755 lib/silcclient/client_notify.c.
1757 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1759 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
1760 client. Affected file irssi/src/silc/core/client_ops.c.
1762 * Merged with Irssi 0.8.4 from irssi.org CVS.
1764 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1766 * Check for valid socket connection in client entries before
1767 sending any messages. Fixes a crash, but doesn't fix some
1768 other underlaying bug that is lurking there. Affected
1769 file silcd/packet_send.c.
1771 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
1773 * $usermode, $cumode and $cumode_space expandos shouldn't do
1774 anything with non-SILC server records. Affected file
1775 irssi/src/silc/core/silc-expandos.c
1777 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1779 * Fixed the silc_net_check_[host/local]_by_sock to support
1780 IPv6 bound sockets as well. Now they can return IPv6 addresses
1781 as well. Affected file lib/silcutil/silcnet.c.
1783 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
1784 Affected lib/silcutil/unix/silcunixnet.c.
1786 * Fixed ID rendering (at least on some platforms, not NetBSD)
1787 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
1789 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1791 * Added silc_hash_public_key and silc_hash_public_key_compare
1792 functions to be used with SilcHashTable. They can be used to
1793 hash public keys and compare public keys in hash table. Affected
1794 file lib/silcutil/silcutil.[ch].
1796 * Added support for specifying multiple public keys for Client
1797 connection section in server configuration file. This makes it
1798 possible to accept multiple public keys from same host, or to
1799 make a section that accepts any incoming host, and have the
1800 accepted public keys listed in the section.
1802 Added functions silc_sever_[find/get]_public_key, added the
1803 support for this actually to all connection sections but only
1804 the Client section is currently allowed to specify multiple
1807 Affected files are silcd/server.c, server_internal.h,
1808 command.c, protocol.c, server_util.[ch], packet_receive.c.
1810 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1812 * Merged Irssi 0.8.2 from irssi.org CVS.
1814 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1816 * If silc_debug is TRUE, also output standard logging messages
1817 to stderr with the debug output.
1819 Made silc_log_reset_all() flushing all channels before returning.
1820 Also fixed some documentation typos.
1822 Affected files are lib/silcutil/silclog.[ch].
1824 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1826 * Fixed the server to check correctly the amount of connections
1827 from single host, by checking also the type of the connection.
1828 Fixed also the comparison of number of connections and number
1829 of allowed connections. Affected files are silcd/server.c,
1832 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1834 * Fixed the USERS command reply to save the user's mode on the
1835 channel as well. Fixed JOIN command reply to check whether a
1836 client is on channel already and not join it twice. Affected
1837 file lib/silcclient/command_reply.c.
1839 * Added new file silc-expandos.c into irssi/silc/core/ to return
1840 various stuff for various signal for the statusbar etc. updating.
1841 Now Irssi SILC client prints channel user modes etc. on the
1844 * The user mode (like server/router operator changes) is now shown
1845 on the Irssi SILC client's statusbar. The affected files are
1846 irssi/src/silc/core/client_ops.c, silc-expandos.c.
1848 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1850 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
1851 to SILC_SCHEDULE_[UN]LOCK macros.
1853 * Added more error printing to logs in server code. Affected
1854 files silcd/server.c and silcd/protocol.c.
1856 * Fixed -S option parsing in Irssi SILC Client. Affected file
1857 irssi/src/silc/core/silc-core.c.
1859 * Added silc_buffer_alloc_size function. Affected file is
1860 lib/silcutil/silcbuffer.h.
1862 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1864 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
1865 constants. Affected files in
1866 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
1869 * Changed the internal SFTP Memory FS table to const. Affected
1870 file lib/silcsftp/sftp_fs_memory.c.
1872 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1874 * Fixed the buffer formatting and unformatting routines to
1875 check the size of 64 bits types with sizeof(). Affected
1876 file is lib/silcutil/silcbuffmt.c.
1878 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1880 * Removed 0.6.x backwards support.
1882 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1884 * Changed all integer type names:
1885 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
1886 to avoid collisions with other libraries using same type names
1889 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1891 * Added `prefer_ipv6' argument to the functions
1892 silc_net_gethostbyname[_async]. If it is TRUE it will return
1893 IPv6 address over IPv4. If FALSE IPv4 address is returned
1894 even if IPv6 address was found. Affected files
1895 lib/silcutil/silcnet.[ch].
1897 * Added support silc_net_create_connection[_async] to fallback
1898 to IPv4 address if IPv6 address could not be used (like if
1899 it doesn't work on a specific system). Affected file in
1900 lib/silcutil/unix/silcunixnet.c.
1902 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1905 of the max tasks handling capabilities of the scheduler.
1906 Affected files lib/silcutil/silcschedule.[ch].
1908 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1910 * Added automatic extern "C" { ... } for C++ compilers so the
1911 application does not need to define them. Affected file
1912 includes/silcincludes.h.
1914 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
1915 old name went against naming convention. Applications now
1916 include "silcclient.h" instead of "clientlibincludes.h".
1917 Removed includes/clientlibincludes.h, it is redundant now.
1919 * Renamed includes/version.h to silcversion.h.
1921 * Added really preliminary support for OS/2 into the util
1922 library. Only thread & mutex API is implemented, others
1923 are still to be implemented. Created the lib/silcutil/os2/
1924 directory. Created also file includes/silcos2.h.
1926 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1928 * Added preliminary BeOS support into the util library.
1929 Created lib/silcutil/beos/, and implemented all the needed
1930 functions to support SILC on BeOS. Created also file
1931 includes/silcbeos.h.
1933 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
1935 * Added proper initializations to silc's irssi code, so it's
1936 now possible to load it as module. Affected files
1937 irssi/src/silc/core/silc-core.c,
1938 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
1940 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1942 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
1945 * Fixed the silcdoc document generator to correct generate
1946 docs from all kinds of filenames. Affected files are
1947 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1949 * ROBOdoc documented lib/silcutil/silcmemory.h.
1950 Added also new function silc_memdup.
1952 * Removed lib/silcutil/silcbufutil.h and moved those routines
1953 to the lib/silcutil/silcbuffer.h.
1955 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1957 * Added `user_count' to the SilcChannelEntry which now tells the
1958 number of users on the channel. The user count is now saved
1959 in normal server of global channels as well. Affected files
1960 silcd/server.c, idlist.h, packet_receive.c and command.c.
1962 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1963 include file utility functions.
1965 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1966 instead of calling directly OS routines.
1968 * Fixed NICK change printing in Irssi SILC Client. Fixed
1969 KICKED notify printing in Irssi SILC Client. Affected file
1970 irssi/src/silc/core/client_ops.c.
1972 * Fixed a NICK change bug in client library, to not recreate the
1973 client_entry->channels hash table everytime nick is changed.
1974 Affected file lib/silcclient/client.c.
1976 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1978 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1979 the SKE interface a bit.
1981 * Fixed padding problem in PKCS#1. The padding was not actually
1982 random since the random number generator was used incorrectly.
1983 This security bug affects only when encrypting with PKCS#1, and
1984 it is not currently used at all in SILC. SILC only use signing
1985 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1987 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1989 * Rewrote the notify handling in Irssi SILC client to not call
1990 the events as signals. Fixes problems with Perl support.
1991 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
1993 * Send the auto-nicking NICK command in client library with
1994 little timeout after connecting. The affected file is
1995 lib/silcclient/client.c.
1997 * Added following new config file settings:
1998 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1999 key_exchange_timeout, conn_auth_timeout, connections_max,
2002 Implemented all the new config settings handling in the server.
2004 Optimized the use of SKE Mutual flag usage. Use it only
2005 if connection authentication protocol is not based in public
2008 Renamed all SilcServerConfigSection* to SilcServerConfig*
2009 to have a bit shorter names.
2011 Affected files silcd/serverconfig.[ch], server.[ch], and
2014 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2016 * Cleaned up the listening sockets code, preparing for the rehash
2017 support. Affected file is silcd/server.c.
2019 * Fixed some output messages. Affected files are silcd/silcd.c,
2022 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2024 * Create lib/doc/silcrng_intro.html document as introduction
2025 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
2027 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2029 * Fixes to the silcd config template. Affected file is
2030 doc/example_silcd.conf.in.
2032 * Removed type casts from silc_calloc(), conforming to the
2033 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
2035 * Removed param_name member from client, server, and router
2036 section structs, now identifying the param directly.
2038 Added CONFIG_FREE_AUTH macro in config file parsing.
2040 Affected files are silcd/serverconfig.[ch].
2042 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
2044 * Fixed command line parameter handling. All SILC initialization
2045 is now done in silc_core_init() which also fixes autoconnecting
2048 Affected files irssi/src/silc/core/silc-core.c,
2049 irssi/src/fe-text/silc.c.
2051 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2053 * Added new configuration options and blocks:
2054 keepalive_secs, reconnect_count, reconnect_interval,
2055 reconnect_interval_max, reconnect_keep_trying and
2056 require_reverser_lookup. Added ConnectionParam block, and
2057 implemented the connection parameters when connecting as
2058 initiator and when accepting connections as responder.
2060 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
2061 whether given configuration value has been given already.
2063 Affected files silcd/serverconfig.[c], server.[c].
2065 * Splitted the doc/example_silcd.conf.in. Separated the crypto
2066 algorithm parts and created new file silcalgs.conf, that
2067 is now included from the example_silcd.conf.in.
2069 * Optimized the silc_server_connect_to_router_second to take
2070 the connection configuration object from the SilcServerConnection
2071 object instead of finding it during the connecting phase.
2072 Added the configuration object to SilcServerConnection struct.
2073 Affected files silcd/server_internal.h, server.c.
2075 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2077 * Add the client on channel after it was resolved at the
2078 channel message receiving, and it was not already on the
2079 channel. Affected file lib/silcclient/client_channel.c.
2081 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2083 * Fixed the public key authentication to allocate always the
2084 destination signature buffer instead of using static buffer.
2085 Affected file silcd/protocol.c.
2087 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2089 * Unified the serverconfig.[ch]'s helper function interface.
2090 Affected file silcd/serverconfig.[ch].
2092 * Removed doc/example_silc.conf.in since it is redundant.
2093 The make install will now install irssi/silc.conf file.
2095 * Added new Passphrase and Publickey authentication methods to
2096 config file, allowing both public key and passphrase based
2097 authentication to be set at the same time.
2099 Added `prefer_passphrase_auth' setting in config file which
2100 can be used to set to prefer passwd auth if both passwd and
2101 public key is set. If not set, public key is preferred.
2102 This has effect only when being initiator (responder will try
2105 Added support for authentication with passphrase and public key
2106 at the same time. The passphrase is tried first always since
2107 it is faster to check.
2109 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
2111 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2113 * Merged the new SILC Config library, with the server parsing
2114 support. Read the header file silcconfig.h or the toolkit
2115 documentation for the news. Affected files are
2116 doc/example_silcd.conf.in lib/silcutil/silcconfig.[ch]
2117 silcd/command.c silcd/packet_receive.c silcd/packet_send.c
2118 silcd/protocol.c silcd/server.c silcd/server_backup.c
2119 silcd/serverconfig.[ch] silcd/silcd.c.
2121 * Fixed some silclog documentation. Affected file is
2122 lib/silcutil/silclog.h.
2124 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2126 * The silc_cipher_register, silc_hash_register and
2127 silc_hmac_register now checks if the object to be registered
2128 is registered already. Affected files are
2129 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
2131 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

2137 * Allow zero length channel messages inside the Channel Message
2138 Payload. Affected file lib/silccore/silcchannel.c.
2140 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
2141 as header filenames.
2143 * Removed lib/silcclient/README and created HTML file
2144 lib/silcclient/silcclient_using.html, which is now included
2145 as part of Toolkit documentation.
2147 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2149 * Fixed CUMODE_CHANGE notify handling to change the mode of
2150 correct client. Affected file lib/silcclient/client_notify.c.
2152 * Make silc_rng_alloc fail if it cannot allocate the sha1
2153 hash algorithm. Affected file lib/silccrypt/silcrng.c.
2155 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2157 * Fixed the file transfer's key agreement payload to include
2158 zero port also if the hostname is NULL because it could not
2161 Call file transfer monitor callback now also if error occurs
2162 during key agreement protocol.
2164 Changed the silc_client_file_send interface to return the
2165 SilcClientFileError instead of session id. The session ID
2166 is returned into pointer provided as argument.
2168 Check that the file exists locally before sending the
2169 file transfer request at all.
2171 Affected file lib/silcclient/client_ftp.c, silcapi.h.
2173 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
2174 error than can occur while key agreement protocol. Affected
2175 file lib/silcclient/silcapi.h.
2177 * Fixed the event_mode CMODE handler to not crash when mode
2178 is changed and +k mode is set in the channel. Affected file
2179 irssi/src/silc/core/silc-channels.c.
2181 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
2182 SILC_LOG_WARNING to give out Warning and not Error. Affected
2183 file lib/silcutil/silclog.c.
2185 * Fixed the channel message payload decryption in the function
2186 silc_channel_message_payload_decrypt to not modify the original
2187 buffer before it is verified that the message decrypted
2188 correctly. Otherwise, next time it is called with correct
2189 channel key it won't encrypt since the payload is corrupted.
2190 Affected file lib/silccore/silcchannel.c.
2192 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2194 * Do not constantly resize the window. A fix patch by cras.
2195 Affected file irssi/src/fe-text/screen.c.
2197 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2199 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
2200 Affected file lib/silcutil/silcnet.c.
2202 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2204 * Fixed a bug in hash table internal routine for traversing
2205 the table with foreach callback. The current entry may
2206 become invalid in the callback but it was referenced after
2207 the callback returned.
2209 Do not allow auto rehashing of hash table during the
2210 silc_hash_table_foreach operation, for same reasons as it is
2211 not allowed for SilcHashTableList. Affected files are
2212 lib/silcutil/silchashtable.[ch].
2214 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2216 * Defined DLLAPI into silcincludes.h and silcwin32.h for
2217 Win32 DLL. extern's in header files are now declared with
2220 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2222 * Fixed private message handling. It used some old code that
2223 caused the client to crash. Affecte file is
2224 lib/silcclient/client_prvmsg.c.
2226 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2228 * Added function silc_client_add_channel,
2229 silc_client_replace_channel_id, and removed functions
2230 silc_client_new_channel_id and silc_idlist_get_channel_by_id
2231 from client library.
2233 * Added cross reference of the joined channels to the
2234 SilcClientEntry, and changed the SilcChannelEntry's
2235 users list to SilcHashTable. The affected files are
2236 lib/silcclient/idlist.[ch].
2238 * Fixed a bug in hash table tarversing. While the hash table
2239 is traversed with SilcHashTableList the table must not be
2240 rehashed. It is now guaranteed that auto rehashable tables
2241 are not rehashed while tarversing the list. Also defined that
2242 silc_hash_table_rehash must not be called while tarversing
2243 the table. Added function silc_hash_table_list_reset that must
2244 be called after the tarversing is over. The affected files are
2245 lib/silcutil/silchashtable.[ch].
2247 * Changed all hash table traversing to call the new
2248 silc_hash_table_list_reset in server and in client library.
2250 * Added function silc_client_on_channel to return the
2251 SilcChannelUser entry if the specified client entry is joined
2252 on the specified channel. This is exported to application as
2253 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
2255 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2257 * Fixed founder regaining problem with JOIN command on normal
2258 server. The notify for mode change must be sent always and
2259 not only if !cmd->pending. Affected file silcd/command.c.
2261 * Fixed the WHOWAS command's reply sending to support the
2262 lists correctly. Affected file silcd/command.c.
2264 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2266 * When sending JOIN command to router for processing the
2267 sender's old command identifier was not saved back to the
2268 sender's command context, fixed now. The affected file is
2271 * Create the key in JOIN command of the router did not return
2272 the channel key, added check for this. Affected file is
2275 * Fixed a channel ID update bug in JOIN command reply. Do
2276 not directly upgrade the ID but call the function
2277 silc_idlist_replace_channel_id if the ID was changed.
2278 Affected file silcd/command_reply.c.
2280 * Fixed memory leaks from command calling if it would fail.
2281 Affected file silcd/command.c.
2283 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2285 * Applied patches from cras:
2287 Memory leak fixes around libaries, irssi window resize fix,
2288 new silclist.h and silcdlist.h, all extern inline changed to
2291 * Removed dotconf from lib/dotconf, not needed anymore.
2293 * Removed TRQ from lib/trq, not needed anymore.
2295 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
2296 with server connections. Later this will be configurable
2297 in config file after new config file is done. Affected file
2300 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
2302 * Fixed a crash in server related to channel announcements.
2303 Affected file silcd/server.c.
2305 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2307 * Fixed memory leaks in silc_server_create_new_channel*
2308 functions. Affected file silcd/server.c.
2310 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
2311 which ID was changed. This way the router will send the
2312 user list for the channel again, and server won't be in
2313 desync in some rare circumstances. Affected file is
2314 silcd/packet_receive.c.
2316 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2318 * Check for NULL socket pointer in the function
2319 silc_server_packet_send_to_channel_real. Affected file
2320 silcd/packet_send.c.

2323 list. Affected file silcd/packet_receive.c.
2325 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2327 * Fixed some header addition to Toolkit distribution in
2328 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
2330 * Added lib/silcclient/client_ops_example.h as an template
2331 file for application programmers to quickly start using
2332 the SilcClientOperation functions in their application.
2333 Updated the lib/silcclient/README as well to tell about this
2334 nice file made available.
2336 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2338 * Call silc_server_remove_from_channels when removing client
2339 entry when NO_SUCH_CLIENT_ID was received. Affected file
2340 is silcd/command_reply.c.
2342 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2344 * Added server & router operator statistics updating. Affected
2345 file silcd/packet_receive.c and silcd/command.c.
2347 * Fixed the SERVER_SIGNOFF notify handling on normal server
2348 not to save the history information for clients. Same was
2349 fixed earlier in remove_clients_by_server function, but not
2350 here. Affected file silcd/packet_receive.c.
2352 * Raised the default connection-retry count from 4 to 7 in
2353 server. Affected file silcd/server.h.
2355 * Cancel any possible reconnect timeouts when we start the
2356 key exchange. Affected file silcd/server.c.
2358 * Do not reconnect on connection failure when SCONNECT was
2359 given. Affected files silcd/server.[ch].
2361 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2363 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
2365 * Fixed the NICK command to always give the unformatted
2366 nickname to the one giving the NICK command. If unformatted
2367 nickname is cached already it will be formatted and the
2368 local entry will always get the unformatted nickname.
2369 Affected file lib/silcclient/idlist.c.
2371 * Fixed some double frees from client library commands.
2372 Affected file is lib/silcclient/command.c.
2374 * Fixed CUMODE command in server to assure that no one can
2375 change founder's mode than the founder itself, there was a
2376 little bug. Affected file silcd/command.c.
2378 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2380 * Removed the SilcClientCommandDestructor from the client
2381 libary, it is not needed anymore. Affected files are
2382 lib/silcclient/silcapi.h, command[_reply].[ch],
2383 client_notify, idlist.c.
2385 * Fixed GETKEY command to first resolve client, and then
2386 resolve the server only if the client was not found, instead
2387 of resolving both at the same time. Affected file is
2388 lib/silcclient/command.c.
2390 * Added silc_client_start_key_exchange_cb and lookup the
2391 remote hostname and IP address before starting the key
2392 exchange with server. The affected file is
2393 lib/silcclient/client.c.
2395 * The server's public key is now saved using the IP address
2396 of the server and not the servername for the filename.
2397 The hostname public key filename is checked as an fall back
2398 method if the IP address based filename is not found.
2400 Fixed the GETKEY command to save the fetched server key
2401 in correct filename.
2403 Print the remote server's hostname now when new key is
2404 received during connection process. Affected file is
2405 irssi/src/silc/core/client_ops.c.
2407 * Return always our own public key to the client if it asks
2408 for it with GETKEY command. Affected file silcd/command.c.
2410 * Removed the use_auto_addr variable from default config
2411 file since it was in wrong section. Affected file is
2414 * Fixed TOPIC_CHANGE notification to not route it when it
2415 was sent using silc_server_send_notify_to_channel function.
2416 Affected file silcd/command.c.
2418 * Fixed silc_server_send_notify_kicked to send the kicker's
2419 Client ID also, it was missing. Affected files are
2420 silcd/command.c, silcd/packet_send.[ch].
2422 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2424 * Do not save client history information in SERVER_SIGNOFF.
2425 Fixes the bug in normal server that it does not detect
2426 the client becoming valid after the server becomes back
2427 online. Affected file silcd/server_util.c.
2429 * Added `sock_error' field into the SilcSocketConnection
2430 context. When error occurs during socket operation (read
2431 or write) the error is saved. Added also new function
2432 silc_socket_get_error to return human readable socket error
2433 message. Affected files are lib/silcutil/silcsockconn.[ch],
2434 lib/silcutil/unix/silcunixsockconn.c, and
2435 lib/silcutil/win32/silcwin32sockconn.c.
2437 * The server now prints the socket error message in the
2438 signoff for client. Affected file silcd/server.c.
2440 * Fixed the `created' channel information sending from router
2441 to server in JOIN command. Checks now whether the channel
2442 really was created or not and set it according that.
2444 Fixed the JOIN command to use the client entry's current
2445 ID during the joining procedure instead of the one it sent
2446 in the command (it is checked though), since it can change
2447 between the packet processing and command processing, and
2448 would just case unnecessary pain in the client end. Affected
2449 file silcd/command.c.
2451 * Fixed a channel key payload sending to use correct channel
2452 ID when the server was forced to change the channel's ID by
2453 router. Router sent the key payload with the old Channel ID.
2454 Affected file silcd/packet_receive.c.
2456 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2458 * Call silc_server_save_channel_key only if the key payload
2459 was provided in the JOIN command's command reply. Affected
2460 file silcd/command_reply.c.
2462 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2464 * Fixed silc_mp_sizeinbase to return the value correctly with
2465 MPI. Affected file lib/silcmath/mp_mpi.c.
2467 * Fixed the stop_server signal to correctly stop the scheduler
2468 and gracefully stop the server when SIGTERM or SIGINT signals
2469 are received. Affected file silcd/silcd.c.
2471 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
2473 * Simple handling of TERM and HUP signals. Also added some log
2474 flushing call around. Affected file is
2477 * Fixed small bugs in silclog.c. Now buffering output will take
2478 effect after 10 seconds since startup: This will ensure that
2479 no important startup messages are lost. Also output redirection
2480 will preserve original format ([Date] [Type] message).
2481 Affected file is lib/silcutil/silclog.c.
2483 * Added two options to the config file, in the logging section:
2484 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
2485 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
2487 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2489 * Do not print the warning about log files not being initialized
2490 more than once to avoid excess logging. Affected file is
2491 lib/silcutil/silclog.c.
2493 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
2494 the SIM copying in make install in Makefile.am.pre.
2496 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2498 * Rewritten silclog APIs. Globally interesting changes follows:
2499 silc_log_set_files() changed to silc_log_set_file().
2500 silc_log_set_callbacks() changed to silc_log_set_callback().
2501 ROBOdoc documented silclog header file.
2502 SilcLogCb now returns bool to wether inihibit the default
2503 handler or not (to keep the old behaviour return always TRUE).
2504 The new APIs should also fix the problem of the
2505 silcd_error.log file that was written in the current directory.
2508 Log files streams will remain opened after silc_log_set_file()
2509 call, means less CPU usage notably on high traffic servers.
2510 File streams are now full buffered, and flushed to the disk
2511 every 5 minutes, lesses HD activity and CPU usage.
2512 Messages can be redirected, allowing admins to configure
2513 one single logfile for all server messages.
2514 the silc_log_quick global variable to activate fast-logging.
2515 Affected files lib/silcutil/silclog.[ch]
2517 * Changed some code to conform new silclog APIs. Affected
2518 files are doc/example_silcd.conf.in, silcd/server.c
2519 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
2522 * Fixed a memory leak that could occur in some situations.
2523 Affected file silcd/serverconfig.c.
2525 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2527 * Added the silc_client_del_client to remove the client from
2528 all channels as well. Affected file lib/silcclient/idlist.c.
2530 * Fixed the client library to correctly remove the client
2531 from all channels when the client entry is being destroyed.
2532 Affected file lib/silcclient/client_notify.c, command.c.
2534 * Added auto-nicking support to the client library. If the
2535 applicatio now sets client->nickname it will be sent to the
2536 server after connecting by the library. This way for example
2537 SILCNICK (or IRCNICK) environment variables will have effect
2538 and always change the nickname automatically to whatever
2539 it is wanted. Affected file lib/silcclient/client.[ch].
2541 * Renamed silc_server_command_bad_chars to the
2542 silc_server_name_bad_chars and moved it to the
2543 silcd/server_util.[ch]. Added also new function
2544 silc_server_name_modify_bad to return nickname that
2545 includes bad characters as new nickname without those
2546 bad characters. This check and modify is now used in
2547 silc_server_new_client when the username is initially set
2548 as nickname, so it must be checked to be valid nickname.
2549 Affected file silcd/packet_receive.c.
2551 * The nickname length is now taken from the packet for real
2552 and not trusted to strlen() since it clearly can return
2553 wrong length for nickname including bad characters. This
2554 also applies to channel names. Affected file silcd/command.c.
2556 * Removed the lib/silcsilm/modules directory. Modules are now
2557 compiled into the lib/silcsim. Fixed the copying of the
2558 modules to follow symbolic links in Makefile.am.pre.
2560 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
2562 * Fixed silc_string_regexify list creation. Fixes bugs with
2563 BAN and INVITE commands in server. The affected file is
2564 lib/silcutil/unix/silcunixutil.c.
2566 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2568 * Removed the command destructor entirely from the server's
2569 command and command reply routines. It is not needed, and
2570 its usage was buggy and caused crashes. Affected files are
2571 silcd/command[_reply].[ch].
2573 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2575 * Cancel protocol and NULL sock->protocol if timeout
2576 occurred during protocol. Affected file silcd/server.c.
2578 * Cancel protocol timeouts always before calling the final
2579 callback, to assure that after final callback is called
2580 no other state will be called for the protocol anymore.
2581 Affected file silcd/protocol.c.
2583 * Print error log if incoming connection configuration could
2584 not be found. Affected file silcd/server.c.
2586 * Fixed JOIN command to correctly save the founder mode
2587 to the client on normal SILC server, when the channel
2588 was created by the router. Affected file silcd/command.c.
2590 * Fixed LIST command (hopefully) to send correct reply
2591 packets. Affected file silcd/command.c.
2593 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2595 * The silc_packet_receive_process now returns FALSE if the
2596 read data was invalid packet, and TRUE if it was ok.
2598 The server now checks that if unauthenticated connection
2599 sends data and its processing fails the server will close
2600 the connection since it could be a malicious flooder.
2602 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
2604 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2606 * Make sure the warning about error opening a log file is
2607 printed only once and not everytime it fails (produces
2608 too much useless log). Affected file lib/silcutil/silclog.c.
2610 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2612 * Made the silc_server_daemonise() function more readable.
2613 Affected file silcd/server.c.
2615 * Pid file is now optional, the user may comment it out from
2616 the config file. Removed define SILC_SERVER_PID_FILE, we
2617 don't need a default any longer. Affected file
2618 configure.in.pre, lib/Makefile.am.pre.
2620 * Make some use of the pid file. The server now dies at startup
2621 if it detects a valid pid file on his path. The server would
2622 die anyway in this circumstance, because of the bind() failure.
2623 Affected file silcd/silcd.c.
2625 * No longer compiling lib/dotconf.
2627 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2629 * Fixed JOIN command parsing not to crash. Affected file
2630 lib/silcclient/command.c.
2632 * Fied the NICK_CHANGE notify to add the new client entry
2633 even it is resolved. This removes an <[unknown]> nick
2634 thingy bug in the client. Affected file is
2635 lib/silcclient/client_notify.c.
2637 * Do not try to allocate 0 bytes (efence does not like it)
2638 in lib/silccore/silccomand.c when encoding payload.
2640 * Do not take IRCNICK as nickname in Irssi SILC client since
2641 it is not possible to set nickname before hand connecting
2642 the server (TODO has an entry about adding auto-nicking
2645 * Changed the silc_server_command_pending to check whether
2646 there already exists an pending entry with the specified
2647 command, command identifier and pending callback. This is
2648 to fix IDENTIFY and WHOIS related crashes that may register
2649 multiple pending commands with same identifier. Affected
2650 file silcd/command.c.
2652 * Fixed the server to reconnect to the router even if it
2653 was already reconnecting and EOF was received. This to
2654 fix a possibility that the server wouldn't ever try to
2655 auto-reconnect to the router. Affected file silcd/server.c.
2657 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2659 * Fixed the server's password authentication to use the
2660 length of the locally saved password, and not the one
2661 sent in the packet. Affected file silcd/protocol.c.
2663 * Fixed same password authentication problem in the
2664 Authentication Payload handling routines in
2665 lib/silccore/silcauth.c.
2667 * Yet another password authentication problem fixed with
2668 channel password handling in silcd/command.c.
2670 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2672 * If first character of string in silc_parse_userfqdn is '@'
2673 then do not parse it. Affected file is
2674 lib/silcutil/silcutil.c.
2676 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2678 * Fixed minor bug in IDENTIFY command reply sending, which
2679 caused various weird problems during JOIN when it was
2680 resolving names for users. Affected file silcd/command.c.
2682 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2684 * Fixed the IDENTIFY command reply sending to chech better valid
2685 clients. It was possible to send incomplete list of replies.
2686 Affected file silcd/command.c.
2688 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2690 * Added silc_client_command[s]_[un]register functions now to
2691 dynamically register the commands in client library. Removed
2692 the static table of commands. This allows the client library
2693 to call commands without causing the application to know about
2694 what commands library has called.
2696 Removed the INFO command reply kludge to detect when the command
2697 was called by library. Now library use its own command reply
2698 function for INFO command.
2700 Added function silc_client_command_call to call a command.
2701 Application can use it to call command, not access the structure
2704 Now all commands that are sent by the client library (not
2705 explicitly sent by application) use own command reply functions.
2707 Affected files around lib/silcclient/ and in
2708 irssi/src/silc/core/.
2710 * Fixed the WHOIS command reply sending to chech better valid
2711 clients. It was possible to send incomplete list of replies.
2713 Fixed the WHOIS and IDENTIFY to send the request to router
2714 if normal server did not do it and did not find any results.
2716 Affected file silcd/command.c.
2718 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2720 * Moved the internal data from SilcClient context into its
2721 own file, not accesible to application. Affected files
2722 lib/silcclient/client.h and lib/silcclient/client_internal.h,
2723 and other files in client library.
2725 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2727 * Added doc/examples installation target in Makefile.am.pre.
2730 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2732 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
2733 commands the found client entry will be removed from the
2734 cache, after notifying application about the error. Affected
2735 file lib/silcclient/command_reply.c.
2737 * Changed the /MSG to check for exact nickname user gave, and
2738 not let `nick' match `nick@host' if it is only one found. Now,
2739 user must type the exact nickname (like nick@host2) even if
2740 there are no more than one same nicks found. This is to avoid
2741 a possibility of sending nickname to wrong nickname since
2742 `nick' could match `nick@host'. Affected file is
2743 irssi/src/core/silc-servers.c.
2745 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2747 * Do not print "you are now server operator" or similar when
2748 giving /away command. Affected files are
2749 irssi/src/silc/core/client_ops.c, silc-servers.h.
2751 * Made the silc_server_command_pending_error_check to send
2752 the same command reply payload it received back to the
2753 original sender of the command. This way all arguments
2754 that was received by the server will be received by the
2755 client too. Affected file silcd/command.c.
2757 * Added the silc_idcache_add to return the created cache entry
2758 to a pointer. Affected file lib/silccore/silcidcache.[ch].
2760 * Add global clients to expire if they are not on any channel.
2761 This is because normal server will never know if they signoff
2762 if they are not on any channel. The cache expiry will take
2763 case of these entries. This is done by normal servers only.
2764 The affected files are silcd/command_reply.c,
2765 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
2767 * If server receives invalid ID notification for WHOIS or
2768 IDENTIFY and the ID exists in the lists, it is removed.
2769 Affected file silcd/command_reply.c.
2771 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
2772 in client then client entry that it matches is searched and
2773 the nickname is printed on the screen for user. Affected
2774 file irssi/src/silc/core/client_ops.c.
2776 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2778 * Use cache entry expire time in the LIST command reply to
2779 purge old entries from the cache after the LIST command
2780 reply has been received. This way we don't have non-existent
2781 entries in the cache for too long. Affected file is
2782 silcd/command_reply.c.
2784 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2786 * If we are normal server, and we've not resolved client info
2787 in WHOIS or IDENTIFY from router, and it is global client,
2788 we'll check whether it is on some channel. If it is not
2789 then we cannot be sure about its validity and will resolve it
2790 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
2791 file silcd/command.c.
2793 * Search channel by name (if possible) rather than by ID
2794 in IDENTIFY command's command reply. Affected file is
2795 silcd/command_reply.c.
2797 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2799 * Distribute to the channel passphrase in CMODE_CHANGE notify.
2800 Updated specs and implemented it. Affected file silcd/command.c,
2801 silcd/packet_send.c and silcd/packet_receive.c.
2803 * Implemented the <founder auth> payload handling in the JOIN
2804 command. If provided all conditions for channel joining
2805 except requirement to provide correct passphrase can be
2806 overrided by the channel founder. Updated the protocol specs.
2807 Affected file silcd/command.c.
2809 Added support for founder auth in JOIN command in client
2810 library. Fixed the parsing of the JOIN command now to support
2811 all options as they should be. The affected file is
2812 lib/silcclient/command.c.
2814 * Optimized the WHOIS and IDENTIFY commands to send the request
2815 to router only if it includes nicknames or other names. If
2816 they include only IDs then check the local cache first before
2817 routing. Affected file is silcd/command.c.
2819 * Added channels topic announcements. Affected file is
2820 silcd/packet_receive.c and silcd/server.c.
2822 * Fixed the silc_server_send_notify_topic_set to really destine
2823 the packet to channel. Affected file silcd/packet_send.c.
2825 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
2826 library. Affected file lib/silcclient/client_notify.c.
2828 * Added UMODE announcements. Affected file silcd/server.c.
2830 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2832 * Memory leak fixes in:
2834 lib/silcutil/silcsockconn.c
2835 lib/silcske/silcske.c
2836 lib/silcske/groups.c
2838 lib/silccrypt/silcpkcs.c
2839 lib/silccore/silccommand.c
2840 lib/silccore/silcidcache.c
2845 * ROBOdoc documented the lib/silcske/groups.h file and a
2846 bit changed the interface for better.
2848 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2850 * Update the client entry context in the ID cache after
2851 nick change. Affected file lib/silcclient/command.c.
2852 Fixes the CUMODE command when regaining founder privileges,
2853 and a little WHOIS problem.
2855 * Fixed silc_net_gethostbyname to correctly call the
2856 inet_ntop. Affected file lib/silcutil/silcnet.c.
2858 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2860 * Added IPv6 support checking to the configure.in.pre, added
2861 also --enable-ipv6 option to override the check. Affected
2862 file configure.in.pre.
2864 * The silc_thread_create now calls the start function
2865 directly if threads support is not compiled in. Removes
2866 ugly #ifdef's from generic code. Affected files are
2867 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
2869 * Added silc_net_gethostby[name/addr]_async to asynchronously
2870 resolve. Affected files are lib/silcutil/silcnet.[ch].
2872 * Added support for rendering IPv6 based server, client and
2873 channel IDs. Affected file lib/silcutil/silcutil.c.
2875 * Added support for creating IPv6 based server IDs. Affected
2876 file is silcd/serverid.c.
2878 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2880 * Added silc_net_gethostby[addr/name] into the
2881 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
2882 routines. Added silc_net_is_ip[4/6]. Affected file is
2883 lib/silcutil/unix/silcunixnet.c. All routines that take
2884 address as argument now supports both IPv4 and IPv6 addresses.
2886 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
2888 * Fixed LIST command reply sending in server. Affected file
2891 * Server now sends the kicker's client ID in the KICK notify
2892 to the kicked client. Affected file silcd/command.c.
2894 * The client library now parses the kickers client ID and
2895 UI displays it. Affected files lib/silcclient/client_notify.c
2896 and irssi/src/silc/core/silc-channels.c, module-formats.c.
2898 * Made all payload parsing function prototypes consistent.
2899 They all take now const unsigned char * and uint32 pair as
2900 the payload data instead of SilcBuffer. Changes all around
2901 the source tree. Other unsigned char* -> const unsigned char*
2902 changes around the tree as well.
2904 * Optimized SFTP client and server packet sending not to
2905 allocate new buffer for each packet but to recycle the
2906 first allocated buffer. Affected files are
2907 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
2909 * Optimized the SFTP client to use SilcList instead of
2910 SilcDList for requests, because it is faster. Affected file
2911 is lib/silcsftp/sftp_client.c.
2913 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
2914 into lib/silccore/silcid.[ch].
2916 Renamed silcpayload.[ch] into silcargument.[ch].
2918 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
2920 * If client entry is deleted with active key agreement
2921 session, abort the session.
2923 The silc_client_abort_key_agreement now calls the completion
2924 callback with new SILC_KEY_AGREEMENT_ABORTED status.
2926 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
2929 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2931 * Don't use __restrict in older GCC's. Affected file is
2932 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
2934 * silc_net_localhost now attempts to reverse lookup the
2935 IP/hostname. Affected file lib/silcutil/silcnet.c.
2937 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
2938 command. It can be used to gain founder privileges at
2939 the same time when joining the channel.
2941 Defined that the SILC_NOTIFY_TYPE_KICKED send the
2942 kicker's client ID as well. Updated protocol specs.
2944 Defined that the server must send SILC_COMMAND_IDENTIFY
2945 command reply with error status to client who sent
2946 private message with invalid client ID.
2948 Updated the protocol specification.
2950 * Added silc_server_send_command_reply to send any
2951 command reply. Affected file silcd/packet_send.[ch].
2953 * Added silc_id_payload_encode_data to encode ID payload
2954 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2956 * The server now send IDENTIFY command reply with error
2957 status if client ID in private message is invalid. Affected
2958 file silcd/packet_receive.c.
2960 * Save the server key file with server's IP address in
2961 the filename instead of hostname. The affected file is
2962 irssi/src/silc/core/client_ops.c.
2964 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2966 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2969 * Added libtool support for compiling shared objects in
2970 lib/silcsim. Affected file configure.in.pre and
2971 lib/silcsim/Makefile.am. Original patch by cras.
2973 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2975 * Pid file configuration, and server's config file fixes
2976 patch by toma. Updated CREDITS file.
2978 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2980 * Fixed silc_client_channel_message to not try to decrypt
2981 the message twice if it resolved the destination client
2982 information. This could cause of dropping one channel
2983 message. Affected file lib/silcclient/client_channel.c.
2985 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2987 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2988 lib/silcclient/client.c. This function is used when the SILC
2989 Client is run under some other scheduler, or event loop or
2990 main loop. On GUI applications, for example this may be
2991 desired to used to run the client under the GUI application's
2992 main loop. Typically the GUI application would register an
2993 idle task that calls this function multiple times in a second
2994 to quickly process the SILC specific data.
2996 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2998 * Fixed silc_server_drop() for dropping the supplementary
2999 groups as well, this could cause a security hole on some
3002 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3004 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
3007 * Write PID file after dropping privileges. Added -F option
3008 to run server on foreground. A patch by debolaz.
3009 Affected files silcd/server.c, silcd/silcd.c.
3011 * Fixed MOTD to return the MOTD file server name. Affected
3012 file silcd/command.c.
3014 * Added INFO command reply handling to the Irssi SILC Client.
3015 Affected file irssi/src/silc/core/client_ops.c.
3017 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3019 * Fixed the silc_idcache_list_* routines to really support
3020 the dynamic list. Fixes a crash. Affected file is
3021 lib/silccore/silcidcache.c.
3023 * Fixed the LIST command reply to really call LIST command's
3024 pending callbacks. Affected file silcd/command_reply.c.
3026 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3028 * Update conn->local_entry->nickname after giving NICK
3029 command. Affected file lib/silcclient/command.c.
3031 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
3033 * Added the [pid] option to the silcd configuration file
3035 Affected files: serverconfig.[ch] and silcd.c
3037 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3039 * Save fingerprint in WHOIS command reply in server.
3040 Affected file silcd/command_reply.c.
3042 * Fixed NICK commands pending callback registration.
3043 Affected file lib/silcclient/command.c.
3045 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3047 * Use ++server->cmd_ident when sending commands in server,
3048 instead of random number. Affected file silcd/command.c.
3050 * Fixed GETKEY command reply to call actually GETKEY pending
3051 command callbacks. Affected file silcd/command_reply.c.
3053 * A bit stricter check for nicknames. Check for same nickname
3054 in NICK command also. Affected file silcd/command.c.
3056 * Do not call INFO command everytime client ID changes, only
3057 during first connecting. Affected file lib/silcclient/client.c.
3059 * Set the new nickname only after successful command reply for
3060 NICK command is returned by server. Affected file
3061 lib/silcclient/command.c.
3063 * Remove nicknames from nicklist during server_signoff notify.
3064 Should fix /NAMES bit more. The affected file is
3065 irssi/src/silc/core/silc-channels.c.
3067 * Added `fingerprint' field to the SilcIDListData in the
3068 silcd/idlist.h to hold the fingerprint of the client's
3071 Send the fingerprint of the client's public key in WHOIS
3074 Affected files silcd/command.c, and silcd/idlist.[ch].
3076 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
3077 create fingerprint from given data.
3079 * Show the fingerprint of the client's public key in WHOIS.
3080 Affected files irssi/src/module-formats.[ch] and
3081 irssi/src/silc/core/client_ops.c.
3083 * Format the multiple same nicknames also during JOIN and
3084 NICK_CHANGE notifys. Affected file is
3085 lib/silcclient/client_notify.c.
3087 * Do not print error on screen for invalid private message
3088 payload since it can come if someone is sending private
3089 messages with wrong key. Affected file
3090 lib/silccore/silcprivate.c.
3092 * Fixed multiple concurrent /PING crash. Affected file
3093 lib/silcclient/command.c.
3095 * Changed the wrong ID encoding. All IP addresses must be
3096 in MSB first order in encoded format. They were encoded
3097 wrong and was in LSB format. Affected files are
3098 silcd/serverid.c, lib/silcutil/silcutil.c.
3100 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
3102 * Call the `connect' client operation through the scheduler
3103 in case of error. Affected file lib/silcclient/client.c.
3105 * Call the `failure' client operation even if the error
3106 occurred locally during a protocol. Affected file is
3107 lib/silcclient/protocol.c.
3109 * Added support of sending LIST command to router from normal
3110 server. This way normal server can get list of all channels
3111 in the network too. Fixed the channel list sending in the
3112 server too. Affected files are silcd/command.c, and
3113 silcd/command_reply.[ch].
3115 * Added silc_server_update_channels_by_server and
3116 silc_server_remove_channels_by_server. They are used during
3117 disconnection of primary router and in backup router protocol.
3118 Affected file silcd/server_util.[ch], silcd/server.c and
3119 silcd/server_backup.c.
3121 * Fixed channel adding to global list in IDENTIFY command
3122 reply in server. Affected file silcd/command_reply.c.
3124 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3126 * If the incoming packet type is REKEY or REKEY_DONE process
3127 that packet always synchronously. Fixes yet another MAC
3128 failed error on slow (dialup) connections. Affected file
3129 lib/silcclient/client.c and silcd/server.c.
3131 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3133 * Call check_version SKE callback for initiator too. Affected
3134 file lib/silcske/silcske.c.
3136 * Implemented fix for security hole found in the SKE that was
3137 fixed in the specification few days back; the initiator's
3138 public key is now added to the HASH value computation.
3139 Added backwards support for the old way of doing it too, for
3140 old clients and old servers. Affected file is
3141 lib/silcske/silcske.c.
3143 * Enabled mutual authentication by default in SKE. If initiator
3144 is not providing mutual authentication the responder will
3145 force it. This will provide the proof of posession of the
3146 private key for responder. The affected files are
3147 lib/silcclient/protocol.c and silcd/protocol.c.
3149 * Do not cache anymore the server's public key during SKE.
3150 We do mutual authentication so the proof of posession of
3151 private key is done, and if the server is authenticated in
3152 conn auth protocol with public key we must have the public
3153 key already. Affected file silcd/protocol.c.
3155 * Added new global debug variable: silc_debug_hexdump. If
3156 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
3157 file lib/silcutil/silclog.[ch].
3159 * Fixed compilation warning due to char * -> const char *.
3160 Affected files lib/silcutil/silcnet.h, and
3161 lib/silccore/silcauth.[ch].
3163 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3165 * Fixed CMODE command when new channel key was created. If
3166 the creation failed the old key was removed. Next time giving
3167 same command would crash the server since the old key was
3168 freed already. Affected file silcd/command.c.
3170 * Fixed the silc_server_announce_get_channels to not crash
3171 on reconnect. Affected file silcd/server.c.
3173 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3175 * Added silc_log_set_debug_string function to set a regex
3176 string to match for debug output. Only the function names,
3177 or filenames matching the given debug string is actually
3178 printed. This way it is possible to filter out those debug
3179 strings that user is not interested in.
3181 Fixed a bug in silc_string_regexify.
3183 Affected files lib/silcutil/silclog.[ch], and
3184 lib/silcutil/unix/silcunixutil.c.
3186 * Changed the -d options in both server and Irssi SILC client
3187 to take the debug string as argument. Affected files
3188 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
3190 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3192 * Added silc_hash_babbleprint to create a Bubble Babble
3193 Encoded fingerprint. The encoding is developed by Antti
3194 Huima (draft-huima-babble-01.txt), and it creates human
3195 readable strings out of binary data. Affected file
3196 lib/silccrypt/silchash.[ch].
3198 * Print the babble print now in addition of fingerprint as well
3199 in Irssi SILC client. Affected files are
3200 irssi/src/fe-common/silc/module-formats.[ch],
3201 irssi/src/fe-common/silc/core/client_ops.c.
3203 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3205 * Fixed a security problem found in SKE. The initiator's
3206 public key too is now added to the HASH hash value creation
3207 which is signed by the responder to create the SIGN value.
3208 This will prevent anyone in the middle to lie to the responder
3209 about the initiator's public key. If this is done now, the
3210 man in the middle will get caught. Updated the protocol
3213 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3215 * Better installation directory handling. Configure module
3216 paths and other paths automatically to example_silc* files
3217 in doc/. A patch by toma.
3219 * Fixed compiler warning from MPI library, and from SILC RNG.
3222 * Added SILC_SERVER_PID_FILE to define the pid file for server.
3223 It can be configured with ./configure. A patch by toma.
3225 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3227 * Find correct make to use in prepare-clean. A patch by
3228 toma. Affected file prepare-clean.
3230 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
3232 * Added irssi variables use_auto_addr, auto_bind_ip,
3233 auto_bind_port and auto_public_ip.
3235 * Changed the interface for silc_client_send_key_agreement
3236 in lib/silcclient/silcapi.h
3240 irssi/src/silc/core/silc-core.c
3242 lib/silcclient/silcapi.h
3243 irssi/src/silc/core/silc-channels.c
3244 lib/silcclient/client_keyagr.c
3247 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
3249 * Added silc_pkcs_public_key_compare to compare two
3250 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
3252 * Check that the client who set the founder mode on the
3253 channel is the same client that is giving the founder
3254 mode to itself. It is done by comparing the saved public
3255 key (it is saved even in the authentication is passphrase).
3256 Affected file silcd/command.c.
3258 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3260 * Do not process packet for disconnected socket connection.
3261 Affected file lib/silccore/silcpacket.c.
3263 * Process the DISCONNECT packet through scheduler in the
3264 client library. Affected file lib/silcclient/client.c.
3266 * Fixed the silc_client_packet_parse to not to increase
3267 the packet sequence number if the conn->sock and the
3268 current socket connection is not same. This can happen
3269 for example during key agreement when the conn includes
3270 multiple socket connections (listeners). Affected file
3271 lib/silcclient/client.c.
3273 * The sender of the file transfer request now provides also
3274 the pointer (listener) for the key exchange protocol. If
3275 the listener cannot be created then it sends empty key
3276 agreement and lets the receiver provide the listener.
3278 Added `local_ip' and `local_port' arguments to the
3279 silc_client_file_send. If they are provided they are used,
3280 if not then it will attempt to find local IP address, if
3281 not found or bind fails then the remote client will provide
3284 Affected files are lib/silcclient/client_ftp.c and
3285 lib/silcclient/silcapi.h.
3287 * Extended the FILE SEND command to support defining the
3288 local IP and port for key exchange listener. They are
3289 optional. Affected file irssi/src/silc/core/silc-servers.c.
3291 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3293 * Defined to WHOIS command reply the sending of fingerprint
3294 of the client's public key (if the proof of posession of the
3295 corresponding private key is verified by the server).
3296 Updated to the protocol specification.
3298 * Added support of receiving the client's public key's
3299 fingerprint in command reply in client library. Affected
3300 file is lib/silcclient/command_reply.c, and
3301 lib/silcclient/idlist.[ch].
3303 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3305 * Do not send over 128 chars long nickname to the server
3306 in NICK command. Affected file lib/silcclient/command.c.
3308 * Do not send over 256 chars long channel names to the server
3309 in JOIN command. Affected file lib/silcclient/command.c.
3311 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3313 * Assure that silc_server_close_connection cannot be called
3314 twice for same socket context. Affected file is
3317 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3319 * Send error message to application if opening file for
3320 writing during file transfer fails. Affected file is
3321 lib/silcclient/client_ftp.c.
3323 Remove all file transfer sessions for a client that we're
3324 removing from ID cache.
3326 Affected file is lib/silcclient/client_ftp.c.
3328 * Fixed silc_net_addr2bin to return correct address. Affected
3329 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3331 * Fixed file transfer session removing on signoff notify.
3332 Affected file irssi/src/silc/core/silc-servers.c.
3334 * Added the SilcClientFileError to be returned in the monitor
3335 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
3336 Affected file lib/silcclient/silcapi.h.
3338 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3340 * Fixed a crash in silc_client_ftp_free_sessions and
3341 silc_client_ftp_session_free_client. Affected file
3342 lib/silcclient/client_ftp.c.
3344 * Added `disabled' field in the SilcChannelEntry in the server
3345 to indicate if the server entry is disabled. Affected file
3346 silcd/idlist.h, silcd/command[_reply].c.

3349 started. Affected file silcd/silcd.c.
3351 * Added silc_server_packet_send_clients to send a packet to
3352 the provided table of client entries. Affected file
3353 silcd/packet_send.[ch].
3355 * Fixed a crash in client resolving in client_prvmsg.c in
3356 client library. Affected file lib/silcclient/client_prvmsg.c.
3358 * Do not actually remove the client directly from ID cache
3359 during SERVER_SIGNOFF, but invalidate it. This way we
3360 preserve the WHOWAS info for the client. Affected file
3361 silcd/server_util.c.
3363 * Fixed SERVER_SIGNOFF notify handling in the server. The
3364 server is now able to process incoming SERVER_SIGNOFF notify
3365 for a server that it doesn't even know about. It will remove
3366 the clients provided in the notify. Affected file
3367 silcd/packet_receive.c.
3369 * Check for partial packet in data queue after every packet that
3370 was found from the queue. Return and wait for more data if
3371 there is partial data in queue. Affected file is
3372 lib/silccore/silcpacket.c.
3374 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
3376 * Added SilcClietFileError enum to indicate error in
3377 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
3378 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
3379 Affected files lib/silcclient/silcapi.h and
3380 lib/silcclient/client_ftp.c.
3382 * Check that newsize in silc_buffer_realloc is larger than
3383 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
3385 * Added better monitor of file transfers. It now monitors
3386 key agreement protocol during the file transfer too. Added
3387 error reporting too. Affected files
3388 irssi/src/silc/core/silc-servers.c,
3389 irssi/src/fe-common/silc/module-formats.[ch].
3391 * Wrote a help file for FILE command.
3393 * Added silc_rng_global_get_byte_fast to get not-so-secure
3394 random data as fast as possible. Random data is read from
3395 /dev/urandom if available and from the SILC RNG if not
3396 available. It is used in padding generation. Affected file
3397 lib/silccrypt/silcrng.[ch].
3399 * All packets in client library are now processed synchronously.
3400 Optimized packet processing a lot. Affected file
3401 lib/silcclient/client.c.
3403 * All server connection packets are processing synchronously
3404 now in server, to optimize packet processing. Affected file
3407 * Include files are installed now only in Toolkit distribution
3408 if make install is given. Affected files: all Makefile.am's.
3410 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3412 * Assure that silc_client_notify_by_server_resolve does not
3413 resolve the client information multiple times. If it cannot
3414 be found by the first it cannot be found at all. Affected
3415 file lib/silcclient/client_notify.c.
3417 * Fixed WHOWAS command reply calling. Affected file
3418 lib/silcclient/command_reply.c.
3420 * Removed all references to silc_idlist_get_client from the
3421 Irssi SILC client since that call is internal call used by
3422 the library. The Irssi SILC client will use now client
3423 retrieval functions found in silcapi.h.
3425 * Fixed a bug in resolving nickname info before sending
3426 private message. It used freed memory. Affected file
3427 irssi/src/silc/core/silc-servers.c.
3429 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3431 * Assure my_channels statistics cannot go negative in server.
3432 Affected files silcd/server.c, silcd/server_util.c.
3434 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3436 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
3438 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

3444 lib/sftp/sftp_fs_memory.c.
3446 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3448 * Added silc_net_localip to return local host's IP address.
3449 Affected file lib/silcutil/silcnet.[ch].
3451 * If key exchange or rekey protocol is active for a connection
3452 parse all packets syncronously since there might be packets
3453 in packet queue that we are not able to process without first
3454 processing packets before them. Affected file silcd/server,
3455 lib/silcclient/client.c.
3457 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
3458 whether library should continue processing the packet.
3459 Affected file lib/silccore/silcpacket.h.
3461 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
3462 SilcSFTPMonitorData to SFTP server to monitor various
3463 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

3470 Added preliminary support for simple client to client one-file
3471 transmission. Affected file lib/silcclient/client_ftp.c,
3472 lib/silccilent/client.[ch].
3474 * Added new local command FILE to the Irssi SILC Client.
3475 It is used to perform the file transfer. It has subcommands
3476 SEND, RECEIVE, SHOW and CLOSE. Affected files
3477 irssi/src/silc/core/client_ops.c,
3478 irssi/src/silc/core/silc-server.[ch].
3480 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3482 * Relay the SILC_PACKET_FTP in the server. Affected files
3483 silcd/server.c and silcd/packet_receive.c.
3485 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3487 * Renamed silc_file_read and silc_file_write to functions

3490 lib/silcutil/silcutil.[ch].
3492 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3494 * Resolve the client info when received private message or
3495 channel message for a client which nickname we don't know.
3496 Affected files lib/silcclient/client_prvmsg.c and
3497 lib/silcclient/client_channel.c.
3499 * Do not crash in /KEY if client is not connected. Affected
3500 file irssi/src/silc/core/silc-channels.c.
3502 * Added SilcClientStatus field to the SilcClientEntry in the
3503 lib/silcclient/idlist.h.
3505 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
3506 is incomplete and is being resolved, it won't be resolved
3509 Make sure also that USERS command reply does not resolve
3510 twice information. Affected file is
3511 lib/silcclient/command_reply.c.
3513 Make sure that silc_client_get_clients_by_list does not
3514 resolve twice same information.
3516 * Check for valid client->id in the silc_server_free_client_data.
3517 Affected file silcd/server.c.
3519 * Fixed /GETKEY nick@server not to crash if the server entry
3520 is not found. Affected file lib/silcclient/command.c.
3522 * Fixed the silc_server_check_cmode_rights to check the
3523 requested modes correctly. Affected file silcd/command.c.
3525 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3527 * Better checks for non-printable chars in nick added.
3528 Affected file silcd/command.c.
3530 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3532 * Call the silc_server_udpate_servers_by_server in the
3533 primary router that comes back online in the backup resuming
3534 protocol. Otherwise it routes packets wrong. Affected file
3535 silcd/server_util.[ch], silcd/server_backup.c.
3537 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3539 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
3540 lib/silcutil/silcbuffmt.[ch].
3542 * Redefined the SILC packet header to include the padding
3543 length. Affected file lib/silccore/silcpacket.[ch].
3545 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
3546 length for maximum padding up to 128 bytes). Affected
3547 file lib/silccore/silcpacket.h.
3549 * Removed all backwards support for old 0.5.x MAC thingies.
3550 The SILC packet header change makes it impossible to be
3551 backwards compatible.
3553 * Send the ENDING packet with timeout in the backup resuming
3554 protocol. This is to assure that all routers has connected
3555 to the primary router. Affected file silcd/server_backup.c.
3557 * Changed the RNG to take the first IV from random data. It
3558 used to take it from zero actually. Changed the RNG also
3559 to use /dev/urandom during session. /dev/random is used
3560 in initialization. Affected file lib/silccrypt/silcrng.[ch].
3562 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3564 * Changed the SILC packet header to have the first two bytes
3565 (the packet length) encrypted. Affected files aroung the
3566 code tree, lib/silccore/silcpacket.[ch]. Removed the
3567 SilcPacketCheckDecrypt callback. It is not needed anymore
3568 since the silc_packet_receive_process will determine now
3569 whether the packet is normal or special.
3571 * Implemented the unidirectional MAC keys. Affected files
3572 lib/silcske/silcske.c, silcd/protocol.c and
3573 lib/silcclient/protocol.c.
3575 * Implemented the packet sequence number to the MAC computation.
3576 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
3577 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
3578 lib/silcclient/protocol.c.
3580 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3582 * Allow backup router to announce servers. All servers
3583 announced by backup router are added to the global list
3584 automatically. Update hte server's socket to our primary
3585 router also when backup router announces a server.
3586 Affected file silcd/packet_receive.c.
3588 * Do not update the client->router in the function
3589 silc_server_udpate_clients_by_server if the client is on
3590 global list. We might fail to find any specific server
3591 for locally connected clients and local cell clients. They
3592 should still use the `from' and not `to' as client->router.
3593 This fixes backup router resuming protocol. Affected file
3594 silcd/server_util.c.
3596 * Decrease channel statistics count only if the channel
3597 deletion worked. Affected files are silcd/server.c and
3598 silcd/server_util.c.
3600 * Added silc_server_update_servers_by_server to update origin
3601 of all server entries. Used during backup router protocol.
3602 Affected files silcd/server_util.[ch], silcd/server.c. and
3603 silcd/backup_router.c.
3605 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
3606 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
3607 silc_hmac_get_hash and silc_hmac_get_name. Affected file
3608 lib/silccrypt/silchmac.c.
3610 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3612 * Assure that router cannot reroute the same channel message
3613 to the sender. Affected file silcd/packet_receive.c.
3615 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3617 * Made better checks that the channel message is not sent
3618 to the router it came from. Affected file is
3619 silcd/packet_send.c. Fixed memory leak too.
3621 * Announce informations for incoming router connection, but
3622 only after checking if it is replaced by backup router.
3623 Affected file silcd/packet_receive.c.
3625 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3627 * Fixed the backup resuming protocol to work in multiple
3628 router environment. Affected file silcd/server_backup.c.
3630 * Route packet only to one router in the function
3631 silc_server_packet_send_to_channel. Affected file is
3632 silcd/packet_send.c.
3634 * Fixed silc_server_send_notify_dest to set the broadcast
3635 flag. Fixed the silc_server_send_notify_topic to actually
3636 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
3637 Affected file silcd/packet_send.c.
3639 * Changed the SFTP Filesystem interface. Changed the
3640 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
3641 the filesystem operation function. The SilcSFTPFilesystem
3642 is now a context that is allocated by all filesystem allocation
3643 functions and it already includes the operations structure
3644 and filesystem specific context. It is given as argument
3645 now to the silc_sftp_server_start. This made the interface
3646 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
3647 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
3649 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3651 * Changed the backup router adding and getting interfaces
3652 in the server. The router that will be replaced by the
3653 specified backup router is now sent as argument. Affected
3654 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
3657 * Added silc_net_addr2bin_ne to return the binary form of
3658 the IP address in network byte order. Affected files
3659 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
3661 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3663 * Check for existing server ID in silc_server_new_server
3664 and in silc_server_connect_to_router_final and remove the
3665 old entry if it exists. Affected file silcd/packet_receive.c,
3668 * Send the channel message always to only one router, either
3669 in upstream or downstream. Affected file is
3670 silcd/packet_send.c.
3672 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3674 * Wrote the definition of the backup resuming protocol to the
3675 protocol specification.
3677 * Removed one redundant channel key generation from normal
3678 server during joining procedure. Removed one redundant
3679 channel key sending from server to router during joining
3680 procedure. Affected file silcd/command.c.
3682 * Made minor bugfixes to the backup router resuming protocol.
3683 Affected file silcd/server_backup.c, server.c.
3685 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3687 * Added --disable-asm configuration option. Affected files
3688 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
3691 * Implemented the backup resuming protocol that is used to
3692 resume the primary router position in the cell after the
3693 primary router comes back online. Affected files
3694 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
3695 and silcd/server_util.[ch].
3697 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3699 * Sleep two (2) seconds after sending QUIT command to server.
3700 Affected file lib/silcclient/command.c.
3702 * Assure that if outgoing data buffer is pending do not force
3703 send any data. Affected file silcd/packet_send.c.
3705 * Assure that if outgoing data buffer is pending do not force
3706 send any data. Affected file lib/silcclient/client.c.
3708 * Implemented the backup router support when the primary router
3709 goes down. The servers and routers can now use the backup
3710 router as new primary router without loosing connectivity.
3712 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3714 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
3715 in the server to indicate disabled entry. All data read
3716 from the connection will be ignored and no data is sent
3717 for entry that is disabled. Affected files are
3718 silcd/idlist.h, silcd/server.c.
3720 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3722 * Created SFTP client and server test programs in the
3723 lib/silcsftp/tests directory.
3725 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
3727 * Implemented memory filesystem (virtual filesystem) for
3728 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
3731 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3733 * Implemented the SFTP (SSH File Transfer Protocol) to the
3734 lib/silcsftp. It includes SFTP client and SFTP server
3737 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3739 * Moved lib/silccore/silcprotocol.[ch] to the
3740 lib/silcutil library.
3742 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
3743 take variable argument list pointer as argument. Affected
3744 file lib/silcutil/silcbuffmt.[ch].
3746 * Added silc_buffer_set function that is used to set data
3747 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
3748 Affected file lib/silcutil/silcbuffer.h.
3750 * Changed various routines in the core library to use the new
3751 silc_buffer_set instead of allocating new buffer only for
3754 * Added 64-bit value formatting and unformatting support to the
3755 silc_buffer_[un]format routines. Affected file is
3756 lib/silcutil/silcbuffmt.[ch].
3758 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
3759 to includes/bitmove.h.
3761 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3763 * Fixed channel user mode saving in client library. Affected
3764 file lib/silcclient/command[_reply].c.
3766 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3768 * Defined the file transfer to the SILC Protocol. Added
3769 new packet type SILC_PACKET_FTP and defined File Transfer
3770 Payload. The mandatory file transfer protocol is SFTP
3771 (SSH File Transfer Protocol). Affected file in addition
3772 of the internet draft is lib/silccore/silcpacket.h.
3774 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
3775 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
3776 is used as part of backup router protocol when the primary
3777 router of the cell is back online and wishes to resume
3778 the position as primary router.
3780 * Redefined the MAC generation keys in the protocol. The
3781 same key is not used anymore in both direction. Both
3782 direction will now use different keys for sending and
3783 receiving. This fixes a potential security flaw. This
3784 change causes incompatibilities in the protocol.
3786 * Redefined also the MAC computation from the packet.
3787 An packet sequence number is now added to the MAC
3788 computation. This prevents possible replay attacks against
3789 the protocol. This change too causes incompatibilities
3792 Added `sequence' field to the SilcPacketContext to hold
3793 the current sequence number for the packet.
3795 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3797 * Added `created' field to the SilcIDListData in the file
3798 silcd/idlist.h to indicate the time when the entry was
3801 * Added `created' field to the SilcChannelEntry too. Affected
3802 file silcd/idlist.h.
3804 * Added `creation_time' aguments to all the announcement functions
3805 in the server. If it is provided then only the entries that
3806 was created after the provided time frame are actually
3807 announced. Affected file silcd/server.[ch].
3809 * The protocol says that the Channel ID's IP address must be
3810 based on the router's IP address. Added check for this in
3811 the silc_server_new_channel when processing incoming New Channel
3812 Payload. Affected file silcd/packet_receive.c.
3814 * Print out the correct version with --version in SILC client.
3815 Affected file irssi/src/silc/core/silc-core.c.
3817 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3819 * Fixed WHOWAS command to check for completnes of the client
3820 entry always, not just when the command is coming from client.
3821 Affected file silcd/command.c.
3823 * Added new function silc_server_packet_queue_purge to purge the
3824 outgoing data queue to the network. After the function returns
3825 it is guaranteed that the outgoing packet queue is empty.
3826 Affected file silcd/packet_send.[ch].
3828 * Purge the outgoing packet queue in the rekey protocol's final
3829 callback to assure that all rekey packets go to the network
3830 before quitting the protocol. Affected file silcd/server.c.
3832 * Added silc_client_packet_queue_parse as similar function as
3833 in server to the client library. The affected file is
3834 lib/silcclient/client.c.
3836 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3838 * Splitted silcd/server.c and created silcd/server_util.[ch]
3839 for utility functions.
3841 * Added new socket flag SILC_SF_DISABLED to indicate that the
3842 connection is open but nothing can be sent to or received from
3843 the connection. Affected file lib/silcutil/silsockconn.[ch].
3844 The checking for disabled socket is checked in the low level
3845 silc_socket_write and silc_socket_read functions.
3847 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3849 * Allow only nicknames and channel names that fits into the
3850 7-bit unsigned char ASCII set. Affected file silcd/command.c.
3852 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3854 * When processing JOIN command reply in server check that if
3855 the channel exists in our global list we'll move it the local
3856 list. Affected file silcd/command_reply.c.
3858 * Fixed the check whether client is joined on the channel already
3859 in JOIN command. Affected file lib/silcclient/command.c.
3861 * Fixed the JOIN command reply to check whether the channel
3862 already exists. Affected file lib/silcclient/command_reply.c.
3864 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3866 * Added silc_ske_status_string to map the SKE error numbers
3867 to readable strings. The affected files are
3868 lib/silcske/silcske[_status].[ch].
3870 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3872 * Do not show the private channels on the WHOIS channel list
3873 as it is not allowed by the protocol. The affected file is
3876 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3878 * Assure that the packet length digged from the actual packet
3879 is something sensible in the silc_packet_decrypt_rest_special
3880 in lib/silccrypt/silcpacket.c.
3882 * Free and NULL the allocated pointer in silc_hmac_alloc if
3883 the HMAC allocation fails. The affected file is
3884 lib/silccrypt/silchmac.c.
3886 * Print the selected security properties to the log files in
3887 the server. Affected file silcd/protocol.c.
3889 * Add SKE's reference counter even if calling the completion
3890 callback manually. Otherwise it goes negative, although it
3891 does not cause any problems. The affected file is
3892 lib/silcske/silcske.c.
3894 * Remove the client entry with short timeout after giving the
3895 KILL command. Affected file lib/silcclient/command.c.
3897 * Fixed to send error reply in WHOIS and IDENTIFY commands in
3898 case all found clients are already disconnected (WHOWAS would
3899 found them) in the server. Affected file silcd/command.c.
3901 * Update the last_receive (time of last data received) to be
3902 updated only when received private or channel message so that
3903 the idle time showed in WHOIS makes more sense.
3905 * Added boolean field `valid' in to the SilcClientEntry in the
3906 client library to indicate whether the entry is valid or not.
3907 This fixes the nickname change bug on channel when changing
3908 the nickname to be same than the old (like nick to Nick) the
3909 nickname formatter doesn't set the new nick anymore to Nick@host.
3910 Affected file lib/silcclient/idlist.[ch].
3912 * Now actually fixed the nickname changing on disconnection.
3913 Added new function silc_change_nick to the Irssi SILC Client.
3914 Affected file irssi/src/silc/core/client_ops.c,
3915 irssi/src/silc/core/silc-nicklist.[ch].
3917 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3919 * Check that the public key exists in the GETKEY command before
3920 trying to encode it. Affected file silcd/command.c.
3922 * Print some notifications on received public keys with GETKEY
3923 command in the Irssi SILC Client. Affected files are
3924 irssi/src/fe-common/silc/module-formats.[ch],
3925 irssi/src/silc/core/client_ops.c.
3927 * Use IDENTIFY command to resolve the server information in the
3928 GETKEY command instead of INFO command. Affected file
3929 lib/silcclient/command.c.
3931 * All command reply functions in the client library now calls
3932 the pending command reply callbacks even if an error has
3933 occurred. The server has done this a long time and now it was
3934 time to move the client library to this as well. Now all
3935 errors can be delivered back to the pending command reply
3936 callbacks if necessary. Affected files are
3937 lib/silcclient/command[_reply].[ch].
3939 * Change the nickname on disconnection back to the username
3940 because in reconnect the server will enforce it to it anyway.
3941 Affected file irssi/src/silc/core/silc-servers.c.
3943 * Fixed a config file parsing bug in the Irssi SILC client.
3944 Affected file irssi/src/silc/core/clientconfig.c.
3946 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3948 * When printing the channel mode on JOIN, verify that the
3949 channel key and channel's HMAC are valid. Affected file
3950 irssi/src/silc/core/client_ops.c.
3952 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3954 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3955 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3956 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3958 * Removed channel key rekey task deleting from the function
3959 silc_server_save_channel_key. Affected file silcd/server.c.
3960 Added explicit timeout task context instead that is used to
3961 delete the task if we are registering a new task before the
3962 new task has elapsed.
3964 * When channel key rekey occurs the client library now saves
3965 the old channel key for a short period of time (10 seconds) and
3966 is able to use it in case some is still sending channel
3967 messages encrypted with the old key after the rekey. Affected
3968 file lib/silcclient/[idlist.h|client_channel.c].
3970 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3972 * Added check to the silc_server_new_id_real to not accept
3973 new ID if it is the sender's own ID. Affected file is
3974 silcd/packet_receive.c.
3976 * Assure that we do not announce ourself or the one we've
3977 sending our announcements when we're router and are announcing
3978 servers to our primary router. Affected file silcd/server.c.
3980 * Fixed silc_server_command_identify_check_client to assemble
3981 correct WHOIS packet. It send corrupted WHOIS packet and
3982 caused problem with router to router connections. Affected
3983 file silcd/command.c.
3985 Fixed also silc_server_command_whois_check the same way
3986 as for the IDENTIFY command.
3988 * Added new SilcIDListStatus to the server in the SilcIDListData
3989 structure. The status now includes the current status of
3990 the entry (like registered, resolved etc.). Affected file
3991 silcd/idlist.[ch]. Defined a bunch of different status types
3992 as well. This replaced the old boolean registered field as well.
3994 Added resolve_cmd_ident field to the SilcClientEntry structure
3995 too so that if the entry is for example being resolved so
3996 another command may attach to the same pending command reply
3997 without requiring to resolve the same entry again. This concept
3998 should optimize the WHOIS and the IDENTIFY resolving under
3999 heavy load by taking away unnecessary resolving for entries
4000 that are being resolved already.
4002 Added support for adding multiple pending commands for one
4003 command idenfier. Affected file silcd/command[_reply].[ch].
4005 * Fixed WHOIS and IDENTIFY save to remove the cache entry
4006 before deleting the data. Otherwise the hash table will have
4007 freed data in comparison functions. Affected file is
4008 silcd/command_reply.c.
4010 * Fixed silc_idlist_replace_client_id to add the new entry to
4011 the cache with NULL nickname. Otherwise there will be invalid
4012 memory as the nickname after the nickname is freed. Affected
4013 file silcd/packet_receive.c.
4015 * Fixed the silc_idlist_get_clients_by_hash. The entries was
4016 saved into wrong slots because the previous number of entries
4017 was not taken into account. Affected file silcd/idlist.c.
4018 Fixed same thing in silc_idlist_get_clients_by_nickname too.
4020 * If we are router and we receive JOIN notify to a channel that
4021 does not have any users then notified client is marked as the
4022 channel founder, as it is it. The affected file is
4023 silcd/packet_receive.c
4025 * Added to the extended hash table API's table_del_*ext functions
4026 the destructor as argument too, so that the caller can decide
4027 which destructor to use or whether to use destructor at all.
4028 Affected file lib/silcutil/silchashtable.[ch].
4030 * Fixed ID Cache purging. It actually deleted the entries from
4031 the hash table after the data was freed. The hash table ended
4032 up comparing freed memory. The affected file is
4033 lib/silccore/silcidcache.c.
4035 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4037 * Fixed Irssi SILC client's KILL command's HELP syntax.
4039 * The USERS command now resolves the detailed user information
4040 if the userinfo field is missing. Affected file is
4041 lib/silcclient/command_reply.c.
4043 * Do not print error in silc_file_read if the read file does
4044 not exist. Just silently return NULL. Affected file is
4045 lib/silcutil/silcutil.c.
4047 * Fixed the silc_log_output to not wine about NULL filename
4048 and to not create some bogus " " filename. Affected file is
4049 lib/silcutil/silclog.c.
4051 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4053 * Fixed various printing bugs on the user interface in the
4054 Irssi SILC Client. Minor changes that were forgotten from
4057 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4059 * Fixed the configure.in.pre and the compilation and distribution
4060 environment to support the new autoconf 2.52. That version is
4061 now required to compile the CVS trunk.
4063 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4065 * Renamed function silc_parse_nickname to silc_parse_userfqdn
4066 to generally parse user@fqdn format strings. Affected file
4067 lib/silcutil/silcutil.c.
4069 * Added nickname_format and nickname_force_format fields to the
4070 SilcClientParams structure. The first one defines the format
4071 for the nicknames that the library will enforce if the receives
4072 multiple same nicknames. The second one is boolean value and
4073 can be used to force the library to always enforce the format
4074 to the nicknames regardles whether there are multiple nicknames
4075 or not. This configurable formatting was employed to flexibly
4076 support accessing multiple nicknames from the user interface.
4077 The userinterface can now set the nicknames to what ever format
4078 they prefer. Affected file lib/silcclient/silcapi.h.
4080 Added function silc_client_nickname_format to the file
4081 lib/silcclient/idlist.c. It performs the nickname formatting.
4083 Added new field `hostname´ to the SilcClientEntry context.
4084 It holds the hostname of the client. Affected file is
4085 lib/silcclient/idlist.h.
4087 * Irssi SILC Client sets the nicknames in nick@hostn format.
4088 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
4089 irssi/src/silc/core/silc-core.c.
4091 The WHOIS printing now also shows both the real nickname and
4092 the formatted nickname so that user knows how to access the
4093 user if there are multiple same nicknames cached. Affected
4094 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
4095 printing formatting too to take the hostname now as a separate
4096 argument. The Affected file is
4097 irssi/src/fe-common/silc/modules-formats.[ch].
4099 * Changed the silc_client_get_clients_local to accept the formatted
4100 nickname as argument. It accepts the real nickname too but the
4101 formatted nickname can be used to find the true entry from
4102 multiple entries. Affected file lib/silcclient/silcapi.h and
4103 lib/silcclient/idlist.c.
4105 * Added nickname_format_parse field to the SilcClientParams.
4106 It is a callback function provided by the application to parse
4107 the nickname out of the formatted nickname string. The library
4108 calls it to get the nickname from the formatted string. Since
4109 the application generally knows better the format of the nickname
4110 string it parses it instead of the library, even though library
4111 encodes the formatted string. If the callback function is not
4112 provided then the library will use the string as is. The
4113 affected file is lib/silcclient/silcapi.h.
4115 * All the nickname strings passed to the client library in
4116 commands are now expected to be formatted nickname strings.
4117 If the command does not support the formatted nickname string
4118 it will assume that the sent string is the actual nickname.
4119 Affected file lib/silcclient/command.c.
4121 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4123 * Added public key authentication support to OPER and SILCOPER
4124 commands in the client library. Affected file is
4125 lib/silcclient/command.c.
4127 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4129 * Changed the get_auth_methdod client operation to be asynchronous.
4130 It can be async if the application resolves the authentication
4131 method from the server during the negotiation. Added new
4132 SilcGetAuthMeth completion callback that the application will
4133 call after resolving the authentication method.
4135 Added function silc_client_request_authentication_method that
4136 the application can use to resolve the authentication method
4137 from the server. Added also SilcConnectionAuthRequest callback
4138 that the library will call after the server has replied. The
4139 application can call this function if it does not know the
4140 current authentication method.
4142 Affected files are lib/silcclient/client.c and
4143 lib/silcclient/silcapi.h.
4145 * The Irssi SILC client now automatically resolves the authentication
4146 method incase any configuration information is not present (and
4147 currently there never is). The affected file is
4148 irssi/src/silc/core/client_ops.c.
4150 * Fixed public key authentication from the client library.
4151 Affected file lib/silcclient/protocol.c. Changed also the
4152 protocol specification about the public key authentication in
4153 the connection authentication protocol. The actual data to be
4154 signed is now computed with a hash function before signing.
4156 * Fixed the public key authentication from the server as well.
4157 Affected file silcd/protocol.c.
4159 * Removed the mlock()'s from the memory allocation routines.
4160 Affected file lib/silcutil/silcmemory.c. The ./configure does
4161 not check anymore for the mlock(). Affected file is
4164 * Fixed USERS command in server to allow the execution of the
4165 command for private and secret channels if the client sending
4166 the command is on the channel. Affected file silcd/command.c.
4168 * Fixed silc_client_get_clients_local to return the clients
4169 count correctly. It could return wrong value. Affected file
4170 lib/silcclient/idlist.c.
4172 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4174 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
4175 types. The assembler optimizations seemed not to like 64-bit
4176 data types. The assmebler optimizations thus are now enabled
4177 also for BSD systems as opposed to only enable them for Linux.
4179 * Do not check for threads at all on BSD systems. Affected
4180 file configure.in.pre.
4182 * Removed -n and -h options from the Irssi SILC Client since
4183 they are not used in silc.
4185 * Fixed the prime generation to assure that the first digit
4186 of the generated random number is not zero since our conversion
4187 routines does not like number strings that starts with zero
4188 digit. If zero digit is seen the random number is regenerated.
4189 This caused some corrupted RSA keys when the zero first digit
4190 was met. Affected file lib/silcmath/silcprimegen.c.
4192 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4194 * Fixed WIN32 configuration in the ./configure script.
4195 Fixed to include xti.h on environments that has it.
4196 Patches by Carsten Ilchmann and andrew.
4198 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4200 * Changed the silc_id_create_client_id to be collision
4201 resistant. It is now assured that there cannot be created
4202 two same client ID's. I suspect that some weird bugs in
4203 the server were actually caused by duplicate Client IDs.
4204 Affected file silcd/serverid.[ch]. A router receiving
4205 new ID now also assures and informs the sending server
4206 if the ID caused collision.
4208 * Changed the silc_id_create_channel_id to also assure that
4209 there are no collisions.
4211 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4213 * Statement about ignoring the Mutual Authentication flag when
4214 performing rekey with PFS was a bit misleading. It is ignored
4215 if it was set in the initial negotiation, it cannot be even
4216 set in the rekey. Fixed in the ke-auth draft. Started the
4217 new versions of the protocol drafts in the doc/.
4219 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4221 * Fixed a bug in silc_client_command_identify_save when saving
4222 new channel information. The channel name was no duplicated
4223 and caused crash on exit. Affected file is
4224 lib/silcclient/command_reply.c.
4226 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4228 * Fixed the getkey command handling in the server. Send just
4229 empty OK reply to the sender if the key could not be fetched
4230 (but everything else was ok, like the key just was not available).
4231 Changed the public key parameter to optional in the protocol
4232 specs so that empty OK reply can be sent. Affected file
4235 Added a message to Irssi SILC client to tell to user if the
4236 server did not return a public key.
4238 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
4240 * Fixed a channel key regeneration bug. It registered new
4241 timeout tasks exponentially until all system resources were
4242 used. Affected file silcd/server.c.
4244 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4246 * Added the SILC Document generator to the scripts/silcdoc.
4247 It can be used to generate the Toolkit Reference Manual out
4248 of the source tree. Internally it will also use the RoboDoc
4249 generator now imported in util/robodoc.
4251 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4253 * Added couple of return's in rekey protocol if error orccurred
4254 during the protocol. The execution must be terminated.
4255 Affected file silcd/protocol.c. Also, terminate the protocol
4256 always with timeout.
4258 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4260 * The client's Client ID was created initally from the wrong
4261 nickname (it could have been in format nick@host) in the
4262 silc_server_new_client. Affected file silcd/packet_receive.c
4264 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4266 * Added some SILC_LOG_ERROR's to various error conditions
4267 if client could not be added to ID cache. Affected files
4268 silcd/packet_receive.c and silcd/server.c.
4270 * When client's sock->user_data is freed, NULL also the
4271 client->router and client->connection pointers. Added check
4272 for these pointers being NULL to various places around the
4273 code. Affected file silcd/server.c.
4275 * Added client->data.registered == TRUE checks to various
4276 places around the code to assure that unregistered client's
4277 are not handled when it is not allowed. Affected file
4280 * Added `bool registered' fields to all
4281 silc_idlist_[server|client]_get_* routines to indicate whether
4282 the fetched client needs to be registered or not. Affected
4283 file silcd/idlist.[ch].
4285 * Add your own entry as registered to the ID cache in the
4286 server. Affected file server.c.
4288 * Fixed a bug in silc_server_new_server. The SilcServer was
4289 set as the new server's context instead of SilcServerEntry.
4290 This naturally caused some weird bugs.
4292 * Added "updated" field the SilcChannelEntry which indicates
4293 the time since the channel entry was last accessed. This
4294 can be used to determine whether it is necessary to
4295 announce the channel after backup resuming protocol.
4296 Affected files silcd/idlist.[ch].
4298 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4300 * Do not delete the channel rekey task when adding it
4301 for in silc_server_create_channel_key.
4303 * Changed the silc_server_create_channel_key to return
4304 TRUE or FALSE to indicate the success of the channel key
4307 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4309 * Fixed MSVC++ project files and added missing files to
4310 Makefiles under win32/.
4312 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4314 * Do not add TCP_NODELAY flag if the operating system
4315 does not have it defined. Affected files are
4316 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
4318 * Fixed buffer overflow from Irssi SILC Client. Affected
4319 file irssi/src/fe-common/core/themes.c.
4321 * Fixed double free in client library in the file
4322 lib/silcclient/client.c when disconnecting from server.
4324 * Applied double free patch from cras to Irssi SILC client.
4325 Affected files irssi/src/core/[modules/expandos].c
4327 * Fixed the disconnection handling to Irssi SILC Client.
4328 The application must call silc_client_close_connection
4329 in ops->connect client operation in case of failure of
4330 the connection. Affected file is
4331 irssi/src/silc/core/client_ops.c.
4333 * Do not set sock->protocol to NULL in the function
4334 silc_client_close_connection after executing the protocol's
4335 final callback since the sock might not be valid anymore.
4336 Affected file lib/silcclient/client.c.
4338 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4340 * Do not enable SILC_THREADS if the linking with libpthread
4341 did not happen. Affected file configure.in.pre.
4343 * Added notion to protocol specification that server must
4344 verify the sent authentication payload with CMODE when
4345 setting the channel founder key. Implemented it to the
4346 server. Affected file silcd/command.c.
4348 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4350 * Added _EXTRA_DIST SILC distribution variable to the
4351 distributions file. It is used to conditionally add extra
4352 files or directories to the specific distribution. Affected
4353 files ./prepare, Makefile.am.pre and distributions.
4355 Removed the `_' from the start of the distribution names.
4358 * Added README.WIN32 for instructions to compile the Toolkit
4361 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4363 * Fixed a double free in disconnection in the server. Affected
4364 file is silcd/server.c.
4366 * Fixed the lib/silcske/groups.c to work now also with GMP
4367 MP library. The string conversion did not work when using
4368 specific base and the base is indicated in the string as well.
4370 * Created win32/ directory which now includes MSVC++ specific
4371 stuff so that toolkit (DLLs) may be compiled with MSVC++.
4372 It will appear only in the toolkit distribution
4374 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4376 * Changed the key material distribution function in case when
4377 the hash output is too short. The data is now concatenated
4378 a bit differently than it used to. Made the change to the
4379 SKE protocol specification.
4381 * Added better GMP detection to configure.in.pre. A patch
4384 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4386 * Fixed a minor bug in SKE that might cause some problem on
4387 some platforms. Affected file lib/silcske/silcske.c.
4389 * Added the cookie checking for initiator in the SKE. It checks
4390 that the responder returns the sent cookie unmodified. The
4391 affected file is lib/silcske/silcske.c. Added new SKE
4392 error type INVALID_COOKIE that can be sent during the
4393 negotiation. Fixed some memory leaks as well.
4395 * Added the "invalid cookie" error message to Irssi SILC client's
4398 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4400 * Added `task_max' field to the SilcClientParams to indicate
4401 the maximum tasks the scheduler can handle. If set to zero,
4402 default values are used. Affected file lib/silcclient/silcapi.h.
4404 * Fixed memory leaks in silc_client_close_connection. Affected
4405 file lib/silcclient/client.c.
4407 * Added silc_client_del_client_entry to client library to free
4408 all memory of given client entry. Affected file is
4409 lib/silcclient/idlist.[ch].
4411 * Added new functions silc_client_del_channel and
4412 silc_client_del_server to delete channel and server entries.
4413 Affected file lib/silcclient/[silcapi.h/idlist.c].
4415 * Removed silc_client_del_client_by_id from silcapi.h.
4417 * Fixed the INFO command to return the server's own info
4418 correctly when querying by Server ID. Affected file is
4421 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4423 * Removed the non-blocking settings in WIN32 code in the
4424 silc_sock_[read/write] and added SleepEx instead. Affected
4425 file lib/silcutil/win32/silcwin32sockconn.c. The availability
4426 of input data is now checked with FIONREAD and ioctlsocket.
4428 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4430 * Call silc_schedule_task_del_by_context in the
4431 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
4432 Affected file lib/silccore/silcprotocol.c.
4434 * Call silc_protocol_cancel for active protocols in the
4435 silc_server_close_connection if the funtion
4436 silc_server_free_sock_user_data has not been called.
4437 Affected file silcd/server.c.
4439 * Generic tasks cannot be deleted using the del_by_fd
4440 task deleting function since generic tasks does not match
4441 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
4443 * Added a notion to SILCOPER help file that the SILCOPER works
4444 only on router server, not on normal server.
4446 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4448 * Added for WIN32 support for the new scheduler as well.
4449 Affected file lib/silcutil/win32/silcwin32schedule.c.
4451 * Fixed the SHA1 implementation to work on various platforms.
4453 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4455 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
4456 API. It is part of the scheduler now. Everything else is
4457 as previously but some functions has changed their names.
4458 Checkout the lib/silcutil/silcschedule.h for the interface.
4459 Updated all applications to use the new interface. Affected
4460 files are lib/silcutil/silcschedule.[ch].
4462 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4464 * Found a bug in the SKE implementation. The HASH value,
4465 specified by the protocol, was not computed correctly. The
4466 public key of the responder was not added to the computation
4467 even though it is mandatory. Affected file lib/silcske/silcske.c.
4468 This unfortunately causes incompatibilities with older
4469 clients and servers.
4471 * Added WIN32 specific network init and uninit functions:
4472 silc_net_win32_init and silc_net_win32_uninit to init and uninit
4473 the Winsock2. Affected file lib/silcutil/silcnet.h and
4474 lib/silcutil/win32/silcwin32net.c.
4476 * Set the socket always to nonblocking mode on WIN32 after
4477 reading data or writing data. Affected file is
4478 lib/silcutil/win32/silcwin32sockconn.c.
4480 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4482 * Fixed various compilation problems under WIN32. Affected
4483 files lib/silcutil/win32/silcwin32thread.c and
4484 lib/silcutil/win32/silcwin32schedule.c.
4486 * Removed all _internal.h #includes from public header
4487 files. Internal headers must never be included from
4490 Removed also the lib/silcske/payload_internal.h file.
4492 * All include files that may be needed (public and some others
4493 included by the public headers) by application developers are
4494 now copied to the ./includes directory. It does not copy any
4495 internal headers. Affected file Makefile.defines.pre and all
4496 Makefile.am's under lib/ and subdirs.
4498 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4500 * Do not change the ~/.silc directory's permissions automatically.
4501 Affected file irssi/src/silc/core/clientutil.c.
4503 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4505 * Do not cancel the protocol in silc_server_close_connection
4506 it might cause recursion. Now cancelled in the function
4507 silc_server_free_sock_user_data. Affected file silcd/server.c.
4509 * Fixed the silc_server_remove_clients_by_server to regenerate
4510 the channel keys correctly finally. Added also new function
4511 silc_server_remove_clients_channels to actually do it.
4512 Affected file silcd/server.c.
4514 * Fixed the silc_server_new_channel to not crash by giving
4515 wrong router to the new channel. Affected file is
4516 silcd/packet_receive.c.
4518 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4520 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
4521 which is given as argument to the silc_client_alloc now.
4522 It can be used to configure the client and set various parameters
4523 that affect the function of the client.
4525 * The USERS command in server did not check whether the channel
4526 is private or secret. Affected file silcd/command.c.
4528 * Added new argument to the USERS command in protocol specification.
4529 The USERS command now can take the channel name as argument
4530 as well. Added support for this in client and server and
4531 updated the protocol specs.
4533 * Completed the GETKEY command in client. It can be now used
4534 to fetch also servers public key not only some clients.
4535 Affected files lib/silcclient/command[_reply].c.
4537 * Added silc_client_get_server to return server entry by the
4538 server name. Affected files lib/silcclient/silcapi.h and
4541 * Redefined the IDENTIFY command in protocol specification to be
4542 more generic. It now can be used to query information about
4543 any entity in the SILC Network, including clients, servers and
4544 channels. The query may be based either the entity's name
4545 or the ID. Added support for this in both client and server.
4547 Affected files silcd/command.c and lib/silcclient/command.c
4548 and command_reply.c.
4550 * Optimized the WHOIS and WHOWAS commands in the server. Removed
4551 the _from_client and _from_server functions. Affected file
4554 * Added silc_client_get_channel_by_id_resolve to the file
4555 lib/silcclient/silcapi.h to resolve channel information by
4556 its ID. Added also silc_client_get_channel_by_id that
4557 does not resolve it from the server.
4559 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4561 * Added SilcServerEntry context into the client library
4562 to represent one server. The INFO command now allocates
4563 these to save the resolved server info. For now on the
4564 client library will also keep information about servers,
4565 connected and resolved with INFO.
4567 The INFO command now allocates the SilcServerEntry context
4568 and saves the server info there. The COMMAND_REPLY in
4569 the INFO now returns the parameters to application in
4570 same order as defined in the protocol specification.
4572 The entries are cached in the client->server_cache.
4574 * The INFO command is now issued after received the Client ID
4575 from the server. Affected file lib/silcclient/client.c.
4577 * The CMODE_CHANGE notify may now return also an SilcServerEntry
4578 to the application as the mode changer might be server.
4579 It is guaranteed that NULL is not returned anymore to the
4580 application. Affected file lib/silcclient/client_notify.c.
4582 The ID Type is now also passed to the application so that
4583 it can check whether the returned entry is SilcClientEntry
4586 Added new function silc_client_get_server_by_id to return
4587 the server entry by ID. Affected files are the
4588 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
4590 * Do not create the channel in the Irssi SILC Client when issuing
4591 the JOIN command but when received the sucessful JOIN command
4592 reply. Otherwise the channel might get created even though we
4593 could not join it. The Affected file is
4594 irssi/src/silc/core/[silc-channels.c/client_ops.c].
4596 * Fixed a channel joining bug in router. The router must also
4597 check the channel modes, invite and ban lists etc. when serving
4598 the JOIN command sent by normal server. Affected file is
4599 silcd/command.c. The router now resolves the client's
4600 information from the server who sent the JOIN command if it
4601 does not know it, and processes the JOIN command only after
4604 * Changed the SilcCommandCb to take new argument; void *context2.
4605 Affected file lib/silccore/silccommand.h
4607 The second argument in the command callbacks in the server now
4608 includes the SilcServerCommandReplyContext if the command was
4609 called as pending command callback from the command reply.
4610 Otherwise it is NULL. When called as pending the status of the
4611 command reply will be checked and if it was erronous the
4612 error will be sent to the original sender of the command.
4613 This way the client always receives the error messages even
4614 though the server was actually the one who received the error
4615 when it resent the command to router, for example. Affected
4616 files silcd/command[_reply].[ch].
4618 * Fixed sending WHOWAS command's error message to client if
4619 the requested client could not be found. It was missing.
4622 * Changed the CMODE and CUMODE commands reply arguments in the
4623 protocol specification. The Channel ID is now sent in both
4624 of the commands to identify the channel. Implemented this
4625 new feature to the client and server. Affected files
4626 lib/silcclient/command_reply.c and silcd/command.c.
4628 * Made better checks for invite and ban lists in the JOIN
4629 command in server. Affected file silcd/command.c.
4631 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4633 * The server now performs the incoming host IP/DNS lookup
4634 using the silc_socket_host_lookup and thus does not block
4635 the server anymore. Affected file silcd/server.c.
4637 * Completed the multi-thread support for SILC Scheduler in
4638 the lib/silcutil/silcschedule.c.
4640 * Fixed the configure.in.pre to detect the pthread correctly
4643 * Fixed a deadlock in silc_task_queue_wakeup in the file
4644 lib/silcutil/silctask.c.
4646 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4648 * Added new function silc_schedule_wakeup that is used in
4649 multi-threaded environment to wakeup the main thread's
4650 schduler. It needs to be used when a thread adds a new task
4651 or removes a task from task queues. After waking up, the
4652 scheduler will detect the task queue changes. If threads
4653 support is not compiled in this function has no effect.
4654 Implemented the wakeup mechanism to both Unix and WIN32
4655 systems. Affected files are lib/silcutil/silcschedule.[ch],
4656 lib/silcutil/unix/silcunixschedule.c and the
4657 lib/silcutil/win32/silcwin32schedule.c.
4659 * Added new function silc_task_queue_wakeup to wakeup the
4660 scheduler by the specified task queue. Affected file
4661 lib/silcutil/silctask.[ch].
4663 * The silc_socket_host_lookup_start now wakes up the scheduler
4664 after adding the timeout task. Affected file is
4665 lib/silcutil/silcsockconn.c.
4667 * The silc_socket_host_lookup is synchronous now if the threads
4668 support is not compiled in. However, the callback is still
4669 called asyncronously through the scheduler, anyway. Affected
4670 file lib/silcutil/silcsockconn.c.
4672 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4674 * Added new function silc_socket_host_lookup to perform
4675 asynchronous IP and FQDN lookups for the socket connection.
4676 Affected files lib/silcutil/silcsockconn.[ch].
4678 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4680 * Added SILC_MUTEX_DEFINE to define the mutex on environments
4681 that may or may not compile the mutex support in.
4683 Changed the silc_mutex_alloc interface. It allocates the
4684 mutex now to the sent pointer and returns TRUE or FALSE.
4686 Affected file lib/silcutil/silcmutex.h.
4688 * Wrote the SILC Task Queue interface to support multi-threads.
4689 Affected file lib/silcutil/silctask.[ch].
4691 * Wrote the SILC Scheduler to support multi-threads. Affected
4692 file lib/silcutil/silcschedule.c.
4694 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4696 * Implemented the SILC Mutex API and SILC Thread API for WIN32
4697 in lib/silcutil/win32/.
4699 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4701 * Defined SILC Mutex API and SILC Thread API and implemented
4702 them for Unix. Affected files are
4703 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
4704 lib/silcutil/unix/silcunixmutex.c and
4705 lib/silcutil/unix/silcunixthread.c.
4707 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4709 * Fixed the silc_server_remove_clients_by_server's channel
4710 key re-generation. The hash table handling was incorrect
4711 and would not work with many channels. Affected file is
4714 * Fixed some memory leaks around the server code.
4716 * Rewrote the silc_server_get_users_on_channel to support IPv6
4717 based Client ID's. Affected file silcd/server.c.
4719 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
4720 specification. However, a separate document must be written
4721 to define the detailed signing procedure and the payload
4722 associated with the flag. Defined the flag to the
4723 lib/silccore/silcchannel.h as well.
4725 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4727 * Changed the dynamic tables to static size tables in the
4728 lib/silccrypt/silchmac.c.
4730 * Removed GCC dependencies from the code. A patch by cras.
4732 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4734 * Do not show the error "Error receiving packet bla bla"
4735 in server if it really was not an error (-2 means that reading
4736 is pending). Affected file silcd/server.c.
4738 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4740 * Fixed a possible crash in silc_server_remove_clients_by_server
4741 in silcd/server.c. Fixed there also some memory leaks.
4743 * Fixed the silc_idlist_replace_client_id. It could replace
4744 wrong key in the hash table. Affected file silcd/idlist.c.
4746 * Do not check whether there are global users on the channel
4747 if the channel->global_users is FALSE. Affected functions
4748 silc_server_remove_from_one_channel and
4749 silc_server_remove_from_channels in silcd/server.c. Also,
4750 do not check if the removed client is local as we can be
4751 sure that global client was not removed from the channel
4752 and checking for global users is not needed.
4754 * The silc_server_remove_clients_by_server now re-generates
4755 the channel keys correctly for those channels that had
4756 clients removed from them. Affected file silcd/server.c.
4758 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4760 * Found the reason of random crashes in the server. We weren't
4761 ignoring the SIGPIPE signal (which can be sent in write())
4762 and it crashed the server. Affected file silcd/silcd.c.
4764 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4766 * Assure that sock->user_data is not NULL in the function
4767 silc_server_packet_send in silcd/packet_send.c.
4769 * Disconnect the remote connection if it could not be added
4770 to any ID lists in the server. The affected file is
4773 * Check in silc_server_packet_send[_real/dest] that the
4774 socket is not disconnecting and ignore the data if it is.
4775 Affected file silcd/packet_send.c.
4777 * Define inline to __inline on native WIN32 compilation.
4778 Affected file includes/silcwin32.h.
4780 * Added some explicit type casts for inline code since MSVC
4781 require them. Affected files lib/silcutil/silcbuffer.h,
4782 lib/trq/silcdlist.h and lib/trq/silclist.h.
4784 * Print warning in log files from now on if the packet
4785 decryption fails. Affected file silcd/server.c.
4787 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4789 * Changed the `say' client operation's interface to accept
4790 new `type' argument to indicate the type of the message sent
4791 by the library. The application may filter the library's
4792 messages according the type. The affected file is the
4793 lib/silcclient/silcapi.h.
4795 * Added two new functions to lib/silcclient/silcapi.h:
4796 silc_client_del_client and silc_client_del_client_by_id.
4797 Affected file lib/silcclient/idlist.c.
4799 * Moved the clientincludes.h from includes/ to silc/ and
4800 serverincludes.h from includes/ to silcd/.
4802 * The modes for the CMODE and CUMODE are now passed as
4803 uint32 for application with COMMAND_REPLY. The affected
4804 file is lib/silcclient/command_reply.c.
4806 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4808 * /WHOIS without arguments shows client's own information.
4809 Affected file lib/silcclient/command.c.
4811 * Changed PING to not accept any arguments. The specs
4812 says that client can ping only the connected server so
4813 requiring an argument is not needed. Affected file is
4814 lib/silcclient/command.c.
4816 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4818 * Fixed a fatal bug in private message sending and reception
4819 encryption and decryption when using private message keys.
4820 The implementation was incorrect and did not follow the
4821 specification. It causd that some of the message were
4822 lost since it did not use the sending and receiving keys
4823 as the protocol suggests. This has been fixed and will cause
4824 incompatibilities with older clients when sending private
4825 message encrypted with private message keys. Affected files
4826 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
4827 and various other in Irssi SILC Client.
4829 Added `responder' boolean argument to the functions
4830 silc_client_add_private_message_key[_ske] to indicate when
4831 the key is added as responder or initiator of the key
4834 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4836 * Removed the silc_ske_check_version function and created
4837 a SilcSKECheckVersion callback. Added also a function
4838 silc_ske_set_callbacks that is now used to set all SKE
4839 callbacks. The callback functions are not given to
4840 the SKE functions anymore, but this function is used to
4843 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
4845 * Added `silc_version' argument to the silc_client_alloc
4846 to define the version of the application for the library.
4847 The library will use the version string to compare it
4848 against the remote host's (usually a server) version
4849 string. Affected file lib/silcclient/silcapi.h
4851 * Added the KE protocol context to Key Agreement context
4852 in client library so that we can abort the SKE if it
4853 is in process when we get timeout. Affected file is
4854 lib/silcclient/client_keyagr.c.
4856 * Do not resolve the client ID forever if it returns in the
4857 first time that such client does not exist. This was done
4858 for example with private message. Affected file is
4859 lib/silcclient/client_prvmsg.c.
4861 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4863 * Do not add regex.h for WIN32. The affected file
4864 includes/silcincludes.h.
4866 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
4867 not work yet 100%. It generates the DLL's automatically
4868 when compiling with --with-win32 under cygwin.
4870 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4872 * lib/contrib/regex.c is not compiled on WIN32.
4874 * Added silc_net_get_socket_opt function to the
4875 lib/silcutil/silcnet.h.
4877 * Added includes/silcwin32.h for WIN32 specific includes
4880 * Do not use ptime structure or any of the posix process
4881 functions on WIN32 in lib/silccrypt/silrng.c.
4883 * Added silc_gettimeofday to provide generic function
4884 for struct timeval on all platforms. Added the function
4885 to lib/silcutil/silcutil.h.
4887 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4889 * Moved the lib/silccore/silcsockconn.[ch] to the utility
4890 library as they clearly belong there. As a plus side we
4891 can make the actual socket connection routines platform
4894 Added also new generic function silc_socket_read and
4895 silc_socket_write (that used to be silc_packet_[read/write].
4896 The implementation of these are platform specific.
4898 * Added WIN32 specific routines of silc_socket_[read/write]
4899 to lib/silcutil/win32/silcwin32sockconn.c.
4901 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4903 * Added preliminary support for native WIN32 compilation under
4904 cygwin (using the -mno-cygwin option for GCC) to the
4905 ./configure.in.pre. The --with-win32 now prepares the
4906 compilation for native WIN32.
4908 * Rewrote the SILC Scheduler interface in the file
4909 lib/silcutil/silcschedule.h. The scheduler is now context
4910 based and does not have anymore any global static scheduler.
4911 Moved the Unix scheduler to the lib/silcutil/unix/ directory
4912 and created lib/silcutil/win32 directory for WIN32 based
4915 * Added Unix specific network routines to the
4916 lib/silcutil/unix/silcunixnet.c and the old
4917 lib/silcutil/silcnet.c includes now only generic routines.
4919 Added WIN32 specific network routines to the
4920 lib/silcutil/win32/silcwin32net.c.
4922 * Added Unix specific utility functions from the
4923 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
4925 * Added WIN32 SILC Scheduler to the file
4926 lib/silcutil/win32/silcwin32schedule.c. The code is of course
4929 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
4931 * Do not handle JOIN notify in the server if the target client
4932 is not registered (idata->registered == FALSE). The affected
4933 file is silcd/packet_receive.c.
4935 * Update the nickrec->founder in event_cumode in the Irssi SILC
4936 client. Affected file irssi/src/silc/core/silc-channels.c.
4938 * Fixed the CUMODE_CHANGE notify handling in the server when
4939 server and router are announcing their clients on channels.
4940 Now the mode changes are saved and notified correctly. The
4941 affected file is /silcd/packet_receive.c.
4943 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
4944 They really did not replace the cache entry in the ID Cache.
4945 Now they do that. Affected file silcd/idlist.c.
4947 * Fixed the KICK notify handling in the Irssi SILC client to
4948 update the channel records so that the kicked client does not
4949 appear to be on the channel. The affected file is
4950 irssi/src/silc/core/silc-channels.c.
4952 * Always update the conn->current_channel when executing command
4953 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4955 * Fixed the KILL notify handling in Irssi SILC client to remove
4956 the killed client on all channels.
4958 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4960 * Fixed the silc_parse_command_line to remove extra spaces
4961 from the start and end of the arguments. Affected file is
4962 lib/silcutil/silcutil.c.
4964 * Cancel and free any active protocol in the function
4965 silc_server_close_connection. Affected file silcd/server.c.
4967 * Cancel and free any active protocol in the function
4968 silc_client_close_connction. Affected file is
4969 lib/silcclient/client.c.
4971 * Do not execute the KILL command for clients that are in
4972 history (ie. they are not in the network). Affected file is
4975 * Fixed KILL notify handling, client does not crash anymore.
4976 Affected file irssi/src/silc/core/silc-channels.c.
4978 * Reduced the default packet buffer size from 2048 to 1024 in
4979 lib/silccore/silcpacket.c.
4981 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4982 counter to the SKE context that is incresed when the SKE library
4983 performs async operation outside the library. If the outside
4984 process frees the SKE context and FREED status will be set
4985 and the library will detect after the sync operation that the
4986 libary is freed. The affected files are
4987 lib/silcske/silcske[_status].[ch].
4989 * Resolve the client entry information in the function
4990 silc_client_channel_message to assure that NULL pointer is not
4991 passed as client entry to the application. */
4993 * Fixed the task timeout calculation to assure that there is
4994 never negative timeouts. The affected file is
4995 lib/silcutil/silcschedule.c.
4997 * Fixed the channel user mode notification sending in server.
4998 It was sent point-to-point to the router (or to server by router)
4999 but it needs to be destined to a channel. The routines now
5000 supports sending the channel user mode notifys to the channels
5001 when announcing clients and channels. Affected files are
5002 silcd/server.c and silcd/packet_receive.c.
5004 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
5005 It did not actually replace the old channel entry in the cache.
5006 Affected file lib/silcclient/client_notify.c.
5008 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5010 * Fixed a possible crash in silc_packet_send_prepare. It now
5011 assures always that there is enough space in the buffer and
5012 at the tail area of the buffer (for MAC).
5014 Fixed the inbound buffer reallocation in silc_packet_read.
5015 It was old code and did not handle the reallocation correctly.
5018 The affected file is lib/silccore/silcpacket.c.
5020 * Fixed buffer overflow in silc_parse_nickname in the file
5021 lib/silcutil/silcutil.c.
5023 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5025 * make install generates new server keys only if there is not
5028 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
5031 Added check that if the NOREPLY is set then we will not send
5032 the away message. This avoids infinite loop of away messages
5033 if both clients are away. The affected file is
5034 lib/silcclient/client_prvmsg.c.
5036 * Fixed client crash if /NICK was given without arguments.
5037 Affected file lib/silcclient/command.c.
5039 * Server does not send the invite list in INVITE command back
5040 to the client if the list was not altered. Added this notion
5041 to the protocol spec as well. Affected file silcd/command.c.
5043 Fixed possible crash in INVITE command by checking the
5044 value of silc_server_get_client_route command.
5046 * Fixed the INVITE notify type handling. The arguments are now
5047 taken in correct order and client does not crash. The affected
5048 file is irssi/src/silc/core/silc-channels.c.
5050 Removed the "Inviting xxx to channel" message from the
5051 client library away and let the application handle it.
5052 Affected file lib/silcclient/command.c. Added that message
5053 to Irssi SILC client's message formats.
5055 * Fixed CMODE command crash in client. It now checks the
5056 amount of arguments correctly and does not crash. The affected
5057 file is lib/silcclient/command.c.
5059 * Do not create new channel automatically in silc_channels_join
5060 but check whether the channel by that name already exists.
5061 Affected file irssi/silc/core/silc-channels.c.
5063 * Do not send the SERVER_SIGNOFF to router if the disconnected
5064 entity was the router. Affected file silcd/server.c.
5066 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
5067 SILC client as it was missing from there.
5069 Added the handling of the KICK notify to the Irssi SILC client
5070 as it was missing. Added "you have been kicked" message to
5071 Irssi SILC client's message modules formats.
5073 Added the handing of the KILL notify to the Irssi SILC client
5074 as it was missing. Added the kill message module formats
5077 The affected file is irssi/src/silc/core/silc-channels.c.
5079 * The router did not save the channel mode the server announced.
5080 Affected file silcd/packet_receive.c.
5082 * Fixed a possible crash in INFO command in server. If the
5083 server did not provide the server info it crashed. Affected
5084 file silcd/command.c.
5086 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5088 * Fixed the GETKEY command in the server to check also the
5089 global list. Otherwise the GETKEY would not work correctly
5090 in normal SILC server. Affected file silcd/command.c.
5092 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5094 * Fixed GETKEY crash, it crashed if the command did not succseed.
5096 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5098 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
5099 is now real and not just an macro interface to GMP.
5101 Removed the entire GMP from the source tree and imported new
5102 NSS MPI library instead. Reason for removing GMP is that it is
5103 extremely large and compiles extremely slow. The NSS MPI
5104 is only a few files and compiles in less than 10 seconds.
5105 The speed is also about the same as GMP. The MPI is imported
5106 to lib/silcmath/mpi.
5108 If the system has GMP installed we will still use the GMP.
5109 If it is not then the NSS MPI will be compiled.
5111 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5113 * Merged a long nickname (127 characters long) crash bugfix from
5114 Irssi CVS tree. Affected file irssi/src/core/misc.c.
5116 * Merged a freed memory reference bugfix from Irssi CVS tree.
5117 Affected file irssi/src/core/commands.c.
5119 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5121 * Added the server's public key sving and verification to the
5122 server when performing the SKE. This was missing and the
5123 remote server's (or router's) public key was accepted without
5124 checking whether we have it previously or trust it at all.
5125 Affected file silcd/protocol.c.
5127 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5129 * Check in the silc_server_timeout_remote if protocol is active
5130 and make sure that the protocol's final callback is called so
5131 that all memory if freed. Affected file silcd/server.c.
5133 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5135 * silc_server_whois_send_reply crashed the server if the nickname
5136 was 127 characters long. Affected file silcd/command.c.
5138 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5140 * Added sanity check to the silc_server_new_client. If the hostname
5141 is provided inside username then check that the provided hostname
5142 really is the same as the resolved one. If the hostname was not
5143 resolved then check it from the public key. Affected file is
5144 silcd/packet_receive.c.
5146 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
5147 if the server disconnected us and the connection is not valid
5148 anymore. Affected file irssi/src/silc/core/silc-channels.c.
5150 * Moved the silc_client_[chmode|chumode|chumode_char] away from
5151 the library to the lib/silcutil/silcutil.[ch].
5153 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5155 * Close log file after open. Affected file
5156 lib/silcutil/silclog.c.
5158 * Check whether sock == NULL in silc_client_send_packet and return
5159 if it is. Affected file lib/silcclient/silcclient.c.
5161 * Check rec->entry == NULL in the Irssi SILC Client before
5162 sending the channel message. Affecte file is
5163 irssi/src/silc/core/silc-servers.c.
5165 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5167 * Merged a splitted window bugfix from Irssi CVS tree. The
5168 affected file is irssi/src/fe-text/textbuffer-view.c.
5170 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
5171 It did not print nickname.
5173 * Improved the distributions system a bit.
5175 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5177 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
5178 irssi/src/fe-text/gui-window.c.
5180 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
5181 to in-active server. The affected file is
5182 irssi/src/silc/core/client_ops.c.
5184 * Resolve the client in USERS command reply if the entry does
5185 not have username resolved. The affected file is
5186 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
5187 command to WHOIS command to really resolve stuff. The USERS
5188 is not used any more in any critical section so WHOIS can
5189 be used even though it might be slower than IDENTIFY.
5191 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
5194 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5196 * Changed the protocol API a bit more consistent in the
5197 lib/silccore/silcprotocol.[ch].
5199 * Changed the following headers to ROBODoc format:
5201 lib/silccore/silcpayload.h
5202 lib/silccore/silcprotocol.h
5203 lib/silccore/silcsockconn.h
5205 All core library headers are now formatted.
5207 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5209 * Fixed a bug in Irssi SILC client; do not show that you are
5210 server/router operator if you really are not. Affected file is
5211 irssi/src/silc/core/client_ops.c.
5213 * Renamed silc_command_free_payload to silc_command_payload_free.
5214 Affected file lib/silccore/silccommand.h
5216 * Added silcmath.h to include the prototoypes of various routines
5217 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
5220 * Changed the following headers to ROBODoc format:
5222 lib/silccore/silcchannel.h
5223 lib/silccore/silccommand.h
5224 lib/silccore/silcid.h
5225 lib/silccore/silcidcache.h
5226 lib/silccore/silcmode.h
5227 lib/silccore/silcnotify.h
5228 lib/silccore/silcpacket.h
5229 lib/silcmath/silcmath.h
5231 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5233 * Added checking to the server code not to start the server if
5234 ciphers and stuff are not configured properly. Affected files
5235 silcd/serverconfig.[h] and silcd/server.c.
5237 * Changed the layout of the header files of the public interfaces
5238 in the SILC libraries. The new layout supports ROBODoc
5239 documentation tool (and some others) so that it is easy to create
5240 a library reference manual. All the other headers and source
5241 code must still follow the CodingStyle document. Also source
5242 code must not include these ROBODoc stuffs, only the headers.
5243 Furthermore, all public interface headers must now be named
5244 by using `silc' prefix, example: silcapi.h, silccipher.h.
5245 Some files were renamed due to this. All the other headers
5246 must not be used as public interfaces. I will update the
5247 CodingStyle document later. Changed following headers, so far:
5249 lib/silcclient/silcapi.h
5250 lib/silccore/silcauth.h
5251 lib/silccore/silcprivate.h
5252 lib/silccrypt/silcdh.h
5254 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5258 * Removed silc_client_packet_send_flush from the client library
5259 as it is not needed. Affected file lib/silcclient/client.[ch].
5261 * Added printing of message of unresolved authentication method
5262 to the Irssi SILC client. Added it to the module formats.
5263 Removed the same message from the client library.
5265 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5267 * Added new distribution feature, DISTLABEL. Every distribution
5268 can define own preprocessor label that can be used in the
5269 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
5270 file distributions, acconfig.h.pre and prepare.
5272 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5274 * Added Makefile.defines_int to include the actual definitions
5275 for Makefile.defines.in. Tested the new distribution system,
5276 created distributions and tested installation.
5278 * Added AWAY message printing to the Irssi SILC client. Added
5279 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
5281 * Added SCONNECT command to call the SILC's CONNECT command.
5282 Cannot use CONNECT directly since Irssi uses that internally.
5283 Affected file irssi/src/silc/core/silc-servers.c.
5285 Added ACTION local command. It is same as ME command but takes
5286 the channel as mandatory argument.
5288 Rewrote some of the Irssi's help files to suite for SILC
5291 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5293 * Added Makefile.defines[.in] that should for now on be included
5294 in all Makefile.am file in the source tree. That file includes
5295 all common compilation definitions for SILC source tree.
5297 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5299 * Minor changes to the ./prepare script to change the package
5300 name according the distribution name to the configure.in.
5302 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5304 * Created new distribution system. Added file `distributions'
5305 that defines all the distributions that can be created out of
5306 the SILC source tree. The ./prepare script now reads that
5307 file to determine how to prepare the distributions. The
5308 first argument to the ./prepare is the name of the distribution
5309 and second is the version of the distribution. If given
5310 without arguments it creates the default (toolkit) distribution
5311 with the default version (defined in ./prepare).
5313 All Makefile.am files that are subject to the distributions
5314 are now named as Makefile.am.pre. These are ./Makefile.am
5315 and lib/Makefile.am. Others may be changed later.
5317 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5319 * Added invite list, ban list, some key management and connection
5320 error message printing to module formats in the Irssi SILC client.
5322 * Added new silc_client_set_away_message to set the away message
5323 that is back to the person who sent private message. The
5324 affected file lib/silcclient/silcapi.h and the
5325 lib/silcclient/client_prvmsg.c.
5327 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5329 * Fixed the private message sending in the Irssi SILC client,
5330 added local command KEY to the Irssi SILC client.
5332 Added key management and key agreement message formats to the
5333 irssi/src/fe-common/silc/module-formats.[ch].
5335 Added USERS (alias WHO) printing, server/router operator
5336 indication and LIST command printing to the module formats.
5338 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5340 * Fixed channel joining notify handling, cumode notify handling
5341 from Irssi SILC client.
5343 * Added SILC specific module-formats to the Irssi SILC client so
5344 that SILC specific message hilighting, colors etc is possible.
5345 Affected file irssi/src/fe-common/silc/module-formats.[ch].
5347 Added channel mode, channel user mode, actions, notices,
5348 whois and whowas printing to the the module-formats.c.
5350 * Fixed a bug in channel deletion in the server. The channel
5351 is not left to the cache even if the channel founder auth mode
5352 is set when there are no users anymore on the channel. Affected
5353 file silcd/server.c.
5355 * The silc_net_localhost now resolves the entire hostname including
5356 the domain name. Affected file lib/silcutil/silcnet.c.
5358 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5360 * Changed the ask_passphrase client operation to be ascynchronous.
5361 It has now a completion callback and a context that the
5362 application must call after it has got the passphrase from
5363 the user. Affected files lib/silcclient/silcapi.h,
5364 lib/silcclient/protocol.c, lib/silcclient/command.c and
5367 Added SilcAskPassphrase callback that the application calls
5368 to deliver the passphrase to the library.
5370 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
5371 The public key verification and especially a certificate
5372 verification is asynchronous procedure.
5374 Added new SILC_SKE_STATUS_PENDING status to indicate the
5375 request is pending and a callback will be called to finalize
5378 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
5379 indicate that remote end did not send its public key (or
5380 certificate), even though we require it. Added check for this
5381 condition in the SKE. This was a security bug, now fixed.
5383 Defined new SilcSKEVerifyCbCompletion callback that is called
5384 when the verification process is completed.
5386 The affected files lib/silcske/silcske_status.h and
5387 lib/silcske/silcske.[ch].
5389 * Changed the verify_public_key client operation to be async
5390 as well. Defined SilcVerifyPublicKey callback that is used to
5391 indicate the success of the public key verification process.
5393 Changed the server and client to use the new async client
5396 * Changed the Irssi SILC client's internal scheduler to be called
5397 twice as many times as it used to be. As a result the client
5398 should be a bit faster now. Affected file is
5399 irssi/src/silc/core/silc-core.c.
5401 * Added support to Irssi SILC client of asynchronous public key
5402 verification and passphrase inquiry. Affected file is
5403 irssi/src/silc/core/silc-core.c.
5405 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Do not say "You have left channel %s" in client library.
5408 Moved it to the application. Affected files are
5409 lib/silcclient/command.c and silc/client_ops.c.
5411 * Fixed silc_client_get_clients. Command context was not
5412 duplicated and was freed memory in the callback. Affected
5413 file lib/silcclient/idlist.c.
5415 * Do not say "you are now talking..." on JOIN command in the
5416 client library. The appliation must handle it.
5418 * Do not say ".. changed topic to" in command reply in the
5419 client libary. The application must handle it.
5421 * Fixed TOPIC command sending in the client library.
5423 * Fixed a memory leak in silc_client_command_free in the file
5424 lib/silcclient/command.c.
5426 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5428 * Imported a modified version of Irssi client to the source tree.
5429 The Irssi will be used to create a new client called
5430 Irssi SILC. Imported to irssi/.
5432 Added silc_core_init_finish function to the Irssi. Affected
5433 file irssi/configure.in.
5435 A lot changes in the Makefile.ams around the irssi tree.
5437 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5439 * Do not rehash if the new size is same as the old size of the
5440 hash table, in the silc_hash_table_rehash*. The affected file
5441 lib/silcutil/silchashtable.c.
5443 * Replaced hash_table_del_by_context calls from the server
5444 (when channel->user_list and client->channels) to the
5445 hash_table_del as it is sufficient and faster.
5447 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5449 * Added silc_hash_table_list, silc_hash_table_get and the
5450 SilcHashTableList structure to provide an alternative way to
5451 traverse the hash table. The affected files are
5452 lib/silcutil/silchashtable.[ch].
5454 * Changed the server's idlist routines to use the hash table
5455 routines to optimize the code.
5457 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5459 * Replaced the client entry's `channel' list and channel entry's
5460 `user_list' list to hash tables for optimized lookup. Changed
5461 the code to use the hash table interface around the code.
5462 Affected file lib/silcd/idlist.[ch].
5464 * Added `auto_rehash' boolean argument to the function
5465 silc_hash_table_alloc to indicate whether the hash table should
5466 auto-rehash when it thinks is appropriate time. It will
5467 increase the hash table size if the there is twice as much
5468 entries in the table than the size of the table, and will
5469 decrease the size if there are twice as less entries than
5470 the size of the table.
5472 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5474 * Fixed silc_xxx_get_supported to not crash at some circumstances.
5476 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5478 * silc_idcache_purge_by_context deletes the entry now by context
5479 as it is supposed to do. Affected file lib/silccore/idcache.c.
5481 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
5482 client is not anymore valid (WHOWAS givens the info) and not
5483 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
5485 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5487 * Removed the `data' and `data_len' arguments from the ID Cache
5488 interfaces and added `name' argument. ID Cache does not handle
5489 anymore the binary data only a names associated with given ID.
5491 * When hashing a Client ID with silc_hash_id the entire ID is
5492 not hashed anymore, instead only the hash of the Client ID is
5493 hashed. This way we can access the Client ID from the cache
5494 with Client ID but with the hash of the ID (which is a hash of
5495 the nickname) as well without any difference in performance.
5497 Added also silc_idcache_find_by_id_one_ext to do one on one
5498 searching when we have the actual ID. Added also function
5499 silc_hash_client_id_compare. The affected files are
5500 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
5502 * When hashing the name associated with a ID it is always done
5503 in lowercase. This way we can access the cache without worrying
5504 about case-sensitivity, even though, for example nicknames are
5507 * Fixed a bug in server with channel message sending. It put
5508 wrong ID type as destination ID. The affected file
5509 silcd/packet_send.c.
5511 * silc_idcache_del_by_context now deletes from all hash tables
5512 by context. Affected file lib/silccore/idcache.c.
5514 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5516 * Changed the client library to use the new ID Cache interface.
5517 Changes around the source tree.
5519 * Added silc_hash_table_rehash_ext to rehash with specific
5520 hash function. Affected file lib/silcutil/silchashtable.[ch].
5522 * Added silc_hash_string_compare to compare two strings in the
5523 hash table. Affected file lib/silcutil/silcutil.[ch].
5525 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5527 * Added new function silc_idcache_del_by_context into the
5528 lib/silccore/idcache.[ch].
5530 * Changed the server's ID list routines to use the new ID Cache
5531 interface. Changes around the source tree.
5533 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5535 * Added silc_hash_table_del[_by_context]_ext functions in to the
5536 lib/silcutil/silchashtable.[ch].
5538 Removed silc_hash_table_find_all* routines and added new
5539 silc_hash_table_find_foreach to replace them.
5541 Added silc_hash_table_replace_ext function as extended
5542 replacing function. Separated the simple hash table interface
5543 from the extended hash table interface in the file
5544 lib/silcutil/silchashtable.h.
5546 * Fixed minor bugs and changed it to use some of the new
5547 hash table functions in lib/silccore/idcache.c
5549 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5551 * Added new function silc_hash_table_find_all to return all keys
5552 in the hash table by the specified key. As the hash table is
5553 collision resistant it also makes it possible to have several
5554 duplicate keys in the hash table. This function may be used to
5555 find all of the keys from the hash.
5557 Added user_context arguments to the SilcHashFunction,
5558 SilcHashCompare and SilcHashDestructor to deliver user specified
5561 Added new fuctions silc_hash_table_find[_all]_ext to do
5562 extended lookup with specified hash and compare functions and
5563 specified user contexts.
5565 Added new function silc_hash_table_add_ext to add the key
5566 with specified hash function and user context.
5568 Added new function silc_hash_table_foreach to traverse all
5569 entrys in the hash table. Added SilcHashForeach callback
5572 Added new function silc_hash_table_del_by_context to delete
5573 the entry only if the context associated with the key matches.
5575 Affected files are lib/silcutil/silchashtable.[ch].
5577 * Removed silc_hash_[server/client/channel]_id and added just
5578 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
5579 silc_hash_id_compare to compare two ID's using as the hash table
5580 comparison function. Added also silc_hash_data to hash
5581 binary data and silc_hash_data_compare to compare it.
5583 * Removed silc_idlist_find_client_by_hash as it is not needed
5584 anymore. Affected file silcd/idlist.[ch].
5586 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
5587 to use internally the SilcHashTable. The new ID Cache is a lot
5588 faster than the old one. Some of the ID Cache interface was also
5589 rewritten and obsolete and stupid functions were removed.
5591 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5593 * Added entry_count field to the SilcHashTable to keep the number
5594 of the entries in the table. Implemented the function
5595 silc_hash_table_rehash. Added new function
5596 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
5598 Fixed a minor bug in silc_hash_table_free.
5600 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
5601 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
5602 into the lib/silcutil/silcutil.[ch].
5604 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5606 * Implemented a collision resistant hash table into the
5607 lib/silcutil/silchashtable[ch]. See the header and the source
5608 for the SilcHashTable API.
5610 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5612 * Merged dotconf version 1.0.2 into lib/dotconf.
5614 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5616 * Do not compile anything in lib/silcsim/* if the SIM support
5617 is not enabled. The tree should now compile without problems
5620 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5622 * Compiled the SILC under cygwin. Compiled and tested briefly
5623 without problems. More tests needed. The SIMs didn't compile
5626 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
5628 * Fixed possible crash in silc_get_username in the
5629 lib/silcutil/silcutil.c.
5631 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5633 * Fixed a va_arg in silc/client_ops.c.
5635 * Oops, RC5 routines were named AES and caused some problems
5636 when not using SIM's. Affected file lib/silccrypt/rc5.c.
5638 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5640 * Added new SilcIDIP structure into the lib/silccore/id.h and
5641 replaced the old `ip' fields from all SILC ID's to that type.
5642 This is a step towards IPv6 support.
5644 The silc_id_get_len takes now the ID as an extra argument.
5645 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
5646 both IPv4 and IPv6 based ID's.
5648 The affected files are lib/silccore/id.[ch] and other files
5649 around the tree using these routines.
5651 * Removed the ID length arguments in server from various
5652 silc_server_send_notify_* routines -> they are not needed
5655 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5657 * Fixed memory leak in silc_encode_pem_file in the file
5658 lib/silcutil/silcutil.c.
5660 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5662 * Check minor version as well in the SKE. Affected files are
5663 silcd/protocol.c and lib/silcclient/protocol.c.
5665 * Added --identifier option to the server so that an identifier
5666 can be when creating the public key for the server. Affected
5667 file is silcd/silcd.c.
5669 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
5670 lib/silccrypt/silcpkcs.c.
5672 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5674 * Register default ciphers and stuff when using -C option with
5675 the server. Affected file sildc/silcd.c.
5677 * Put back the servers public key filename format, it is better
5678 than the new one. For now, the client keys are saved with the
5679 new filename format. The affected file silc/client_ops.c.
5681 * Implemented the Cipher API for the rest of the ciphers that
5682 did not implement it or implemented it the wrong way.
5684 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5686 * Register default ciphers and stuff when using the -S option
5687 in the client. Affected file silc/silc.c. Same also when
5688 creating new key pair with -C option.
5690 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5692 * Fixed the silc_verify_public_key client operation function to
5693 save the public keys differently. The fingerprint is now
5694 used as filename and not the hostname. This way also the
5695 client keys are saved uniquely and not with hostnames. The
5696 affected file is silc/client_ops.c.
5698 * Trimmed the silc_hash_fingerprint function to remove extra
5699 whitespaces from the end of the fingerprint. The affected
5700 file is lib/silccrypt/silchash.c.
5704 * Added silc_cipher_register_default function to register all
5705 default ciphers. It can be used when configuration files
5706 does not exist and the application does not want any specific
5707 ciphers in any specific order.
5709 The SilcDList is now used as silc_cipher_list dynamically
5710 allocated cipher list. Removed the static list all together
5711 and now all ciphers must be allocated to the dynamic list.
5712 The silc_cipher_alloc routine was changed to check only the
5715 All silc_cipher_* routines that used to return int returns
5718 The affected files lib/silccrypt/silccrypt.[ch].
5720 * The same thing was done to silc_hash_* as for silc_cipher_*
5721 routines. Affected files lib/silccrypt/silchash.[ch].
5723 * The same thing was done to silc_pkcs_* as for silc_cipher_*
5724 routines. Affected files lib/silccrypt/silcpkcs.[ch].
5725 Added also silc_pkcs_[un]register[_default] functions.
5726 Removed the data_context from the PKCS API.
5728 * Added silc_hmac_register_default function to register default
5729 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
5730 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
5731 to unregister all hmacs at once.
5733 * Register the default ciphers, hash functions, PKCSs and HMACs
5734 if client's configuration file does not exist. The affected
5737 * The client did not load the hash functions from the SIM
5738 modules at all. Added support for this. Affected file is
5739 silc/clientconfig.c.
5741 * When decoding public key with silc_pkcs_public_key_decode, check
5742 the supported algorithm only if PKCS are registered. Affected
5743 file lib/silccrypt/silcpkcs.c. The same was done with the
5744 silc_pkcs_private_key_decode.
5746 * Fixed the SILC List routines to keep the list always in order.
5747 It used to change the list's order when traversing the list but
5748 not it preserves the order. Affected file lib/trq/silclist.h.
5750 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5752 * Added the client library to use the SilcSocketConnection's
5753 reference counter (by silc_socket_dup) to prevent the bug that
5754 the socket object may be freed underneath async operation.
5756 * The name resolv library checking fixes in the configure.in.pre.
5759 * Created new version of the protocol drafts for future
5760 development. The -03 drafts are the ones that will be changed
5761 in the trunk now and the -02 will remain as they are.
5763 * Send list of CUMODE notifys to the router when announcing
5764 the channel users to the router. Affected file silcd/server.c.
5765 If the router receiving channel founder CUMODE for a channel
5766 that already has channel founder it will send CUMODE notify
5767 to the sender to remove the channel founder rights from the
5768 announced client. Affected file silcd/packet_receive.c.
5770 * The CUMODE notify may now use Server ID as well as the entity
5771 who changes the mode. Updated protocool specs.
5773 * Updated INSTALL and README files.
5775 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5777 * New web pages in the http://silc.pspt.fi. The pages was
5782 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5784 * Implemented the [DenyConnectin] config section in the server.
5785 Added silc_server_config_denied_conn to check whether incoming
5786 connection is denied. Affected file silcd/serverconfig.[ch].
5788 * Do not check the ports when checking the incoming configuration
5789 data if the port is 0, meaning any. Affected file is
5790 silcd/serverconfig.c.
5792 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5794 * Fixed buffer overflow in silc_string_compare in the file
5795 lib/silcutil/silcutil.c.
5797 * Fixed double free in silc_server_command_leave in the file
5800 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5802 * Fixed the version checking in the server. Affected file is
5805 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5807 * Fixed the configuration data fetching when accepting new
5808 connections in the server. Affected file silcd/server.c.
5810 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5812 * Added `sender_entry' argument to the function
5813 silc_server_packet_relay_to_channel so that we can check
5814 whether some destination actually belongs to the same route
5815 the sender belongs (ie, we must not resend the packet to the
5816 sender). Affected file silcd/packet_send.[ch].
5818 * Added `servername' field to the SilcClientEntry in the server
5819 to hold the name of the server where client is from. Affected
5820 file is silcd/idlist.h.
5822 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5824 * Moved the channel message encrypting in the router betwen
5825 router connections from silc_server_channel_message to the
5826 silc_server_packet_relay_to_channel since we want to check
5827 whether we have anybody channel before encrypting anything.
5828 Affected files silcd/packet_[receive/send].c.
5830 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5832 * Fixed the [AdminConnection] server config section to support
5833 multiple entries. Affected file silcd/serverconfig.c.
5835 * Added support into the server to check the validity of the
5836 incoming connection before executing any KE or authentication
5839 * The connection configuration is now saved to the KE and
5840 connection auth protocol contexts and not fetched anymore in
5841 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
5843 * The local hosts listenning address and port is also resolved
5844 now when starting the server. We want to have the socket object
5845 to include the real address and port for the listener. Added
5846 new function silc_net_check_local_by_sock into the files
5847 lib/silcutil/silcnet.[ch].
5849 * Fixed a broadcast bug in server -> do not broadcast if we
5852 * Fixed a routing bug. Do not route broadcast packets ever.
5853 Broadcast packets must be processed always and not routed since
5854 they may be destined to some other host than yourself and thus
5855 would get routed without no good reason. Affected file is
5858 * Added function silc_server_config_is_primary_route to check
5859 whether primary router connection has been configured (a router
5860 configuration that we are initiating). If there is not, we
5861 will assume that there is only two routers in the SILC network
5862 and we will use the incoming router connection as our primary
5863 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
5865 * Changed the order of the broadcasting. Broadcast _after_ the
5866 packet has been processed not before. Affected file is
5869 * Fixed a [ClientConnection] parsing bug. The port was never
5870 parsed correctly thus resulting to port 0. Affected file
5871 silcd/serverconfig.c.
5873 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
5874 argument and did not set the broadcast packet flag. Affected
5875 file silcd/packet_send.c. Fixed same bug in the function
5876 silc_server_send_notify as well.
5878 * If we receive NEW_ID packet for our own ID in the server, ignore
5881 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5885 * Removed the nickname from the Private Message Payload.
5886 Updated the code and the protocol specs.
5888 * Updated protocol specs for submitting to the IETF.
5890 * Tweaked the Random Number Generator a bit. Affected file
5891 lib/silccrypt/silcrng.c. Exported a new function
5892 silc_rng_[global]_add_noise which can be used to add more
5895 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5897 * Do not parse packets with different timeout when protocol
5898 is active -> may cause problem with rekey. Affected file
5901 * When server receives signoff notify it must not create
5902 new channel key if the client is on any channels since the
5903 sender of the signoff notify will create it.
5905 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5907 * Added printing of error messages during SKE protocol from the
5908 failure packet sent by server during SKE. Affected file
5911 * Removed the client's failure_callback handling with timeout
5912 and handle it immediately when received.
5914 * The SKE library returned wrong type in SUCCESS and FAILURE
5915 packets. They must be 32 bit MSB not 16 bit MSB.
5917 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5919 * Ok, rewrote the logic of the re-key and now it seems to work.
5920 I tested it on high traffic with frequent re-keys without
5921 problems. Added hmac_receive (and renamed hmac to hmac_send)
5922 in SilcClientConnection in lib/silcclient/client.h and
5923 in SilcIDListData in silcd/idlist.h. Also, removed the
5924 SilcPacketParserContext's cipher and hmac fields as they are
5925 not needed anymore and actually caused some problems when
5926 the ciphers and hmac's changed underneath the packet parser.
5928 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5930 * If re-key protocol is active then process the incoming packets
5931 synchronously since we must assure that icoming packets encrypted
5932 with the old key is processed before the new keys is set to
5933 use. This is true other packets than for REKEY packets.
5934 Affected file silcd/server.c. The same was done to client library
5935 as well, affected file lib/silcclient/client.c.
5937 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5939 * Fixed bug in client and server to accept the force send if
5940 the packet is send from silc_[server/client]_packet_process
5941 function. Otherwise the packets are never delivered, oops.
5943 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5945 * Disable force sending of packets when REKEY protocol is active.
5946 We must assure that no packet is sent directly when rekey is
5947 performed. All packets must be sent through packet queue.
5948 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
5949 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
5950 function is silc_[server/client]_packet_send_real to check
5953 * Replaced the SIM paths from example config files to
5954 /usr/local/modules. Also, make install creates now
5955 /usr/local/silc/logs directory to hold all the SILC server
5958 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5960 * Made the configure.in.pre work on Solaris. Patch by salo.
5962 * Made all ciphers compatible with non-x86 machines. Defined
5963 CBC mode macros into lib/silccrypt/ciphers_def.h.
5965 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5967 * Fixed the make install.
5969 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5971 * When MAC computation fails the silc_packet_decrypt returned 0
5972 even though it was supposed to return -1. Fixed this. The
5973 affected file is lib/silccore/silcpacket.c.
5975 * Do not replace the config files in /etc/silc (in make install)
5976 if they already exist. Affected file ./Makefile.am.
5978 * Do not send re-key packets immediately but through packet queue.
5979 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5981 * Changed silc_net_check_host_by_sock to return FALSE if the
5982 IP/DNS could not be resolved. Though, it returns the IP address
5983 now even if it could not resolve it (but returns also FALSE).
5984 Affected file lib/silcutil/silcnet.[ch].
5986 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5988 * Added silc_pkcs_decode_identifier to decode the public key's
5989 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5990 Added also silc_pkcs_free_identifier. Added also new context
5991 SilcPublicKeyIdentifier.
5993 * Added -S option to the silc client. It is used to dump the
5994 contents of the specified public key file.
5996 * Changed the PKCS api to return the public key length when
5997 setting the public key.
5999 * Fixed a fatal bug in the public and private key file loading.
6000 Affected file lib/silccrypt/silcpkcs.c.
6002 * Execute the packet parsing for client with zero (0) timeout
6003 if the protocol is active. Affected file silcd/server.c.
6005 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6007 * Made the key generation options to the silcd program. Added
6008 -C option, equivalent to client's option.
6010 * Added new [ServerKeys] config section to the server. It
6011 configures the server's public and private key.
6013 * Defined generic Public Key Payload into the protocol
6014 specification to send specific type of public keys and
6017 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
6018 public key or certificate.
6020 * Implemented the GETKEY command to the server and to the
6021 client library and on user interface.
6023 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6025 * Made preliminary `make install' work.
6027 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6029 * Added SilcServerRekey context into silcd/idlist.h.
6031 * Added the PFS support as defined in the specification to the
6032 SKE protocol. Affected files lib/silcske/*.c.
6034 * Added `ske_group' field to the SilcServerRekey context to hold
6035 the number of the SKE group that is used with PFS in re-key.
6036 Affected file silcd/idlist.h.
6038 * Added PFS re-key support to the server. Affected file is
6041 * Added silc_protocol_cancel to cancel execution of the next
6042 state of the protocol. Affected file is
6043 lib/silccore/silcprotocol.[ch].
6045 * Added the re-key support with and without PFS to the client
6046 library. Re-key is performed once in an hour, by default.
6048 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
6049 Added silc_client_rekey_callback and silc_client_rekey_final.
6050 Affected files are lib/silcclient/protocol.[ch] and
6051 lib/silcclient/client.[ch].
6053 * Removed the `hmac_key' and `hmac_key_len' fields from the
6054 SilcClientConnection structure; not needed. Affected file is
6055 lib/silcclient/client.h.
6059 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6061 * Do not ask whether user wants to use the negotiated private key
6062 for private messages, just use it. Affected file is
6063 silc/local_command.c.
6065 * Added `send_enc_key' and `enc_key_len' fields to the
6066 SilcIDListData structure since they are needed in the re-key
6067 phase. Affected file is silcd/idlist.[ch].
6069 * Implemented the simple re-key protocol into the server.
6070 Affected files silcd/server.c and silcd/protocol.[ch]. The
6071 re-key will be performed once in an hour, by default.
6073 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
6074 Added silc_server_rekey, silc_server_rekey_callback and
6075 silc_server_rekey_final.
6077 * Removed Tunneled flag from the protocol. Updated the code
6078 and the specifications.
6080 * Adde `pfs' field to the SilcIDListData to indicate whether
6081 the PFS is to be performed in the re-key. Affected file is
6084 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6086 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
6087 int64 of at least the xintXX size. If void * is less that 4
6088 bytes uint32 * will be used. Defined bool as boolean.
6090 * Changed _ALL_ unsigned long and unsigned int to uint32,
6091 unsgined short to uint16 in the source tree.
6093 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
6094 not handle clients that has entry->data.registered == FALSE.
6095 They are not in the network anymore. Affected file is
6098 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6100 * Implemented the sending of the SERVER_SIGNOFF notify in the
6101 server. Affected file is silcd/server.c.
6103 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
6104 Added also silc_notify_payload_encode_args into the
6105 lib/silccore/silcnotify.[ch].
6107 * Implemented ther SERVER_SIGNOFF notify handling in the server.
6108 Affected file silcd/packet_receive.c.
6110 * Implemented the SERVER_SIGNOFF notify handling in the client
6111 library. Affected file lib/silcclient/client_notify.c. Also,
6112 implemnted the printing of the SERVER_SIGNOFF info to the
6113 application. Affected file silc/client_ops.c.
6115 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
6116 if the deleting was successful. Affected file silcd/idlist.[ch].
6118 * Added support for public key authentication in the connection
6119 authentication protocol in the client library. Affected file
6120 lib/silcclient/protocol.c.
6122 * Changed the server's silc_idlist_get_clients_by_* interface
6123 to support already allocated array so that new entries may be
6124 added to pre-allocated array. Affected file silcd/idlist.[ch].
6125 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
6126 and command replies.
6128 * All command reply functions in the server now calls the
6129 pending command callback even if error occured. This way the
6130 error will be delivered to the client as well. Affected files
6131 silcd/command.c and silcd/command_reply.c.
6133 * Fixed INFO command to return local server's info if no server
6134 was provided. Affected file lib/silcclient/command.c.
6136 * Removed RESTART command for good. Updated the code and the
6139 * Rewrote parts of the task system. It is a bit simpler now.
6140 Removed unsued task priorities. The affected files are
6141 lib/silcutil/silctask.[ch].
6143 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6145 * Moved the USERS printing from the library to the application.
6146 Affected files lib/silcclient/command.c and silc/client_ops.c.
6148 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6152 * Added channel key re-key support. The re-key is perfomed
6153 only by the router and is done once in an hour. Added `rekey'
6154 field to the SilcChannelEntry in the server. Affected files
6155 silcd/server.c and silcd/idlist.h.
6157 * Added silc_task_unregister_by_context into the file
6158 lib/silcutil/silctask.[ch].
6160 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6162 * Added SILC_UMODE_GONE mode to indicate when the client is not
6163 present in the SILC network. Added also support to the local
6164 command AWAY that will set this mode. Added support of showing
6165 "xxx is gone" in WHOIS command. The USERS command shows the
6166 gone status as well.
6168 * Fixed setting server and router operator privileges in the
6169 server's UMODE command. Affected file silcd/command.c.
6171 * Merged the SKE KE1 and KE2 payloads into one payload. The
6172 new KE payload is equivalent to the old KE2 payload.
6174 Cleaned up the SKE Start Payload parsing. It now uses the
6175 simple buffer unformatting to do the parsing. A lot faster
6178 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
6179 to the SKE that is used to indicate whether both of the SKE
6180 parties should perform authentication. By default only the
6181 responder performs authentication. By setting this flag also
6182 the initiator must do authentication. By default it is unset
6183 since in normal SKE case, client to server connection, only
6184 the responder should do authentication. When doing SKE between
6185 two clients both should perform authentication. Updated the
6186 code and the protocol specs.
6188 * A little fix to IDENTIFY command in the server. Search the
6189 client first by hash not nickname. Affected file is
6192 * Fixed the silc_client_close_connection to support closing
6193 the client to client connections wihtout deleting too much
6194 data. Affected file lib/silcclient/client.c.
6196 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
6197 are received if protocol used to be active but is not anymore
6198 the application would crash due to NULL pointer dereference.
6199 Affected files silcd/server.c and lib/silcclient/client.c.
6201 * Added `hash' field to the SilcClientConnection to include
6202 the hash function negotiated in the SKE protocol.
6204 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
6205 to set the channel founder authentication data. A client can
6206 claim the founder rights later by providing the authentication
6207 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
6208 This way the channel founder can regain the channel founder
6209 privileges even it is left the channel. This works only on
6210 local server and the client must be connected to the same
6211 server to be able to regain the founder rights. Updated the
6212 protocol specs accordingly.
6214 Added support to the CMODE command in the client to set the
6215 founder auth data. Read the README to see how to set it.
6217 Added support to the CUMODE command to claim the founder
6218 rights. Read the README to see how to do it.
6220 Added support for the founder authentication to the Channel
6221 Entry in the server. Affected file silcd/idlist.h.
6223 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
6224 server's CMODE command. Affected file silcd/command.c.
6226 * Added the following new functions into lib/silccore/silcauth.[ch]:
6227 silc_auth_get_method and silc_auth_get_data.
6229 * The server now saves the remote hosts public key to the
6230 SilcIDListData pointer. Affected file silcd/protocol.c.
6232 * The normal server now does not remove the channel entry from
6233 the cache if the founder authentication data is set. It used
6234 to remove it if the founder was the last one on the channel on
6235 the server and left the channel. The auth data is saved and
6236 if the channel is re-joined later the old entry is used with
6237 the old auth data. Affected files silcd/command_reply.c and
6240 * Removed the `pkcs' field from the SilcIDListData structure
6241 in the server; it is not used. Affected file silcd/idlist.h.
6243 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6245 * Fixed packet processing on slow links. Partial packets were
6246 never re-processed because the incoming data buffer was cleared
6247 by the application. Application must not directly clear the
6248 sock->inbuf, the packet processing routines handle it. Fixed
6249 this in client library and in server.
6251 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6253 * Fixed the WHOIS and IDENTIFY send reply function to really
6254 check whether to send list or just one entry. Affected file
6257 * Cleaned up the LEAVE command's channel key distribution. The
6258 affected file silcd/command.c.
6260 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
6261 can enforce the channel mode as well. In that case the ID
6262 includes the ID of the server. The code now enforces the
6263 mode change if the router have different mode than the server.
6265 * The notify client operation with CMODE_CHANGE notify can now
6266 return NULL client_entry pointer if the CMODE was not changed
6267 by client. Application must check for this.
6269 * Added <Server ID> argument to INFO command to support server
6270 info fetching by Server ID.
6272 * Added silc_server_announce_get_channel_users to get assembled
6273 packets of channel users of the specified channel. Affected
6274 file silcd/server.[ch].
6276 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
6277 was freed underneath the ID Cache.
6279 * Re-announce clients when the server received CHANNEL_CHANGE
6280 notify from the router. Affected file silcd/packet_send.c.
6282 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6284 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
6285 crashed since it did not handle the fact that there is no cipher
6286 called "3" and didn't check the error condition. Now fixed.
6288 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
6289 flag. It can be used to send message requests.
6291 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6293 * Implemented the RESTART command in the client.
6295 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
6296 notice type messages. Added notice printing to the user
6299 * The channel keys are not re-generated if the channel's mode
6300 is PRIVKEY, ie private key on the channel exists. Affected
6301 files silcd/server.c and silcd/command.c.
6303 * Fixed a little bug in channel message delivery when channel
6304 private keys are set in the server. Affected file is
6305 silcd/packet_send.c.
6307 * Changed the setting on channel->on_channel = TRUE from the
6308 silc_client_save_channel_key to the JOIN command reply. The
6309 key payload is not received if the private channel key is set.
6310 Affected file lib/silcclient/command_reply.c and the
6311 lib/silcclient/client_channel.c.
6313 * When the CMODE_CHANGE notify is sent and the channel private
6314 key mode is removed the channel key must be re-generated in
6315 other cells as well. Added this support for the router in the
6316 silcd/packet_receive.c.
6318 * Added new local command NOTICE to send notice message on
6319 channel. Affected file silc/local_command.[ch].
6321 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6323 * Added new local command ME to the client. It is used to send
6324 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
6325 some action. Affected file silc/local_command.[ch].
6327 * Changed channel_message and private_message client operations
6328 to deliver the message flags to the application. Added also
6329 the `flags' arguments to the silc_client_send_channel_message
6330 and silc_client_send_private_message functions. Affected file
6333 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6335 * Redefined the Private Message Payload to support private message
6336 keys and to support the new private message flags. Updated
6337 the protocol specs. Flags makes it possible to have for example
6338 CTCP style messages.
6340 * Added new type SilcPrivateMessagePayload and defined an API
6341 for it in the lib/silcclient/silcprivate.[ch].
6343 * Tested private message private keys successfully. Tested the
6344 private message key set, unset and list commands with the new
6347 * Redefined the Channel Message Payload to include the channel
6348 message flags (equal with private message flags) to support
6349 for example CTCP style messages.
6351 * Defined some of the message (for channel and private message)
6352 flags. Updated the protocol specs and added the flags to the
6353 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
6355 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6357 * Added SilcKeyAgreementStatus type to the key agreement routines
6358 to indicate the current status and error if one occured.
6359 The status types are defined in the lib/silcclient/silcapi.h.
6361 * Added new local command KEY that is used to set and unset private
6362 keys for channels, set and unset private keys for private messages
6363 with remote clients and to send key agreement requests and
6364 negotiate the key agreement protocol with remote client. The
6365 key agreement is supported only to negotiate private message keys,
6366 it currently cannot be used to negotiate private keys for channels,
6367 as it is not convenient for that purpose.
6369 * Fixed a minor pending callback setting bug in the function
6370 silc_client_get_client_by_id_resolve, now the function works.
6371 Affected file lib/silcclient/idlist.c.
6373 * Added function silc_net_get_local_port to get local bound
6374 port by socket. Added to lib/silcutil/silcnet.[ch].
6376 * Added `sockets' and `sockets_count' fields to the SilcClient
6377 object. They hold the sockets of the listenning sockets in
6378 the client. Listenning sockets may be for example the key
6379 agreement server. Affected file lib/silcclient/client.[ch].
6380 Added functions the silc_client_add_socket and the
6381 silc_client_del_socket. They are exported to the application
6384 * Added ~./silc/clientkeys to support other client's public keys.
6386 * Renamed verify_server_key client operation to verify_public_key
6387 and added one argument to indicate the type of the connection
6388 (server, client etc.).
6390 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6392 * Added silc_server_connection_auth_request to handle the
6393 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
6394 silcd/packet_receive.[ch].
6396 * Added silc_server_send_connection_auth_request into the
6397 silcd/packet_send.c to send the connection auth request packet.
6399 * Cleaned up the silcd/protocol.c a bit and fixed some memory
6402 * Fixed the public key authentication in responder side in the
6403 server. The `auth_data' pointer includes the SilcPublicKey
6404 not the path to the public key. Affected file silcd/protocol.c.
6406 * Implemented the public key authentication in the initiator side
6407 in the server. Affected file silcd/protocol.c.
6409 * Removed the [RedirectClient] config section from the server
6410 configuration. Is not needed and I don't want to implement it.
6412 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6414 * Cleaned up the CMODE command in the server. It now works
6415 correctly and supports all the modes defined in the protocol.
6416 Affected file is silcd/command.c.
6418 * Added `hmac_name' field to the SilcChannelEntry in the server
6419 to hold the default HMAC of the channel. It can be set when
6420 creating the channel (with JOIN command). Affected files
6423 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
6424 type to indicate the change of the current cipher and hmac
6425 on the channel. Client can safely ignore the <cipher> argument
6426 (if it chooses to do so) since the CHANNEL_KEY packet will
6427 force the channel key change anyway. The <hmac> argument is
6428 important since the client is responsible of setting the new
6429 HMAC and the hmac key into use.
6431 * Fixed the CMODE command in the client library as well.
6433 * Tested CMODE command in router environment successfully.
6435 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6437 * Show the version of the remote client (or server) when connecting
6438 to the server. It is logged to the log file. Affected file
6439 is silcd/protocol.c.
6441 * Fixed the KILLED notify handling in the client library. The
6442 client must be removed from all channels when receiving the
6445 Also, do not remove the client entry when giving the KILL
6446 command but when the KILLED notify is received.
6448 * Removed silc_idlist_find_client_by_nickname from the server.
6449 Not needed anymore. Affected files silcd/idlist.[ch].
6451 * Implemented the CHANNEL_CHANGE notify type handling to the
6452 server. Affected file silcd/server.c.
6456 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6458 * Added silc_server_send_notify_invite to send the INVITE
6459 notify between routers.
6461 * Implemented the INVITE command correctly to the server.
6463 * Implemented the INVITE notify type handling in the server.
6465 * Implemented the INVITE command to the client library and on the
6468 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6470 * Added function silc_server_get_client_resolve to find the
6471 client entry by ID from all ID lists and then resolve it
6472 (using WHOIS) if it cannot be found. Affected file is
6475 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6477 * Implemented the BAN command to the client library.
6479 * The JOIN command in the server now checks the invite list
6482 * Changed the silc_command_reply_payload_encode_va and the
6483 silc_command_payload_encode_va to support that if argument is
6484 NULL it ignores and checks the next argument. Affected file
6485 lib/silccore/silccommand.c.
6487 * Added silc_server_send_notify_ban to send the BAN notify
6488 type between routers.
6490 * Chaned the silc_notify_payload_encode to support that if
6491 argument is NULL it ignores and checks the next argument.
6492 Affected file lib/silccore/silcnotify.c.
6494 * Tested ban lists in router environment successfully.
6496 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6498 * Implemented BAN command to the server, in silcd/command.[ch].
6500 * Removed the BAN and INVITE_LIST modes from the CMODE command
6503 * Added function silc_string_match to regex match two strings.
6504 Affected files lib/silcutil/silcutil.[ch].
6506 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6508 * Redefined parts of the SilcChannelEntry in the server to support
6509 the new ban and invite lists.
6511 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6513 * Redefined the INVITE command. The same command can be used to
6514 invite individuals to the channel but also to manage the invite
6515 list of the channel (to add to and remove from the invite list).
6516 Updated the protocol specs.
6518 * Added new command SILC_COMMAND_BAN that can be used to manage
6519 the ban list of the channel. Updated the protocol specs.
6521 * Removed the channel modes: the SILC_CMODE_BAN and the
6522 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
6523 in the CMODE command. The equivalent features are now available
6524 using INVITE and BAN commands. Updated the protocol specs.
6526 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
6527 in the network about change in the current ban list. The notify
6528 type is not used by the client.
6530 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
6531 support the invite lists.
6533 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6535 * Added new function silc_string_regexify that converts string
6536 including wildcard characters into regex string that can
6537 be used by the GNU regex library. Added into the file
6538 lib/silcutil/silcutil.[ch].
6540 Added silc_string_regex_combine to combine to regex strings
6541 into one so that they can be used as one regex string by
6542 the GNU regex library. Added into the file
6543 lib/silcutil/silcutil.[ch].
6545 Added silc_string_regex_match to match two strings. It returns
6546 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
6548 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6550 * Imported GNU regex to the soruce tree into lib/contrib.
6551 Fixed some compiler warning from the regex.c.
6553 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6555 * Fixed MOTD command in the server to work in router environment.
6557 * Fixed the MOTD command in the client library to support
6558 the server argument in the command.
6560 * Added `nickname_len' argument to the silc_idlist_add_client
6561 in the server, as the `nickname' argument may be binary data
6564 * Added silc_idlist_get_channels to return all channels from
6567 * Implemented LIST command to the server. Affected file is
6570 * Implemented the LIST command to the client library and on the
6573 * Added [<user count>] argument to the LIST command reply.
6574 With private channels the user count is not shown.
6576 * Updated TODO and README.
6578 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6580 * The client entry's data.registered must be TRUE even with
6581 global client entry on global client list. The data.registered
6582 is used to check whether the client is anymore in the network,
6583 for example with WHOWAS command so it must be valid.
6585 * Fixed the WHOWAS command in the server. It now actually works
6586 in router environment. Added function into silcd/command_reply.c
6587 silc_server_command_reply_whowas_save.
6589 * Added silc_idlist_purge function to the silcd/idlist.c
6590 to periodically purge the ID Cache.
6592 * Fixed INFO command in the server. It works now in router
6593 environment. Added <server name> argument to the INFO command
6594 reply. Updated the protocol specs.
6596 * Fixed minor bug in silc_idcache_purge to not purge if the
6597 expire value is zero.
6599 * Fixed various bugs in WHOIS and IDENTIFY command handling as
6600 they were buggy because of the WHOWAS information.
6602 * Fixed local command MSG to handle the async resolving of
6603 the remote client properly. It used to fail the first MSG.
6604 Affected file silc/local_command.c.
6606 * Added `data_len' field to SilcIDCache context.
6608 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6610 * Update TODO. Todo in commands in the server.
6612 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6614 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
6615 used by routers as broadcast packet to inform other routers
6616 about the changed user mode.
6618 Implemented the notify handling in the server. Affected file is
6619 silcd/packet_receive.c. Added the function
6620 silc_server_send_notify_umode to the silcd/packet_send.[ch].
6622 * Added new generic Channel Payload and deprecated the New Channel
6623 Payload. The New Channel Payload is now the generic Channel
6626 * Added new argument `mode' to the silc_server_send_new_channel
6627 as it is required in the Channel Payload now.
6629 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
6630 and created a new and real SilChannelPayload to represent the
6631 new generic Channel Payload. Implemented the encode/decode
6632 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
6634 * Added silc_server_get_client_channel_list to return the list
6635 of channels the client has joined for WHOIS command reply.
6636 Affected file silcd/server.[ch].
6638 * Implemented the channel list sending in the WHOIS command reply
6639 in server and in the client.
6641 Implemented the channel list displaying on the user interface
6642 as well. Affected file silc/client_ops.c.
6644 * Added silc_channel_payload_parse_list to parse list of Channel
6645 Payloads. It returns SilcDList list of SilcChannelPayloads.
6646 Client for example can use this function to parse the list of
6647 channels it receives in the WHOIS command reply. The caller
6648 must free the list by calling silc_channel_payload_list_free.
6649 Affected files lib/silccore/silcchannel.[ch].
6651 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6653 * Added one new argument <user mode> to the WHOIS command reply
6654 to return the mode of the user in SILC. Updated the protocol
6657 Implemented it to the server and client.
6659 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6661 * Fixed the mode printing on the user interface on joining.
6662 Affected file silc/client_ops.c.
6664 * Implemented the UMODE command and user modes in general to the
6665 client library and to the user interface.
6667 * Implemented the UMODE command to the server.
6669 * The server now sends UNKNOWN_COMMAND error status if client sends
6670 unknown command. Affected file silcd/command.c.
6672 * All server commands now handle the command identifier the right
6673 way when sending the command reply to the client. The client can
6674 use to identify the command replies with the identifier.
6676 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6678 * Added silc_server_get_client_route to resolve the route to
6679 the client indicated by the client ID. Affected file is
6682 * Added silc_server_relay_packet as general function to relay
6683 packet to arbitrary destination. This deprecates functions
6684 like _send_private_message_key, _relay_notify etc. Affected
6685 file is silcd/packet_send.[ch].
6687 Removed silc_server_send_key_agreement,
6688 silc_server_send_private_message_key and
6689 silc_server_packet_relay_notify functions from the file
6690 silcd/packet_send.[ch].
6694 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
6695 server. Affected file silcd/packet_receive.[ch].
6697 * Implemented the KILL command to the client. Implemented the
6698 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
6699 Affected files lib/silcclient/command[_reply].c and
6700 lib/silcclient/client_notify.c. Implemented the KILL notify
6701 printing in the user inteface.
6703 * Fixed a lot silc_parse_nick memory leaks from the client
6704 library in the file lib/silcclient/command.c.
6706 * Changed the silc_server_send_notify_on_channels's `sender'
6707 argument from SilcSocketConnection to SilcClientEntry to
6708 check the sender as entry and not as connection object and not
6709 to send to the client provided as argument. The affected file
6710 is silcd/packet_send.[ch].
6712 * The notify packets that are destined directly to the client used
6713 to not to be processed by the server. Now changed that and the
6714 server processes all notify packets. After relaying the packet
6715 to the client the notify packet is processed in the server.
6717 * The silc_server_free_client_data now checks whether there is
6718 pending outgoing traffic for the client and purges the data to
6719 the network before removing the client entry.
6721 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6723 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
6724 an client is killed from the SILC Network. Updated the protocol
6727 Added new function silc_server_send_notify_killed to the
6728 silcd/packet_send.[ch].
6730 * Added function silc_server_packet_relay_notify to relay notify
6731 packets that are destined directly to a client. In this case
6732 the server does not process the notify packets but merely relays
6733 it to the client. Affected file silcd/packet_send.[ch].
6735 Added also silc_server_packet_process_relay_notify to check
6736 whereto relay the notify. Affected file is
6737 silcd/packet_receive.[ch].
6739 * Implemented the KILL command to the server.
6743 * Added the backup schema desgined last fall to the protocol
6744 specs for everyone to see. The specification is in the
6745 *-spec-xx.txt draft and the packet type definitions for the
6746 backup routers is in *-pp-xx.txt draft. Thusly, added also
6747 new packet type SILC_PACKET_CELL_ROUTERS.
6749 * A big security problem in the implementation discovered. The
6750 signoff of an client did not cause new channel key generation
6751 which it of course should've done. The channel keys must be
6752 always re-generated when client leaves (or signoffs) the channel.
6753 The silc_server_remove_from_channels funtion now handles
6754 the channel key re-generation.
6756 * Added `sender' argument to the silc_server_send_notify_on_channels
6757 to not to send the client provided as argument. Affected file
6758 silcd/packet_send.[ch].
6760 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6762 * Implemented OPER and SILCOPER commands into the server and
6765 * Added silc_auth_verify and silc_auth_verify_data to verify
6766 the authentication directly from the authentication payload.
6767 It supports verifying both passphrase and public key based
6768 authentication. Affected file lib/silccore/silcauth.[ch].
6770 * Added `hash' field to the SilcIDListData structure. It is the
6771 hash negotiated in the SKE protocol. Affected file is
6774 * Slight redesigning of the SilcAuthPayload handling routines.
6775 Do not send SilcPKCS but SilcPublicKey as argument.
6777 * Implemented the public key authentication support to the
6778 serverconfig. The public key is loaded from the provided path
6779 and saved as authentication data to void * pointer. Thus,
6780 changed the unsigned char *auth_data to void *auth_data;
6782 * Fixed SHUTDOWN command to send the reply before the server
6783 is shutdown. :) Affected file silcd/command.c.
6785 * Fixed fatal bug in CONNECT command. The hostname was invalid
6786 memory and server crashed. Affected file silcd/command.c.
6788 * Fixed fatal bug in CLOSE command. The server_entry became
6789 invalid but was referenced later in the command. Affected file
6792 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6794 * Fixed fatal bug in failure packet handling. Server ignored
6795 the failure and thus crashed when it came.
6799 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6801 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
6802 that the command may be executed only once in (about) 2 seconds.
6803 The old SILC_CF_LAG flag is same but allows command bursts up
6804 to five before limiting.
6806 Added the support for CF_LAG and CF_LAG_STRICT flags to the
6807 server code. Various commands now includes the CF_LAG_STRICT
6808 flag to disallow any kind of miss-use of the command.
6810 * Fixed the silc_buffer_unformat to not to allocate any data
6811 if the length of the data is zero. It used to allocate the
6812 length + 1. Affected file lib/silcutil/silcbuffmt.c.
6814 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6816 * Changed the format of AdminConnection configuration section
6817 in the server. Added username of the admin to the format.
6818 Affected files silcd/serverconfig.[ch].
6820 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
6821 to return admin configuration data by host, username and/or
6824 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6826 * Implemented WHOWAS command to the server. Added the functions:
6828 silc_server_command_whowas_parse,
6829 silc_server_command_whowas_send_reply,
6830 silc_server_command_whowas_from_client and
6831 silc_server_command_whowas_from_server
6833 * Added <Client ID> argument to the WHOWAS command reply. Updated
6834 the protocol specs accordingly.
6836 * Implemented WHOWAS command and command_reply to the client
6839 Implemented the WHOWAS printing on the user interface.
6841 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6843 * Added new argument to the WHOWAS command reply, the real name.
6844 It is an optional argument. Updated the protocol specs.
6846 * Added SilcIDCacheDestructor callback that is registered when
6847 the SilcIDCache is allocated. The callback is called when
6848 an cache entry in the ID Cache expires, or is purged from the
6849 cache. Added into lib/silccore/idcache.[ch].
6851 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
6852 to destruct the client entries when the cache entry expires.
6853 Other ID Cache's in server and in the client library ignores
6856 * If the ID Cache entry's `expire' field is zero then the entry
6857 never expires. Added boolean `expire' argument to the
6858 silc_idcache_add function in the lib/silccore/idcache.[ch].
6859 If it is TRUE the default expiry value is used.
6861 * Added silc_server_free_client_data_timeout that is registered
6862 when client disconnects. By default for 5 minutes we preserve
6863 the client entry for history - for WHOWAS command.
6865 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6867 * Added support to the server to enforce that commands are not
6868 executed more than once in 2 seconds. If server receives
6869 commands from client more frequently, timeout is registered
6870 to process the commands. Affected file silcd/command.c.
6871 Added new function silc_server_command_process_timeout.
6873 * Changed NICK_NOTIFY handling in client library to check that
6874 if the client's nickname was changed, so there is no need to
6875 resolve anything from the server.
6877 * Removed error printing from the WHOIS and IDENTIFY commands.
6878 If error occurs then it is ignored silently in the client library.
6879 The application, however, may map the received error to
6880 human readable error string. The application currently maps
6881 the NO_SUCH_NICKNAME error to string.
6883 * Made the command status message public to the application. Moved
6884 them from lib/silcclient/command_reply.c to
6885 lib/silcclient/command_reply.h. The application can map the
6886 received command status to the string with the
6887 silc_client_command_status_message function.
6889 * Added check to the server to check that client's ID is same
6890 as the Source ID in the packet the client sent. They must
6893 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6895 * Added dist-bzip hook to the Makefile.am to make bzip2
6896 compressed distributions.
6898 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6900 * Server now enforces the maximum length for the nickname and
6901 the channel as protocol specification dictates. 128 bytes for
6902 nickname and 256 bytes for channel name.
6904 * Moved the WHOIS printing to the application. The client libary
6905 does not print out the WHOIS information anymore, the application
6906 must do it. Renamed silc_client_command_reply_whois_print to
6907 the silc_client_command_reply_whois_save.
6909 The client's idle time is also sent to the application now, and
6910 the idle is shown on screen.
6912 * Added silc_client_command_reply_identify_save to save the
6913 received IDENTIFY entries.
6915 * Do not check for channel private keys in message sending and
6916 reception if the channel does not have the PRIVKEY mode set.
6917 Affected file lib/silclient/client_channel.c.
6919 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6921 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
6922 just surfaced after chaning the JOIN procedure.
6924 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6926 * Added silc_client_get_clients_by_list to get client entries
6927 from Client ID list, that is returned for example by JOIN
6928 and USERS command replies. The application should use this
6929 function for example when JOIN command reply is received to
6930 resolve the clients already on the channel (library does not
6931 do that anymore as USERS command reply is not used in the JOIN
6932 procedure anymore). Affected files lib/silcclient/silcapi.h and
6933 lib/silcclient/idlist.c.
6935 * JOIN command reply and USERS command reply returns now SilcBuffer
6936 pointers instead of unsigned char pointers when returning
6937 the client list and mode list.
6939 * Added <Client ID> argument to the JOIN command reply, mainly
6940 for the server to identify for which client the command was
6941 originally sent. Updated protocol specs accordingly.
6943 * Added SilcDlist private_key pointer to the SilcChannelEntry
6944 in the client to support the channel private keys. Affected
6945 file is lib/silcclient/idlist.h.
6947 * Added SilcChannelPrivateKey argument to the function
6948 silc_client_send_channel_message so that application can choose
6949 to use specific private ke if it wants to. If it is not provided,
6950 the normal channel key is used, unless private keys are set.
6951 In this case the first (key that was added first) is used
6952 as the encryption key.
6954 * Implemented the support for channel private key handling.
6955 Implemented the following functions:
6957 silc_client_add_channel_private_key,
6958 silc_client_del_channel_private_keys,
6959 silc_client_del_channel_private_key,
6960 silc_client_list_channel_private_keys and
6961 silc_client_free_channel_private_keys
6963 Affected file lib/silcclient/client_channel.c.
6965 * Added the support for the private keys in the channel message
6966 sending and encryption and in the message reception and
6967 decryption. Affected funtions are
6968 silc_client_send_channel_message and silc_client_channel_message.
6970 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6972 * Added SKE's key verify callback to the client library's
6973 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6975 * Removed the statement that server (or router) must send USERS
6976 command reply when joining to the channel so that the client
6977 knows who are on the channel. Instead, the client list and
6978 client's mode list is now sent in the JOIN command reply to the
6979 client who joined channel. This is better solution.
6981 * Added function silc_server_get_users_on_channel and function
6982 silc_server_save_users_on_channel to the silcd/server.[ch].
6984 * Removed function silc_server_command_send_users from the
6987 * Do not show topic on the client library anymore. The topic is
6988 sent in the command reply notify to the application and the
6989 application must show the topic now.
6991 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6993 * Added client searching by nickname hash into the IDENTIFY and
6994 WHOIS commands in the server as they were clearly missing from
6995 them. Affected file is silcd/command.c.
6997 * Fixed a bug in private message receiving in the client library.
6998 The remote ID was freed and it wasn't supposed, now it is
7001 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7003 * Minor fix to the channel payload; allocate the data area, as it
7004 needs to be of specific length.
7006 * If the key agreement port is zero then the operating
7007 system will define the bound port. Affected files are
7008 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
7010 * Added new function silc_channel_payload_decrypt into the file
7011 lib/silccore/silcchannel.[ch].
7013 * Moved the channel message etc, check from silc_packet_decrypt
7014 to applications. The library calls now a generic
7015 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
7016 when the packet is either normal or special. This was done to
7017 allow more wide range of checking that was not allowed when
7018 the code was in library. Now applications can do virtually any
7019 checks to the packet and return to the library the decision how
7020 the packet should be processed. Affected files are
7021 lib/silccore/silcpacket.[ch].
7023 Added silc_server_packet_decrypt_check to the server and
7024 silc_client_packet_decrypt_check to the client library.
7026 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
7027 to send with specified source and destination information.
7029 * Channel message delivery between routers was broken after the
7030 channel key distribution was fixed earlier. The channel key
7031 was used be to distributed to other routers as well which is not
7032 allowed by the protocol. Now this is fixed and channel keys
7033 really are cell specific and the channel message delivery between
7034 routers comply with the protocol specification.
7036 * Fixed various commands in server to check also the global list
7037 for the channel entry and not just the local list. The affected
7038 file silcd/command.c.
7040 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7042 * Added assert()s to buffer formatting and unformatting routines
7043 to assert (if --enable-debug) when error occurs. Affected
7044 file: lib/silcutil/silcbuffmt.c.
7046 * Changed to auto-reconnect to check whether the remote host is
7047 router and register the re-connect timeout if it is. It used
7048 to check that whether we are normal server, but router must do
7049 auto-reconnect with another router as well. Affected file
7052 * Removed the [<key len>] option from CMODE command as the cipher
7053 name decides the key length, nowadays. See the defined ciphers
7054 from the protocol specification.
7056 * Added [<hmac>] option to the CMODE command to define the HMAC
7057 for the channel. Added SILC_CMODE_HMAC channel mode.
7059 * Added [<hmac>] option for the JOIN command so that user can
7060 select which HMAC is used to compute the MACs of the channel
7063 * Added Hmac field to the Channel Message Payload. The integrity
7064 of plaintext channel messages are now protected by computing
7065 MAC of the message and attaching the MAC to the payload. The
7066 MAC is encrypted. Now, it is clear that this causes some
7067 overhead to the size of the packet but rationale for this is that
7068 now the receiver can verify whether the channel message decrypted
7069 correctly and also when private keys are set for the channel the
7070 receiver can decrypt the packet with several keys and check from
7071 the MAC which key decrypted the message correctly.
7073 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
7074 lib/silccrypt/silccipher.[ch].
7076 * Added silc_hash_len to return the digest length into the
7077 lib/silcrypt/silchash.[ch].
7079 * Rewrote parts of Silc Channel Payload interface in the
7080 lib/silccore/silcchannel.[ch]. The encode function now also
7081 encrypts the packet and parse function decrypts it.
7083 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7085 * Fixed a minor formatting bug in the SKE's key material processing.
7086 It actually might have processed the keys wrong way resulting
7089 * Redefined the mandatory HMAC algorithms and added new algorithms.
7090 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
7091 and hmac-md5 truncated to 96 bits. The mandatory is now
7092 hmac-sha1-96. Rest are optional (including the one that used
7093 to be mandatory). Rationale for this is that the truncated HMAC
7094 length is sufficient from security point of view and can actually
7095 make the attack against the HMAC harder. Also, the truncated
7096 HMAC causes less overhead to the packets. See the RFC2104 for
7099 * Added new [hmac] configuration section. The SKE used to use
7100 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
7101 is of course wrong. The official names that must be proposed in
7102 the SKE are the ones defined in the protocol specification
7103 (hmac-sha1-96 for example). The user can configure any hmac
7104 using any hash function configured in the [hash] section. At
7105 least, the mandatory must be configured.
7107 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
7109 * Added HMAC list to the SKE proposal list. It has now both
7110 hash algorithm list and HMAC list. This makes the protocol
7111 incompatible with previous versions. The SKE now seems to work
7112 the way it is supposed to work, for the first time actually.
7114 * Defined plain Hash algorithms to the protocol specification.
7117 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7119 * Implemented support for key agreement packets into the server.
7120 Added functions silc_server_key_agreement and
7121 silc_server_send_key_agreement. Other than these functions,
7122 server has nothing to do with this packet.
7124 * Added support for private message key packets into the server.
7125 Added functions silc_server_private_message_key and
7126 silc_server_send_private_message_key.
7130 * Changed the silc_[client|server]_protocol_ke_set_keys to be
7131 called in the protocol's final callback instead in the END
7132 protocol state. This makes a little more sense and in the same
7133 time in client we can use the same protocol routines for normal
7134 key exchange and to key agreement packet handling as well.
7136 * Added to both client's and server's KE protocol context the
7137 SilcSKEKeyMaterial pointer to save the key material. We will
7138 bring the key material to the protocol's final callback by doing
7139 this. The final callback must free the key material.
7141 * Added SKE's packet_send callback into client's KE protocol
7142 context so that the caller can choose what packet sending function
7143 is used. This way we can use different packet sending when
7144 doing normal SKE when doing key agreement packet handling (in
7145 the key agreement packet handling we do not want to encrypt
7148 * Implemented the responder side of the key agreement routines
7149 in the client. The client can now bind to specified port and
7150 accept incoming key negotiation. The key material is passed
7151 to the application after the protocol is over.
7153 * Implemented the processing of incoming Key Agreement packet
7154 in the client. Added function silc_client_key_agreement to
7157 * Implemented the intiator side of the key agreement routines
7158 in the client. The client can now initiate key agreement with
7159 another remote client. The key material is passed to the
7160 application after the protocol is over.
7162 * Created client_keyagr.c to include all the key agreement
7165 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
7166 SILC_TASK_CALLBACK except that it is not static.
7168 * Created client_notify.c and moved the Notify packet handling
7169 from the client.[ch] into that file.
7171 * Created client_prvmsg.c and moved all private message and
7172 private message key routines from the client.[ch] into that file.
7174 * Create client_channel.c and moved all channel message and
7175 channel private key routines from the client.[ch] into that file.
7177 * Changed silc_client_get_client_by_id_resolve to resolve with
7178 WHOIS command instead of IDENTIFY command, in the file
7179 lib/silclient/idlist.c.
7181 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7183 * Implemented the SKE's responder side to the Client library.
7185 * When FAILURE is received to the protocol do not trust it
7186 blindly. Register a timeout to wait whether the remote closes
7187 the connection as it should do it, only after that process the
7188 actual failure. This was changed to both client and server.
7190 * Added client_internal.h to include some of the structures
7191 there instead of client.h in lib/silcclient/.
7193 * Added function silc_task_unregister_by_callback to unregister
7194 timeouts by the callback function.
7196 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7198 * Some "Incomplete WHOIS info" errors has been appearing on the
7199 log files. Took away the entry->userinfo check from WHOIS
7200 reply sending. The entry->userinfo is now " " if client did not
7201 provide one. I thought this was fixed earlier but something
7202 is wrong still. Let's see if the error still appears.
7204 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7206 * Fixed a minor bug in the login when the channel key is
7207 re-generated in the server. It used to generate the key in
7208 wrong order and thus caused problems in the channel traffic.
7210 * Fixed a minor bug in channel key distsribution after
7211 KICK command. The key was not sent to the router even though
7214 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7216 * Added silc_ske_process_key_material_data as generic routine
7217 to process any key material as the SILC protocol dictates. The
7218 function is used by the actual SKE library but can be used by
7219 applications as well. This relates to the private message keys
7220 and the channel private keys since they must be processed the
7221 same way the normal SILC session keys. The protocol dictates
7222 this. Affected files: lib/silcske/silcske.[ch].
7224 Added also silc_ske_free_key_material to free the
7225 SilcSKEKeyMaterial structure.
7227 * Defined silc_cipher_set_key function to set the key for
7228 cipher without using the object's method function. The affected
7229 files: lib/silccrypt/silccipher.[ch].
7231 * Implemented silc silc_client_add_private_message_key,
7232 silc_client_add_private_message_key_ske,
7233 silc_client_del_private_message_key,
7234 silc_client_list_private_message_keys and
7235 silc_client_free_private_message_keys functions in the
7238 Added functions silc_client_send_private_message_key to send
7239 the Private Message Key payload and silc_client_private_message_key
7240 to handle incoming Private Message Key payload.
7242 * Added Cipher field to the Private Message Key payload to set
7243 the cipher to be used. If ignored, the default cipher defined
7244 in the SILC protocol (aes-256-cbc) is used.
7246 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7248 * Removed lib/silcclient/ops.h file.
7250 Redefined parts of the SILC Client Library API. Created new
7251 file silcapi.h that deprecates the ops.h file and defines the
7252 published Client Library API. Defined also private message key
7253 API and channel private key API into the file.
7255 This is the file that the application must include from the
7256 SILC Client Library. Other files need not be included by
7257 the application anymore.
7259 * Added new key_agreement client operation callback and also
7260 defined the Key Agreement library API for the application.
7262 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7264 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
7265 is used by clients to request key negotiation between another
7266 client in the SILC network. If the negotiation is started it
7267 is performed using the SKE protocol. The result of the
7268 negotiation, the secret key material, can be used for example
7269 as private message key.
7271 Implemented the Key Agreement payload into the files
7272 lib/silccore/silauth.[ch].
7274 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7276 * Redefined ciphers for the SILC protocol. Added some new ciphers
7277 and defined the key lengths for the algorithms. Changed the
7278 code accordingly. The default key length is now 256 bits.
7280 * Fixed SKE key distribution function silc_ske_process_key_material
7281 when the key length is more than 128 bits. The default key
7282 length in SILC is now 256 bits.
7284 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
7285 to indicate unsupported algorithm.
7287 * Renamed rijndael.c to aes.c and all functions as well.
7289 * Fixed a long standing channel key setting bug in client library.
7290 Weird that it has never surfaced before.
7292 * Fixed bug in channel deletion. If the entire channel is removed
7293 then it must also delete the references of the channel entry
7294 from the client's channel list as the client's channel entry and
7295 the channel's client entry share same memory.
7297 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7299 * Implemented CONNECT and SHUTDOWN commands in the client.
7301 * Implemented CLOSE command to the client.
7303 * Added the function silc_idlist_find_server_by_name into the
7304 files silcd/idlist.[ch].
7306 Added the function silc_idlist_find_server_by_conn into the
7307 files silcd/idlist.[ch].
7309 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7311 * DIE command was renamed to SHUTDOWN. Updated the both code
7314 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
7315 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
7317 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
7320 * Added function silc_server_create_connection function to create
7321 connection to remote router. My server implementation actually
7322 does not allow router to connect to normal server (it expects
7323 that normal server always initiates the connection to the router)
7324 so the CONNECT command is only good for connecting to another
7327 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7329 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
7330 or some other client was kicked from the channel.
7332 Implemented the handling of the notify type to both client
7335 Implemented silc_server_send_notify_kicked to send the KICKED
7336 notify. It is used to send it to the server's primary router.
7338 * Implemented the KICK command into server and client.
7340 * Added `query' argument to the silc_idlist_get_client function
7341 to indicate whether to query the client from server or not if
7344 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
7345 to indicate that the client is not channel founder.
7349 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7351 * Removed the rng context from SilcPacketContext structure and
7352 changed that the packet routine uses the Global RNG API.
7354 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7356 * Added support for quit message that client can "leave" on the
7357 channel when it quits the SILC. It is ditributed inside the
7358 SILC_NOTIFY_TYPE_SIGNOFF notify type.
7360 Added silc_server_free_client_data that will take the
7361 signoff message as argument.
7363 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
7365 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7367 * Updated parts of the protocol specification to keep it up
7370 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7372 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
7373 payloads in one packet.
7375 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
7376 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
7377 use now the new List flag.
7379 * Also deprecated the following packet types: REPLACE_ID,
7380 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
7382 * Added list support for Notify packet in server.
7384 * Added silc_server_send_notify_channel_change to send the
7385 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
7386 the silc_server_send_replace_id.
7388 * Added silc_server_send_notify_nick_change to send the
7389 NICK_CHANGE notify type. Deprecates the function
7390 silc_server_send_replace_id.
7392 * Added silc_server_send_notify_join to send the JOIN notify type.
7393 Deprecates the function silc_server_send_new_channel_user.
7395 * Added silc_server_send_notify_leave to send LEAVE notify type.
7396 Deprecates the function silc_server_send_remove_channel_user.
7398 * Added silc_server_send_notify_cmode and
7399 silc_server_send_notify_cumode to send CMODE and CUMODE notify
7400 types. Deprecates the silc_server_send_set_mode function.
7402 * Added SERVER_SIGNOFF notify type to indicate that server has
7403 quit. This means that all clients on the channel from that
7404 server will drop. This can be also used when netsplit happens.
7406 Deprecated REMOVE_ID packet type since it is not needed anymore
7409 Added silc_server_send_notify_server_signoff to send the
7410 SERVER_SIGNOFF notify type. Deprecates the function
7411 silc_server_send_remove_id.
7413 Added also silc_server_send_notify_signoff to send the
7414 SIGNOFF notify type.
7416 * Employed the PKCS #1. It is the mandatory way to do RSA in the
7417 SILC protocol from this day on. Changed the protocol
7418 specification as well.
7420 * Added silc_server_send_notify_topic_set to send TOPIC_SET
7421 notify type. It is used between routers to notify about
7422 topic changes on a channel.
7424 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
7427 * Partly updated the protocol specification to comply with the
7428 changes now made. It is still though a bit outdated.
7430 * The JOIN notify type now takes one extra argument <Channel ID>.
7431 The packet used to be destined to the channel but now the
7432 JOIN type may be sent as list thus it is impossible to
7433 destine it to any specific channel. By adding this argument
7434 it is again possible.
7436 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7438 * Added CREDITS file. The CHANGES and CREDITS file will appear
7439 in the distribution as well.
7441 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7443 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
7444 types in the server's silcd/packet_receive.c.
7446 * Implemented CMODE and CUMODE to work in router environment.
7448 * Fixed minor encoding and decoding buglet from the
7449 lib/silccore/silcmode.c.
7451 * Fixed buffer overflow from lib/silcclient/command.c in USERS
7454 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
7456 * Changed all SilcConfigServer* and silc_config_server* to
7457 SilcServerConfig* and silc_server_config*, respectively.
7460 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7462 * Associated the ID (client or server ID) to the Authentication
7463 Payload to avoid any possibility of forging. Updated the
7464 protocol specification and the code accordingly.
7466 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7468 * The RSA key length is now save to the RsaKey context in the
7469 key generation process in lib/silccrypt/rsa.c. The key length
7470 is now used to figure out the maximum size of the block allowed
7471 to be encrypted/signed.
7473 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
7474 is equivalent to the silc_mp_mp2bin but does not allocate any
7477 * Changed silc_mp_mp2bin API to take length argument. If it is
7478 non-zero then the buffer is allocated that large. If zero, then
7479 the size is approximated using silc_mp_sizeinbase, which however
7482 * Created Global RNG API which is global RNG that application can
7483 initialize. After initializing, any routine anywhere in the
7484 code (including library) can use RNG without allocating a new
7485 RNG object. This was done to allow this sort of use of the
7486 RNG in code that has no chance to allocate RNG object. All
7487 applications currently allocate this and many routines in the
7488 library use this. Affected file lib/silccrypt/silcrng.[ch].
7490 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
7491 it to use the Global RNG API.
7493 * Defined Authentication Payload into protocol specification that
7494 is used during SILC session to authenticate entities. It is
7495 used for example by client to authenticate itself to the server
7496 to obtain server operator privileges.
7498 Implemented this payload into the lib/silccore/silcauth.[ch].
7499 Implemented also routines for public key based authentication
7500 as the new protocol specification dictates.
7502 Moved definitions of different authentication methods from
7503 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
7505 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
7506 silc_pkcs_verify and silc_pkcs_sign_with_hash and
7507 silc_pkcs_verify_with_hash functions into the file
7508 lib/silccrypt/silcpkcs.[ch].
7510 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7512 * The client entry's userinfo pointer must be always valid.
7513 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
7514 will fail since it requires the userinfo. Now, the userinfo
7515 is allocated as "" if actual userinfo does not exist. Actually,
7516 it must exist and it is totally Ok to drop client connections
7517 that does not announce the userinfo. However, we will make
7518 this workaround for now.
7520 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
7521 to return the remote port by socket.
7523 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7525 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
7526 SILC_SERVER_PENDING_EXEC and added an new macro
7527 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
7528 data or when error occurs while processing the pending command.
7530 Added new argument `destructor' into silc_server_command_pending
7531 and to the SilcServerCommandPending object. This destructor is
7532 now called after calling the pending callback or if error occurs
7533 immediately. If error occurs the actual pending callback won't
7534 be called at all - only the destructor. The destructor may be
7535 NULL if destructor is not needed.
7537 All this applies for client library code as well. Similar
7538 changes were made there as well for the pending commands.
7540 In the client, the application must now allocate the
7541 SilcClientCommandContext with the silc_client_command_alloc
7544 * Added reference counter to the SilcServerCommandContext. Added
7545 function silc_server_command_alloc and silc_server_command_dup
7548 Same type of functions added to the client library for the same
7551 * Removed the cmd_ident from IDListData away since it is now
7552 global for all connections. It is the command identifier used
7553 in command sending and with pending commands. The affected file
7556 * Added reference counter to the SilcSocketConnection objecet to
7557 indicate the usage count of the object. The object won't be
7558 freed untill the reference counter hits zero. Currently only
7559 server uses this, and client ignores it. The client must be
7560 set to use this too later. The affected files are
7561 lib/silccore/silcsockconn.[ch]. Added also the function
7562 silc_socket_dup to increase the reference counter.
7564 This was mainly added because it is possible that the socket
7565 is removed underneath of pending command or other async
7566 operation. Now it won't be free'd and proper DISCONNECTING
7567 flags, etc. can be set to avoid sending data to connection that
7568 is not valid anymore.
7570 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
7571 the connection. After that it sets SILC_SET_DISCONNECTED.
7572 It is, however, possible that the socket data is not still freed.
7573 The silc_server_packet_process now checks that data is not
7574 read or written to connection that is DISCONNECTED. The socket
7575 get's freed when the reference counter hits zero.
7577 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7579 * Changed the client operation API: channel_message operation's
7580 `sender' is now the client entry of the sender, not the nickname
7581 and the `channel' is the channel entry, not the channel name.
7583 In the private_message operation the `sender' is now also the
7584 client entry of the sender not the nickname.
7586 Affected file is lib/silcclient/ops.h and all applications
7587 using the client operations.
7589 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7591 * Moved the calling of ops->connect() from connect_to_server_final
7592 into receive_new_id functin since that is the point when the
7593 client is actually allowed to send traffic to network. The
7594 affected file is lib/silcclient/client.c.
7596 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7598 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
7599 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
7600 (if needs broadcasting) instead of broadcasting the packets one
7601 by one which would make a burst in the network traffic.
7603 * Added `broadcast' argument to the functions in silcd/server.[ch]
7604 silc_server_create_new_channel[_with_id] to indicate whether
7605 to send New Channel packet to primary router.
7607 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7609 * Added new function into the silcd/server.[ch] files:
7610 silc_server_create_new_channel_with_id to create new channel with
7611 already existing Channel ID.
7613 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
7614 lib/silccore/silcpacket.h. This packet is used t send list of
7615 Set Mode payloads inside one packet. Server uses this to set
7616 the modes for the channels and clients on those channels, that it
7617 announced to the router when it connected to it. The protocol
7618 specification has been updated accordingly.
7620 * The silc_server_new_channel did not handle the packet coming
7621 from normal server as it normally does not send that. However,
7622 when it announces its channels it does send it. Implemented
7623 the support for that.
7625 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
7626 into the file lib/silccore/id.h.
7628 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7630 * Fixed memory leaks in the functions silc_idlist_del_client,
7631 silc_idlist_del_channel and silc_idlist_del_server in the file
7632 silcd/idlist.c. All of those leaked like a sieve.
7634 * Fixed some small memory leaks in the client's function
7635 silc_client_notify_by_server.
7637 * Added functions into silcd/server.c: silc_server_announce_clients,
7638 silc_server_announce_channels and silc_server_announce_server.
7639 These functions are used by normal and router server to announce
7640 to its primary router about clients, channels and servers (when
7641 router) that we own. This is done after we've connected to the
7644 These functions effectively implements the following packet types:
7645 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
7646 and SILC_PACKET_NEW_ID_LIST.
7648 * Added new functions into the silcd/packet_receive.[ch]:
7649 silc_server_new_id_list, silc_server_new_channel_list and
7650 silc_server_new_channel_user_list to handle the incoming
7651 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
7653 * Added support of changing Channel ID in the function
7654 silc_server_replace_id. If the server that announces a channel
7655 to the router already exists in the router (with same name but
7656 with different Channel ID), router is responsible to send
7657 Replace ID packet to the server and force the server to change
7658 the Channel ID to the one router has.
7660 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
7661 client that the Channel ID has been changed by the router. The
7662 normal server sends this to the client. Client must start using
7663 the new Channel ID as the channel's ID.
7665 Implemented handling of this new type into lib/silcclient/client.c
7666 into the function silc_client_notify_by_server.
7668 * Added new function silc_idlist_replace_channel_id into the files
7669 silcd/idlist.[ch] to replace the Channel ID.
7671 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7673 * Call silc_server_command_identify_check always when processing
7674 the IDENTIFY command in silcd/command.c
7676 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7678 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
7679 send keepalive packets. The packet can be sent by clients,
7680 servers and routers.
7682 Added function silc_socket_set_heartbeat into the file
7683 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
7684 If not set, the heartbeat is not performed. The actual
7685 heartbeat is implemented in the low level socket connection
7686 library. However, application is responsible of actually
7689 Added silc_server_send_heartbeat to send the actual heartbeat
7690 packet into silcd/packet_send.[ch]. Server now performs
7691 keepalive with all connections.
7693 * Added silc_task_get_first function into lib/silcutil/silctask.c
7694 to return the timeout task with shortest timeout. There was a bug
7695 in task unregistration that caused problems. TODO has been
7696 updated to include that task system must be rewritten.
7698 * The client library will now resolve the client information when
7699 receiving JOIN notify from server for client that we know but
7700 have incomplete information.
7702 * Rewrote parts of silc_server_remove_from_channels and
7703 silc_server_remove_from_one_channel as they did not remove the
7704 channel in some circumstances even though they should've.
7706 * Encryption problem encountered in server:
7708 The LEAVE command used to send the Channel Key packet to the
7709 router immediately after generating it. However, the code
7710 had earlier sent Remove Channel user packet but not immediately,
7711 ie. it was put to queue. The order of packets in the router
7712 was that Channel Key packet was first and Remove Channel User
7713 packet was second, even though they were encrypted in the
7714 reverse order. For this reason, MAC check failed. Now, this
7715 is fixed by not sending the Channel Key packet immediately but
7716 putting it to queue. However, this is more fundamental problem:
7717 packets that are in queue should actually not be encrypted
7718 because packets that are sent immediately gets encrypted
7719 actually with wrong IV (and thus MAC check fails). So, packets
7720 that are in queue should be encrypted when they are sent to
7721 the wire and not when they put to the queue.
7723 However, the problem is that the current system has not been
7724 designed to work that way. Instead, the packet is encrypted
7725 as soon as possible and left to the queue. The queue is then
7726 just purged into wire. There won't be any fixes for this
7727 any time soon. So, the current semantic for packet sending
7730 o If you send packet to remote host and do not force the send
7731 (the packet will be in queue) then all subsequent packets to the
7732 same remote host must also be put to the queue. Only after the
7733 queue has been purged is it safe again to force the packet
7736 o If you send all packets immediately then it safe to send
7737 any of subsequent packets through the queue, however, after
7738 the first packet is put to queue then any subsequent packets
7739 must also be put to the queue.
7741 Follow these rules and everything works fine.
7743 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7745 * Added new function silc_server_remove_clients_by_server to
7746 remove all client entries from ID list when the server connection
7747 is lost. In this case it is also important to invalidate all
7748 client entires as they hold the invalid server entry. This
7749 fixes fatal bug when server has lost connection and will reconnect
7752 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7754 * Made some sanity checks to silc_server_daemonise like to check
7755 whether the requested user and group actually exists.
7757 * Added sanity check to SKE's silc_ske_responder_finish to check
7758 that the public and private key actually is valid.
7760 * Invalidate the client's nickname when receiving Replace ID
7761 packet and the Client ID is being replaced. This means that the
7762 server will query the nickname if someone needs it (client)
7765 * Sort the ID Cache in client library when the ID Cache data
7766 has changed (needs sorting).
7768 * Do not allow for SILC client to create several connections to
7769 several servers. The client does not support windows right now
7770 and generating multiple connections causes weird behaviour.
7772 Irssi-silc client does support windows and can handle several
7773 connections without problems, see: www.irssi.org and SILC plugin.
7775 * Fixed some places where client was added to the IDList. The
7776 rule of thumb is following (in order to get everything right):
7777 If the client is directly connected local client then the
7778 `connection' argument must be set and `router' argument must be
7779 NULL to silc_idlist_add_client function. If the client is not
7780 directly connected client then the `router' argument must
7781 bet set and the `connection' argument must be NULL to the
7782 silc_idlist_add_client function.
7784 * The funtion silc_server_packet_send_local_channel actually did
7785 not check whether the client was locally connected or not. It
7786 does that now. Fixed a bug related to LEAVE command.
7788 * Fixed Remove Channel User payload parsing bug in server's
7789 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
7791 * The server's silc_server_save_channel_key now checks also the
7792 global ID list for the channel as it might not be in the local
7793 list. Fixed a bug related to LEAVE command.
7795 * Is this the end of the [<unknown>] buglet that has been lurking
7796 around for a long time? A little for loop fix in server's
7797 silc_server_command_whois_parse that is used by both IDENTIFY
7798 and WHOIS command. At least, this was a clear bug and a cause
7799 of one type of [<unknown>] buglet.
7801 * WHOIS and IDENTIFY commands call the function
7802 silc_server_command_[whois/identify]_check function even if
7803 we are not router server.
7805 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7807 * Added --with-gmp configuration option. If set the GMP
7808 is always compiled in the SILC source tree. If not set then
7809 it is checked whether the system has the GMP3 installed. If
7810 it has then the GMP won't be compiled (the system's headers
7811 and library is used), if it doesn't have it then the GMP is
7812 compiled in the SILC source tree.
7814 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7816 * Changed RSA private exponent generation to what PKCS #1
7817 suggests. We try to find the smallest possible d by doing
7818 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
7819 not security fix but optimization.
7821 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7823 * Added new config entry [Identity] to fork the server and run
7824 it as specific user and group. A patch from Bostik.
7826 * Imported Dotconf configuration library into lib/dotconf.
7827 This will be used to create the SILC configuration files later.
7828 It will appear in the distsribution after this commit.
7830 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7832 * A big code auditing weekend happening. Auditing code for
7833 obvious mistakes, bugs and errors. Also, removing any code
7836 Removed files for being obsolete:
7838 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
7839 inline in the file lib/silcutil/silcbuffer.h)
7841 o lib/silcutil/silcbufutil.c (the header has inline versions)
7843 Changed code to fix possible error conditions:
7845 o The buffer formatting routines now check that the destination
7846 buffer really has enough space to add the data. This applies for
7847 both buffer formatting and unformatting
7848 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
7849 unformatting was changed to accomodate following rules:
7850 XXX_*STRING_ALLOC will allocate space for the data into the pointer
7851 sent to the function while XXX_*STRING will not allocate or copy
7852 the data into the buffer. Instead it sets the pointer from the
7853 buffer into the pointer sent as argument (XXX_*STRING used to
7854 require that the pointer must be allocated already). This change
7855 makes this whole thing a bit more consistent and more optimized
7856 (note that the data returned in the unformatting with XXX_*STRING
7857 must not be freed now). The routines return now -1 on error.
7859 o Tried to find all code that use buffer_format and buffer_unformat
7860 and added return value checking to prevent formatting and
7861 especially unformatting errors and possible subsequent fatal
7864 o Changed ske->x and ske->KEY to mallocated pointers in
7865 lib/silcske/silcske.h. Fixed possible data and memory leak.
7867 o Added return value checking to all *_parse* functions. Fixed
7868 many memory leaks as well.
7870 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
7871 so that buffer overflows would not happen. All code now also
7872 checks the return value as it can fail.
7874 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7876 * Added reconnection support to server if the normal server looses
7877 its connection to the router (for example if router is rebooted).
7878 The server performs normal reconnection strategy implemented
7879 to the server. Affected file silcd/server.c.
7881 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7883 * Added new packet type SILC_PACKET_SET_MODE that is used to
7884 distribute the information about changed modes (for clients,
7885 channels and clients channel modes) to all routers in the
7886 network. Updated the protocol specification accordingly.
7888 Added functions into silcd/packet_send.c and
7889 silcd/packet_receive.c: silc_server_send_set_mode,
7890 silc_server_set_mode.
7892 Added new files silcmode.[ch] into lib/silccore that implements
7893 the encoding and decoding of Set Mode Payload. Added new type
7894 SilcSetModePayload. Moved the definitions of different modes
7895 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
7897 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7899 * Oops, a little mistake in server's connection authentication
7900 protocol. The protocol is not ended with FAILURE but with
7901 SUCCESS if the authentication is Ok. :) Affected file is
7904 * Implemented NICK_CHANGE notify handling in server in the file
7905 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
7906 the local clients on the channel. After the changing nickname
7907 in router environment snhould work and the [<unknown>] nickname
7908 should appear no more.
7910 The silc_server_replace_id function that receives the Replace ID
7911 payload now sends the NICK_CHANGE notify type also in the file
7912 silcd/packet_receive.c
7914 * Changed WHOIS and IDENTIFY command to support the maximum amount
7915 of arguments defined in protocol specs (3328 arguments). This
7916 fixed a bug that caused problems when there were more than three
7919 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7921 * Added extra parameter, command identifier, to the
7922 silc_client_send_command so that explicit command identifier
7925 Changed that ID list routines uses specific command identifier
7926 when sending WHOIS/IDENTIFY requests to the server so that they
7927 can be identified when the reply comes back.
7929 Affected files lib/silcclient/command.[ch],
7930 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
7932 * Added `sender' argument to silc_server_packet_send_to_channel
7933 to indicaet the sender who originally sent the packet to us
7934 that we are now re-sending. Ignored if NULL. Affected file
7935 silcd/packet_send.[ch].
7937 * Added some server statistics support in silcd/server_internal.h
7938 SilcServerStatistics structure and around the server code. Also
7939 send some nice statistics information when client is connecting
7942 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7944 * Fixed channel ID decoding in server's JOIN command reply in
7945 silcd/command_reply.c
7947 * Fixed braodcasting of replace ID payload to not to send it if
7948 we are standalone server in silcd/packet_receive.c.
7950 * Fixed all channel message sending routines to not to send
7951 packets to clients that has router set, since they are routed
7952 separately in the same function earlier. Affects file
7953 silcd/packet_send.c and all channel packet sending functions.
7955 * In USERS reply, res_argv[i] are not allocated, the table
7956 is allocated. Thus changed that free the table, not its
7959 * In server's whois_check and identify_check if the client is
7960 locally connected do not send any WHOIS commands - they are not
7963 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7965 * Fixed some minor bugs in client when sending WHOIS command. The
7966 arguments was in wrong order.
7968 * Removed statis function add_to_channel from server in
7969 silcd/command.c that was previously used with the joining but
7972 * Tested USERS command in router environment successfully with two
7973 routers, two servers and two clients.
7975 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7977 * Reorganized the USERS command and command reply in client library
7978 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7979 When the command is given by user we register a pending command
7980 callback that will reprocess the command after the reply has been
7981 received from the server. When reprocessing the packet we then
7982 display the information. Thus, the USERS information is displayed
7983 now in the command callback instead of in the command reply
7984 callback. The processing of the command is same as previously
7985 when server has sent the command reply in the JOINing process.
7987 * Added to USERS command in silcd/command_reply.c to join the client,
7988 we didn't use to know about, to the channel after we've created
7989 a client entry for it. Also, for clienet we did know already still
7990 check whether it is on the channel or not and add it if not.
7992 * Removed silc_server_command_join_notify as the function and its
7995 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7997 * Changed the client's pending command handling to the same as the
7998 server's pending command handling. It is also now possible to
7999 execute command reply functions from other command reply
8000 function as the function callbacks for commands and command
8001 replies are one and same. The pending commands are not static
8002 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
8003 in client connection context. Thus, pending commands are server
8004 connection specific as it is convenient.
8006 Changed the function silc_client_command_pending and
8007 silc_client_command_pending_del and added new function
8008 silc_client_command_pending_check. Removed the
8009 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
8012 * Added cmd_ident, current command identifier, to the client
8013 connection context in lib/silcclient/client.h to keep track on
8014 command identifiers used in command sending. Client's command reply
8015 function handling now supports the mandatory command identifiers.
8017 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
8018 funtions in client to fully support pending command callbacks.
8020 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
8021 as one of the arguments to the application in the command reply
8024 * NOTE: The FORWARDED flag is depracated. It used to be depracated
8025 before first releasing SILC but came back. Now it is removed again
8026 and should come back nomore. The FORWARDED flag was used only
8027 by the JOINing procedure by forwarding the command packet to router.
8028 Now, the JOINing procedure has been changed to more generic (due
8029 to various router environment issues) and FORWARDED is not needed
8030 anymore for anything. The protocol specification is yet to be
8033 Now, removed silc_server_packet_forward from server and the flag
8034 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
8036 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8038 * Renamed NAMES command to USERS command. The NAMES was named that
8039 due to historical reasons. Now it is renamed. Also, rewrote
8040 parts of the USERS command. The nickname list is not sent anymore
8041 by the server. Only Client ID and mode lists are sent in the USERS
8042 command. Changed this also to the protocol specification.
8044 The client now resolves the names and stuff after it receives
8045 the USERS list from the server when joining to the channel.
8047 * WHOIS and IDENTIFY commands has been changed to support multiple
8048 Client ID's per command. One can now search for multiple users
8049 in the network by sending only one WHOIS or IDENTIFY command.
8050 Changed the code and the protocol specifications.
8052 * Removed silc_server_command_identify_parse and changed that IDENTIFY
8053 uses silc_server_command_whois_parse to parse the request. */
8055 * If normal server, do not parse the WHOIS and IDENTIFY requests
8056 before sending it to the router. Saves some time.
8058 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8060 * Fixed JOIN command on client library. Wrong number of arguments
8061 used to crash the client.
8063 * Added silc_server_channel_has_global function to check whether
8064 channel has global users or not.
8066 * Added silc_server_channel_has_local function to check whether channel
8067 has locally connected clients on the channel.
8069 * The silc_server_remove_from_one_channel now checks whether the
8070 channel has global users or not after given client was removed from
8071 the channel. It also checks whether the channel has local clients
8072 on the channel anymore. If it does not have then the channel entry
8073 is removed as it is not needed anymore.
8075 * The silc_server_notify now checks on JOIN notify whether the joining
8076 client is one of locally connected or global. If it is global then
8077 the channel has now global users on the channel and that is marked
8078 to the channel entry. Also, it now saves the global client to
8079 global list who is joining and JOINs it to the channel. This is
8080 for normal server, that is.
8082 Changed silc_server_send_notify_on_channel,
8083 silc_server_packet_relay_to_channel and
8084 silc_server_packet_send_to_channel check if we are normal server
8085 and client has router set (ie. global client) do not send the
8086 message to that client, as it is already routed to our router.
8088 * Implemented LEAVE notify type handling in silc_server_notify
8091 * Tested LEAVE command in router environment successfully. Tested
8092 with two routers, two servers and two clients.
8096 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
8098 * Implemented SIGNOFF notify type handling in silc_server_notify
8101 * silc_server_remove_id now removes the client entry from all channels
8102 it has joined and thusly sends SIGNOFF notify type.
8104 * Rewrote the NAMES list generation in server by removing two excess
8105 loops. The lists are created now inside one loop.
8107 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8109 * silc_server_remove_channel_user checks now also global list
8110 for channel and client.
8112 * silc_server_new_channel_user checks now both local and global
8113 list for channel and client. Fixed a bug in client id decoding.
8114 Used to decode wrong buffer.
8116 * silc_server_channel_message checks now both local and global
8117 list for channel entry.
8119 * Tested channel joining (hence JOIN) in router environment
8120 successfully. Tested with two routers, two servers and two
8123 * Tested channel message sending in router environment successfully.
8125 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8127 * Added silc_server_save_channel_key into server.[ch] to save the
8128 received channel key in Channel Key payload processing. It is
8129 also used in JOIN command reply handling.
8131 Equivalent function silc_client_save_channel_key added into
8132 client.[ch] into client library.
8134 * Changed JOIN command reply to send information whether the channel
8135 was created or not (is existing already) and the channel key
8136 payload. Changed protocol specs accordingly.
8138 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
8139 the request was sent by ID and not by nickname. Crashed on
8142 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8144 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
8145 now correctly save the received data.
8147 * silc_server_free_sock_user_data now notifies routers in the
8148 network about entities leaving the network.
8150 At the same time implemented functions silc_server_remove_id
8151 and silc_server_send_remove_id to receive and send REMOVE_ID
8152 packets. The packet is used to notify routers in the network
8153 about leaving entities. The ID removed will become invalid in
8156 * Added function silc_idlist_del_server into server. Removes and
8157 free's server entry from ID list.
8159 * silc_server_private_message function now checks, if we are router,
8160 that the destination ID really is valid ID, naturally.
8162 * In router when NEW_ID packet is received (for new client) the
8163 hash of the Client ID is saved in the ID Cache but the
8164 client->nickname is set to NULL, instead of putting the hash
8167 IDENTIFY command now also checks that client->nickname must be
8168 valid. If it is not if will request the data from the server who
8169 owns the client. Added new function
8170 silc_server_command_identify_check.
8172 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
8173 to set the command to already allocated Command Payload.
8175 * Tested private message sending in router environment with two
8176 routers, two servers and two clients. Fixed minor bugs and now
8179 * Fixed segfault from client's NAMES command. Used to crash if
8182 * Forwarded packets must not be routed even if it is not destined
8183 to the receiver. Changed server code comply with this.
8185 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8187 * Added `require_reverse_mapping' boolean value to ServerParams
8188 structure. If TRUE (not default) the server will require that
8189 the connecting host has fully qualified domain name.
8191 If the reverse mapping is not required and hostname could not be
8192 found the IP address is used as hostname.
8194 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8196 * Implemented version string checking to both client and server.
8197 The check is incomplete currently due to the abnormal version
8198 strings used in development version of SILC.
8200 * Changed all command functions in server to use the new
8203 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8205 * Changed char *data to unsigned char *data in ID Cache system to
8206 support binary data as ID Cache data. Changed code to support
8207 binary data in lib/silccore/idcache.c.
8209 * Renamed silc_server_packet_relay_command_reply to
8210 silc_server_command_reply as it is normal packet receiving
8211 function. Rewrote the function to accept command replys for
8212 servers and not only for clients.
8214 * Mark remote router always as registered server if we are connecting
8215 to it. Otherwise, commands sent by the router to us are ignored.
8217 * All ID List find routines now returns the ID Cache Entry pointer
8218 as well if requested.
8220 * WHOIS command works now in router environment, tested with two
8221 routers, two servers and two clients.
8223 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
8224 in router environment (as it is almost equivalent to WHOIS) but
8225 hasn't been tested thoroughly. Added new functions:
8227 silc_server_command_identify_parse
8228 silc_server_command_identify_send_reply
8229 silc_server_command_identify_from_client
8230 silc_server_command_identify_from_server
8232 * Disabled route cache adding because adding two different ID's with
8233 same IP replaces the old cache entry thus giving wrong route.
8234 The entry->router->connection is always the fastest route anyway
8235 so route cache may not be needed. Of course, new routes maybe
8236 established after receiving the ID when the entry->router->connection
8237 might not be anymore the most optimal.
8239 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8241 * Add route cache for received ID for fast routing.
8243 * Added silc_server_packet_route to route received packet on router
8244 that is not destined to us.
8246 * Renamed silc_server_get_route to silc_server_route_get.
8248 * Added id_string and id_string_len fields into SilcServer to
8249 include encoded ServerID for fast comparing without excess
8250 encoding of the ID's.
8252 * Cleaned up WHOIS command on server side. Added following static
8255 silc_server_command_whois_parse
8256 silc_server_command_whois_check
8257 silc_server_command_whois_send_reply
8258 silc_server_command_whois_from_client
8259 silc_server_command_whois_from_server
8261 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
8262 arguments in command replies. All command functions should be
8263 updated to use this macro.
8265 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8267 * Minor typo fixes on command reply handling on server.
8269 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8271 * Added silc_server_command_add_to_channel internal routine to add
8272 the client to the channel after router has created the channel and
8273 sent command reply to the server.
8275 * Added generic silc_server_send_command to send any command from
8278 * Use static buffer with ID rendering instead of duplicating data.
8280 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8282 * Fixed a channel user mode bug when joining to a channel server gave
8283 everybody channel founder rights, oops.
8285 * We mark ourselves as the router of the incoming server connection
8286 if we are router ourselves. This way we can check in some packet
8287 sending functions whether it is locally connected server. For
8288 incoming router connections we put NULL.
8290 * For router sending packets locally means now always sending the
8291 packet cell wide; to local clients and local servers. For normal
8292 server sending packet locally means sending it to only local
8295 * Fixed the JOIN command to really work in router environment. If the
8296 channel is created it is always created by the router. Router is
8297 also responsible of making the initial joining to the channel,
8298 sending JOIN notify to the sending server and distributing
8299 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
8300 does not exist server doesn't do anything else but forward the
8301 command to the router which performs everything.
8303 * Added silc_server_send_channel_key function to send the Channel Key
8306 * Added silc_server_create_channel_key to create new channel key. The
8307 channel key is now re-generated everytime someone joins or leaves
8308 a channel, as protocol dictates. Note: channel->key_len is the
8311 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8313 * Splitted server.[ch] finally. Created now packet_send.[ch] and
8314 packet_receive.[ch] to separate packet sending and receiving
8315 routines. The server.[ch] now includes everything else including
8316 actual packet processing (writing and reading data) and other
8319 Renamed silc_server_private_message_send_internal to
8320 silc_server_send_private_message. The routine is still though
8321 used only to relay private messages as server does not send
8322 private messages itself.
8324 Renamed silc_server_new_channel to silc_server_create_new_channel
8325 and added new function sicl_server_new_channel that handles the
8326 incoming New Channel packet. Added also new sending function
8327 silc_server_send_new_channel to send New Channel Payload.
8329 * Added new function silc_server_notify to process incoming notify
8330 packet to the server/router. Server may then relay the notify
8331 to clients if needed.
8333 * Added new function silc_server_new_channel_user to process incoming
8334 New Channel User packet. Router will redistribute the packet and
8335 send JOIN notify to its local clients and locally connected servers
8336 if needed. Normal server will send JOIN notify to its local client
8337 on same channel when received this packet. Added also corresponding
8338 sending function silc_server_send_new_channel_user to sent the
8341 * Added boolean route argument to send_notif_to_channel and
8342 packet_send_to_channel functions to attempt to route the packet
8343 if it is TRUE and send only locally if it is FALSE.
8345 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8347 * silc_server_replace_id now broadcasts the received replace ID
8348 packet if it is not broadcast packet already. The router must
8349 broadcast to inform other routers about changed ID.
8351 * Added backpointer to server's router into SilcServer context in
8352 silcd/server_internal.h.
8354 * Fixed silc_server_packet_broadcast to send correct broadcast
8357 * The channel key is now distributed to the local client as soon
8358 as it is received from the router (in router environment) so that
8359 no other packet may be sent for the channel until client has
8362 * silc_server_remove_channel_user now broadcasts the received
8363 Remove Channel User packet if it is not broadcast packet already.
8364 The router must broadcast to inform other routers about removed
8367 * Added users field into SilcPacketContext that is a reference count
8368 of the context. One can increase the reference count by calling
8369 silc_packet_context_dup which is now changed to just increase the
8370 reference count instead of duplicating the data. The reference
8371 count is decresed by calling silc_packet_context_free that will
8372 free the data after the reference count hits zero.
8374 For now on the packet context and everything allocated into it
8375 (including the raw packet from network) must be freed by calling
8376 the new silc_packet_context_free function. Added also new function
8377 silc_packet_context_alloc that must be used now to allocate the
8378 context. This also means that if a routine is asynchronous from
8379 silc_[client/server]_packet_parse_type the packet context must
8380 be duplicated by calling silc_packet_context_dup. Otherwise it
8381 gets free'd after silc_[client/server]_packet_parse_type returns.
8382 Also, one must remember that if packet is duplicated then its
8383 reference count must be decresed by calling the free function as
8384 many times as it was duplicated.
8386 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
8387 from both client and server.
8389 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8391 * Made joining to a channel working in router environment.
8393 * Cleaned up JOIN command on server side and create function
8394 silc_server_command_join_channel internal routine to make the
8397 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8399 * Changed silc_command_pending list to SilcDList. Also, added
8400 `ident' field to SilcServerCommandPending structure to identify
8401 the reply and to call correct callback.
8403 Added silc_server_command_pending_check function to replace the
8404 corresnponding macro. The silc_command_pending list is not
8407 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
8408 to set identifier to previously allocated Command Payload. It
8409 is used to set identifier for command when resending Command
8412 * Added silc_command_payload_encode_payload to encode Command
8413 Payload buffer from SilcCommandPayload structure.
8415 * Added silc_argument_payload_encode_payload to encode Argument
8416 payload buffer from SilcArgumentPayload structure.
8418 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8420 * Changed WHOIS command to support router connection on server side.
8421 The whois request is always sent to router unless the server is
8422 standalone server. After server has received the reply from the
8423 router will it send the reply to the client.
8425 * Added silc_server_packet_broadcast into silcd/server.[ch] to
8426 broadcast received broadcast packet. The function is used only
8427 by router. The broadcast packet is always sent to the router's
8430 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
8431 render given ID to printable string, for log files for example.
8433 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8435 * Made basic router to router connections working. At least they
8436 can now connect to each other but nothing really works the way
8437 they are supposed - yet.
8439 * Added new initiator token to RouterConnection configuration
8440 file in silcd/serverconfig.[ch]. It is used to tell whether we
8441 are the initiator to the remote router or whether we'll expect
8442 the other end to connect.
8444 * Moved registering of listener task to silc_server_init, hence
8445 the server starts listenning as soon as it is run, even if it
8446 does not have connections to other routers. Let's see how well
8449 * Changed default connection retry timeouts for more suitable in
8452 * Removed cipher and such arguments from silc_idlist_add_client
8453 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
8454 Added new function silc_idlist_add_data to add the keys and stuff
8457 * Added SilcIDListData structure and added it to SilcClientEntry
8458 and SilcServerEntry as their first field in the structure. This
8459 way we can explicitly cast the ID entries to the SilcIDListData
8460 structure and get common data for the entries. In past, we had
8461 to first check what type of connection it is and then cast it to
8462 correct ID entry type. Now, we can directly cast the opaque
8463 pointer to the SilcIDListData (no matter what ID entry it actually
8464 is) and get the data needed.
8466 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8468 * Wow, found a bug in scheduler. The scheduler uninitialized itself
8469 in some circumstances even if threre were timeout tasks, though not
8470 IO tasks, but tasks anyway. Now fixed.
8472 * Defined SilcServerConnection structure to hold connection specific
8473 stuff about directly connected servers and routers. The definition
8474 is currently in silcd/server_internal.h. I thought about having
8475 a bit more important role fro this struct but for now it is used
8476 only when connecting to other server (or router actually).
8478 * Added connecting retry support in server when connecting to
8479 router(s). The retry feature implement exponential backoff
8480 algorithm. Also, added SilcServerParams structure to hold default
8481 parameters for server. For now, it include these retry settings
8482 and are hard coded. After server is moded to be as Silc Server
8483 Library this structure will be more important.
8485 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8487 * Changed client librarys channel->clients table to SilcList and
8488 changed code accordingly.
8490 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8492 * Changed client's channel table to SilcList and changed code
8493 accordingly. Also changed SilcChannelClientEntry to include back-
8494 pointer to the channel so that client entry can use that structure
8495 as list as well and we have fast cross-reference to the channel.
8496 This change dramatically decreased the complexity of channel
8497 handling with client entry and vice versa (removed one extra
8498 loop when searching for channel entry from many functions).
8500 * Changed server->sim from table to SilcDList and changed code
8503 * NAMES command can now be used from user interface. It will show
8504 the user list on the channel, neatly.
8506 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
8507 Code now saves realname of the user if it becomes available.
8509 * Renamed configure.in to configure.in.pre and made ./prepare
8510 script to automatically add correct version string to
8511 configure.in which it creates from configure.in.pre.
8513 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8515 * NAMES command reply now shows users mode with the nickname when
8518 * Moved silc_client_ch[u]mode[_char] functions from
8519 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
8520 place sucks, they are utility functions and should be in some
8523 * Fixed some unsigned int's to unsigned short's. Patch by cras.
8525 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
8528 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8532 * Added TRQ (efficient deque and list library) into lib/trq. This is
8533 a very good list library that is currently used in the SILC. Defined
8534 SilcList API over the library because I didn't like the API very
8535 much. See lib/trq/silclist.h for the API and examples of how to
8536 use the API. Fixed various places in the code to use the new
8537 SilcList API. The SilcList is meant for lists that has a structure
8538 already defined as a list. It is not suitable to add just some
8539 context to the list (in TRQ, the context is the list actually).
8541 So, I defined SilcDList that can be used for the purpose where
8542 predefined list structure does not exit. This can be used as
8543 such list. Now some context just can be added to the SilcDList.
8544 Currently this list is not used in the SILC just yet, though there
8545 are a lot places where this can replace dynamically allocated
8546 tables and I will fix these places, later, to use SilcDList.
8547 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
8548 and use TRQ internally).
8550 Also fixed some annoying warning messages that the original TRQ
8551 code generated. Also minor changes to TRQ's Makefile.in.
8553 * Added support for querying by Client ID to both WHOIS and
8554 IDENTIFY commands into server, as required by the protocol.
8556 * Removed method function pointers from SilcBuffer structure. They
8557 weren't used to anything and just increased the context size for
8558 no good reason. This change also made silc_buffer_alloc and
8559 silc_buffer_free functions inline functions.
8561 * Disabled command flooding detection support until it's fixed so
8562 that it accepts commands in but does not execute them more than once
8565 * Added silc_net_localhost(), to return local hostname, into
8566 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
8567 that must be initialized before calling silc_client_init.
8569 * Added new function: silc_server_send_notify_on_channels to send
8570 notify messages to all channels client has joined. It is assured
8571 that the message is sent only once per client.
8573 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
8574 lib/silcutil/silcutil.[ch] as silc_format function. The new
8575 function is generic and is used by server as well, not only by
8576 the logging routines.
8578 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
8579 the provided version string was not acceptable. Added new function:
8580 silc_ske_check_version into lib/silcske/silcske.h. The function
8581 must be implemented by the application (client or server) and it
8582 does not reside in the SKE library. The function checks the version
8583 string remote end sent.
8585 * Added back pointers (to opaque context and to SilcSocketConnection)
8586 into SilcPacketContext structure into lib/silccore/silcpacket.h.
8588 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
8589 duplicate packet context structure.
8591 * Changed `notify' client operation to send same arguments as client
8592 receives from server except for ID's. ID's are mapped to correct
8593 ID entry and that is returned. Also, if channel entry is not sent
8594 by server but the notify is for channel the channel entry is sent
8595 to application (otherwise application doesn't know that it is for
8596 channel (library gets it from packet's Destination ID)).
8598 * Added silc_client_remove_from_channels into client library to
8599 remove a client from all channels it has joined to. Used when
8600 received SIGNOFF notify from server. Added also new function
8601 silc_client_replace_from_channels to replace old ID entry with
8602 new ID entry on all channels. Used when received NICK_CHANGE
8605 * Fixed ID Cache list handling in silc_idlist_get_client in
8606 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
8607 to get (or query) client by ID.
8609 * Updated TODO list.
8611 * Added connection authentication status message defined by the
8612 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
8613 support for these into the code in client and server side.
8615 * Added generic function silc_client_send_command to send any command
8616 with variable argument list. Application should use this function
8617 to send commands if the command functions provided by the library
8618 does not suite for the application's user interface needs.
8620 * Added new `failure' client operation. Application is notified about
8621 received failure packet if client is executing a protocol. In this
8622 case the protocol's execution has failed.
8624 * Added SKE's end notify to send the SKE_SUCCESS notify message that
8625 is required by the protocol.
8627 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
8628 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
8631 * Added status flag to SilcSKE object to indicate realtime status
8632 of the SKE protocol.
8634 * Application receives now exactly same command reply arguments as
8635 the library receives from server. However, if ID is received the
8636 corresponding ID entry is returned to the application (eg. Client
8637 ID is mapped to correct SilcClientEntry entry and that is returned).
8638 Changed command_reply client operation due to this change.
8640 * Changed all ID's in commands and in command replys as ID Payloads.
8641 Change affected both client and server side codes.
8643 All ID's sent in SILC network (with execption of ID's in SILC
8644 Packet header) are sent in ID Payload to support variable length
8647 * Server now notifies nick changes and notifies all clients on
8648 the channels about the new nickname (about the new Client ID,
8651 * Implemented CMODE command to change channel modes. Supports all
8652 channel modes defined by the protocol specs except ban and invite
8653 lists. (Also, private channel key mode is supported but support for
8654 setting private channel key in client is missing, thus, this mode
8655 has no effect on client side (except that server requires that the
8656 client uses private channel key and normal channel traffic does not
8659 Also, invite mode works per se, but INVITE command does not work
8660 yet correctly, so you can set channel as invite only channel but
8661 inviting clients to the channel does not work (it is yet to be
8662 thought what's the best way to do it).
8664 * Added new command SILC_COMMAND_CUMODE to change user mode on the
8665 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
8666 Implemented CUMODE command to change user's mode on the channel.
8667 Supports all modes defined by the protocol specs.
8669 * Added NAMES command reply to return users modes on the channel.
8671 * Removed unnecessary and slow ciphers from lib/silccrypt.
8673 * Set SO_KEEPALIVE option to connection sockets by default.
8675 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
8677 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
8678 redefined the Notify Payload into protocol specs.
8680 * Added silc_id_payload_parse_id to get ID directly from raw
8683 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8685 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
8686 accept searching by Client ID as well.
8688 * Added support for LEAVE and SIGNOFF notify types in client library.
8690 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
8691 to parse ID Payload from raw data.
8693 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8695 * Added flags parameter into silc_ske_assemble_security_properties
8696 function in lib/silcske/silcske.[ch].
8698 * Changed notify client operation to fit better for notify messages
8699 sent by server. The notify payload received from server is now
8700 passed to the application (after parsing it to SilcNotifyPayload).
8701 It is application's responsibility to retrieve the arguments
8702 from the payload and show the message the way it wants. The message
8703 sent by server is implementation specific.
8705 * Changed public keys to comply with the protocol specification.
8706 Old public keys are not supported anymore and are not compatible.
8708 * Removed nickname from Channel Payload as the latest draft removed
8709 it. The client must resolve the nickname from the NAMES command
8710 reply received when it joined the channel.
8712 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
8714 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8716 * Fixed some errors in protocol specification drafts.
8718 * Created lib/silccore/silcnotify.c to implement Notify Payload
8719 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
8720 generic payloads described by protocol specifications. The file
8721 includes implementations for ID Payload and Argument Payload.
8723 * Changed Command Payload implementation to use the new Argument
8724 Payload. Changed command_xxxx_payload to command_payload_xxxx
8725 to comply with SILC coding conventions.
8727 * Added suppport for Argument Payload handling in Notify Payload
8728 implementation as protocol requires it. Added the new support
8729 into server and client lib as well.
8731 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8733 * Added support for multiple nicknames on same channel. [n] is
8734 added locally to the nickname if there are more than one same
8735 nicknames on the channel.
8737 * Server now sends all nicknames that matched WHOIS request.
8738 Client also shows the list received from server.
8740 * Added TOPIC command to client side. User can now set and show
8741 current topic on channel.
8743 * Added MOTD command to client and server. Also, server sends the
8744 motd when client connects to the server.
8746 * Changed version strings to comply ISO 8601.
8748 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8750 * Fixed protocol error handling in client library. It should now
8751 cope even if the SKE fails for some reason.
8753 * Made new protocol specification drafts for submitting to IETF.
8755 * Implemented TOPIC command to server in silcd/command.c.
8757 * Added two new notify types into lib/silccore/silcnotify.h:
8758 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
8759 notify nickname change and topic setting/change on a channel.
8761 * API change of command_reply operation in client library. The
8762 application gets now the status type received from server as well.
8764 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8766 * Removed the function just added to lib/silcutil/silcschedule.[ch].
8768 * Cras fixed and optimized the packet handling even further and
8769 it should work now. Minor change to the prototype of function
8770 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
8772 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8774 * Added new function into lib/silcutil/silcschedule.[ch]:
8775 silc_schedule_with_fd to select() a specified fd. The function
8776 returns after timeout expires or data arrives or goes. The
8777 function is used by packet routines to wait that all data is
8778 received from network.
8780 * Fixed data reading from network in lib/silccore/silcpacket.c.
8781 The code now assures that all data is read from the fd and then
8782 continues packet processing. This was a bug fix since the code
8783 used to drop some data in some circumstances.
8785 * Added new function into lib/silcclient/client.[ch]:
8786 silc_client_start_key_exchange to start key exchange after
8787 connection has been established to server. The code internally
8788 now uses this funtion but its main purpose was to provide it
8789 for applications that perform their own connecting. After
8790 application has created a connection it merely calls this
8791 function to start the key exchange between client and server.
8792 The library takes care of everything else after that.
8794 Updated also lib/silcclient/README to explain the usage of
8797 * Do not send to application information that connection has
8798 been established. Application gets notified it by connect
8801 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8803 * Applied cras's patch to add silc_schedule_one function. The
8804 function runs scheduler once and returns.
8806 * Fixed the scheduler after cras messed it up. The timeout
8807 handling works now as it's supposed to work.
8809 * Added into lib/silccore/ silcnotify.h to include notify
8810 message types support. Changed silc_server_send_notify*
8811 functions, in server.[ch], to support those new notify types.
8812 Added the support for the notify types into client library,
8813 as well. Added new notify client operation into ops.h in
8816 * Changed silc_server_packet_send_to_channel to send normal
8817 packets instead of just channel message packets. The function
8818 is now used to send the notify packets to channels. It is not
8819 used to send channel message packets anymore, as server never
8822 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
8823 va_arg()s as it seems to require it nowadays. I guess, if SILC
8824 is compiled with older va_arg() the new code should work anyway.
8826 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8828 * Splitted core library. Core library (lib/silccore) includes
8829 now only SILC protocol specific core (and common) components.
8830 Created new utility library (lib/silcutil) that includes more
8831 generic purpose stuff. The stuff for util library was taken
8832 from the old core library. This was minor and easy split.
8834 * Created SILC Client Library (lib/silcclient) that includes
8835 implementation of the SILC client without user interface. This
8836 was major move from silc/ directory. The code has been changed
8837 so that it is transparent towards the user interface. The
8838 silc/ directory includes now the same user interface as before
8839 and it uses the new client library. Read lib/silcclient/README.
8840 Basicly, the client library performs everything else related
8841 to SILC except user interface handling. Also, configuration
8842 files are considered to be part of user interface and library
8843 does not handle them.
8845 This change also changed a lot of structures, function naming etc.
8846 Most important change was that SilcClientWindow object was
8847 renamed to SilcClientConnection in the client library. Created
8848 also new file lib/silcclient/ops.h. Also added new files
8849 silc/local_command.[ch] and silc/client_ops.[ch].
8851 All these changes were made to make it easier for user interface
8852 designers to create what ever user interface for the SILC client
8855 It is also expected that the server will be moved to lib
8856 directory as well and SILC Server Library will be created;
8857 sometimes in the future.
8859 * Removed Local commands from lib/silccore/silccommand.h as
8860 they are application specific and new client library does not
8861 handle any of those anymore.
8863 * Several functions moved to lib/silcutil/silcutilc.[ch] from
8864 old client implementation in silc/.
8866 * Added support for callback functions in SILC_LOG_* macros.
8867 Application can now set its own callbacks that will be called
8868 instead of using the default functions that will always print
8869 the debug messages to stderr (or stdout). Also, debugging can
8870 now be disabled by setting silc_debug to FALSE and re-enabled by
8871 setting it to TRUE. Note, that logging will still work even
8872 if debugging is disabled.
8874 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
8875 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
8876 silc_log_reset_debug_callbacks.
8878 * To enable debugging in silc client one must give now -d
8879 option on command line.
8881 * Changed silc_schedule_init to automatically allocate task queues
8882 if they are not allocated before calling it.
8884 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8886 * Added GMP 3.1 into math library.
8888 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8890 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
8891 a channel in SILC network. The packet is used by servers and
8892 routers to notify other routers that user has left a channel.
8893 This little feature was missing until now. Added the feature
8894 to protocol specification as well.
8896 Added functions: silc_server_send_remove_channel_user and
8897 silc_server_remove_channel_user into server.[ch].
8899 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
8900 lib/silccore/silcpacket.h. However, they are not implemented
8903 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8905 * Fixed joining to a channel and sending channel messages
8906 between server and router. The channel message sending should
8907 now work inside a cell.
8909 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8911 * Fixed the private message sending between server and router.
8912 The private message sending should now work inside a cell.
8914 * Added silc_server_replace_id into server.[ch] to replace
8915 existing ID in the SILC network.
8917 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
8918 and silc_idlist_replace_server_id into idlist.[ch] in server.
8920 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8922 * Fixed the server to server connections. Server can again now
8923 connect to router. Router to router connections probably does
8926 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8928 * Added dynamic protocol registering support. Now protocols can
8929 registered and unregistered on the fly. Patch by cras.
8931 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8933 * Added lib/contrib directory to hold routines that some platforms
8934 don't have but are needed by SILC.
8936 * Added getopt.c, getopt1.c and getopt.h from GNU C library
8937 into lin/contrib to provide getopt() and getopt_long() for
8938 those who don't have it.
8940 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8942 * Added AWAY command to client. When away message is set and
8943 client receives a private message packet the client automatically
8944 replies to the sender with the away message.
8946 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
8947 bug seemed to be the cause of recent problems when compiling
8950 * Added version detection support to SKE protocol specification
8951 and added the new changes to the SKE implementation as well.
8952 There were other minor changes in the SKE protocol as well.
8954 Many changes in lib/silcske/silcske.[ch] and in
8955 lib/silcske/payload.[ch].
8957 * Added ^U functionality, clear input line. Patch from cras.
8959 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8961 * Mainly small bugfixes on core library. Fixed some debugging
8962 logging and buffer overflow in silclog.c.
8964 * Updated config.sub and config.guess on the distribution tree.
8966 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8968 * Added command lagging support in server. Client may execute
8969 commands now only once in two seconds.
8971 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8973 * Optimized packet reception. MAC computation and checking is now
8974 also more optimized. A lot previously duplicated code is now
8975 used as generic by both client and server.
8977 * Fixed key pair generation in clientutil.c
8979 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8981 * Added into lib/silccore/silcbufutil.[ch] new function;
8982 silc_buffer_realloc.
8984 * Moved generic packet sending/encryption functions to
8985 lib/silccore/silcpacket.[ch] from client and server. Some
8986 rewriting of the functions.
8988 * Moved all generic packet reception/decryption functions to
8989 lib/silccore/silcpacket.[ch] from client and server. The
8990 packet processing is now much cleaner in both client and server.
8991 These were major changes in both client and server.
8993 * Created many common functions in server to do packet sending.
8994 Previously code were duplicated a lot, this has been removed
8997 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8999 * Rewrote major parts of the ID cache system. Don't know
9000 whether it is better now or not but at least the API is more
9003 * Major rewrite on ID cache stuff on client because of the ID
9004 cache API changes. Added idlist.c to client.
9006 * Also major rewrite on ID cache stuff on server as well.
9007 Major rewrite of idlist.[ch]. SilcXXXList's are now named
9008 SilcXXXEntry's. We won't keep anymore idlist specific pointers
9009 in hand, instead they are all put into the ID cache system now.
9010 All server_idlist_* routines uses ID cache now instead of
9011 traversing its own lists (those lists does not exist anymore).
9012 SilcIDList though still exists. Also, SilcXXXEntry's are
9015 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9017 * Finally made the SKE implementation compliant to the protocol
9018 specification. All mp integers are now binary encoded as
9019 opposed being HEX encoded.
9021 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
9024 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
9025 functions: silc_[encode/decode]_pem. Also added function
9026 silc_encode_pem_file to PEM encode with newlines ('\n') for
9029 * SILC public keys are now encoded either PEM or binary. Same
9030 option is for private keys as well. By default private keys
9031 are binary encoded and public keys PEM encoded. Silly HEX
9032 encoding were removed.
9034 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
9035 function to create fingerprints.
9037 * Fixed a bug in SHA1; does not change the original data anymore.
9039 * Partly implemented INFO command on client and server side.
9040 Fixed CLEAR command. Changes to SERVER command; show current
9041 server(s) when giving command without arguments. Added
9042 VERSION command to client.
9044 * Added check to server that unregistered connections cannot
9045 execute commands (unless it is specificly allowed).
9047 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9049 * Fixed screen refresh.
9051 * Fixed channel joining bug from client. On some circumstances
9052 client tried to join to a channel it had already joined.
9054 * Added public key verification process into client's protocol.c.
9055 The client now verifies the public key from user and saves
9056 it into ~./silc/serverkeys/ directory.
9058 Added into: clientutil.[ch]: silc_client_verify_server_key.
9060 * Changed SKE protocol's silc_ske_initiator_finish function
9061 to accept callback function that verifies the received public
9062 key. Removed old silc_ske_verify_public_key function.
9064 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9066 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
9067 silc_pkcs_private_key[_data]_set.
9069 * Made the password and public authentication more cleaner in
9070 server's protocol.c.
9072 * Removed historic and obsolete protocol `channel_auth' from
9073 both client and server.
9075 * Removed wrong way of sending command status messages from
9076 server to client in server's command.c. The old way violated
9077 protocol specification.
9079 Changes to silccore/silccommand.[ch]: removed
9080 silc_command_encode_status_payload -> not needed anymore,
9081 changed silc_command_encode_payload_va to accept extra
9082 argument on variable argument list. The argument type must
9083 now be provided to the function. Also, added new function:
9084 silc_command_encode_reply_payload_va which is same as
9085 normal command_encode_payload_va except command status type
9086 is provided as extra argument.
9088 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9090 * Added ~./silc directory handling. The directory includes the
9091 public and private keys for the client.
9093 Added silc_client_check_silc_dir, silc_client_create_identifier
9094 and silc_client_load_keys.
9096 * Implemented SILC protocol compliant public key. Added public
9097 and private key saving to and loading from files.
9099 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
9100 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
9101 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
9102 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
9103 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
9105 Implemented: silc_pkcs_save_[public/private]_key[_data] and
9106 silc_pkcs_load_[public/private]_key.
9108 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9110 * Added silc_server_get_route (route.[ch]) to get connection
9111 data for the fastest route for given ID.
9113 * Implemented INVITE command on client and server. The command
9114 were re-defined in the SILC Protocol Specification and the
9115 implementation now complies with the specification.
9117 * Implemented PING command on client and server.
9119 * Implemented NAMES command on client and server. The server side
9120 supports currently only normal server not router server yet.
9121 Some changes to NAMES definition in SILC protocol specification.
9123 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9125 * Implemented LEAVE command on client and server.
9127 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
9128 again. This change was made to the protocol as well. Server
9129 should not violate the protocol specification anymore.
9131 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
9133 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
9134 was tested. SOCKS4 was not but should work anyway.
